Have a side magnetic part, be the arcwall face being adapted with coil shape on the inside of the side magnetic part, between the arcwall face and center magnetic pole between
Coil accommodating chamber is formed every setting.
As an improvement, the upper magnetic part is fan-shaped upper magnetic part.
As an improvement, the coil is the spiral coil of flat wire coiling, the coil both ends stretching magnetic core is simultaneously downward
Exit is extended to form, the exit end is equipped with connecting terminal.
As an improvement, the coil turns to several layers from the bottom to top, gap is separated by form air duct between every layer of coil.
As an improvement, the connecting terminal is located at same horizontal line.
As an improvement, the coil is made of copper wire.
The present invention has the advantage that：(1) magnetic core is divided into upper layer and lower layer in the present invention, so that magnetic core carries out out breath, increases
Big product magnetic permeability, can prevent product to be saturated.
(2) coil in the present invention is spiral winding made of flat wire made of copper wire and coiling, and dependence is planar junction
Structure, it is convenient to radiate than cylinder enameled wire, and air duct in addition can be formed between coil, it is easier to and it radiates, makes it that can cross more high current,
And this coil can be produced with automatic machinery, less manpower, yield is high.
(3) the configuration of the present invention is simple, production is simple, and this product can effectively be such that product electric current increases, and yield increases, and meets
The demand of electronic equipment.
