An improved electrical panel assembly of the type providing a plurality of receptacles for use with cable connectors and requiring that the connectors must be connected with their respective receptacles in a given order and disconnected therefrom in the reverse of that order. The panel assembly comprises a planar panel element having an opening therein for each receptacle and a receptacle mounting housing element behind each panel opening, constituting an integral, one-piece molding. Each panel opening is provided with a cover swingable between a closed position and an open position. The connectors and receptacles are of the known type having single contacts which lock together when the connector is mated with the receptacle and rotated a partial revolution. Polarizing devices are provided in association with each receptacle and each cable connector. Each panel opening, except the first, is provided with a locking mechanism of simplified construction which is shiftable between a normal locking position wherein it precludes opening of the cover of the next adjacent panel opening and a retracted position permitting opening of the cover of the next adjacent panel opening. The locking mechanism of each opening is shifted to its retracted position when the appropriate connector is inserted through the preceding opening and mated and locked with its receptacle. Each locking mechanism in retracted position precludes removal of the connector from the preceding opening. As a result of the simpler locking mechanism, the panel can be made smaller overall, with fewer parts and simpler assembly.
