Description

Technical Field

[0001] The present application relates to the field of image forming technology or printer technology, and specifically to a chip and printing consumables. Background Art

[0002] Some existing printing consumables, such as some types of printing consumables (e.g., ink cartridges), require the use of structures such as positioning handles to ensure their accurate positioning in the plumb direction / installation direction. However, in the horizontal direction, since the installation part sets a certain width margin for each installation position of the printing consumable (e.g., ink cartridge), the printing consumable (e.g., ink cartridge) may still be slightly offset in the width direction after being installed. The chip that serves as an electrical connection component on such printing consumables (e.g., ink cartridges) usually has terminals with a smaller width dimension. A slight offset of the printing consumable (e.g., ink cartridge) in the width direction may affect the electrical connection between the terminal and the printer, causing the printing consumable (e.g., ink cartridge) to be unable to be used normally.

[0003] Originally, the stylus holder on the printer side could suppress the widthwise deviation of printing consumables (such as ink cartridges) to a certain extent by elastically deforming the stylus and counteracting the chip. However, some current printer (also called printing equipment) manufacturers have upgraded the corresponding printing consumables chips from 7-contact and 9-contact to flat 5-contact chips. The upgraded chip has significantly reduced number of contacts and extremely uneven distribution while keeping the shape and size of the substrate basically unchanged, making it even more difficult to suppress the widthwise deviation of printing consumables (such as ink cartridges). Summary of the invention

[0004] In order to overcome the problems existing in the above-mentioned prior art, the main purpose of the present application is to provide a chip and printing consumables that can prevent themselves from being offset in the width direction within the installation position by means of the cooperation between the chip and the stylus holder.

[0012] In some embodiments, the external terminal is provided with a contact portion abutting against the contact pin, and projections of each of the contact portions and the external contact portion in the installation direction of the printing consumables or the chip on the printer are not in the same straight line.

[0013] In some embodiments, the inner terminal can be connected to one of a data contact pin or a ground contact pin among the contact pins through the outer contact portion.

[0057] In the prior art, the main body of the chip is a substrate, on which a memory, terminals and electronic components are provided. The substrate has a built-in printed circuit, which is used to connect the terminals and electronic components to the memory. The memory is used to store manufacturer information, ink volume information, ink cartridge category information, ink color and other information. The electronic components and the memory cooperate with each other to complete the operation of the internal program of the chip, so as to facilitate the chip to complete the corresponding work and realize the corresponding functions. When the ink cartridge is installed in the ink cartridge installation part of the printer, data transmission, confirmation, data interaction, etc. will be carried out between the storage and the printer, and the above work is completed by the connection between the terminals and the contact pins on the printer side.

[0058] Reference Figure 1 As shown, Figure 1 Schematic diagram of the ink cartridge 10 to be installed on the ink cartridge installation part 90. Printing consumables are components that need to be replaced frequently on a printer (also referred to as a printing device), and the chip 20 is a component on the printing consumables. The printing consumables may be consumable boxes, ink cartridges, toner cartridges, ribbons, etc., and the chip 20 may be a chip on the consumable box, ink cartridge, toner cartridge, or ribbon. Figure 1 The printing consumables in this article are ink cartridges, so the following text uses "ink cartridges" as an example to explain the corresponding contents.

[0059] Continue to refer to Figure 1 As shown, the ink cartridge installation part 90 is a component on the printer, which is used to carry multiple or one ink cartridge 10. The ink cartridge 10 is detachably installed in the ink cartridge installation part 90 along the installation direction P. When the ink cartridge 10 is used up, a new ink cartridge needs to be replaced. The ink cartridge 10 includes a chip 20, a handle 30, an ink outlet 40 and a box body 50. The ink cartridge installation part 90 has a stylus holder 91, an ink supply part 92, an opening 95 and a bottom wall 90a. The ink cartridge 10 is installed in the ink cartridge installation part 90 from the opening 95 along the installation direction P. Ink is stored in the box body 50, and the ink reaches the ink supply part 92 through the ink outlet 40, and then the ink supply part 92 can supply the ink to the print head, so that the ink can be used to perform the printing action. There is a terminal group on the chip 20, and the terminal group can be electrically connected with the stylus 91a of the stylus holder 91 for mutual transmission of electrical signals. The handle 30 is used to fix the ink cartridge 10 to the ink cartridge installation portion 90 to prevent the ink cartridge 10 from being separated from the ink cartridge installation portion 90 .

[0060] 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 10 is consistent with the three-dimensional rectangular coordinate system of the ink cartridge installation portion 90. The direction in which the ink cartridge 10 is installed to the ink cartridge installation portion 90 is the -Z axis direction (i.e., the installation direction P), and the direction in which the ink cartridge 10 is separated from the ink cartridge installation portion 90 is the +Z axis direction, the opening 95 is located in the +Z axis direction, the bottom wall 90a is located in the -Z axis direction, and the Y direction is the width direction of the ink cartridge. Generally, the printer is placed flat on an office desktop or a printing desktop, the opening 95 of the ink cartridge installation portion 90 is located above the gravity direction, and the bottom wall 90a is located below the gravity direction, thereby facilitating the user to install or remove the ink cartridge 10. Furthermore, the ink cartridge installation portion 90 can carry multiple or one ink cartridge 10, and has multiple or one installation positions, and four ink cartridges can store four different colors of ink, such as black, yellow, blue, and red.

[0061] Specifically, the ink cartridge mounting portion 90 is a component approximately in the shape of a rectangular parallelepiped or a cube with an opening 95, and the inner side wall and the bottom wall 90a of the ink cartridge mounting portion 90 constitute a mounting position. The stylus holder 91 is mounted on the first side wall 90c of the ink cartridge mounting portion 90, 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 perpendicular to the Y-axis and the Z-axis is the X-axis direction. Among them, the direction from the inside of the ink cartridge mounting portion 90 to the stylus holder 91 is the +X-axis direction. The +X-axis is perpendicular to the first side wall 90c. When observed 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.

[0062] Figure 2 Schematic diagram of the structure of the stylus holder 91. Figure 2As shown, the stylus holder 91 includes a base 910 and a plurality of stylus pins, which are mounted on the base 910, namely, a first stylus pin 911, a second stylus pin 912, a third stylus pin 913, a fourth stylus pin 914 and a fifth stylus pin 915. The stylus pin is a thin sheet of metal, which can play a conductive role and is not easy to wear. The base 910 has a plurality of slits, namely, a first slit 981, a second slit 982, a third slit 983, a fourth slit 984 and a fifth slit 985. Among them, each slit is respectively arranged corresponding to each stylus pin, and each slit is U-shaped, which has a slit opening in the +Z axis direction, and the plurality of stylus pins are respectively installed in each slit through the slit opening along the -Z axis direction. Specifically, the first stylus pin 911 is installed in the first slit 981 through the slit opening along the -Z axis direction; the installation method of the second stylus pin 912 to the fifth stylus pin 915 is the same, and will not be repeated here.

