Such a device is known from US-A-5 759 064 for a lamp socket. In the local device, the seal between a lamp socket and a housing half-shell The device comprises in a plane substantially perpendicular to Biasing direction acting stop surfaces for the seal, which at least partially to the Clamping means are formed. The lamp socket is parallel to an edge of the housing half-shell held at which a provided with an opening for a lamp socket head wall to a perpendicular to this extending side wall abuts.

Femer ist ein weiterhin bekannter Kupplungssteller zum Ein- und Ausrücken einer Fahrzeugkupplung gemäß der DE 197 01 739 Al in einem zweischaligen Gehäuse integriert, das aus zwei Gehäuse-Halbschalen besteht, welche um eine Schwenkachse gegeneinander schwenkbar sind, so daß zwei an jeder Gehäuse-Halbschale angeformte Flansche unter Zwischenlage einer Dichtung aufeinanderliegen. In einer der Gehäuse-Halbschalen ist ein Elektromotor zum Antrieb eines Stößels aufgenommen, der mit einem Kolben eines hydraulischen Geberzylinders verbunden ist. Zur externen Stromversorgung des Elektromotors sind elektrische Steckverbindungen notwendig, welche beispielsweise durch eine Steckerleiste realisiert sind, deren Kopf aus einer Öffnung in einer Wandung einer Gehäuse-Halbschale ragt. Dann muß zur staub- und feuchtigkeitsdichten Abschirmung des Innenraums des Gehäuses gegenüber der Umgebung zwischen dem Steckerleistenkopf und der Gehäusewandung eine unter Vorspannung stehende Dichtung vorgesehen werden.Femer is a further known clutch actuator for engaging and disengaging a vehicle clutch according to DE 197 01 739 Al integrated in a two-shell housing, consisting of two housing half-shells exists, which pivot about a pivot axis against each other are so that two integrally formed on each housing half-shell flanges with the interposition of a seal on each other. In one of the housing half shells is an electric motor for driving a plunger taken with a piston of a hydraulic master cylinder connected is. For external power supply of the electric motor are electrical connectors necessary, which, for example are realized by a connector strip, the head of an opening protrudes in a wall of a housing half-shell. Then must to Dust-proof and moisture-proof shielding of the interior of the housing towards the environment between the power strip header and the housing wall is a prestressed seal be provided.
Solche Kupplungssteller sind zum Teil erheblichen Fahrzeugschwingungen ausgesetzt, weswegen trotz der Vorspannung die Gefahr besteht, daß die Dichtung aufgrund der Schwingbelastung mit der Zeit in einer Ebene senkrecht zur Vorspannrichtung auswandert. Weil dann nicht mehr gewährleistet werden kann, daß die Dichtung an den ihr zugeordneten Dichtflächen der angrenzenden Bauteile anliegt, kann es in einem solchen Fall zu Beeinträchtigungen der Dichtwirkung kommen.Such clutch plates are sometimes considerable vehicle vibrations exposed, so despite the bias the danger exists that the seal due to the vibration load with the Time in a plane perpendicular to the biasing direction emigrated. Because then it can no longer be guaranteed that the seal to the their associated sealing surfaces of the adjacent components is applied, In such a case, it may affect the sealing effect come.
Die Anschlagflächen bilden eine Barriere, die ein Auswandern der Dichtung zuverlässig verhindert. Weil sie teilweise an den ohnehin vorhandenen Spannmitteln ausgebildet sind, sind keine zusätzlichen Teile notwendig, so daß die Fertigungskosten entsprechend niedrig sind. The stop surfaces form a barrier that emigrates reliably prevents the seal. Because they partly to the anyway existing clamping means are formed, are no additional Parts necessary, so that the production costs are correspondingly low are.
