Description
Technical field
The utility model relates to a kind of magnetic core, relates in particular to a kind of magnetic core that is mainly used in coil class inductance components such as electric ballast, electronic transformer.
Background technology
Traditional coil class inductance component generally cooperates bobbin (skeleton) to form around last enamelled wire by EE type magnetic core or EI type magnetic core.In order to prevent that the magnetic saturation phenomenon from taking place, need in magnetic circuit, be provided with air gap, air gap places the center pillar of magnetic core usually, near air gap coil is because there is very big leakage field (leakage inductance) phenomenon in the characteristic of magnetic circuit, and air-gap permeance is extremely low, therefore near the coil the air gap can't be participated in power conversion, can't have no progeny in switch control valve pass gives off energy, and magnetic field is resetted, and can only play filling effect.Because have the gap between bobbin and the magnetic core, increased the winding length of coil again.For above-mentioned reasons, cause the increase of device self copper resistance and copper loss, the temperature of device is raise, waste electric energy and copper material reduce useful life.
Summary of the invention
The purpose of this utility model provides a kind ofly can significantly save copper material and electric energy, reduces the U font magnet and the T font magnet combination magnetic core of temperature rise.
The utility model is provided with U font magnet and T font magnet, and U font magnet is provided with straight-arm and is positioned at 2 folding arms of straight-arm both sides; T font magnet is provided with perpendicular arm and is positioned at the transverse arm of perpendicular arm upper end, the perpendicular arm of T font magnet is located between 2 folding arms of U font magnet, be provided with air gap between the inner surface of the straight-arm of the lower surface of the perpendicular arm of T font magnet and U font magnet, be provided with air gap between the two ends of 2 folding arms of the two ends of the transverse arm of T font magnet and U font magnet.
The straight-arm of U font magnet and the cross section of folding arm can be square, rectangle, circle or ellipse etc.
The perpendicular arm of T font magnet and the cross section of transverse arm can be square, rectangle, circle or ellipse etc.
Can be provided with air gap at the perpendicular arm of T font magnet and the intersection of transverse arm.
The end face of the end face of the folding arm of U font magnet and T font magnet can be perpendicular end surface or angled end-face.
The width of each air gap can be 0.1～4.0mm,
With the magnetic core of traditional single channel air gap relatively because the utility model is provided with multichannel air gap (three road or four road air gaps), changed traditional single channel gap structure, satisfying under the instructions for use such as power, traditional single channel air gap needs bigger size; And the utility model can reduce the size of each road air gap greatly, can significantly reduce leakage field (leakage inductance) phenomenon, can effectively overcome the shortcoming of traditional magnetic core.With the magnetic core of traditional single channel air gap relatively handle owing to can carry out surface withstand voltage the utility model, coil can be directly on magnetic core, save bobbin, can save copper material greatly, reduced resistance and copper loss and electric energy, and can make magnet cooling, the useful life of improving product.
