AI Technical Summary

Technical Problem

The flexible circuit board used in the power battery pack of new energy vehicles softens and ages due to the heat generated by the battery pack, which affects the service life of the power battery pack.

Method used

A flexible circuit board including a substrate body, a terminal block, a protective frame, an insulating assembly and a clamping positioning assembly is designed. The substrate main body consists of an upper cover film, a copper foil wire, a lower cover film and a reinforcement sheet, and a heat insulation pad and a heat dissipation fin are provided on the outside to prevent heat conduction. The protective frame and the positioning frame are combined with the tightening spring to achieve rapid disassembly and assembly.

Benefits of technology

Through thermal insulation and heat dissipation design, the heat generated by the battery pack is effectively prevented from being transmitted to the flexible circuit board, extending its service life, and achieving the convenience of rapid disassembly and assembly.

Abstract

The utility model discloses a flexible circuit board for a power battery pack of a new energy automobile, relates to the technical field of circuit boards, and solves the problems that the conventional flexible circuit board for the power battery pack of the new energy automobile is easy to soften due to the fact that the battery pack is easy to generate part of heat, the aging of the flexible circuit board is caused, and the service life of the flexible circuit board is prolonged. And the service life of the power battery pack is further influenced. Comprising a wiring board, one end of the wiring board is connected with a substrate main body, the other end of the substrate main body is fixedly connected with a terminal, the substrate main body is composed of an upper covering film, a copper foil wire, a lower covering film and a reinforcing sheet, and six bending grooves are formed in the substrate main body; according to the utility model, heat generated by the battery pack is prevented from being conducted into the substrate main body, the generated heat is dissipated, and the heat dissipation frame is quickly fixed outside the protective frame, so that the substrate main body can be quickly disassembled and assembled.
