CONNECTORS, ELECTRICAL, CIRCULAR, CRYOGEN ENVIRONMENT RESISTING, SPECIFICATION FOR
Organization:

Year: 1979
Abstract: This specification establishes the criteria for a family of circular miniature electrical connectors intended for use in cryogenic environments on both man-rated and unmanned space vehicles. These connectors shall not be used within the crew compartment of the space vehicle. The tank mounted receptacles shall be pin-to-pin and hermetically sealed. The mating characteristics, dimensions, and insert arrangements shall be in accordance with Specification MIL-C-83723B, Series 3. The external side of the bulkhead feedthrough receptacle and the weld mount receptacle, shall mate with an environmental plug capable of continuous operation within the temperature limits as transmitted when mated to -receptacles that have their internal portion exposed to temperatures down to -269ºC (-452ºF). The internal side of the bulkhead feed-through receptacle shall mate with a non-environmental plug also capable of operating at a temperature down to -269ºC (-452ºF).Intended Use: Intended use (all classes). Class E connectors. Class E connectors are intended for use in environment resisting applications external to the cryogenic tanks that require electric conductivity of the shells. Connector backshells must be installed to meet the specified moisture sealing requirements. Continuity is provided across the mated connectors from the backshell area on the plug to the mounting flange on the receptacle. Class H receptacles. Class H receptacles are intended for use in applications where the internal side of the receptacle will be immersed in the cryogenic fluids specified in 1.1 and where pressure integrity must be maintained for the pressures specified in 3.6.8. The external side of the receptacle will be subjected to the conditions described in 1.1. Class I connectors. Class I connectors are intended for use mated to the internal side of the class H receptacle and immersed in the cryogenic fluids specified in 1.1
