Description

[0002] In the related art, the image forming device generally adopts a method of matching a drum cartridge with multiple developer cartridges to form a color image. In order to save space, the developer cartridge can be made into a flat shape, and the high-voltage conductive contacts on the developer cartridge are arranged in sequence in the installation direction of the developer cartridge. Please refer to Figure 1 , Figure 1 Schematic diagram of the structure of the developing box in the related art. Figure 1 As shown, three high-voltage conductive contacts 1-3 are sequentially arranged on the side of the developer box along the installation direction (denoted as D1) of the developer box. When the developer box moves along the installation direction, for example, when the developer box is inserted into or pulled out of the printer, the high-voltage conductive contacts on the end side of the developer box will rub against the high-voltage power supply contacts on the printer side, causing contact wear, poor conductivity, unstable power supply, and other problems, which will further cause abnormal printer imaging.

[0061] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present application. However, it is apparent to those skilled in the art that the present application can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present application, some technical features well known in the art are not described.

[0062] An embodiment of the present application provides a conductive component.

[0063] Please refer to Figure 2 , Figure 2 Schematic diagram of a conductive component provided by an embodiment of the present disclosure. 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.

[0064] It should be understood that Figure 2 Three conductive members 110 are shown, namely: a first conductive member 110-1, a second conductive member 110-2, and a third conductive member 110-3; accordingly, Figure 2 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 2This is only for illustration, and in actual scenarios, there may be more or fewer conductive members 110, and the present disclosure 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.

[0065] In an embodiment of the present application, at least two of the multiple electrical contacts 111 are arranged at intervals along the second direction (denoted as D2). The second direction intersects with the first direction (denoted as D1) and the third direction (denoted as D3); possibly, 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 can be at least one of 45°, 60°, 75°, 90°, 105°, 120°, and 135°. Of course, the angle between D2 and D1 can also be any other value within the range of 45° to 135°. In a preferred embodiment, the second direction can be perpendicular to the first direction and the third direction. In actual scenarios, the second direction can be determined by the first direction and the third direction, and the first direction and the third direction are 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 4As 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. In addition, in the embodiment of the present application, at least two of the multiple electrical contacts 111 are arranged at intervals along the second direction, wherein the second direction intersects with the third direction and the first direction, the installation direction of the processing box 300 is the first direction, and the third direction is parallel to the axial direction of the roller member 311.

[0070] 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.

[0071] 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 third direction is determined based on the axial direction of the roller member 311. That is, the third direction is parallel to the axial direction of the roller member 311. In a preferred embodiment, the third direction is parallel to the axial direction of the developing roller.

[0072] 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 different accordingly to achieve installation adaptation between the two.

[0073] Combination Figure 3-Figure 5 Let’s take an example. Figure 3 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, the conductive member 110 can generally be protruded. 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 4 And, as Figure 3 and Figure 5 As shown, the image forming device 200 is also provided with a plurality of power supply members 210, and the power supply members 210 are also arranged at intervals along the second direction in the image forming device 200. In other words, the position of the electrical contact 111 can match the power supply member 210, so that after the two are installed and matched, the electrical contact 111 can contact and electrically connect with the power supply member 210. In this embodiment, the first direction can also be specifically understood as the insertion and extraction direction of the processing box 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, and is used to guide the installation direction of the processing box 300. In other words, the installation direction of the processing box 300 is parallel to the extension direction of the guide groove 221.

[0074] In this way, at least two of the plurality of electrical contacts 111 are arranged at intervals along the second direction, and the second direction intersects with the installation direction of the process cartridge (i.e., the first direction) and the axial direction of the roller member (i.e., the third direction). This is equivalent to the plurality of electrical contacts 111 being arranged in the thickness direction of the conductive member 100. Figure 2 As shown. Thus, when the process box 300 is pulled out and inserted from the installation direction to achieve the installation of the process box 300 to the image forming device 200, since at least two electrical contacts 111 are not arranged in sequence in the installation direction of the process box 300, the number of times the electrical contacts 111 and the power supply member 210 are in contact and scratched during a single installation of the process box 300 can be reduced, which can effectively reduce the poor power supply conductivity and unstable power supply caused by the scratching of the electrical contacts 111, and thus avoid the abnormal imaging that may be caused by this. In summary, the technical solution provided in the embodiment of the present application can reduce the number of electrical contact scratches and improve power supply stability.

[0075] 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 .

[0076] In an exemplary embodiment, the first direction is parallel to the direction of the line connecting the first projection position and the second projection position, the processing box 300 includes a positioning member 320, the first projection position is the projection position of the axis of the roller member 311 along the third direction, and the second projection position is the projection position of the positioning member 320 along the third direction. The conductive component 100 is generally also provided with a positioning member 320, and the positioning member 320 is generally in a convex or concave form, 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 set on the same side as the electrical contact 111, or it can be set on the opposite side of the processing box 300.

[0077] 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 6 The 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] Alternatively, in another exemplary embodiment, the processing box 300 includes an information processing device 330, the information processing device 330 includes a functional electrical contact 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 third direction, and the third projection position is the projection position of the functional electrical contact 331 along the third direction. The processing box 300 has a first end face and a second end face respectively located at both ends of the roller, at least one functional electrical contact 331 is located on the first end face or the second end face, and 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] In a preferred embodiment of the present application, a plurality of electrical contacts 111 are spaced apart along the second direction. In actual implementation, they can be spaced apart by a certain physical space, or, in a preferred embodiment, insulating materials can be provided to prevent problems such as short circuits or breakdowns.

