Simulation Study on High Temperature Vibration Failure of Electrical Connector
The dynamic response of electrical connector in high temperature vibration environment is analyzed with Ansys software.The influence of the quality of the cable at the tail of the contact piece,temperature,separation force,stress relaxation,etc.on the micro motion amplitude is deeply analyzed.Based on the simulation,it is concluded that the original design will fail in high temperature vibration.The design of the contact positive pressure and the quality of the tail cable are optimized.Combined with the simulation analysis results and the relevant calculation,the design index range for the electrical connector to not fail under the specified high temperature vibration conditions is obtained,which means that the separation force should be as close as possible to the upper limit of 2.5 N,and the quality of the cable at the tail of each contact should be controlled within 1.2 g.The correctness of the simulation and optimization is verified by the test,which provides the design and optimization ideas for the high temperature vibration resistance of the electrical connector.
