Title:
CONNECTION METHOD OF CORE WIRE WITH INSULATION COVER USED FOR METALLIC CABLE FOR COMMUNICATION, CORE WIRE CRIMPING METHOD, SPLIT SLEEVE, AND CORE WIRE CONNECTING JIG
Document Type and Number:
Japanese Patent JP3926630
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a connection method of a core wire with an insulation cover used for a metallic cable for communication by which, the contact resistance at a connection part is lowered, the mounting operation is simplified, capable of miniaturizing the connection part after mounting.
SOLUTION: Core wires with an insulation cover 4a, 4b cut into two from which, the insulation cover used for a metallic cable for communication is not removed, is inserted into a split sleeve 1 having a split part, and a core wire crimping part 2, having a plurality of needle-shaped protrusion parts 2c at the side to be crimped to the two pieces of the core wires with the insulation cover 4a, 4b is inserted into the split sleeve 1. The plurality of needle-shaped protrusion parts 2c are made to stick into the insulation cover of the two pieces of core wires with the insulation cover 4a, 4b, and pressed as far as the protrusion part touch the conductive part of the core wire with insulation cover so as to obtain electric conduction.