[0063] During the operation of the printer, one side of each of the plurality of contact pins is connected to the main circuit of the inkjet printer through the circuit inside the ink cartridge mounting portion 90, and the other side is connected to the chip 20. The structures of the first contact pin 911 to the fifth contact pin 915 are consistent, as shown in FIG. Figure 3 As shown. Taking the first contact pin 911 as an example, the first contact pin 911 includes a first portion 911a, a second portion 911b and a third portion 911c. The first portion 911a is used to connect to the chip 20, the second portion 911b is used to connect to the internal circuit of the inkjet printer, and the third portion 911c is connected to the first portion 911a and the second portion 911b.

[0064] The third part 911c is located in the +Z axis direction of the first contact pin 911, and 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. Further, the first part 911a and the second part 911b protrude from the base 910 in the X axis direction, and the base 910 is located between the first part 911a and the second part 911b. The first part 911a is closer to the installation position than the second part 911b, and the third part 911c is divided into a first vertical part 911k and a second vertical part 911j perpendicular to the X-axis direction, and a horizontal part 911h parallel to the X-axis direction; the horizontal part 911h connects the first vertical part 911k and the second vertical part 911j. The first vertical part 911k and the second vertical part 911j extend in a direction parallel to the installation direction of the ink cartridge to the ink cartridge installation part (i.e., the Z-axis direction). The first vertical part 911k is closer to the installation position than the second vertical part 911j, the end of the first vertical part 911k is connected to the first part 911a, and the end of the second vertical part 911j is connected to the second part 911b, and the horizontal part 911h or the first vertical part 911k and the second vertical part 911j are fixed to the first slit 981 in the +Z-axis direction. The first part 911a is located at the end of the first contact pin 911. The first part 911a of the first contact pin 911 is electrically connected to the chip 20 to form a contact area; the second part 911b is connected to the circuit in the inkjet printer. The first part 911a includes a first surface portion 911a1, a second surface portion 911a2, a third surface portion 911a3 and a fourth surface portion 911a4, wherein the third surface portion 911a3 and the fourth surface portion 911a4 are arranged opposite to each other along the Y direction, and the first surface portion 911a1 and the second surface portion 911a2 enclose an area to form a ridge area. The first vertical portion 911k is a vertical area, the second portion 911b is another ridge area, and the second vertical portion 911j is another vertical area. The second contact pin 912 to the fifth contact pin 915 have the same arrangement and structure as the first contact pin 911, and their detailed illustrations and explanations will not be provided here.

[0065] See also Figure 1 , 4As shown, the chip 20 used in the ink cartridge 10 includes a substrate 21 a , and the substrate 21 a is provided with five terminals 23 e on an outer plane 22 d away from the cartridge body 50 .

[0066] Among them, the first terminal 231, the second terminal 232, the third terminal 233 and the fourth terminal 234 are located on the -Y side of the external surface, the fifth terminal 235 is located on the +Y side of the external surface, the contact parts of the second terminal, the third terminal and the fifth terminal are located on the straight line L1 parallel to the Y axis, the contact parts of the first terminal and the fourth terminal are located on the straight line L2 parallel to the Y axis, and the straight line L2 is located on the +Z side of the straight line L1. In the accompanying drawings, the contact parts of the corresponding terminals are indicated by the shaded area in the middle of the terminals.

[0067] The first terminal 231 to the fifth terminal 235 are all arranged on the outer plane 22d, and the end faces of the five terminals are equidistant from the outer plane 22d, so the contact portions of the first terminal 231 to the fifth terminal 235 are in the same plane. In addition, the sizes of the five terminals are relatively close, and their lengths in the Z-axis direction are significantly greater than their lengths in the Y-axis direction. A small deviation of the ink cartridge 10 in the Y direction may affect the electrical connection between the terminal and the printer, causing the ink cartridge 10 to be unable to be used normally. The first terminal 231 to the fourth terminal 234 are all on the -Y side of the outer plane 22d and are relatively close in position, and the fifth terminal 235 is located on the +Y side of the outer plane 22d and is far away from the first terminal 231 to the fourth terminal 234. In the installed state, the contact pins in contact with the chip 20 undergo elastic deformation, and when the ink cartridge 10 as a whole has a tendency to move in the Y direction, static friction can be generated to suppress the movement of the ink cartridge 10 in the Y direction. However, there are only five related contact pins (i.e., the first contact pin 911 to the fifth contact pin 915 mentioned above), and the contact parts of the first terminal 231 to the fifth terminal 235 are all in the same plane. Therefore, the deformation amplitudes of the five contact pins are basically the same and the static friction that can be provided is relatively small. The number of terminals is small and their distribution is extremely uneven, which is not enough to suppress the displacement of the chip 20 / ink cartridge 10 in the Y direction at the installation position.

[0068] Embodiment 1 The chips involved in the following embodiments are all matched with the above-mentioned contact pin holder 91, and the functions of the corresponding terminals are consistent with the above-mentioned first terminal 231 to fifth terminal 235. The specific implementation of this embodiment is briefly described below: See also Figures 5 to 8The ink cartridge 400 includes a box body 410 and a chip 300. The box body 410 is provided with a receiving portion 411 that cooperates with the chip 300. The chip 300 includes a substrate 310. The substrate 310 has a surface with the largest area as a front surface 310a. The substrate 310 is provided with at least one external terminal 320 on the front surface 310a. The external terminal 320 is used to abut against the contact pin. The surface of the substrate 310 parallel to the front surface 310a is a rear surface 310b. The rear surface 310b is provided with at least one internal terminal 330. The internal terminal 330 is not used to abut against the contact pin. The ink cartridge 400 / chip 300 also includes a second component (the second component in this embodiment is a conductive member 500) for connecting the corresponding contact pin on the printer side to the internal terminal 330. In some embodiments, the conductive member can also be a chip bracket. The conductive member 500 is located between the receiving portion 411 and the substrate 310. The conductive member 500 includes a contact portion 510 that contacts the inner terminal 330 and an outer contact portion 520 that matches the corresponding contact pin on the printer side. The conductive member 500 has an extension portion 530 that does not overlap with the substrate 310. The outer contact portion 520 is located on the side of the extension portion 530 that faces the rear surface 310b. The conductive member 500 is electrically connected to the chip 300, so the conductive member 500 can be regarded as a part of the chip 300. The conductive member 500 can also be regarded as a part of the box body 410. For example, the conductive member 500 is located between the receiving portion 411 and the substrate 310 and the conductive member 500 serves as a chip bracket for fixing or contacting at least a part of the substrate 310.

[0069] In this embodiment, the inner terminal 330 is disposed on the rear surface 310b, and the conductive member 500 is welded on the rear surface 310b, so that at least a portion of the conductive member 500 is located on the -X axis side of the rear surface 310b. It can be understood that in other embodiments, the inner terminal 330 can also be disposed on the front surface 310a, and the conductive member 500 is welded on the front surface 310a, so that at least a portion of the conductive member 500 is located on the +X axis side of the front surface. Since the external contact portion 520 is located outside the conductive member 500 and has a certain surface difference with the external terminal 320, the relative movement between the ink cartridge 400 / chip 300 and the contact pin corresponding to the external contact portion 520 in the width direction (i.e., the Y direction) can be limited by optimizing the shape and size of the substrate 310. Since a second component is provided and the second component is provided with an extension portion which does not overlap with the substrate, when the chip is in working state, the contact pin abuts against the substrate and the extension portion respectively. At this time, the provision of the extension portion increases the conductive area that can be contacted by the contact pin, thereby ensuring the function of the chip to the greatest extent; or a gap or blockage can be formed between the terminals to reduce the occurrence of short circuit; or the contact portion between the contact pin and the substrate and the contact portion between the contact pin and the extension portion have a certain surface difference, thereby limiting the displacement of the printing consumables along their own width direction, thereby improving the stability of the connection between the chip and the contact pin holder, and reducing the risk of short circuit between the terminals of the chip during use; at the same time, the different deformation amplitudes / extrusion forces between the contact pins after the chip or printing consumables are installed improve the stability and reliability of the contact.

