[0002] High frequency transformer is a power transformer with working frequency exceeding medium frequency (10kHz). It is mainly used as high frequency switching power transformer in high frequency switching power supply, and also used as high frequency inverter power transformer in high frequency inverter power supply and high frequency inverter welding machine. According to the working frequency, it can be divided into several grades: 10kHz-50kHz, 50kHz-100kHz, 100kHz~500kHz, 500kHz~1MHz, and above 10MHz.

[0003] Currently in the high frequency transformers with model PQ2620 or PQ2625, such as Figure 6 and Figure 7 As shown, wire A 4 and wire B 5 will extend out from the winding for wiring, and the other pins 2 will be directly plugged into the circuit board. Since the plated wire lengths of wire A 4 and wire B 5 are short, they are prone to falling off during soldering after insertion, resulting in a high defect rate. In addition, wires are prone to bouncing up during soldering, posing certain safety hazards. In addition, wire A 4 and wire B 5 will diverge from each other, making it inconvenient to organize.