[0087] Thus, in the embodiment of the present application, the plurality of electrical contacts 111 are arranged at intervals in the second direction, and the second direction intersects with the first direction. Thus, on the projection plane of the first direction, the projection positions of the plurality of electrical contacts 111 may not overlap at all, or there may be a partial overlapping area, such as the case in which the plurality of electrical contacts are respectively located on the end face and the side face of a protrusion 130 described below. Thus, during the installation of the conductive component 100 or the processing box 300 provided with the conductive component 100, when the electrical contact 111 is installed along the first direction, it will not contact with the plurality of power supply members 210 provided in the image forming device 200, thus avoiding unnecessary scratching contact during a single installation process, reducing the unstable power supply caused by frequent scratching, and helping to improve the stability of power supply.

[0088] 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, so that the three-dimensional structural relationship between the plurality of electrical contacts 111 may present an effect of longitudinal arrangement in the second direction.

[0089] Specifically, in a possible embodiment, projection positions of at least two of the plurality of electrical contacts 111 in the conductive component 100 along the second direction at least partially overlap.

[0090] Alternatively, in another possible embodiment, the projection positions of at least two of the multiple electrical contacts 111 along the second direction at least partially overlap with the first area. The first area is the projection area of ​​the outer contour of the roller shaft of the roller member 311 in the second 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. 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, denoted as D3), 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 second direction is, in the first direction, the interval [A, B] between point A and point B, and in the second direction it is related to the protruding length of the developing roller. In this embodiment, the projection positions of at least two of the multiple electrical contacts 111 along the second 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 first direction, and spaced apart in the second direction, such as Figure 8 As shown, the plurality of electrical contacts 111 as a whole present an effect of being arranged longitudinally in the second direction.

[0091] In addition, in the embodiment of the present application, at least one of the multiple electrical contacts 111 can also be protruded, that is, protruded from the plane where it is located, so that it is not only convenient for electrical connection with the power supply 210 or the power supply, but also convenient for achieving the installation and positioning of the processing box 300. Therefore, in this embodiment, the positioning member can be further omitted, and the installation and positioning between the processing box 300 and the image forming device 200 can be achieved directly through the conductive member 110. When the processing box 300 is installed, the protruding electrical contact 111 can no longer be inserted and moved forward in the installation direction, so as to achieve this installation and positioning effect.

[0092] In an exemplary embodiment, in the conductive component 100, the plurality of electrical contacts 111 include a first electrical contact 111-1, a second electrical contact 111-2 and a third electrical contact 111-3, the first electrical contact 111-1, the second electrical contact 111-2 and the third electrical contact 111-3 are located on the same side of the conductive component 100, and the first electrical contact 111-1 protrudes from the second electrical contact 111-2 or the third electrical contact 111-3 by different distances in the third direction.

[0093] For any electrical contact 111, the distance it protrudes in the third direction refers to the distance that the electrical contact protrudes from the plane of the conductive component 100 where it is located. The protruding distance can be determined based on the plane of the conductive component 100 where the electrical contact is located, or it can also be determined by using any point on the conductive component 100 that is far away from the electrical contact in the third direction as a reference to determine the length of each electrical contact relative to the reference point. In actual scenarios, at least one of the multiple electrical contacts 111 can be protruding to implement this solution. In addition, in other possible embodiments, there can also be electrical contacts among the multiple electrical contacts 111 that are flush with the plane of the conductive component 100 where they are located, or there can also be electrical contacts that are recessed relative to the plane of the conductive component 100 where the electrical contacts are located.

[0094] The embodiment of the present application has no particular restrictions on the protruding distance value, arrangement relationship, etc. of each of the electrical contacts 111 in the third direction.

[0095] In a preferred embodiment, the first electrical contact 111-1 in the conductive component 100 is protruded in the third direction relative to the second electrical contact 111-2 and the third electrical contact 111-3. In this embodiment, among the three electrical contacts 111 in the conductive component 100, at least one electrical contact has a longer protruding length; the other two electrical contacts can also be protruding, but the protruding length is shorter, and the protruding lengths of the second electrical contact 111-2 and the third electrical contact 111-3 can be the same or different; or, the second electrical contact 111-2 can also be flush with the plane or recessed, and the third electrical contact 111-3 can also be flush with the plane or recessed. No further details are given. The embodiment of the present application has no special restrictions on the position of the first electrical contact 111-1. For example, the first electrical contact 111-1 can be in the first position, the second position, and the third position from top to bottom in the third direction without special restrictions.

[0096] Alternatively, in another preferred embodiment, the distances of the second electrical contact and the first electrical contact or the third electrical contact protruding along the third direction are increased or decreased in sequence. In this embodiment, the three electrical contacts can all be protruding in the third direction, and the protruding distances of the three electrical contacts are arranged in sequence, forming, for example Fig. 9 The structure shown. Fig. 9 As shown, the three electrical contacts 111 are spaced apart in the second direction, and the protruding lengths of the three electrical contacts increase from top to bottom in the third direction. It should be understood that Fig. 9 For exemplary purposes only, the protruding lengths of the three electrical contacts may also decrease sequentially from top to bottom in the third direction.

[0097] Thus, in the embodiment of the present application, by staggering the plurality of electrical contacts 111 in the third direction, it is possible to further prevent the electrical contacts 111 from being excessively scratched, and also to prevent problems such as short circuits or high-voltage breakdowns between different electrical contacts 111. Moreover, as mentioned above, it is also helpful to assist in positioning the conductive component 100 or the processing box 300, thereby further helping to save additional designs such as other positioning components.

