Technical Field

[0003] This invention relates to the field of printing consumables technology, and more particularly to a printing consumable and a chip. Background Technology

[0004] Printing consumables are components that need to be replaced frequently. A chip is a component of printing consumables. Taking ink cartridges as an example: the chip on an ink cartridge stores information such as the manufacturer, ink level, cartridge type, and ink color. The chip in an inkjet printer plays a crucial role in the normal operation of the printer.

[0005] Miniaturization of chips is more conducive to the miniaturization of printing consumables or printers, which helps to save space and avoid waste. In existing technologies, due to the trend of ink cartridge miniaturization, the chip can be placed in a smaller position and the chip area is smaller. Therefore, the area of ​​the chip terminal is also smaller. During use, considering the possibility of ink cartridge installation errors, the chip terminal may not be able to make stable contact with the printer's internal pins, affecting the normal printing of ink cartridges and reducing the user experience. Summary of the Invention

[0006] This invention provides a printing consumable and a chip to at least solve the problem of unstable electrical contact caused by chip miniaturization and the development of chip miniaturization.

[0007] The graphic generation apparatus involved in this invention can be a printer.

[0008] To achieve the above objectives, the present invention provides a printing consumable for installation into a mounting part of a graphic generation device. The mounting part is provided with a base, and the base is provided with a plurality of styluses. The printing consumable includes a housing and an electrical connection assembly.

[0117] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0118] Printing consumables are frequently replaced components of graphics generating devices. A chip for printing consumables is one such component. Printing consumables can include ink cartridges, toner cartridges, ribbons, etc. (Reference) Figure 1 As shown, the printing consumable is an ink cartridge. Chip 30 is used to store information such as manufacturer information, ink volume information, ink cartridge type information, and ink color. Chip 30 plays a decisive role in the normal operation of the graphics generation device.

[0119] Chips typically have terminals with small area sizes. During installation, it is difficult to ensure good contact between the pins and the terminals. This usually requires increasing the size of the terminals, which is not conducive to the miniaturization of chips.

[0120] The present invention provides a printing consumable and a chip that enables the terminals on the chip to be arranged compactly, which is conducive to the miniaturization of the chip and saves the space occupied by the chip; at the same time, it is also conducive to the stable contact between the chip terminals and the contact pins, and improves the stability of electrical connection.

[0121] The following description, with reference to the accompanying drawings, uses an ink cartridge as an example to illustrate the printing consumables provided in the embodiments of the present invention. The printing consumables can be ink cartridges that store ink, toner cartridges that store toner, ribbons, etc. The present invention will be described using ink cartridges as an example of printing consumables.

[0122] refer to Figure 1 and Figure 2 As shown, the present invention provides a printing consumable for installation into a mounting part 90 of a graphics generating device. The mounting part 90 is provided with a base 910, and the base 910 is provided with a plurality of contact pins 91. The mounting part 90 is a component of the graphics generating device and is used to support a plurality of printing consumables (which may also be ink cartridges). (See reference...) Figure 2 As shown, the ink cartridge is detachably installed into the mounting section 90 in the direction indicated by arrow P. After the ink is used up, it is convenient to replace the ink cartridge by removing the ink cartridge and reinstalling a new one.

[0123] The graphic generation device in this embodiment includes, but is not limited to, printers, copiers, etc.

[0124] In one possible implementation method, refer to Figure 3 and Figure 5 As shown, the multiple contact pins 91 are designated as first contact pin 911, second contact pin 912, third contact pin 913, fourth contact pin 914, and fifth contact pin 915. The first contact pins 911 through 915 have identical structures. Each contact pin 91 is a thin, sheet-like metal plate, which provides conductivity and is resistant to wear. The base 910 has multiple slits 981-989. Slits 981, 982, 983, 984, and 985 correspond to the first contact pin 911, second contact pin 912, third contact pin 913, fourth contact pin 914, and fifth contact pin 915, respectively. The slits are U-shaped and have an opening in the +Z axis direction. The first contact pin 911 is installed into one of the slits 981 through the slit opening. The installation methods for the second contact pins 912, 913, 914, and 915 are the same and will not be repeated here.

[0125] refer to Figure 3 , Figure 4 and Figure 5 As shown, one side of each of the first to fifth contact pins 915 is connected to the main circuit of the graphics generating device via the internal circuitry of the mounting portion 90; the other side is connected to the chip 30. Taking the first contact pin 911 as an example, the first contact pin 911 includes a first connecting portion 911a, a second connecting portion 911b, and a third connecting portion 911c, wherein the third connecting portion 911c is connected to the first connecting portion 911a and the second connecting portion 911b. The first connecting portion 911a is used to contact the terminal 31 of the chip 30; the second connecting portion 911b is used to connect to the internal circuitry of the graphics generating device, for example, it is connected to the main circuitry of the graphics generating device via the mounting portion chip. The first contact pin 911 is fixed in a slit via the third connecting portion 911c or a portion thereof, such as the horizontal portion 911h of the third connecting portion 911c. The first connecting part 911a and the second connecting part 911b are disposed at the end of the first contact pin 911, so that the first connecting part 911a and the second connecting part 911b can be elastically deformed and easily return to their original shape after deformation.

[0126] The first connecting portion 911a and the second connecting portion 911b of the first stylus 911 are respectively disposed on both sides of the base 910. The first connecting portion 911a and the second connecting portion 911b protrude from the base 910, while the third connecting portion 911c does not protrude from the base 910. In one possible implementation, the first connecting portion 911a and the second connecting portion 911b protrude from the base 910, and the base 910 is located between the first connecting portion 911a and the second connecting portion 911b.

[0127] The third connecting portion 911c includes a first vertical portion 911k and a second vertical portion 911j parallel to direction P, and a horizontal portion 911h perpendicular to direction P, wherein the horizontal portion 911h connects the first vertical portion 911k and the second vertical portion 911j. The first vertical portion 911k and the second vertical portion 911j extend along direction P. The end of the first vertical portion 911k connects to the first connecting portion 911a, and the end of the second vertical portion 911j connects to the second connecting portion 911b. When the horizontal portion 911h or the first vertical portion 911k and the second vertical portion 911j are fixed in the slit along the +Z axis direction, this structure of the first stylus 911 allows the first connecting portion 911a and the second connecting portion 911b of the first stylus 911 to be elastic, avoiding wear of the first stylus 911 due to hard contact with the internal circuitry and chip of the graphics generation device. 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 descriptions will not be provided here.

[0128] The two directions orthogonal to the first direction are the second direction and the third direction, respectively, and the second direction is parallel to the front surface 120a of the substrate 120. It is easy to understand that both the second direction and the third direction are perpendicular to the first direction.

[0129] A three-dimensional Cartesian coordinate system is established, namely the XYZ axis coordinate system, where the X, Y, and Z axes are perpendicular to each other. The three-dimensional Cartesian coordinate system of the ink cartridge is consistent with the three-dimensional Cartesian coordinate system of the mounting part 90. The first direction is the direction indicated by the Z axis, the second direction is the direction indicated by the Y axis, and the third direction is the direction indicated by the X axis.

[0130] Before the printing consumables are installed into the mounting section 90, at least one stylus 91 is spaced apart from the other stylus in a second direction (Y-axis direction) that intersects with the first direction (i.e., the mounting direction P, the Z-axis direction).

[0131] refer to Figure 5 and Figure 6As shown, the printing consumables provided in this embodiment include: a cartridge 10 and an electrical connection assembly. The electrical connection assembly is interconnected with the cartridge 10. The electrical connection assembly includes a chip 30. The chip 30 includes a substrate 120 and a plurality of terminals 31 disposed on the substrate 120. The terminals 31 are all used for electrical connection with the stylus 91. The plurality of terminals 31 include direct contact terminals and at least one auxiliary contact terminal. At least one of the cartridge 10 and the electrical connection assembly is provided with a guide assembly. The guide assembly is configured to abut against at least one stylus 91 in at least one direction, so that the stylus 91 is deformed and makes corresponding contact with the auxiliary contact terminal.

[0132] Each terminal 31 has a contact portion for electrical contact with the stylus 91. Multiple contact portions are arranged in at least two rows at intervals along a first direction (mounting direction P) on which the printing consumable is mounted to the mounting portion 90. The contact portion of at least one auxiliary contact terminal and the contact portion of at least one other terminal 31 are projected onto a third direction portion of a first plane, wherein the first plane is a plane perpendicular to the first direction.

[0133] If the contact portion of terminal 31 is not directly or entirely located on the front surface 120a of substrate 120, the contact portion is projected onto the first plane. For example, if the contact portion of auxiliary contact terminal is not located on the front surface 120a of substrate 120, the contact portion of auxiliary contact terminal is projected onto the first plane to form an auxiliary contact portion projection area. This auxiliary contact portion projection area coincides with the projection of the contact portion of at least one other terminal 31 onto the first plane along a third direction, thereby facilitating the miniaturization of the chip.

[0134] The printing consumable provided by this invention, due to the guiding component that guides the deformation of the stylus 91, enables the stylus 91 to achieve good electrical contact with the compactly arranged terminals, overcoming the limitation of the chip 30's small size, thus facilitating chip miniaturization and saving space. The guiding component abuts against the stylus, which can limit the position of the chip 30 through the stylus 91, ensuring the stability of the chip 30's contact position and reducing the occurrence of unstable contact between the terminals on the chip 30 and the stylus 91 inside the printer, solving the problem of unstable electrical contact. Furthermore, the projection of the contact portion of at least one auxiliary contact terminal on the front surface 120a coincides with the contact portion of at least one other terminal 31, further contributing to chip miniaturization.

[0135] The guiding component has a force-applying part configured to abut against at least one of the plurality of contact pins 91 in a second direction (width direction, Y-axis direction) intersecting the first direction (mounting direction P), causing the contact pin 91 to deform and contact the contact portion of the auxiliary contact terminal. A direct contact terminal is disposed on the front surface 120a of the chip 30 away from the housing 10, and the first and second directions are parallel to the front surface 120a. During the installation of the printing consumable into the mounting portion 90, the contact pin 91 corresponding to the auxiliary contact terminal first contacts the guiding component, causing the contact pin 91 to deform as it gradually approaches the auxiliary contact terminal. Specifically, the contact pin 91 deflects towards the auxiliary contact terminal under the guidance of the force-applying part and gradually approaches the auxiliary contact terminal until it makes contact.

[0136] refer to Figure 1 and Figure 2 As shown, when the printing consumable is an ink cartridge, the printing consumable also includes a handle 12, which facilitates securing the ink cartridge to the mounting part 90 and prevents the ink cartridge from detaching from the mounting part 90. The bottom of the cartridge body 10 has an ink outlet 13, and the mounting part 90 has an ink supply part 92 and an opening 95. The ink cartridge is installed into the mounting part 90 through the opening 95 along the installation direction P. The cartridge body 10 stores ink, and the ink reaches the ink supply part 92 through the ink outlet 13, thereby supplying the ink to the print head, so that the ink can be used to perform the printing action.

[0137] Taking the direction in which the ink cartridge is installed into the mounting part 90 as the -Z-axis direction (i.e., the installation direction P), the direction in which the ink cartridge detaches from the mounting part 90 is the +Z-axis direction. The opening 95 is located in the +Z-axis direction, and the bottom wall of the ink cartridge is located in the -Z-axis direction. Generally, the graphics generating device is placed flat on an office desk or printing table, with the opening 95 of the mounting part 90 positioned above the direction of gravity and the bottom wall of the ink cartridge facing downwards, facilitating user installation and removal of the ink cartridge. In one possible implementation, the mounting part 90 may have multiple or one mounting compartment for holding the ink cartridges. Four ink cartridges may be installed into the mounting part 90, and each cartridge can store four different colors of ink, such as black, yellow, blue, and red.

[0138] The stylus 91 is located on the inner wall of the mounting chamber, with four mounting positions arranged sequentially along the Y-axis. The direction from inside the mounting chamber towards the stylus 91 is the +X-axis direction.

[0139] refer to Figure 2 and Figure 6As shown, the chip 30 includes a substrate 120 and a memory. The memory and terminals 31 are disposed on the substrate 120. The memory is used to store information such as manufacturer information, ink volume information, ink cartridge type information, and ink color. When the ink cartridge is installed in the mounting part 90 of the graphics generating device, data transmission, confirmation, and data interaction between the memory and the graphics generating device are realized through the connection between the terminals 31 and the contact pins 91 of the graphics generating device.

[0140] refer to Figure 5 and Figure 6 As shown, the substrate 120 has a front surface 120a, a rear surface (not shown), a left side surface 120c, a right side surface 120d, a top surface 120e, and a bottom surface 120f. The front surface 120a is located on the +X side of the rear surface; the left side surface 120c is located on the -Y axis side of the right side surface 120d; and the top surface 120e is located on the +Z axis side of the bottom surface 120f. Terminal 31 is located on the front surface 120a. The memory can be disposed on any one or any of the surfaces of the substrate 120.

[0141] In one possible implementation, the memory is disposed on the rear surface of the substrate 120.

[0142] The specific shape and structure of chip 30 are not limited here and can be set according to specific needs. For example, chip 30 can be set as a rectangular structure, a chamfered rectangle structure, a rounded rectangle structure, a T-shaped structure, a trapezoidal structure, a parallelogram structure, etc. In addition, there are no limitations on the location of the memory. For example, the memory can be set on the rear side of chip 30 near direction P, or on the front side of chip 30 near direction P, or in the middle of chip 30. The specific settings can be made according to specific needs, which will not be elaborated here.

[0143] In one possible implementation method, refer to Figure 8 and Figure 9 As shown, the multiple terminals 31 are respectively the first terminal 131, the second terminal 132, the third terminal 133, the fourth terminal 134, and the fifth terminal 135, wherein:

[0144] The first terminal 131, i.e. the data terminal, is used to transmit or receive data signals, and is also used to detect a short circuit between the first terminal 131 and at least one of the second terminal 132, the third terminal 133 or the fourth terminal 134.

[0145] The second terminal 132, the clock terminal, is used to receive clock signals;

[0146] The third terminal 133, also known as the power supply terminal, is used to receive a power supply potential different from the ground potential, such as 3.6V or 3.3V. Power is supplied to the memory for operation through the third terminal 133.

[0147] The fourth terminal 134, also known as the reset terminal, is used to reset the data inside the chip.

[0148] The fifth terminal, 135, is the grounding terminal, used to receive grounding potential and transmit grounding signals.

[0149] Each terminal 31 has a contact portion C for electrical contact with the stylus 91, and the multiple terminals 31 are arranged in two rows at intervals along a first direction. The contact portion C is the contact area on the terminal 31 that is most likely to contact the stylus 91 when the ink cartridge is installed on the graphics generating device.

