Description
Technical field
The utility model relates to inductance component, relates in particular to the inductance component that a kind of UUI of employing type magnetic core is made, and can be widely used in the electronic circuit of various electronic apparatuss.
Background technology
Traditional coil class inductance component generally cooperates bobbin to form around last enamelled wire by EE type magnetic core or EI type magnetic core.For the anti-magnetic saturation phenomenon that goes up takes place, need be provided with air gap in magnetic circuit, air gap places the center pillar of magnetic core usually, has dispersing flux near air gap, dispersing flux makes near the coiler part the air gap lose the transformation of " electricity-magnetic ", and near the coil sections the air gap place 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 the increase of device self copper resistance and copper loss, the power consumption of device is raise, waste electric energy and copper material, the useful life of reducing inductance component.
Summary of the invention
The purpose of this utility model provides a kind of inductance component that can significantly save copper material, improve quality factor (being the Q value).
The technical solution of the utility model is achieved in that
A kind of inductance component is characterized in that, comprises an I font magnet, two U font magnets, coil and coil baffle plates; Described U font magnet is provided with straight-arm and is positioned at two folding arms at straight-arm two ends; Described coil baffle plate is provided with the magnet slot; The two ends of I font magnet are inserted respectively in the magnet slot of two coil plate washers, coil twines and to be arranged on two I font magnets between the coil plate washer, the export-oriented end face of two U font side column magnet folding arms is affixed to I font magnet side faces at both ends respectively forms a day font closed magnetic loop; On I font magnet, be provided with insulating barrier, between the export-oriented end face of I font magnet side faces at both ends and U font magnet, be provided with the air gap medium.
The beneficial effects of the utility model are: compare with the inductance component of traditional employing EE type magnetic core, owing to employing four magnetic air gaps of the present utility model, changed single magnetic air gap structure of traditional devices, make the magnetic circuit magnetic pressure be evenly distributed, can significantly reduce dispersing flux, improve magnetic circuit; Magnetic air gap is arranged on I font magnet and U font magnet joint, and the dispersing flux that makes the magnetic air gap place enter coil reduces; Dispersing flux reduces to make its influence to coil to reduce, and the induction factor of magnetic core increases, and makes coil turn reduce and the saving copper material.The insulating barrier of I font magnet is thinner, and the coil of innermost layer is close to I font magnet, has reduced the diameter of coil and can further save copper material.
Below in conjunction with drawings and Examples the utility model is described in detail.
