As shown in fig. 2A and 2B, a connector 30 for electrical connection with a chip in a conventional inkjet printer includes a connection body 30a and first and second rows of contact pins 31 and 32 provided on the connection body, each row of contact pins being composed of a plurality of independent contact pins, wherein the first row of contact pins 31 is composed of first, second, third and fourth contact pins 31a, 31B, 31c and 32d arranged at intervals, the second row of contact pins 32 is composed of fifth, sixth, seventh, eighth and ninth contact pins 32A, 32B, 32c, 32d and 32e arranged at intervals, the respective contact pins are arranged alternately, and the fifth and ninth contact pins 32A and 32e are located at both ends, respectively.
Each stylus is generally triangular in shape and is retractable and extendable relative to the connecting body 30a in the direction indicated by B1B2 in fig. 2A. Taking the third contact pin 31c as an example, the contact pin 31c includes an upper surface 31c1, a lower surface 31c3, and a top 31c2 located between the upper surface 31c1 and the lower surface 31c3, and when the ink cartridge is mounted to the ink jet printer, the contact pin top 31c2 contacts with the chip terminals in the ink cartridge to establish a communication connection.
As the demand for miniaturization of inkjet printers increases, the size of the connecting member 30 and the size of each contact pin become smaller, and accordingly, the terminals of the chip in the ink cartridge for electrical contact with the contact pins become smaller, and thus, the manufacturing accuracy of the chip becomes higher.
Therefore, as described in chinese patents CN201510930940.5, CN201620837116.5 and CN201711397088.5, the contact pin upper surface 31c1 is contacted with the chip terminal to establish electrical connection, as shown in fig. 2-14 of CN201510930940.5, fig. 2-7 of CN201620837116.5 and fig. 8 and 11 of CN201711397088.5, part of the downstream of the terminal is hollowed along the mounting direction P, and during the process of mounting the ink cartridge in the inkjet printer along the mounting direction P, the terminal which is not hollowed downstream presses the corresponding contact pin to retract along the direction B1 in fig. 2A of the present invention until the contact pin top 31c3 is contacted with the terminal, as shown in fig. 21 of CN201510930940.5, the terminal which is hollowed downstream is contacted with the upper surface 321a of the contact pin; in general, the above-described conventional approach is to reduce the manufacturing accuracy of the chip by increasing the contact area of the terminals.

Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The present invention is based on the improvement of the chip 20 in the case that the handle 13 of the ink cartridge 10 is broken or eliminated, and therefore, the structural description and the part numbers of the connecting member 30 in the ink cartridge 10 and the ink jet printer in the background art will be continued hereinafter.
Example one
Fig. 3 is a schematic distribution diagram of chip terminals according to an embodiment of the present invention.
The chip 20 includes a substrate 21, a plurality of terminals provided on the substrate 21, and storage portions (not shown) connected to the terminals, the terminals and the storage portions being respectively located on both sides of the substrate 21, the terminals being used to make contact with the connector 30 in the inkjet printer to establish electrical connection, the storage portions being used to store information such as the amount of ink, the color of ink, and the like in the ink tank.
Generally, the number of terminals of the chip 20 is the same as the number of contact pins in the inkjet printer, i.e., one contact pin per terminal, and when the contact pins in the inkjet printer are divided into the first row of contact pins 31 and the second row of contact pins 32 as described in the background art, in order to reduce the manufacturing accuracy of the chip 20, the terminal distribution in the chip 20 in the present embodiment does not correspond to the contact pins in the inkjet printer, i.e., the terminals in the chip 20 are not distributed in two rows.
As shown in fig. 3, the chip 20 includes a first terminal 201, a second terminal 202, a third terminal 203, a fourth terminal 204, a fifth terminal 205, a sixth terminal 206, a seventh terminal 207, an eighth terminal 208, and a ninth terminal 209, wherein the first terminal 201 to the fourth terminal 204 are generally located upstream of the fifth terminal 205 to the ninth terminal 209 in the mounting direction a. Each terminal extends in a tapered shape in the direction B1B2 in fig. 2A, and specifically, as shown in fig. 3, the distance between the outermost sides of each terminal becomes smaller and smaller in the direction B1 when measured in the mounting direction a or a direction perpendicular to the mounting direction a, and thus, each terminal has a first surface located upstream and a second surface located downstream in the mounting direction a, and both the first surface and the second surface are inclined with respect to the mounting direction a.
