ABSTRACT:
An electrical socket with locking protective doors comprises an upper cover with first and second upper ports. A bottom case couples with the upper cover and has socket terminals. A middle frame may comprise mounting brackets. Adjustable, lockable large and small protective doors are between the upper cover and the middle frame. A lock mounting guide plate coupled to the middle frame comprises large and small guide plate ports corresponding to the upper ports. Large and small protective doors are located on the lock mounting guide plate, and the small protective door is located between the large protective door and the lock mounting guide plate. The upper ports and the guide plate ports correspond to and vertically align with the socket terminals. When the protective door is in a first position, it prevents an object from passing to the guide plate ports. When the protective door is in a second position, it allows plug pins to access to the guide plate ports.
