Gegenstand der vorliegenden Erfindung ist ein Akkumulator mit Wickelelektroden nach dem Hauptpatent 1233 040.The present invention relates to an accumulator with wound electrodes according to the main patent 1233 040.
Bei diesem Akkumulator sind die beiden Polableiter an den Stirnseiten des Elektrodenwickels angeschlossen. Die wesentlichen Merkmale des Akkumulators nach der Hauptanmeldung bestehen darin, daß sowohl die positive Elektrode 1 als auch die negative Elektrode 2 in ihrer ganzen Länge einen keine aktive Masse enthaltenden massivmetallenen Rand besitzen, so daß der Rand 4 der positiven Elektrode 1 an der einen Stirnseite des Elektrodenwickels über, den negativen Wickel hinausragt, während der Rand 5 der negativen Elektrode 2 an der entgegengesetzten Stirnseite des Elektrodenwickels über den positiven Wickel hinausragt, und daß ferner jeder der Ränder 4. 5 großflächig mit dem entsprechenden Polableiter 7, 8 verbunden ist. Jeder der Ränder 4, 5 kann in seinem spiraligen Verlauf an mehreren Stellen mit gegenüberliegenden Stellen seiner benachbarten Windüngen verschweißt sein. Die großflächige Verbindung zwischen dem Polabieiter und den an den Stirnseiten des Elektrodenwickels herausragenden Rändern wird dadurch erreicht, daß der Polabieiter mit einer Polscheibe versehen ist, die mit den Rändern verbunden wird.In this accumulator, the two pole conductors are connected to the end faces of the electrode coil. The main features of the accumulator according to the main application are: that both the positive electrode 1 and the negative electrode 2 in their entire length one have no active mass containing solid metal edge, so that the edge 4 of the positive electrode 1 on one end face of the electrode coil, the negative coil protrudes, while the Edge 5 of the negative electrode 2 on the opposite end of the electrode coil over the positive winding protrudes, and that each of the edges 4. 5 over a large area with the corresponding pole conductor 7, 8 is connected. Each of the edges 4, 5 can with its spiral course in several places opposite points of its neighboring turns be welded. The large-area connection between the Polabieiter and those on the front sides of the electrode coil protruding edges is achieved in that the Polabieiter with a Pole disc is provided, which is connected to the edges.
Als besonders vorteilhaft hat sich nun erwiesen, die Polscheibe mit zu den Rändern hin vorstehenden Sikken zu versehen und durch Stumpfschweißung mit den vorstehenden spiraligen Metallrändern zu verbinden. It has now proven to be particularly advantageous to have the pole disc with crenels protruding towards the edges to be provided and connected to the protruding spiral metal edges by butt welding.
Eine bevorzugte Ausführungsform der erfindungsgemäßen Polscheibe ist in der F i g. 3 näher dargestellt.
Die Sicken 9, angebracht auf einer relativ großen Fläche, gewährleisten eine definierte Stromverteilung
beim Schweißen, wodurch die Schweißung exakt auf die gewünschten Punkte erfolgt und eine
unkontrollierbare Verschweißung des spiraligen Bandes vermieden wird. Besonders bei hoher Strombelastung
bringt diese zusätzliche Verschweißung an den zusammengeschweißten Stellen des spiraligen
Elektrodenbandes den Vorzug einer besonders guten elektrisch leitenden Verbindung. Die Verschweißung
der im Wickel gegenüberliegenden Ränder gleicher Polarität, wie sie zur Verkürzung der Stromwege oft
angewendet wird, kann unterbleiben, ohne daß dabei die Qualität der Verbindung und die Stromableitung

Akkumulator mit WickelelektrodenA preferred embodiment of the pole disk according to the invention is shown in FIG. 3 shown in more detail. The beads 9, attached to a relatively large area, ensure a defined current distribution during welding, whereby the welding takes place exactly on the desired points and uncontrollable welding of the spiral band is avoided. Particularly when there is a high current load, this additional welding at the welded-together points of the spiral electrode strip has the advantage of a particularly good electrically conductive connection. The welding of the opposite edges of the same polarity in the coil, as is often used to shorten the current paths, can be omitted without affecting the quality of the connection and the current conduction.

benachteiligt werden. Durch die erfindungsgemäßen Sicken wird die Herstellung der Akkumulatoren nach der Hauptanmeldung unter Erhöhung ihrer Leistungsfähigkeit erheblich vereinfacht.be disadvantaged. Due to the beads according to the invention, the manufacture of the accumulators is improved the main application is simplified considerably while increasing its performance.
Tn den F i g. 2 und 3 sind 4 Sicken eingezeichnet, die in einem Winkel von 90° angeordnet sind. Die Sicken kommen auf die zusammengefaßten umlaufenden Elektroden ränder zu liegen und ergeben einen einwandfreien Kontakt bei dem vorgesehenen Schweißvorgang. Die Zahl und Anordnung der Sicken kann variiert werden. Über der Polscheibe liegt vorteilhafterweise ein Kunststoffring, der in der Mitte für die Polableitung eine Ausnehmung besitzt, damit die Zelle besser gegen Kurzschluß gesichert ist.Tn the F i g. 2 and 3 4 beads are shown, which are arranged at an angle of 90 °. the Corrugations come to lie on the combined circumferential electrode edges and result in one perfect contact during the intended welding process. The number and arrangement of the beads can be varied. A plastic ring is advantageously located above the pole disc, which is in the middle has a recess for the pole derivation so that the cell is better protected against short circuits.
Die Schweißung erfolgt ähnlich wie bei der bekannten Doppelpunktschweißung, bei der beide Schweißelektroden auf dem Deckel liegen und der Stromfluß unter dem erforderlichen Kontaktdruck ausgelöst wird.The welding is carried out in a similar way to the well-known double-spot welding, in which both Welding electrodes are on the lid and the current flow is below the required contact pressure is triggered.
