Abstract
The invention discloses a thin-shaped transformer with an aluminum shielding plate. The thin-shaped transformer comprises a magnetic core, a primary winding unit, a secondary winding unit and an aluminum plate, wherein the primary winding unit and the secondary winding unit are arranged on the same framework; the magnetic core is inserted into an inserting groove of the framework; and the aluminum plate is arranged on the framework. The thin-shaped transformer with the aluminum shielding plate has a reasonable design, can greatly improve the anti-interference internal force, improves the space utilization rate of the transformer and enables the transformer to meet the miniaturization requirements; and meanwhile, the primary winding unit and the secondary winding unit are separated to inhibit magnetic flow leakage and parasitic capacitance between the windings, so that the transformer is ensured to work normally and effectively.
Description
Technical field
The present invention relates to a kind of transformer, especially a kind of thin type transformer with the aluminium barricade.
Background technology
Slimming, miniaturization along with electronic product; The volume of electronic transformer also is asked to more and more littler, more and more thinner, and this causes the layout of circuit board element more and more intensive; On the other hand; The transformer of power supply is in order to reduce volume, operating frequency by before tens KHzs rise to the hundreds of KHz, have in addition reach megahertz.Because the dense layout of components and parts and the raising of operating frequency, the electromagnetic interference between the components and parts is more and more serious, and machine product is increasing through the difficulty of EMI/EMC relevant criterion, and transformer is the topmost interference source of complete machine EMI.
Summary of the invention
Goal of the invention: the objective of the invention is in order to solve the deficiency of prior art, a kind of advantages of small volume is provided and can reduces the transformer that complete machine EMI is disturbed.
Technical scheme: in order to realize above purpose, a kind of thin type transformer with the aluminium barricade of the present invention comprises magnetic core, elementary winding element, secondary winding unit, aluminium sheet; Described elementary winding element and secondary winding unit are located on the same skeleton, and described magnetic core is plugged in the slot of skeleton, and described aluminium sheet is arranged on the skeleton.
Described magnetic core is a FERRITE CORE.
The thickness of described aluminium sheet is 0.5-0.8mm.
Adopt ambroin separately between described elementary winding element and the secondary winding unit.
Described aluminium sheet is pasted on skeleton.
Beneficial effect: the present invention reasonably designs; Significantly promoted anti-interference internal force; Improved the space availability ratio of transformer, made transformer meet the requirement of miniaturization, the present invention simultaneously also suppresses the parasitic capacitance between flux leakage and winding through isolating elementary winding element and secondary winding unit; Guaranteed that transformer is normal, effectively work.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a front view of the present invention;
Wherein: 1, magnetic core, 2, elementary coiling unit, 3, the secondary rolling thread unit, 4, aluminium sheet, 5, skeleton.
Embodiment
Further illustrate the present invention below in conjunction with accompanying drawing.
Shown in Figure 2 like Fig. 1, a kind of thin type transformer with the aluminium barricade comprises magnetic core 1, elementary winding element 2, secondary winding unit 3, aluminium sheet 4; Described elementary winding element 2 is located on the same skeleton 5 with secondary winding unit 3; 1 pair of described magnetic core is inserted and is installed in the slot of skeleton 5, and makes both sides magnetic core 1 be connected to form an overall structure through adhesive tape, and described magnetic core 1 is a FERRITE CORE; When guaranteeing permeability, can reduce the number of turns of coil; Reduce the purpose of volume of transformer greatly, an aluminium sheet 4 is pasted at described skeleton 5 tops, and the thickness of described aluminium sheet 4 is 0.5-0.8mm; Effectively shield electromagnetic interference guarantees the normal operation of body.Adopt ambroin can effectively suppress the parasitic capacitance between flux leakage and winding between described elementary winding element 2 and the secondary winding unit 3, guaranteed that transformer is normal, effectively work.
The foregoing description only is explanation technical conceive of the present invention and characteristics, its objective is to let to be familiar with these those skilled in the art and can to understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalents that spirit has been done according to the present invention or modification all should be encompassed within protection scope of the present invention.
