Publication number: 20080045058Abstract: A high voltage loadbreak bushing insert includes an insulative housing having a first end section, a second end section opposite the first end section, a mid-section disposed between the first and second end sections and a transition shoulder portion disposed between the second end section and the mid-section. The second end section is dimensioned for insertion into a power cable elbow connector and the mid-section is dimensioned to be sealed against an elbow cuff of the power cable elbow connector. The transition shoulder portion includes at least one raised portion protruding radially outwardly from the transition shoulder portion. The raised portion is adapted to force the elbow cuff of the power cable elbow connector to expand in a radially outward direction upon withdrawal of the second end section from the power cable elbow connector, thereby venting a cavity formed between the bushing insert and the power cable elbow connector.Type: ApplicationFiled: May 10, 2007Publication date: February 21, 2008Inventors: Frank Stepniak, Alan Borgstrom, Larry Siebens

Patent number: 7311563Abstract: A set screw electrical connector assembly includes an electrical connector and a set screw drive plug. The connector includes at least one set screw portal sized to accommodate a set screw therein. The set screw drive plug is formed of electrically insulative material and is configured to engage and drive the set screw into the connector. The connector assembly may include an insulative housing formed about the connector for providing a water tight seal with a cable terminated to the connector.Type: GrantFiled: January 6, 2006Date of Patent: December 25, 2007Assignee: Thomas & Betts International, Inc.Inventors: Larry N. Siebens, Alan Borgstrom

Patent number: 7150098Abstract: In a method for forming an electrical cable connector having a voltage detection test point, an insulative shield is first molded from a thermoplastic and a conductive voltage detection test point terminal is inserted within the plastic insulative shield. After the pre-assembled insulative plastic shield and test point terminal are positioned adjacent the opening of the conductive outer shield, and after the conductive outer shield and an internal conductor are positioned within a mold cavity, an inner insulative housing is molded within the conductive outer shield and around the internal conductor.Type: GrantFiled: October 13, 2004Date of Patent: December 19, 2006Assignee: Thomas & Betts International, Inc.Inventors: Alan Borgstrom, John Knight

Publication number: 20060178026Abstract: A method for forming a separable electrical connector having an electrical interface surface includes the steps of molding an interface shell from a thermoplastic, placing the interface shell against an electrical interface portion of a mold cavity and molding a housing within the mold cavity. When placed in the mold cavity, the interface shell provides a barrier to the mold cavity interface portion, wherein the housing is isolated from the electrical interface potion of the mold cavity by the interface shell. The shell has an inner surface and an outer surface and the housing is bonded to one of the inner and outer surfaces, wherein the other of the inner and outer surfaces of the shell defines the electrical interface surface of the electrical connector.Type: ApplicationFiled: March 22, 2006Publication date: August 10, 2006Inventors: Alan Borgstrom, Frank Stepniak

Publication number: 20050142941Abstract: An electrical cable connector having a voltage detection test point generally includes an internal conductor, an inner insulating sheath surrounding the conductor, a conductive outer shield surrounding the insulating sheath, a separately molded plastic insulative shield disposed adjacent an opening formed in the conductive outer shield and held by the inner insulating sheath and a conductive voltage detection test point terminal disposed within the plastic insulative shield, wherein the test point terminal is capacitively coupled to the internal conductor for external testing of a voltage of the connector. In a preferred method for forming an electrical cable connector, such as a loadbreak power cable elbow connector, having a voltage detection test point, an insulative shield is first molded from a thermoplastic and a conductive voltage detection test point terminal is inserted within the plastic insulative shield. An outer shield is then molded from a conductive material.Type: ApplicationFiled: October 13, 2004Publication date: June 30, 2005Inventors: Alan Borgstrom, John Knight

Patent number: 5856634Abstract: A recoverable article includes an inner resilient radially elastomeric tubular member 2 that is held in its expanded configuration by an outer relatively rigid shell 6. The interface between the member 2 and the shell 6 comprises a plurality of circumferentially-spaced parallel strips 4 coated onto the member 2. The strips 4 prevent the shell 6 from bonding to the member 2 in those regions. The shell 6 is castellated with its valleys 12 adjacent the edges of the strips 4. The lands 8 of the castellated shell 6 overlying the strips 4 can be peeled back to permit the resilient member 2 to recover towards its original configuration, for example around a power cable splice.Type: GrantFiled: March 19, 1997Date of Patent: January 5, 1999Assignee: Raychem CorporationInventor: Alan Borgstrom
