Abstract

An arrangement structure of wiring member for rotating electrical machine is configured in such a manner that a wiring member for rotating electrical machine including a plurality of conductive wires and connecting coil ends of a stator to electrodes of a terminal block in a rotating electrical machine is arranged on an arranging target member. The wiring member for rotating electrical machine includes a holding portion including a molded resin so as to cover all the plurality of conductive wires together and holds the plurality of conductive wires. A cushioning member comprising an elastic body is provided between the holding portion and the arranging target member. The holding portion is arranged on the arranging target member via the cushioning member.

First claim

What is claimed is:

1. An arrangement structure of a wiring member for a rotating electrical machine being configured in such a manner that the wiring member for the rotating electrical machine comprising a plurality of conductive wires and connecting coil ends of a stator to electrodes of a terminal block in the rotating electrical machine is arranged on an arranging target member,
wherein the wiring member for the rotating electrical machine comprises;
a holding portion including a molded resin so as to cover all the plurality of conductive wires together and holds the plurality of conductive wires,
a cushioning member comprising an elastic body is provided between the holding portion and the arranging target member,
wherein the holding portion is arranged on the arranging target member via the cushioning member,
wherein the holding portion further comprises a main body holding the plurality of conductive wires, and plural protruding portions protruding from the main body to cover portions of the plurality of conductive wires extending out of the main body toward the coil ends, and
wherein the cushioning member comprises a main body-protector portion covering a bottom surface of the main body, and protruding portion-protector portions covering bottom surfaces of the plural protruding portions.

2. The arrangement structure of wiring member for the rotating electrical machine according to claim 1 , wherein the cushioning member comprises a softer material than the holding portion.

3. The arrangement structure of wiring member for the rotating electrical machine according to claim 1 , wherein the cushioning member is fixed to at least one of the holding portion and the arranging target member.

4. The arrangement structure of wiring member for the rotating electrical machine according to claim 3 , wherein the cushioning member comprises a sheet-shaped member that is adhered and fixed to at least one of the holding portion and the arranging target member.

5. The arrangement structure of wiring member for the rotating electrical machine according to claim 3 , wherein the cushioning member is molded integrally with the holding portion.

6. The arrangement structure of wiring member for the rotating electrical machine according to claim 1 , wherein the arranging target member comprises a stator core or a housing of the rotating electrical machine.

7. The arrangement structure of wiring member for the rotating electrical machine according to claim 1 ,
wherein the plurality of conductive wires comprise connecting portions to be in contact with and connected to the coil ends respectively, and
wherein each of the connecting portions has a flat surface facing the corresponding coil end.
