[0010] The second direction intersects with the first direction, and the second direction is parallel to the axial direction of the roller.

[0011] According to another aspect of this application, a processing box is provided, comprising:

[0012] Box body;

[0013] At least one of the load members includes a roller rotatably disposed on the housing; and

[0014] The conductive component includes:

[0015] Multiple conductive elements are provided to enable electrical connection between the power supply element of the image forming apparatus and the load element.

[0016] The conductive component includes an electrical contact, which is used to contact the power supply component to connect to a power source;

[0017] Wherein, at least two of the plurality of electrical contacts have different first projection lengths in the second direction;

[0018] The first projection length is the length between the first projection position and the second projection position; the first projection position is the projection position of the electrical contact in the second direction; the second projection position is the projection position of the first reference position in the second direction.

[0019] The first reference position is any point on the side of the conductive component away from the electrical contact;

[0020] Wherein, the second direction intersects with the first direction, the second direction is parallel to the axial direction of the roller, and the installation direction of the processing box is the first direction.

[0021] According to another aspect of this application, an image forming apparatus is provided, comprising:

[0022] The body includes an inner side plate, and the inner side plate is provided with a guide groove;

[0023] Multiple power supply components;

[0024] Among them, at least two of the contact portions of the plurality of power supply components have different first projection lengths formed in the second direction, and they increase sequentially along the first direction;

The first direction in this application is the mounting direction of the processing box, and the second direction is parallel to the axial direction of the roller. Based on this, by designing that at least two of the plurality of electrical contacts have different first projected lengths in the second direction, the lengths of at least two conductive components in the axial direction of the roller can be different. Thus, by matching the lengths of the conductive components with the image forming apparatus, precise positioning and matching between the conductive components and the power supply components can be achieved. Therefore, while ensuring electrical contact and conductivity between the electrical contacts and the power supply components, the length of the conductive components in the second direction, which is inherently required, assists in achieving positioning and matching. This not only provides better conductivity and stability but also, in some embodiments, allows for the omission of positioning components or eliminates the need for special precision requirements and cost associated with them. In summary, the technical solution provided by this application can achieve both conductivity and positioning assistance, which is beneficial for improving positioning accuracy.

[0059] To make the objectives, technical solutions, and advantages of this application more apparent, exemplary embodiments according to this application will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein.

[0060] This application provides a conductive component.

[0061] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the architecture of a conductive component provided in an embodiment of this application. Figure 2 for Figure 1 A top view of the conductive component shown. (As shown) Figure 1 and 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.

[0062] It should be understood that Figure 1 Three conductive elements 110 are shown, which can be respectively designated as: first conductive element 110-1, second conductive element 110-2, and third conductive element 110-3; correspondingly, Figure 1 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 1 This is merely an example; in real-world scenarios, there may be more or fewer conductive elements 110, and this application 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.

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

[0064] It should be noted that the first projection position A1 refers to the projection position obtained by projecting the electrical contact 111 onto the second direction (a line) or the plane containing the second direction. More specifically, it can be the projection position obtained by projecting the electrical contact 111 onto the plane containing both the second and first directions, such as... Figure 1 As shown. In a real-world scenario, the electrical contact 111 can be projected along a direction perpendicular to the plane containing the second direction (e.g., the third direction mentioned later, denoted as D3) to obtain the relevant projection position. Similarly, the second projection position A2 refers to the projection position obtained by projecting the first reference position 113 onto the second direction or the plane containing the second direction. Further, it can be the projection position obtained by projecting the first reference position 113 onto the plane containing both the second and first directions, such as... Figure 1 As shown. No further explanation needed.

[0065] In this embodiment, the second direction is parallel to the axial direction of the roller. The second direction intersects the first direction (denoted as D1). 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 and the first direction can be perpendicular to each other. In this embodiment, the first direction is 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 3 As 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 have different first projection lengths in a second direction. In this embodiment, the second direction intersects with the first direction, the second direction is parallel to the axial direction of the roller, and the first direction is the mounting direction of the processing cartridge 300.

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

[0071] 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.

[0072] 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 via the conductive component 100, the roller 311 can be electrically connected to the power supply via 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 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, the fixedly installed roller 311 is used as a reference, and a second direction is determined based on the axial direction of the roller 311. That is, the second direction is parallel to the axial direction of the roller 311. Preferably, in one embodiment, the second direction is parallel to the axial direction of the developing roller.

[0073] 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.

[0074] Combination Figure 3 and Figure 4 For example. Figure 4 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, at least one of the conductive members 110 can generally protrude (i.e., protrude from the side of the conductive member 100 to which it is located). 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 3 As shown.

