Abstract
Description
Die Erfindung betrifft eine Abzugsicherung für einen auf ei nen von einem, insbesondere aus Kunststoff gefertigten, Ge häuse nach außen abragenden Stutzen aufschiebbaren Rohrkanal.The invention relates to a trigger protection for an egg NEN from a, especially made of plastic, Ge Pipe can be slid out of the housing and protrudes outwards.
Die Erfindung beschäftigt sich mit dem Problem, durch eine solche Abzugsicherung die Herstellung eines Gehäuses mit ei nem nach außen abragenden Stutzen nicht negativ zu beeinflus sen. Dies gilt insbesondere für ein Gehäuse mit abragendem Stutzen aus Kunststoff, bei dem bei der Herstellung des Ge häuses das Herstellungswerkzeug in Richtung der Stutzenachse entformt werden soll. In diesem Fall dürfen an dem Umfang des Stutzens keine nach radial außen abstehenden Vorsprünge vor handen sein.The invention addresses the problem through a such trigger protection the manufacture of a housing with egg not adversely affect the outwardly projecting nozzle sen. This applies in particular to a housing with a protruding Plastic nozzle, in which in the manufacture of the Ge housing the production tool in the direction of the nozzle axis should be removed from the mold. In this case, the scope of the No protrusions protruding radially outwards be there.
Die vorstehende Problematik wird mit einer Ausführung der gattungsgemäßen Abzugsicherung nach den kennzeichnenden Merk malen des Anspruchs 1 gelöst. The above problem is solved with an execution of the Generic deduction protection according to the characteristic note paint the claim 1 solved.
Bei dieser Lösung müssen in dem Stutzen lediglich fensterar tige Öffnungen für das Einführen vorgespannter Rastnasen vor gesehen werden, was fertigungstechnisch rationell möglich ist.With this solution, only need to be windowed in the nozzle openings for the insertion of pre-tensioned locking lugs be seen what is rationally possible in terms of production technology is.
Der erfindungsgemäß vorgesehene in dem Gehäuse-Stutzen zu fi xierende Träger ermöglicht es ferner in recht vorteilhafter Weise, an diesem ohne direkte Anbindung an dem Gehäuse ein im Inneren des Gehäuses vorzusehendes Funktionsteil zu befesti gen oder als integrales Teil zusammen mit diesem herzustel len. Ein solches Funktionsteil kann beispielsweise eine im Öffnungsbereich des Stutzens innerhalb des Gehäuses vorzuse hende Strömungsleitwand sein.The provided in the housing neck to fi xier carrier also allows it in quite advantageous Way, on this one without a direct connection to the housing Functional part to be provided inside the housing gene or as an integral part together with this len. Such a functional part can, for example, be a Opening area of the nozzle within the housing current flow baffle.
Eine Abzugsicherung als Rastverbindung zwischen dem Stutzen eines Gehäuses und einem auf diesen aufschiebbaren Rohrkanal läßt sich mit Bezug auf den Rohrkanal recht vorteilhaft durch eine dort eingeformte umlaufende Rille verwirklichen. Auf diese Weise ist eine dichte Anlage am Ende des aufzustecken den Rohrkanales gegenüber dem Gehäuse-Stutzen auf einfache, und sichere Weise möglich.A trigger protection as a snap connection between the nozzle a housing and a pipe channel that can be pushed onto it can be quite advantageous with respect to the pipe duct realize a circumferential groove formed there. On this way, a tight system is to be plugged in at the end of the the pipe duct compared to the housing socket in a simple, and safe way possible.
Die Rastverbindung zwischen dem Gehäuse-Stutzen und dem auf zuschiebenden Rohrkanal kann ohne das Entfernen eines Raste lementes gelöst werden, wodurch kein für die Rastverbindung notwendiges Funktionselement bei gelöster Rastverbindung ver loren gehen kann. The snap connection between the housing socket and the Sliding pipe channel can be done without removing a catch lementes be solved, which means no for the locking connection necessary functional element with detached locking connection ver can go loren.