[0098] It should be noted that the above embodiments can be used alone or in combination.

[0099] In an exemplary embodiment, at least two of the plurality of electrical contacts 111 may be spaced apart in the second direction, or may protrude at different distances in the third direction, for example. Fig. 9 shown.

[0100] In another exemplary embodiment, at least two of the multiple electrical contacts 111 may be spaced apart in the second direction, or may be staggered in the first direction but at a closer distance, for example, the projection positions of the multiple electrical contacts 111 in the second direction at least partially overlap.

[0101] In another exemplary embodiment, at least two of the multiple electrical contacts 111 can be spaced apart in the second direction and protrude different distances in the third direction, for example, the protruding length increases or decreases sequentially along the second direction. They can also be staggered in the first direction but at a closer distance, for example, the projection positions of the multiple electrical contacts 111 in the second direction at least partially overlap or overlap with the first area.

[0102] In addition, the conductive component 100 provided in the embodiment of the present application can be used to realize the electrical connection of multiple load components 310, and the embodiment of the present application has no particular limitation on the type and number of the multiple load components 310. Moreover, the type, model or value of the multiple load components 310 in the embodiment of the present application can be the same or different.

[0103] In an exemplary embodiment, in the conductive component 100, the plurality of electrical contacts 111 include a first electrical contact 111-1, a second electrical contact 111-2 and a third electrical contact 111-3, the load element 310 includes a first load element 310-1, a second load element 310-2 and a third load element 310-3, the first electrical contact 111-1 is electrically connected to the first load element 310-1, the second electrical contact 111-2 is electrically connected to the second load element 310-2, the third electrical contact 111-3 is electrically connected to the third load element 310-3, at least two of the first load element 310-1, the second load element 310-2 and the third load element 310-3 are different, and the second electrical contact 111-2 and the third electrical contact 111-3 are located on both sides of the first electrical contact 111-1 in the second direction.

[0104] Specifically, at least two of the first load element 310 - 1 , the second load element 310 - 2 , and the third load element 310 - 3 are different, including at least one of the types, models, and values ​​of the load elements.

[0105] For example, the first load member 310-1 may be a developing roller, and the second load member 310-2 and the third load member 310-3 may be a powder feeding roller and a powder discharge knife, respectively. Fig.10 As shown, the first electrical contact 111-1 can be located on the end surface of the protrusion 130, pass through the interior of the protrusion 130 and be electrically connected to the developing roller; the powder feeding roller and the powder discharge knife are electrically connected to the second electrical contact 111-2 and the third electrical contact 111-3 respectively, and the second electrical contact 111-2 and the third electrical contact 111-3 are located on both sides of the first electrical contact 111-1 in the second direction; in specific implementation, the second electrical contact 111-2 and the third electrical contact 111-3 can be located on both sides of the protrusion respectively, and the setting relationship with the protrusion 130 will be specifically described later.

[0106] For another example, the first load element 310 - 1 may be a developing roller, and the second load element 310 - 2 and the third load element 310 - 3 may be fixed resistors, but the resistance values ​​of the two may be different.

[0107] In addition, the embodiment of the present application has no particular restrictions on the connection relationship between the electrical contact 111 and the load 310. In actual scenarios, one electrical contact 111 can be used to electrically connect to one load 310, or to electrically connect to multiple loads 310. The electrical connection between the electrical contact 111 and the load 310 can be a direct contact connection between the two, or an indirect electrical connection through a bridging device (such as the moving mechanism 120 involved later).

[0108] In another exemplary embodiment, the conductive component 100 includes: a first electrical contact 111-1, a second electrical contact 111-2, and a third electrical contact 111-3, wherein the second electrical contact 111-2 is used to power three loads 310 through a voltage divider circuit, for example, the three loads 310 can be: a developing roller, a powder feeding roller, and a powder discharge knife. In actual implementation, the voltage divider circuit may include multiple branches, and the multiple branches are electrically connected to the second electrical contact 111-2 in parallel, and each branch is electrically connected to a load 310. In this embodiment, the second electrical contact 111-2 is electrically connected to the developing roller, the powder feeding roller, and the powder discharge knife through three branches in the voltage divider circuit. In the actual implementation scenario, the voltage divider circuit may also have other more devices or functions. Exemplarily, for any branch in the voltage divider circuit, one or more voltage adjustment modules, current adjustment modules, power adjustment modules, etc. may also be additionally provided. For example, considering that the working voltages of the developing roller, the powder feeding roller and the powder discharge knife are different, a voltage reduction module can be provided on the branch of the voltage dividing circuit to meet the voltage requirements of each load 310. For example, the absolute values ​​of the working voltages of the powder feeding roller, the developing roller and the powder discharge knife can be reduced in sequence. The first electrical contact 111-1 and the third electrical contact 111-3 in the conductive component 100 can be electrically connected to a fixed resistor or a variable resistor.

[0109] In another exemplary embodiment, the conductive component 100 includes: a first electrical contact 111-1, a second electrical contact 111-2, and a third electrical contact 111-3, wherein the second electrical contact 111-2 is electrically connected to two loads 310 through a voltage divider circuit. The voltage divider circuit includes two branches, one of which is electrically connected to the powder feeding roller, and the other is electrically connected to the developing roller or the powder discharge knife; and the first electrical contact 111-1 and the third electrical contact 111-3 in the conductive component 100 can be electrically connected to a fixed resistor or a variable resistor.

