Abstract: A fiber optic connector is disclosed in which the cable strength member termination comprises inner and outer sleeves surrounding the cable. One of the opposed surfaces of the sleeves is disposed at an angle which opens rearwardly. A clamping ring is disposed between the sleeves. The strength member of the cable is folded back between the angular surface and the clamping ring so that when aa rearward axial load is applied to the cable, the strength member will become more tightly clamped.

Abstract: An electrical contact for a coaxial cable (3) includes a tubular shell (17, 35) forming an outer contact element (19, 37) and an inner socket (13) or pin (31) type contact element having a pair of laterally spaced resilient fingers (49, 63) housed in a tubular insulator (15, 33). As the tubular insulator (15, 33) is inserted into the tubular shell (17, 35), wedge blocks (85, 107) extending laterally through slots (95, 113) in the walls of the insulator, compress the resilient fingers of the contact element against the center conductor of the cable. The cable shielding (7) is splayed back over a resilient sleeve (115) at one end of a bushing (21) which slides onto the end of the cable. This sleeve is split longitudinally and is resilient such that it may be compressed radially to insert it into the tubular shell (17, 35) where it expands to press the splayed back cable shielding into contact with the tubular shell.

Abstract: A connector for interconnecting the ends of two optical fiber cables to provide accurate alignment of the optical fibers free of stress from the mechanical linkage of the respective cables. The sheath at the adjoining end of each cable is split in two and separated to expose the optical fiber. The split ends of the sheath are inserted in separate diverging holes in a mounting ferrule while the exposed optical fiber is inserted in a central bore between the diverging holes. The sheath ends are anchored by cementing the ends in the holes. Only the very outer end of the exposed optical fiber is anchored by cement in the ferrule to fix the alignment of the fiber. The rest of the exposed fiber between the anchored outer end and the point at which the sheath is split is bowed slightly to relieve any tension on the fiber. The ends of the cables are joined by mounting the ferrules in a common connector body with the outer ends of the fibers held in abutting axial alignment.

Abstract: A cable terminal connector includes means for securing a terminus of a grounding or shielding conductor of a coaxial or non-coaxial type cable within a body of dielectric material. The junction of the grounding or shielding conductor with the dielectric material is characterized by means for distributing and lessening the intensities of mechanical or electrical stresses that may occur at the junction during use of the terminal connector in transmitting high DC voltage, low current power for electrostatic applications.

The ferrule also has a slotted frusto-conical surface to fit against the frusto-conical surface of the body. The slots form spring projections that are held in pressure contact with and in good electrical contact with the said body surface. The back-nut shoulder pushes the ferrule toward the body as the back-nut is threaded thereto. The back-nut has a flange behind which a gasket gland is retained. The clamping member is held in axial compression between the ferrule shoulder and the gasket gland.

Abstract: A cylindrical high temperature logging tool assembly supended from the shield of a coaxial cable for insertion into the interior of a well bore. To isolate the instruments contained within the interior of the cylindrical assembly from the fluids or steam within the well bore, and to facilitate assembly, the cylindrical oil tool comprises a plurality of axially aligned segments including a grease holding cavity at the end thereof wherein a quantity of non-conducting grease is packed and is compressed therein by the threadable engagement of the sections. Since most greases are generally incompressible, the threaded assembly provides a technique by which the grease pressure level within the housing can be achieved which are greater than the pressure head within the well bore. In this manner an integral structure is provided which can be deployed at various depths within the well bore and which furthermore provides selective arrangement of sections to arrange the requisite instrumentation for well bore logging.
