DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] 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 technical features indicated. 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 utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0041] 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 connection; 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.

[0042] In the present utility model, 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.

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.

[0044] As described in the background technology, when the ink cartridge accidentally falls, the conductive member may be misplaced or fall off, affecting the communication between the ink cartridge and the image forming device, causing the ink cartridge to be unable to be used normally. The inventor has found through research that the reason for this problem is that the conductive member is connected to the electrical connector, most of the conductive member is exposed outside the electrical connector, and the part where the conductive member is connected to the electrical connector is also exposed outside the electrical connector. When the ink cartridge accidentally falls, the part where the conductive member is connected to the electrical connector is not protected and is hit, which may cause the conductive member to be misplaced or fall off, affecting the communication between the ink cartridge and the image forming device, causing the ink cartridge to be unable to be used normally.

[0045] In order to solve the above problems, the embodiment of the utility model provides an electrical connection assembly and an ink cartridge, including a receiving member and an electrical connector and a conductive member arranged on the receiving member; the conductive member has an inner fitting portion, and the inner fitting portion is engaged with the receiving member to fix the conductive member; the conductive member has a shielding area that overlaps with the electrical connector and an exposed area that does not overlap with the electrical connector, and the inner fitting portion is located in the shielding area. The conductive member can be fixed by engaging the inner fitting portion of the conductive member with the receiving member, and the shielding area including the inner fitting portion is shielded by the electrical connector, so that the conductive member can be effectively protected and the inner fitting portion can be prevented from being hit, so that when the ink cartridge accidentally falls, the conductive member can be prevented from being misplaced or falling off, and abnormal communication between the ink cartridge and the image forming device can be prevented, thereby ensuring the normal use of the ink cartridge.

[0046] The electrical connection assembly and ink cartridge provided by the utility model are described in detail below in conjunction with specific embodiments.

[0047] like Figures 1 to 4 As shown, an embodiment of the utility model provides an electrical connection component, which is applied to an ink cartridge, including a receiving component 10 and an electrical connector 20 and a conductive member 30 arranged on the receiving component 10; the electrical connector 20 has an external surface 201, and the external surface 201 is located on the side of the electrical connector 20 that is away from the conductive member 30 and the receiving component 10, and an external terminal 203 for contacting a contact pin corresponding to an image forming device is arranged on the external surface 201; the electrical connector 20 is also provided with an internal terminal 204, and the conductive member 30 has an internal matching portion 302, a first connecting portion 303 contacting the internal terminal 204 and a second connecting portion 304 for contacting a contact pin corresponding to the image forming device, and the internal matching portion 302 is engaged with the receiving component 10 to fix the conductive member 30.

[0048] When observed in a direction perpendicular to the external connection surface 201, the conductive member 30 has a shielding area that overlaps with the electrical connector 20 and an exposed area 301 that does not overlap with the electrical connector. The first connecting portion 303 and the inner mating portion 302 are located in the shielding area, and the second connecting portion 304 is at least partially located in the exposed area 301. The area of ​​the shielding area is larger than that of the exposed area 301.

[0049] A rectangular coordinate system is established for the ink cartridge, the length direction of the ink cartridge is the X direction, the width direction of the ink cartridge is the Y direction, the height direction of the ink cartridge is the Z direction, and the X axis, the Y axis and the Z axis are perpendicular to each other.

[0050] The receiving member 10 is fixedly connected to the ink cartridge housing 40. The electrical connector 20 and the conductive member 30 are connected to the receiving member 10 respectively.

[0051] The external surface 201 may be a plane. In a direction perpendicular to the external surface 201, the conductive member 30 and the receiving member 10 are located on the side of the external surface 201 facing the housing 40. The internal terminal 204 is located on the side of the electrical connector 20 facing away from the external surface 201. The direction perpendicular to the external surface 201 may be the X-axis direction.

