Patent number: 6952336Abstract: A protective element safely dissipates overvoltages which is comprised of a parallel connection of a varistor and an surge arrester. To reduce the capacity of the protective element, the varistor is fashioned as a disc and arranged between a contact pins and the surge arrester. An electrical isolation between contact pin and varistor is ensured by an electrically isolated spacer, in which openings for electrical contact elements are provided to connect the varistor with the cup and the contact pin with the surge arrester. The surge arrester and the spacer are preferably fit positively into the cup.Type: GrantFiled: July 18, 2003Date of Patent: October 4, 2005Assignee: EPCOS AGInventors: Frank Werner, Norbert Krost, Jürgen Boy

Patent number: 6795290Abstract: The invention is directed to a surge arrestor having a middle electrode and at least one outer electrode, in which an electrically conductive spring clip is secured to the middle electrode and exerts a spring power on the outer electrode; in which an electrical component part that is non-conductive at the trigger voltage of the surge arrestor and generates heat given a flow of current is arranged between the spring clip and the outer electrode; in which the spring clip lies against an electrically conductive contact element that is secured to a spacer element using a fusible mass and that is spaced from the outer electrode; and in which, when the fusible mass melts, the contact element is pressed against the outer electrode by the spring clip. The trigger mechanism has the advantage that it reacts very quickly and thereby reduces the formation of sparks and the fire hazard as well.Type: GrantFiled: December 30, 2003Date of Patent: September 21, 2004Assignee: Epcos AGInventors: Peter Bobert, Klaus-Dieter Fuhrmann, Juergen Boy

Patent number: 6724605Abstract: In order to simplify the mountability of electrode terminals in the form of band-like clips on either two-electrode or three-electrode arresters, the clips are resiliently fashioned in a circumferential direction. When such a clip axially projects beyond a foot part of the respective end electrode, the projecting region in a three-electrode arrester can be part of a short-circuit device which electrically connects to the middle electrode, potentially in combination with an auxiliary discharge path.Type: GrantFiled: December 12, 2001Date of Patent: April 20, 2004Assignee: Epcos AGInventors: Jürgen Boy, Peter Bobert

Patent number: 6445560Abstract: A resilient bracket, in the form of an open ring that is placed on the insulator between the two electrodes and whose one end, having two side bars shaped at the sides, forms the short-circuiting link, serves as a device for the external short-circuiting of two electrodes of a gas-filled surge arrester. A spacer, which is made of a material that can be melted and which is inserted between the short-circuiting link and the insulator, holds the side bars at a radial distance from the electrodes. A surge arrester of this sort is suited in particular for arrangement in cartridges for the acceptance of a multiplicity of arresters.Type: GrantFiled: January 12, 2000Date of Patent: September 3, 2002Assignee: Epcos AGInventors: Peter Bobert, Jürgen Boy
