[0063] As described in the background technology, the ink cartridge assembly chip in the related art has the problem of poor grounding stability. The inventors have found that the reason for this problem is that the chip used in the ink cartridge is constructed as an external grounding contact, that is, by adding an external conductor or connecting the grounding contact of the chip to a handle made of conductive material, and then directly connecting the external conductor and the handle to the conductive unit in the printing device, so as to achieve the grounding of the chip. Therefore, when the printer is working normally, the external grounding contact of the chip will slide on the surface of the conductive unit along the movement direction of the mounting unit and follow the movement pace of the mounting unit.

[0064] Therefore, during the operation of the printing device, due to environmental factors such as vibration, the external ground contact may fall off the ink cartridge or the contact part may be misplaced, which may cause the external ground contact to lose contact with the surface of the conductive unit, affecting the grounding stability of the chip; in addition, the external ground contact of the chip will generate heat due to long-term friction with the conductive unit, which will cause the external ground contact of the chip to deform, and a stable electrical connection between the two cannot be ensured; further, the external ground contact of the chip will generate large noise during the reciprocating sliding of the external ground contact along the surface of the conductive unit, resulting in a poor user experience.

[0065] In response to the above technical problems, an embodiment of the present application provides an ink cartridge assembly, by setting a connecting assembly between the ground contact of the chip and the conductive unit, wherein the connecting assembly includes a first connecting component and a second connecting component, the first connecting component connects the conductive unit and the second connecting component, and a portion of the first connecting component can be dynamically displaced synchronously with the reciprocating movement posture of the mounting unit, a portion of the first connecting component is connected to the conductive unit, and the second connecting component is connected to the ground contact of the sub-ink cartridge, and has no relative displacement relative to the mounting unit.

[0066] With such a configuration, part of the first connecting component can dynamically displace synchronously with the reciprocating movement of the mounting unit, so that the external contacts of the chip formed by the contact between the first connecting component and the conductive unit have no sliding friction relative to the conductive unit, thereby avoiding the generation of large noise due to the reciprocating sliding of the external contacts along the surface of the conductive unit; and avoiding the deformation of the external contacts due to long-term friction movement with the conductive unit, thereby improving the grounding stability of the chip.

[0067] Furthermore, part of the first connection components is connected to the conductive unit, and part of the first connection components can follow the reciprocating movement of the mounting unit and synchronously and dynamically displace, which can prevent the external contact from being separated from the surface of the conductive unit and improve the grounding stability of the chip.

[0068] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0070] like Figure 1 and Figure 2 As shown, the ink cartridge assembly 100 provided in the embodiment of the present application can be detachably installed in the printing device 200, and the printing device 200 includes an installation unit 210 and a conductive unit 220, wherein the installation unit 210 includes a housing and a stylus assembly 230 disposed in the housing, and the housing is provided with a receiving cavity 215 for inserting the ink cartridge assembly 100, and the stylus assembly 230 is disposed in the receiving cavity 215. A part of the stylus assembly 230 is located in the receiving cavity 215 and is used to be electrically connected to the ink cartridge assembly 100; another part of the stylus assembly 230 is connected to the printing circuit of the printing device 200, and then when the ink cartridge assembly 100 is inserted into the housing, communication can be established with the printing device 200 through the stylus assembly 230.

[0071] The conductive unit 220 in the embodiment of the present application is disposed outside the mounting unit 210, and the conductive unit 220 can be configured to transmit a ground signal. The length extension direction of the conductive unit 220 is consistent with the second direction, and a track (not shown in the figure) is provided at a position adjacent to the conductive unit 220 in the printing device, and the mounting unit 210 can be slidably mounted on the track. When the printing device 200 is working, the mounting unit 210 can slide along the track, and the extension direction of the track is consistent with the extension direction of the conductive unit 220, that is, the mounting unit 210 can slide relative to the conductive unit 220 along the second direction.

[0072] In order to transmit the ground signal in the conductive unit 220 to the ink cartridge assembly 100 , the ink cartridge assembly 100 provided in the embodiment of the present application further includes a connecting component, and the ink cartridge assembly 100 receives the ground signal transmitted by the conductive unit 220 through the connecting component.

