Abstract:
An electrical plug and receptacle can be connected and disconnected in the presence of explosive gas without causing a spark and possible explosion. Power is disconnected from the receptacle unless the plug is fully inserted and locked into position in the receptacle. A sensor detects when the plug is fully inserted and locked. The sensor energizes a relay which allows power to flow to the receptacle and the connected plug. The relay is encapsulated in epoxy or isolated in a Restricted Breathing enclosure to keep explosive gas away from the sparking relay contacts. To remove the plug from the receptacle, it must first be unlocked. The sensor detects the motion of unlocking the plug and releases the relay to disconnect power from the plug and receptacle so that no spark is created when the plug is removed from the receptacle. Ordinary NEMA plugs and receptacles can be used in Zone 2 and Class I Division 2 hazardous locations.

Claim (Index 9):
The electrical connector of  claim 7  in which the sensor arrangement comprises a magnet on one of the plug and receptacle and a magnet sensor on the other of the plug and receptacle.
