Embodiment Construction

[0048] figure 1 A first exemplary embodiment of an overload protection arrangement 1 for protecting an overvoltage protection structural element 2 is shown in section. The overload protection assembly 1 comprises a structural overvoltage protection element 2 , which is electrically connected via a first connection element 3 and via a second connection element 4 to a current conducting element arranged on a carrier 5 , which is designed here as a printed circuit board.

[0049] The first coupling element 3 comprises a heat-sensitive contact element 6 in the illustrated embodiment. In detail, in figure 1 The heat-sensitive contact element 6 shown in is designed as a low-temperature solder and thus forms the thermal separation point of the overvoltage protection component 2 . In the event of a thermal overload, the heat-sensitive contact element 6 melts, thereby breaking the mechanical contact formed by the contact element 6.

Abstract

The invention relates to an overload protection assembly for protecting an overvoltage protection structural element. The assembly comprises at least one overvoltage protection component, two couplingelements for coupling the overvoltage protection component to a current or signal path to be protected, a support with a current-conducting element and at least one actuator, the first coupling element comprises a thermosensitive contact element, at least one overvoltage protection component is connected with to the support by a first pole via the thermo-sensitive contact element, a second pole is connected to a current-conducting element of the support via a second coupling element, and the at least one overvoltage protection component can be brought into a second position in the event of thermal overload by means of at least one actuator, in which electrical contact via the temperature-sensitive contact element is interrupted. The overload protection assembly is characterized in that the second coupling element is constructed and arranged such that it enables movement of the overvoltage protection structural element from the first position into the second position.

Description

technical field [0001] The invention proceeds from an overload protection assembly for protecting an overvoltage protection component, the overload protection component comprising at least one overvoltage protection component, two for connecting the overvoltage protection component to a current- or signal to be protected A coupling element on the path, a support with a current conducting element and at least one actuator. Wherein, the first coupling element comprises a heat-sensitive contact element. In the first position, the at least one overvoltage protection component is connected with its first pole to the carrier via the thermal contact element in such a way that an electrical connection to the circuit to be protected is established via the thermal element. Furthermore, the second pole of the overvoltage protection element is connected to the current-carrying element of the support via a second coupling element. In the event of a thermal overload of the overvoltage pro...
