[0059] In order to make the purpose, technical solution and advantages of the present application more obvious, the exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the exemplary embodiments described here.

[0060] An embodiment of the present application provides a conductive component.

[0061] Please refer to Figure 1 and Figure 2 , Figure 1 A schematic diagram of the structure of a conductive component provided in an embodiment of the present application, Figure 2 for Figure 1 The top view of the conductive part shown. Figure 1 and Figure 2 As shown, the conductive component 100 includes: a plurality of conductive members 110; wherein the conductive members 110 include electrical contacts 111, in other words, the conductive members 110 can be electrically connected to other conductive objects through the electrical contacts 111. For example, the conductive member 110 can be electrically connected to a power supply device (for example, the power supply member 210 or the power source in the image forming device 200) through the electrical contacts 111, and / or, can also be electrically connected to a powered device (for example, a load member in the processing box 300, or a load member in the conductive component 100) through the electrical contacts 111, which will not be described in detail. Specifically, the electrical contacts 111 are the portions of the conductive member 110 that are in contact with and electrically connected to the power supply device.

[0062] It should be understood that Figure 1 Three conductive members 110 are shown, which can be respectively recorded as: a first conductive member 110-1, a second conductive member 110-2, and a third conductive member 110-3; accordingly, Figure 1 Three electrical contacts 111 are also shown, namely: a first electrical contact 111-1, a second electrical contact 111-2, and a third electrical contact 111-3. It should be understood that Figure 1 This is only for illustration, and in actual scenarios, there may be more or fewer conductive members 110, and the present application has no particular limitation on this. In the following text, for the sake of convenience, three conductive members 110 are still used as an example for explanation.

[0063] In the embodiment of the present application, the first projection lengths of at least two of the plurality of electrical contacts 111 in the second direction (denoted as D2) are different. The first projection length is the length between the first projection position A1 and the second projection position A2; the first projection position A1 is the projection position of the electrical contact 111 in the second direction; the second projection position A2 is the projection position of the first reference position 113 in the second direction.

[0064] It should be noted that the first projection position A1 refers to the projection position obtained by projecting the electrical contact 111 onto the second direction (a line) or the plane where the second direction is located. Further, it can be the projection position obtained by projecting the electrical contact 111 onto the plane where the second direction and the first direction are located, such as Figure 1 In actual scenarios, the electrical contact 111 can be projected along a direction perpendicular to the plane where the second direction is located (e.g., the third direction mentioned later, denoted as D3) to obtain the relevant projection position. Similarly, the second projection position A2 refers to the projection position obtained by projecting the first reference position 113 onto the second direction or the plane where the second direction is located. Furthermore, it can be the projection position obtained by projecting the first reference position 113 onto the plane where the second direction and the first direction are located, such as Figure 1 As shown in the figure, no further description is given.

[0065] In the embodiment of the present application, the second direction is parallel to the axial direction of the roller. The second direction intersects with the first direction (denoted as D1). It is possible that, with the D1 direction as a reference, the angle between the D2 direction and the D1 direction is between 45° and 135°. For example, the angle between D2 and D1 may be at least one of 45°, 60°, 75°, 90°, 105°, 120°, and 135°. Of course, the angle between D2 and D1 may also be any other value within the range of 45° to 135°. In a preferred embodiment, the second direction and the first direction may be perpendicular to each other. In the embodiment of the present application, the first direction is related to the application scenario of the conductive component 100.

[0066] Exemplarily, the above-mentioned conductive component 100 can be applied to the installation matching scenario of the processing box 300 and the image forming device 200. Among them, the image forming device 200 may include but is not limited to: a printing device (or a printer), and the processing box 300 may be any box body that can be detachably installed in the image forming device 200, and the box body can be electrically connected to the image forming device 200 through the conductive component 100. Exemplarily, the processing box 300 involved in the embodiment of the present application may include but is not limited to: a developing box (or a developing assembly), a drum box, etc., which are not exhaustive. In this embodiment, the conductive component 100 can be used to realize the electrical connection between the load member 310 in the processing box 300 and the power supply member 210 in the image forming device 200.

