DETAILED DESCRIPTION

[0052] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0053] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of the present invention, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0054] In the present invention, unless otherwise specified or limited, the terms "installed," "connected," "fixed," and the like should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections, electrical connections, or communication between them; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0055] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0056] In the above description, the reference terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" and the like mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples and features of different embodiments or examples described in this specification without mutual contradiction.

[0057] As described in the background art, during the installation process or during use after installation, the ink cartridge may shift in a direction orthogonal to the installation direction. This may cause the chip to shift along with the ink cartridge in a direction orthogonal to the installation direction, affecting the stability of the contact pin connection between the chip and the device body. The inventors have discovered that this problem arises because during the installation process or during use after installation, the ink cartridge is not constrained in a direction orthogonal to the installation direction. This may cause the ink cartridge to shift in a direction orthogonal to the installation direction, causing the chip to shift along with the ink cartridge in a direction intersecting the installation direction, affecting the stability of the contact pin connection between the chip and the device body. It should be noted that the direction orthogonal to the installation direction is the second direction in this application.

[0058] To address the aforementioned issues, an embodiment of the present invention provides an electrical connection assembly and an ink cartridge, comprising a receiving member, a chip disposed on the receiving member, and two movable members; the chip comprises a substrate and two first electrical connection portions. By abutting one side of each movable member in the second direction with a corresponding side block and the other side with a corresponding first contact pin, the two movable members can compress the corresponding first contact pin in the second direction, electrically connecting the first contact pin to the corresponding first electrical connection portion. The two first contact pins corresponding to the two movable members deform in opposite directions in the second direction, thereby constraining the ink cartridge in the second direction by the abutment of the two movable members with the corresponding first contact pins and the corresponding side blocks. During installation or post-installation use of the ink cartridge, the ink cartridge is prevented from shifting in the second direction, thereby ensuring the stability of the contact pin connection between the chip and the device body. Furthermore, during installation of the ink cartridge, the movable member moves in the second direction, interacting with the side block and the first contact pin, making it less susceptible to damage by the installation portion.

[0059] The electrical connection assembly and ink cartridge provided by the embodiments of the present invention are described in detail below with reference to specific embodiments.

[0060] refer to Figure 1 and Figure 2 As shown, the present invention provides an ink cartridge 1, which is used to be installed in a mounting portion 90 of an image forming device. The mounting portion 90 is provided with a base 910, and the base 910 is provided with a plurality of contact pins 91, wherein the mounting portion 90 is a component of the image forming device, and is used to carry multiple or one ink cartridge. Figure 1 As shown, the ink cartridge 1 is detachably mounted to the mounting portion 90 in the direction indicated by the reference arrow P. After the ink is used up, the ink cartridge can be conveniently replaced by removing the ink cartridge and reinstalling a new one.

[0061] The image forming apparatus in this embodiment includes, but is not limited to, a printer, a copier, and the like.

[0062] In one possible implementation, reference Figure 3 As shown, the multiple styluses 91 have the same structure. Each stylus 91 is a thin sheet of metal that provides electrical conductivity and is resistant to wear. The base 910 has a first slit 981, a second slit 982, a third slit 983, a fourth slit 984, and a fifth slit 985. The first slit 981, the second slit 982, the third slit 983, the fourth slit 984, and the fifth slit 985 correspond one-to-one to the multiple styluses 91. Each of the first slit 981, the second slit 982, the third slit 983, the fourth slit 984, and the fifth slit 985 is U-shaped, with a slit opening in the +Z axis direction. Each stylus 91 is installed in one of the slits through a slit opening.

