ELECTRIC WIRE CONNECTION STRUCTURE AND ELECTRIC WIRE CONNECTION METHOD

摘要

A structure of an electric wire for connection includes a conductor end portion of the electric wire comprised of a plurality of core wires. The conductor end portion is compressed by press-forming that pressurizes from the side of an outer peripheral surface thereof toward the side of the axis thereof. The conductor end portion is formed with a press-formed surface by the press-forming on an outer peripheral surface thereof, the press-formed surface being a surface that extends in an axial direction of the conductor end portion and being in the shape of steps that come close to the axis of the conductor end portion from a root side of the conductor end portion toward a tip side of the conductor end portion.

1. A structure of an electric wire for connection, the electric wire comprising:
a conductor end portion that is an end portion of the electric wire comprised of a plurality of core wires, wherein the conductor end portion is to be compressed by press-forming that pressurizes from the side of an outer peripheral surface of the conductor end portion toward the side of an axis of the conductor end portion, and to be electrically connected with a connected portion by ultra joining, wherein the conductor end portion is formed with a press-formed surface by the press-forming on an outer peripheral surface thereof, the press-formed surface being a surface that extends in an axial direction of the conductor end portion and being in the shape of steps that come close to the axis of the conductor end portion from a root side of the conductor end portion toward a tip side of the conductor end portion.
