Abstract
The invention discloses a filter inductor which is characterized by comprising three annular magnetic cores which overlap together and a wrapped wire which winds the three overlapped annular magnetic cores together. According to the filter inductor, sendust is adopted as a magnetic core, the three annular magnetic cores are wrapped outside the wrapped wire; the filter inductor has stable high-temperature performance, low power consumption and relatively large magnetic flux, can shorten the core size, reduce the consumption, generate a high inductance, and meet the use requirement on large inductance.
Description
Technical field
The present invention relates to a kind of filter inductance, belong to electronic technology field.
Background technology
Limited by the saturation induction density of magnetic core; Especially through under the big current conditions, magnetic core is prone to loss and heating, and the inductance value of filter inductance can't be accomplished high value usually; Some are needed the application scenario of higher value of inductance, can't satisfy user demand.
Summary of the invention
Technical problem to be solved by this invention provides a kind of filter inductance, can produce higher inductance value, satisfies the user demand to big inductance value.
For solving the problems of the technologies described above, the present invention provides a kind of filter inductance, it is characterized in that, comprises 3 toroidal cores that are superimposed and the toroidal core of 3 stacks is twined the all-in-one-piece silk-covered wire.
The material of said toroidal core is the iron sial.
Said silk-covered wire alternately passes the interior ring and the outer shroud of said toroidal core, and the toroidal core of 3 stacks is wound in one.
3 said toroidal core is big or small, shape is identical.
The beneficial effect that the present invention reached:
Filter inductance of the present invention adopts the iron sial as magnetic core, and adopts the outer wrapping wire envelope curve of 3 annular sendust cores, has stable high-temperature performance; Low in energy consumption, magnetic flux is relatively large, can dwindle the magnetic core size; Reduce the wastage, produce higher inductance value, satisfy user demand big inductance value.
Description of drawings
Fig. 1 is a filter inductance structural representation of the present invention;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the present invention is further described.Following examples only are used for technical scheme of the present invention more clearly is described, and can not limit protection scope of the present invention with this.
Like Fig. 1, shown in Figure 2, filter inductance of the present invention comprises 3 toroidal cores that are superimposed 1, and the material of toroidal core 1 is the iron sial, after 3 toroidal core 1 stacks, is wound in one by silk-covered wire 2.When silk-covered wire 2 twines, alternately pass in the ring of magnetic core ring 11 outward 12, the toroidal core 1 of 3 stacks is wound in one with ring.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from know-why of the present invention; Can also make some improvement and distortion, these improvement and distortion also should be regarded as protection scope of the present invention.
