Abstract
Disclosed is a combined magnet core which is formed by a L-shaped magnet body and a I-shaped magnet body, which relates to a magnet core, in particular to a magnet core for the coil inductance components such as an electronic ballast, an electronic transformer and the like, and provides the combined magnet core which is formed by the L-shaped magnet body and the I-shaped magnet body and can obviously save the copper material and power energy and reduce the temperature rise. Two L-shaped magnet bodies and an I-shaped magnet body are arranged on the combined magnet core; Two L-shaped magnet bodies can form a magnet body which is shaped like a Chinese character kou, the I-shaped magnet body is positioned in the magnet body which is shaped like a Chinese character kou, air clearance is arranged between two ends of two L-shaped magnet bodies, and the air clearance is also arranged between two end surfaces of the I-shaped magnet body and the inside surfaces of two L-shaped magnet bodies.
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 2 L font magnets and 1 I font magnet; 2 L font magnets are formed the square shape magnet, and I font magnet is positioned at the square shape magnet of being made up of 2 L font magnets, is provided with air gap between the two ends of 2 L font magnets, is provided with air gap between the medial surface of the both ends of the surface of I font magnet and 2 L font magnets.
2 end faces of L font magnet can be perpendicular end surface or angled end-face.
The width of air gap can be 0.1～4.0mm.
Between the end face of an end that air gap between 2 L font magnet two ends can 1 L font magnet located therein and the medial surface of other 1 L font magnet one end, or be located between 2 end faces at two ends of 2 L font magnets.
The cross section of L font magnet and I font magnet can be geometries such as square, rectangle, circle or ellipse.
With the magnetic core of traditional single channel air gap relatively because the utility model is provided with multichannel air gap (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 four road air gaps 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.
