## Abstract

A single-core cable is protected over a long region by a pipe. A conductive path includes: a single-core cable in which end portions of a single-core wire are exposed; a first stranded cable in which an end portion of a first stranded wire that is exposed is coaxially fixed to the one end portion of the single-core wire; a second stranded cable in which an end portion of a second stranded wire that is exposed is coaxially fixed to the other end portion of the single-core wire; and a pipe that has an inner diameter dimension capable of surrounding the single-core cable and the first stranded cable, and is axially displaceable between a protective position at which only the single-core cable is surrounded, and an exposed position at which the one end portion of the single-core wire and the first stranded cable are surrounded, and the other end portion of the single-core wire is exposed.

## Claims

### Claim 1

A conductive path comprising:
a single-core cable having a configuration in which a single-core wire is surrounded by a single-core wire insulating covering, and one end portion and another end portion of the single-core wire are exposed by the single-core wire insulating covering being removed;
a first stranded cable having a configuration in which a first stranded wire is surrounded by a first stranded wire insulating covering, and an end portion of the first stranded wire that is exposed by the first stranded wire insulating covering being removed is coaxially fixed to the one end portion of the single-core wire at a first fixed region;
a second stranded cable having a configuration in which a second stranded wire is surrounded by a second stranded wire insulating covering, and an end portion of the second stranded wire that is exposed by the second stranded wire insulating covering being removed is coaxially fixed to the other end portion of the single-core wire at a second fixed region; and
a metal pipe that has an inner diameter dimension capable of surrounding the single-core cable and the first stranded cable, and is axially displaceable between a protective position at which only the single-core cable is surrounded while the first fixed region and the second fixed region are exposed, and an exposed position at which the one end portion of the single-core wire and the first stranded cable are surrounded so as to expose the other end portion of the single-core wire.

### Claim 2 (depends on 1)

The conductive path according to claim 1, wherein
the single-core wire is made of aluminum or an aluminum alloy, and the first stranded wire is made of copper or a copper alloy.

### Claim 3 (depends on 1)

The conductive path according to claim 1, wherein
the one end portion of the single-core wire includes the first fixed region to which the first stranded wire is fixed, and a first exposed portion located between the first fixed region and the single-core wire insulating covering,
the other end portion of the single-core wire includes the second fixed region to which the second stranded wire is fixed, and a second exposed portion located between the second fixed region and the single-core wire insulating covering, and,
in a state in which the metal pipe is at the protective position, only the first fixed region and the second fixed region are exposed to the outside of the metal pipe.

### Claim 4 (depends on 1)

The conductive path according to claim 1, wherein the metal pipe comprises a fixed shape.

### Claim 5 (depends on 1)

The conductive path according to claim 1, wherein the metal pipe comprises a fixed diameter.

### Claim 6 (depends on 1)

The conductive path according to claim 1, wherein the metal pipe comprises a fixed length.
