Description
Technical field
The present invention relates to a kind of magnetic core, be specifically related to a kind of combined anti-interference magnetic core.
Background technology
Magnetic core refers to a kind of sintering magnetic metal oxide being made up of various iron oxide mixture, is widely used in all kinds of magnetic devices such as transformator, high frequency magnetic amplifier, smoothing choke.Development along with electronics industry, traditional single magnetic core has been no longer able to fully meet the market demand, if able to get up to use by multiple core combination, just can increase core volume makes its scope of application wider, but how to ensure that the interference free performance of combined magnet core is to perplex a difficult problem in the industry.
Summary of the invention
For solving the deficiencies in the prior art, it is an object of the invention to provide a kind of anti-interference magnetic core that can be used alone, can also be applied in combination.
In order to realize above-mentioned target, the present invention adopts the following technical scheme that:
A kind of combined anti-interference magnetic core, including two magnetic core monomers, described magnetic core monomer includes core body and the magnetic post being shaped in core body；Described core body includes: integrated base and constitute three sidewalls of semi-surrounding structure with base, and described magnetic post is arranged on base and all to leave coiling space, described magnetic post and three sidewalls between magnetic post and three sidewalls contour；It is provided with connection post and the attachment structure connecting two magnetic core monomers on described magnetic post accordingly, can be contained in attachment structure after the dismounting of described connection post.
Aforementioned magnetic post is cylindrical, is arranged at the marginal position of base and equal with the distance between three sidewalls.
Aforementioned lateral wall includes: the first side wall being parallel to each other and the second sidewall, connection the first side wall and the 3rd sidewall of the second sidewall, the internal face of the close magnetic post of described 3rd sidewall is arc.
Aforementioned connection post rivets or is buckled on the sidewall of described magnetic post, and described attachment structure is the groove accommodating and connecting post.
Further, a cylinder shape groove is formed in aforementioned magnetic post along its length to improve interference free performance.
The invention have benefit that: the magnetic core of the present invention can be used alone and can also be applied in combination, the scope of application is wider, design ingenious, on magnetic post can the coil turn of coiling more, thus properties of product are more remarkable, and, unique structure gives the interference free performance that product is good, effectively inhibiting High-frequency Interference, research shows, arranges groove along its length and can also improve the interference free performance of magnetic core further in magnetic post.
Accompanying drawing explanation
Fig. 1 is the structural representation of the specific embodiment of a kind of combined anti-interference magnetic core of the present invention.
The implication of reference in figure: 1, magnetic core monomer, 2, magnetic post, 3, base, 4, the first side wall, the 5, second sidewall, the 6, the 3rd sidewall, 7, connect post, 8, attachment structure, 9, cylinder shape groove.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention made concrete introduction.
Seeing Fig. 1, the combined anti-interference magnetic core of one of the present invention, including two magnetic core monomers 1, specifically, each magnetic core monomer 1 all includes core body and the magnetic post 2 being shaped in core body.Wherein, core body includes: integrated base 3 and constitute three sidewalls of semi-surrounding structure with base 3, and magnetic post 2 is arranged on base 3 and all leaves coiling space between magnetic post 2 and three sidewalls, and magnetic post 2 is contour with three sidewalls.So, magnetic post 2 is positioned in a semi-surrounding structure, compared to the product of traditional structure, has good interference free performance.In order to two magnetic core monomers 1 are combined connection, magnetic post 2 is provided with connection post 7 and attachment structure 8 accordingly that connect two magnetic core monomers 1, during combination, the post 7 that connects of first magnetic core monomer 1 coordinates with the attachment structure 8 of second magnetic core monomer 1, and the post 7 that connects of second magnetic core monomer 1 coordinates with the attachment structure 8 of first magnetic core monomer 1, two semi-surrounding structures just constitute a full encirclement structure, and interference free performance is further improved.Dexterously, can be contained in attachment structure 8 after connecting post 7 dismounting, so, when magnetic core monomer 1 is used alone, connection post 7 to be pulled down and is placed in attachment structure 8, the surface of magnetic post 2 is also smooth, it is ensured that its performance is unaffected.
Preferably, magnetic post 2 is cylindrical, is arranged at the marginal position of base 3 and equal with the distance between three sidewalls.As it is shown in figure 1, sidewall includes: the first side wall 4 being parallel to each other and the second sidewall 5, connection the first side wall 4 and the 3rd sidewall 6 of the second sidewall 5, wherein the internal face of the close magnetic post 2 of the 3rd sidewall 6 is arc.The internal face of arc makes the space between magnetic post 2 and sidewall become big, and namely " window " increases, it is possible to the coil turn of coiling is also the most more, is favorably improved the performance of product.
As a kind of concrete structure, connect post 7 and rivet or be buckled on the sidewall of described magnetic post 2, and attachment structure 8 is the groove accommodating and connecting post 7.
Further, forming a cylinder shape groove 9 in magnetic post 2 along its length, research proves, this structure can improve the interference free performance of magnetic core further, the when of being applied on electronic product, it is possible to significantly improve the anti-electromagnetic interference capability of electronic product, effectively inhibit High-frequency Interference.It should be strongly noted that this cylinder shape groove 9 is not communicated with previously described attachment structure 8.
The ultimate principle of the present invention, principal character and advantage have more than been shown and described.Skilled person will appreciate that of the industry, above-described embodiment limits the present invention, the technical scheme that the mode of all employing equivalents or equivalent transformation is obtained the most in any form, all falls within protection scope of the present invention.
