Description
Technical field
The present invention relates to a kind of FERRITE CORE, belong to FERRITE CORE manufacturing technology field.
Background technology
Magnetic core is meant a kind of sintering magnetic metal oxide of being made up of various iron oxide mixtures.For example, manganese-zinc ferrite and nickel-Zn ferrite are typical magnetic core array materials.
Manganese-zinc ferrite has the characteristics of high magnetic permeability and high magnetic flux density, and when being lower than the frequency of 1MHz, has more low-loss characteristic.
Nickel-Zn ferrite has high unit area impedance, less than the characteristics such as low magnetic permeability of hundreds of, and also produce than low-loss in the frequency that is higher than 1MHz etc.
FERRITE CORE is used for the coil and the transformer of various electronic equipments; It is a kind of high frequency permeability magnetic material (the same silicon steel sheet of principle only is used in high frequency environment), mainly makees high frequency transformer (as Switching Power Supply; Line output transformer etc.), high frequency magnet ring (anti-interference usefulness) or the like.
ETC type magnetic core is similar with ET type product in appearance, and it is a kind of a kind of MnZn FERRITE CORE that is widely used in the products such as transformer, electricity-saving lamp, the distinguishing feature that volume is little, the inductance height is this kind of magnetic core.
The newel of the ET type magnetic core that uses at present is the shape that is similar to cuboid, and when it was wound the line, such shape was very inconvenient.And, in the coiling of the corner of newel, when the coiling dynamics changes, very easily cause coil asymmetric, thereby cause the heating phenomenon.
In order to overcome the problems referred to above; Some solutions are also arranged at present, for example four corners of newel are done greatly, like this newel just become " plentiful " and " mellow and full "; Be similar to cylinder; Though way can conveniently wind the line like this, such structure is extremely inconvenient for the production of product, is unfavorable for the large-scale manufacturing.
Summary of the invention
Technical problem to be solved by this invention provides and a kind ofly helps to improve coiling quality and efficient, and can improve the FERRITE CORE of inductance.
In order to solve above-mentioned technical problem; Technical scheme of the present invention is: a kind of FERRITE CORE; Its whole frame structure that comprises newel for the centre; The both side surface of said newel is a plane, and the front of said newel, back are cabochon, and the height of said cambered surface is less than or equal to the half the of said cambered surface two ends distance.
In order to obtain better technical effect, improve coiling quality and efficient, improve inductance value, the height of said cambered surface equals the half the of said cambered surface two ends distance.
The cross section that the present invention is different from conventional ET type product center post is a similar square shape; Wherein heart column section is the shape that is similar to the playground, and when coiling, level and smooth cambered surface makes things convenient for winding operation; And can not cause coil asymmetric because of the change of coiling dynamics size.
The shape of newel of the present invention makes the newel cross section of section ratio ET type product of newel want big; The newel volume that is shape of the present invention is big; And its inductance height of the product of this type mainly is to concentrate on the center pillar; For two products of equal height, the inductance of product of the present invention increases.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed explanation.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a sectional view of the present invention.
Fig. 3 is the sketch map of newel of the present invention.
Embodiment
As shown in Figure 1, the integral body of FERRITE CORE 1 of the present invention is for being the frame structure of " day " font, comprises newel 2 between wherein.
By Fig. 1; Particularly Fig. 2 can clearly be seen that; Said newel 2 changes traditional rectangular shape; Both side surface 3 and the front 4, the back 4 ' that are traditional newel 2 are plane, and the both side surface 3 of newel 2 of the present invention be a plane, the front 4 of said newel, 4 ' are cabochon at the back.Like this, newel 2 cross sections are the shapes that are similar to the playground, and when coiling, level and smooth cambered surface makes things convenient for winding operation, and can not cause coil asymmetric because of the change of coiling dynamics size.
In addition, the shape of newel 2 makes newel 2 cross sections of the ET type product that the section ratio of newel 2 is common want big, and inductance is increased.
At last, newel 2 structures of the present invention can make on newel 2 dress mould in the shell coiling more smoothly.
Of Fig. 3, the height h of said cambered surface is less than or equal to the half the of said cambered surface two ends distance L, and what the height h of cambered surface should not be greater than said cambered surface two ends distance L is half the, promptly greater than semi-circular shape, is unfavorable for that dress is moulded the shell coiling on newel 2.
In order to obtain effect preferably, the height of said cambered surface equals the half the of said cambered surface two ends distance.
The invention solves the problem of coiling, obtain higher inductance value, and newel 2 shapes make that moulding shell loads onto the convenient rotation in back.
The foregoing description does not limit the present invention in any way, and every employing is equal to the technical scheme that replacement or the mode of equivalent transformation obtain and all drops in protection scope of the present invention.
Claims (2)
1. a FERRITE CORE (1); Its integral body comprises the frame structure of newel (2) for the centre; It is characterized in that: the both side surface (3) of said newel (2) is plane; The front of said newel (4), at the back (4 ') be cabochon, the height of said cambered surface is less than or equal to the half the of said cambered surface two ends distance.
2. FERRITE CORE according to claim 1 (1) is characterized in that: the height of said cambered surface equals the half the of said cambered surface two ends distance.
