Description

2525th

Die Erfindung betrifft eine flüssigkeitsdichte Verbindung eines Deckels aus thermoplastischem Material mit einem Kasten aus thermoplastischem Material für Akkumulatoren, bei der die Wände des Kastens im oberen Bereich eine Nut aufweisen, der in eine Nut des Deckels eingesetzt ist, und in den so entstehenden Hohlraum ein Kunststoff eingespritzt ist.The invention relates to a liquid-tight connection of a lid made of thermoplastic material with a box made of thermoplastic material for accumulators, in which the walls of the box in have a groove in the upper region, which is inserted into a groove in the cover, and into the groove that is created in this way A plastic is injected into the cavity.

Bei einer derartigen bekannten Verbindung eines Deckels mit einem Kasten aus thermoplastischem Kunststoff (DT-OS 14 25 439) müssen die Kastenwände verhältnismäßig dick ausgeführt sein, weil die Nuten in den Oberseiten der Kastenwände nicht zu eng sein dürfen; bei zu engen Nuten ist nämlich der Reibungswiderstand zwischen Vergußmasse und Kanalwandung beim sogenannten Spritzschweißen so groß, daß die thermoplastische Vergußmasse die Nuten nicht auf ihrer ganzen Länge ausfüllt und bei zu hohem Einspritzdruck aus dem Kanal herausgequetscht wird.In such a known connection of a lid to a box made of thermoplastic Plastic (DT-OS 14 25 439), the box walls must be made relatively thick because the grooves in the tops of the box walls must not be too narrow; if the grooves are too narrow, there is frictional resistance between the potting compound and the channel wall in so-called spray welding so large that the thermoplastic potting compound does not fill the grooves over their entire length and if too high Injection pressure is squeezed out of the channel.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, eine Spritzschweiß"erbindung für Kasten und Deckel aus thermoplastischem Kunststoff zu entwikkeln, die aus Materialeinsparungsgründen dünnere Außen- und Zwischenwände zuläßt.In contrast, the object of the invention is to provide a spray welding connection for boxes and To develop thermoplastic plastic lids, which allows thinner outer and partition walls to save material.

Eine besonders gute Lösung ergibt sich, wenn gemäß der Erfindung die Deckelnut breiter ist als die Stärke der Kastenwände und innerhalb der Deckelnut ein Wulst vorgesehen ist, der die beim Aufsetzen des Deckels durch die Wandnut gebildeten Stege auseinanderspreizt. A particularly good solution is obtained if, according to the invention, the cover groove is wider than the thickness of the Box walls and a bead is provided within the lid groove, which when the lid is put on webs formed by the wall groove spreads apart.

In der Zeichnung ist ein Ausführungsbeispiel desIn the drawing is an embodiment of the

Erfindungsgegenstandes dargestellt, und zwar zeigtSubject of the invention shown, namely shows

F i g. 1 einen Abschnitt einer teilweise geschnittenen Akkumulatoren-Blockbatterie von der Seite mit einer erfindungsgemäßen Verbindung von Kasten und Dekkel. F i g. 1 shows a section of a partially sectioned accumulator block battery from the side with a connection of the box and lid according to the invention.

Fig.2 einen Querschnitt einer erfindungsgemäßen Verbindung in vergrößertem Maßstab,2 shows a cross-section of a connection according to the invention on an enlarged scale,

F i g. 3 einen Querschnitt durch den Verbindungsbereich, jedoch vor dem Aufspreizen der Stege an der Kastenwand-Oberseite, in vergrößertem Maßstab, undF i g. 3 shows a cross section through the connection area, but before the webs are spread apart on the Box wall top, on a larger scale, and

F i g. 4 einen Querschnitt durch den Verbindungsbereich, jedoch nach dem Aufspreizen der Stege an der Kastenwand-Oberseite, in vergrößertem Maßstab.F i g. 4 shows a cross section through the connection area, but after the webs on the FIG Box wall top, on an enlarged scale.