[0070] In this embodiment, the chip 300 further includes a memory 340 and an electrical component 350 protruding from the rear surface 310b, and the memory 340 is electrically connected to the electrical component 350, the external terminal 320 and the internal terminal 330. In specific implementation, the conductive member 500 can be disposed on the chip 300 (the conductive member 500 is regarded as a part of the chip 300), or on the box body 410 (the conductive member 500 is regarded as a part of the box body 410). The conductive member 500 can be made of conventional conductive materials, such as metal, conductive silicone, conductive plastic, conductive ceramic, etc., and only needs to conduct the corresponding contact pin with the internal terminal 330. On the other hand, the second component is made of metal, conductive plastic, conductive silicone or conductive ceramic.

[0071] Figures 5 to 8What is shown is the first embodiment of the present application. In this embodiment, a conductive sheet 540 fixedly arranged on the chip 300 is used as the conductive member 500. A notch portion 311 penetrating the front surface 310a and the rear surface 310b is provided on the +Y side of the -Z end of the substrate 310. The internal terminal 330 is located at the edge of the notch portion 311. The conductive sheet 540 uses the portion overlapping with the internal terminal 330 as the abutment portion 510, and uses the portion located in the notch portion 311 as the extension portion 530, so that the external contact portion 520 is exposed from the notch portion 311, so that the contact pin can extend into the notch portion 311 and abut against the external contact portion 520. Figure 7 The partial outlines of the notch 311 and the inner terminal 330 are indicated by dotted lines. Figure 8 The dotted line shaded area indicates the abutment portion 510, and the portion of the conductive sheet 540 other than the shaded area is the extension portion 530. An inner terminal 330 is reserved on the -Y side of the +Z end of the rear surface 310b or on the -Y and +Z sides of the rear surface 310b, and the shape and size of the conductive member 500 will change slightly, such as the size of the conductive member 500 becomes larger to contact the inner terminal 330, and the length of the conductive member 500 in the Y-axis direction is greater than half the length of the substrate 310; the conductive member 500 abuts against the inner terminal 330 and has an extension portion 530. This structure makes the size of the conductive member 500 larger and easier to install on the chip 300 or the box body 410.

[0072] The receiving portion 411 also has a positioning post 414. A positioning portion 312 is provided on the edge of the substrate to cooperate with the positioning post 414. The positioning portion 312 passes through the front surface 310a and the rear surface 310b. In this embodiment, three positioning portions 312 are provided on the +Z side and ±Y side edges of the substrate 310, and the receiving portion 411 includes three corresponding positioning posts 414.

[0073] In this embodiment, the first terminal 360, the second terminal 370, the third terminal 380 and the fourth terminal 390 are used as the external terminals 320, and each terminal has a first contact portion 360a, a second contact portion 370a, a third contact portion 380a and a fourth contact portion 390a, respectively. The line S2 connecting the first contact portion 360a and the fourth contact portion 390a is parallel to the line S1 connecting the second contact portion 370a and the fourth contact portion 380a. Considering that the external terminals 320 are all arranged by partial copper cladding process and only slightly protrude from the front surface 310a, S1 and S2 can be regarded as straight lines on the front surface 310a. Furthermore, the contact portion of each external terminal 320 and the projection of the external contact portion 520 in the installation direction of the printing consumables or the chip to the printer are not in the same straight line.

[0074] The functions of each terminal are as follows: The first terminal 131 (data terminal): is used to send or receive a data signal, and is also used to detect a short circuit between the first terminal 231 and at least one of the second terminal 232 , the third terminal 233 , or the fourth terminal 234 .

[0075] The second terminal 132 (clock terminal): is used to receive a clock signal.

[0076] The third terminal 133 (power terminal): is used to receive a power potential different from the ground potential (such as 3.6V or 3.3V), and provides power for the memory (not shown in the figure) through this terminal.

[0077] The fourth terminal 134 (reset terminal): is used to reset the internal data of the chip.

[0078] The extension portion 530 / the external contact portion 520 : is used to receive the ground potential.

[0079] In this embodiment, the conductive sheet 540 serves as the fifth terminal. The conductive sheet 540 is a flat component attached to the rear surface 310b. Therefore, there is a certain surface difference between the external contact portion 520 and the front surface 310a. In the installed state, the deformation amplitude of the contact pin corresponding to the external contact portion 520 on the printer side in the X direction is different from that of the contact pin corresponding to the four external terminals 320, and the projection of the external contact portion 520 on the front surface 310a is not on S1, but is located on the +Z side of S1.

[0080] The substrate 310 has a left side surface 310g, a right side surface 310d, a top surface 310e and a bottom surface 310f. The notch 311 is configured as a through groove, which not only penetrates the front surface 310a and the rear surface 310b, but also penetrates the top surface 310e and the bottom surface 310f, that is, the notch 311 is a through groove in the Z-axis direction. In the Z-axis direction, the size of the conductive member 500 is substantially equivalent to that of the substrate 310. This structure makes the size of the conductive member 500 larger and easier to install on the chip 300 or the box body 410.

[0081] When the conductive member 500 is disposed on the chip 300 (the conductive member 500 is regarded as a part of the chip 300 ), the conductive member 500 is disposed on the substrate 310 by welding or conductive adhesive bonding, and then the chip 300 is mounted on the receiving portion 411 of the box body 410 .

[0082] When the conductive member 500 is disposed on the box body 410 (the conductive member 500 is regarded as a part of the box body 410), the conductive member 500 is first installed at the receiving portion 411, and then the chip 300 is installed at the receiving portion 411 and at least a part of it is fixed or abutted against the conductive member 500. When the notch portion 311 passes through the front surface 310a and the rear surface 310b, and passes through the top surface 310e and the bottom surface 310f, it is more convenient to install the conductive member 500 on the box body 410 during the production process. The conductive member 500 can be configured as follows Figure 7 or Figure 8 The flat plate shape shown may also be set to a shape with a curved surface, or may be set to a shape formed by folding a conductive material, such as a folded metal sheet. The conductive member 500 / second component may be fixedly arranged (such as Figure 8 As shown), it can also be arranged in a way with a certain elasticity. Specifically, the extension part can be deformed / moved in the direction from the front surface 310a to the rear surface 310b, for example: the metal sheet is folded into a partially suspended form, or a lever form with one end of the metal sheet suspended, or a metal sheet is bent. When the contact pin contacts the conductive member 500 / the second component, the extension part 530 / the external contact part 520 will move toward the -X axis side / in the direction from the front surface 310a to the rear surface 310b because there is a gap 570 at the suspended position. When the conductive member 500 is folded into a partially suspended form or a lever form with one end of the metal sheet suspended, the external contact part 520 is arranged on the suspended side; when the contact pin contacts the conductive member 500 / the second component, the extension part 530 / the external contact part 520 will move toward the -X axis side / in the direction from the front surface 310a to the rear surface 310b. When the conductive member 500 is formed by bending a metal sheet, the external contact portion 520 is arranged at the vertex of the bend. The conductive member 500 is arranged in a manner having a certain elasticity. When the contact pin contacts the conductive member 500 / the second component, a portion of the conductive member 500 / the second component (specifically, the extension portion) is deformed toward the -X axis side / in the direction from the front surface 310a to the rear surface 310b, and the external contact portion 520 will also move with the deformation of the conductive member 500 / the second component. This solution can alleviate the force of the contact pin on the conductive member 500, thereby making the electrical connection between the conductive member 500 and the contact pin more stable. The reference numeral 560 in the figure is a rotating shaft.

