Fig. 3 is a schematic diagram of the chip 80 according to the first embodiment. FIG. 6 is a schematic view of the ink cartridge 10 according to the first embodiment. As shown in fig. 3 and 6, the chip 80 is mounted on the ink cartridge 10, electrically connected to the inside of the printer, and responsible for transmission of electrical signals. The ink cartridge 10 includes a chip 80, a handle 30, an ink outlet 40, and a cartridge body 50. The handle 30 has a coupling portion that is coupled to a fixing portion in the printer when the ink cartridge 10 is mounted to the mounting portion 90, and prevents the ink cartridge 10 from being separated from the mounting portion 90 in the + Z-axis direction. The cartridge 50 stores ink, the ink reaches the ink supply portion 92 through the ink outlet 40, and the ink supply portion 92 can supply the ink to the print head, so that the ink can be used for printing. When the ink cartridge 10 is mounted on the mounting portion 90, the chip 80 contacts the plurality of contact pins 911-919 in the mounting portion 90. The chip 80 has: a first substrate 11 and a second substrate 12. The first substrate 11 is provided with a first terminal 801-; the second substrate 12 is provided with second terminals 808-. The first substrate 11 and the second substrate 12 are electrically connected; the first terminals 801-.

The first terminals include first substrate terminals 801 to second substrate terminals 807. The second terminals include eighth substrate terminal 808 to ninth substrate terminal 809. The first substrate terminal 801 is in contact with the first portion 911a of the first contact pin 911, and the area in contact with the first contact pin 911 is a first substrate contact area. The second to seventh substrate terminals 802 to 807 have a uniform arrangement, structure with the first substrate terminal 801, and detailed illustration and explanation thereof will not be provided here. The first substrate terminal 801 to the seventh substrate terminal 807 have first substrate contact areas to seventh substrate contact areas, collectively referred to as substrate contact areas, respectively, which are arranged in a plurality of rows in the Z-axis direction. The first substrate terminal 801 to the second substrate terminal 807 are provided on the front surface 11A of the first substrate 11. Eighth substrate terminals 808 to ninth substrate terminals 809 are provided on the front surface 12A of the second substrate 12. Specifically, the eighth substrate terminal 808 to the ninth substrate terminal 809 are provided protruding from the front surface 12A. The first substrate terminals 801 to the seventh substrate terminals 807 are arranged in two rows in the Z-axis direction, the first substrate terminal 801 to the fourth substrate terminal 804 are in the first row, and the fifth substrate terminal 805 to the seventh substrate terminal 807 are in the second row along the-Z-axis direction; further, along the-Z axis, the first substrate contact area-the fourth substrate contact area are on the first row and the fifth substrate contact area-the seventh substrate contact area are on the second row. The center line L1 passes through the center point in the Y-axis direction of the chip 80 and is parallel to the Z-axis direction. The center line L1 passes through the sixth substrate terminal 206. The eighth substrate terminal 808 to the ninth substrate terminal 809 are symmetrically distributed on the chip 20 with the center line L1 as a center of symmetry. Further, the chip 20 is symmetrical with the center line L1 as a symmetry center.

The eighth contact pin 918 and the ninth contact pin 919 are applied with a high voltage (for example, a square wave of 42V) inside the printer to detect the ink capacity of the ink cartridge 10 or to detect whether the ink cartridge 10 is mounted on the mounting portion 90. The memory (not shown) has a low operating voltage, so that the printer applies a low voltage (2.7V to 3.3V) to the first to seventh contact pins 911 to 917 and the memory. Some or all of the first terminals are connected to the memory. The first terminals 801-. In the chip, the second substrate 12 is electrically connected to the first substrate 11, the first substrate 11 has a first terminal 801-. The first substrate 11 and the second substrate 12 are independent and are not electrically connected to each other. The high pressure is completely separated from the low pressure. With this structure, the possibility of short circuit between the first terminals 801 and 807 and the second terminals 808 and 809 is greatly reduced.

