Watertight low-cost electrical connector
Fabrication is described of waterproof electrical connector assembly for use with Teflon jacketed cables and constructed so that assembly will remain sealed under extreme environmental conditions. Conditions are specified as: pressure from vacuum to atmospheric; temperature from 280 K to 450 K; exposure to saturated steam; and steam suddenly introduced into vacuum.

Electromagnetic connector
Connector pair consists of two iron cores brought together a short distance from each other. Each core is wound with insulated wire. Ac signal is connected through the pair across the gap by magnetic induction. Device can be used underwater or in flammable atmosphere.

Flammability control for electrical cables and connectors
Technique of covering fire-hazardous sections of electrical wiring with fireproof materials prevents fires from spreading in oxygen-enriched atmospheres and eliminates use of heavy metal enclosures. Materials used to cover potting on connectors and ground terminals are made from Teflon-coated Beta cloth and Fluorel, a nonflammable fully-saturated polymer.

RF shielded connectors
Gap, where cable joins connector housing, is shielded effectively by composite RF shielding made from suitable potting resin material (fumed silica, thixotropic prepolymer composition), conductive coating (silver-filled, flexible, polyurethane resin), and protective jacket (wax coated housing formed around another wax form having contours shaped to match configuration).

Investigation of problems associated with solid encapsulation of high voltage electronic assemblies; also Reynolds connector study
Electric breakdown prevention in vacuum and encapsulation of high voltage electronic circuits was studied. The lap shear method was used to measure adhesive strengths. The permeation constants of air at ambient room temperature through four different space-grade encapsulants was measured. Order of magnitude was calculated for the time that air bubble pressures drop to the corona region. High voltage connectors with L-type cable attached were tested in a vacuum system at various pressures. The cable system was shown to suppress catastrophic breakdown when filled with and surrounded by gas in the corona region of pressures, but did not prove to be completely noise free.

Lines, connectors, joints, and fittings
The structural reliability of lines, connectors, joints, and fittings used in liquid and gaseous O2 systems was examined. Overstress and high velocity flow of gaseous O2 as they affect system failure are also examined. Special attention was given to efforts to determine factors for designing a reliable O2 transport system for operation at all possible pressures.

A separable fluid connector system effectiveness evaluation technique
An analytical technique is presented for evaluating the relationship among existing numerous separable fluid connector designs to find that configuration which is best (optimal). The data utilized in this research was acquired from approximately 900 flanges designed for six sub-systems of the S-1B stage of the Saturn 1B Space Vehicle. The method is general enough to be useful in optimizing design and systematizing decision-making in a variety of related technical fields.

Capacitive connectors for digital-data lines
Proposed connector consisting of twin metal films separated by thin layers of insulating material transmits digital pulses capacitively. There is no direct contact between metal films; therefore, there is no ohmic contact drop and no wear when connections are changed. Since metal films are sealed in insulating material, there is no corrosion from exposure to atmosphere.
