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.

Embodiment Construction

[0028] Next, a rotary electric machine for a vehicle having a wiring member will be described.

[0029] figure 1 shows a plan view representing a stator 1 in a rotating electrical machine for a vehicle according to an embodiment of the present invention, and, figure 2 show figure 1 Partial enlarged top view of part A of the stator shown. For explanatory purposes, figure 2 The stator 1 shown is not filled with the insulating resin material described below. The segmented iron core 2 is composed of layered silicon steel sheets, the resin casing 3 is installed on the layered silicon steel sheets, and, in this embodiment, ten segmented iron cores 2 are arranged on the inner peripheral surface of the stator housing 4 5 to form a single-phase core. In this embodiment, a total of thirty segmented iron cores 2 are used to form a three-phase iron core. An enamelled copper wire is wound around each segmented core 2 to form a coil 6 . A slip ring 7 for supplying power to each coi...

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 ...
