[0063] As described in the background, the cartridge assembly chip in the related art has poor grounding stability. The inventor has found that the cause of this problem is that the chip used by the cartridge is configured as an external grounding contact, that is, an external conductor is added or the grounding contact of the chip is connected with a handle made of conductive material, and the external conductor is directly connected with the conductive unit in the printing device to realize 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 motion direction of the installation unit.

[0064] Therefore, during the working process of the printing device, the external grounding contact of the chip may be detached from the cartridge or the contact part may be misaligned due to environmental factors such as vibration, thereby causing the problem that the external grounding contact of the chip is separated from the surface of the conductive unit, affecting the grounding stability of the chip. In addition, the external grounding contact of the chip may generate heat due to long-time friction with the conductive unit, thereby causing the deformation of the external grounding contact of the chip, and the stable electrical connection between the two cannot be ensured. Furthermore, the external grounding contact of the chip may generate a large noise during the reciprocating sliding process along the surface of the conductive unit, and the user experience is poor.

[0065] To solve the above technical problems, the present application provides a cartridge assembly. A connecting assembly is arranged between the grounding 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 is connected with the conductive unit and the second connecting component, and part of the first connecting component can be dynamically displaced synchronously with the reciprocating movement of the installation unit. Part of the first connecting component is connected with the conductive unit, and the second connecting component is connected with the grounding contact of the sub-cartridge and has no relative displacement with respect to the installation unit.

[0066] In this way, part of the first connecting component can be dynamically displaced synchronously with the reciprocating movement of the installation unit, thereby avoiding the sliding friction of the external contact of the chip with respect to the conductive unit, avoiding the generation of a large noise during the reciprocating sliding process of the external contact along the surface of the conductive unit, and avoiding the deformation of the external contact due to long-time friction with the conductive unit, thereby improving the grounding stability of the chip.

[0067] Furthermore, part of the first connecting component is connected with the conductive unit, and part of the first connecting component can be dynamically displaced synchronously with the reciprocating movement of the installation unit, thereby avoiding the separation of the external contact from the surface of the conductive unit and improving 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 easy to understand, 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 making creative work are within the scope of protection of this application.

[0069] To facilitate the description of the embodiments of the present application, the coordinate system in the accompanying drawings is first explained, wherein the X-axis is the first direction, the Y-axis is the second direction, and the second direction is defined as the reciprocating sliding direction of the mounting unit; the Z-axis is the third direction, and the third direction is defined as the direction of insertion of the ink cartridge assembly into the mounting unit, and the first direction is defined as the normal to the plane formed by the second direction and the third direction.

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

[0071] In the embodiment of the present application, the conductive unit 220 is disposed outside the mounting unit 210. The conductive unit 220 can be configured to transmit a ground signal. The conductive unit 220 extends in a direction that aligns with the second direction. A track (not shown) is provided adjacent to the conductive unit 220 in the printing device. The mounting unit 210 is slidably mounted on the track. When the printing device 200 is in operation, the mounting unit 210 can slide along the track, and the track extends in a direction that aligns with the direction of extension of the conductive unit 220. In other words, the mounting unit 210 can slide relative to the conductive unit 220 in 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 comprises at least one sub-ink cartridge 100a, and each sub-ink cartridge 100a is capable of being inserted into the accommodating cavity 215 and electrically connected with the corresponding stylus assembly 230, and the number of the stylus assemblies 230 is consistent with the number of the sub-ink cartridges 100a.

[0074] Each sub-ink cartridge 100a comprises a cartridge body 10 and a chip 20 arranged on the cartridge body 10, and the chip 20 of each sub-ink cartridge 100a is electrically connected with the corresponding stylus 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 for receiving a ground signal, and the remaining contacts 22 are configured as one or more of a storage element contact, a high-voltage contact, and a detection contact (such as short-circuit detection between contacts or installation detection of the ink cartridge, etc.), and the remaining contacts are in contact with and electrically connected with the respective stylus of the corresponding stylus assembly 230.