[0110] In another exemplary embodiment, the conductive component 100 includes: a first electrical contact 111-1, a second electrical contact 111-2, and a third electrical contact 111-3, wherein the first electrical contact 111-1 is electrically connected to two load members 310 through a voltage divider circuit, wherein one branch is electrically connected to a developing roller, and the other branch is electrically connected to a powder discharge knife. The second electrical contact 111-2 in the conductive component 100 is electrically connected to a powder feeding roller, and the third electrical contact 111-3 is electrically connected to a fixed resistor or a variable resistor.

[0111] It should be understood that the connection relationship between the electrical contacts 111 and the load 310 in the above embodiments is only exemplary. In actual scenarios, the connection relationship or position between the electrical contacts 111 and the load 310 may also be adjusted, which will not be described in detail.

[0112] In summary, in the embodiment of the present application, the multiple electrical contacts 111 on the conductive component 100 can be electrically connected to multiple load elements 310, and at least two load elements 310 have different functions. For example, one electrical contact 111 can be electrically connected to one of the powder feeding roller, the developing roller, and the powder discharge knife, and the other electrical contact 111 can also be electrically connected to the other two of the powder feeding roller, the developing roller, and the powder discharge knife, or electrically connected to other types of loads, such as fixed resistors or variable resistors, etc., and the custom design can be based on the actual scenario.

[0113] It should be particularly noted that the multiple electrical contacts 111 in the conductive component 100 are spaced apart in the second direction. The multiple electrical contacts 111 may be spaced apart in a fixed manner in the second direction, or at least one of the multiple electrical contacts 111 may be movably arranged.

[0114] Exemplarily, the movable setting may be achieved by a moving mechanism 120 .

[0115] In an exemplary embodiment, the conductive component 100 further includes a moving mechanism 120, which is used to move at least two of the plurality of conductive members 110 from a first position to a second position; at least two electrical contacts 111 located at the second position are spaced apart along the second direction.

[0116] In this embodiment, the moving mechanism 120 can be customized based on mechanical structure, elastic deformation, etc., so that the position of some of the multiple conductive members 110 changes, that is, it moves from the original first position to the second position. In addition, in the embodiment of the present application, after the position movement occurs based on the moving mechanism 120, the relationship between the multiple conductive members 110 can meet the characteristics of at least two electrical contacts 111 arranged at intervals along the second direction in the embodiment of the present application. The embodiment of the present application has no special restrictions on the position relationship between the multiple conductive members 110 before the position movement, that is, when some of the conductive members 110 are located in the first position, and it can be any customized form.

[0117] For example, Fig.10 and Fig.11 As shown, the conductive member 110 includes a first conductive member 110-1, a second conductive member 110-2 and a third conductive member 110-3, and the plurality of electrical contacts 111 include a first electrical contact 111-1, a second electrical contact 111-2 and a third electrical contact 111-3. The first electrical contact 111-1 is located on the first conductive member 110-1, the second electrical contact 111-2 is located on the second conductive member 110-2, and the third electrical contact 111-3 is located on the third conductive member 110-3, so that the first electrical contact 111-1 and / or the second electrical contact 111-2 and / or the third electrical contact 111-3 can be movably arranged on the main body of the conductive component 100 or the box body of the processing box 300.

[0118] Among them, the moving mechanism 120 is an elastic member, and the first conductive member 110-1 and / or the second conductive member 110-2 and / or the third conductive member 110-3 are arranged on the main body of the conductive component 100 or the box body of the processing box 300 through the elastic member. The first conductive member 110-1 and / or the second conductive member 110-2 and / or the third conductive member 110-3 move at least two of the multiple conductive members 110 from the first position to the second position through the elastic deformation of the elastic member, so that the first electrical contact 111-1, the second electrical contact 111-2 and the third electrical contact 111-3 are arranged at intervals along the second direction.

[0119] In this embodiment, at least one of the conductive members 110 can be connected to the main body of the conductive member 100 or the box body of the process box 300 by using the moving mechanism 120. In other words, in this embodiment, part of the conductive members 110 can also be fixedly arranged on the main body of the conductive member 100 or the box body of the process box 300.

[0120] Let’s take an example. Fig.10 and Fig.11 As shown, in the conductive component 100, the first conductive member 110-1 is fixedly arranged on the main body of the conductive component 100 or the box body of the processing box 300, and the second conductive member 110-2 and the third conductive member 110-3 are movably arranged on the main body of the conductive component 100 or the box body of the processing box 300 through the moving mechanism 120. The conductive component 100 can exist in two forms.

[0121] The first form is Fig.10 As shown, the second electrical contact 111 - 2 and the third electrical contact 111 - 3 are located at the first position, and in this case, the three electrical contacts 111 are arranged in a non-linear staggered manner in the first direction, the second direction, and the third direction.

[0122] The second form is Fig.11 As shown, the second electrical contact 111-2 and the third electrical contact 111-3 are located at the second position, and in this case, the three electrical contacts 111 meet the requirement of being arranged at intervals along the second direction. In addition, in this embodiment, as shown in FIG. Fig.11 As shown, the three electrical contacts 111 are arranged in a nonlinear front-to-back arrangement in the first direction. Thus, through the movement and adjustment of the moving mechanism 120, at least two electrical contacts 111 located at the second position are arranged at intervals along the second direction.

