Abstract:
A variable diameter termination includes an elastomeric tubular housing having a first portion with a first inner diameter, a second portion with a second inner diameter, and a third portion disposed between the first portion and the second portion and with a transition inner diameter. The elastomeric tubular housing is disposed on a tubular core that includes a first portion with a third outer diameter, a second portion with a fourth outer diameter, and a third portion disposed between the first portion and the second portion and with a transition outer diameter. The first portion of the elastomeric tubular housing is disposed over the first portion of the tubular core, the second portion of the elastomeric tubular housing is disposed over the second portion of the tubular core, and the third portion of the elastomeric tubular housing is disposed over the third portion of the tubular core.
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.
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.
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.
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.
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.
Abstract:
A separable connector shield housing includes a layer of conductive material disposed at least partially around a layer of non-conductive material. The layers are molded together. The conductive material can be overmolded around the non-conductive material, or the non-conductive material can be insert molded within the conductive material. This results in an easy to manufacture, single component shield housing with reduced potential for air gaps and electrical discharge. The shield housing defines a channel within which at least a portion of a contact tube may be received. A contact element is disposed within the contact tube. The conductive material substantially surrounds the contact element. The non-conductive material can extend along an entire length of the contact tube and other components, or it may only extend partially along the contact tube. The non-conductive material can include an integral nose piece disposed along the contact tube.

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 comers 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.
