摘要
本文介绍了电动车高压连接器最近设计的一些内接触结构。一类是双螺旋曲线结构、线簧结构、多孔耐磨结构、片簧接触结构、弹性插孔结构的线接触,另一类是多触点接触环、具有阵列凸点的镂空连接管、新型的圆柱形冠簧直接实现点接触,二者都以降低接触电阻,提高载流能力为目的。弹性高压插头则可以与插座直接形成线性接触,不需要冠簧等中介体。
The inner contact structure of the electric vehicle high-voltage connector is introduced.One kind of structure is the line contact structure,such as double helix curve structure,line spring structure,porous wear-resistant structure,leaf spring contact structure and elastic socket structure.Another kind of structure is point contact,such as multi-contact ring,hollow connecting pipe with array convex points,and new cylindrical crown spring to realize point contact directly.Both of them aim at reducing contact resistance and improving current carrying capacity.Elastic high-pressure plugs can directly form linear contact with sockets,without the need for intermediaries such as crown springs.
