Abstract
The invention discloses a combined type anti-interference magnetic core which comprises two single magnetic core bodies. Each single magnetic core body comprises a magnetic core body and a magnetic cylinder integrally formed on the magnetic core body. Each magnetic core body comprises an integrally-formed base and three side walls forming a semi-enclosure structure with the base. The magnetic cylinders are arranged on the bases, and winding gaps are reserved between the magnetic cylinders and the three side walls. Each magnetic cylinder is equal to the corresponding three side walls in height. The magnetic cylinders are correspondingly provided with connecting columns and connecting structures connecting the two single magnetic core bodies. The connecting columns after being dismantled can be contained in the connecting structures. The combined type anti-interference magnetic core has the advantages of being capable of being used individually or in a combined mode, wider in application range and ingenious in design; more coils can be wounded around the magnetic cylinders, and therefore the product performance is more excellent; moreover, due to the unique structure, the magnetic core has the good anti-interference performance, and high-frequency interference is effectively restrained; the research shows that the anti-interference performance of the magnetic core can be further improved due to grooves formed in the magnetic cylinders in the length direction.
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 by a kind of sintering magnetic metal oxide of various iron oxide compositions of mixtures, is widely used in all kinds of magnetic devices such as transformer, high frequency magnetic amplifier, smoothing choke.Along with the development of electronics industry, traditional single magnetic core no longer can be met the need of market completely, if multiple magnetic cores can be combined to use, just can increase core volume and make its scope of application wider, but how ensure that the interference free performance of combined magnet core is the difficult problem perplexing in the industry.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of anti-interference magnetic core that can use separately, also can be used in combination.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
A kind of combined anti-interference magnetic core, comprises two magnetic core monomers, and described magnetic core monomer comprises magnetic core body and is shaped in the magnetic post on magnetic core body; Described magnetic core body comprises: integrated base and form three sidewalls of semi-surrounding structure with base, described magnetic post be arranged on base and magnetic post and three sidewalls between all leave the space that winds the line, described magnetic post and three sidewalls are contour; On described magnetic post, be provided with accordingly the joint pin and the syndeton that connect two magnetic core monomers, after described joint pin dismounting, can be contained in syndeton.
Aforementioned magnetic post is columniform, be arranged at base marginal position and and three sidewalls between distance equate.
Aforementioned lateral wall comprises: the first side wall being parallel to each other and the second sidewall, be connected the 3rd sidewall of the first side wall and the second sidewall, the internal face of the close magnetic post of described the 3rd sidewall is arc.
Aforementioned joint pin is riveted or is buckled on the sidewall of described magnetic post, and described syndeton is to hold the groove of joint pin.
Further, in aforementioned magnetic post, form along its length a cylinder shape groove to improve interference free performance.
Usefulness of the present invention is: magnetic core of the present invention can use separately also and can be used in combination, the scope of application is wider, design ingenious, coil turn that can coiling on magnetic post is more, thereby properties of product are more remarkable, and, unique structure is given the interference free performance that product is good, effectively suppressed High-frequency Interference, research shows, groove is set along its length in magnetic post can also further improves the interference free performance of magnetic core.
Brief description of the drawings
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 numeral in figure: 1, magnetic core monomer, 2, magnetic post, 3, base, 4, the first side wall, 5, the second sidewall, 6, the 3rd sidewall, 7, joint pin, 8, syndeton, 9, cylinder shape groove.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.
Referring to Fig. 1, the combined anti-interference magnetic core of one of the present invention, comprises two magnetic core monomers 1, and specifically, each magnetic core monomer 1 includes magnetic core body and is shaped in the magnetic post 2 on magnetic core body.Wherein, magnetic core body comprises: integrated base 3 and form three sidewalls of semi-surrounding structure with base 3, magnetic post 2 be arranged on base 3 and magnetic post 2 and three sidewalls between all leave coiling space, magnetic post 2 and three sidewalls are contour.So, magnetic post 2 is arranged in a semi-surrounding structure, than the product of traditional structure, has good interference free performance.For two magnetic core monomers 1 are connected, on magnetic post 2, be provided with accordingly the joint pin 7 and the syndeton 8 that connect two magnetic core monomers 1, when combination, the joint pin 7 of first magnetic core monomer 1 coordinates with the syndeton 8 of second magnetic core monomer 1, and the joint pin 7 of second magnetic core monomer 1 and the syndeton 8 of first magnetic core monomer 1 coordinate, two semi-surrounding structures have just formed a full structure of surrounding, and anti-interference can further improve.Dexterously, after joint pin 7 dismountings, can be contained in syndeton 8, so, in the time that magnetic core monomer 1 uses separately, joint pin 7 to be pulled down and is placed in syndeton 8, the surface of magnetic post 2 is also smooth, ensures that its performance can not be affected.
Preferably, magnetic post 2 is columniform, be arranged at base 3 marginal position and and three sidewalls between distance equate.As shown in Figure 1, sidewall comprises: the first side wall 4 being parallel to each other and the second sidewall 5, be connected the 3rd sidewall 6 of the first side wall 4 and 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 space between magnetic post 2 and sidewall become large, and namely " window " increases, and coil turn that can coiling is also just more, contributes to improve the performance of product.
As a kind of concrete structure, joint pin 7 is riveted or is buckled on the sidewall of described magnetic post 2, and syndeton 8 is for holding the groove of joint pin 7.
Further, in magnetic post 2, form along its length a cylinder shape groove 9, studies have shown that, this structure can further improve the interference free performance of magnetic core, when being applied on electronic product, can significantly improve the anti-electromagnetic interference capability of electronic product, effectively suppress High-frequency Interference.It should be noted that, this cylinder shape groove 9 does not communicate with previously described syndeton 8.
More than show and described general principle of the present invention, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
