Description

Plastic face lid and battery package Technical Field The utility model relates to the technical field of battery packs, in particular to a plastic surface cover and a battery pack. Background Battery packs, which serve as the core components of energy storage devices, play a critical role in modern technology. The design, manufacture and application of the battery pack relate to a plurality of fields, and as technology development is advanced, the battery pack plays a greater role in future energy and traffic fields by optimizing the structure, improving the performance and enhancing the safety. The power terminal of the battery pack is fixed on the plastic surface cover, but at present, a four-corner riveting stud is usually adopted, and then a fixing mode of screw fixing or a fixing mode of nut fixing is adopted, wherein the former fixing mode has complex process and a large number of parts, the latter fixing mode is easy to loosen in use or transportation, and the product competitiveness is not strong. Disclosure of utility model The present utility model aims to solve at least one of the technical problems existing in the prior art. Therefore, the plastic surface cover provided by the utility model has the advantages of simple process, small number of parts, difficulty in loosening in use or transportation and strong product competitiveness. The utility model further provides a battery pack comprising the plastic surface cover. The plastic surface cover comprises a cover body, a power terminal, a wiring screw and a wiring flange nut, wherein the cover body is provided with a through hole, the power terminal is arranged in the through hole and is integrally injection molded with the cover body, an inner screw thread hole is formed in the upper end of the power terminal, an outer screw thread is arranged in the lower end of the power terminal, the wiring screw is in threaded connection with the inner screw thread hole so as to enable the power terminal to be connected with a power line, and the wiring flange nut is in threaded connection with the outer screw thread so as to enable the power terminal to be connected with an inner copper bar. The plastic surface cover has the advantages that the power terminal is arranged in the through hole and is integrally injection molded with the cover body, so that the fastening strength of the power terminal is guaranteed, the appearance surface is neat, the surface cover does not need to rivet a stud, parts are reduced, the potential looseness hazard of a nut is avoided, the production process is simplified, the cost is reduced, the appearance is beautified, and the competitiveness of a product is improved. According to one embodiment of the utility model, the peripheral wall of the power terminal is knurled. According to one embodiment of the utility model, the power terminal is made of brass H62. According to one embodiment of the utility model, the surface of the power terminal is nickel plated. According to one embodiment of the utility model, the binding screw is made using SWRCH 22A. According to one embodiment of the utility model, the surface of the binding screw is plated with environment-friendly colored zinc. According to one embodiment of the utility model, the terminal flange nut is made of SWRCH 22A. According to one embodiment of the utility model, the surface of the connection flange nut is plated with environment-friendly color zinc. According to one embodiment of the utility model, the cover is made of PC-540.