[0075] Furthermore, in the embodiments of this application, such as Figure 5 As shown, the image forming apparatus 200 is further provided with a plurality of power supply components 210. At least two of the contact portions 211 of the plurality of power supply components 210 have different first projection lengths in the second direction. Furthermore, for a set of power supply components 210 and conductive components 110 that can be adapted under normal installation conditions, if the first projection length of the contact portion 210 of the power supply component 210 in the second direction is longer, then the corresponding electrical contact 111 of the conductive component 110 has a shorter first projection length in the second direction.

[0076] For example, Figure 5 One possible embodiment is shown in which at least two of the contact portions 211 in the plurality of power supply components 210 have different first projected lengths in the second direction, and these lengths increase sequentially along the first direction; while at least two of the electrical contacts 111 in the conductive components 100 have different first projected lengths in the second direction, and their arrangement order decreases sequentially along the first direction. Thus, when the conductive components 100 or the processing box 300 equipped with the conductive components 100 are correctly installed with the image forming apparatus 200, an image can be formed as shown... Figure 4 The electrical connections are shown.

[0077] In other words, the position of the electrical contact 111 can match that of the power supply component 210, so that after the two are installed and matched, the electrical contact 111 can contact and connect with the power supply component 210. In this embodiment, the first direction can also be understood as the insertion / removal direction of the processing box 300, or as the extension direction of the guide groove 221 in the image forming apparatus 200, wherein the guide groove 221 is disposed 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.

[0078] Thus, at least two of the multiple electrical contacts 111 have different first projected lengths in the second direction, which can make at least two conductive elements 110 have different lengths in the axial direction of the roller. By matching the length of the conductive element 110 with that of the image forming apparatus 200, precise positioning matching between the conductive element 110 and the power supply element 210 can be achieved. Therefore, while ensuring that the contact portion 211 of the electrical contact 111 and the power supply element makes contact and conducts electricity, the length of the conductive element 110, which is inherently required, in the second direction assists in achieving positioning matching. This not only provides better conductivity and stability, but also, in some embodiments, eliminates the need for a positioning element or eliminates the need for special precision requirements and costs associated with it. In summary, the technical solution provided in this application can achieve both conductivity and positioning assistance, which is beneficial for improving positioning accuracy.

[0079] 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.

[0080] In one exemplary embodiment, the first direction is parallel to the line connecting the third and fourth projection positions. The processing box 300 includes a positioning member 320. The third projection position is the projection position of the axis of the roller 311 along the second direction, and the fourth projection position is the projection position of the positioning member 320 along the second direction. In this embodiment, the third and fourth projection positions are determined by the projection of the relevant devices along the second direction onto a plane perpendicular to the second direction. In practical scenarios, the conductive component 100 is generally also provided with a positioning member 320. The positioning member 320 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 a real-world scenario, the positioning element 320 can be positioned on the same side as the electrical contact 111, or it can be positioned on the opposite side of the processing box 300.

[0081] Alternatively, in another exemplary embodiment, the processing box 300 includes an information processing device 330, such as... Figure 7 As shown, the information processing device 330 includes a plurality of functional electrical contacts 331, 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 6The information processing device 330 may have four functional electrical contacts 331, namely a power contact (Volt Current Condenser, VCC), a data signal contact (Serial Data, SDA), a clock signal contact (Clock, CLK), and a ground contact (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.

[0082] 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.

[0083] 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 described above, or they may not be arranged in the same direction as the conductive terminals described above.

[0084] 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.

[0085] 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.

[0086] Alternatively, in another exemplary embodiment, the processing box 300 includes an information processing device 330, which includes a plurality of functional electrical contacts 331. A 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 a second direction, and the third projection position is the projection position of the functional electrical contacts 331 along the second 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.

[0087] 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.

[0088] Similarly, the information processing device 330 may have other types of terminals that do not directly contact the electrical contacts of the image forming device, and such terminals cannot be used to form a third projection position.

[0089] 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.

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

[0091] In practical implementation scenarios, the first projected length of multiple electrical contacts 111 can be set to increase or decrease in a certain order, such as in the first direction and / or the third direction.

