Abstract: A connector leakage protection system includes a current foldback module with a first end coupled to an output port of a DC power supply; an anti-interference module with a first end coupled to a second end of the current foldback module, and a second end coupled to a power port of a connector; and a leakage protection module between the output port and the first end of the current foldback module, or the second end of the current foldback module and the first end of the anti-interference module, or the second end of the anti-interference module and the power port. When the output port outputs a DC voltage, the leakage protection module is switched on. When the output port does not output the DC voltage, the leakage protection module is switched off, preventing current leakage from flowing to the output port. A connector leakage protection circuit is also provided.

Abstract: A motherboard includes a power module, a display module, a control module, and a protection module. The protection module is coupled to the power module, the display module, and the control module. The control module is capable of outputting a first control signal to control the protection module to connect the power module to the display module to be powered by the power module or disconnect the power module from the display module.

Abstract: An anti-leakage supply circuit includes a power supply unit, an output unit, a control unit, and a control circuit. The control unit is configured to output a control signal. The output unit is configured to be switched on after receiving the control signal and to output an output voltage after being switched on and receiving a voltage from the power supply unit. The control circuit is configured to be switched on after an electronic device is in a normal state. The output unit is configured to connect to the interface after the control circuit is switched on, thereby enabling the output unit to output the output voltage to supply to an interface. The control circuit is further configured to be switched off after the electronic device is in a shutdown state, thereby disabling the output voltage supply to the interface.
