Abstract
The utility model discloses a kind of high pressure resistant common mode filtering inductor, it comprise skeleton, two around the coil windings on skeleton, the magnetic core be enclosed within for a pair in skeleton and two coil windings, one to be connected on magnetic core and for the iron clamp that clamps two magnetic cores and four contact pins be connected to bottom skeleton, two coil windings upper ends and this is to being coated with the binding agent be made up of epoxy resin between magnetic core.The utility model has the advantage of: under the prerequisite of high-voltage breakdown, can not greatly can increase the number of turns of coil windings in guarantee, thus greatly improve the properties of product of common mode filtering inductor.
Description
Technical field
The utility model relates to a kind of electronic devices and components, particularly a kind of high pressure resistant common mode filtering inductor.
Background technology
Along with power supply product high frequency, miniaturized development, common mode filtering inductor itself, as safety device, has also carried out continuous optimization at volume size and configuration aspects.Existing common mode filtering inductor, normally on skeleton, separately identical, that phase place the is contrary coil windings of winding two groups of numbers of turn defines inductance coil, then a pair magnetic core to be enclosed within skeleton and to fix with iron clamp.In order to prevent the high-voltage breakdown of common mode filtering inductor, between coil windings and magnetic core, generally all can remain with enough large safe distance, but the number of turns of coil windings will be caused so on the low side, thus greatly can affect the properties of product of common mode filtering inductor.
Utility model content
The technical problems to be solved in the utility model is, providing a kind of under the prerequisite of high-voltage breakdown, can not can increase the number of turns of coil windings greatly in guarantee, thus the common mode filtering inductor of greatly enhancing product performance.
For solving the problems of the technologies described above, the utility model provides and a kind ofly adopts the high pressure resistant common mode filtering inductor of following structure: comprise skeleton, two around the coil windings on skeleton, the magnetic core be enclosed within for a pair in skeleton and two coil windings, one to be connected on magnetic core and for the iron clamp that clamps two magnetic cores and four contact pins be connected to bottom skeleton, wherein, two coil windings upper ends and this is to being coated with the binding agent be made up of epoxy resin between magnetic core.
After adopting said structure, the utility model has the following advantages: because the high pressure resistant common mode filtering inductor of the utility model is coated with the binding agent be made up of epoxy resin between two coil windings upper ends and a pair magnetic core, and epoxy resin has the dielectric features of height, therefore be just that the number of turns of coil windings is more and cause the distance between coil windings upper end and magnetic core less, under the insulating effect of epoxy resin, the high pressure resistant common mode filtering inductor of the utility model also can accomplish high-insulation between coil windings and magnetic core, and after the number of turns increase of coil windings, the properties of product of the high pressure resistant common mode filtering inductor of the utility model then obtain and greatly improve.
Accompanying drawing explanation
Fig. 1 is the construction profile schematic diagram of the high pressure resistant common mode filtering inductor of the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the high pressure resistant common mode filtering inductor of the utility model is described in further detail.
As shown in Figure 1, in this embodiment, the high pressure resistant common mode filtering inductor of the utility model comprises 1, two, skeleton and to be connected on magnetic core 3 and iron clamp 4 and four for clamping two magnetic cores 3 is connected to contact pin 5, two coil windings 2 upper ends bottom skeleton 1 and this is to being coated with the binding agent 6 be made up of epoxy resin between magnetic core 3 around the coil windings 2 on skeleton 1, the magnetic core 3, be enclosed within for a pair in skeleton 1 and two coil windings 2.
Above-described embodiment is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection range that the utility model claims determine.
