Abstract
The utility model provides a low-noise and energy-saving ferrite core. The low-noise and energy-saving ferrite core is composed of fan-shaped magnetic sheets (1), a magnetic core pillar (2), magnetic core connecting seats (3) and coil grooves (4), and is characterized in that the fan-shaped magnetic sheets (1) are arranged at two corresponding sides of the magnetic core pillar (2) and are connected with the magnetic core pillar (2) through the magnetic core connecting seats (3), and the coil grooves (4) are formed in the fan-shaped magnetic sheets (1). The low-noise and energy-saving ferrite core has the advantages that a round magnetic core central pillar and the fan-shaped magnetic sheets form a whole, the air gap is reduced, and the effective sectional area of a magnetic circuit is increased. Therefore, magnetic flux leakage is reduced, inductance leakage is reduced, and noise is lowered as well.
Description
Technical field
The utility model relates to a kind of FERRITE CORE, relates in particular to the energy-conservation FERRITE CORE of a kind of low noise.
Background technology:
In AC-to DC mains switch conversion transformer, employed EE type or EI type and similar FERRITE CORE, for satisfying the winding requirement, the ratio that the shared bulk of winding need satisfy width and length (highly) is more than or equal to 1.2 rectangle relation.So far, this mains switch conversion flat transformer has two kinds of versions, the first with the general EE type that satisfies the coil window dimensional requirement or El type or similarly the core center post be axis, with this axis as concentric shafts, in the vertical direction, around last a plurality of windings with the adhesive tape insulation, make it overlap transformer at the magnetic core axis, the core axis horizontal direction is used; It two is the EE type and EI type or the similar flat magnetic core that meet the demands, constitutes transformer by first kind of version equally.The transformer of former structure form is difficult to accomplish flat, and the flat transformer leakage inductance of latter's version is big, noise is big, and brings harmful effect can for the perimeter circuit element.
Summary of the invention
The utility model is to provide a kind of low noise energy-conservation FERRITE CORE at the deficiencies in the prior art, to can not exert an influence the FERRITE CORE that is used for flat transformer under the situation of perimeter circuit element, the energy-conservation FERRITE CORE of this low noise, by fan-shaped magnetic sheet, core post, magnetic core Connection Block, the coil groove is formed, in the corresponding both sides of core post fan-shaped magnetic sheet is set, fan-shaped magnetic sheet is connected with core post by the magnetic core Connection Block, at fan-shaped magnetic sheet the coil groove is set.
Order of the present utility model is realized by following technical scheme, developed the energy-conservation FERRITE CORE of a kind of low noise, the energy-conservation FERRITE CORE of this low noise is by fan-shaped magnetic sheet 1, core post 2, magnetic core Connection Block 3, coil groove 4 is formed, and it is characterized in that in core post 2 corresponding both sides fan-shaped magnetic sheet 1 being set, fan-shaped magnetic sheet 1 is connected with core post 2 by magnetic core Connection Block 3, at fan-shaped magnetic sheet 1 coil groove 4 is set.
Described core post 2 is made by Ferrite Material, and wrap wire is arranged on the core post 2 by coil groove 4.
The utility model advantage is: circular core center post and fan-shaped magnetic chip portion constitute an integral body, have not only reduced air gap but also have increased the net sectional area of magnetic circuit, thereby reduced leakage field, have reduced leakage inductance, have also reduced noise.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
See also Fig. 1, the utility model has been developed the energy-conservation FERRITE CORE of a kind of low noise, comprises following steps:
The energy-conservation FERRITE CORE of this low noise is by fan-shaped magnetic sheet 1, core post 2, magnetic core Connection Block 3, coil groove 4 is formed, it is characterized in that in core post 2 corresponding both sides fan-shaped magnetic sheet 1 being set, fan-shaped magnetic sheet 1 is connected with core post 2 by magnetic core Connection Block 3, at fan-shaped magnetic sheet 1 coil groove 4 is set.
Described core post 2 is made by Ferrite Material, and wrap wire is arranged on the core post 2 by coil groove 4.
The announcement of the above embodiment is in order to illustrate the utility model, is not in order to limiting the utility model, so the displacement of the change of numerical value or equivalence element must be subordinate to category of the present utility model such as.
Claims (2)
1. energy-conservation FERRITE CORE of low noise, by fan-shaped magnetic sheet (1), core post (2), magnetic core Connection Block (3), coil groove (4) is formed, it is characterized in that in the corresponding both sides of core post (2) fan-shaped magnetic sheet (1) being set, fan-shaped magnetic sheet (1) is connected with core post (2) by magnetic core Connection Block (3), at fan-shaped magnetic sheet (1) coil groove (4) is set.
