Description

A kind of motor stator insulated skeleton

Technical field

This utility model relates to motor and electromotor skeleton technical field, is specifically related to one Motor stator insulated skeleton.

Background technology

When motor manufacturing, motor stator typically will serve as a contrast when embedding the coil of enamel-covered wire winding Pad dielectric layer and carry out dipping lacquer process, to improve the insulating properties of stator armature.Traditional does Method is the preferable fish paper of liner insulating properties between stator core and enamel wire coil winding, Embed the most again after coil is stoppered by bamboo groove label and carry out paint-dipping drying.In recent years to one Little micromachine generally uses plastic skeleton to carry out isolated insulation.The stator made by this technique, Outward appearance is clean and tidy, good insulation preformance, and make efficiency is high, low cost, general by vast manufacturer All over using.

The insulant of motor and generator unit stator uses the insulant of papery or consolidates at present The insulant of body structure, the insulant of solid structure typically uses injection mold to note Molded, there is compact conformation, insulation distance is reliable, place stable advantage, but this type of The insulation of solid structure is typically made up of 2-3 set injection mold, and die cost is higher；Simultaneously There is the mould of end end, the mould in insulation has groove in groove, has been formed after assembling Electrical machine insulation, manufacture and assembling process in expend more man-hour.

Therefore, for the problems referred to above, the utility model proposes a kind of new technical scheme.

Utility model content

It is good that the purpose of this utility model is to provide a kind of insulation effect, and preparation is simple, reduces Production cost, improves the motor stator insulated skeleton of production efficiency.

This utility model is achieved through the following technical solutions:

A kind of motor stator insulated skeleton, including two frame body, described frame body bag Including end ring, interior ring recess and outer ring recess, described end ring lower end is evenly distributed with ring recess in several With outer ring recess, it is crisscross arranged between outer ring recess and interior ring recess, described end ring, interior ring recess and outer Ring recess is structure as a whole, and by injection mold injection mo(u)lding, has some outside described end ring The insulating gaps that the individual degree of depth is different, is provided with gear line protruding outside insulating gaps.

Further, make-up after upset between two frame body, outer ring recess and interior ring recess it Between connected by buckle-type, overlapped cooperation.

Further, outer ring recess is identical with the quantity of interior ring recess.

Further, described end ring is externally provided with a plurality of transition wire, transition wire and insulating gaps and Gear line projection matches.

The beneficial effects of the utility model are:

1, this structure has only to an injection mold and can complete motor stator insulated skeleton Injection mo(u)lding, reduces the input cost of mould, has saved the production time, improve production Efficiency；

2, by the cooperation that insulating gaps and gear line are protruding, transition wire can be with natural separation to can The insulation distance leaned on, it is not necessary to people position carries out insulation processing again, saves preparation time and material Material.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model；

Fig. 2 is the structural representation of single frame body；

Fig. 3 is transition wire and insulating gaps and the structural representation of gear line male cooperation.

Wherein: frame body, 2, end ring, 3, outer ring recess, 4, interior ring recess, 5, insulation Breach, 6, gear line protruding, 7, transition wire.

Detailed description of the invention

Illustrate below in conjunction with the accompanying drawings this utility model is described further.

As shown in Figures 1 to 3, a kind of motor stator insulated skeleton, including two frame body 1, frame body 1 includes end ring 2, interior ring recess 3 and outer ring recess 4, and end ring 2 lower end is uniform Several in ring recess 3 and outer ring recess 4 is distributed, staggered between outer ring recess 4 and interior ring recess 3 Arranging, end ring 2, interior ring recess 4 and outer ring recess 3 are structure as a whole, and are noted by injection mold Molded, have the different insulating gaps of several degree of depth 5, insulating gaps outside end ring 2 Gear line projection 6 it is provided with outside 5.Make-up after overturning between two frame body 1, outer ring recess 3 It is connected by buckle-type with between interior ring recess 4, overlapped cooperation, outer ring recess 3 and inner ring The quantity of groove 4 is identical, and end ring 2 is externally provided with a plurality of transition wire 7, and transition wire 7 lacks with insulation Mouth 5 and gear line projection 6 match.

Insulation framework of the present utility model is to be made up of two frame body 1, and frame body 1 is led to Crossing injection mold injection mo(u)lding, whole frame body 1 is made up of two parts, the end ring outside groove Insulation in 2 insulation and groove, the end ring 2 outside groove insulate except having general insulation effect, It is provided with the different insulating gaps of the degree of depth 5, these insulating gaps in the outside of end ring 2 simultaneously 5 will be the passage of the interconnective transition wire of motor winding 7, by these insulating gaps 5 The winding that can make different slots is connected, and the degree of depth of insulating gaps 5 is inconsistent simultaneously, has height to have Low, it is to avoid the defective insulation that transition wire 7 contact produces, also set outside insulating gaps 5 Having gear line projection 6, these gear line projections 6 can effectively isolate the transition wire 7 on cylindrical. Insulating Design in groove becomes half to be interior ring recess 4, and half is outer ring recess 3, so by two bones Make-up after frame body 1 upset, the insulation of interior ring recess 4 and the insulation of outer ring recess 3 can be mutual Lap fit, so that all being protected by insulator in motor stator slot.

As it is shown on figure 3, the upper outside gear line projection 6 of end ring 2 insulation by transition wire 7 respectively every Opening, to avoid defective insulation between line, the insulating gaps 5 of different levels can be drawn not simultaneously The transition wire 7 of co-located.

This structure has only to an injection mold can complete the note to motor stator insulated skeleton Molded, reduce the input cost of mould, saved the production time, improve production effect Rate；By the cooperation that insulating gaps and gear line are protruding, transition wire can be with natural separation to reliable Insulation distance, it is not necessary to people position carries out insulation processing again, saves preparation time and material.

The foregoing is only embodiment of the present utility model, not thereby limit this utility model The scope of the claims, every utilize the equivalence knot that this utility model description and accompanying drawing content made Structure or equivalence flow process conversion, or directly or indirectly it is used in other relevant technical fields, all In like manner it is included in scope of patent protection of the present utility model.
