Reliability Study on Terminal Contact Parts of Electrical Connector of JF Series
摘要
Abstract
This paper studies the terminal contact failure of JF series electric connector under random vibration stress,and presents the relative motion state and mechanical model from the failure mechanisms of terminal contact parts.A reliability growth program for electrical connector under random vibration stress is then proposed based on theoretical model analysis and actual failures the mathematical model of insertion and extraction force of terminal parts of JF Series electrical connector is established and analyzed,to determine in the relationship between the variation tendencies of in-sertion and extraction force and other factors.The conclusion that the data range of the terminal compo-nent insertion and extraction force is determined with reference to the relevant manuals where contact failure reduces as the insertion and extraction force increase within the data range is reached.Good correlation be-tween the simulation results and those predicted from the theory models were obtained by establishing simu-lation experiment on the separation process of electric connector contact pair.The finite element simulation model of single pin and sock contact pair is developed, to simulate the dynamic behavior of the contacts,and to obtain the figure of the stress and strain distribution and variation with time for contacts at the time of the maximum and minimum insertion force.关键词
