Abstract
The utility model discloses a kind of EFD type soft-magnetic ferrite core green part, comprise the newel being positioned at described green part center and the supporting leg being positioned at described newel both sides, the top of described newel and described supporting leg is provided with leg and seals.Described leg enclosuring structure is processed into finished product EFD type magnetic core after green part has sintered by polishing.Compared with prior art, the advantage of being out of shape, dimensional uniformity is good, rate of finished products is high is not easy when the utility model has green sintering.
Description
Technical field
The utility model relates to a kind of ferrite core green part, particularly relates to a kind of LED display power supply transformer EFD type finished product magnetic core green part.
Background technology
Along with the development of flat panel display, light-emitting diode display part is slimming and wide screen more and more.Magnetic core is as the core component of LED display power supply transformer, and its size is more and more slimming also, and the power that can carry is increasing.Traditional E E type equal-specification magnetic core can not meet the requirement of LED flat plate display.EFD type magnetic core because of its good heat dissipation effect, the power that can carry is high and be applied.But EFD type magnetic core easily produces sintering warpage because leg longwell is thin, make this finished product rate low, cost of manufacture is high.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of EFD type soft-magnetic ferrite core green part, effectively can solve magnetic core and hold yielding problem when sintering, improve rate of finished products, reduce production cost.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
There is provided a kind of EFD type soft-magnetic ferrite core green part, comprise the newel being positioned at described green part center and the supporting leg being positioned at described newel both sides, the top of described newel and described supporting leg is provided with leg and seals.
In the utility model preferred embodiment, the shape of described newel is rectangle.
In the utility model preferred embodiment, the thickness of described leg sealing is 0.5 ~ 5.0mm.
In the utility model preferred embodiment, after described green part is burnt till, described leg sealing obtains finished product EFD type magnetic core after being removed by mill processing.
In the utility model preferred embodiment, the height of described finished product EFD type magnetic core is 26.60mm ~ 27.00mm, and width is 6.55mm ~ 6.95mm, and length is 43.50mm ~ 44.50mm.
In the utility model preferred embodiment, the height of described finished product EFD type magnetic core is 26.80mm, and width is 6.75mm, and length is 44.00mm.
The beneficial effects of the utility model are: a kind of EFD type of the utility model soft-magnetic ferrite core green part, the top of newel and supporting leg is provided with leg seal, make this green part sinter time bottom consistent with the contraction of supporting leg, decrease green part and produce deformation when sintering because shrinking difference, make the dimensional uniformity of final finished product EFD type magnetic core good, rate of finished products brings up to more than 98% from less than 62%.
Accompanying drawing explanation
Fig. 1 is the perspective view of the utility model one preferred embodiment;
Fig. 2 is the front view of Fig. 1;
Fig. 3 is the left view of Fig. 1;
Fig. 4 utilizes above-mentioned preferred embodiment shown in the drawings to sinter the perspective view of the finished product EFD type magnetic core made;
In accompanying drawing, the mark of each parts is as follows: 1, newel, and 2, supporting leg, 3, leg sealing.
embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection range of the present utility model.
Embodiment:
EFD44 type soft-magnetic ferrite core green part, structure is as shown in Fig. 1 ~ 3, comprise the newel 1 being positioned at described green part center and the supporting leg 2 being positioned at described newel 1 both sides, the shape of described newel 1 is rectangle, described newel 1 is provided with leg with the top of described supporting leg 2 and seals 3, and the thickness of described leg sealing 3 is 0.5 ~ 5.0mm.
After described green part is burnt till, mill processing is carried out to it, described leg sealing 3 is ground off and obtains finished product EFD type magnetic core, its structure as shown in Figure 4, the height of described finished product EFD type magnetic core is 26.80mm ± 0.20mm, and width is 6.75mm ± 0.20mm, and length is 44.00mm ± 0.50mm.
The utility model seals 3 owing to being provided with leg at newel 1 with the top of supporting leg 2, make this green part sinter time bottom consistent with the contraction of supporting leg 2, decrease green part and produce deformation when sintering because shrinking difference, make the dimensional uniformity of final finished product EFD type magnetic core good, rate of finished products brings up to more than 98% from less than 62%.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
