Detailed ways

As described in the background technology, an image forming device includes an ink cartridge and a printing device. When the ink cartridge is inserted into the printing device, the chip of the ink cartridge cannot be grounded or the grounding is unstable, which affects the grounding stability of the chip and the safety of use. The inventors have found that the reason for this problem is:

During the installation of the ink cartridge, the contact pin group of the printing device is exposed in its installation part. At this time, when the ink cartridge or foreign objects accidentally fall into the installation part and hit the ground contact pin, the ground contact pin may be accidentally bent, the contact point may be damaged by friction, or the position may be unstable, resulting in it being unable to ensure stable contact with the ground sub-terminal of the chip, so that the chip may not be grounded or the grounding may be unstable. Therefore, if the current in the ink cartridge is too large, there is a risk of damaging the chip and the printing device, and it may also cause the printing device to fail to recognize the ink cartridge normally.

In view of the above technical problems, the ink cartridge provided in the embodiment of the present application includes a conductive member and a chip, and the ground terminal of the chip is electrically connected to the conductive member, and is electrically connected to a ground component located in an assembly compartment of a printing device through the conductive member. With such a configuration, when the ink cartridge is inserted into the printing device, the chip is electrically connected to the ground component through its ground terminal and the conductive member, so that the chip is stably grounded.

With such a configuration, the ink cartridge in the embodiment of the present application connects the ground terminal of the chip to the ground component through a conductive component, which can avoid unstable contact between the ground sub-terminal and the ground contact pin, resulting in the chip being unable to be grounded or the grounding being unstable. Therefore, the reliability of the chip grounding can be improved, and excessive current can be prevented from damaging the chip and the printing device, thereby improving the safety of the ink cartridge and the printing device and reducing the occurrence of the printing device being unable to recognize the ink cartridge.

In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of this application.

As shown in Figures 1 to 3, the ink cartridge 10 provided in the embodiment of the present application is one of the consumable parts of the printing device. The consumable parts include but are not limited to the ink cartridge 10. For example, the consumable parts can also be toner cartridges, ribbons, etc. The embodiment of the present application is explained using the ink cartridge as an example.

When the ink cartridge 10 is consumed, it is necessary to replace the ink cartridge 10, so the ink cartridge 10 is usually detachably mounted to the printing device. For example, the printing device in the embodiment of the present application can be called a printer, and the printer has an assembly compartment, and the assembly compartment has a mounting portion 90 for accommodating the ink cartridge and a grounding component, wherein the grounding component is used to ground the printer (also referred to as the printing device). The ink cartridge can be inserted into the mounting portion and electrically connected to the mounting portion of the printer so that the ink cartridge and the printer establish communication.

Specifically, the printing device has an assembly chamber, and the mounting portion is arranged in the assembly chamber. The mounting portion includes a receiving chamber and a stylus assembly, and the grounding component is located at a position outside the position where the stylus assembly is located, wherein the receiving chamber is used for inserting at least one ink cartridge, and at least part of the stylus assembly is exposed in the receiving chamber and is electrically connected to the chip of the ink cartridge. The grounding component and the stylus assembly are two different components, in other words, the grounding component is not a part of the stylus assembly.

The ink cartridge can be detachably installed in the printing device. The printing device has an assembly chamber and a mounting portion and a grounding component arranged in the assembly chamber. The mounting portion includes a accommodating cavity and a contact pin assembly. The grounding component is located at a position other than the position of the contact pin assembly. The ink cartridge includes an ink cartridge body, a chip and a conductive component. The chip is arranged on the ink cartridge body. At least a portion of the ink cartridge body and the chip can be located in the accommodating cavity. The chip is provided with a communication terminal group and a grounding terminal. The communication terminal group is electrically connected to the contact pin assembly. The conductive component is arranged in the assembly chamber, and the conductive component is configured to electrically connect the grounding terminal and the grounding component.

The contact pins in the contact pin assembly can be deformed, while the grounding component cannot be deformed; when the chip contacts the contact pins, at least one contact pin is deformed; when the conductive component contacts the grounding component, the grounding component does not deform. It should be noted that since any two objects abut against each other, their contact surfaces will deform, so the "non-deformable" grounding component in this embodiment refers to the tiny deformation that is invisible to the naked eye when the grounding component contacts the conductive component, compared with the large deformation of the contact pins.

The ink cartridge 10 includes an ink cartridge body 50, a chip 20 and a conducting member, wherein the ink cartridge body 50 is used to hold ink, and the chip 20 is disposed on the surface of the ink cartridge body 50. The chip 20 is used to store information such as the manufacturer information, ink volume information, ink cartridge category information, ink color, etc. of the ink cartridge, and the chip is provided with a plurality of terminals, which can be divided into communication terminals and ground terminals according to the purpose of the terminals, that is, a communication terminal group and a ground terminal are provided on the chip, and the communication terminal group includes a plurality of communication terminals.

Further, the communication terminal is configured to contact and electrically connect with each contact pin of the contact pin assembly. The ground terminal is connected to one end of the conductive member, and the other end of the conductive member can be connected to the grounding component, so that the grounding signal of the chip can be transmitted to the grounding component through the conductive member, thereby completing the grounding.

When the ink cartridge 10 is inserted into the accommodating cavity, each communication terminal of the chip 20 contacts and electrically connects with the corresponding contact pin assembly, so that data transmission, confirmation, data interaction, etc. can be performed between the ink cartridge 10 and the printer. At the same time, the conducting component is electrically connected to the grounding component, so that the ink cartridge and the printer are both grounded.

Compared with the related art, compared with the solution in which the grounding sub-terminal of the chip 20 is electrically connected to the corresponding grounding contact pin in the contact pin assembly, the ink cartridge in the embodiment of the present application connects the grounding terminal of the chip to the grounding component through a conductive component, which can avoid unstable contact between the grounding terminal and the grounding contact pin, which may cause the chip to be unable to be grounded or unstable in grounding. Therefore, the reliability of the chip grounding can be improved, and the chip and the printing device can be prevented from being damaged by excessive current, thereby improving the safety of the chip and the printing device and reducing the occurrence of the printing device being unable to recognize the ink cartridge.

On the basis of the above embodiments, in the embodiments of the present application, the mounting part can be fixed in the assembly bin, or the mounting part can be movably mounted in the assembly bin, for example, the mounting part is slidably mounted in the assembly bin. However, due to the different arrangements of the mounting part in the assembly bin, the installation method between the ink cartridge and the mounting part is affected, and thus the arrangement of the chip on the ink cartridge and the electrical connection scheme of the conductive component and the grounding component are also different. This application introduces this in different embodiments.

Embodiment 1:

In the embodiment of the present application, the mounting portion is disposed in the assembly bin, and the grounding component is disposed in the accommodating cavity of the mounting portion; specifically, the mounting portion can be movably mounted in the assembly bin.

In the first embodiment, an antenna-type conductive component is provided in this embodiment, and the metal part arranged in the assembly bin is configured as a grounding part, that is, the metal part is grounded; one end of the conductive component is electrically connected to the ground terminal of the chip 20, and the other end is connected to the grounding part, and the electrical connection point between the two is located above the chip.

Continuing to refer to FIG. 3 , the mounting portion is a component of the printing device, which is used to carry multiple or one ink cartridge. The ink cartridge is detachably mounted in the mounting portion along the mounting direction P. When the ink cartridge is used up, it needs to be replaced with a new ink cartridge.

The ink cartridge 10 includes a chip 20, a handle 30, an ink outlet 41, and an ink cartridge body 50. The mounting portion 90 includes a stylus assembly 91, an ink supply portion 92, an opening 95, and a bottom wall 90a. The ink cartridge 10 is mounted in the mounting portion 90 from the opening 95 along the mounting direction P (-Z axis direction). The handle 30 is used to fix the ink cartridge 10 to the mounting portion 90 to prevent the ink cartridge 10 from being separated from the mounting portion 90.

The cartridge body 50 (also referred to as the ink cartridge main body 50 ) stores ink, and the ink reaches the ink supply portion 92 through the ink outlet 41 , and then the ink supply portion 92 can supply the ink to the print head of the printer, so that the ink can be used to perform printing.

As shown in Fig. 4, the contact pin assembly 91 includes a contact pin 91a and a base 910, and the contact pin 91a is disposed on the base 910. The chip 20 has a communication terminal group, which can be electrically connected to the contact pins of the contact pin assembly for mutual transmission of electrical signals.

In this embodiment, a three-dimensional rectangular coordinate system, i.e., an XYZ axis coordinate system, is set, and the three-dimensional rectangular coordinate system of the ink cartridge is consistent with the three-dimensional rectangular coordinate system of the mounting portion. The direction in which the ink cartridge 10 is installed to the mounting portion is the -Z axis direction, and the direction in which the ink cartridge is separated from the mounting portion is the +Z axis direction, the opening is located in the +Z axis direction, and the bottom wall 90a is located in the -Z axis direction. In general, the printer is placed flat on an office desktop or a printing desktop, the opening 95 is located at the top of the mounting portion 90, and the bottom wall 90a is located at the bottom of the mounting portion 90. This arrangement is convenient for users to install or remove the ink cartridge.

For example, the mounting portion 90 has four mounting positions, each mounting position can be inserted into one mounting position, and the four ink cartridges can store four different colors of ink, such as black, yellow, blue, and red.

The mounting portion provided in this embodiment is a component with an opening that is approximately a rectangular parallelepiped or a cube, and the inner side wall and the bottom wall 90a of the mounting portion constitute the mounting position. The stylus assembly 91 is mounted on the first side wall 90c of the mounting portion, and the mounting positions are arranged in sequence in the Y-axis direction, and the four mounting positions are arranged in sequence in the Y-axis direction. The direction that is perpendicular to the Y-axis and the Z-axis at the same time is the X-axis direction, wherein the direction from the inside of the mounting portion 90 to the stylus assembly 91 is the +X-axis direction. The +X-axis is perpendicular to the first side wall 90c, and when viewed along the +X-axis direction, on the YZ plane, when the +Z-axis is at the top, the +Y-axis direction is on the left.

Continuing to refer to FIG. 4 , the stylus assembly 91 comprises: a base 910 and a plurality of stylus pins mounted on the base 910. For example, five stylus pins are arranged on the base 910, and the five stylus pins are respectively the first stylus pin 911 to the fifth stylus pin 915. Each stylus pin is a thin sheet of metal, which can play a conductive role and is not easy to wear. Accordingly, the base 910 has a plurality of slits 981-985 corresponding to the stylus pins. Among them, the slits 981, 982, 983, 984, 985 correspond to the stylus pins 911, 912, 913, 914, 915, respectively. The plurality of slits 981-985 are all U-shaped, and have a slit opening in the +Z axis direction. The plurality of stylus pins 911-915 are respectively installed in the slits 981-985 through the slit opening along the -Z axis direction.

Specifically, the first contact pin 911 is installed in the first slit 981 through the slit opening along the -Z axis direction; the installation method of the second contact pin 912 to the fifth contact pin 915 is the same, and will not be repeated here. One side of each of the first contact pin 911 to the fifth contact pin 915 is connected to the main circuit of the printer through the internal circuit of the installation part, and the other side is exposed in the accommodating cavity of the installation part 90, and when the ink cartridge is inserted into the accommodating cavity, it can be electrically connected to each communication terminal of the chip 20.

The structures of the first contact pin 911 to the fifth contact pin 915 in the embodiment of the present application are consistent. This embodiment takes the first contact pin 911 as an example to illustrate the structures of each contact pin. As shown in FIG5 , the first contact pin 911 is divided into a first part 911a, a second part 911b and a third part 911c. The first part 911a is used to electrically connect to the communication terminal of the chip 20 and form a first contact portion; the second part 911b is connected to the internal circuit of the printer.

The first contact pin 911 is fixed to the first slit 981 through the third part 911c or a part of the third part 911c (for example, the horizontal part 911h of the third part 911c). The first part 911a and the second part 911b are arranged at the ends of the first contact pin 911 in the -Z axis direction, so that the first part 911a and the second part 911b can be elastically deformed and easily restored to their original state after deformation. The first part 911a of the first contact pin 911 is arranged in the -X axis direction, and the second part 911b is arranged in the +X axis direction. The first part 911a and the second part 911b protrude from the base 910, and the third part 911c does not protrude from the base 910.

Furthermore, the first portion 911a and the second portion 911b protrude from the base 910 in the X-axis direction, and the base 910 is located between the first portion 911a and the second portion 911b. The first portion 911a is closer to the mounting position than the second portion 911b, that is, the first portion 911a can be electrically connected to the chip 20.

The third portion 911c includes a first vertical portion 911k and a second vertical portion 911j perpendicular to the X-axis direction, and a horizontal portion 911h parallel to the X-axis direction, wherein the horizontal portion 911h connects the first vertical portion 911k and the second vertical portion 911j. The first vertical portion 911k and the second vertical portion 911j extend up and down along the Z-axis direction. The first vertical portion 911k is closer to the mounting position than the second vertical portion 911j, the end of the first vertical portion 911k is connected to the first portion 911a, the end of the second vertical portion 911j is connected to the second portion 911b, and the horizontal portion 911h or the first vertical portion 911k and the second vertical portion 911j are fixed to the first slit 981 in the +Z-axis direction.

Continuing to refer to FIG. 5, the first portion 911a includes a first surface portion 911a1, a second surface portion 911a2, a third surface portion 911a3 and a fourth surface portion (not shown in the figure), wherein the third surface portion 911a3 and the fourth surface portion are arranged opposite to each other along the X direction, the first surface portion 911a1 and the second surface portion 911a2 enclose an area to form a ridge region, the first vertical portion 911k is the vertical region, the second portion 911b is another ridge region, and the second vertical portion 911j is another vertical region. The second contact pins 912 to the fifth contact pins 915 have the same arrangement and structure as the first contact pin 911, and will not be described in detail here.

As shown in Figures 6 and 7, the chip 20 provided in this embodiment has a memory 100, a substrate 120, and a plurality of terminals 130 (communication terminal group). The substrate 120 has a front surface 120a, a rear surface 120b, a left side 120c, a right side 120d, a top surface 120e (not shown in the figure), and a bottom surface 120f.

Among them, the front surface 120a is arranged opposite to the rear surface 120b, and the front surface 120a is located on the +X side of the rear surface 120b; the left side surface 120c is arranged opposite to the right side surface 120d, and the left side surface 120c is located on the -Y axis side of the right side surface 120d; the top surface 120e and the bottom surface 120f are arranged opposite to each other, and the top surface 120e is located on the +Z axis side of the bottom surface 120f.

