Locking Device for the Charging Plug of an Electric Vehicle Charging System

A locking device for an electric vehicle charging plug using the J1772 standards. The main component of the device consists of an outer shell and an inner shell. In the open position, the inner shell will slide along the designated tracks away from the outer shell, allowing the electrical plug to be insert into the inner shell. In the close position, the outer shell enclosure is moved over the locking hook and prevents plug from being removed from the inner shell. The inner shell has a lock anchor that passes through the outer shell. A user can then install a pad lock at the end through this anchor to prevent the outer shell from sliding back into the open position. The reversal of the above process allows the plug to be removed.
