Abstract
Rohranschluß für einen Wärmeübertrager eines Kraftfahrzeuges, insbesondere für einen Kühlmittelkühler (12), mit einem in einen Anschlußstutzen (14) des Wärmeübertragers einsteckbaren Rohr (18), das im Rohrendbereich einen Ringwulst (20) aufweist, mit dem es in Rohreinsteckrichtung (22) an einem Radialflansch (24) des Anschlußstutzens (14) abstützbar ist, sowie mit einer etwa C-förmigen und in radialer Richtung aufsteckbaren Halteklammer (26), deren erste Klammerzungen (32, 34, 36, 38, 40) sich an dem Ringwulst (20) und deren zweite Klammerzungen (42, 44, 46) sich an dem Radialflansch (24) zur Stecksicherung des Rohres (18) in dem Anschlußstutzen (14) abstützen, dadurch gekennzeichnet, daß Enden (48, 50) der Halteklammer-Schenkel (30) jeweils nach außen abgewinkelt sind und in Aufsteckrichtung (23) verlaufende Einführschlitze (52, 54) aufweisen, die mit dem Radialflansch (24) formschlüssig in Eingriff stehen.Pipe connection for a heat exchanger of a motor vehicle, in particular for a coolant radiator (12), with a pipe (18) which can be inserted into a connecting piece (14) of the heat exchanger and has an annular bead (20) in the pipe end region, with which it is inserted into the pipe insertion direction (22) a radial flange (24) of the connection piece (14) can be supported, and with an approximately C-shaped and attachable in the radial direction retaining clip (26), the first clip tongues (32, 34, 36, 38, 40) at the annular bead (20 ) and the second clip tongues (42, 44, 46) are supported on the radial flange (24) for plug-in protection of the tube (18) in the connecting piece (14), characterized in that ends (48, 50) of the retaining clip legs (30 ) are each angled outwards and in Aufsteckrichtung (23) extending insertion slots (52, 54) which are in positive engagement with the radial flange (24).
Description
Die Erfindung betrifft einen Rohranschluß für einen Wärmeübertrager eines Kraftfahrzeuges nach dem Oberbegriff des Anspruchs 1.The The invention relates to a pipe connection for a heat exchanger of a motor vehicle according to the preamble of claim 1.
Ein
solcher Rohranschluß ist
aus der Druckschrift
Nachteilig an einem solchen bekannten Rohranschluß ist, daß die Halteklammer während der Montage an dem Rohrwulst beziehungsweise dem Radialflansch in der Phase, in der sie mit dem Ringwulst beziehungsweise dem Radialflansch erstmalig in Berührung kommt, nicht selbständig in eine eindeutige Aufsteckposition gelangt, sondern zunächst manuell in eine ex akte Aufsteckposition gebracht werden muß und auch noch eine gewisse Strecke manuell exakt geradlinig weitergeführt werden muß, um ein Verkanten während des Aufsteckvorgangs zu vermeiden.adversely at such a known pipe connection is that the retaining clip during the Mounting on the tube bead or the radial flange in the Phase in which they with the annular bead or the radial flange first in touch comes, not independently gets into a unique plug-on position, but first manually must be placed in a ex-act plug-on position and also still a certain distance manually be continued exactly rectilinear must, um a tilting while to avoid the insertion process.
Der Erfindung liegt die Aufgabe zugrunde, einen Rohranschluß der eingangs genannten Art derart weiterzubilden, daß dieser selbständig in eine eindeutige Aufsteckposition gebracht wird, sobald er erstmalig in Berührung mit dem Ringwulst beziehungsweise dem Radialflansch kommt, so daß eine manuelle geradlinige Weiterführung zu Vermeidung des Verkantens während des Aufsteckvorgangs unnötig ist.Of the Invention is based on the object, a pipe connection of the above so-called type such that this independently in a unique slip-on position is brought as soon as he first in touch comes with the annular bead or the radial flange, so that a manual straight forward continuation to avoid tilting during the Aufsteckvorgangs unnecessary is.
