Description

Technical Field

[0001] This utility model relates to a laser printer toner cartridge, and more particularly to an indirect connection structure for the printer toner cartridge chip. Background Technology

[0002] The toner cartridges of ordinary laser printers are removable because this makes maintenance, ink refilling, or cleaning of internal waste paper when a paper jam occurs.

[0003] Each time the toner cartridge is reinserted, the printer identifies and verifies it. Only after successful verification will the printer start and enter the workflow normally. This function relies on the chip circuit on the toner cartridge's side cover and the spring-loaded contact pins inside the printer. When the toner cartridge is inserted into the printer, the spring-loaded contact pins slide past the chip circuit and make contact with the corresponding metal contacts on the chip circuit, thereby connecting the chip circuit with the internal system and enabling identification.

[0004] However, during long-term use, because the metal contacts are only a thin layer of copper plating covering the chip circuit, they are prone to wear, leading to poor contact with the elastic pins. Furthermore, due to the limited space on the chip circuit, the area of ​​the metal contacts is also small. After prolonged use, wear and deformation of the drum unit and the printer's internal tracks, as well as high-temperature deformation, can easily cause misalignment between the elastic pins and the metal contacts. Therefore, the applicant has designed an indirect connection structure for the printer drum chip to solve the above problems. Utility Model Content

[0007] The toner cartridge includes a side cover, on which a chip slot and several conductive sheet supports are provided. The chip circuit is installed in the chip slot, and the conductive components are fixed on the conductive sheet supports.

[0008] The side cover is provided with a partition groove, which penetrates the side wall of the chip slot, and the portion between the partition grooves constitutes the conductive sheet support.

[0009] The conductive sheet support includes a vertical plate and a horizontal plate, wherein the vertical plate is part of the side wall and the horizontal plate is part of the side cover.

[0010] The conductive component includes a contact piece and a connecting pin. The contact piece is fixed on the conductive sheet support, and the connecting pin extends along the conductive sheet support to the bottom of the chip slot and is electrically connected to the chip circuit.

[0011] The conductive sheet support is provided with a locking block, and the contact sheet is provided with an elastic side plate opposite to it. The elastic side plate is provided with a locking hole that can be locked into the locking block.

[0012] The side cover is provided with a positioning groove, and the contact piece is provided with an elastic positioning piece. The elastic positioning piece is located in the positioning groove and abuts against the groove wall.

The first connecting piece is connected to the contact piece, and the second connecting piece is located at the bottom of the chip slot and electrically connected to the chip.

[0026] Reference Figures 1 to 3This utility model discloses an indirect connection structure for a printer drum chip, including a drum and a chip circuit 1 disposed on the drum, and further including several conductive parts 2 fixed on the drum. The conductive parts 2 are electrically connected to the chip circuit 1. In this application, the structure of the chip circuit 1 remains unchanged, only the position on the side cover 3 is changed. The conductive parts 2 are located at the installation position of the metal contacts of the chip circuit 1 in the old structure. Previously, there were four metal contacts, so now there are four conductive parts 2 in this application. The conductive parts 2 are then connected to the corresponding metal contacts to conduct electricity. Thus, when the drum is inserted into the printer, the elastic pin will contact the conductive parts 2 to conduct electricity, and thus indirectly conduct electricity with the corresponding metal contacts. The conductive parts 2 in this application are preferably made of copper sheets, which are not only thick and have a large area, but are also very wear-resistant, thereby avoiding the problems of poor contact and misalignment between the elastic pin and the metal contacts.

[0027] As shown in the figure, the toner cartridge includes a side cover 3, on which a chip slot 4 and several conductive sheet supports 5 are provided. The chip circuit 1 is installed in the chip slot 4, and the conductive element 2 is fixed on the conductive sheet supports 5. The above structure is for the convenience of installing the conductive element 2. As a preferred structure of this application, the conductive element 2 includes a contact 6 and a connecting pin 7. The contact 6 is fixed on the conductive sheet supports 5, and the connecting pin 7 extends along the conductive sheet supports 5 to the bottom of the chip slot 4 and is electrically connected to the chip circuit 1. In this application, the metal contacts of the chip circuit 1 face the bottom of the chip slot 4. In this way, when the chip circuit 1 is fixed, it will naturally press against the connecting pin 7 and make contact to achieve electrical conduction. Therefore, the structure is simple and easy to assemble. As a specific fixing structure, the chip circuit 1 is provided with a connecting hole 8, and the bottom of the chip slot 4 is provided with a connecting screw hole. The screw is fixed to the chip circuit 1 by cooperating with the connecting hole 8 and the connecting screw hole.

[0028] As a specific structure, the conductive sheet support 5 includes a vertical plate and a horizontal plate. The vertical plate is part of the side wall, and the horizontal plate is part of the side cover 3. Therefore, the connecting foot 7 includes a first connecting piece 9 and a second connecting piece 10 arranged perpendicularly to the first connecting piece 9. The first connecting piece 9 is connected to the contact piece 6 and is arranged along the vertical plate. The second connecting piece 10 is located at the bottom of the chip slot 4 and is electrically connected to the chip, while the contact piece 6 is fixed to the horizontal plate.

[0029] As shown in the figure, a locking block 11 is provided on one side of the conductive sheet support 5, and an elastic side plate 12 is provided on the contact piece 6. The elastic side plate 12 is provided with a locking hole 13 that can be locked into the locking block 11. Therefore, the elastic side plate 12 can restrict the position of the contact piece 6. With the locking block 11 for fixation, the contact piece 6 can be installed and fixed. Of course, for fixation, a positioning groove 14 is provided on the side cover 3, and a bent elastic positioning piece 15 is provided on the contact piece 6. The elastic positioning piece 15 is located in the positioning groove 14 and abuts against the groove wall of the positioning groove 14. The elastic positioning piece 15 restricts the other movement directions of the contact piece 6. When it cooperates with the connecting foot 7, it limits the horizontal displacement of the contact piece 6. The cooperation between the locking block 11 and the hole limits the vertical movement direction of the contact piece 6. Moreover, the above structure is simple. The conductive part 2 can be integrally formed by punching and bending. Assembly is also easy and does not require screw fixation.

[0030] As shown in the figure, the side cover 3 is provided with a partition groove 16, which penetrates the side wall of the chip slot 4. The part between the partition grooves 16 constitutes the conductive sheet support 5. This not only avoids the risk of possible contact between the conductive parts 2, but also leaves enough installation space to facilitate the insertion of the elastic side plate 12 and the engagement of the card block 11 with the card hole 13.

[0031] The foregoing has provided a detailed description of an indirect connection structure for a printer drum chip provided by the embodiments of this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
