摘要：

针对现有毛刷电接触对插合过程中随机插合现象导致的插拔力和接触电阻范围过大、可控性较差的现状,提出基于导向插合的毛刷电接触结构改进方案.改进结构包括单针簇导向结构、对接端面导向结构及插针螺旋校直结构.对改进前、后的毛刷电接触对进行2 mm插拔深度的插拔力试验及接触电阻试验,结果表明:基于导向插合的毛刷电接触结构改进优化了毛刷电接触对插拔力、接触电阻范围,结构改进前、后的单对毛刷接触对多次插拔力方差值分别为0.39,0.003,结构改进前、后的单对毛刷接触对多次接触电阻方差值分别为0.41,0.008.基于导向插合的毛刷电接触对结构改进设计对改善毛刷电接触性能以及其参数设计提供了参考.

Abstract:

In order to solve the problem that the change range of insertion force and the contact resistance of brush electric contact were too large and poor controllability because of the stochastic inserting, the structural improvements based on guiding inserting were proposed. Improved structure included single needle cluster coupling, butt coupling guide structure and single needle cluster spiral straightening. Insertion force and contact resistance test with 2 mm insertion depth for the before and after the improvement of the brush electric contact were carried out, and the results showed that the structural improvements of the brush electrical contact based on guiding inserting optimized the insertion force and contact resistance range of the brush electrical contact, the variance values of insertion force test data of the brush electrical contact for the before and after the structural improvements were 0.39 and 0.003, and the variance values of contact resistance test data of the brush electrical contact for the before and after the structural improvements were 0.41 and 0.008. The brush electrical contact based on guiding inserting can improve the design of the structure, improve the performance of brush electrical contact, and can also provide a certain reference on the parameter design of brush electric contact.
Key words: brush electric contact    guiding inserting    single needle cluster guiding inserting    single needle cluster spiral straightening    electrical connector
