Abstract
The utility model discloses an improved structure of a magnetic core, which comprises a C-shaped magnet base plate. The improved structure is characterized in that circular arc transition is adopted in corners of the C-shaped magnet base plate, elliptical bumping posts which are perpendicular to two horizontal sections of the C-shaped magnet base plate are respectively arranged on the two horizontal sections of the C-shaped magnet base plate, the peripheral sides of the elliptical bumping posts are matched with the two horizontal sections of the C-shaped magnet base plate, and an elliptical magnet post which is vertically placed is arranged in the middle of a vertical section of the C-shaped magnet base plate. The improved structure has the advantages of reasonable and firm structure design, good heat radiation effect, less material wastage and good flux leakage prevention effect, the integrity of the magnetic core is greatly reduced, the electromagnetic interference is reduced, and the service life of the magnetic core is prolonged.
Description
Technical field
The utility model relates to a kind of magnetic core, relates in particular to a kind of improvement structure of magnetic core.
Background technology
Present existing circular magnetic core exists radiating effect bad, spillage of material is larger, greatly reduce the globality of magnetic core, although the magnetic core of E type is convenient to wiring when the assembling electronic product simultaneously, but can not form good sealing to coil because opening is large, its material is mostly single alloy material or ferrite material, because the alloy magnetic core is high because of its magnetic permeability, in the low frequency good filtration effect, but the rising along with frequency, its inductance value decay rapidly, does not almost act in medium, high frequency; The relative alloy magnetic core of the magnetic permeability of FERRITE CORE is much lower, so inductance coefficent system is little with the frequency change impact, and filter effect is bad when low frequency, but in middle and high frequency good filtration effect.In EMI filtered, these two kinds of magnetic core filter effects all were subjected to frequency influence, and its structure is insecure, and useful life is short.
The utility model content
The purpose of this utility model is in order to make up the deficiency of prior art, and a kind of improvement structure of magnetic core is provided.
The utility model is achieved through the following technical solutions:
A kind of improvement structure of magnetic core, include C shape magnet base plate, it is characterized in that: the corner of described C shape magnet base plate all adopts arc transition, on two horizontal segments of described C shape magnet base plate, be respectively equipped with perpendicular oval bumping post, and the neighboring of oval bumping post coordinates with two horizontal segments of C shape magnet base plate, and the described C shape magnet base plate vertically middle part of section is provided with an oval magnetic column of vertically placing.
Described oval bumping post and oval magnetic column adopt respectively oxygen iron body material to make, wherein section is provided with respectively inlaid hole, in described inlaid hole, be embedded with respectively the annular guide column that alloy material is made, in the pilot hole of described annular guide column, coordinate respectively the guide pillar that aerobic iron body material is made is installed.
The structural design of the oval magnetic column that the oval bumping post by C shape magnet base plate and both ends horizontal and middle part are vertical, on the one hand in good heat dissipation effect, spillage of material is little, greatly reduce the globality of magnetic core, simultaneously can form good sealing to coil, and by oval bumping post, oval magnetic column and embedded annular guide column, the assembly that guide pillar adopts oxygen iron body material and alloy material, its magnetic-leakage preventing is effective, reduced Electromagnetic Interference, and its sound construction, extended its useful life.
The utility model has the advantages that:
The utility model reasonable in design is firm, good heat dissipation effect, and spillage of material is little, greatly reduces the globality of magnetic core, and magnetic-leakage preventing is effective simultaneously, has reduced Electromagnetic Interference, has extended its useful life.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
