Ultrathin high-frequency transformer

The utility model relates to the technical field of switch transformers, in particular to an ultrathin high-frequency transformer which comprises a framework, a primary winding, a secondary winding and two magnetic cores. Winding posts are arranged on the two sides of the framework, a primary winding and a secondary winding are wound on the winding posts on the two sides respectively, slots matched with the middle parts of the E-shaped magnetic cores are formed in the upper part and the lower part of the framework, and the E-shaped magnetic cores are combined on the upper part and the lower part of the framework and are wound and fixed by insulating tapes, so that the transformer can be assembled. The assembled transformer is assembled in a groove of the PCB and sinks to a certain height, and the two sides of the second framework plate are provided with the inverted-L-shaped crab-foot-shaped pins, so that it is guaranteed that the framework can sink into the middle of the PCB. According to the utility model,
