Two piece male pin terminal

A two piece male pin terminal comprising:

• a contact member that is made from an electrically conductive material and an attachment member made from an electrically conductive material;
• the contact member having a cylindrically shaped solid pin along its forward portion, a solid integral collar defining a radially extending abutment at a midportion, a solid cylindrical shaped clamping portion behind said collar and a flattened rearward end portion;
• the attachment member having a rolled cylindrically shaped attachment portion at its forward end that is clamped around the clamping portion of the contact member and a cable attachment portion at its rear end which receives the flattened rearward end portion of the contact member and which engages a core of a wire cable when the two piece terminal is attached to the cable, the improvement being that the clamping portion of the contact member is swaged to define a depression extending radially inwardly from its outer surface and with the material from the swaged depression forming a post extending radially outwardly of said outer surface of said clamping portion and that the cylindrical attachment portion of the attachment member has a seam along its adjacent edges and a pair of aligned notches which together define a slot for receiving said swaged post when the attachment portion is rolled to a cylindrical shape, said post being coined down to define a flange engaging said cylindrical attachment portion at locations surrounding said slot therein to securely retain said attachment member to said contact member.
