  Abschaltkohlebürsten und Verfahren zu ihrer Herstellung 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 eingestampften Kupferpulverpfropfen 8 leitend mit der Bürste 1 verbunden, der gleichzeitig die unter dem Deckplättchen 6 voll gespannte Abschaltfeder 5 sichert. Am oberen Teil der Abschaltkohlebürste 1 sind Schultern 9 ausgebildet, auf die sich eine in der Federkappe 10 gehaltene Druckfeder 11 abstützt. 



    PATENTANSPRÜCHE :    
1. Abschaltkohlebürsten mit Aussparungen für die Abschaltmittel, dadurch gekennzeichnet, dass ein Isolierstoffkörper mit Abschaltfeder und ein Deckplättchen durch ein Einstampfmittel fest in der Kohle-   bürste   verankert sind.

 <Desc / Clms Page number 2>

 The crushed copper powder plug 8 is conductively connected to the brush 1, which at the same time secures the shut-off spring 5 fully tensioned under the cover plate 6. Shoulders 9, on which a compression spring 11 held in the spring cap 10 is supported, are formed on the upper part of the switch-off carbon brush 1.



    PATENT CLAIMS:
1. Switch-off carbon brushes with recesses for the switch-off means, characterized in that an insulating body with a switch-off spring and a cover plate are firmly anchored in the carbon brush by a ramming agent.

Claims (1)

2. Abschaltkohlebürsten nach Anspruch l, dadurch gekennzeichnet, dass von dem die Abschaltvorrichtung verankernden Einstampfmittel ein Stromzuführungskabel in der Kohlebürste gehalten und leitend mit der Bürste verbunden ist. 2. Switch-off carbon brushes according to claim l, characterized in that a power supply cable is held in the carbon brush by the crushing means anchoring the switch-off device and is conductively connected to the brush. 3. Abschaltkohlebürste nach den Ansprüchen 1 und 2, dadurch gekennzeichnet, dass das zwischen der Abschaltfeder und der Kabeleinstampfmasse eingebrachte Deckplättchen ein geringes Übermass gegenüber dem Durchmesser der Bürstenbohrung aufweist. 3. switch-off carbon brush according to claims 1 and 2, characterized in that the cover plate introduced between the switch-off spring and the cable ramming compound has a slight excess relative to the diameter of the brush bore. 4. Verfahren zur Herstellung von Abschaltkohlebürsten nach den Ansprüchen 1 bis 3, dadurch gekennzeichnet, dass die zusammen mit dem Isolierstoffkörper in die Kohlebürste eingebrachte Abschaltfeder mit dem Deckplättchen durch einen Stempel eingepresst, dabei vorgespannt und durch das Einstampfen von Kupferpulver allein oder zusammen mit einem Stromkabel auf volle Spannung gebracht und durch den entstandenen Kupferpulverpfropfen gesichert und dieser durch einen Lacküberzug versiegelt wird. 4. Process for the production of switch-off carbon brushes according to claims 1 to 3, characterized in that the switch-off spring, which is introduced into the carbon brush together with the insulating body, is pressed in with the cover plate by a punch, thereby pretensioned and by the tamping of copper powder alone or together with a power cable brought to full tension and secured by the resulting copper powder plug and this is sealed by a lacquer coating.
