  • Patent number: 11175352
    Abstract: The present disclosure describes various alternative embodiments of plug force testers, in particular devices well-suited for testing aircraft ground power connection plugs. The disclosed plug force testers provide a fixed, well-supported position for test pins on which a plug is inserted, which can be positioned to correspond to a height or orientation of the pins in an actual aircraft. Embodiments described also may include means for preventing excessive force application during testing.

  • Patent number: 10938171
    Abstract: A portable power distribution unit for safely distributing high wattage power supplied from mobile generators to lower power test adapter units and systems. Embodiments disclosed include a structurally rigid housing shaped to facilitate secure holding by an operator's foot, a 400 Hz power connector adapted for connection to a mobile power generator, a circuit breaker matched to the rating of the system to be powered and connections for conversion of the six-pin output from the mobile generator to a three or four-pin input for the system to be powered.

  • Patent number: 10044128
    Abstract: A modular, repairable aircraft ground power receptacle includes a base containing pin bases with outwardly opening sockets. Removable pins are secured in the sockets and a pin cover plate is placed there over with prong ends of pins extending through the pin cover plate for connection with a ground power plug. Damage pins may be removed and replaced without disconnecting aircraft power cables from the receptacle. Repair kits may include replacement pins and, optionally, replacement cover plates and related fasteners and tooling.

  • Patent number: 4857011
    Abstract: A connector is described, of the type which is attached to the outer end of a cable and used at an airport to supply power to aircraft on the ground, which facilitates installation and repair of the connector in the field. The connector includes a rubber housing 20 with contact-passing holes 24-29 at the front end and an opening 34 at the rear. The connector also includes a plastic tray 36 which holds the contacts 51-56 and the end portion of the cable where the wires 71-76 of the cable connect to the contacts. After connections are made at the tray, the tray is slid forwardly through the rear end of the housing deep into the housing, with the front of the contacts aligned with the holes at the front of the housing, and a grommet 86 is emplaced to seal the rear of the housing.