[0063] refer to Figure 3 and Figure 4 As shown, one side of each contact pin 91 connects to the main circuit of the image forming device through the circuitry within the mounting portion 90, and the other side connects to the chip. Contact pin 91 includes a first connecting portion 911a, a second connecting portion 911b, and a third connecting portion 911c. The third connecting portion 911c connects to both the first and second connecting portions 911a and 911b. The first connecting portion 911a is used to contact the chip, while the second connecting portion 911b is used to connect to the internal circuitry of the image forming device, for example, through the mounting portion. Contact pin 91 is secured in a slit by the third connecting portion 911c or a portion thereof, such as the horizontal portion 911h of the third connecting portion 911c. The first and second connecting portions 911a and 911b are positioned at the ends of the contact pin 91, allowing them to elastically deform and easily return to their original shape.

[0064] The first connection portion 911a and the second connection portion 911b of the stylus 91 are respectively provided on either side of the base 910. The first connection portion 911a and the second connection portion 911b protrude from the base 910, while the third connection portion 911c does not protrude from the base 910. In one possible implementation, the first connection portion 911a and the second connection portion 911b protrude from the base 910, and the base 910 is located between the first connection portion 911a and the second connection portion 911b.

[0065] 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. The horizontal portion 911h connects the first and second vertical portions 911k, 911j. The first and second vertical portions 911k, 911j extend along direction P. The distal end of the first vertical portion 911k is connected to the first connecting portion 911a, and the distal end of the second vertical portion 911j is connected to the second connecting portion 911b. When the horizontal portion 911h or the first and second vertical portions 911k, 911j are fixed to the slit along the +Z axis, this structure of the stylus 91 allows the first and second connecting portions 911a, 911b of the stylus 91 to be resilient, preventing wear on the stylus 91 due to hard contact with the internal circuits and chips of the image forming device.

[0066] like Figures 5 to 10 As shown, an embodiment of the present invention provides an electrical connection assembly, which is applied to an ink cartridge 1. The ink cartridge 1 is detachably mounted on a mounting portion 90 of an image forming device along a first direction (refer to FIG. Figure 2As shown in FIG. 1 , the mounting portion 90 includes a plurality of first contact pins 91 a and two side blocks 92 disposed on both sides of the ink cartridge 1 in the second direction.

[0067] The electrical connection assembly includes a receiving member 10, a chip 20 and two movable members 30 arranged on the receiving member 10; the chip 20 includes a substrate 21 and two first electrical connection parts 22, the two first electrical connection parts 22 are arranged on the substrate 21, each first electrical connection part 22 is electrically connected to a first contact pin 91a, and the substrate 21 has an outer surface 211 and an inner surface (not shown in the figure, refer to Figure 14 The inner surface 212 in the figure is understood), the receiving member 10 is connected to the substrate 21; the projections of the contact parts of the two first electrical connecting parts 22 and the corresponding first contact pins 91a in the first direction at least partially overlap; each movable member 30 and each first contact pin 91a can move in the second direction, each movable member 30 corresponds to a first electrical connecting part 22, a side block 92 and a first contact pin 91a, the two movable members 30 are located between the two side blocks 92, and the two first contact pins 91a are located between the two movable members 30, each movable member 30 is constructed to abut against the corresponding side block 92 on one side in the second direction and abut against the corresponding first contact pin 91a on the other side, and each movable member 30 is also constructed to squeeze the corresponding first contact pin 91a in the second direction to electrically connect with the corresponding first electrical connecting part 22.

[0068] The direction in which the ink cartridge 1 is installed on the installation portion 90 is the installation direction of the ink cartridge. The first direction is the installation direction of the ink cartridge. The two directions orthogonal to the first direction are the second direction and the third direction, respectively. The second direction is parallel to the external surface 211 of the substrate 21. It is easy to understand that the second direction and the third direction are both perpendicular to the first direction.

[0069] A three-dimensional rectangular coordinate system, i.e., an XYZ coordinate system, is established, where the X-axis, Y-axis, and Z-axis are perpendicular to each other. The three-dimensional rectangular coordinate system of the ink cartridge 1 is consistent with the three-dimensional rectangular coordinate system of the mounting portion 90. The first direction is the direction in which the Z-axis extends, the second direction is the direction in which the Y-axis extends, and the third direction is the direction in which the X-axis extends.

