摘要
为了优化电连接器的设计,针对电连接器悬臂弹舌式接触件进行插拔过程分析,建立插拔力和接触压力的理论模型。利用ABAQUS软件对接触件的插拔过程进行有限元仿真,研究了各参数对插拔力和稳定接通状态的接触压力的影响。通过接触件的插拔实验验证了理论模型和仿真分析的准确性。结果表明:最大插拔力随着摩擦系数μ、弹舌倾角α_0。和初始接触点至最高点距离H_3增大而增大,随插头端子与插座端子的间隙H_2增大而减小;稳定接通状态的接触压力随参数α_0、H_3增大而增大,随H_2增大而减小。
In order to optimize the design of electric connector, the insertion-withdrawal process of contacts for the elastic cantilever type electrical connector was studied in this paper, and theoretical models for insertion-withdrawal force and contact pressure were established. Simulation was accomplished by ABAQUS, which was used to research insertion-withdrawal process of electrical connector contacts. And then, the influence of each parameter for the insertion-withdrawal force and the contact pressure of the steady link state were researched. By the insertion- withdrawal test, we verified the accuracy of the theoretical model and the simulation. The results showed that the maximum insertion-withdrawal force increases with increasing friction coefficientμ, angle of spring tongue α0 and a distance H3 form the initial contact point to the highest point, on the contrary, it decreases with increasing a gap H2 between the plug terminal and the socket terminal. The contact pressure in the steady link state increases with increasing parameter α0 , H3 , on the contrary, it decreases with increasing parameter H2.
