Abstract

The present invention provides a UBS transmission cable having a power display, comprising a computer-end plug and a device-end plug, wherein the device-end plug internally comprises a signal detection-and-display circuit, and then the circuit drives an indicator for the user to confirm the power supply status of the transmission cable.

Claims

1. A USB transmission cable having a power display, comprising a computer-end plug and a device-end plug, wherein said device-end plug internally comprises a signal detection-and-display circuit, and said circuit drives an indicator to indicate the power supply status of said USB transmission cable.

2. The USB transmission cable having a power display as claimed in claim 1, wherein said computer-end plug can plug into the USB port of a first electronic device, and said device-end plug can plug into the USB port of a second electronic device.

3. The USB transmission cable having a power display as claimed in claim 1, wherein said signal detection-and-display circuit comprises a light-emitting diode and a resistor, and wherein said light-emitting diode and said resistor are connected in series between the power wire and the ground wire.

4. The USB transmission cable having a power display as claimed in claim 1, wherein said signal detection-and-display circuit comprises a transistor and a light-emitting diode, wherein the base of said transistor is connected to the data wire via a resistor;

the collector of said transistor is connected in series to said light-emitting diode and a resistor and then connected to the power wire;

the emitter of said transistor is connected to the ground wire.

5. A USB transmission cable having a power display, comprising a computer-end plug, a device-end plug, and a transmission cable, wherein said transmission cable comprises an inner tube and an outer tube, and the interior of said inner tube comprises the signal wires between said computer-end plug and said device-end plug, a power wire is wound round the external surface of said inner tube, and electro-luminescent materials are filled between said outer tube and said inner tube;

once the power wire is energized, said electro-luminescent materials are caused to become luminescent.

6. The USB transmission cable having a power display as claimed in claim 5, wherein said computer-end plug can plug into the USB port of a first electronic device, and said device-end plug can plug into the USB port of a second electronic device.
