  • Patent number: 7632120
    Abstract: A separable loadbreak connector and system includes a connector having a contact tube with an axial passage therethrough, and a contact member slidably mounted within the axial passage and movable therein during a fault closure condition. The contact member is axially movable within the passage with the assistance of an arc quenching gas during the fault closure condition, and a shock absorbent stop element is mounted to the contact tube and limiting movement of the contact member in the fault closure condition.

  • Publication number: 20090275223
    Abstract: A dual interface separable insulated connector comprising a faraday cage molded over a bus bar for use in an electric power system and a method of manufacturing the same are provided. The faraday cage can be disposed within a semi-conductive shell. The configuration of the separable insulated connector can provide for easier bonding between the faraday cage and insulating material. Additionally, the configuration can eliminate or reduce the need to coat the bus bar with an adhesive agent and to smooth the metal bus bar to remove burrs, other irregularities, and sharp corners from the bar. Manufacturing the dual interface separable insulated connector can include molding a semi-conductive rubber faraday cage over a conductive bus bar, inserting the faraday cage into a shell, and injecting insulating material between the faraday cage and shell.

  • Publication number: 20090255106
    Abstract: Removal of a conventional separable insulated connector from an electric power system often results in a shortened electric cable. An extender for a separable insulated connector enables the separable insulated connector to connect to a shortened cable. A conventional cable adapter is inserted into the extender, which includes a conductive connector for accepting the shortened cable and a conductive rod for carrying electric power from the shortened cable to the separable insulated connector. The extender also includes an inner semi-conductive layer that borders the conductive rod and compression connector, an outer semi-conductive layer, and a insulating layer between the two semi-conductive layers. The extender is inserted into a separable insulated connector, which is then connected to the electric power system.

  • Publication number: 20090233472
    Abstract: An electrical connector, such as a bushing insert, with a fault-closure lockout feature includes a housing with an inner bore having opposite ends. One end has an opening providing access to the inner bore. A piston-contact element is movable between first and second axially spaced positions within the inner bore. During fault conditions, the piston-contact element moves from the first position to the second position to accelerate connection with a male contact of another electrical connector, such as a cable connector, thereby inhibiting the formation of flashover or electrical arc. After fault closure, a lockout member on the piston-contact element prevents moving the piston-contact element from the second position to the first position.

  • Publication number: 20090215313
    Abstract: Separating connector assemblies of a separable connector system. The separable connector assemblies include one or more pairs of connectors configured to engage and disengage one another in electrical connection and disconnection operations, respectively. An operator can disengage the connectors by pushing the connectors together and then pulling the connectors apart. Pushing the connectors together shears interface adhesion between the connectors, making it easier for the operator to pull the connectors apart. One of the connectors can include a nose end having an undercut segment configured to not engage an interior surface of the other connector when the connectors are engaged. Limiting the surface area of the nose end that interfaces with the interior surface of the other connector reduces surface adhesion and a pressure drop when separating the connectors, making separation easier to perform.

  • Publication number: 20090215307
    Abstract: Separable connector assemblies include one or more pairs of connectors that engage and disengage one another in electrical connection and disconnection operations, respectively. An operator can disengage the connectors by pushing the connectors together and then pulling the connectors apart. Pushing the connectors together shears interface adhesion between the connectors, making it easier for the operator to pull the connectors apart. An indicator integral or coupled to one of the connectors can indicate whether the first and second connectors are in the pushed-in-position. A window in the other connector includes an opening, channel, and/or translucent or semi-translucent material through which the indicator may be seen. The window and/or one or more vents in a tubular member of one of the connectors can include a channel that provides an air path for ingress of air between the connectors, to thereby remove or reduce a vacuum or partial vacuum between the connectors.

  • Publication number: 20090215325
    Abstract: Stiff and soft materials each provide certain advantages when used in the manufacture of separable insulated connectors, such as elbow and T-body connectors. Utilizing a shell or an insert that includes one section made from a stiff material and one section made from a soft material can provide a separable insulated connector that capitalizes on the advantages associated with both types of materials. The stiff materials and soft materials can be placed strategically on the shell or insert of the separable insulated connector to maximize the advantages of each material. For example, the stiff material can be used to form a section of the separable insulated connector where strength and durability is most desirable, and conversely, the soft material can be used to form a section of the connector where flexibility is desirable. A relatively stiff band can be provided around a relatively soft portion of a connector.

  • Publication number: 20090108847
    Abstract: A fuse test and ground device includes an insulated housing with a bore that extends from the front of the housing towards the rear of the housing. An electrical contact is disposed partially within the bore. A current interrupter, such as a fuse, is electrically connected between the contact and a testing ground lead. An eye, having it's surface insulated by the housing, can be attached to the housing and provide a connection point for manipulation of the device. A grounding bore extends from a second aperture into the housing and provides an electrical connection to the contact. A grounding plug can be connected to ground on one end and inserted into the grounding bore to create a permanent ground for the device. An annunciator is connected to the current interrupter such that the annunciator provides an indication when a current flows through the current interrupter.
