Description

Technical Field

[0001] The utility model relates to a micro electronic transformer, belonging to the technical field of electronic devices. Background Art

[0002] An electronic transformer is an electronic device that converts the alternating voltage of the mains into direct current and then outputs a high-frequency AC voltage through semiconductor switching devices, electronic components and high-frequency transformer windings. It is also an AC-DC-AC inverter circuit described in electronics theory. It is mainly composed of a high-frequency transformer core and two or more coils, which do not change their positions. From one or more electrical circuits, AC power is converted into AC voltage and current through electromagnetic induction.

[0003] During the use of existing micro electronic transformers, the external wires at the pins are usually connected by soldering. This method is not only inefficient, but also difficult to quickly disassemble after the external wires fail, and it is easy to damage the pins. When installing the electronic transformer, the installation part usually needs to be quickly bolted according to the size of the electronic transformer. The bolt fixing method not only has slow disassembly and assembly efficiency, but also makes it difficult to disassemble and replace electronic transformers of different sizes, thereby affecting the disassembly and assembly of different electronic transformers.
