[0002] A high-frequency transformer is a power transformer with an operating frequency exceeding the medium frequency (10kHz). It is mainly used as a high-frequency switching power transformer in a high-frequency switching power supply, and is also used as a high-frequency inverter power transformer in a high-frequency inverter power supply and a high-frequency inverter welding machine. The current high-frequency transformer generally includes a skeleton, an iron core, a coil, and adhesive tape. The coil is wound around the iron core to form a magnetic core, and the outside of the coil is then wrapped with adhesive tape for insulation. The formed magnetic core is then fixedly mounted on the skeleton. However, the above structure has the disadvantage that a part of the magnetic core will be exposed to the outside, making the whole body easily damaged by external factors, affecting the overall service life. To solve the above problem, the current generally adopted method is to build a protective shell outside the magnetic core, but in this way, the magnetic core is in a closed space, and the heat dissipation effect becomes poor.
