| 20110193674 | OVERVOLTAGE PROCTECTION DEVICE HAVING ONE OR MORE PARALLEL-CONNECTED OVERVOL TAGE-LIMITING ELEMENTS LOCATED IN ONE PHYSICAL UNIT - The invention relates to an overvoltage protection device having one or more parallel-connected voltage-limiting elements which are located in one physical unit, such as varistors, diodes or means of this type configured in the form of a disc, comprising a shell apparatus in order to electrically disconnect the overvoltage-limiting elements when they are thermally overloaded, and means for indication and/or signalling of the fault state which then occurs, wherein the switching apparatus is connected via a means which can be released thermally, such as adhesive or a solder, to a connecting contact of the at least one overvoltage-limiting element, and/or to an external terminal contact or plug contact. According to the invention, the switching apparatus is in the form of a solid U-shaped switching fork, the fork tines of which run essentially parallel to the side surfaces of the overvoltage-limiting element, holding the latter in the space between the tines. At least one of the fork tines rests on the at least one connecting contact and is fixed there via the means which can be released thermally wherein, when disconnection occurs, the disconnection slide is moved with the switching fork being driven and, in the process, the connection point between the fork tines and the connecting contact represents a fulcrum for the switching fork movement. | 08-11-2011 |
