Abstract

Abstract:

In order to simulate the real service conditions and obtain the degradation data of electrical connector,a test rig for in-situ analysis characteristic parameters of electrical connector is designed.The repetitive insertion and withdrawal test and the continuous ohmic heating test could be carried out under the setting temperature,humidity and fretting environment.Meanwhile,the contact resistance,mechanical force,insulation resistance and other characteristic parameters could be recorded simultaneously with the help of designed multi-channel signal measurement and control circuit and programmed software.It is valuable for the recurrence of the failure phenomenon and the study of failure mechanism of electrical connectors.

Key words: electrical connector, electrical contact, in-situ analysis, insertion and extraction force, contact resistance
