冲击环境下电连接器接触性能研究
Study on the contact performance of electric connector under impact environment
摘要
Abstract
Impact stress is one of the main environmental factors that affect the contact performance of e-lectrical connectors.In view of the high cost,long consuming time and difficult to implement some high strength environmental tests,the change rules of the contact performance parameters of electrical con-nector contacts under the impact environment are studied by simulation.Based on the basic principles of theoretical mechanics,the physical model of electrical connector contact was established by ANSYS,and the dynamics model was used to simulate the real impact test,the effects of the test severity level,pulse duration and peak acceleration on the deformation,stress and contact force of contacts were analyzed, and some simulation results were verified by test.The results showed that,during the process of impact test,among the contact parameters,the contact deformation was affected most by the impact.The con-tact parameters increased slowly and then increased rapidly with the increase of severity level;and they decreased rapidly and then decreased slowly with the increase of pulse duration;but they were basically stable w hen the peak acceleration changed.It can be seen that the test severity level and pulse duration play dominant roles in the change of contact performance parameters,and the simulation results can pro-vide a theoretical reference for product design.关键词
