[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 supply transformer in a high-frequency switching power supply. It is also used as a high-frequency inverter power supply transformer in a high-frequency inverter power supply and a high-frequency inverter welding machine.

[0003] In actual applications, a layer of insulating tape is glued to the outside of the coil to protect the coil. When a slight collision occurs, the insulating tape can provide a certain degree of protection for the coil. However, high-frequency transformers may face impacts from the external environment during production and transportation, and the protective effect of the insulating tape is almost negligible, so that the impact may cause damage to the transformer, especially its fragile external structure and key components. The damaged components will affect the normal use of the transformer. Therefore, we propose a high-frequency transformer with a protective structure. Utility Model Content
