Background

The cause of failure on an aircraft external power receptacle connector is the coupling method between the aircraft ground receptacle and the ground power plug. The physical engagement of the electrical contact pins on the aircraft fixed connector and the socket contacts on the ground supply free connector maintains the external power connector's coupling causing this failure. The sphincter or grabbing action of the high force socket contacts within the ground supply free connector causes premature excess wear on the pin contacts contained in the aircraft fixed connector. Additional failure is caused by the sheer weight of the ground supply free connector, which pulls down on the electrical interface causing arcing when the power is on. Replacement of either the aircraft fixed connector and/or the ground supply free connector is a significant loss to the airline and/or airport.  The MS90362-3 aircraft power saver receptacle shown above mates with the aircraft external power receptacle connector shown below.


Aircraft Ground Power Saver Connector

Solution

Our factory has devised an adapter or Aircraft Ground Saver Connector which essentially bears the brunt of the normal in use abuse described. This adapter requires no special provisions (such as mounting holes) for attachment to the external ground power interface, the user merely mates the adapter to the external ground power receptacle and tightens four screws which are an integral part of the Aircraft Ground Power Saver Connector assembly. Extensive testing has proven that the addition of the Aircraft Ground Power Saver Connector provides improved electrical performance to the mated external power receptacle and ground supply free plug connectors. To remove a worn out adapter, the described screws are loosened then the two ejector screws are tightened and the adapter can then be replaced.

By the addition of the Aircraft Ground Power Saver Connector, the existing external power connection is electrically enhanced. More importantly, the Aircraft Ground Power Saver Connector will be the source of any wear caused by arcing and/or repeated coupling and uncoupling of the ground supply free power plug to the fixed power receptacle. Also, the user friendliness of replacing (installing and removing) the Aircraft Ground Power Saver Connector significantly lower maintenance costs to both the airlines and airports.
