Abstract

A wiring member for rotating electrical machine that connects coil ends of a stator to electrodes of a terminal block in a rotating electrical machine. The wiring member includes a plurality of conductive wires, and a holding portion for holding the plurality of conductive wires. The holding portion includes an adhesion portion adhered and fixed to a fixing target member. A fixing structure of wiring member for rotating electrical machine is configured that the wiring member for rotating electrical machine including the plurality of conductive wires and connecting coil ends of a stator to electrodes of a terminal block in the rotating electrical machine is fixed to a fixing target member. The rotating electrical machine includes the stator including a stator core and a plurality of coil pieces adhered and fixed to the stator core, and the wiring member for rotating electrical machine.

First claim

What is claimed is:

1. A wiring member for a rotating electrical machine that connects coil ends of a stator to electrodes of a terminal block in a rotating electrical machine including a rotor, the wiring member comprising:
a plurality of conductive wires; and
a holding portion for holding the plurality of conductive wires, wherein the holding portion comprises an adhesion portion adhered and fixed to a fixing target member,
wherein the adhesion portion comprises an introduction hole for introducing an adhesive to an interface between the holding portion and the fixing target member, and
wherein the introduction hole penetrates through a portion of the adhesion portion in a facing direction where the adhesion portion and the fixing target member are facing each other in a rotational axis direction of the rotor.

2. The wiring member for rotating electrical machine according to claim 1 , wherein the adhesion portion comprises an adhesive filling portion formed in a recessed shape on the bottom surface of the holding portion, and the introduction hole is configured to allow the adhesive to be introduced into the adhesive filling portion.

3. The wiring member for rotating electrical machine according to claim 1 , wherein the holding portion comprises a plurality of holders holding the conductive wires in shape of wiring, and a molded resin portion including a molded resin so as to partially cover the plurality of holders and integrating the plurality of holders, and the adhesion portion is provided on the holder.

4. The wiring member for rotating electrical machine according to claim 3 , wherein the holding portion comprises the molded resin portion provided to cover all the plurality of conductive wires together, and the adhesion portion is provided on a side where the plurality of conductive wires extend out to be connected to the coil ends, relative to the molded resin portion.

5. A rotating electrical machine, comprising:
a stator comprising a stator core and a plurality of coil pieces adhered and fixed to the stator core;
a rotor, and
the wiring member for rotating electrical machine according to claim 1 ,
wherein the fixing target member comprises the stator core, and an adhesive for adhering and fixing the plurality of coil pieces to the stator core comprises the same material as the adhesive for adhering and fixing the holding portion to the stator core.

6. A fixing structure of wiring member for rotating electrical machine, the fixing structure being configured that a wiring member for rotating electrical machine comprising a plurality of conductive wires and connecting coil ends of a stator to electrodes of a terminal block in a rotating electrical machine including a rotor is fixed to a fixing target member,
wherein the wiring member for rotating electrical machine comprises a holding portion for holding the plurality of conductive wires, and the holding portion includes an adhesion portion that is adhered and fixed to the fixing target member,
wherein the adhesion portion comprises an introduction hole for introducing an adhesive to an interface between the holding portion and the fixing target member, and
wherein the introduction hole penetrates through a portion of the adhesion portion in a facing direction where the adhesion portion and the fixing target member are facing each other in a rotational axis direction of the rotor.

7. The fixing structure of wiring member for rotating electrical machine according to claim 6 , wherein an adhesive filling portion having a recessed shape and to be filled with an adhesive is provided on one or both of the bottom surface of the holding portion and the fixing target member, and the holding portion is adhered and fixed to the fixing target member by the adhesive filling the adhesive filling portion.

8. The fixing structure of wiring member for rotating electrical machine according to claim 7 , wherein the holding portion comprises an introduction hole formed to open on a side opposite to the bottom surface and provided to introduce the adhesive into the adhesive filling portion.

9. The fixing structure of wiring member for rotating electrical machine according to claim 7 , wherein the adhesive comprises a thermosetting resin.
