Abstract

A vehicle wire harness portion (4) is disposed along a metallic vehicle body reinforcing member (3) installed in a vehicle body, and the vehicle wire harness portion (4) includes an integrated power supply wire portion (20) connected to an in-vehicle battery (6) so as to be capable of constantly applying a current and configured to be capable of applying a downstream load current, and a power distribution portion (21) connected to the integrated power supply wire portion (20).

Claims

1. A vehicle wire harness portion structure, in which a vehicle wire harness portion is disposed along a vehicle body reinforcing member installed in a vehicle body,

wherein the vehicle wire harness portion includes an integrated power supply wire portion connected to an in-vehicle battery so as to be capable of constantly applying a current and configured to be capable of applying a downstream load current, and a power distribution portion connected to the integrated power supply wire portion.

2. The vehicle wire harness portion structure according to claim 1, wherein

the vehicle wire harness portion comprises one main harness portion and a plurality of sub-substrates;

the main harness portion includes the integrated power supply wire portion; and

each of the sub-substrates includes the power distribution portion.

3. The vehicle wire harness portion structure according to claim 2, wherein

all of power transmission paths other than a power transmission path of the main harness portion and power transmission paths between the main harness portion and the sub-substrates are incorporated in the main harness portion to be united.

4. The vehicle wire harness portion structure according to claim 1, wherein

a whole or a part of the vehicle wire harness portion is covered with a shielding device.

5. The vehicle wire harness portion structure according to claim 2, wherein

power transmission paths installed in the main harness portion are sorted into at least three types of a power transmission path for a high current, a power transmission path for a low current, and a power transmission path for a signal;

the power transmission paths in each type are disposed so as to be planar, and form a planar power transmission path group; and

each of the planar power transmission path groups is layered one upon another in a state where each of the planar power transmission path groups is individually covered with a shielding device.

6. The vehicle wire harness portion structure according to claim 5, wherein

the power transmission path includes a magnet wire.

7. A vehicle wire harness portion structure, in which a vehicle wire harness portion having a plurality of power transmission paths is disposed along a vehicle body reinforcing member installed in a vehicle body,

wherein the vehicle wire harness portion is formed as a substrate, and thereby a harness substrate is structured;

and

wherein the harness substrate comprises a main substrate and a sub-substrate which are separately provided from each other.

8. The vehicle wire harness portion structure according to claim 7, wherein

the harness substrate comprises one main substrate and four sub-substrates which are separately provided from each other.

9. The vehicle wire harness portion structure according to claim 7, wherein

at least one of the main substrate and the sub-substrates is covered with a covering device.

10. The vehicle wire harness portion structure according to claim 9, wherein

the covering device includes a metallic case or has a structure covering the at least one of the main substrate and the sub-substrates with the vehicle body reinforcing member.

11. The vehicle wire harness portion structure according to claim 7, wherein

at least one of the main substrate and the sub-substrates is housed in a vehicle body reinforcing member component constituting the vehicle body reinforcing member.

12. The vehicle wire harness portion structure according to claim 7, wherein

an integrated power supply circuit portion is provided in the main substrate;

and

a power supply converting functional portion, an auto fuse portion having an automatically recoverable fuse, and a connecting part are provided in each of the sub-substrates.

13. The vehicle wire harness portion structure according to claim 12, wherein

a conductor configured to be capable of applying a downstream load current is installed as an integrated power supply wire in the integrated power supply circuit portion of the main substrate.

14. The vehicle wire harness portion structure according to claim 13, wherein

all the rest of electric wires which are not formed as the substrate are configured to be incorporated in the main substrate.
