Abstract
The utility model discloses an electrical inductance structure. The electrical inductance structure comprises a shell. The shell is in a ring-shaped structure. The outer ring surface of the shell is evenly provided with a plurality of stop pieces. The outer side of the shell is provided with coils in a winding mode. The inner portion of the shell is in a hollow structure and is provided with an iron core. The outer side of the coils is provided with an alcoholic varnish layer. By means of the stop pieces in the outer ring of the shell, the coils can be arranged orderly. The coils are packed into a whole by the alcoholic varnish layer in the outer side of the coils, and therefore the displacement of the coils is prevented. Meanwhile, the insulativity of the coils is better.
Description
Technical field
The utility model relates to a kind of induction structure, belongs to the inductance technical field.
Background technology
The inductance outer felt is wound with coil, and the surface group of coil is wanted good insulation property, and outside common inductance coil was exposed to, coil was at random easily, and its insulating barrier weares and teares easily simultaneously, affects the serviceability of inductance.
Summary of the invention
The utility model is for providing a kind of induction structure, makes on the inductance insulation property of coil better, and coil configuration is not at random.
For realizing this purpose, the structure that the utility model adopts is: a kind of induction structure comprises housing, described housing is loop configuration, and enclosure interior is hollow-core construction, in be provided with iron core, be wound with the coil that enamelled wire forms on the housing, the coil outside is coated with the varnish layer.
The outer ring surface of described housing is placed with a plurality of blocks.
Described varnish layer is the dipping enamelled coating.
Its beneficial effect is: the block on the housing outer shroud can make coil arrangement orderly, and the varnish layer in the coil outside is rolled into coil as a whole, prevents coil displacements, makes simultaneously the insulation property of coil better.
Description of drawings
Fig. 1 is the utility model broken section structure chart.
Embodiment
Disclosed all features in this specification, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.
Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
As shown in Figure 1, a kind of induction structure comprises housing 1, described housing 1 is hollow loop configuration, be provided with iron core 5 in the housing 1, housing 1 outer felt is wound with many group coils 3, and housing 1 is provided with a plurality of blocks 2, block 2 separates coil 3 in order, coil 3 outsides are coated with one deck varnish layer 4, and used varnish layer 4 is the dipping enamelled coating, and varnish layer 4 becomes an integral body with coil 3 parcels, prevent that coil 3 is at random, increased simultaneously the insulation property of coil 3.