Further, a plurality of terminals 130 are disposed on the front surface 120a, so the front surface 120a is also referred to as a first terminal surface. For example, a first terminal 131, a second terminal 132, a third terminal 133, and a fourth terminal 134 are disposed on the front surface 120a, and the first terminal 131, the second terminal 132, the third terminal 133, and the fourth terminal 134 are all at different positions on the Y axis, the first terminal 131 and the fourth terminal 134 are at the same position on the Z axis, the second terminal 132 and the third terminal 133 are at the same position on the Z axis, but the first terminal 131 and the third terminal 133 are at different positions on the Z axis.

Furthermore, the first terminal 131, the second terminal 132, the third terminal 133 and the fourth terminal 134 are all configured as communication terminals. The first terminal 131 (data terminal) is configured to send or receive a data signal; the second terminal 132 (clock terminal) is configured as a clock terminal for receiving a clock signal; the third terminal 133 (power supply terminal) is configured to provide an operating voltage to the memory 100; and the fourth terminal 134 (reset terminal) is used to reset the internal data of the memory 100.

Each communication terminal has a contact portion C, which is represented by a circle. Multiple communication terminals have multiple contact portions C, which are respectively the first contact portion C1 to the fourth contact portion C4. The contact portion C is the most likely contact area of the contact pin on the terminal 130 when the ink cartridge 10 is installed on the printer.

The communication terminal group includes a data terminal (first terminal 131), a reset terminal (fourth terminal 134), a power terminal (third terminal 133), and a clock terminal (second terminal 132); along the installation direction P of the ink cartridge 10 to the printing device, the contact parts C1-C4 of each terminal of the communication terminal group that contact the contact pin assembly are arranged in two rows.

In the installation direction P (ie, the Z-axis direction in the figure), the contact portion C1 of the data terminal and the contact portion C4 of the reset terminal are arranged on the upstream side; the contact portion C3 of the power terminal and the contact portion C2 of the clock terminal are arranged on the downstream side.

In the embodiment of the present application, the memory 100 and the above-mentioned communication terminal are respectively arranged on the substrate 120, and the memory 100 needs to be grounded and can be regarded as a "ground terminal". The memory 100 needs to transmit and interact with the printing device for grounding signals so that the ink cartridge can be normally installed in the printing device and perform corresponding tasks.

It should be noted that the memory 100 is used to store information such as manufacturer information, ink volume information, ink cartridge category information, ink color, etc. When the ink cartridge 10 is installed in the installation part of the printer, data transmission, confirmation, data interaction, etc. will be performed between the memory 100 and the printer, and the two are realized through the connection between the communication terminal and each contact pin of the printer.

Further, the memory 100 can be arranged on any one or several surfaces of the front surface 120a to the bottom surface 120f. Preferably, the memory 100 is arranged on the rear surface 120b. The specific shape and structure of the substrate 120 are not limited, and those skilled in the art can set it according to specific design requirements. For example, the chip 20 can be set to a rectangular structure, a cut-corner rectangular structure, a rounded rectangular structure, a T-shaped structure, a trapezoidal structure, or a parallelogram structure.

In addition, there is no limitation on the location of the memory 100 on the substrate 120. For example, the memory 100 can be set on the side of the chip 20 near the rear end in the direction of the -Z axis, or the memory 100 can be set on the side of the chip 20 near the front end in the direction of the +Z axis, or the memory 100 can be set in the middle of the chip 20. Those skilled in the art can make settings according to specific design requirements, which will not be repeated here.

Continuing to refer to FIG. 6 , in this embodiment, the memory 100 is disposed on the rear surface 120b and is disposed near the right side surface 120d and the top surface 120e. The connector 135 (also referred to as a conducting member) is made of a conductive material having a certain hardness and is connected to the conductive sheet 135a (also referred to as a grounding terminal) by soldering. The conductive sheet 135a (also referred to as a grounding terminal) is connected to the memory 100 through the circuit/conductive wire built into the substrate 120, thereby connecting the connector 135 to the memory 100.

The conductive sheet 135a (also called the ground terminal) can be regarded as a part of the chip 20. Specifically, the conductive sheet 135a (also called the ground terminal) can be copper-clad (realized by electroplating process) on the chip 20, and can electrically connect the conductive component 135 and the memory 100. The connector 135 (also called the conductive component) can be welded or abutted or in other contact forms with the conductive sheet 135a (also called the ground terminal), as long as it can be electrically connected.

The connector 135 (also referred to as a conducting member) is disposed in the assembly compartment, and the connector 135 is configured to electrically connect the conductive sheet 135a (also referred to as a grounding terminal) and the grounding component. Further, the ink cartridge 10 and the printing device transmit a grounding signal through the grounding terminal 135a, the conducting member 135, and the grounding component. Optionally, the ink cartridge 10 and the printing device transmit a grounding signal through the memory 100 on the chip, the conducting member 135, and the grounding component. Further, the ink cartridge 10 and the printing device transmit a grounding signal through the memory 100 on the chip, the grounding terminal 135a, the conducting member 135, and the grounding component.

Since the connector 135 (also referred to as a conducting member) is electrically connected to the chip memory 100 and the ground terminal 135a, the connector 135 (also referred to as a conducting member) can also be regarded as the chip 20. That is, the chip 20 includes: the memory 100, the substrate 120, the communication terminal group 130, the conducting member 135, and the ground terminal 135a.

The contact pins 911-914 in the contact pin assembly 91 can be deformed, but the grounding component cannot be deformed; when the chip 20 contacts the contact pins 911-914, at least one contact pin is deformed; when the conductive member 105 contacts the grounding component, the grounding component does not deform, and even tiny deformations that are invisible to the naked eye are also considered non-deformable. This structure is beneficial for ensuring the stability of the transmission of the electrical signals of the chip 20, especially the grounding signals.

It should be noted that the ground signal is usually output by the main CPU of the printing device, and the ground signal is output by the main CPU to the ground contact pin of the contact pin assembly, the ground component, etc. When the ink cartridge is installed on the printing device, the ground signal must be interconnected between the ink cartridge and the printing device. In the related art, the ground signal is transmitted between the ink cartridge and the printing device through the ground sub-terminal and the ground contact pin of the chip terminal group in sequence.

However, in the present application, the ground signal is transmitted through the ground terminal, the conductive component, and the ground component. Optionally, the present application transmits the ground signal through the memory on the chip, the conductive component (also referred to as the connector), and the ground component. Optionally, the present application transmits the ground signal through the memory on the chip, the ground terminal, the conductive component (also referred to as the connector), and the ground component, which can improve the stability of the ground signal transmission.

This embodiment describes in detail the layout of the communication terminal group and the grounding terminals provided on the chip on the chip substrate.

As shown in FIG7 , in this embodiment, the chip 20 includes a substrate 120, and the substrate 120 includes a first surface 120a and a second surface 120b that are arranged opposite to each other, wherein the first surface 120a is the front surface of the substrate 120, and the second surface 120b is the rear surface of the substrate. The first surface 120a is configured as a surface of the substrate close to the stylus assembly 91 of the printer, and the first surface 120a is provided with a communication terminal group, and the communication terminal group includes a plurality of communication terminals 131-134.

Furthermore, the chip further includes a ground terminal 135 a , which is disposed on the first surface 120 a or the second surface 120 b , and is electrically connected to the conductive component 135 , and forms a grounding point of the chip.

In one embodiment, the first surface 120a has a first direction and a second direction that are orthogonal to each other, and the first direction is configured as the installation direction of the ink cartridge 10 installed on the printing device. Each of the communication terminals has a first contact portion formed by contact with the contact pin, and has a first projection relative to the first surface 120a. The first projections of the plurality of first contact portions on the first surface 120a enclose a first area, and the grounding point formed by the conductive member and the grounding terminal has a second projection on the first surface 120a.

Along the second direction, at least part of the second projection is located outside the first area. In other words, in the second direction, part of the second projection is located in the first area, and at least part of the second projection is located outside the first area. For example, part of the second projection is located outside the first area. In this case, in the second direction, the second projection is close to one side of the first area, and the distance between the second projection and the first area is less than the length of the first area. Optionally, in the second direction, the second projection overlaps with the first area.

The chip 20 may also have the following variations, and different chip variations may be installed on the ink cartridge 10 .

Chip modification example 1:

As shown in FIG. 8 to FIG. 10 , the difference between the chip of this variation and the chip of the first embodiment is that the chip 20 provided in this variation has a memory 100 , a substrate 120 , and a terminal group (equivalent to the communication terminal group of the first embodiment).

The memory 100 and the terminal group (equivalent to the communication terminal group of the first embodiment) are arranged on the chip substrate 120, and the memory 100 is used to store information such as the manufacturer information, the ink volume information, the consumable box category information, the ink color, etc. When the consumable box 10 is installed in the installation part 90 of the printer, data transmission, confirmation, data interaction, etc. will be performed between the memory 100 and the printer, and the two are realized through the connection between the terminal group and the printer contact pin. Furthermore, the shape of each terminal in the terminal group can be other shapes, such as: rectangular, square, circular, trapezoidal or other irregular shapes.

In this variation, a terminal group is provided on the front surface 120a, and the terminal group includes a plurality of terminals (131-139). Of course, the memory 100 can be provided on any one or several surfaces of the front surface 120a-bottom surface 120f, and in the Z-axis direction, the top surface 120e and the bottom surface 120f are relatively arranged. The specific shape and structure of the chip 20 are not limited, and those skilled in the art can set it according to specific design requirements, such as the chip 20 can be set to a rectangular structure, a cut-corner rectangular structure, a rounded rectangular structure, a T-shaped structure, a trapezoidal structure, or a parallelogram structure.

In addition, there is no limitation on the location of the memory 100. For example, the memory 100 can be set on the side of the chip 20 close to the rear end of the installation direction, or the memory 100 can be set on the side of the chip 20 close to the front end of the installation direction, or the memory 100 can be set in the middle of the chip 20. Those skilled in the art can make settings according to specific design requirements, which will not be repeated here.

In this embodiment, the terminal group includes 9 terminals, and the functions and effects of each terminal are as follows: a first terminal 131; a second terminal 132 (reset terminal): used to reset the internal data of the chip; a third terminal 133 (clock terminal): used to receive a clock signal; a fourth terminal 134; a fifth terminal 135; a sixth terminal 136 (power terminal): used to receive a power potential different from the ground potential (for example, 3.6V), and provide power for the operation of the memory 100 through this terminal; a seventh terminal 137a, 137b, 137c, 137d (ground terminal): used to indirectly receive the ground potential; an eighth terminal 138 (data terminal): used to send or receive data signals, and a ninth terminal 139.

In this embodiment, the third terminal group includes a first terminal 131 and a fourth terminal 134, and the second terminal group includes a fifth terminal 135 and a ninth terminal 139. The third terminal group and the second terminal group are both installation detection terminals, wherein the first terminal 131 and the fourth terminal 134 may also be short circuit detection terminals, and the other terminals are the first terminal group. When the consumable box 10 is installed on the printer, an electrical signal is transmitted between the installation detection terminal and the printer to detect whether the consumable box 10 is installed. In addition, the fifth terminal 135 and the ninth terminal 139 are also called high-voltage terminals, which are used to receive an installation detection voltage (such as 42V) to complete the installation detection function of the consumable box installed on the installation portion.

For example, a high resistor (e.g., 62 kΩ) is connected between the fifth terminal 135 and the ninth terminal 139, and the change in current or voltage is detected to determine whether the consumable box 10 has been installed in the installation portion. The first terminal 131 and the fourth terminal 134 are also called short circuit detection terminals. The voltage change on the terminals is detected to detect whether there is a short circuit on the chip 20; at the same time, whether the consumable box 10 is installed on the printer can be determined by whether the two are connected.

In addition, the first terminal 131 and the fourth terminal 134 are also used to detect whether a short circuit occurs between the terminals, specifically, to detect whether a short circuit occurs between the fifth terminal 135/the ninth terminal 139 and the first terminal 131/the fourth terminal 134. When a short circuit occurs between the fifth terminal 135/the ninth terminal 139 and the first terminal 131/the fourth terminal 134, the printer can detect that the voltage on the first terminal 131/the fourth terminal 134 is increased, and then the printer prompts a short circuit information, thereby avoiding the risk of the chip or the printer being damaged due to the short circuit.

Each terminal in the terminal group has a respective contact portion, represented by a dot in Figure 8. The contact portion is the most likely contact area of the contact pin on the terminal when the consumable cartridge 10 is installed in the printer. When observed in a direction perpendicular to the installation direction P, the arrangement order is a ground terminal (seventh terminal 137a, 137b, 137c, 137d), a second contact portion, a third contact portion, a first contact portion, another third contact portion, another second contact portion, or the ground terminal and the fifth terminal 135 are in a straight line along the Z direction (as shown in FIG8). Of course, the ground terminal can be set on the front surface 120a of the chip or on the rear surface 120b. For example, the ground terminal can be arranged in the four positions of 137a, 137b, 137c, and 137d shown in FIGS. 8 and 9. In the present embodiment, the ground terminals 137a, 137b, 137c, and 137d are preferably set on the front surface 120a or the rear surface 120b. The arrangement method is that the ground terminal is located in the +Z direction of the fifth terminal 135 or in the +Z direction toward the -Y direction side.

Optionally, along the Z direction, the ground terminal (seventh terminal) and the first terminal 131 are in a straight line. Optionally, along the Z direction, the ground terminal (seventh terminal) overlaps with at least a portion of the first terminal 131 and the fifth terminal 135. Optionally, along the Z direction, the ground terminal (seventh terminal) overlaps with at least a portion of the first terminal 131. Optionally, along the Z direction, the ground terminal (seventh terminal) overlaps with at least a portion of the fifth terminal 135. Optionally, along the Z direction, the ground terminal (seventh terminal) overlaps with at least a portion of the fourth terminal 134 and the ninth terminal 139. Optionally, along the Z direction, the ground terminal (seventh terminal) overlaps with at least a portion of the fourth terminal 134. Optionally, along the Z direction, the ground terminal (seventh terminal) overlaps with at least a portion of the ninth terminal 139. The ground terminal (seventh terminal) is electrically connected to the memory 100 and the conductive member 140.

As shown in Figure 11, in this embodiment, the memory 100 is arranged on the rear surface 120b. On the rear surface 120b of the substrate 120, close to the right side 120d and the top surface 120e, the connector 140 (equivalent to the conductive component of the first embodiment, made of a conductive material with a certain hardness) is connected to the conductive sheet 140a (equivalent to the ground terminal of the first embodiment) through soldering/abutment. The conductive sheet 140a is a contact prefabricated on the rear surface 120b of the substrate. This contact is connected to the memory 100 through a conductive wire arranged inside the substrate 120, thereby realizing the electrical connection between the connector 140 and the memory 100.

