Abstract: A waterproof electrical connector utilizing polyurethane bonded to electrical conductive pins, sleeves, polyurethane core, electrical cable conductor insulation, and cable jacket to form a water impenetrable molecular composition around the cable connection in combination with rubber to rubber isolators surrounding the separatable pin and sleeve connection. The connector is useable with or without coupling sleeves.

Abstract: A method and apparatus is disclosed for waterproofing electrical connectors for use in deep water and abusive environments such as that involving seismograph underwater exploration. The present invention combines the technology expressed in the referenced prior art with a method for sealing pin wiring connections and bonding the wiring sheath insulation to a pliable molded body surrounding a central core encompassing the connectors pins in a single injection molding operation. The process includes providing a length of special cable having one or more conductors with multiple sheaths for attachment to an underwater type cable connector having at least one sheath compatible with the injection molded body, the compatible sheath and a portion of its compatible outer jacket being integrally molded to form the connector's body.

Abstract: A molded protective body member for seismic cable hydrophone and geophone sensors and their cable splice connections from underwater obstructions and pay-out and retrieval apparatus. The body member is a one piece polymeric member having interior cavities, risers and apertures. When in use, the body member is folded longitudinally in half around the seismic cable at a hydrophone or geophone splice joint and secured in place with recessable molded straps having threaded fasteners passing through each of the body halves thus clamping the body to the cable. At least one interior diametrical cavity is provided consistent with the type seismic cable sensor used. With the sensor and its associated cable and connector positioned within the protective body member, tie wraps are threaded through apertures along and adjacent the longitudinal edges of each half thus closing the interior of the body member. Cavities are also provided internally for placing lead weights.

Abstract: An improved termination connector for seismic cable, the improvement including a reduced rigid length and improved flexibility by making connector to cable conductor splice connection within the bend restrictor, further reducing failure due to lateral stress through the use of a split collar and sleeve arrangement for connecting the connector's rotatable nut assembly to the connector body. The instant connector improves pin to cable makeup with improved pressure compensation splice connection process.

Abstract: Submersible cables that are placed in a body of fluid such as water or other fluids such as chemicals or sewage often require a takeoff to be added to the submersible cable wherein a window is cut in the exterior insulation of the submersible cable or parent trunk exposing interior wires or fiber optical cables or tubes and the like.
