Description

Elektrisch abgeschirmter Drehschalter-Meßwiderstand Das Gebrauchsmuster betrifft einen Drehschalter-Meßwiderstand mit einer mit der Achse verbundenen kreisförmigen Nummernscheibe 0 zur Bezeichnung der Widerstandsstufen und gegebenenfalls einer 0 CD ein Schauloch tragenden Abdeckung derselben. Nach dem Gebrauchsmuster ist die Nummernscheibe selbst oder ihre Abdeckung aus elektrisch leitendem Stoff, zweckmäßig Metall hergestellt und so ausgebildet, insbesondere so groß gewählt, daß die der Kurbel zugeordneten Widerstandselemente gegen kapazitiven Einfluß der bedienenden Hand elektrisch abgeschirmt ist. Dies ist von großer Bedeutung für die Anwendung von Drehschalter-Meßwiderständen bei empfindlichen elektrostatischen Messungen oder in Hochfrequenzkreisen.Electrically shielded rotary switch measuring resistor The utility model relates to a rotary switch measuring resistor with a circular dial connected to the axle 0 to designate the resistance levels and, if applicable, one 0 CD a peephole carrying cover of the same. According to the utility model, the dial itself or its cover is made of electrically conductive material, suitably metal, and designed, in particular chosen so large that the resistance elements associated with the crank are electrically shielded against the capacitive influence of the operating hand. This is of great importance for the use of rotary switch measuring resistors in sensitive electrostatic measurements or in high frequency circuits.

Der Abschirmungsschutz wird nach einer Weiterausbildung nach dem Gebrauchsmuster noch vervollkommnet, wenn das die Widerstandselemente umschließende Gehäuse mit einem leitenden Belag ausgekleidet ist, der zweckmäßig mit dem unter dem Drehknauf angebrachten Abschirmungsschutz leitend verbunden ist.The shielding protection becomes after further training according to the utility model even more perfect when the housing enclosing the resistor elements with a conductive covering is lined, which is useful with the under the rotary knob attached shielding protection is conductively connected.

Abbildung 1 zeigt eine Ausführungsform, bei der die mit der Kontaktfeder zusammen drehbar angeordnete Nummernscheibe N selbst aus Metall besteht und den Abschirmungsschutz gegen das Innere des Gehäuses bildet. Das Gehäuse G ist mit eihem elektrisch leitenden - Belag E ausgekleidet. Abbildung 2 zeigt eine Ausführungsform bei der die Abschirmung durch C> die nicht mit der Kontaktfeder zusammen drehbare aus Metall bestehende Abdeckung C gebildet ist. Unter der Abdeckung e befindet sich, mit der Kontaktfeder K bezw. deren Welle fest verbunden, die Nummernscheibe N, die durch das Schauloch in der Abdeckung beobachtet werden kann..Figure 1 shows an embodiment in which the dial N rotatably arranged together with the contact spring itself consists of metal and forms the shielding protection against the interior of the housing. The housing G is lined with an electrically conductive coating E. Figure 2 shows an embodiment in which the shielding by C> the cover C made of metal and rotatable together with the contact spring is formed. Under the cover e is, respectively, with the contact spring K. whose shaft is firmly connected, the dial N, which can be observed through the peephole in the cover ..