[0052] The conductive member 30 is a metal member. The internal connection terminal 204 of the electrical connection member 20 can contact with the contact pin corresponding to the image forming device through the first connection part 303 and the second connection part 304 .

[0053] The inner fitting portion 302 of the conductive member 30 engages with the receiving member 10 to fix the conductive member 30 , thereby keeping the conductive member 30 and the receiving member 10 fixed.

[0054] like Figure 1 As shown, when observing the electrical connection assembly from a direction perpendicular to the external surface 201 (i.e., -X direction), the area where the conductive member 30 is blocked by the electrical connector 20 is the blocked area, that is, the area where the conductive member 30 overlaps with the electrical connector 20 is the blocked area. It can be understood that when observing the electrical connection assembly from a direction perpendicular to the external surface 201 and toward the electrical connector 20, the blocked area cannot be seen, that is, the blocked area is blocked by the electrical connector 20; when observing the electrical connection assembly from a direction perpendicular to the external surface 201, the area where the conductive member 30 is not blocked by the electrical connector 20 is the exposed area 301, that is, the area where the conductive member 30 does not overlap with the electrical connector 20 is the exposed area 301. It can be understood that when observing the electrical connection assembly from a direction perpendicular to the external surface 201 and toward the electrical connector 20, the exposed area 301 can be seen, that is, the exposed area 301 is not blocked by the electrical connector 20. It should be noted that Figure 3 The area enclosed by the dotted line in FIG. 1 is the exposed area 301 of the conductive member 30 in the first embodiment. Figure 3The area except the area surrounded by the dotted line is the shielding area of ​​the conductive member 30 in the first embodiment; Figure 8 The area enclosed by the dotted line in is the exposed area 301 of the conductive member 30 in the second embodiment. Figure 8 The area except the area surrounded by the dotted line is the shielding area of ​​the conductive member 30 in the second embodiment; Fig.11 The area enclosed by the dotted line in FIG. 1 is the exposed area 301 of the conductive member 30 in the third embodiment. Fig.11 The area except the area surrounded by the dotted line is the shielding area of ​​the conductive member 30 in the third embodiment.

[0055] The first connection part 303 and the inner matching part 302 are located in the shielding area, so that the electrical connector 20 can protect the first connection part 303 and the inner matching part 302; the second connection part 304 is at least partially located in the exposed area 301, so that the second connection part 304 can contact the contact pin corresponding to the image forming device.

[0056] The area of ​​the shielding region is larger than the area of ​​the exposed region 301 , so that most of the area of ​​the conductive member 30 can be shielded by the electrical connector 20 , thereby effectively protecting the conductive member 30 .

[0057] The electrical connection assembly provided by the embodiment of the utility model can fix the conductive member 30 by engaging the inner fitting portion 302 of the conductive member 30 with the receiving component 10, and can effectively protect the conductive member 30 by shielding the shielding area including the inner fitting portion 302 through the electrical connection member 20, and can prevent the inner fitting portion 302 from being hit, so that when the ink cartridge accidentally falls, the conductive member 30 can be prevented from being misplaced or falling off, and abnormal communication between the ink cartridge and the image forming device can be prevented, thereby ensuring the normal use of the ink cartridge.

[0058] In a possible implementation manner, the inner fitting portion 302 is fixedly connected to the receiving component 10 .

[0059] The connection method between the inner matching part 302 and the receiving member 10 includes but is not limited to at least one of welding, clamping, and bonding. The number of the inner matching part 302 can be one or more.

[0060] like Figure 2 As shown, the receiving member 10 is provided with first engaging portions 101 engaged with the inner fitting portions 302. The number of the first engaging portions 101 is equal to the number of the inner fitting portions 302.

[0061] In a first optional implementation, if Figure 2 and Figure 3As shown, the inner fitting part 302 can be a first positioning hole, and the number of the inner fitting parts 302 is two. The first joining part 101 can be a first positioning column, and the number of the first joining parts 101 is two. The two first positioning columns are respectively located on both sides of the receiving component 10 in the width direction of the ink cartridge. After each first positioning hole is matched with a first positioning column, the first positioning column is subjected to hot melt deformation treatment, so that the inner fitting part 302 can be welded and connected with the first joining part 101, thereby fixing the conductive part 30.

