Hollow contact pin with wire wrap terminal and method of making same

Abstract

Abstract There is disclosed a hollow contact pin comprising a tubular section which is open at one end to receive one or more wires and having extending from its closed end and integral therewith a solid elongate conductor polyhedron in cross-section forming a wire wrap terminal. The tubular part may have an inwardly extending finger to grip any wire placed therein. The method disclosed herein includes the steps of drawing a flat strip of wire into tubular form, then swaging the tube to a diameter determined for the socket portion, at the same time swaging a further advanced portion of the tube to reduce the diameter to form a solid circular rod, at the same time at an advanced portion of the workpiece swaging the circular portion to form a wire wrap terminal which is substantially square in crosssection, and at the same time piercing the forward end of the most advanced tubular socket portion to open and flare the same, and finally separating the completed socket pin-wire wrap terminal from that following it. If the socket portion is to be provided with a wire-engaging finger, the flat strip is first lanced at determinate distances before being drawn into tubular form.
