Abstract

A data and power transmitting cable system that includes a first cable conforming to the USB or IEEE1394 standard. The first cable has a power supply wire and several data transmission wires and is plugged into a first port. The first cable provides for transmission of power and data. The system also includes at least one second cable, following the same standard. The second cable includes only power supply wires, with no data transmission wires. The second cable is plugged into a second port, allowing for transmission of additional power.

Claims

1. A data and power transmitting cable system, working in conjunction with a main device port system, which has at least two ports including a first port and a second port, each of said at least two ports having pins for transmitting power and data, and a peripheral device port system, said data and power transmitting cable system comprising:

a first cable, having a power supply line and at least one data line, a main end plugged into said first port of said main device port system and a peripheral end connected with said peripheral device port system, allowing for transmission of power and data; and

at least one second cable, having a main end plugged into said second port of said main device port system and a peripheral end connected with said peripheral device port system, allowing for transmission of additional power from said main device port system to said peripheral device port system.

2. A data and power transmitting cable system according to claim 1, wherein said main end of said second cable has two pins and said peripheral end of said second cable has two pins, which are respectively connected with said two pins of said main end by two wires for transmitting power.

3. A data and power transmitting cable system according to claim 2, wherein said power line of said first cable has two wires which are ohmically connected with said two wires of said second cable.

4. A data and power transmitting cable system according to claim 1, wherein said first and second cables at said peripheral ends thereof have connectors that are distinguishable.

5. A data and power transmitting cable system according to claim 1, wherein said first and second cables have USB connectors.

6. A data and power transmitting cable system according to claim 1, wherein said first and second cables have IEEE1394 connectors.

7. A data and power transmitting cable system according to claim 1, wherein said first cable at said peripheral end thereof has a USB connector and said second cable at said peripheral end thereof has a common power connector.

8. A data and power transmitting cable system according to claim 1, wherein said first cable at said peripheral end thereof has a IEEE1394 connector and said second cable at said peripheral end thereof has a common power connector.

9. A data and power transmitting peripheral connecting system, working in conjunction with a main device port system, which has at least two ports including a first port and a second port, each of said at least two ports having pins for transmitting power and data, and a peripheral device, said peripheral connecting system comprising:

a first cable, having a power supply line and at least one data line, a main end with a connector plugged into said first port of said main device port system and a peripheral end connected with said peripheral device, allowing for transmission of power and data, and

at least one second cable, having a main end with a connector plugged into said second port of said main device port system and a peripheral end, allowing for transmission of additional power from said main device port system to said peripheral device.

10. A data and power transmitting peripheral connecting system according to claim 9, wherein said peripheral end of said at least one second cable is connected with said power supply line of said first cable.

11. A data and power transmitting peripheral connecting system according to claim 9, wherein said peripheral end of said at least one second cable is connected with said peripheral device.

12. A data and power transmitting peripheral connecting system according to claim 9, wherein said peripheral end of said at least one second cable is connected with said peripheral device by a connector having solely power transmitting pins.

13. A data and power transmitting peripheral connecting system according to claim 9, wherein said first and second cables at said main ends thereof have USB connectors.

14. A data and power transmitting peripheral connecting system according to claim 9, wherein said first and second cables at said main ends thereof have IEEE1394 connectors.

15. A data and power transmitting peripheral connecting system, comprising:

a first port, having at least two pins for transmitting power and several pins for transmitting data and connected by a cable to a main device port system, allowing for transmission of power and data; and

a second port, following a standard that is followed by said first port, except for having only pins for transmitting power, but no pins for transmission of data, allowing for transmission of additional power when connected with said main device port system.

16. A data and power transmitting peripheral connecting system according to claim 15, wherein said first and second ports have USB jacks.

17. A data and power transmitting peripheral connecting system according to claim 15, wherein said first and second ports have IEEE1394 jacks.
