Miniaturized High-Altitude, High-Temperature Connectors

A new series of miniaturized multicontact connectors for high-temperature high-altitude conditions has been developed. The degree of performance achieved represents a considerable advance in the connector art. Both nonshielded and shielded contact designs have been incorporated in these connectors. Three exceptional features under extreme environmental conditions characterize these connectors: at altitudes in the order of 70,000 feet and temperatures of -- 85°F., the connectors permit operation at 500 volts ac 60 and 400 cps and withstand test voltages of 1000 volts ac 60 cps. Connectors are moisture resistant continuously during a ninety day humidity exposure maintaining a minimum insulation resistance of 200 megohms. Operating temperatures for these connectors are +500°F. to --85°F. Design features and test data under the environmental conditions are presented.