Taking the first terminal 201 as an example, the first terminal 201 is tapered along the direction B1B2, the first terminal 201 has a first surface 201a located upstream and a second surface 201B located downstream along the mounting direction a, and both the first surface 201a and the second surface 201B are inclined with respect to the mounting direction a, and the distance between the first surface 201a and the second surface 201B is smaller in the direction B1 (the thickness of the chip 20) as measured along the mounting direction a.
In this embodiment, the first terminal 201, the second terminal 202, the third terminal 203, and the fourth terminal 204 are arranged in a staggered manner, and the fifth terminal 205, the sixth terminal 206, the seventh terminal 207, the eighth terminal 208, and the ninth terminal 209 are also arranged in a staggered manner; in the mounting direction a, the first terminal 201 and the fourth terminal 204 are located upstream of the second terminal 202 and the third terminal 203, and the fifth terminal 205 and the ninth terminal 209 are located upstream of the sixth terminal 206, the seventh terminal 207, and the eighth terminal 208.
When the ink cartridge with the chip 20 mounted thereon is mounted to an inkjet printer, the first contact pin 31a contacts the first terminal 201, the second contact pin 31b contacts the second terminal 202, the third contact pin 31c contacts the third terminal 203, the fourth contact pin 31d contacts the fourth terminal 204, the fifth contact pin 32a contacts the fifth terminal 205, the sixth contact pin 32b contacts the sixth terminal 206, the seventh contact pin 32c contacts the seventh terminal 207, the eighth contact pin 32d contacts the eighth terminal 208, and the ninth contact pin 32e contacts the ninth terminal 209.
The terminals in this embodiment are generally arranged so that when the terminals are in contact with the contact pins, the terminals do not contact the tops of the contact pins, but at least contact the lower surfaces of the contact pins, so that after the ink cartridge is mounted, the contact pins apply urging forces in the same direction as the mounting direction a to the ink cartridge through the terminals, the urging forces being offset at least by the elastic deformation force of the ink outlet elastic member, and thus, even if the ink cartridge 10 does not have the handle 13/detent 13a, the ink cartridge 10 can be stably mounted in the ink jet printer.
As shown in fig. 3, the first to sixth terminals 201 to 206, the eighth and ninth terminals 208 and 209 are all elliptical, and the seventh terminal 207 is circular, so that the upper or lower surfaces of the contact pins are in contact with the first to sixth terminals 201 to 206, the eighth and ninth terminals 208 and 209, and the upper and lower surfaces of the contact pins are simultaneously in contact with the seventh terminal 207. The second surfaces of the first and fourth terminals 201 and 204 are in surface contact with the lower surfaces of the first and fourth contact pins 31a and 31d, respectively, at the center points of the first and fourth contact points P1 and P4, respectively; the first surfaces of the second and third terminals 202 and 203 are in surface contact with the upper surfaces of the second and third contact pins 31b and 31c, respectively, at the center points of the contact, which are the second and third contact points P2 and P3, respectively; the second surfaces of the fifth and ninth terminals 205 and 209 are in surface contact with the lower surfaces of the fifth and ninth contact pins 32a and 32e, respectively, at center points of the fifth and ninth contact points P5 and P9, respectively; the first surfaces of the sixth and eighth terminals 206 and 208 are in surface contact with the upper surfaces of the sixth and eighth contact pins 32b and 32d, respectively, at the center points of the contact, which are the sixth and eighth contact points P6 and P8, respectively; the first and second surfaces of the seventh terminal 207 are brought into surface contact with the upper and lower surfaces of the seventh contact pin 32c, respectively, at the center points of the contact, P71 and P72, respectively.
As described above, the contact pins expand and contract in the direction indicated by B1B2, and therefore, when in contact with the upper surfaces of the contact pins, the contact pins exert a urging force on the chip in the direction opposite to the mounting direction a, and when in contact with the lower surfaces of the contact pins, the contact pins exert an urging force on the chip in the same direction as the mounting direction a.
Preferably, the urging force of the contact pin applied to the terminal in the same direction as the mounting direction a is larger than the urging force of the contact pin applied to the terminal in the opposite direction to the mounting direction a, and it is possible, for example, that the number of terminals in contact with the lower surface of the contact pin is not less than the number of terminals in contact with the upper surface of the contact pin, or that the urging force generated when the lower surface of the contact pin is in contact with the terminals is larger than the urging force generated when the upper surface of the contact pin is in contact with the terminals in the case where the number of contacts of the upper surface of the contact pin with the terminals is the same as the number of.