[0083] Optionally, the second component and the box body 410 can be made into an integral or split type during the production process. When the second component and the box body 410 are integral, the second component can be made with the box body 410 by "double-color injection molding". For example, when the second component is made of conductive plastic, when the box body 410 is produced, one barrel is a conductive raw material, and the other barrel is a common raw material. After plasticization, they are injected into the mold one after another, and finally there are two different materials on one injection molded part, which can meet the conductivity requirements of the second component; for example, when the second component is made of metal, the second component can be made first and then put into the injection mold. During the injection molding process, the metal will be embedded in the box body 410 in an undetachable manner, which can meet the conductivity requirements of the second component. Optionally, when the second component and the box body 410 are integral, the second component is a part of the box body 410, and the second component and the box body 410 are both made of conductive materials.

[0084] Since the four external terminals 320 are all arranged close to the -Y side of the substrate 310, the conductive sheet 540 is arranged close to the +Y side of the substrate 310, which is far away from the four external terminals 320, and there is a certain surface difference between the contact part of the external contact 520 and the contact part of the external terminal 320, it is not easy for ink droplets or conductive foreign matter to conduct the contact part of the external contact 520 and the external terminal 320, that is, the chip 300 is not easily affected by external factors and short-circuited in the installed state. In addition, it is easy to think that the conductive sheet 540 can also be set to the -Y side of the substrate 310 to replace the first terminal and / or the second terminal, and the rear surface 310b is on the -Y side of the +Z end or the rear surface 310b is on the -Y and +Z sides. An internal terminal 330 is reserved, so that the substrate 310 is convenient to set a notch next to the internal terminal 330 and then introduce the conductive sheet to replace the first terminal.

[0085] When the ink cartridge 400 is offset in the -Y direction in the ink cartridge mounting portion 90, the contact pin corresponding to the external contact portion 520 can abut against the -Y side of the notch portion 311 of the substrate 310 to limit the ink cartridge 400 from further offset in the -Y direction. In addition, it is easy to imagine that the notch portion 311 can also be set in the form of a through groove, that is, the notch portion 311 does not extend to the +Y side edge of the substrate 310 in the Y direction, so that the offset of the ink cartridge 400 in the +Y direction can be limited by the cooperation between the contact pin corresponding to the external contact portion 520 and the substrate 310. This structure can limit the offset of the ink cartridge 400 / chip 300 in the direction of its own width, and improve the connection stability between the ink cartridge 400 / chip 300 and the contact pin holder 91. In addition, since the external terminal 320 and the external contact portion are respectively arranged on the substrate and the conductive sheet, the risk of short circuit between the terminals of the ink cartridge 400 / chip 300 during use is low.

[0086] Embodiment 2 Figures 9 to 11The second embodiment of the present application is shown. The difference between this embodiment and the first embodiment is that the second component of this embodiment is a conductive member 500. In this embodiment, a conductive block 550 with elasticity fixedly arranged on the receiving portion 411 is used as the conductive member 500. The receiving portion 411 has a supporting surface 412 that is in contact with the rear surface 310b. A recessed portion 413 is provided on the supporting surface 412. The recessed portion 413 is used to accommodate the memory 340 and the electrical component 350. The conductive block 550 is also located in the recessed portion 413. The conductive block 550 uses the portion in contact with the inner terminal 330 as the abutting portion 510, and the portion protruding from the +Y side edge of the substrate 310 as the extension portion 530. In a specific implementation, a retaining structure (such as a protrusion or a frame-like structure) for limiting the conductive block 550 can be set in the recessed portion 413, and the elastic deformation of the conductive block 550 can be used to strengthen the coordination between the conductive block 550 and the retaining structure and the chip 300. The conductive block 550 in this embodiment is made of conductive silicone.

[0087] Furthermore, in order to facilitate the connection between the corresponding contact pin on the printer side and the inner terminal 330 (not shown in the figure), the conductive block 550 is provided with a connecting ridge 551 on the side facing the rear surface 310b, and the end of the connecting ridge 551 abutting against the inner terminal 330 serves as the abutting portion 510, and the end of the connecting ridge 551 extending to the extension portion 530 serves as the outer contact portion 520. The connecting ridge 551 can play a role similar to that of a wire, and the electrical signal between the corresponding contact pin on the printer side and the inner terminal 330 can be transmitted only through the connecting ridge 551, and will not pass through other parts of the conductive block 550, which helps to improve the signal transmission efficiency.

[0088] The installation direction of the ink cartridge 400 is the -Z direction (same as the aforementioned P direction). When the ink cartridge 400 is offset in the -Y direction in the ink cartridge installation portion 90, the contact pin corresponding to the external contact portion 520 can abut against the -Y side of the substrate 310 to limit the ink cartridge 400 from further offset in the -Y direction. At the same time, it is easy to imagine that the substrate 310 can also introduce a notch portion 311 with reference to the previous embodiment, and even set the notch portion 311 to be a through groove shape, so as to further limit the offset of the ink cartridge 400 in the +Y direction. In addition, considering that the external contact portion 520 is located outside the substrate 310 and there is a certain surface difference between the contact portion with the four external terminals 320, it is not easy for ink droplets or conductive foreign matter to conduct the contact portion between the external contact portion 520 and the external terminal 320, that is, the chip 300 is not easily affected by external factors and short-circuited in the installed state. In addition, the projection of the external contact portion 520 on the front surface 310a is not on the connecting line of the second contact portion 370a and the third contact portion 380a. It is also easy to imagine that the conductive block 550 can also be provided on the -Y side of the substrate 310 to replace the first terminal and / or the second terminal.

[0089] Embodiment 3 Reference Fig.12 , 13 As shown, in this embodiment, the chip 4 has a substrate, and the substrate has four non-grounding terminals 5a, which are arranged on the front surface of the chip 4, namely a data terminal (equivalent to the first terminal 360 of the first embodiment), a reset terminal (equivalent to the fourth terminal 390 of the first embodiment), a clock terminal (equivalent to the second terminal 370 of the first embodiment) and a power terminal (equivalent to the third terminal 380 of the first embodiment), and the positions of the four non-grounding terminals on the front surface of the chip 4 are defined as non-grounding terminal setting areas. The chip 4 also has a grounding inner terminal (not shown in the figure) (equivalent to the inner terminal 330 in the first embodiment), which is arranged on the rear surface of the chip 4. Preferably, the grounding inner terminal (equivalent to the inner terminal 330 in the first embodiment) can be arranged at the corresponding position and around the non-grounding terminal setting area on the rear surface of the chip 4.

