摘要：电连接器是通过压力接触的连接方式，达到顺利的电气接通。为研究电连接器在插拔应力下接触电阻特性，基于接触电阻理论，采用 ANSYS 软件对电连接器进行模拟插拔研究，并采用 COMSOL 软件对接触电阻进行仿真分析。通过实验对比得到电连接器接插件插拔时接触压力与接触电阻呈反比关系，插拔次数与接触电阻基本呈正比关系，但不会在短时间内对接触电阻有较大影响。

Abstract: The electrical connector is connected by pressure contact to achieve a smooth electrical connection. To study the contact resistance characteristics of the electrical connector under plugging stress, ANSYS is used to simulate the plug-in analysis of the electrical connector, and COMSOL is used to simulate the contact resistance based on the contact resistance theory. The result shows that the contact pressure is inversely proportional to the contact resistance when the electrical connector is plugged in and out; the plugging times are proportional to the contact resistance. However, it would not have an obvious impact on the contact resistance in a short time whenever the electrical connector is plugged in and out.

Key words: electrical connector; plugging; contact resistance; simulation analysis
