Description

Technical Field

[0001] This application relates to the field of image forming technology, and in particular to a conductive component, a processing box, and an image forming apparatus. Background Technology

[0002] In related technologies, image forming apparatuses typically employ a single drum unit paired with multiple developing units to form color images. To save space, the developing units can be made flat, with the high-voltage conductive contacts on the developing units arranged sequentially in the mounting direction of the developing units. Please refer to [reference needed]. Figure 1 , Figure 1 This is a schematic diagram of the structure of a developing cartridge in related technologies, such as... Figure 1 As shown, three high-voltage conductive contacts 1-3 are sequentially arranged on the side of the developer cartridge along its installation direction (denoted as D1). When the developer cartridge moves along the installation direction, such as when it is inserted into or removed from the printer, the high-voltage conductive contacts on the developer cartridge side will rub against the high-voltage power supply contacts on the printer side, causing contact wear. This can lead to poor conductivity, unstable power supply, and ultimately, abnormal printing. Summary of the Invention

[0061] The following description provides numerous specific details to offer a more thorough understanding of this application. However, it will be apparent to those skilled in the art that this application can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described to avoid confusion with this application.

[0062] This application provides a conductive component.

[0063] Please refer to Figure 2 , Figure 2 This is a schematic diagram of the architecture of a conductive component provided in an embodiment of this disclosure. Figure 2 As shown, the conductive component 100 includes a plurality of conductive elements 110; wherein, the conductive element 110 includes electrical contacts 111, in other words, the conductive element 110 can be electrically connected to other conductive objects through the electrical contacts 111. For example, the conductive element 110 can be electrically connected to a power supply device (e.g., a power supply element 210 or a power source in the image forming apparatus 200) through the electrical contacts 111, and / or can also be electrically connected to a powered device (e.g., a load element in the processing cartridge 300, or a load element in the conductive component 100) through the electrical contacts 111, which will not be elaborated further. Specifically, the electrical contacts 111 are the portions of the conductive element 110 that contact and are electrically connected to the power supply device.

[0064] It should be understood that Figure 2 Three conductive elements 110 are shown: a first conductive element 110-1, a second conductive element 110-2, and a third conductive element 110-3; correspondingly, Figure 2 Three electrical contacts 111 are also shown: first electrical contact 111-1, second electrical contact 111-2, and third electrical contact 111-3. It should be understood that... Figure 2This is merely an example; in real-world scenarios, there may be more or fewer conductive elements 110, and this disclosure does not impose any particular limitation on this. For ease of explanation, the following description will still use three conductive elements 110 as an example.

[0065] In this embodiment, at least two of the plurality of electrical contacts 111 are spaced apart along a second direction (denoted as D2). The second direction intersects with the first direction (denoted as D1) and a third direction (denoted as D3). Possibly, with D1 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 practical scenarios, the second direction can be determined by the first direction and the third direction, which are related to the application scenario of the conductive component 100.

[0066] For example, the conductive component 100 described above can be applied in the installation and matching scenario of the processing cartridge 300 and the image forming apparatus 200. The image forming apparatus 200 may include, but is not limited to, a printing device (or printer), while the processing cartridge 300 can be any cartridge detachably installed in the image forming apparatus 200, which can be electrically connected to the image forming apparatus 200 via the conductive component 100. For example, the processing cartridge 300 involved in the embodiments of this application may include, but is not limited to, a developing cartridge (or developing assembly), a drum cartridge, etc., without exhaustive list. In this embodiment, the conductive component 100 can be used to achieve an electrical connection between the load component 310 in the processing cartridge 300 and the power supply component 210 in the image forming apparatus 200.

[0067] The load element 310 in the processing cartridge 300 can be of various types, including but not limited to at least one of the following: roller 311, powder delivery blade, fixed resistor, and variable resistor. Specifically, at least one roller 311 includes a developing roller, and may also include, but is not limited to, a powder delivery roller, a photosensitive drum, etc., without exhaustive list. In one possible embodiment, roller 311 includes a developing roller and / or a powder delivery roller and / or a photosensitive drum.

[0068] Specifically, such as Figure 4As shown, the image forming apparatus 200 has an internal mounting cavity. The imaging assembly 230 and the processing cartridge 300 (or developing assembly) need to be installed into the mounting cavity respectively, with the imaging assembly 230 installed first, followed by the developing assembly. The imaging assembly 230 is equipped with a photosensitive drum (OPC), and the developing assembly is equipped with a developing roller. When the imaging assembly 230 and the developing assembly are installed in the mounting cavity, the developing roller and the photosensitive drum need to be positioned opposite each other, and they may or may not be in contact. During printing or other image forming processes, the toner on the developing roller can be adsorbed onto the surface of the photosensitive drum. In addition to the developing roller, the developing assembly also has a toner feeding roller and a toner dispensing blade. The housing of the developing assembly also has a receiving cavity for holding toner. The function of the toner feeding roller is to transport the toner in the receiving cavity to the developing roller. The developing roller is charged and can adsorb toner. The toner dispensing blade 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 toner is evenly adsorbed in all areas of the surface of the photosensitive drum. In one application scenario, the load components 310 need to operate with electricity. Therefore, the electrical connection between each load component 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 this application embodiment can be disposed on the processing cartridge 300 or the image forming apparatus 200, with the processing cartridge 300 detachably mounted to the body of the image forming apparatus 200. The conductive component 100 is used to achieve electrical connection between the power supply component 210 of the image forming apparatus 200 and the load component 310 of the processing cartridge 300, at least one load component 310 including a roller 311. Thus, the electrical contacts 111 in the conductive component 110 can be used to contact the power supply component 210 to access power. Furthermore, in this application embodiment, at least two of the plurality of electrical contacts 111 are spaced apart along a second direction, wherein the second direction intersects with both a third direction and a first direction, the mounting direction of the processing cartridge 300 is the first direction, and the third direction is parallel to the axial direction of the roller 311.

[0070] It should be noted that the conductive component 100 can be an independent device separate from the processing box 300 and the image forming apparatus 200; or, the conductive component 100 can also be disposed on the processing box 300 as part of the processing box 300, for realizing 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 disposed on the image forming apparatus 200 as part of the image forming apparatus 200, for realizing the mounting alignment with the processing box 300.

