Akkumulator mit Kunststoffkasten und -deckelAccumulator with plastic case and cover

!Die Erfindung betrifft einen Akkumulator mit einem Kasten aus thermoplastischem Kunststoff und mit einem die Oberseiten der Außen- und Zwischenwände des Kastens überdeckenden, ebenfalls aus thermoplastischem Kunststoff bestehenden Deckel, die mit offenen, sich zu einem geschlossenen Kanal ergänzenden Nuten zur Aufnahme einer die beiden ,Teile verschweißenden Kunststoff-Spritzmasse versehen sind, die Außen- und etwaige Zwischenwände des Kastens in dünnwandige, die Nuten in den Kastenwänden begrenzende , lippenartige Stege auslaufen, die in die Deckelnuteii hineinragen und durch in die Kanäle eingespritzteThe invention relates to an accumulator with a box from thermoplastic plastic and with one the tops of the Outer and partition walls of the box covering, also made of thermoplastic cover, which with open grooves that complement each other to form a closed channel for receiving a plastic injection molding compound that welds the two parts are provided, the outer and any intermediate walls of the box in thin-walled, the grooves in the box walls delimiting, run out lip-like webs that into the Deckelnuteii protrude and injected into the channels

Dicht- und Schweißmasse an die Innenflanken der Deckelnuten und mit' ihnen verschweißt sind,Sealing and welding compound on the inner flanks of the cover grooves and welded to them,

Bei einer derartigen Verbindung des Deckels mit dem Kasten müssen die Kastenwände verhältnismäßig dick ausgeführt sein, weil die Hüten 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.With such a connection between the lid and the box, the box walls must be made relatively thick, because the hats in the tops of the box walls must not be too tight; if the grooves are too narrow, there is frictional resistance between potting compound and channel wall in so-called spray welding so large that the thermoplastic potting compound the grooves are not filled over their entire length and are squeezed out of the channel if the injection pressure is too high.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, eine Spritzschweißverbindung für Kasten und Deckel aus thermoplastischem Kunststoff zu entwickeln, die aus Materialeinsparung sgründen dünnere Außen- und Zwischenwände zuläßt.In contrast, the invention is based on the object of a spray-welded connection for the box and lid made of thermoplastic To develop plastic that allows thinner outer and partition walls to save material.

Eine^besonders gute Lösung ergibt sich, wenn gemäß der Erfindung die Dicke der Kastenwände wesentlich geringer ist als die Breite der Deckelnuten, aus deren Bodenmitte ein als Keil wirkender Wulst herausragt, der parallel zu den Seitenwänden der Deckelnute verläuft und die lippenartigen Stege der Kastenwand-Oberseiten vor dem Einbringen der Spritzmasse auseinanderspreizt. — — - .. ._A particularly good solution is obtained if according to the invention the thickness of the box walls is much less than the width of the cover grooves, from the bottom center of which is a wedge Acting bead protrudes, which runs parallel to the side walls of the lid groove and the lip-like webs of the box wall tops spreads apart prior to the injection of the injection molding compound. - - - .. ._

Der in Pig. 1 gezeichnete Akkumulator besteht aus einem Blockkasten1 mit den Zellengefäßen 2, in denen sich je ein Plattenblock 3 und Elektrolyt befindet, aus dem Blockdeckel t 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 A^ergußmasse 8 in einen .gemeinsam von Deckelnuten 9 und Kastenwandnuten 10 (Pig. 3) gebildeten, durchgehend verlaufenden, in sich geschlossenen Kanal 11 (Pig. 4) mit Hilfe einer Spritzgießmaschine.The one in Pig. 1 shown accumulator consists of a block box1 with the cell vessels 2, in each of which there is a plate block 3 and electrolyte, from the block cover t with the Sealing plug 5 and the cell connectors, not shown and terminal poles. Box 1 and lid 4 are hereby so-called Spray welding connected to each other; Injection welding is the injection of thermoplastic Plastic as a casting compound 8 in a common of cover grooves 9 and box wall grooves 10 (Pig. 3) formed, continuously running, self-contained channel 11 (Pig. 4) using an injection molding machine.

Die neue Spritzschweißverbihdung 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 Ausführungsb.eispiel sind die Kastenwände 6, 7 1S5 mm dick und haben an ihren Oberseiten' eine Nute 10, deren Seitenwände als. lippenartige. Siege 12 in eine 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 parallel zu den Seitenwänden 14 der Deckelnute 9 verläuft und die Stege .12 der Kastenwände "6, 7 auseinanderspreizt.

In the illustrated embodiment, the box walls 6, 7 1 S are 5 mm thick and have a groove 10 on their upper sides, the side walls of which as. lip-like. Siege 12 protrude into a cover groove 9. The cover groove 9 is much wider than the box walls 6, 7 are thick. A bead 13 protrudes approximately in the center of the bottom inside the cover groove 9, which runs parallel to the side walls 14 of the cover groove 9 and spreads the webs 12 of the box walls 6, 7 apart. Injection openings 15 for the thermoplastic potting compound 8 lead through the bead 13 in the cover 4 into the spray welding channel 11 .. - ■ "" .. -. '■. -.:'■■-''■".' - ■ ■■ · - 4 -

Als zusätzliche Fixierung für den Deckel 4 dienen aus der Kastenaußenwand 6 herausragende Nasen 16 oder nicht darge-" stellte herkömmliche Spritzschweißverbindungen an den Kastenaußenwänden 6, die eng in die Deckelnute hineinpassen.As an additional fixation for the cover 4 are used from the Box outer wall 6 protruding lugs 16 or not shown " provided conventional spray-welded joints on the outer walls of the box 6, which fit tightly into the lid groove.

Die beim Spritzschweißen durch die Einspritzöffnungen 15 hineingepreßte thermoplastische Vergußmasse (z.B. Polystyrol, Polypropylen, Polyäthylen) bildet in dem Kanal 11 eine lückenlose Verbindung. Die lippenartigen Stege 12 der Kastenwände 6, 7 sind dabei an die Innenseiten der vorzugsweise durcn Rippen 17 abgestützten Seitenwände 14 der Deckelnute 9 angedrückt und flüssigkeitsdicht mit ihnen verschweißt.The thermoplastic potting compound (e.g. polystyrene, Polypropylene, polyethylene) forms a seamless connection in the channel 11. The lip-like webs 12 of the box walls 6, 7 are on the inside of the side walls 14 of the cover grooves 9, which are preferably supported by ribs 17 pressed on and welded to them in a liquid-tight manner.