As shown in fig. 3, when the ink cartridge is mounted to the ink jet printer, assuming that the projected points of the tops of the first row of contact pins on the chip of the connecting member 30 are connected to form a first straight line L1, and the projected points of the tops of the second row of contact pins on the chip are connected to form a second straight line L2, the second surface of the first terminal 201 in this embodiment is in contact with the lower surface of the first contact pin, so that the first contact pin 31a will exert a pushing force F1 on the chip in the same direction as the mounting direction a, and the first surface of the second terminal 202 will be in contact with the upper surface of the second contact pin, so that the second contact pin 31b will exert a pushing force F2 on the chip in the opposite direction to the mounting direction a. Further, in the mounting direction a, the distance between the first contact point P1 and the first straight line L1 is h1, the distance between the second contact point P2 and the first straight line L1 is h2, and h1 < h2, that is, the first contact pin 31a is forced to retract more, and conversely, the reaction force exerted by the first contact pin 31a on the first contact pin 201 is greater, so that the above-mentioned forcing force satisfies F1 > F2.
Likewise, the distance from the fifth contact point P5 to the second straight line L2 is h3 and the distance from the sixth contact point to the second straight line is h4, h3 < h4 in the mounting direction a, that is, the fifth contact pin 32a is forced to retract more by the fifth terminal 205, and conversely, the reaction force exerted by the fifth contact pin 32a on the fifth terminal 205 is also greater, and therefore, the urging force exerted by the fifth contact pin 32a on the chip through the fifth terminal 205 is greater than the urging force exerted by the sixth contact pin 32b on the chip through the sixth terminal 206.
Accordingly, the urging force of the fourth contact pin 31d to the fourth terminal 204 is larger than the urging force of the third contact pin 31c to the third terminal 203, and the urging force of the ninth contact pin 32e to the ninth terminal 209 is larger than the urging force of the eighth contact pin 32d to the eighth terminal 208; finally, as a whole, the urging force of the printer feeler against the terminal in the same direction as the mounting direction a is larger than the urging force of the printer feeler against the terminal in the opposite direction to the mounting direction a, and the ink cartridge 10 can be stably mounted in the ink jet printer without a handle.
Preferably, the first contact point P1 and the fourth contact point P4 form a first connection line L11, the second contact point P2 and the third contact point P3 form a second connection line L12, the fifth contact point P5 and the ninth contact point P9 form a third connection line L15, and the sixth contact point P6 and the eighth contact point P8 form a fourth connection line L16, so that the forces applied by the contact pins to the chip are equalized, the ink cartridge 10 can be stably mounted in the ink jet printer, and the terminals arranged in a staggered manner reduce the requirement for the positional accuracy of the contact pins when the contact pins are brought into contact with the terminals.
With regard to the seventh terminal 207, since the upper surface of the seventh contact pin 32c is in contact with the first portion of the seventh terminal with the center point of contact being P71, the lower surface of the seventh contact pin 32c is in contact with the second portion of the seventh terminal with the center point of contact being P72, and the top of the seventh contact pin 32c is located on the second straight line L2, the urging forces from the seventh contact pin 32c received by the seventh terminal 207 cancel each other in the mounting direction a and the direction opposite to the mounting direction a.
On the other hand, since the seventh terminal 207 is circular, the first and second portions of the seventh terminal are in contact with the upper and lower surfaces of the seventh contact pins 32c, respectively, and thus, the seventh terminal 207 also functions as a positioning, and when the chip 20 is coupled with the connection member 30, the seventh contact pins 32c are caught in the seventh terminal 207 while emitting a "click" sound to prompt the user that the ink cartridge 10 has been mounted to a predetermined position.
In this embodiment, the seventh terminal 207 is located at the middle position between the fifth terminal 205 and the ninth terminal 209, which is beneficial to ensure the stress balance of the chip 20, however, the position of the circular terminal may be adjusted according to the positions of other terminals, for example, the terminals located at the ends of the first straight line L1 and the second straight line L2 are arranged in a circular shape, which also achieves the purpose of stably mounting the ink cartridge 10 in an inkjet printer.
Further, the seventh terminal 207 may be formed in an oval shape such that the lower surface of the seventh contact pin 32c contacts the seventh terminal 207, and at this time, the seventh contact pin 32c applies an urging force in the same direction as the mounting direction a to the chip 20/ink cartridge 10 through the seventh terminal, and the ink cartridge 10 may be stably mounted in the ink jet printer.