[0071] When the processing cartridge 300 is installed in the image forming apparatus 200 and specifically used for developing capability, one end of the roller 311 can be a conductive element 110, and the conductive element 110 has an electrical contact 111. Alternatively, one end of the roller 311 can be electrically connected to the electrical contact 111 through a connecting component. Thus, when the processing cartridge 300 is installed through the conductive component 100, the roller 311 can be electrically connected to the power supply through the electrical contact 111 and the power supply component 210, thereby powering on and starting up. In practical scenarios, the roller 311 (especially the developing roller) generally intersects with the plane where the electrical contact 111 is located and is fixedly installed; preferably, for ease of electrical connection, the roller 311 can be perpendicular to the plane where the electrical contact 111 is located. In this embodiment, a third direction is determined based on the axial direction of the roller 311, using the fixedly installed roller 311 as a reference. That is, the third direction is parallel to the axial direction of the roller 311. Preferably, in one embodiment, the third direction is parallel to the axial direction of the developing roller.

[0072] Furthermore, in this embodiment, 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 apparatus 200, the first direction is related to the architecture of the image forming apparatus 200. For different image forming apparatuses 200, the first direction is also different to achieve installation adaptation between the two.

[0073] Combination Figures 3-5 For example. Figure 3 As shown, the image forming apparatus 200 includes an inner side plate 220, on which a guide groove 221 is provided. The guide groove 221 guides the installation direction of the processing cartridge 300. Specifically, the conductive member 110 can generally protrude. When installing the processing cartridge 300, the conductive member 110 can extend into the guide groove 221 and slide along the guide groove 221. In this way, the processing cartridge 300 can be detachably installed into the image forming apparatus 200 by a pull-in method. The structure after installation can be referred to Figure 4 As shown. And, as... Figure 3 and Figure 5 As shown, the image forming apparatus 200 also includes a plurality of power supply components 210, which are also spaced apart along the second direction. In other words, the positions of the electrical contacts 111 can match those of the power supply components 210, so that after installation and matching, the electrical contacts 111 can contact and electrically connect with the power supply components 210. In this embodiment, the first direction can also be specifically understood as the insertion / removal direction of the processing cartridge 300, or as the extension direction of the guide groove 221 in the image forming apparatus 200. The guide groove 221 is disposed on the inner side plate 220 and is used to guide the installation direction of the processing cartridge 300. In other words, the installation direction of the processing cartridge 300 is parallel to the extension direction of the guide groove 221.

[0074] Thus, at least two of the plurality of electrical contacts 111 are spaced apart along a second direction, which intersects the mounting direction of the processing box (i.e., the first direction) and the axial direction of the roller (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, such as... Figure 2 As shown. Therefore, when the processing cartridge 300 is inserted and removed from the installation direction to install it into the image forming apparatus 200, since at least two electrical contacts 111 are not arranged sequentially in the installation direction of the processing cartridge 300, the number of contacts and scratches between the electrical contacts 111 and the power supply component 210 during a single installation of the processing cartridge 300 can be reduced. This effectively reduces situations such as poor power conductivity and unstable power supply caused by scratching of the electrical contacts 111, and thus avoids possible imaging abnormalities. In summary, the technical solution provided by the embodiments of this application can reduce the number of electrical contact scratches and improve power supply stability.

[0075] To further illustrate the possible forms of the first direction, the following example, with the conductive component 100 disposed on the processing box 300, will be used to illustrate the specific structure of the processing box 300.

[0076] In one exemplary embodiment, the first direction is parallel to the line connecting the first and second projection positions. The processing box 300 includes a positioning member 320. The first projection position is the projection position of the axis of the roller 311 along a third direction, and the second projection position is the projection position of the positioning member 320 along a third direction. The conductive component 100 is generally also provided with a positioning member 320, which is generally in the form of a protrusion or a recess, used to position the processing box 300 during installation. For example, the positioning member 320 can specifically be a positioning protrusion. When the processing box 300 is inserted into the image forming apparatus 200 along the installation direction, the positioning protrusion can partially engage with the positioning recess in the image forming apparatus 200, such as the guide groove 221 mentioned above, 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 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, with a first direction parallel to the sequential arrangement direction of the plurality of functional electrical contacts 331. The information processing device 330 can specifically be any device or component with information processing capabilities within the processing box 300; for example, the information processing device 330 may include, but is not limited to, a chip. The information processing device 330 can transmit information, instructions, or one or more other data to 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 (GND). The four functional electrical contacts 331 are respectively used to contact four electrical contacts on the image forming device, such as conductive springs, styluses, and electrical contacts. The four functional electrical contacts 331 are arranged sequentially at intervals in the same direction, and the first direction is parallel to the direction in which the four functional electrical contacts 331 are arranged sequentially.

[0078] It is understandable that information processing devices have multiple conductive terminals, which can be square, round, or other shapes, specifically as follows: Figure 6 As shown, the functional electrical contact 331 is a portion of the conductive terminal used to contact the electrical contact portion of the image forming apparatus.

[0079] The information processing device 330 may have other types of terminals that do not directly contact the electrical contacts of the image forming apparatus. These terminals may be arranged in the same direction as the conductive terminals, or they may not be arranged in the same direction as the conductive terminals.

[0080] Of course, depending on the circumstances, the number of functional electrical contacts 331 on the information processing device 330 may also be other, such as more than four or less than four.

[0081] In addition, the processing box 300 generally has multiple outer wall surfaces, and the information processing device 330 can be disposed at the 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, which includes functional electrical contacts 331. A first direction is parallel to the line connecting the first and third projection positions. The first projection position is the projection position of the axis of the roller 311 along a third direction, and the third projection position is the projection position of the functional electrical contacts 331 along a third direction. The processing box 300 has a first end face and a second end face located at both ends of the roller. At least one functional electrical contact 331 is located on either the first or second end face, and the functional electrical contact 331 located on the first or second end face projects along a third direction to form the third projection position.

[0083] Specifically, the information processing device 330 may have four functional electrical contacts 331, namely a power contact (VCC), a data signal contact (SDA), a clock signal contact (CLK), and a ground contact (GND). The four functional electrical contacts 331 are respectively used to contact four electrical contacts on the image forming apparatus, such as conductive springs, styluses, and electrical contacts. At least one of the four functional electrical contacts 331 is located on a first end face or a second end face.

[0084] Similarly, the information processing device 330 may have other types of terminals that do not directly contact the electrical contacts of the image forming apparatus, and such terminals cannot be used to form a third projection position.

