Abstract

A multicore shielded cable includes a first core wire group composed of a plurality of assembled core wires, a first binding tape wound around an outer circumference of the first core wire group, a first braided shield provided around an outer circumference of the first binding tape, a second binding tape wound around an outer circumference of the first braided shield, a second core wire group composed of a plurality of core wires arranged around an outer circumference of the second binding tape, a third binding tape wound around an outer circumference of the second core wire group, a second braided shield provided around an outer circumference of the third binding tape, and a jacket provided around an outer circumference of the second braided shield.

First claim

What is claimed is:

1. A multicore shielded cable, comprising:
a first core wire group composed of a plurality of assembled core wires;
a first binding tape wound around an outer circumference of the first core wire group;
a first braided shield provided around an outer circumference of the first binding tape;
a second binding tape wound around an outer circumference of the first braided shield;
a second core wire group composed of a plurality of core wires arranged around an outer circumference of the second binding tape;
a third binding tape wound around an outer circumference of the second core wire group;
a second braided shield provided around an outer circumference of the third binding tape; and
a jacket provided around an outer circumference of the second braided shield,
wherein one end of the first core wire group is drawn through a mesh of the second braided shield to the outside such that the multicore shielded cable is branched into a first path including the first core wire group and a second path including the second core wire group.

2. The multicore shielded cable, according to claim 1 ,
wherein in the first core wire group the plurality of assembled core wires are stranded together, and the first binding tape is wound around the outer circumference of the first core wire group in an opposite direction with respect to a stranding direction of the first core wire group.

3. The multicore shielded cable, according to claim 1 ,
wherein in the second core wire group the plurality of core wires are wound helically around the outer circumference of the second binding tape, and the third binding tape is wound around the outer circumference of the second core wire group in an opposite direction with respect to a winding direction of the second core wire group.

4. A method for branching a multicore shielded cable comprising a first core wire group composed of a plurality of assembled core wires, a first binding tape wound around an outer circumference of the first core wire group, a first braided shield provided around an outer circumference of the first binding tape, a second binding tape wound around an outer circumference of the first braided shield, a second core wire group composed of a plurality of core wires arranged around an outer circumference of the second binding tape, a third binding tape wound around an outer circumference of the second core wire group, a second braided shield provided around an outer circumference of the third binding tape, and a jacket provided around an outer circumference of the second braided shield, the method comprising removing the jacket to expose the second braided shield, expand a mesh of the second braided shield, draw the first core wire group through that mesh to the outside, and branch the multicore shielded cable into a first path including the first core wire group and a second path including the second core wire group.

5. The method for branching a multicore shielded cable, according to claim 4 , wherein in the first core wire group the plurality of assembled core wires are stranded together, and the first binding tape is wound around the outer circumference of the first core wire group in an opposite direction with respect to a stranding direction of the first core wire group.

6. The method for branching a multicore shielded cable, according to claim 4 , wherein in the second core wire group the plurality of core wires are wound helically around the outer circumference of the second binding tape, and the third binding tape is wound around the outer circumference of the second core wire group in an opposite direction with respect to a winding direction of the second core wire group.
