Patent number: 6210239Abstract: For a contact element with a screw-type terminal for electric conductors, wherein the contact element comprises a conductor connection part provided with a bore, into which the conductor is insertable and clampable by means of a screw insertable at right angles to the bore and/or conductor into a threaded bore in the conductor connection part, and wherein between the end of the screw directed towards the conductor and the conductor a wire protection plate is provided in the bore, it is proposed to make the wire protection plate substantially L-shaped, an angled foot thereby being formed, to insert the wire protection plate into the bore in such a way that the foot is situated at the base of the bore, and to provide the foot with lateral, barb-like mouldings which, upon insertion of the wire protection plate, dig into the wall of the bore.Type: GrantFiled: February 2, 1999Date of Patent: April 3, 2001Assignee: Harting KGaAInventors: Dietmar Harting, Albert Ferderer

Patent number: 6142485Abstract: A chuck for rotary tools with a cylindrical chucking shank encloses such shank with a basic body. A radial through-hole in basic body serves to receive a clamping screw which applies pressure to a clamping member which is seated inside a through-hole between the clamping screw and chucking shank. A clamping member is provided with a radial projection and the through-hole with a cross-sectional narrowing along its inner end. In between the radial projection and the narrowing is an elastically compressible spring element which, due to its return force, lifts the clamping element away from the chucking shank and pushes it back into the through-hole when it is not under tension from the clamping screw.Type: GrantFiled: April 30, 1999Date of Patent: November 7, 2000Assignee: Kennametal Inc.Inventors: Gebhard Muller, Michael Schuffenhauer, Martin Prey

Patent number: 6123573Abstract: A strain relief assembly is readily adaptable to clamp electrical cords of various sizes and/or shapes. The assembly is provided with differently configured clamping surfaces that may accommodate a variety of cords without compromising the ability of the clamp assembly to secure the various cords, and a user of the assembly may easily select a desired clamping surface. The assembly includes a base clamp member with a clamping surface, a securing member that may also include a clamping surface, and an insert that includes a clamping surface.Type: GrantFiled: July 20, 1999Date of Patent: September 26, 2000Assignee: Pass & Seymour, Inc.Inventor: Gerald R. Savicki, Jr.

Patent number: 6116966Abstract: Disclosed are male and female electrical contacts for transferring high electrical power between a master assembly and a tool assembly of a robotic tool changer. The male and female contacts have corresponding outwardly-projecting and inwardly recessed conical or frusto-conical contact surfaces which tend to cause contaminants to slide off the surface of the contacts. The contacts may instead have corresponding outwardly-projecting and inwardly recessed contact surfaces having spherical, frusto-spherical, ellipsoid, frusto-ellipsoid, ovoid, or frusto-ovoid shapes. Each of the contacts includes a contact base for attaching the contact to one of the assemblies of the robotic tool changer and a contact tip removably attached to the contact base, thereby allowing the contact tip to be replaced without detaching the contact base from the robotic tool changer. The contact tip of either or both of the electrical contacts is mounted in such a way as to have compliance in at least one direction.Type: GrantFiled: April 17, 1998Date of Patent: September 12, 2000Assignee: ATI Industrial Automation, Inc.Inventors: Robert D. Little, Prasad Balakrishnan

Patent number: 6084188Abstract: A molded case circuit breaker having separable main contacts and an operating mechanism utilized to cause the separable main contacts to open and close. A trip unit is provided to actuate the operating mechanism in desirable circumstances. The circuit breaker has external terminals which are connectable with an external load and an external power supply. A collar is used to interconnect the circuit breaker terminals with the load and power supply. The terminal collar in this case is non-symmetrical. The non-symmetrical collar provides two functions: the first function is that the path of electrical continently between adjacent collars is enlarged for higher voltage applications because of the non-symmetrical nature of each collar; secondly, the circuit breaker case has a seat therein which has the same cross-section as the non-symmetrical collar, so that the collar can only be inserted therein in one cross-sectional orientation.Type: GrantFiled: August 18, 1999Date of Patent: July 4, 2000Assignee: Eaton CorporationInventors: Robert W. Mueller, Thomas A. Whitaker, Wayne C. Sumpman

Patent number: 6061230Abstract: A panelboard/switchboard assembly for accommodating bolt-on modules, plug-in modules and lugs. The panelboard/switchboard includes vertical, edge forward bus bars having a plurality of openings formed therein. The edge forward alignment allows plug-in modules to be mounted to the bus bars. The openings in the bus bars receive bolts for mounting straps to the bus bars and for mounting lugs to the bus bars. The openings have a shape having at least one linear element and receive a bolt having an anti-rotation portion with a similar shape. The interference between the opening and the anti-rotation portion of the bolt prevents the straps, and the modules connected to the straps, from rotating.Type: GrantFiled: December 8, 1997Date of Patent: May 9, 2000Assignee: General Electric CompanyInventors: Kevin D. Mazzella, Kevin F. Nolan, Rick A. Vonrotz, Thomas F. Vrnak, Melanie A. Lewis, Grady W. Broadnax, Jr., Robert R. Leclair, Robert B. Wallace, Jeremy Palmer, Hamon L. Craft

Patent number: 6042430Abstract: A shearable fastener has a threaded shank (10) adapted for engagement with a threaded bore and a head (12) formed for engagement with a drive tool. The shank (10) is formed with a series of axially separated weakenings (14) defining a series of shear planes, the weakenings (14) being formed such that the applied torque necessary to cause the shank (10) to shear increases progressively from the shear plane (14) furthest from the head (12) to the shear plane (14) nearest the head (12).Type: GrantFiled: October 3, 1997Date of Patent: March 28, 2000Assignee: B & H (Nottingham) LimitedInventor: David John Hollick

Patent number: 6000963Abstract: For a contact element with a connection for stranded conductors, in particular a contact element for high currents, it is proposed that the connecting end of the contact element be provided with a transverse bore in which the stranded conductor can be inserted, that the contact element be further provided with an axial threaded bore which reaches as far as the transverse bore, and that a clamping screw provided with a conical point be screwed into the threaded bore, and thus into the stranded conductor.Type: GrantFiled: July 13, 1998Date of Patent: December 14, 1999Assignee: Harting KGaAInventors: Dietmar Harting, Klaus Olejarz

Patent number: 5989077Abstract: A header assembly for coupling a cardiac lead to a cardiac stimulator is provided. The header assembly includes a header that has a bore for receiving one end of the cardiac lead. The bore has a first longitudinal axis. A connector housing is coupled to the header and has a second bore substantially aligned with the first bore. A biasing member is disposed within the connector housing and has a portion projecting into the second bore to bias the end of the cardiac lead against the walls of the second bore. A set-screw is threadedly coupled to the housing and is operable to secure the cardiac lead to the connector housing when tightened.Type: GrantFiled: March 13, 1998Date of Patent: November 23, 1999Assignee: Intermedics IncInventors: Roy T. Mast, Daniel J. Cooke
