AI Technical Summary

Technical Problem

There are a large number of wire harnesses inside the BDU, which are complicated and cumbersome to assemble, which are very prone to poor problems of misconnection and misconnection, and the wire harness is prone to wear and aging.

Method used

A circuit board is designed, including a board body, a loop structure and a connection point. The loop structure is composed of multiple sets of printing branches. The trace cross-sectional area of ​​each printing branch is between 1mm2 and 2mm2. The connection point is used to connect electrical devices of different specifications.

Benefits of technology

The printing branch realizes the connection between multiple electrical devices, reduces the use of wire harness, saves assembly space, simplifies the assembly process, avoids misconnection and misconnection problems, and improves the heat dissipation effect.

Abstract

The present invention relates to the technical field of BDU, and discloses a battery pack. The circuit board comprises a board body, a loop structure and a connection point. The loop structure is arranged on the board body and has a plurality of groups. Each group of loop structures comprises at least two printed branches. The area A of the wiring cross section of each printed branch meets the requirement of 1 mm 2 ≤A≤2mm 2 The connection points are arranged on the printed branches, and the connection points on at least two printed branches of each loop structure are used to connect electrical components of different specifications. The circuit board provided by the present invention can realize the connection between multiple electrical components through the printed branches, reduce the use of wire harnesses, save assembly space, simplify the assembly process, avoid the occurrence of undesirable problems such as misinterpretation and missing connection, and facilitate the realization of automated production; avoid the wear and aging of the wire harness.
