Abstract:
1. A DC/AC adapter assembly having a DC/AC adapter having a circuit board mounted in the adapter and having a controller circuit mounted on the circuit board and configured to control and adjust an output current of the DC/AC adapter; and a socket mounted in the adapter and having a first plurality of contacts aligned in the socket, connecting with the circuit board and one of the contacts of the first plurality of contacts being a detector contact that connects with the controller circuit; a cable configured to connect to the adapter and adapted to connect to a power source, the cable having a distal end and a plug mounted at the distal end of the cable and configured to detachably plug into the socket, send a power-overloading signal to the socket when an electric power of the electricity in the cable exceeds a predetermined maximum load, the plug having a second plurality of contacts corresponding to the first plurality of contacts and configured to contact the first plurality of contacts, a detector contact of the second plurality of contacts configured to contact the detector contact of the first plurality of contacts for transmitting the power-overloading signal from the cable to the socket when the electric power of the electricity in the cable exceeds the predetermined maximum load; and a proximal end having a connector and configured to connect to the power source.
