Abstract

An electric wire protection member that prevents a connector or a terminal portion from coming into contact with water due to water intruding into a grommet. The electrical wire protection member disclosed by this specification includes a tube-shaped corrugated tube that protects electrical wires; a tube-shaped grommet that has a connection tube portion for connection to an opening end portion of the corrugated tube, and protects the electrical wires in place of the corrugated tube; a tube-shaped holder that has a mating tube portion that is fitted into the connection tube portion of the grommet, and abuts against the opening end portion of the corrugated tube; and a rubber stopper that has electrical wire sealing holes into which the electrical wires are inserted in a sealed state, and that comes into close contact with the inner peripheral surface of the holder.

First claim

1 . An electrical wire protection member comprising:
a tube-shaped corrugated tube capable of protecting an electrical wire; a tube-shaped grommet that has a connection tube portion for connection to an opening end portion of the corrugated tube, and is capable of protecting the electrical wire in place of the corrugated tube; a tube-shaped holder that has a mating tube portion that is fitted into the connection tube portion of the grommet, and abuts against the opening end portion of the corrugated tube; and a rubber stopper that has an electrical wire sealing hole into which the electrical wire is inserted in a sealed state, and comes into close contact with an inner peripheral surface of the holder.

2 . The electrical wire protection member according to claim 1 , wherein the holder is an integrated holder, and a tapered insertion guiding surface is provided in an opening edge portion on a corrugated tube side of the holder.

3 . The electrical wire protection member according to claim 2 , wherein the rubber stopper is housed inside the mating tube portion of the holder.

4 . The electrical wire protection member according to claim 2 , wherein the rubber stopper is housed inside a flange portion provided on a base end side of the mating tube portion of the holder.

5 . The electrical wire protection member according to claim 1 ,
wherein the rubber stopper is housed inside a flange portion provided on a base end side of the mating tube portion of the holder, and the holder includes a pair of divided holders and a lock portion that holds the pair of divided holders in a state of being assembled to each other.
