Abstract

An electrical connector including a housing and electrical conductor plating. The housing includes a first member and a second member. The first member is made of plastic and forms at least one first contact receiving channel therein. The second member is attached around the first member, and the first and second members form at least one second contact receiving channel therebetween. The electrical conductor plating is on the first member. The electrical conductor plating includes at least one first section along the at least one first contact receiving channel and at least one second section along an exterior side of the first member at the at least one second contact receiving channel. The first and second sections of the electrical conductor plating are electrically separate from one another.
