摘要： PURPOSE:To bind insulating wires safely by bending a belt-formed thin plate into U-shape, inserting plural insulating wires inside the U-shape, and imposing a pressure to the wires from the opening side. CONSTITUTION:In a calking jig 3 which consists of an upper pattern 3a and the lower pattern 3b, a pressing rod 3a-1 buffed with a compressive spring 3a-2 inside the upper pattern 3a is arranged being hung at the center position of calking movable in the direction of the calking. By using a calking jig 3 which has recesses 3c in the form to calk a binding ring 1 in a ring form by combining the upper and the lower patterns 3a and 3b, and the binding ring 1, plural insulating wires are bound into a single line. Consequently, the pressing rod 3a-1 which is buffed by the compressive spring 3a-2 can impose a constant pressure to the insulating wires 2 in the process of calking until the U-shaped opening is closed, and the insulating wires 2 are prevented from pinching partially or swelling out.

CONSTITUTION:Plural pieces of contact springs 1 are aligned regularly, while the one end is formed in the form connected to a connecting part solidly with plastics, and an electrical conducting part 3 to be reached to the connecting part 2 is formed on one side of the spring 1. At time of its formation, a conductive pattern is formed in advance on a film base with a conductive material, then the film base is set in the inner part of a forming die and, after resin is poured and formed, the film base is separated from the molding. And, in the film base, anticorrosive metallic foil of Au plating or the like is formed in its part corresponding to a contact part 3a of the spring in advance and such one subjected to treatment for ease of soldering or the like in a connecting tab part 3b, respectively, and these parts are set up so as to correspond to each contact spring. With this constitution, reduction in manufacturing cost is contrivable.
