Detailed Description
The present application is described in further detail below with reference to specific embodiments and with reference to the attached drawings.
As shown in fig. 1 to 6, the present embodiment provides a process cartridge which can be applied to an image forming apparatus such as a printer, a copier, and the like, and in particular, which is detachably mounted in the image forming apparatus, and which may specifically include a developing cartridge 100, a drum cartridge 200, and a conductive coupling member 300. The developing cartridge 100 and the drum cartridge 200 may be detachably attached. In one structure, the drum cartridge 200 may be provided with a first protruding shaft 210 and a second protruding shaft 220, the developing cartridge 100 is correspondingly provided with a first slideway 110 and a second slideway 120, the first protruding shaft 210 is matched with the first slideway 110, and the second protruding shaft 220 is matched with the second slideway 120, so as to realize the assembly between the developing cartridge 100 and the drum cartridge 200. Wherein the first and second ramps 110 and 120 enable the movement trajectory of the drum cartridge 200 mounted to the developing cartridge 100 to be perpendicular to the laser path plane 130 inside the developing cartridge 100.
The developing cartridge 100 includes an end cap and a developing cartridge chip 140. The end caps are generally provided in two, a first end cap 150 and a second end cap 160, respectively, and the developing cartridge chip 140 is mounted on the end caps with the contact surfaces of the chip extending in a direction parallel to the plane of the end caps, so that the developing cartridge chip 140 can be viewed by a user from the outside of the process cartridge, and when the process cartridge is mounted inside the image forming apparatus, the developing cartridge chip 140 is electrically connected to conductive contacts (not shown) located inside the image forming apparatus through the end caps. Specifically, the developing cartridge chip 140 may be mounted to the first end cap 150 or the second end cap 160, and the mounting of the developing cartridge chip 140 to the first end cap 150 is described herein as an example. At this time, the developing cartridge chip 140 may be located on an outer surface of the first end cap 150, where the outer surface refers to a surface of the first end cap 150 facing away from a space formed after the developing cartridge 100 is assembled with the drum cartridge 200.
The drum cartridge 200 includes a drum cartridge chip 230, and the drum cartridge chip 230 is located on the bottom surface of the drum cartridge 200, and the contact surface thereof extends substantially along the direction of the bottom surface of the drum cartridge, and may be disposed in a space formed after the assembly of the developing cartridge 100 and the drum cartridge 200.
The conductive connector 300 may be disposed on the developing cartridge 100, and after the conductive connector 300 is disposed, the developing cartridge chip 140 may be electrically connected to the drum cartridge chip 230 through the conductive connector 300, and then the developing cartridge chip 140 is electrically connected to a conductive contact located inside the image forming apparatus, so as to implement voltage and data transmission. At this time, the identification information of the developing cartridge 100 and the drum cartridge 200 and the content of the internal developer or the waste developer can be detected only by the developing cartridge chip 140, without providing conductive contacts to be connected with the developing cartridge chip 140 and the drum cartridge chip 230, and the purpose is achieved by the developing cartridge chip 140 and the drum cartridge chip 230, so that the process cartridge can reduce the number of contacts matched with the developing cartridge chip 140 and the drum cartridge chip 230, thereby reducing the design difficulty of the process cartridge, and simultaneously preventing the problem of poor conduction between the developing cartridge chip 140 and the drum cartridge chip 230 and the contacts.
The above-described structure of the conductive connection member 300 may be flexibly set as long as the electrical connection between the developing cartridge chip 140 and the drum cartridge chip 230 can be achieved. In order to further simplify the structure of the conductive connection member 300, and to control the processing cost and design difficulty of the process cartridge, the conductive connection member 300 may be provided in a bar structure, and one end of the conductive connection member 300 is electrically connected to the developing cartridge chip 140 and the other end is electrically connected to the drum cartridge chip 230. Specifically, the conductive connection member 300 may be a bent or curved structure to accommodate the positions of the developing cartridge chip 140 and the drum cartridge chip 230. In addition, an adapter module may be added between the conductive connector 300 and the developing cartridge chip 140 or the drum cartridge chip 230 for electrical connection.
Example one
As shown in fig. 1-7, in one embodiment, the conductive connector 300 may include: a connecting rod 310 as a connecting member, the connecting rod 310 may be a bent structure to accommodate the positions of the developing cartridge chip 140 and the drum cartridge chip 230; the first elastic column 320 as the first elastic member may be a solid cylinder or a hollow cylinder, which is connected to one end of the connecting rod 310 and connected to the drum cartridge chip 230, and an axis of the first elastic column 320 may be perpendicular to a plane in which the drum cartridge chip 230 is located.
Alternatively, the components of the conductive connector 300 may be formed into an integral structure, for example, a metal wire may be bent to form the conductive connector 300.
That is, the entire conductive connector 300 is vertically connected to the drum cartridge chip 230 by the first elastic column 320 thereof, and when the process cartridge is assembled, the upper surface of the developing cartridge 100 and the bottom surface of the drum cartridge 200 face each other and move relative to each other, and the conductive connector 300 contacts the drum cartridge chip 230 in the moving direction, and therefore, the conductive connector 300 and the drum cartridge chip 230 do not need to be connected by relative sliding, and thus the drum cartridge chip 230 is not easily scratched. In addition, the first elastic column 320 is an elastic structure, and the fit between the first elastic column and the drum cartridge chip 230 is more flexible, so that the drum cartridge chip 230 is more reliably prevented from being scratched.