[0073] Specifically, the ink cartridge assembly 100 includes at least one sub-ink cartridge 100a, and each sub-ink cartridge 100a can be inserted into the accommodating cavity 215 and electrically connected to the corresponding contact pin assembly 230, and the number of the contact pin assemblies 230 is consistent with the number of the sub-ink cartridges 100a.

[0074] Each sub-ink cartridge 100a includes a cartridge body 10 and a chip 20 disposed on the cartridge body 10, and the chip 20 of each sub-ink cartridge 100a is electrically connected to the corresponding contact pin assembly 230. The chip 20 is provided with one or more contacts, for example, the chip 20 is provided with a plurality of contacts, among which one contact is configured as a ground contact 23, and the ground contact 23 is used to receive a ground signal; the remaining contacts 22 are configured as one or more of storage element contacts, high voltage contacts, and detection contacts (for example, short circuit detection between contacts or installation detection of ink cartridges, etc.), and the remaining contacts are in contact with and electrically connected to the contact pins of the corresponding contact pin assembly 230.

[0075] It should be noted that a storage element 24 is provided on the chip 20 of the sub-ink cartridge, and the storage element contacts and / or detection contacts are electrically connected to the storage unit. The storage element stores communication and data processing programs, ink volume information of the ink cartridge and / or related product information of the ink cartridge, etc., or a high-voltage device is provided on the chip 20 of the sub-ink cartridge, and the high-voltage contacts are electrically connected to the high-voltage device to realize short-circuit detection between contacts, or a detection device is provided on the chip 20 of the sub-ink cartridge, and the detection contacts are electrically connected to the detection device to realize short-circuit detection between contacts or ink cartridge installation detection, etc.

[0076] See also Figure 2 The connection assembly includes a first connection component 30 and a second connection component 40 connected to each other, and the first connection component 30 and the second connection component 40 can both transmit ground signals, wherein the first connection component 30 is used to connect the conductive unit 220 and the second connection component 40, and part of the first connection component 30 is connected to the conductive unit 220 and forms an external contact of the chip. For example, part of the first connection component 30 is fixedly connected to the surface of the conductive unit 220 and has no relative displacement relative to the conductive unit 220.

[0077] Part of the first connecting member 30 is configured to be able to synchronously and dynamically displace following the reciprocating movement of the mounting unit 210 , that is, part of the first connecting member 30 forms an external contact with the conductive unit 220 , and can avoid sliding friction between the external contact and the surface of the conductive unit 220 .

[0078] The second connecting component 40 is disposed on the mounting unit 210 and has no relative displacement relative to the mounting unit 210. For example, the second connecting component 40 is disposed in the accommodating cavity 215 and is fixed relative to the housing. One end of the second connecting component 40 is electrically connected to the ground contact 23 of the chip 20, and the other end is connected to the first connecting component 30, so that the ground signal in the conductive unit 220 can be transmitted to the ground contact 23 of the chip 20 through the first connecting component 30 and the second connecting component 40.

[0079] Compared with the solution in the related art in which the external conductor is directly electrically connected to the conductive unit and the external conductor slides on the surface of the conductive unit along the movement direction of the mounting unit following the movement pace of the mounting unit; in the embodiment of the present application, part of the first connecting component 30 can follow the reciprocating movement of the mounting unit 210 and dynamically displace synchronously, so that the external contact formed by the fixed connection between the other part of the first connecting component 30 and the conductive unit 220 has no sliding friction relative to the conductive unit 220, which can avoid the generation of large noise due to the reciprocating sliding of the external contact along the surface of the conductive unit 220, which affects the user experience.

[0080] Furthermore, part of the first connecting component 30 can follow the reciprocating movement of the mounting unit 210 and dynamically displace synchronously, which can prevent the external contact (the external contact is positioned as the part connecting the first connecting component 30 and the conductive unit 220) from being separated from the surface of the conductive unit 220 due to vibration or the like, and prevent the external contact from being deformed due to long-term sliding friction with the conductive unit 220, thereby improving the grounding stability of the chip 20.

