DETAILED DESCRIPTION

[0052] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are 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 as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0054] In the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection", "fixation" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0055] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0056] In the above description, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means 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 the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0057] As described in the background technology, during the installation process or the use process after installation, the ink cartridge may be displaced in a direction orthogonal to the installation direction, causing the chip to be displaced 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 found that the reason for this problem is that during the installation process or the use process after installation, the ink cartridge is not constrained in a direction orthogonal to the installation direction, causing the ink cartridge to be displaced in a direction orthogonal to the installation direction, causing the chip to be displaced 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] In order to solve the above problems, an embodiment of the present invention provides an electrical connection component and an ink cartridge, including a receiving member, a chip and two movable members arranged on the receiving member; the chip includes a substrate and two first electrical connection parts. By abutting one side of each movable member in the second direction with the corresponding side block and the other side with the corresponding first contact pin, the two movable members can squeeze the corresponding first contact pin in the second direction, the first contact pin is electrically connected to the corresponding first electrical connection part, and the two first contact pins corresponding to the two movable members are deformed in opposite directions in the second direction, so that the two movable members abut against the corresponding first contact pin and the corresponding side block, the ink cartridge can be constrained in the second direction, and the ink cartridge is suppressed from positional displacement in the second direction during the installation process or the use process after installation, so as to ensure the stability of the contact pin connection between the chip and the device body. In addition, during the installation process of the ink cartridge, the movable member moves in the second direction to achieve the effect with the side block and the first contact pin, and is not easily damaged by the installation part.

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

[0060] refer to Figure 1 and Figure 2 As shown, an ink cartridge 1 provided by the present invention is used to be installed in a mounting portion 90 of an image forming device, wherein 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 a plurality of or one ink cartridge, Figure 1 As shown, the ink cartridge 1 can be detachably installed in the installation direction of the installation portion 90 in the direction indicated by the reference arrow P. After the ink is used up, it is convenient to replace the ink cartridge with a new one by removing the ink cartridge and reinstalling it.

[0061] The image forming device in this embodiment includes but is not limited to a printer, a copier, etc.

[0062] In one possible implementation, reference Figure 3 As shown, the structures of the multiple contact pins 91 are consistent. Each contact pin 91 is a thin sheet of metal that can play a conductive role and is not easy 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. Among them, the first slit 981, the second slit 982, the third slit 983, the fourth slit 984, and the fifth slit 985 correspond to the multiple contact pins 91 one by one, respectively, and the first slit 981, the second slit 982, the third slit 983, the fourth slit 984, and the fifth slit 985 are all U-shaped, and have a slit opening in the +Z axis direction. Each contact pin 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 is connected to the main circuit of the image forming device through the circuit inside the mounting portion 90, and the other side is connected to the chip. The contact pin 91 includes a first connection portion 911a, a second connection portion 911b and a third connection portion 911c, wherein the third connection portion 911c is connected to the first connection portion 911a and the second connection portion 911b. The first connection portion 911a is used to contact the chip; the second connection portion 911b is used to connect to the internal circuit of the image forming device, for example: it is connected to the main circuit in the image forming device through the mounting portion. The contact pin 91 is fixed in a slit through the third connection portion 911c or a part of the third connection portion 911c, and a part of the third connection portion 911c is, for example, a horizontal part 911h of the third connection portion 911c. The first connection portion 911a and the second connection portion 911b are arranged at the end of the contact pin 91, so that the first connection portion 911a and the second connection portion 911b can be elastically deformed and easily restored to their original state after deformation.

