Abstract
The invention discloses a kind of magnetic core of transformer, include the core body of rectangular flat shape, the core body is provided with center pillar in mid-length position, the core body is arranged with side column in the both sides of center pillar, the both ends of the surface of the center pillar are concordant with the width two sides of core body, the lateral surface of the side column is concordant with the length two sides of core body, and the both ends of the surface of the side column and the width two sides of core body are provided with spacing distance.The present invention is different from the prior art, the center pillar both ends technical scheme simultaneously concordant with core body width two sides with side column both ends, side column width is constant, widen center pillar and core body simultaneously, make the both ends of the surface of center pillar concordant with the width two sides of core body, therefore, the sectional area of magnetic core can be increased, and transformer miniaturization is not interfered with, it may apply to bigger power section.
Description
Technical field
The present invention relates to miniature transformer, more particularly to magnetic core of transformer.
Background technology
At present, there are higher requirement, especially magnetic core in the field such as TV, illumination to ultra-thin, miniaturization transformer, adapts to become
While depressor minimizes, core cross section product is caused to diminish, space availability ratio is relatively low, can not be applied to bigger power section.
The content of the invention
The technical problems to be solved by the invention are just to provide a kind of magnetic core of transformer, while frivolous miniaturization, increase
The sectional area of magnetic core, to be applied to bigger power section..
In order to solve the above technical problems, the present invention adopts the following technical scheme that：A kind of magnetic core of transformer, including rectangular flat
The core body of shape, the core body are provided with center pillar in mid-length position, and the core body is symmetrical in the both sides of center pillar
Provided with side column, the both ends of the surface of the center pillar are concordant with the width two sides of core body, lateral surface and the magnetic core sheet of the side column
The length side of body is concordant, and the both ends of the surface of the side column and the width two sides of core body are provided with spacing distance.
Preferably, the center pillar is rectangular cylinder and two sides are provided with circular arc concave inward structure.
Preferably, the side column is elliptic cylindrical.
Preferably, the corner of the core body is provided with arc transition structure.
The present invention is different from the prior art, and center pillar both ends are simultaneously concordant with core body width two sides with side column both ends
Technical scheme, side column width is constant, while widens center pillar and core body, makes the both ends of the surface of center pillar and the width of core body
Two sides are concordant, and the both ends of the surface of side column and the width two sides of core body form spacing distance.Therefore, magnetic core can be increased
Sectional area, and transformer miniaturization is not interfered with, it may apply to bigger power section.
Brief description of the drawings
The invention will be further described with reference to the accompanying drawings and detailed description：
Fig. 1 is the structural representation of the present invention.
Embodiment
The technical scheme of the embodiment of the present invention is explained and illustrated with reference to the accompanying drawing of the embodiment of the present invention, but under
It is only the preferred embodiments of the present invention to state embodiment, and not all.Based on the embodiment in embodiment, those skilled in the art
Other embodiment is obtained on the premise of creative work is not made, belongs to protection scope of the present invention.
As shown in figure 1, a kind of magnetic core of transformer, includes the core body 10 of rectangular flat shape, the core body is in length
Degree centre position is provided with center pillar 11, and the core body is arranged with side column 12, the both ends of the surface of the center pillar in the both sides of center pillar
Concordant with the width two sides of core body, the lateral surface of the side column is concordant with the length side of core body, the side column
Both ends of the surface and the width two sides of core body be provided with spacing distance.Compared with prior art, side column width is constant, together
Shi Jiakuan center pillars and core body, make full use of space, are filled with magnetic core, increase core cross section product, may apply to bigger
Power section.
Wherein, the center pillar 11 is rectangular cylinder and two sides are provided with circular arc concave inward structure 111.Winding region can be increased
Domain, increase the number of turns, accomplish higher inductance value.The side column is elliptic cylindrical, is more favorable for Automated winding, the magnetic core
The corner of body is provided with arc transition structure.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, and is familiar with
The those skilled in the art should be understood that the present invention includes but is not limited to accompanying drawing and interior described in embodiment above
Hold.The modification of any function and structure principle without departing from the present invention is intended to be included in the scope of claims.
