摘要: 获取高速连接器关键部位准确的力学性能参数,是开展连接器插拔过程仿真和压接可靠性优化设计的前提。针对某型号鱼眼型高速连接器关键部位的材料开展纳米压痕实验,获取了顺应针和PCB孔镀层的载荷-位移曲线。结合内点罚函数优化算法,采用反演求解的方法得到了顺应针和PCB孔镀层的力学性能参数。建立鱼眼型高速连接器插拔过程的有限元模型,将仿真结果与实验结果进行对比,验证了仿真模型的有效性。对顺应针的几何结构进行参数化表征,通过调整顺应针和PCB孔的几何参数,分析几何参数与插拔力的关系,为鱼眼型高速连接器插拔特性的优化以及可靠性分析提供了参考。

Abstract: Obtaining accurate mechanical performance parameters of the key parts of high-speed connectors is a prerequisite for simulating the connector insertion and removal process of the connector, and optimizing the reliability design of crimping. Nanoindentation experiments are carried out on the materials of the key parts of a certain type of fisheye-type high-speed connector, and the load-displacement curves of the compliant pin and PCB hole plating are obtained. Combined with the optimization algorithm of the interior penalty function, the mechanical performance parameters of the compliant pin and PCB hole plating layer are obtained by inverse solution method. A finite element model of the insertion and removal process of the fisheye-type high-speed connector is established, and the validity of the simulation model is verified by comparing the simulation results with the experimental results. The geometric structure of the compliant pin is parametrically characterized, and the relationship between the geometric parameters and the insertion and extraction force is analyzed by adjusting the geometric parameters of the compliant pin and PCB holes. It provides a reference for the optimization of the insertion and removal characteristics of fisheye-type high-speed connectors and reliability analysis.