Es handelt sich bei dem einen Bauteil um eine Steckerleiste und bei dem anderen Bauteil um eine Gehäuse-Halbschale eines Kraftfahrzeug-Kupplungsstellers, wobei die Steckerleiste parallel zu einer Kante der Gehäuse-Halbschale gehalten ist, an welcher eine mit einer Öffnung für den Steckerleistenkopf versehene Dachwand an eine senkrecht zu dieser verlaufende Seitenwand stößt. Bei der Dichtung handelt es sich um eine den Steckerleistenkopf umschließende Ringdichtung, welche zwischen einem Absatz der Steckerleiste und einem inneren Umfangsrand der Öffnung der Dachwand der Gehäuse-Halbschale eingespannt ist. Die Spannmittel umfassen wenigstens einen sich an der Gehäuse-Halbschale abstützenden Steckkeil, welcher sich zu seinem freien Ende hin keilförmig verjüngt und in eine sich quer zur Vorspannrichtung erstreckende Öffnung der Steckerleiste derart einsteckbar ist, daß eine umso größere Vorspannkraft auf die Steckerleiste und die Ringdichtung ausübbar ist, desto größer die Einstecktiefe ist.It deals in the one component to a power strip and the other Component around a housing half shell of a motor vehicle clutch actuator, with the power strip parallel to one Edge of the housing half-shell is held, on which a with an opening for the power strip head provided roof wall to a perpendicular to this extending side wall abuts. At the seal it is a ring seal enclosing the male connector head, which between a paragraph of the connector strip and a inner peripheral edge of the opening of the roof wall of the housing half-shell is clamped. The tensioning means comprise at least one on the housing half-shell supporting Steckkeil, which tapering towards its free end, wedge-shaped and transversely to the biasing direction extending opening of the connector strip such can be inserted, that a larger biasing force on the connector strip and the ring seal is exercisable, the greater the insertion depth is.
Vorzugsweise ragt der Steckkeil von einer zur Steckerleiste weisenden Seitenfläche eines Klemmbügels weg, der sich gegen die Wirkung der Vorspannkraft am Gehäuse dadurch abstützt, daß an seinen beiden Enden je ein Haltezapfen vorgesehen ist, der einerseits in einer in der Stekkerleiste ausgebildeten Nut geführt und andererseits durch je einen von der Dachwand der Gehäuse-Halbschale nach unten ragenden Haken gekontert ist.Preferably, the plug-in wedge protrudes from a lateral surface facing the connector strip a clamp away, which is against the action of the biasing force supported by the housing that at its two ends depending on a retaining pin is provided, on the one hand in one in the Stekkerleiste trained groove and on the other hand by one each of the roof wall of the housing half-shell downwardly projecting hooks is countered.
In bevorzugter Ausführungsform beinhalten dann die Anschlagflächen einerseits am Klemmbügel angeformte Anschlagleisten, welche entlang seiner Längserstreckung mit Abstand hintereinander angeordnet sind und eine äußere Umfangsfläche der Ringdichtung kontaktieren oder dieser mit geringem Abstand gegenüberliegen. Andererseits sind an der Seitenwand der Gehäuse-Halbschale ausgebildete Stützrippen vorgesehen, die parallel zur Steckerleiste mit Abstand und in Flucht hintereinander angeordnet sind.In a preferred embodiment, then include the stop surfaces on the one hand on the clamping bracket molded stop strips, which arranged along its longitudinal extent at a distance one behind the other are and contact an outer peripheral surface of the ring seal or this with a small distance opposite. On the other hand are formed on the side wall of the housing half-shell supporting ribs provided, which are parallel to the connector strip at a distance and in flight arranged one behind the other.
Durch die weiteren in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Patentanspruch 1 angegebenen Erfindung möglich.By the further measures listed in the dependent claims are advantageous developments and improvements in the Claim 1 indicated invention possible.

Von einem Kupplungssteller zum Ein- und Ausrücken einer Fahrzeugkupplung sind in Fig.1 aus Maßstabsgründen nur eine Halbschale 1 eines aus zwei Gehäuse-Halbschalen bestehenden Gehäuses gezeigt, in welcher ein Ausführungsbeispiel einer Vorrichtung 2 zur Verhinderung des Auswanderns einer schwingungsbelasteten Dichtung integriert ist. Die Funktion eines solchen Kupplungsstellers ist z.B. aus der DE 197 01 739 A1 hinlänglich bekannt, deshalb sollen hierzu keine weiteren Erläuterungen erfolgen.From a clutch plate for engaging and disengaging a Vehicle coupling are in Fig.1 for reasons of scale only a half-shell 1 of a housing consisting of two half-shells housing shown in which an embodiment of a device 2 for Preventing the emigration of a vibration loaded seal is integrated. The function of such a clutch actuator is e.g. out DE 197 01 739 A1 well known, therefore, this should not further explanations.