[0150] In one possible implementation, when the chip is mounted to the mounting portion, the auxiliary contact pin deforms and makes corresponding contact with the auxiliary contact terminal; the distance between the contact portion of at least one direct contact terminal and the contact portion of the auxiliary contact terminal in the mounted state is less than the distance between the corresponding direct contact pin and the auxiliary contact pin in the unmounted state. This makes the arrangement of the terminals 31 more compact, which is beneficial for the miniaturization of the chip 30.

[0151] In one possible implementation, multiple terminals 31 are arranged in two rows spaced apart from each other along a first direction;

[0152] In one possible implementation, each terminal 31 has a contact portion for electrical contact with the contact pin 91. The multiple terminals 31 are arranged in at least two rows spaced apart along a first direction. On the front surface 120a, the contact portion of at least one auxiliary contact terminal coincides with the projected portion of the contact portion of at least one of the remaining terminals on a first plane (XY plane). This makes the arrangement of the terminals 31 more compact, which is beneficial for miniaturization of the chip 30. The first direction can be the direction indicated by the -Z axis, i.e., the mounting direction P.

[0153] The contact portion of at least one auxiliary contact terminal coincides with the projection portion of the contact portion of at least one of the remaining terminals onto the first plane (XY plane); the remaining terminals refer to terminals other than at least one auxiliary contact terminal, and the remaining terminals may be direct contact terminals or auxiliary contact terminals.

[0154] Furthermore, on the front surface 120a, the contact portion of at least one auxiliary contact terminal coincides with the projection portion of the contact portion of at least one direct contact terminal on the first plane (XY plane).

[0155] Furthermore, there are two auxiliary contact terminals, and the projection portions of the contact portions of the two auxiliary contact terminals on the first plane (XY plane) overlap on the front surface 120a.

[0156] refer to Figure 6 and Figure 8 As shown, the chip 30 has at least one positioning hole. In one possible implementation, the chip 30 has two positioning holes, namely a first hole 121 and a second hole 122. The first hole 121 and the second hole 122 are both through holes on the substrate 120, both penetrating the front surface 120a and the rear surface of the substrate 120, and are used for positioning.

[0157] In one possible implementation method, refer to Figure 8 As shown, the first hole 121 is a notch or through hole on the +Z axis side of the substrate 120.

[0158] In one possible implementation method, refer to Figure 9 and Figure 10 As shown, the electrical connection assembly also includes a chip socket 20, which is disposed on the housing 10. The chip 30 is disposed on the side of the chip socket 20 facing away from the housing 10. At least one of the housing 10, the chip socket 20, and the chip 30 is provided with a guide component. The chip socket 20 is provided with at least one positioning post, and the specific shape and number of the positioning post are not limited here.

[0159] In one possible implementation, the chip holder 20 is provided with two positioning posts, namely a first positioning post 201 and a second positioning post 202. When the chip 30 is installed in the chip holder 20, the first hole 121 and the second hole 122 cooperate with the first positioning post 201 and the second positioning post 202 respectively, to position the chip 30 and prevent the chip 30 from shifting its position during installation or during use after installation.

[0160] It should be noted that the number of positioning holes is not limited. Specifically, only one positioning hole can be provided, such as the first hole 121, or two or more positioning holes can be provided. Furthermore, the shape of the positioning holes is also not limited; they can be circular, square, or irregularly shaped. Similarly, the specific shape and number of positioning posts are not subject to excessive restrictions. The location of the positioning holes on the chip 30 is also not limited, as long as they can mate with the positioning holes and fulfill their corresponding functions. For example, they can be located at the edge of the substrate 120, or they can be located through the substrate 120 near its edge.

[0161] refer to Figure 7 As shown, the chip socket 20 includes a receiving portion 22 that mates with the chip 30, referenced. Figure 5 and Figure 6As shown, the side of the substrate 120 facing away from the chip holder 20 is the external surface 321a (also referred to as the front surface 120a), which is parallel to the YZ plane. Ink cartridges can be broadly classified into two types based on their mounting method. The first type of ink cartridge has its mounting direction parallel to the external surface 321a (also referred to as the front surface 120a). The second type of ink cartridge has its mounting direction not completely parallel to the external surface 321a (front surface 120a), meaning the printing consumable is installed at an angle relative to the front surface 120a in the mounting section 90. Specifically, the second type of ink cartridge has its mounting direction basically parallel to the external surface 321a.

[0162] Terminal 31 is used for electrical connection with corresponding contact pin 91, and terminal 31 is disposed on outer surface 321a. At least one of the plurality of terminals 31 is an auxiliary contact terminal, and the terminals other than the auxiliary contact terminal are direct contact terminals.

[0163] Among the multiple contact pins 91, at least one contact pin 91 is an auxiliary contact pin, and the contact pins 91 other than the auxiliary contact pin are direct contact pins. In the installed state, the auxiliary contact pin deforms and makes contact with the corresponding auxiliary contact terminal.

[0164] During the installation of printing consumables, the direct contact terminal can directly contact the corresponding contact pin 91. The auxiliary contact terminal needs to be guided by the guide component so that the corresponding contact pin 91 can deform before it can contact the auxiliary contact terminal, thereby ensuring a stable electrical connection between the auxiliary contact terminal and the contact pin 91.

[0165] On the front surface, at least one contact portion of the auxiliary contact terminal coincides with the projection portion of the contact portion of at least one of the remaining terminals 31 onto a first plane. The first plane may be an XY plane, i.e., the front surface 120a of the substrate 120.

[0166] The plurality of terminals 31, at least one of which is an auxiliary contact terminal, and at least one of the housing 10, chip holder 20 and chip 30 is provided with a guide component, which is configured to guide at least one pin 91 to deform in at least one direction so that the deformed pin 91 makes corresponding contact with the auxiliary contact terminal.

[0167] Example 1

[0168] In this embodiment, reference Figure 5 , Figure 6 and Figure 7 As shown, the guiding component includes a first guiding structure 61, which includes a first limiting part 611 connected to the chip socket 20. A first mounting hole is provided in the chip 30, and the first limiting part 611 extends through the first mounting hole to the side of the chip 30 facing away from the chip socket 20 (specifically the front surface 120a). A force-applying part is provided on the first limiting part 611.

[0169] The first limiting part 611 has a first force-applying surface 6111 facing the auxiliary contact terminal. The force-applying part includes the first force-applying surface 6111. From one end of the first limiting part 611 connected to the chip holder 20 to one end of the first limiting part 611 protruding from the chip 30, the first force-applying surface 6111 gradually tilts toward the auxiliary contact terminal.

[0170] In this embodiment, the first mounting hole is the fourth hole 124. The right side wall of the fourth hole 124 abuts against the first force-applying surface 6111 of the first limiting part 611 to prevent the chip 30 from shifting in the -Y axis direction and to strengthen the limiting of the chip 30.

[0171] During the process of inserting the ink cartridge containing the chip 30 and chip holder 20 provided in this embodiment into the mounting part 90 of the graphic generation device, the first limiting part 611 contacts the -Y axis side surface of the first connecting part 912a of the second contact pin 912 and presses the second contact pin 912 in the +Y axis direction, causing the first connecting part 912a of the second contact pin 912 to deflect in the +Y axis direction. In this embodiment, there is one auxiliary contact terminal. The second terminal 132 is an auxiliary contact terminal, and the first terminal 131, the third terminal 133, the fourth terminal 134, and the fifth terminal 135 are direct contact terminals. Correspondingly, the second contact pin 912 is an auxiliary contact pin, and the first contact pin 911, the third contact pin 913, the fourth contact pin 914, and the fifth contact pin 915 are direct contact pins. In the installed state, the distance in the Y-axis direction between the contact portion C of the second terminal 132 (auxiliary contact terminal) and the contact portion C of the first terminal 131 (direct contact terminal) is less than the distance in the Y-axis direction between the first contact pin 911 (corresponding direct contact pin) and the second contact pin 912 (auxiliary contact pin) in the natural state. This results in a compact terminal arrangement, which is beneficial for miniaturizing the chip 30. That is, the distance between the contact portion of the first terminal 131 (direct contact terminal) and the contact portion of the second terminal 132 (auxiliary contact terminal) in the installed state is less than the distance between the corresponding direct contact pin (first contact pin 911) and the auxiliary contact pin (second contact pin 912) in the non-installed state / natural state. Furthermore, the distance between the contact portion of the third terminal 133 / fourth terminal 134 / fifth terminal 135 (direct contact terminal) and the contact portion of the second terminal 132 (auxiliary contact terminal) in the installed state is less than the distance between the corresponding direct contact pin (third contact pin 913 / fourth contact pin 914 / fifth contact pin 915) and the auxiliary contact pin (second contact pin 912) in the non-installed state / natural state.

[0172] Similarly, the first limiting part 611 protrudes from the substrate 120 in the X-axis direction, so that when the ink cartridge or chip holder 20 is accidentally dropped on the floor and the front surface 120a of the substrate 120 is facing the ground, the first limiting part 611 will contact the ground before the chip substrate 120, thus preventing the chip 30 from being damaged or scratched due to the impact.

[0173] It should be noted that the first limiting part 611 can also be set on the +Y axis or -Y axis side of any other terminal, as long as it can achieve the beneficial effect of chip miniaturization.

[0174] refer to Figure 1 and Figure 2 As shown, when the printing consumable is installed in the graphic generation device, the stylus 91 in contact with the chip 30 undergoes elastic deformation, and a static friction force is generated between the chip 30 and the stylus 91 to suppress cartridge movement. However, because the deformation amplitude of the stylus 91 is basically uniform and the static friction force it provides is small, it is insufficient to suppress cartridge displacement. The printing consumable provided by this invention can achieve a larger deformation amplitude in the width direction when installed, thereby providing a better suppression effect on cartridge displacement in the width direction.

[0175] Example 2

[0176] refer to Figure 8 , Figure 9 and Figure 10 As shown, in this embodiment, there is an accommodating space between the first limiting part 611 and the inner wall of the first mounting hole, and at least a portion of the auxiliary contact terminal is located on the inner wall of the first mounting hole; the accommodating space is configured to accommodate one of the plurality of contact pins 91 so that the contact pin 91 makes corresponding contact with the auxiliary contact terminal.

[0177] In this embodiment, the first mounting hole can be the fourth hole 124. There is an accommodating space between the first limiting part 611 and the inner wall of the fourth hole 124. When the chip 30 and the contact pin 91 are electrically connected, the second contact pin 912 is in the accommodating space. The first limiting part 611 presses the first connecting part 912a of the second contact pin 912 toward the third contact pin 913. The distance between the contact part C of the second terminal 132 and the contact part C of the third contact pin 913 along the Y-axis is less than the distance between the first contact pin 911 and the third contact pin 913 in the Y-axis direction under natural conditions.

[0178] In one possible implementation, the contact portion C of the second terminal 132 may be disposed on the front surface 120a of the substrate 120 or on the inner sidewall of the fourth hole 124.

[0179] The rest of the content is the same as in Example 1.

[0180] Example 3

[0181] refer to Figure 11 , Figure 12 and Figure 13 As shown, the difference between this embodiment and Embodiment 1 and Embodiment 2 is that there are two first guiding structures 61.

[0182] The first guiding structure 61 also includes a second limiting part 612, which is connected to the chip holder 20. A second mounting hole is also provided in the chip 30. The second limiting part 612 extends through the second mounting hole to the side of the chip 30 facing away from the chip holder 20. The second limiting part 612 is configured to abut against the two contact pins 91 respectively with the first limiting part 611, so that the two contact pins 91 are deformed in opposite and close directions and abut against the two auxiliary contact terminals respectively. On the front surface 120a, the projection portions of the contact portions of the two auxiliary contact terminals on the first plane (i.e., the XY plane) coincide.

[0183] The second force-applying surface 6121 of the second limiting part 612 facing the auxiliary contact terminal, the force-applying part includes the second force-applying surface 6121; the second force-applying surface 6121 is an inclined surface, from one end of the second limiting part 612 connected to the chip holder 20 to one end of the second limiting part 612 protruding from the chip 30, the second force-applying surface 6121 gradually tilts towards the auxiliary contact terminal.

[0184] In one possible implementation, a first limiting portion 611 is disposed on the +Y axis side of the first terminal 131 and the -Y axis side of the fourth terminal 134. The -Z axis side surface of the first limiting portion 611 is a first guide surface 6112, and the -Y axis side surface is a first force-applying surface 6111. The first guide surface 6112 extends from the bottom surface 120f toward the top surface 120e and slopes toward the left side surface 120c.

[0185] The second limiting part 612 is disposed on the -Y axis side of the second terminal 132. The -Z axis side surface of the second limiting part 612 is the second guide surface 6122, and the +Y axis side surface is the second force application surface 6121. The second guide surface 6122 extends from the bottom surface 120f toward the top surface 120e and is inclined toward the right side surface 120d.

[0186] In this embodiment, the first mounting hole and the second mounting hole are the third hole 123 and the fourth hole 124, respectively. After the chip 30 and the chip holder 20 are installed, the first limiting part 611 and the second limiting part 612 limit the chip 30 in the Y-axis direction.

[0187] In one possible implementation, the first force-applying surface 6111 of the first limiting part 611 abuts against a side wall of the third hole 123 to prevent the chip 30 from shifting in the +Y axis direction, and the second force-applying surface 6121 of the second limiting part 612 abuts against a side wall of the fourth hole 124 to prevent the chip 30 from shifting in the -Y axis direction.

[0188] In addition to limiting the chip 30 in the Y-axis direction, the first limiting part 611 and the second limiting part 612 can also be configured to limit the chip 30 in the Z-axis direction to prevent the chip 30 from shifting its position in the Z-axis direction.

[0189] It should be noted that, in addition to the cooperation between the chip socket 20 and the chip 30, the chip 30 also needs to be fixed to the chip socket 20 by means of hot soldering to enhance the stability of the connection between the chip socket 20 and the chip 30.

[0190] Furthermore, in this embodiment, both the first limiting part 611 and the second limiting part 612 are protrusions that extend beyond the chip 30 in the X-axis direction. The advantage of this design is that when the ink cartridge or chip holder 20 is accidentally dropped onto the floor with the front surface 120a of the chip 30 facing the ground, the first limiting part 611 and the second limiting part 612 will contact the ground before the chip 30, thus preventing the chip 30 from being damaged or scratched due to the impact.

[0191] Furthermore, when the ink cartridge is in the installed state, the force applied by the first stylus 911 to the first guide surface 6112 of the first limiting part 611 has a component force in the -Y axis direction, and the force applied by the second stylus 912 to the second guide surface 6122 of the second limiting part 612 has a component force in the +Y axis direction. The two can cancel each other out, so that the chip 30 is subjected to force balance in the Y axis direction, thereby improving the stability of the chip 30 installation and reducing the possibility of the chip 30 shifting its position in the Y axis direction when installed.

