Abstract
Anschlußpol für einen Akkumulator mit einem Anschlussteil, an welches ein Verbraucher anschließbar ist, und einem Sockelteil, das umlaufende Rillen aufweist, und in ein Gehäuse des Akkumulators einsetzbar ist, wobei die umlaufenden Rillen mit einem die Rillen ausfüllenden Kunststoff eine Labyrinthdichtung bilden und wobei an der Unterseite des Sockelteiles eine ebene Fläche mit einem keilförmig ausgebildeten umlaufenden Kantenbereich, welcher in das umgebende Kunststoffmaterial ragt, vorgesehen ist, dadurch gekennzeichnet, dass der umlaufende keilförmige Kantenbereich (3) als gegenüber der ebenen Fläche (10) nach unten ragender spitzer Vorsprung ausgebildet ist.Connection pole for one Accumulator with a connector to which a consumer connectable is, and a base part which has circumferential grooves, and in a housing of the accumulator can be used, the circumferential grooves with one filling the grooves Plastic form a labyrinth seal and being on the bottom of the base part with a flat surface one wedge-shaped trained peripheral edge area, which in the surrounding Plastic material protrudes, is provided, characterized in that that the circumferential wedge-shaped Edge area (3) than opposite flat surface (10) downward protruding projection is formed.
Description
Die
Erfindung betrifft einen Anschlußpol nach dem Oberbegriff des
Patentanspruches 1, wie aus der
Derartige
Anschlusspole werden, wie auch aus der
Aufgabe der Erfindung ist es, einen Anschlußpol der eingangs genannten Art zu schaffen, der eine verbesserte Labyrinthdichtung aufweist.task the invention is a connection pole of the aforementioned To create type that has an improved labyrinth seal.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruches 1 gelöst.This The object is achieved by the characterizing features of claim 1 solved.
An dem nach unten ragenden keilförmigen Kantenbereich des Sockelteils entsteht beim Schrumpfen des den Sockelteil umgebenden Kunststoffes zwischen Kunststoff und Polhülse eine starke Keilwirkung, die eine zusätzliche Labyrinthdichtungswirkung bringt. Hierbei können in dem sich an dem keilförmig ausgebildeten Kantenbereich anschließenden Mantelbereich des Sockelteils ferner zwei im Querschnitt konisch geformte umlaufende Vorsprünge vorhanden sein, zwischen denen eine etwa im Profil V-förmige Rille gebildet wird. Auch hierdurch wird eine zusätzliche Labyrinthdichtung noch erreicht.On the downward wedge-shaped edge area of the base part arises when the surrounding of the base part shrinks Plastic between plastic and pole sleeve has a strong wedge effect, the one additional Brings labyrinth sealing effect. Here can be formed on the wedge-shaped Subsequent edge area Shell area of the base part also two conical in cross section shaped circumferential projections be present, between which an approximately V-shaped groove is formed. This also adds an additional labyrinth seal reached.
Durch die im Profil konische Form der im unteren Kantenbereich des Sockelteils gewonnenen zusätzlichen Labyrinthringe, an welchen der Kunststoff unbeeinflußt schrumpfen kann, entsteht eine sehr starke Flächenpressung zwischen dem Metall, insbesondere Blei, des Sockelteils und dem Kunststoff. Ferner gewinnt man eine Vergrößerung der Dichtfläche. Die Dichtigkeit der in den Gehäusedeckel des Akkumulators eingesetzten Anschlußpols wird hierdurch verbessert.By the conical shape of the profile in the lower edge area of the base part won additional Labyrinth rings on which the plastic shrink unaffected can, there is a very strong surface pressure between the metal, in particular Lead, the base part and the plastic. You also win one Enlargement of the sealing surface. The Tightness of the in the housing cover the connecting pole used in the accumulator is thereby improved.
Anhand der Figuren wird an einem Ausführungsbeispiel die Erfindung noch näher erläutert. Es zeigt:Based of the figures is based on an embodiment the invention even closer explained. It shows:
