Modular magnetic core inductance, including magnetic core I, magnetic core II and coil, magnetic core II is two cylinders that the shape is the same, magnetic core I includes two parts, is located II both ends of magnetic core respectively, is connected with II cooperations of magnetic core to form the ring -type, coil winding is on magnetic core II, for flat enamel insulated aluminum wire circle. The utility model discloses a split combined type magnetic core makes coil winding efficiency improve by a wide margin, changes the copper line for the aluminum wire simultaneously, reduces material cost, and the aluminum wire is flattening the back use, has improved window utilization ratio and heat -sinking capability, has reduced electromagnetic interference.
Description
Technical field
This utility model relates to a kind of Combined type magnetic core inductance, belongs to power supply electromagnetic element technical field.
Background technology
Inducer, its Main Function is that AC signal is carried out Isolation, the logical direct current of namely resistance exchange, the logical low frequency of resistance high frequency. For power supply product, the outputting inductance after secondary commutation can reach the purpose filtering with suppressing to exchange ripple, and therefore, inducer is indispensable element in power supply product. But, current power supply inductance many employings toroidal core coiling circular copper wire realizes, and needs wire to penetrate and pass toroidal core during ring-shaped magnetic core coiling, and efficiency is very low. Further, because of ring-type special construction, coiling can only be suitable for the copper cash that bending hot strength is higher, causes that product material cost and manufacturing cost are all very high.
Utility model content
The purpose of this utility model is in that, overcome the drawbacks described above of current power supply inductance, a kind of Combined type magnetic core inductance is proposed, and in conjunction with the flat enamel-insulated-aluminium coil that the method described in the patent CN103117169B " transformator or reactor enamel-covered wire winding manufacture Apparatus and method for " of early stage application is rolled into, obtain a kind of novel magnetic core inductance, improving production efficiency, concrete technical scheme is:
Combined type magnetic core inductance, including magnetic core I, magnetic core II and coil, magnetic core II is two cylinders that shape is identical; Magnetic core I includes two parts, lays respectively at magnetic core II two ends, is connected formation ring-type with magnetic core II; Coil winding is on magnetic core II, for flat enamel-insulated-aluminium coil.
Further, the cross sectional shape of described flat enamel insulated aluminium wire includes the irregular shape such as rectangle, ellipse, in order to after coil winding completes, sectional area with under number of turns the same terms compared with enamel-cover round wires, overall can reduce coil height, and then product cost can be reduced.
Further, described magnetic core I and magnetic core II can design different shapes according to optimization scheme, such as cylinder or cuboid etc.
Further, described magnetic core I and magnetic core II are high permeability material, such as FERRITE CORE or amorphous magnetic core.
Further, Combined type magnetic core inductance also includes shell and base. Shell primarily serves insulating effect; Base is played a supporting role, and base has false pin make high-frequency inductor be connected in circuit.
This utility model adopts separate assembling magnetic core, and magnetic core is made up of a few part regular shapes, and wire can first use during manufacture mould and the fast automatic coiling of machine, then coil is inserted in magnetic core carries out automatic assembling, greatly reduces manufacturing cost. On the other hand, because the change of wire winding, it is possible to use than copper cash, the aluminum steel of cheap 50% price carries out automatic winding, and under the premise that performance is constant, material cost declines to a great extent.
This utility model has the advantages that
1) coil winding efficiency is greatly improved, and can reach about original 10 times, and integral production efficiency improves about 5 times;
2) being replaced by aluminum steel by copper cash, material cost declines 30%;
3) aluminum steel uses after becoming compressed, improves window utilization rate and heat-sinking capability, reduces electromagnetic interference.
