JVl 143697 KLASSE 21 c. JVl 143697 CLASS 21 c.

Vorliegende Erfindung besteht in einem Verfahren zur Herstellung von Widerstandselementen, bei denen eine Spirale aus Widerstandsmaterial in einer Röhre isoliert fest hineingepaßt und dann die Röhre mit einer schlecht leitenden Masse ausgefüllt wird, so daß nach Fertigstellung des Elements eine Lagenänderung der Spirale auch bei starker Beanspruchung durch den elektrischen Strom unmöglich wird. Hierbei können sowohl einfache glatte Röhren, wie auch gerippte Röhren, sowohl im ganzen, wie auch aufgeschlitzt oder aus mehreren ringförmigen Segmenten bestehend, verwendet werden.The present invention consists in a method for the production of resistance elements, in which a spiral made of resistance material is insulated and firmly fitted in a tube and then the tube is filled with a poorly conductive compound, so that after completion of the element Change of position of the spiral even when subjected to heavy loads from the electric current becomes impossible. Both simple smooth tubes and ribbed tubes, both as a whole as well as slit or consisting of several ring-shaped segments, be used.

Die Neuerung besteht in der Art, wie der Widerstandsdraht in die Röhre eingebracht wird. Und zwar wird hierzu die Federkraft der Widerstandsspirale selbst benutzt. Der Widerstandsdraht wird auf einen Dorn fest aufgewickelt; der Durchmesser des Domes ist so gewählt, daß er bewickelt, noch leicht in die innen mit einem Isoliermantel versehene Metallröhre hineingeht. Der Dorn wird mit der auf ihm festgespannten Spirale in die Röhre hineingeschoben. Werden dann die Enden der Spirale gelötet, so springt dieselbe wie eine Feder auf und preßt sich gegen die Wand der Röhre an. Der Dorn wird darauf herausgezogen und das Vollfüllen der Röhre mit schlecht leitendem Material kann in bekannter Weise erfolgen, ohne daß ein Verschieben der Spirale stattfinden kann.The innovation is the way in which the resistance wire is inserted into the tube will. The spring force of the resistance spiral itself is used for this purpose. Of the Resistance wire is tightly wound on a mandrel; is the diameter of the dome chosen so that it wraps, still slightly in the inside with an insulating jacket Metal tube goes inside. The mandrel with the spiral clamped on it is inserted into the Tube pushed in. If the ends of the spiral are then soldered, it will jump like a spring and presses itself against the wall of the tube. The thorn is on it pulled out and the full filling of the tube with poorly conductive material can be known in Wise done without a shifting of the spiral can take place.
