Abstract

A motor includes a stator core having an annular shape, a coil wound around a tooth of the stator core, a first terminal electrically connected to the coil, a housing that houses the first terminal, and a second terminal at least partially inserted into the first terminal housed in the housing. The second terminal includes an electrical connecting portion inserted into the first terminal and electrically connected to the first terminal. The housing includes a first restricting portion that restricts movement, in a circumferential direction of the stator core, of a portion of the second terminal other than the electrical connecting portion.

First claim

The invention claimed is:

1. A motor comprising:
a stator core having an annular shape;
a coil wound around a tooth of the stator core;
a first terminal electrically connected to the coil;
a housing that houses the first terminal; and
a second terminal at least partially inserted into the first terminal housed in the housing,
the second terminal including an electrical connecting portion inserted into the first terminal and electrically connected to the first terminal, and
the housing including a first restricting portion that is adjacent to a portion of the second terminal that is not inserted into the first terminal and the first restricting portion restricts movement, in a circumferential direction of the stator core, of the portion of the second terminal.

2. The motor according to claim 1 , wherein
the housing includes a housing body that houses the first terminal, and
the first restricting portion is a protrusion protruding from the housing body.

3. The motor according to claim 1 , wherein
the housing includes a second restricting portion that restricts movement, toward at least one side in an axial direction of the stator core, of the portion of the second terminal other than the electrical connecting portion.

4. The motor according to claim 1 , wherein
the second terminal is bent at a bent portion,
the second terminal includes a wire connecting portion provided on an opposite side of the bent portion from the electrical connecting portion, and
the first restricting portion is provided closer to the wire connecting portion than to the bent portion in the housing.

5. The motor according to claim 1 , further comprising:
an insulator attached to the stator core,
the housing being provided integrally with the insulator.

6. A compressor including the motor according to claim 1 , the compressor further comprising:
a compression mechanism configured to be driven by the motor.

7. A fan motor including the motor according to claim 1 , the fan motor further comprising:
a fan configured to be driven by the motor.