Further, the first substrate terminal 801 and the fourth substrate terminal 804 are provided with a function of detecting a short circuit. Specifically, if the first substrate terminal 801 and the eighth substrate terminal 808 are connected together due to a short circuit caused by a foreign object or ink, the internal printer circuit may detect that a voltage different from a predetermined range is applied to the first substrate terminal 801 (for example, detect that a higher voltage is applied to the first substrate terminal 801), and then send an abnormal signal to notify the user that the chip 80 or the ink cartridge 10 is abnormal and needs to be processed. Further preventing the possibility of short circuits.

The first substrate 11 further includes a first concave portion 111 and a second concave portion 112. The positions of the first and second recesses 111, 112 are set such that, when the ink cartridge 10 is mounted on the mounting portion 90, the eighth and ninth contact pins 918, 919 are located in the first and second recesses 111, 112, and the first and second recess surfaces 111a, 112a block and insulate the eighth and ninth contact pins 918, 919, thereby preventing the eighth and ninth contact pins 918, 919 from contacting the first terminal, increasing the safety of the chip 80, and preventing the chip 80 and the circuit in the inkjet printer from being damaged.

The eighth substrate terminal 808 is electrically connected to the first vertical portion 918k of the eighth contact pin 918 because the eighth substrate terminal 808 is disposed to protrude from the front surface 12A of the second substrate 12 and has no elasticity. When the ink cartridge 10 is mounted on the mounting portion 90, the eighth substrate terminal 808 presses the first vertical portion 918k of the eighth contact pin 918, so that the first vertical portion 918k moves in the + X-axis direction, the eighth substrate terminal 808 enters the eighth slit 988, and the + X-axis side of the eighth substrate terminal 808 is inserted into the eighth slit 988, so that the chip 80 is positioned, and the accuracy of contact between the chip 80 and the contact pin is improved. The ninth substrate terminal 809 has the same contact form and function as the eighth substrate terminal 808, and a detailed explanation thereof will not be provided here.

Further, the second terminals 808 and 809 are located in the + Z axis direction of the first terminals 801 and 807. The structure makes the first terminals 801-. The second substrate 12 is located in the + Z-axis direction of the first substrate 11. The structure enables the two substrates to be distributed at intervals in the Z-axis direction, and further avoids the possibility of short circuit between the first terminal 801-.

On the other hand, the first substrate 11 is fixed to the second substrate 12, for example, the first substrate 11 is fixed to the second substrate 12 to form a chip assembly. The first substrate 11 and the second substrate 12 can be fixed together by pasting, adhering, gluing, clamping, etc., but the first substrate 11 and the second substrate 12 are mutually insulated, i.e. they are not electrically connected, so that the possibility of short circuit between the first terminal 801 and the second terminal 807 and 808 and 809 can be greatly reduced.

It will be understood that there may also be a distance in space between the first substrate 11 and the second substrate 12, i.e. there may not be a direct connection between the two, e.g. there may be a connection through a third substrate (not shown in the figures), or there may be a gap between the two (i.e. there is no physical connection between the two). For example, when mounting, the first substrate 11 and the second substrate 12 are mounted on the chip holder or the ink cartridge, respectively. The first substrate 11 and the second substrate 12 may be disposed vertically, parallel or obliquely, and the front surface 11A of the first substrate 11 and the front surface 12A of the second substrate 12 may also be disposed vertically, parallel or obliquely, as long as the first substrate 11 and the second substrate 12 are insulated from each other.

The chip 80 may be fixed to the ink cartridge 10 by fitting the recess to the projection, or may be fixed to the ink cartridge 10 by adhesion or the like.

Example two

Fig. 7 is a schematic view of a second substrate of the second embodiment. The second substrate 12 has a second terminal 810, the second terminal 810 being a unitary terminal made of the same material and contacting at least two contact pins of the plurality of contact pins to form at least two contact areas 808a, 809 a. The at least two contact areas 808a, 809a are made of non-metallic material.

In this embodiment, the second terminal is an integral terminal made of non-metal such as conductive silicone or carbon. The second terminals 810 are in contact with the eighth and ninth contact pins 918, 919 forming eighth and ninth contact areas 808a, 809 a. In normal operation of the printer, a high voltage is applied to the second terminal 810 by the eighth and ninth contact pins 918, 919. And a high resistance value (for example, 62K Ω) needs to be connected between the eighth contact pin 918 and the ninth contact pin 919, so that the printer and the chip 80 can normally work. The two contact areas are made of non-metal materials, so that the resistance value between the two contact areas can reach the resistance value required by the normal working state of the printer and the chip 80.

