Abstract

An electrical connector includes a dielectric body that has an input end, an opposite output end, and first and second non-insulated conductive members supported by the dielectric body. The first non-insulated conductive member has a first contact end and an opposite first wire connection end. The second non-insulated conductive member has a second contact end and an opposite second wire connection end. Each of the first and second contact ends are proximate the output end of the dielectric body and form a first pair of electrical contacts. Each of the second wire connection ends are proximate the input end of the dielectric body. First and second insulated conductive members are supported by the dielectric body. Each of the first and second insulated conductive members are connected to one of a second pair of electrical contacts, respectively. The first and second pairs of electrical contacts form an array of electrical contacts at the output end of the dielectric body.
