Description
Technical field
A kind of induction structure is the utility model is related to, specifically a kind of high frequency AH series inductance structures, main application
In high frequency pfc circuit, Boost circuit and inverter circuit.
Background technology
In Chinese patent literature, disclose an entitled skeleton, inductor and answer the inductor electronic installation practicality
New patent, publication number are CN205723054U, and it includes magnetic core, coil and skeleton, and the skeleton is sheathed on the magnetic core,
The coil is arranged on the skeleton, and the magnetic core includes two center pillar magnetic cores and two yokes, described two center pillar magnetic cores
It is juxtaposed between described two yokes, is arranged skeleton on each center pillar magnetic core, the coil is by flat wire along the skeleton
Coiling is formed, and the skeleton includes two limbs, and described two limbs form the hollow cylinders for housing the magnetic cores, two
The intersecting end of limb is provided with the snap-in structure to cooperate.Inductor of the present utility model is easy for installation, and reliability is high.But
It is in the patented technology, two coils are absolute construction, and each coil has two terminals, makes wiring welding procedure cumbersome,
Welding node easily aoxidizes, and influences inductance working effect.
Utility model content
The utility model provides a kind of high frequency AH series inductance structures, solves to improve coil-winding efficiency and simplify and welds
The technical problem of technique.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical scheme that：
A kind of high frequency AH series inductance structures, including two windings, it is characterised in that two windings are by same root enamel-covered wire
It is wound.
On the basis of such scheme, following improvement is also done：
Insulation board is set between the coil and yoke of the winding, two through holes, the end of center pillar magnetic core are formed on insulation board
Through hole is run through in portion.
The insulation board forms the built-in slot surrounded by annular sidewall towards the side of yoke, and yoke is buckled in built-in slot
In.
The yoke is octagon symmetrical structure.
The magnetic core is made up of iron silicon, iron sial or ferrite, and shape is rounded or oval.
The enamel-covered wire is flat type aluminium wire structure.
Compared to the prior art, beneficial effect caused by the utility model is to improve coil-winding efficiency and simplified Welder
Skill, specifically with an enamel-covered wire on two center pillar magnetic cores coiling, two windings arranged side by side are formed, between two windings
Connected by enamel-covered wire, realize the automation mechanized operation of two coil windings, reduce human cost, reduce the terminals quantity of winding,
So as to reduce pad, simplify welding procedure.
Because induced-current caused by product energization material internal is only distributed in the surface of wire, during equivalent to real work
Line causes resistance value bigger than normal, loss increase, using lenticular wire coiling, then, can according to the skin depth of different frequency sections through diminishing
Effectively reduce or remove because of round wires winding because the copper loss that kelvin effect is brought increases problem, reduce layer capacitance, improve impedance
Improve EMI effects.Flat type aluminium wire coiling is realized, reduces material cost.
Yoke is in octagon intermediate symmetry, and this structure design is ensureing effective magnetic circuit length portion cross-sectional area identical
In the case of, it is minimum using material, save material cost；Core material is low noise SFD materials.
Center pillar magnetic core can polylith be bonded together, according to different electric currents, inductance value require increase its height, be effectively increased whole
The length of magnetic path of individual product.
Brief description of the drawings
Fig. 1 is that structure of the present utility model splits reference chart.
Fig. 2 is the structural reference figure of two windings of the present utility model.
Fig. 3 is the structural reference figure of insulation board.
Reference
1 enamel-covered wire, 2 windings, 3 yokes, 4 insulation boards, 5 windings, 6 yokes, 7 center pillar magnetic cores,
8 center pillar magnetic cores, 9 through holes, 10 through holes, 11 annular sidewalls.
Embodiment
The utility model is elaborated with reference to the accompanying drawings and examples.
Such as Fig. 1, two windings (winding 2 and winding 5) form the primary structure of inductance, are above two windings side by side
Yoke 3, lower section are yokes 6, and two yokes are separately fixed at the end of the center pillar magnetic core of winding.
Such as Fig. 2, center pillar magnetic core 8 and center pillar magnetic core 7 are wound with same root enamel-covered wire 1, form winding 2 and winding 5.
In order to prevent the coil that is coiled into of yoke abrasion enamel-covered wire, insulation board is placed between yoke and coil, with installed in
Exemplified by the insulation board 4 of top, reference picture 3, through hole 9 and through hole 10, two through holes are set to be just met for center pillar magnetic core on insulation board 4
Pass through, with reference to Fig. 1, such benefit is can either to meet that yoke 3 and center pillar magnetic core combine, and can by yoke 3 and inductance loop seclusion,
Avoid wearing enamel-covered wire, and turned on after avoiding enamel-covered wire breakage with yoke 3, influence inductance normal work.
Such as Fig. 1 and Fig. 3, annular sidewall 11, such annular sidewall are further formed on side of the insulation board towards yoke
11 surround built-in slot, and yoke is embedded in built-in slot, and the effect of built-in slot is protection and fixed yoke.
