<P>PROBLEM TO BE SOLVED: To provide a power supply plug locking device which prevents a power supply plug connected to an inlet from being improperly removed without authorization and simplifies the operation for inserting or removing the power supply plug into or from the inlet. <P>SOLUTION: When a power supply plug 10 is connected with an inlet 5, the power supply plug 10 is locked into the inlet 5 by a locking device 40 provided at the inlet 5. This locking does not allow a third person to improperly remove the power supply plug 10. When an engaging pawl 21 of the power supply plug 10 is guided to a locking position in a recessed portion 43 by a biasing spring 24, a lock bar 45 engages with the engaging pawl 21 to get the locking device 40 into the locking state. Further, when the lock bar 45 is retracted and the engagement between the lock bar 45 and the engaging pawl 21 is released, the locking device 40 gets into the unlocked state. <P>COPYRIGHT: (C)2012,JPO&INPIT |