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

[0076] Referring to Figure 2 , the connecting assembly comprises a first connecting component 30 and a second connecting component 40 connected with each other, and the first connecting component 30 and the second connecting component 40 are both capable of transmitting a ground signal, wherein the first connecting component 30 is used to connect the conductive unit 220 with the second connecting component 40, and part of the first connecting component 30 is connected with the conductive unit 220 and forms an external contact of the chip. For example, part of the first connecting component 30 is fixedly connected with the surface of the conductive unit 220 and has no relative displacement with respect to the conductive unit 220.

[0077] Part of the first connecting component 30 is configured to be capable of following the reciprocating movement posture of the mounting unit 210 and synchronously dynamically displacing, that is, part of the first connecting component 30 forms an external contact with the conductive unit 220, and is capable of avoiding sliding friction between the external contact and the surface of the conductive unit 220.

[0078] The second connecting component 40 is arranged on the mounting unit 210 and has no relative displacement with respect to the mounting unit 210. For example, the second connecting component 40 is arranged in the accommodating cavity 215 and is fixed with respect to the shell. One end of the second connecting component 40 is electrically connected with the ground contact 23 of the chip 20, and the other end is connected with 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 scheme in the related art in which the external conductive body is directly electrically connected with the conductive unit, and the external conductive body slides on the surface of the conductive unit along the movement direction of the mounting unit in the movement rhythm of the mounting unit, in the embodiment of the present application, part of the first connecting component 30 can synchronously and dynamically displace along with the reciprocating movement of the mounting unit 210, so that the other part of the first connecting component 30 is fixedly connected with the external contact formed by the conductive unit 220, and the external contact has no sliding friction with respect to the conductive unit 220, which can avoid generating large noise in the process of reciprocating sliding of the external contact along the surface of the conductive unit 220, and affect the user experience.

[0080] Further, part of the first connecting component 30 can synchronously and dynamically displace along with the reciprocating movement of the mounting unit 210, which can avoid the external contact (the external contact is positioned at the part of the first connecting component 30 connected with the conductive unit 220) from being separated from the surface of the conductive unit 220 due to vibration and other reasons, and avoid the deformation of the external contact due to long-time sliding friction with the conductive unit 220, thereby improving the grounding stability of the chip 20.

[0081] As shown in Figure 3 In order to facilitate positioning and supporting the second connecting component 40 when the second connecting component 40 is mounted in the accommodating cavity 215, the mounting unit 210 provided in the embodiment of the present application further includes a first supporting part 211 arranged above the contact pin assembly 230 along the third direction. For example, the first supporting part 211 can be a part of the supporting plane formed on the top of the shell, and along the first direction, the supporting plane is located on one side of each contact pin assembly 230; along the third direction, the supporting plane is located above each contact pin 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 part 211, and part of the second connecting component 40 extends to one side of the contact pin assembly 230 facing the chip 20 along the third direction, 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 is in contact with and electrically connected with the ground contact 23 of the chip 20.

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

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

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

[0086] Further, the body 41 is provided with a first positioning part 411. In the first direction, the extensions 42 are arranged on the body 41 in a spaced manner with the first positioning part 411. In the third direction, the first positioning part 411 can be arranged at the top of the second connecting component 40.

[0087] For example, the first positioning part 411 can be a horizontal plate, one end of the horizontal plate is connected to the body 41, the other end of the horizontal plate extends along the first direction to the side away from the body 41, i.e., the horizontal plate has a horizontal surface matched with the first support part 211, and when the second connecting component 40 is inserted into the mounting unit 210, the above-mentioned first positioning part 411 can be attached to the support surface of the first support part 211, and at least can limit the second connecting component 40 in the third direction.

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

[0089] Exemplarily, the positioning groove is configured as the 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 close to 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] Referring to Figure 3 Correspondingly, the mounting unit 210 is provided with a plurality of spacers 212 matched with the positioning groove, i.e., a plurality of spacers 212 are arranged in the second direction in the accommodation cavity 215, the spacers 212 extend in the third direction, and each adjacent two spacers 212 form an installation space of the contact pin assembly 230. For example, the spacer 212 can be a spacer plate for separating the contact pin assemblies 230.

[0091] In the third direction, at least part of the spacer 212 protrudes from the contact pin assembly 230 and forms a second supporting portion 212a, and the second supporting portion 212a is matched with the positioning groove. When the second connecting component 40 is inserted into the accommodation cavity 215, the positioning groove is embedded on the second supporting portion 212a, i.e., the second positioning portion 412 is inserted into the second supporting portion 212a to limit the second connecting component 40 at least in the first direction and the second direction.

