- FIG. 1 shows an embodiment of a heating device according to the invention 11 shown in section. This is just like the other figures Drawing to understand schematically and is intended to serve the principle of the invention to explain in different versions.
- a ceramic carrier 12 has a plurality of heating conductors on its upper side 16 13 on.
- the heating conductor 13 can run in any path as it is known per se from the prior art. For example, you can be applied in thick film technology.
- the heating conductor 13 and a the surrounding area of the top 16 of the ceramic carrier 12 is with insulation 14. This can be a layer of glass, for example or the like.
- the insulation 14 of the heating conductor 13 has the top The advantage that electrical insulation is ensured on the one hand.
- the insulation 14 can also be used in a Heating device 11 in a kettle or similar device, which directly in with food or other media Can come into contact, shield the heating conductor 13.
- a fuse 18 On an underside 17 of the ceramic carrier 12 is a fuse 18, in in this case a thermal fuse according to the present invention, appropriate.
- the fuse 18 has two spaced solder contacts 19, which are applied to the underside 17.
- the solder contacts 19 in turn have contact leads 20.
- the electrical line over the contact lead 20 should be secured with the fuse 18 and be interrupted in an emergency.
- a connecting bridge 22 is provided on the solder contacts 19. This is soldered to the solder contacts 19 with solder. It connects the Contact leads 20.
- the connecting bridge is in a very simple design 22 made of conductive, in particular easily solderable, metal manufactured.
- the heating device 11 or the ceramic carrier 12 become too hot, for example due to excessive power consumption of the heating plate 13 or for example, boiling empty a kettle with insufficient Heat dissipation, so also the solder contacts 19. To for this purpose, as shown in Fig. 1, they can be directly opposite a heating conductor 13 and only separated by the ceramic support 12.
- the heating of the solder contacts 19 causes a certain amount a softening of the solder with which the connecting bridge 22 is fastened is.
- the connecting bridge can then be used with the solder softened 22 pulled down by gravity, i.e. from the solder contacts 19 away. If the contact leads 20 in the Energy supply for the heating conductor 13 are, the heating conductor of separated from the energy supply. This corresponds to the basic principle a thermal fuse with interruption.
- the heating device 11 approximately as in FIG 1 is installed.
- FIG. 2 shows a further embodiment of the invention with a heating device 111 shown. This can also on an underside 117 of an insulating Carrier are arranged.
- the illustration in Fig. 2 is one Top view, for example from below.
- An elongated heating conductor 113 is provided. This is on his right end via a connection field 125 with a contact lead 120 connected. This lower contact lead 120 opens into a solder contact 119. Another solder contact is on the other side of the heating conductor 113 119 arranged in the form of a field. This is again with one Contact lead 120 connected, which for example to a power supply is led.
- solder contacts 119 122 There is a connecting bridge between the solder contacts 119 122. It is advantageously soldered to the solder contacts 119, as before has been described. Alternatively, gluing would be possible.
- solder with a precisely defined melting point is preferred as the solder used. This melting point or a resulting softening result in connection with the weight of the connecting bridge or their necessary holding force in the installed state Tripping temperature of the fuse used as a thermal fuse 18th
- the heating conductor 113 can be supplied with electrical energy. Since the connecting bridge 122 crosses the heating conductor 113, there is in between an insulating layer 124 is provided.
- it can be glass or ceramic.
- a connecting bridge 122 can also be used, at least in the area in which they are Heating conductor 113 bridges, is itself electrically isolated.
- a simple connection bridge Metal piece can be used. It is also possible to use an electric conductive material with a precisely defined or desired Select conductivity. This can have the consequence that the Current flow for energy supply to the heating conductor via the connecting bridge the connecting bridge has already been preheated to a certain temperature becomes. This temperature then prevails approximately at the Solder contacts. This allows the fuse to trip even faster with preheated solder and faster reaching of the softening point can be achieved.
- FIG. 4 is a third embodiment of a heating device according to the invention 211 shown with a fuse 218.
- heating conductors 213 intended. While the explanations according to Figures 1 to 3 each provide the connecting bridge in the supply line to the heating conductor, can with this version the fuse or the connection to Bridge can be provided in the course of the heating conductor itself. This would be with simple modification also in the embodiments according to the figures 1 to 3 possible.
- connection fields 225 The ends of the heating conductors 213 are connected to connection fields 225. These are in turn connected to solder contacts 219 via contact lead 220 connected or made in one piece. At the solder contacts 219 attached a connecting bridge 222 by solder.
- This special embodiment of the connecting bridge 222 is approximately reversed U-shaped. Legs 228 extend from a base 227. The Ends of the legs 228, opposite the base 227 are with the Solder contacts 219 soldered. Taking into account that the device 4 is installed upside down, ie with the underside 217 downwards, the following advantages result from such a training of Connection bridge 222.
- solder that connects the connecting bridge 222 to the solder contacts 219 connects, soft, in principle it dissolves and does not become absolutely liquid, but at least viscous. However, this still means not automatically that the connecting bridge by gravity drops.
- the adhesive force of the softened liquid solder can do this, similar to what would be the case with a drop of water.
- a straight connecting bridge 122 as shown, for example, in FIG. 2 if it is not difficult enough, it could still be sent to the Adhere solder contacts 119. It would even be about the liquid solder given the electrical connection.
- connection bridge As an alternative to a U-shaped connection bridge, for example can be provided that this is simple on one side passed over the line between the solder contacts. It so it almost depends on the center of gravity of the connecting bridge lies outside the connecting line between the solder contacts.
- Design options can be the carrier 12, the type and Form of the heating conductor 13, the type of electrical interconnection with the fuse 18, the solder contacts 19 and the shape of the connecting bridge 22 and their connection to the solder contacts 19 relate.
- conductive adhesives which is also the Have softening properties at a certain temperature, possible.
