PREVENTION OF ARC TRIP IN SUPPLY CABLE CONNECTION Russian patent published in 2023 - IPC G06F13/20 H01R13/66 H02H9/00 

FIELD: electrical engineering.

SUBSTANCE: invention is aimed at reducing the likelihood of contact sparking. It is achieved by using a method for controlling the power of a cable data transmission unit, according to which the sensor detects the presence of a user in the immediate vicinity of the connection between the cable plug and the cable socket. In this case, the cable plug and the sensor are part of the cable data transmission unit, the cable data transmission unit additionally contains a cable part connected to the plug, and the sensor is located in the cable plug. A detection signal is generated by the sensor in response to presence detection, and the level of a power signal transmitted between the cable plug and the cable socket is reduced in response to the detection signal.

EFFECT: reducing the likelihood of contact sparking.
