Abstract
There is provided a plug which includes electrodes that transmit direct-current power and an electrode cover that covers the electrodes. The electrode cover includes a lock detection unit that electrically detects that the electrode cover is locked.
Claims7
A plug comprising:
- electrodes that transmit direct-current power;
- an electrode cover that covers the electrodes,
- wherein the electrode cover includes a lock detection unit that electrically detects that the electrode cover is locked to a plug receptacle including a lock mechanism after the electrode cover is completely inserted into the plug receptacle;
- and
- a detection line that electrically detects that the electrode cover is locked to the plug receptacle after the electrode cover is completely inserted into the plug receptacle,
- wherein the lock detection unit electrically detects that locking is performed with the detection line short-circuited, when the electrode cover is locked to the plug receptacle after the electrode cover is inserted into the plug receptacle, and
- wherein the electrode cover includes on an outer circumferential surface a lock groove for locking with the plug receptacle in a bayonet type, and the lock groove includes at a terminating portion a lock detection electrode to electrically detect locking with the plug receptacle.
