Description
Poldurchführung im Zellendeckel eines Akkumulators, insbesondere eines Bleiakkumulators Die Erfindung bezieht sich auf eine Poldurchfüh rung im Zellendeckel eines Akkumulators, insbe sondere eines Bleiakkumulators. Es sind Poldurch führungen bekannt, bei denen in den Deckel bei des sen Herstellung eine Buchse eingepasst wird, deren Aussenflächen mit ringartigen Vertiefungen und Er höhungen versehen sind, um die Berührungsfläche zwischen Buchse und Deckel zu vergrössern.
Es sind auch Durchführungen bekannt, die Buchsen aufwei sen, bei denen der Kriechweg des Elektrolyten auf einer kurzen Strecke nach unten geführt oder die Aussenfläche konisch gestaltet ist.
Demgegenüber ist die Erfindung dadurch ge kennzeichnet, dass die Aussenfläche der Buchse sich nach der Basis hin verbreitert und dass auf der Unterseite eine zu einer axialen Öffnung in der Buchse konzentrisch verlaufende Rille vorgesehen ist. Mit der Verbreiterung nach der Basis wird die zu sätzliche Anordnung dieser Riffen ermöglicht, die von dem Deckelmaterial ausgefüllt werden. Vorzugs weise hat die Rille einen V-förmigen Querschnitt.
Die Aufgabe der Erfindung ist in der Schaffung einer Dichtungsbuchse zu sehen, die bei geringem Materialaufwand einfach herzustellen ist und mit der verhindert wird, dass Elektrolyt über Kriechwege auf den Deckel gelangt. Mit der axialen Öffnung in der Buchse konzentrisch angeordneten Rille auf der Un terseite der nach der Basis hin sich verbreiternden Buchse wird dies in überraschend vollkommener Weise erreicht.
Das ist teilweise auf die vergrösserte, für die Abdichtung in Betracht kommende Fläche zurückzuführen und teilweise damit begründet, dass durch die vorgesehene Vertiefung der Kriechweg der etwa dorthin gelangenden Flüssigkeit nach abwärts gerichtet wird, bevor sie an den äusseren Rand der unten verbreiterten Buchse gelangt. Um die Berührungsfläche zwischen Buchse und Deckel zu vergrössern, kann die Aussenfläche der Buchse stufenförmig ausgebildet sein.
Die Anordnung der konzentrischen Vertiefung in der verbreiterten Basis ergibt eine sehr viel wirk samere Abdichtung, als dies z. B. durch Anordnung von am Umfang vorgesehene Flansche oder derglei chen der Fall ist.
Anhand der Zeichnung wird ein Ausführungs- beispiel. der Erfindung erläutert.
Fig. 1 zeigt eine Poldurchführung im Querschnitt im Deckel eines Akkumulatorgefässes.
Fig.2 zeigt eine Buchse in Seitenansicht.
Auf Fig. 1 bezeichnet 1 einen Teil des Deckels des Akkumulatorgefässes. Durch einen Durchlass im Deckel erstreckt sich der Polkopf 2, der mit Hilfe einer Polbrücke an die Elektrodenplatten 3 ange schlossen ist. Der Polkopf wird auf einem Teil seiner Länge von der Buchse 4 umschlossen, die in den Deckel 1 fest eingegossen ist und mit ihrem oberen Teil über die Oberkante des Deckels hinausragt. Wie aus der Zeichnung ersichtlich, ist die Buchse 4 nach der Basis hin verbreitert.
Die Mantelfläche ist mit stufenförmigen Absätzen versehen, um die Berührungsfläche zwischen Buchse 4 und Deckel 1 zu vergrössern, so dass eine gute Dichtung erreicht wird. In der nach unten verbreiterten Basis der Buchse ist eine zum axialen Durchlass der Buchse konzentrische Rille 5 mit V-förmigem Querschnitt vorgesehen. Durch diese Rille wird die Berührungs fläche von Buchse und Deckel noch weiterhin ver grössert, so dass die Abdichtung zwischen Deckel und Buchse besonders wirksam ist.
Der axiale Durch lass der Buchse hat etwa den gleichen Durchmesser wie der Polkopf, so dass dieser an der zylindrischen Innenwandung der Buchse anliegt, Die Buchse 4 ist aus Metall, z. B. Blei oder einer bleihaltigen Legierung, hergestellt und vor teilhaft in den Deckel 1 bei seiner Herstellung durch Giessen. Pressen oder ähnliches eingepasst. Damit sich die Buchse nach dem Einbau nicht um ihre Längsachse drehen kann, ist sie an der Aussenfläche mit Auskragungen 7a versehen. Zweckmässigerweise wird die Buchse mit mindestens zwei Auskragungen versehen.
