Abstract
A waterproof construction of a wire for a motor vehicle, which wire has one or more strands and an insulating coating surrounding the strands and is connected to a nonwatertight terminal including a terminal fixed directly to a body of the motor vehicle and a terminal mounted on a nonwatertight connector, wherein at a portion of the wire between its location connected to the nonwatertight terminal and a first branch point, the insulating coating is removed from the wire so as to expose the strands and waterproof material is filled among the strands such that an insulating and waterproofing coating member is wound around an outer periphery of the waterproof material.
Claims14
A waterproof wiring configuration, comprising:
- a wire having a plurality of strands;
- a first insulating member positioned about first and second portions of said wire, said first and second portions being separated to form an exposed area of said wire;
- a waterproofing compound disposed about a portion of said wire and among said strands in said exposed area, said waterproofing compound filling gaps among individual said strands and covering outer peripheries of said strands;
- and
- a second insulating and waterproofing member disposed about and contacting said waterproofing compound between said first and second portions.
A waterproof construction, comprising:
- a wire having a plurality of strands, an end of said wire connected to a non-watertight terminal, said wire having a branch point;
- a first insulating member disposed about first and second portions of said wire, said first and second portions being separated to form an exposed area of said wire, said exposed area located between said end and said branch point;
- a waterproofing compound disposed about said wire and among said strands in said exposed area, said waterproofing compound filling gaps among individual said strands and covering outer peripheries of said strands;
- and
- a second insulating and waterproofing member disposed about and contacting said waterproofing compound between said first and second portions.
A method for waterproofing a wire, comprising:
- providing a wire having a plurality of strands, and being surrounded by a first insulating material;
- removing at least a portion of said first insulating material to expose said strands within an exposed area;
- applying a first waterproofing material to the exposed strands of said wire and among the exposed strands to cover said plurality of strands in the exposed area, said waterproofing material filling gaps among individual said strands and covering outer peripheries of said strands;
- and
- winding a second insulating and waterproofing material around an outer periphery of and in contact with said first waterproofing material and overlapping said first insulating material.
