Article Preview

Usually there is a sliding between the contact surfaces of the connector, while the changes in temperature and humidity environment would affect the resistance of the connector contact materials. This paper studies the complicated effects of environment and sliding on the dynamic resistance of the contacts materials of Pd-Ni plated. Series of inspections and analytical research methods are introduced in this article. The surface morphology of specimens after damp heat cyclic test is observed by stereoscopic microscope and scanning electron microscope (SEM). Chemical constitution was examined by X-ray energy spectrum. The contact resistances were measured under the conditions of damp heat cycle by four-point method. The results show that the temperature and humidity environment and sliding has a more complex and significant impact on the performance of the contact materials than single-factors, and the tests are closer to the real working environment.