[0123] In a third form, at least two of the three electrical contacts 111 (eg, the second electrical contact 111 - 2 and the third electrical contact 111 - 3 ) are stacked along the third direction, so that the three electrical contacts 111 do not meet the requirement of being spaced apart along the second direction.

[0124] In actual implementation scenarios, such as Fig.10 The situation shown may be the unmounted state (or free state) of the conductive component 100. In this state, the positions of some electrical contacts 111 in the conductive component 100 may be freely set. The present application has no special requirements for this. Fig.10 As shown, they are misaligned in all directions, and they can also be aligned or partially aligned in all directions or any direction, which is not exhaustive. Fig.11 In the case shown in the figure, the conductive component 100 or the processing box 300 in which the conductive component 100 is installed in the image forming device 200 may be in a state; in this case, the plurality of electrical contacts 111 satisfy the characteristic of at least two being arranged at intervals along the second direction, so that the electrical contacts 111 of the conductive component 100 can be aligned with the power supply 210 in the image forming device 200 for electrical conduction. Specifically, when the conductive component 100 or the processing box 300 in which the conductive component 100 is installed in the image forming device 200, the conductive component 100 or the processing box 300 in which the conductive component 100 is installed is inserted into the conductive component 100 as shown in the figure. Figure 3 As shown in the cavity, as the conductive member 100 is continuously inserted in the installation direction during the installation process, the moving mechanism 120 in the conductive member 100 can be squeezed by the image forming device 200 side or by actively applying force, so that the electrical contact 111 moves relative to the main body of the conductive member 100, thereby moving the electrical contact 111 of the conductive member 110 from the first position to the second position, and finally forming the following Fig.11 Status shown.

[0125] In addition, in the embodiment of the present application, at least two electrical contacts 111 located at the second position are arranged at intervals along the second direction, but the present application has no special restrictions on the axial height of each conductive member 110, and the axial heights of the conductive members 110 where each electrical contact 111 located at the second position is located can be the same or different. For example, when the length of the conductive member 110 itself is different, when it is located at the second position, its axial height can be the same; when the length of the conductive member 110 itself is the same, when it is located at the second position, its axial height can be different.

[0126] The mobile mechanism 120 involved in the embodiment of the present application may have a variety of possible implementation methods, which may include but are not limited to: metal springs, metal sleeves, etc. For ease of understanding, please refer to Fig.12 , Fig.12 Specifically shows Fig.11 Possible implementations of the moving mechanism 120 involved in the conductive component 100 shown include: a metal spring 120-1 and a metal sleeve 120-2. Fig.12As shown, the second electrical contact 111-2 is connected to the second load 210-2 through the metal spring 120-1, the first electrical contact 111-1 is electrically connected with the metal axis of the first load 210-1, and the third electrical contact 111-3 is electrically connected with the third load 210-3 through the metal sleeve 120-2. Fig.10 and Fig.11 As shown, the metal spring 120 - 1 and the metal sleeve 120 - 2 can move the position of the electrical contact 111 , so that the conductive component 100 presents different positional relationships of the electrical contact 111 in the installed state and the non-installed state.

[0127] In addition, illustratively, the movable setting can also be achieved through the elastic conductive part 112.

[0128] In an exemplary embodiment, in the conductive component 100, at least two of the multiple conductive members 110 include an elastic conductive portion 112, and the elastic conductive portion 112 is used to contact the power supply member 210 to connect to the power supply. When the elastic conductive portion 112 contacts the power supply member 210, it is in an elastic deformation state, and the contact portion between the elastic conductive portion 112 and the power supply member 210 is an electrical contact 111; wherein, the electrical contacts 111 of the elastic conductive portions 112 of at least two conductive members 110 have different first projection lengths in the second direction.

[0129] That is, in this embodiment, the electrical contact 111 is a part of the elastic conductive part 112, that is, the elastic conductive part 112 has the ability to be electrically connected to a power source, a power supply device or a load, and the elastic conductive part 112 also has elastic deformation ability, and can present different elastic deformation states or non-deformation states accordingly. Therefore, based on the elastic deformation ability of the elastic conductive part 112, the electrical contact 111 can be placed in different positions.

[0130] The elastic conductive portion 112 may be specifically a spring or other elastic device, and the first projection length of the elastic conductive portion 112 in the second direction is related to the elastic deformation degree of the elastic conductive portion 112 .

[0131] Based on this, in the natural state (which can also be understood as the non-deformed state, or the conductive component 100 is not installed), the first projection lengths of the electrical contacts 111 of the elastic conductive parts 112 of at least two conductive members 110 in the second direction may be different. Conversely, in the elastic deformation state, the electrical contacts 111 of the conductive member 110 are in contact with the power supply member 210, and at least two of the electrical contacts 111 are spaced apart along the second direction.

[0132] In an exemplary embodiment, the conductive member 110 includes a first conductive member 110-1, a second conductive member 110-2 and a third conductive member 110-3, and the plurality of electrical contacts 111 include a first electrical contact 111-1, a second electrical contact 111-2 and a third electrical contact 111-3, the first electrical contact 111-1 is located on the first conductive member 110-1, the second electrical contact 111-2 is located on the second conductive member 110-2, and the third electrical contact 111-3 is located on the third conductive member 110-3, so that the first electrical contact 111-1 and / or the second electrical contact 111-2 and / or the third electrical contact 111-3 can be movably arranged on the main body of the conductive component 100 or the box body of the processing box 300. The first conductive element 110-1 and / or the second conductive element 110-2 and / or the third conductive element 110-3 are elastically deformed so that the first electrical contact 111-1, the second electrical contact 111-2 and the third electrical contact 111-3 are spaced apart along the second direction.

