Abstract
The invention relates to an injection molding structure of a stator iron core of a rotary transformer. The injection molding structure comprises the stator iron core, an outgoing wire group, a wire-winding insulating frame and a stator coil, wherein the stator iron core, the outgoing wire group and the wire-winding insulating frame are injection-molded into an integrated structure; the outgoing wire group is fixed on the stator iron core in an injection-molding manner and is arranged in an ordering manner; a wire-winding machine can wind the head and the tail of the coil on corresponding terminals of the outgoing wire group, so that not only is the labor saved, but also the error is avoided; and the injection molding layer surrounds the wire-winding position of a tooth-shaped part of the stator iron core or larger area, so that the service life is prolonged.
Description
Technical field
The present invention relates to rotary transformer technology field, refer more particularly to rotary transformer stator core injection structure.
Background technology
Fig. 2 is prior art rotary transformer stator part schematic diagram, including stator core 1, lead-out wire group 2, upper coiling insulating frame 3a, lower coiling insulating frame 3b, groove contract 5.
First manually upper coiling insulating frame 3a, lower bobbin winder bracket insulating frame 3b are loaded stator core 1 upper and lower faces, coiling 4 again, then lead-out wire group 2 is loaded in the groove of stator core 1, artificial insertion groove contract 5 fixes lead-out wire group 2, more troublesome is want artificial to be wrapped on six terminals of lead-out wire group 2 by the corresponding end to end of coil 4, and artificial kinking efficiency is low, fallibility.
Fig. 3 is that prior art rotates set sub-component schematic diagram.
Summary of the invention
In order to overcome the deficiencies in the prior art, the present invention provides a kind of rotary transformer stator core injection structure.
The technical solution used in the present invention is as follows: provide a kind of rotary transformer stator core injection structure. As shown in Figure 1, including stator core 1, lead-out wire group 2, coiling insulating frame 3, stator coil 4, described stator core 1, lead-out wire 2, coiling insulating frame 3, it is injection molded into integrative-structure, lead-out wire group 2 injection moulding is fixed on stator core 1 and arranges in order, winding machines directly on the terminal being wrapped in lead-out wire group 2 correspondence end to end of coil 4, will can both save manually to turn avoid and make mistakes; Injection molded layers encirclement stator core profile of tooth part winding position or more large area, extend the stator life-span.

Fig. 3 is prior art rotary transformer stator module schematic diagram.
Fig. 1 is that the present invention rotates transformation stator module schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, describe the specific embodiment of the present invention in detail:
Fig. 1 is the structural representation of one embodiment of the invention.
A kind of rotary transformer stator core injection structure, including stator core 1, lead-out wire group 2, coiling insulating frame 3, stator coil 4, and described stator core 1 lead-out wire group 2 and coiling insulating frame 3, it is integrated injection structure.
Described stator core 1, is formed by the silicon steel plate stacking with multiple profile of tooth.
Described lead-out wire group 2, is combined by six lines, and one end injection moulding of six lines is fixed on stator core, and ordered arrangement connects with the corresponding end to end of stator coil 4, and the other end is outwards drawn.
Described coiling insulating frame 3, is the injection molded insulating barrier being enclosed in stator core 1 parts of tooth, and as the insulation between stator coil 4 and stator core 1, stator coil 4 is around herein above
Described stator coil 4 includes magnetizing coil, sine coil, cosine coil totally six tail end.By winding machines, stator coil 4 is wound on coiling insulating frame 3, and six of coil 4 corresponding are end to end wrapped on six terminals of described lead-out wire group 2.
The beneficial effect comprise that: improve product quality and production efficiency.
