Electric wire with terminal and method for manufacturing electric wire with terminal
A method for manufacturing an electric wire with a terminal includes forming a bonded part in which outer peripheral surfaces of strands are bonded to one another on an end portion of a core wire having the strands, in an electric wire in which the end portion is exposed from a covering; installing the bonded part onto a crimp terminal including a bottom part and a pair of caulking pieces extending from the bottom part and facing each other; crimping the caulking pieces to the bonded part, by sandwiching the crimp terminal and the electric wire between a first mold supporting the crimp terminal and a second mold moving relative to the first mold; and cutting a tip end portion projecting to outside from the caulking pieces in the bonded part by a cutting unit, while the caulking pieces are pressing the bonded part toward the bottom part.
1. An electric wire with a terminal, comprising:
an electric wire including a core wire, having a plurality of strands, and a covering that covers the core wire while an end portion of the core wire is exposed; and
a crimp terminal including a core wire crimping part crimped to the core wire, wherein
the crimp terminal includes a linking part that is a wall portion adjacent to a bottom part of the core wire crimping part in an axial direction of the electric wire,
in the core wire, a portion at a tip end side thereof including a portion crimped to the core wire crimping part, is a bonded part in which outer peripheral surfaces of the plurality of strands are bonded to one another,
a tip end surface of the bonded part projects to an outside from the core wire crimping part and is a cut surface,
in the cut surface, end surfaces of the plurality of strands are brought into contact with one another, and face a same direction, and
each of the end surfaces of the plurality of strands is sheared and deformed toward the linking part along a height direction of the crimp terminal.
2. The electric wire with a terminal according to claim 1 , wherein
the end surfaces of the plurality of strands that form the cut surface are sheared and deformed in a same direction.