[0090] A contact pin holder 91 (also referred to as a contact pin portion) is provided on the inner wall of the ink cartridge mounting portion 90 (equivalent to the first side wall 90c of the first embodiment), and contact pins are provided on the contact pin holder 91. There are five contact pins, namely a first contact pin 911, a second contact pin 92, a third contact pin 913, a fourth contact pin 914, and a fifth contact pin 915, four of which correspond to the non-ground terminals 5a on the chip 4, namely a data contact pin (equivalent to the first contact pin 911), a reset contact pin (equivalent to the fourth contact pin 914), a clock contact pin (equivalent to the second contact pin 92), and a power contact pin (equivalent to the third contact pin 913); the data contact pin (equivalent to the first contact pin 911), the reset contact pin (equivalent to the fourth contact pin 914), the clock contact pin (equivalent to the second contact pin 92), and the power contact pin (equivalent to the third contact pin 913) are collectively referred to as a non-ground contact pin 22e, and the other one is a ground contact pin 21e (equivalent to the fifth contact pin 915).

[0091] When the ink cartridge 3 is installed in the ink cartridge installation part 90 along the installation direction, the front surface of the ink cartridge 3 is opposite to the inner wall of the ink cartridge installation part 90 where the contact pin is located (equivalent to the first side wall 90c of the first embodiment), so that the four non-grounded terminals 5a on the chip 4 respectively abut against four of the non-grounded contact pins 22e, and the two form contact one by one, thereby forming an electrical connection between the chip 4 and the image forming device. In this embodiment, "front" refers to the direction from the ink cartridge to the contact pin holder 91, and "rear" refers to the direction from the contact pin holder 91 to the ink cartridge. "Front surface" refers to the surface facing the contact pin holder 91, and "rear surface" refers to the surface facing away from the contact pin holder 91.

[0092] In the prior art, the ground contact pin 21e (equivalent to the fifth contact pin 915) originally directly contacts the chip to form an electrical connection. In the present embodiment, the ground contact pin 21e (equivalent to the fifth contact pin 915) does not directly contact the chip, but establishes an electrical connection between the two through the chip holder 6 (equivalent to the second component in the first embodiment, that is, the second component in the present embodiment is the chip holder 6) and forms an external contact portion (also called a ground contact portion) on the chip holder 6, and the chip holder 6 contacts the ground inner terminal of the chip (equivalent to the inner terminal 330 in the first embodiment) and the ground contact pin 21e (equivalent to the fifth contact pin 915), that is, the path of the electrical connection is changed from the path in the prior art: the ground terminal on the chip-the ground contact pin 21e, to the path in the present embodiment: the ground inner terminal of the chip-the chip holder 6-the ground contact pin 21e. The ground contact pin 21e of the present embodiment contacts the conductive part of the chip holder 6, and the conductive part of the chip holder 6 contacts the ground inner terminal of the chip. In this embodiment, the chip holder 6 can be made entirely of conductive materials, such as metal, conductive plastic or conductive silicone. In other embodiments, the chip holder 6 can be partially made of conductive materials, as long as the electrical connection between the chip holder 6 and the ground contact pin 21e and the ground inner terminal of the chip can be achieved. The chip holder 6 can partially fix / abut the substrate of the chip. The chip holder 6 can also be regarded as a part of the chip. The chip holder 6 also has an extension portion. When the chip holder 6 is made entirely of conductive materials, the chip holder 6 (equivalent to the second component in the first embodiment) can be regarded as the conductive member 500 of the first embodiment.

[0093] The chip holder 6 has a front surface of the stylus holder 91 facing the ink cartridge mounting portion 90, and a rear surface facing away from the stylus holder 91. The chip 4 is mounted on the chip holder 6 in a manner that its rear surface is in close contact with the front surface of the chip holder 6. The mounting method may be pasting, welding, or clamping, etc. In this embodiment, a first positioning hole 41 (equivalent to the positioning portion 312 of the first embodiment) is provided on the chip 4, and a first protrusion 61a (equivalent to the positioning column 414 of the first embodiment) is provided on the front surface of the chip holder 6. The first positioning hole 41 and the first protrusion 61a are used to realize the clamping fixation of the chip 4 and the chip holder 6. In other embodiments, the chip 4 may be fixed without the first positioning hole 41, for example, by pasting, etc., see Fig.18 Optionally, the first protrusion 61a (equivalent to the positioning column 414 in the first embodiment) can be provided on the box body, and the chip holder 6 is provided between the chip 4 and the box body in an abutting / clamping manner.

[0094] After installation, the grounding inner terminal on the rear surface of the chip 4 contacts and forms an electrical connection with the front surface of the chip holder 6. In other embodiments, the grounding inner terminal may also be arranged at other positions of the chip 4, such as the side, and the chip holder 6 may be provided with a structure capable of contacting the grounding inner terminal, such as a protruding structure, or the grounding inner terminal may be electrically connected to the chip holder 6 by means of conductive adhesive bonding or welding, as long as the electrical connection between the grounding inner terminal and the chip holder 6 can be achieved.

[0095] The chip 4 partially covers the front surface of the chip holder 6, so that the chip holder 6 leaves a reserved area 71 (equivalent to the extension part 530 of the first embodiment) not covered by the chip 4. The reserved area 71 is used to contact the grounding contact pin 21e (equivalent to the fifth contact pin 915) of the ink cartridge installation part 90. Specifically, the contact area between the reserved area 71 and the grounding contact pin 21e is the outer contact part, so as to realize the electrical connection between the chip holder 6 and the grounding contact pin 21e. This way of forming contact with the grounding contact pin 21e through the chip holder 6 makes the grounding contact pin 21e no longer limited to the contact area of ​​the grounding terminal in the prior art, but can be flexibly set in a variety of ways, thereby increasing the conductive area in contact with the grounding contact pin 21e. Even when the ink cartridge is not installed properly or the position is deviated, the grounding function can be guaranteed to the greatest extent, so as to prevent personal electric shock accidents and ensure the normal operation of the printer.

[0096] There are many ways to set the reserved area 71. For example, the chip 4 may be provided with a through hole or a notch at a position corresponding to the ground terminal of the prior art, so that the chip holder 6 leaves a reserved area 71 not covered by the chip 4 at this position. Figure 12-13 A corner notch 43 (equivalent to the notch portion 311 of the first embodiment) is provided at a position of the chip 4 corresponding to the ground terminal of the prior art, thereby forming a reserved area 71 to contact the ground contact pin 21e to achieve grounding.

[0097] See also Figure 14-15 When all the contact points of all the terminals of the chip 4 are projected along the first imaginary line C1 to the second imaginary line C2, due to the certain thickness of the chip 4, there is a certain height difference between the surface of the non-grounding terminal 5a (i.e., the front surface of the chip 4) and the front surface of the chip bracket 6. The projection points of the contact points of the four non-grounding terminals 5a and the four non-grounding contact pins 22e fall on the second imaginary line C2, and the projection points of the contact points of the reserved area 71 and the grounding contact pin 21e (equivalent to the external contact part of the first embodiment) fall outside the second imaginary line C2. The projection points of the contact points of the grounding contact pin 21e form a certain distance L with the second imaginary line C2 in the front-to-back direction (this distance L is the thickness of the chip 4). See Figure 16-17In some variant implementations, the chip 4 of this embodiment can be formed by cutting off one side of the chip in the prior art where the ground terminal is originally set. The resulting reserved area is larger and more conducive to the contact of the ground contact pin 21e.