[0070] like Figure 7 As shown, in this embodiment, the mounting portion 90 includes two first contact pins 91a, and the two first contact pins 91a are all the contact pins 91 of the mounting portion 90 (see Figure 3 When the ink cartridge 1 has not yet been installed in the installation portion 90, the two first contact pins 91a are adjacently arranged in a second direction (the Y-axis direction) that intersects the first direction (i.e., the installation direction P, the Z-axis direction). That is, in the second direction, there are no other contact pins between the two first contact pins 91a.

[0071] The receiving member 10 is fixedly connected to the housing 40 of the ink cartridge 1. The base plate 21 is fixedly connected to the receiving member 10, for example, by a snap-fit ​​method.

[0072] like Figure 7 and Figure 8 As shown, one of the two side stops 92 is located on the -Y side of the ink cartridge 1, and the other side stop 92 is located on the +Y side of the ink cartridge 1. When the ink cartridge 1 is installed in the mounting portion 90 of the image forming apparatus, the two movable members 30 are located between the two side stops 92, and the two first contact pins 91 a are located between the two movable members 30. The two movable members 30 respectively abut the two side stops 92, and the two movable members 30 respectively abut the two first contact pins 91 a. The two first contact pins 91 a are respectively electrically connected to the corresponding first electrical connection portion 22.

[0073] like Figure 7 and Figure 8 As shown, when the ink cartridge 1 is installed, the ink cartridge 1 is installed in the mounting portion 90 of the image forming device along the first direction. The two movable members 30 are inserted between the two side blocks 92 of the mounting portion 90 along the first direction (i.e., the -Z direction). The two movable members 30 are squeezed by the two side blocks 92 and move in opposite directions in the second direction. Thereafter, the two movable members 30 squeeze the corresponding first contact pins 91 a in the second direction, and the first contact pins 91 a are electrically connected to the corresponding first electrical connection portion 22. At this time, one side of each movable member 30 in the second direction abuts the corresponding side block 92 and the other side abuts the corresponding first contact pin 91 a. In addition, the two first contact pins 91 a corresponding to the two movable members 30 are deformed in opposite directions in the second direction. Therefore, the two movable members 30 abut against the corresponding first contact pins 91 a and the corresponding side blocks 92 in the second direction. This can prevent the ink cartridge 1 from shifting in the second direction during installation or use after installation, thereby ensuring the stability of the contact pin connection between the chip 20 and the device body. In addition, during the installation of the ink cartridge 1, the movable member 30 moves in the second direction and gradually changes its shape, which can realize the effect of the side block 92 and the first contact pin 91a. The movable member 30 is not easily scratched or worn by the part of the installation portion 90, and is not easily damaged by the installation portion 90 (see Figure 2 shown) is damaged.

[0074] On the premise that the two first contact pins 91a are arranged adjacent to each other in the second direction, by limiting the projections of the contact parts of the two first electrical connecting parts 22 and the corresponding first contact pins 91a in the first direction to a degree of at least partial overlap, it helps to control the deformation amplitude of the two first contact pins 91a within a relatively small range, and also helps to maintain balanced force on the entire electrical connection assembly.

[0075] In one possible implementation, Figure 9 As shown, the chip 20 further includes at least two second terminals 23 provided on the external surface 211, and the mounting portion 90 includes a plurality of second contact pins 91b (see Figure 7 (As shown), each second terminal 23 is electrically connected to a second contact pin 91b. In the second direction, the spacing between the contact portions of two first electrical connectors 22 and corresponding first contact pins 91a is smaller than the spacing between the contact portions of any two second terminals 23 and corresponding second contact pins 91b. This arrangement helps to control the deformation amplitude of the two first contact pins 91a to a relatively small range and also helps maintain balanced force on the entire electrical connection assembly.

[0076] In this embodiment, the chip 20 includes three second terminals 23, and the mounting portion 90 includes three second contact pins 91b. The three second contact pins 91b are all the contact pins 91 of the mounting portion 90 (see FIG. Figure 3 shown).

