PROBLEM TO BE SOLVED: To improve electrical characteristics at a connection part and efficiency in treatment work, and provide the connection treatment at a low cost. SOLUTION: An insulating unit 3, in which a normal temperature shrinkable type insulating tube is held around a diameter widening and holding member 2 is inserted in an outer boundary side of a cable sheath, before a conductive connection part 8 is formed. One side 2A of the diameter widening and holding member 2a in the insulating unit 3 is fixed to a cable core or a conductor connection part 8. While the insulating unit 3 is moved to the conductive connection part 8, a string-shaped body 2a in the diameter widening and holding member 2 in the insulating unit 3 is untied, and passed through the diameter widening and holding member 2. While the string-shaped body 2a is drawn outwardly on the other end 2B and pulled out, and the diameter widening and holding member 2 is disassembled, the insulating tube is made to shrink into a small diameter and fixed tightly to an outer boundary of a cable connection treatment part, including the conductive connection part 8 to join the cable in treatment work. |