The rest is consistent with the embodiment.

The second substrate 12 is made of a non-metal material such as conductive silicon or carbon, and is in contact with at least two contact pins of the plurality of contact pins to form at least two contact areas 808a and 809 a. The second substrate 12 is made of only one non-metallic material so that the resistance between the contact areas 808a, 809a can reach the resistance required for normal operation of the printer and the chip 80.

The rest is the same as the second embodiment.

With the present embodiment, the second terminals 121a of the second substrate 12a are provided in an inward concave shape, so that the contactable area of the second terminals 121a with the contact pins is increased, and the second terminals 121a have a larger width and are not easily broken; in addition, the second terminals 121a are engaged with the elongated portions (i.e., the vertical regions) of the contact pins by the recessed portions thereof, so that the contact pins are restricted in the recessed portions, and even if the chip 80 moves along with the mounting portion 90, the contact failure due to displacement between the contact regions and the contact pins is not likely to occur.

The rest is consistent with the embodiment.

EXAMPLE six

The first terminal on the first substrate 11 is a terminal for receiving low voltage, the second terminal on the second substrate 12 is a terminal for receiving high voltage, and because the high voltage terminal and the low voltage terminal are located on different substrates, the contact areas formed by the contact of the high voltage terminal and the low voltage terminal and the contact pins are not on the same plane, when ink drops between the high voltage terminal and the low voltage terminal, a loop is not easily formed, the risk of damaging a memory due to short circuit between the high voltage terminal and the low voltage terminal is reduced, and the printing device can normally work.

As shown in fig. 9, 13 and 17, a notch is formed between the two second terminals 121a, 121b of the second substrate 12, the first substrate 11 can be mounted in the notch, and the width of the notch can be the same as the width of the first substrate 12 in the terminal row arrangement direction, so that the second substrate 12 and the first substrate 11 can be engaged, and the second substrate 12 is engaged with the upper half portion of the first substrate 11, so as to fix the relative position therebetween, so that the contact between the terminals and the contact pins is not easily displaced, and the contact stability between the terminals and the contact pins is further enhanced.

As shown in fig. 17, the second board 12 is further provided with a short detection terminal 123, and when the first board 11 and the second board 12 are engaged so that the first terminal and the second terminal are in the same line, the short detection terminal 123 is located between the first terminal and the second terminal, and when the first terminal and the second terminal are short-circuited due to ink contamination, the short detection terminal 123 is contaminated by ink at a high rate, so that whether the first terminal and the second terminal are short-circuited or not can be detected in time, and the memory circuit is further protected from being damaged by erroneously applying a high voltage.

The rest corresponds to example four.

EXAMPLE seven

As shown in fig. 18, the first substrate 11 is further provided with a notch 118, and when the second substrate 12 is combined with the printing apparatus and contacts with the contact pins, the second terminal on the second substrate 12 passes through the notch 118 and contacts with the corresponding contact pin, so that the width of the second substrate 12 can be reduced, and the second substrate 12 can be made smaller.

The rest corresponds to example four.

Example eight

As shown in fig. 19 to 21b, the second terminals 808 and 809 are positioned with the second substrate 12 through the positioning holes 808a to 809 a. Preferably, the positioning portions 808a, 809a are through holes on the second substrate 12. Further, the second terminals 808 and 809 are soldered on the second substrate 12 by soldering. The second terminals 808 and 809 are two independent metal pieces.

As shown in fig. 20 and 21a, the left second terminal 808 has: a first portion 808A contacting the eighth contact pin 918, a second portion 808B fixed on the second substrate 12, and a third portion 808C connecting the first portion 808A and the second portion 808B. The second portion 808B is fitted with a positioning portion (positioning hole 808a in this embodiment) for positioning the left second terminal 808. The left second terminal 808 has a contact area 8082 that contacts the first vertical portion 918k of the eighth contact pin 918. Contact area 8082 is located at the + X axial end of the first portion 808A of the left second terminal 808, and further, contact area 8082 is located at the + X axial end of the left second terminal 808. The first portion 808A is perpendicular to the third portion 808C, and the second portion 808B is perpendicular to the third portion 808C; the third portion 808C is disposed on and parallel to the front surface 80a of the second substrate 12.