[0192] During the process of inserting the ink cartridge containing the chip 30 and chip holder 20 provided in this embodiment into the mounting part 90 of the graphic generation device, the second guide surface 6122 guides the second limiting part 612 into the -Y axis side of the first connecting part 912a of the second contact pin 912. The second limiting part 612 then contacts the -Y axis side surface of the first connecting part 912a of the second contact pin 912 and presses the second contact pin 912 in the +Y axis direction, causing the first connecting part 912a of the second contact pin 912 to deflect in the +Y axis direction. This results in the distance d1 in the Y axis direction between the contact part C of the second terminal 132 and the contact part C of the first terminal 131 in the installed state being less than the distance d2 in the Y axis direction between the first contact pin 911 and the second contact pin 912 in the natural state, where d2 is approximately 0.7 mm. The advantage of this design is that it allows for a compact arrangement of the terminals 31, which is beneficial for miniaturizing the chip 30.

[0193] Continuing to install the ink cartridge along the installation direction P, the first guide surface 6112 of the first limiting part 611 guides the first limiting part 611 to be located on the +Y axis side of the first connecting part 911a of the first contact pin 911. Thus, the first limiting part 611 contacts the +Y axis side surface of the first connecting part 911a of the first contact pin 911 and presses the first contact pin 911 in the -Y axis direction, causing the first connecting part 911a of the first contact pin 911 to deflect in the -Y axis direction and further shrink. In the installed state, the distance between the contact part C of the second terminal 132 and the contact part C of the first terminal 131 in the Y axis direction is less than the distance between the first contact pin 911 and the second contact pin 912 in the Y axis direction in the natural state.

[0194] In one possible implementation, the distance between the contact portion C of the second terminal 132 and the contact portion C of the first terminal 131 in the Y-axis direction in the installed state is approximately 0 to 0.5 mm.

[0195] In one possible implementation, in the installed state, at least part of the contact portion C of the second terminal 132 and the contact portion C of the first terminal 131 overlap in the Y-axis direction, that is, on the front surface 120a, the projection portions of the contact portions of the two auxiliary terminals (second terminal 132 and first terminal 131) on the first plane (XY plane) overlap.

[0196] It should be noted that the first limiting part 611 and the second limiting part 612 can also be provided on opposite sides of any other two adjacent terminals 31. For example, the first limiting part 611 is provided on the -Y axis side of the third terminal 133, and the second limiting part 612 is provided on the +Y axis side of the fourth terminal 134. During installation, the first limiting part 611 causes the first connecting part 913a of the third contact pin 913 to deflect in the +Y axis direction, and the second limiting part 612 causes the first connecting part 914a of the fourth contact pin 914 to deflect in the -Y axis direction, thereby making the distance in the Y axis direction between at least a portion of the contact part C of the third terminal 133 and at least a portion of the contact part C of the fourth terminal 134 less than the distance in the Y axis direction between the third contact pin 913 and the fourth contact pin 914 in the natural state. To illustrate further, the first limiting part 611 is disposed on the -Y axis side of the first terminal 131, and the second limiting part 612 is disposed on the +Y axis side of the third terminal 133. During installation, the first limiting part 611 causes the first connecting part 911a of the first contact pin 911 to deflect in the +Y axis direction, and the second limiting part 612 causes the first connecting part 913a of the third contact pin 913 to deflect in the -Y axis direction. This results in the distance in the Y axis direction between at least a portion of the contact portion C of the first terminal 131 and at least a portion of the contact portion C of the third terminal 133 being less than the distance in the Y axis direction between the first contact pin 911 and the third contact pin 913 in the natural state.

[0197] It should be noted that the first force-applying surface 6111 / second force-applying surface 6121 can be configured to extend along the -X direction, or to extend from the bottom surface 120f to the top surface 120e and tilt towards the right side surface 120d, or to extend from the bottom surface 120f to the top surface 120e and tilt towards the left side surface 120c, or to extend in a zigzag manner. The key is that the first force-applying surface 6111 / second force-applying surface 6121 can effectively restrict the movement of the chip 30 in the +Y axis direction or the -Y axis direction.

[0198] In one possible implementation, when the ink cartridge is in the installed state, there is a gap between the first limiting part 611 and the second limiting part 612 and the base 910.

[0199] Example 4

[0200] refer to Figure 14 , Figure 15 and Figure 16 As shown, in this embodiment, after the chip 30 and chip socket 20 are installed, the first limiting part 611 is located on the -Y axis side of the first terminal 131, and the second limiting part 612 is located on the +Y axis side of the fourth terminal 134. The -Z axis side surface of the second limiting part 612 is the second guiding surface 6122, and the -Y axis side surface is the second force-applying surface 6121. The first guiding surface 6112 extends from the bottom surface 120f toward the top surface 120e and is inclined towards the right side surface 120d. The second guiding surface 6122 extends from the bottom surface 120f toward the top surface 120e and is inclined towards the left side surface 120c. In this embodiment, the first terminal 131 and the fourth terminal 134 are auxiliary contact terminals, and the second terminal 132, the third terminal 133, and the fifth terminal 135 are direct contact terminals.

[0201] Correspondingly, such as Figure 15 As shown, the third hole 123 is located on the -Y axis side of the first terminal 131, and the fourth hole 124 is located on the +Y axis side of the fourth terminal. The first mounting hole and the second mounting hole are the third hole 123 and the fourth hole 124, respectively. The third hole 123 and the fourth hole 124 cooperate with the first limiting part 611 and the second limiting part 612, respectively, to limit the chip 30 in the Y-axis direction and / or the Z-axis direction.

[0202] The first limiting part 611 and the second limiting part 612 limit the chip 30 in the Y-axis direction. Specifically, the first limiting part 611 prevents the chip 30 from shifting in the -Y-axis direction, and the second limiting part 612 prevents the chip 30 from shifting in the +Y-axis direction.

[0203] During the installation process of the ink cartridge equipped with the chip 30 and chip holder 20 provided in this embodiment, the first limiting part 611 contacts the +Y axis side surface of the first connecting part 911a of the first contact pin 911 and presses the first contact pin 911 in the -Y axis direction, causing the first connecting part 911a of the first contact pin 911 to deflect in the +Y axis direction; the second limiting part 612 contacts the +Y axis side surface of the first connecting part 914a of the fourth contact pin 914 and presses the fourth contact pin 914 in the -Y axis direction, causing the first connecting part 914a of the fourth contact pin 914 to deflect in the -Y axis direction. This results in the distance in the Y axis direction between the contact part C of the first terminal 131 and the contact part C of the fourth terminal 134 in the installed state being smaller than the distance in the Y axis direction between the first contact pin 911 and the fourth contact pin 914 in the natural state. The advantage of this design is that it allows for a compact arrangement of the terminals 31, which is beneficial for miniaturizing the chip 30.

[0204] In the installed state, at least a portion of the contact portion C of the first terminal 131 and / or at least a portion of the contact portion C of the fourth terminal 134 coincides with at least a portion of the contact portion C of the third terminal 133 in the Y-axis direction.

[0205] It should be noted that the first limiting part 611 and the second limiting part 612 can also be respectively disposed on both sides of any other two terminals, such as on the -Y axis side of the second terminal 132 and the +Y axis side of the third terminal 133 respectively, and the second terminal 132 is pressed in the +Y axis direction and the third terminal 133 is pressed in the -Y axis direction respectively, so that the distance between the contact part C of the second terminal 132 and the contact part of the third terminal 133 in the Y axis direction is less than the distance between the second contact pin 912 and the third contact pin 913 in the Y axis direction in the natural state, thereby achieving the beneficial effects of reasonable terminal arrangement and chip miniaturization.

[0206] Example 5

[0207] The difference between this embodiment and the above embodiment is that the structure of the first limiting part 611 is different.

[0208] refer to Figure 17 , Figure 18 , Figure 19 and Figure 20 As shown, in this embodiment, the guiding component includes a first guiding structure 61, which includes a first limiting part 611. The first limiting part 611 is connected to the chip socket 20. The first limiting part 611 has a first connecting end connected to the chip socket 20 and a first protruding end opposite to the first connecting end. The first protruding end has a first driving surface 314 facing the auxiliary contact terminal. The force-applying part includes the first driving surface 314. And in the extension direction from the first connecting end to the first protruding end, the first driving surface 314 gradually moves away from the auxiliary contact terminal.

[0209] In this embodiment, the first terminal 131, the second terminal 132, the third terminal 133, the fourth terminal 134, and the fifth terminal 135 are all disposed on the side of the chip 30 facing away from the chip holder 20, and the contact portions of the first terminal 131 to the fifth terminal 135 are in the same plane. Since the dimensions of the first terminal 131 to the fifth terminal 135 are also relatively similar, their lengths in the Z-axis direction are all greater than their lengths in the Y-axis direction. Even a small offset of the ink cartridge in the Y-direction could affect the electrical connection between the terminal 31 and the graphic generation device, causing the ink cartridge to malfunction. This embodiment effectively restricts the movement of the chip 30 in the Y-direction through the first limiting part 611.

[0210] Terminal 31 is disposed on the outer surface 321a. At least one of the multiple terminals 31 is an auxiliary contact terminal, and the remaining terminals 31 are direct contact terminals. During cartridge installation, the direct contact terminal can directly contact the corresponding contact pin 91, while the auxiliary contact terminal requires the guidance of a guide component to deform the corresponding contact pin 91 before it can contact the auxiliary contact terminal, thereby ensuring a stable electrical connection between the auxiliary contact terminal and the contact pin 91.

[0211] The projection of the contact portion of at least one auxiliary contact terminal onto the first imaginary line S1 coincides with the projection of the contact portion of a direct contact terminal or auxiliary contact terminal onto the first imaginary line S1.

[0212] refer to Figure 18 , Figure 19 , Figure 20 and Figure 21 As shown, in this embodiment, the contact portion of the direct contact terminal and the contact portion of the auxiliary contact terminal are arranged in two rows. The contact portions of the terminals 31 in the same row are arranged along the first imaginary line S1, which is a straight line parallel to the outer surface 321a.

[0213] In this embodiment, the first mounting hole is the third hole 123, the first terminal 131 serves as an auxiliary contact terminal, and the first driving surface 314 is used to guide the first contact pin 911 to deform and contact the first terminal.

[0214] The side of the first driving surface 314 that is away from the outer surface 321a is called the first side 314a, and the side of the first driving surface 314 that is close to the outer surface 321a (equivalent to the front surface 120a in Embodiment 1) is called the second side 314b. The distance from the first side 314a to the corresponding auxiliary contact terminal is greater than the distance from the second side 314b to the corresponding auxiliary contact terminal.

[0215] This embodiment applies to the second type of ink cartridge. During the process of installing the ink cartridge into the mounting part 90, the contact pin 91 that abuts against the auxiliary contact terminal first acts on the first protruding end. Under the action of the first driving surface 314, the first contact pin 911 deforms. Specifically, the first connecting part 911a of the first contact pin 911 deflects toward the auxiliary contact terminal and gradually approaches the auxiliary contact terminal under the guidance of the first driving surface 314 until it contacts the auxiliary contact terminal.

[0216] This example effectively suppresses the deformation of the first stylus 911 in the -Y direction by using the guiding effect of the first driving surface 314.

[0217] If the projection of the contact portion of the auxiliary contact terminal on the first imaginary line S1 coincides with the projection of the contact portion of a direct contact terminal or auxiliary contact terminal on the first imaginary line S1, then the first contact pin 911 can achieve a larger deformation amplitude in the Y direction when the ink cartridge is installed, thereby having a better suppression effect on the offset of the ink cartridge in the Y direction.

[0218] refer to Figure 20 , Figure 21 , Figure 22 and Figure 23 As shown, during the installation process, one end of the ink cartridge first engages with the recessed portion on the inner wall of the mounting part 90 using the protrusion 14. Then, the other end of the ink cartridge rotates along the installation direction R and is stably engaged with the rotating part 93 on the mounting part 90 using the retractable engaging member 15. This ensures the electrical connection between the chip 30 and the contact pin 91, while also ensuring the alignment connection between the ink outlet 13 and the ink supply part 92. In this example, the installation direction R intersects with the outer surface 321a parallel to the YZ plane.

[0219] refer to Figure 22 As shown, in this example, the first direction is the direction indicated by the Z-axis, and the first direction is different from the installation direction R.

[0220] In one possible implementation method, refer to Figure 24 As shown, the ink cartridge is an ink pouch type ink cartridge, and its installation direction Q intersects with the YZ plane. Therefore, the outer surface 321a is inclined relative to the installation direction Q, and the base 910 of the corresponding mounting part 90 also adopts a corresponding inclined setting to achieve a stable connection.

[0221] refer to Figure 24 As shown, in this example, the first direction is the direction indicated by the Z-axis, and there is an angle between the first direction and the mounting direction Q.

[0222] In one possible implementation, there may be one or two auxiliary terminals.

[0223] In one possible implementation, this embodiment uses the first terminal 131 and the second terminal 132 as auxiliary contact terminals, and the third terminal 133, the fourth terminal 134, and the fifth terminal 135 as direct contact terminals. Furthermore, the first contact pin 911 corresponding to the first terminal 131 and the second contact pin 912 corresponding to the second terminal 132 deflect in opposite directions after elastic deformation. Therefore, the offset of the ink cartridge in both the +Y and -Y directions can be effectively suppressed, ensuring the stability of the connection between the terminals of the chip 30 and each contact pin 91.

[0224] The contact portions C of the second terminal 132, the third terminal 133, and the fifth terminal 135 are located in the first row, i.e., all on the straight line L3. The contact portions C of the fourth terminal 134 and the first terminal 131 are located in the second row, i.e., all on the straight line L4. In this embodiment, the first imaginary line S1, the straight lines L3 and L4 are all parallel to the Y-axis.

[0225] To make the projection of the contact portion of the auxiliary contact terminal on the first imaginary line S1 coincide with the contact portion of the other terminal, the contact pin corresponding to the auxiliary contact terminal needs to undergo a greater deformation in the ink cartridge installation state.

[0226] refer to Figure 17 , Figure 18 , Figure 19 and Figure 20 As shown, to improve the positioning and mounting effect of the chip 30, a splicing part 315 is also connected between the first protruding end and the first connecting end of the first limiting part 611. The side of the splicing part 315 partially fits against the side of the first mounting hole, and the end face of the splicing part 315 away from the receiving part 22 is flush with the outer surface 321a. The splicing part 315 can enhance the connection and fit between the chip holder 20 and the chip 30, and can also fill the first mounting hole on the chip 30 to a certain extent, making the chip 30 more complete in appearance.

