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: An electrical connector includes an insulating housing. The insulating housing has an inner wall, a first end, and a second end. The inner wall of the insulating housing defines a cavity and a groove, the groove including a groove wall, the groove wall extending from the cavity radially into the insulating housing to a groove depth. The electrical connector also includes an electrical component in the cavity; an electrically conductive shell at an outer surface of the insulating housing; and a plug in the housing, the plug including a body and projection that radially extends from the body, the projection being received in the groove, where the groove wall applies more than 35 pounds (lbs) of force on the plug in a direction that is toward the electrical component.

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.

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: 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.