[0092] It should be noted that when the first positioning portion 411 is attached to the first supporting portion 211, the second positioning portion 412 is inserted into the second supporting portion 212a at this time, i.e., the second connecting component 40 is inserted into the mounting unit 210 under the joint action of the first positioning portion 411 and the second positioning portion 412, and the ground 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 body 41, and the first connecting component 30, so as to realize the grounding of the chip 20.

[0093] Referring to Figure 2 In this embodiment, the first connecting component 30 provided by the application includes a conductive carrier which extends in the first direction, i.e., 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 conductive metal sheet with flexibility and deformability, and the conductive carrier is arranged between the shell and the conductive unit 220, wherein at least part of one end of the conductive carrier is fixed on the conductive unit 220, and the other end of the conductive carrier extends above the shell and is electrically connected with the body 41 of the second connecting component 40 or with the contact portion arranged on the body 41.

[0095] Further, the length of the conductive carrier has a certain redundancy to form the deformable part 33. The redundant length is designed to cooperate with the displacement of the mounting unit 210 on the conductive unit 220, so that the deformable part 33 can be deformed in extension or contraction when the mounting unit 210 slides, that is, the deformable part 33 can be synchronously displaced dynamically following the reciprocating posture of the mounting unit 210.

[0096] In this way, the outer contact formed by the contact of the first connecting part 30 and the conductive unit 220 has no sliding friction with the conductive unit 220, avoiding the generation of relatively large noise in the process of reciprocating sliding of the outer contact of the chip 20 along the surface of the conductive unit 220, and avoiding the deformation of the outer contact of the chip 20 due to long-time friction with the conductive unit 220, thereby improving the grounding stability of the chip 20. Further, the connection of part of the first connecting part 30 with the conductive unit 220 can avoid the disconnection of the outer contact with 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 comprises a conductive part and an insulating part, the insulating part wraps part of the conductive part, and the part of the conductive part exposed from both ends of the insulating part is respectively configured as a first contact part 31 and a second contact part 32; wherein the first contact part 31 is fixedly connected with the conductive unit 220, and the second contact part 32 is electrically connected with the second connecting part 40.

[0098] Illustratively, the conductive part is configured as a conductive core or a conductive sheet, and the insulating part is configured as an insulating layer wrapping the conductive core. For example, the conductive core comprises oppositely arranged first and second ends, the insulating layer comprises the middle part of the conductive core, and the first and second ends of the conductive core are exposed from the insulating layer, so that the first end of the conductive core is configured as the first contact part 31, and the second end of the conductive core is configured as the second contact part 32, wherein the first contact part 31 is connected with the side surface of the conductive unit 220, and the second contact part 32 is electrically connected with the second connecting part 40.

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

[0100] And, the entirety or at least a part of the second connecting component 40 is made of conductive material to meet the electric connection of the ground contact of the chip 20 through the first connecting component 30, the second connecting component 40 and the conductive unit 220. For example, in the case of meeting the safe use, the rest surface of the second connecting component 40 except the electric contact 421 on the third contact 43 and the extension 42 can be coated with insulating material or provided with insulating layer to avoid the contact of the second connecting component 40 with other electric elements and improve the reliability of the ground signal transmission.

[0101] The printing device 200 provided by the embodiment of the present application further comprises a communication component 240, and at least part of the communication component 240 is deformable. For example, the communication component 240 can be a flat cable or a track, one end of the communication component 240 is connected with the mounting unit 210, the other end is connected with the conductive unit 220, and the intermediate part of the communication component 240 is deformable; the mounting unit 210 is provided with a relay board, and the relay board communicates with the control unit inside the conductive unit 220 through the communication component 240.

