Abstract

A complex harness includes first electric wires, each of which includes a first center conductor and a first insulation that covers the first center conductor, a cable including second electric wires, each of which includes a second center conductor and a second insulation that covers the second center conductor, and an inner sheath that covers the second electric wires, and an outer sheath covering the first electric wires and the cable collectively. The first electric wires are extended from an end of the outer sheath. The cable is extended from the end of the outer sheath in a state where the second electric wires are collectively covered by the inner sheath in such a manner that an extension length of the cable from the end of the outer sheath is greater than an extension length of the first electric wires from the end of the outer sheath.

First claim

What is claimed is:

1. A complex harness, comprising:
two first electric wires contacting with each other, each of which comprises a first center conductor and a first insulation that covers the first center conductor;
a cable comprising two second electric wires contacting with each other, each of which comprises a second center conductor and a second insulation that covers the second center conductor, and an inner sheath that comprises a thermoplastic resin and covers the second electric wires, without being provided with a shield conductor; and
an outer sheath covering the two first electric wires and the cable collectively, wherein the two first electric wires are extended from an end of the outer sheath,
wherein the inner sheath enters between the two second electric wires,
wherein the cable is extended from the end of the outer sheath in a state where the two second electric wires are collectively covered by the inner sheath in such a manner that the cable extends from the end of the outer sheath,
wherein a filler is not provided between the two first electric wires and the cable,
wherein the cable is in contact with the two first electric wires in a state where the cable enters in a valley provided by the two first electric wires contacting with each other,
wherein the outer sheath formed by extrusion molding of a thermoplastic resin enters in a valley provided by the first electric wires and the cable contacting with each other,
wherein, in the inner sheath, the two second electric wires are provided but no optical element is provided, and
wherein an end of the cable is provided with a sensor head integrated with the inner sheath by a resin mold.

2. The complex harness according to claim 1 , wherein each of the two second electric wires has a cross-sectional area smaller than a cross-sectional area of each of the two first electric wires.

3. The complex harness according to claim 2 , wherein the two first electric wires contact with the inner sheath.

4. The complex harness according to claim 1 , wherein the two first electric wires contact with the inner sheath.

5. The harness according to claim 1 , wherein a protector comprising a tube or a hose is provided around an extended part of the two first electric wires extending from the end of the outer sheath, while the protector is absent around an extended part of the cable extending from the end of the outer sheath.

6. A complex harness, comprising:
two first electric wires contacting with each other, each of which comprises a first center conductor and a first insulation that cover the first center conductor;
a cable comprising two second electric wires contacting with each other, each of which comprises a second center conductor and a second insulation that covers the second center conductor, and an inner sheath that comprises a thermoplastic resin and covers the second electric wires, without being provided with a shield conductor; and
an outer sheath covering the two first electric wires and the cable collectively, wherein the two first electric wires are extended from an end of the outer sheath,
wherein the inner sheath enters between the two second electric wires,
wherein the cable is extended from the end of the outer sheath in a state where the two second electric wires are collectively covered by the inner sheath in such a manner that the cable extends from the end of the outer sheath,
wherein the cable is in contact with the two first electric wires in a state where the cable enters in a valley provided by the two first electric wires contacting with each other,
wherein the outer sheath formed by extrusion molding of a thermoplastic resin enters in a valley provided by the first electric wires and the cable contacting with each other, and
wherein an end of the cable is provided with a sensor head integrated with the inner sheath by a resin mold.
