  • Patent number: 4541684
    Abstract: An aircraft grounding receptacle comprising a connector portion and a tubular portion. The connector portion includes an external thread and a hexagonal portion. The tubular portion includes a reduced diameter portion and a hexagonal flange. Four slots separate the tubular portion into four segments and intersect the flange at locations spaced apart from four of the six points comprising the hexagonal shape of the flange. A bore extends through the body for receiving an aircraft grounding plug and includes reduced diameter portions for mating engagement with the terminal groove of the plug.

  • Patent number: 4525014
    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).

  • Patent number: 4407529
    Abstract: A self-locking coupling nut (14) includes a nut surrounding a first shell (12) for threaded engagement with a second shell (66) to secure the shells in mating engagement. A plurality of balls (52) mounted in the nut are initially engaged with a ball receiving surface (24) on the first shell, and upon threaded engagement between the nut and second ball are cammed outwardly into ball receiving grooves (32) to secure the nut against inadvertent disengagement from the second ball. Outward movement of the balls cams a spring (56) outwardly to provide visual and tactile proof of the locked condition of the self-locking coupling nut. Threaded engagement of the nut with the second shell also compresses a spring between a thrust ring (20) on the first shell and a retaining ring (44) on the nut.
