Usually the method for packing that adopts has at present: 1, epoxy encapsulation method.2, Plastic Package method.
In existing method for packing, Plastic Package is the most bothersome, needs to make mould and needs injection molding machine equipment.Coil is inserted in the mould, inject by the plastics of injection molding machine with fusing, the cooling back is with regard to encapsulated moulding.The cost of this method for packing is than higher, and last size is bigger.Because plastics have certain fragility, if encapsulated layer is too thin, be easy in production and use, fracture phenomena take place, finally cause seal failure.
Though the epoxy encapsulation method can be saved mould, it solidifies, and back hardness is big, adhesion is an one pack system greatly and not.Therefore more loaded down with trivial details when production operation, need each component raw material of mediation, if when coating epoxy resin, do not wishing that coating part has been stained with epoxy resin accidentally, after curing, be difficult to remove.As Chinese patent 200320102466.X " inductance coil can ", two shells about the coil outside makes, two shells fasten the back at the inner filling epoxy resin of shell.
The disclosed solenoid of Chinese patent 00251767.1 " tractive electromagnet " adopts sealed cast to improve the water resistance of solenoid.This patent is not elaborated to the material of solenoid sealed cast.
Chinese patent 96123315.X " transformer coiling and manufacture method thereof " relates to the inside and outside surface of adopting preimpregnating insulation sheet 118 to come winding around, insulating trip 118 is with epoxy resin impregnated glass fabric, comes the axle head of encapsulated coil then with the heat curing-type silicone rubber.But this invention is to come at the resin molded coil of transformer, is not suitable for the solenoid that adopts enamelled wire and skeleton structure.
Therefore, in current material, find a kind of energy to adapt to various operational environments, especially the solenoid encapsulated layer material that under various adverse circumstances, has excellent toughness, insulating properties, oil resistance and corrosion resistance, and find out corresponding method for packing to reduce production costs, be that one of ordinary skill in the art expect the problem that solves.
Summary of the invention
Described problem at present solenoid method for packing existence, the object of the present invention is to provide a kind of energy to adapt to various operational environments, especially the solenoid encapsulated layer material and the method that have excellent toughness, insulating properties, oil resistance and corrosion resistance under various adverse circumstances, silicone adhesive promptly of the present invention is at solenoid Application in Packaging and method for packing.
The object of the present invention is achieved like this: silicone adhesive is characterized in that in the solenoid Application in Packaging: twine enamelled wire coiling and encapsulation silicone adhesive sealable outer composition solenoid on the I shape coil rack.
A kind of method for packing of solenoid is characterized in that: described electromagnetic coil skeleton places on the rotating shaft and is rotated, and the enamelled wire coiling outer surface coating silicone adhesive that is wound on the coil rack is formed the potting layer.
The thickness of described potting layer is between 0.3mm-5mm.
Compared to existing technology, the present invention has following advantage:
1, adopts the inventive method, make the encapsulated layer of solenoid have good toughness, insulating properties, oil resistance and corrosion resistance;
2, can guarantee that the size of solenoid is littler;
3, simple, the enforcement easily of the inventive method, and cost is lower.
The invention will be further described below in conjunction with the drawings and specific embodiments.
Description of drawings

Embodiment
As shown in Figure 1, silicone adhesive of the present invention is to twine enamelled wire coiling 2 and encapsulation silicone adhesive sealable outer 1 composition solenoid on I shape coil rack 3 in the solenoid Application in Packaging.
Silicone adhesive is selected all can of models such as 587,596,598,5699 or 207 for use.
Concrete grammar is: need an I shape coil rack 3 when making solenoid, it has first surface 6, second surface 5 and the 3rd surface 7 and carries enamelled wire coiling 2; Make on the central axis of coil rack 3 when a through hole 4 is installed magnetic conductor and coiling enamelled wire and be used in the coil winding machine rotating shaft, fixing.
Enamelled wire 2 is after coiling is finished on the coil rack 3, because first surface 6, second surface 5 and the 3rd surface 7 of coil rack 3 all seal, outside oil, gas, water etc. just can't enter the inside of enamelled wire coiling 2, and sealing can be realized in these three surfaces.The coating silicone adhesive forms potting layer 1 on the outer surface 8 of enamelled wire coiling 2 again.The thickness 11 of potting layer 1 all can as 0.3mm, 1.5mm, 3.0mm, 4.5mm or 5mm are thick between 0.3mm-5mm.
Introduce below and how silicone adhesive is coated in formation potting layer 1 on the outer surface 8.
