Abstract

The present disclosure defines a DC socket comprising a positive socket contact (11) and a negative socket contact (12); a linkage detection unit (20) disposed adjacent to the positive socket contact (11) or the negative socket contact (12), and configured to generate a trigger signal in response to a pin (201) of a plug (200) being pulled out from the positive socket contact (11) or the negative socket contact (12) and passing a first position; a mechanical contact switch (30) electrically connected between the positive socket contact (11) and a positive power input terminal (101) of the DC socket, and configured to be closed in response to the pin (201) being inserted into the positive socket contact (11) or the negative socket contact (12) to a second position and be opened in response to the pin (201) being pulled out from the positive socket contact (11) or the negative socket contact (12) and passing the second position, wherein a pulled-out portion of the pin (201) in the second position is longer than that of the pin (201) in the first position; a control circuit (40) electrically connected to the linkage detection unit (20), and configured to generate a control signal lasting for a predetermined duration in response to receiving the trigger signal; and a delayed switching-off unit (50) electrically connected between the positive socket contact (11) and the positive power input terminal (101) and electrically connected to the control circuit (40), and configured to be switched on in response to receiving the control signal from the control circuit (40) and be switched off before the pin (201) is pulled out from the positive socket contact (11) or the negative socket contact (12).
