Abstract
The utility model relates to a UUI type integrated inductor which comprises a UUI type magnetic return path magnetic core, air gap media and coils. The UUI type magnetic return path magnetic core comprises two I-shaped magnets and two E-shaped magnets, each E-shaped magnet is provided with a straight arm, two ends of the straight arm are respectively provided with an end folded arm, a middle folded arm is arranged in the middle of the straight arm, and the middle folded arm and the end folded arms are placed on the same side of the straight arm. The two I-shaped magnets are respectively provided with a coil in wound mode, the two coils are connected with each other in series, and the outward end faces of the two E-shaped magnets are correspondingly attached together to form a closed magnetic loop circuit. Magnetic circuit air gaps are arranged between the end faces of the I-shaped magnets and the inner side faces of the straight arms of the E-shaped magnets, and the air gap media are arranged inside the air gaps. The UUI type integrated inductor has the advantages of saving copper material, reducing power consumption of components, saving electric energy and prolonging service life of products, saving magnetic material, and being capable of being used for an electrical appliance which is limited by an installation space.
Description
Technical field
The utility model relates to inductor, relates in particular to UUI type inductor, can be widely used in the electronic circuit of various electronic apparatuss.
Background technology
Traditional inductance component generally cooperates bobbin to form around last enamelled wire by EE type magnetic core or EI type magnetic core.For preventing that the magnetic saturation phenomenon from taking place, common way is to adopt the method for grinding the magnetic core center pillar that magnetic air gap is set, and air gap is in the line bag center of inductor.Because near magnetic air gap, exist dispersing flux, dispersing flux to make near the coiler part of air gap lose the transformation of " electricity-magnetic ", the AL value of magnetic core reduces, near the coil sections the magnetic air gap only plays filling effect.The big more dispersing flux of air gap amount is just big more, and the coil of invalid filling is also just many more, and the magnetic line of force vertically passes the line bag simultaneously, causes the certain power loss.Above-mentioned reason causes device self copper resistance and copper loss to increase, and the power consumption of device is raise, waste electric energy and copper material, the useful life of reducing inductance component.On the circuit of some electronic apparatuss, need two or more inductor series connection to use, the way in past is to connect with a plurality of independently inductors, the result had both increased inductance area occupied in circuit, had increased the loss of production cost and circuit again.
Summary of the invention
The purpose of the utility model provides a kind of UUI type integrated inductor that can significantly practice thrift copper material and improve quality factor.
The technical scheme of the utility model is achieved in that
UUI type integrated inductor is characterized in that, comprises UUI type magnetic loop magnetic core array, air gap medium and coil; Said UUI type magnetic loop magnetic core array comprises two I font magnets and two E font magnets; Said E font magnet is provided with a straight-arm, is respectively equipped with the end folding arm at the straight-arm two ends, on the straight-arm centre position, is provided with middle folding arm; On two I font magnets, twine two coils that are serially connected are set; The inboard of two E font magnet straight-arms is affixed to the end face of two I font magnets respectively; Make I font magnet be arranged in the centre position of E font magnet end folding arm and folding arm, make the export-oriented end face of the two E font magnet folding arms formation closed magnetic loop that fits together accordingly simultaneously; Between the medial surface of the end face of I font magnet and E font magnet straight-arm, be provided with magnetic air gap, in magnetic air gap, be provided with the air gap medium.
The beneficial effect of the utility model is:
1, the utility model is compared with the inductance component of Traditional use EE type or EI type magnetic core, because the utility model has changed single magnetic air gap structure of traditional devices, has adopted more reasonably magnetic structure of magnetic air gap position; Magnetic pressure is evenly distributed; Dispersing flux reduces, and dispersing flux reduces the influence of coil, and the induction factor of magnetic core increases; Thereby the minimizing coil turn has been saved copper material.
2, the utility model inductor air gap has reduced the influence of dispersing flux effectively away from the line bag, has reduced the power loss of device, not only saves energy but also prolong useful life of product.
3, the utility model inductor can replace the operating position of 2～3 traditional inductor series connection, has not only saved the magnetic material but also can on installing space receives the electrical equipment of certain limitation, use.
Below in conjunction with accompanying drawing and embodiment the utility model is described in detail.
