Abstract

A conduction path ( 20 ) is formed by connecting a coated wire ( 26 ), in which a conductor ( 27 ) is surrounded by an insulation coating ( 28 ), to a rear end part of a terminal fitting ( 21 ) and the entire terminal fitting ( 21 ) and a front end part of the coated wire ( 26 ) are to be accommodated into a housing ( 10 ). The conduction path ( 20 ) includes a coating layer ( 29 ) made of a photocurable resin, provided in an area of the coated wire ( 26 ) to be accommodated into the housing ( 10 ), thinner than the insulation coating ( 28 ) and surrounding an area of the conductor ( 27 ) where the insulation coating ( 28 ) is removed.

First claim

The invention claimed is:

1. A conduction path to be accommodated into a housing, comprising:
a wire having opposite first and second ends, a conductor extending from the first end to the second end, an insulation coating surrounding the conductor from a first location spaced from the first end toward the second end, a coating layer made of a photocurable resin surrounding the conductor from the first location to a second location between the first location and the first end, the coating layer being thinner than the insulation coating; and
a terminal fitting having a wire barrel surrounding at least part of the conductor between the coating layer and the first end, and an insulation barrel surrounding at least part of the coating layer at a position spaced from the insulation coating; wherein:
the portions of the terminal fitting surrounding the wire and the portion of the wire having the coating layer thereon are dimensioned to be accommodated in the housing.

2. The conduction path of claim 1 , wherein the coating layer has a higher rigidity than the insulation coating.

3. The conduction path of claim 2 , wherein the coating layer is made of an ultraviolet curable resin.

4. The conduction path according of claim 3 , wherein the coating layer is fixed to an outer periphery of the conductor by molding.

5. A connector, comprising:
a wire having opposite first and second ends, a conductor extending from the first end to the second end, an insulation coating surrounding the conductor from a first location spaced from the first end toward the second end, a coating layer made of a photocurable resin surrounding the conductor from the first location to a second location between the first location and the first end, the coating layer being thinner than the insulation coating; and
a terminal fitting having a wire barrel surrounding at least part of the conductor between the coating layer and the first end, and an insulation barrel surrounding at least part of the coating layer at a position spaced from the insulation coating; and
a housing having a cavity formed therein, the wire barrel, the insulation barrel and at least part of the wire between the insulation barrel and the insulation coating being accommodated in the cavity of the housing.

6. The connector of claim 5 , wherein the coating layer is made of an ultraviolet curable resin.

7. The connector of claim 5 , wherein the coating layer is fixed to an outer periphery of the conductor by molding.
