METHOD FOR MANUFACTURING CABLE WITH TERMINAL CLAMPS

摘要

Provided is a method for manufacturing a cable with terminal clamps formed by crimping the barrel portions of the terminal clamps to the core wires of the cable. In the method, before crimping the barrel portions of the terminal clamps to the core wires, a preparatory process is performed in which a mechanical impact is applied to a metal-oxide layer generated on the metal surfaces of the core wires and at least cracks are generated in the metal-oxide layer. This preparatory process makes it possible to expose metal bare surfaces under the metal-oxide layer to the surfaces of the core wires from the gaps between the cracks of the metal-oxide layer. This allows the metal bare surfaces inside the core wires and the terminal clamps to sufficiently contact with each other even if a compression rate in a crimping process of the terminal clamps is reduced. Consequently, the contact resistance between the core wires and the barrel portion can be reduced as compared with a conventional method in which only the crimping process is performed.
