Abstract
The utility model provides a ferrous metal nanocrystalline high frequency magnetic core, which comprises a ring-shaped magnetic core body which is sealed in a protection body. The utility model is characterized in that the magnetic core body is formed through the tight winding of ferrous metal nanocrystalline magnetically-soft alloy strips. The metal nanocrystalline magnetically-soft alloy adopts the strips whose thickness is 0.018-0.02 mm and surface ruggedness is small or equal to 2.2mum. The ferrous metal nanocrystalline high frequency magnetic core of the utility model which is winded by ferrous metal nanocrystalline magnetically-soft alloy strips has high single-turn electric inductance value, simple art, light size and low price, which can replace the magnetic core in cobalt-base non-crystalline material.
Description
Technical field: the utility model relates to magnetic element, refers to the high frequency magnetic core that communication electron trade power supply is used especially.
Background technology:
The development of modern communications technology is also had higher requirement to magnetic induction part.Traditional soft magnetic materials such as silicon steel sheet originally, permalloy, ferrite are replaced by amorphous soft-magnetic alloy.Now external communication is extensively adopted cobalt base amorphous material with high frequency magnetic core, but this material price costliness, complex process.
Summary of the invention:
The iron based nano crystal band adopts brand-new high speed condensation production technology because of it, make its microstructure be different from traditional metal alloy compositions fully and have a series of special premium properties, as good magnetic property, high intensity, hardness, resistance to wear and good pliability, surface smoothness etc., and technology is simple, cheap.
The purpose of this utility model is to propose a kind of toroidal core that adopts the iron based nano crystal band to make, the magnetic core of cost an arm and a leg to substitute, the cobalt base amorphous material of complex process being made.
A kind of iron based nano crystal high frequency magnetic core of the present utility model comprises that one is closed in the ring-shaped magnetic core body of protection in the box, it is characterized in that described magnetic core array by the Fe-based nanocrystalline magnetically soft alloy roll of strip around forming.
The thickness of described Fe-based nanocrystalline magnetically soft alloy band can be as thin as 0.018-0.02mm, surfacing, and therefore surface roughness≤2.2 μ m, and single turn inductance value height can reel very closely, and volume is done very for a short time.
Iron based nano crystal high frequency magnetic core of the present utility model, owing to adopt the Fe-based nanocrystalline magnetically soft alloy roll of strip around forming, technology is simple, volume is little, price is low, can realize microminiaturization, replaces the magnetic core of cobalt base amorphous material.
Description of drawings:
Fig. 1 is the schematic diagram of iron based nano crystal high frequency magnetic core of the present utility model.
Embodiment:
An embodiment of the present utility model as shown in Figure 1.Among the figure: 1 magnetic core array, 2 protection boxes, 3 silica gel.
Wherein magnetic core array 1 by the Fe-based nanocrystalline magnetically soft alloy roll of strip around forming.Because adopting thickness is the Fe-based nanocrystalline magnetically soft alloy band of 0.018-0.02mm, its smooth surface, its surface irregularity degree≤2.2 μ m, pliability is good, single turn inductance value height.The physical dimension of product has reached internal diameter≤2.3mm at present, external diameter≤3.8mm, highly≤1.6mm.
