Abstract

A coil wire module for a rotating electric machine, the core wire module including: a plurality of coil wires that are configured to be provided in a core of the rotating electric machine; and a clip having a pair of elastic pieces, wherein: the plurality of coil wires each have a connection end that is configured to be exposed from an end of the core, the clip is elastically deformable in a manner that changes a width of the pair of elastic pieces, and in a state where the pair of elastic pieces pinch together at least two of the connection ends of the plurality of coil wires, the at least two of the connection ends are kept in contact with each other by an elastic force of the clip.

First claim

The invention claimed is:

1 . A coil wire module for a rotating electric machine, the coil wire module comprising:
a plurality of coil wires that are configured to be provided in a core of the rotating electric machine; a first clip having a pair of first elastic pieces; and a second clip having a pair of second elastic pieces, wherein:
each coil wire among the plurality of coil wires has a connection end that is configured to be exposed from an end of the core,
the first clip is elastically deformable in a manner that changes a distance between the first elastic pieces and the second clip is elastically deformable in a manner that changes a distance between the second elastic pieces,
in a state where the pair of first elastic pieces pinch together at least two first connection ends among the connection ends of the plurality of coil wires, the at least two first connection ends are kept in contact with each other by an elastic force of the first clip, and in a state where the pair of second elastic pieces pinch together at least two second connection ends among the connection ends of the plurality of coil wires, the at least two second connection ends are kept in contact with each other by an elastic force of the second clip,
the second clip is located on an inner peripheral side of the coil wire module with respect to the first clip, and
the first clip and the second clip are located at different positions in a circumferential direction of the core.

2 . The coil wire module according to claim 1 , further comprising:
a third clip located on an inner peripheral side with respect to the second clip, wherein the third clip is located at a same position to the first clip in the circumferential direction of the core and at a different position to the second clip in the circumferential direction of the core.

3 . The coil wire module according to claim 1 ,
wherein the first elastic pieces pinch together a plurality of sets of the at least two first connection ends.

4 . The coil wire module according to claim 3 , further comprising:
an insulation that insulates the plurality of sets of the at least two first connection ends from each other.

5 . The coil wire module according to claim 1 , wherein:
the first connection ends and the second connection ends each extend in a direction not parallel to a rotation axis of the rotating electric machine, and the first elastic pieces pinch together end portions of the first connection ends, the end portions of the first connection ends extending in same directions as the first connection ends, and the second elastic pieces pinch together end portions of the second connection ends, the end portions of the second connection ends extending in same directions as the second connection ends.

6 . The coil wire module according to claim 1 ,
further comprising a coupler that couples the first clip and the second clip together, such that the first clip and the second clip are lined up at an interval from each other in a circumferential direction of the core.

7 . The coil wire module according to claim 6 ,
wherein all parts of the coupler have a uniform thickness.

8 . A coil wire module for a rotating electric machine, the coil wire module comprising:
a plurality of coil wires that are configured to be provided in a core of the rotating electric machine; a first clip having a pair of first elastic pieces; a second clip having a pair of second elastic pieces; and a coupler that couples the first clip and the second clip together, such that the first clip and the second clip are lined up at an interval from each other in a circumferential direction of the core, wherein:
each coil wire among the plurality of coil wires has a connection end that is configured to be exposed from an end of the core,
the first clip is elastically deformable in a manner that changes a distance between the first elastic pieces and the second clip is elastically deformable in a manner that changes a distance between the second elastic pieces, and
in a state where the pair of first elastic pieces pinch together at least two first connection ends among the connection ends of the plurality of coil wires, the at least two first connection ends are kept in contact with each other by an elastic force of the first clip, and in a state where the pair of second elastic pieces pinch together at least two second connection ends among the connection ends of the plurality of coil wires, the at least two second connection ends are kept in contact with each other by an elastic force of the second clip.

9 . The coil wire module according to claim 8 ,
wherein all parts of the coupler have a uniform thickness.
