Embodiment Construction

[0024] Figures 1 to 3 shown with - only in figure 1 Shown in the middle is an overvoltage protection element 1 of a housing 2 , wherein an overvoltage limiting element 3 is arranged in said housing 2 . In the exemplary embodiment shown, a "double varistor" is used as overvoltage-limiting element 3, in which two varistor disks or two ceramic disks are placed between them The metal parts are connected to each other, so that the "double varistor" is formed as a whole as one part, even though "functionally" there are two varistors. Of course, a “standard” varistor or other overvoltage limiting elements such as gas-filled surge protectors can also be arranged inside the housing 2 . The overvoltage protection element 1 , which is designed as a "protective plug" in the drawing, has two connecting elements 4 , 5 designed as plug pins, which can be plugged into corresponding sockets provided in the lower part of the device. .

Abstract

The invention provides an overvoltage protection element, with a housing, an overvoltage-limiting component, two connecting elements as well as an elastic separation tongue, the separation tongue in a standard state of overvoltage protection element is connected with the first connecting element in a conductive contact by the first end and is connected with the overvoltage-limiting component in a conductive contact by the second end, and the second end of the separation tongue is connected with the overvoltage-limiting component by the welding point, and the welding connection is separated when the temperature of the overvoltage-limiting component exceeds the pregiven operating value, thereby the formed separation point separates the electric aspect when the overvoltage-limiting component is thermal overload. In order to guarantee that the defective overvoltage-limiting component, high-insulating intensity and creepage intensity are reliably separated, and the separation tongue overcomes elastic force itself when connected with the overvoltage-limiting component by the welding point on the second end, and is extends and deflects relative to a loose state thereof, thereby the second end of the separation tongue not only executes the linear motion F1, but also executes the gyroscopic motion F2, when the welding connection is separated.

Description

technical field [0001] The invention relates to an overvoltage protection element having a housing, at least one overvoltage-limiting element, in particular a varistor, arranged in the housing, at least two elements for disabling the overvoltage The protective element is electrically connected to the connecting element on the current or signal line to be protected and to the elastic separating tongue as an electrically conductive separating element, which in the standard state of the overvoltage protective element has its first end in contact with the The first connecting element is in electrically conductive contact and is in electrically conductive contact with the overvoltage limiting element with its second end, wherein the second end of the separating tongue is connected to the overvoltage limiting element via a soldering point. The elements are connected and separated at the welding point between the overvoltage-limiting element and the second end of the separating tongu...
