Abstract: A class of electrical connectors are described along with methods of manufacturing the same. In one example embodiment, a method of assembling a connector includes extending a twisted pair through a slot in a seal plate; untwisting the twisted pair along a first distance; inserting first and second conductors of the twisted pair through first and second through holes of a seal carrier; coupling first and second electrical terminals to the first and second conductors; re-twisting the twisted pair along a portion of the first distance by rotating the seal carrier; and inserting the seal carrier into the slot of the seal plate.

Abstract: There is provided an electric cable insert for removably electrically connecting a cable having multiple conductors to a mating receptacle wherein the number and configuration of the cable conductors may be different from those of the sockets of the mating receptacle. The insert includes a housing open on one end to an internal cavity and having a plurality of orifices in the other end. The cable conductors connect to one side of a circuit card within the housing which conductively transitions from the number and configuration of the cable conductors to the number and configuration of the sockets of the mating receptacle. Receptacle pins extend from the opposite side of the circuit card through respective orifices in the housing for connecting to respective sockets in the mating receptacle. A compressed sealing gland disposed within the housing adjacent the circuit card provides the insert with an energized compression seal from the environment.

Abstract: A conductive rope-like lead-in cable connects a seismic streamer to a towing vessel. The lead-in cable comprises a first electrical conductor at the center core of the cable for carrying a first polarity of power to the streamer for providing tensile strength to the load-in cable. A first layer of insulation surrounds the first electrical conductor. A second electrical conductor for a second polarity of power to the streamer surrounds the first layer of insulation. A second layer of insulation surrounds the second electrical conductor. A layer of seismic data conductors surrounds the second layer of insulation. A third layer of insulation surrounds the layer of seismic data conductors. A metallic protective layer surrounds the third layer of insulation. Steel is effectively and efficiently used both to provide tensile strength and for electrical power conduction.

Abstract: A fiber optic transmission line is passed uninterrupted through a hermetically sealed dielectric pressure barrier. This is accomplished by fusing glass or casting a resin about hollow upstanding sleeves within the bore of a connector housing. The glass forms a strong hermetically sealed barrier caused by strong compressive forces resulting from the different coefficients of thermal expansion between the metal bore walls and glass matrix. A fiber optic core is passed through a hollow sleeve and sealed to an aperture in a contact pin which is hermetically sealed to the end of the sleeve. The end of the pin is polished to provide an abutment joint with a corresponding contact surface on an associated connector. In the case of a resin matrix, the resin may be cast about the sleeves within the housing bore. During hardening, the resin will bond to the sleeves and walls of the bore to form a strong hermetically sealed pressure barrier.
