Abstract

A terminal-equipped electric wire includes at least one electric wire and a terminal including a wire barrel and installed on the electric wire. The electric wire includes a sheath; a conductor having a covered portion covered by the sheath and an exposed portion exposed due to absence of the sheath over a predetermined length at a part of the electric wire in a longitudinal direction of the electric wire; and a bonded portion formed over a predetermined length at a part of the exposed portion, the bonded portion at which strands of the conductor are bonded. An end of the wire barrel on a sheath side is closer to the sheath than an end of the bonded portion on the sheath side. The wire barrel covers at least a part of the bonded portion.

First claim

What is claimed is:

1. A terminal-equipped electric wire comprising:
at least one electric wire including
a sheath,
a conductor having a covered portion covered by the sheath and an exposed portion exposed due to absence of the sheath over a predetermined length at a part of the electric wire in a longitudinal direction of the electric wire, and
a bonded portion formed over a predetermined length at a part of the exposed portion, the bonded portion at which strands of the conductor are bonded; and

a terminal including a wire barrel and installed on the electric wire, wherein
an end of the wire barrel on a sheath side is closer to the sheath than an end of the bonded portion on the sheath side, and
the wire barrel covers at least a part of the bonded portion.

2. The terminal-equipped electric wire according to claim 1 , wherein
an end portion of the wire barrel on the sheath side comprises a bell mouth portion,
the bell mouth portion comprises a first end on the sheath side and a second end opposite to the first end, and
the second end is closer to the sheath than the end of the bonded portion on the sheath side.

3. The terminal-equipped electric wire according to claim 1 , wherein
the longitudinal direction and a front-rear direction of the wire barrel match with each other, and
the bonded portion is located inside the wire barrel in the front-rear direction.

4. The terminal-equipped electric wire according to claim 1 , wherein
the at least one electric wire comprises electric wires,
the terminal is a single terminal, and
the single terminal is installed on the electric wires.

5. A method of manufacturing a terminal-equipped electric wire, the method comprising:
forming a bonded portion by bonding strands of a conductor at a part of an exposed portion of the conductor in a longitudinal direction of the electric wire, the exposed portion at which the conductor is exposed due to absence of a sheath over a predetermined length at a part of the electric wire in the longitudinal direction; and
after the forming of the bonded portion, installing a terminal having a wire barrel on the electric wire so that the wire barrel covers at least part of the bonded portion wherein an end of the wire barrel located on a sheath side of the electric wire is located closer to the sheath than an end of the bonded portion on the sheath side.

6. The method according to claim 5 , wherein
an end portion of the wire barrel on the sheath side comprises a bell mouth portion,
the bell mouth portion comprises a first end on the sheath side and a second end opposite to the first end, and
the second end is closer to the sheath than the end of the bonded portion on the sheath side.

7. The method according to claim 5 , wherein
the longitudinal direction and a front-rear direction of the wire barrel match with each other, and
the bonded portion is located inside the wire barrel in the front-rear direction.

8. The method according to claim 5 , wherein
the at least one electric wire comprises electric wires,
the terminal is a single terminal, and

the single terminal is installed on the electric wires.