The left second terminal 808 includes: first surface 808e, second surface 808b, third surface 808c, fourth surface 808d, and fifth surface 808 f. First surface 808e is parallel to and opposite second surface 208b, which are parallel to front surface 80 a. Third surface 808c is disposed parallel to and opposite fourth surface 808 d. Third surface 808c and fourth surface 808d are located on the-Y axis side and the + Y axis side of left second terminal 808, respectively. First surface 808e, second surface 808b are also two surfaces of third portion 808C. Third surface 808c and fifth surface 808f are two surfaces of first portion 808A, and are disposed in parallel and opposite to each other. Third surface 808c and fifth surface 808f are located on the-Y axis side and the + Y axis side of left second terminal 808, respectively.

The first portion 808A is perpendicular to the third portion 808C, and the second portion 808B is perpendicular to the third portion 808C, so that the second substrate 12 has a simple structure and high production efficiency. Meanwhile, the contact area between the second terminal and the second substrate 12 is increased, and the positioning position between the second terminal 808 and 809 and the second substrate 12 is increased, so that the design of the second portion 808B is simple and easy to operate, and the assembly of the second terminal 808 and 809 and the second substrate 12 is easy. Further, the first portion 808A is prevented from being deformed due to the influence of the welding, bonding, or other processes. The deformation of the first portion 808A may result in inaccurate contact with the eighth contact pin 918. The third portion 808C is disposed on the front surface 80a and parallel thereto, so that in the reproduction process, the second terminal can be mounted, positioned and soldered only on the front surface of the second substrate 12 without turning to the back surface of the second substrate 12, which is convenient for production and improves the production efficiency. Second portion 808B is four protrusions from third portion 808C, the four protrusions being perpendicular to front surface 80 a; the positioning holes 808a are used to match with the second part 808B, and the four protrusions are inserted into the positioning holes 808a, so that the installation of the left second terminals 808 is simpler and more convenient.

Further, the + X axis side of the second portion 808B has a flat surface 808h, the flat surface 808h is parallel to the second surface 808B, and the protrusion of the second portion 808B has a taper 8081 therein, i.e., the width of the protrusion is narrower closer to the flat surface 808h, that is, the width of the taper 8081 is narrower along the + X axis direction. The structure is helpful for playing a guiding role in the process of matching the second terminal with the positioning hole 808a, thereby facilitating production and improving production efficiency.

In the X-axis direction, the first portion 808A and the second portion 808B are located on both sides of the third portion 808C, respectively.

Specifically, the third portion 808C and the second portion 808B are located on the + Y axis side of the first portion 808A. The right second terminal 209 has a uniform arrangement, structure with the left second terminal, and a detailed illustration and explanation thereof will not be provided here.

The number of the second portion of the second terminal and the number of the positioning holes 808a and 809a of the second substrate 12 may be one or more, and the positioning purpose can be achieved.

Further, after the second terminals 808 and 809 are soldered to the second substrate 12, the second terminals 808 and 809 are connected to devices on the second substrate 12 through wires on the second substrate 12, so that the second terminals 808 and 809 can work normally. For example: the second terminals 808, 809 are connected by wires to a resistor (for example, a resistor having a high resistance value of 62K Ω) provided on the second substrate 12, so that the printer can normally perform mounting detection through the second terminals.

Further, the second substrate 12 is fixed to the ink cartridge 10.

The assembly is first mounted on the second substrate 12, the second substrate 12 being mounted on the ink cartridge 10; or the assembly can be directly mounted on the ink cartridge 10 by injection molding or welding or snap-fitting or gluing (without the need for the second substrate 12).

Further, the device 120 may be a resistor in such a way that the printer can perform a mounting check normally through the second terminal.

Furthermore, the device 120 may also be carbon or silicon or other semiconductors, so that the combination also has a high impedance, enabling proper operation of the second terminal.
