The contact body includes a contact wall that extends around the central axis and that defines a conductor-receiving passage of the contact body proximate to the loading end. The contact wall has an outer surface. The crimp contact also includes a sleeve wall that extends around the central axis and the outer surface of the contact wall proximate to the loading end of the contact body. The sleeve wall is sized to engage a crimping tool and the contact wall is configured to grip a conductor within the conductor-receiving passage when the sleeve and contact walls are deformed by the crimping tool.Type: GrantFiled: May 24, 2010Date of Patent: March 22, 2011Assignee: Tyco Electronics CorporationInventors: Jared Evan Rossman, Andrew Charles Davison, Hung Wei Lord

Patent number: 7896712Abstract: An integral bonding attachment includes an insulated section of a conductive wire with an exposed, uninsulated section. A sleeve covers the insulated and uninsulated sections of the conductive wire, and the sleeve includes a flattened section encasing at least a portion of the uninsulated wire section to form a generally integral structure with the core of the conductive wire. At least one generally tubular section is positioned at an end of the flattened section to engage the insulated section of the conductive wire. An aperture may pass simultaneously through the inner core and flattened sleeve section for attaching the integral bonding attachment to a structure.Type: GrantFiled: December 20, 2006Date of Patent: March 1, 2011Assignee: Tensolite, LLCInventors: David Charles Cecil, Jack Edgar Sutherland

Publication number: 20100206631Abstract: A one piece integral electrical terminal has a mount portion and a wire receiving portion. The wire receiving portion has a continuous annular interior wall having a contact portion with an integral oxide breaker especially suited to breaking through the oxide layer on aluminum wire. The wire receiving portion also has a sealing portion with at least one integral seal ring. An electrical cable is made by crimping the electrical terminal to an aluminum wire using a modified hexagonal crimp.Type: ApplicationFiled: February 16, 2009Publication date: August 19, 2010Inventors: Kenneth J. Peters, William L. Atenburg

Patent number: 7709743Abstract: An integrated insulator sealing and shielding assembly includes a rubber housing having a plurality of radial weathersheds and a tapered end adjacent an endmost radial weathershed. A metal fitting is disposed adjacent to the endmost radial weathershed and receives the tapered end. A collar assembly is disposed at an upper end of the metal fitting and includes two apertures between an outer surface thereof and the rubber housing for receiving a sealant. At least one sealing surface, preferably four, is disposed between the collar assembly and a bottom end of the rubber housing for securing the connection therebetween.Type: GrantFiled: October 15, 2007Date of Patent: May 4, 2010Assignee: Hubbell IncorporatedInventors: Robert A. Bernstorf, Bastiaan H. Van Besouw

Patent number: 7495172Abstract: A cable sealing end includes a base fitting configured for mounting on a base; a top fitting configured for securing an overhead conductor; an insulating body made of polymeric material; a conductive connection device configured to form a connection between a cable conductor and the top fitting; and a supporting element. The supporting element includes an elongated metal body; a top plate disposed on the elongated metal body and securable to the top fitting; and a metallic cylindrical structural component. The structural component projects into an interior of the insulating body and has a base flange disposed adjacent to the base fitting. The structural component has a length of one quarter to one third of a length of the insulating body. An entire length of the elongated metal body and the structural component, with the exception of the base flange, are embedded in the insulating body.Type: GrantFiled: August 3, 2007Date of Patent: February 24, 2009Assignee: NKT Cables GmbHInventor: Uwe Amerpohl

Patent number: 7491071Abstract: An end portion of a shielding layer is inserted between an inner tubular portion and an outer tubular portion of a shield ring by the use of a tubular pushing jig, and in this condition when a shield shell is inserted into the shield ring in a direction opposite to the direction of inserting of the shielding layer, the shield ring is pressed by the shield shell, so that a gap between the inner tubular portion and the outer tubular portion decreases, and the shielding layer is firmly held between the inner and outer tubular portions, thereby achieving a fixed condition of the shielding layer. Namely, the shield ring and the shield shell are fixed to the end portion of the shielding layer.Type: GrantFiled: November 12, 2007Date of Patent: February 17, 2009Assignee: Yazaki CorporationInventors: Tsuyoshi Hamai, Akihiro Nagao

Patent number: 7431619Abstract: A remote inspection device is provided for inspecting visually obscured locations. The device is generally comprised of a imager housing and a display housing disposed on opposite ends of a modular, flexible cable. An imaging device and one or more light sources are embedded in the end of the cylindrical imager housing. A display housing is coupled to the other end of the flexible cable and configured to be grasped by a user of the device. A display device supported by the display housing receives a video signal from the imaging device and converts the video signal to a video image. The flexible cable can be removably attached to other components with a detachable coupling. The detachable coupling is adapted to facilitate movement of the coupling through confined spaces and inhibit relative axial rotation. Components of the coupling can have tapered mating surfaces to inhibit longitudinal movement within the coupling.Type: GrantFiled: August 24, 2007Date of Patent: October 7, 2008Assignee: Perceptron, Inc.Inventors: Al Boehnlein, Paul J. Eckhoff, Brandon Watt, Tye Newman, Jeffrey John Miller
