Description

Leicht lösbare Steckverbindung für Rohrleitungen od. dgl. in Fahrzeugen, insbesondere in Kraftfahrzeugen Die Erfindung bezieht sich auf eine leicht lösbare Steckverbindung für Rohrleitungen od. dgl. in Fahrzeugen, insbesondere in Kraftfahrzeugen, bei welcher das in die Anschlußöffnung einer Rohrleitung oder eines Anschlußkörpers einsteckbare Ende einer zweiten Rohrleitung od. dgl. einen zwischen einem entfernbaren Halteteil und einem Dichtmittel liegenden Wulst aufweist, wobei der Halteteil als C- oder U-förmiger Bügel mit Kreisquerschnitt ausgebildet ist, dessen beide Schenkel in zusammengebautem Zustand in zwei parallele Bohrungen des Anschlußstückes greifen, ohne daß die Enden aus dem Anschlußstück herausragen.Easily detachable plug connection for pipes or the like in vehicles, in particular in motor vehicles The invention relates to an easily detachable Plug connection for pipes or the like in vehicles, especially in motor vehicles, in which that in the connection opening of a pipeline or a connection body insertable end of a second pipe od. Like. One between a removable Has holding part and a sealant lying bead, wherein the holding part as C- or U-shaped bracket is formed with a circular cross-section, the two legs of which in the assembled state reach into two parallel holes in the connection piece, without the ends protruding from the connector.

Bei einer bekannten derartigen Steckverbindung für Rohrleitungen in Kraftfahrzeugen ist ein U-förmiger Haltebügel in den Anschlußkörper gesteckt und wird dort durch Reibschluß gehalten. Es hat sich gezeigt, daß die im Fahrzeug auftretenden Schwingungen und Stöße ein Lösen des Bügels und damit der Steckverbindung bewirken können.In a known such plug connection for pipelines in Motor vehicles, a U-shaped bracket is inserted into the connector body and is held there by frictional engagement. It has been shown that those occurring in the vehicle Vibrations and shocks cause the bracket and thus the connector to loosen can.

Die Erfindung behebt diesen Mangel dadurch, daß der Bügel in an sich bekannter Weise federnd ausgebildet und an seinen beiden Schenkeln mit nach innen gerichteten Nasen versehen ist, die das Rohrende klammerartig und selbstsperrend umfassen.The invention overcomes this deficiency in that the bracket in itself known way resilient and on its two legs with inward directed lugs is provided, which clamp-like and self-locking the pipe end include.

Dadurch ist es gelungen mit einfachen Mitteln eine Steckverbindung zu schaffen, die trotz ihrer verhältnismäßig leichten Lösbarkeit auch unter schweren Betriebsbedingungen, wie sie z. B. durch ständige Erschütterungen in Kraftfahrzeugen hervorgerufen werden, sicher gegen unbeabsichtigtes Lösen ist.This made it possible to create a plug-in connection with simple means to create, despite their relatively easy solvability, even under difficult conditions Operating conditions, such as those z. B. by constant vibrations in motor vehicles is safe against unintentional loosening.

Es sind zwar schon Steckverbindungen mit federnden Haltebügeln bekannt geworden, deren Schenkel jedoch aus dem Anschlußstück herausragen und damit nicht völlig sicher gegen unbeabsichtigtes Lösen, z. B. bei Montagearbeiten, sind.Plug connections with resilient retaining brackets are already known become, but whose legs protrude from the connector and thus not completely safe against unintentional loosening, e.g. B. during assembly work are.

Bei einer solchen Ausführung berührt der Bügel an der engsten Stelle seiner beiden einwärts gebogenen Schenkel das Rohr lediglich punktförmig. Dadurch kann sich der Bügel sehr leicht lösen, zumal er nur durch die schwache Biegung der überstehenden Enden gehalten wird.In such a design, the bracket touches the narrowest point its two inwardly bent legs the tube only punctiform. Through this the bracket can loosen very easily, especially since it is only due to the slight bending of the protruding ends is held.

Bei einer anderen Ausführung eines federnden Bügels weist dieser an der Außenseite eines Schenkelendes eine besondere Haltenase auf. Dies hat den Nachteil, daß zum Lösen des Bügels die Rückseite des Anschlußstückes zugänglich sein muß. Bei Anordnungen im Fahrzeugbau ist dies nicht immer möglich, da das Anschlußstück oft Bestandteil von Mehrfachsteckverbindungen oder von hydraulischen Geräten ist. Die Erfindung wird an Hand eines in der Zeichnung dargestellten Ausführungsbeispieles erläutert. Es zeigt F i g. 1 einen Längsschnitt durch eine Steckverbindung, F i g. 2 eine perspektivische Ansicht der Steckverbindung, wobei die einzelnen Teile auseinandergezogen dargestellt sind und F i g. 3 eine Schnittansicht nach der Linie 111-III in F i g. 1.In another embodiment of a resilient bracket, the latter instructs the outside of one leg end has a special retaining lug. This has the disadvantage that the back of the connector must be accessible to loosen the bracket. In the case of arrangements in vehicle construction, this is not always possible because the connector is often part of multiple plug connections or hydraulic devices. The invention is based on an embodiment shown in the drawing explained. It shows F i g. 1 shows a longitudinal section through a plug connection, F i G. 2 is a perspective view of the connector, with the individual parts are shown exploded and FIG. 3 is a sectional view along the line 111-III in Fig. 1.

