The soft magnetism composite cores
Technical field
The utility model belongs to electrical equipment material technology field, and the soft magnetism that specifically is the instrument transformer among a kind of EMI coil that is applied to power supply, filter inductance, the CT is in conjunction with magnetic core.
Background technology
Traditional soft magnetic material magnetic core, be the soft magnetic core of homogenous material, because its intrinsic characteristic, its performance does not satisfy the requirement (comprising direct current or exchange status) of frequency end or current system, and in the middle of making, exist technology various, problems such as the part volume is big, heavyweight vehicle.
The utility model content
It is simple that the purpose of this utility model provides a kind of technology, the soft magnetism composite cores that volume is small and exquisite.Amorphous, nanocrystalline material combine magnetic core with soft magnetic material.
The technical solution of the utility model is; a kind of soft magnetism composite cores comprises the magnetic core of nanocrystalline material formation and the magnetic core that Ferrite Material constitutes, and it is characterized in that; nanocrystalline magnet core is sleeved on along vertical axial in the cavity of FERRITE CORE, and these two kinds of magnetic cores are installed in the protection box.
As another kind of implementation of the present utility model, described nanocrystalline magnet core also can stack setting with FERRITE CORE, and these two kinds of magnetic cores are installed in the protection box.
The above-described magnetic core that is made of Ferrite Material also can be the magnetic core that is made of the iron based amorphous material.
Above-described protection box is a plastic cement protection box.
The utility model is combined with nanocrystalline magnet core by amorphous magnetic core or FERRITE CORE, can satisfy low-and high-frequency end performance requirement, also can satisfy the performance requirement of alternating current-direct current, reduce technology, reduced volume, alleviated weight, most importantly reduced production cost.

Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Referring to Fig. 1, Fig. 6 be one of embodiment of the present utility model, two soft magnetic material schematic diagram.The utility model main purpose is to utilize the different magnetic property of two kinds of different soft magnetic materials (iron based amorphous material, nanocrystalline material, Ferrite Material), form a kind of can meet that frequency is that EMI requires between the 1KHZ--1MHZ in conjunction with magnetic core.Label shown in the figure 1 or 11 is a nanocrystalline material, and 2 or 22 is Ferrite Material or iron based amorphous material.These two kinds of soft magnetic materials all are according to the difference of using electric property, carry out accurate in various degree Technology for Heating Processing, and institute reaches corresponding numerical value.
Referring to Fig. 2, Fig. 7 be one of embodiment of the present utility model, two building block principle schematic diagram.According to the needs of application site, nanocrystalline magnet core 1 can be sleeved in the cavity of FERRITE CORE or iron based amorphous magnetic core 2 vertically, or nanocrystalline magnet core 1 overlays FERRITE CORE or iron based amorphous magnetic core 2 tops.
Referring to Fig. 3, Fig. 4 and Fig. 8, Fig. 9 be one of embodiment of the present utility model, two package assembly schematic diagram.3 or 33 is plastic cement protection box, two kinds of soft magnetic materials is put into separately the plastic cement of usefulness is protected in the box.This plastic cement protection box comprises various ways.
Referring to Fig. 5, Figure 10 be one of embodiment of the present utility model, two fixing protection schematic diagrames.Protect corresponding the closing of box to build in plastic cement, make material be subjected to certain protection, can directly on the protection box, do coiling processing.This paper does not do one by one to be enumerated.