Insbesondere der zuletzt genannte Vorteil besteht bei einer Abzugsicherung zwischen einem Rohr und einem Rohrstutzen nach GB 2 119 123 A nicht. Für die Rastverbindung ist dort eine lose aufsetzbare Spange erforderlich, die beim Lösen der Rastverbindung von den miteinander zu verbindenden Teilen ab getrennt werden muß mit dem obengenannten Nachteil, daß sie leicht verloren gehen kann. Des weiteren kann der Rohrkanal nicht von außen auf den Gehäuse-Stutzen aufgeschoben werden, sondern muß in diesen eingesteckt werden. Ferner ist es bei jener bekannten Ausführung nicht möglich, ein im Inneren des Gehäuses vorzusehendes Funktionsteil in die Rastverbindungse lemente zu integrieren.In particular, the last-mentioned advantage is one Deduction protection between a pipe and a pipe socket GB 2 119 123 A does not. There is one for the snap connection loosely attachable clip required when loosening the Snap connection from the parts to be connected must be separated with the above disadvantage that they can easily get lost. Furthermore, the pipe channel must not be pushed onto the housing connector from the outside, but must be plugged into it. It is also at that known version not possible, one inside the Housing functional part to be provided in the locking connections to integrate elements.
Bei der erfindungsgemäßen Lösung kann der Träger für die Rastnasen ein Ring oder auch eine ringförmige Spange sein. Die Spange muß dabei lediglich eine solche Umfangslänge be sitzen, daß eine axiale Fixierung innerhalb des Gehäuse- Stutzens, in die sie eingeschoben ist, sichergestellt ist.In the solution according to the invention, the carrier for the Lugs can be a ring or an annular clip. The clip only has to be such a circumferential length sit that an axial fixation within the housing Socket into which it is inserted is ensured.
Ein Ausführungsbeispiel ist in der Zeichnung dargestellt.An embodiment is shown in the drawing.
Diese zeigt
einen Schnitt durch einen Gehäuseausschnitt
mit einem nach außen abragenden Stutzen, auf
dem ein Rohrkanal abzuggesichert aufgesteckt
ist.
This shows
a section through a housing cutout with an outwardly projecting nozzle on which a pipe duct is attached secured against withdrawal.
In die Gehäusewand 1 eines lediglich bereichsweise darge stellten Gehäuses ist ein nach außen abragender Stutzen 2 eingeformt. Das Gehäuse und der Stutzen 2 sind aus Kunst stoff.In the housing wall 1 of a housing presented only in regions Darge 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 ent formt wird.The housing is produced together with the connector 2 in a tool which is ent formed in the direction of the axis of the socket. 2
In den Stutzen 2 ist ein Träger 3 mit einem ringförmigen Bund 4 eingeschoben. Der Ringbund 4 besitzt radial federnd ange formte Zungen 5 mit an den freien Enden radial abstehenden Rastnasen 6. Die Rastnasen 6 durchdringen in dem Stutzen 2 vorgesehene Fenster 7, aus denen sie nach außen herausragen.A support 3 with an annular collar 4 is inserted into the socket 2 . The annular collar 4 has radially resiliently shaped tongues 5 with radially projecting locking lugs 6 at the free ends. The locking lugs 6 penetrate in the connector 2 provided windows 7 , from which they protrude outwards.
Auf den Stutzen 2 ist ein Rohrkanal 8 aufgeschoben. Zur Er zielung einer gewünschten Abzugsicherung ist in das aufge schobene Ende der Wand des Rohrkanales 8 eine umlaufende Ril le 9 eingeformt. Mit dieser Rille 9 verrastet der aufgescho bene Rohrkanal 9 an den Rastnasen 6. Der über die Umfangsril le 9 axial zum aufgeschobenen Ende des Rohrkanales 8 hinaus ragende 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 is a circumferential Ril le 9 is formed in the pushed up end of the wall of the pipe channel 8 . With this groove 9, the pushed-open pipe channel 9 latches on the locking lugs 6 . The over the circumferential groove 9 axially to the pushed end of the pipe channel 8 also 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 Strö mungsleitwand 10 angeformt und kann dadurch ohne direkte An formung an das Gehäuse bzw. die Gehäusewand 1 im Inneren des Gehäuses gehalten werden. Das Gehäuse kann beispielsweise bei einem Kraftfahrzeug 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 thereby be held in the interior of the housing without direct shaping to the housing or the housing wall 1 . In a motor vehicle, for example, the housing can be 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.
