Description

Die Erfindung betrifft insbesondere lange Kohlelamellen mit metallischem Anschlußstück für Kollektoren elektrischer, Maschinen oder Apparate. Es wurde bereits vorgeschlagen, diese Anschlußstücke über die ganze axiale Länge der Lamellen zu erstrecken, wobei Metallfolien oder Metallgewebe in längs der axialen Länge sich erstreckenden Aussparungen an der Kohlelamelle vorgesehen sind, die zum Anschluß der Wicklungsdrähte dienen. Man kann dabei die Anschlußstücke an einer oder beiden Längsseiten der Lamelle anordnen. Die Erfindung bezieht sich auf die elektrisch gut leitende Verbindung des zweckmäßig als starre metallische Schiene ausgebildeten Anschlußstückes mit der Kohlelamelle. Erfindungsgemäß ist das Anschlußstück mit der verkupferten Kohlelamelle durch Lötung verbunden. Durch die Verlötung des Anschlußstückes mit der Kupferschicht an der Oberfläche der Lamelle wird über die ganze Länge des Anschlußstückes ein sehr geringer Übergangswiderstand zwischen diesem und der Kohlelamelle hergestellt, so daß der Stromübergang zu der Kohlelamelle über das ganze Ansehlußstück gleichmäßig verteilt vor sich geht.The invention particularly relates to long carbon lamellas with metallic Connection piece for collectors of electrical, machines or apparatus. It was already suggested that these connectors over the entire axial length of the lamellae extend, with metal foils or metal mesh in along the axial length Extending recesses are provided on the carbon lamella for connection serve the winding wires. You can use the connectors on one or both Arrange the long sides of the slat. The invention relates to the electrical highly conductive connection of the suitably designed as a rigid metallic rail Connection piece with the carbon lamella. According to the invention, the connector is with the copper-plated carbon lamella connected by soldering. By soldering the connector with the copper layer on the surface of the lamella is over the entire length of the Connection piece has a very low contact resistance between this and the carbon lamella made so that the current transition to the coal lamella over the entire connection piece is evenly distributed.

In den Fig. z und 2 der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Die für den Kollektor einer elektrischen Maschine bestimmten Lamellen r bestehen aus Kohle. Zur Stromführung sind metallische Schienen 2 vorgesehen, die an den Längsseiten der Lamellen in Ausnehmungen 3 angeordnet sind. Die 'Kohlelamellen sind mindestens an der Stelle der Ausnehmungen in bekannter Weise verkupfert, um einen besseren Stromübergang zu schaffen. Die Schienen sind mit den Lamellen durch Lötung fest verbunden.In Figs. Z and 2 of the drawing, an embodiment of the Invention shown. Those intended for the collector of an electrical machine Lamellae r are made of carbon. Metallic rails 2 are provided for conducting current, which are arranged in recesses 3 on the longitudinal sides of the slats. The 'charcoal lamellas are copper-plated in a known manner at least at the point of the recesses in order to create a better flow transition. The rails are through with the slats Solder firmly connected.
