Description
Technical Field
[0001] The utility model relates to the technical field of printing material equipment, in particular to an electrical connection and matching structure for a toner cartridge of a selenium drum.
Background Art
[0002] In the component composition of a selenium drum, a toner cartridge is an important component that cooperates with a drum frame. After the toner cartridge and the drum frame are combined into a selenium drum and installed in a printing device, the toner cartridge needs to be electrically connected to the printing device. Specifically, the printing device identifies data of a developing component located in the toner cartridge by contacting a chip. Most of the existing toner cartridges and drum frames are detachably arranged to facilitate the replacement of the toner cartridge. Further, in terms of the functional requirements of printing material equipment, a structure that can separate or contact the toner cartridge and the drum frame at a short distance is provided between the existing toner cartridge and the drum frame. Specifically, it is a structure that separates or contacts a developing roller in the toner cartridge and a photosensitive drum in the drum frame at a short distance. In order to maintain the electrical connection between the toner cartridge and the printing device when the developing roller and the photosensitive drum are separated or contacted at a short distance, a toner cartridge with an electrical connection and matching structure that can achieve this effect has emerged. However, the existing electrical connection and matching structure is generally composed of multiple parts spliced and combined, with a relatively complex structure, which leads to difficult assembly, increases the part production cost and assembly cost of the product, and reduces the competitiveness of the product in the market. Therefore, there is an urgent need for an electrical connection and matching structure with a simple structure.
Summary of the Invention
[0003] The purpose of the utility model is to provide an electrical connection structure for a toner cartridge of a selenium drum, so as to solve the problems of complex structure and difficult assembly of the electrical connection mechanism in the existing toner cartridge of the selenium drum.
[0004] The utility model provides the following technical solution: An electrical connection and matching structure for a toner cartridge of a selenium drum, including a side cover installed on the toner cartridge, a contact chip, and a matching adjustment mechanism arranged between the side cover and the contact chip. The matching adjustment mechanism includes a matching bracket for loading the contact chip and an elastic arm connected between the matching bracket and the side cover. The contact chip contacts corresponding electrical connection contacts of a printing device to electrically connect the printing device. When the toner cartridge moves relative to the drum frame, the side cover is driven to move. At this time, the elastic arm deforms and twists, so that the matching bracket swings relative to the side cover, thereby keeping the contact chip in contact with the electrical connection contacts to maintain the electrical connection between the toner cartridge and the printing device.
[0005] An electrical connection and fitting structure for a toner cartridge, as described above, further includes a limit and protection mechanism disposed between the fitting adjustment mechanism and the side cover. The limit and protection mechanism includes a correspondingly arranged limit post and a limit groove. The minimum width of the limit groove is greater than the maximum width of the limit post. The relative movement of the side cover and the fitting bracket drives the relative movement of the limit post and the limit groove. The inner wall of the limit groove is used to abut against the limit post to limit the movement of the limit post, thereby restricting the relative movement of the fitting bracket and the side cover.
[0006] An electrical connection and fitting structure for a toner cartridge, as described above, the fitting bracket includes a support and a chip bracket. The chip bracket is detachably connected to the support, and one end of the support away from the chip bracket is connected to the elastic arm.
[0007] An electrical connection and fitting structure for a toner cartridge, as described above, the limit post protrudes from the support and is located between the elastic arm and the chip bracket. The limit groove is formed on the side cover.
[0008] An electrical connection and fitting structure for a toner cartridge, as described above, a plugging mechanism is provided between the chip bracket and the support, so that the chip bracket can be plugged into and unplugged from the support. A chip installation groove is formed on one side of the chip bracket away from the plugging mechanism.
[0009] An electrical connection and fitting structure for a toner cartridge, as described above, a plurality of extrusion ribs protrude from the inner wall of the chip installation groove, and a wire passing opening is formed at the bottom of the chip installation groove.
[0010] An electrical connection and fitting structure for a toner cartridge, as described above, the plugging mechanism includes correspondingly arranged plugging guide posts and plugging guide holes, and correspondingly arranged buckles and card slots.

[0011] An electrical connection and fitting structure for a toner cartridge, as described above, the chip bracket protrudes with a limit abutting portion arranged in a trapezoidal shape beside the chip installation groove.
[0012] An electrical connection and fitting structure for a toner cartridge, as described above, the support, the elastic arm and the side cover are integrally formed.
[0013] Compared with the prior art, the present utility model has the following advantages:
[0014] 1. For the electrical connection and alignment structure of the toner cartridge of the present utility model, a structure with a connecting elastic arm is provided between the alignment bracket for loading the contact chip and the side cover. When the movement of the toner cartridge drives the movement of the side cover, the elastic arm deforms and twists, causing the alignment bracket to swing relative to the side cover, so that the contact chip located on the alignment bracket maintains an electrical connection state with the printing device. At this time, the elastic arm utilizes the inherent toughness of the material to keep the connection between the alignment bracket and the side cover and has a tendency of spring-back and reset. Based on the setting of this structure, it provides a structural basis for the integral molding of the alignment bracket, elastic arm and side cover, simplifies the production cost and assembly cost of the electrical connection and alignment structure parts, and improves the competitiveness of the product in the market.
