Title:
WATERPROOF STRUCTURE OF WIRING HARNESS
Document Type and Number:
Japanese Patent JP2016163509
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a waterproof structure of a wiring harness, capable of visually confirming a filling state of a water cutoff agent from an outer part, surely filling the water cutoff agent into a surround of a splice part, and discharging water even when the water enters to a non-filling region.SOLUTION: A waterproof structure of a wiring harness comprises: electric wires 1 and 2 forming an intermediate splice part 3; an exterior member 5 surrounding the intermediate splice part 3 and a plurality of adjacent end parts 12a, 12b, and 22a adjacent to the intermediate splice part 3 in a whole circumference; and a hardening layer 40 of a water cutoff agent filled between the intermediate splice part 3 and the exterior member 5. The exterior member 5 is formed by a waterproofness sheet material 50 curving so as to surround the splice part 3 and the adjacent end parts 12a, 12b, and 22a. The sheet material 50 allows a part 41 of the hardening layer 40 of the water cutoff agent to be wept in a water cutoff agent filling region so as to be dotted on an outer surface 52, and has a plurality of weeping holes 51 opening so as to discharge a moisture content to the outer surface 52 in a water cutoff agent non-filling region.SELECTED DRAWING: Figure 1