[0092] In one exemplary embodiment, at least two of the plurality of electrical contacts 111 are spaced apart along a first direction; the first projection length of at least two of the plurality of electrical contacts 111 in a second direction decreases sequentially according to the arrangement order of the corresponding electrical contacts 111 along the first direction. Figure 4This situation is illustrated. In this embodiment, since the first projection lengths of each electrical contact 111 in the second direction are different, during the installation of the conductive component 100 or the processing box 300 provided with the conductive component 100, in addition to achieving the effect of contact conductivity or auxiliary positioning, it can further prevent the electrical contact 111 from rubbing against the contact portion 211 of the power supply component 210, avoid unnecessary rubbing contact during a single installation, reduce the possibility of power supply instability due to frequent rubbing, and further improve power supply stability.

[0093] Furthermore, the first projected length corresponding to each electrical contact 111 can be greater than, equal to, or less than the second projected length, where the second projected length is the distance between the second projected position and the plane where the electrical contact is located (e.g., the left side mentioned earlier). Generally, at least one of the multiple electrical contacts has a first projected length greater than the second projected length in the second direction; in other words, at least one of the multiple electrical contacts can generally protrude from its plane. Still using... Figure 1 and Figure 5 For example, in the case shown, Figure 5 The electrical contacts 111 of the three conductive elements 110 can all protrude from the plane of the conductive component 100 where the conductive element 110 is located; or, Figure 1 and Figure 5 Of the three conductive elements 110, only one electrical contact 111 may be protruding, while the other electrical contacts 111 may be flush with or further recessed on the plane of the conductive component 100 where the conductive element 110 is located. This will not be elaborated further.

[0094] Furthermore, this application embodiment does not impose any particular restrictions on the arrangement of the multiple electrical contacts 111 in the first direction and the third direction. In actual implementation scenarios, the multiple electrical contacts 111 can be arranged at intervals in the first direction and / or the third direction.

[0095] In one exemplary embodiment, as described above Figure 1 and Figure 5 As shown, multiple electrical contacts 111 can be spaced apart along a first direction. In this embodiment, the multiple electrical contacts 111 can be arranged flush with each other in a second direction, or they can be spaced apart. The spacing can be achieved by maintaining a certain physical space, or, in a preferred embodiment, by using insulating material to prevent short circuits or breakdowns.

[0096] Furthermore, in this embodiment, the projected positions of the plurality of electrical contacts 111 in the conductive component 100 in the second direction can be relatively close.

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

[0098] Alternatively, in another possible embodiment, at least two of the plurality of electrical contacts 111 have projection positions along a first direction that at least partially overlap with a first region; wherein the first region is the projection area of ​​the outer contour of the roller shaft of the roller 311 in the first direction. Specifically, when the processing cartridge 300 is specifically 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. At this time, reference can be made to... Figure 8 ,like Figure 8 As shown, viewed from the axial direction of the developing roller (a third direction, also the side view of the conductive component 100), 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 first direction is the interval [A, B] between point A and point B. In this embodiment, at least two of the multiple electrical contacts 111 have projection positions along the first 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 second direction and spaced apart in the first direction, such as... Figure 8 As shown, the multiple electrical contacts 111 are arranged horizontally in the first direction.

[0099] 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 third electrical contact 111-3, the second electrical contact 111-2 and the first electrical contact 111-1 are located on the same side of the conductive component and are arranged sequentially along a first 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] As mentioned above, this will not be repeated here.

[0107] Furthermore, in this embodiment of the application, the plurality of electrical contacts 111 in the processing box 300 may be arranged in a fixed form, or at least one of the plurality of electrical contacts 111 may be arranged movably.

[0108] 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 elements 110 from a first position to a second position; the electrical contacts 111 of the at least two conductive elements 110 located at the second position have different first projected lengths in a second direction.

[0109] Further, in this 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. 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 component 100 or the housing 340 of the processing box 300.

[0110] 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 have different first projection lengths in the second direction.

[0111] 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.

[0112] 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.

[0113] Among them, the first conductive element 110-1 and / or the second conductive element 110-2 and / or the third conductive element 110-3 undergo elastic deformation to make the first electrical contact 111-1, the second electrical contact 111-2 and the third electrical contact 111-3 have different first projection lengths in the second direction.

[0114] Furthermore, in a preferred embodiment of this application, the second direction is perpendicular to the third direction and the first direction.

[0127] 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.

A load member 310 includes 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 third electrical contact 111-3, the second electrical contact 111-2, and the first electrical contact 111-1 are located on the same side of the conductive component 100 and are arranged sequentially along a first direction. As mentioned above, at least two types, models, or values ​​of the load members may be different.

[0135] 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.

[0136] 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.

[0137] 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.

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.

[0140] 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.

[0141] As mentioned above, this will not be repeated here.

