浅谈几种接触件在新能源汽车高压连接器上的应用

Discussion on the Application of Several Kinds of Contacts in the High Voltage Connector of New Energy Vehicle

连接器是一种借助电信号或光信号和机械力量的作用使电路或光通道接通、断开或转换的功能元件。论文主要就作者所在团队在近几年研发新能源汽车用高压连接器的过程中总结的一些经验进行简述,主要分析了作为连接器核心部件——接触件的材质、性能和结构要求,从影响接触件可靠性的因素等方面对选择接触件进行分析,并以目前作者所接触过的几种接触件为例,说明了选用接触件的原则。

A connector is a functional element that enables the turn on, disconnect, or convert of the circuit or optical channel with the aid of electrical signals or optical signals and mechanical forces. The paper mainly resumes the experience that summarized by the author＇s team in the process of researching and developing high voltage connectors of new energy vehicles in recent years, and mainly analyzes the requirements of material, performance and structure of contacts, which are the core components of connectors. The selection of contacts is analyzed from the aspects that influenced the reliability of contacts. The principle of selecting contacts is illustrated by examples of several kinds of contacts that have been contacted by the author at present.