[0067] There may be multiple load members 310 in the processing box 300, which may include but are not limited to at least one of the following: a roller member 311, a powder discharge knife, a fixed resistor, and a variable resistor. Specifically, at least one roller member 311 includes a developing roller, and in addition, it may also include but is not limited to a powder feeding roller, a photosensitive drum, etc., which are not exhaustive. In a possible embodiment, the roller member 311 includes a developing roller and / or a powder feeding roller and / or a photosensitive drum.

[0068] Specifically, if Figure 3 As shown, the image forming device 200 has an installation cavity inside, and the imaging component 230 and the processing box 300 (or called the developing component) need to be installed in the installation cavity respectively, wherein the imaging component 230 needs to be installed in the installation cavity first, and then the developing component is installed. The imaging component 230 is provided with a photosensitive drum (OPC), and the developing component is provided with a developing roller; when the imaging component 230 and the developing component are installed in place in the installation cavity, the developing roller and the photosensitive drum need to be arranged oppositely, and the two can be in contact or not in contact. When printing or other image forming processes are performed, the toner on the developing roller can be adsorbed to the surface of the photosensitive drum. In addition to the developing roller, the developing component also has a powder feeding roller and a powder discharge knife. The shell of the developing component also has a receiving cavity for accommodating toner. The function of the powder feeding roller is to transport the toner in the receiving cavity to the developing roller. The developing roller is charged and can absorb toner. The powder discharge knife is used to scrape the toner on the surface of the developing roller so that the toner on the surface of the developing roller is evenly distributed, thereby ensuring that all areas on the surface of the photosensitive drum can evenly absorb toner. In one application scenario, the above-mentioned load components 310 need to work with electricity, so the electrical connection between the above-mentioned load components 310 and the power supply or power supply component 210 can be achieved through the electrical contacts in the conductive component 100.

[0069] In this scenario, the conductive component 100 provided in the embodiment of the present application can be used to be set on the processing box 300 or the image forming device 200, and the processing box 300 can be detachably installed in the body of the image forming device 200. The conductive component 100 is used to realize the electrical connection between the power supply 210 of the image forming device 200 and the load member 310 of the processing box 300, and at least one load member 310 includes a roller member 311. In this way, the electrical contact 111 in the conductive member 110 can be used to contact the power supply 210 to connect to the power supply. Moreover, in the embodiment of the present application, at least two of the multiple electrical contacts 111 have different first projection lengths in the second direction. In this embodiment, the second direction is arranged to intersect with the first direction, the second direction is parallel to the axial direction of the roller member, and the first direction is the installation direction of the processing box 300.

[0070] It should be noted that, in the example of the present application, the first reference position 113 is any point on the side of the conductive component 100 away from the electrical contact 111. In specific implementation, the first reference position 113 may be a position on the conductive component 100, and the position is away from the electrical contact 111 in the second direction. Exemplarily, if the conductive component 100 is a cubic structure, and the electrical contact 111 is located on the left side of the conductive component 100, the second direction may be perpendicular to the left side, for example, parallel to the bottom surface or the front side of the conductive component 100, and the first reference position 122 may be any position on the conductive component 100 located on the right side of the left side, for example, any point on the right side of the conductive component 100. In actual scenarios, the first reference position 113 may be custom selected or configured, and its projection position in the second direction (i.e., the second projection position) may be fixed.

[0071] It should be noted that the conductive component 100 can be an independent device independent of the processing box 300 and the image forming device 200; or, the conductive component 100 can also be set on the processing box 300 as a part of the processing box 300, and is used to realize the electrical connection between the load component 310 and the power supply component 210 in the processing box 300; or, the conductive component 100 can also be set on the image forming device 200 as a part of the image forming device 200, and is used to achieve installation alignment with the processing box 300.

