 widerstände, der aus Prägemasse hergestellt ist. Man erzielt dadurch die Möglichkeit, dem Widerstandsträger bei seiner Herstellung jede   gewünschte   Form geben und besonders auch, etwa später notwendige Metallteile gleich von vorneherein in las Material einpressen zu können. 



   Besonders günstig erweist sich ein   solcherart hergestellter Widerstandsträger   dann, wenn ein grösserer Körper von prismatischer Gestalt verwendet werden soll. Die bekannten Porzellan-, Glas-oder Tonröhren liessen sich bisher zu diesem Zwecke schlecht verwenden, da sie nicht

 Widerstandsdrahtes am Körper selbst dann, wenn der Draht eine   grosse   Länge hat. Eine Lockerung der Windungen bei der   Erwärmung,   wie es bei den zylindrischen Widerstandsträgern vorkommt, ist, bei den oben   genannten Trägern völlig   ausgeschlossen. 



   In der Zeichnung ist eine   Ausführungsform     des Widerstandsträgers   dargestellt, und zwar 
 EMI1.3 
 
Der   Widerstandsträger   a ist emindungsgemäss aus isolierender Prägemasse (wie z. B. Kunstholz u. dgl.) hergestelli, deren Zusammensetzung das Einpressen von Metallteilen gestattet. 



  Die besondere Form und Länge des Widerstandstragers ist zwar an und für sich belanglos, doch hat sich die aus Fig. 3 im Schnitte ersichtliche prismatische Gestalt mit   gewölbten Seitenflächen   sehr zweckmässig erwiesen, weil sie, wie bereits   früher @wähnt,   ein festes und sicheres Anlegen des Widerstandsdrahtesgestattet. 



   Bei den bekannten   Schieberwiderständen   verwendet man als Material für diese Seitenplatten Eisen oder   dgl.. so dass   dann die   Anschlussklemmen   und die Schieberstangen mittels Büchsen aus Isoliermaterial in diesen Seitenplatten befestigt werden   müssen.   Es werden dadurch 
 EMI1.4 
 ohne jegliche besondere Isolationsbüchsen oder Isolationsscheiben u. dgl. an diesen Seitenplatten zu befestigen. Das ist besonders in jenen Fällen vorteilhaft, wo mehrere Widerstandsträger zu   einem einzigen Widerstand vereinigt werden sollen. Ausserdem fallen auch besondere Befestigungs-   schrauben für die an den Seitenplatten anzubringenden Metallteile fort.

   Es darf   schliesslich nicht   ausser acht gelassen werden. dass auch eine Wärmeisolation nicht erforderlich ist. wie bei den   Schieberwiderständen, wo Metallrohre als Widerstandsträger verwendet werden.

 resistors made from stamping compound. This makes it possible to give the resistor carrier any desired shape during its manufacture and, in particular, to be able to press any metal parts required later into the material right from the start.



   A resistor carrier produced in this way proves to be particularly favorable when a larger body of prismatic shape is to be used. The known porcelain, glass or clay tubes have hitherto been difficult to use for this purpose because they are not

 Resistance wire on the body even if the wire has a great length. A loosening of the windings during heating, as occurs with the cylindrical resistance carriers, is completely excluded in the above-mentioned carriers.



   In the drawing, an embodiment of the resistor carrier is shown, namely
 EMI1.3
 
According to the invention, the resistor carrier a is made of insulating stamping material (such as synthetic wood and the like), the composition of which allows metal parts to be pressed in.



  The special shape and length of the resistance carrier is in and of itself irrelevant, but the prismatic shape with curved side surfaces that can be seen in section in Fig. 3 has proven to be very useful because, as already mentioned earlier, it ensures a firm and safe application of the Resistance wire allowed.



   In the known slide resistors, iron or the like is used as the material for these side plates, so that the connection terminals and the slide rods then have to be fastened in these side plates by means of bushes made of insulating material. It will be through it

 without any special insulation sleeves or washers etc. Like. To attach to these side plates. This is particularly advantageous in those cases where several resistor carriers are to be combined into a single resistor. In addition, special fastening screws for the metal parts to be attached to the side plates are also omitted.

   Ultimately, it must not be ignored. that thermal insulation is also not required. as with the slide resistors, where metal tubes are used as resistance carriers.
