Abstract

The high concentration of dust particles in the environment is one of the main causes resulting for electrical contact failure of coaxial connectors. Therefore, it is important to carry out proper methods to predict life time of coaxial connectors. In the life time investigation of coaxial connectors, a model is designed and analyzed. Then conclusions are drawn based on a novel accelerated life test. In this paper, a life time prediction method is proposed based on an 1æm-diameter particle environment for the first time, and at the same time a kind of experiment operating equipment is designed to control the concentration of particles for accelerated testing. The result shows an exponential change in contact resistance of coaxial connectors under 1æm-diameter particle environment. We then establish Inverse Power Law-Weibull model for life time prediction in electrical contact failure and obtain the contact reliability and characteristic life.
