Description
[technical field]
This utility model relates to a kind of E-type magnetic core, a kind of E-type magnetic core for transformator.
[background technology]
Magnetic core is applied in coil or the transformator of various electronic equipment, and the structure of industry magnetic core has a lot, is generally divided into
C, O, E shapes etc., different structure functions is different, and manufacturer produces the magnetic core of different structure according to the different demands of client, i.e.
Making is all E shape structure, but fine distinction also can make function variant, such as heat radiation, function of shielding.According to various ferrites
The performance of material, can be selected to the magnetic core of coupling, due to the power consumption of power ferrite material in different frequency ranges
It is negative relation with temperature, such that it is able to meet the needs that switching mode power supply transformer requirement heating is little, when high-intensity magnetic field, power attenuation
The least, bigger output can be produced.
Therefore, it is necessary to design a kind of good E-type magnetic core, to overcome the problems referred to above.
[utility model content]
For background technology problem encountered, the purpose of this utility model is to provide a kind of by arranging groove change
The E-type magnetic core of function of shielding.
For achieving the above object, this utility model employing techniques below means:
A kind of E-type magnetic core, it includes that a center pillar is centrally located, in center pillar be respectively provided on two sides with a first side and
One second side, body after the rear side of center pillar is provided with, this rear body connection first side, center pillar and second side, first
It is collectively forming a window between side, second side and center pillar, has been formed many on first side or second side or center pillar
Individual groove.
Further, the dual-side of center pillar is respectively provided with multiple first groove and multiple second groove.Multiple first grooves
With multiple second equal symmetry arrangement of groove.
Further, first side, near center pillar side, has multiple 3rd groove, second side near center pillar side,
There is multiple 4th groove.Multiple 3rd grooves and multiple 4th equal symmetry arrangement of groove.
Further, the dual-side of center pillar is respectively provided with chamfering.The end face of rear body is further provided with a breach.
Further, between first side and center pillar window width and between second side and center pillar, the width of window is not
Identical.
Compared with prior art, this utility model has the advantages that
When E-type magnetic core is applied on transformator, multiple recessed owing to being formed on first side or second side or center pillar
Groove, after such wire is wound on center pillar, at least part of wire can enter in multiple groove, and such function of shielding is good, because recessed
The wall of groove periphery can shield, although additionally, offer multiple groove so that center pillar or first side or second side
Material reduce, but owing to the wall of recessed circumferential has increase thickness, also output will not be impacted, simultaneously as
The setting of groove, the space of window is bigger, can more improve the output of transformator with the more wire of coiling.
[accompanying drawing explanation]
Fig. 1 is the schematic diagram of this utility model E-type magnetic core.
The drawing reference numeral explanation of detailed description of the invention:
| Center pillar 1 | First groove 11 | Second groove 12 |
| Chamfering 13 | First side 2 | 3rd groove 21 |
| Second side 3 | 4th groove 31 | Rear body 4 |
| Breach 41 | Window 5 |
[detailed description of the invention]
For ease of being better understood from the purpose of this utility model, structure, feature and effect etc., in conjunction with accompanying drawing with concrete
The utility model is described in further detail for embodiment.
This utility model E-type magnetic core constitutes transformator (not shown) in order to coiling multiple conducting wires (not shown).
Referring to Fig. 1, E-type magnetic core includes that a center pillar 1 is centrally located, is respectively provided on two sides with one first in center pillar 1
Side 2 and a second side 3, body 4 after the rear side of center pillar 1 is provided with, this rear body 4 connects first side 2, center pillar 1 and
Second side 3, has been collectively forming a window 5 between first side 2, second side 3 and center pillar 1, the dual-side of center pillar 1 has respectively
There are multiple first groove 11 and multiple second groove 12, multiple first grooves 11 and multiple second equal symmetry arrangement of groove 12, side
Just coiling wire, and stable output power.First side 2, near center pillar 1 side, has multiple 3rd groove 21, second side 3
Near center pillar 1 side, there is multiple 4th groove 31.Multiple 3rd grooves 21 and multiple 4th equal symmetry arrangement of groove 31, side
Just coiling wire, and stable output power, and then the reduction of coiling expense, the manufacturing cost of whole transformator reduces, and yield is high.
Certainly, can also be that only first side 2 is provided with the 3rd groove 21 in other embodiments, or only to be provided with the 4th recessed in second side 3
Groove 31, or the dual-side of only center pillar 1 is respectively equipped with the first groove 11, as long as technique for coiling, function of shielding and output can be improved
Power problem.
Referring to Fig. 1, it addition, the dual-side of center pillar 1 is respectively provided with chamfering 13, assembling is simple, and the motility of installation is good, and
And when being possible to prevent coiling wire, the colloid outside wire is carried out scratch, further ensures product yield.Rear body 4
End face is further provided with a breach 41, it is simple to heat radiation.Between first side 2 and center pillar 1 width of window 5 and second side 3 and
Between center pillar 1, the width of window 5 differs (not shown), the misloading when of being so possible to prevent to install, and i.e. has the merit of fool proof
Energy.
Refer to Fig. 1, when E-type magnetic core is applied on transformator, due on first side 2 or second side 3 or center pillar 1
Being formed with multiple groove, after such wire is wound on center pillar 1, at least part of wire can enter multiple first groove 11, multiple
In second groove 12, multiple 3rd groove 21, multiple 4th groove 31, such function of shielding is good, because multiple first groove 11,
Multiple second grooves 12, multiple 3rd groove 21, the wall of multiple 4th groove 31 periphery can shield, although additionally,
Offer multiple first groove 11, multiple second groove 12, multiple 3rd groove 21, multiple 4th groove 31 so that center pillar 1 or
The material of first side 2 or second side 3 reduces, but due to multiple first grooves 11, multiple second groove 12, multiple 3rd recessed
Groove 21, the wall of multiple 4th groove 31 periphery have increase thickness, also will not impact output, simultaneously as many
Individual first groove 11, multiple second groove 12, multiple 3rd groove 21, the setting of multiple 4th groove 31, the space of window 5 is more
Greatly, the output of transformator can more be improve with the more wire of coiling.
It addition, above-mentioned structure, the expense of E-type magnetic core is low many, adds coiling and assembles the most fairly simple, this
Core shapes is the most most widely used, the problem simultaneously also solving shielding, and general high power inductors and transformator can make
With the E-type magnetic core of above-mentioned structure.
Detailed description above is only the explanation of the preferred embodiment of this utility model, non-therefore limit to of the present utility model specially
Profit scope, so, the equivalence techniques change that all utilization this creation description and diagramatic content are done, it is both contained in this utility model
The scope of the claims in.
