ABSTRACT:
An electrical panel assembly providing a plurality of receptacles for use with cable connectors. 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 with respect thereto. The panel assembly comprises a front panel element with from two to five receptacles arranged in a side-by-side row therebehind. The front panel element has an opening therein for each receptacle through which a cable connector can extend for mating with the receptacle. Polarizing devices are provided in association with each receptacle and each cable connector to assure that each cable connector can be mated only with its respective receptacle. Each panel opening, except the first, is provided with a locking mechansim shiftable between a normal locking position wherein it blocks entrance of a connector into its respective panel element opening and a retracted position permitting entrance of a connector into its respective panel opening. The locking mechanism for 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 this, the connectors must be connected to their respective receptacles in a given order and disconnected therefrom in the reverse of that order.