In den F i g. 1 bis 3 ist mit 10 ein Verbindungsstück für eine in einem Kraftfahrzeug zu verlegende Rohrleitung 11 und sind mit 12 als U-förmige Sicherungsbügel ausgebildete Halteteile bezeichnet, deren Schenkel 13 und 14 in die Bohrungen 15 bzw. 16 des Verbindungsstückes 10 hineinsteckbar sind.In the F i g. 1 to 3, 10 is a connector for a pipeline 11 to be laid in a motor vehicle and 12 is designated as a U-shaped retaining bracket, the legs 13 and 14 of which can be inserted into the bores 15 and 16 of the connector 10, respectively.

Das Verbindungsstück 10 weist eine Anschlußbohrung 17 und eine an diese sich anschließende Verbindungsbohrung 18 auf. Die Anschlußbohrung 17, deren Durchmesser größer ist als der Durchmesser der Verbindungsbohrung 18, dient der Aufnahme des mit einem Wulst 19 versehenen Endes 11' der Rohrleitung 11 und eines z. B. aus einem Acrylnitril-Kautschuk bestehenden, im Querschnitt viereckigen Dichtringes 20 sowie eines ungeteilten Stützringes 21, z. B. aus Messing.The connecting piece 10 has a connection bore 17 and one this adjoining connecting bore 18 on. The connection hole 17, whose The diameter is greater than the diameter of the connecting bore 18, which serves Receiving the provided with a bead 19 end 11 'of the pipeline 11 and one z. B. consisting of an acrylonitrile rubber, in cross section square sealing ring 20 and an undivided support ring 21, for. B. made of brass.

Der selbstsperrende Sicherungsbügel 12 weist an den Enden der Schenkel 13 und 14 nach innen gerichtete Nasen 13' bzw. 14' auf, die durch Eindrücken bei 13" bzw. 14" erzeugt worden sind.The self-locking safety bracket 12 has at the ends of the legs 13 and 14 inwardly directed lugs 13 'and 14', which have been produced by pressing in at 13 "and 14".

Um die Steckverbindung zwischen der Rohrleitung 11 und dem Verbindungsstück 10 herzustellen, wird zunächst der Dichtring 20 zusammen mit dem Stützring 21 in die Anschlußbohrung 17 hineingepreßt. Dabei kommt die Fläche 20' des Dichtringes 20 gewöhnlich zur Anlage an die Fläche 18' des durch die Anschlußbohrung 17 und die Verbindungsbohrung 18 gebildeten Absatzes. Dann wird das Ende 11' der Rohrleitung 11 in die Öffnungen 21" und 20" des gegenüber der Rohrleitung ein Spiel aufweisenden Stützringes 21 und des Dichtringes 20 eingeführt, wobei die Kante 21' des Stützringes 21 am Wulst 19 abdichtend anliegt. Danach werden die Schenkel 13 und 14 des Sicherungsbügels 12 in die Bohrungen 15 und 16 eingeführt. Der Sicherungsbügel 12 wird bis zum Steg 12' desselben hineingedrückt. Dabei muß ein zwischen den Nasen 13' und 14' und der Oberfläche der Rohrleitung 11 entstehender Reibungswiderstand überwunden werden. Die Nasen 13' und 14' umfassen die eingesteckte Rohrleitung 11 klammerartig. Ein selbständiges Lösen des Sicherungsbügels 12 wird damit verhindert. Nach dem Herstellen der Steckverbindung wird nun Druck auf die Rohrleitung gegeben, wobei sich der Druck des Druckmittels auch auf die Fläche 20' des Dichtringes 20 auswirkt. Dadurch wird der Dichtring 20, der Stützring 21 und die Rohrleitung 4 über den Wulst 19 in axialer Richtung an den Sicherungsbügel 12 geschoben.In order to establish the plug connection between the pipeline 11 and the connecting piece 10, the sealing ring 20 together with the support ring 21 is first pressed into the connection bore 17. The surface 20 'of the sealing ring 20 usually comes to rest against the surface 18' of the shoulder formed by the connecting bore 17 and the connecting bore 18. Then the end 11 'of the pipeline 11 is inserted into the openings 21 "and 20" of the support ring 21, which has clearance with respect to the pipeline, and of the sealing ring 20, the edge 21' of the support ring 21 sealingly against the bead 19. Thereafter, the legs 13 and 14 of the securing bracket 12 are inserted into the bores 15 and 16. The securing bracket 12 is pressed in as far as the web 12 'of the same. A frictional resistance that arises between the noses 13 'and 14' and the surface of the pipeline 11 must be overcome. The lugs 13 'and 14' encompass the inserted pipeline 11 in the manner of a clamp. Independent loosening of the securing bracket 12 is thus prevented. After the plug connection has been established, pressure is now applied to the pipeline, the pressure of the pressure medium also having an effect on the surface 20 ′ of the sealing ring 20. As a result, the sealing ring 20, the support ring 21 and the pipeline 4 are pushed over the bead 19 in the axial direction onto the securing bracket 12.