Chip variation example 2:

The chip of this variant example is different from that of the first embodiment in that: as shown in FIGS. 12 and 13 , the terminal group 130 on the substrate includes four communication terminals, which are respectively defined as a first terminal 131, a second terminal 132, a third terminal 133 and a fourth terminal 134, wherein the first terminal 131 (data terminal) is used for sending or receiving data signals; the second terminal 132 (clock terminal) is used for receiving clock signals; the third terminal 133 (power terminal) is used for receiving a power potential different from the ground potential (such as 3.6V/3.3V), and power is provided for the operation of the memory through this terminal; the fourth terminal 134 (reset terminal) is used for resetting the internal data of the chip or adjusting the processing device to a responsive state.

Each contact portion C1-C4 has a first projection on the first surface, wherein the first surface includes a first direction and a second direction that are orthogonal to each other; wherein the first direction is configured as an installation direction P of the ink cartridge to be installed on the printing device, in which case the first surface is parallel to the first direction (i.e., the installation direction P); or, the first direction is configured as an extension direction of a projection line of the installation direction P of the ink cartridge to be installed on the printing device on the first surface, and the first surface may be inclined relative to the first direction, i.e., the substrate is obliquely arranged on the ink cartridge body.

For example, the first direction in the figure is the Z-axis direction, the X-axis direction is the second direction, and the second direction is perpendicular to the first direction. In this case, the first surface can be the front surface 120a or the rear surface 120b of the substrate. The first projection of each of the above-mentioned contact portions on the first surface encloses a first region M. For example, the substrate includes a region Q1 and a region Q2 arranged along the center line of the substrate, and the first region M is located in the region Q1, the first terminal to the fourth terminal are all located in the region Q1, and each of the formed contact portions is in the first region M, and of course the first region is also located in the region Q1.

Furthermore, the rear surface of the substrate is also provided with a grounding terminal, which can be called a fifth terminal/additional terminal, wherein the grounding terminals 135a, 135b, 135c, 135d (equivalent to the grounding terminals of the first embodiment) are connected to the conductive member and the memory, and the grounding terminal is connected to the conductive member and forms a grounding point. The grounding terminal can be arranged at four positions: 135a, 135b, 135c, and 135d.

For example, the first terminal to the fourth terminal are all located in the region Q1. Furthermore, the region Q2 can be eliminated or minimized, thereby reducing the size of the chip and miniaturizing the chip, ink cartridge, and printer. When the region Q2 is eliminated or minimized, the region Q1 refers to the chip region where the first terminal 131 to the fourth terminal 134 are located, and the contact portion of the first terminal 131 to the fourth terminal is within the first region M.

The positions of the grounding terminals 135a, 135b, 135c, and 135d may be on the region Q1 on the rear surface 120b. For example, as shown in FIG. 13 , the first additional terminal 135a or the second additional terminal 135b is at the position shown, and the second projection of the grounding point formed in this case is located in the region Q1 on the first surface, and the second projection partially overlaps with the first region M. Alternatively, the position of the fifth terminal 135 may be on the region Q1 on the front surface 120a, for example, at the position shown by the fourth additional terminal 135d, and the second projection of the grounding point formed in this case is located in the region Q1 on the first surface, that is, the second projection is located outside the first region M.

In other embodiments, the fifth terminal 135 may be located on the second region Q2 on the rear surface 120b. For example, at the position shown in the third additional terminal 135c shown in FIG. 13, the second projection of the grounding point formed in this case is located outside the first region Q1 on the first surface, that is, the second projection is located outside the first region M. Further, in some embodiments, the width of the region Q2 in the X-axis direction may be smaller than the width of the region Q1, and the distance between the side of the second projection close to the first region M and the first region may be smaller than the length of the first region.

Chip variation 3:

The third variation is similar to the first variation of the chip, except that: as shown in FIG. 14 and FIG. 64, in another embodiment, eight terminals are provided on the front surface 120a of the substrate in this embodiment. Seventh terminals 137a and 137b are provided on the rear surface 120b of the substrate 120 as grounding terminals, and the seventh terminals can also be provided at other positions on the rear surface 120b for receiving the grounding potential. In addition, the seventh terminals only need to be provided on the rear surface 120b, and there is no restriction on the number and shape. The chip 20 in this variation has two substantially rectangular seventh terminals.

The ground terminal may be located within region Q1, such as the location of the ground terminal 137a shown in FIG64; the ground terminal may be located within region Q2, such as the location of the ground terminal 137b shown in FIG64.

It should be noted that the contact pin assembly includes 8 contact pins, each of which contacts each terminal on the front surface and forms a respective contact portion, which is represented by a dot in Figure 14. The contact portion is the most likely contact area of the contact pin on the terminal when the ink cartridge 10 is installed on the printer.

As shown in FIG64 , the first projections formed by the contact portions on the first surface enclose the first region M, and the grounding terminal and the conductive member are connected to form a grounding point, and the projection of the grounding point on the first surface is a second projection, wherein when the grounding point is formed by the grounding terminal 137a, the second projection is at least partially located in the first region M and at least partially located outside the first region M, that is, the second projection at least partially overlaps with the first region M. When the grounding point is formed by the grounding terminal 137b, the second projection is at least partially located in the first region M and at least partially located outside the first region M, that is, the second projection at least partially overlaps with the first region M.

As shown in Figures 7 and 15, the chip 20 has a positioning hole, and the ink cartridge body 50 is provided with a positioning column that cooperates with the positioning hole. When the positioning hole of the chip 20 is inserted into the positioning column, the positioning of the chip 20 can be completed, and the chip 20 can be further fixed to the ink cartridge body 50 by welding.

Specifically, in this embodiment, the chip 20 has a first hole 121 and a second hole 122. The first hole 121 and the second hole 122 are both through holes on the substrate 120, and both penetrate the front surface 120a and the rear surface 120b of the substrate 120.

The first hole 121 is a rectangular recessed portion formed by the top surface of the substrate and the bottom surface 120f, and the second hole 122 is a through hole portion located on the 120a/120b side of the substrate 120 near the bottom surface 120f. Correspondingly, a chip mounting portion is provided on the ink cartridge corresponding to the chip, and the chip mounting portion includes a first positioning column 601 matched with the first hole 121 and a second positioning column 602 matched with the second hole 122. The first positioning column 601 and the second positioning column 602 are respectively combined with the first hole 121 and the second hole 122 in a plug-in manner, and then the chip 20 is fixed to the cartridge body 50 (also referred to as the ink cartridge body 50) by means of hot welding. Such a setting can prevent the chip 20 from being offset during the installation process or the use process, and specifically can achieve positioning in the three directions of the X axis, the Y axis, and the Z axis.

It is understandable that the number of the above-mentioned positioning holes is not limited here. Specifically, only one positioning hole (for example, the first hole 121) can be provided, or two or more positioning holes can be provided. In addition, the shape of the positioning hole is not limited. The positioning hole can be a circular hole, a square hole, or a hole of an irregular shape. Similarly, the specific shape and number of the positioning column and the limiting portion are not too limited here.

On the basis of the above-mentioned embodiments, the ink cartridge body of the embodiment of the present application is provided with a fixing assembly 603 on the -Y-axis side of the handle 30, and the fixing assembly 603 includes a first fixing member 603a, a second fixing member 603b, and a third fixing member 603c. The third fixing member 603c restricts the connecting member 135 (also referred to as a conducting member) on the ink cartridge body 50. The first fixing member 603a and the second fixing member 603b are arranged opposite to each other, and can clamp the connecting member 135 and bend the connecting member 135 at a right angle and fold it in a direction away from the ink cartridge body 50.

Such a configuration can achieve the fixation of the connector 135 (also referred to as a conducting member) to prevent the connector 135 from swinging and causing poor contact between the connector 135 and the grounding component (not shown) on the printer. Furthermore, the connector 135 is bent at a right angle, which is conducive to adjusting the connector 135 to extend toward the grounding component of the printer, making it convenient to electrically contact the grounding component of the printer, preventing excessive current, and reducing the probability of electric shock caused by unstable grounding.

As shown in FIG. 16 , when the ink cartridge 10 having the chip 20 of this embodiment is installed in the mounting portion 90 , the first terminal 131 - the fourth terminal 134 are electrically connected to the second surface portions 911a2 - 914a2 of the corresponding first portions 911a - 914a of the first contact pin 9111 - the fourth contact pin 914 , respectively.

Continuing to refer to Figures 1 and 2, when the ink cartridge 10 is installed in the installation portion, one end of the connector 135 is connected to the ground terminal set on the rear surface 120b of the substrate, and the ground terminal is electrically connected to the memory 100. The connector 135 extends from the rear surface 120b of the substrate and extends in the +Z axis direction close to the ink cartridge body 50. The first fixing member 603a and the second fixing member 603b act on the portion of the connector 135 that is bent into a right angle, so that the connector 135 turns toward the metal part of the printer (also referred to as the grounding part). It should be noted that the metal part in the embodiment of the present application can be a part of the grounding part, or it is the grounding part. The metal part is set in the assembly bin of the printer, and the metal part (also referred to as the grounding part) is grounded, and a grounding signal is transmitted on the metal part.

Furthermore, the connector 135 is electrically connected to the grounding component of the printer and is grounded through the grounding component. With this arrangement, the electrical connection position between the grounding component and the conductive component is located above the chip, and the chip grounding has good stability, which improves the safety of chip use and reduces the occurrence of the situation where the printing device cannot recognize the ink cartridge. The connector 135 (conductive component) is in contact with and electrically connected to the conductive wall plate 81 at the end 135e (as shown in FIG. 15). Specifically, the end 135e (as shown in FIG. 15) of the connector 135 (conductive component) on the +X axis side is in contact with and electrically connected to the conductive wall plate 81.

In the embodiment of the present application, the mounting portion 90 can be movably mounted in the assembly bin, and the grounding component is arranged outside the mounting portion, and part of the conductive component is arranged in the accommodating cavity of the mounting portion and is electrically connected to the grounding terminal of the chip; part of the conductive component is arranged outside the mounting portion and is used to be electrically connected to the grounding component, that is, the grounding terminal of the chip of the ink cartridge is electrically connected to the grounding component through the conductive component to realize the transmission of the grounding signal.

Each chip can be adapted to ink cartridges of different embodiments and implementations.

Furthermore, since the mounting part is slidably mounted on the grounding rail, in order to ensure the smooth sliding of the mounting part, the position where the conductive member contacts the grounding component in the embodiment of the present application can be configured as a ball or a ball bearing, and the ball and the ball bearing are part of the conductive member and are electrically connected to the conductive member. Such a configuration can reduce the friction between the contacting position and the conductive member, and ensure that the mounting part and the ink cartridge slide smoothly on the grounding rail.

The conducting member can also be regarded as a part of the chip. When the conducting member is regarded as a part of the chip, the chip can be detachably installed in the printing device. The printing device has an assembly bin and a mounting part and a grounding part arranged in the assembly bin. The mounting part includes a receiving cavity and a stylus assembly. The grounding part is located outside the position of the stylus assembly. The chip has a communication terminal group, a conducting member (also called a connector), and a memory. The communication terminal group is electrically connected to the stylus assembly. The conducting member is electrically connected to the grounding part and the memory. The chip can also achieve the beneficial effects of the present application.

It should be noted that the grounding component and the contact pin assembly are two different components. Further, the chip is arranged on the ink cartridge body, the ink cartridge body and at least a part of the chip can be located in the accommodating cavity, and the conducting component is arranged in the assembly chamber.

Second implementation of Example 1:

The difference between the embodiment of the present application and the aforementioned implementation is that:

As shown in Figures 17 to 20, the grounding component provided in the embodiment of the present application includes a grounding rail 80, and the grounding rail 80 is grounded. The grounding rail 80 is arranged in the assembly bin, and the mounting portion 90 can be slidably arranged on the grounding rail 80, that is, the grounding rail 80 not only serves as a bearing component of the mounting portion 90, but also serves as a grounding component to transmit a grounding signal.

In one embodiment, a conductive wall plate 81 is provided on one side of the grounding rail 80 facing the mounting portion, and the conductive wall plate 81 is connected to the grounding component, and the two can be an integral structure, which is not limited in the embodiment of the present application. The length extension direction of the conductive wall plate 81 is consistent with the extension direction of the grounding rail 80, and the conductive wall plate 81 intersects with the horizontal plane, for example, the conductive wall plate 81 is perpendicular to the horizontal plane, or the conductive wall plate 81 is inclined relative to the horizontal plane.

Specifically, in this embodiment, the ink cartridge 10 also has a connector 135 (equivalent to a conducting member), which is used to connect the chip 20 and other metal parts on the printing device (equivalent to a grounding member) to achieve the grounding function of the chip 20, that is, the connector 135 is configured as a conducting member. For example, the connector 135 includes a connecting body 135bb and a conductor 135cc, wherein the connecting body 135bb and the conductor 135cc can be integrally arranged or separately arranged, and the embodiment of the present application does not limit this. The connector 135 can be a metal part such as copper, aluminum, steel, etc., or it can be a part made of conductive silicone, conductive plastic, etc.

One end of the connector 135 close to the chip is electrically connected to the conductive sheet 135a (equivalent to the ground terminal), wherein the conductive sheet 135a is arranged on the substrate 120 and is electrically connected to the memory of the chip 20. The memory needs to be grounded, and the connection method between the conductive sheet 135a and the memory is not limited. For example, the conductive sheet 135a can be connected to the memory through a conductive line, thereby connecting the connector 135 to the memory. The position of the conductive sheet 135a on the substrate 120 is not limited. In this embodiment, the conductive sheet 135a is arranged on the rear surface 120b of the chip, and is located on a different surface of the substrate from other terminals on the chip 20, ensuring that the conductive sheet 135a will not short-circuit with other terminals, ensuring good stability of the chip grounding, and improving the safety of chip use. The conductive sheet 135a (equivalent to the ground terminal) is a copper clad on the chip 20 made by electroplating and other processes.

The conductor 135cc is disposed on the ink cartridge body 50 and contacts other metal parts (equivalent to the grounding component) on the printer. Preferably, the conductor 135cc is disposed inside the ink cartridge body 50 to avoid contact with external objects and damage to the conductor 135cc, thereby ensuring that the grounding function of the connector 135 is stably realized. In this embodiment, the conductor 135cc is disposed inside the handle 30. The connecting body 135bb is used to connect the conductive sheet 135a and the conductor 135cc.

