The invention discloses a kind of magnetic core, including core body, core body includes the first magnetic core array and the second magnetic core array, first magnetic core array and the second magnetic core array are U-shape structure, it is rectangle that first magnetic core array and the second magnetic core array, which form whole magnetic core, first magnetic core array is connected with the junction of the second magnetic core array by connector, and the center on the outside of the first magnetic core array is installed with magnetic pole.The beneficial effects of the invention are as follows：The high patience that first magnetic core array and the second magnetic core array are implemented in combination with improved high current behaviour, high magnetic permeability and changed to temperature, alloy material is made to be set with ferritic, so that the good wave filtering effect of magnetic core, the setting of connection ring, can improve stability during filter core work.
Description
Technical field
The present invention relates to a kind of magnetic core, more particularly to a kind of magnetic core.
Background technology
Magnetic core：Magnetic core refers to a kind of sintering magnetic metal oxide being made up of various iron oxide mixtures.For example, manganese-
Zn ferrite and nickel-zinc ferrite are typical magnetic core array materials.Manganese-zinc ferrite has high magnetic permeability and high magnetic flux density
Feature, and with more low-loss characteristic.Nickel-zinc ferrite has the spies such as high unit area impedance, low magnetic permeability less than hundreds of
Property.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 magnetic core.
The technical solution adopted by the present invention is：
A kind of magnetic core, including core body, the core body include the first magnetic core array and the second magnetic core array, first magnetic core
Body and the second magnetic core array are U-shape structure, and the first magnetic core array and the second magnetic core array the formation whole magnetic core is rectangle, described
First magnetic core array is connected with the junction of the second magnetic core array by connector, and the center on the outside of first magnetic core array is fixed
Magnetic pole is installed.
Further, first magnetic core array is made up of alloy material.
Further, second magnetic core array is made up of ferrite.
Further, the connector is connection ring.
Further, the connection ring is made up of insulating materials.
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, connection
The setting of ring, can improve stability during filter core work.
Brief description of the drawings
The present invention is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the structural representation of the present invention.
Wherein：1st, the first magnetic core array, the 2, second magnetic core array, 3, groove, 4, connection ring, 5, magnetic pole.

In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, should
Embodiment is only used for explaining the present invention, does not constitute the restriction to protection scope of the present invention.
A kind of magnetic core as shown in Figure 1, including core body, core body include the first magnetic core array 1 and the second magnetic core array
2, the first magnetic core array 1 and the second magnetic core array 2 are U-shape structure, and the first magnetic core array 1 is with the integral magnetic core of the bodily form of the second magnetic core 2
Rectangle, the first magnetic core array 1 is connected with the junction of the second magnetic core array 2 by connection ring 4, the center in the outside of the first magnetic core array 1
Position is installed with magnetic pole 5, and connection ring 4 is made up of insulating materials, and the first magnetic core array 1 is made up of alloy material, the second magnetic core
Body 2 is made up of ferrite, and the end face diameter of the second magnetic core array 2, which is less than in the end face diameter of the first magnetic core array 1, groove 3, sets flexible
Sealing ring 4.
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, connection
The setting of ring, can improve stability during filter core work.
The above described is only a preferred embodiment of the present invention, being 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 model claimed of the invention
Enclose.