[0081] like Figure 3 As shown, in order to facilitate positioning and supporting the second connecting component 40 when the second connecting component 40 is installed in the accommodating cavity 215, the mounting unit 210 provided in the embodiment of the present application further includes a first supporting portion 211, and along the third direction, the first supporting portion 211 is disposed above the stylus assembly 230. For example, the first supporting portion 211 may be a partial supporting plane formed on the top of the housing, and along the first direction, the supporting plane is located at one side of each stylus assembly 230; along the third direction, the supporting plane is located above each stylus assembly 230.

[0082] In one embodiment, the second connecting component 40 is inserted into the accommodating cavity 215, and part of the second connecting component 40 abuts against the first supporting portion 211, and part of the second connecting component 40 extends along the third direction to the side of the contact pin assembly 230 facing the chip 20, and when the ink cartridge assembly 100 is inserted into the accommodating cavity 215, the part of the second connecting component 40 extending to the contact pin assembly 230 contacts and is electrically connected to the ground contact 23 of the chip 20.

[0083] like Figure 4 and Figure 5As shown, in this embodiment, the second connecting member 40 includes a body 41 and at least one extension portion 42, wherein the body 41 can abut against the first support portion 211, so that the second connecting member 40 is inserted into the housing. The length extension direction of the body 41 is the same as the length extension direction of the first support portion 211, and both extend along the second direction, and the body 41 can fit the support surface of the first support portion 211.

[0084] like Figure 4 , Fig.17 and Fig.18 As shown, the second connecting member 40 includes a plurality of extensions 42, the number of which is consistent with the number of the contact pin assemblies 230 (or the number of the chips 20), that is, each extension 42 corresponds to a chip 20. The plurality of extensions 42 are arranged on the body 41 at intervals along the second direction.

[0085] Each extension portion 42 is tooth-shaped, one end of the extension portion 42 is connected to the main body 41, the other end of the extension portion 42 is constructed to extend along a third direction, and the extension portion 42 can extend to the outside of the contact pin assembly 230; an electrical contact portion 421 is provided on the side of the extension portion 42 facing the chip 20, and the electrical contact portion 421 is used to electrically connect to the ground contact 23 of the chip 20.

[0087] For example, the first positioning portion 411 can be a horizontal plate, one end of which is connected to the main body 41, and the other end of the horizontal plate extends along the first direction toward a side away from the main body 41, that is, the horizontal plate has a horizontal surface that cooperates with the first support portion 211, and when the second connecting component 40 is inserted into the installation unit 210, the above-mentioned first positioning portion 411 can be fitted with the support surface of the first support portion 211, and at least the second connecting component 40 can be limited in the third direction.

[0088] On the basis of the above embodiment, the body 41 is further provided with a second positioning portion 412. The body 41 has an inclined surface, and a plurality of positioning grooves are provided on the inclined surface, and each positioning groove is configured as the second positioning portion 412. The positioning groove extends along the third direction, and its top is provided close to the first positioning portion 411.

[0089] Exemplarily, the positioning groove is configured as a second positioning portion 412, the first positioning portion 411 is located above the top of the positioning groove, and the first positioning portion 411 is located in the extension direction of the positioning groove. The bottom of the positioning groove has an opening, and the opening is located at the bottom of the inclined surface and is arranged near the top of the extension portion 42. For example, the opening of the positioning groove can be arranged between two adjacent extension portions 42.

[0090] See also Figure 3 Accordingly, the mounting unit 210 is provided with a spacer 212 that cooperates with the positioning groove, that is, a plurality of spacers 212 are arranged in the second direction in the accommodating cavity 215, and the spacers 212 extend along the third direction, and an installation space for the stylus assembly 230 is formed between each two adjacent spacers 212. For example, the spacer 212 may be a spacer plate for separating the stylus assemblies 230.

[0091] Along the third direction, at least part of the spacer 212 protrudes from the contact pin assembly 230 and forms a second support portion 212a. The second support portion 212a cooperates with the positioning groove. When the second connecting component 40 is inserted into the accommodating cavity 215, the positioning groove is embedded in the second support portion 212a, that is, the second positioning portion 412 is inserted into the second support portion 212a to limit the second connecting component 40 in at least the first direction and the second direction.

