Wiring parts for automotive rotating electrical machines

Abstract

The invention discloses a wiring part of a rotating electrical machine for a vehicle, comprising segmental metals (27, 28, 29) made of conductive wires and arranged in the circumferential direction (26) of the rotating electrical machine, wherein the segmental metals (27 , 28, 29) include: a main body (41), which has a first straight portion (411); a second straight portion (451), which passes through each end of the main body (41) in the radial direction of the rotating electrical machine ( 21) is formed by bending so as to have an obtuse angle (44) between the first straight portion (411) and the second straight portion (451); and, the upright portion (31) at the second straight portion (451) It is formed by bending in the rotation axis direction (25) of the electric rotating machine, and wherein the upstanding portions (31) of the segment metals (27, 28, 29) adjacent to each other are made electrically conductive to each other.

Description

technical field [0001] The present invention relates to a wiring part of a rotary electric machine for a vehicle used in a power train of an electric vehicle, a hybrid vehicle, or the like. Background technique [0002] A rotary electric machine for a vehicle generally includes a stator composed of a plurality of segmented iron cores arranged in the circumferential direction of the stator in order to increase the coil occupancy rate in the stator. Each segmented core is prepared by winding copper wire around it. Each end of the segmented core is connected to a wiring member, and power is supplied to the segmented core via the wiring member. [0003] A well-known wiring component is disclosed in JP2010-110144A, including a plurality of segment wires (wire segments, segment wires), the segment wires are made of conductive wires, and are arranged in the circumferential direction to form a ring shape, And, each of the segment wires includes: protrusions forming protrusions at ...

AI Technical Summary

Problems solved by technology

[0004] However, according to the known rotating electric machine, since bending processing is applied to the protruding portion and the upright portion, it is necessary to provide a space corresponding to the respective bending portions of the protruding portion and the upright portion, thereby increasing the radial distance of the protruding portion. Protrusion amount, and increase the outer diameter of the wiring part

In addition, since each end portion of the segment wire is formed into a three-dimensional shape by applying bending work to the protruding portion and the upright portion, the bending workability is lowered.
