Motor and pump

1 . A motor comprising:

a motor assembly including a rotor rotatable about a central axis and a stator radially opposing the rotor with a gap interposed between the rotor and the stator;

a circuit board located on a first side in an axial direction from the motor assembly; and

a connection terminal electrically connecting the stator and the circuit board; wherein

the stator includes:

a stator core with an annular shape;

an insulating portion attached to the stator core to hold the connection terminal; and

a coil portion including a coil body attached to the stator core with the insulating portion interposed between the stator core and the coil body, and a coil lead wire drawn out from the coil body;

the connection terminal includes:

a board connector connected to the circuit board;

a groove recessed in a direction intersecting the axial direction to allow the coil lead wire to be inserted through the groove along a radial direction; and

a fixture in contact with the insulating portion in the axial direction, the coil lead wire being press-fitted into the groove;

the insulating portion includes a wall portion opposing the groove in the radial direction and extending in the axial direction; and

the wall portion includes a lead wire contact portion that is located on the first side in the axial direction from a surface of the groove opposing the first side in the axial direction and in contact with the coil lead wire in the axial direction.

2 . The motor according to claim 1 , wherein

the wall portion includes a recess that is recessed from an end portion of the wall portion, the end portion extending from the first side in the axial direction toward a second side in the axial direction and that is open along the radial direction;

the coil lead wire is inserted into the recess; and

the lead wire contact portion is a surface among inner surfaces of the recess, the surface opposing the first side in the axial direction.

3 . The motor according to claim 1 , wherein

the connection terminal includes a terminal body extending in the axial direction, and an arm portion protruding from the terminal body in a direction intersecting the axial direction and including the groove; and

the groove includes a first groove and a second groove that are aligned in the radial direction and through which one coil lead wire is inserted.

4 . The motor according to claim 3 , wherein

the connection terminal includes two of the arm portions;

a first of the two of the arm portions protrudes from the terminal body toward a first side in a circumferential direction; and

a second of the two of the arm portions protrudes from the terminal body toward a second side in the circumferential direction.

5 . The motor according to claim 3 , wherein

the fixture includes a fixing surface opposing the first side in the axial direction; and

the insulating portion includes a support surface opposing the second side in the axial direction and supporting the fixing surface in the axial direction.

6 . The motor according to claim 5 , wherein

the connection terminal includes a leg portion extending from the terminal body toward the second side in the axial direction and including the fixture;

the insulating portion includes a hole recessed from an end portion of the insulating portion, the end portion extending from the first side in the axial direction toward the second side in the axial direction; and

the leg portion is located inside the hole.

7 . The motor according to claim 6 , wherein

the leg portion includes a leg hole passing through the leg portion in the radial direction; and

the fixture extends from a surface among inner surfaces of the leg hole, the surface opposing the first side in the axial direction, toward a direction opposing a space between the first side in the axial direction and the first side in the radial direction, and is elastically deformable in the radial direction.

8 . A pump apparatus comprising:

the motor according to claim 1 ; and

a pump connected to the rotor.
