Description
Technical field
The utility model relates to magnetic core technical field more particularly to a kind of novel ferrite core structures.
Background technique
Currently, it minimizes and inclined graduation is the development main trend of entire electronic product, as main magnetic group therein
Part-power transformer is also necessarily required to realize inclined graduation, and EFD, DS and EER type magnetic core are inclined flat pattern power transformers at present
The main core type used.
DS and EER type matches with vertical-type skeleton, and winding height is limited, is unable to satisfy the design of electronic transformer Multiple coil
It is required that and EFD type matches with horizontal-type skeleton, can satisfy the requirement of electronic transformer Multiple coil design, but identical
Within the scope of plane space, useful flux area is smaller, influences the power output of electronic transformer, to improve power output energy
Power and adaptation Multiple coil requirement, need to modify to the structure of magnetic core.
Utility model content
The purpose of the utility model is to provide a kind of novel ferrite core structures, it is increased on original core structure
New connection structure becomes smaller in size whole in the case where guaranteeing that the sum of magnetic flux area is constant so as to realize,
To realize the purpose of miniaturization, keep its application range in use wider, the stability in use process more may be used
It leans on.
The technical solution of the utility model is as follows:
The upper end of a kind of novel ferrite core structure, including rectangle magnetic core bottom plate, the magnetic core bottom plate is located at left and right
The center in direction be equipped with a rectangle magnetic core stem, the upper end of the magnetic core bottom plate be respectively arranged on the left side and the right side one at
The rectangle side leg structure of type, the end face outside of the side leg structure and the end face outside of the magnetic core bottom plate are parallel to each other, institute
The front in the front and the magnetic core bottom plate of stating magnetic core stem is in the same plane, it is characterised in that: the two side legs in left and right
Structure is equipped with integrally formed arc-shaped side leg circular arc boss, institute by the position of rear end close to the end face of magnetic core bottom plate side
State the straight line that cylindrical center's axis of side leg circular arc boss intersects between the magnetic core bottom plate left and right directions center and front
On, the upper surface in leg circular arc boss and it is described while leg structure upper surface in the same plane, the side leg circular arc is convex
The back end surface of the back end surface of platform and the side leg structure in the same plane, the side leg circular arc boss and the magnetic core bottom
The position of the back end surface connection of plate is equipped with an arc-shaped transition and connects arc structure.
Further, the width of the magnetic core stem is less than the width of the magnetic core bottom plate.
The utility model has the beneficial effects that
The utility model increases new connection structure on original core structure, is guaranteeing magnetic flux face so as to realize
Whole is become smaller in size in the case that the sum of product is constant, to realize the purpose of miniaturization, makes it in use process
In application range it is wider, the stability in use process is more reliable.

Specific embodiment
As shown in Figures 1 to 4, a kind of novel ferrite core structure, including rectangle magnetic core bottom plate 1, the magnetic core bottom
The center that the upper end of plate 1 is located at left and right directions is equipped with a rectangle magnetic core stem 3, and the upper end of the magnetic core bottom plate 1 is left
Right two sides are respectively equipped with integrally formed rectangle side leg structure 2, the end face outside of the side leg structure 2 and the magnetic core bottom plate
1 end face outside is parallel to each other, and the front of the positive and magnetic core bottom plate 1 of the magnetic core stem 3 is in the same plane, special
Sign is: left and right two side leg structures 2 close to 1 side of magnetic core bottom plate end face by rear end position be equipped with one at
The arc-shaped side leg circular arc boss 4 of type, cylindrical center's axis of the side leg circular arc boss 4 are 1 left and right directions of magnetic core bottom plate
On the straight line intersected between center and front, the upper surface in leg circular arc boss 4 and it is described while leg structure 2 upper end
Face in the same plane, the back end surface in leg circular arc boss 4 and it is described while leg structure 2 back end surface in same plane
On, the position that the side leg circular arc boss 4 is connect with the back end surface of the magnetic core bottom plate 1 is equipped with an arc-shaped transition connection
Arc structure 5.According to Analysis of Magnetic Circuit, the sum of the magnetic flux area of both sides leg should be equal to the magnetic flux area of stem, and EFD magnetic core leads to
In normal structure (as shown in figure 1 shown in original structure), since skeleton window matched with magnetic core is certain, therefore the B ruler close to stem side
It is very little certain, to guarantee side leg area, then A relatively large sized (side leg area A=D* (A-B)).It is taken up too much space in this way.
In new construction, side leg structure is made certain improvements, as shown in the new construction figure in the following figure,
The starting point of circular arc in the leg of side are as follows: the magnetic core edge C size away from stem side, the area of side leg can approximate calculation be D*
(A-B)+(B-G) * (D-C) will reach same side leg area, then A size can reduce a scale in this way compared with original structure
It is very little, and then save the space occupied in electronic transformer assist side.This kind of magnetic core new construction is named as ECD type.
Preferably, the width of the magnetic core stem 1 is less than the width of magnetic core stem 3 described in the width of the magnetic core bottom plate 2
Degree is less than the width of the magnetic core bottom plate 1, is more convenient when carrying out coiling, function is more stable when in use, and effect is more preferable.
The above is preferred embodiments of the present invention, it is noted that for the ordinary skill of the art
For personnel, under the premise of not departing from principle described in the utility model, it can also make several improvements or replace, these improvement
Or replacement also should be regarded as the protection scope of the utility model.
