Abstract:
A method for electrically conductively connecting the electrical conductors (3, 4) of two high voltage cables (1, 2) is provided. The conductors (3, 4) are exposed at their ends by removing the respective casing and they are then inserted from different sides into a pipe piece (5) in such a way that they rest against each other with their end faces extending perpendicular to their axis and level with the central throughholes. The conductors (3, 4) are then secured by means of the securing screws (6) in the pipe piece 5 and bores extending in radial direction are made through the throughholes into which the two conductors (3, 4) project in the area of their end faces. Finally, the contact screws of an electrically well conductive metal are screwed into the central throughholes and further into the bores.
Abstract:
An improved electric wire connector includes a hollow tubular fitting element and a hollow tubular plug element inserted into a front end of the fitting element. The plug element has an annular curved rim which may press against a front edge of the fitting element when the plug element is inserted into the fitting element. The fitting element is further provided with external threads at a middle section thereof for enabling the fitting element to be screwably inserted into a screw hole of a conductive element. An electric wire has the plastic skin at a front end portion thereof stripped to expose the wire strands. The electric wire is inserted via a rear end of the fitting element with the stripped skin pressing against a rear end of the plug element so that the wire strands pass through the fitting element and the plug element to expose on the outside. The wire strands are bent inwardly to lie against the curved rim so that it may be held firmly between the curved rim of the plug element and the fitting element after the fitting element is fitted together with the plug element into the conductive hole, thereby preventing the electric wire from possible damage.
Abstract:
An electrical connector includes a cage which defines a wire receiving area aligned with a wire insertion axis, an elongated slot oriented obliquely with respect to the wire insertion axis, a clamp guided by the slot for movement toward and away from the wire receiving area, and a clamp screw rotatably mounted in the cage to move the clamp toward and away from the wire receiving area. The cage includes side walls and top walls, and the top walls are mechanically interlocked to resist separation. The clamp defines elongated ribs that engage the elongated slots, and the elongated ribs are configured to resist rotation of the clamp in the cage. The clamp is configured such that a portion of the clamp cantilevers beyond the free end of the screw when the screw is rotated to bring the clamp closely adjacent the contact surface. The screw is held in place in the cage by transverse slots defined by wings of the cage. These transverse slots intersect the elongated guide slots that receive the ribs of the clamp.
Abstract:
A tubular anode includes an electrical connector formed of a diagonally split two-part generally cylindrical slug. The diagonal slit provides an elliptical wedge interface between the two parts and a jack screw is threaded in one part and extends through an enlarged hole in the other. Tightening the jack screw within the tube causes the two parts to offset and wedge against the inside of the tube. The two parts include an aligned slot which intersects the major axis of the elliptical interface and a lead wire or cable is electrically secured to one of the parts within its slot. The slot is configured to press the lead or cable against the interior of the tube. The lead wire for a string anode extends through the slot of the other part. In the formation of an anode string the tubular anodes are threaded onto unspooled insulated wire or cable, a short portion of the insulation is removed at each connector location, and with the tubular anode offset, a connector is secured to the bare wire. The tube is threaded over the connector and the connector locked in place. The connector may be encapsulated by filling the interior with a potting compound or sealant. The connector and process is particularly useful with relatively small diameter titanium, niobium or tantalum tubular anodes.
Abstract:
A clamping device for supporting a workpiece in a clamped condition. The device includes a split head fastener composed of a head having exterior and interior surfaces, and a threaded shaft attached to the head and extending substantially normally from the interior surface. The head is segmented by slots extending from the exterior surface toward the interior surface, and further defines a passageway extending inwardly along the axis from the exterior surface. To clamp a workpiece in the device, a tightening member carried on the shaft is rotated to bring it into contact with the interior surface of the head, in an outer surface region thereof only. This contact forces the segments surrounding the passageway to pivot toward the axis of the passageway, causing clamping of a workpiece received in the passageway.
Abstract:
An electrical connector is disclosed which is particularly adapted to electrically and mechanically connect a transmission conductor to a distribution conductor. The connector includes a C-shaped body having a curved top wall adapted to fit over a transmission conductor. A screw-operated wedge is carried by the bottom of the C-shaped body and includes an elongated recess in the top for supporting the distribution conductor. A conductor interface has a handle or gripping means thereon which allows the same to be easily placed within the connector body between the connectors. The screw positively moves the wedge both in and out so that the clamping action of the connector can be tightened or loosened as desired. A frangible nut prevents overtightening of the screw and a locking washer includes tabs which may be bent into place to prevent the screw from accidentally turning.
Abstract:
A terminal device for connecting an electrical conductor to another unit, e.g. in the form of a terminal strip, comprises a passage for inserting the insulation-stripped end of the conductor which is inclined to another passage in which a clamping screw is received. The screw has a conical nonthreaded portion which bears against the conductor when the screw is tightened and where the passages meet.