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

[0103] As shown in Figure 6 and Figure 7 In another embodiment of the present application, the first connecting component 30 is arranged on the second connecting component 40, the first connecting component 30 is configured as a contact piece movable 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] As shown in Figure 8 The second connecting component 40 in this embodiment comprises a third positioning part 44 and a fourth positioning part 45, and the third positioning part 44 and the fourth positioning part 45 can be an integral structure. The third positioning part 44 is located above the fourth positioning part 45, and the third positioning part 44 extends horizontally along the second direction and the first direction, and the third positioning part 44 can be arranged in parallel with the conductive unit 220. When the second connecting component 40 is mounted into the mounting unit 210, the third positioning part 44 can abut against the top surface of the mounting unit 210.

[0105] Referring to Figure 3The mounting unit 210 is provided with a third supporting part 213 matched with the third positioning part 44. The third supporting part 213 can be a top surface of the partial housing. In the embodiment, the third supporting part 213 is a partial top surface close to the conductive unit 220. In the first direction, the third supporting part 213 is located on the side of the first supporting part 211 away from the ink cartridge assembly 100. In the third direction, the third supporting part 213 protrudes from the first supporting part 211, i.e., the height of the third supporting part 213 is greater than that of the first supporting part 211.

[0106] The fourth positioning part 45 is obliquely arranged below the third positioning part 44. In the third direction, one side of the fourth positioning part 45 is connected with the bottom of the third positioning part 44. The connected position is on the side of the third positioning part 44 facing the ink cartridge assembly 100. The other side of the fourth positioning part 45 obliquely extends downward in the first direction toward the side of the ink cartridge assembly 100, i.e., the fourth positioning part 45 can be a positioning inclined surface arranged on the second connecting part 40.

[0107] Correspondingly, the mounting unit 210 is provided with a fourth supporting part 214 matched with the fourth positioning part 45. In the first direction, the fourth supporting part 214 is located between the first supporting part 211 and the third supporting part 213. The fourth supporting part 214 can be a supporting inclined surface formed on the top surface of the housing, which is matched with the above-mentioned positioning inclined surface.

[0108] It should be understood that when the second connecting part 40 is inserted into the accommodating cavity 215 of the housing, the third positioning part 44 is attached to the third supporting part 213, which can at least limit the second connecting part 40 in the third direction. The fourth positioning part 45 is attached to the fourth supporting part 214, which can at least limit the second connecting part 40 in the first direction.

[0109] Further, in the embodiment, the second connecting part 40 further includes a first electrical connecting part 46 abutting against the first supporting part 211. The first electrical connecting part 46 is located on the side of the fourth positioning part 45 away from the third positioning part 44. One side of the first electrical connecting part 46 is connected with the fourth positioning part 45, and the other side of the first electrical connecting part 46 extends horizontally in the first direction toward the side of the ink cartridge assembly 100.

[0110] For example, the first electrical connecting part 46 can be arranged parallel to the third positioning part 44. Therefore, in the first direction, the third positioning part 44 and the first electrical connecting part 46 are respectively arranged parallel to the two sides of the fourth positioning part 45, and the three parts form a stepped structure or a Z-shaped structure.

[0111] It should be noted that the first electric connection part 46 is made of electrically conductive material as a whole or at least in part, and is used to electrically connect with 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 through the first connecting part 30, the third positioning part 44, the fourth positioning part 45 and the first electric connection part 46.

[0112] On the basis of the above-mentioned embodiments, the second connecting part 40 in the embodiments of the present application comprises a receiving part 47, and the receiving part 47 is arranged above the third positioning part 44 along the third direction; a mounting shaft 49 is arranged in the receiving part 47, and the first connecting part 30 is arranged on the mounting shaft 49, and the mounting shaft 49 is made of electrically conductive material.

[0113] Further, at least a part of the first connecting part 30 has an electric contact part, which is used to electrically connect with the conductive unit 220 in rolling, so that the ground signal in the conductive unit 220 is transmitted to the ground contact 23 of the chip 20 through the first connecting part 30, the mounting shaft 49, the third positioning part 44, the fourth positioning part 45 and the first electric connection part 46.

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

[0115] The receiving part 47 has a receiving groove, which is in the shape of a long strip, and the length extension direction of the receiving groove is consistent with the extension direction of the conductive unit 220, and the groove opening of the receiving groove is arranged towards the conductive unit 220. The mounting shaft 49 is arranged in the receiving groove, the axial direction of the mounting shaft 49 extends along the third direction, the first connecting part 30 is mounted on the mounting shaft 49, and can rotate relative to the mounting shaft 49.