[0085] It should be noted that when it is necessary to determine the direction or length by projecting different positions along the same projection direction, the projected positions should be located in the same projection plane perpendicular to the projection direction. Similarly, when it is necessary to determine whether different projections along the same projection direction have overlapping positions or specific positional relationships, the projections should also be located in the same projection plane perpendicular to the projection direction.

[0086] In a preferred embodiment of this 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. Alternatively, in a preferred embodiment, insulating material can be provided to prevent short circuits or breakdowns.

[0087] Thus, in this embodiment, multiple electrical contacts 111 are spaced apart in the second direction, which intersects with the first direction. Therefore, on the projection plane of the first direction, the projected positions of the multiple electrical contacts 111 may not overlap completely, or there may be partial overlap, such as the case where multiple electrical contacts are located on the end face and side face of a protrusion 130, as described later. Thus, during the installation of the conductive component 100 or the processing box 300 equipped with the conductive component 100, when the electrical contacts 111 are installed along the first direction, they will not contact the multiple power supply components 210 provided in the image forming apparatus 200. This avoids unnecessary scratching contact during a single installation, reduces potential power supply instability due to frequent scratching, and improves power supply stability.

[0088] Furthermore, in this embodiment, the projected positions of multiple electrical contacts 111 in the conductive component 100 in the second direction can be relatively close, so that the three-dimensional structural relationship between the multiple electrical contacts 111 can present an effect of longitudinal arrangement in the second direction.

[0089] Specifically, in one possible embodiment, at least two of the projected positions 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, at least two of the plurality of electrical contacts 111 have projection positions along the second direction that at least partially overlap with the first region. The first region is the projection area of ​​the outer contour of the roller shaft of the roller 311 in the second direction. Specifically, when the processing cartridge 300 is a developing assembly, the developing roller, as the most important developing device in the developing assembly, has a relatively fixed position within the developing assembly, which can be used to design the spatial positions of each electrical contact 111; in other words, in this embodiment, the roller 311 can specifically be a developing roller. In this case, refer to... Figure 8 ,like Figure 8 As shown, viewed from the axial direction (third direction, denoted as D3) of the developing roller, the developing roller can be composed of an inner roller shaft and an outer protective structure. The projection of the outer contour of the developing roller shaft in the second direction is the interval [A,B] between point A and point B in the first direction, and is related to the protrusion length of the developing roller in the second direction. In this embodiment, at least two of the multiple electrical contacts 111 have projection positions along the second direction that at least partially overlap with the interval [A,B]. This allows the multiple electrical contacts 111 to be relatively close together in the first direction and spaced apart in the second direction, such as... Figure 8 As shown, the multiple electrical contacts 111 present an effect of being arranged longitudinally in the second direction.

[0091] Furthermore, in this embodiment, at least one of the plurality of electrical contacts 111 can be protruding, i.e., protruding from its plane. This facilitates electrical connection with the power supply component 210 or the power source, and also makes it easier to install and position the processing box 300. Thus, in this embodiment, the positioning component can be further omitted, and the installation and locking between the processing box 300 and the image forming apparatus 200 can be achieved directly through the conductive component 110. When the processing box 300 is installed, the protruding electrical contacts 111 can no longer be inserted forward in the installation direction, thus achieving this installation and positioning effect.

[0092] In one exemplary embodiment, the conductive component 100 includes a plurality of electrical contacts 111, including 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 and the second electrical contact 111-2 or the third electrical contact 111-3 protrude at different distances in the third direction.

[0093] For any electrical contact 111, its upward protrusion distance in a third direction refers to the distance the electrical contact protrudes beyond the plane of the conductive component 100 on which it is located. This protrusion distance can be determined with the plane of the conductive component 100 as a reference, or it can be determined by using any point on the conductive component 100 that is further away from the electrical contact in a third direction as a reference, and determining the length of each electrical contact relative to that reference point. In practical scenarios, this solution can be achieved if at least one of the multiple electrical contacts 111 can be protruding. In addition, in other possible embodiments, there may be electrical contacts 111 that are flush with the plane of the conductive component 100 on which they are located, or there may be electrical contacts that are recessed relative to the plane of the conductive component 100 on which they are located.

[0094] In this embodiment of the application, there are no particular restrictions on the distance value of each of the above-mentioned electrical contacts 111 protruding upwards in a third direction, the arrangement relationship, etc.

[0095] In a preferred embodiment, the first electrical contact 111-1 in the conductive component 100 protrudes upward relative to the second electrical contact 111-2 and the third electrical contact 111-3. In this embodiment, at least one of the three electrical contacts 111 in the conductive component 100 has a longer protrusion length; the other two contacts may also protrude, but with a shorter protrusion length. The protrusion lengths of the second electrical contact 111-2 and the third electrical contact 111-3 may be the same or different; alternatively, the second electrical contact 111-2 may be flush with or recessed from its plane, and the third electrical contact 111-3 may also be flush with or recessed from its plane. Further details are omitted. This application embodiment does not impose any particular limitation on the position of the first electrical contact 111-1. For example, the first electrical contact 111-1 can be located at the first, second, or third position from top to bottom in the third direction, without any particular restriction.

[0096] Alternatively, in another preferred embodiment, the distance between the second electrical contact and the first or third electrical contact protruding along a third direction increases or decreases sequentially. In this embodiment, all three electrical contacts can protrude in the third direction, and the protrusion distances of the three electrical contacts are arranged sequentially to form, for example... Figure 9 The structure shown. (As illustrated) Figure 9 As shown, three electrical contacts 111 are spaced apart in the second direction, and the protrusion length of the three electrical contacts increases sequentially from top to bottom in the third direction. It should be understood that... Figure 9 For illustrative purposes only, the protrusion length of the three electrical contacts may also decrease sequentially from top to bottom in the third direction.

[0097] Thus, in this embodiment of the application, by designing multiple electrical contacts 111 to be staggered in the third direction, it is possible to further prevent the electrical contacts 111 from being scratched too much, and at the same time, it is possible to prevent short circuits or high voltage breakdowns between different electrical contacts 111. Furthermore, as mentioned above, it is also beneficial to assist in the positioning of the conductive component 100 or the processing box 300, which is more conducive to saving additional design such as other positioning components.

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

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

[0100] In another exemplary embodiment, at least two of the plurality of electrical contacts 111 may be spaced apart in the second direction or staggered in the first direction but close to each other, for example, the projected positions of the plurality of electrical contacts 111 in the second direction at least partially overlap.

