Problems solved by technology

[0005] There are many faults in the use of electric vehicles, which lead to a reduction in the service life of electric vehicles, a large amount of waste materials, pollution of the environment, and waste of resources
For example, when an electric vehicle suddenly loses power and cannot drive, it may be due to a fault in a certain wiring harness of the electric vehicle, and there may be a situation where the terminal is oxidized and loses conductivity. In order to solve this type of problem, It is necessary to find a terminal with high conductivity and oxidation resistance from the source of the terminal preparation material

Abstract

The invention belongs to the field of wire harness materials of electric vehicles, and provides a novel antioxidant high-conductivity electric vehicle wire harness and a preparation method thereof. The wire harness comprises a copper wire, a connecting terminal and a wire pipe. Wherein the copper wire is made of a copper alloy composite material; wherein the terminal is prepared from a copper-based metal material, and the wire tube comprises a PVP composite wire protection tube. The wire harness is specifically prepared by the following method: wrapping a copper wire with a PVP composite wireprotection tube, and then welding the copper wire in a terminal by using a welding technology, so that the copper wire is connected with the terminal, and finally, the electric vehicle wire harness isobtained. The raw materials are simple, and the prepared wire harness is good in conductivity, high in oxidation resistance and stable in performance.

Description

technical field [0001] The invention belongs to the field of wire harness materials for electric vehicles, and in particular relates to a novel anti-oxidation and high-conductivity electric vehicle wire harness and a preparation method thereof. Background technique [0002] The electric vehicle cable belongs to the core component of the entire electric vehicle, which is equivalent to the blood vessel of an electric vehicle. Through these electric beams, the power of the battery is output to the motor, control system, lighting system, and auxiliary system, so as to drive the electric vehicle forward and backward. Purpose. The carrier of the entire electric vehicle line is the electric vehicle wiring harness.
