Device for thermally tripping or disconnecting an overvoltage protection device

A device for thermally tripping or disconnecting an overvoltage protection device, comprising:

• a locking element (A1) on which a first force (F1) acts and which is fixed to the device in such a way that said locking element is released when a limit temperature is exceeded, wherein the temperature-dependent fixing of the locking element (A1) is realised by a solder connection, an adhesive and/or by a wax connection;
• a slider (S1) which is blocked in a first state (Z1) by the fixed locking element (A1), and on which a second force (Z2) acts in order to transfer said slide to a second state (Z2) when the locking element (A1) is released;
• characterized by
• a latching-holding device (H1) which is connected to the slider (S1) and by means of which the locking element (A1), which is configured as an electrical component and is fixed to a circuit board, blocks the slider indirectly and by means of which the second force (F2) only acts as a partial force component in a frictionally engaged clamping manner on the locking element (A1), wherein the latching-holding device (H1) comprises at least two elastic, resilient jaws (B) which are supported in the first state (Z1) against the fixed locking element (A1) and against a surrounding area (G) of the slider (S1), the jaws (B) further each comprising an outwardly directed groove for accommodating one cam (H2) each, the second force (F2) being redirected by the cams (H2) onto the jaws (B) in order to press the jaws (B) inwardly.