Specifically, the connecting body 135bb has a first portion 135b1, a second portion 135b2 and a connecting portion 135b3. The first portion 135b1 is used to connect to the conductive sheet 135a. The material of the first portion 135b1 and the connection method with the conductive sheet 135a are not limited. For example, the first portion 135b1 can be made of a conductive material with a certain hardness and can be connected to the conductive sheet 135a by soldering.

In some other embodiments, the connector 135 (equivalent to the conducting member) may not be provided with the conductive sheet 135a, that is, the first part 135b1 is directly connected to the memory (not shown in the figure) of the chip 20. The connection method of the first part 135b1 and the memory is not limited. For example, the first part 135b1 can be directly connected to the conductive wire connected to the memory through solder. The second part 135b2 is used to connect with the conductor 135cc. The connecting part 135b3 is used to connect the first part 135b1 and the second part 135b2. Preferably, the connecting part 135b3 is arranged in the corresponding groove on the ink cartridge body 50 to prevent external objects from damaging the connecting part 135b3 and affecting the conductive function of the connector 135, and it can also play a fixing role.

As shown in Figures 21 and 22, in this embodiment, the conductor 135cc is disposed in the handle 30. The handle 30 has a main body 301, an extension portion 302, a limiting portion 303, a clamping portion 304, and a connecting portion 305. The extension portion 302, the limiting portion 303, the clamping portion 304, and the connecting portion 305 are respectively disposed on the main body 301, and the manner in which they are disposed on the main body 301 is not limited, for example, they may be detachably connected, fixedly connected, etc.

One end of the extension part 302 in the X-axis direction is connected to the main body 301, and the other end is in contact with other metal parts (equivalent to the grounding component) on the printer. In this embodiment, the other end of the extension part 302 is in contact with the conductive wall plate 81 of the printer, so that the conductor 135cc is in contact with the conductive wall plate 81 to form an electrical connection. The extension part 302 plays a role in protecting the conductor 135cc to prevent it from being damaged, broken, or displaced.

Compared with the contact area of the chip grounding terminal on the contact pin in the existing ink cartridge installation part, the contact area between the conductive wall plate 81 and the connector 135 in this embodiment is larger, which can ensure stable and accurate electrical connection between the connector 135 and the grounding rail 80, ensure the stable implementation of the grounding function of the chip 20, prevent excessive current, and reduce the probability of electric shock danger caused by unstable grounding.

On the basis of the above embodiment, the extension portion 302 in the embodiment of the present application is further provided with a color identification portion 302a for indicating the ink color stored in the ink cartridge. The ink color indication method of the color identification portion 302a is not limited, for example, the ink color stored in the ink cartridge can be indicated by color, pattern, text and a combination thereof.

The limiting portion 303 cooperates with the limiting protrusion 502 provided on the ink cartridge to limit the movable range of the handle 30 in the X-axis direction. The position and shape of the limiting protrusion 502 on the ink cartridge body 50 are not limited. For example, the limiting protrusion 502 can be a cylinder, a cone, an irregular shape protrusion, etc. In this embodiment, the limiting protrusion 502 is a cylinder.

The engaging portion 304 cooperates with the fixing portion 90d provided on the mounting portion 90 to fix the ink cartridge 10 to the mounting portion 90 to prevent the ink cartridge 10 from being separated from the mounting portion 90. The connecting portion 305 is used to connect the handle 30 to the ink cartridge body 50. The connection method between the connecting portion 305 and the ink cartridge body 50 is not limited, for example, it can be a detachable connection, a fixed connection, etc. In some other embodiments, the handle 30 may not be provided with the connecting portion 305, and the main body 301 is directly connected to the ink cartridge body 50.

When the ink cartridge 10 is installed in the installation part, one end of the connector 135 is a conductive sheet 135a, which is connected to the memory on the ink cartridge chip 20 and receives the current output by the chip 20. The conductive sheet 135a passes the received current to the conductor 135cc through the connecting body 135bb. The other end of the connector 135 is a conductor 135cc, which is connected to other metal parts on the printer and passes the current received from the connecting body 135bb to other metal parts on the printer to realize the chip grounding function.

Specifically, the conductor 135cc is set through the handle 30, and the conductor 135cc is set through the main body 301, the extension part 302 and the connecting part 305 of the handle 30. Since the clamping part 304 set on the main body 301 of the handle cooperates with the fixing part 90d set on the mounting part 90, it is used to fix the ink cartridge 10 to the mounting part 90. The conductor 135cc is set through the handle 30 and is close to the clamping part 304 on the handle 30, which can ensure that the connector 135 is in stable and accurate contact with other metal parts on the printer, ensure that the grounding function of the chip 20 is stably realized, prevent excessive current, and reduce the probability of electric shock caused by unstable grounding. The stability of the chip grounding is ensured, the safety of chip use is improved, and the occurrence of the situation where the printing device cannot recognize the ink cartridge is reduced.

The third implementation of Example 1:

Figures 23 to 26 are schematic diagrams of the third embodiment of the first embodiment of the present application. The differences between this embodiment and the second embodiment are as follows: As shown in Figures 23 to 26, Figure 23 is a schematic diagram of the ink cartridge 10 being installed on the mounting portion 90, the grounding component has a grounding rail, the grounding rail has a conductive wall plate 81, and its conductive member 105 contacts the conductive wall plate 81 and transmits a grounding signal. A baffle 84 is provided in the +Z axis direction of the conductive wall plate 81.

Generally, the baffle 84 is made of plastic and non-conductive material. In the direction of the X-axis, the end of the baffle 84 is closer to the mounting portion 90 than the end of the conductive wall plate 81 (i.e., the end of the baffle 841 is located closer to the +Z axis and -X axis side than the conductive wall plate 81), so when the ink cartridge 10 is installed in the printing device, the conductive member 105 needs to pass over the baffle 841 before it can contact the conductive wall plate 81.

One end of the conductive member 105 in this embodiment is in contact with the ground terminal 135a on the chip 20, and the other end is in contact with the conductive wall plate 81 of the grounding component. The transmission path of the ground signal is: the memory of the chip 20, the ground terminal 135a, the conductive member 105, and the conductive wall plate 81 of the grounding component.

The handle 30 comprises: a main body 301, an extension 302, a snap-fitting portion 304, a first gap 308, and a second gap 309. A fixing portion 307 is also provided on the ink cartridge for fixing the conductive member 105. The extension 302 comprises a flat extension portion 3025, a first bending portion 3021, a second bending portion 3022, an abutting accommodating cavity 3023, and a fixing opening 3024. The purpose of providing the extension portion 302 is to fix the conductive member 105, to allow the conductive member 105 to pass over the baffle 84, and to allow the conductive member 105 to abut against the conductive wall plate 81. The flat extension portion 3025 extends in the +X axis direction in order to better allow the conductive member 105 to abut against the conductive wall plate 81.

The first bending portion 3021 extends from the flat portion 3025, and the first bending portion 3021 extends toward the +X axis (the direction where the conductive wall plate 81 is located) and the +Z axis direction (upward); the second bending portion 3022 extends from the first bending portion 3021, and the second bending portion 3022 extends toward the -X axis (away from the conductive wall plate 81/toward the direction where the box body is located) and the +Z axis direction (upward). This structural design is intended to guide the extension portion 302 and the conductive component 105 to cross the baffle 84 during the installation of the ink cartridge 10 into the printing device, and when the ink cartridge 10 is taken out of the printing device, the second bending portion 3022 can guide the deformation/compression of the handle 30 to facilitate the removal of the ink cartridge 10.

The abutment accommodating chamber 3023 is used to accommodate the abutment portion 1057 of the conducting member 105, and the abutment portion 1057 is used to make the conducting member 105 abut against the conductive wall plate 81. The abutment accommodating chamber 3023 is relatively a recessed portion, which can protect the abutment portion 1057 to a certain extent and reduce the possibility of it being damaged. The abutment accommodating chamber 3023 is arranged at the intersection of the first bending portion 3021 and the second bending portion 3022, so that the abutment portion 1057 is located at the position closest to the +X axis of the ink cartridge 10, so that the conducting member 105 abuts against the conductive wall plate 81.

Further, the fixed opening 3024 cooperates with the elastic part 1056, so that the conducting member 105 is firmly fixed on the ink cartridge 10, and prevents the conducting member 105 from being separated from the ink cartridge 10. The handle 30 is extended from the ink cartridge body 50, and has a certain elasticity, can be contracted toward the -X axis direction, and can be restored to the original position. The extension part 302 is located on the handle 30, so the extension part 302 also has a certain elasticity, can move toward the -X axis direction, and can allow the conducting member 105 to pass over the baffle 84, and can have a tendency to move toward the +X axis when the handle 30 is compressed, so that the abutting part 1057 has a compressive force, so that the abutting part 1057 can better abut against the conductive wall plate 81. The abutting part 1057 is located at the intersection of the first bending part 3021 and the second bending part 3022.

The conducting member 105 includes a first portion 1051a, a second portion 1051b, and a third portion 1051c. The first portion 1051a is fixed to the ink cartridge body 50, and specifically prevents the conducting member 105 from being separated from the ink cartridge body 50 through the cooperation of the through hole 1053 and the fixing portion 307. The through hole 1053 and the fixing portion 307 can be tightly fixed.

Optionally, after the through hole 1053 is matched with the fixing portion 307, the portion of the through hole 1053 protruding from the fixing portion 307 can be laid on the first portion 1051a by welding and hot melting to prevent the conductive member 105 from being separated from the ink cartridge body 50. The second portion 1051b is matched with the main body 301 of the handle 30, and a first gap 308 is provided on the -X axis direction side of the engaging portion 304 and the +X axis direction side of the main body 301, and the first gap 308 accommodates a portion of the second portion 1051b. The third portion 1051c is in conformity with the shape of the extension portion 302, so that the conductive member 105 can better abut against the conductive wall plate 81.

The third part 1051c has: an abutting portion 1057 and an elastic portion 1056. The abutting portion 1057 is disposed in the abutting accommodating cavity 3023. The elastic portion 1056 is an elastic sheet-like member extending from the conducting member 105, and can cooperate with the fixing opening 3024 to fix the conducting member 105 on the handle 30. The conducting member 105 has a first bending area AA extending toward the conductive wall plate 41 and a second bending area BB connected to the first bending area AA and extending toward the upward direction (+Z axis direction). The position where the conducting member 105 contacts the conductive wall plate 81 is located on the second bending area BB, that is, the abutting portion 1057 is located on the second bending area BB.

The first bending area AA is in the same direction as the first bending part 3021 of the extension part 302. The first bending area AA extends toward the +X axis (the direction of the conductive wall plate 81) and the +Z axis (upward). The second bending area BB is a part contained in the abutment accommodating cavity 3023, which is connected to the first bending area AA and extends toward the upward direction (+Z axis direction). This structure is conducive to the abutment between the conductive component 105 and the conductive wall plate 81. The abutment part 1057 is a protrusion on the second bending area BB. The abutment part 1057 can be an arc-shaped, spherical, linear, or dot-shaped protrusion. Preferably, the abutment part 1057 is a spherical protrusion (as shown in FIG. 26), which is convenient for abutment with the conductive wall plate 81 and can reduce the friction between the abutment part 1057 and the conductive wall plate 81 as the ink cartridge 10 slides with the mounting part 90, thereby ensuring that the ink cartridge 10 slides smoothly.

Since the handle 30 is elastic, it can shrink and return to its original state. The handle 30 is different in its natural state and in the state installed in the printing device. The conducting member 105 also has two states: an initial state and an abutting state. The conducting member 105 can switch between the initial state and the abutting state. The conducting member 105 is farther away from the ink cartridge body 50 in the initial state than in the abutting state. The abutting portion 1057 is farther away from the ink cartridge body 50 in the initial state than in the abutting state. After the ink cartridge 10 is installed in the printing device, the abutting portion 1057 of the conducting member 105 exerts a compressive force on the conductive wall plate 81, which can make the abutting portion 1057 better abut against the conductive wall plate 81.

It should be noted that the conducting member 105 is made of a conductive material, such as metal, conductive silicone, conductive plastic, etc. Optionally, the conducting member 105 is made of metal and bent into a structure as shown in Figures 23 to 25. The abutment portion 1057 can be made by hot pressing, and a spherical protrusion is hot pressed from the original flat metal plate surface; the elastic portion 1056 can be made by stamping, and one end of the elastic portion 1056 is punched off to form a hanging elastic portion 1056; the through hole 1053 can be made by stamping, and is punched into a through hole.

Fourth implementation of Example 1:

Fig. 27 is a schematic diagram of the fourth embodiment. The description of the ink cartridge in this embodiment is consistent with that of the first embodiment, and the chip used is the first variation of the chip or the third variation of the chip, which will not be described in detail here.

Embodiment 2

It should be noted that the installation method of the installation part and the ink cartridge in this embodiment is different from that in the first embodiment, and the installation part structure of the printer is also different. The installation part 90 of the second embodiment is fixed in the assembly bin, and the grounding component is arranged in the accommodating cavity.

The ink cartridge of the second embodiment can be adapted to several ink cartridges of the first embodiment. The second embodiment is different from the first embodiment in that: the second embodiment provides an antenna-type conductive component, and at least part of the cavity wall forming the installation cavity is configured as a grounding component, one end of the conductive component is electrically connected to the grounding terminal of the chip, and the other end is electrically connected to at least part of the top wall of the installation cavity, and the electrical connection point between the two is located above the chip.

On the basis of the above embodiment, the conductive sheet 135a in the conductive component can be eliminated in this embodiment, the connector 135 can be directly connected to the conductive wire by soldering, and the position of the positioning hole provided on the chip is also different from that in the above embodiment 1.

As shown in FIGS. 28 to 31 , in this embodiment, the chip 20 has a first hole 121 and a second hole 122. The first hole 121 and the second hole 122 are both through holes on the substrate 120, and both penetrate the front surface 120a and the rear surface 120b of the substrate 120. The first hole 121 is a semicircular concave portion formed from the left side 120c to the right side 120d, and the second hole 122 is a semicircular concave portion formed from the right side 120d to the left side 120c.

Correspondingly, the ink cartridge is provided with a chip mounting portion, which includes a first positioning column 601 and a second positioning column 602. The first positioning column 601 and the second positioning column 602 are respectively combined with the first hole 121 and the second hole 122 in a protruding manner, and then the chip 20 is fixed to the ink cartridge body 50 by a hot welding head. Such a configuration can prevent the chip 20 from being offset during the installation process or during use after the installation is completed.