[0101] In another exemplary embodiment, at least two of the plurality of electrical contacts 111 may be spaced apart in the second direction and protrude upward at different distances in the third direction. For example, the protrusion length may increase or decrease sequentially along the second direction. Alternatively, they may be staggered in the first direction but closer together. For example, the projection positions of the plurality of electrical contacts 111 in the second direction may at least partially overlap or overlap with the first region.

[0102] Furthermore, the conductive component 100 provided in this application embodiment can be used to realize electrical connection to multiple load components 310, and this application embodiment does not have any particular limitation on the type and number of multiple load components 310. Moreover, the types, models, or values ​​of the multiple load components 310 can be the same or different in this application embodiment.

[0103] In one exemplary embodiment, the conductive component 100 includes a plurality of electrical contacts 111, including a first electrical contact 111-1, a second electrical contact 111-2, and a third electrical contact 111-3. The load component 310 includes a first load component 310-1, a second load component 310-2, and a third load component 310-3. The first electrical contact 111-1 is electrically connected to the first load component 310-1, the second electrical contact 111-2 is electrically connected to the second load component 310-2, and the third electrical contact 111-3 is electrically connected to the third load component 310-3. At least two of the first load component 310-1, the second load component 310-2, and the third load component 310-3 are different. 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 a second direction.

[0104] Specifically, at least two of the three load components 310-1, 310-2, and 310-3 are different, including at least one difference in the type, model, or value of the load components.

[0105] For example, the first load element 310-1 can be a developing roller, and the second load element 310-2 and the third load element 310-3 can be a powder feeding roller and a powder exiting blade, respectively. In this embodiment, as... Figure 10 As shown, the first electrical contact 111-1 can be located on the end face of the protrusion 130, and passes through the interior of the protrusion 130 and is electrically connected to the developing roller; while the powder feeding roller and the powder discharging blade are electrically connected to the second electrical contact 111-2 and the third electrical contact 111-3 respectively. 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, and the arrangement relationship with the protrusion 130 will be explained in detail later.

[0106] For example, the first load element 310-1 can be a developing roller, and the second load element 310-2 and the third load element 310-3 can be fixed resistors, but their resistance values ​​can be different. This is not an exhaustive list.

[0107] Furthermore, this application embodiment does not impose any particular restrictions on the connection relationship between the electrical contact 111 and the load element 310. In practical scenarios, one electrical contact 111 can be used to electrically connect to one load element 310, or it can be used to electrically connect to multiple load elements 310. The electrical connection between the electrical contact 111 and the load element 310 can be a direct contact connection, or an indirect electrical connection can be made through a bridging device (such as the moving mechanism 120 mentioned 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. The second electrical contact 111-2 supplies power to three load components 310 via a voltage divider circuit. For example, the three load components 310 can be a developing roller, a powder feeding roller, and a powder exiting blade. In actual implementation, the voltage divider circuit can include multiple branches, which are electrically connected to the second electrical contact 111-2 in parallel. Each branch is electrically connected to one load component 310. In this embodiment, the second electrical contact 111-2 is electrically connected to the developing roller, the powder feeding roller, and the powder exiting blade via the three branches in the voltage divider circuit. In practical implementations, the voltage divider circuit can also have other components or functions. For example, for any branch in the voltage divider circuit, one or more additional components such as a voltage adjustment module, a current adjustment module, and a power adjustment module can be provided. For example, considering the different operating voltages of the developing roller, the powder feeding roller, and the powder exiting blade, a step-down module can be installed on a branch of the voltage divider circuit to meet the voltage requirements of each load component 310. For example, the absolute values ​​of the operating voltages of the powder feeding roller, the developing roller, and the powder exiting blade can be decreased sequentially. 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. The second electrical contact 111-2 is electrically connected to two load components 310 via 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 branch is electrically connected to the developing roller or the powder exiting blade. The first electrical contact 111-1 and the third electrical contact 111-3 of 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. The first electrical contact 111-1 is electrically connected to two load components 310 via a voltage divider circuit, one branch of which is electrically connected to the developing roller, and the other branch is electrically connected to the powder delivery blade. The second electrical contact 111-2 of the conductive component 100 is electrically connected to the powder delivery 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 contact 111 and the load element 310 in the above embodiments is only exemplary. In actual scenarios, the connection relationship or position of each electrical contact 111 and the load element 310 can also be adjusted, which will not be elaborated here.

[0112] In summary, in this embodiment, the multiple electrical contacts 111 on the conductive component 100 can be electrically connected to multiple load components 310, and at least two load components 310 have different functions. For example, one electrical contact 111 can be electrically connected to one of the powder feeding roller, developing roller, and powder discharging blade, and another electrical contact 111 can be electrically connected to the other two of the powder feeding roller, developing roller, and powder discharging blade, or electrically connected to other types of loads, such as fixed resistors or variable resistors, etc., which can be customized based on the actual scenario.

[0113] It should be noted that the plurality of electrical contacts 111 in the conductive component 100 are spaced apart in the second direction. This can be either that the plurality of electrical contacts 111 are spaced apart in a fixed manner in the second direction, or that at least one of the plurality of electrical contacts 111 is movable.

[0114] For example, the movable settings can be implemented via the moving mechanism 120.

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

[0116] In this embodiment, the moving mechanism 120 can be custom-designed based on mechanical structure, elastic deformation, etc., so that the positions of some of the multiple conductive elements 110 change, that is, move from the original first position to the second position. Furthermore, in this embodiment, after the positional movement based on the moving mechanism 120, the relationship between the multiple conductive elements 110 satisfies the characteristic of at least two electrical contacts 111 being spaced apart along a second direction in this embodiment. This embodiment does not particularly limit the positional relationship between the multiple conductive elements 110 before the positional movement, i.e., when some conductive elements 110 are in the first position; it can be any custom configuration.

[0117] For example, such as Figure 10 and Figure 11 As shown, the conductive element 110 includes a first conductive element 110-1, a second conductive element 110-2, and a third conductive element 110-3. 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 element 110-1, the second electrical contact 111-2 is located on the second conductive element 110-2, and the third electrical contact 111-3 is located on the third conductive element 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 element 100 or the housing of the processing box 300.