Diese Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst.These The object is achieved with the features of claim 1.
Erfindungsgemäß ist vorgesehen, daß Enden der Halteklammer-Schenkel jeweils nach außen abgewinkelt sind und jeweils in Aufsteckrichtung verlaufende Einführschlitze aufweisen, die mit dem Radialflansch formschlüssig in Eingriff stehen. Damit erfüllt der Einfuhrschlitz zwei Funktionen. Einmal ist er gegen den Radialflansch gestützt zur und sorgt dabei parallel zu den zweiten Klammerzungen für eine Stecksicherung des Rohres in dem Anschlußstutzen. Zweitens dient der Einfuhrschlitz als Führungshilfe, um während der Phase, in der die Halteklammer mit dem Ringwulst beziehungsweise dem Radialflansch erstmalig in Berührung kommt, eine eigenständige geradlinige Führung der Halteklammer zu gewährleisten. Im montierten Zustand umschließen die Einführschlitze den Radialflansch formschlüssig etwa tangential und tragen so zu einer Lagestabilisierung der Halteklammer gegenüber dem Anschlußstutzen bei. Die nach außen abgewinkelten Halteklammer-Schenkel erleichtern dabei nach Art einer Einführschräge das Aufschieben der Halteklammer auf den Radialflansch beziehungsweise den Ringwulst. Zusätzlich dazu kann der Einfuhrschlitz an seiner den Halteklammer-Schenkel-Enden zugewandten Seite breiter ausgeführt sein und endet etwa in dem Bereich, in dem die ersten Klammerzungen angeordnet sind.According to the invention, it is provided the sending the retaining clip legs are each angled outwards and respectively have in the direction of insertion insertion slots, with the radial flange form-fitting engage. That fulfilled the entry slot has two functions. Once he is against the radial flange supported and ensures parallel to the second clamp tongues for a plug fuse of the pipe in the connecting piece. Secondly The import slot serves as a guide to while the phase in which the retaining clip with the annular bead or the radial flange comes into contact for the first time, an independent rectilinear guide to ensure the retaining clip. Enclose in assembled state the insertion slots the radial flange form-fitting approximately tangential and thus contribute to a position stabilization of the retaining clip across from the connection piece at. The outward Angled retaining clip leg facilitate the insertion of the retaining clip in the manner of an insertion bevel on the radial flange or the annular bead. Additionally For example, the insertion slot may face at its retaining clip leg ends Page wider be and ends approximately in the area where the first staple tongues are arranged.
In weiterer Ausgestaltung der Erfindung gemäß Anspruch 2 liegt die Innenfläche der Halteklammer an wenigstens drei etwa äquidistant entlang der Winkelerstreckung angeordneten Bereichen am Radialflansch und/oder am Ringwulst flächig an, so daß die verbleibenden Bereiche einen Freiraum bilden. Vor dem Hintergrund, daß die Halteklammer gemäß Anspruch 3 aus Federstahl hergestellt ist und das Rohr beziehungsweise der Anschlußstutzen aus einem Aluminiumwerkstoff besteht, muß die Halteklammer entsprechend oberflächenbehandelt und -beschichtet sein, um eine mögliche Kontaktkorrosion zu vermeiden.In Another embodiment of the invention according to claim 2, the inner surface of the Retaining clip at least three approximately equidistant along the angular extent arranged areas on the radial flange and / or on the annular bead surface, So that the remaining areas form a free space. Against the background, that the Retaining clip according to claim 3 is made of spring steel and the pipe or the connecting branch consists of an aluminum material, the retaining clip must accordingly surface treated and -coated to be a possible Avoid contact corrosion.
Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird im folgenden näher beschrieben.One embodiment The invention is illustrated in the drawings and will be described in more detail below.