[0227] The side of the first protruding end facing away from the first driving surface 314 is a first inclined surface 316, and the two ends of the first driving surface 314 and the first inclined surface 316 are connected by a second inclined surface 317. The second imaginary line S2 is parallel to the outer surface 321a and perpendicular to the first imaginary line S1. The projection of the second inclined surface 317 onto the outer surface 321a has a guide side 318 that intersects both the first imaginary line S1 and the second imaginary line S2.

[0228] The first limiting part 611, including the first inclined surface 316 and the second inclined surface 317, is applicable not only to the aforementioned second type of ink cartridge but also to the first type of ink cartridge.

[0229] When the ink cartridge provided in this embodiment is installed with the second imaginary line S2 as the installation direction, the stylus corresponding to the auxiliary contact terminal undergoes elastic deformation under the guidance of the second inclined surface 317 and gradually approaches the auxiliary contact terminal. Specifically, the stylus 91 gradually approaches the auxiliary contact terminal, and the first connecting part 911a or the second connecting part 911b also gradually deflects toward the auxiliary contact terminal until it contacts the auxiliary contact terminal.

[0230] In one possible implementation, this embodiment has two auxiliary contact terminals: a first terminal 131 and a second terminal 132. The first guiding structure 61 further includes a second limiting portion 612, which is connected to the chip socket 20. The second limiting portion 612 has a second connecting end connected to the chip socket 20 and a second driving end opposite to the second connecting end. The second driving end has a second driving surface 319 facing the auxiliary contact terminal, and the force-applying portion includes the second driving surface 319; and in the extending direction from the second connecting end to the second driving end, the second driving surface gradually moves away from the auxiliary contact terminal.

[0231] The first contact pin 911 corresponding to the first terminal 131 and the second contact pin 912 corresponding to the second terminal 132 deflect in opposite directions after elastic deformation. Therefore, the offset of the ink cartridge in the +Y and -Y directions can be effectively suppressed, ensuring the stability of the connection between the terminal of the chip 30 and each contact pin 91.

[0232] To make the projections of the contact portions of the two auxiliary terminals on the first imaginary line S1 coincide, two terminals in different rows that are close to each other in the Y direction can be selected as auxiliary terminals. For example, the first terminal 131 and the third terminal 133 can be used as auxiliary terminals, or the third terminal 133 and the fourth terminal 134 can be used as auxiliary terminals.

[0233] Example 6

[0234] refer to Figure 25 , Figure 26 As shown, the difference between this embodiment and the above embodiment is that the number and arrangement of terminals 31 on the chip 30 are different.

[0235] In one possible implementation, the plurality of terminals 31 are designated as a first terminal 131, a second terminal 132, a third terminal 133, a fourth terminal 134, a fifth terminal 135, a sixth terminal 136, a seventh terminal 137, an eighth terminal 138, and a ninth terminal 139. (See reference) Figure 26 and Figure 27 As shown, there are nine corresponding contact pins 91, namely the first contact pin 911, the second contact pin 912, the third contact pin 913, the fourth contact pin 914, the fifth contact pin 915, the sixth contact pin 916, the seventh contact pin 917, the eighth contact pin 918, and the ninth contact pin 919.

[0236] The second terminal 132, also known as the reset terminal, is used to reset the data inside the wafer.

[0237] The third terminal 133, i.e. the clock terminal, is used to receive clock signals;

[0238] The sixth terminal 136, the power supply terminal, is used to receive a power supply potential different from the ground potential, such as 3.6V or 3.3V, and provides power for the operation of the memory through this terminal.

[0239] The seventh terminal, 137, is the grounding terminal: used to receive grounding potential and transmit grounding signals;

[0240] The eighth terminal 138, i.e. the data terminal, is used for sending or receiving data signals.

[0241] The first terminal 131 and the fourth terminal 134, namely the low-voltage detection terminals, are terminals to which a low voltage is applied. They can detect whether a short circuit has occurred in the chip 30. Specifically, they detect whether a short circuit has occurred between the chip itself and the high-voltage detection terminal, and also have an installation detection function. The low voltage can be 3.3V or 3.6V, which is basically the same as or slightly lower than the operating voltage of the memory.

[0242] Terminals 135 (fifth terminal) and 139 (ninth terminal) are high-voltage detection terminals, respectively, which are terminals to which high voltage is applied and have installation detection functions. High voltage is a voltage higher than the operating voltage of the memory, such as 42V or 40V.

[0243] Each terminal 31 has the same structure, and each terminal has a contact portion. The contact portion is the most likely contact area of ​​the stylus 91 on the terminal when the ink cartridge is installed on the graphics generating device.

[0244] In this embodiment, the multiple terminals 31 can be arranged in two rows, with four terminals 31 arranged in the first row and five terminals 31 arranged in the second row.

[0245] refer to Figure 27 , Figure 28 , Figure 29 and Figure 30 As shown, the first mounting hole may be formed between two adjacent terminals in the first row, or the first mounting hole may be formed at the edge of the substrate 120 and extend to the terminal position located at the edge of the first row; the second mounting hole may be formed between two adjacent terminals in the second row, or the second mounting hole may be formed at the edge of the substrate 120 and extend to the terminal position located at the edge of the second row.

[0246] In this embodiment, the structures of the first limiting part 611 and the second limiting part 612 are the same as those in the above embodiment, and will not be described again here.

[0247] In this example, the first limiting part 611 and the second limiting part 612 can be located on both sides of any two terminals 31, for example, as shown. Figure 28 , Figure 29 and Figure 30 As shown, the fifth contact pin 915 is pressed towards the +Y axis side of the fifth terminal 135 and the first contact pin 911 is pressed towards the -Y axis side of the first terminal 131, respectively. This makes the distance between the contact portion C of the fifth terminal 135 and the contact portion C of the first terminal 131 in the Y axis direction smaller than the distance between the fifth contact pin 915 and the first contact pin 911 in the Y axis direction under normal conditions. This achieves the beneficial effect of reasonable terminal arrangement and miniaturization of chip 30.

[0248] By applying opposite forces along the Y-axis or opposite forces along the Z-axis to the chip 30 via the first limiting part 611 and the second limiting part 612, the positioning effect of the chip 30 can be improved, preventing the position of the chip 30 from shifting. This makes the electrical contact between the terminal 31 of the chip 30 and the contact pin 91 in the mounting part 90 of the graphics generating device more stable.

[0249] refer to Figure 25 , Figure 31 and Figure 32 As shown, in this example, the first limiting part 611 and the second limiting part 612 can be located on both sides of any two terminals 31, for example, on the -Y axis side of the fourth terminal 134 and the +Y axis side of the ninth terminal 139, respectively. The ninth contact pin 919 is pressed in the -Y axis direction and the fourth contact pin 914 is pressed in the +Y axis direction, so that the distance between the contact part C of the ninth terminal 139 and the contact part C of the fourth terminal 134 in the Y axis direction is less than the distance between the ninth contact pin 919 and the fourth contact pin 914 in the Y axis direction under normal conditions, thereby achieving the beneficial effect of reasonable terminal arrangement and miniaturization of chip 30.

[0250] like Figure 25 , Figure 31 , Figure 32 As shown, terminal 134 (fourth terminal) and terminal 139 (ninth terminal) are auxiliary contacts, while the remaining terminals are direct contacts. Figure 28 , Figure 29 and Figure 30 As shown, the first terminal 131 and the fifth terminal 135 are auxiliary contact terminals, and the remaining terminals are direct contact terminals.

[0251] Example 7

[0252] refer to Figure 33 , Figure 34 , Figure 35 and Figure 36As shown, in this embodiment, the guiding component includes a second guiding structure 62, the second guiding structure 62 includes a first guiding groove 621 formed in the chip 30, the force application part includes the first guiding groove 621, and the first guiding groove 621 extends from one side edge of the chip 30 to the auxiliary contact terminal.

[0253] In one possible implementation, the first guide groove 621 is located on the -Z axis side of any terminal on the substrate 120, penetrating the bottom surface 120f and the top surface 120e of the substrate 120, and extending obliquely towards the right side surface 120d. The left side wall of the first guide groove 621 is the third guide surface 603a, and the upper wall is the third limiting surface 603b. For example, the first guide groove 621 is located on the -Z axis side of the fourth terminal 134 on the substrate 120, penetrating the bottom surface 120f and the top surface 120e of the substrate 120, and extending obliquely towards the right side surface 120d. The left side wall of the first guide groove 621 is the third guide surface 603a, and the upper wall is the third limiting surface 603b.

[0254] In one possible implementation, there are two auxiliary contact terminals, namely a first auxiliary contact terminal (fourth terminal 134) and a second auxiliary contact terminal (ninth terminal 139). On the front surface, the projection portions of the contact portions of the two auxiliary contact terminals on the first plane overlap.

[0255] The second guiding structure 62 also includes a second guiding groove 622 formed in the chip 30. The first guiding groove 621 and the second guiding groove 622 extend from the edge of the chip 30 to two auxiliary contact terminals respectively, that is, the first guiding groove 621 and the second guiding groove 622 extend to the first auxiliary contact terminal (fourth terminal 134) and the second auxiliary contact terminal (ninth terminal 139) respectively.

[0256] In one possible implementation, the second guide structure 62 includes a first guide groove 621 and a second guide groove 622. The second guide groove 622 is located in the -Z-axis direction of any terminal on the substrate 120, extending from the bottom surface 120f to the top surface 120e and inclined towards the left side surface 120c. The right side wall of the second guide groove 622 is a fourth guide surface 604a, and the upper wall is a fourth limiting surface 604b. For example, the second guide groove 622 is located in the -Z-axis direction of the ninth terminal 139 on the substrate 120. The second guide groove 622 extends from the bottom surface 120f to the top surface 120e of the substrate 120 and inclined towards the left side surface 120c. Its right side wall is a fourth guide surface 604a, and its upper wall is a fourth limiting surface 604b.

[0257] In one possible implementation, the first guide groove 621 and the second guide groove 622 are interconnected. Specifically, the -Z-axis side of the first guide groove 621 may be connected to the +Z-axis side of the second guide groove 622.

[0258] In this embodiment, the first auxiliary contact terminal is the fourth terminal 134, and the second auxiliary contact terminal is the ninth terminal 139.

[0259] During the process of loading the printing consumables provided in this embodiment into the mounting part 90 of the graphic generation device, the fourth guide surface 604a guides the ninth contact pin 919 to move to the fourth limiting surface 604b, and presses the first connecting part 919a of the ninth contact pin 919 in the -Y axis direction, causing it to deflect in the -Y axis direction, until the third limiting surface 603b also abuts against the ninth contact pin 919. At this time, the ninth contact pin 919 can simultaneously prevent the chip 30 from shifting in the -Y axis direction and the -Z axis direction in the installed state.

[0260] Simultaneously, the third guiding surface 603a guides the fourth contact pin 914 to move to the third limiting surface 603b, and presses the first connecting portion 914a of the fourth contact pin 914 in the +Y axis direction, causing it to deflect in the +Y axis direction until the third limiting surface 603b abuts against the fourth contact pin 914. At this time, the fourth contact pin 914b can simultaneously prevent the chip 30 from shifting in the +Y axis direction and the -Z axis direction in the installed state. Therefore, in this embodiment, both the first guiding groove 621 and the second guiding groove 622 can limit the chip 30 in the Z axis direction and the Y axis direction.

[0261] In this embodiment, the contact portion C of the fourth terminal 134 may be disposed at at least one of the front surface 120a, the third limiting surface 603b, and the third guiding surface 603a of the substrate 120, and the contact portion C of the ninth terminal 139 may be disposed at at least one of the front surface 120a, the fourth guiding surface 604a, and the fourth limiting surface 604b of the substrate 120.

[0262] In one possible implementation, at least a portion of the contact portion C of the fourth terminal 134 and the contact portion C of the ninth terminal 139 are projected onto the first plane (XY plane).

[0263] When the ink cartridge is installed, due to the aforementioned deflection of the fourth contact pin 914 and the ninth contact pin 919, the distance along the Y-axis between the contact portion C of the fourth terminal 134 and the contact portion C of the ninth terminal 139 is smaller than the distance along the Y-axis between the fourth contact pin 914 and the ninth contact pin 919 in their natural state. This allows for a compact terminal arrangement, which is beneficial for miniaturizing the chip 30.

[0264] Similarly, the first guide groove 621 and the second guide groove 622 can be located on either side of any other terminal. For example, the first guide groove 621 can be located on the -Z axis side of the second terminal 132, and the second guide groove 622 can be located on the -Z axis side of the seventh terminal 137, etc.

[0265] Furthermore, in this embodiment, the number and specific shape of the guide grooves are not subject to excessive restrictions. Specifically, the chip 30 may only have a first guide groove 621 or only a second guide groove 622. The first guide groove 621 and / or the second guide groove 622 may be configured as a tortuous extension or other regular or irregular shape.

[0266] In some possible implementations, at least one of the first guide groove 621 and the second guide groove 622 may be disposed on the chip holder 20 or on the housing 10.

[0267] Example 8

[0268] refer to Figure 37 , Figure 38 , Figure 39 and Figure 40 As shown, the difference between this embodiment and embodiment seven is that the first guide groove 621 is disposed on the -Z axis side of the first terminal 131, and the second guide groove 622 is disposed on the -Z axis side of the fifth terminal 135.

[0269] In this embodiment, the first guide groove 621 is a recessed portion extending from the bottom surface 120f to the top surface 120e and inclined towards the left side surface 120c, with its right side wall being the third guide surface 603a and its upper wall being the third limiting surface 603b. The second guide groove 622 is a recessed portion extending from the bottom surface 120f to the top surface 120e and inclined towards the right side surface 120c, with its left side wall being the fourth guide surface 604a and its upper wall being the fourth limiting surface 604b.

[0270] During the process of loading the printing consumables provided in this embodiment into the mounting part 90 of the graphic generation device, the third guide surface 603a guides the first stylus 911 into the first guide groove 621 and presses the first connecting part 911a of the first stylus 911 in the -Y axis direction, causing it to deflect in the -Y axis direction until the third limiting surface 603b also abuts against the first stylus 911. At this time, the ninth stylus 919 can simultaneously prevent the chip 30 from shifting in the -Y axis direction and the -Z axis direction in the installed state.

