Abstract
The utility model discloses an inductor which mainly comprises a magnetic core and a coil which is wound on the magnetic core, wherein a soft shielding cover with magnetism is arranged on the outer side of the coil. Compared with a traditional inductor which is coated by magnetic glue and adopts a rigidness shielding case structure, the inductor is simple in production craft, small in equipment investment, high in good product rate and wide in generality. When the inductor is used, production processing is reduced, the inductance parameter is easily controlled, and the shape of the shielding case can be changed along with the packed coil.
Description
Technical field
The utility model relates to a kind of inductor, belongs to the new electronic component technical field.
Background technology
The inductor of open-flux structure does not have radome, so other circuit and components and parts work can be disturbed in the magnetic field that produces when inductor is worked, causes whole product function to be affected.Occur for fear of above-mentioned situation, the inductor that uses on the market at present substantially all is magnetic screen type inductor, some factory applies magnetic glue in inductor surface, but its technique is complicated, function of glue coating thickness is difficult to control, and glue also can give out pernicious gas, and human body and environment are worked the mischief.Some factory takes to increase at inductor the mode of a metallic shield, existing radome all is to make with Ferrite Material, but the ferrite radome is large on inductance electrical parameter impact variation, produce required processing procedure long, poor product quality, and because traditional ferrite radome is rigid structure, so assembling is inconvenient, production efficiency is low, and cost is high.
Summary of the invention
For addressing the above problem, it is a kind of simple in structure that the utility model provides, and effectively reduces the inductor that disturbs.
The utility model is that the technical scheme that its problem of solution adopts is:
A kind of inductor, mainly comprise magnetic core and be wound on coil on the magnetic core, the described coil outside is provided with soft quality and magnetic radome, make required specification and shape through baking-curing, especially, for the characteristics of the different use occasions of reply inductor, such as high temperature or the larger place of humidity ratio, can add some corresponding compositions, make product more durable.
Described radome has certain flexibility, and it can be made into annulus or rectangular sleeve and be located on the coil according to the true form of inductor, certainly can also be made into sheet or band shape, and be wound on the coil, makes the versatility of radome wider.
The beneficial effects of the utility model are:
1, compare with the inductor that magnetic glue applies with traditional employing rigidity shielding case structure, production technology is simple, and equipment investment is few;
Can reduce procedure for producing when 2, using, inductance parameters is more easy to control, and yields is high;
3, versatility is wide, and the radome shape can be with the alteration of form of wrapped coil.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is overall structure figure of the present utility model.
Embodiment
A kind of inductor as shown in Figure 1, mainly comprise magnetic core 1 and be wound on coil 2 on the magnetic core 1, described coil 2 outsides are provided with the radome 3 that is mixed by Ferrite Material and resin material, and radome 3 wraps the open-flux path inductance, form a closed magnetic circuit.After Ferrite Material and resin material mix according to a certain percentage, through baking-curing, make required specification and shape, resin material can adopt epoxy resin, phenolic resins or silicones etc.Especially, for the characteristics of the different use occasions of reply inductor, such as high temperature or the larger place of humidity ratio, can add some corresponding compositions, make product more durable.
Radome 3 can reduce inductor to the interference of other components and parts, it has simultaneously flexibility and is with magnetic characteristics, make the versatility of radome wider, can be made into annulus or rectangular sleeve according to the true form of inductor is located on the coil, certainly can also be made into sheet or band shape, and be wound on the coil, can use in case of necessity sticker to be fixed.
The utility model is compared with the inductor that magnetic glue applies with traditional employing rigidity shielding case structure, and production technology is simple, and equipment investment is few; Can reduce procedure for producing during use, inductance parameters is more easy to control, and yields is high; Versatility is wide, because it has flexibility, so the radome shape can be with the alteration of form of wrapped coil.
At aspect of performance, the inductor that is provided with radome is compared with existing open-flux path inductor, and leakage field is low, and D.C. resistance is low, and Electro Magnetic Compatibility and anti-electromagnetic interference are better; And the utility model is compared with the inductor of existing magnetic shield structure, and its inductance value tolerance reduces by 5 ~ 10%, anti-current boost 15 ~ 30%.
Above specification is described, only is principle of the present utility model and embodiment, everyly carries out any simple modification and variation according to essence of the present utility model, all belongs within the desired protection range of the utility model.