[0062] The electrical connection assembly of the second embodiment differs from the electrical connection assembly of the first embodiment in that the structures of the receiving member 10 and the conductive member 30 are different, while the structure of the electrical connection member 20 of the electrical connection assembly of the second embodiment is the same as that of the electrical connection member 20 of the first embodiment.

[0063] In a second alternative implementation, if Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the inner fitting part 302 can be a snap-fit ​​plate, and the number of the inner fitting parts 302 is two. The first engaging part 101 can be a snap-fit ​​hole, and the number of the first engaging parts 101 is two. The two snap-fit ​​holes are respectively located on both sides of the receiving component 10 in the width direction of the ink cartridge, and the two snap-fit ​​holes extend along the width direction of the ink cartridge. Each snap-fit ​​plate is snapped into a snap-fit ​​hole, so that the inner fitting part 302 can be snap-fitted and connected with the first engaging part 101, thereby fixing the conductive part 30.

[0064] The electrical connection assembly of the third embodiment differs from the electrical connection assembly of the first embodiment in that the structures of the receiving member 10 and the conductive member 30 are different, while the structure of the electrical connection member 20 of the electrical connection assembly of the third embodiment is the same as that of the electrical connection member 20 of the first embodiment.

[0065] In a third alternative embodiment, if Fig. 9 and Fig.11 As shown, the inner fitting part 302 can be a first positioning hole, and the number of the inner fitting parts 302 is two. The first joining part 101 can be a first positioning column, and the number of the first joining parts 101 is two. The two first positioning columns are located on one side of the receiving component 10 in the length direction of the ink cartridge. After each first positioning hole is matched with a first positioning column, the first positioning column is subjected to a hot melt deformation treatment, so that the inner fitting part 302 can be welded and connected with the first joining part 101, thereby fixing the conductive part 30.

[0066] In a possible implementation manner, the electrical connector 20 is configured to be assembled with the receiving member 10 after the conductive member 30 is assembled with the receiving member 10 .

[0067] The electrical connector 20 and the conductive member 30 are not fixed to each other, so the electrical connector 20 and the conductive member 30 cannot be preassembled into a component and then assembled with the receiving member 10 . That is, the electrical connector 20 and the conductive member 30 need to be installed separately.

[0068] like Figure 1 and Figure 2 As shown, when installing the electrical connector 20 and the conductive member 30, the conductive member 30 is first assembled with the receiving member 10, and then the electrical connector 20 is assembled with the receiving member 10. It should be noted that when the electrical connector 20 is assembled with the receiving member 10 before the conductive member 30, the conductive member 30 cannot be assembled with the receiving member 10 due to the small space between the electrical connector 20 and the receiving member 10. Therefore, the installation order of the electrical connector 20 and the conductive member 30 is to install the electrical connector 20 first and then install the conductive member 30.

[0069] It should be noted that the installation sequence of the electrical connector 20 and the conductive member 30 in the second and third embodiments is the same as that of the first embodiment, that is, the electrical connector 20 is installed first, and then the conductive member 30 is installed.

[0070] In a possible implementation, Figures 1 to 4 As shown, the electrical connector 20 has a hollowed-out avoidance portion 205 , and when viewed in a direction perpendicular to the external connection surface 201 , the projection of the exposed area 301 is located within the projection area of ​​the avoidance portion 205 .

[0071] Among them, Figure 4 As shown, the avoidance portion 205 penetrates the electrical connector 20 in a direction perpendicular to the external connection surface 201 .

[0072] When the electrical connection assembly is observed from a direction perpendicular to the external connection surface 201 and toward the electrical connector 20 , the exposed area 301 can be seen through the avoidance portion 205 .