[0077] In one possible implementation, Figure 6 and Figure 7 As shown, the movable component 30 includes an elastic arm 31 and a squeezing arm 32 connected to each other. The elastic arm 31 can be deformed in the second direction. The elastic arm 31 is connected to the receiving component 10. The elastic arm 31 abuts against the side block 92, and the squeezing arm 32 abuts against the side of the first contact pin 91a.

[0078] The pressing arm 32 is located on one side of the elastic arm 31 in the second direction.

[0079] When the ink cartridge 1 is installed, the ink cartridge 1 is installed in the mounting portion 90 of the image forming device along the first direction, and the two movable components 30 are inserted between the two side blocks 92 of the mounting portion 90 along the first direction. The elastic arms 31 of the two movable components 30 are squeezed by the two side blocks 92, and the elastic arms 31 of the two movable components 30 are deformed in opposite directions in the second direction. The elastic arms 31 of the two movable components 30 drive the corresponding squeezing arms 32 to move in opposite directions in the second direction. Afterwards, the squeezing arms 32 of the two movable components 30 squeeze the corresponding first contact pins 91a in the second direction, and the first contact pins 91a are electrically connected to the corresponding first electrical connection portion 22. At this time, the elastic arm 31 of each movable component 30 abuts against the corresponding side block 92 in the second direction, and the squeezing arm 32 of each movable component 30 abuts against the corresponding first contact pin 91a.

[0080] The ink cartridge in the second embodiment differs from the ink cartridge in the first embodiment in that the structures of the chip 20 and the movable member 30 are different, while the remaining parts are the same.

[0081] In one possible implementation, Figure 10 and Figure 11 As shown, the movable component 30 includes a limiting arm 33 connected to the elastic arm 31 . The limiting arm 33 can abut against one side of the receiving component 10 in the second direction to limit the movement of the movable component 30 in the second direction.

[0082] The limiting arm 33 is fixedly connected to the elastic arm 31 , and the limiting arm 33 is located on one side of the elastic arm 31 in the third direction.

[0083] like Figure 12 and Figure 13 As shown, when the ink cartridge 1 is installed, it is installed in the mounting portion 90 of the image forming device along a first direction. The two movable members 30 are inserted between the two side blocks 92 of the mounting portion 90 along the first direction (i.e., the -Z direction). The two movable members 30 are squeezed by the two side blocks 92 and move in opposite directions in a second direction. The elastic arms 31 of the two movable members 30 drive the corresponding limiting arms 33 to move in opposite directions. When the elastic arms 31 of the two movable members 30 abut the receiving member 10 in the second direction, the squeezing arms 32 corresponding to the elastic arms 31 of the two movable members 30 stop moving in the second direction. The squeezing arms 32 of the two movable members 30 abut the corresponding first contact pins 91a, which are electrically connected to the corresponding first electrical connection portions 22. The abutment of the limiting arms 33 of the two movable members 30 with the receiving member 10 in the second direction prevents the movable members 30 from being excessively squeezed by the side blocks 92, thereby protecting the movable members 30.

[0084] In one possible implementation, Figure 5 and Figure 10 As shown, the movable component 30 is located on the side of the external surface 211 facing away from the receiving component 10 , and there is a gap between the movable component 30 and the external surface 211 .

[0085] In a possible implementation, the first electrical connection portion 22 is a first terminal at least partially disposed on the external connection surface 211 .

[0086] Among them, Figure 9 As shown, the first electrical connection portion 22 is a first terminal disposed entirely on the external connection surface 211. In the second direction, the width of the first terminal is smaller than the width of the second terminal 23. This arrangement helps reduce the material usage of the first terminal, thereby reducing costs. It should be noted that both the first and second terminals 23 are copper-clad and are made of metallic copper.