Der in F i g. 1 gezeichnete Akkumulator besteht aus einem Blockkasten 1 mit den Zellengefäßen 2, in denen sich je ein Plattenblock 3 und Elektrolyt befindet, aus dem Blockdeckel 4 mit den Verschlußstopfen 5 und den nicht dargestellten Zellenverbindern und Endpolen. Kasten 1 und Deckel 4 sind hierbei durch sogenanntes Spritzschweißen miteinander verbunden; unter Spritzschweißen versteht man das Einspritzen von thermoplastischem Kunststoff als Vergußmasse 8 in einen gemeinsam von Deckelnuten 9 und Kastenwandnuten 10 (Fig.3) gebildeten, durchgehend verlaufenden, in sich geschlossenen Kanal U (Fig.4) mit Hilfe einer Spritzgießmaschine.The in F i g. 1 drawn accumulator consists of a block box 1 with the cell vessels 2, in which there is a plate block 3 and electrolyte, from the block cover 4 with the plugs 5 and the cell connectors, not shown, and end poles. Box 1 and cover 4 are here by so-called Spray welding connected to each other; Injection welding is the injection of thermoplastic Plastic as a potting compound 8 in a joint of lid grooves 9 and box wall grooves 10 (Figure 3) formed, continuous, self-contained channel U (Figure 4) with the help of a Injection molding machine.

Die neue Spritzschweißverbindung zeichnet sich durch eine Preis- und Gewichtsersparnis aus, weil die Kastenwände 6, 7 dünner sind, als es bei der bekannten Spritzschweißverbindung möglich ist. Bei dem gezeichneten Ausführungsbeispiel sind die Kastenwände 6, 7 1,5 mm dick und haben an ihren Oberseiten eine Nute 10, deren Seitenwände als lippenartige Stege 12 in die Deckelnute 9 hineinragen. Dabei ist die Deckelnute 9 wesentlich breiter als die Kastenwände 6, 7 dick sind. Etwa in Bodenmitte innerhalb der Deckelnute 9 steht ein Wulst 13 vor, der die Stege 12 der Kastenwände 6,7 anläßlich des Zusammensetzen von Kasten 1 und Deckel 4 auseinanderspreizt. Einspritzöffnungen 15 für die thermoplastische Vergußmasse 8 führen durch den Wulst 13 im Deckel 4 in den Spritzschweißkanal 11.The new spray welding connection is characterized by a price and weight saving, because the Box walls 6, 7 are thinner than is possible with the known spray-welded connection. With the one drawn In the exemplary embodiment, the box walls 6, 7 are 1.5 mm thick and have a groove on their upper sides 10, the side walls of which protrude into the cover groove 9 as lip-like webs 12. The cover groove is 9 much wider than the box walls 6, 7 are thick. Approximately in the middle of the floor within the cover groove 9 a bead 13 before which the webs 12 of the box walls 6,7 on the occasion of the assembly of box 1 and Cover 4 spreads apart. Injection openings 15 for the thermoplastic potting compound 8 lead through Bead 13 in the cover 4 into the spray welding channel 11.

Als zusätzliche Fixierung für den Deckel 4 dienen aus der Außenseite der Kastenwand 6 herausragende nasenförmige Anschläge 16.As an additional fixation for the cover 4 are used from the outside of the box wall 6 protruding nose-shaped stops 16.

Die beim Spritzschweißen durch die Einspritzöffnungen 15 hineingepreßte thermoplastische Vergußmasse (z. B. Polystyrol, Polypropylen, Polyäthylen) bildet in dem Kanal 11 eine flüssigkeitsdichte Verbindung. Die lippenartigen Stege 12 der Kastenwände 6, 7 sind dabei an die Innenseiten der vorzugsweise durch Rippen 17 abgestützten Seitenwände 14 der Deckelnuie 9 angedrückt und flüssigkeitsdicht mit ihnen verschweißt.The thermoplastic casting compound pressed in through the injection openings 15 during injection welding (z. B. polystyrene, polypropylene, polyethylene) forms a liquid-tight connection in the channel 11. the lip-like webs 12 of the box walls 6, 7 are included on the inner sides of the side walls 14 of the cover tube 9, which are preferably supported by ribs 17 pressed on and welded to them in a liquid-tight manner.

Die erfindungsgemäße Verbindung von Kasten und Deckel aus thermoplastischem Material kann sowohl bei mehrzelligen als auch bei einzelligen Akkumulatoren Anwendung finden.The inventive connection of box and lid made of thermoplastic material can both find use in multi-cell as well as single-cell accumulators.
