ABSTRACT:
An interlock arrangement is disclosed for a unitary molded enclosure for electrical terminals such as for the terminals for a dead-front electrical plug. The enclosure is formed of electrically insulating material and has an interior chamber for housing the terminals and additionally has at least one moveable wall portion connected to the remainder of the enclosure by an integral web hinge. The moveable wall portion pivots on the hinge to an open position which provides access to the interior chamber of the enclosure. A number of interengaging locking members are integrally formed with the moveable wall and the remainder of the enclosure and engage one another when the moveable wall portion is closed to relieve stress on the hinge when assembling and using the enclosure and to provide safety even if the web hinge is weakened or fails. The unitary molded enclosure may have two such moveable walls, each with its own web hinge and interengaging locking members.