[0064] The first connection portion 911a and the second connection portion 911b of the contact pin 91 are respectively arranged on both sides of the base 910. The first connection portion 911a and the second connection portion 911b protrude from the base 910, and the third connection portion 911c does not protrude from the base 910. In a 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 connection part 911c includes a first vertical part 911k and a second vertical part 911j parallel to the direction P, and a horizontal part 911h perpendicular to the direction P, wherein the horizontal part 911h connects the first vertical part 911k and the second vertical part 911j. The first vertical part 911k and the second vertical part 911j extend along the direction P. The end of the first vertical part 911k is connected to the first connection part 911a, and the end of the second vertical part 911j is connected to the second connection part 911b. When the horizontal part 911h or the first vertical part 911k and the second vertical part 911j are fixed to the slit along the +Z axis direction, this structure of the contact pin 91 can make the first connection part 911a and the second connection part 911b of the contact pin 91 elastic, thereby avoiding the contact pin 91 from being worn due to hard contact with the internal circuit and chip 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, and the ink cartridge 1 is detachably mounted on a mounting portion 90 of an image forming device along a first direction (refer to 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 Fig.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, 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, and 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 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 axis coordinate system, is set, in which the X axis, the Y axis, and the Z axis are perpendicular to each other, and 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 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 (Y-axis direction) intersecting the first direction (i.e., the installation direction P, Z-axis direction), that is, in the second direction, there is no other contact pin 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-fitting manner.

[0072] like Figure 7 and Figure 8 As shown, one of the two side blocks 92 is located on the -Y direction side of the ink cartridge 1, and the other side block 92 is located on the +Y direction side of the ink cartridge 1. When the ink cartridge 1 is installed in the installation portion 90 of the image forming device, the two movable components 30 are located between the two side blocks 92, the two first contact pins 91a are located between the two movable components 30, the two movable components 30 are respectively in contact with the two side blocks 92, the two movable components 30 are respectively in contact with the two first contact pins 91a, and the two first contact pins 91a are respectively electrically connected to the corresponding first electrical connection portions 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 installation 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 installation portion 90 along the first direction (that is, the -Z direction). The two movable components 30 are squeezed by the two side blocks 92, and the two movable components 30 move in opposite directions in the second direction. After that, 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, one side of each movable component 30 in the second direction abuts against the corresponding side block 92, and the other side abuts against the corresponding first contact pin 91a, and the two first contact pins 91a corresponding to the two movable components 30 are deformed in opposite directions in the second direction, so that the two movable components 30 abut against the corresponding first contact pins 91a and the corresponding side blocks 92 in the second direction, so that the position displacement of the ink cartridge 1 in the second direction can be suppressed during the installation process of the ink cartridge 1 or the use process after the 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, so as to achieve the effect of the side block 92 and the first contact pin 91a, and the movable member 30 is not easily scratched or worn by the part of the installation portion 90, so that 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 a possible implementation, Fig. 9 As shown, the chip 20 further includes at least two second terminals 23 disposed on the external connection surface 211, and the mounting portion 90 includes a plurality of second contact pins 91b (see Figure 7 As shown in FIG. 1 , each second terminal 23 is electrically connected to a second contact pin 91b; in the second direction, the distance between the contact portions of the two first electrical connection portions 22 and the corresponding first contact pins 91a is smaller than the distance between the contact portions of any two second terminals 23 and the corresponding second contact pins 91b. This arrangement helps to control the deformation amplitude of the two first contact pins 91a within a relatively small range, and also helps to maintain the balanced force of the electrical connection assembly as a whole.

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

[0077] In a possible implementation, Figure 6 and Figure 7 As shown, the movable component 30 includes an elastic arm 31 and a pressing 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 stopper 92, and the pressing arm 32 abuts against the side of the first contact pin 91a.

[0078] The pressing arm 32 is located at 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. Thereafter, 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 component 30 are different, and the rest of the parts are the same.

