Abstract: A flexible socket of a power source hub is provided. The input terminal of the hub is electrically connected with a power source. The hub distributes the power source into a plurality of output terminals including first electrodes, second electrodes and ground electrodes. A plurality of sockets extend out from the output terminals via 3-strand cables. Each socket includes three holes corresponding to the first electrode, the second electrode, and the ground electrode. The three-hole sockets are designed to open in a first direction. The strands of the 3-strand cable are arranged one on top of the other in the first direction and extended outside the hub in a second direction substantially perpendicular to the first direction. In this way, it is easy to bend and displace sockets sideways to facilitate the plug-in of the plugs.

Abstract: A current-transformed power source connecting circuit device comprises a power source plug-in, in connection with an external power source; a current transformer, having a primary and a secondary windings, the primary winding of which is connected in series to a current path of the power source plug-in for detection of a current; a main socket, capable of connecting externally to a main electrical apparatus, one end of which is connected to the current transformer; a rectifying means, in connection with the secondary winding of the current transformer, for rectification of a current from the current transformer; a switching means, for receiving a voltage from the rectifying means, which is switched on at a time that the received voltage is sufficient and switched off at a time that the voltage is insufficient; and at least one subsidiary socket, for connecting with the switching means and parallel-connection with the main socket, capable of connecting to a peripheral electrical apparatus.