[0087] In one possible implementation, Figure 12 and Figure 14As shown, the substrate 21 also includes a first hollow portion 213 that passes through the external surface 211 and the inner surface 212. The first contact pin 91a can be partially located in the first hollow portion 213. The first electrical connection portion 22 is a first terminal having an intersecting first contact surface 2201 and a second contact surface 2202. The first contact surface 2201 is parallel to the external surface 211, and the second contact surface 2202 is parallel to the inner wall of the first hollow portion 213.

[0088] The first hollow portion 213 may be an oblong hole.

[0089] The portion of the first terminal located on the external surface 211 is located on the -Y axis side of the first hollow portion 213, and the portion of the first terminal located inside the first hollow portion 213 is located on the -Y axis side of the inner wall of the first hollow portion 213. The portion of the first terminal located on the external surface 211 is connected to the portion of the first terminal located inside the first hollow portion 213.

[0090] like Figure 11 and Figure 12 As shown, the squeezing arm 32 of the movable component 30 located on the +Y direction side of the first contact pin 91a abuts against the side surface of the corresponding first contact pin 91a, and the side surface of the first contact pin 91a abuts against the portion of the corresponding first terminal located in the first hollow portion 213; the squeezing arm 32 of the movable component 30 located on the -Y direction side of the first contact pin 91a abuts against the side surface of the corresponding first contact pin 91a, and the side surface of the first contact pin 91a abuts against the portion of the corresponding first terminal located at the intersection of the inner wall of the first hollow portion 213 and the external connection surface 211.

[0091] In one possible implementation, Figure 11 As shown, a recessed portion 321 for accommodating the second contact pin 91b is provided on the side of the pressing arm 32 of the movable member 30 corresponding to one of the two first electrical connecting portions 22, facing away from the external connecting surface 211. This arrangement prevents interference between the movable member 30 and the second contact pin 91b during installation of the ink cartridge 1, thereby protecting the second contact pin 91b.

[0092] The recessed portion 321 penetrates the pressing arm 32 in the first direction.

[0093] The pressing arm 32 of the movable member 30 corresponding to the other first electrical connecting portion 22 of the two first electrical connecting portions 22 may not be provided with the recessed portion 321 .

[0094] In one possible implementation, Figure 15 and Figure 19 As shown, the movable member 30 is located on the side of the external surface 211 facing the receiving member 10, and the first electrical connection portion 22 (see Figure 20The conductive member 222 is at least partially located on the inner surface 212, and one side of the conductive member 222 in the second direction abuts against the corresponding first contact pin 91a.

[0095] Among them, such as Figure 16 and Figure 17 As shown, the receiving member 10 has an escape hole 101 for the movable member 30 to move in the second direction. When the ink cartridge 1 has not yet been installed in the mounting portion 90, the elastic arm 31 of the movable member 30 can extend out of the receiving member 10 in the second direction through the escape hole 101. It can be understood that when observing along the normal direction of the external surface 211, the portion of the movable member 30 extending out of the receiving member 10 in the second direction can be seen.

[0096] like Figure 18 As shown, when the ink cartridge 1 is installed in the mounting portion 90, one side of the first contact pin 91a abuts the conductive member 222 in the second direction, and the other side of the first contact pin 91a abuts the movable member 30. When the pressing arm 32 of the movable member 30 presses the corresponding first contact pin 91a in the second direction, the first contact pin 91a is electrically connected to the corresponding conductive member 222 of the first electrical connection portion 22 and presses the conductive member 222 in the second direction. This arrangement improves the contact stability between the first contact pin 91a and the first electrical connection portion 22 and prevents the movable member 30 from excessively pressing the first contact pin 91a, thereby protecting the first contact pin 91a.

[0097] In a possible implementation, the conductive member 222 is an elastic component that can be deformed in the second direction.

[0098] Among them, such as Figure 20 As shown, the conductive member 222 includes a first connecting section 2221 and a second connecting section 2222. The first connecting section 2221 is connected to the second connecting section 2222. The first connecting section 2221 is electrically connected to the electrical contact 221, and the second connecting section 2222 is electrically connected to the first contact pin 91a. Figure 20 The dotted line in represents the electrical contact 221 .