[0133] In summary, through the moving mechanism 120 or the elastic conductive part 112, the conductive component 100 can be installed in a state where at least two of the multiple electrical contacts 111 are spaced apart along the second direction, thereby helping to reduce poor power conduction and unstable power supply caused by scratches on the electrical contacts, and further avoiding abnormal imaging that may be caused by this.

[0134] In addition, it should be noted that the embodiment of the present application has no particular limitation on the actual structure of each conductive element 110 in the conductive component 100 .

[0135] In an exemplary embodiment, a plurality of conductive members 110 in the conductive member 100 may be arranged on the main body of the conductive member 100 or the box body 340 of the processing box 300, wherein the main body of the conductive member 100 or the box body 340 of the processing box 300 is provided with protrusions 130 arranged at intervals along the second direction, and the conductive members 110 are arranged on the protrusions 130, so that the electrical contacts 111 of the conductive members 110 can be electrically connected to the power supply or the power supply member. As mentioned above, in order to achieve installation matching with the image forming device 200, the position of the protrusion 130 matches the position of the guide groove in the image forming device 200. When the conductive member 100 or the processing box 300 provided with the conductive member 100 is installed in the image forming device 200, the protrusion 130 will extend into the guide groove and slide along the guide groove (i.e., the installation direction) until it is correctly installed. In the case of correct installation, the electrical contacts 111 in the conductive member 100 are respectively electrically connected to the power supply member 210 in the image forming device 200. In addition, as mentioned above, the protrusions 130 where the electrical contacts are located may be spaced a certain distance apart, and / or insulating materials may be provided to avoid problems such as short circuits or breakdowns.

[0136] In addition, the conductive member 110 involved in the embodiment of the present application can have a variety of specific forms, such as a conductive column (i.e., a columnar structure), a conductive sheet (i.e., a sheet structure) or any other form that can be used for electrical connection, and the embodiment of the present application has no special restrictions on this. In addition, the conductive member 110 can be formed by secondary injection molding of conductive plastic, or the conductive member 110 can be formed by using a conductive sheet covered on a plastic surface, which will not be described in detail.

[0137] In addition, the embodiment of the present application has no particular restrictions on the relative positional relationship between the conductive member 110 and the raised portion 130 where it is located. The conductive member 110 can be arranged at the top of the raised portion 130, and / or the conductive member 110 can also be arranged on the side of the raised portion 130. Further, the conductive member 110 can be specifically arranged on any side in the second direction.

[0138] In an exemplary embodiment, Fig.13 and Fig.14 As shown, the outer surface of the protrusion 130 includes an end surface and a side surface, wherein the first electrical contact 111-1 is disposed on the end surface of the protrusion 130, and the second electrical contact 111-2 and the third electrical contact 111-3 are disposed on the side surface of the protrusion 130. In specific implementation, the protrusion 130 may be provided with a first depression and a second depression on both side surfaces in the second direction, wherein the second electrical contact 111-2 (which may be electrically connected to the powder feeding roller) is at least partially disposed in the first depression, and the third electrical contact 111-3 is at least partially disposed in the second depression. In this way, when the conductive component 100 or the processing box 300 provided with the conductive component 100 is installed in the image forming device 200, the second electrical contact 111-2 can be electrically connected to the second load member 310-2, and the third electrical contact 111-3 can be electrically connected to the third load member 310-3.

[0139] Alternatively, in another exemplary embodiment, the multiple electrical contacts 111 in the conductive component 100 may also be arranged on the end surface of the protrusion 130. For example, the conductive component 100 may have multiple protrusions 130, so that the first electrical contact 111-1 is arranged on the end surface of the first protrusion 130-1, the second electrical contact 111-2 is arranged on the end surface of the second protrusion 130-2, and the third electrical contact 111-3 is arranged on the end surface of the third protrusion 130-3. In this embodiment, the positional relationship between the multiple protrusions 130 also satisfies the positional relationship of each electrical contact 111 in the embodiment of the present application. For example, the three protrusions 130 can be arranged in a "<" shape on the plane formed by the second direction and the first direction, and the three electrical contacts 111 can be respectively located on the end surfaces of the three protrusions 130, then the three electrical contacts 111 are also arranged in a "<" shape. Alternatively, on the plane formed by the second direction and the first direction, the three protrusions 130 may also be arranged in a "<" shape, and each electrical contact 111 may be arranged on the same side of each protrusion 130, etc. Alternatively, in another exemplary embodiment, the multiple electrical contacts 111 in the conductive component 100 may also be arranged on the side of the protrusion 130. No further details are given.

[0140] In summary, the conductive component 100 provided in the embodiment of the present application can be used to achieve installation matching between the processing box 300 and the image forming device 200, and at least two of the multiple electrical contacts 111 in the conductive component 100 are arranged at intervals along the second direction. This can reduce the number of electrical contact scratches generated in a single installation process during the installation of the conductive component 100 or the processing box 300 provided with the conductive component 100 along the installation direction, effectively reduce poor conductivity and unstable power supply caused by scratches on the electrical contacts 111, and thus avoid abnormal imaging conditions that may be caused by this.

[0141] The embodiment of the present application further provides a processing box 300. The processing box 300 includes:

[0142] Box body 340;

This application has no mandatory binding restrictions between the processing box 300 and the conductive member 110, and the two can exist independently or be used in combination.

