DRAIN WIRE WATER-CUTOFF METHOD AND DRAIN WIRE WATER-CUT-OFF STRUCTURE OF SHIELDED WIRE

摘要

PROBLEM TO BE SOLVED: To provide a water-cutoff method and structure for a drain wire capable of making a water-cutoff treatment part slim, lowering cost for water-cutoff treatment, and endowed with high shielding performance.;SOLUTION: A drain wire and a core wire are drawn out outside from a peeling end at a tip of the shielded wire, a hot-melt tube is covered on a peeling end side of the drain wire, non-waterproof heat-shrinkable tube is covered on a tip side, and further, a waterproof heat-shrinkable tube is covered at least on a part from a rear end of the non-waterproof heat-shrinkable over to a rear end of the hot-melt tube. Later, the non-waterproof heat-shrinkable tube and the waterproof heat-shrinkable tube are put under heating treatment to be thermally shrunk, and at the same time, a hot-melt with the hot-melt tube dissolved is filled in immersion in strands of the drain wire.;COPYRIGHT: (C)2009,JPO&INPIT
