Contact resistance investigation of electrical connector with different shrink range

The reliability of electric connection and a stable contact resistance value is usually the most important thing for electrical connector, especially for the electrical connector used in severe environment such as frequently vibration. The present study has investigated the relationship between shrink range and contact resistance of a kind of electrical connector by using the ANSYS software. A indirect coupled structural thermal electrical method was developed to obtain the relations. This paper gives the maximum stress and contact resistance information of connectors in different shrink range value. The contact temperature also was analyzed in this paper.
