Abstract
A stator according to an embodiment includes a stator core that includes a plurality of teeth that extend from a ring-shaped body part in one radial direction thereof, an insulator that covers the plurality of teeth from both sides in an axial direction of the stator core, a coil that is wound around each of the plurality of teeth via the insulator, a terminal block part that extends from the insulator in a radial direction opposite to the one radial direction, includes a plurality of terminals with a terminal end of a winding wire that composes the coil being bound to one end thereof, and is formed integrally with the insulator, and a connector housing that includes a connection part for the terminal block part, stores another end of each of the plurality of terminals, and is connected to an external connector.

A stator, comprising:
- a stator core that includes a plurality of teeth that extend from a ring-shaped body part in one radial direction thereof;
- an insulator that covers the plurality of teeth from both sides in an axial direction of the stator core;
- a coil that is wound around each of the plurality of teeth via the insulator;
- a terminal block part that extends from the insulator in a radial direction opposite to the one radial direction, includes a plurality of terminals with a terminal end of a winding wire that composes the coil being bound to one end thereof, and is formed integrally with the insulator;
- a connector housing that includes a connection part for the terminal block part, stores another end of each of the plurality of terminals, and is connected to an external connector;
- and
- a terminal cover that covers the plurality of terminals from a side of the one end of the plurality of terminals, wherein
- a first through-hole that overlaps with a through-hole of the stator core is formed in the terminal block part;
- a third through-hole that overlaps with the first through-hole is formed in the terminal cover;
- the connector housing includes, as the connection part, a first protrusion part that is formed to penetrate through the through-hole of the stator core, the first through-hole, and the third through-hole;
- and
- a tip of the first protrusion part that penetrates through the through-hole of the stator core, the first through-hole, and the third through-hole is fixed on the terminal cover and thereby connected to the terminal block part.
