Technical Field

[0001] The utility model relates to the technical field of power adapters, in particular to a power adapter with a replaceable plug. Background Art

[0002] The power adapter, also called an external power supply, is a power supply voltage conversion device for small portable electronic devices and electronic appliances. It is commonly found in small electronic products such as mobile phones, LCD monitors, and laptops. It is generally composed of components such as a housing, a transformer, an inductor, a capacitor, a control IC, and a PCB board. Its working principle is to convert AC input into DC output.

[0003] Currently, the plug on the power adapter is fixed. When the plug is idle or in use, it is easy for the plug to be deformed or broken due to external pressure or operating errors. It is inconvenient to replace the deformed or broken plug, which affects the normal service life of the power adapter. For this reason, we propose a power adapter with a replaceable plug.