[0073] In a possible implementation, Figure 4 As shown, the electrical connector 20 further has an inner surface 202 parallel to the outer surface 201 , and the second connecting portion 304 can be disposed between the outer surface 201 and the inner surface 202 .

[0074] The internal terminal 204 is located on the inner surface 202 .

[0075] In a possible implementation, Figure 3 As shown, the conductive member 30 includes a body 31 and at least one elastic body 32 , the elastic body 32 is connected to the body 31 , and the second connecting portion 304 is located on one elastic body 32 of the conductive member 30 .

[0076] The main body 31 is in contact with the receiving member 10 , and the inner matching portion 302 is disposed on the main body 31 .

[0077] The elastic body 32 does not contact the receiving member 10, and the elastic body 32 can be elastically deformed. The shape of the elastic body 32 can be L-shaped.

[0078] In an optional embodiment, the conductive member 30 includes a main body 31 and two elastomers 32, the two elastomers 32 are respectively a first elastomer and a second elastomer, the first elastomer and the second elastomer are respectively connected to the main body 31, the portion of the first elastomer in contact with the internal terminal 204 is the first connecting portion 303, and the portion of the second elastomer in contact with the contact pin of the image forming device is the second connecting portion 304.

[0079] In a possible implementation, the edge of the electrical connector 20 abuts against the elastic body 32 where the second connection portion 304 is located. In this configuration, the elastic body 32 where the second connection portion 304 is located can be squeezed by the edge of the electrical connector 20, which can improve the stability of the contact between the second connection portion 304 and the corresponding contact pin, and at the same time, when the second connection portion 304 is in contact with the corresponding contact pin, it is helpful to control the deformation amplitude and position of the elastic body 32 where the second connection portion 304 is located.

[0080] In a possible implementation, Figure 2 and Figure 4 As shown, the electrical connector 20 also has an external mating portion 206 engaged with the receiving member 10. When viewed in a direction perpendicular to the external connection surface 201, the projection of the external mating portion 206 is located outside the projection of the conductive member 30, that is, the projection of the external mating portion 206 is not within the projection area of ​​the conductive member 30.

[0081] In a possible implementation, Figure 2 As shown, the receiving member 10 includes a recessed receiving portion 102 , the conductive member 30 is at least partially located in the receiving portion 102 , and the receiving member 10 is provided with a second engaging portion 103 engaged with the outer matching portion 206 .

[0082] The portion of the receiving member 10 that is recessed toward the housing 40 is the accommodating portion 102 .

[0083] The outer fitting portion 206 is fixedly connected to the second engaging portion 103 .

[0084] The number of the outer fitting portion 206 may be one or more. The number of the second engaging portions 103 is equal to the number of the outer fitting portions 206 .

[0085] In an optional embodiment, if Figure 2 and Figure 4As shown, the outer fitting part 206 can be a second positioning hole, and the number of the outer fitting parts 206 is two. The second joining part 103 can be a second positioning column, and the number of the second joining parts 103 is two. The two positioning columns are located on one side of the receiving component 10 in the length direction of the ink cartridge. After each second positioning hole is matched with a second positioning column, the positioning column is subjected to a hot melt deformation treatment, so that the outer fitting part 206 can be welded and connected with the second joining part 103, thereby fixing the electrical connector 20.

[0086] In a possible implementation, Fig. 9 and Fig.10 As shown, the receiving component 10 includes a bracket body 11 and a receiving body 12 connected to each other, the electrical connector 20 is connected to the bracket body 11 , the receiving portion 102 is located on the bracket body 11 , and the conductive member 30 is connected to the receiving body 12 .

[0087] The receiving body 12 is fixedly connected to the shell 40 of the ink cartridge, and the bracket body 11 is fixedly connected to the receiving body 12 .

[0088] like Fig. 9 As shown, the second joint part 103 is arranged on the support body 11, and the second joint part 103 is located on one side of the support body 11 in the length direction of the ink cartridge.