[0092] It should be noted that when the first positioning portion 411 is in contact with the first supporting portion 211, the second positioning portion 412 is inserted into the second supporting portion 212a, that is, the second connecting component 40 can be movably installed in the installation unit 210 under the joint action of the first positioning portion 411 and the second positioning portion 412, and the grounding contact 23 of the chip 20 is electrically connected to the conductive unit 220 through the electrical contact portion 421, the extension portion 42, the main body 41, and the first connecting component 30 to achieve grounding of the chip 20.

[0093] See also Figure 2 In this implementation, the first connecting component 30 provided in the embodiment of the present application includes a conductive carrier, and the conductive carrier extends along a first direction, that is, the length direction of the conductive carrier is consistent with the sliding direction of the mounting unit 210.

[0094] The conductive carrier can be a flexible and deformable conductive metal sheet, which is arranged between the shell and the conductive unit 220, wherein at least a portion of one end of the conductive carrier is fixed on the conductive unit 220, and the other end of the conductive carrier extends to the top of the shell and is electrically connected to the main body 41 of the second connecting component 40 or to the contact portion arranged on the main body 41.

[0095] Furthermore, the length of the conductive carrier has a certain redundancy to form the deformable portion 33. The redundant length is designed to cooperate with the displacement of the mounting unit 210 on the conductive unit 220, so that when the conductive carrier slides on the mounting unit 210, the deformable portion 33 can be telescopically deformed, that is, the deformable portion 33 can follow the reciprocating movement of the mounting unit 210 and dynamically displace synchronously.

[0096] With such a configuration, the external contact formed by the contact between the first connecting member 30 and the conductive unit 220 has no sliding friction with respect to the conductive unit 220, thereby avoiding the generation of large noise due to the reciprocating sliding of the external contact of the chip 20 along the surface of the conductive unit 220; and avoiding the deformation of the external contact of the chip 20 due to long-term friction movement with the conductive unit 220, thereby improving the grounding stability of the chip 20. Furthermore, part of the first connecting member 30 is connected to the conductive unit 220, which can prevent the external contact from being separated from the surface of the conductive unit 220, thereby improving the grounding stability of the chip 20.

[0097] On the basis of the above-mentioned embodiments, the conductive carrier in the embodiments of the present application includes a conductive part and an insulating part, the insulating part wraps part of the conductive part, and the parts of the conductive part exposed from both ends of the insulating part are respectively configured as a first contact part 31 and a second contact part 32; wherein the first contact part 31 is fixedly connected to the conductive unit 220, and the second contact part 32 is electrically connected to the second connecting part 40.

[0098] Exemplarily, the conductive part is configured as a conductive core or a conductive sheet, and the insulating part is configured as an insulating layer that wraps the conductive core. For example, the conductive core includes a first end and a second end that are oppositely disposed, the insulating layer includes a middle portion of the conductive core, and the first end and the second end of the conductive core are exposed from the insulating layer, so that the first end of the conductive core is configured as a first contact portion 31, and the second end of the conductive core is configured as a second contact portion 32, wherein the first contact portion 31 is connected to the side of the conductive unit 220, and the second contact portion 32 is electrically connected to the second connecting component 40.

[0099] It should be noted that, in order to improve the connection reliability between the second contact portion 32 and the second connecting component 40, the second connecting component 40 is provided with a third contact portion 43, and the third contact portion 43 is located on the body 41 of the second connecting component 40 and is arranged close to the second contact portion 32. For example, the third contact portion 43 can be a conductive protrusion (conductive terminal) arranged on the body 41, and the second contact portion 32 can be attached to and electrically connected to the conductive protrusion.

[0100] Furthermore, the entirety or at least a portion of the second connection component 40 is made of a conductive material to ensure that the grounding contact of the chip 20 is electrically connected to the conductive unit 220 through the first connection component 30 and the second connection component 40. For example, in the case of meeting safety requirements, the second connection component 40, except for the third contact portion 43 and the electrical contact portion 421 provided on the extension portion 42, may have the remaining surface of the second connection component 40 coated with an insulating material or provided with an insulating layer to prevent the second connection component 40 from contacting other electrical components and improve the reliability of ground signal transmission.

[0101] The printing device 200 provided in the embodiment of the present application further includes a communication component 240, and at least part of the communication component 240 is deformable. For example, the communication component 240 may be a cable or a track, one end of the communication component 240 is connected to the mounting unit 210, and the other end is connected to the conductive unit 220, and the middle part of the communication component 240 is deformable; an adapter plate is provided in the mounting unit 210, and the adapter plate communicates with the control unit inside the conductive unit 220 through the communication component 240.

