Abstract

A composite cable includes a first twisted-pair wire formed by twisting a pair of first electric wires which each include a first center conductor and a first insulation, a second twisted-pair wire formed by twisting a pair of second electric wires which each include a second center conductor and a second insulation, a pair of third electric wires arranged between the first and second twisted-pair wires, the third electric wires each having a larger outer diameter than the first and second electric wires and including a third center conductor with a larger cross-sectional area than the first and second center conductors and a third insulation, and a tape member spirally wound around an assembled article formed by twisting the first and second twisted-pair wires and the pair of third electric wires together. The twisted-pair wires, the assembled article and the tape member are twisted or wound in a same direction.

First claim

What is claimed is:

1. A composite cable, comprising:
a first twisted-pair wire formed by twisting a pair of first electric wires, the first electric wires each comprising a first center conductor and a first insulation covering the first center conductor;
a second twisted-pair wire formed by twisting a pair of second electric wires, the second electric wires each comprising a second center conductor and a second insulation covering the second center conductor;
a pair of third electric wires each having a larger outer diameter than the first and second electric wires and comprising a third center conductor with a larger cross-sectional area than the first and second center conductors and a third insulation covering the third center conductor; and
a tape member spirally wound around an assembled article that is formed by twisting the first twisted-pair wire, the second twisted-pair wire and the pair of third electric wires together,
wherein the first twisted-pair wires and the second twisted-pair wires are arranged oppositely with respect to a straight line connecting centers of the pair of the third electric wires,
wherein the first and second twisted-pair wires, the assembled article and the tape member are twisted or wound in a same direction.

2. The composite cable according to claim 1 , wherein twist pitches of the two twisted-pair wires are smaller than a twist pitch of the assembled article, and wherein a winding pitch of the tape member is smaller than the twist pitch of the assembled article and is not less than the twist pitches of the two twisted-pair wires.

3. The composite cable according to claim 1 , wherein the tape member is configured such that a surface in contact with the assembled article comprises a non-woven fabric, a paper or a resin layer.

4. The composite cable according to claim 1 , wherein the third electric wire comprises a power line for supplying a drive current to a motor for an electric parking brake mounted on a wheel of a vehicle.

5. The composite cable according to claim 1 , wherein at least one of the two twisted-pair wires comprises a signal line for a sensor mounted on a wheel of a vehicle.

6. The composite cable according to claim 1 ,
wherein the assembled article comprises a plurality of thread-shaped fillers arranged between the first twisted-pair wire, the second twisted-pair wire and the pair of third electric wires, and the tape member,
wherein the plurality of fillers are twisted together with the first twisted-pair wire, the second twisted-pair wire and the pair of third electric wires, and
wherein a twist direction of the plurality of fillers is a same as a twist direction of the assembled article and is a same as a winding direction of the tape member.

7. A composite harness, comprising: the composite cable according to claim 1 ; and a connector attached to at least one of end portions of the first electric wires, of the second electric wires and of the third electric wires.

8. The composite cable according to claim 2 , wherein the tape member is configured such that a surface in contact with the assembled article comprises a non-woven fabric, a paper or a resin layer.

9. The composite cable according to claim 2 , wherein the third electric wire comprises a power line for supplying a drive current to a motor for an electric parking brake mounted on a wheel of a vehicle.

10. The composite cable according to claim 3 , wherein the third electric wire comprises a power line for supplying a drive current to a motor for an electric parking brake mounted on a wheel of a vehicle.

11. The composite cable according to claim 2 , wherein at least one of the two twisted-pair wires comprises a signal line for a sensor mounted on a wheel of a vehicle.

12. The composite cable according to claim 3 , wherein at least one of the two twisted-pair wires comprises a signal line for a sensor mounted on a wheel of a vehicle.

13. The composite cable according to claim 4 , wherein at least one of the two twisted-pair wires comprises a signal line for a sensor mounted on a wheel of a vehicle.

14. The composite cable according to claim 2 ,
wherein the assembled article comprises a plurality of thread-shaped fillers arranged between the first twisted-pair wire, the second twisted-pair wire and the pair of third electric wires, and the tape member,
wherein the plurality of fillers are twisted together with the first twisted-pair wire, the second twisted-pair wire and the pair of third electric wires, and
wherein a twist direction of the plurality of fillers is a same as a twist direction of the assembled article and is a same as a winding direction of the tape member.

15. The composite cable according to claim 3 ,
wherein the assembled article comprises a plurality of thread-shaped fillers arranged between the first twisted-pair wire, the second twisted-pair wire and the pair of third electric wires, and the tape member,
wherein the plurality of fillers are twisted together with the first twisted-pair wire, the second twisted-pair wire and the pair of third electric wires, and
wherein a twist direction of the plurality of fillers is a same as a twist direction of the assembled article and is a same as a winding direction of the tape member.

16. The composite cable according to claim 4 ,
wherein the assembled article comprises a plurality of thread-shaped fillers arranged between the first twisted-pair wire, the second twisted-pair wire and the pair of third electric wires, and the tape member,
wherein the plurality of fillers are twisted together with the first twisted-pair wire, the second twisted-pair wire and the pair of third electric wires, and
wherein a twist direction of the plurality of fillers is a same as a twist direction of the assembled article and is a same as a winding direction of the tape member.

17. The composite cable according to claim 5 ,
wherein the assembled article comprises a plurality of thread-shaped fillers arranged between the first twisted-pair wire, the second twisted-pair wire and the pair of third electric wires, and the tape member,
wherein the plurality of fillers are twisted together with the first twisted-pair wire, the second twisted-pair wire and the pair of third electric wires, and
wherein a twist direction of the plurality of fillers is a same as a twist direction of the assembled article and is a same as a winding direction of the tape member.

18. A composite harness, comprising: the composite cable according to claim 2 ; and a connector attached to at least one of end portions of the first electric wires, of the second electric wires and of the third electric wires.
