Description
Technical field
The present invention relates to a kind of magnetic core, more particularly to a kind of core structure.
Background technology
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 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.Manganese-zinc ferrite has the characteristics of high magnetic permeability and high magnetic flux density,
And in the frequency less than 1MHz, there is more low-loss characteristic.Nickel-zinc ferrite has high unit area impedance, less than hundreds of
The characteristic such as low magnetic permeability, and also produced compared with low-loss etc. in the frequency higher than 1MHz.FERRITE CORE is set for various electronics
In standby coil and transformer.
At present, the structure design of magnetic core is not reasonable, is laid out inadequate science, and magnetic amount used is more in magnetic core, increase
The consumption of magnetic resource, improve the cost of raw material.
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 core structure.
The technical solution adopted by the present invention is：
A kind of core structure, including core body, the core body include the first magnetic core array and the second magnetic core array, and described first
Magnetic core array and the second magnetic core array are U-shape structure, and it is rectangle that first magnetic core array and the second magnetic core array, which form whole magnetic core,
The end face setting of first magnetic core array is fluted, and second magnetic core array is in the groove of the first magnetic core array, and described second
Center on the outside of magnetic core array is provided with magnetic pole, and coil is wound with first magnetic core array.
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 are made and ferritic setting so that the good wave filtering effect of magnetic core, improve
The setting of the stability of work, magnetic pole and coil, improve the security of magnetic core in use.

The center in the outside of the second magnetic core array 2 is provided with magnetic pole 5, coil 6 is wound with the first magnetic core array 1, the first magnetic core array 1 is by closing
Golden material is made, and the second magnetic core array 2 is made up of ferrite, and it is straight that the end face diameter of the second magnetic core array 2 is less than the end face of the first magnetic core array 1
Footpath, elastic seal ring 4 is provided with groove 3.
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 are made and ferritic setting so that the good wave filtering effect of magnetic core, improve
The setting of the stability of work, magnetic pole and coil, improve the security of magnetic core in use.
The above described is only a preferred embodiment of the present invention, it is not the limit for making any other form to the present invention
System, and any modification made according to technical spirit of the invention or equivalent variations, still fall within present invention model claimed
Enclose.
