Description

Plastic wiring bin cover plate suitable for energy storage battery pack Technical Field The utility model relates to the technical field of battery packs, in particular to a plastic wiring bin cover plate suitable for an energy storage battery pack. Background With the popularization of renewable energy sources, the new energy storage industry is continuously developed, and a battery pack is gradually flushed into a household for use, so that potential hazards are brought, and the safety of products is required to be continuously improved. The existing battery pack generally exposes output positive and negative terminals directly outside, such as misoperation (false touch by children), directly contacts conductive foreign matters with positive and negative terminals, directly causes short circuit, endangers personal safety, and aims at the phenomenon in some countries, relevant safety requirements are customized (the output positive and negative terminals cannot be directly exposed outside), so that potential safety hazards exist in the use of the battery pack, and on the other hand, terminal aging can be accelerated under severe environment (insolation), the overcurrent capacity of the terminals is reduced, and the overall performance of products is influenced. Therefore, a wiring bin scheme is designed in the market, and the principle is that a sheet metal wiring bin cover plate is adopted to independently make a space for isolating an output positive terminal, a negative terminal, a communication terminal, a dial number and the like from the outside into a wiring bin, so that the design increases the manufacturing cost of a product, occupies the internal space of the product, increases the whole volume and influences the appearance of the product. Disclosure of utility model In order to solve the problems, the technical scheme is that the plastic wiring bin cover plate suitable for the energy storage battery pack comprises a battery pack body, a cover plate, fixing screws and three limit screws; The upper right corner of the battery pack body is provided with a wiring bin, three limit screws are arranged on one surface of the wiring bin, three connecting positions are arranged on the cover plate, and each limit screw is movably positioned in one connecting position; The wiring bin is provided with a first screw hole, the cover plate is provided with a second screw hole, and the fixing screw part penetrates through the second screw hole and is in threaded connection with the first screw hole. Further, the cover plate is made of ABS+PC, and the thermal deformation temperature of the cover plate can reach 80 ℃. Further, the inner side of the cover plate is provided with criss-cross reinforcing ribs, and the reinforcing ribs are used for improving the strength of the cover plate. Further, each connecting part is provided with a buckling groove, two external sides of each buckling groove are respectively provided with a chamfer, and two chamfers are correspondingly arranged.
