Abstract

A harness for a vehicle, configured to be attachable to a vehicle body, includes a cable including a plurality of electric wires, each of which includes a center conductor and an insulation that covers the center conductor, a separator including a paper, a non-woven fabric, or a resin tape that covers and contacts with the plurality of electric wires, and an outer sheath that covers the separator, a rubber member provided along a longitudinal direction of a part of the cable, and a fixing member for attaching the cable to the vehicle body. The fixing member is attached to an outer surface of the outer sheath through the rubber member.

First claim

What is claimed is:

1. A harness for a vehicle, configured to be attachable to a vehicle body, the harness comprising:
a cable comprising a plurality of electric wires, each of which comprises a center conductor and an insulation that covers the center conductor, and an outer sheath that comprises a thermoplastic urethane and covers the plurality of electric wires;
a rubber member provided along a longitudinal direction of a part of the cable, the rubber member including ethylene propylene diene rubber; and
a fixing member for attaching the cable to the vehicle body,
wherein the fixing member is attached to an outer surface of the outer sheath through the rubber member,
wherein the plurality of electric wires includes two first electric wires that are free of a shield conductor and two second electric wires each having a cross-sectional area smaller than a cross-sectional area of each of the two first electric wires,
wherein the two second electric wires are in contact with each other,
wherein a cross-sectional area of the center conductor of the first electric wire is larger than a cross-sectional area of the second electric wire,
wherein the two first electric wires are in contact with each other,
wherein the two second electric wires are collectively covered by an inner sheath together, and
wherein a part of the inner sheath is disposed in a space between the two first electric wires contacting with each other.

2. The harness according to claim 1 , wherein the rubber member comprises a plurality of rubber members provided along the longitudinal direction of the part of the cable,
wherein the fixing member is attached to the outer surface of the outer sheath comprising a thermoplastic urethane through one of the plurality of rubber members comprising ethylene propylene diene rubber, and
wherein the plurality of rubber members are distant from both ends of the outer sheath.

3. The harness according to claim 2 , wherein a part of the plurality of electric wires extends from one of the both ends of the outer sheath in a state where the part of the plurality of electric wires is collectively covered by the inner sheath.

4. The harness according to claim 3 , wherein a sensor head is integrated by a resin mold at an end of the inner sheath.

5. The harness according to claim 2 , wherein the cable further comprises a separator that contacts with the outer sheath.

6. The harness according to claim 1 , wherein a part of the plurality of electric wires extends from an end of the outer sheath in a state where the part of the plurality of electric wires is collectively covered by the inner sheath.

7. The harness according to claim 6 , wherein a sensor head is integrated by a resin mold at an end of the inner sheath.

8. The harness according to claim 7 , wherein the inner sheath and the resin mold are air-tightly integrated.

9. The harness according to claim 6 , wherein the plurality of electric wires is movable in the outer sheath.

10. The harness according to claim 6 , wherein the inner sheath comprises a crosslinked thermoplastic urethane.

11. The harness according to claim 6 , wherein a material of the inner sheath includes a silane coupling agent.

12. The harness according to claim 1 , wherein the cable further comprises a separator that contacts with the outer sheath.

13. The harness according to claim 1 , wherein the plurality of electric wires is movable in the outer sheath.

14. The harness according to claim 1 , wherein the insulation comprises crosslinked polyethylene or a tetrafluoroethylene-ethylene copolymer.

15. The harness according to claim 1 , wherein the inner sheath abuts outer surfaces of the two first electric wires.

16. The harness according to claim 1 , wherein outer surfaces of the two second electric wires abut each other, and
wherein outer surfaces of the two first electric wires abut each other.

17. The harness according to claim 1 , wherein the two second electric wires are positioned on a same side of a straight line connecting between respective centers of the center conductors of the two first electric wires.

18. A harness for a vehicle, configured to be attachable to a vehicle body, the harness comprising:
a cable comprising a plurality of electric wires, each of which comprises a center conductor and an insulation that covers the center conductor, and an outer sheath that comprises a thermoplastic urethane and covers the plurality of electric wires;
a rubber member provided along a longitudinal direction of a part of the cable, the rubber member including ethylene propylene diene rubber; and
a fixing member for attaching the cable to the vehicle body,
wherein the fixing member is attached to an outer surface of the outer sheath through the rubber member,
wherein the plurality of electric wires includes two first electric wires that are free of a shield conductor and two second electric wires each having a cross-sectional area smaller than a cross-sectional area of each of the two first electric wires,
wherein the two second electric wires are in contact with each other,
wherein a cross-sectional area of the center conductor of the first electric wire is larger than a cross-sectional area of the second electric wire,
wherein the two second electric wires are collectively covered by an inner sheath together,
wherein the inner sheath is in contact with the two first electric wires,
wherein the inner sheath is disposed in a space between the two second electric wires, and
wherein the outer sheath is disposed in a space between the two first electric wires and a space between the first electric wires and the inner sheath.