[0118] The moving mechanism 120 is an elastic element. The first conductive element 110-1 and / or the second conductive element 110-2 and / or the third conductive element 110-3 are disposed on the main body of the conductive component 100 or the box body of the processing box 300 through the elastic element. The first conductive element 110-1 and / or the second conductive element 110-2 and / or the third conductive element 110-3 cause at least two of the multiple conductive elements 110 to move from the first position to the second position through the elastic deformation of the elastic element, 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.

[0119] In this embodiment, at least one of the conductive elements 110 can be connected to the main body of the conductive component 100 or the housing of the processing box 300 using a moving mechanism 120. In other words, in this embodiment, some of the conductive elements 110 can also be fixedly disposed on the main body of the conductive component 100 or the housing of the processing box 300.

[0120] For example. Figure 10 and Figure 11 As shown, in the conductive component 100, the first conductive element 110-1 is fixedly disposed on the main body of the conductive component 100 or the housing of the processing box 300, while the second conductive element 110-2 and the third conductive element 110-3 are movably disposed on the main body of the conductive component 100 or the housing of the processing box 300 via the moving mechanism 120. The conductive component 100 can exist in two forms.

[0121] The first form is as follows Figure 10 As shown, the second electrical contact 111-2 and the third electrical contact 111-3 are located in the first position, and in this case, the three electrical contacts 111 exhibit a non-linear staggered arrangement in the first direction, the second direction, and the third direction.

[0122] The second form is as follows Figure 11 As shown, the second electrical contact 111-2 and the third electrical contact 111-3 are located in the second position, and in this case, the three electrical contacts 111 satisfy the requirement of being spaced apart along the second direction. Furthermore, in this embodiment, as... Figure 11 As shown, the three electrical contacts 111 are arranged in a non-linear, front-to-back configuration in the first direction. Thus, by adjusting the movement of the moving mechanism 120, at least two electrical contacts 111 located in the second position are spaced apart along the second direction.

[0123] In the third configuration, at least two of the three electrical contacts 111 (e.g., the second electrical contact 111-2 and the third electrical contact 111-3) are stacked along a third direction, such 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 Figure 10 The situation shown represents the uninstalled state (or free state) of the conductive component 100. In this state, the positions of some of the electrical contacts 111 in the conductive component 100 can be freely set. This application has no special requirements for this, and it can be as follows: Figure 10 The diagram shows misalignment in all directions, but alignment or partial alignment in all or any direction is also possible; the possibilities are not exhaustive. However, as shown... Figure 11 The situation described represents the state after the conductive component 100 or the processing cartridge 300 containing the conductive component 100 is installed into the image forming apparatus 200. In this case, the plurality of electrical contacts 111 satisfy the characteristic that at least two are spaced apart along the second direction, allowing the electrical contacts 111 of the conductive component 100 to be aligned and conductive with the power supply component 210 in the image forming apparatus 200. Specifically, when installing the conductive component 100 or the processing cartridge 300 containing the conductive component 100 into the image forming apparatus 200, the conductive component 100 or the processing cartridge 300 containing the conductive component 100 is inserted into... Figure 3 In the cavity shown, as the component is continuously inserted in the installation direction during the installation process, the moving mechanism 120 in the conductive component 100 can be squeezed by the image forming apparatus 200 or by actively applying force, thereby causing the electrical contact 111 to move relative to the main body of the conductive component 100. This moves the electrical contact 111 of the conductive component 110 from a first position to a second position, ultimately forming the cavity as shown. Figure 11 The state shown.

[0125] Furthermore, in this embodiment, at least two electrical contacts 111 located in the second position are spaced apart along the second direction. However, this application does not impose any particular limitation on the axial height of each conductive element 110. The axial heights of the conductive elements 110 where each electrical contact 111 is located in the second position can be the same or different. For example, when the lengths of the conductive elements 110 are different, their axial heights can be the same when located in the second position; when the lengths of the conductive elements 110 are the same, their axial heights can be different when located in the second position.

[0126] The moving mechanism 120 involved in this application embodiment can be implemented in various ways. For example, it may include, but is not limited to, metal springs, metal bushings, etc. For ease of understanding, please refer to... Figure 12 , Figure 12 Specifically shown Figure 11 Possible implementations of the moving mechanism 120 involved in the conductive component 100 shown include: a metal spring 120-1 and a metal bushing 120-2. For example... Figure 12As shown, the second electrical contact 111-2 is connected to the second load member 210-2 via a metal spring 120-1. The first electrical contact 111-1 is electrically connected to the metal shaft of the first load member 210-1 through a metal sleeve 120-2. The third electrical contact 111-3 is electrically connected to the third load member 210-3 through a metal bushing 120-2. Figure 10 and Figure 11 As shown, the metal spring 120-1 and the metal bushing 120-2 can cause the electrical contact 111 to move, thereby making the conductive component 100 present different electrical contact 111 positional relationships in the installed state and the non-installed state.

[0127] Furthermore, the movably configured manner can also be achieved through the elastic conductive part 112, as exemplarily.

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

[0129] In other words, in this embodiment, the electrical contact 111 is part of the elastic conductive portion 112, meaning that the elastic conductive portion 112 has the ability to be electrically connected to a power source, power supply device, or load component. Furthermore, the elastic conductive portion 112 also has the ability to elastically deform, thereby exhibiting different elastic deformation states or non-deformation states. Thus, based on the elastic deformation capability of the elastic conductive portion 112, the electrical contact 111 can be positioned in different locations.

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

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

[0132] In one exemplary embodiment, the conductive element 110 includes a first conductive element 110-1, a second conductive element 110-2, and a third conductive element 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 element 110-1, the second electrical contact 111-2 is located on the second conductive element 110-2, and the third electrical contact 111-3 is located on the third conductive element 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 are movably disposed on the main body of the conductive element 100 or the housing 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 arranged at intervals along the second direction through elastic deformation.

[0133] In summary, by using the moving mechanism 120 or the elastic conductive part 112, the conductive part 100 can be installed such that at least two of the multiple electrical contacts 111 are spaced apart along the second direction. This helps to reduce situations such as poor power supply conductivity and unstable power supply caused by scratching of electrical contacts, and thus avoids possible imaging abnormalities.

[0134] Furthermore, it should be noted that the embodiments of this application do not impose any particular restrictions on the actual structure of each conductive element 110 in the conductive component 100.

