Description

Hochohmiger Widerstandskörper Die Erfindung bezieht sich auf hochohmige Widerstandskörper, auf. dessen eines oder beide Enden längsgeschlitzte Metallrohre geschoben sind und bei denen über diesen Metallrohren noch besondere Metallkappen angebracht werden.High resistance body The invention relates to high resistance Resistance body, on. one or both ends of which are longitudinally slotted metal tubes are pushed and where over these metal tubes there are still special metal caps be attached.

Die Erfindung bezweckt, Widerstandskörper dieser Art so auszubilden, daß die Metallkappen den hochohmigen Widerstandskörper besonders gut und sicher leitend berühren, und daß dieser Widerstandskörper zwischen kräftigen Kontaktfedern eingeklemmt werden kann.The aim of the invention is to design resistance bodies of this type in such a way that that the metal caps the high-ohmic resistance body particularly well and safely conductively touch, and that this resistance body between strong contact springs can be pinched.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt, und zwar zeigen: Abb. i die äußere Ansicht eines gemäß der Erfindung zwischen zwei kräftigen Klemmfedern eingespannten Widerstandskörpers und Abb.2 eine Einzelheit des Widerstandskörpers im vergrößerten Maßstabe.The drawing shows an exemplary embodiment of the subject matter of the invention shown, namely: Fig. i the external view of one according to the invention Resistance body clamped between two strong clamping springs and Fig.2 one Detail of the resistor body on an enlarged scale.

Auf einem Porzellansockel i sind zwei kräftige Kontaktfedern 2 und 3 mittels Schrauben 4. und 5 befestigt, die zugleich mit den Stromzuführungen verbunden werden können. Die Enden der Kontaktfedern 2 und 3 sind so umgebogen, daß sie zwischen sich einen hochohmigen Widerstandskörper 6 aufnehmen können und diesen unter nachgiebigem Druck festhalten können, wobei sie gleichzeitig als Stromzuführungen dienen. Der Widerstandskörper 6 ist an seinen beiden Enden von geschlitzten Metallröhrchen 7 umgeben, welche etwa in ihrer Mitte eine V-förmige Einschnürung 8 besitzen. Über diese Metallröhrchen 7 sind an sich bekannte Metallkappen 9 geschoben. Ferner ist auf dem Porzellansockel i ein Halter 12, angebracht, an welchem eine mit einem dritten Stromanschluß verbundene Kontaktfeder mittels eines Griffes schwenkbar befestigt ist. Diese Kontaktfeder steht in jeder Lage in leitender Berührung mit dem Widerstandskörper 6.On a porcelain base i are two strong contact springs 2 and 3 fastened by means of screws 4. and 5, which are also connected to the power supply lines can be. The ends of the contact springs 2 and 3 are bent so that they are between can accommodate a high-resistance body 6 and this under flexible Can hold pressure, where they also serve as power supplies. Of the Resistance body 6 is made up of slotted metal tubes 7 at both ends which have a V-shaped constriction 8 approximately in their middle. Above these metal tubes 7 are fitted with metal caps 9 known per se. Furthermore is on the porcelain base i a holder 12, attached to which one with a third Power connection connected contact spring pivotally attached by means of a handle is. This contact spring is in conductive contact with the resistance body in every position 6th

Da die Metallröhrchen 7 mit einem Längsschlitz versehen sind, so sucht das Ende des Widerstandskörpers 6, wenn es beim Einschieben in das Metallröhrchen 7 gegen die V-förmige Einschnürung stößt, das Metallrohr 7 auseinanderzuspreizen. Infolgedessen legt sich dieses unter kräftigem Druck gegen die Innenwandung der Metallkappe 9, während gleichzeitig das Ende des Widerstandskörpers 6 infolge der Einschnürung 8 mit der Innenwandung des Rohres 7 in guter leitender Berührung steht. Es entsteht also auf diese Art eine besonders innige und gut leitende Verbindung des Widerstandsstabes 6 mit der oder den Metallkappen 9, ohne daß hierzu verwickelte Einrichtungen oder Schraubverbindungen erforderlich sind.Since the metal tubes 7 are provided with a longitudinal slot, seeks the end of the resistance body 6 when it is pushed into the metal tube 7 pushes against the V-shaped constriction to spread the metal tube 7 apart. As a result, this lays itself under strong pressure against the inner wall of the Metal cap 9, while at the same time the end of the resistor body 6 as a result of Constriction 8 is in good conductive contact with the inner wall of the tube 7. In this way, a particularly intimate and well-conducting connection is created of the resistance rod 6 with the metal cap or caps 9 without being entangled Facilities or screw connections are required.