[0102] Furthermore, the deformable portion 33 of the first connecting component 30 can be arranged on the body 41 of the communication component 240, that is, the deformable portion 33 of the conductive carrier is attached to the communication component 240. In this way, the first connecting component 30 can be appropriately limited in the printing device 200 to prevent the first connecting component 30 from interfering with or entangled with other internal components, thereby avoiding damage to the first connecting component 30.

[0103] like Figure 6 and Figure 7 As shown, in another implementation of the embodiment of the present application, the first connecting component 30 is disposed on the second connecting component 40 , the first connecting component 30 is configured as a contact member that can move relative to the second connecting component 40 , and the first connecting component 30 can be displaced along the surface of the conductive unit 220 .

[0104] like Figure 8 As shown, the second connecting member 40 in this embodiment includes a third positioning portion 44 and a fourth positioning portion 45, and the third positioning portion 44 and the fourth positioning portion 45 can be an integral structure. The third positioning portion 44 is located above the fourth positioning portion 45, and the third positioning portion 44 extends horizontally along the second direction and the first direction, and the third positioning portion 44 can be arranged parallel to the conductive unit 220. When the second connecting member 40 is installed in the mounting unit 210, the third positioning portion 44 can abut against the top surface of the mounting unit 210.

[0105] See also Figure 3The mounting unit 210 is provided with a third supporting portion 213 cooperating with the third positioning portion 44. The third supporting portion 213 may be a top surface of a portion of the shell. In the embodiment of the present application, the third supporting portion 213 is a portion of the top surface close to the conductive unit 220. Along the first direction, the third supporting portion 213 is located on a side of the first supporting portion 211 away from the ink cartridge assembly 100, and along the third direction, the third supporting portion 213 protrudes from the first supporting portion 211, that is, the height of the third supporting portion 213 is greater than that of the first supporting portion 211.

[0106] The above-mentioned fourth positioning portion 45 is obliquely arranged below the third positioning portion 44, and along the third direction, one side of the fourth positioning portion 45 is connected to the bottom of the third positioning portion 44, and the connected position is located on the side of the third positioning portion 44 facing the cartridge assembly 100, and the other side of the fourth positioning portion 45 extends obliquely downward along the first direction toward one side of the cartridge assembly 100, that is, the fourth positioning portion 45 can be a positioning slope configured on the second connecting component 40.

[0107] Correspondingly, the mounting unit 210 is provided with a fourth supporting portion 214 cooperating with the fourth positioning portion 45. Along the first direction, the fourth supporting portion 214 is located between the first supporting portion 211 and the third supporting portion 213, and the fourth supporting portion 214 can be a supporting inclined surface formed on the top surface of the shell, which cooperates with the above-mentioned positioning inclined surface.

[0108] It should be understood that when the above-mentioned second connecting component 40 is inserted into the accommodating cavity 215 of the shell, the third positioning portion 44 is in affixed with the third supporting portion 213, which can at least limit the second connecting component 40 in the third direction; and the fourth positioning portion 45 is in affixed with the fourth supporting portion 214, which can at least limit the second connecting component 40 in the first direction.

[0109] Furthermore, in this embodiment, the second connecting component 40 also includes a first electrical connecting portion 46 abutting against the first supporting portion 211, wherein the first electrical connecting portion 46 is located on the side of the fourth positioning portion 45 away from the third positioning portion 44; one side of the first electrical connecting portion 46 is connected to the fourth positioning portion 45, and the first electrical connecting portion 46 extends horizontally along the first direction toward one side of the ink cartridge assembly 100.

[0110] For example, the first electrical connection portion 46 can be arranged in parallel with the third positioning portion 44; therefore, along the first direction, the third positioning portion 44 and the first electrical connection portion 46 are respectively arranged in parallel on both sides of the fourth positioning portion 45, and the three form a stepped structure or a Z-shaped structure.

