  • Patent number: 8152547
    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.

  • Patent number: 8151364
    Abstract: A method of authenticating a remote service (104) to a user (102) via a communications network (106) is disclosed. The remote service (104) obtains a service authentication code that has been generated, using a code generation algorithm, based on a first secret key. The service authentication code is communicated to the user (102) via the communications network (106) and received, or entered, into an authentication device (106) associated with the user (102). The authentication device (106) then generates, using the same code generation algorithm, an expected code value based on a second secret key and compares the expected code value to the service authentication code. Responsive to the comparison, and in the event that the expected code value correlates with the service authentication code, the authentication device (106) generates a response that indicates to the user (102) the authenticity of the remote service (104).

  • Publication number: 20120030944
    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: 20110287652
    Abstract: An adapter for connecting a 600 ampere deadbreak bushing to a pull-on and pull-off deadbreak elbow used for normally non-current carrying applications. The adapter comprises a two part separable assembly having first and second ends. The first end is threaded to mate with a threaded opening in the deadbreak bushing and the second end is threaded to mate with a threaded opening in a lug of the deadbreak elbow. The two part separable assembly is coupled together with the first part of the assembly that is screwed into the deadbreak bushing and has a groove that snaps (latches) into a corresponding latching ring in a molded insert of the deadbreak elbow that surrounds the second part of the assembly screwed into the lug inside of the deadbreak elbow. Other latching mechanisms may be used to mechanically and electrically couple together the first and second parts of the adapter assembly.

  • Patent number: 7963783
    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.

  • Patent number: 7958631
    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.

  • Patent number: 7950940
    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.

  • Patent number: 7909635
    Abstract: A jacket sleeve with grippable tabs provides protection to exposed portions of cable that are connected to an electrical connection. The jacket sleeve can be made as part of the electrical connector or may be connected subsequent to its creation through the use of glues or other adhesives. The jacket sleeve can be made of a material that is more pliable than the electrical connector, making it easier for a lineperson to place the sleeve over an exposed portion of cable. The jacket sleeve can include holes or slots either in the sleeve or in tabs that are attached to the sleeve. A lineperson can place one or more fingers into each hole or slot in order to get a better grip on the sleeve and pull the sleeve over the exposed portion of cable with less slippage and effort on the part of the lineperson.