Similar structure can be adopted for the connection between the conductive connector 300 and the developing cartridge chip 140, as well as the first elastic column 320. Specifically, the conductive connecting member 300 may further include a second elastic column 330 as a second elastic member in addition to the connecting rod 310, and the second elastic column 330 may be a solid cylinder or a hollow cylinder. The second elastic column 330 is connected to the connecting rod 310, which is connected to the developing cartridge chip 140, and the axis of the second elastic column 330 is parallel to the plane of the developing cartridge chip 140. The developing cartridge chip 140 is not easily scratched by the second elastic column 330.
The first elastic column 320 and the second elastic column 330 may be provided separately or simultaneously. In addition, the connecting part may be a pipe or other structure besides the connecting rod 310, and the first elastic member and the second elastic member may be a block structure or other structure besides the columnar structure.
In order to more reliably connect the conductive connector 300 to the developing cartridge chip 140, the connection bar 310 may include: a rod body 311, the rod body 311 being connected to the second elastic column 330, and a bent portion 312, the bent portion 312 being connected to one end of the rod body 311 and bent from one end of the rod body 311. The bent portion 312 can be positioned and matched with the second elastic column 330, that is, the bent portion 312 can be pressed against the casing of the developing cartridge 100 after the developing cartridge 100 is mounted, so as to prevent the second elastic column 330 from moving and causing poor contact with the developing cartridge chip 140, thereby achieving the aforementioned purpose.
Further, the bending portion 312 may include a first rod portion 312a and a second rod portion 312b, both of which are linear structures, the first rod portion 312a is vertically connected to one end of the rod body 311, and the second rod portion 312b is vertically connected to the first rod portion 312 a. The bending portion 312 has the advantages of simple structure and convenient processing.
In an alternative embodiment, the rod 311 may include a first rod segment 311a, a U-shaped rod segment 311b and a second rod segment 311c, the first rod segment 311a is connected to the second rod segment 311c through the U-shaped rod segment 311b, and the U-shaped rod segment 311b is connected to the second elastic column 330. At this time, there is a bent portion in the connecting rod 310, that is, the U-shaped rod segment 311b, and in this structure, the connecting rod 310 is not easily deformed after being stressed, so that the connecting rod 310 can maintain a certain elasticity, and at the same time, the elasticity is not too large, thereby better realizing the connection between the conductive connecting member 300 and the developing cartridge chip 140 and the drum cartridge chip 230.
In order to facilitate the assembly between the conductive connector 300 and the developing cartridge 100, a positioning post 170 may be disposed on the first end cap 150, and the conductive connector 300 further includes an elastic positioning sleeve 340, wherein the elastic positioning sleeve 340 is connected to the connecting rod 310 and is configured to be sleeved with the positioning post 170. When the conductive connecting member 300 is mounted, the elastic positioning sleeve 340 is firstly sleeved on the positioning column 170 to realize the positioning between the two, and then the position of the conductive connecting member 300 is adjusted to be capable of simultaneously contacting with the developing cartridge chip 140 and the drum cartridge chip 230.
Generally, the conductive connection member 300 may be provided in plurality to facilitate transmission of data, voltage, and the like. At this time, in order to prevent contact between the conductive connectors 300, an isolation rib 400 may be provided, the isolation rib 400 protruding with respect to the inner wall of the first end cap 150, and the isolation rib 400 is provided between the adjacent conductive connectors 300. At this time, the isolation ribs 400 can isolate the adjacent conductive connectors 300, and even if the conductive connectors 300 tend to contact each other, the isolation ribs 400 can block the adjacent conductive connectors 300, thereby preventing the adjacent conductive connectors 300 from contacting each other, and further more reliably transmitting data and voltage.
In order to improve the positional accuracy of the conductive connector 300 assembled with the developing cartridge 100, a pressing cover (not shown) may be further provided, the pressing cover being connected to the first end cap 150, and the conductive connector 300 being located between the pressing cover and the first end cap 150. Specifically, the pressing cover and the first end cover 150 may be coupled to each other by a screw connection or by a snap structure. The capping cap may limit the displacement of the conductive connector 300 in a direction perpendicular to the first end cap 150, and thus prevent the conductive connector 300 from exerting an additional force on the developing cartridge chip 140 and the drum cartridge chip 230 when moving in the direction, which may result in damage to the developing cartridge chip 140 and the drum cartridge chip 230, or poor contact between the conductive connector 300 and the developing cartridge chip 140 or the drum cartridge chip 230.
Example two
As shown in fig. 8 to 10, the present embodiment is different from the first embodiment in that the conductive connecting member 300 has a different structure. Specifically, the conductive connection member 300 may include: an elastic connecting sheet 350, the elastic connecting sheet 350 having an elastic sheet structure, a first protrusion 360 as a first conductive portion, the first protrusion 360 connected to one end of the elastic connecting sheet 350 and electrically connected to the drum cartridge chip 230.
When the process cartridge is assembled, the conductive connection member 300 and the drum cartridge chip 230 do not need to be connected by relative sliding, and therefore the drum cartridge chip 230 is not easily scratched. In addition, when the main structure of the conductive connector 300 is a sheet structure, a larger contact area can be formed between the conductive connector 300 and the first end cap 150, so as to control the displacement of the conductive connector 300 relative to the first end cap 150. Meanwhile, the conductive connecting member 300 also has the advantages of simple structure and the like.
Similar structure can be adopted for the connection between the conductive connector 300 and the developing cartridge chip 140, as with the first projection 360.

The bent piece 353 may have a U-shaped structure or may have a structure of another shape. At this time, there is a bent portion in the elastic connection piece 350, that is, the bent sheet 353, and in this structure, the elastic connection piece 350 is not easy to deform after being stressed, so that the elastic connection piece 350 can maintain a certain elasticity, and meanwhile, the elasticity is not too large, thereby better realizing the connection between the conductive connection member 300 and the developing cartridge chip 140 and the drum cartridge chip 230.