Die äusseren Anschlüsse werden an die Pole durch einen Polverbinder 6 angeschlossen, in dessen öff- nung der über den Deckel 1 hinausragende Teil der Buchse 4 hineinragt. Der Polverbinder ist an der Buchse 4 und am Polkopf 2 festgelötet, indem die Öffnung des Polverbinders mit einer Schmelze 7, z. B. Blei, ausgefüllt wird.
Das obere Ende des Pol kopfes 2 soll etwas unterhalb der Oberkante der Buchse abschliessen, wie aus Fig. 1 ersichtlich. Beim Löten wird dadurch der oberste Teil der Buchse vom Lötmetall ganz ausgefüllt und eine gute Ab dichtung zwischen Buchse und Polkopf gewährleistet.
Pole leadthrough in the cell cover of an accumulator, in particular a lead accumulator The invention relates to a pole leadthrough in the cell cover of an accumulator, in particular a lead accumulator. There are Poldurch guides known in which a socket is fitted into the cover in the production of the sen, the outer surfaces of which are provided with ring-like depressions and heightened heights to enlarge the contact area between the socket and cover.
There are also known bushings, the sockets aufwei sen in which the leakage path of the electrolyte is guided down a short distance or the outer surface is conical.
In contrast, the invention is characterized in that the outer surface of the bushing widens towards the base and that on the underside there is a groove running concentrically to an axial opening in the bushing. With the widening after the base, the additional arrangement of these reefs is made possible, which are filled by the cover material. Preferably, the groove has a V-shaped cross section.
The object of the invention is to be seen in the creation of a sealing bushing which is easy to manufacture with little material expenditure and which prevents electrolyte from reaching the cover via creepage paths. With the axial opening in the socket concentrically arranged groove on the underside of the socket widening towards the base, this is achieved in a surprisingly perfect manner.
This is partly due to the enlarged area that can be used for the seal and partly due to the fact that the creepage path of the liquid that may get there is directed downwards through the provided recess, before it reaches the outer edge of the socket widened below. In order to enlarge the contact area between the socket and cover, the outer area of the socket can be designed in a stepped manner.
The arrangement of the concentric recess in the widened base results in a much more effective seal than this, for. B. by the arrangement of flanges provided on the circumference or derglei chen is the case.
An exemplary embodiment is provided on the basis of the drawing. the invention explained.
Fig. 1 shows a pole leadthrough in cross section in the cover of an accumulator vessel.
Fig.2 shows a socket in side view.
In Fig. 1, 1 denotes a part of the lid of the accumulator vessel. The pole head 2, which is connected to the electrode plates 3 with the aid of a pole bridge, extends through a passage in the cover. The pole head is enclosed over part of its length by the socket 4, which is firmly cast in the cover 1 and protrudes with its upper part beyond the upper edge of the cover. As can be seen from the drawing, the socket 4 is widened towards the base.
The jacket surface is provided with stepped shoulders in order to enlarge the contact surface between the socket 4 and cover 1, so that a good seal is achieved. In the downwardly widened base of the bushing, a groove 5 with a V-shaped cross section is provided which is concentric with the axial passage of the bushing. Through this groove, the contact surface of the socket and cover is still enlarged so that the seal between the cover and socket is particularly effective.
The axial passage of the socket has approximately the same diameter as the pole head, so that it rests against the cylindrical inner wall of the socket. The socket 4 is made of metal, e.g. B. lead or a lead-containing alloy, made and in front of geous in the lid 1 during its manufacture by casting. Pressing or the like fitted. So that the bush cannot rotate about its longitudinal axis after installation, it is provided with projections 7a on the outer surface. The socket is expediently provided with at least two projections.
The outer connections are connected to the poles by a pole connector 6, into the opening of which the part of the socket 4 protruding beyond the cover 1 protrudes. The pole connector is soldered to the socket 4 and the pole head 2 by the opening of the pole connector with a melt 7, z. B. lead, is filled.
The upper end of the pole head 2 should terminate somewhat below the upper edge of the socket, as can be seen from FIG. When soldering, the top part of the socket is completely filled by the solder and a good seal between the socket and pole head is guaranteed.
