Abstract

An electronic device includes a power receiver that manages power transmitted from an outside; and a receptacle including a plurality of first basic connection terminals based on a first Universal Serial Bus (USB) interface and a plurality of first expansion connection terminals based on a second USB interface, wherein the first expansion connection terminals includes one or more first power supply terminals that transmit power received through a cable device connected with the receptacle to the power receiver.

Claims

1. An electronic device comprising:

a power receiver that manages power transmitted from outside the electronic device; and

a receptacle including a plurality of first basic connection terminals based on a first Universal Serial Bus (USB) interface and a plurality of first expansion connection terminals based on a second USB interface, wherein the first expansion connection terminals include one or more first power supply terminals that transmit power received through a cable device connected with the receptacle to the power receiver.

2. The electronic device of claim 1, wherein the receptacle includes one or more control signal terminals that transmit a control signal for determining whether to supply power.

3. The electronic device of claim 2, further comprising a control signal generator that generates the control signal for determining whether to supply the power and is connected with the one or more control signal terminals.

4. The electronic device of claim 3, wherein the receptacle includes the control signal generator.

5. The electronic device of claim 2, wherein the cable device includes a first plug mounted to the receptacle to be connected with the plurality of first basic connection terminals and the plurality of first expansion connection terminals.

6. The electronic device of claim 5, wherein the first plug includes a plurality of second basic connection terminals and a plurality of second expansion connection terminals connected with the plurality of first basic connection terminals and the plurality of first expansion connection terminals, respectively.

7. The electronic device of claim 5, wherein the first plug includes one or more second power supply terminals connected to the one or more first power supply terminals, and a switching circuit that selectively outputs power to the one or more second power supply terminals based on the control signal.

8. The electronic device of claim 7, wherein the switching circuit includes a power semiconductor device including a source terminal connected with a terminal that receives power, a drain terminal connected with a terminal that outputs power, and a gate terminal connected with a terminal that receives the control signal.

9. The electronic device of claim 5, wherein the cable device includes a second plug connected to a receptacle of a power supply electronic device that supplies the power, and the receptacle of the power supply electronic device and the second plug include a plurality of connection terminals based on the second USB interface.

10. The electronic device of claim 5, wherein the first plug connected with the receptacle includes a protrusion, and the receptacle includes a protrusion accommodation unit that accommodates the protrusion.

15. The cable device of claim 1, wherein the first plug includes a protrusion connected with a protrusion accommodation unit included in the receptacle.

11. A cable device comprising:

a first plug including a plurality of first basic connection terminals based on a first USB interface and a plurality of first expansion connection terminals based on a second USB interface; and

a second plug including a plurality of connection terminals based on the second USB interface,

wherein the first expansion connection terminals include one or more power supply terminals connected with a receptacle included in an electronic device that receives power, to transmit power supplied through the second plug to the receptacle.

12. The cable device of claim 11, wherein the first expansion connection terminals include one or more control signal terminals that transmit a control signal for determining whether to supply power provided from the receptacle.

13. The cable device of claim 12, wherein the first plug includes a switching circuit that selectively outputs power to the one or more power supply terminals based on the control signal.

14. The cable device of claim 13, wherein the switching circuit includes a power semiconductor device including a source terminal connected with a terminal that receives power, a drain terminal connected with a terminal that outputs power, and a gate terminal connected with the control signal terminal.

16. A receptacle device comprising:

a plurality of first basic connection terminals based on a first USB interface; and

a plurality of first expansion connection terminals based on a second USB interface,

wherein the first expansion connection terminals include one or more first power supply terminals that transmit power received through a cable device connected with a receptacle to a power receiver included in an electronic device.

17. The receptacle device of claim 16, wherein the receptacle includes one or more control signal terminals that transmit a control signal for determining whether to supply power.

18. The receptacle device of claim 17, wherein the receptacle includes a control signal generator that generates the control signal and provides the generated control signal to the one or more control signal terminals.

19. The receptacle device of claim 17, wherein the one or more control signal terminals transmit the control signal to a switching circuit included in a plug connected with the receptacle.

20. The receptacle device of claim 16, further comprising a protrusion accommodation unit that accommodates a protrusion formed on a plug connected with the receptacle.
