Patent number: 8328569Abstract: 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.Type: GrantFiled: May 20, 2011Date of Patent: December 11, 2012Assignee: Cooper Technologies CompanyInventors: Paul Michael Roscizewski, David Charles Hughes

Publication number: 20110151696Abstract: A loadbreak elbow includes a sleeve having an upper portion defining a fuse housing and a lower portion defining a cable entrance. A shield housing is positioned within the upper portion and includes a first opening for receiving a cable connector and second opening in communication with the first opening for receiving a fuse. A fuse is positioned in the second opening of the shield housing and a fuse ferrule is threadably coupled to the cable connector in the first opening. The cable connector includes a retaining feature, and the shield housing includes a retaining means to engage the retaining feature so as to prevent the cable connector from rotating within the shield housing while the fuse ferrule is being coupled to the cable connector.Type: ApplicationFiled: December 17, 2009Publication date: June 23, 2011Applicant: Cooper Technologies CompanyInventors: Paul Michael Roscizewski, Mary Alice Park

Patent number: 7958631Abstract: 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.Type: GrantFiled: April 11, 2008Date of Patent: June 14, 2011Assignee: Cooper Technologies CompanyInventors: David Charles Hughes, Paul Michael Roscizewski

Patent number: 7909635Abstract: 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.Type: GrantFiled: December 22, 2009Date of Patent: March 22, 2011Assignee: Cooper Technologies CompanyInventors: David Charles Hughes, John Mitchell Makal, Michael John Gebhard, Sr., Paul Michael Roscizewski

Patent number: 7854620Abstract: 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. For example, the conductive material can be overmolded around the non-conductive material, or the non-conductive material can be insert molded within the conductive material. The molding 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 a nose end of the contact tube.Type: GrantFiled: December 22, 2008Date of Patent: December 21, 2010Assignee: Cooper Technologies CompanyInventors: David Charles Hughes, Paul Michael Roscizewski
