Abstract

[Object] To provide a common plug for AC/DC which can easily prevent erroneous insertion into a plug receptacle.
[Solution] Provided is a common plug for AC/DC including at least one pair of connection terminals. At least one connection terminal of the at least one pair of connection terminals is able to rotate around an axis of an insertion direction into a socket so as to have a first state in a case where the connection terminal is inserted into a socket for supplying AC power and a second state in a case where the connection terminal is inserted into a socket for supplying DC power, the second state being different from the first state.

First claim

The invention claimed is:

1. A plug for AC/DC comprising:
at least one pair of connection terminals,
wherein at least one connection terminal of the at least one pair of connection terminals is configured to rotate around an insertion direction into a socket so as to have a first state in a case where the connection terminal is inserted into a socket for supplying AC power and a second state in a case where the connection terminal is inserted into a socket for supplying DC power, the second state being different from the first state.

2. The plug for AC/DC according to claim 1 ,
wherein the at least one pair of connection terminals changes an angle with respect to a direction orthogonal to the insertion direction into the plug receptacle between the first state and the second state.

3. The plug for AC/DC according to claim 1 ,
wherein the at least one pair of connection terminals is able to rotate within a restricted angular range.

4. The plug for AC/DC according to claim 1 ,
wherein the axis of the at least one connection terminal is provided on the connection terminal.

5. The plug for AC/DC according to claim 1 ,
wherein the axis of the at least one connection terminal is provided while being displaced from the connection terminal.

6. The plug for AC/DC according to claim 1 , comprising:
a signal output unit configured to output a switching signal when the at least one pair of connection terminals are put into the second state.

7. The plug for AC/DC according to claim 1 ,
wherein, when one connection terminal out of the at least one pair of connection terminals rotates, the other connection terminal is able to rotate in the same direction as the rotation direction of the one connection terminal.

8. The plug for AC/DC according to claim 1 ,
wherein, when one connection terminal out of the at least one pair of connection terminals rotates, the other connection terminal is able to rotate in an opposite direction from the rotation direction of the one connection terminal.

9. Equipment for AC/DC that operates with power received by the plug for AC/DC according to claim 1 .

10. The equipment for AC/DC according to claim 9 , comprising:
a signal output unit configured to output a switching signal when the at least one pair of connection terminals are put into the second state.

11. The equipment for AC/DC according to claim 10 , further comprising:
a power conversion control unit configured to change conversion efficiency of power between a case where DC power is received and a case where AC power is received, according to presence or absence of the switching signal.

12. The equipment for AC/DC according to claim 9 , further comprising:
a diode bridge configured to rectify AC,
wherein, when DC power is received, an anode of the diode bridge is electrically connected to a connection terminal which becomes a negative side out of the pair of connection terminals, and a cathode of the diode bridge is electrically connected to a connection terminal which becomes a positive side out of the pair of connection terminals.
