Abstract
The utility model discloses a combined magnetic core of an E-shaped magnetic body and an I-shaped magnetic body, comprising an I-shaped magnetic body, two sides of the I-shaped magnetic body are provided with E-shaped magnetic bodies, the E-shaped magnetic body is provided with a straight arm and bending arms arranged at two ends of the straight arm, a middle arm is arranged between the two bending arms, the end surfaces of the two bending arms of the two E-shaped magnetic bodies and the middle arm are opposite, and an air gap is arranged between the two E-shaped magnetic bodies and the I-shaped magnetic body; an air gap structure of a traditional coil inductor component is changed, so as to remarkably reduce the phenomenon of flux leakage, reduce resistance, copper loss and electrical energy, reduce the temperature of the magnetic body and improve the service life of products.
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
At present, coil class inductance component generally cooperates bobbin to form around last enamelled wire by EE 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 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.Thereby, 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
In order to overcome the deficiencies in the prior art, the purpose of this utility model provides a kind ofly can significantly save copper material and electric energy, reduces the E font magnet and the I font magnet combination magnetic core of temperature rise.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of E font magnet and I font magnet combination magnetic core, it comprises I font magnet, I font magnet both sides are provided with E font magnet, E font magnet is provided with straight-arm and is positioned at the folding arm at straight-arm two ends, be provided with intermediate arm between two folding arms, two folding arms of two E font magnets and the end face of intermediate arm are relative, are provided with air gap between two E font magnets and the I font magnet;
As improvement of the technical scheme, the middle brachium of two folding arm length of described E font magnet;
As further improvement in the technical proposal, the cross section of described E font magnet and I font magnet is square, rectangle, circle or oval; The width of described air gap is 0.1～4mm.
The beneficial effects of the utility model are: the utility model has changed the gap structure of conventional coil class inductance component, can significantly reduce the leakage field phenomenon, reduces resistance and copper loss and electric energy, and can make magnet cooling, the useful life of improving product.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Embodiment
With reference to Fig. 1, a kind of E font magnet and I font magnet combination magnetic core, it comprises I font magnet 1, I font magnet 1 both sides are provided with E font magnet 2, E font magnet 2 is provided with straight-arm 21 and is positioned at the folding arm 22 at straight-arm 21 two ends, the end face that is provided with two folding arms 22 of intermediate arm 23, two E font magnets 2 and intermediate arm 23 between two folding arms 22 is relative, is provided with air gap 3 between two E font magnets 2 and the I font magnet 1.
Two folding arms, 22 length of the E font magnet 2 that this product uses are long than intermediate arm 23; In addition, the cross section of described E font magnet 2 and I font magnet 1 is square, rectangle, circle or oval, and air gap 3 width between two E font magnets and the I font magnet are 0.1～4mm; Certainly according to actual needs; the shape of cross section of E font magnet 2 and I font magnet 1 and the width dimensions of air gap 3 can design and produce according to actual instructions for use; in a word so long as, all belong to protection range of the present utility model with essentially identical means realization the purpose of this utility model.
The utility model has changed the gap structure of conventional coil class inductance component, can significantly reduce the leakage field phenomenon, reduces resistance and copper loss and electric energy, and can make magnet cooling, the useful life of improving product.