[0135] In one exemplary embodiment, a plurality of conductive elements 110 in the conductive component 100 may be disposed on the main body of the conductive component 100 or the housing 340 of the processing box 300. The main body of the conductive component 100 or the housing 340 of the processing box 300 is provided with protrusions 130 spaced apart along a second direction. The protrusions 130 are provided with conductive elements 110, enabling the electrical contacts 111 of the conductive elements 110 to be electrically connected to a power source or power supply component. As mentioned above, to achieve installation matching with the image forming apparatus 200, the position of the protrusions 130 matches the position of the guide groove in the image forming apparatus 200. When the conductive component 100 or the processing box 300 with the conductive component 100 is installed into the image forming apparatus 200, the protrusions 130 extend into the guide groove and slide along the guide groove (i.e., the installation direction) until correctly installed. In the case of correct installation, the electrical contacts 111 in the conductive component 100 are electrically connected to the power supply component 210 in the image forming apparatus 200. In addition, as mentioned above, the protrusions 130 where the electrical contacts are located can be spaced a certain distance apart, and / or, insulating material can be provided to avoid problems such as short circuits or breakdowns.

[0136] Furthermore, the conductive element 110 involved in the embodiments of this application can have various specific forms, such as a conductive pillar (i.e., a columnar structure), a conductive sheet (i.e., a sheet-like structure), or any other form that can be used for electrical connection. The embodiments of this application do not have any particular limitations in this regard. In addition, the conductive element 110 can be formed by secondary injection molding and embedding of conductive plastic, or the conductive element 110 can be formed by covering the plastic surface with a conductive sheet, which will not be elaborated further.

[0137] Furthermore, this application embodiment does not impose any particular limitation on the relative positional relationship between the conductive element 110 and the protrusion 130. The conductive element 110 may be disposed at the top of the protrusion 130, and / or the conductive element 110 may also be disposed on the side of the protrusion 130. Further, the conductive element 110 may be specifically disposed on any one side in the second direction.

[0138] In one exemplary embodiment, such as Figure 13 and Figure 14 As shown, the outer surface of the protrusion 130 includes an end face and a side face. A first electrical contact 111-1 is disposed on the end face of the protrusion 130, while a second electrical contact 111-2 and a third electrical contact 111-3 are disposed on the side face of the protrusion 130. Specifically, the protrusion 130 may have a first recess and a second recess on its two side faces in the second direction, respectively. The second electrical contact 111-2 (which can be electrically connected to the powder feeding roller) is at least partially disposed in the first recess, and the third electrical contact 111-3 is at least partially disposed in the second recess. Thus, when the conductive component 100 or the processing cartridge 300 equipped with the conductive component 100 is installed in the image forming apparatus 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 plurality of electrical contacts 111 in the conductive component 100 may all be disposed on the end face of the protrusion 130. For example, the conductive component 100 may have a plurality of protrusions 130, such that the first electrical contact 111-1 is disposed on the end face of the first protrusion 130-1, the second electrical contact 111-2 is disposed on the end face of the second protrusion 130-2, and the third electrical contact 111-3 is disposed on the end face of the third protrusion 130-3. In this embodiment, the positional relationship between the plurality of protrusions 130 also satisfies the positional relationship of each electrical contact 111 in the embodiments of this application. For example, the three protrusions 130 may be arranged in a "<" shape on the plane formed by the second direction and the first direction, and the three electrical contacts 111 may be located on the end faces of the three protrusions 130 respectively, thus 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 be arranged in a "<" shape, and each electrical contact 111 may be located on the same side of each protrusion 130, etc., to name a few. Alternatively, in another exemplary embodiment, the plurality of electrical contacts 111 in the conductive member 100 may all be located on the side of the protrusion 130. Further details are omitted.

[0140] In summary, the conductive component 100 provided in this application embodiment can be used to achieve installation matching between the processing box 300 and the image forming apparatus 200. Furthermore, since at least two of the plurality of electrical contacts 111 in the conductive component 100 are spaced apart along the second direction, the number of electrical contact scratches generated in a single installation process can be reduced during the installation of the conductive component 100 or the processing box 300 equipped with the conductive component 100 along the installation direction. This effectively reduces the occurrence of poor conductivity and unstable power supply caused by the scratching of the electrical contacts 111, and thus avoids possible imaging abnormalities.

[0141] This application embodiment also provides a processing box 300. The processing box 300 includes:

[0142] Box body 340;

[0143] At least one load member 310 includes a roller 311 rotatably mounted on the housing 340; and

[0144] Conductive component 100, the conductive component 100 includes:

[0145] Multiple conductive elements 110 are used to realize the electrical connection between the power supply element 210 of the image forming apparatus 200 and the load element 310 of the processing box 300, and at least one load element 310 includes a roller element 311.

[0146] The conductive element 110 includes an electrical contact 111, which is used to contact the power supply element 210 to connect to a power source.

[0147] Among them, at least two of the plurality of electrical contacts 111 are spaced apart along the second direction;

[0148] The second direction intersects with both the third and first directions;

[0149] The third direction is parallel to the axial direction of the roller 311, and the installation direction of the processing box 300 is the first direction.

[0150] In this embodiment, the possible implementations of the conductive component 100 can be referred to the preceding text, and are briefly described below. In this embodiment, the processing box 300 may be provided with the conductive component 100, and its arrangement can be varied: the conductive component 100 may be detachably disposed on the box body 340; or, the conductive component 100 may be fixedly disposed on the box body 340; or, the conductive component 100 and the box body 340 may be disposed independently. This application does not impose a mandatory binding restriction on the processing box 300 and the conductive component 110; the two can exist independently or be used in conjunction.

[0151] Regarding the orientation within the processing box 300, the first orientation is parallel to the mounting orientation of the processing box 300 and also parallel to the extension direction of the guide groove 221 in the image forming apparatus 200. At the implementation level, this application also provides several possible embodiments as follows.

[0152] In one exemplary embodiment, the first direction is parallel to the line connecting the first and second projection positions. The processing box 300 includes a positioning member 320. The first projection position is the projection position of the axis of the roller 311 along a third direction, and the second projection position is the projection position of the positioning member 320 along a third direction. The conductive component 100 is generally also provided with a positioning member 320, which is generally in the form of a protrusion or a recess, used to position the processing box 300 during installation. For example, the positioning member 320 can specifically be a positioning protrusion. When the processing box 300 is inserted into the image forming apparatus 200 along the installation direction, the positioning protrusion can engage with the positioning recess in the image forming apparatus 200 to achieve the installation positioning function. In actual scenarios, the positioning member 320 can be located on the same side as the electrical contact 111 or 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, which includes a plurality of functional electrical contacts 331, with a first direction parallel to the sequential arrangement direction of the plurality of functional electrical contacts 331. The information processing device 330 can specifically be any device or component within the processing box 300 that possesses information processing capabilities; for example, the information processing device 330 may include, but is not limited to, a chip. The information processing device 330 can transmit information, instructions, or other data to other devices through the functional electrical contacts 331.

