Abstract
A power extension wire includes a power plug, a socket, and a cord connected between the power plug and the socket. The power plug includes a wireless transmission module, the socket includes an alternating-current jack and a current converting unit. The cord includes a plurality of alternating-current conducting wires and at least one direct-current conducting wire. The current converting unit receives an alternating-current power through the alternating-current conducting wires and provides a direct-current power to the wireless transmission module through the direct-current conducting wire.

A power extension wire, comprising:
- a power plug, the power plug has a wireless transmission module;
- a socket, the socket has at least one alternating-current jack and a current converting unit;
- and
- a cord connected between the power plug and the socket, the cord has a plurality of alternating-current conducting wires and at least one direct-current conducting wire;
- the current converting unit receives an alternating-current power through the plurality of alternating-current conducting wires, and the current converting unit supplies power to the wireless transmission module through the at least one direct-current conducting wire.
A power extension wire, comprising:
- a power plug, the power plug has a first temperature sensor element;
- a socket, the socket has at least one alternating-current jack;
- and
- a cord connected between the power plug and the socket, the cord has a plurality of alternating-current conducting wires and at least one direct-current conducting wire;
- wherein when a temperature sensed by the first temperature sensitive element is higher than a first threshold value, the first temperature sensor element transmit a first sense signal to the socket through the at least one direct-current conducting wire.
