Description

Die Erfindung betrifft ein Gehäuse, insbesondere einen Heiz- bzw. Klimakasten einer Heizung bzw. Klimaanlage eines Kraftfahrzeuges mit einem radial abragenden Stutzen und einer sich im Öffnungsbereich des Stutzens innerhalb des Gehäuses vorgesehenen Strömungsleitwand.The invention relates to a housing, in particular a heating or air conditioning box of a heater or air conditioning system of a motor vehicle with a radially protruding nozzle and one flow guide wall provided in the opening area of the nozzle within the housing.

Bei Gehäusen mit einer derartigen Strömungsleitwand war die Leitwand bisher einstückig mit dem Gehäuse ausgebildet. Auf den außen abragenden Stutzen konnte bei einem derartigen Gehäuse ein Rohrkanal aufgeschoben und mit dem Stutzen über Federmittel verrastet sein.In the case of housings with such a flow guide wall, the guide wall was previously integral with trained the housing. With such a Housing be pushed onto a pipe duct and locked with the socket via spring means.

Eine über eine eingelegte Bügelfeder verrastete Rohrverbindung ist aus US 2,546,387 be­ kannt. Die dort eingelegte Feder dient ausschließlich zur Erzeugung des Rastverschlusses und erfüllt darüber hinaus keine weitere Funktion. Sie kann insbesondere bei einem Lösen der Rohrverbindung verloren gehen.A pipe connection locked via an inserted bow spring is from US 2,546,387 knows. The spring inserted there is used only to generate the snap lock and has no other function. You can especially when loosening the Pipe connection is lost.

Die Erfindung beschäftigt sich mit dem Problem, ein solches Gehäuse mit Bezug auf die an diesem vorzusehende Leitwand rationeller als bisher herstellen zu können. Gelöst wird dieses Problem durch ein Gehäuse mit sämtlichen Merkmalen des Patentanspruchs 1.The invention is concerned with the problem of such a housing with respect to the to be able to produce this guide wall more efficiently than before. This is solved Problem by a housing with all the features of claim 1.

Eine zweckmäßige Ausgestaltung ist Gegenstand des Anspruchs 2.A practical embodiment is the subject of claim 2.

Besonders vorteilhaft läßt sich die Erfindung realisieren bei einem Gehäuse mit einem abra­ genden Stutzen aus Kunststoff, bei dem bei der Herstellung des Gehäuses das Herstellungs­ werkzeug in Richtung der Stutzenachse entformt werden soll. In diesem Fall dürfen am Um­ fang des Stutzens keine nach radial außen abstehenden Vorsprünge vorhanden sein. Bei der erfindungsgemäßen Lösung müssen in dem Stutzen lediglich fensterartige Öffnungen für das Einführen vorgespannter Rastnasen vorgesehen werden, was fertigungsmäßig rationell mög­ lich ist.The invention can be implemented particularly advantageously in a housing with an abra given plastic connector, in which the manufacture of the housing tool in the direction of the nozzle axis. In this case, at Um no protrusions protruding radially outwards are present at the start of the connecting piece. In the Solution according to the invention only have window-like openings for that in the nozzle  Introducing pre-tensioned locking lugs are provided, which is rationally possible in terms of production is.

Bei der erfindungsgemäßen Lösung kann die Leitwand in demjenigen Bereich, in dem sie mit dem Stutzen verrastet wird, als ein die Rastnasen aufweisender Ring oder auch als eine ring­ förmige Spange ausgebildet sein. Die Spange muß dabei lediglich eine solche Umfangslänge besitzen, daß eine axiale Fixierung innerhalb des Gehäusestutzens, in die sie eingeschoben ist, sichergestellt ist.In the solution according to the invention, the guide wall can be in the area in which it is connected the nozzle is locked as a ring having the locking lugs or as a ring be shaped clasp. The clip only has to have such a circumferential length possess that an axial fixation within the housing socket into which they are inserted is ensured.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt.An embodiment is shown in the drawing.

Diese zeigtThis shows

einen Schnitt durch einen Gehäuseausschnitt mit einem nach außen abragenden Stutzen, auf dem ein Rohrkanal abzuggesichert aufgesteckt ist.a section through a housing cutout with a  outwardly protruding nozzle on which a pipe duct is secured against deduction.

In die Gehäusewand 1 eines lediglich bereichsweise dargestellten Gehäuses ist ein nach außen abragender Stutzen 2 eingeformt. Das Gehäuse und der Stutzen 2 sind aus Kunststoff.In the housing wall 1 of a housing shown only in certain areas, an outwardly projecting nozzle 2 is molded. The housing and the nozzle 2 are made of plastic.

Das Gehäuse ist zusammen mit dem Stutzen 2 in einem Werkzeug hergestellt, das in Richtung der Achse des Stutzens 2 entformt wird.The housing is produced together with the connector 2 in a tool that is removed from the mold in direction of the axis of the socket. 2

In den Stutzen 2 ist ein Träger 3 mit einem ringförmi­ gen Bund 4 eingeschoben. Der Ringbund 4 besitzt radial federnd angeformte Zungen 5 mit an den freien Enden radial abstehenden Rastnasen 6. Die Rastnasen 6 durch­ dringen in dem Stutzen 2 vorgesehene Fenster 7, aus denen sie nach außen herausragen.In the nozzle 2 , a carrier 3 is inserted with a ring-shaped collar 4 . The annular collar 4 has radially resiliently shaped tongues 5 with locking lugs 6 projecting radially at the free ends. The locking lugs 6 penetrate through the stub 2 provided windows 7 , from which they protrude outwards.

Auf den Stutzen 2 ist ein Rohrkanal 8 aufgeschoben. Zur Erzielung einer gewünschten Abzugsicherung ist in das aufgeschobene Ende der Wand des Rohrkanales 8 eine umlaufende Rille 9 eingeformt. Mit dieser Rille 9 verrastet der aufgeschobene Rohrkanal 9 an den Rast­ nasen 6. Der über die Umfangsrille 9 axial zum aufge­ schobenen Ende des Rohrkanales 8 hinausragende Ringbereich des Rohrkanales 8 gewährleistet eine si­ chere Umfangsabdichtung gegenüber dem Stutzen 2 des Gehäuses.A pipe duct 8 is pushed onto the connector 2 . To achieve a desired trigger protection, a circumferential groove 9 is formed in the pushed-on end of the wall of the pipe channel 8 . With this groove 9, the pushed-on pipe channel 9 latches on the locking lugs 6 . The over the circumferential groove 9 axially to the pushed up end of the pipe channel 8 projecting annular area of the pipe channel 8 ensures a si chere peripheral seal against the nozzle 2 of the housing.

Als integriertes Teil des Trägers 3 ist an diesen eine Strömungsleitwand 10 angeformt und kann dadurch oh­ ne direkte Anformung an das Gehäuse bzw. die Gehäu­ sewand 1 im Inneren des Gehäuses gehalten werden. Das Gehäuse kann beispielsweise bei einem Kraftfahr­ zeug der Heiz- bzw. Klimakasten einer Heizung bzw. Klimaanlage sein. Die Strömungsleitwand 10 stellt dann ein bei solchen Gehäusen bekanntes Luftleitteil dar.As an integrated part of the carrier 3 , a flow guide wall 10 is integrally formed thereon and can thus be held in the interior of the housing without a direct molding to the housing or the housing wall 1 . The housing can be, for example, in a motor vehicle, the heating or air conditioning box of a heating or air conditioning system. The flow guide wall 10 then represents an air guide part known in such housings.
