Description
Technical field
The utility model relates to magnetic elements technical field, more particularly relates to a kind of novel magnetic elements core structure.
Background technology
Magnetic element is made up of winding and magnetic core usually, and it is the essential power electronic device of energy storage, power conversion and electrical isolation, mainly comprises transformer and the large class of inductor two.In nearly all power circuit, all be unable to do without magnetic elements, magnetic elements is one of most important part of power electronic technology.Common magnetic elements, if PFC inducer is toroidal core, adopt annular powder core magnet ring coiling, because the coiling of ring-shaped P FC inductance cannot adopt machine coiling substantially, by hand wound, labour intensity is large and quality is unstable, discreteness is large, consuming time more, the features such as production efficiency is low, are widely used in traditional inductor product.But along with the pay rise of workman, the advantage of magnet ring inductance is more and more not obvious, and the disappearance of Chinese labour force bonus, coiling transformer or inductance, need higher cost increase.
Utility model content
The technical problem that the utility model solves is the novel magnetic elements core structure providing a kind of cost low.
For solving the problems of the technologies described above, the technical scheme adopted is: a kind of novel magnetic elements core structure, comprise the closed magnetic core of I type magnetic stripe composition, and winding is tied with on described magnetic core, described magnetic core is " mouth " type structure, described winding comprises the first winding and the second winding, and the first winding and the second winding symmetry are wound on the peripheral magnetic stripe of " mouth " type structured core; Described magnetic core is " day " type structure, and " day " type structured core comprises peripheral magnetic stripe and center pillar magnetic stripe, and described winding is wound on the center pillar magnetic stripe of " day " type structured core.
Further, described winding is enamel covered wire winding or Copper Foil wire-wound group.
The beneficial effects of the utility model are: the utility model adopts I type magnetic stripe to be assembled into " mouth ", " day " type magnetic core, compared with toroidal core, tool has the following advantages: because the I bar magnetic stripe identical by shape forms difform magnetic core, air gap can also be regulated to change inductance value and DC stacked inductance simultaneously, thus considerably increase magnetic core consumption of the same race, be conducive to magnetic core to produce in enormous quantities, and core shapes is simple and easy to automated production, thus reduces costs; Effective shortening length of magnetic path, therefore being conducive to improving electric inductance power, under the condition that power is identical, inductance value is also under same case, inductance volume is less, effectively save space; Due to difform magnetic core can be formed by I type magnetic stripe, client's different capacity, different type of machines is facilitated to adopt, magnetic core number of molds is reduced due to magnetic core normalization, adjust different induction value by adjustment junction air gap, powder can keep normalization to carry out the inductance coefficent demand of satisfied different AL value.
Accompanying drawing explanation
Fig. 1 is a kind of example structure figure of the utility model.
Fig. 2 is the another kind of example structure figure of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail:
A novel magnetic elements core structure, comprises the closed magnetic core of I type magnetic stripe composition, and be tied with winding on described magnetic core; Type structure that magnetic core comprises " mouth " and " day " type structure.
As shown in Figure 1, the magnetic core in the present embodiment is " day " type structure, the closed magnetic core be made up of I type magnetic stripe 10, and " day " type structured core comprises peripheral magnetic stripe 31 and center pillar magnetic stripe 32, and winding 20 is wound on the center pillar magnetic stripe 32 of " day " type structured core.Winding 20 is enamel covered wire winding or Copper Foil wire-wound group.Peripheral magnetic stripe 31 scribbles glue I type magnetic stripe 10 is combined, I type magnetic stripe 10 is the powder core magnetic stripes suppressed by iron sial powder, iron silica flour material, iron nickel powder material, iron nickel molybdenum, iron silicon boron etc., consist of center pillar unshakable in one's determination and peripheral two parts, in iron core, column sleeve has winding 20, periphery is used for closed magnetic circuit, peripheral magnetic stripe quantity used is one, and center pillar magnetic stripe quantity used is two.The magnetic core of the present embodiment also can be the magnetic core that nickel-zinc ferrite or MnZn ferrite material are made.Enamel covered wire or Copper Foil wire-wound group composition inductor winding, enamel covered wire, Copper Foil are processed into line bag through equipment, can adopt automated production, are conducive to raising the efficiency, and reduce workman.
As shown in Figure 2, magnetic core in the present embodiment is " mouth " type structure, winding comprises the first winding 21 and the second winding 22, first winding 21 and the second winding 22 symmetry are wound on the peripheral magnetic stripe 31 of " mouth " type structured core, both sides are used for closed magnetic circuit in addition, and peripheral magnetic stripe quantity used is two.Winding material used is enamel covered wire or Copper Foil line.The material that I type magnetic stripe 10 adopts is the powder core magnetic stripe of the compactings such as iron sial powder, iron silica flour material, iron nickel powder material, iron nickel molybdenum, iron silicon boron; The material of magnetic core also can be nickel-zinc ferrite or manganese-zinc ferrite in addition.
Magnetic elements core structure of the present utility model is mainly to substitute the scheme of the alloy magnetic powder core magnet ring of existing routine, easy to implement, the automation of coil winding technique can be conducive to, magnetic core is easy to assembly, magnetic core specification is single, be beneficial to the features such as volume procurement highly versatile, this core material adopts alloy powder core (iron sial, iron silicon, iron nickel, Deng material), make I type magnetic stripe to combine, in simple and magnetic core, air gap is evenly distributed, also outside air gap can be regulated when assembling magnetic core, to reach the adjustment of inductance, this structural design is at magnetic core consumption, material is single, coil winding adopts the aspects such as automation mechanized operation to have larger cost advantage.
Because the I bar magnetic stripe identical by shape forms difform magnetic core, air gap can also be regulated to change inductance value and DC stacked inductance simultaneously, thus considerably increase magnetic core consumption of the same race, be conducive to magnetic core and produce in enormous quantities, and core shapes is simple and easy to automated production, thus reduce costs; Effective shortening length of magnetic path, therefore being conducive to improving electric inductance power, under the condition that power is identical, inductance value is also under same case, inductance volume is less, effectively save space; Due to difform magnetic core can be formed by I type magnetic core, client's different capacity, different type of machines is facilitated to adopt, magnetic core number of molds is reduced due to magnetic core normalization, adjust different induction value by adjustment junction air gap, powder can keep normalization to carry out the inductance coefficent demand of satisfied different AL value.
The foregoing is only preferred implementation of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