[0111] It should be noted that the entirety or at least a portion of the first electrical connection portion 46 is made of a conductive material, and the first electrical connection portion 46 is used to electrically connect to the ground contact 23 so that the ground signal in the conductive unit 220 is transmitted to the ground contact 23 of the chip 20 via the first connecting component 30, the third positioning portion 44, the fourth positioning portion 45, and the first electrical connection portion 46.

[0112] Based on the above embodiments, the second connecting component 40 in the embodiment of the present application includes a accommodating portion 47, and the accommodating portion 47 is arranged above the third positioning portion 44 along the third direction; an installation shaft 49 is arranged in the accommodating portion 47, the first connecting component 30 is arranged on the installation shaft 49, and the installation shaft 49 is made of conductive material.

[0113] Furthermore, at least a portion of the first connecting component 30 has an electrical contact portion for rolling electrical connection with the conductive unit 220 so that the ground signal in the conductive unit 220 is transmitted to the ground contact 23 of the chip 20 via the first connecting component 30, the mounting axis 49, the third positioning portion 44, the fourth positioning portion 45, and the first electrical connection portion 46.

[0114] Specifically, the accommodation portion 47 is arranged parallel to and above the third positioning portion 44 , and in the first direction, the accommodation portion 47 at least partially overlaps with the projection of the conductive unit 220 to ensure that the first connecting component 30 installed on the accommodation portion 47 can contact the conductive unit 220 .

[0115] The accommodating portion 47 has an accommodating groove, which is in the shape of an elongated strip, and the length extension direction of which is consistent with the extension direction of the conductive unit 220, and the notch of the accommodating groove is arranged toward the conductive unit 220. An installation shaft 49 is arranged in the accommodating groove, and the axial direction of the installation shaft 49 extends along the third direction. The first connecting member 30 is installed on the installation shaft 49 and can rotate relative to the installation shaft 49.

[0116] At least a portion of the first connecting member 30 has an electrical contact portion, and the electrical contact portion is rollingly electrically connected to the conductive unit 220. For example, the first connecting member 30 is configured as a conductive roller, which is rotatably connected to the mounting shaft 49, and the outer circumference of the conductive roller can contact the conductive unit 220, that is, as the mounting unit 210 moves relative to the conductive unit 220, the conductive roller rotates continuously so that the outer circumference at different positions contacts the conductive unit 220.

[0117] With such a configuration, the external contacts formed by the contact between the first connecting component 30 and the conductive unit 220 have no sliding friction relative to the conductive unit 220, thereby avoiding the generation of large noise due to the reciprocating sliding of the external contacts of the chip 20 along the surface of the conductive unit 220; and avoiding the external contacts of the chip 20 from being deformed by heat due to long-term friction movement with the conductive unit 220, thereby improving the grounding stability of the chip 20; and part of the first connecting component 30 is rotatably connected to the conductive unit 220, effectively reducing the situation where the external contacts are separated from the surface of the conductive unit 220 due to wear, thereby improving the grounding stability of the chip 20.

[0118] like Figures 9 to 11 As shown, based on the above embodiment, the connection component in the embodiment of the present application also includes an auxiliary connection component 50, which is used to electrically connect the ground contact 23 and the first electrical connection part 46; such a configuration can improve the applicability and electrical connection reliability of the second connection component 40.

[0119] Specifically, the auxiliary connection component 50 can be configured as a conductive wire or a conductive sheet, and the chip 20 is disposed below the handle 11 of the ink cartridge, and the two maintain a certain distance in the third direction. Further, the chip 20 is also located below the first electrical connection portion 46, and the first electrical connection portion is disposed opposite to the handle 11 and partially overlaps.

[0120] For example, the auxiliary connection component 50 is configured as a conductive sheet, which is arranged between the chip 20 and the first electrical connection portion 46 and is used to electrically connect the ground contact 23 of the chip with the first electrical connection portion 46. The conductive sheet extends along the third direction, a first end of the conductive sheet is connected to the ground contact 23 of the chip 20, a second end of the conductive sheet extends upward along the third direction, the second end of the conductive sheet extends to the handle 11, and is electrically connected to the first electrical connection portion 46.

