Description
Technical field
The utility model relates to a kind of magnetic core, especially relates 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 E1 type magnetic core.In order to prevent that the magnetic saturation phenomenon from taking place, need in magnetic circuit, be provided with the air air gap, the air air gap places the center pillar of magnetic core usually, near the air air gap coil is because the characteristic of magnetic circuit, have very big leakage field (leakage inductance) phenomenon, the air air-gap permeance is extremely low, so near the coil the air air gap can't be participated in power conversion, can't have no progeny to give off energy in switch control valve pass resets magnetic field, 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 I-shaped magnet and the I font magnet combination magnetic core of temperature rise.
The utility model is provided with I-shaped magnet and 2 I font magnets; I-shaped magnet is provided with perpendicular arm and is positioned at 2 transverse arms at perpendicular arm two ends, and 2 I font magnets are located at the both sides of the perpendicular arm of I-shaped magnet, are equipped with the air air gap between the two ends of the two ends of 2 I font magnets and 2 transverse arms of I-shaped magnet.
Lower cross arm length in 2 transverse arms of I-shaped magnet is greater than Top Crossbeam length, and described air air gap is located between the lower surface and lower cross arm two ends of 2 I font magnets, and is located between 2 I font magnet upper end medial surfaces and the Top Crossbeam both ends of the surface.
The length of 2 transverse arms of I-shaped magnet is identical, and described air air gap is located between the end face at the two ends medial surface of 2 I font magnets and transverse arm two ends.
The length of 2 transverse arms of I-shaped magnet is identical, and described air air gap is located between the medial surface at the two ends end face of 2 I font magnets and 2 transverse arm two ends.
The perpendicular arm of I-shaped magnet and the cross section of transverse arm can be square, rectangle, circle or ellipse etc.
The cross section of I font magnet can be square, rectangle, circle or ellipse etc.
The width of described air air gap can be 0.3～2.5mm.
With the magnetic core of traditional single channel air air gap relatively because the utility model is provided with multichannel (4 tunnel) air air gap, changed traditional single channel air gap structure, satisfying under the instructions for use such as power the bigger size of needs of traditional single channel air air gap; And the utility model can reduce the size of 4 road air air gaps greatly, can significantly reduce leakage field (leakage inductance) phenomenon, can effectively overcome the shortcoming of conventional cores.With the magnetic core of traditional single channel air air gap relatively handle owing to can carry out surface withstand voltage the utility model, coil can be directly on magnetic core, saved bobbin, can save copper material greatly, reduce resistance and copper loss and electric energy, and can make device cooling, the useful life of improving product.
