Thermal switching device, heating arrangement, as well as procedure for mounting a thermal switching device in a heating device

摘要

Thermal switching device, in particular temperature regulator, temperature limiter, temperature controller or over temperature protector, for the connection that is in thermal contact with a utility object comprising a heating device, with a support (2) having thermally conductive fixing tabs (5, 6), preferably plate-shaped, by means of which the switching device (1) can be mounted in thermal contact with the utility object, a functional element that reacts to temperature, preferably a bimetallic element (21) or a molten element (24), to ensure a temperature-dependent switching function of the thermal switching device (1), as well as contact connectors (4a, 4b) for the connection of the thermal switching device (1) to sections of electrical wiring, the support (2) being able to be joined by laser welding in the area of its fixing nipples (5, 6) with the utility object that is in thermal contact, characterized in that the lower sides of the plate-shaped support (2) and its fixing tabs (5, 6) are configured flat and are placed in the same plane and the fixing tabs (5, 6) of the support (2) have an area (8) specially prepared for the coupling of a laser beam (10) such that the area (8) comprises a contour and / or structuring the surface of the fixing tabs (5, 6) of the support (2) which reduces the cross section towards the lower side of the support (2).
