Electrical connectors

Abstract

This invention discloses an electrical connector comprising a housing and a plurality of wafers. Each wafer includes two anti-misalignment components disposed on two opposing side faces of a molded part. Each anti-misalignment component includes a main step portion for insertion into a corresponding rectangular through-hole formed in the housing. The main step portion includes an elongated main step portion body, a first protrusion formed at the front end of the main step portion body, and a second protrusion formed at the rear end of the main step portion body. The first and second protrusions protrude opposite to each other. After the main step portion is inserted into the corresponding rectangular through-hole, the front end of the main step portion body abuts against one short side of the rectangular through-hole, the first protrusion abuts against one long side of the rectangular through-hole, and the second protrusion abuts against the other short and long sides of the rectangular through-hole. This electrical connector can prevent misalignment of the molded part during terminal assembly, thus preventing poor terminal contact and improving the signal transmission quality of the electrical connector.
