接触件结构参数对连接器插拔特性的影响分析

Research on Influence of Structural Parameters of Contacts on the Insertion-Extraction Characteristics of Connectors

在航空航天、国防等不同系统中,电连接器都发挥着至关重要的作用。这里对某型号电连接器的插拔特性进行研究。通过仿真和正交试验,分析不同的结构参数和材料对该特性的影响。仿真结果表明:插孔簧片的开槽宽度对电连接器性能影响最小,一般不考虑;而簧片的长度、缩口量和簧片厚度均对连接器的接触性能有不同程度的影响;铍青铜触头材料的整体性能优于其他两种材料(锡青铜和黄铜);另外,用圆角槽底代替直角槽底后,三种材料的最大等效应力减小约23%,最大插入力和接触压力都略有增加(约2.17%,3.2%),槽底应力集中的现象得到较大改善。

Electrical connectors are critical components in many applications.The insertion-extraction characteristic of a certain type of electrical connector was studied in it.Through simulation and orthogonal text,the influence of different structural parameters and materials of the contacts on this characteristic was analyzed.And the simulation results showed that the groove width of the socket spring had the least effect on the performance of electrical connectors,and it was almost negligible.The amount of shrinkage,the length and the thickness of the spring had different effects on the performance of electrical connectors.The overall performance of the beryllium bronze contact material was better than the other two materials.In addition,after the flat groove bottom was replaced by the circle groove bottom,the maximum equivalent stress of the three materials was reduced by about 23%,and the maximum insertion force and contact force were slightly increased(about 2.17%,3.2%),the phenomenon of stress concentration at the groove bottom was greatly improved.
