Description
Technical field
The present invention relates to a kind of magnetic core, more particularly to a kind of stable type core assembly.
Background technology
Magnetic core refers to a kind of sintering magnetic metal oxide being made up of various iron oxide mixtures.For example, manganese-zinc-iron oxygen
Body and nickel-zinc ferrite are typical magnetic core array materials.The characteristics of manganese-zinc ferrite has high magnetic permeability and high magnetic flux density,
And with more low-loss characteristic.Nickel-zinc ferrite has the characteristics such as high unit area impedance, low magnetic permeability less than hundreds of.Iron
Ferrite core is used in the coil and transformer of various electronic equipments.
A kind of sintering magnetic metal oxide that magnetic core is made up of various iron oxide mixtures, with can add in circuit
The magnetic flux density of big magnet coil magnetic circuit, reduces copper loss, to increase electromagnetic intensity, improves voltage conversion efficiency.Magnetic core
The good and bad influence for transformer of performance greatly, so, improve the emphasis that the performance of magnetic core is always studied in the industry.
Therefore, to solve the above problems, special provide a kind of new technical scheme.
The content of the invention
The present invention provides a kind of stable type core assembly.

It is U-shape structure to state the first magnetic core array and the second magnetic core array, and first magnetic core array is with the second magnetic core array formation whole magnetic core
Rectangle, the end face of first magnetic core array sets fluted, and second magnetic core array is in the groove of the first magnetic core array, institute
Stating the second magnetic core array outer wrap has insulating tape.
Further, first magnetic core array is made up of alloy material.
Further, second magnetic core array is made up of ferrite.
Further, the second magnetic core array end face diameter is less than the first magnetic core array end face diameter.
Further, it is provided with elastic component in the groove.
Further, the elastic component is elastic seal ring.
The beneficial effects of the invention are as follows:First magnetic core array and the second magnetic core array are implemented in combination with improved high current behaviour, high magnetic conductance
Rate and the high patience changed to temperature, alloy material is made to be set with ferritic so that the good wave filtering effect of magnetic core, insulation
The setting of band can improve the stability of magnetic core.
