Abstract

Both deformation of a cross-sectional shape of the entire composite cable and deformation of a cross-sectional shape of an electric wire included in the composite cable are suppressed. The composite cable includes: a plurality of first electric wires; a shield electric wire in which a shield layer 33 is formed around a twist pair wire 32 obtained by intertwining a plurality of second electric wires; a sheath formed around an electric wire assembly obtained by intertwining the first electric wires and the shield electric wire; a first line filler filled between the twist pair wire and the shield layer; and a second line filler filled between the electric wire assembly and the sheath. While the first electric wires and the shield electric wire are intertwined in a first direction, the second electric wires are intertwined in a second direction that is opposite to the first direction.

Claims (16)

1. A composite cable comprising:

a plurality of first electric wires;

a shield electric wire in which a shield layer is formed around a stranded electric wire obtained by intertwining a plurality of second electric wires;

a sheath formed around an assembly obtained by intertwining the plurality of first electric wires and the shield electric wire;

a first line filler filled between the stranded electric wire and the shield layer; and

a second line filler filled between the assembly and the sheath,

wherein the plurality of first electric wires and the shield electric wire are intertwined in a first direction while the plurality of second electric wires included in the shield electric wire are intertwined in a second direction that is opposite to the first direction, and

a filling rate of the first line filler is higher than a filling rate of the second line filler.

2. The composite cable according to claim 1 ,

wherein the second line filler is intertwined in the first direction together with the first electric wires and the shield electric wire, and

the first line filler is intertwined in the second direction together with the second electric wires.

3. The composite cable according to claim 1 ,

wherein the first line filler and the second line filler have the same cross-sectional area as each other, and

the number of the first line filler per unit cross-sectional area is larger than the number of the second line filler per unit cross-sectional area.

4. The composite cable according to claim 1 ,

wherein the first electric wire and the second line filler are directly in contact with each other.