[0151] Regarding the direction in the process box 300, the first direction is parallel to the installation direction of the process box 300 and also parallel to the extension direction of the guide groove 221 in the image forming device 200. In terms of specific implementation, the present application also specifically provides the following possible embodiments.

[0152] In an exemplary embodiment, the first direction is parallel to the direction of the line connecting the first projection position and the second projection position, the processing box 300 includes a positioning member 320, the first projection position is the projection position of the axis of the roller member 311 along the third direction, and the second projection position is the projection position of the positioning member 320 along the third direction. The conductive component 100 is generally also provided with a positioning member 320, and the positioning member 320 is generally in a convex or concave form, 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, and when the processing box 300 is inserted into the image forming device 200 along the installation direction, the positioning protrusion can be engaged with the positioning concave portion in the image forming device 200 to achieve the installation positioning function. In actual scenarios, the positioning member 320 can be set on the same side as the electrical contact 111, or it can be set on the opposite side of the processing box 300.

[0153] 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, 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, and 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.

In this way, it is not only conducive to the electrical connection with the power supply 210 or the power supply, but also convenient to realize the installation and positioning of the processing box 300. Therefore, in this embodiment, the positioning member can be further omitted, and the installation and positioning between the processing box 300 and the image forming device 200 can be realized directly through the conductive member 110. When the processing box 300 is installed, the protruding electrical contact 111 can no longer be inserted and moved forward in the installation direction, so as to achieve this installation and positioning effect.

[0157] Furthermore, the first electrical contact 111-1 is protruded in the third direction relative to the second electrical contact 111-2 and the third electrical contact 111-3; or, the protruding distances of the second electrical contact 111-2 and the first electrical contact 111-1 or the third electrical contact 111-3 along the third direction increase or decrease in sequence. The embodiment of the present application has no particular restrictions on the protruding distances of each electrical contact 111 in the third direction, and the relative positional relationship between them can be designed by oneself, which is not described in detail.

[0158] It should be noted that the above embodiments can be used alone or in combination.

[0159] In an exemplary embodiment, at least two of the plurality of electrical contacts 111 may be spaced apart in the second direction, or may protrude at different distances in the third direction, for example. Fig. 9 shown.

[0165] In a processing box 300 provided in an embodiment of the present application, there is no special restriction on the connection relationship between the electrical contact 111 and the load member 310. In actual scenarios, one electrical contact 111 can be used to electrically connect to one load member 310, or it can be used to electrically connect to multiple load members 310. The electrical connection between the electrical contact 111 and the load member 310 can be a direct contact connection between the two, or it can be an indirect electrical connection through a bridging device (such as the moving mechanism 120 involved later).

[0170] In addition, in the embodiment of the present application, the multiple electrical contacts 111 in the processing box 300 are arranged at intervals in the second direction. The multiple electrical contacts 111 can be arranged at intervals in a fixed form in the second direction, or at least one of the multiple electrical contacts 111 can be movably arranged.

[0171] Exemplarily, the movable setting can be realized by a moving mechanism 120. In an exemplary embodiment, the conductive component 100 further includes a moving mechanism 120, and the moving mechanism 120 is used to move at least two of the plurality of conductive members 110 from a first position to a second position; and at least two electrical contacts 111 located at the second position are spaced apart along the second direction.

[0172] At this time, if Fig.10 As shown, the conductive member 110 includes a first conductive member 110-1, a second conductive member 110-2 and a third conductive member 110-3, and a plurality of electrical contacts 111 include a first electrical contact 111-1, a second electrical contact 111-2 and a third electrical contact 111-3. The first electrical contact 111-1 is located on the first conductive member 110-1, the second electrical contact 111-2 is located on the second conductive member 110-2, and the third electrical contact 111-3 is located on the third conductive member 110-3, so that the first electrical contact 111-1 and / or the second electrical contact 111-2 and / or the third electrical contact 111-3 can be movably disposed on the main body of the conductive component 100 or the box body 340 of the processing box 300.

[0173] Among them, the moving mechanism 120 is an elastic member, and the first conductive member 110-1 and / or the second conductive member 110-2 and / or the third conductive member 110-3 are arranged on the main body of the conductive component or the box body 340 of the processing box 300 through the elastic member. The first conductive member 110-1 and / or the second conductive member 110-2 and / or the third conductive member 110-3 move at least two of the multiple conductive members 110 from the first position to the second position through the elastic deformation of the elastic member, so that the first electrical contact 111-1, the second electrical contact 111-2 and the third electrical contact 111-3 are arranged at intervals along the second direction.

[0174] 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. When the elastic conductive part 112 contacts the power supply member 210, it is in an elastic deformation state, and the contact part between the elastic conductive part 112 and the power supply member 210 is the electrical contact 111; wherein, the electrical contact 111 of the elastic conductive part 112 of at least two conductive members 110 has different first projection lengths in the second direction.

[0175] In one embodiment of this case, the conductive member 110 includes a first conductive member 110-1, a second conductive member 110-2 and a third conductive member 110-3, and a plurality of electrical contacts 111 include a first electrical contact 111-1, a second electrical contact 111-2 and a third electrical contact 111-3, the first electrical contact 111-1 is located on the first conductive member 110-1, the second electrical contact 111-2 is located on the second conductive member 110-2, and the third electrical contact 111-3 is located on the third conductive member 110-3, so that the first electrical contact 111-1 and / or the second electrical contact 111-2 and / or the third electrical contact 111-3 can be movably disposed on the main body of the conductive component or the box body 340 of the processing box 300.

