Abstract

According to the method for connecting motor wire of the present invention, wire as a first wire having folding part is connected to lead as a first lead or a second wire, each having connecting part, with connection terminal having crimping part. After folding part is folded one or more times, folding part and connecting part are crimped at crimping part.

Claims

1. A method for connecting motor wires in which a first wire having an end suitable for folding is connected to a conductive member having a connecting part, the method comprising:

folding the end of the first wire at least once;

inserting the end of the first wire and the connecting part of the conductive member into a connection terminal having a crimping part; and

crimping the crimping part so that the folded end of the first wire and the connecting part of the conductive member substantially fit in a space defined by the crimping part,

wherein the conductive member has a diameter greater than a diameter of the first wire, and when crimped, the first wire and the conductive member have a predetermined amount of distortion so that the first wire and the conductive member are electrically and mechanically connected, and

wherein crimping the crimping part is carried out by a crimping machine configured to crimp motor wires having different diameters with connection terminals having a single size.

2. The method for connecting motor wires according to claim 1, wherein the conductive member is a lead.

3. The method for connecting motor wires according to claim 1, wherein the conductive member is a wire.

4. The method for connecting motor wires according to claim 1, wherein the first wire includes at least one of a copper wire, an aluminum wire, and a copper-clad aluminum wire.

5. The method for connecting motor wires according to claim 1, wherein each of the first wire and the conductive member is a single wire.

6. The method for connecting motor wires according to claim 1, wherein the conductive member is a twisted wire.

7. The method for connecting motor wires according to claim 1, wherein the end of the first wire is folded at least twice.
