Abstract

[Problem] Provided are a composite cable and a composite harness that allow the improvement of cable termination workability while maintaining the flex resistance.
[Solution] A composite cable 1 is provided with a pair of first electric wires 2 , a twisted pair wire 4 formed by twisting a pair of second electric wires 3 having a smaller outer diameter than the first electric wires 2 and a tape member 6 spirally wound around an assembled article 5 that is formed by twisting the pair of first electric wires 2 and the twisted pair wire 4 together, wherein a twist direction of the twisted pair wire 4 is different from a twist direction of the assembled article 5 , and the twist direction of the assembled article 5 is different from a winding direction of the tape member 6.

First claim

The invention claimed is:

1. A composite cable, comprising:
a pair of first electric wires;
a twisted pair wire formed by twisting a pair of second electric wires having a smaller outer diameter than the first electric wires; and
a tape member spirally wound around an assembled article that is formed by twisting the pair of first electric wires and the twisted pair wire together,
wherein a twist direction of the twisted pair wire is different from a twist direction of the assembled article, and the twist direction of the assembled article is different from a winding direction of the tape member,
wherein a twist pitch of the twisted pair wire is smaller than a twist pitch of the assembled article, and a winding pitch of the tape member is smaller than the twist pitch of the assembled article and is not less than the twist pitch of the twisted pair wire.

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

3. The composite cable according to claim 1 , wherein the first 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.

4. The composite cable according claim 1 , wherein the second electric wire comprises a signal line for a sensor mounted on a wheel of a vehicle.

5. The composite cable according to claim 1 , wherein the assembled article comprises a plurality of thread-like filler materials arranged between the pair of first electric wires the twisted pair wire and the tape member, the plurality of filler materials are twisted together with the pair of first electric wires and the twisted pair wire, and a twist direction of the plurality of filler materials is the same as the twist direction of the assembled article and is different from the winding direction of the tape member.

6. 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 and of the second electric wires.
