Portion's sweep colligation is fixed；The top of described toothed projections is provided with and limits the hook-like configuration that described binding strap slides.
Further, described toothed projections surface is provided with groove, and described binding strap embeds in described groove.
Further, described hook-like configuration is shaped as the straight hook of L-shaped.
Further, described hook-like configuration is shaped as arc crotch.
Further, the most uniform auxiliary toothed projections between described toothed projections.
Further, inside described motor casing, two ends are arranged with the first annular groove, are provided with restriction institute in described first annular groove
State the first snap ring of the axial displacement of stator core.
Further, inside described motor casing, two ends are arranged with the second annular groove, are provided with restriction described in described second annular groove
Stator insulation end plate is to the second snap ring of described motor casing end direction displacement.
This utility model has the advantage that with good effect: the uniform toothed projections of stator insulation end plate internal ring, described colligation
Band is previously wound around in described toothed projections, and fixes with described winding wire end bend portions colligation；Described toothed projections
Top be provided with and limit the hook-like configuration that described binding strap slides, prevent in motor rotation vibration to cause described binding strap and institute
State toothed projections to slide and disengage, make stator winding axial, radial direction is all relative with stator core does not moves, it is to avoid calmly
Sub-iron core and the friction of stator winding；And by arranging the first snap ring, limit the axial displacement of described stator core；By setting
Put the second snap ring, make stator core and stator winding line and motor casing become an entirety, it is therefore prevented that relative movement.This reality
With New Energy in the case of not dipping lacquer, the insulation that can meet motor uses requirement.

Detailed description of the invention
For summary of the invention of the present utility model, feature and effect can be further appreciated that, hereby enumerate following example, and coordinate
Accompanying drawing describes in detail as follows:
Referring to Fig. 1～Fig. 3, a kind of submersible electric machine with oil not dipping lacquer stator structure, including motor casing 2, stator core 1
With binding strap 6, it is respectively arranged at two ends with the annular stator insulating end plate 3 of rigidity at described stator core 1；Described stator insulation
End plate 3 is fixed in described motor casing 2, the described stator insulation end plate 3 uniform toothed projections of internal ring 11, described binding strap
6 are previously wound around in described toothed projections 11, and fix with described winding wire 4 end bend portions colligation；Described profile of tooth
The top of protruding 11 is provided with and limits the hook-like configuration that described binding strap slides.
Further, for making described binding strap 6 more securely fix with described toothed projections 11, radially relative is not produced
Sliding, described toothed projections 11 surface also can be provided with groove, and described binding strap 6 embeds in described groove.Can only with institute
The surface portion stating binding strap 6 contact is provided with described groove.
Further, described hook-like configuration shape can be the straight hook of L-shaped.
Further, described hook-like configuration shape can be arc crotch.
Further, for ease of the heat radiation of winding and prevent axis of winding play, in the described profile of tooth of stator insulation end plate 3
Also can uniform auxiliary toothed projections 12 between projection.
Further, inside described motor casing 2, two ends can be arranged with the first annular groove, can be provided with in described first annular groove
