Device socket

The invention relates to an appliance socket such as that used, for example, for electric kettles, bread toasters, irons and the like. is applied.

Such sockets are well known. Often, however, a socket is required that apart from the normal power supply function can fulfill other functions. In particular, a thermostat effect or a temperature safety effect can be used here be thought. Individual thermostats and temperature safety devices are known. These are often in the electricity supply Device built-in, which has the disadvantage, among other things, that the device often only works if the thermostat or the temperature fuse is defective difficult or impossible to repair.

With the invention, a socket is now intended with which the im the disadvantages indicated above can be eliminated. To this end

a socket of the type described is characterized according to the invention by a thermostat arranged in the housing, which is provided with a temperature sensor protruding from the housing and between the one contact socket and a feeder is connected, and by a thermal fuse that is in the connection is arranged between the thermostat and the one contact socket and the connection between the thermostat and the one contact socket interrupt if a temperature occurs that exceeds the temperature control range of the thermostat.

The invention will now be described in more detail with reference to the drawing of an exemplary embodiment.

Ss show:

Fig. 1 is a broken plan view of an inventive Socket and

FIG. 2 shows a cross section of the socket of FIG. 1.

The figures show a housing 1 made, for example, of Bakelite can be and is provided with contact sockets 2 and 3, which are fastened in the usual way in the housing. Three conductors 5> 6.7 are inserted into the housing via a grommet 4. The head is directly connected to the contact socket 3. The conductor 6 is connected to a connection point 8 of a controllable thermostat element 9. A second connection point 10 of the thermostat 9 is via a short conductor 11 connected to the contact socket 2. The third conductor 7 is a conventional protective contact conductor.

The thermostatic element 9 contains a sensor 20 and a control button 21, by means of a screwable pin 22, the distance between a pair of interrupter contacts 23 and one by bimetallic action of the sensor 20 movable interrupt arm 24 adjustable is. The contacts 23a and 23b of the breaker contact pair touch each other when the sensor 20 is cold, are connected to the connection points 8 and 10 and thus form one in the rest position electrical connection between conductor 6 and conductor 11.

When the probe 20 is heated, the arm 24 is moved upwards and
the contact 23b will be lifted from the contact 23a at a temperature determined by the position of the control button 21. the
The connection between the conductor 6 and the contact socket 2 is then interrupted. The temperature of the sensor 20 then decreases until the arm 24 is moved so far down that the contact 23b the
Contact 23a touched again. This process can then be repeated so that the temperature of the sensor, and thus that in the device, is kept within certain limits.

To further secure the device, a known temperature fuse 30 is also provided, which is connected between the contact socket 2 and the conductor 11. If the thermostat does not switch off the power in time, the temperature fuse is the connection between the contact socket 2 and your leader 11
interrupt so that the circuit is permanently interrupted.

Finally, a neon lamp 31 is also provided to make it visible to make whether the circuit is interrupted or not.