[0072] When the process box 300 is used to be installed in the image forming device 200 and is specifically used for developing capability, one end of the roller member 311 can be specifically a conductive member 110, and the conductive member 110 has an electrical contact 111, or one end of the roller member 311 can be electrically connected to the electrical contact 111 through a connecting member, so that when the process box 300 is installed through the conductive member 100, the roller member 311 can be electrically connected to the power supply through the electrical contact 111 and the power supply member 210, so as to be powered on and started. In actual scenarios, the roller member 311 (especially the developing roller) generally intersects with the plane where the electrical contact 111 is located and is fixedly arranged; preferably, in order to facilitate electrical connection, the roller member 311 can be perpendicular to the plane where the electrical contact 111 is located. In the embodiment of the present application, the fixed roller member 311 is used as a reference, and the second direction is determined based on the axial direction of the roller member 311. That is, the second direction is parallel to the axial direction of the roller member 311. In a preferred embodiment, the second direction is parallel to the axial direction of the developing roller.

[0073] Moreover, in the embodiment of the present application, the first direction is the installation direction of the processing box 300. In order to achieve installation matching between the processing box 300 and the image forming device 200, the first direction is related to the architecture of the image forming device 200. For different image forming devices 200, the first direction is also correspondingly different to achieve installation adaptation between the two.

[0074] Combination Figure 3 and Figure 4 Let’s take an example. Figure 4 As shown, the body of the image forming device 200 includes an inner plate 220, and a guide groove 221 is provided on the inner plate 220. The guide groove 221 is used to guide the installation direction of the processing box 300. Specifically, at least one of the conductive members 110 can generally be protruded (that is, protruding from the side of the conductive member 100 where it is located). When installing the processing box 300, the conductive member 110 can extend into the guide groove 221 and slide along the guide groove 221. In this way, the processing box 300 can be detachably installed in the image forming device 200 by pulling and inserting. The structure after installation can refer to Figure 3 shown.

[0075] Furthermore, in the embodiments of the present application, Figure 5 As shown, the image forming device 200 is further provided with a plurality of power supply members 210, and the first projection lengths formed in the second direction by at least two of the contact portions 211 of the plurality of power supply members 210 are different, and for a group of power supply members 210 and conductive members 110 that can be adapted under normal installation conditions, if the first projection length formed in the second direction by the contact portion 210 of the power supply member 210 is longer, the first projection length formed in the second direction by the corresponding electrical contact 111 of the conductive member 110 is shorter.

[0076] For example, Figure 5 A possible embodiment is shown, in which at least two of the contact portions 211 of the plurality of power supply members 210 have different first projection lengths in the second direction, and the lengths increase in sequence along the first direction; and at least two of the electrical contacts 111 of the conductive member 110 in the conductive member 100 have different first projection lengths in the second direction, and the arrangement sequence decreases in sequence along the first direction. In this way, when the conductive member 100 or the processing box 300 provided with the conductive member 100 is correctly installed with the image forming device 200, the following can be formed: Figure 4 The electrical connections shown.

[0077] In other words, the position of the electrical contact 111 can match the power supply 210, so that after the two are installed and matched, the electrical contact 111 can contact and electrically connect with the power supply 210. In this embodiment, the first direction can also be specifically understood as the insertion and extraction direction of the process cartridge 300, and can also be understood as the extension direction of the guide groove 221 in the image forming device 200, wherein the guide groove 221 is provided on the inner side plate 220 for guiding the installation direction of the process cartridge 300. In other words, the installation direction of the process cartridge 300 is parallel to the extension direction of the guide groove 221.

[0078] In this way, at least two of the multiple electrical contacts 111 have different first projection lengths in the second direction, which can make the lengths of at least two conductive members 110 in the axial direction of the roller member different. In this way, by matching the length of the conductive member 110 with the length of the image forming device 200, the conductive member 110 and the power supply member 210 can be accurately positioned and matched. Therefore, under the premise that the electrical contact 111 and the contact portion 211 of the power supply member are in contact and conductive, the length of the conductive member 110 in the second direction that needs to be set is used to assist in achieving positioning matching. Not only is the conductive performance and stability good, but in some embodiments, the positioning member can be omitted or there is no special precision requirement and cost for the positioning member. In summary, the technical solution provided by the present application can achieve positioning assistance while achieving conductive capability, which is conducive to improving positioning accuracy.

[0079] In order to further illustrate possible forms of the first direction, the following takes the case where the conductive component 100 is disposed on the process box 300 as an example, and illustrates the specific structure of the process box 300 .

