Abstract

The invention discloses a kind of stable type core assembly, 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, the end face of first magnetic core array sets fluted, and the second magnetic core array is in the groove of the first magnetic core array, and the second magnetic core array outer wrap has insulating tape.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 into 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 insulating tape can improve the stability of magnetic core.

Description

A kind of stable type core assembly
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.
The technical solution adopted by the present invention is:
A kind of stable type core assembly, including core body, the core body include the first magnetic core array and the second magnetic core array, institute 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.
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, insulating tape.
Embodiment
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 stable type core assembly as shown in Figure 1, including core body, core body include the He of the first magnetic core array 1 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 formed with the body of the second magnetic core 2 Whole magnetic core is rectangle, and the end face of the first magnetic core array 1 sets fluted 3, and the second magnetic core array 2 is recessed located at the first magnetic core array 1 In groove 3, the outer wrap of the second magnetic core array 2 has insulating tape 4, and the first magnetic core array 1 is made up of alloy material, and the second magnetic core array 2 is by iron Oxysome is made, and the end face diameter of the second magnetic core array 2 is less than the end face diameter of the first magnetic core array 1.
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.
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.
