文章针对电源连接器SJ045-25STH0插头端接触件,分析了接触件在基座中的受力情况,建立了静平衡方程,得出摩擦系数和弹臂高度是影响接触件保持力的关键因素;并针对提出的三种不同弹臂结构,采用有限元法仿真,获得了三种不同弹臂结构的接触件保持力和应力应变情况,确定了直臂凸包结构为较优方案,并通过试验验证了直臂凸包结构的可行性。本文通过仿真与试验研究接触件的保持力,建立了科学的分析过程,为接触件保持力的提升提供设计参考。

Aiming at plug end contact of the SJ045 -25STH0 power connector, by analyzing the force condition of the contact element in the base and the establishing the static balance equation, it is concluded that the friction coefficient and the height of the elastic arm are the key factors influencing the holding force of the contact. According to the three different elastic arm structure, using the finite element method simulation, the contact holding force , stress and strain of three different elastic arm structure are obtained and the convex hull arm structure is determined to be optimum solutions by experimental verification. In this paper, through the simulation and experimental research of the contact holding force, the scientific...
