Abstract: An electrical connector comprises matable housing members and contact-carrying inserts. Matable electrical contact members are secured in passageways in each of the inserts and a coupling member holds the housing members, contact-carrying inserts, and electrical contact members in matable engagement. The housing members and the contact-carrying inserts include projections and flexible latching members to latchably secure the contact-carrying inserts in polarized positions in the housing members for proper matable engagement with each other. According to another aspect of the present invention, the flexible latching members including the polarizing areas of the contact-carrying inserts can be oriented relative to their respective housing members by angular selection to assure mating engagement between only these housing members and inserts so that proper electrical interconnection is made between electrical circuits.
