Description

technical field [0001] The invention relates to the technical field of conductive metal connectors, in particular to an aluminum part for power transmission and a processing technology for obtaining the aluminum part for power transmission. Background technique [0002] With the increasing demand for lightweight wire harnesses, more and more aluminum cables are used in wire harnesses. In order to match different usage environments, aluminum cables in wire harnesses generally use multi-core aluminum conductors. This can make the aluminum cable more flexible and adaptable to different usage and installation environments. In order to achieve a better electrical connection between the aluminum cable and the matching electrical device, before the multi-core aluminum conductor core of the aluminum cable is connected to the same metal or dissimilar metal, the multi-core aluminum conductor core of the aluminum cable is generally used The aluminum conductive device is crimped into a...
