Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
- 4 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of magnetic glue inductor of high-efficiency anti-magnetic interference,
Including magnetic core 1, coil 2, gasket 4, the first magnetic screen column 6 and the second magnetic screen column 7, the coil 2 is wound on magnetic core 1, institute
It states 1 both ends of magnetic core and is fixed with gasket 4, the peripheral seal of the coil 2 is enclosed with Magnetic adhesive 3, is set in the first magnetic screen column 6
There is cylinder straight slot 8, for the magnetic core 1 with 2 inlay card of coil in cylinder straight slot 8, described first magnetic screen column, 6 one end is equipped with second
Magnetic screen column 7, the second magnetic screen column 7 is interior to be equipped with through-hole 9, and the through-hole 9 connects cylinder straight slot 8, second magnetic screen
7 end surface of column is equipped with pin 10, and 2 terminals of coil are electrically connected across through-hole 9 with pin 10.
1 material of magnetic core is ferrite, and the first magnetic screen column 6 and 7 material of the second magnetic screen column are permalloy.
Outside the coil 2 coatings are coated with around one layer of iron sheet 5,5 internal layer of iron sheet.
The first magnetic screen column 6 and 7 junction of the second magnetic screen column are integrally formed, the first magnetic screen column 6 and the
It is circular arc chamfering shape at the connection molding of two magnetic screen columns 7.
The electrode of the magnetic core 1 is metallic electrode.
Operation principle：By the magnetic core 1 and coil 2 of setting and the Magnetic adhesive 3 of 2 outer cladding of coil, as magnetic glue inductor
Basic building block, by 1 electrode metallization of magnetic core, convenient for enhancing the intensity of magnetic core 1, improving the drop resistant ability of magnetic core 1, passing through
First shielding column 6 and secondary shielding column 7 of the permalloy material of setting, and the first shielding column 6 and 7 one of secondary shielding column into
Type, and be arc-shaped at molding, when contacting external magnetic field.Since shielding column magnetic permeability μ is more much bigger than air magnetic permeability mu, so absolutely
Most of magnetic field line passes through out of shielding column wall, and shields in the cavity of column, and magnetic induction line is seldom.This has just reached magnetic cup