[0176] The first conductive element 110-1 and / or the second conductive element 110-2 and / or the third conductive element 110-3 are elastically deformed so that the first electrical contact 111-1, the second electrical contact 111-2 and the third electrical contact 111-3 are spaced apart along the second direction.

[0177] In addition, in a preferred embodiment of the present application, the second direction is perpendicular to the third direction and the first direction.

[0178] In addition, in one embodiment of the present application, multiple electrical contacts 111 in the process box 300 are spaced apart by insulating materials. For example, the electrical contacts 111 or the raised portions 130 where the electrical contacts 111 are located may be spaced apart by a certain distance and / or insulating materials may be provided to avoid problems such as short circuit or breakdown.

[0179] In addition, in an embodiment of the present application, a protrusion 130 is provided on the box body 340 of the processing box 300 , and the electrical contacts 111 are all provided on the protrusion 130 .

[0180] In addition, in one embodiment of the present application, the process cartridge 300 includes a plurality of electrical contacts 111, the plurality of electrical contacts 111 include a first electrical contact 111-1, a second electrical contact 111-2, and a third electrical contact 111-3, the outer surface of the protrusion 130 includes an end surface and a side surface, and the first electrical contact 111-1 is disposed on the end surface of the protrusion 130. In a further possible embodiment, the second electrical contact 111-2 and the third electrical contact 111-3 are disposed on the side surface of the protrusion 130.

[0181] It is understandable that, depending on the type of the image forming apparatus 200, the process cartridge 300 also has different specifications:

[0182] When the image forming device 200 has only a black-and-white printing function, only one process cartridge 300 is usually required to be installed in one image forming device 200;

[0183] When the image forming device 200 has a color printing function, there can be multiple processing boxes 300, and different processing boxes 300 are used to print different colors. For example, four processing boxes 300 are used for cyan (Cyan), magenta (Magenta), yellow (Yellow), and black (Key) printing respectively. The four processing boxes 300 can perform pure color printing separately in one printing job, or print various different colors by superimposing and mixing the above four colors. At this time, at least one processing box 300 can be provided with the above conductive component 100. Of course, the processing box 300 may also be used for printing other colors, and is not limited to the above colors.

[0184] For any parts not described in detail, please refer to the previous text and I will not repeat them here.

[0185] The present application also provides an image forming device 200. Figure 3 and Figure 5 As shown, the image forming device 200 includes:

[0186] The body 240 of the image forming device 200 includes an inner plate 220 , and a guide groove 221 is provided on the inner plate 220 ;

[0187] A plurality of power supply members 210;

[0188] Wherein, at least two of the plurality of power supply members 210 are spaced apart along the second direction;

[0189] The first direction is parallel to the extending direction of the guide groove 221, the second direction intersects with the first direction, and the second direction and the first direction are respectively parallel to the plane where the inner plate 220 is located;

[0190] The guide groove 221 is used to guide the installation direction of the conductive component 100 or the processing box 300 .

[0191] In the embodiment of the present application, the first direction is parallel to the extension direction of the guide groove 221 and also parallel to the installation direction of the process cartridge 300. The possible implementation methods thereof can be referred to above and will not be described in detail. The second direction and the first direction are respectively parallel to the plane where the inner plate 220 is located. In other words, the plane formed by the second direction and the first direction is parallel to the plane where the inner plate 220 is located.

[0192] In the embodiment of the present application, the process box 300 and the conductive component 100 are used to be adapted and installed with the image forming device 200. Based on this, similar to the multiple electrical contacts 111 mentioned above, at least two of the multiple power supply members 210 are also spaced apart along the second direction. The spacing setting method can be spaced apart by a certain physical distance or by spacing through insulating materials.

[0193] 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 second direction at least partially overlap; or, the projection positions of at least two of the multiple power supply components 210 along the second direction at least partially overlap with the first area.

[0194] In addition, in another possible embodiment of the present application, the distances of the multiple power supply members 210 in the image forming device 200 protruding in the third direction may be different. The third direction intersects the first direction and the second direction. Preferably, the third direction may be perpendicular to the first direction and the second direction respectively. Moreover, in the installation scenario of the processing box 300, the third direction may also be parallel to the axial direction of the roller member 311. No further description is given.

[0195] Furthermore, in the specific implementation of the embodiment of the present application, the multiple power supply members 210 may include: a first power supply member, a second power supply member, and a third power supply member. In one implementation, the first power supply member may be recessed in the third direction relative to the second power supply member and the third power supply member; 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 third direction relative to the second electrical contact 111-2 and the third electrical contact 111-3. Alternatively, in another implementation, the recessed distance of the second power supply member and the first power supply member or the third power supply member along the third direction increases or decreases in sequence; accordingly, in order to adapt to the design, the protruding distance of 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 along the third direction increases or decreases in sequence.

[0196] For the image forming device 200, the positions of the multiple power supply members 210 in the image forming device 200 are generally fixed. Based on the above design, when the conductive member 100 or the processing box 300 provided with the conductive member 100 is installed in the image forming device 200, unnecessary scratching of the electric contacts can be avoided. In this way, the embodiment of the present application can effectively reduce the poor conductivity and unstable power supply caused by the scratching of the electric contacts by reducing the number of contacts and scratches between the electric contacts and the power supply members during a single installation of the processing box, thereby avoiding the abnormal imaging caused by the scratching of the electric contacts and improving the stability of power supply.