[0142] Furthermore, in this embodiment of the application, the plurality of electrical contacts 111 in the processing box 300 may be arranged at intervals in a fixed form, or at least one of the plurality of electrical contacts 111 may be arranged movably.

[0143] 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 elements 110 from a first position to a second position; the electrical contacts 111 of the at least two conductive elements 110 located at the second position have different first projected lengths in a second direction.

[0144] 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. 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. This allows the first electrical contact 111-1 and / or the second electrical contact 111-2 and / or the third electrical contact 111-3 to be movably disposed on the main body of the conductive component 100 or the housing 340 of the processing box 300.

[0145] 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 have different first projection lengths in the second direction.

[0146] 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.

[0147] 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.

[0148] Among them, the first conductive element 110-1 and / or the second conductive element 110-2 and / or the third conductive element 110-3 undergo elastic deformation to make the first electrical contact 111-1, the second electrical contact 111-2 and the third electrical contact 111-3 have different first projection lengths in the second direction.

[0149] Furthermore, in a preferred embodiment of this application, the second direction is perpendicular to the first direction.

[0150] 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.

[0151] Understandably, the processing box 300 also has different specifications depending on the type of image forming apparatus 200:

[0152] When the image forming apparatus 200 only has black and white printing function, one processing box 300 is usually required to be installed in one image forming apparatus 200.

[0153] 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.

[0154] For details not covered herein, please refer to the preceding text; further explanation is not required here.

[0155] This application also provides an image forming apparatus 200. For example... Figure 3 and Figure 4 As shown, the image forming apparatus 200 includes:

[0156] The body 240 includes an inner side plate 220, on which a guide groove 221 is provided;

[0157] Multiple power supply components 210;

[0158] Among them, at least two of the contact portions 211 of the plurality of power supply components 210 have different first projected lengths in the second direction;

[0159] The first direction is parallel to the extension direction of the guide groove 221, and the second direction intersects with the plane where the inner side plate 220 is located.

[0160] The guide groove 221 is used to guide the installation direction of the conductive component 100 or the processing box 300.

[0161] In a further embodiment, at least two of the contact portions 211 among the plurality of power supply components 210 have different first projected lengths in the second direction, and these lengths increase sequentially along the first direction. Referring to the preceding text, further details are omitted.

[0162] 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.

[0163] 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 form different first projection lengths in the second direction. The spacing can be arranged by a certain physical distance or by spacing through insulating material.

[0164] 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 first direction at least partially overlap; or, at least two of the projection positions of the plurality of power supply units 210 along the first direction at least partially overlap with the first region.

[0165] Furthermore, in another possible embodiment of this application, the plurality of power supply units 210 in the image forming apparatus 200 are spaced apart in a third direction and / or a first direction. The third direction intersects with the first and second directions, and preferably, the third direction may be perpendicular to the first and second directions respectively. Moreover, in the installation scenario of the processing cartridge 300, the third direction may also be parallel to the axial direction of the roller 311. Further details are omitted.

[0166] Furthermore, in specific implementations of this application embodiment, the plurality of power supply components 210 may include: a first power supply component 210-1, a second power supply component 210-2, and a third power supply component 210-3. In one implementation, the first power supply component 210-1 may be recessed relative to the second power supply component 210-2 and the third power supply component 210-3 in a second 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 protrude relative to the second electrical contact 111-2 and the third electrical contact 111-3 in a second direction. Alternatively, in another implementation, the distance between the recessed portion of the second power supply component 210-2 and the first power supply component 210-1 or the third power supply component 210-3 along the second direction increases or decreases sequentially; correspondingly, to adapt to this design, the distance between the protruding portion of the second electrical contact 111-2 and the first electrical contact 111-1 or the third electrical contact 111-3 along the second direction in the conductive component 100 increases or decreases sequentially.

[0167] 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, by designing that at least two of the multiple electrical contacts have different first projection lengths in the second direction, the lengths of at least two conductive components in the axial direction of the roller can be different. Thus, by matching the length of the conductive component with the length of the image forming apparatus, precise positioning matching between the conductive component and the power supply component can be achieved. Therefore, under the premise of ensuring electrical contact and conductivity between the electrical contacts and the power supply component, the length of the conductive component in the second direction, which is required by the apparatus itself, is used to assist in achieving positioning matching. This not only provides better conductivity and stability, but also, in some embodiments, the positioning component can be omitted or there are no special precision requirements or costs associated with the positioning component. In summary, the technical solution provided by this application can achieve both conductivity and positioning assistance, which is beneficial for improving positioning accuracy.
