Abstract
The utility model relate to motor field and especially to a stator core insulating structure. The stator core insulating structure comprises an injection molding sleeve sleeved on the outer layer of an iron core winding skeleton. The outward end portion of the iron core winding skeleton is arranged outside the injection molding sleeve. The entire periphery of the iron core winding skeleton is wrapped in the injection molding sleeve which is used for substituting for a coating layer in the prior art. The injection molding sleeve is durable and uneasy to miss and damage so as to achieve reliable performance of the iron core. The injection molding sleeve comprises a wiring seat covering three holes on a stator core circular ring. A part, corresponding to the three holes on the stator core circular ring, of the wiring seat is hollowed out. Wiring soldering lugs in one-to-one correspondence with the three holes are fixed on the wiring seat. Therefore, when a stator is assembled, leading-out wires are not required to be bound and wire cores are soldered on the wiring soldering lugs. Thus, easy manipulation and a reliable wire leading manner are achieved. By means of the technical scheme, the insulating effect of the stator is guaranteed and the insulating layer is uneasy to damage. The stator core insulating structure is easy to use and can be reworked for secondary use. The product process flow is simplified so as to be easy for workers to manipulate.
Description
Technical field
The utility model relates to machine field, refers to especially a kind of stator core insulation structure.
Background technology
Existing stator core insulation layer adopts coating processes conventionally, and this Insulation Scheme is often with these problems: 1), because stator core is thicker, external diameter is large, causes coat became uneven, easy to crack coming off; 2) technique of coating stator is more complicated, and after applying, stator outer diameter need be processed guarantee stator concentricity; 3) while applying, coating insulating powder used belongs to powdery type containing noxious substance, infringement staff health, not environmental protection; 4) product is unfavorable for secondary coiling, and insulating barrier damage is serious.
Utility model content
The utility model proposes a kind of stator core insulation structure, it can promote the class of insulation of iron core and the reliability of insulating barrier, reduces the complexity of process procedure.
The technical solution of the utility model is achieved in that a kind of stator core insulation structure, comprises and is enclosed within the outer field injection moulding cover of iron core winding skeleton, and the deployment outward of described iron core winding skeleton is outside described injection moulding cover.Iron core winding skeleton complete cycle is injection molding cover parcel, substitutes coat of the prior art with this injection moulding cover, and it is durable is difficult for damagedly, makes iron core dependable performance, and the complexity of minimizing process procedure, has promoted production efficiency.
Preferably, described injection moulding cover is interior axis placing hole, the outer edge of this injection moulding cover axis hole edge covering stator iron core annulus, and described injection moulding cover axis hole edge extends internally and is provided with Pulling-off prevention clamp.This structure of injection moulding cover has been avoided the installing hole on stator core annulus, and covers for heat radiation reduces unnecessary parcel.Because injection moulding cover is different from coat, and the impact that expanded with heat and contract with cold by temperature, for avoiding slippage to go out, therefore Pulling-off prevention clamp is set.
Consideration for injection moulding cover to stator core volume and fastness own, aborning, preferably, the wall thickness that described injection moulding is placed on the outer place of injection moulding cover is 1mm, injection moulding cover axis hole edge extends axially and is the tubulose that is highly not less than 5mm.
During stator assembling, from the lead-out wire in three-phase hole, need colligation, and lead-in wire is inconvenient, therefore, the injection moulding cover of the technical program comprises the junction block in three-phase hole on covering stator iron core annulus, on the corresponding stator core annulus of this junction block, the part hollow out in three-phase hole, is fixed with and described three-phase hole wiring weld tabs one to one at junction block.When assembling, lead-out wire is without colligation like this, and core is welded on wiring weld tabs, makes operation simpler, and lead-out wire mode is more reliable.Wiring weld tabs can be to embed wherein in junction block moulding.The height that the tubulose of one end of wiring weld tabs protrudes can injection moulding cover be set and be set to 6.5mm, the height that the tubulose of the injection moulding cover other end protrudes is set to 5mm.
By the technical program, the insulation effect of stator is guaranteed, and insulating barrier is durable not fragile, easy to use, and the product secondary of can doing over again is used, and product process flow is simplified, and is easy to employee operation.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the Facad structure schematic diagram of an embodiment of the utility model stator core insulation structure;
Fig. 2 is the generalized section of stator core insulation structure shown in Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of stator core insulation structure, comprises and is enclosed within the outer field injection moulding cover 2 of iron core winding skeleton 11, the deployment outward of described iron core winding skeleton 11 is outside described injection moulding cover 2.In conjunction with Fig. 1, Fig. 2, can see, iron core winding skeleton 11 complete cycles are injection molding cover 2 parcels, substitute coat of the prior art with this injection moulding cover 2, and it is durable is difficult for damagedly, makes iron core dependable performance, and the complexity of minimizing process procedure, has promoted production efficiency.
As depicted in figs. 1 and 2, described injection moulding cover 2 is interior axis placing hole to preferred structure, and the outer edge of 2 axis hole edge covering stator iron core annulus 12 is overlapped in this injection moulding, and described injection moulding is overlapped 2 axis hole edges and extended internally and be provided with Pulling-off prevention clamp 21.This structure of injection moulding cover 2 has been avoided the installing hole on stator core annulus 12, and covers for heat radiation reduces unnecessary parcel.Because injection moulding cover 2 is different from coat, and the impact that expanded with heat and contract with cold by temperature, for avoiding slippage to go out, therefore Pulling-off prevention clamp 21 is set.
For the consideration of 2 pairs of stator core volumes of injection moulding cover and fastness own, aborning, preferably, the wall thickness that described injection moulding cover 2 is placed in injection moulding cover 2 outer places are 1mm, and injection moulding is overlapped 2 axis hole edges and extended axially and be the tubulose that is highly not less than 5mm.
