Improved two piece male pin terminal connector

摘要

A two-piece male pin terminal connector for mechanically and electrically connecting an insulated electrical cable having a conductor core to a terminal cavity is provided. The connector includes an electrically conductive contact member having an elongated cylindrically shaped pin formed along a forward portion of the contact member and a flattened portion formed at a rearward portion of the contact member. The flattened portion has a slightly arcuate shape for establishing electrical contact between the contact member and the conductor core in the insulated electrical cable. The flattened portion further includes a plurality of transversely extending grooves on an upper surface thereof and a plurality of transversely extending ribs on a lower surface thereof. The pin further includes a first clamping portion adjacent the flattened portion which includes at least one annular groove. The connector further includes an electrically conductive crimp saddle attachment member formed from a sheet metal blank. The attachment member includes a generally rectangular first attachment portion formed at its forward most end for receiving and engaging the first clamping portion of the pin. The first attachment portion includes at least one transversely extending rib for engaging the at least one annular groove in the first clamping portion wherein the first attachment portion is tightly rolled and formed into a generally cylindrical shape around the first clamping portion so as to secure the contact member to the attachment member. The attachment member further includes a generally rectangular core crimp portion which is fashioned to form an open generally U-shaped channel for receiving the flattened portion of the contact member and the conductor core of the insulated electrical cable. The core crimp portion further includes a plurality of transversely extending grooves for engaging said plurality of transversely extending ribs on the lower surface of the flattened portion wherein the core crimp portion is crimped onto the conductor core and the flattened portion so as to press the conductor core into the plurality of transversely extending grooves on the upper surface of the flattened portion thereby making electrical connection between the conductor core and the contact member. <IMAGE>