[0098] Embodiment 4 See also Figures 19 to 21 The chip 100 provided in this embodiment includes a substrate 110, and the substrate 110 includes an outer plate 111 (equivalent to the substrate 310 of the first embodiment) and an inner plate 112 (equivalent to the second component / conductive member 500 of the first embodiment) stacked, the outer plate 111 is located on the +X side of the inner plate 112, the +X end surface of the outer plate 111 is a first external connection surface 113 (equivalent to the front surface 310a of the first embodiment), the -X end surface of the outer plate 111 is an internal connection surface 114 (equivalent to the rear surface 310b of the first embodiment), and the first external connection surface 113 is protruded on the -Y side to provide a first terminal 1 30b (equivalent to the first terminal 360 of the first embodiment), the second terminal 130c (equivalent to the second terminal 370 of the first embodiment), the third terminal 140 (equivalent to the third terminal 380 of the first embodiment) and the fourth terminal 150 (equivalent to the fourth terminal 390 of the first embodiment), the outer plate 111 is provided with a notch 115 (equivalent to the notch 311 of the first embodiment) on the +Y side, and a memory 170 is protrudingly provided on the inner surface 114, and the memory 170 is electrically connected to the first terminal 130b, the second terminal 130c, the third terminal 140 and the fourth terminal 150. The +X end surface of the inner plate 112 is a second external surface 116 (equivalent to the surface on the +X axis side of the second component / conductive member 500 of the first embodiment), and the second external surface 116 is partially in contact with the inner surface 114. A fifth terminal 160 (equivalent to the extension portion 530 of the first embodiment) is protruded from the second external connection surface 116 in the area overlapping with the notch portion 115, and the +X-direction end surface of the fifth terminal 160 is located at the -X side of the first external connection surface 113. In this solution, the inner plate 112 (equivalent to the second component / conductive member 500 of the first embodiment) is regarded as a part of the chip 100.

[0099] A connecting terminal 180 electrically connected to the fifth terminal 160 is provided on the second external connection surface 116 in an area overlapping with the internal connection surface 114. An internal terminal (not shown in the figure, equivalent to the internal terminal 330 of the first embodiment) in contact with the connecting terminal 180 is provided on the internal connection surface 114. The internal terminal is electrically connected to the memory 170, so that the fifth terminal 160 is connected to the memory 170 through the connection between the connecting terminal 180 and the internal terminal.

[0100] Since the first terminal 130b to the fourth terminal 150 are all arranged on the first external surface 113, and the +X end surface of the fifth terminal 160 is located on the -X side of the first external surface 113, it can be ensured that the contact portion of the first terminal 130b to the fourth terminal 150 and the contact portion of the fifth terminal 160 are not in the same plane. In the installed state, compared with the single substrate chip, the contact pins corresponding to the first terminal 130b to the fourth terminal 150 have a larger deformation amplitude, so that they can provide greater friction in the Y direction. The notch portion 115 can act with the contact pin corresponding to the fifth terminal 160 to limit the -Y movement of the chip 100, thereby limiting the corresponding ink cartridge from moving along the +Y direction as a whole.

[0101] Although the contact line between the first terminal 130b and the fourth terminal 150 is parallel to the contact line between the second terminal 130c and the third terminal 140, since the deformation amplitude of the contact pin corresponding to the fifth terminal 160 is smaller than the deformation amplitudes of the contact pins corresponding to the other four terminals, the contact portion of the fifth terminal 160 is not on the same straight line as the contact portions of the second terminal 130c and the third terminal 140. Therefore, the fifth terminal 160, the second terminal 130c and the third terminal 140 cannot be considered to be arranged in the same row.

[0102] An avoidance portion 117 is provided on the inner plate 112 in an area overlapping with the storage device 170, a first alignment hole 118 (equivalent to the positioning portion 312 of the first embodiment) is provided on the outer plate 111, and a second alignment hole 119 is provided on the inner plate 112 in an area corresponding to the first alignment hole 118. The introduction of the avoidance portion 117 and the two alignment holes can strengthen the fit between the outer plate 111 and the inner plate 112, and improve the accuracy of the alignment assembly between the outer plate 111 and the inner plate 112 and the installation to the ink cartridge.

[0103] See also Figures 22 to 24 , Figures 22 to 24Another implementation form of the present embodiment is shown, which has the same technical effect as the aforementioned implementation form. The difference between it and the aforementioned implementation form is that the notch 115 is set on the -Y side of the outer plate 111, the first terminal 130b is set on the inner plate 112, the second terminal 130c to the fifth terminal 160 are all set on the outer plate 111, the second terminal 130c to the fifth terminal 160 are all electrically connected to the memory 170, the first terminal 130b is connected to the memory 170 through the connecting terminal 180 and the inner terminal, the outer plate 111 is provided with a first alignment hole 118, and the inner plate 112 is not provided with a corresponding alignment hole. Since the deformation amplitude of the contact pin corresponding to the first terminal 130b is smaller than the deformation amplitudes of the contact pins corresponding to the other four terminals, although the contact parts of the second terminal 130c, the third terminal 130c and the fifth terminal 160 are on an imaginary line L3 parallel to the Y-axis, the contact part connection line between the first terminal 130b and the second terminal 130c and the imaginary line L3 and the Y-axis are all skewed and not parallel, so the first terminal 130b and the second terminal 130c cannot be considered to be arranged in the same row.

[0104] Embodiment 5 Reference Fig.25 As shown, the ink cartridge 10 of the present application includes a box body 50, which is surrounded by multiple side surfaces to form a roughly cubic shape, and the end surface in the plumb direction is set as the bottom surface 110a, and the bottom surface 110a is provided with an ink outlet 40, the front 107 and the rear (not shown in the figure) are arranged opposite to each other and perpendicular to the bottom surface 110a, and the upper part of the front 107 is provided with a handle 30, and the lower part of the handle 30 is also provided with a receiving portion 411, and the receiving portion 411 is used to install the chip 20 (such as Fig.26 ) and an independent electrical connection portion 80 (as shown Fig. 27 As shown in the figure (equivalent to the second component / conductive member 500 of the first embodiment), the electrical connection portion 80 is provided with a fifth terminal 205 connected to the stylus holder 91 of the printer, which is equivalent to the extension portion 530 of the first embodiment). The chip 20 includes a substrate 120, and the substrate 120 is provided with a plurality of terminals on the surface facing away from the box body 50. The plurality of terminals are arranged in the following manner: the first terminal 201a and the fourth terminal 204a are arranged in the first row, the second terminal 202a and the third terminal 203a are arranged in the second row, and the projections of the contact portions of the first terminal 201a, the second terminal 202a, the third terminal 203a, and the fourth terminal 204a in the installation direction do not overlap.