[0271] Simultaneously, the third guiding surface 603a guides the fifth contact pin 915 into the second guiding groove 622, and presses the first connecting portion 915a of the fifth contact pin 915 in the +Y axis direction, causing it to deflect in the +Y axis direction until the fourth limiting surface 604b abuts against the fifth contact pin 915. At this time, the fifth contact pin 915b can simultaneously prevent the chip 30 from shifting in the +Y axis direction and the -Z axis direction in the installed state. Therefore, in this embodiment, both the first guiding groove 621 and the second guiding groove 622 can limit the chip in the Z axis direction and the Y axis direction.

[0272] It should be noted that, in this embodiment, the contact portion C of the first terminal 131 can be disposed at at least one of the front surface 120a, the third limiting surface 603b, and the third guiding surface 603a of the chip substrate 120, and the contact portion C of the fifth terminal 135 can be disposed at at least one of the front surface 120a, the fourth limiting surface 604b, and the fourth guiding surface 604a of the chip substrate 120.

[0273] In one possible implementation, at least a portion of the contact portion C of the first terminal 131 and the contact portion C of the fifth terminal 135 on the surface of the substrate 120 are projected to coincide in the XY plane.

[0274] When the ink cartridge is installed, due to the aforementioned deflection of the first contact pin 911 and the fifth contact pin 915, the distance along the Y-axis between the contact portion C of the first terminal 131 and the contact portion C of the fifth terminal 135 is smaller than the distance along the Y-axis between the first contact pin 911 and the fifth contact pin 915 in their natural state. This allows for a compact terminal arrangement, which is beneficial for miniaturizing the chip 30.

[0275] Each terminal 31 has a contact portion for electrical contact with the stylus 91, and the plurality of terminals 31 are arranged in two rows spaced apart from each other along a first direction. In one possible implementation, on the front surface, the contact portion of the auxiliary contact terminal coincides with the projection of the contact portion of at least one of the remaining terminals 31. The two auxiliary contact terminals may be the first terminal 131, and the contact portions C of the first terminal 131 and the contact portion C of the fifth terminal 135 may at least partially coincide in the XY plane.

[0276] Example 9

[0277] refer to Figure 41 , Figure 42 , Figure 43 and Figure 44 As shown, the difference between this embodiment and embodiments seven and eight is that the number and arrangement of the multiple terminals 31 on the chip 30 are different. In this embodiment, the chip 30 has five terminals 31, and the number and arrangement of the multiple terminals 31 are the same as those of the terminals 31 on the chip 30 in embodiments one to five.

[0278] In this embodiment, the first guide groove 621 is disposed on the -Z axis side of the first terminal 131, and the second guide groove 622 is disposed on the -Z axis side of the second terminal 132.

[0279] In this embodiment, the first auxiliary contact terminal is the first terminal 131, and the second auxiliary contact terminal is the second terminal 132.

[0280] In this embodiment, the first guide groove 621 is a recessed portion extending from the bottom surface 120f to the top surface 120e and inclined towards the left side surface 120c, with its right side wall being the third guide surface 603a and its upper wall being the third limiting surface 603b. The second guide groove 622 is a recessed portion extending from the bottom surface 120f to the top surface 120e and inclined towards the right side surface 120c, with its left side wall being the fourth guide surface 604a and its upper wall being the fourth limiting surface 604b.

[0281] During the process of loading the printing consumables provided in this embodiment into the mounting part 90 of the graphic generation device, the third guide surface 603a guides the first stylus 911 into the first guide groove 621 and presses the first connecting part 911a of the first stylus 911 in the -Y axis direction, causing it to deflect in the -Y axis direction until the third limiting surface 603b also abuts against the first stylus 911. At this time, the second stylus 912 can simultaneously prevent the chip 30 from shifting in the -Y axis direction and the -Z axis direction in the installed state.

[0282] Simultaneously, the fourth guiding surface 604a guides the second contact pin 912 into the second guiding groove 622, and presses the first connecting portion 912a of the second contact pin 912 in the +Y axis direction, causing it to deflect in the +Y axis direction until the fourth limiting surface 604b abuts against the second contact pin 912. At this time, the second contact pin 912 can simultaneously prevent the chip 30 from shifting in the +Y axis direction and the -Z axis direction in the installed state. Therefore, in this embodiment, both the first guiding groove 621 and the second guiding groove 622 can limit the chip in the Z axis direction and the Y axis direction.

[0283] Example 10

[0284] refer to Figure 45 , Figure 46 , Figure 47 and Figure 48 As shown, in this embodiment, a guide rail 11 is provided on the side of the housing 10 facing the chip holder 20, and the chip holder 20 is provided with a splicing part 23 that slides with the guide rail 11. This allows the chip holder 20 to be connected to the housing 10, and the chip holder 20 to move relative to the housing 10 along the guide rail 11.

[0285] The chip holder 20 is positioned on the front surface of the housing 10. The chip holder 20 also includes a limiting block 24 located at the splicing section 23. The limiting block 24 is configured to engage with the guide rail 11, restricting the movement of the chip holder 20 relative to the housing 10. The guide rail 11 extends in a direction intersecting with the first and second directions and is parallel to the front surface 120a.

[0286] In this embodiment, the guiding component includes a third guiding structure 63, which includes a third limiting part 631 disposed in the housing 10. A clearance hole 21 is provided in the chip holder 20, and a third mounting hole is provided in the chip 30. The third limiting part 631 extends through the clearance hole 21 and the third mounting hole and protrudes from the side of the chip 30 facing away from the chip holder 20. The side of the third limiting part 631 facing the auxiliary terminal is a fifth limiting surface 6311, and the force-applying part includes the fifth limiting surface 6311.

[0287] By having the third limiting part 631 pass through the clearance hole 21, the positioning and installation effect of the chip holder 20 can be improved. By having the third limiting part 631 pass through the third mounting hole, the positioning and installation effect of the chip 30 can be improved.

[0288] In one possible implementation, the housing 10 and the third limiting part 631 are connected by a moving block 54. The third limiting part 631 is connected to the end of the moving block 54 facing away from the housing 10. By setting the moving block 54, the chip holder 20 can be positioned and the clearance hole 21 can be blocked, thereby improving the overall integrity.

[0289] In one possible implementation, the fifth limiting surface 6311 is an inclined plane.

[0290] In one possible implementation, the third guiding structure 63 further includes a fourth limiting part 632, which is disposed on the housing 10 or the chip holder 20. The chip 30 has a fourth mounting hole, and the fourth limiting part 632 extends through the fourth mounting hole to the side of the chip 30 facing away from the chip holder 20. The side of the fourth limiting part 632 facing the auxiliary terminal is a sixth limiting surface 6321, and the force-applying part includes the sixth limiting surface 6321.

[0291] In one possible implementation, there are two auxiliary contact terminals, and the sixth limiting surface 6321 is configured to abut against the two contact pins 91 respectively with the fifth limiting surface 6311, so that the two contact pins 91 are deformed in opposite and mutually close directions and abut against the two auxiliary contact terminals respectively, and the projection portions of the contact portions of the two auxiliary contact terminals on the first plane on the front surface 120a coincide.

[0292] refer to Figure 47 , Figure 52 and Figure 53 As shown, the chip holder 20 also includes a lower part 25. The chip holder 20 has an abutment surface 25a. The lower part 25 is disposed on the -Z axis side of the chip holder 20. When the ink cartridge is installed from the opening 95 to the mounting part 90 along the mounting direction P, the abutment surface 25a abuts against the step 94 in the mounting part 90, so that the chip holder 20 can move relative to the cartridge body 10.

[0293] Specifically, refer to Figure 47 , Figure 52 and Figure 53 As shown, the abutment surface 25a is located on the -Z axis side of the lower part 25. The abutment surface 25a abuts against the step 94 in the mounting part 90 and drives the chip holder 20 to move. The shape of the abutment surface 25a is not limited. For example, it can be set as a plane, a curved surface, an irregular concave-convex surface, etc., as long as it can satisfy the function of abutting against the step 94 in the mounting part 90.

[0294] During the installation of the printing consumables into the mounting section 90, the chip holder 20 moves at least in the second direction (Y-axis direction). The contact between the auxiliary contact terminals (first terminal 131 and second terminal 132) and the contact pin 91 is delayed compared to the contact between the third limiting part 631 and the fourth limiting part 632 and the contact pin 91. This ensures that the corresponding contact pin is first pressed in the Y-axis direction, and then the terminal contacts the corresponding contact pin, preventing the first contact pin 911 and the second contact pin 912 from retracting into the base 910 towards the -X-axis before they are pressed.

[0295] refer to Figure 48 , Figure 49 and Figure 50 As shown, the side of the substrate 120 facing away from the chip holder 20 is the outer surface 321a, which is parallel to the YZ plane. Multiple terminals 31 are disposed on the outer surface 321a. The third mounting hole is a notch extending from the edge of the substrate 120 to the auxiliary contact terminal.

[0296] In this embodiment, the first terminal 131 and the second terminal 132 are used as auxiliary contact terminals, and the third terminal 133, the fourth terminal 144, and the fifth terminal 145 are used as direct contact terminals. Furthermore, the corresponding styluses of the first terminal 131 and the second terminal 132 deflect in opposite directions after elastic deformation. Therefore, the offset of the ink cartridge in both width directions, namely ±Y, can be effectively suppressed, and the electrical connection assembly 300 as a whole has good connection stability with the stylus holder 91.

[0297] refer to Figure 51 , Figure 52 , Figure 53 As shown, during the contact process between the printing consumables provided in this embodiment and the stylus 91 inside the mounting portion 90, the ink cartridge is installed into the mounting portion 90 from the opening 95 along the mounting direction P. In this embodiment, the mounting direction P is along the Z-axis. The ink cartridge is installed into one of the mounting positions of the mounting portion 90 along the -Z-axis direction. At this time, the chip 30 is relative to the position of the stylus inside the mounting portion 90, and the movement trajectory of the synchronous chip holder 20 and the ink cartridge approaches the stylus approximately along the -Z-axis direction.

[0298] At this time, the first contact pin 911 and the second contact pin 912 do not move much in the X direction, especially not in the +X direction. Reducing the movement of the first contact pin 911 and the second contact pin 912 in the X direction helps to ensure that the first contact pin 911 and the second contact pin 912 can be better guided along the fifth limiting surface 6311 and the sixth limiting surface 6321 respectively to abut against the first terminal 131 and the second terminal 132.

[0299] Meanwhile, in order to ensure stable contact with the third terminal 133, the fourth terminal 134, and the fifth terminal 135 respectively, the third contact pin 913, the fourth contact pin 914, and the fifth contact pin 915 abut against the substrate 120, and can generate movement / deformation along the +X axis direction.

[0300] After the ink cartridge moves a certain distance along the -Z axis, the lower portion 25 on the chip holder 20 abuts against the inner step 94 of the mounting portion 90. This abutment can occur via the abutting surface 25a of the lower portion 25 against the inner step 94 of the mounting portion 90. At this point, the ink cartridge is not yet fully installed, and the terminals 31 on the chip 30 and the contact pins 91 are not yet in contact. The ink cartridge continues to move along the -Z axis. (Reference) Figure 46 , Figure 47 , 48 As shown, since the housing 10 is provided with a guide rail 11, which engages with the splicing part 23 on the chip holder 20, the chip holder 20 is connected to the housing 10. The limiting block 24 is engaged with the guide rail 11, so that the chip holder 20 can move relative to the housing 10 along the guide rail 11.

[0301] In one possible implementation, the housing 10 and the third limiting part 631 are connected by a movable block 54, which engages with the clearance hole 21 of the chip holder 20, allowing the chip holder 20 to move relative to the housing 10 along the clearance hole 21. At this time, because the lower connecting part 25 on the chip holder 20 abuts against the inner step 94 of the mounting part 90, the chip holder 20 is subjected to an abutting force along the +Z axis, thus allowing the chip holder 20 to move relative to the housing 10 along the guide rail 11 and the clearance hole 21. In this embodiment, the movable directions of the guide rail 11 and the clearance hole 21 are the same, allowing the chip holder 20 to move relative to the housing 10 in an obliquely upward direction.

[0302] Because the substrate 120 has a first hole 121 and a second hole 122 through it, the first hole 121 is used to cooperate with the first positioning post 201 on the chip holder 20, and the second hole 122 is used to cooperate with the second positioning post 202 on the chip holder 20, so that the chip 30 is positioned and installed on the chip holder 20. At this time, the chip 30 is fixedly connected to the chip holder 20, that is, the chip 30 moves synchronously with the chip holder 20 relative to the housing 10 in an obliquely upward direction. Specifically, the chip 30 moves away from the ink outlet 13 on the housing 10 approximately along the trajectory S direction; the chip 30 moves closer to the handle 12 on the housing 10 approximately along the trajectory S direction; the trajectory S direction is a direction that includes components in the +Z axis direction and the +Y axis direction.

[0303] In one possible implementation, the chip 30 moves approximately in the +Y axis direction relative to the pins within the mounting portion 90.

[0304] In one possible implementation, a third limiting part 631 is disposed on the housing 10, and a fourth limiting part 632 is disposed on the housing 10 or the chip holder 20; the side of the third limiting part 631 facing the auxiliary contact terminal is a fifth limiting surface 6311, and the force-applying part includes the fifth limiting surface 6311; the side of the fourth limiting part 632 facing the auxiliary contact terminal is a sixth limiting surface 6321, and the force-applying part includes the sixth limiting surface 6321; the sixth limiting surface 6321 is configured to abut against the two contact pins 91 respectively with the fifth limiting surface 6311.

[0305] refer to Figure 48 , Figure 50 , Figure 53 As shown, the third guiding structure 63 also includes a fourth limiting part 632, which protrudes from the side of the chip 30 facing away from the chip holder 20. The side of the fourth limiting part 632 facing the auxiliary terminal is a sixth limiting surface 6321, which is used to guide the deformation of the contact pin 91 and make the contact pin 91 contact the auxiliary contact terminal.

[0306] In this embodiment, the first terminal 131 and the second terminal 132 are used as auxiliary contact terminals, and the third terminal 133, the fourth terminal 144, and the fifth terminal 145 are used as direct contact terminals. During the relative movement of the chip 30 synchronous chip holder 20 with the housing 10 along the obliquely upward direction, the chip 30 synchronous chip holder 20 moves relative to the contact pins inside the mounting portion 90 along the +Y axis direction, that is, it moves relative to the contact pins 91 inside the mounting portion 90 with the direct contact terminals along the +Y axis direction.

[0307] The first contact pin 911, which contacts the first terminal 131, deforms along the fifth limiting surface 6311 of the third limiting part 631 in the +Y axis direction, and the second contact pin 912, which contacts the second terminal 132, deforms along the sixth limiting surface 6321 of the fourth limiting part 632 in the +Y direction. That is, the deflection directions of the contact pins corresponding to the first terminal 131 and the second terminal 132 after elastic deformation are opposite. Therefore, the offset of the ink cartridge in both width directions, namely ±Y directions, can be effectively suppressed, so that the printing consumables as a whole have good connection stability with the contact pin 91. Since the contact pin 91 itself has elastic deformation in the Y direction when the ink cartridge is installed, the offset of the ink cartridge in the direction that aggravates the deformation trend of the contact pin in the Y direction can be effectively suppressed in both the ±Y and ±Y directions.

