Abstract: Description of Driving Event:
Various times throughout 1960-1975, functional problems were encountered because a set of connectors were unmated or contacts in the connector were deformed as a result of misalignment during mating.
The unmated connector condition was the result of deviating from normal processing. Break of inspection sheets were added to applicable logbooks to alert test technicians and engineers of the unmated connectors. When the connector was remated, the condition was verified on the break of inspection sheet.
Deformed contacts were often the result of slightly bent pins or the misalignment of pin and socket at the time of mating. Tapered socket entry reduced this problem. Misalignment of replaceable contacts was sometimes caused by wire routing at the rear end of the connector. If inspectors had performed a visual examination of both connectors prior to mating, misalignment of contacts would have been greatly reduced.
Further information can also be obtained by contacting the Reliability and Quality Division of Loral Vought Systems at P.O. Box 650003, Dallas, TX, 75265-0003 or calling (214) 603-1000.