[0080] In an exemplary embodiment, the first direction is parallel to the direction of the line connecting the third projection position and the fourth projection position, the processing box 300 includes a positioning member 320, the third projection position is the projection position of the axis of the roller member 311 along the second direction, and the fourth projection position is the projection position of the positioning member 320 along the second direction. In this embodiment, the third projection position and the fourth projection position are the positions determined by projecting the relevant device along the second direction on a plane perpendicular to the second direction. In actual scenarios, the conductive component 100 is generally also provided with a positioning member 320, and the positioning member 320 generally presents a convex or concave shape, which is used to locate the installation position of the processing box 300 during installation. For example, the positioning member 320 can be specifically a positioning protrusion. When the processing box 300 is inserted into the image forming device 200 along the installation direction, the positioning protrusion can be partially engaged with the positioning recess in the image forming device 200, such as the above-mentioned guide groove 221, to achieve the installation positioning function. In actual scenarios, the positioning member 320 can be arranged on the same side as the electrical contact 111 , or on the opposite side of the processing box 300 .

[0081] Alternatively, in another exemplary embodiment, the processing box 300 includes an information processing device 330, such as Figure 7 As shown, the information processing device 330 includes a plurality of functional electrical contacts 331, and the first direction is parallel to the sequential arrangement direction of the plurality of functional electrical contacts 331. The information processing device 330 can be specifically any device or component with information processing capability in the processing box 300. For example, the information processing device 330 can include but is not limited to: a chip. The information processing device 330 can realize one or more transmissions of information, instructions, etc. with other devices through the functional electrical contacts 331. For details, please refer to Figure 6The information processing device 330 may have four functional electrical contacts 331, namely a power contact (Volt Current Condenser, VCC), a data signal contact (Serial Data, SDA), a clock signal contact (Clock, CLK), and a ground contact (Ground, GND). The four functional electrical contacts 331 are respectively used to contact four electrical contact parts on the image forming device, such as conductive springs, contact pins, electrical contacts, etc., and the above four functional electrical contacts 331 are arranged in sequence along the same direction, and the first direction is parallel to the direction in which the above four functional electrical contacts 331 are arranged in sequence.

[0082] It is understandable that the information processing device has a plurality of conductive terminals, and the conductive terminals may be in different shapes such as square, circular, etc. Figure 6 As shown in FIG. 1 , the functional electrical contact 331 is a portion of the conductive terminal used for contacting an electrical contact portion of the image forming device.

[0083] The information processing device 330 may have other types of terminals that are not in direct contact with the electrical contact portion of the image forming device. In this case, such terminals may be arranged in the same direction as the above-mentioned conductive terminals; or may not be arranged in the same direction as the above-mentioned conductive terminals.

[0084] Of course, based on different situations, the number of functional electrical contacts 331 on the information processing device 330 may be other, such as greater than four or less than four.

[0085] In addition, the processing box 300 generally has a plurality of outer wall surfaces, and the information processing device 330 can be disposed at a connection between different outer wall surfaces of the processing box 300 or at any outer wall surface.

[0086] Alternatively, in another exemplary embodiment, the processing box 300 includes an information processing device 330, and the information processing device 330 includes a plurality of functional electrical contacts 331. The first direction is parallel to the direction of the line connecting the first projection position and the third projection position. The first projection position is the projection position of the axis of the roller 311 along the second direction, and the third projection position is the projection position of the functional electrical contact 331 along the second direction. The processing box 300 has a first end face and a second end face respectively located at both ends of the roller, and at least one functional electrical contact 331 is located on the first end face or the second end face. The functional electrical contact 331 located on the first end face or the second end face is projected along the third direction to form a third projection position.

[0087] Specifically, the information processing device 330 may have four functional electrical contacts 331, namely, a power contact (VoltCurrent Condenser, VCC), a data signal contact (Serial Data, SDA), a clock signal contact (Clock, CLK), and a ground contact (Ground, GND). The four functional electrical contacts 331 are respectively used to contact four electrical contact parts on the image forming device, such as conductive springs, contact pins, electrical contacts, etc. Among them, at least one of the four functional electrical contacts 331 is located on the first end surface or the second end surface.