[0081] In a possible implementation, Fig.10 and Fig.11 As shown, the movable component 30 includes a limiting arm 33 , which is 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 Fig.12 and Fig.13 As shown, when the ink cartridge 1 is installed, the ink cartridge 1 is installed in the installation part 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 installation part 90 along the first direction (that is, the -Z direction), and the two movable components 30 are squeezed by the two side blocks 92. The two movable components 30 move in opposite directions in the second direction, and the elastic arms 31 of the two movable components 30 drive the corresponding limiting arms 33 to move in opposite directions. When the elastic arms 31 of the two movable components 30 abut against the receiving member 10 in the second direction, the squeezing arms 32 corresponding to the elastic arms 31 of the two movable components 30 stop moving in the second direction, and the squeezing arms 32 of the two movable components 30 abut against the corresponding first contact pins 91a, and the first contact pins 91a are electrically connected to the corresponding first electrical connection part 22. By the limiting arms 33 of the two movable components 30 abutting against the receiving member 10 in the second direction, the movable components 30 can be prevented from being excessively squeezed by the side blocks 92, thereby protecting the movable components 30.

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

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

[0086] Among them, Fig. 9 As shown, the first electrical connection portion 22 is a first terminal completely disposed 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. Such a configuration helps to reduce the material usage of the first terminal, thereby reducing costs. It should be noted that both the first terminal and the second terminal 23 are configured using a copper cladding process and are made of metal copper.

[0087] In a possible implementation, Fig.12 and Fig.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, 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, and 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 Fig.11 and Fig.12 As shown, the pressing 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 pressing 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 a possible implementation, Fig.11 As shown, a depression 321 for avoiding 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 connection parts 22 away from the external connection surface 211. In this way, during the installation of the ink cartridge 1, interference between the movable member 30 and the second contact pin 91b can be avoided, 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 a possible implementation, Fig.15 and Fig.19 As shown, the movable member 30 is located on the side of the outer surface 211 facing the receiving member 10, and the first electrical connection portion 22 (see Fig. 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, Fig.16 and Fig.17 As shown, the receiving member 10 has an avoidance hole 101 for the movable member 30 to move in the second direction. When the ink cartridge 1 has not yet been installed on the mounting portion 90, in the second direction, the elastic arm 31 of the movable member 30 can extend out of the receiving member 10 through the avoidance hole 101. It can be understood that when observing along the normal direction of the external surface 211, it can be seen that the movable member 30 extends out of the receiving member 10 in the second direction.

[0096] like Fig.18 As shown, when the ink cartridge 1 is installed in the installation 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 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 conductive member 222 of the corresponding first electrical connection portion 22, and presses the conductive member 222 in the second direction. In this way, the contact stability between the first contact pin 91a and the first electrical connection portion 22 can be improved, and the movable member 30 can be prevented from excessively pressing the first contact pin 91a, thereby protecting the first contact pin 91a.

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

[0098] Among them, Fig. 20 As shown, the conductive member 222 includes a first connecting segment 2221 and a second connecting segment 2222, the first connecting segment 2221 is connected to the second connecting segment 2222, the first connecting segment 2221 is electrically connected to the electrical contact 221, and the second connecting segment 2222 is electrically connected to the first contact pin 91a. It should be noted that, Fig. 20 The dotted line in represents the electrical contact 221.

[0099] In a possible implementation, Fig. 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 penetrates one side of the substrate 21 in the first direction. Specifically, the second hollow portion 214 penetrates the substrate 21 in the -Z direction. When the ink cartridge 1 is installed on the installation portion 90 along the first direction, the first contact pin 91a may enter the second hollow portion 214 along the first direction.

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

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

[0103] like Fig.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 a possible implementation, Fig.21 As shown, the electrical contact 221 is located on the inner surface 212, an electrical contact 221 of the chip 20 has a first projection S1 on the external surface 211, and a second terminal 23 of the chip 20 and a contact portion of the corresponding second contact pin 91b have a second projection S2 on the external surface 211. When observed 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 Fig.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 Fig.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 Fig.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. Fig. 20 As shown, the electrical contact 221 of one of the two first electrical connection parts 22 is located at 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 at the +Y axis side of the second hollow part 214 .

[0106] like Fig. 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. Thereafter, 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 members 222 of the corresponding first electrical connecting portion 22, and squeeze the conductive members 222 in the second direction, and the two conductive members 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.