Wie am besten anhand von Fig.3 zu sehen ist, handelt es sich
bei der Dichtung um eine Ringdichtung 4, die einen aus einer Öffnung 6
in einer Dachwand 8 der Gehäuse-Halbschale 1 ragenden, sich zur
Öffnung 6 hin durch einen Absatz 10 verjüngenden Steckerleistenkopf
12 einer Steckerleiste 14 umschließt. Die Ringdichtung 4 ist zwischen
dem Absatz 10 der Steckerleiste 14 und einem inneren Umfangsrand
der Öffnung 6 der Gehäuse-Halbschale 1 eingespannt und sorgt somit
für eine Abdichtung eines Innenraums des Gehäuses gegenüber der
Umgebung. Die Steckerleiste 14 ist vorzugsweise an einer Kante der
Gehäuse-Halbschale 1 gehalten, an welcher die mit der Öffnung 6 für
den Steckerleistenkopf 12 versehene Dachwand 8 an eine senkrecht
zu dieser verlaufende Seitenwand 16 stößt.As best seen with reference to Figure 3, it is
in the seal around a
Die Halte- bzw. Vorspannkraft, die die Steckerleiste 14 von innen
am inneren Umfangrand der Öffnung 6 der Gehäuse-Halbschale 1 hält
und dadurch auch die Ringdichtung 4 vorspannt, wird durch Spannmittel
erzeugt, weiche gemäß der bevorzugten Ausführungsform einen
sich parallel zur Längsrichtung der Steckerleiste 14 erstreckenden
Klemmbügel 18 beinhalten, dessen als rechtwinklig gebogene Haltezapfen
20 ausgebildete Enden die beiden Stirnflächen der Steckerleiste
14 teilweise umgreifen (Fig.1). The holding or biasing force, the
Wie die Querschnittsdarstellung gemäß der vergrößerten Einzelheit
X von Fig.2 zeigt, stützen sich die Haltezapfen 20 des Klemmbügels
18 mit einem Teil ihrer Bodenfläche an zwei von der Dachwand 8
der Gehäuse-Halbschale 1 parallel nach unten ragenden Haken 22 ab,
welche symmetrisch zueinander angeordnet sind. Andererseits sind die
Haltezapfen 20 auch in zu den Haken 22 hin offenen, an den Stirnflächen
der Steckerleiste 14 angeordneten Nuten 24 bündig geführt, so
daß senkrecht zur Längserstreckung der Nuten 24 und entgegen der in
Fig.3 durch einen gestrichelt gezeichneten Pfeil angedeutete Vorspannrichtung
der Ringdichtung 4 wirkende Kräfte von den Haken 22 der Gehäuse-Halbschale
1 aufgenommen werden können.As the cross-sectional view according to the enlarged detail
X of Fig.2 shows, support the retaining
Wie in Fig.3 gezeigt ist, weist der Klemmbügel 18 einen von seiner
zur Steckerleiste 14 weisenden Seitenfläche wegragenden, vorzugsweise
koplanar zu seiner Mittelebene verlaufenden Steckkeil 26
auf, welcher sich zu seinem Ende hin keilförmig verjüngt. Der Steckkeil
26 ist in eine sich vorzugsweise quer zur Vorspannrichtung der Ringdichtung
4 erstreckende Queröffnung 28 der Steckerleiste 14 einsteckbar,
wobei die Einsteckrichtung in Fig.3 durch einen horizontalen Pfeil
verdeutlicht ist. Die Queröffnung 28 der Steckerleiste 14 ist beispielsweise
durchgehend ausgebildet.As shown in Fig. 3, the
Da sich der Klemmbügel 18 über seine beiden endseitigen Haltezapfen
20 an den Haken 22 der Gehäuse-Halbschale 1 abstützen
kann, wird auf die Steckerleiste 14 und damit auch auf die an ihr anliegenden
Ringdichtung 4 eine senkrecht zur Einschubrichtung des
Steckkeils 26 wirkende Vorspannkraft ausgeübt, wenn der Steckkeil 26
in die Queröffnung 28 der Steckerleiste 14 eingeschoben wird. Wegen