[0121] The second end of the conductive sheet is provided with a fourth contact portion 51 to form a contact portion thereof; the fourth contact portion 51 may be a conductive terminal provided on the conductive sheet, and the conductive terminal is electrically connected to the first electrical connection portion 46; the fourth contact portion 51 partially overlaps with the handle 11 in the third direction. Exemplarily, a first projection plane formed by a plane where the second direction and the third direction are located is defined, and along the first direction, the projection of the fourth contact portion 51 on the first projection plane partially overlaps with the projection of the handle 11 on the first projection plane.

[0122] like Figures 12 to 16 As shown, the auxiliary connection component 50 is configured as a conductive plate, which can be made integrally with the substrate 21 of the chip 20, that is, the conductive plate is regarded as a part of the substrate 21, that is, along the third direction, a part of the substrate 21 can be extended as the auxiliary connection component 50.

[0123] Along the third direction, the top of the conductive plate is located below the handle 11 and below the first electrical connection portion 46. The ground contact 23 and the fourth contact portion 51 can be disposed at the top of the conductive plate and located on both sides of the conductive plate. The fourth contact portion 51 is located below the handle 11 and is disposed close to the handle 11. The ground contact 23 and the fourth contact portion 51 can be electrically connected through a conductive trace or a via.

[0124] In order to enable the first electrical connection portion 46 to be electrically connected to the ground contact 23 to realize ground signal transmission. In the embodiment of the present application, the second connection component 40 also includes a second electrical connection portion 48, which has a clearance space with the handle 11, and part of the second electrical connection portion 48 is electrically connected to the first electrical connection portion 46, and part of the second electrical connection portion 48 is located below the handle 11 and is electrically connected to the fourth contact portion 51. The fourth contact portion 51 is located below the handle 11, and the two do not overlap; that is, along the first direction, the projection of the fourth contact portion 51 on the first projection plane does not overlap with the projection of the handle 11 on the first projection plane.

[0125] For example, the second electrical connection portion 48 is L-shaped, including a first horizontal segment and a first vertical segment, wherein the first horizontal segment is arranged below the handle 11 and extends along the second direction; the first vertical segment extends along the third direction and is arranged on one side of the handle 11 to avoid the handle 11, and the first vertical segment is connected to the first electrical connection portion 46.

[0126] It should be noted that the entirety or at least a portion of the auxiliary connection component 50 is made of a conductive material to ensure that the ground contact 23 of the chip 20 is electrically connected to the conductive unit 220 through the first connection component 30, the second connection component 40, and the auxiliary connection component 50. For example, in the present embodiment, in the case of ensuring safe use, the other parts of the auxiliary connection component 50 except the fourth contact portion 51 are coated with an insulating material or provided with an insulating layer to prevent the auxiliary connection component 50 from contacting other electrical components and improve the reliability of ground signal transmission.

[0127] The chip 20 provided in the embodiment of the present application includes a substrate 21, a plurality of contacts and a storage element 24 arranged on the substrate 21, wherein the plurality of contacts are electrically connected to the storage element 24. Exemplarily, the plurality of contacts include a ground contact 23, and the ground contact 23 is used to transmit and receive ground signals; the remaining contacts 22 are configured as one or more of storage element contacts, high voltage contacts, and detection contacts (such as short circuit detection between contacts or installation detection of ink cartridges, etc.), and the remaining contacts 22 are in contact with and electrically connected to the contact pins of the corresponding contact pin assembly 230.

[0128] See also Fig.15 and Fig.16As shown, the ground contact 23 can be arranged on the same side as the storage element 24. The ground contact 23 and the storage element are located on the same surface of the substrate 21, and the remaining contacts 22 and the ground contact 23 are located on different surfaces of the substrate 21. The ground contact 23, the remaining contacts 22 and the storage element 24 can be electrically connected through conductive traces.

[0129] like Fig.17 and Fig.18 As shown, the grounding contact 23 and the storage element 24 are located on different sides of the substrate 21, and the grounding contact 23 and the remaining contacts 22 are located on the same side of the substrate 21. When the grounding contact 23 and the remaining contacts 22 are located on the same side of the substrate 21, in this embodiment, a space avoidance portion 25 may be provided between the grounding contact 23 and the remaining contacts 22. With such a configuration, ink or other impurities attached to the chip 20 during use can be stored in the space avoidance portion 25, thereby preventing the impurities from attaching to the two contacts of the chip 20 and causing a short circuit.