As shown in Figures 30 and 31, when the consumable box 10 is installed on the mounting portion 90, one end of the connector 135 is connected to the ground terminal 135a of the memory 100/rear surface 120b set on the rear surface 120b of the substrate, and the connector 135 extends from the rear surface 120b of the substrate, and fits the box body 50 (ink cartridge body 50) along the direction of the box body 50 away from the chip 20 until it is close to the end side of the connector 135. The connector 135 bends in the direction away from the surface of the box body 50, thereby connecting with the metal part 96 (equivalent to the grounding component of Example 1) on the printing device. The beneficial effects of this design are: the chip grounding has good stability and the safety of chip use is improved.

When the ink cartridge 10 is mounted on the mounting portion 90, the connector 135 connected to the memory 100 is attached (or abutted) along the rear surface 120b of the chip 20 and extends to the top surface of the ink cartridge 10, and then extends from the upper end of the chip 20 and the top surface of the ink cartridge 10 along the top surface of the ink cartridge 10, and enters the gap of the mounting portion, and the end of the connector 135 is folded into a right angle. The end 135e of the connector 135 (the end away from the ink cartridge body) abuts against the metal member 96 (equivalent to the grounding member of the first embodiment).

The connecting member 135 (same as the conducting member in the first embodiment) is bent in a direction away from the surface of the ink cartridge body 50 and toward the metal member 96 of the printer (the cavity containing the ink cartridge 10). The metal member 96 is the first side wall 90c of the mounting portion in the embodiment of the present application, that is, at least part of the cavity wall forming the accommodating cavity is configured as a grounding member, and the electrical connection position between the grounding member and the conducting member is located above the chip. In this way, the stability of the chip grounding is good, which improves the safety of the chip.

One end of the connector 135 is connected to the rear surface 120 b of the substrate 120 , and the other end is connected to the metal component 96 of the printing device. The metal component 96 of the printing device is not limited and can be any metal on the printing device that can be contacted by the connector 135 .

Embodiment three:

It should be noted that the installation method of the installation part and the ink cartridge in this embodiment is different from that in the first embodiment, and the installation part structure of the printer is also different. The installation part 90 of the second embodiment is fixed in the assembly compartment, and the grounding component is arranged in the accommodating cavity.

This embodiment provides another antenna-type conductive component, and at least part of the cavity wall forming the installation cavity is configured as a grounding component, one end of the conductive component is electrically connected to the ground terminal of the chip, and the other end is electrically connected to at least part of the cavity wall of the installation cavity.

The first implementation method of the third embodiment:

As shown in FIG32 , the front surface 120a of the chip 20 is provided with a first terminal 131 to a fourth terminal 134, and the position arrangement of their respective contact portions C, the memory 100, the connector 135, and the second positioning hole 122 of the substrate are the same as those in the second embodiment and are not described in detail here.

The connector 135 (equivalent to the conductive member in the first embodiment) connected to the memory 100 is attached (or abutted) along the rear surface 120b of the chip 20 and extends to the top surface of the ink cartridge 10, and then extends from the upper end of the chip 20 and the top surface of the ink cartridge 10 along the top surface of the ink cartridge 10 to enter the gap of the mounting portion. The end 135e (the end away from the ink cartridge body) of the connector 135 abuts against the grounding component. The extended portion of the connecting strip 135 (which can be called the connector 135) (equivalent to the conductive member in the first embodiment) is bent, folded in a direction away from the surface of the box body 50, toward the metal part (equivalent to the grounding part in the first embodiment) of the printing device (the cavity that accommodates the ink cartridge 10), thereby achieving electrical connection with the metal part of the printing device.

Second implementation of Example 3:

In a second embodiment, another antenna-type conductive component is provided in this embodiment, and at least part of the cavity wall forming the installation cavity is configured as a grounding component, one end of the conductive component is electrically connected to the ground terminal of the chip, and the other end is electrically connected to at least part of the cavity wall of the installation cavity.

The installation method of the mounting portion and the ink cartridge in this embodiment is different from that in the first embodiment, and the structure of the mounting portion of the printer is also different, so the direction represented by the three-dimensional coordinate system in this embodiment is also different from that in the first embodiment. The mounting portion 90 of the second embodiment is fixed in the assembly bin, and the grounding component is arranged in the accommodating cavity.

As shown in FIG. 33 , the printer in this embodiment includes: a printing unit 4 and a base 5 . The base 5 includes: a bracket and one or more mounting parts 90 .

Furthermore, one mounting portion 90 can carry one ink cartridge 10. When the number of mounting portions 90 is 4 (as shown in FIG. 33 ), four ink cartridges 10 can store four different colors of ink, such as black, yellow, blue, and red. For another example, when the base 5 can carry six ink cartridges 10, the number of mounting portions 90 is 6, and the six ink cartridges 10 store black, yellow, blue, red, light blue, and light red inks, respectively. Furthermore, multiple mounting portions 90 can contain ink of the same color (e.g., black).

The ink cartridge 10 is first installed in the tray 97 along the first direction D1, and then the combination of the ink cartridge 10 and the tray 97 is installed in the mounting portion 90 along the second direction D2. When the printer is printing, the base 5 provides ink for the printing work of the printing unit 4 to ensure the normal printing work of the printing unit 4. When the printer is placed in a natural state, the printing unit 4 is directly above the base 5.

In the three-dimensional right-angle XYZ axis coordinate system shown in FIG. 33 , the X axis, Y axis, and Z axis are perpendicular to each other. When the printer is placed in a natural state, the direction of gravity is the +Z direction, the installation direction D2 (second direction D2) of the ink cartridge 10 installed in the installation portion 90 is the +Y direction, and the arrangement direction of the installation portion 90 is the +X direction. The first direction D1 is the +Z direction. When the ink cartridge 10 needs to be installed in the installation portion 90, the ink cartridge 10 is first installed on the tray 97 along the first direction D1; then the combination of the ink cartridge 10 and the tray 97 is installed in the installation portion 90 along the installation direction D2.

As shown in Figure 34, this structure is the part installed in the +Y direction of the base 5. When the ink cartridge 10 (or it can be a combination) is installed in the mounting portion 90 along the mounting direction D2, the front end side of the ink cartridge 10 in the +Y direction contacts the structure shown in Figure 34, thereby ensuring that the ink cartridge 10 (or it can be a combination) is combined with the mounting portion 90 in place.

The internal structure of the mounting portion 90 includes a fixing frame, on which are disposed a stylus assembly 91, an ink supply portion 92 (ink injection tube), columnar positioning portions 93f, 93s and a locking portion 94. The locking portion 94 is a rod-shaped component that can be reset and swung, that is, the locking portion 94 is configured as a conductive swing rod of the present application, and the rod-shaped component is provided with a protrusion extending in the -Z axial direction at the movable end, and the protrusion is used to cooperate with the groove at the bottom of the tray 97 to fix the combination of the ink cartridge 10 and the tray 97.

The stylus assembly 91 can be electrically connected to the chip on the ink cartridge 10 when the assembly is mounted to the mounting portion 90. The stylus assembly 91 includes a plurality of stylus pins (not shown in the figure) made of elastic conductive steel sheets. The stylus assembly 91 is tiltedly arranged in the mounting portion 90. The specific structure of the stylus assembly 91 is not described in detail. The structure can be referred to in Figure 4. Specifically, the above-mentioned assembly is installed or removed along the +Y and -Y directions in the figure. The assembly is physically engaged with the mounting portion 90 through the housing, and is electrically connected to the stylus assembly 91 through the chip on the ink cartridge.

As shown in Figures 35-38, the ink cartridge 10 includes: a chip 20, a connector 60, an ink supply head 40 and an ink bag 10a, wherein the chip 20 is arranged on the front end side of the installation direction D2 of the ink cartridge 10, the connector 60 is configured as a conductive component, the connector 60 is made of conductive material, and a part of the connector 60 is connected to the chip 20, and the other part is connected to the grounding component.

An ink outlet 41 is provided on the +Y axis side of the ink supply head 40. Ink is stored in the ink bag 10a. The ink outlet 41 is connected to the internal liquid of the ink bag 10a. The ink reaches the ink filling tube 92 through the ink outlet 41, and then the ink filling tube 92 can supply ink to the print head, so that the print head can be used to perform printing.

After adopting the above technical solution, the ground signal is transmitted to the chip 20 through the metal parts and the conductive components, which improves the stability and reduces the situation where the grounding cannot be connected or the grounding is unstable. No ground terminal is set on the substrate. By using the connector, the grounding stability of the chip is improved to prevent excessive current, and the probability of the ground terminal on the chip failing to stably contact the contact pin on the printer to cause electric shock is reduced, which helps to improve the safety of the chip and reduce the situation where the printing device cannot recognize the ink cartridge.

In the above scheme, the metal part of the mounting portion 90 (equivalent to the grounding component of the first embodiment) can be the outer frame of the mounting portion 90 (the outer frame in the +Z axis, -Z axis, +X axis, -X axis, +Y axis directions) or a part of the outer frame. For the safety of the user, the metal parts of the mounting portion 90 are all grounded, and the grounding signals between the printers are all connected. Preferably, in this embodiment, the other part of the connecting member 60 (equivalent to the conducting member of the first embodiment) is connected to a part of the metal part 96 in the -Z axis direction of the mounting portion 90, that is, at least part of the cavity wall of the accommodating cavity forms a grounding component. As shown in Figure 33, the metal part 96 is arranged in the -Z axis direction of the base 5, and the metal part 96 (equivalent to the grounding component of the first embodiment) is connected to the grounding signal of the printer 1.

As shown in Figures 35 and 36, the chip 20 provided in this embodiment has a memory 100, a substrate 120, and a plurality of terminals 130. The substrate 120 has a front surface 120a, a rear surface 120b, a left side surface 120c, a right side surface 120d, a top surface 120e, and a bottom surface 120f, wherein the front surface 120a is arranged opposite to the rear surface 120b; the left side surface 120c is arranged opposite to the right side surface 120d; and the top surface 120e and the bottom surface 120f are arranged opposite to each other.

Furthermore, the chip 20 has a first hole 121, a second hole 122, a third hole 123 and a fourth hole 124. The first hole 121, the second hole 122, the third hole 123 and the fourth hole 124 are all through holes on the substrate 120, and all penetrate the front surface 120a and the rear surface 120b of the substrate 120.

The first hole 121 is a recessed portion formed from the top surface 120e to the bottom surface 120f, the second hole 122 is a recessed portion formed from the bottom surface 120f to the top surface 120e, the third hole 123 is a recessed portion formed from the left side surface 120c to the right side surface 120d, and the fourth hole 124 is a recessed portion formed from the right side surface 120d to the left side surface 120c.

In this way, a chip mounting portion is provided on the ink cartridge 10 capable of mounting the chip 20 of this embodiment, and the chip mounting portion includes a plurality of positioning columns, which are respectively combined with the first hole 121, the second hole 122, the third hole 123 and the fourth hole 124 in a protruding manner, and then the chip 20 is fixed to the ink supply head 40 by means of a hot welding head, so as to prevent the chip 20 from being shifted in position along the Y-axis or Z-axis direction during the installation process or the use process after the installation is completed.

Similar to the first embodiment described above, the terminals 131 - 134 arranged on the front surface in this embodiment are all communication terminals, and the purpose and layout of each communication terminal on the front surface are the same as those in the first embodiment, which will not be repeated here.

The connector 60 (equivalent to the conducting member of the first embodiment) and the memory 100 may also be connected via the fifth terminal/additional terminal 135a (equivalent to the ground terminal of the first embodiment) and its wire. It is understandable that the fifth terminal 135a may not be provided in this embodiment, but the connector 60 is directly connected to the memory 100. Preferably, the fifth terminal 135a is used to make the connection between the connector 60 and the memory 100 more effective and the contact more stable.

Further, the conducting member and the fifth terminal/additional terminal 135a can be connected by soldering or fixing. Each terminal 130 has a contact portion, which is respectively the first contact portion-the fourth contact portion. The contact portion is the most likely contact area of the contact pin on the terminal 130 when the ink cartridge is installed on the printer.

In the embodiment of the present application, the connector 60 serves as a conducting component, and the connector 60 is made of a conductive material. The ground signal of the printer is connected to the memory through the conducting component and the fifth terminal/additional terminal (equivalent to the ground terminal) so that the chip of the ink cartridge and the grounding component are grounded together.

As shown in Figures 37 to 42, the connector 60 includes a first portion 60a and a second portion 60b, wherein the first portion 60a is used to connect the second portion 60b and the fifth terminal/additional terminal 135a of the chip 20; and the second portion 60b is used to connect the metal member 96 and the first portion 60a.

The chip 20 is connected to the first part 60a. When the ink cartridge is installed on the mounting portion 90, the communication terminals of the chip 20 are respectively connected to the first contact pin 911 to the fourth contact pin 914 on the contact pin assembly 52. The shapes of the first part 60a and the second part 60b are not limited. They can be set to regular shapes, such as rectangles, or to zigzag or other irregular shapes. In addition, the first part 60a can be integrally formed or can be formed by splicing several sections of metal sheets.

Furthermore, the connector 60 may also be an integrated structure without the first part 60a and the second part 60b. When the conductive member includes the first part 60a and the second part 60b, the structure of the first part 60a is simplified, and the second part 60b can be manufactured into a more complex structure.

For example, the second portion 60b can also be used as the handle 30 of the ink cartridge, and when the ink cartridge is installed on the tray 97, it plays the role of a handle during the installation and removal process, making it convenient for the user to install and remove the ink cartridge. This arrangement can not only complete the transmission of the ground signal, but also simplify the structure of the ink cartridge (reducing the production, manufacturing, and assembly of the parts of the handle). Therefore, this structure can reduce the number of parts, simplify the partial structure of the ink cartridge, and reduce costs.

Furthermore, the first part 60a of the connector 60 has a first connecting portion 60aa and a second connecting portion 60ab. The first connecting portion 60aa is used to connect to the fifth terminal or the additional terminal 135 of the chip 20; and the second connecting portion 60ab is used to connect to the second part 60b.

The second portion 60 b includes a first connection portion 60 ba and a second connection portion 60 bb, wherein the second connection portion 60 bb is used to connect with the second connection portion 60 ab, and the first connection portion 60 ba is used to abut against the metal member 96 .

Specifically, the first connection portion 60ba abuts against the surface of the +Z axis of the metal member 96 to complete the transmission of the ground signal. The first connection portion 60ba is not necessarily at the end of the second portion 60b; as shown in Figures 41-42, the first connection portion 60ba is set in the middle of the second portion 60b. The first connection portion 60ba can be a combination of one or more positions.

