Abstract
The invention discloses a high utilization rate magnetic core which comprises a magnetic core body and a middle column integrally formed with the magnetic core body. The magnetic core body comprises a base, a first edge leg and a second edge leg, wherein the base is integrally formed to be of a semi-surrounded structure, and the first edge leg and the second edge leg are symmetrically arranged at the two ends of the base. The middle column is arranged in the middle of the base, and the length direction and the width direction of the middle column are both consistent with the length directions and the width directions of the first edge leg and the second edge leg. The inner side faces, adjacent to the middle column, of the first edge leg and the second edge leg are arc-shaped faces, and the arc-shaped faces are formed in the direction away from the middle column. The middle column is a kidney-shaped column with the two ends being big and the middle being decreased gradually, and the position between the middle column and the first edge leg and the position between the middle column and the second edge leg on the base are respectively provided with a fusiform-like groove. The high utilization rate magnetic core has the advantages that the structure is novel, the body is of the semi-surrounded structure, the middle column is the kidney-shaped column with the two ends being large and the middle being decreased gradually, the fusiform-like grooves are formed in the base, the output power is improved, compared with products of the same type in the market, the output power is improved by more than 20%, and the output efficiency is improved by more than 15%.
Description
Technical field
The present invention relates to a kind of magnetic core, be specifically related to a kind of high usage magnetic core that can take into account magnetic core delivery efficiency and power output.
Background technology
Development along with electronic technology, product is miniaturization and compact conformation more and more, therefore, the magnetic core bulky, delivery efficiency is low will be eliminated by market, the substitute is the small and exquisite magnetic core of a series of structures, the sectional area of magnetic core center pillar has determined the size of magnetic flux, has also just determined power output; And window (being the space between center pillar and limit leg) determined can around coil turn, coil turn is more or sectional area is larger, delivery efficiency is just higher, so, how to take into account magnetic core delivery efficiency and power output, to reduce the wastage be the study hotspot on market.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of novel magnetic core of taking into account delivery efficiency and power output.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
A kind of magnetic core of high usage, comprise magnetic core main body and with the integrated center pillar of magnetic core main body, it is the base of semi-surrounding structure, the first side leg that is symmetricly set in base two ends and Second Edge leg that described magnetic core main body comprises one-body molded, and it is all consistent with first side leg and Second Edge leg with short transverse that described center pillar is arranged at centre and its length direction of base; The medial surface that described first side leg and Second Edge leg are adjacent with center pillar is arcwall face, and arcwall face forms to the direction away from center pillar; Described center pillar is large, the middle gradually little kidney-shaped posts in two ends, is equipped with class fusiformis groove on the base between described center pillar and first side leg, Second Edge leg, and such core structure can guarantee that power output is larger, and reduces the wastage, improves delivery efficiency.
In order further to reduce the wastage, aforementioned first side leg and Second Edge leg are contour, and the height of described center pillar is lower than the height of described first side leg and Second Edge leg; The length of aforementioned center pillar is less than the length of first side leg and Second Edge leg.
Preferably, the groove depth of stating class fusiformis groove is the 1/3-1/2 of base thickness.
Further, the length of aforementioned class fusiformis groove is identical with the length of center pillar.
Usefulness of the present invention is: magnetic core of the present invention, and novel structure, main body is semi-surrounding structure, center pillar is large, the middle gradually little kidney-shaped posts in two ends, and on base, is provided with class fusiformis groove, has improved power output, than product of the same type on market, power output improves more than 20%; Structure by further opposite side leg, center pillar, class fusiformis groove and dimensionally-optimised simultaneously, window area increases, and has reduced loss, improves delivery efficiency more than 15%.
Accompanying drawing explanation
Fig. 1 is the perspective view of the magnetic core of a kind of high usage of the present invention.
The implication of Reference numeral in figure: 1, center pillar, 2, base, 3, first side leg, 4, Second Edge leg, 5, class fusiformis groove.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.
Referring to Fig. 1, the magnetic core of a kind of high usage of the present invention, comprise magnetic core main body and with the integrated center pillar 1 of magnetic core main body.Wherein, magnetic core main body comprises that one-body molded is the base 2 of semi-surrounding structure, the first side leg 3 that is symmetricly set in base 2 two ends and Second Edge leg 4.As shown in Figure 1, it is all consistent with first side leg 3 and Second Edge leg 4 with short transverse (i.e. vertical Z-direction in figure) that center pillar 1 is arranged at centre and its length direction (i.e. Y direction in figure) of base 2; The medial surface that first side leg 3 is adjacent with center pillar 1 with Second Edge leg 4 is arcwall face, thereby arcwall face is bent to form to increase window area to the direction away from center pillar 1, increases power output; Center pillar 1 is for two ends are large, the gradually little kidney-shaped post in centre increases the sectional area of coil further to increase window area simultaneously.As shown in Figure 1, be equipped with class fusiformis groove 5 on the base 2 between center pillar 1 and first side leg 3, Second Edge leg 4, the setting of groove can reduce the loss of magnetic core, improves delivery efficiency.So, the magnetic core of this structure not only can be guaranteed larger power output, can also reduce the wastage simultaneously, improves delivery efficiency, has solved at low cost puzzlement a great problem in the industry.
In order further to reduce the wastage, first side leg 3 and Second Edge leg 4 are contour, and the height of center pillar 1 is lower than the height of described first side leg 3 and Second Edge leg 4; And the length of center pillar 1 is less than the length of first side leg 3 and Second Edge leg 4.So, center pillar 1 just " is coated " between base 2, the first supporting leg and the second supporting leg, and loss reduces greatly.
Preferably, the groove depth of stating class fusiformis groove 5 is the 1/3-1/2 of base 2 thickness, and the length of class fusiformis groove 5 is identical with the length of center pillar 1, further to reduce the wastage, improves delivery efficiency.
Magnetic core of the present invention, power output and delivery efficiency are improved simultaneously, compare with the magnetic core with similar volume and agent structure, and power output improves more than 20%, and delivery efficiency improves more than 15% simultaneously, and this magnetic core has good market prospects.
More than show and described basic principle of the present invention, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
