Abstract

A housing is provided with an electrical wire drawing path projecting toward outside and causing a plurality of at least one of an electrical wire bundle and the electrical wire to be drawn from inside to outside. The electrical wire drawing path includes a first wall member including two side portions extending in a projecting direction of the electrical wire drawing path, a second wall member disposed to be opposed to the first wall member with an interval, a first side wall member projecting from one side portion in a direction crossing an extending direction of the side portions and toward the second wall member, and a second side wall member projecting from the other side portion in a direction crossing an extending direction of the side portions and toward the second wall member.

First claim

What is claimed is:

1. An electrical connection box comprising:
an electronic component with which an electrical wire is electrically connected; and
an insulating housing storing therein the electronic component and in which at least one of an electrical wire bundle and the electrical wire is routed therein, the electrical wire bundle being formed by bundling a plurality of the electrical wires, wherein
the housing is provided with an electrical wire drawing path projecting toward outside and causing a plurality of at least one of the electrical wire bundle and the electrical wire to be drawn from inside to outside,
the electrical wire drawing path includes a first wall member including two side portions extending in a projecting direction of the electrical wire drawing path, a second wall member disposed to be opposed to the first wall member with an interval, a first side wall member projecting from one side portion of the side portions of the first wall member in a direction crossing an extending direction of the side portion and toward the second wall member, and a second side wall member projecting from the other side portion of the side portions of the first wall member in a direction crossing an extending direction of the side portion and toward the second wall member, and
at least one of the first side wall member and the second side wall member is formed as an elastically deformable member enabling change of volume of an electrical wire routing space surrounded by the first wall member, the second wall member, the first side wall member, and the second side wall member.

2. The electrical connection box according to claim 1 , wherein
a boundary portion between the one side portion of the first wall member and the first side wall member is provided with an elastically deformable portion enabling tilt of the first side wall member with respect to the first wall member.

3. The electrical connection box according to claim 1 , wherein
a boundary portion between the other side portion of the first wall member and the second side wall member is provided with an elastically deformable portion enabling tilt of the second side wall member with respect to the first wall member.

4. The electrical connection box according to claim 2 , wherein
a boundary portion between the other side portion of the first wall member and the second side wall member is provided with an elastically deformable portion enabling tilt of the second side wall member with respect to the first wall member.

5. The electrical connection box according to claim 1 , wherein
an end portion of the electrical wire drawing path on a projecting direction side is provided with an electrical wire drawing port causing a plurality of at least one of the electrical wire bundle and the electrical wire in the electrical wire routing space to be drawn to the outside, and
the electrical wire drawing path is formed such that an interval between an end portion of the first side wall member in a projecting direction thereof and an end portion of the second side wall member in a projecting direction thereof is smaller than an interval between the two side portions of the first wall member, at the electrical wire drawing port.

6. The electrical connection box according to claim 2 , wherein
an end portion of the electrical wire drawing path on a projecting direction side is provided with an electrical wire drawing port causing a plurality of at least one of the electrical wire bundle and the electrical wire in the electrical wire routing space to be drawn to the outside, and
the electrical wire drawing path is formed such that an interval between an end portion of the first side wall member in a projecting direction thereof and an end portion of the second side wall member in a projecting direction thereof is smaller than an interval between the two side portions of the first wall member, at the electrical wire drawing port.

7. The electrical connection box according to claim 3 , wherein
an end portion of the electrical wire drawing path on a projecting direction side is provided with an electrical wire drawing port causing a plurality of at least one of the electrical wire bundle and the electrical wire in the electrical wire routing space to be drawn to the outside, and
the electrical wire drawing path is formed such that an interval between an end portion of the first side wall member in a projecting direction thereof and an end portion of the second side wall member in a projecting direction thereof is smaller than an interval between the two side portions of the first wall member, at the electrical wire drawing port.

8. A wire harness comprising:
an electrical wire;
an electronic component with which an the electrical wires is electrically connected; and
an insulating housing storing therein the electronic component and in which at least one of an electrical wire bundle and the electrical wire is routed therein, the electrical wire bundle being formed by bundling a plurality of the electrical wires, wherein
the housing is provided with an electrical wire drawing path projecting toward outside and causing a plurality of at least one of the electrical wire bundle and the electrical wire to be drawn from inside to outside,
the electrical wire drawing path includes a first wall member including two side portions extending in a projecting direction of the electrical wire drawing path, a second wall member disposed to be opposed to the first wall member with an interval, a first side wall member projecting from one side portion of the side portions of the first wall member in a direction crossing an extending direction of the side portion and toward the second wall member, and a second side wall member projecting from the other side portion of the side portions of the first wall member in a direction crossing an extending direction of the side portion and toward the second wall member, and
at least one of the first side wall member and the second side wall member is formed as an elastically deformable member enabling change of volume of an electrical wire routing space surrounded by the first wall member, the second wall member, the first side wall member, and the second side wall member.