[0308] If the projection of the contact portion of at least one auxiliary contact terminal on the second imaginary line C coincides with the projection of the contact portion of a direct contact terminal or auxiliary contact terminal on the second imaginary line C, then the contact pin corresponding to the auxiliary contact terminal can achieve a large deformation amplitude in the Y direction when the ink cartridge is installed, thereby having a better suppression effect on the offset of the ink cartridge in the width direction.

[0309] After the ink cartridge continues to move a certain distance along the -Z axis, the ink cartridge is installed in place. At this time, the ink outlet 13 of the ink cartridge is fluidly connected to the ink supply part 92 in the mounting part 90, the ink cartridge handle 12 cooperates with the fixing part in the mounting part 90 to fix the ink cartridge to the mounting part 90, and the chip 30 is electrically connected to the contact pin 91 in the mounting part 90.

[0310] refer to Figure 48 and Figure 49 As shown, in this embodiment, when the ink cartridge is installed in place, the direct contact terminal directly contacts the contact pin 91 inside the mounting part 90. The contact pin 91 does not deflect and directly achieves electrical contact. At the same time, the contact pin 91 that contacts the auxiliary contact terminal deflects through the guiding effect of the third guiding structure 63, so that the side of the contact pin 91 contacts the auxiliary contact terminal. This can be achieved by the upper surface of the first connecting part of the contact pin 91, i.e., the side facing the -Z axis direction, abutting against the lower surface of the auxiliary contact terminal, i.e., the side facing the +Z axis direction.

[0311] At this time, on the front surface 120a of the substrate 120, the straight line along the Z-axis is defined as the first imaginary line C1, and the straight line along the Y-axis is defined as the second imaginary line C2. When the contact points of all terminals 31 on the chip 30 that contact the pins 91 are projected onto the second imaginary line C2 along the direction of the first imaginary line C1, since the terminals have a certain thickness, there is a certain distance difference in the X-axis direction between the contact points of the auxiliary contact terminals on the side facing the -Z-axis and the contact points of the direct contact terminals on the side facing the -X-axis. The projection points of the contact points of the auxiliary contact terminals fall on the second imaginary line C2, and the projection points of the contact points of the direct contact terminals fall outside the second imaginary line C2. The projection points of the contact points of the direct contact terminals and the second imaginary line C2 form a certain distance L in the front-back direction. This distance L is the thickness of the direct contact terminals. Because the upper surface of the first connecting part of the stylus, that is, the side facing the -Z axis direction, is inclined, it is beneficial to minimize the interaction force between the auxiliary contact terminal and the stylus when they come into contact. Unlike the direct contact terminal, it does not need to contact the stylus plane, thus avoiding squeezing the stylus in the X axis direction. This reduces the risk of the stylus being damaged due to squeezing forces in different directions when the auxiliary contact terminal contacts the stylus.

[0312] Example 11

[0313] In this embodiment, reference Figure 54 , Figure 55 and Figure 56 As shown, the chip 30 includes a main body 51 and an extension 52. At least some of the multiple terminals 31 are disposed on the main body 51, and auxiliary terminals are disposed on the extension 52.

[0314] In this embodiment, multiple terminals 31 are arranged in three rows at intervals along a first direction. At least some of the terminals 31 are disposed on the main body 51, and the extension 52 is provided with electrical contacts 521. The electrical contacts 521 are electrically connected to the main body 51. Specifically, the electrical contacts 521 are electrically connected to the inner terminals disposed on the main body 51, and the auxiliary contact terminals are electrical contacts 521. The inner terminals are interface points that do not contact the contact pins 91, but the inner terminals are electrically connected to the memory.

[0315] In one possible implementation method, refer to Figure 59 As shown, the extension 52 is integrally connected to one end of the main body 51.

[0316] In another possible implementation, refer to Figure 57 and Figure 58 As shown, the main body 51 and the extension 52 are separate structures, but are connected to each other.

[0317] In one possible implementation method, refer to Figure 62 and Figure 63As shown, the guiding assembly includes a fourth guiding structure 64, which includes a fifth limiting portion 642 disposed on the housing 10. The side of the fifth limiting portion 642 facing the auxiliary contact terminal is a seventh limiting surface 6421, and the force-applying portion includes the seventh limiting surface 6421. The base 910 has multiple slits, and the contact pin has a first connecting portion and a third connecting portion. The fifth limiting portion 642 is inserted into the slit adjacent to the contact pin 91 that contacts the auxiliary contact terminal, causing the third connecting portion to deform and contact the auxiliary contact terminal. The direct contact terminal contacts the first connecting portion of the corresponding contact pin 91. The contact portion of the auxiliary contact terminal coincides with the projection portion of the contact portion of at least one direct contact terminal on a first plane. Figure 62 yes Figure 59 The diagram shows another chip mounted on the printing consumable.

[0318] In one possible implementation, the seventh limiting surface 6421 is an inclined surface, and the distance between the seventh limiting surface 6421 and the electrical contact 521 gradually increases along the installation direction of the printing consumable, i.e., along the first direction.

[0319] In one possible implementation, a rectangular notch is provided at the upper left corner of the main body 51, i.e., the -Y axis side on the +Z axis side, which cooperates with the mounting position of the box 10, which is conducive to the precise positioning and installation of the main body 51 and the extension 52.

[0320] In this embodiment, the main body 51 of the chip 30 has four positioning holes, namely a first hole 121, a second hole 122, a third hole 123 and a fourth hole 124. The first hole 121, the second hole 122, the third hole 123 and the fourth hole 124 are all through holes that penetrate the front surface 120a and the rear surface of the substrate 120 of the main body 51.

[0321] The first hole 121 is a through hole near the top surface 120e, the second hole 122 is a through hole near the bottom surface 120f, and the third hole 123 and the fourth hole 124 are respectively located on the left side surface 120c and the right side surface 120d, forming an arc-shaped recess. The mounting part for mounting the printing consumables provided in this embodiment includes positioning posts that protrude and engage with the first hole 121, the second hole 122, and the third hole 123, respectively. The chip 30 is then fixed to the housing 10 by welding with a hot soldering head to prevent the chip 30 from shifting in position relative to the ink cartridge along the Y-axis or Z-axis direction during installation or use after installation.

[0322] The extension 52 can perform the function of at least one of the data terminal, clock terminal, power terminal, reset terminal and ground terminal on the original chip.

[0323] refer to Figure 55 and Figure 56As shown, in this embodiment, the extension 52 is electrically connected to the memory of the chip 30 and the fourth contact pin 914 to realize the function of resetting the internal data of the memory of the chip 30.

[0324] In one possible implementation, the extension 52 includes an extension plate 522 and an electrical contact 521 connected to the extension plate 522. The extension plate 522 and the electrical contact 521 can be integrally formed or separately formed. The extension plate 522 is electrically connected to the electrical contact 521 and the memory of the chip 30.

[0325] The material of the extension plate 522 is not specifically limited. For example, the extension plate 522 can be made of a conductive material to ensure the stable electrical connection function of the extension portion 52, so that even if the electrical contact 521 is damaged, the extension plate 522 can still maintain the electrical connection function; the extension plate 522 can also be made of a partially conductive material, which can ensure both safety and the stable electrical connection function of the extension portion 52. The extension plate 522 can be made of a rigid material to ensure the structural fixation of the extension portion 52 and facilitate installation and positioning; it can also be made of a flexible material to allow the extension portion 52 to adapt to the structure of the box body 10 and be placed in different positions on the box body 10.

[0326] The connection method between the extension plate 522 and the electrical contact 521 and the main body 51 is not specifically limited, and the connection method between the extension plate 522 and the memory is not specifically limited. For example, the extension plate 522 can be connected to the memory through a conductive wire, or a separate conductive sheet can be provided on the main body 51, and the extension plate 522 can be connected to the memory through the conductive sheet.

[0327] In this embodiment, the extension plate 522 is connected to the conductive sheet 134A. The connection method between the extension plate 522 and the conductive sheet 134A is not limited. For example, the extension plate 522 can be made of a conductive material with a certain hardness and can be connected to the conductive sheet 134A by soldering. The position of the conductive sheet 134A on the substrate 120 is not limited. The conductive sheet 134A can be disposed on the rear surface 120b of the chip 30, located on a different surface of the substrate 120 from other terminals 31 on the chip 30. This ensures that the conductive sheet 134A will not short-circuit with other terminals 31, guarantees good grounding stability of the chip 30, and improves the safety of using the chip 30. In this embodiment, the conductive sheet 134A is disposed on the front surface 120a of the chip 30, facilitating the installation and connection of the extension plate 522 and the conductive sheet 134A.

[0328] refer to Figure 62 and Figure 63As shown, in this embodiment, the extended plate 522 is provided with a connector 523 for electrical connection with the memory; specifically, the connector 523 is electrically connected to the memory via a conductive sheet 134A. The connector 523 engages with the groove 503a on the mounting position, accurately installing and fixing the connector 523 to the corresponding position, making electrical contact with the conductive sheet 134A, thereby achieving electrical contact between the extended portion 52 and the memory, preventing external objects from damaging the connector 523 and affecting its conductivity.

[0329] The number, shape, and position of the connectors 523 on the extension plate 522 are not limited, and the number, shape, and position of the grooves 503a are set to correspond to the connectors 523.

[0330] In one possible implementation, the extension plate 522 is provided with perforated holes 524, which mate with protrusions 503b on the mounting position to accurately install the extension plate 522 into the corresponding position of the housing 10. The number, shape, and position of the protrusions 503b on the mounting position are not limited, while the number, shape, and position of the perforated holes 524 on the extension plate 522 are correspondingly provided to the protrusions 503b.

[0331] In this embodiment, two protrusions 503b are provided on the mounting position. The protrusions 503b protrude along the +X axis direction within the mounting position and are approximately cylindrical in shape. The extension plate 522 is provided with two hollow holes 524, which are approximately rectangular, to facilitate the installation of the protrusions 503b into the hollow holes 524 and to help accurately fix the protrusions 503b to the hollow holes 524.

[0332] Electrical contact 521 electrically connects the extension plate 522 and the contact pin 91. Electrical contact 521 is made of conductive material. Electrical contact 521 is connected to the extension plate 522; the extension plate 522 and electrical contact 521 can be integrally formed or separate. In this embodiment, electrical contact 521 is integrally formed on the extension plate 522, and the shape, size, and position of electrical contact 521 on the extension plate 522 are not limited. In this embodiment, electrical contact 521 is located on the +Z axis side of the main body, away from the terminals on the chip 30, reducing the possibility of short circuits. The overall shape of electrical contact 521 can be rectangular.

[0333] In one possible implementation, the electrical contact 521 can be an inclined rectangle, i.e., its long side is at a certain angle to the X-axis direction; or the electrical contact 521 can be an arc shape or other shape that is conducive to the better cooperation and contact of the electrical contact 521 with the probe deformed under the action of the fifth limiting part 642.

[0334] In one possible implementation method, refer to Figure 58 and Figure 59As shown, a latch 525 is provided at the electrical contact 521. A latching protrusion 503c is provided at the mounting position. The material, number, shape, and position of the latch 525 on the electrical contact 521 are not specifically limited, while the number, shape, and position of the latching protrusion 503c correspond to the latch 525. In this embodiment, the latch 525 has two flanges that are arranged opposite to each other. The latching protrusion 503c is a protrusion that protrudes into the mounting position along the -Y axis direction, and its shape is approximately cuboid. The latch 525 and the latching protrusion 503c cooperate to accurately install and fix the electrical contact 521 at the corresponding position on the housing 10, which is beneficial for the electrical contact 521 to make accurate contact with the contact pin 91, and reduces the possibility of the electrical contact 521 moving due to contact with the contact pin 91 during the contact process, ensuring stable contact between the electrical contact 521 and the contact pin 91.

[0335] refer to Figure 58 and Figure 64 As shown, the fifth limiting part 642 guides the contact pin 91 to deform and contact the electrical contact 521 on the extension part 52 during the process of installing the ink cartridge into the mounting part 90. The seventh limiting surface 6421, during the process of installing the ink cartridge into the mounting part 90, is inserted into at least one of the plurality of slits 981-989 of the base 910, thereby guiding the adjacent contact pin 91 of the inserted slit to deform and contact the electrical contact 521 on the extension part 52.

[0336] refer to Figure 60 , Figure 61 and Figure 63 As shown, in this embodiment, during the process of installing the ink cartridge into the mounting portion 90, the fifth limiting part 642 is inserted into the slit adjacent to the slit where the fourth contact pin 914 is located, that is, the slit on the -Y axis side of the fourth contact pin 914. Under the action of the seventh limiting surface 6421, the fourth contact pin 914 deforms and contacts the electrical contact 521 on the extension portion 52. Alternatively, the fifth limiting part 642 may guide the third connecting part 914c of the fourth contact pin 914 to deform and contact the electrical contact 521 on the extension portion 52.

[0337] In one possible implementation, in this embodiment, the fifth limiting part 642 is inserted into the fifth slit 986 during the installation of the ink cartridge into the mounting part 90, causing the third connecting part 914c of the fourth contact pin 914 (specifically, the intersection of the horizontal part 914h and the first vertical part 914k) to shift towards the +Y axis. This ensures that the contact portion of the electrical contact 521 (auxiliary contact terminal) that contacts the fourth contact pin 914 partially overlaps with the contact portion of the third terminal 133. The third connecting part 914c of the fourth contact pin 914 (specifically, the intersection of the horizontal part 914h and the first vertical part 914k) has a notch 984c at the +X and +Z axis positions of the fourth slit 984. The part of the fourth contact pin 914 that contacts the electrical contact 521 (auxiliary contact terminal) is the position where the third connecting part 914c is exposed from the notch 984c.

[0338] In one possible implementation, the shape, number, size, material, and position of the fifth limiting part 642 on the cartridge body are not limited. The fifth limiting part 642 can be located near the -Z axis side of the handle 12 on the cartridge body 10 and adjacent to the extension 52, which facilitates the precise insertion of the fifth limiting part 642 into the corresponding slit and guides the adjacent contact pin 91 of the slit into which it is inserted to deform and contact the electrical contact 521 on the extension 52.

[0339] In this embodiment, the fifth limiting part 642 is disposed near the +Y axis side of the electrical contact 521 on the extension 52. The fifth limiting part 642 is made of rigid material, which is beneficial for guiding the deformation of adjacent styluses.