[0088] Likewise, the information processing device 330 may have other types of terminals that are not in direct contact with the electrical contact portion of the image forming device, and such terminals cannot be used to project the third projection position.

[0089] It should be noted that when it is necessary to determine the direction or length through different projection positions projected along the same projection direction, the above projection positions should be located in the same projection plane perpendicular to the above projection direction. Similarly, when it is necessary to determine whether different projections projected along the same projection direction have positional overlap or a specific positional relationship, the above projections should also be located in the same projection plane perpendicular to the above projection direction.

[0090] In the embodiment of the present application, at least two of the plurality of electrical contacts 111 have first projection lengths in the second direction. In a specific implementation, the conductive component 100 may have a plurality of electrical contacts 111, and the first projection lengths of the plurality of electrical contacts 111 in the second direction may be different or partially the same. Figure 1 , Figure 2 and Figure 4 As shown, the first projection lengths of the plurality of electrical contacts 111 in the second direction are all different. For another example, in some possible embodiments, one of the plurality of electrical contacts 111 has the longest first projection length in the second direction, and the remaining one or more electrical contacts 111 have the same first projection length in the second direction.

[0091] In an actual implementation scenario, the first projection lengths of the plurality of electrical contacts 111 may be set to increase or decrease in a certain order, such as in the first direction and / or the third direction.

[0092] In an exemplary embodiment, at least two of the multiple electrical contacts 111 are spaced apart along the first direction; and the first projection lengths of at least two of the multiple electrical contacts 111 in the second direction decrease sequentially according to the arrangement order of the corresponding electrical contacts 111 along the first direction. Figure 4In this embodiment, since the first projection lengths of the electrical contacts 111 in the second direction are different, during the installation process of the conductive component 100 or the processing box 300 provided with the conductive component 100, in addition to achieving the effect of contact conduction or auxiliary positioning, it can also further prevent the electrical contacts 111 from scratching the contact portion 211 of the power supply member 210, avoid unnecessary scratching contact during a single installation process, reduce the unstable power supply caused by frequent scratching, and help to further improve the power supply stability.

[0093] In addition, the first projection length corresponding to each electrical contact 111 may be greater than, equal to, or less than the second projection length, wherein the second projection length is the distance between the second projection position and the plane where the electrical contact is located (e.g., the left side in the previous text). Generally, the first projection length of at least one of the plurality of electrical contacts in the second direction is greater than the second projection length. In other words, generally, at least one of the plurality of electrical contacts may be protruding from the plane where it is located. Figure 1 and Figure 5 Take the situation shown as an example, Figure 5 The electrical contacts 111 of the three conductive members 110 may all be protruding from the plane of the conductive component 100 where the conductive members 110 are located; or, Figure 1 and Figure 5 Among the three electrical contacts 111 of the conductive members 110, only one electrical contact 111 may be protruding, and the other electrical contacts 111 may be flush with the plane of the conductive component 100 where the conductive member 110 is located or further recessed, which will not be described in detail.

[0094] In addition, the embodiment of the present application has no particular restrictions on the arrangement relationship of the plurality of electrical contacts 111 in the first direction and the third direction. In actual implementation scenarios, the plurality of electrical contacts 111 may be arranged at intervals in the first direction and / or the third direction.

[0095] In an exemplary embodiment, as described above Figure 1 and Figure 5 As shown, multiple electrical contacts 111 can be arranged at intervals along the first direction. In this embodiment, multiple electrical contacts 111 can be arranged flush in the second direction, or can also be arranged at intervals. Wherein, the interval arrangement can be arranged in a certain physical space when specifically implemented, or, in a preferred solution, can also be arranged by providing insulating materials to prevent problems such as short circuit or breakdown.

[0096] In addition, in the embodiment of the present application, the projection positions of the plurality of electrical contacts 111 in the conductive component 100 in the second direction may be relatively close.

[0097] In an exemplary embodiment, the projection positions of at least two of the plurality of electrical contacts 111 along the first direction at least partially overlap.

