91-6739 is a high-current anti-spark quick-connect power connector assembly categorized under aviation maintenance tools and ground support equipment (GSE), purpose-built for safe and stable power transmission between airport ground power units and narrow-body commercial aircraft during engine-off long-term heavy maintenance procedures. This dedicated connector eliminates arcing, loose contact and overheating risks that often occur during high-current 400Hz AC power supply operations in open-air apron environments, fully meeting the strict power connection safety requirements of global airline MRO facilities.

Manufactured from high-conductivity oxygen-free copper with precision nickel-gold plating and reinforced PPS insulating housing, 91-6739 maintains stable 400A continuous current transmission performance under frequent plug-and-unplug cycles, fully complying with FAA and EASA mandatory aviation GSE safety specifications. Its foolproof anti-misinsertion locking structure cuts ground power connection setup time by more than 50%, significantly improving aircraft maintenance pre-work efficiency.