As shown in FIG. 41 , the first connection portion 60ba can be in three different positions. Because the second portion 60b needs to abut the metal member 96 and also needs to act as a handle, the first connection portion 60ba is on the -Z-axis side of the second portion 60b in the Z-axis direction. In the Z-axis direction, the first connection portion 60ba is located on the -Z-axis side of the second connection portion 60bb; the second portion 60b is located on the -Z-axis side of the first portion 60a; and the first portion 60a is located on the -Z-axis side of the chip 20. That is, the portion abutting against the metal member 96 is located at the uppermost position.

In the Y-axis direction, the first connection portion 60ba is located on the -Y-axis direction side of the second connection portion 60bb; the second portion 60b is located on the -Y-axis direction side of the first portion 60a; and the first portion 60a is located on the -Y-axis direction side of the chip 20. That is, the first connection portion 60ba is located on the -Z-axis and -Y-axis direction sides of the second connection portion 60bb; the second portion 60b is located on the -Z-axis and -Y-axis direction sides of the first portion 60a; and the first portion 60a is located on the -Z-axis and -Y-axis direction sides of the chip 20.

It should be noted that the metal part 96 that the second part 60b contacts can be any conductive metal part of the printer. Preferably, along the Z-axis direction, the metal part 96 that the second part 60b contacts is located at the top of the ink cartridge 10.

In addition, referring to Figures 34 and 37, when the ink cartridge is installed on the mounting portion 90, the columnar positioning portions 53f and 53s cooperate with the positioning holes 97a and 97b on the tray 97 and the holes 42a and 42b on the ink cartridge to limit the position of the assembly on the mounting portion; the ink injection tube 92 (equivalent to the ink supply portion 92 of Example 1) matches the ink outlet 41 to provide ink for the printer to print; the stylus assembly 91 contacts the chip 20 to provide chip signal transmission.

The protrusion on the locking portion 94 is used to cooperate with the groove at the bottom of the tray 97 to fix the combination of the ink cartridge and the tray 97. The connecting member 60 contacts the metal member 96 to transmit the ground signal. The connecting member 60 acts as a handle during the process of installing the ink cartridge to the tray 97, which is convenient for users to operate the installation and removal of the ink cartridge.

It should be noted that the number and shape of the positioning holes 97a/97b on the tray 97 and the holes 42a/42b on the ink cartridge are not limited. For example, one or more positioning holes may be provided, and the shapes may be circular, square or other irregular shapes, as long as they can be stably matched with the printer and stably installed in the ink cartridge.

Further, referring to Figures 37 to 40, the ink cartridge in this embodiment has an ink supply head 40 and an ink bag 10a storing ink therein. The chip 20 and the connector 60 are both disposed on the ink supply head 40. An ink outlet 41 is disposed on the +X side of the ink supply head 40, and the ink outlet 41 is connected to the ink bag 10a through an internal lead-out flow channel thereof, and is used to supply the ink stored in the ink bag 10a to the printer via the ink outlet 41.

Referring to Fig. 40, an axial hole is provided on the +Z axis side of the ink supply head 40, and the axis of the second part 60b is installed in cooperation with the axial hole. A support member 102 is also provided on the +Z axis side of the ink supply head 40, which is located on the +Z axis side of the second part 60b and the -Y axis side of the axial hole, and supports at least a portion of the second part 60b.

Specifically, in this embodiment, the support member 102 is a protrusion extending from the upper surface of the ink supply head 40 in the +Z axis direction, and along the +Z axis direction, the support member 102 is higher than the above-mentioned axis. When the ink cartridge is installed, at least part of the second part 60b is in contact with the support member 102 and is located on the +Z axis side of the support member 102.

Therefore, in the installed state, the second part 60b is inclined toward the -Y axis side and the -Z axis side due to the action of the support member 102, and the -Z axis end of the second part 60b contacts the metal part 96 above the ink cartridge and realizes electrical connection, so that it can be achieved that: the first connecting part 60ba is located on the -Z axis and -Y axis direction side of the second connecting part 60bb; the second part 60b is located on the -Z axis and -Y axis direction side of the first part 60a.

Such a setting not only reduces the risk of electric shock caused by unstable grounding, but also makes the chip grounding stable, improving the safety of chip use. At the same time, it is also convenient for users to operate and remove ink cartridges.

It should be noted that the number and shape of the support members 102 are not limited. Specifically, the support members 102 can be set to one, two or more, and can be set to a cuboid, a cylinder or a triangular prism or other regular or irregular shapes, as long as they can support the second part 60b and enable it to achieve stable contact with the metal member 96.

Preferably, along the X-axis direction, the contact area between the second portion 60b and the metal member 96 is closer to the left side 120c of the chip substrate 120 than the right side 120d of the chip substrate 120. Preferably, the contact area between the second portion 60b and the metal member 96 may not be set on the first connecting portion 60ba as shown in FIG. 41, but may be set within the region range of the first region R1.

As shown in FIG41 , the portion where the second portion 60b is connected to the metal member 96 is the third connection portion 60bc. The third connection portion 60bc is located at the first region R1, and in the X-axis direction, the second portion 60b is tilted (this tilting manner can be achieved by different heights of the plurality of support members 102), and the third connection portion 60bc is located at the +Z-axis end of the second portion.

It should be noted that, during the process of installing the ink cartridge 10 into the printing device, the connector 60 (conducting member) contacts the grounding component first, and the chip 20 contacts the contact pin assembly 91 later.

The third implementation method of the third embodiment:

In the third embodiment, based on the above-mentioned embodiment 2, this embodiment provides a new conductive component, one end of which is electrically connected to the ground terminal of the chip, and the other end is electrically connected to at least part of the cavity wall of the mounting cavity, and the electrical connection position between the two is located above the chip.

As shown in FIGS. 43 and 44 , the chip provided in this embodiment is different from the above-mentioned embodiment 3 in that: a recess 21 is provided in the chip 20. The function of the recess 21 is to avoid the fifth contact pin 915 and prevent the fifth contact pin 915 from abutting or contacting the chip 20; that is, when the ink cartridge 10 is installed on the installation part of the printer, a part of the fifth contact pin 915 is located in the recess 21, and the fifth contact pin 915 will not abut or contact the chip 20.

It should be noted that the chip 20 may not have the recess 21, as long as there is no terminal/contact portion that can be connected to the fifth contact pin 915 in the X-axis direction of the chip. Even if the chip 20 is in contact with the fifth contact pin 915, no electrical connection will be generated between the two, and no ground signal will be transmitted.

As shown in FIGS. 45 to 51 , the ink cartridge 10 includes: a chip 20, a connector 70 (equivalent to the conductive member of the first embodiment), an ink supply head (also referred to as a base) 40 and an ink bag 10a; the chip 20 is arranged at the front end side of the installation direction D2 of the ink cartridge 10; the connector 70 is configured as a conductive member, and its material is a conductive material, wherein a part of the connector 70 is connected to the chip 20, and another part is connected to the metal member 96 (equivalent to the grounding member of the first embodiment) of the mounting portion 90. For example, the connector 70 is connected to the lower side 96a of the metal member 96 in the +Z axis direction, that is, the connector 70 is connected to the lower side 96a of the metal member 96 (equivalent to the grounding member of the first embodiment) facing the mounting portion 90.

The grounding signal between the chip 20 and the printer is transmitted through the connector 70 and the metal member 96. After adopting the above technical solution, the grounding signal is transmitted to the chip 20 through the metal member 96 and the connector 70, which improves the stability and reduces the situation of being unable to ground or unstable grounding.

Further, in this embodiment, the first terminal 131-the fourth terminal 134 are arranged on the front surface 120a of the chip 20, and the fifth terminal 135 is arranged on the rear surface 120b of the chip 20. A plurality of terminals 130 (the first terminal 131-the fifth terminal 135) are arranged in the first region R1 of the -X axis of the chip 20. The first region R1 is located on the -X axis side of the chip, so that the terminals on the chip 20 are compactly arranged, and the fifth terminal 135 for transmitting the ground signal and the communication terminal (the first terminal 131-the fourth terminal 134) for transmitting the signal with a high level are distributed on different surfaces of the chip 20, so that the possibility of short circuit between the two is reduced and electromagnetic interference between them is avoided.

The difference from the third embodiment is that, as shown in Figures 45 and 46, the connector 70 provided in this embodiment is an integrally formed component. Its manufacturing material can be a metal profile made of low carbon steel or high carbon steel, and the surface can be nickel-plated or chrome-plated for rust prevention; its raw material can also be a metal profile made of stainless steel.

The cross section of the connector 70 may be circular, oval, rectangular, square, trapezoidal, etc. The production process may be hot forming or cold forming. For example, a metal wire with a diameter of 0.6 mm and a surface nickel-plated 82B high carbon steel is produced by a spring machine through a hot deformation process to produce a conductive component as shown in FIG. 45. The present embodiment does not limit the raw materials, profiles, production processes, etc. of the conductive component, as long as the stable transmission of the ground signal can be guaranteed.

For example, if the cross section of the profile is circular, it can be a metal wire with a diameter of 0.3-2.5 mm. Preferably, the diameter of the conductive member is a metal wire with a diameter of 0.5-1.0 mm, and the elasticity and stability of the shape of the metal wire are required. If the cross-sectional diameter of the metal wire is small, it may not be able to maintain the original shape stably, and it may not be able to meet the requirement that the ink cartridge 10 can still maintain the original shape after multiple installations, thereby affecting the smooth transmission of the ground signal. If the diameter of the metal wire is large, it may cause jamming during the installation or removal of the ink cartridge 10.

If the metal wire is non-circular, a metal profile with a width of 0.3-2.5 mm can be selected, and preferably a metal profile with a width of 0.5-1.0 mm can be selected for the conductive member. If the diameter of the profile is circular, elliptical, etc., and the main surface is an arc shape, a contact plane can be ground at the position of the fourth part 704 (such as the position where the dotted line in Figure 45 is located) so that the part connected to the lower side 96a of the +Z axis of the metal part 96 becomes the first contact part 70a.

The contact plane 70a' can be ground with the original first contact part 70a as the center. Specifically, a small plane can be ground on a grinding machine (such as the position of the dotted line in Figure 45), so that the part that plays a role in connecting with the metal part 96 becomes the first contact part 70a. Because the contact between the connecting member 70 and the metal part 96 is a plane contact rather than a point contact, it can reduce the impact of the vibration generated during the operation of the printer and some external vibrations on the contact stability between the connecting member 70 (equivalent to the conductive component of the first embodiment) and the metal part 96, which is beneficial to improve the contact stability and the stable transmission of the ground signal. The contact plane 70a' can also be a small plane extruded on the basis of the original first contact part 70a, which is called the first contact part 70a.

The connector 70 in this embodiment includes: a first contact portion 70a, a second contact portion 70b, a semi-closed loop 70c, a first bending space 70d, a second bending space 70e, a third bending space 70f, and a fourth bending space 70g. According to the bending conditions of the profile, the connector 70 is divided into a first portion 701, a second portion 702, a third portion 703, a fourth portion 704, a fifth portion 705, a sixth portion 706, a seventh portion 707, an eighth portion 708, a ninth portion 709, a tenth portion 710, and an eleventh portion 711.

Among them, the second part 702, the fourth part 704, the sixth part 706, the seventh part 707, the eighth part 708, and the tenth part 710 are bending areas. The first contact portion 70a is located on the fourth part 704. When viewed in the Z-axis direction, the first contact portion 70a is located at the end position of the connecting member 70 in the -Z direction, and abuts against the lower surface 96a of the +Z axis of the metal member 96. The first contact portion 70a is located in the -Z-axis direction of the second contact portion 70b.

The fourth portion 704 is located at the -Z axis side compared to other portions of the connector 70. The semi-enclosed loop 70c is located at the -Y axis side of the connector 70, and the semi-enclosed loop 70c is a space formed by the first portion 701, the second portion 702, the third portion 703, the fourth portion 704, and the fifth portion 705. The inclination directions of the third portion 703 and the fifth portion 705 are different. When viewed along the Y axis direction, the third portion 703 is inclined toward the -Z axis direction, and the fifth portion 705 is inclined toward the +Z axis direction.

That is, the third portion 703 is inclined toward the +Y axis and the -Z axis direction, and the fifth portion 705 is inclined toward the +Y axis and the +Z axis direction. The third portion 703, the fourth portion 704, and the fifth portion 705 together form a peak shape, and the fourth portion 704 is located at the -Z axis side. At least a portion of the fifth portion 705 is located at the -Z axis side of the sixth portion 706 to the eleventh portion 711.

When the ink cartridge 10 is installed in the installation part 90, the fifth part 705 will first contact the metal part 96 (if a mounting part protection component is provided in the -Y axis direction of the metal part 96 in the printer, the fifth part 705 will first contact the mounting part protection component, and the fifth part 705 will contact the metal part 96 after passing the mounting part protection component). As the ink cartridge 10 is continuously installed along the installation direction D2, the -X axis side of the connecting part 70 and the semi-enclosed ring 70c will be compressed and deformed to a certain extent, until the connecting part 70 enters the installation part 90 as a whole, and the first contact part 70a abuts against the lower surface 96a of the metal part 96. In the above installation process, the fifth part 705 plays the role of guiding the connecting part 70 to be installed in the installation part 90 and guiding the deformation of the connecting part 70, and finally completing the abutment of the first contact part 70a with the metal part 96.

When the ink cartridge 10 is about to be separated from the mounting portion 90 and the chip 20 is about to be separated from the contact pin assembly 91 of the printer, the first contact portion 70a will not be separated from the metal part 96. The first contact portion 70a will be separated from the metal part 96 only when the ink cartridge 10 is about to be completely separated from the mounting portion 90.

Furthermore, before the first contact portion 70a disengages from the metal part 96, as the ink cartridge 10 is continuously moved out in a direction opposite to the installation direction D2, the third portion 703 will play a guiding and buffering role, thereby preventing the connecting member 70 from being stuck on the protective component on the metal part 96 during the process of the ink cartridge 10 disengaging from the installation portion 90, and finally the ink cartridge 10 can be smoothly removed.

With such a configuration, when the ink cartridge 10 is separated from the mounting portion 90, the connector 70 will return to its initial state under the action of its own elastic force. The connector 70 has an initial state (when the connector 70 has not yet been mounted on the mounting portion 90) and an abutting state (when the connector 70 is mounted on the mounting portion 90), which is conducive to better contact between the connector 70 and the metal member 96, thereby reducing the occurrence of unstable contact.

