Patent number: 7358839Abstract: A heavy duty relay can safely switch a current of 40 A to 1 kA. The heavy duty relay is provided with a changeover spring which can be resiliently deflected by means of a switching force and with a normally-open contact, against which a contact point of the changeover spring is electrically conductively pressed in a switching position. The normally-open contact is arranged on a normally-open spring contact, which exhibits a higher spring stiffness than the changeover spring and is resiliently deflected in the switching position, and the changeover spring and/or the normally-open spring contact comprises a deflection region at least partially surrounded by a weakened zone. The spring stiffness of the deflection region is reduced relative to the region of the changeover spring and/or the normally-open spring contact surrounding the weakened zone.Type: GrantFiled: January 28, 2005Date of Patent: April 15, 2008Assignee: Tyco Electronics Austria GmbHInventor: Rudolf Mikl

Publication number: 20060181376Abstract: The invention relates to an electromagnetic relay comprising a changeover contact and a working contact, the changeover contact abutting an stop in the open position. The changeover contact interacts via a slide member with an armature plate, which is arranged on a different side of the coil, opposite the changeover contact. The stop comprises an abutment surface, which is arranged below contact buttons of the changeover contact and abuts the changeover contact below the contact buttons in the open position. Improved activation behavior of the relay is achieved as a result of this position of the abutment surface. The useful life of the relay is also lengthened as a result of this embodiment of the stop.Type: ApplicationFiled: December 15, 2005Publication date: August 17, 2006Inventors: Rudolf Mikl, Johann Loy

Patent number: 7026896Abstract: The invention relates to a relay comprising a coil bobbin, a core penetrating the coil bobbin and a yoke. To achieve a high switching force with a low overall height, the cross-sectional area of the core is greater in the region toward the transition to the yoke than in the central region of the coil bobbin. Increased magnetic flux can be conveyed from the core owing to the cross-sectional enlargement and at the same time more coil windings can be arranged in the central region owing to the reduced cross-section there. Both measures act together and allow high switching forces with low overall height.Type: GrantFiled: February 25, 2004Date of Patent: April 11, 2006Assignee: Tyco Electronics Austia GmbHInventors: Rudolf Mikl, Leopold Mader, Bernd Adrian, Johannes Helmreich