[0015] 2. For the electrical connection and alignment structure of the toner cartridge of the present utility model, a limit protection mechanism is provided between the alignment adjustment mechanism and the side cover. Specifically, the movement of the limit post is restricted by the limit groove to limit the swinging range of the alignment bracket relative to the side cover, so as to prevent the elastic arm from fatigue fracture due to excessive swinging amplitude of the alignment bracket, and has the effect of protecting parts.

Detailed Embodiment
[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0021] Embodiment 1: Please refer to the attached Figure 1 to the attached Figure 3 , this embodiment provides an electrical connection fitting structure for a toner cartridge, which includes a side cover 1 installed on the toner cartridge, a contact chip 2, and a fitting adjustment mechanism 3 disposed between the side cover 1 and the contact chip 2. The fitting adjustment mechanism 3 includes a fitting bracket 31 for loading the contact chip 2 and an elastic arm 32 connected between the fitting bracket 31 and the side cover 1. The contact chip 2 contacts the corresponding electrical connection contacts of the printing device to electrically connect the printing device. When the toner cartridge moves relative to the drum frame, the side cover 1 is driven to move. At this time, the elastic arm 32 deforms and twists, so that the fitting bracket 31 swings relative to the side cover 1, thereby keeping the contact chip 2 in contact with the electrical connection contacts to maintain the electrical connection between the toner cartridge and the printing device. In the electrical connection fitting structure for the toner cartridge of this embodiment, between the fitting bracket 31 for loading the contact chip 2 and the side cover 1, a structure with a connected elastic arm 32 is adopted. When the movement of the toner cartridge drives the side cover 1 to move, the elastic arm 32 deforms and twists, causing the fitting bracket 31 to swing relative to the side cover 1, so that the contact chip 2 located on the fitting bracket 31 maintains an electrical connection state with the printing device. At this time, the elastic arm 32 utilizes the inherent toughness of the material to keep the connection between the fitting bracket 31 and the side cover 1 and has a tendency to rebound and reset. Based on the setting of this structure, it provides a structural basis for the integrated molding of the fitting bracket 31, the elastic arm 32 and the side cover 1, simplifies the production cost and assembly cost of the electrical connection fitting structure parts, and improves the competitiveness of the product in the market.
[0022] The electrical connection fitting structure further includes a limit protection mechanism 4 disposed between the fitting adjustment mechanism 3 and the side cover 1. The limit protection mechanism 4 includes a corresponding limit post 41 and a limit groove 42. The minimum width of the limit groove 42 is greater than the maximum width of the limit post 41. The relative movement of the side cover 1 and the fitting bracket 31 drives the relative movement of the limit post 41 and the limit groove 42. The inner wall of the limit groove 42 is used to abut against the limit post 41 to limit the movement of the limit post 41, thereby limiting the relative movement of the fitting bracket 31 and the side cover 1. In the electrical connection fitting structure for the toner cartridge of this embodiment, the limit protection mechanism 4 is adopted between the fitting adjustment mechanism 3 and the side cover 1. Specifically, the movement of the limit post 41 is restricted by the limit groove 42 to limit the swinging range of the fitting bracket 31 relative to the side cover 1, so as to prevent the elastic arm 32 from fatigue fracture due to excessive swinging amplitude of the fitting bracket 31, and has the effect of protecting the parts
[0023] The fitting bracket 31 includes a support 311 and a chip bracket 312. The chip bracket 312 is detachably connected to the support 311. One end of the support 311 away from the chip bracket 312 is connected to the elastic arm 32.
[0024] The limiting post 41 protrudes from the support 311 and is located between the elastic arm 32 and the chip support 312. The limiting groove 42 is formed on the side cover 1. Preferably, an insertion mechanism 313 is provided between the chip support 312 and the support 311, so that the chip support 312 can be detachably connected to the support 311. A chip installation groove 3121 is formed on one side of the chip support 312 away from the insertion mechanism 313. Then, a plurality of extrusion ribs 3122 protrude from the inner wall of the chip installation groove 3121, and a wire passing opening 3123 is formed at the bottom of the chip installation groove 3121. During assembly, the wire passing opening 3123 is used for the wire welded to the contact chip 2 to pass through. The contact chip 2 is first installed in the chip installation groove 3121, and then the chip support 312 is inserted and installed on the support 311 through the insertion mechanism 313, which is convenient and fast.
[0025] The insertion mechanism 313 includes correspondingly arranged insertion guide posts 3131 and insertion guide holes 3132, and correspondingly arranged buckles 3133 and clamping grooves 3134. The insertion guide posts 3131 and the buckles 3133 are arranged on the chip support 312, the insertion guide holes 3132 are formed on the support 311, and the clamping grooves 3134 are formed on the inner wall of the insertion guide holes 3132. The arrangement of the buckles 3133 and the clamping grooves 3134 can lock the chip support 312 on the support 311.
[0026] The chip support 312 is provided with a trapezoidal limiting abutting portion 3124 protruding beside the chip installation groove 3121. When the anastomosis support 31 swings, the limiting abutting portion 3124 keeps abutting against the corresponding structure of the printing device to prevent the contact chip 2 from being misaligned.
[0027] The support 311, the elastic arm 32 and the side cover 1 are integrally formed, which is convenient for product production.
