Abstract: A harness cable connector is shown which receives a plurality of insulated wires by a press fit for retaining the wires in a spaced configuration during insertion and assembly of the wires in a printed circuit board. The cable connector is then rolled and locked into the printed circuit board to provide strain relief for the harness cable.

Abstract: A miniature electrical connector is shown having an insulated housing with a bore passing therethrough including a large passageway and a reduced passageway joined by an inwardly tapering surface. A contact is received by the passageway having three uniformly spaced, triangular based protrusions whose sides form a sharp tapered edge which tapers at a greater angle than the inwardly tapered surface of the passage for engaging that surface as the contact is inserted therein. The contact is provided with leaf spring latches which snap outwardly once beyond the reduced portion of the passageway to prevent the unauthorized removal of the contact therefrom. The uniformly spaced protrusions having sharp edges tapering at a greater angle than the inwardly tapering surface of the passage cause the contact to be self-centering while stably retaining the contact within the passageway.

Abstract: A multi-wire wiper contact is shown formed from a plurality of conductive and nonconductive wires wrapped about a mandrel to form a flat set of wires helically wrapped into a coil. The wire coil is then masked with a desired pattern and the unmasked wire is plated with a conductive metal. The metal plate which forms on the unmasked portions of the wire does not form on those unmasked wires which are nonconductive. After plating, the masking is removed, one set of wire is cut, and the wire set and plated portions holding that set are removed from the mandrel in a continuous flat strand of wire with the nonconductive wire forming a parting line for the strand. The nonconductive wire is removed from the strand and the strand is then cut and shaped into a multi-wire wiper contact for use in potentiometers and other electromechanical devices.
