Abstract

Technology capable of reducing the number of tubular protective members in a wiring member is provided. The wiring member includes: multiple electric wires that branch into multiple branch lines from a main line at a branch position; a connection component provided at an end portion of a target branch line among the branch lines; and a resin molded body that includes a main body portion and an extending portion. The main body portion covers all of the electric wires at the branch position, and the extending portion extends from the main body portion and covers a portion of the target branch line that is between the main body portion and the connection component.

First claim

The invention claimed is:

1. A wiring member comprising:
a plurality of electric wires that branch from a main line into a plurality of branch lines at a branch position;
a connection component provided at an end portion of a target branch line among the plurality of branch lines; and
a resin molded body that includes a main body portion and an extending portion, the main body portion and the extending portion formed as a unitary piece,
wherein the main body portion covers the plurality of electric wires at the branch position,
the extending portion extends from the main body portion and covers a portion of the target branch line that is between the main body portion and the connection component,
the connection component includes a connector housing in which an end portion of the target branch line is accommodated,
the extending portion having a distal end spaced apart from the connector housing,
the wiring member further comprises a connector cover that covers the distal end of the extending portion to a rear end portion of the connector housing,
the resin molded body is an insert-molded body having the plurality of electric wires as insert parts, and
the connector cover is formed using an elastic material,
wherein the connector housing includes a flange, and wherein the connector cover encloses a surface of the flange that faces the connector housing.

2. The wiring member according to claim 1 , wherein a wall thickness of the extending portion is smaller than a wall thickness of the main body portion.

3. The wiring member according to claim 1 , wherein the target branch line includes a bent portion, and
the extending portion maintains the bent portion in a bent shape.

4. The wiring member according to claim 2 , wherein the target branch line includes a bent portion, and
the extending portion maintains the bent portion in a bent shape.
