Insulator, stator, and rotating electrical machine using these

A stator, comprising:

• a plurality of winding wire blocks that are disposed in an annular shape;
• a plurality of split cores that compose a part of the plurality of winding wire blocks and are combined with each other to compose a stator core with an annular shape;
• an insulator that composes a part of the plurality of winding wire blocks and is attached to each of the plurality of split cores;
• a coil conductor wire that composes a part of the plurality of winding wire blocks and has a wound portion wound around each of the plurality of split cores via the insulator and a bridging portion drawn out from the wound portion;
• and
• a regulating member that regulates movement of the coil conductor wire, wherein
• the insulator has an accommodating portion that accommodates the bridging portion,
• the accommodating portion includes
• a first surface and a second surface that form mutually facing surfaces, and
• opening portions that communicate with each other and are formed in each of the first surface and the second surface,
• the regulating member is configured of a bendable member and is configured to be fixable to the accommodating portion in a state of an annular shape wound around the bridging portion with the regulating member inserted through the opening portion formed in the first surface and the opening portion formed in the second surface,
• the accommodating portion has, at an end portion of at least one of the first surface and the second surface, a recessed portion that receives the regulating member,
• the opening portion formed in the first surface is a through-hole that is formed to penetrate through the first surface in a thickness direction, and
• the recessed portion is provided in a region obtained by extending the opening portion in the first surface in an axial direction of the stator core.
