Description

Technical Field

[0001] The utility model relates to the technical field of carbon powder boxes, in particular to a carbon powder box side cover with an integral injection-molded conductive structure. Background Art

[0002] In traditional printing equipment, the toner cartridge is an important consumable component, and its structural design is directly related to the printing quality and service life. Early toner cartridge conductive side covers mostly adopted a split design, that is, the conductive structure and the side cover body were manufactured separately and then assembled. This method not only increased the production cost, but also may affect the conductivity and overall sealing due to the instability of the assembly process, thereby affecting the printing quality. In addition, the side cover with a split structure is prone to loosening, wear, or poor electrical connection during long-term use, which reduces the user experience. In traditional toner cartridges, the drum core steel shaft connected between the conductive side cover structure and the gear side cover structure of the toner cartridge is not only used to position and install the drum core, but also to charge the drum core. However, the production cost of each entire drum core steel shaft is high, and it is relatively complicated to install, which greatly increases the time cost of toner cartridge assembly.

[0003] Therefore, it is imperative to redesign a toner cartridge side cover with an integral injection-molded conductive structure. Utility Model Content