[0105] The first terminal 201a to the fourth terminal 204a are respectively a data terminal, a clock terminal, a power terminal and a reset terminal. The fifth terminal 205a arranged on the electrical connection part 80 is a ground terminal. The fifth terminal 205a is used to receive the ground potential and has a fifth terminal contact part connected to the printer contact pin. The contact parts of the first terminal 201a, the second terminal 202a, the third terminal 203a, the fourth terminal 204a and the fifth terminal 205a are adapted to be connected with a plurality of contact pins on the contact pin holder 91.

[0106] Of course, the electrical connection part 80 can be of any shape, such as a cube, a cylinder, etc., as long as the terminal contact part can be set on the electrical connection part 80. The shape of the electrical connection part is not limited here. In addition, the electrical connection part 80 and the receiving part 411 can be connected together by pasting, gluing, bonding, and snapping, and then the chip 20 is installed on the receiving part 411. The chip 20 can be fixed on the receiving part 411 by matching the recess (equivalent to the positioning part 312 of the first embodiment) with the protrusion (equivalent to the positioning column 414 of the first embodiment), or it can be fixed on the receiving part 411 by pasting or the like; the above method only needs to ensure that the substrate 120 and the electrical connection part 80 are insulated and compatible with the contact pin holder 91.

[0107] It is understandable that there may be a distance in space between the substrate 120 of the chip 20 and the electrical connection part 80, that is, the two may not be directly connected, for example, there may be a gap or height difference between the two (that is, there is no contact and no connection between the two), and the height difference means that the ends in the direction from the rear surface to the front surface 107 are not flush, and the deformation amplitude of the corresponding stylus in the installed state is inconsistent, and it is only necessary to meet the connection with the stylus holder 91. For example, during installation, the substrate 120 and the electrical connection part 80 are separately installed on the receiving part 411. Among them, the substrate 120 and the electrical connection part 80 can be arranged vertically, parallel or inclined, as long as the two are insulated from each other and compatible with the stylus holder 91 on the printer.

[0108] Another feasible implementation is that a conductive device is also provided on the receiving portion 411, and the conductive device (not shown in the figure) is used to connect the electrical connection portion 80 with the chip, and a fifth terminal 205a is provided on the electrical connection portion 80, and the fifth terminal 205a is connected to the wafer on the back side of the chip 20 (i.e., the side of the substrate 120 facing the box body 50) through the conductive device to achieve electrical connection (the electrical connection of the wafer, the internal terminal, the conductive device, and the electrical connection portion 80 is achieved through the internal terminal 330 of the first embodiment), and the chip 20 is also placed on the receiving portion 411, and the substrate 120 of the chip 20 is provided with a first terminal 201a, a second terminal 202a, a third terminal 203a, and a fourth terminal 204a. Of course, the arrangement of the terminals on the chip 20 and the terminals on the electrical connection portion 80 needs to meet the adaption connection of the stylus holder 91 on the printer.

[0109] Embodiment 6 See also Fig.28 The ink cartridge corresponding to this embodiment is basically the same as that of the fifth embodiment, and the corresponding structures use the same reference numerals, the only difference being that this embodiment uses a chip holder 70 as a receiving portion 411 to mount the chip 20 and the electrical connection portion 80. The ink cartridge 10 provided in this embodiment includes a box body 50, a handle 30 is provided on the upper portion of the front 107 of the box body 50, and a chip holder 70 is provided on the lower portion (the chip holder 70 here is not conductive), as shown in FIG. Fig.28 As shown, the chip holder 70 is provided with an electrical connection part 80, the fifth terminal 205a is provided on the electrical connection part 80, and the first terminal 201a, the second terminal 202a, the third terminal 203a and the fourth terminal 204a are provided on the substrate 120. When the chip 20 is mounted on the chip holder 70, the electrical connection part 80 and the chip 20 can be attached to each other. It can be understood that the electrical connection part 80 can be of any shape, and the substrate 120 and the electrical connection part 80 are separately fixed on the chip holder 70, but the substrate 120 and the electrical connection part 80 are insulated from each other, that is, there is no electrical connection between the two, so that the possibility of short circuit between the terminal on the substrate 120 and the fifth terminal 205a on the electrical connection part 80 can be greatly reduced; those skilled in the art can also understand that there can be a distance between the substrate 120 and the electrical connection part 80 in space, that is, there can be no direct connection between the two, for example, there can be a gap or height difference between the two (that is, there is no physical connection between the two). For example, during installation, the substrate 120 and the electrical connection part 80 are separately mounted on the chip holder 70. The substrate 120 and the electrical connection part 80 can be arranged vertically, parallelly or obliquely, as long as they are insulated from each other and matched with the stylus holder 91 on the printer; then, the combination of the chip holder 70, the chip 20 and the electrical connection part 80 is mounted on the box body 50 to form a whole of the ink cartridge 10.

[0110] Another feasible implementation is that the chip holder 70 is conductive, and the electrical connection part 80 and the chip 20 are installed on the chip holder 70. Since the chip holder 70 is conductive, the fifth terminal 205a can be electrically connected to the chip 20 through the chip holder 70. Of course, the terminal arrangement on the chip 20 and the terminal arrangement on the electrical connection part 80 need to satisfy the adaptable connection with the contact pin holder 91 on the printer.

[0111] Embodiment 7 Reference Fig.29 As shown, the receiving portion 411 can be integrally formed on the front face 107 of the box body 50, and an intermediate medium such as a chip holder can also be used as the receiving portion 411. In this embodiment, a chip holder is used as the receiving portion 411. Fig.33 As shown, a conductive member 108 (equivalent to the conductive device of the eighth embodiment) is disposed on the receiving portion 411 , and an electrical connection portion 109 (equivalent to the second component / conductive member 500 of the first embodiment) and a chip 20 are mounted on the receiving portion 411 .

[0112] like Figure 30-Figure 32 As shown, the chip 20 includes a substrate 120, which is a planar extended plate-shaped structure. The substrate 120 has a largest outer surface as a first external connection surface 102a (equivalent to the front surface 301a of the first embodiment), and the surface opposite to the first external connection surface 102a is a first back connection surface 103a (see Fig.31 ) (equivalent to the rear surface 301b of the first embodiment), a plurality of terminals are arranged on the first external connection surface 102a, a wafer 104a and a first contact 207 (equivalent to the internal terminal 330 of the first embodiment) connected to the wafer 104a are arranged on the first back connection surface 103a. The electrical connection portion 109 includes a conductive plate 113a (equivalent to the second component / conductive member 500 of the first embodiment), the conductive plate 113a is a plate-like structure extending in a plane, the conductive plate 113a uses the surface with the largest area as the second external connection surface 111b, and the surface opposite to the second external connection surface 111b is the second back connection surface 112b, an external terminal (the first terminal 201a in this embodiment) is arranged on the second external connection surface 111, and a second contact 206a is arranged on the second back connection surface 112b opposite to the external terminal, and the first contact 207 and the second contact 206a are electrically connected to the wafer 104a through the conductive member 108.

[0113] A plurality of terminals are provided on the first external surface 102a of the substrate 120, and an external terminal (equivalent to the extension portion 530 of the first embodiment) is provided on the second external surface 111b of the electrical connection portion 109. The external terminal provided on the electrical connection portion 109 can be selected as any one of the first terminal 201a, the second terminal 202a, the third terminal 203a or the fourth terminal 204a. The first external surface 102a is provided with other terminals and a fifth terminal 205a except for the terminal on the second external surface 111b. This embodiment only shows one of the situations: the external terminal on the electrical connection portion 109 can be the first terminal 201a, and the first external surface 102a of the substrate 120 is provided with a second terminal 202a to a fifth terminal 205a.

