Abstract: An assembly comprising a tap plug having therein an axially fixed nut and including an externally threaded portion threaded into a cable connector lug, a bushing having therein an internally threaded bore, and a stud including an externally threaded first end threaded into the nut, and an externally threaded second end threaded into the bushing bore.

Abstract: A separable connector module for live switching of shielded electrical power cable comprises a rod contact and a rod-shaped follower molded about a reinforcing pin fixed to one end of the rod contact. The follower is of thermoplastic ablative material consisting essentially of acetal resin loaded with melamine; the melamine constituting between one-fourth to about one-half the ablative material by weight.

Abstract: A module of the type having an elongated insulating housing, a contact-receiving bore in the housing, and a bore contact mounted in the housing in communication with the inner end of the bore, for receiving a rod contact of a matching module, is provided with an improved gas-trap valve which comprises a sliding segment gate. The valve is mounted adjacent the outermost end of the bore. It comprises an annular valve casing member having a central opening in alignment with the bore and a chamber in the casing in which the gate segments slide between a pair of parallel and opposed walls in a plane perpendicular to the bore and are biased in a closed position. A depression in the outer faces of the valve segments permits the valve segments to be forced into the open position in response to pressure by a rod contact inserted into the opening.

Abstract: A rod connector module of the type comprising an insulating housing containing a contact rod support, a receiving cone in the housing extending from the exterior toward the support, and a conductive contact rod fixed at one end to the support and extending toward the exterior along the axis of the well is provided with a layer of electrically resistive voltage stress grading material of the inside surface of the well and electrically connected to the supported end of the rod.

Abstract: A separable connector module for connecting shielded electrical power cable and of the type including an insulating housing containing a bore contact assembly. The bore assembly includes a set of resilient receiving contact fingers attached to a rigid snuffer tube having on its inside wall a liner of ablative material. The improvement comprises that the portion of the snuffer liner adjacent the contacts is counterbored to have a greater inside diameter than the remaining portion of the snuffer liner. Such counterboring improves the performance of the connector for capacitive switching at relatively high voltages and in addition reduces the tendency for clear and restrike failures on typical distribution circuits.

Abstract: A high voltage electrical cable separable connector module comprises an internal gas flow-restricting gasket to restrict an undesirable flow of ionized arc-generated gases from the module upon live disconnection of the module from an electrical circuit. By restricting the flow of ionized gas in the module, its arc interrupting capability is enhanced, and at the same time, the risk of an arc restrike upon disconnection is appreciably reduced.

Abstract: A separable connector module for connecting shielded electrical power cable. It is of the type including an insulating housing containing a cable insert member. A male contact rod assembly, including a metal contact rod, is fixed at one end to the insert member. An insulating arc follower is fixed to the rod at its other end. The improvement comprises that the arc follower overlaps a beveled portion of the shoulder of the contact rod to favorably affect the configuration of the potential field there.

Abstract: A separable connector module for connecting shielded electrical power cable. It is of the type including an insulating housing containing a cable insert member. A male contact rod assembly, including a metal contact rod, is fixed at one end to the insert member. An insulating arc follower is fixed to the rod at its other end. An insulating mounting pin extends from the end of the rod and along at least a portion of the interior of the follower. The improvement comprises an electrically conducting coating on the mounting pin and in electrical contact with the rod.