[0154] Alternatively, in another exemplary embodiment, the processing box 300 includes an information processing device 330, which includes a functional electrical contact 331. The first direction is parallel to 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.

[0155] In a processing box 300 provided in this application embodiment, at least two of the plurality of electrical contacts 111 have projection positions along the second direction that at least partially overlap; or, at least two of the plurality of electrical contacts 111 have projection positions along the second direction that at least partially overlap with a first region; wherein, the first region is the projection region of the outer contour of the roller shaft of the roller 311 in the second direction. Regarding the first region, please refer to the relevant description above, which will not be repeated here.

[0156] In a processing box 300 provided in this embodiment, 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, the second electrical contact 111-2, and the third electrical contact 111-3 are located on the same side of the conductive component. The first electrical contact 111-1 and the second electrical contact 111-2 or the third electrical contact 111-3 protrude at different distances in the third direction. This facilitates electrical connection with the power supply component 210 or the power source, and also facilitates the installation and positioning of the processing box 300. Therefore, in this embodiment, the positioning component can be further omitted, and the installation and locking between the processing box 300 and the image forming apparatus 200 can be achieved directly through the conductive component 110. When the processing box 300 is installed, the protruding electrical contacts 111 can no longer be inserted forward in the installation direction, thus achieving this installation and positioning effect.

[0157] Furthermore, the first electrical contact 111-1 protrudes in the third direction relative to the second electrical contact 111-2 and the third electrical contact 111-3; or, the distance between the second electrical contact 111-2 and the first electrical contact 111-1 or the third electrical contact 111-3 protruding in the third direction increases or decreases sequentially. In this embodiment, there is no particular limitation on the protrusion distance of each electrical contact 111 in the third direction; their relative positional relationships can be designed arbitrarily and will not be elaborated further.

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

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

[0160] In another exemplary embodiment, at least two of the plurality of electrical contacts 111 may be spaced apart in the second direction or staggered in the first direction but close to each other, for example, the projected positions of the plurality of electrical contacts 111 in the second direction at least partially overlap.

[0161] In another exemplary embodiment, at least two of the plurality of electrical contacts 111 may be spaced apart in the second direction and protrude upward at different distances in the third direction. For example, the protrusion length may increase or decrease sequentially along the second direction. Alternatively, they may be staggered in the first direction but closer together. For example, the projection positions of the plurality of electrical contacts 111 in the second direction may at least partially overlap or overlap with the first region.

[0162] Furthermore, in a processing box 300 provided in this application embodiment, the processing box 300 includes a plurality of electrical contacts 111, the plurality of electrical contacts 111 including a first electrical contact 111-1, a second electrical contact 111-2 and a third electrical contact 111-3, and a load member 310 including a first load member 310-1, a second load member 310-2 and a third load member 310-3. The first electrical contact 111-1 is electrically connected to the first load member 310-1, the second electrical contact 111-2 is electrically connected to the second load member 310-2, and the third electrical contact 111-3 is electrically connected to the third load member 310-3. At least two of the first load member 310-1, the second load member 310-2 and the third load member 310-3 are different. 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 a second direction. As mentioned above, there are at least two types of load components, one or more of which may be different in terms of type, model, or value.

[0163] The load element 310 involved in the embodiments of this application may include, but is not limited to, at least one of the following: roller 311, powder discharge knife, fixed resistor, and variable resistor.

[0164] The roller 311 involved in the embodiments of this application may include, but is not limited to: developing roller and / or powder feeding roller and / or photosensitive drum.

[0165] In the processing box 300 provided in this application embodiment, the connection relationship between the electrical contact 111 and the load component 310 is not particularly limited. In practical scenarios, one electrical contact 111 can be used to electrically connect to one load component 310, or it can be used to electrically connect to multiple load components 310. The electrical connection between the electrical contact 111 and the load component 310 can be a direct contact connection, or an indirect electrical connection through a bridging device (such as the moving mechanism 120 mentioned later). Exemplarily, this application embodiment provides the following possible implementation methods.

[0166] In one exemplary embodiment, the first load member 310-1 includes a developing roller, the second load member 310-2 includes a powder feeding roller, and the third load member 310-3 includes a powder discharging blade. A first electrical contact 111-1 is electrically connected to the developing roller, the second electrical contact 111-2 is electrically connected to the powder feeding roller, and the third electrical contact 111-3 is electrically connected to the powder discharging blade. Figure 10 As shown, the first electrical contact 111-1 can be located on the end face of the protrusion 130, and pass through the interior of the protrusion 130 and be electrically connected to the developing roller; while the powder feeding roller and the powder discharging blade 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 can be located on both sides of the protrusion.

[0167] Alternatively, in another exemplary embodiment, the first load element 310-1 further includes a powder feeding roller, which is connected in parallel with the developing roller and then electrically connected to the first electrical contact 111-1. In this embodiment, the first electrical contact 111-1 is electrically connected to multiple first load elements 310-1 (i.e., the powder feeding roller and the developing roller). In practical scenarios, this can be achieved using the voltage divider circuit described above, and the branches of the voltage divider circuit can also be additionally designed with one or more modules such as a voltage adjustment module, a current adjustment module, and a power adjustment module.

[0168] Alternatively, in another exemplary embodiment, the first load element 310-1 further includes a powder feeding roller and a powder discharging blade, which are connected in parallel and electrically connected to the first electrical contact 111-1. In this embodiment, the first electrical contact 111-1 is electrically connected to the three first load elements 310-1 (i.e., the powder feeding roller, the powder discharging blade, and the developing roller), which can be achieved by a voltage divider circuit. The branches of the voltage divider circuit can also be additionally designed with one or more of the following: a voltage adjustment module, a current adjustment module, and a power adjustment module.

[0169] As mentioned above, this will not be repeated here.

[0170] Furthermore, in this embodiment of the application, the plurality of electrical contacts 111 in the processing box 300 are spaced apart in the second direction. This could be that the plurality of electrical contacts 111 are spaced apart in a fixed manner in the second direction, or that at least one of the plurality of electrical contacts 111 is movable.

