Description
Technical field
The utility model relates to field transformer, particularly relates to a kind of high frequency transformer.
Background technology
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, current high frequency transformer normally by winding around in frame center, magnetic core is fixed on skeleton, then insulating tape is superscribed at skin, the transformer leakage inductance of this structure is large, and efficiency is low, poor anti jamming capability, shield effectiveness is bad, and EMI effect is also bad.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of shield effectiveness good, and antijamming capability is strong, the simple high frequency transformer of structure.
For reaching above-mentioned technique effect, the technical solution adopted in the utility model is:
A kind of high frequency transformer, it is characterized in that: comprise transformer body and metal cover board, described transformer body is connected by buckle with metal cover board, described transformer body comprises magnetic core, skeleton, stitch, winding and insulating tape, described magnetic core is fixedly connected with skeleton, and magnetic core outer surface is provided with one deck insulating tape, and described stitch is fixedly connected with skeleton, described winding is wrapped in frame center, and skin is provided with insulating tape.
Further, the two sides that described skeleton one is relative are respectively provided with two buckle boss.
Further, described metal cover board is the cuboid housing of an opening, and described metal cover board is provided with the block button hole matched with the buckle boss of skeleton on the sidewall at the position near opening.
The beneficial effects of the utility model are: described high frequency transformer comprises transformer body and metal cover board, described transformer body is connected by buckle with metal cover board, magnetic core outer surface is provided with one deck insulating tape, winding skin is provided with insulating tape, this makes structure simple, shield effectiveness is good, and antijamming capability is strong.
Accompanying drawing explanation
Fig. 1 is the perspective view of the utility model high frequency transformer.