dessen keilförmiger Ausbildung nimmt die Vorspannkraft mit größerer
Einschubtiefe zu. Eine Soll-Vorspannkraft ist beispielsweise dann erreicht,
wenn sich der Steckkeil 26 in seiner in Fig.4 gezeigten vollständig
eingesteckten Endposition befindet, in welcher ein Anschlagkragen
30 des Steckkeils 26 am Rand der Queröffnung 28 der Steckerleiste 14
anschlägt.Since the
Aufgrund der durch den Steckkeil 26 erzeugten Vorspannkraft
wirkt auf die Haltezapfen 20 des Klemmbügels 18 eine Reaktionskraft,
die diese gegen die Haken 22 der Gehäuse-Halbschale drängt. Das
Herauswandern des Klemmbügels 18 wird durch die Vorspannkraft und
die Wegbegrenzung der 2. Gehäuseschale verhindert.Due to the biasing force generated by the
Da die Vorspannkraft auch auf die dem Absatz 10 der Steckerleiste
14 und dem Umfangsrand der Öffnung 6 der Gehäuse-Halbschale
1 zwischengeordneten Ringdichtung 4 wirkt und die Ringdichtung
4 beispielsweise aus einem Material besteht, welches sich
aufgrund der Soll-Vorspannkraft elastisch und/oder plastisch verformt,
ist der durch die beiden Gehäuse-Halbschalen umschlossene Innenraum
des Kupplungsstellers gegenüber der Umgebung zuverlässig abgedichtet.Since the biasing force on the
Wie Fig.4 zeigt, ist die vom Klemmbügel 18 weg weisende Seitenfläche
der Steckerleiste 14 an einer Platine 32 befestigt, welche sich
an der Seitenwand 16 der Gehäuse-Halbschale 1 abstützen kann. Somit
ist die Steckerleiste 14 quer zur Vorspannrichtung der Ringdichtung
4 durch den gegen den Haken 22 geklemmten Klemmbügel 18 gegen
die Seitenwand 16 der Gehäuse-Halbschale 1 gedrückt.As Figure 4 shows, the side facing away from the
Um zu verhindern, daß die Ringdichtung 4 unter Schwingbelastung
seitlich auswandert, sind für sie im wesentlichen senkrecht zur
Vorspannrichtung wirkende Anschlagflächen vorgesehen. Gemäß der
bevorzugten Ausführungsform beinhalten die Anschlagflächen zum einen
am Klemmbügel 18 angeformte Anschlagleisten 34, welche entlang
seiner Längserstreckung mit Abstand hintereinander angeordnet
sind und eine äußere Umfangsfläche der Ringdichtung 4 kontaktieren
oder dieser mit geringem Abstand gegenüberliegen. Zum ändern sind
an der Seitenwand 16 der Gehäuse-Halbschale 1 ausgebildete Stützrippen
36 vorgesehen, welche parallel zur Steckerleiste 14 mit Abstand
und in Flucht hintereinander angeordnet sind, wie am besten anhand
von Fig.5 zu sehen ist, in welcher die Gehäuse-Halbschale 1 ohne
Steckerleiste 14 dargestellt ist. Falls nun die Ringdichtung 4 trotz der
auf sie wirkenden Vorspannkraft aufgrund von Schwingungen dazu
tendieren sollte, in einer Ebene senkrecht zur Vorspannrichtung auszuwandern,
so wird sie durch die Anschlagflächen 34, 36 in ihrer Position
gehalten.To prevent the
Anstatt durch nur abschnittsweise entlang des Umfangs der Ringdichtung angeordnete Anschlagflächen 34, 36 könnten diese gemäß einer weiteren Ausführungsform der Erfindung beispielsweise auch als geschlossene Flächen ausgeführt sein.Instead of only partially along the circumference of Ring seal arranged stop surfaces 34, 36 could this according to another embodiment of the invention, for example also be designed as closed surfaces.
