Multi-core cable and its manufacturing method

摘要

There is provided a multi-core cable including: first insulated wires; second insulated wires; coaxial wire pairs; and a sheath. The second insulated wires are smaller in diameter than the first insulated wires. The coaxial wire pairs are provided in an even number of pairs. The first insulated wires and the coaxial wire pairs are arranged close to each other on a single circle in a cross section, and the second insulated wires are disposed thereinside. The first insulated wires, the second insulated wires and the coaxial wire pairs are wholly twisted, and then, wholly covered by the sheath.

1. A multi-core cable comprising:
first insulated wires; second insulated wires which are smaller in diameter than the first insulated wires; coaxial wire pairs including an even number of pairs of coaxial wires; and a sheath which wholly covers the first insulated wires, the second insulated wires and the coaxial wire pairs, wherein each of the first insulated wires consists of a conductor being twisted wires and a sheath covering the conductor, wherein the first insulated wires and the coaxial wire pairs are arranged close to each other on a single circle in a cross section taken perpendicularly to a cable longitudinal direction of the multi-core cable, wherein the second insulated wires are disposed inside the circular arrangement of the first insulated wires and the coaxial wire pairs, wherein the first insulated wires, the second insulated wires and the coaxial wire pairs are wholly twisted, and wherein a space between the coaxial wire pairs, the first insulated wires and the second insulated wires are filled with a tension member.
