A power converter is provided. A power communication module controls a secondary side voltage control circuit to output a voltage control signal according to a connection state signal. A primary side switch control circuit adjusts an operating frequency of switching a conduction state of an adjustment switch according to the voltage control signal, so as to adjust an output voltage of a transformer circuit.

A low-power-consumption protection circuit includes a load detection module, a secondary feedback control module, and a primary control module. The load detection module is coupled to a current detection unit. The secondary feedback control module is coupled to the load detection module and an isolation unit. The primary control module is coupled to the isolation unit and an isolation switch. When the load detection module detects that the current detection unit outputs a voltage level, the secondary feedback control module transmits a protection signal to the primary control module through the isolation unit.

Low-power-consumption protection circuit

A connector is fixed in an opening of a housing of an electronic device. The connector comprises a main body housed in the opening, a gasket and a securing member. The main body comprises a plug portion, and an engaging portion connecting the plug portion. Furthermore, an engaging groove located on the engaging portion adjacent to the plug portion. The gasket located between the between the plug portion and the housing. The engaging portion sequentially passes through the gasket and the opening to make a part of the engaging groove away from the plug portion is located a side of the housing. The securing member partly engaged in the engaging groove and sandwiched between the engaging portion and the housing to fix the main body to the housing.
