Abstract
The invention is directed to a protective device for a heating unit, in particular for a flow-through heater (,), which is equipped with a current-carrying conductor (,) having a first end thereof mechanically biased into contact with a first fixed point of connection (,) and a second end (,) thereof soldered to a second point of connection (,). In the event of an error condition due to overheating, the bias operates to move the conductor (,) away from the second point of connection (,), severing the soldered joint in the process, whereby the circuit is opened. According to the present invention, the point of connection (,) is formed by a terminal stud (,), and the end (,) of the conductor (,) needing to be soldered to the terminal stud (,) is shaped in such manner that a sufficiently large soldered joint (,) requiring wetting by the solder (,) is developed. Even where thin wires are used, a particularly large-area and hence solid solder connection is thereby accomplished which has a better thermal effect on the soldered joint (,) and therefore enables a quicker acting protective device to be obtained.
