Patent number: 7088207Abstract: An electrical switching device for fault-current, overcurrent and short-circuit current protection, has a contact point in a current path and a switching mechanism for permanently opening the contact point. The switching device further has a configuration for detecting the fault current, the overcurrent and the short-circuit current, and contains two permanent magnets and a core. The core is disposed between the like poles of the permanent magnets which point toward one another and one of which is fixed and the other is guided such that it can move. The permanent magnets are at least partially surrounded by a coil through which a fault, an overcurrent or a short-circuit current flows. When a current flow occurs in the coil, the magnetic field is changed causing a relative movement of the moving part, and the movement is transmitted to the contact point.Type: GrantFiled: May 23, 2003Date of Patent: August 8, 2006Assignee: ABB Patent GmbHInventors: Bernd Siedelhofer, Winrich Habedank, Jörg Puhr-Westerheide, Heinz Throm, Walter Kahl, Klaus Fritsch

Patent number: 6778368Abstract: An electrical service distribution board is accommodated in a housing, has a feed conductor that is inserted into the housing and has outgoer conductors that lead to individual loads. Electrical service devices with different protection tasks, such as fault current protection, short circuit or over-current protection and the like, which can be connected to the feed conductor and to the outgoer conductors by a plug connection via a connection system which contains connection conductors connected to them. A mounting plate is providing for holding the service devices, with the connection conductors disposed underneath the mounting plate and the mounting plate having openings into which plug elements which are disposed on the service devices can be inserted.Type: GrantFiled: September 23, 2002Date of Patent: August 17, 2004Assignee: ABB Patent GmbHInventors: Winrich Habedank, Peter Heilig, Richard Kommert, Heinz-Erich Popa, Jörg Puhr-Westerheide, Bernd Siedelhofer, Helmut Stritt, Karl-Thomas Werner

Publication number: 20020168903Abstract: A description is given of a quick-fastening device for fixing an installation unit on a carrying-rail configuration. The carrying-rail configuration has a carrier plate and a hat-profile rail. Integrally formed on the carrier plate is a resilient snap-action hook with a nose that is oriented in the direction of the hat-profile carrying rail and is snapped into one depression on the narrow side wall of the installation unit.Type: ApplicationFiled: April 11, 2002Publication date: November 14, 2002Inventors: Winrich Habedank, Klaus-Peter Eppe, Ralf Weber

Publication number: 20020149462Abstract: A service switching device is described. The service switching device has a thermal release, an electromagnetic release, a switching mechanism with a latching point, a contact point with a moving contact piece and a stationary contact piece. When an over-current condition occurs, the thermal release unlatches the latching point so that the contact points are opened permanently and, when a short-circuit current occurs, the electromagnetic release moves the moving contact piece to the open position. The service switching device has a housing and an associated actuator in the form of a piezoelectric bending strip, which likewise acts on the latching point in order to open the contact point permanently, with a fault current detection device being provided, whose output signal drives the actuator when a fault current occurs.Type: ApplicationFiled: April 11, 2002Publication date: October 17, 2002Inventors: Winrich Habedank, Walter Kahl, Bernd Siedelhofer, Ralf Wieland

Patent number: 6412572Abstract: A battery-powered hand-guided power tool is provided, such as a hammer, includes a tool housing 3 that contains an electric motor M, a grip housing 2 and a rail-and-channel structure 36, 37, 54, 55 for releasable mounting of a rechargeable battery pack 50. The battery pack 50 is locked in an operative position on the housing 3 in which electrical contacts (51) of the battery pack 50 and associated electrical contacts 42 of the tool housing are electrically connected along a contact length extending in a longitudinal direction of the rail-and-channel arrangement. A latch structure 18,19 located on the tool housing 3 is movable between a latched position and a release position. When the latch structure 18,19 is moved from the latched position into the release position, the battery pack 50 can be moved in the direction of the longitudinal extent of the rail-and-channel structure 36, 37, 54, 55 out of the operative position and can be removed from the tool housing 3.Type: GrantFiled: March 12, 2001Date of Patent: July 2, 2002Assignee: Black & Decker Inc.Inventors: Winrich Habedank, Klaus-Dieter Arich

Patent number: 6109364Abstract: A rotary hammer with a tool holder and a hammer mechanism for the transmission of impact energy onto the drilling and/or chiselling bit in the tool holder has a switching device which with a single actuator makes it possible to switch between pure drilling operation, rotary hammering operation and pure hammering operation. The switching device acts on a coupling with which the hammer mechanism is couplable with a rotatingly driven intermediate shaft, and has a slide part for shifting a toothed wheel between a first position for the rotary driving of the tool holder and a second position in which no rotary driving of the tool holder takes place. The coupling for the hammer mechanism can be separated by a cam part coupled in untwistable manner with the actuator.Type: GrantFiled: November 20, 1996Date of Patent: August 29, 2000Assignee: Black & Decker Inc.Inventors: Ulrich Demuth, Winrich Habedank
