Abstract

A guide member includes a first diametrically directed side guide section and a second diametrically directed side guide section formed by bending a single member at a bent portion. The first diametrically directed side guide section guides predetermined portions of electric conductors on a diametrically directed side of a slot. Further, the second diametrically directed side guide section guides predetermined portions of the electric conductors on a diametrically directed side of another slot adjacent to the slot. The bent portion is supported by a supporting body.

First claim

What is claimed is:

1. An electric conductor insertion device configured to insert predetermined portions of electric conductors with respect to slots which are formed in plurality in a stator core, together with being formed in linear shapes including diametrically directed sides extending along diametrical directions of the stator core, and circumferential sides extending along a circumferential direction of the stator core, and in which insulating papers are respectively arranged, the electric conductor insertion device comprising:
a guide member configured to guide the predetermined portions of the electric conductors into the slots; and
a supporting body configured to support the guide member;
wherein, by a single member being bent at a bent portion, the guide member includes a first diametrically directed side guide section adapted to guide the predetermined portions of the electric conductors on a diametrically directed side of a first slot, and a second diametrically directed side guide section adapted to guide the predetermined portions of the electric conductors on a diametrically directed side of a second slot adjacent to the first slot, together with the first diametrically directed side guide section and the second diametrically directed side guide section forming an inverted V-shape with the bent portion forming an apex thereof, and the bent portion is supported by the supporting body,
wherein the first diametrically directed side guide section, at a time of approaching toward the first slot, presses the insulating paper inside the first slot toward an inner wall side of the diametrically directed sides of the first slot, and the second diametrically directed side guide section, at a time of approaching toward the second slot, presses the insulating paper inside the second slot toward an inner wall side of the diametrically directed sides of the second slot;
further comprising a second supporting body, wherein the second supporting body includes an inner circumferentially directed side guide section adapted to guide the predetermined portions of the electric conductors on a circumferentially directed side of an inner circumference of the second slot.

2. The insertion device according to claim 1 , wherein the guide member further includes an outer circumferentially directed side guide section adapted to guide the predetermined portions of the electric conductors on a circumferentially directed side of an outer circumferential side of the second slot.

3. The insertion device according to claim 1 , wherein a first engagement part is provided on the second supporting body, and a second engagement part that engages with the first engagement part is provided on the supporting body, and further comprising a supporting body displacement mechanism adapted to cause the second supporting body and the supporting body, which are connected together mutually by engagement of the first engagement part and the second engagement part, to be displaced together integrally.

4. The insertion device according to claim 1 , wherein the supporting body is formed in an inverted V-shape, and includes a bent portion mounting member on which the bent portion of the guide member is mounted.

5. The insertion device according to claim 4 , further comprising a member including a bent portion sandwiching part adapted to sandwich, together with the bent portion mounting member, the bent portion that is mounted on the bent portion mounting member.

6. The insertion device according to claim 2 , wherein an outer circumferentially directed side guide section mounting member on which the outer circumferentially directed side guide section is mounted is provided on the supporting body, and further comprising a member including an outer circumferentially directed side guide section sandwiching part adapted to sandwich, together with the outer circumferentially directed side guide section mounting member, the outer circumferentially directed side guide section that is mounted on the outer circumferentially directed side guide section mounting member.

7. The insertion device according to claim 4 , wherein an outer circumferentially directed side guide section mounting member on which the outer circumferentially directed side guide section is mounted is provided on the supporting body, and further wherein:
there are provided integrally on a single member:
an outer circumferentially directed side guide section sandwiching part adapted to sandwich, together with the outer circumferentially directed side guide section mounting member, the outer circumferentially directed side guide section that is mounted on the outer circumferentially directed side guide section mounting member; and
a bent portion sandwiching part adapted to sandwich, together with the bent portion mounting member, the bent portion that is mounted on the bent portion mounting member.