[0098] Alternatively, in another possible embodiment, the projection positions of at least two of the multiple electrical contacts 111 along the first direction at least partially overlap with the first area; wherein the first area is the projection area of ​​the outer contour of the roller shaft of the roller member 311 in the first direction. In specific implementation, when the processing box 300 is specifically a developing assembly, the developing roller is the most important developing device in the developing assembly, and the position of the developing roller in the developing assembly is relatively fixed, and the spatial position of each electrical contact 111 can be designed based on this; in other words, in this embodiment, the roller member 311 can be specifically a developing roller. At this time, you can refer to Figure 8 ,like Figure 8 As shown, from the axial direction of the developing roller (the third direction, which is also the side view of the conductive component 100), the developing roller can be composed of an inner ring roller shaft and an outer ring protection structure, and the projection of the outer contour of the roller shaft of the developing roller in the first direction is: the interval [A, B] between point A and point B. In this embodiment, the projection positions of at least two of the multiple electrical contacts 111 along the first direction at least partially overlap with the interval [A, B]. In this way, the multiple electrical contacts 111 can be arranged not far apart in the second direction and spaced apart in the first direction, such as Figure 8 As shown, the plurality of electrical contacts 111 as a whole present an effect of being arranged horizontally in the first direction.

[0146] In addition, exemplary, the movable setting can also be realized by the elastic conductive part 112. In an exemplary embodiment, in the processing box 300, at least two of the multiple conductive members 110 include the elastic conductive part 112, and the elastic conductive part 112 is used to contact with the power supply member 210 to connect to the power supply.

[0164] In addition, in another possible embodiment of the present application, the projection positions of at least two of the multiple power supply components 210 in the image forming device 200 along the first direction at least partially overlap; or, the projection positions of at least two of the multiple power supply components 210 along the first direction at least partially overlap with the first area.

[0165] In addition, in another possible embodiment of the present application, a plurality of power supply members 210 in the image forming device 200 are arranged at intervals in the third direction and / or the first direction. The third direction intersects the first direction and the second direction. Preferably, the third direction can be perpendicular to the first direction and the second direction respectively. Moreover, in the installation scenario of the process cartridge 300, the third direction can also be parallel to the axial direction of the roller member 311. No further description is given.

[0166] Further, in the specific implementation of the embodiment of the present application, the multiple power supply members 210 may include: a first power supply member 210-1, a second power supply member 210-2 and a third power supply member 210-3. In one implementation, the first power supply member 210-1 may be recessed in the second direction relative to the second power supply member 210-2 and the third power supply member 210-3; in order to adapt to the power supply structure design of the image forming device 200, the first electrical contact 111-1 in the conductive component 100 may also be protruded in the second direction relative to the second electrical contact 111-2 and the third electrical contact 111-3. Alternatively, in another implementation, the distance between the second power supply member 210-2 and the first power supply member 210-1 or the third power supply member 210-3 recessed in the second direction increases or decreases in sequence; accordingly, in order to adapt to the design, the distance between the second electrical contact 111-2 in the conductive component 100 and the first electrical contact 111-1 or the third electrical contact 111-3 protruding in the second direction increases or decreases in sequence.

[0167] For the image forming device 200, the positions of the multiple power supply members 210 in the image forming device 200 are generally fixed by design. Based on the above design, when the conductive component 100 or the processing box 300 provided with the conductive component 100 is installed in the image forming device 200, by designing that the first projection lengths of at least two of the multiple electrical contacts in the second direction are different, the lengths of at least two conductive members in the axial direction of the roller member can be different. In this way, by matching the length of the conductive member with the length of the image forming device, it is possible to achieve precise positioning matching of the conductive member and the power supply member. Therefore, under the premise that the electrical contacts and the power supply member are in contact and conductive, the length of the conductive member in the second direction that needs to be set is used to assist in achieving positioning matching. Not only is the conductive performance and stability good, but in some embodiments, the positioning member can be omitted or there is no special precision requirement and cost for the positioning member. In summary, the technical solution provided by the present application can achieve positioning assistance while achieving conductive capability, which is conducive to improving positioning accuracy.
