摘要

The procedures are described for modifying the electrical circuitry within the CF1764 pullout cable are described. The altered circuitry provides resolution of a specific electrical incompatibility between this cable and certain F-111aircraft. The circuitry modification was achieved by removing and replacing a pin in SA1445-1connector and by also installing a printed circuit jumper across the front surface of the connector insert. Since sufficient CF1764cable assemblies were not available for this evaluation,ten SA1445-1connectors were modified and tested to determine the adequacy of the altered interconnections. The test samples were subjected to temperature shock,high humidity,mechanical shock,vibration,and mating and unmating tests. Dc resistance,insulation resistance,and high potential were used to monitor the environmental stability of the assemblies. All of the modified samples performed successfully after the exposures. Two CF1764cables from stockpile were also modified and when tested under a simulated in-use operation,they performed the required drop options very successfully. (ERA citation 04:037324)
