Abstract

A rotating electrical machine wiring component is configured to be connected to an armature winding of a rotating electrical machine and includes a conductor wire comprising a conductive metal, and an insulation covering a portion of the conductor wire, wherein the conductor wire comprises a flat plate-shaped connecting portion located at one end and connected to the armature winding, and a bent portion bent by a bending process in a vicinity of the connecting portion, wherein the conductor wire is not covered with the insulation at the connecting portion and the bent portion, and wherein a cross-sectional shape of the conductor wire in a cross-section perpendicular to an extending direction of the conductor wire is rectangular at the connecting portion and circular at the bent portion.

Claims (14)

1 . A rotating electrical machine wiring component configured to be connected to an armature winding of a rotating electrical machine, the rotating electrical machine wiring component comprising:

a conductor wire comprising a conductive metal; and

an insulation covering a portion of the conductor wire,

wherein the conductor wire comprises a flat plate-shaped connecting portion located at one end and connected to the armature winding, and a bent portion bent by a bending process in a vicinity of the connecting portion,

wherein the conductor wire is not covered with the insulation at the connecting portion and the bent portion, and

wherein a cross-sectional shape of the conductor wire in a cross-section perpendicular to an extending direction of the conductor wire is rectangular at the connecting portion and circular at the bent portion.

2 . The rotating electrical machine wiring component, according to claim 1 , wherein the connecting portion is rectangular in shape when viewed from a side where the armature winding to be connected thereto is located, and wherein the conductor wire is bent at the bent portion to turn in a lateral direction of the connecting portion relative to the connecting portion.

3 . The rotating electrical machine wiring component, according to claim 2 , wherein a plurality of ends of the armature winding are connected to the connecting portion, and wherein a distance between the connecting portion and the bent portion is shorter than a length of the connecting portion in a longitudinal direction.

4 . The rotating electrical machine wiring component, according to claim 1 , wherein the insulation covers an outer circumferential surface of the conductor wire at a position farther from the connecting portion than from the bent portion in the extending direction, and wherein a distance between the bent portion and the insulation along the extending direction is shorter than the distance between the connecting portion and the bent portion.

5 . A method for manufacturing a rotating electrical machine wiring component configured to be connected to an armature winding of a rotating electrical machine, the method comprising:

using, as a material, an insulated wire obtained by covering a conductor wire comprising a conductive metal with an insulation;

removing a predetermined length of the insulation at an end of the material;

forming a bent portion by bending the conductor wire of a portion where the insulation has been removed; and

forming a connecting portion to be connected to the armature winding, by processing a portion of the conductor wire on a tip side relative to the bent portion into a flat plate shape.