The seventh part 707 and the eighth part 708 are both bent into a U-shaped structure with the opening facing the +Z axis direction, which can be joined together with the first edge 403 and the second edge 404 on the ink supply head 40 to play the role of fixing the conductive component, so that the connecting part 70 can withstand the pressure of the metal part 96 on the -Y axis side of the conductive component 70 and the pressure of the chip 20 on the second contact part 70b, and can ensure the elastic restoring force of the connecting part 70, and can ensure that the connecting part 70 switches between the initial state and the abutment state.

A third bending space 70f of a U-shaped structure with an opening toward the −Z axis direction is formed between the seventh portion 707 and the eighth portion 708. Some movable buckles may be provided on the ink supply head 40, and the movable buckles are engaged with the third bending space 70f to prevent the connector 70 from being separated from the ink supply head 40.

The second contact portion 70b is formed on the tenth portion 710, and the second contact portion 70b abuts against the fifth terminal 135 of the chip 20, and the chip 20 applies a certain pressure to the second contact portion 70b, so that the second contact portion 70b is better in contact with the fifth terminal 135. The tenth portion 710 can grind a small plane at the tip of the bend to form the second contact portion, so that the connector 70 and the chip 20 are in more stable contact.

As shown in Figures 43 to 46, the connector 70 is not offset in the X-axis direction, that is, when the ink cartridge 10 is observed along the -Y-axis direction, the projection of the connector 70 is on the same line perpendicular to the X-axis. Therefore, the projection of the first contact portion 70a on the chip 20 is located on the fifth terminal 135, the projection of the first contact portion 70a on the chip 20 is located in the first region R1, and the projection of the first contact portion 70a on the chip 20 is located on the -X-axis position side of the chip 20. The presence of the eleventh portion 711 can prevent the connector 70 from scratching the fifth terminal 135 during the manufacturing process, thereby avoiding damage to the fifth terminal 135.

It should be noted that, as shown in FIG. 47 and FIG. 48 , the ink cartridge 10 further includes a chip mounting portion 201. The chip mounting portion 201 is used to carry the chip 20. The chip 20 is fixed to the ink cartridge 10 through the chip mounting portion 201. The chip mounting portion 201 has a through groove 2011, a receiving portion 2012, a plane 2013, a positioning column 2014, and a fixing portion 2015.

The plane 2013 is in contact with the rear surface 120b of the chip 20 and is used to position the chip 20. The receiving portion 2012 is used to receive the memory 100. The positioning column 2014 matches the first hole to the fourth hole of the chip 20, thereby ensuring that the chip 20 is fixed on the chip mounting portion 201. The connector 70 passes through the through slot 2011 and abuts against the fifth terminal 135 of the chip 20. As shown in FIG. 31 , all or at least a part of the ninth portion 709, the tenth portion 710, and the eleventh portion 711 of the connector 70 are received in the through slot 2011.

The fixing portion 2015 is a protrusion provided on the chip mounting portion 201, which matches the fixing groove 451 on the ink supply head 40 and is used to fix the chip mounting portion 201. Some buckles can be provided on the fixing portion 2015, and are engaged with the fixing groove 451 through the buckles. Such a setting can reduce the chip mounting portion 201 from being separated from the ink supply head 40 under the elastic force of the connecting member 70.

The ink supply head 40 has an upper surface 40a on the -Z axis side, a protrusion and a bearing portion 45. The protrusion is located on the -Y axis side of the upper surface 40a. The protrusion may have only the first protrusion 43 (as shown in FIG. 50 ), or may have the first protrusion 43 and the second protrusion 44 (as shown in FIG. 50 ). When the protrusion includes the first protrusion 43 and the second protrusion 44, the first protrusion 43 and the second protrusion 44 may serve as a gripping portion for a user who installs the ink cartridge 10 to the tray 97 along the installation direction D1 or takes out the ink cartridge 10 in a direction opposite to the installation direction D1. The user can move the ink cartridge 10 by gripping the sides of the first protrusion 43 and the second protrusion 44, which is conducive to taking out and installing the ink cartridge 10.

The ink supply head 40 further includes: a first protrusion 401, a second protrusion 402, a first ridge 403, a second ridge 404, and a fixing groove 451. The fixing groove 451 is used to fix the chip mounting portion 201. When the connecting member 70 is installed on the ink supply head 40, the first protrusion 401 is located in the semi-enclosed ring 70c of the connecting member 70, thereby reducing the occurrence of the situation where the connecting member 70 is separated from the ink supply head 40.

The second protrusion 402 is located in the first bending space 70d of the connecting member 70, so as to reduce the occurrence of the connecting member 70 being separated from the ink supply head 40; the first ridge 403 cooperates with the seventh portion 707, and the two may be in an interference fit state, so as to reduce the occurrence of the connecting member 70 being separated from the ink supply head 40; the second ridge 404 cooperates with the eighth portion 708, and the two may be in an interference fit state, so as to reduce the occurrence of the connecting member 70 being separated from the ink supply head 40. Some movable buckles may be provided on the ink supply head 40, and the movable buckles are engaged with the third bending space 70f, so as to prevent the connecting member 70 from being separated from the ink supply head 40.

The first protrusion 401 is provided with a slope 401a on the -Z axis side, the second protrusion 402 is provided with a slope 402a on the -Z axis side, the first edge 403 is provided with a slope 403a on the -Z axis side, and the second edge 404 is provided with a slope 404a on the -Z axis side. The above slopes serve as a guide when installing the connecting part 70 onto the ink supply head 40.

Further, as shown in FIG. 52 , the ink supply head 40 of the ink cartridge 10 in this embodiment is provided with a widening member 46 at the +X axis side and the -X axis side, which increases the width of the ink cartridge 10 in the X axis direction, and is conducive to widening the width of the ink bag 10a, and increasing the ink capacity of the ink bag 10a. At the same time, it can be understood that the tray 97 will also be widened in the X axis direction. It should be noted that in this embodiment, when the ink cartridge 10 is installed in the printing device, the connector 60 (conducting member) contacts the grounding component first, and the chip 20 contacts the contact pin assembly 91 later.

Fourth implementation of Example 3:

In the fourth embodiment, this embodiment provides a ground wire type conductive component based on the above embodiment, wherein one end of the conductive component is electrically connected to the ground terminal of the chip, and the other end extends downward and is electrically connected to the conductive rocker arm, and the electrical connection position of the two is located below the chip, and is further connected to the grounding component through the conductive rocker arm.

Specifically, as shown in Figures 53 and 54, the ink cartridge body 50 also includes a bottom shell 51 (equivalent to the ink supply head 40 in embodiments two and three). In the installation direction D2 (+Y-axis direction), at least a portion of the connecting member 70 is arranged on the front end side of the front surface 51a, and a space Q is formed between the connecting member 70 (equivalent to the conductive member) and the front surface 51a, and the space Q can accommodate a portion of the mounting portion 90; at least a portion of the connecting member 70 is arranged below the bottom surface 51b of the ink cartridge 10.

Further, as shown in FIG. 55 , the connector 70 is configured as a first conductive sheet, and a conductive swing rod is provided at the bottom of the accommodating cavity, wherein the conductive swing rod is located at the bottom of the ink cartridge body and can limit the ink cartridge body. In this embodiment, the locking portion 94 is a rod-shaped component that can be reset and swung, that is, the locking portion 94 is configured as a conductive swing rod, and the upper surface of the locking portion 94 can be electrically connected to the first conductive sheet, and the electrical connection position of the two is located below the chip.

After adopting the above technical solution, the space Q between the connector 70 and the front surface 51a is used to limit the mounting portion 90, so that the connector 70 can contact the locking portion 94 only when the space Q and the mounting portion 90 are well matched. After the connector 70 contacts the locking portion 94, the ground signal of the chip 20 can be transmitted normally.

Furthermore, a portion of the connector 70 may also be accommodated in the space Q. For example, one side of the connector 70 is arranged in an "n" shape, and a portion of the connector 70 is also arranged in the space Q. As shown in FIG. 56 , the connector 70 further includes an extension portion 710, and the extension portion 710 is arranged in the space Q, between the space Q and the front surface 51a. Under such a structure, the space Q is still arranged between the connector 70 and the front surface 51a. As long as a portion of the connector 70 meets this description, it meets the characteristics of forming a space Q between the connector 70 and the front surface 51a.

The space Q formed between the connector 70 and the front surface 51a can accommodate the front wall 97aa of the tray 97. The space Q and the front wall 97aa are limited, and the conductive member itself is in contact with the grounding component. Further, the bottom of the accommodating cavity has a bottom wall 97bb, and the grounding component can also be the bottom wall 97bb of the accommodating cavity.

53 to 56, it can be seen that a portion of the connector 70 is connected to the chip 20, and another portion is connected to the grounding component of the mounting portion 90. The connector 70 serves as both a mechanical means and a chip signal detection means to ensure that the ink cartridge is correctly installed on the mounting portion 90 of the printer.

The space Q between the connector 70 and the front surface is used to match the front wall 97aa of the tray 97. Only when the front wall 97aa enters the space Q, the tray 97 and the ink cartridge 10 are properly installed and positioned. When the assembly is installed in the installation portion 90, the connector 70 contacts the upper surface of the locking portion 94, and the chip model detection can be completed, and the ink cartridge 10 can be guaranteed to pass the detection of the chip signal detection means; the mechanical means and the chip signal detection means are combined to more comprehensively ensure that the ink cartridge is correctly installed on the printer.

Further, it should be noted that the ink cartridge 10 includes a chip 20, a bottom shell 51, an ink bag 10a, a connector 70, holes 220 and 210, a front surface 51a located in the +Y axis direction, a bottom surface 51b located in the +Z axis direction, and an ink outlet 41. The tray 97 has a front wall 97aa, and positioning holes 971 and 972.

The locking portion 94 has an upper surface 94a in the -Z axis direction. When the ink cartridge 10 is mounted on the mounting portion 90, the ink supply portion 92 (ink injection tube) matches the ink outlet 41 and can provide ink for the printer to print. The printer's contact pin assembly 91 contacts the communication terminal of the chip 20 to provide chip signal transmission.

The columnar positioning portions 93f, 93s cooperate with the positioning holes 971 and 972 on the tray 97 and the holes 220 and 210 on the ink cartridge to limit the position of the assembly in the mounting portion; the protrusion 941 on the locking portion 94 is used to cooperate with the groove at the bottom of the tray 97 to fix the assembly consisting of the ink cartridge 10 and the tray 97; the connecting member 70 cooperates with the front wall 97aa of the tray 97 and the connecting member 70 contacts the upper surface 94a of the locking portion 94 to transmit the ground signal.

The fifth implementation of the third embodiment:

On the basis of the above-mentioned embodiment, another antenna-type conductive component is provided in this embodiment, wherein the conductive component is composed of a conductive sheet and a conductive film of a part of the ink bag, and is specifically implemented as follows:

The conductive component provided in this embodiment includes a first conductive sheet 71 and a first conductive transmission medium body; the ink cartridge body includes an ink storage portion, the ink storage portion has an ink containing cavity surrounded by a film layer structure; the film layer structure includes an insulating outer film, a conductive intermediate film and an insulating inner film stacked in sequence from the outside to the inside; the conductive intermediate film is configured as a first conductive transmission medium body, and at least part of the conductive intermediate film is used to electrically connect the first conductive sheet to the top wall of the containing cavity.

Exemplarily, as shown in Figures 57 and 58, the ink cartridge in this embodiment includes an ink storage portion disposed in the ink cartridge body, the ink storage portion is configured as an ink bag 10a, the ink bag 10a has an ink containing cavity surrounded by a membrane layer structure, and the ink containing cavity is used to store ink.

For example, the ink bag has an upper surface and a lower surface, and the upper surface and the lower surface are the outer surfaces of the film structure. The film structure includes an insulating outer film, a conductive intermediate film and an insulating inner film arranged in sequence from the outside to the inside, the insulating outer film forms the outer surface of the ink bag, and the outer surface includes the upper surface and the lower surface, the insulating inner film forms the inner surface of the ink bag and contacts with the ink, the conductive intermediate film is arranged between the insulating outer film and the insulating inner film, and at least part of the conductive intermediate film can be used as the first conductive transmission medium body, so as to be regarded as a part of the conductive component, and part of the conductive intermediate film can be electrically connected to the grounding component.

In the embodiment of the present application, part of the conductive intermediate film is exposed to the outer surface of the film structure and forms a first electrical connection portion, which can be electrically connected to the first conductive sheet, and the other end of the first conductive sheet is electrically connected to the ground terminal of the chip. For example, the insulating outer film includes a first hollow portion, the first hollow portion is arranged close to the first conductive sheet, and part of the conductive intermediate film is exposed to the first hollow portion and forms the first electrical connection portion.

Part of the conductive intermediate film is exposed on the outer surface of the film layer structure to form a second electrical connection portion, which may be opposite to the first electrical connection portion and electrically connected through the unexposed conductive intermediate film therebetween, and is electrically connected to the grounding component.

For example, the insulating outer film includes a second hollow portion, at least part of the conductive intermediate film is exposed in the second hollow portion, and a second electrical connection portion is formed, and the second electrical connection portion is electrically connected to the first electrical connection portion through part of the conductive intermediate film to transmit a grounding signal; that is, the grounding signal between the chip and the printer is transmitted through the first conductive sheet, the intermediate conductive film, and the grounding component. This arrangement improves the grounding stability of the ink cartridge and reduces the situation where the grounding cannot be achieved or the grounding is unstable.

Based on the above embodiment, in this embodiment, the grounding component can be the outer frame of the mounting part 90 (the outer frame in the +Z axis, -Z axis, +X axis, -X axis, and +Y axis directions) or a part of the outer frame, for example, the cavity wall of the accommodating cavity is used as the grounding component, the first electrical connection part is located on the Y-axis side of the ink bag 10a, the above-mentioned second electrical connection part is located on the -Y-axis side of the ink bag, and the second electrical connection part is on the -Z-axis side of the first electrical connection part, that is, the second electrical connection part is closer to the cavity wall of the accommodating cavity than the first electrical connection part.

It should be noted that the membrane structure of the local area on the surface of the ink bag 10a has four layers of membrane: along the direction from the outside to the inside of the ink bag 10a, the first layer of membrane is made of PET material, so the first layer of membrane is also called PET membrane, that is, an insulating outer membrane; the second layer of membrane is made of Al material and is conductive, also called aluminum film, metal film or intermediate conductive film 10a1; the third layer of membrane is nylon membrane; the fourth layer of membrane is made of PET140 material, so the fourth layer of membrane is also called PET140 membrane.

