High frequency transformer is as the topmost part of Switching Power Supply, is the vitals carrying out energy storage and transmission.Along with the development of power electronic technology, Switching Power Supply relies on the feature of its high frequency to be widely used in various electronics, electric equipment, among stored-program control exchange, communication, electric power checkout equipment power supply and control appliance power supply, along with the development of power technology, the miniaturization of power-supply system, high frequency and high-power have become an eternal research direction and development trend, current high frequency transformer volume is large, Heavy Weight, and the high and moulding of cost unsightly.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of structure simple, good looking appearance, volume is little, lightweight, the high frequency transformer that cost is low.
For reaching above-mentioned technical purpose, the technical solution adopted in the utility model is:
A kind of high frequency transformer, comprise skeleton, magnetic core, winding, stitch, insulation spacer, insulating tape, it is characterized in that: described skeleton is provided with overhead gage, lower baffle plate and bone core, described stitch is fixedly connected with lower baffle plate, described winding is enamelled wire, be wrapped on bone core uniform close, described winding is wound up as 1 ~ 2 layer on bone core, be wound with some circles from inside to outside, described insulation spacer is located at above lower baffle plate, below winding, described magnetic core is fixedly connected with skeleton, the outer surface of described magnetic core is provided with insulating tape, described magnetic core wherein relative two sides is provided with the cambered surface to central concave, two surperficial intersections upper and lower with it, the other two sides of described magnetic core are set to cambered surface.
Further, described overhead gage, lower baffle plate, bone core are formed in one, and described overhead gage, lower baffle plate are respectively equipped with the limit rib matched with the arc shape of magnetic core.
Further, described stitch is provided with 4, and is located at respectively on 4 angles of lower baffle plate.
Further, the distance between described overhead gage and lower baffle plate is thickness and the winding thickness sum of insulation spacer.Adopt such scheme, the beneficial effects of the utility model are: be wrapped on bone core by described winding uniform close, described winding is wound up as 1 ~ 2 layer on bone core, is wound with some circles from inside to outside, and described magnetic core wherein relative two sides is provided with the cambered surface to central concave, two surperficial intersections upper and lower with it, the other two sides of described magnetic core are set to cambered surface, structure is simple, and volume is little, good looking appearance, save material, reduce cost and weight.
