Abstract
The utility model discloses an ultra-miniature SMD (Surface Mounted Device) power inductor which structurally comprises a top part, a magnetic core main body, a bottom part and a coil, wherein the top part and the bottom part are both of ferrite core layers; a metal electrode slice is arranged on the bottom part; a layer of ferrite core is plated on the surface of the metal electrode slice; the coil is wound on the exterior of the magnetic core main body; a magnetic rubber layer is coated on the surface of the coil; two pins of the coil are respectively introduced from corresponding slots of the metal electrode slice on the bottom part. The ultra-miniature SMD power inductor has the beneficial effects that the magnetic rubber layer is seamlessly jointed with the coil; the buzzing generated during the working process of the products is effectively reduced; due to the unique magnetic shielding structure and the design of the metal electrode slice on the bottom part, the product has ultrahigh anti-falling capability which is more than 5 times of the anti-falling capability of the traditional inductor; guarantee is provided for the stable working of electronic products.
Description
Technical field
The utility model belongs to inductor field, is specifically related to a kind of superminiature SMD power inductance.
Background technology
Along with developing rapidly of science and technology, the size of the various mobile digital products including mobile phone is more and more less.Due to the variation of environment bring to electromagnetic radiation, the interference that intersects is more and more stricter with electromagnetic pollution control, inductor is taken on important absorption surging function in circuit, and the anti-drop ability of power inductor wherein, the requirement that EMI characteristic also can not meet market.The small-size slice power inductance device of Vehicles Collected from Market is not mostly integrated structure, there is the shortcomings such as inductance value leakage field on the low side, easy, poor reliability, and the bad Difficulty of EMI characteristic, simultaneously, in the time producing product, can produce buzzer, production environment is produced to larger noise pollution.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of superminiature SMD power inductance, adopt unique magnet shielding structure design, by the seamless combination of magnetic glue and coil, the buzzer having produced while effectively having reduced product work has advantages of that anti-EMI, leakage field are few, good reliability simultaneously.
The technical solution adopted in the utility model is as follows: a kind of superminiature SMD power inductance, comprise top, magnetic core main body, bottom, coil, top and bottom are ferrite magnetic sandwich layer, bottom is provided with metal electrode film, metal electrode film surface is coated with one deck FERRITE CORE, described magnetic core main body is around with coil, and the surface of coil scribbles magnetic glue-line, and two pins of described coil are drawn by the respective slot of the metal electrode film of bottom respectively.
Two pins of described coil are welded on the metal electrode film of bottom.
Described magnetic glue-line is to be uniformly mixed the rear magnetic glue-line forming by epoxy resin and Magnaglo by weight 1:1.
The beneficial effects of the utility model are: the seamless combination of magnetic glue-line and coil, the buzzer having produced while effectively having reduced product work, the sheet metal electrode design of bottom, make product there is superpower anti-drop ability, fall capability improving more than 5 times compared with traditional electrical induction reactance, for electronic product steady operation provides guarantee.Adopt closed magnetic circuit design, leakage field is few simultaneously, and anti-EMI ability is strong, and shielding can reach 30-80dB.
Accompanying drawing explanation
Fig. 1 is stereogram of the present utility model;
Fig. 2 is side schematic view of the present utility model.
In figure, 1 is top, and 2 is magnetic core main body, and 3 is bottom, and 4 is magnetic glue-line, and 5 is pin.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further:
As depicted in figs. 1 and 2, superminiature SMD power inductance, comprise top 1, magnetic core main body 2, bottom 3, top 1 and bottom 3 are ferrite magnetic sandwich layer, magnetic core main body 2 is around with coil, the surface of coil scribbles magnetic glue-line 4, and bottom metal electrode sheet surface is coated with one deck FERRITE CORE, and two pins 5 of described coil are drawn by the respective slot of bottom metal electrode sheet respectively.
Two pins 5 of coil are welded on the sheet metal 3 of bottom.
Magnetic glue-line 4 is to be uniformly mixed the rear magnetic glue-line forming by epoxy resin and Magnaglo by weight 1:1.
The utility model is simple in structure, magnetic epoxy glue is coated on inductance coil top layer, reach the effect of closing magnetic, few, the anti-inductance performance of leakage field is strong, and the sheet metal electrode design of bottom makes product have superpower anti-drop ability, adopt closed magnetic circuit design simultaneously, leakage field is few, and anti-EMI ability is strong, and shielding can reach 30-80dB.
