Abstract

A composite cable that includes plural cables connectable to respective connection portions arranged on a substrate, and an outer coat that covers the cables, the composite cable including: a position fixation portion, in which the cables are fixed in positions so as to be parallel to one another in a longitudinal direction of the cables; and a twist portion, in which the cables extending from an end portion of the position fixation portion are twisted together, wherein in the position fixation portion, an arrangement pattern of the cables on a cross-section perpendicular to the longitudinal direction of the cables is mirror symmetric to an arrangement pattern of the connection portions.

First claim

What is claimed is:

1. A composite cable that includes a plurality of cables connectable to respective connection portions arranged on a substrate, and an outer coat that covers the cables, the composite cable comprising:
a position fixation portion, in which a gap between each of the cables and the outer coat is fixed by a fixing member so as to prevent positional deviation of each of the cables relative to the outer coat such that the cables are fixed in positions so as to be parallel to one another in a longitudinal direction of the cables; and
a twist portion, in which the cables extending from an end portion of the position fixation portion are twisted together, wherein
in the position fixation portion, an arrangement pattern of the cables on a cross-section perpendicular to the longitudinal direction of the cables is mirror symmetric to an arrangement pattern of the connection portions.

2. The composite cable according to claim 1 , wherein a length of the position fixation portion is shorter than a length of the twist portion.

3. The composite cable according to claim 1 , wherein the outer coat includes an indicator portion indicating the position fixation portion on at least a portion of a surface of the position fixation portion.

4. The composite cable according to claim 1 , wherein the composite cable comprises a plurality of cable groups, each being formed of some of the cables, and
in the twist portion, the cables of each of the cable groups are twisted together and the cable groups are also twisted together.

5. The composite cable according to claim 1 , wherein the cross-sectional shape of the position fixation portion in a plane perpendicular to the longitudinal direction is circular.

6. The composite cable according to claim 5 , wherein the cross-sectional shape the twist portion in the plane perpendicular to the longitudinal direction is circular.

7. The composite cable according to claim 1 , wherein the fixing member is a first fixing member, the composite cable further comprising a second fixing member disposed on an outer periphery of the outer coat at least in the position fixation portion.

8. A method of manufacturing a composite cable that includes a plurality of cables, a connection end portion of each of the cables being connectable to respective connection portions arranged on a substrate, and an outer coat that covers the cables, the method comprising:
a position fixing step including fixing an arrangement pattern of the cables on a cross-section perpendicular to a longitudinal direction of the cables so as to be mirror symmetric to an arrangement pattern of the connection portions while fixing the cables so as to be parallel to one another in a longitudinal direction of the cables by a fixing member that fixes a gap between each of the cables and the outer coat;
a twisting step including twisting the cables extending from an end portion of the position fixation portion together; and
a polishing step of performing polishing treatment on a connection end face of the composite cable in a state that the cables are fixed so as to form connection end faces of the cables including the connection end portions on a same plane.