[0099] In one possible implementation, Figure 20 As shown, the substrate 21 also includes a second hollow portion 214 that passes through the external surface 211 and the inner surface 212. The first contact pin 91a can be partially located in the second hollow portion 214. When observed along the normal direction of the external surface 211, the projection of the conductive member 222 and the projection of the movable component 30 can both be at least partially located within the extension range of the second hollow portion 214.

[0100] The second hollow portion 214 may be a U-shaped hole. The second hollow portion 214 extends through one side of the substrate 21 in the first direction. Specifically, the second hollow portion 214 extends through the substrate 21 in the -Z direction. When the ink cartridge 1 is installed in the mounting portion 90 along the first direction, the first contact pin 91 a can enter the second hollow portion 214 along the first direction.

[0101] The first connecting segment 2221 of the conductive member 222 is located on the inner surface 212 . The projection of the second connecting segment 2222 is located within the extension range of the second hollow portion 214 perpendicular to the outer surface 211 .

[0102] The first connecting section 2221 may be in a rectangular shape, and the second connecting section 2222 may be in a U-shape.

[0103] like Figure 18 As shown, when the ink cartridge 1 is installed in the mounting portion 90, in the second direction, one side of the first contact pin 91a abuts against the conductive member 222, and the other side of the first contact pin 91a abuts against the movable component 30. At this time, when observed along the normal direction of the external surface 211, the projection of the second connecting section 2222 of the conductive member 222 and the projection of the squeezing arm 32 of the movable component 30 are at least partially located within the extension range of the second hollow portion 214.

[0104] In one possible implementation, Figure 21 As shown, the electrical contact 221 is located on the inner surface 212. One electrical contact 221 of the chip 20 has a first projection S1 on the external surface 211. The contact portion between one second terminal 23 of the chip 20 and the corresponding second contact pin 91b has a second projection S2 on the external surface 211. When viewed along the normal direction of the external surface 211, the projections of the first projection S1 and the second projection S2 in the second direction at least partially overlap. It should be noted that Figure 21 The straight line S in the figure extends along the second direction, and the projection of the first projection S1 in the second direction can be understood as Figure 21 The straight line segment corresponding to S11 in the figure, the projection of the second projection S2 in the second direction can be understood as Figure 21 The straight line segment corresponding to S21 in .

[0105] The electrical contact 221 protrudes from the inner surface 212 in a direction perpendicular to the outer surface 211. Figure 20 As shown, the electrical contact 221 of one of the two first electrical connection parts 22 is located on the −Y axis side of the second hollow part 214 , and the electrical contact 221 of the other first electrical connection part 22 is located on the +Y axis side of the second hollow part 214 .

[0106] like Figure 20As shown, the outer surface 211 and the inner surface 212 are parallel to each other, and both the outer surface 211 and the inner surface 212 can be planes.

[0107] When the ink cartridge 1 is installed, the ink cartridge 1 is installed in the mounting portion 90 of the image forming device along the first direction, and the two movable components 30 are inserted between the two side blocks 92 on the mounting portion 90 located on both sides of the ink cartridge 1 in the second direction along the first direction. The elastic arms 31 of the two movable components 30 are squeezed by the two side blocks 92, and the elastic arms 31 of the two movable components 30 are deformed in opposite directions in the second direction. The elastic arms 31 of the two movable components 30 drive the corresponding squeezing arms 32 to move in opposite directions in the second direction. Afterwards, the squeezing arms 32 of the two movable components 30 squeeze the corresponding first contact pins 91a in the second direction, and the two first contact pins 91a are deformed in opposite directions in the second direction. The two first contact pins 91a are electrically connected to the conductive parts 222 of the corresponding first electrical connecting parts 22, and squeeze the conductive parts 222 in the second direction. The two conductive parts 222 are deformed in opposite directions in the second direction, which can suppress the position displacement of the ink cartridge 1 in the second direction and ensure the stability of the contact pin connection between the chip 20 and the device body.