[0171] For example, the movable configuration can be achieved by a moving mechanism 120. In one exemplary embodiment, the conductive component 100 further includes a moving mechanism 120 for moving at least two of the plurality of conductive components 110 from a first position to a second position; at least two electrical contacts 111 located at the second position are spaced apart along a second direction.

[0172] At this time, as Figure 10 As shown, the conductive element 110 includes a first conductive element 110-1, a second conductive element 110-2, and a third conductive element 110-3. 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 element 110-1, the second electrical contact 111-2 is located on the second conductive element 110-2, and the third electrical contact 111-3 is located on the third conductive element 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 housing 340 of the processing box 300.

[0173] The moving mechanism 120 is an elastic element. The first conductive element 110-1 and / or the second conductive element 110-2 and / or the third conductive element 110-3 are disposed on the main body of the conductive component or the box 340 of the processing box 300 through the elastic element. The first conductive element 110-1 and / or the second conductive element 110-2 and / or the third conductive element 110-3 move at least two of the multiple conductive elements 110 from the first position to the second position through the elastic deformation of the elastic element, 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.

[0174] Furthermore, the movably configured manner can also be achieved through the elastic conductive portion 112. In one exemplary embodiment, in the processing box 300, at least two of the plurality of conductive elements 110 include elastic conductive portions 112. The elastic conductive portions 112 are used to contact the power supply element 210 to access power. When the elastic conductive portion 112 contacts the power supply element 210, it is in an elastically deformed state. The contact portion between the elastic conductive portion 112 and the power supply element 210 is an electrical contact 111. In this case, the electrical contacts 111 of the elastic conductive portions 112 of at least two conductive elements 110 have different first projection lengths in the second direction.

[0175] In one embodiment of this situation, the conductive element 110 includes a first conductive element 110-1, a second conductive element 110-2, and a third conductive element 110-3. 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 element 110-1, the second electrical contact 111-2 is located on the second conductive element 110-2, and the third electrical contact 111-3 is located on the third conductive element 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 are movably disposed on the main body of the conductive component or the housing 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 arranged at intervals along the second direction through elastic deformation.

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

[0178] Furthermore, in one embodiment of this application, the plurality of electrical contacts 111 in the processing box 300 are spaced apart by an insulating material. For example, the electrical contacts 111 or the protrusions 130 where the electrical contacts 111 are located may be spaced apart by a certain distance, and / or an insulating material may be provided to avoid problems such as short circuits or breakdowns.

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

[0180] Furthermore, in one embodiment of this application, the processing box 300 includes a plurality of electrical contacts 111, including 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 face and a side face, and the first electrical contact 111-1 is disposed on the end face 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 face of the protrusion 130.

[0181] Understandably, the processing box 300 also has different specifications depending on the type of image forming apparatus 200:

[0182] When the image forming apparatus 200 only has black and white printing function, usually only one processing box 300 needs to be installed in one image forming apparatus 200;

[0183] When the image forming apparatus 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 to print cyan, magenta, yellow, and black respectively. In one printing job, the four processing boxes 300 can perform solid color printing individually, or they can print various different colors by superimposing and mixing the above four colors. At this time, at least one processing box 300 can be equipped with the above conductive component 100. Of course, the processing box 300 may also be used for printing other colors, not limited to the above colors.

[0184] For details not covered herein, please refer to the preceding text; further explanation is not required here.

[0185] This application also provides an image forming apparatus 200. For example... Figure 3 and Figure 5 As shown, the image forming apparatus 200 includes:

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

[0187] Multiple power supply components 210;

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

[0189] The first direction is parallel to the extension 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 side 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 this embodiment, the first direction is parallel to the extension direction of the guide groove 221 and also parallel to the installation direction of the processing box 300. Its possible implementation can be found above and will not be repeated here. The second direction and the first direction are respectively parallel to the plane containing the inner side plate 220. In other words, the plane formed by the second direction and the first direction is parallel to the plane containing the inner side plate 220.

[0192] In this embodiment, the processing box 300 and the conductive component 100 are adapted to be installed with the image forming apparatus 200. Based on this, similar to the plurality of electrical contacts 111 mentioned above, at least two of the plurality of power supply components 210 are also spaced apart along the second direction. The spacing can be achieved by maintaining a certain physical distance or by using insulating material for spacing.

[0193] In another possible embodiment of this application, at least two of the projection positions of the plurality of power supply units 210 in the image forming apparatus 200 along the second direction at least partially overlap; or, at least two of the projection positions of the plurality of power supply units 210 along the second direction at least partially overlap with the first region.

[0194] Furthermore, in another possible embodiment of this application, the distances by which the plurality of power supply components 210 in the image forming apparatus 200 protrude in the third direction can be different. The third direction intersects with the first and second directions; preferably, the third direction can be perpendicular to the first and second directions, respectively. Moreover, in the installation scenario of the processing cartridge 300, the third direction can also be parallel to the axial direction of the roller 311. Further details are omitted.

[0195] Furthermore, in specific implementations of this application embodiment, the plurality of power supply components 210 may include: a first power supply component, a second power supply component, and a third power supply component. In one implementation, the first power supply component may be recessed relative to the second and third power supply components in a third-direction upward direction; to adapt to the power supply structure design of the image forming apparatus 200, the first electrical contact 111-1 in the conductive component 100 may also be protruding relative to the second electrical contact 111-2 and the third electrical contact 111-3 in a third-direction upward direction. Alternatively, in another implementation, the distance between the second power supply component and the first or third power supply component recessed in a third-direction direction sequentially increases or decreases; correspondingly, to adapt to this design, the distance between the second electrical contact 111-2 and the first electrical contact 111-1 or the third electrical contact 111-3 protruding in a third-direction direction in the conductive component 100 sequentially increases or decreases.

[0196] For the image forming apparatus 200, the positions of the multiple power supply components 210 are generally fixed. Based on the above design, when the conductive component 100 or the processing box 300 equipped with the conductive component 100 is installed in the image forming apparatus 200, unnecessary scratching of electrical contacts can be avoided. Thus, by reducing the number of contacts and scratches between the electrical contacts and the power supply components during a single installation of the processing box, this embodiment of the application can effectively reduce poor conductivity and unstable power supply caused by scratching of electrical contacts, thereby avoiding possible imaging abnormalities and improving power supply stability.
