Abstract

The utility model relates to an electronic component, in particular to an annular filter inductor which can generate high induction, and comprises three annular overlaid Fe-Si-Al iron cores and two groups of silk-covered wires wound on the iron cores, wherein the two groups of silk-covered wires pass through the inner rings and the outer rings of the Fe-Si-Al iron cores in a staggered way, to form two groups of wire coils on the Fe-Si-Al iron cores, and the spiral directions of the wire coils are opposite. As the three overlaid Fe-Si-Al iron cores are arranged, and the two groups of silk-covered wires pass through the inner rings and the outer rings of the Fe-Si-Al iron cores in the staggered way, the annular filter inductor according to the utility model can generate larger induction, has the high voltage resistance function, and is not easy to damage.

Description

Loop filtering inductance

Technical field

The utility model relates to a kind of loop filtering inductance, belongs to electronic devices and components field.

Background technology

Inductance is conventional electronic devices and components, and it is low that existing inductance generally produces inductance, does not have high voltage bearing effect.

Utility model content

Technical problem to be solved in the utility model is: a kind of loop filtering inductance high pressure resistant, good wave filtering effect that produces is provided.

The utility model solves technical scheme that its technical problem adopts: loop filtering inductance, comprise iron core and be wrapped in the silk-covered wire on this iron core, described iron core is three annular iron sial iron cores that are superimposed, described silk-covered wire has two groups, and all staggered interior ring and outer shroud through iron sial iron core are wound in two groups of coils that the hand of spiral is contrary on iron sial iron core.

As preferably, the end of described silk-covered wire is provided with terminals, on these terminals, is in series with magnetic bead.

As preferably, described iron sial iron core is positive annular.

Loop filtering inductance of the present utility model, owing to being provided with three annular iron sial iron cores that are superimposed, described silk-covered wire has two groups, and all staggered interior ring and outer shrouds through iron sial iron core, the inductance that loop filtering inductance is produced is large, has high pressure resistant effect, is not easy to damage; Because the end of described silk-covered wire is provided with terminals, on these terminals, be in series with magnetic bead, in the time that AC current frequency is high, play good High frequency filter effect.

Accompanying drawing explanation

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

Embodiment

For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.

With reference to Fig. 1, this embodiment is by the following technical solutions: loop filtering inductance, comprise iron core and be wrapped in the silk-covered wire 2 on this iron core, described iron core is three annular iron sial iron cores 1 that are superimposed, described silk-covered wire 2 has two groups, and all staggered interior ring and outer shroud through iron sial iron core 1 are wound in two groups of coils that the hand of spiral is contrary on iron sial iron core 1.Loop filtering inductance of the present utility model, owing to being provided with three annular iron sial iron cores 1 that are superimposed, described silk-covered wire 2 has two groups, and all staggered interior ring and outer shrouds through iron sial iron core 1, the inductance that loop filtering inductance is produced is large, has high pressure resistant effect, is not easy to damage.

End that it should be noted that described silk-covered wire 2 is provided with terminals 3, on these terminals 3, is in series with magnetic bead 4.Because the end of described silk-covered wire 2 is provided with terminals 3, on these terminals 3, be in series with magnetic bead 4, in the time that AC current frequency is high, play good High frequency filter effect.

In addition, described iron sial iron core 1 is positive annular.

This is specifically implemented owing to being provided with three annular iron sial iron cores that are superimposed, and described silk-covered wire has two groups, and all interlocks through interior ring and the outer shroud of iron sial iron core, and the inductance that loop filtering inductance is produced is large, has high pressure resistant effect, is not easy to damage; Because the end of described silk-covered wire is provided with terminals, on these terminals, be in series with magnetic bead, in the time that AC current frequency is high, play good High frequency filter effect.

More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
