Abstract

A motor connecting member, which connects a motor winding and a terminal block, includes a terminal to be connected to the terminal block, a winding connecting portion to be connected to the motor winding, and an extended portion extending between the terminal and the winding connecting portion. The extended portion is made by plastically deforming a single wire having a circular cross section, and is bent in a predetermined shape fitted for connection between an end of the motor winding connected with the winding connecting portion and the terminal block.

First claim

What is claimed is:

1. A motor connecting member, which connects a motor winding and a terminal block, comprising:
a terminal to be connected to the terminal block;
a winding connecting portion to be connected to the motor winding; and
an extended portion extending between the terminal and the winding connecting portion,
wherein the extended portion is made by plastically deforming a single wire having a circular cross section, and is bent in a predetermined shape fitted for connection between an end of the motor winding connected with the winding connecting portion and the terminal block,
wherein the winding connecting portion is formed integrally with and extended along the extended portion by and plastically deforming the single wire, and a connecting surface, which is directly connected to the motor winding, is formed as a flat surface,
wherein the winding connecting portion comprises a plate shape, and a thickness smaller than a diameter of the extended portion.

2. The motor connecting member according to claim 1 , wherein the winding connecting portion includes a plurality of contacts spaced apart from each other in a longitudinal direction thereof, to be connected with the motor winding.

3. The motor connecting member according to claim 1 , further comprising a weld joint that electrically connects the flat connecting surface of the winding connecting portion to the motor winding.

4. The motor connecting member according to claim 1 , wherein the extended portion is coated by an insulating member made of a resin.

5. The motor connecting member according to claim 1 , wherein the terminal, the winding connecting portion, and the extended portion are not coated by an insulating member.

6. A motor device, comprising: the motor connecting member according to claim 1 , and a motor in which the motor winding is connected to the winding connecting portion.

7. The motor connecting member according to claim 1 , wherein the winding connecting portion includes only a single flat connecting surface that is directly connected to the motor winding.
