【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2mm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 view of the fact that the insertion force and contact resistance caused by the random intercalation phenomenon in the current brush electric contact intercalation process are too large and the controllability is poor, This paper presents an improved scheme of brush electric contact structure based on guide interpolation. The improved structure includes single needle cluster guide structure, docking end face guide structure and pin helical straightening structure. After the brush electrical contact, the insertion force test and contact resistance test of 2mm depth were carried out. The results showed that the brush electric contact structure was improved based on the guide interpolation, and the brush electric contact force, contact resistance range and structure were optimized before the structure was improved. The variance values of the force between the contact and the multiple insertions of the brush are 0.39 / 0. 003, respectively. Before the structural improvement, The deviation value of the contact resistance of the single pair brush to the multiple contact is 0.41g 0.008.The structural improvement design of the brush electric contact based on the guide interpolation provides a reference for the improvement of the brush electrical contact performance and the design of its parameters.
