Abstract
Description
Stand der TechnikState of the art
Die Erfindung geht aus von einer Leitungsanschlussvorrichtung für eine medienführende Leitung nach der Gattung des Patentanspruchs 1 und ferner von einem Stecker umfassend eine derartige Leitungsanschlussvorrichtung.The invention is based on a line connection device for a media-carrying line according to the preamble of patent claim 1 and also on a plug comprising such a line connection device.
Derartige Leitungsanschlussvorrichtungen werden zur Kopplung von medienführenden Leitungen wie z.B. Kraftstoffleitungen eingesetzt. Da die Leitungen häufig als Schlauchleitungen ausgebildet sind, sind die Leitungsanschlussvorrichtungen üblicherweise mit einer Profilierung versehen, die beispielsweise durch Außendurchmesserverdickungen wie Rippen realisierbar ist, um die Leitungen sicher an der zugeordneten Leitungsanschlussvorrichtung zu fixieren. Es besteht dabei jedoch die Gefahr, dass je nach Profilierung schon beim Anbringen einer Leitung an der entsprechenden Leitungsanschlussvorrichtung eine Beschädigung an der Schlauchinnenschicht des auf den Anschlussbereich der Leitungsanschlussvorrichtung aufgezogenen Schlauchabschnitts auftreten kann, die dann beispielsweise zu Undichtigkeiten bzw. Leckagen führen kann.Such conduit connection devices are used for coupling media carrying conduits such as e.g. Fuel lines used. Since the lines are often designed as hose lines, the line connection devices are usually provided with a profiling, which can be realized, for example, by outer diameter thickenings such as ribs in order to securely fix the lines to the associated line connection device. However, there is the risk that, depending on the profiling already when attaching a line to the corresponding line connection device damage to the inner tube layer of the mounted on the connection area of the line connection device hose section can occur, which can then lead to leaks or leaks, for example.
Vorteile der ErfindungAdvantages of the invention
Die Leitungsanschlussvorrichtung mit den kennzeichnenden Merkmalen des Patentanspruchs 1 hat den Vorteil, dass bei einem mit Außenprofilierung versehenen Anschlussstutzen eine elastische Beschichtung als Zwischenschicht bzw. dämpfende Pufferschicht für den darüber angebrachten Schlauchabschnitt wirkt und dadurch verhindert, dass sich die Außenprofilierung des Anschlussstutzens in den Innenbereich des die Leitungsanschlussvorrichtung umschließenden Schlauchabschnitts einprägt, und bei einem ohne eine derartige Außenprofilierung versehenen Anschlussstutzen die Beschichtung aufgrund ihrer Elastizität als Bindeglied zwischen dem starr ausgebildeten Trägermaterial des Anschlussstutzens und einem zur Ankopplung vorgesehenen Schlauchleitungsabschnitt fungiert und dabei sowohl eine Dichtfunktion als auch eine Haltefunktion ausübt. Dadurch wird einer Rissbildung in dem entsprechenden Schlauchabschnitt konstruktiv entgegengewirkt und zusätzliche Haltemittel wie z.B. Schlauchschellen können kostensenkend entfallen.The line connection device with the characterizing features of claim 1 has the advantage that in an externally profiled connecting piece an elastic coating acts as an intermediate layer or damping buffer layer for the hose section mounted above and thereby prevents the outer profile of the connecting piece in the interior of the Due to its elasticity, the coating, due to its elasticity, acts as a link between the rigidly formed carrier material of the connecting piece and a hose line section provided for coupling and thereby exerts both a sealing function and a holding function. As a result, cracking in the corresponding tube section is structurally counteracted and additional holding means such as e.g. Hose clamps can be omitted cost-reducing.
Weitere vorteilhafte Weiterbildungen und Ausgestaltungen der Erfindung ergeben sich durch die in den Unteransprüchen aufgeführten Maßnahmen.Further advantageous developments and refinements of the invention will become apparent from the measures listed in the dependent claims.
Eine zweckmäßige Weiterbildung der Erfindung kann darin bestehen, dass am Außenumfang des Anschlussstutzens wenigstens eine Vertiefung ausgebildet ist, um die Haltekraft der elastisch ausgebildeten Schicht auf dem Anschlussbereich des Anschlussstutzens zu erhöhen. Dabei kann die wenigstens eine Vertiefung zum Erzielen einer in Umfangsrichtung homogenen Haltekraft als umlaufende Ringnut ausgeführt sein.An expedient development of the invention may be that at least one recess is formed on the outer circumference of the connecting piece in order to increase the holding force of the elastically formed layer on the connection region of the connecting piece. In this case, the at least one depression to achieve a homogeneous in the circumferential direction holding force can be designed as a circumferential annular groove.
Eine relativ einfach zu realisierende Ausgestaltung der Erfindung sieht vor, dass die Schicht aus einem Elastomer gebildet ist, um ihre elastische Eigenschaft zu erzielen.A relatively easy to implement embodiment of the invention provides that the layer is formed of an elastomer in order to achieve its elastic property.
Bei einem mit einer Außenprofilierung versehenen Anschlussstutzen ist es vorteilhaft, wenn die Schichtdicke der elastisch ausgebildeten Schicht im Wesentlichen konstant in Axialerstreckung des Anschlussstutzens ausgebildet ist. Dadurch wird die Außenprofilierung des Anschlussstutzens von der darauf dünn aufgebrachten elastischen Schicht nachgebildet.In the case of a connection piece provided with an external profiling, it is advantageous if the layer thickness of the elastically formed layer is formed substantially constant in the axial extension of the connection piece. As a result, the external profiling of the connection piece is simulated by the elastic layer applied thinly thereon.
Eine dazu alternative Ausführungsform der Erfindung kann darin bestehen, dass die Schichtdicke der elastisch ausgebildeten Schicht in Axialerstreckung des Anschlussstutzens veränderlich ist. Dadurch kann die elastisch ausgebildete Schicht ein eigenes Außenprofil aufweisen.An alternative embodiment of the invention may consist in that the layer thickness of the elastically formed layer in the axial extension of the connecting piece is variable. As a result, the elastically formed layer may have its own outer profile.
