Abstract

A first embodiment of an aircraft grounding receptacle (10) comprises a connector portion and a tubular portion (18). The connector portion (12) includes an external thread (14) and a hexagonal portion (16). The tubular portion includes a reduced diameter portion (40) and a hexagonal flange (24). Four slots (34) separate the tubular portion (18) into four tines (26,28,30,32) and intersect the flange (24) at locations spaced apart from four of the six points comprising the hexagonal shape of the flange. A bore (38) extends through the body for receiving an aircraft grounding plug (52) and includes reduced diameter portions (40,41) for mating engagement with the terminal groove (54) of the plug. A second embodiment of the aircraft grounding receptacle (60) comprises a plug receiving portion (62) and a collet portion (64). The plug receiving portion includes a flange (66) adapted for engagement with the interior surface (82) of an aircraft panel (80) and having a surface (70) sloping inwardly toward the collet portion (64). An extension (72) projects through an aperture (128) in the aircraft panel (80) and has a hexagonal internal bore (84). The collet portion (64) includes a plurality of segments adapted to matingly receive an aircraft gounding plug therein. A washer (120) receives the receptacle therethrough and includes a dimple (122) which engages the sloping surface (70) of the flange (66). The dimple (122) of the washer (120) is trapped between the sloping surface (70) of the flange (66) and a housing (110) which surrounds the collet portion (64) of the receptacle (60). The washer (120) is secured to the aircraft receptacle (60) by a plurality of rivets (126).
