Abstract

Provided is a feeding body, for a rotary electric machine, capable of preventing short between a feeding body and a stator or the like caused by vibration or the like. A feeding body, for a rotary electric machine such as a motor and generator, includes: a power supply main body including a conductor such as copper; a terminal portion formed at one end of the power supply main body; and a protection portion made from a resin material molded to a connection part connected with the terminal portion on the power supply main body, wherein the protection portion includes a protrusion protruding toward a stator of the rotary electric machine.

First claim

The invention claimed is:

1. A feeding unit for a rotary electric machine, comprising:
a plurality of feeding bodies, each of the plurality of feeding bodies corresponding to a different phase and comprising a power supply main body including a conductor,
wherein a terminal portion is formed at one end of the power supply main body of one of the plurality of feeding bodies,
a protection portion is molded on a connection part of the terminal portion of the power supply main body, and
the protection portion includes a plurality of protrusions protruding toward a stator, one protrusion of the plurality of protrusions having a first width different from a second width of another protrusion of the plurality of protrusions, the one protrusion being sandwiched between the stator and the power supply main body of another of the plurality of feeding bodies.

2. The feeding body for a rotary electric machine according to claim 1 ,
wherein the plurality of protrusions are:
made of same resin material as the protection portion; and
formed integrally with the protection portion when the protection portion is formed.

3. The feeding body for a rotary electric machine according to claim 1 ,
wherein the protection portion includes:
a clip fitted to the power supply main body; and
a cover portion covering the clip which is formed by molding into a state that a clamp portion of the clip is sandwiched by a mold, and the power supply main body is disposed in a cavity of the mold, and
wherein the clip and the cover portion are made of a same resin material.

4. The feeding body for a rotary electric machine according to claim 1 ,
wherein at least one of the plurality of protrusions is substantially in a prism shape, and wherein an edge portion and a marginal portion thereof are chamfered or rounded.

5. The feeding body for a rotary electric machine according to claim 1 ,
wherein the each of the plurality of protrusions is provided with a pair of grip surfaces facing each other back to back.
