[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil, and iron core. In electrical equipment and wireless circuits, transformers are often used to increase or decrease voltage, match impedance, and provide safety isolation. A transformer is a device that uses electromagnetic mutual induction to transform voltage, current, and impedance. In a transformer, the transformer lead wire needs to be led out of the transformer through the transformer lead wire structure.

[0003] The lead wire structure on the existing transformer is usually provided with a circular through-hole. When lead wires of different thicknesses pass through the through-hole, due to the difference in diameter between the through-hole and the lead wire, they are usually wrapped together and passed through the through-hole together. However, since multiple lead wires are entangled together, the heat accumulated in the lead wires is difficult to dissipate, thus causing safety accidents. Utility Model Content
