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.