[0114] The conductive plate 113a of the present embodiment is a rectangular parallelepiped structure. Of course, the electrical connection portion 109 can also be of any shape, such as a prism, a cylinder, etc., as long as the terminal can be set on the second external surface 111b of the conductive plate 113a and can be adapted to connect with the contact pin 901. The shape of the electrical connection portion 109 is not limited here.

[0115] like Fig.33 As shown, during installation, the substrate and the electrical connection portion 109 of the chip 20 need to be installed on the receiving portion 411, so that the second contact 206a on the electrical connection portion 109 and the first contact 207 on the substrate 120, the wafer 104a and the conductive member 108 are closely fitted. The chip 20 can be fixed on the receiving portion 411 by matching the concave portion with the convex portion, or by bonding, etc. The installation is completed as shown in FIG. Fig.34 .

[0116] It is understandable that there may be a distance between the substrate 120 and the electrical connection part 109 in space, that is, there may be a gap or height difference between the two. The height difference means that the ends in the direction from the rear to the front 107 are not flush, and the deformation amplitudes of the corresponding contact pins in the installed state are inconsistent, and it is only necessary to meet the connection with the contact pin 901. For example, during installation, the substrate 120 and the electrical connection part 109 are separately installed on the receiving part 411. Among them, the substrate 120 and the electrical connection part 109 can be arranged vertically, parallel or intersectingly, as long as the terminals on the two are matched with the contact pins 901 on the printer.

[0117] In this embodiment, the first terminal 201a is separately arranged on the second external surface 111b of the electrical connection part 109, and the second contact 206a on the electrical connection part 109 is connected to the first contact 207 of the substrate 120 and the wafer 104a through the conductive member 108, thereby reducing the possibility of short circuit with other terminals and increasing the safety of the chip 20 and the printer.

[0118] Embodiment 8 See also Fig.35 The ink cartridge 10 corresponding to this embodiment is basically the same as that of the seventh embodiment, and the corresponding structures use the same reference numerals. The only difference is that in this embodiment, the receiving portion 411 is configured to be an integral structure with the cartridge body 50.

[0119] like Fig.35 As shown, the receiving portion 411 is provided with a conductive member 108, and then the chip 20 is mounted on the receiving portion 411. When the chip 20 is mounted on the receiving portion 411, the second contact 206a on the electrical connection portion 109 is tightly fitted with the first contact 207 of the substrate 120, the wafer 104a and the conductive member 108. It can be understood that the electrical connection portion 109 can be of any shape, and the chip 20 and the electrical connection portion 109 are separately fixed on the receiving portion 411 and are both in contact with the conductive member 108.

[0120] A plurality of terminals are provided on the first external surface 102a of the substrate 120, and the plurality of terminals include a second terminal 202a, a third terminal 203a, and a fourth terminal 204a. A first terminal 201a is provided on the electrical connection portion 109. After installation is completed, the arrangement of the terminals as a whole when observed from the X-axis direction is as follows: the first terminal 201a and the fourth terminal 204a are arranged in the first row, the second terminal 202a and the third terminal 203a and the fifth terminal 205a are arranged in the second row, and the projections of the first terminal 201a, the second terminal 202a, the third terminal 203a, and the fourth terminal 204a in the installation direction do not overlap, and the contact portions of the first terminal 201a, the second terminal 202a, the third terminal 203a, the fourth terminal 204a, and the fifth terminal 205a can be adapted and connected with the plurality of contact pins 901 on the contact pin holder 91.

[0121] Of course, the external terminal on the second external surface 111b of the electrical connection portion 109 can be selected as any one of the first terminal 201a, the second terminal 202a, the third terminal 203a or the fourth terminal 204a, and this embodiment only shows one possible case.

[0122] The above embodiment can reduce the possibility of short circuit with other terminals by setting an external terminal on the second external connection surface 111 b, thereby increasing the safety of the chip 20 and the printer.

[0123] Embodiment 9 In this embodiment, the first terminal 131, the second terminal 132, the third terminal 133, the fourth terminal 134 and the fifth terminal 135 (equivalent to the fifth terminal of the third embodiment) are all arranged on the front surface 120a of the substrate 120. In this embodiment, the first terminal 131, the second terminal 132, the third terminal 133, the fourth terminal 134 and the fifth terminal 135 have different coordinates on the Y axis, the first terminal 131 and the fourth terminal 134 have the same coordinates on the Z axis, the second terminal 132, the third terminal 133 and the fifth terminal 135 have the same coordinates on the Z axis, but the first terminal 131 and the second terminal 132 have different coordinates on the Z axis. Among them, the fifth terminal 135 is located on the front surface 120a close to the right side 120d, away from the other four terminals.

[0124] The ink cartridge 10 is provided with a chip mounting portion (equivalent to the receiving portion 411 of the first embodiment) for mounting the chip 100. The chip mounting portion includes a first positioning column 121a, a second positioning column 122a, and a protruding rib 310c. The first positioning column 121a and the second positioning column 122a (equivalent to the positioning portion 312 of the first embodiment) are combined with the first hole 121 and the second hole 122 (equivalent to the positioning column 414 of the first embodiment) of the chip in a protruding manner, and then the chip 100 is fixed to the box body by means of hot welding.

[0125] The direction in which the ink cartridge 10 is installed on the carriage of the ink cartridge installation part 90 is defined as the installation direction P. The installation direction P is also the direction in which the substrate 100 is installed on the carriage of the ink cartridge installation part 90. In the present embodiment, the installation direction MD is the +Z direction. Two directions orthogonal to each other are defined as the first direction and the second direction. In the present embodiment, the first direction is the Z direction, and the second direction is the X direction. The chip ink cartridge installation part is observed from above. Two orthogonal straight lines are defined as the first imaginary line C1 and the second imaginary line C2. The first imaginary line C1 is the direction along the first direction, and the second imaginary line C2 is the direction along the second direction. When the ink cartridge 10 equipped with the chip 100 of the present embodiment is installed in the box body, the protruding rib 310c will cause the chip to be lifted along the +X axis direction near the fifth terminal 135. In the plan view, when all the contact portions of all the terminals set on the substrate are projected onto the second imaginary line C2, the contact portions of the terminals are not all projected onto the second imaginary line C2. The beneficial effects of such a design are as follows: the substrate and the front end surface of the consumable box are placed at an inclined angle a, the fifth terminal 135 is higher than other terminals in the direction perpendicular to the front end surface, the fifth contact pin 915 contacts the fifth terminal 135 in advance and increases the contact pressure, thereby ensuring stable contact of the fifth terminal 135, preventing excessive current from damaging the chip equipment, and improving the safety of chip use.

[0126] When the ink cartridge 10 equipped with the chip 100 of the present embodiment is installed in the ink cartridge installation portion 90, the fifth terminal 135 of the chip 100 first contacts the contact pin head of the fifth vertical portion 915k of the fifth contact pin 915, thereby realizing electrical connection between the fifth terminal 135 and the fifth contact pin 915. The remaining terminals also abut against the contact pin heads of the remaining contact pins to realize electrical connection.

[0127] The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
