Description
Es sind Elektrodenplatten für elektrische Sammler bekannt, die aus einem weitmaschigen Gitter aus Hartblei bestehen, dessen Felder durch Teilplatten ausgefüllt sind. Insbesondere in dem Fall, daß die Teilplatten aus Großoberflächenplatten bestehen, zeigen derartige Elektroden den Nachteil, sich zu krümmen. Das verhältnismäßig weitmaschige Gitter kann nämlich nicht so stark dimensioniert werden, um ein Krümmen oder Wachsen der Gesamtplatte zu verhindern.There are known electrode plates for electrical collectors, which consist of a wide-meshed Grids are made of hard lead, the fields of which are filled with partial plates. In particular in the event that the sub-panels consist of large-surface panels such electrodes have the disadvantage of curving. The relatively wide-meshed one Lattice cannot be dimensioned so strongly to avoid bending or To prevent the overall plate from growing.
Bei der Elektrode für galvanische Elemente, insbesondere als Großoberflächenplatte für elektrische Bleisammler, nach der Erfindung wird dieser Nachteil dadurch vermieden, daß eine Vielzahl von_ Teilplatten nach Patent 601 427 in an sich bekannter Weise mittels eines Rahmen- oder Gitterwerkes aus Hartblei zu einer großen Platte verbunden ist. Bei den Teilplatten nach dem Patent 601 427 mit sich kreuzenden Rippen und- zwischen den Rippen liegenden Zähnen besitzen die Zähne an ihren Schneiden Aussparungen in Form von Schlitzen, die nicht bis zur ganzen Plattenstärke durchgehen, so daß der Verband der sich kreuzenden Rippen bestehen bleibt. Auf Grund dieser Aussparungen ist die Ausdehnung der Einzelplättchen so gering, daß das Hartbleirahmen- und Gitterwerk dieser Ausdehnung standhält und ein Wachsen und Krümmen der Gesamtplatte mit Sicherheit vermieden bleibt. Die Elektrode nach der Erfindung zeichnet sich durch eine außerordentliche Festigkeit aus. Zur Herstellung der Elektroden gemäß der Erfindung werden zweckmäßig die Teilplatten bei ihrem Guß durch dünne Stege o. dgl. miteinander zu einer großen Platte verbunden, welche dann in die Gießform-für das Hartbleigitter- und Rahmenwerk eingelegt wird.In the case of the electrode for galvanic elements, especially as a large surface plate for electrical lead collector, according to the invention, this disadvantage is avoided in that a plurality of_ partial plates according to patent 601 427 in a manner known per se by means of a framework or latticework made of hard lead is connected to a large plate. at the partial plates according to patent 601 427 with intersecting ribs and between the Teeth lying on the ribs have recesses in the shape of the teeth at their cutting edges of slots that do not go through to the entire plate thickness, so that the association of the crossing ribs remains. The expansion is due to these recesses the individual platelets so small that the hard lead frame and latticework of this extent withstands and a waxing and warping of the entire plate is avoided with certainty. The electrode after the Invention is characterized by an extraordinary strength. For the production of the electrodes according to the invention are expediently the partial plates during their casting by thin webs or the like. Connected to one another to form a large plate, which then is inserted into the mold for the hard lead grid and framework.
Die Zeichnung zeigt ein Ausführungsbeispiel der Elektrode nach der Erfindung. Wie ersichtlich, besteht die Elektrode aus einer Vielzahl von Teilplatten t mit sich kreuzenden Rippen und zwischen den Rippen liegenden Zähnen. Die Teilplatten t sind mittels eines Rahmen- oder Gitterwerkes e aus Hartblei zu einer großen Platte verbunden. Die Zähne besitzen an ihren Schneiden Aussparungen in Form von Schlitzen, die nicht bis zur ganzen Plattenstärke durchgehen, so daß der Verband der sich kreuzenden Rippen bestehen bleibt.The drawing shows an embodiment of the electrode according to the invention. As can be seen, the electrode consists of a plurality of sub-plates t with intersecting ribs and teeth lying between the ribs. The partial plates t are connected to a large plate by means of a frame or lattice work e made of hard lead. The teeth have recesses in the form of slots on their cutting edges which do not go through to the entire thickness of the plate, so that the association of the intersecting ribs remains.
Zur Herstellung der Elektrode nach der Erfindung werden zweckmäßig die Teilpla,tten t bei ihrem Guß durch dünne Stege f (punktiert angedeutet) zu einer großen Platte miteinander verbunden, welche dann in die Gießform für das Rahmenwerk aus Hartblei eingelegt wird.In order to produce the electrode according to the invention, it is expedient for the partial plates t to be connected to one another during their casting by thin webs f (indicated by dotted lines) to form a large plate, which is then placed in the casting mold for the hard lead framework.
