Abstract: The present invention relates to a socket having loading detecting function, which comprises: a housing; at least a socket; a sensor; a relay; a detection circuit capable of detecting the loading value of the socket; and a control unit. The control unit can be used for recording the maximum of the loading value, and said maximum is multiplied by an coefficient thereby obtaining a first threshold value; meanwhile comparing the loading value to the first threshold value and a second threshold value, when the loading value is lower than both of the first threshold value and the second threshold value, the control unit terminates the relay after a second time period for cutting off the electric source of the socket.

Abstract: The present invention relates to a dynamic energy-saving socket which comprises: a housing; a first socket; a sensor; a first relay; an active/passive sensing circuit; at least a second socket; a second relay; and a control unit. When a human is approaching the sensor, the first relay is enabled to be conducted for supplying electric source to the first socket, and when the loading value of the first socket exceeds a threshold value, the second relay is enabled to be conducted for supplying the electric source to the second socket, thereby achieving the objective of saving energy.
