Abstract
A high-strength iron core for a mutual inductor comprises a coil turn ring sealed in an insulation outer shell, and is characterized in that the outer circumferential surface, the inner circumferential surface, the upper surface and the lower surface of the coil turn ring are respectively provided with an insulation solidification protective layer, and the insulation solidification protective layers in the intersection positions of the outer circumferential surface, the upper surface and the lower surface are of a round corner structure. The high-strength iron core for the mutual inductor has the advantages of being simple in structure, low in cost, small in size, good in wholeness and stability, convenient to machine, and good in signal shielding effect.
Description
Technical field
The utility model belongs to technical field of electronic devices, relates to the high strength iron core that a kind of instrument transformer is used, and particularly has the iron core of insulation curing protective coat.
Background technology
Iron core comprises the ring-type iron core formed by coil winding, and in prior art, the insulation of iron core adopts plastic casing to wrap up and sealing the ring-type iron core, has played certain insulation and curing effect.But the protection of moulding shell is very limited, and the iron core stability is poor, and, a little less than this structure is highly brittle, the time has been grown the easy aging fracture of plastics, and antioxygenic property is poor, and useful life is short.
Summary of the invention
The utility model, for addressing the deficiencies of the prior art, has designed the high strength iron core that a kind of instrument transformer is used.
The technical solution of the utility model is; the high strength iron core that a kind of instrument transformer is used; comprise the coil turn ring be enclosed in insulation crust; key is: be provided with one deck insulation curing protective coat at the outer surface of coil turn ring, interior perimeter surface, upper surface and lower surface, and the insulation curing protective coat of outer surface and upper surface, lower surface intersection is fillet structure.
The thickness of the insulation curing protective coat of described coil turn ring outer surface, upper surface and lower surface is 0.3～0.5mm.
In described coil turn ring, the thickness of the insulation curing protective coat of perimeter surface is 0.08～0.1mm.
The beneficial effects of the utility model are simple in structure, with low cost, and volume is little, and globality and good stability are easy to process.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
1 represents the coil turn ring, 2 representative insulation curing protective coats, and 3 represent insulation crust.
Embodiment
The high strength iron core that a kind of instrument transformer is used; comprise the coil turn ring 1 be enclosed in insulation crust 3; key is: be provided with one deck insulation curing protective coat 2 at the outer surface of coil turn ring 1, interior perimeter surface, upper surface and lower surface, and the insulation curing protective coat 2 of outer surface and upper surface, lower surface intersection is fillet structure.
The thickness of the insulation curing protective coat 2 of described coil turn ring 1 outer surface, upper surface and lower surface is 0.3～0.5mm.
The thickness of the insulation curing protective coat 2 of described coil turn ring 1 interior perimeter surface is 0.08～0.1mm.
The utility model in the specific implementation; at first coil is wound in to ring-type; after heat treatment, with epoxy resin, applied; in order to guarantee certain intensity; insulation curing protective coat 2 at coil turn ring 1 outer surface, upper surface and lower surface wants thicker; the insulation curing protective coat 2 of inner peripheral surface is thinner, and attractive in appearance for product, to the external corners place of iron core carrying out the fillet processing.
