Abstract

A terminal-equipped wire configured by crimping a pair of barrel pieces provided on a terminal to an external sheath of a wire, the external sheath being provided on an outer circumferential surface of a core wire. The pair of barrel pieces are wrapped around the external sheath into a polygonal tube shape that has a plurality of corner portions in a circumferential direction of the external sheath, leading end edges of the pair of barrel pieces are arranged on opposite sides of at least one corner portion out of the plurality of corner portions.

First claim

The invention claimed is:

1. A terminal-equipped wire configured by crimping a pair of barrel pieces provided on a terminal to an external sheath of a wire, the external sheath being provided on an outer circumferential surface of a core wire,
the pair of barrel pieces are wrapped around the external sheath into a polygonal tube shape that has a plurality of corner portions in a circumferential direction of the external sheath, and
leading end edges of the pair of barrel pieces are arranged on opposite sides of at least one corner portion out of the plurality of corner portions,
wherein mutually matching abutting edge portions of the pair of barrel pieces have an uneven shape on a leading end side in an extension direction of the pair of barrel pieces,
wherein an outer barrel is crimped to the pair of barrel pieces from the outside,
wherein a pair of leading end edges of the outer barrel are arranged on opposite sides of at least one corner portion out of the plurality of the corner portions, and
wherein the abutting edge portions of the pair of barrel pieces and the pair of leading end edges of the outer barrel are arranged at different positions in a circumferential direction of the wire.

2. The terminal-equipped wire according to claim 1 ,
wherein the wire includes a shield layer between the core wire and the external sheath,
the shield layer is exposed at an end of the wire and folded back onto an outer circumferential surface of the external sheath, and
the pair of barrel pieces are crimped to the external sheath via the shield layer.

3. The terminal-equipped wire according to claim 1 ,
wherein the pair of barrel pieces overlap each other at leading end sides thereof.

4. A terminal-equipped wire configured by crimping a pair of barrel pieces provided on a terminal to an external sheath of a wire, the external sheath being provided on an outer circumferential surface of a core wire,
the pair of barrel pieces are wrapped around the external sheath into a polygonal tube shape that has a plurality of corner portions in a circumferential direction of the external sheath, and
leading end edges of the pair of barrel pieces are arranged on opposite sides of at least one corner portion out of the plurality of corner portions,
wherein mutually matching abutting edge portions of the pair of barrel pieces have an uneven shape on a leading end side in an extension direction of the pair of barrel pieces,
wherein an outer barrel is crimped to the pair of barrel pieces from the outside,
wherein a pair of leading end edges of the outer barrel are arranged on opposite sides of at least one corner portion out of the plurality of the corner portions,
wherein the terminal includes an inner terminal connected to the core wire, a dielectric that houses the inner terminal therein, and an outer terminal that has a housing portion that houses the dielectric,
when divided along an extension direction of the housing portion, the housing portion of the outer terminal includes a first member and a second member, and
wherein the pair of barrel pieces are provided integrated with the first member and the outer barrel is provided integrated with the second member.
