Abstract: A modular contact assembly including first and second members at opposed ends such as a wire barrel member (20) or a contact member (50,100) having either a socket contact section (62) or a pin contact section (108) at a mating end, and optionally an intermediate member (80) interposable between the first and second members. Assembly faces (30,84) of one of the members (20) and intermediate member (80) each may include a small diameter bore (28,82) thereinto, and mounting faces (54,88) of the other of the members and intermediate member each may include a cylindrical embossment (56,86) extending therefrom having a diameter slightly larger than that of the small diameter bores, enabling force fittable insertion thereinto during contact assembly. The wire barrel member (20) is usable with either a pin contact member (100) or a socket contact member (50), and the intermediate member (80) enables fabrication of an elongate socket contact assembly (10) or pin contact assembly if desired.

Abstract: A high-voltage cable connection (10) includes a standard terminal (12) which fits into a female receptacle in apower supply or x-ray tube to make an electrical connection. A cable (14) is routed through a proximal end (30) of the terminal (12). A clamp (18) secures a jacket (42) of the cable (14) to a cap (16) at the prominal end (30). A boot (20) envelops the cable (14) at a point where the cable (14) enters the terminal (12). A collar (22) which is split into halves or segments (22A, 22B) fits conformably about a boundary formed between the proximal end (30) of the terminal (12) and the boot (20). A ring (24) fits about the collar (22) to hold the segments (22A, 22B) together. A nut (26) having an external thread portion fits over the collar (22) and the ring (24), the nut (26) being rotatable about the collar (22) and the ring (24) and mating with internal threads which form a part of the female receptacle in the power supply or the x-ray tube.

Abstract: A partially stripped reinforced electric signal cable and processes for its manufacture and termination by use of an easily-removable hardenable reinforcing material which allows maintenance of conductor alignment and manipulation during termination of the cable with removal of the reinforcing material during the termination process in order to facilitate completion of the termination.

Abstract: A cable and termination for high voltage and high frequency current carrying applications includes an inner conductor having a sheath of braided metallic wire and a cylindrical core of flexible material extending within the sheath and supporting the sheath to prevent reduction in diameter of the sheath in response to tensile forces applied to the cable. The core includes one or more wire filaments connected to bear a portion of tensile forces applied to the cable. The inner conductor is encased in an outer insulation assembly which includes a conducting layer, spaced from the sheath and connected for ground return. The cable includes a termination assembly having a socket, connected to the sheath and wire filaments, for receiving an inner conductor of a complementary termination assembly.

Abstract: A corrona test set has at least a reactor and power separation filter placed in an oil-filled conductive tank of a conductive material such as sheet steel. The exciter optionally may also be placed in the same tank enclosure which is of much smaller size than the equivalent voltage rating rest set in air. High voltage taken from the circuit passes out of the tank through high voltage bushings. A preferred form of bushing is a quick coupling cable receiving device having an insulator extending into the tank and a frustoconical metallic extension extending away from the tank with a tubular internal wall connected to these respective parts at opposite ends to form a further oil-filled compartment separate from the tank.

Abstract: A fiber optic connector (1) for an optical fiber cable (2), comprising; a strain relief (3) encircling the cable (2), a housing (4), and a fixture (5) attached to the strain relief (3), the fixture (5) interlocking with the housing (4) at a stationary position angularly pointing the strain relief (3) and the cable (2) relative to the housing (4).

Abstract: A cable termination assembly for terminating a high voltage current-carrying conductor includes an outer porcelain housing and an inner polymeric liner of low durometer, cast in the housing before insertion of the cable. The liner is bonded to the housing wall to prevent air voids. A metal base member amy be employed and may include an upstanding shielding collar extending part way into the housing and being joined thereto by the cast liner.

Abstract: A plug-in type pothead includes specially designed seal sleeves formed from a heat shrinkable polymer. One end of the sleeve has an annular collar about it which, when snugly fitted within the motor lead entry hole of the terminal block, forms a watertight seal between the terminal block and the sleeve. The other end of each of the sleeves is heat shrunk about its respective motor lead to form a watertight seal between the sleeve and the lead. In addition, a gasket between the connecting face of the terminal block and the connecting face of the pothead provides a watertight seal between the pothead and the terminal block. The result is a completely watertight connecting system, extending from the pothead through the terminal block to the motor leads.

Abstract: A cable termination connector assembly for physically receiving and securely retaining the bared end of a current carrying center conductor of a high voltage power cable and for making an external electrical connection to the center conductor includes a multi-barrel connector for use with many different sizes of high voltage power cables. A plurality of elongated, generally axially extending apertures are formed in the connector for receiving the wire strands of a segmented or nonsegmented center conductor of a high voltage power cable. In a specific embodiment, the apertures are canted or inclined with respect to the longitudinal axis of the center conductor and the multi-barrel connector to minimize the length of cable insulation that is cut away or stripped back and thereby increase the dielectric strength or reduce the size of the termination assembly and facilitate insertion of the wire strands.

Abstract: A terminal connector for high-current electrical cables includes an electrically-insulating casing of resin-impregnated glass fibers surrounding an end portion of an electrical cable, and a conductive member connected to the end portion of the cable and extending through an axial end of the casing. The casing has an inner collar which cooperates with two movable nuts to adjustably mount the conductive member in an axial end of the casing, and an outer collar to secure the casing to a base plate. The conductive member is formed with an annular groove which receives a resilient sealing ring. The sealing ring slides along an inner circumferential wall of the casing and seals the interior of the casing from its exterior throughout the entire adjustment range of the conductive member. A protective electrode attenuates electrical fields in this axial end, and an electrically-insulating housing having a fluid medium contained in its interior surrounds the casing.

Abstract: A cable termination connector assembly for physically receiving and securely retaining the bared end of a current carrying center conductor of a high voltage power cable and for making an external electrical connection to the center conductor includes a multi-barrel connector for use with many different sizes of high voltage power cables. In a specific embodiment, four, elongated, axially extending apertures are formed in the connector for receiving the wire strands of a segmented or nonsegmented center conductor of a high voltage power cable. For smaller power cables, only one or two of the four apertures may be used; for larger power cables, three or four of the apertures may be used.

Abstract: A flexible cable termination for high voltage cables such as used in x-ray apparatus, which termination has an outside diameter only slightly larger than the diameter of the cable, and has flexibility provided by encasing the cable wires in a flexible sheath which provides the cable termination assembly with the ability to be bent to relatively small curvatures, and further includes means for attaching the cable grounding braid to an encircling grounding terminal.