[0340] The fifth limiting part 642 is a protrusion extending from the housing 10 along the +X axis direction. Preferably, the lower end of the fifth limiting part 642 is narrower, which facilitates its insertion into the slits of the base 910. In this embodiment, the cross-sectional shape of the fifth limiting part 642 is approximately an acute-angled triangle, ensuring that the lower end of the fifth limiting part 642 is narrower, which facilitates its insertion into the slits of the base 910. Of course, the fifth limiting part 642 can also be an equilateral triangle, with the right-angled sides approximately along the Y and Z axes, and the hypotenuse positioned on the side adjacent to the stylus 91 that needs to be deformed, which helps the fifth limiting part 642 accurately guide the adjacent stylus 91 to produce a certain degree of deformation. Furthermore, the acute-angled triangle can divide the -Z axis portion into a tip with a smaller angle, making it easier for the fifth limiting part 642 to insert into the slits of the base 910 while ensuring the degree of deformation guided by the adjacent stylus 91.

[0341] In this embodiment, reference Figure 64 and Figure 65As shown, the installation direction P is along the Z-axis. The ink cartridge is installed into one of the mounting positions of the mounting part 90 along the -Z-axis. During this process, the lower end of the fifth limiting part 642 on the cartridge body 10 is inserted into at least one of the multiple slits of the base 910, thereby guiding the adjacent contact pin of the inserted slit to deform. After the ink cartridge moves a certain distance along the -Z-axis, the handle 12 engages with the internal component of the mounting part 90 to fix the ink cartridge onto the mounting part 90, i.e., the ink cartridge is installed in place. At this time, the terminal 31 on the chip 30 abuts against the contact pin 91 in the mounting part 90 to achieve electrical connection.

[0342] Specifically, the first terminal 131, the second terminal 132, the third terminal 133, and the fifth terminal 135 are electrically connected to the corresponding first connecting portions 911a, 912a, 913a, and 915a of the first contact pin 911, the second contact pin 912, the third contact pin 913, and the fifth contact pin 915, respectively. Simultaneously, the lower end of the fifth limiting portion 642 is inserted into at least one of the multiple slits in the base 910, thereby guiding the adjacent contact pin in the inserted slit to deform and ultimately contact the electrical contact 521 on the extension portion 52.

[0343] Specifically, the fifth limiting part 642 is inserted into the slit on the base 910 adjacent to the slit where the fourth contact pin 914 is located, that is, the slit on the -Y axis side of the fourth contact pin 914, thereby guiding the fourth contact pin 914 to deform and contact the electrical contact 521 on the extension part 52. Specifically, when the ink cartridge is installed to the mounting part 90, one end of the extension part 52 is the electrical contact 521, which makes electrical contact with the fourth contact pin 914, which deforms under the action of the fifth limiting part 642, and receives the electrical signal output by the fourth contact pin 914. The other end of the extension part 52 is the extension plate 522, and the connector 523 of the extension plate 522 is connected to the memory on the ink cartridge chip 30. Specifically, the connector 523 is electrically connected to the memory through the conductive sheet 134A, and transmits the electrical signal received by the electrical contact 521 to the memory to realize the function of resetting the data inside the memory of the chip 30.

[0344] refer to Figure 58 and Figure 59 As shown, two orthogonal straight lines along the surface of the substrate 120 of the chip 30 are defined as the first imaginary line C1 and the second imaginary line C2. The first imaginary line C1 is defined as an extension line along the mounting direction. All contact points C of all terminals 31 of the chip 30 are projected onto the second imaginary line C2 along the mounting direction, and the contact points of the electrical contacts 521 on the extension 52 and the contact pins deformed under the action of the fifth limiting part 642 are also projected onto the second imaginary line C2 along the mounting direction. At this time, the first imaginary line C1 passes through the middle of the two projection positions P that are farthest apart among all the projection positions of the contact points.

[0345] In some embodiments, at least two projection positions overlap. For example, the projection positions P3 and P4 of the third terminal 133 and the fourth terminal 134 overlap, while the projection positions P1, P2, and P5 of the first terminal 131, the second terminal 132, and the fifth terminal 135 do not overlap. In some other embodiments, when a region on one side is designated as the first region Q1 and a region on the other side is designated as the second region Q2 relative to the first imaginary line C1, at least one of the projection positions P1, P2, P3, and P4 partially falls within the second region Q2.

[0346] In this embodiment, a fifth limiting part 642 is provided on the ink cartridge body. During the process of installing the ink cartridge into the mounting part 90, the fifth limiting part 642 is used to guide the contact pin 91 in the mounting part 90 to deform, so that the contact pin 91 on the base 910 contacts the extension part 52. This can limit the ink cartridge from shifting along its own width direction and improve the connection stability between the chip 30 and the contact pin 91.

[0347] In one possible implementation, the chip 30 provided in this embodiment is the same as the above embodiment in terms of structure, terminal arrangement, and function, except for the shape of the substrate 120 and the addition of the contact 60.

[0348] In this embodiment, the main body 51 is approximately square, and the extension 52 is connected to the upper side of the main body 51, i.e., the +Z axis side. The extension 52 is approximately rectangular in shape and is located at the upper left corner of the main body 51, i.e., the -Y axis side of the +Z axis side. The overall shape of the chip 30 is approximately "b" shaped.

[0349] Example 12

[0350] refer to Figure 66 , Figure 67 and Figure 68 As shown, in this embodiment, the guiding component includes a fifth guiding structure 65, and the mounting portion 90 is further provided with a first protrusion 97, which is located on the side of the stylus 91. The fifth guiding structure 65 includes a first pressing member 200 disposed on the housing 10. The first pressing member 200 is configured to abut against the first protrusion 97 and deform. A force-applying portion is disposed on the first pressing member 200. The first pressing member 200 includes a first pressing portion 230, which faces the auxiliary contact terminal.

[0351] In one possible implementation, the first extrusion member 200 includes an extension plate 210, a trigger protrusion 220, and a first extrusion portion 230. One end of the extension plate 210 is connected to the housing 10, and the other end of the extension plate 210 extends to the side of the chip 30 facing away from the housing 10. The first extrusion portion 230 is provided on the side of the extension plate 210 facing the auxiliary contact terminal. The force application portion includes the first extrusion portion 230. The trigger protrusion 220 is provided on the side of the extension plate 210 facing away from the auxiliary contact terminal, and the trigger protrusion 220 abuts against the first protrusion 97.

[0352] refer to Figure 66 , Figure 69 , Figure 71 and Figure 84 As shown, the housing 10 has a chip mounting portion 16 for mounting the chip 30. The direction in which the printing consumable is mounted on the mounting portion 90 is defined as the mounting direction P. In this embodiment, the mounting direction P is the +Z direction. (See reference...) Figure 66 , Figure 67 and Figure 68 As shown, when the printing consumable with chip 30 is installed into the graphics generating device, the first protrusion 97 in the graphics generating device can abut against the first extruder 200. As the printing consumable is installed, the first protrusion 97 deforms the first extruder 200, and one of the multiple contact pins 91 is deformed by the deformed first extruder 200 and accurately abuts against the auxiliary contact terminal on the chip 30, so that the chip 30 is electrically connected to the graphics generating device.

[0353] In this embodiment, the first connecting portion of the stylus 91 may be squeezed and deflected by the deformed first extruder 200, thereby accurately contacting the auxiliary contact terminal on the chip 30.

[0354] In one possible implementation, the extension plate 210, the trigger protrusion 220, and the first extrusion portion 230 are integrally connected as a single structure.

[0355] In one possible implementation, the extension plate 210 may be an elongated strip shape, and the extension plate 210 may be made of a compressible material.

[0356] In one possible implementation, the extension plate 210 is a plate-like structure extending from the side of the chip mounting portion 16 to the +X side of the chip 30, and a trigger protrusion 220 protrudes from the -Y side of the extension plate 210, while a first pressing portion 230 protrudes from the +Y side of the extension plate 210. When the printing consumable with the chip 30 mounted is installed in the graphics generating device, the first pressing member 200 is located between the chip 30 and the stylus 91. The first protrusion 97 located on the side of the stylus 91 can abut against the trigger protrusion 220. As the printing consumable is installed, the first protrusion 97 presses against the trigger protrusion 220, causing the extension plate 210 to deform. The deformation of the extension plate 210 deforms the integral structure of the first pressing portion 230, which can press against the first connecting portion of the stylus 91 that corresponds to the auxiliary contact terminal, thereby connecting the first connecting portion with the auxiliary contact terminal on the chip 30.

[0357] When the printing consumables are accidentally dropped onto the floor with the front surface 120a of the substrate 120 facing down, the first extruder 200 will contact the ground before the chip 30, preventing the chip 30 from being damaged or scratched due to the impact. Furthermore, the first extruder 200 is made of a compressible material, ensuring that it will not be damaged when pressed by the first protrusion 97.

[0358] In this embodiment, reference Figure 70 , Figure 71 , Figure 72 and Figure 73 As shown, the second terminal 132 is an auxiliary contact terminal.

[0359] When the chip 30 is installed in the chip mounting part 16, the first pressing part 230 on the first pressing member 200 is located on the -Y side of the second terminal 132, so that when the printing consumable is installed in the graphic generation device, the first pressing member 200 deforms and abuts against the second contact pin 912, and the second contact pin 912 deforms and abuts against the second terminal 132, thereby realizing the connection between the second contact pin 912 and the chip 30.

[0360] The contact portions of the first terminal 131 and the second terminal 132 overlap in the projection of L2, that is, the first terminal 131 and the second terminal 132 are arranged in the Z direction, and the first contact pin 911 and the second contact pin 912 do not overlap in the Y direction. In order for the first contact pin 911 to abut against the first terminal 131 and the second contact pin 912 to abut against the second terminal 132, a first pressing member 200 is provided to press the second contact pin 912, so that the second contact pin 912 deforms and connects with the second terminal 132, thereby realizing the connection between the contact pin 91 and the chip 30.

[0361] refer to Figure 68 , Figure 72 and Figure 73As shown, the trigger protrusion 220 of the first extruder 200 is provided with a trigger guide surface 221. When the printing consumable is installed in the graphics generating device, the first protrusion 97 on the mounting part 90 abuts against the trigger guide surface 221 on the first extruder 200. As the printing consumable is installed, the first protrusion 97 applies force to the trigger guide surface 221, causing the extension plate 210 to deform. The first extruder 230 moves in the +Y direction to extrude the first connecting part 912a of the second contact pin 912 until the printing consumable is installed in the graphics generating device. The first connecting part 912a is deformed by the first extruder 230 and abuts against the auxiliary contact terminal, so that the chip 30 is electrically connected to the graphics generating device.

[0362] refer to Figure 66 and Figure 68 As shown, in this embodiment, the trigger guide surface 221 is an arc-shaped surface provided on one side of the trigger protrusion in the -Y and -Z directions. When the first protrusion 97 abuts against the trigger guide surface 221, as the printing consumable is continuously installed along the installation direction P, the trigger guide surface 221 can buffer the force applied by the first protrusion 97 to the first pressing member 200, so as to prevent the first protrusion 97 from damaging the trigger protrusion 220 when it abuts against the trigger protrusion 220.

[0363] During the installation of the printing consumable with chip 30 installed into the mounting part 90 of the graphic generation device, the trigger protrusion 220 of the first extrusion member 200 touches the first protrusion 97. The first protrusion 97 applies a force along the +Y direction to the trigger protrusion 220, causing the first extrusion member 200 to deform along the +Y direction. During the deformation, the first extrusion part 230 contacts the first connecting part 912a of the second contact pin 912 and applies a force along the +Y axis to it, causing the first connecting part 912a of the second contact pin 912 to deform along the +Y axis. After the printing consumable is fully installed into the mounting part, the first connecting part 911a of the deformed second contact pin 912 contacts the contact part of the second terminal 132, thereby achieving electrical connection.

[0364] refer to Figure 72 and Figure 73As shown, after the printing consumable is installed into the mounting section 90, the remaining first contact pins 911, third contact pins 913, fourth contact pins 914, and fifth contact pins 915 are directly electrically connected to the first terminal 131, third terminal 133, fourth terminal 134, and fifth terminal 135, respectively, and the first contact pins 911, third contact pins 913, fourth contact pins 914, and fifth contact pins 915 do not deform along the Y-axis. However, to ensure stable contact between the first contact pins 911, third contact pins 913, fourth contact pins 914, and fifth contact pins 915 and the first terminal 131, third terminal 133, fourth terminal 134, and fifth terminal 135, the first contact pins 911 and third contact pins 913 abut against the substrate 120, which can produce movement / deformation along the +X-axis direction.

[0365] refer to Figure 66 and Figure 67 As shown, a snap-fit ​​structure 96 can be provided on the mounting part 90, and a hook 99 can be provided on the handle 12. When the printing consumable is installed in the mounting part 90, the hook 99 engages with the snap-fit ​​structure 96, so that the printing consumable is fixed in the mounting part 90 by the handle 12.

[0366] Example 13

[0367] refer to Figure 66 and Figure 67 As shown, in this embodiment, the mounting part 90 is further provided with a second protrusion 98, and the first protrusion 97 and the second protrusion 98 are located in the -Y direction and the +Y direction of the stylus 91, respectively.

[0368] refer to Figure 66 , Figure 74 , Figure 75 and Figure 77 As shown, the fifth guide structure 65 also includes a second extrusion member 80 disposed on the housing 10. The second extrusion member 80 is configured to abut against the second protrusion 98 and deform thereunder. A force-applying part is disposed on the second extrusion member 80.

[0369] The second extruder 80 includes a movable portion 81, which is slidably connected to the housing 10 and extends to the side of the chip 30 facing away from the housing 10. The second extruder 80 also includes a second extrusion portion 82, which may be the side of the movable portion 81 facing the auxiliary contact terminal. In this example, the force-applying portion includes the second extrusion portion 82, and the side of the movable portion 81 facing away from the auxiliary contact terminal is provided with an abutment portion 811, which abuts against the first protrusion 97.

[0370] When the printing consumables are installed in the graphic generation device, the second extruder 80 can also extrude one of the multiple contact pins 91 to deform the contact pin 91 and make it contact the contact portion of the auxiliary contact terminal, so that the contact pin 91 is accurately connected to the terminal 31 on the chip 30.

[0371] refer to Figure 75 As shown, the printing consumable is also equipped with a first extrusion member 200.

[0372] Compared with Embodiment Twelve, in this embodiment there are two auxiliary contact terminals. The second pressing part 82 is configured to abut against the two contact pins 91 respectively with the first pressing part 230, so that the two contact pins 91 are deformed in opposite and close directions and abut against the two auxiliary contact terminals respectively.