Example two
Fig. 4 is a schematic distribution diagram of chip terminals according to a second embodiment of the present invention.
In the present embodiment, the respective terminals of the chip are disposed so as to pass through the substrate 21, and in fig. 4, the distance between the outermost sides of the respective terminals is constant in the direction of B1B2, measured in the direction perpendicular to the mounting direction a and the direction in the same direction as the mounting direction a.
The first to ninth terminals 201 to 209 are redistributed in which the first to sixth terminals 201 to 206 and the eighth and ninth terminals 208 and 209 are all elliptical, the seventh terminal 207 is circular, the downstream of the first to fifth terminals 201 to 205 is in line contact with the lower surface of the corresponding contact pin, the upstream of the eighth and ninth terminals 208 and 209 is in line contact with the upper surface of the corresponding contact pin, and the upstream of the seventh terminal 207 is in line contact with the upper and lower surfaces of the seventh contact pin, respectively, along the mounting direction a, and thus the chip 20 is acted by the urging force exerted by the contact pins in the same direction as the mounting direction a, so that the ink cartridge 10 is stably mounted in the inkjet printer.
Similarly, in the chip 20, the urging force applied by the contact pins to the terminals in the same direction as the mounting direction a is greater than the urging force applied by the contact pins to the terminals in the opposite direction to the mounting direction a, and it is possible to realize, for example, that the number of terminals in contact with the lower surfaces of the contact pins is not less than the number of terminals in contact with the upper surfaces of the contact pins, or that the positional relationship between each contact point and the first straight line L1 and the second straight line L2 may be set to satisfy F1 > F2, where F1 refers to the urging force applied by the lower surfaces of the contact pins to the terminals in the same direction as the mounting direction a, and F2 refers to the urging force applied by the upper surfaces of the contact pins to the terminals in the opposite direction to the mounting direction a.
In the present embodiment, the contact points of the first to sixth terminals 201 to 206 and the eighth and ninth terminals 208 and 209 with the respective corresponding contact pins are a first contact point P1, a second contact point P2, a third contact point P3, a fourth contact point P4, a fifth contact point P5, a sixth contact point P6, an eighth contact point P8 and a ninth contact point P9, respectively, in a direction perpendicular to the mounting direction a, the straight lines of the contact points do not coincide, the straight line of the first contact point P1 is L21, the straight line of the second contact point P2 is L22, the straight line of the third contact point P3 is L23, the straight line of the fourth contact point P4 is P24, the straight line of the fifth contact point P5 is L25, the straight line of the sixth contact point P6 is L26, the straight line of the eighth contact point P8 is L28, the straight line of the ninth contact point P9 is L29, the terminals arranged in the staggered mode effectively reduce the requirement on the position accuracy of the contact pins when the contact pins are contacted with the terminals.
EXAMPLE III
Fig. 5 is a schematic distribution diagram of chip terminals according to a third embodiment of the present invention.
In the present embodiment, each terminal is further extended on an oval basis so that the terminal is formed to be open upstream of the terminal in the mounting direction a, and thus, when the ink cartridge 10 is mounted to an ink jet printer, the lower surface of each contact pin makes line contact with the downstream of the terminal, and the midpoints of the contact portions of the first to sixth terminals 201 to 206, the eighth terminal 208, and the ninth terminal 209 with the corresponding contact pin are P1 to P6, P8, and P9, respectively; wherein the contact points P1 and P4 form a first connecting line L31, the contact points P2 and P3 form a second connecting line L32, the contact points P5 and P9 form a third connecting line L35, and the contact points P6 and P8 form a fourth connecting line L36 in the direction perpendicular to the mounting direction a, i.e., the number of straight lines formed by the contact points of the terminals 201 and 209 and the contact pins is more than two, on one hand, the ink cartridge 10 can be stably mounted in the ink jet printer under the urging force applied by the contact pins in the same direction as the mounting direction a, and on the other hand, the offset arrangement of the respective terminals is beneficial to reducing the requirement on the position accuracy of the contact pins when the contact pins are in contact with the terminals.
In the second embodiment and the present embodiment, similarly, the seventh terminal 207 may also be an oval shape, as long as the purpose of the ink cartridge 10 receiving the urging force applied from the contact pins in the mounting direction a through the chip 20 and urging the ink cartridge 10 to be stably mounted in the inkjet printer is satisfied, for example, each terminal may also be a diamond shape, a square shape, or the like.
