Abstract

A wire harness includes a linear trunk line section formed by bundling a plurality of power supply lines serving as linear wiring bodies wired in a vehicle and a pair of trunk line end distributors each of which is connected to a corresponding one of both ends of the linear trunk line section and distributes electric power from a power supply mounted on the vehicle to each connected appliance, the power supply being connected to at least one end of each of the trunk line end distributors. Thus, with the wire harness, a wiring path can be simplified by combining the linear trunk line section and the pair of trunk line end distributors.

Claims

1. A wire harness comprising:

a linear trunk line section formed by bundling a plurality of power supply lines as linear wiring bodies wired in a vehicle;

a pair of trunk line end distributors, wherein a first trunk line end distributor is connected to a first end of the linear trunk line section, and a second trunk line end distributor is connected to a second end of the linear trunk line section; and

a pair of power supplies, wherein a first power supply is connected to the first trunk line end distributor, and a second power supply is connected to the second trunk line end distributor,

wherein each trunk line end distributor distributes electric power from one of the power supplies to connected appliances.

2. The wire harness according to claim 1, wherein

the linear trunk line section includes a communication line for signal communication serving as a linear wiring body bundled with the power supply lines and wired in the vehicle.

3. The wire harness according to claim 2, wherein

the power supply lines include a power line for power supply and a ground line for grounding.

4. The wire harness according to claim 2, wherein

the trunk line end distributors each include a plurality of divided bodies that are able to be coupled to each other via a coupling unit and are able to be divided from each other via the coupling unit.

5. The wire harness according to claim 1, wherein

the power supply lines include a power line for power supply and a ground line for grounding.

6. The wire harness according to claim 5, wherein

the trunk line end distributors each include a fastened and grounded part that is fastened to the vehicle and grounded.

7. The wire harness according to claim 5, wherein

the trunk line end distributors each include a plurality of divided bodies that are able to be coupled to each other via a coupling unit and are able to be divided from each other via the coupling unit.

8. The wire harness according to claim 1, wherein

the trunk line end distributors each include a fastened and grounded part that is fastened to the vehicle and grounded.

9. The wire harness according to claim 8, wherein

the trunk line end distributors each include a plurality of divided bodies that are able to be coupled to each other via a coupling unit and are able to be divided from each other via the coupling unit.

10. The wire harness according to claim 1, wherein

the trunk line end distributors each include a plurality of divided bodies that are able to be coupled to each other via a coupling unit and are able to be divided from each other via the coupling unit.

11. The wire harness according to claim 1, further comprising a communication line for signal communication serving as a linear wiring body wired in a vehicle separately from the linear trunk line section, wherein

the linear trunk line section is wired on one side of a metal flooring material of the vehicle with respect to a vertical direction, and

the communication line is wired on another side of the flooring material with respect to the vertical direction.

12. The wire harness according to claim 1, wherein

the trunk line end distributors include a plurality of divided bodies that are able to be coupled to each other via a coupling unit and are able to be divided from each other via the coupling unit,

one divided body of the plurality of divided bodies is a first box configured to distribute electric power from the power supply to each connected appliance, and

another divided body of the plurality of divided bodies is a second box configured to distribute electric power from the power supply to each connected appliance.

13. The wire harness according to claim 12, wherein

a power supply system of the first box and a power supply system of the second box are independent of each other,

an appliance related to a safety system of the vehicle is connected to the first box, and

an appliance other than the appliance related to the safety system is connected to the second box.

16. The wire harness according to claim 2, wherein

the trunk line end distributors each include a fastened and grounded part that is fastened to the vehicle and grounded.

14. A wire harness comprising:

a linear trunk line section formed by bundling a plurality of power supply lines as linear wiring bodies wired in a vehicle;

a pair of trunk line end distributors, each of which is connected to a corresponding one of both ends of the linear trunk line section and distributes electric power from a power supply mounted on the vehicle, each power supply being connected to at least one end of each of the trunk line end distributors; and

a communication line for signal communication serving as a linear wiring body wired in the vehicle separately from the linear trunk line section, wherein

the linear trunk line section is wired on one side of a metal flooring material of the vehicle with respect to a vertical direction, and

the communication line is wired on another side of the flooring material with respect to the vertical direction.

15. The wire harness according to claim 14, wherein

the power supply lines include a power line for power supply and a ground line for grounding.

17. The wire harness according to claim 14, wherein

the trunk line end distributors each include a fastened and grounded part that is fastened to the vehicle and grounded.

18. The wire harness according to claim 14, wherein

the trunk line end distributors each include a plurality of divided bodies that are able to be coupled to each other via a coupling unit and are able to be divided from each other via the coupling unit.
