Abstract: A system for bypassing a signal tap that includes a pair of plug ports which are aligned with a pair of contact terminals that connect the conductors to the tap. The system generally comprises a pair of contact plugs adapted to be inserted into the plug ports and a jumper. Each plug includes a generally hollow body and a plunger. The hollow body is substantially open at a first end and terminates in a head surface, having an aperture therethrough, at a second end. Each plunger is moveable between a non-contact position and a contact position. The jumper includes at least two pins which are conductively interconnected and adapted to be inserted into the apertures to allow a signal flowing through the tap to flow through the jumper.

Abstract: A sealed F-connector, with a threaded section and a recessed section adjacent the threaded section, has a ring-shaped elastomeric sealing member formed within the recessed section and affixed to the surface of the recessed section. When a connector shell from a mating connector is screwed on, the sealing member deforms as the connector shell screws on over the sealing member, thereby lining at least a portion of the internal thread of the connector shell and at least a portion of the recessed section of the F-connector. The deformed sealing member thereby establishes a barrier to the penetration of moisture between the F-connector and the mating connector.

Abstract: In order to seal an electrical connector in a manner wherein mating of the connector components does not deteriorate environment sealing elements or require periodic maintenance, a GRAFOIL.RTM. type end seal is arranged to be abutted by a leading edge portion of one of a male plug member and a female receptacle members in a manner which establishes the sole hermetic seal for the connector.

Abstract: A lamp socket in which the socket body is formed of two symmetrical halves connected together a dovetail joint; a rubber packing ring is mounted around the bottom lamp hole of the socket body to prohibit water from passing to the inside of the socket body after the installation of the lamp bulb; a movable metal contact plate is suspending inside the socket body and adapted for connecting the tip contact of the lamp bulb to the positive metal contact plate upon the insertion of the lamp bulb in the socket body; a spring is mounted inside the socket body to force the movable metal contact plate downwardly away from the positive metal contact plate after the removal of the lamp bulb.

Abstract: A lamp socket in which a rubber water sealing cushion is mounted in a top recess at the center of the transversely grooved top wall of the socket body and covered around the electric wire to protect the positive metal contact plate against outside water, a rubber socket is mounted inside the socket body and covered around the positive metal contact plate, having an outward flange which is pressed on the base top of the lamp bulb and circularly covered over the tip contact thereof, and a metal strip transversely suspending on the inside and forced by the tip contact of the lamp bulb into contact with the positive metal contact plate.

Abstract: A waterproof packing is axially compressed between a pair of female and male connectors in intimate contact therewith to form a liquid-tight seal between the two connectors. An axial thickness T1 of a radially outward portion of a compression portion of the packing which can be compressed between the two connectors is smaller than a thickness T2 of a radially inward portion thereof. With this construction, the radially-outward bulging or deformation, caused by the axial compressive deformation, proceeds progressively from the radially inward portion, so that the radially-outward bulging or deformation can be suppressed to a low level.

Abstract: An end connector for a coaxial cable has a rotatable nut with an internal thread configured and dimensioned to coact in threaded engagement with a complimentary external thread on a system component. A circular seal element is contained within and axially fixed with respect to the nut. The seal element is deformable into a configuration lining at least a portion of the internal thread to thereby establish a barrier to the penetration of moisture between the interengaged internal and external threads.

Abstract: An improved igniter and cable connector assembly for turbine engines. An igniter mounting adapter is secured to the engine. The igniter slides into a hole through the adapter and is retained by an enlarged head on the igniter. An annular seal is positioned around a high voltage terminal on the igniter head and a terminal on the cable connector is positioned against the igniter terminal. The cable connector is secured to the adapter, for example, by either a clamp assembly or a coupling nut or a quick release connector.

Abstract: A plug-receptacle type electrical connector in combination with a thin, cular, elastomeric membrane joining a plurality of cylindrical elastomeric embossments formed as an integral part thereof. Each embossment further has conical ends at each extremity and an outside diameter slightly larger than the receptacle socket cavity it will contact. Each embossment also has a longitudinal through-hole of inside diameter (ID) slightly smaller than the electrical connector plug pin it is intended to fit over. The membrane is coated with a dielectric grease and slipped over the plug pins. Connector clamping force produce hydrostatic forces, first on each embossment which causes water remaining between the pin and the embossment ID and then pin-to-pin to be broken into a discontinuous series of microspheres. The resulting discontinuity produces full electrical isolation for the assembled pins and sockets and pin-to-pin for the mated connector. Total refurbishment of a connector may thus be accomplished in situ.

Abstract: Mateable receptacle and plug assemblies comprising a cable connector for use in a nuclear environment. The receptacle assembly and the plug assembly comprise mateable metallic shells, each surrounding one or more cable ends terminating in contacts. The contacts of the receptacle assembly and the plug assembly are equal in number and mateable. In each of the receptacle assembly and the plug assembly, the space between the shell and the cable ends and their contacts is filled with one or more heat, steam and radiation resistant insulative elastomeric compounds and/or epoxy compounds to prevent hosing of steam and moisture through the cables. The inside surfaces of the shells are uniquely configured to enhance bonding thereof to the insulative compounds, providing baffles creating pressure drops should the bond fail. O-rings are mounted on the plug assembly shell which cooperate with the receptacle assembly shell to form compression and butt seals to prevent leakage through the shell faces.