However, other areas on the surface of the ink bag 10a are only provided with three layers of film, that is, the area is exposed to the outer surface of the film layer structure, and along the direction from the outside to the inside of the ink bag 10a, the aforementioned conductive film 10a1, nylon film and PET140 film are provided in sequence. Since the conductive film 10a1 is located at the outermost side in these areas, these areas are also called conductive areas of the ink bag 10a. In other words, the conductive areas form electrical connections. Among them, the conductive films 10a1 in all areas of the ink bag 10a are connected, that is, whether it is an area on the ink bag 10a where three layers of film are provided or an area where four layers of film are provided, they all have the same layer of conductive film 10a1. At the same time, the conductive film 10a1 is isolated from the ink stored in the ink bag 10a, so in this solution, the ink does not participate in the transmission of the ground signal.

In the embodiment of the present application, a portion of the first conductive sheet 71 is connected to the chip 20, and another portion is connected to the conductive film of the conductive area A of the ink bag 10a (first electrical connection portion). The first conductive sheet 71 has a first portion 71a and a second portion 71b. The first portion 71a is connected to the chip 20, and the second portion 71b is connected to the conductive film.

After the conductive film of the conductive area A is connected to the first conductive sheet 71, the -Z axis side of the connection between the two is covered with a PET film to make the appearance of the ink cartridge 10 more beautiful, or the connection between the two is fixed with an adhesive (such as tape, etc.) to make the connection between the first conductive sheet 71 and the first electrical connection part more stable.

As shown in Figure 59, in this embodiment, the -Y-axis side end of the ink bag 40 extends in the -Z-axis direction, and the -Z-axis side surface of the end has a conductive area B, which is the second electrical connection part. The conductive film 10a1 of the conductive area B is connected to the metal part 96 of the +Z-axis side outer frame of the mounting part 90, and the metal part 96 is the cavity wall forming the accommodating cavity, thereby realizing the transmission of the ground signal between the chip 20 and the printer 1.

It should be noted that a conductive area can be set at any position of the ink bag 10a, and the conductive film in the area can be connected to the metal part 96 of the mounting part 90. For example, except for the -Y axis side end of the ink bag 10a, the conductive film at the +Y axis side, +X axis side, -X axis side, -Z axis side or +Z axis side of the ink bag 10a can be connected to the metal part 96 of the mounting part 90.

As shown in Figures 60 and 61, on the basis of the above-mentioned embodiment, the ink cartridge provided in the embodiment of the present application also includes a second conductive sheet 72, and the second conductive sheet 72 and the first conductive sheet 71 are arranged at an interval, and the second conductive sheet 72 has a first part 72a and a second part 72b, the first part 72a is connected to the conductive film on the conductive area C of the ink bag 10a, and the second part 72b is connected to the metal part 96 of the mounting part 90, and the ground signal is transmitted to the chip 20 through the metal part 96, the second conductive sheet 72, the conductive film, and the first conductive sheet 71; and the -Y-axis side end of the ink bag 40 is not in direct contact with the metal part of the mounting part 90.

Optionally, after the conductive film of the conductive area C is connected to the second conductive sheet 72, the -Z axis side of the connection between the two is covered with a PET film to make the appearance of the ink cartridge 10 more beautiful, or the connection between the two is fixed with an adhesive (such as tape, etc.) to make the connection between the second conductive sheet 72 and the conductive film 10a1 more stable.

In the above solution, the metal parts of the mounting portion 90 can be the outer frame of the mounting portion 90 (the outer frame in the +Z axis, -Z axis, +X axis, -X axis, +Y axis directions) or a part of the outer frame. For the safety of the user, the metal parts of the mounting portion 90 are all grounded, and the grounding signal between the printer is connected.

In this embodiment, the second conductive sheet 72 extends from the conductive area C of the ink bag 10a first in the -Z axis direction, then extends to the -X axis side or the +X axis side until it crosses the tray 97, and then extends to the +Z axis direction and is connected to the outer frame on the +Z axis side of the mounting portion 90.

It should be noted that the number of the second conductive sheet 72 is not limited, for example, one or more can be provided, and the position of the second conductive sheet 72 on the ink bag 10a is also not limited, for example, it can be provided on the upper surface or the lower surface of the ink bag 10a, and can be provided on the +X axis side, -X axis side, +Y axis side or -Y axis side of the ink bag 10a. Sixth implementation of the third embodiment:

Figure 62 is a schematic diagram of the ink cartridge of the sixth embodiment of the third embodiment of the present application. The description of the ink cartridge of this embodiment is consistent with the fourth embodiment of the third embodiment, and the chip used is the first variant of the chip or the third variant of the chip, which will not be repeated here.

The seventh implementation method of the third embodiment:

Figure 63 is a schematic diagram of the ink cartridge of the seventh embodiment of the third embodiment of the present application. The description of the ink cartridge of this embodiment is consistent with the first to third embodiments of the third embodiment, and the chip used is the first variant of the chip or the third variant of the chip, which will not be repeated here.

Embodiment 4:

On the basis of the above-mentioned embodiment 1, the embodiment of the present application further includes a conductive support plate 82, and the mounting portion 90 is slidably arranged on the guide rail 86; the guide rail 86 and the conductive support plate 82 support are provided with a blocking plate 85; the conductive support plate 82 is arranged on the side of the blocking plate 85 away from the mounting portion, and the length direction of the conductive support plate 82 is consistent with the extension direction of the grounding guide rail 80, for example, the conductive support plate 82 is arranged parallel to the horizontal plane, and the conductive support plate 82 and the conductive wall plate 81 are arranged on both sides of the grounding guide rail 80. Correspondingly, the conducting component includes a bridging portion, so that the conducting component passes over the blocking plate 85, that is, the bridging portion is arranged above the blocking plate 85, and the portion of the bridging portion close to the conductive support plate can contact and be electrically connected with the conductive support plate.

As shown in FIG. 66 , the guide rail 86 may be a conductive component carrying a ground signal, or may be a non-conductive component not carrying a ground signal. When the guide rail 86 carries a ground signal, its conductive support plate 82 may be a part of the guide rail, or the guide rail 86 and the conductive support plate 82 may belong to two different components. The blocking plate 85 is a non-conductive component not carrying a ground signal (for example, the blocking plate 85 is made of non-conductive plastic), so in this embodiment, the conductive component must cross the blocking plate 85 to abut against the conductive support plate 82 to achieve the beneficial effects of the present application.

Specifically, as shown in Figures 64 and 65, in this embodiment, the chip 20 is arranged on the front end side of the installation direction of the ink cartridge 10, and the memory 100 is arranged on the rear surface 120b of the chip 20. A conductive sheet 140a is also provided between the chip 20 and the ink cartridge 10. The shape of the conductive sheet 140a is roughly consistent with that of the chip 20. An opening 111 consistent with the shape of the memory 100 is provided in the middle of the conductive sheet 140a. The size of the opening 111 is just enough to accommodate the protruding part of the memory 100. The grounding terminals 137a and 137b are bonded and connected to the chip 20 and the conductive sheet 140a after the installation is completed.

The connector 140 is configured as a conducting component. The connector 140 (equivalent to the conducting component) is made of a conductive material with a certain hardness. One end of the connector 140 (equivalent to the conducting component) is connected to the conductive sheet 140a by solder. Of course, the connector 140 and the conductive sheet 140a can be an integrally formed sheet metal part, or a structure composed of multiple parts. Optionally, the conductive sheet 140a may not be provided in this embodiment, and the connector 140 (equivalent to the conducting component) can be directly connected to the ground terminal to achieve the function of transmitting the ground signal.

As shown in Figures 66 to 70, the other end of the connector 140 can extend along the first side wall 50a of the ink cartridge body 50 in the -Y axis direction, or along the second side wall of the ink cartridge body in the +Y direction (arranged opposite to the first side wall 50a, not shown in the figure), or along the top wall 50d of the cartridge body in the +Z direction, in a direction away from the chip 20 to the rear side wall of 10, until it is close to the end side of the connector 140, and the connector 140 is bent in a direction away from the surface of the ink cartridge 10 to form a bridging portion 140b, and is connected to the conductive support plate 82 of the ground rail. Further, the ground signal between the chip 20 and the printer is transmitted through the conductive sheet 140a, the connector 140, and the conductive support plate 82.

It should be noted that the guide rail 86 is a component for supporting the mounting portion 90. For the safety of the user, the grounding signals between the guide rail 86 and the printing device are all connected. The conductive support plate 82 is a metal component in the printing device. For the safety of the user, the grounding signals between the conductive support plate 82 and the printing device are all connected. In this way, after adopting the above technical solution, the grounding signal is transmitted to the chip 20 through the conductive support plate 82 and the connector 140, which improves stability and reduces the situation where the grounding cannot be connected or the grounding is unstable, thereby achieving the beneficial effects of the present application.

On the basis of the above embodiment, in the embodiment of the present application, an abutment portion is provided at one end of the conductive member close to the grounding component, and the abutment portion is configured to contact the above conductive support plate 82 to electrically connect the conductive member to the conductive support plate 82 and the conductive wall plate.

Furthermore, since the mounting portion is slidably mounted on the guide rail, in order to ensure the smooth sliding of the mounting portion, the abutting portion in the embodiment of the present application can be configured as a ball or a ball bearing, and the ball and the ball bearing are part of the conductive component and are electrically connected to the conductive component. This arrangement can reduce the friction between the abutting portion and the conductive support plate or the conductive wall plate, ensuring that the mounting portion and the ink cartridge 10 slide smoothly on the grounding guide rail.

In another embodiment, the conductive component includes not only a second conductive sheet, but also a second conductive transmission medium electrically connected to the second conductive sheet, and a carrier electrically connected to the second conductive transmission medium, that is, the conductive component in this embodiment is composed of a conductive sheet, a conductive transmission medium and a carrier.

Furthermore, the carrier is arranged close to the chip, that is, the carrier is located at an end of the ink cartridge body away from the guide rail. One end of the carrier is connected to the ground terminal of the chip, and the other end of the carrier extends into the ink chamber of the ink cartridge body and is electrically connected to the printing liquid medium in the ink chamber. For example, the printing liquid medium is ink, and the ink is connected to the carrier as a conductive medium, so that the ground signal of the ground terminal is transmitted to the ink through the carrier.

Furthermore, one end of the second conductive sheet extends into the ink containing cavity and is able to contact the ink. The other end of the second conductive sheet forms a jumper portion and is spanned over the blocking plate 85 through the jumper portion. The jumper portion can be electrically connected to the conductive support plate, so that the ground signal is transmitted from the ink through the second conductive sheet to the conductive support plate.

Exemplarily, as shown in Figure 71, the connecting member 140 is configured as the above-mentioned second conductive sheet, which is a part of the conductive component and is made of a conductive material with a certain hardness. The connecting member 140 can be an integrally formed sheet metal part or a structure composed of multiple parts. The embodiment of the present application is not limited to this.

The connecting member 140 also includes a fixing member 141, which can be made of silicone material. The middle part of the fixing member 141 has a through hole that can accommodate the bent portion 1402 of the connecting member 140. The connecting member 140 is installed as follows: first, the fixing member 141 is inserted into the connecting member 140, and then the vertical portion 1401 of the connecting member 140 with the fixing member 141 is inserted into the through hole on the upper part of the rear side wall 50b of the ink cartridge 10, and then the position of the fixing member 141 is adjusted to block the above-mentioned through hole and make the connecting member 140 in a preset position and posture relative to the ink cartridge 10.

As shown in FIG. 73 , the state of the connector 140 after installation is as follows: the vertical portion 1401 of the connector 140 is attached to the inner side of the rear side wall 50b in the ink cartridge 10, extending from the bottom of the rear side wall 50b near the ink outlet 41 end along the +Z axis direction to the top of the rear side wall 50b, and is fixed to the ink cartridge 10 by the fixing member 141. The fixing member 141 can seal the rear side wall 50b, not only to prevent ink leakage but also to fix the connector 140. The bent portion 1402 of the connector 140 extends from the through hole of the fixing member 141 to the outside of the ink cartridge 10, bends in a direction away from the surface of the ink cartridge 10, and is connected to a metal part on the printer, which is the above-mentioned conductive support plate 82.

As shown in Figures 72 and 75, the conductive member 140a is the above-mentioned carrier, which is made of conductive silicone material as a whole and is embedded in the mounting surface of the ink cartridge 10, and can seal the ink cartridge 10 and contact the ink. Specifically, the conductive member 140a is placed behind the chip 20, and the memory 100 is set on the rear surface 120b of the chip 20. The conductive member 140a is provided with an opening 111, and the opening 111 is arranged in cooperation with the memory 100 so that the size of the opening 111 is just enough to accommodate the memory 100.

In the installed state, the chip 20 is at least partially in contact with the conductive member 140a on the side corresponding to the rear surface 120b, and the seventh terminals 137a and 137b (ground terminals in this application) are both against the conductive member 140a. The first surface 140b of the conductive member 140a is used to connect to the chip 20, and the second surface 140c (facing the internal accommodating cavity of the ink cartridge 10) is in contact with the ink and electrically connected.

As shown in FIG. 76 and FIG. 77 , the connecting member 140 is placed in the -X axis direction of the ink cartridge 10, and the conductive member 140a is placed in the +X axis direction of the ink cartridge 10. Since the ink in the ink cartridge 10 has conductive properties, in this embodiment, the ground signal between the chip 20 and the printer can be transmitted through the conductive member 140a, the ink, the connecting member 140, and the conductive support plate 82.

Of course, the ink cartridge grounding method involved in this embodiment is also applicable to other types of chips. For example, the chip 20 has four terminals on the front and a grounding terminal (not shown in the figure) on the back. The grounding terminal can also transmit the grounding signal between the chip and the printer by means of the conductive member 140a, ink, the connecting member 140, and the conductive support plate 82. (The component 1401 is in the cavity of the ink cartridge and is electrically connected to the ink)

After adopting the above technical solution, the ground signal is transmitted to the chip 20 through the conductive support plate 82, the connecting member 140, the ink, and the conductive member 140a, thereby improving stability and reducing the situation where the grounding cannot be achieved or the grounding is unstable. When the ink in the ink cartridge 10 is used up or is about to be used up, the ground signal on the chip 20 cannot be connected to the printer, and the printer will display a prompt that the ink cartridge is not installed. This can have the same function as the signal of the printer itself indicating that the ink is exhausted to warn the user to replace the ink cartridge.
