摘要：

利用ANSYS对某型号电连接器接触件应力场进行分析，以寻找应力变化规律.对接触件应力场分布特点、插孔形变、接触压力随温度升高的变化规律进行了仿真研究，并进行数据分析与接触压力的试验验证.结果表明：随着温度升高，插孔最大形变量增加，最大接触压力和接触压力区域都有所减少；尺寸较小的接触件插孔槽缝底部最大等效应力随温度升高增幅较大，交变载荷作用时易出现疲劳、破裂等，属产品失效薄弱点.通过分析得知最大等效应力值随温度上升而变化的趋势取决于温度软化效应和热应力增强作用的综合结果；仿真结果能较好地反映电连接器的工作应力状态，接触压力试验验证了有限元仿真方法的可行性.

Abstract:

The stress analysis of contact stress field for a certain type of electrical connectors was carried out to find the law of stress change by using ANSYS. The numerical analysis was performed, which mainly included the stress field distribution,deformation of jacks and the change of contact force between pins and jacks with the temperature increase. Finally the experimental verification and the data analysis were done. The results showed that as the temperature increased,the maximum deformation increased,the maximum contact force and the contact areas were reduced. For small size jacks,the maximum equivalent stress at the slot bottom increased considerably with temperature rising,thus the phenomenon of fatigue or rupture was likely to occur under the alternating load conditions. Through the analysis, it is known that the change of the maximum equivalent stress is determined by the combined results of temperature softening effect and thermal stress enhancement. The feasibility of the proposed method is verified by contact pressure test, and it is a better method to study the working stress of electrical connectors.
Key words: electrical connector    contact    stress field    deformation    contact force    finite element analysis
