Abstract
The utility model discloses a combined magnetic core of a C-shaped magnet and an I-shaped magnet, which relates to a magnetic core, in particular to a magnetic core mainly applied to coil inductance components, such as electronic ballasts and electronic transformers. The utility model provides a combined magnetic core of a C-shaped magnet and an I-shaped magnet which can obviously save copper products and electric energy and reduce temperature rise. The magnetic core comprises an C-shaped magnet and an I-shaped magnet; the I-shaped magnet is arranged inside the C-shaped magnet, an air gap is arranged between the end surface at one end of the I-shaped magnet and the inner side surface at the middle part of the C-shaped magnet, and air gaps is arranged between the both side surfaces at the other end of the I-shaped magnet and the end surfaces at the both openings of the C-shaped magnet.
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 1 C font magnet and 1 I font magnet; I font magnet is positioned at C font magnet, is provided with air gap between an end end face of I font magnet and the middle part medial surface of C font magnet, is provided with air gap between two open ends of the other end two sides of I font magnet and C font magnet.
C font magnet can be the C font magnet of integral type; The C font magnet box-like magnet of C glyph group that at least two magnets butt joints forms of also can serving as reasons, described butt joint can be adopted bonding.
The width of air gap can be 0.1～4.0mm.
The cross section of C 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 (three 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 three 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.
