Abstract

Official abstract text for this publication.

A water-stop structure for electrical wire includes: a terminal including an electrical wire connection portion; and an electrical wire in which an outer circumference of a conductor including a plurality of single wires is coated with an insulation coating portion and which is swaged to be fixed to the electrical wire connection portion, a water-stop agent being filled into a gap in the insulation coating portion to thereby perform water stop in the electrical wire. The water-stop agent includes a fluorescent agent.

First claim

Opening claim text (preview).

What is claimed is: 1. A method of manufacturing a water-stop structure for electrical wire including a terminal including an electrical wire connection portion and an electrical wire in which an outer circumference of a conductor including a plurality of single wires is coated with an insulation coating portion and which is swaged to be fixed to the electrical wire connection portion, a water-stop agent being filled into a gap in the insulation coating portion to thereby perform water stop in the electrical wire, the method comprising: a step of dropping the water-stop agent including a fluorescent agent onto an exposed part of the conductor exposed by peeling off the insulation coating portion; a water-stop agent permeating step of generating a pressure difference between an ambient pressure of a part where the water-stop agent is dropped and an inner pressure of the insulation coating portion to thereby pour the water-stop agent into the insulation coating portion; and an inspection step of irradiating the exposed part of the conductor in which the water-stop agent is dropped, with black light, wherein the water-stop agent including the fluorescent agent is a silicone agent hardened with moisture. 2. The method of manufacturing a water-stop structure for electrical wire according to claim 1 , wherein the terminal includes an electrical connection portion, and wherein the electrical connection portion is also irradiated with the black light. 3. A method of manufacturing a water-stop structure for electrical wire including a conductor including a plurality of single wires and an insulation coating portion coating an outer circumference of the conductor, a water-stop agent being filled into a gap in the insulation coating portion to thereby perform water stop in an electrical wire, the method comprising: a step of dropping the water-stop agent including a fluorescent agent onto an exposed part of the conductor exposed by peeling off the insulation coating portion; a water-stop agent permeating step of generating a pressure difference between an ambient pressure of a part where the water-stop agent is dropped and an inner pressure of the insulation coating portion to thereby pour the water-stop agent into the insulation coating portion; and an inspection step of irradiating the exposed part of the conductor in which the water-stop agent is dropped, with the black light, wherein the water-stop agent including the fluorescent agent is a silicone agent hardened with moisture.
