Abstract

PURPOSE:To surely press-contact a cut piece, by forming a cut piece of a contact wire with a length larger than the diameter and butting it with a cut piece of a noble metal wire, then pressurizing it. CONSTITUTION:A noble metal wire 11 having a circular section is used for the material of a noble metal layer C, and the base material uses a contact wire 11 made of a steel having a smaller diameter than the conventional one. Then both wires 10 and 11 are extruded out of extruding cylinders 2 and 3 in a desired length respectively and cut by cutters 4 and 5. The cut pieces 10a and 11a are put into the storing mold part of a receiving mold 1. Then the 1st punch 5 is hit down to press the upper piece 10a by the punch 6 and an extruding pin 9 to thicken the cut sections to a nearly equal size to temporarily join both cut pieces. After wards, the punch 6 is moved back, and the 2nd punch 7 is actuated to be hit down to the pieces 10a and 11a joined temporarily. At the same time, the pin 9 is pushed up to perform the pressing action to form a head part A and a foot part B. In such way, a composite contact 12 with a thin noble metal layer C is obtained.