[0373] Reference 75 and Figure 78 As shown, the two auxiliary terminals in this embodiment are the fourth terminal 134 and the fifth terminal 135.

[0374] refer to Figure 66 , Figure 74 , Figure 75 and Figure 77 As shown, the first extrusion member 200 is disposed on the +Y side of the fifth terminal 135, and the trigger protrusion 220 is disposed on the +Y side of the first extrusion portion 230, for reference. Figure 75 , Figure 82 and Figure 83 As shown, when the printing consumable is installed in the graphic generation device, the trigger protrusion 220 of the first extruder 200 abuts against the first protrusion 97, and the first extrusion portion 230 of the first extruder 200 abuts against the fifth contact pin 915 on the +Y side of the fifth terminal 135, applying a force in the -Y direction to the fifth contact pin 915, causing the fifth contact pin 915 to deform in the -Y direction and abut against the fifth terminal 135.

[0375] The second extruder 80 is disposed on the chip mounting part 16 of the printing consumable, just like the first extruder 200. When the printing consumable is installed in the graphic generation device, the second extruder 80 abuts against the second protrusion 98 on the Y side of the stylus 91. The second protrusion 98 applies a force in the +Y direction to the second extruder 80, so that the second extruder 80 can squeeze the stylus.

[0376] refer to Figure 75 , Figure 76 and Figure 79 As shown, the second extruder 80 also includes a guide rail 83, which is disposed on the chip mounting portion 16. A slider 87 is also provided at the bottom of the movable portion 81. The movable portion 81 is mounted on the guide rail 83 via the slider, allowing the movable portion 81 to move on the guide rail 83. (Reference) Figure 66 , Figure 76 and Figure 79 As shown, when the printing consumable is installed in the graphic generation device, the movable part 81 abuts against the second protrusion 98, causing the movable part 81 to move on the guide rail 83, and the movable part 81 can squeeze the stylus 91a.

[0377] In one possible implementation method, refer to Figure 80 , Figure 81 and Figure 82 As shown, the guide rail portion 83 is also provided with an anti-detachment elastic buckle 84, which can prevent the movable portion 81 from detaching. In this embodiment, the anti-detachment elastic buckle 84 is a stop provided on the end of the guide rail portion 83. The stop is provided on the end of the guide rail portion 83 so that the movable portion 81 will not detach from the guide rail portion 83 when it moves.

[0378] In this embodiment, reference Figure 75 , Figure 79 and Figure 80 As shown, the movable part 81 has an approximately n-shaped structure. The slider 87 is disposed on the -X side of the movable part 81. The movable part 81 serves as an abutment part 811 on the -Y side and a second pressing part 82 is disposed on the +Y side. The second pressing part 82 is a protrusion of the movable part 81 on the +Y side. When the chip 30 is mounted on the chip mounting part 16, the movable part 81 is located on the +X side of the chip 30, and the second pressing part 82 is located on the +Y side of the fourth terminal 134 on the chip 30.

[0379] refer to Figure 75 , Figure 79 and Figure 83 As shown, when the printing consumable is installed in the graphic generation device, the second protrusion 98 abuts against the movable part 81. As the printing consumable is installed, the second protrusion 98 drives the movable part 81 to move on the guide rail 83. The movable part 81 can squeeze the fourth contact pin 914, causing the fourth contact pin 914 to deform in the +Y direction. The fourth contact pin 914 abuts against the fourth terminal 134 on the chip 30.

[0380] After the movable part 81 is pressed by the second protrusion 98, it can also be reset on the guide rail 83. That is, when the printing consumable is installed in the graphic generating device, the movable part 81 can be pressed by the second protrusion 98 and abut against the fourth contact pin 914, so that the fourth contact pin 914 abuts against the fourth terminal 134. When the printing consumable is removed from the graphic generating device, the movable part 81 can be reset on the guide rail 83.

[0381] In this embodiment, reference Figure 75 , Figure 79 and Figure 81As shown, the guide rail portion 83 is also provided with an elastic component 85. Preferably, the elastic component 85 is a spring. One end of the guide rail portion 83 is provided with a spring post 86. When the movable part 81 is installed on the guide rail portion 83, one end of the spring is sleeved on the spring post 86, and the other end of the spring abuts against the movable part 81, so that when the movable part 81 moves on the guide rail portion 83, it can be reset on the guide rail portion 83 by the elastic force of the spring. In this embodiment, the anti-disengagement elastic buckle 84 is provided at the -Y end of the guide rail portion 83, the spring post 86 is provided at the +Y end of the guide rail portion 83, the spring is provided on the +Y side of the movable part 81, and the spring post 86 is provided on the -Y side, so that after the movable part 81 is subjected to the force of the first protrusion 97 in the +Y direction and moves in the +Y direction, it can be reset in the -Y direction by the action of the spring.

[0382] refer to Figure 75 , Figure 79 and Figure 81 As shown, the abutting portion 811 of the movable portion 81 is also provided with a fifth guide surface 811a. The fifth guide surface 811a is an arc surface, so that when the first protrusion 97 abuts against the second extruder 80, the second extruder 80 will not be damaged. Furthermore, in this embodiment, the second extruder 80 is made of a material that is not easily deformed, such as plastic.

[0383] Usage process:

[0384] refer to Figure 66 , Figure 75 and Figure 83 As shown, during the process of installing the printing consumable with the chip installed into the mounting part 90 of the graphics generating device, the trigger protrusion 220 of the first extrusion member 200 touches the first protrusion 97, and the first protrusion 97 applies a force along the -Y direction to the trigger protrusion 220, causing the extension plate 210 to deform along the -Y direction. During the deformation, the first extrusion part 230, which is integral with the extension plate 210, deforms in the -Y direction. The first extrusion part 230 contacts the first connecting part 915a of the fifth contact pin 915 and applies a force along the -Y direction to it, causing the first connecting part 915a of the fifth contact pin 915 to deform along the +Y axis. After the printing consumable is fully installed into the mounting part 90, the first connecting part 911a of the deformed fifth contact pin 915 contacts the contact part of the fifth terminal 135, thereby establishing an electrical connection.

[0385] Furthermore, the abutting portion 811 of the second extrusion member 80 contacts the second protrusion 98, and the second protrusion 98 applies a force along the +Y direction to the movable portion 81, causing the movable portion 81 to move along the +Y direction on the guide rail portion 83. During the movement, the second extrusion portion 82 of the movable portion 81 contacts the first connecting portion 914a of the fourth contact pin 914 and applies a force along the +Y axis to it, causing the first connecting portion 914a of the fourth contact pin 914 to deform along the +Y axis. After the printing consumable is fully installed in the mounting portion, the first connecting portion 914a of the deformed fourth contact pin 914 contacts the contact portion C of the fourth terminal 134, thereby achieving electrical connection.

[0386] In some other embodiments, only the second pressing member 80 may be provided on the chip mounting part 16, without the first pressing member 200.

[0387] In this invention, the contact pin and the terminal are connected by compression through the first extrusion member 200 and / or the second extrusion member 80, which allows the spacing between the terminals to be set to be larger, thus separating multiple terminals and preventing foreign objects or friction debris from adhering to the terminals. The terminals can be isolated to avoid short circuits in the chip and improve the safety of chip use.

[0388] Example 14

[0389] The present invention also provides a chip for mounting in the mounting part 90 of a graphics generating device. The chip 30 may be applied to the above-mentioned printing consumables. The printing consumables are used to mount in the mounting part 90 of the graphics generating device. The mounting part 90 is provided with a base 910, and the base 910 is provided with a plurality of contact pins 91. The chip 30 includes a substrate 120 and a plurality of terminals 31 disposed on the substrate 120. The terminals 31 are all used for electrical connection with the contact pins 91.

[0390] At least one of the multiple terminals 31 is an auxiliary contact terminal, and the remaining terminals 31 are direct contact terminals; the contact pin 91 that contacts the auxiliary contact terminal is an auxiliary contact pin, and the remaining contact pins 91 are direct contact pins;

[0391] When the chip 30 is installed in the mounting section 90, the auxiliary contact pin deforms and makes contact with the corresponding auxiliary contact terminal;

[0392] In the installed state, the distance between the contact portion of at least one direct contact terminal and the contact portion of the auxiliary contact terminal is less than the distance between the corresponding direct contact pin and the auxiliary contact pin in the non-installed state.

[0393] refer to Figure 5 and Figure 6 As shown, in this example, the second terminal 132 is an auxiliary contact terminal, the other terminals 31 are direct contact terminals, and the contact pin that contacts the auxiliary contact terminal is an auxiliary contact pin, that is, the second contact pin 912 is an auxiliary contact pin.

[0394] In the installed state, the contact portion of any of the terminals 31 other than the auxiliary contact terminal, such as the contact portion C of the first terminal 131, has a first distance between its contact portion C and the contact portion of the auxiliary contact terminal. In the non-installed state, the distance between the first contact pin 911 and the auxiliary contact pin is a second distance, and the first distance is less than the second distance. That is, the distance in the Y-axis direction between the contact portion C of the second terminal 132 and the contact portion C of the first terminal 131 is less than the distance in the Y-axis direction between the first contact pin 911 and the second contact pin 912 in the non-installed state. This results in a compact terminal arrangement, which is beneficial for miniaturizing the chip 30.

[0395] In one possible implementation, a plurality of terminals 31 are arranged in at least two rows spaced apart from each other along a first direction; the contact portion of at least one auxiliary contact terminal coincides with the projection of the contact portion of at least one of the remaining terminals 31 onto a first plane along a third direction, wherein the first plane is a plane perpendicular to the first direction.

[0396] In one possible implementation, the contact portion of at least one auxiliary contact terminal and the contact portion of at least one direct contact terminal are partially overlapped by the projection of their respective portions onto a first plane in a third direction.

[0397] refer to Figure 6 and Figure 8 As shown, the third-party reference is orthogonal to the first direction, which is the direction indicated by the X-axis, and the first plane is the XY plane. In this example, the terminals are arranged in two rows. The second terminal 132 is an auxiliary contact terminal, and the remaining terminals 31 are direct contact terminals. The second terminal 132 can be located on the inner wall surface of the fourth hole 124. Because the second terminal 132 and the remaining terminals 31 are offset from each other in the third-party direction, at least a portion of the projection of the contact portion C of the second terminal 132 and the contact portion C of the first terminal 131 on the XY plane partially coincides along the third-party direction (i.e., the direction indicated by the X-axis). Alternatively, the contact portion of the second terminal 132 can extend to the front surface 120a of the substrate 120, and at least a portion of the projection of the contact portion C of the second terminal 132 and the contact portion C of the first terminal 131 on the XY plane coincides, making the terminal arrangement compact and facilitating the miniaturization of the chip 30.

[0398] In one possible implementation, there are two auxiliary contact terminals, and along a first direction, the projection portions of the contact portions of the two auxiliary contact terminals on a first plane overlap.

[0399] In one possible implementation, a first guide groove 621 is formed within the chip 30, extending from one edge of the chip 30 to an auxiliary contact terminal. The first guide groove 621 guides the contact pin 91, causing the contact pin 91 to deform and contact the auxiliary contact terminal, thereby achieving a stable electrical connection.

[0400] In one possible implementation, there are two auxiliary contact terminals, and the contact portions of the two auxiliary contact terminals overlap on the projection portion of the first plane; the second guide structure 62 also includes a second guide groove 622 formed in the chip 30, and the first guide groove 621 and the second guide groove 622 extend from the edge of the chip 30 to the two auxiliary contact terminals respectively.

[0401] refer to Figure 35 and Figure 36 As shown, the first guide groove 621 and the second guide groove 622 extend from the edge of the chip 30 to the two auxiliary contact terminals, respectively. Specifically, the first guide groove 621 and the second guide groove 622 extend to the first auxiliary contact terminal (fourth terminal 134) and the second auxiliary contact terminal (ninth terminal 139), respectively. The first guide groove 621 guides the fourth contact pin 914 so that the fourth contact pin 914 stably abuts against the contact portion of the fourth terminal 134. The second guide groove 622 guides the ninth contact pin 919 so that the ninth contact pin 919 stably abuts against the contact portion of the ninth terminal 139.

[0402] In one possible implementation method, refer to Figure 55 and Figure 56 As shown, the chip 30 includes a main body 51 and an extension 52. At least a portion of the multiple terminals 31 are disposed on the main body 51, and auxiliary contact terminals are disposed on the extension 52. The contact pin 91 has a first connecting portion and a third connecting portion. The auxiliary contact terminal contacts the third connecting portion of the corresponding contact pin 91. The direct contact terminal contacts the first connecting portion of the corresponding contact pin 91. The contact portion of the auxiliary contact terminal coincides with the projection portion of the contact portion of at least one direct contact terminal on a first plane.

[0403] The extension 52 can perform the function of at least one of the data terminal, clock terminal, power terminal, reset terminal and ground terminal on the original chip.

[0404] In this embodiment, the extension 52 is electrically connected to the memory of the chip 30 and the fourth contact pin 914 to realize the function of resetting the internal data of the memory of the chip 30.

[0405] In one possible implementation, the extension 52 includes an extension plate 522 and an electrical contact 521 connected to the extension plate 522. The extension plate 522 and the electrical contact 521 can be integrally formed or separately formed. The extension plate 522 is electrically connected to the electrical contact 521 and the memory of the chip 30.

[0406] In this example, the terminals are arranged in three rows, and the electrical contacts 521 on the extension 52 can be auxiliary contacts.

[0407] refer to Figure 60 , Figure 61 and Figure 63As shown, in this embodiment, when the chip 30 provided in this example is installed into the ink cartridge, during the process of installing the ink cartridge into the mounting part 90, the fifth limiting part 642 is inserted into the fifth slit 986, so that the third connecting part 914c of the fourth contact pin 914 (specifically the intersection position of the horizontal part 914h and the first vertical part 914k) is offset towards the +Y axis, thereby ensuring that the contact part of the electrical contact 521 (auxiliary contact terminal) and the fourth contact pin 914 partially overlaps with the contact part of the third terminal 133.

[0408] The third connecting portion 914c of the fourth contact pin 914 (specifically, the intersection of the horizontal portion 914h and the first vertical portion 914k) has a notch 984c at the +X and +Z axis positions of the fourth slit 984. The part of the fourth contact pin 914 that contacts the electrical contact 521 (auxiliary contact terminal) is where the third connecting portion 914c is exposed from the notch 984c. This ensures a stable electrical connection between the chip 30 and the contact pin 91.

[0409] The present invention also provides a printing consumable, including the aforementioned chip, with the chip 30 disposed on the cartridge 10 of the printing consumable.
