ABSTRACT:
An integral electrical contact (10, 110, 210) and a method for making the electrical contact is disclosed. The contact includes an elongated electrical conducting base portion (19, 119, 219) which has an axial passage (29, 129, 229) extending therethrough and also includes several axially aligned electrical wires (20, 120, 220) integrally formed with the base portion. The wires are axially aligned with the passage of the base portion and extend beyond a first end (18, 118, 218) of the base portion. Each of the wires which extends beyond the first end of the base portion includes an end portion (24, 124, 224) that terminates in an acutely angled surface. The electrical contact is made by coining an electrically conductive flat sheet of material (12) to form a plurality of elongated raised design portions (14, 16, 114, 116, 214, 216) which are axially aligned and extend inwardly from one end surface (13) of the sheet. The design portions are separated by slitting the sheet between the design portions or by further coining the sheet to form the wires. A bevel is placed on the ends of the wires at the end surface of the sheet before the wires are slit apart. The sheet is then rolled so that the wires are axially aligned and adjacent to each other.
