 Verbindung zwischen Schelle und Silitstab herstellen, ergibt sich der Vorteil, dass einerseits der Stab bei   seinem Festklemmen zwischen denbeiden Schellenhälftennicht   so leicht bricht und anderseits eine genügend grosse Kontaktfläche gewährleistet ist, um eine übermässige Erhitzung beim Übergang des Stromes von der Schelle auf den Stab zu vermeiden. Ferner gestattet eine derartige federnde Verbindung eine leichte

Wärmeausstrahlung. Es ist daher eine übermässige Erhitzung der Kontaktstelle zwischen Fassung und
Silitstab nicht zu befürchten.

   Ferner kann der Stab, ohne allzustark beansprucht zu werden, sich leicht ausdehnen und auch bei der Montage etwas von seiner axialen Lage abgebogen werden. Es ergibt sich hieraus ein zuverlässiger Betrieb ohne vorzeitigen Verbrauch der Widerstände durch Bruch od. dgl.

 Establishing a connection between the clamp and the silicone rod results in the advantage that, on the one hand, the rod does not break so easily when it is clamped between the two halves of the clamp and, on the other hand, a sufficiently large contact surface is guaranteed to avoid excessive heating when the current passes from the clamp to the rod . Furthermore, such a resilient connection allows easy

Heat radiation. It is therefore an excessive heating of the contact point between the socket and
Silitstab not to fear.

   Furthermore, the rod can easily expand without being excessively stressed and can also be bent slightly from its axial position during assembly. This results in reliable operation without premature consumption of the resistors due to breakage or the like.



   Causes and a convenient assembly.
