Abstract

[Problem] To provide a wire harness allowing a relatively large number of electrical wires to be passed under the floor of a vehicle body.
[Means for Solving Problem]
A wire harness 21 is provided with a plurality of high-voltage electrical wires 22 , a protection member 23 which protects the high-voltage electrical wires 22 , fixed members 24, 25 which fix the wire harness in a vehicle, and a low-voltage electrical wire 26 . The protection member 23 has two protection members for body under floor 29 and a body under floor protection member 30 . The protection members thereof are flat-corrugated tubes. In the two protection members for body under floor protection member 29 , circuits 22 a, 22 b which have the plurality of high-voltage electrical wires 22 are respectively received. Also, in the protection member 30 for body under floor, a circuit 26 a which has the low-voltage electrical wire 26 is received. The two protection members 29 and the protection member 30 are arranged side by side.

First claim

The invention claimed is:

1. A wire harness to be mounted on a vehicle, comprising;
a plurality of electrical wires; and
a plurality of plastic flat-corrugated tubes to be located at a body under floor which is outside of a body frame,
wherein the plurality of the electrical wires are configured to be at least grouped into a first group of wires consisting of high-voltage electrical wires and a second group of wires consisting of low-voltage electrical wires at the body under floor, and separately received in the groups of two or more wires in the corresponding plastic flat-corrugated tubes,
wherein each first and second group of wires includes two or more wires,
wherein the wire harness further includes
a plurality of plastic round-corrugated tubes to be located in a vehicle interior, the entire round-corrugated tube located in the vehicle interior,
a plurality of first fixed members each connecting the flat-corrugated tubes entering one side of the first fixed member with the round-corrugated tube entering an opposite side of the first fixed member, and
a second fixed member provided to the plurality of flat-corrugated tubes to fix the plurality of flat-corrugated tubes to the body under floor,

wherein the wire harness with the first fixed members and the second fixed member is configured to be conveyed in a rolled state, and
wherein the wire harness is configured such that, when the wire harness is mounted to the body under floor, the first and the second groups of wires are aligned in a horizontal direction so that any two wires do not overlap with each other in a vertical direction, and the plurality of flat-corrugated tubes are aligned in a horizontal direction so that any two flat-corrugated tubes do not overlap with each other in a vertical direction and a surface in a cross sectional and longitudinal direction of each of the flat-corrugated tubes opposes a back surface of the floor.

2. The wire harness described in claim 1 , wherein a predetermined space is formed in the adjacent flat-corrugated tube.

3. The wire harness described in claim 1 , wherein a corrugated tube, which is formed at the same height as the flat-corrugated tube or with height lower than thereof and is formed into a cross-section round shape, is combined with the flat-corrugated tube.

4. The wire harness described in claim 2 , wherein a corrugated tube, which is formed at the same height as the flat-corrugated tube or with height lower than thereof and is formed into a cross-section round shape, is combined with the flat-corrugated tube.