[0116] At least a part of the first connecting part 30 has an electric contact part, and the electric contact part is electrically connected with the conductive unit 220 in rolling. For example, the first connecting part 30 is configured as an electrically conductive roller, which is rotatably connected to the mounting shaft 49, and the outer peripheral surface of the electrically conductive roller can contact the conductive unit 220, that is, as the mounting unit 210 moves relative to the conductive unit 220, the electrically conductive roller continuously rotates, so that the outer peripheral surface at different positions contacts the conductive unit 220.

[0117] In this way, the first connecting component 30 and the outer contact formed by the contact between the first connecting component 30 and the conductive unit 220 have no sliding friction with the conductive unit 220, which avoids the generation of a large noise in the process of the outer contact of the chip 20 reciprocating along the surface of the conductive unit 220, and avoids the phenomenon that the outer contact of the chip 20 is deformed due to long-time friction with the conductive unit 220, thereby improving the grounding stability of the chip 20; and part of the first connecting component 30 is rotationally connected with the conductive unit 220, which effectively reduces the situation that the outer contact is separated from the surface of the conductive unit 220 due to wear, thereby improving the grounding stability of the chip 20.

[0118] As shown in Figure 9 to Figure 11 Based on the above embodiment, the connecting assembly in the embodiment of the present application further includes an auxiliary connecting component 50, which is used to electrically connect with the ground contact 23 and the first electrical connecting part 46; in this way, the applicability and electrical connection reliability of the second connecting component 40 can be improved.

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

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

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

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

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

[0124] In order to enable the first electrical connection part 46 to be electrically connected with the ground contact 23 to realize ground signal transmission. In the embodiment of the application, the second connecting part 40 further comprises a second electrical connection part 48, the second electrical connection part 48 has a space away from the handle 11, and part of the second electrical connection part 48 is electrically connected with the first electrical connection part 46, and part of the second electrical connection part 48 is below the handle 11 and electrically connected with the fourth contact part 51. The fourth contact part 51 is below the handle 11 and does not coincide with the handle 11; that is, in the first direction, the projection of the fourth contact part 51 on the first projection plane does not coincide with the projection of the handle 11 on the first projection plane.

[0125] For example, the second electrical connection part 48 is L-shaped and includes a first horizontal segment and a first vertical segment, wherein the first horizontal segment is arranged below the handle 11 and extends in the second direction; the first vertical segment extends in 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 with the first electrical connection part 46.

[0126] It should be noted that the whole or at least part of the auxiliary connecting part 50 is made of a conductive material to enable the ground contact 23 of the chip 20 to be electrically connected with the conductive unit 220 through the first connecting part 30, the second connecting part 40 and the auxiliary connecting part 50. For example, in the case of meeting the safety use, other parts of the auxiliary connecting part 50 except the fourth contact part 51 are coated with an insulating material or provided with an insulating layer in the embodiment to avoid the auxiliary connecting part 50 from contacting other electrical elements and to improve the reliability of ground signal transmission.

[0127] The chip 20 provided by the embodiment of the application comprises a substrate 21 and a plurality of contacts and a storage element 24 arranged on the substrate 21, wherein the plurality of contacts are electrically connected with the storage element 24. For example, the plurality of contacts include a ground contact 23 for transmitting and receiving a ground signal; and the remaining contacts 22 are configured as one or more of a storage element contact, a high-voltage contact and a detection contact (such as short-circuit detection between contacts or installation detection of an ink cartridge).

[0128] Referring to Figure 15 and Figure 16As shown, the ground contact 23 can be disposed 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 by conductive traces.

[0129] As shown, the ground contact 23 and the storage element 24 are located on different sides of the substrate 21, and the ground contact 23 and the remaining contacts 22 are located on the same side of the substrate 21. When the ground contact 23 and the remaining contacts 22 are located on the same side of the substrate 21, an empty space 25 can be provided between the ground contact 23 and the remaining contacts 22 in the present embodiment. In this way, when the chip 20 is used, ink or other impurities can be accommodated in the empty space 25, so that the impurities do not adhere to the two contacts of the chip 20 to cause short circuit.
