Abstract
Description
Die Erfindung betrifft eine Anschlussverbindung zwischen einem Nippel und einem Gegenelement. Derartige Verbindungen werden im Sanitärbereich häufig verwendet. An dem Nippel ist eine Überwurfmutter angebracht, die an dem Nippel mit einer in Axialrichtung wirkenden Schulter an einer Gegenschulter des Nippels anliegt und in ein Gewinde des Gegenelements eingeschraubt wird. Aufgrund der Anlageschulter der Überwurfmutter muss diese von dem dem freien Ende des Nippels entgegengesetzten Ende auf das den Nippel enthaltende Element aufgesetzt werden, was bei Schläuchen oder Leitungen beispielsweise möglich sein kann. Falls dies aber nicht möglich ist, muss an dem Nippel mit Abstand von dessen freien Ende ein Einstich beziehungsweise eine Nut vorhanden sein, in die erst nach dem Aufschieben der Überwurfmutter ein Spannring eingesetzt wird. Dies bedeutet aber, dass ausreichend Platz in Axialrichtung vorhanden sein muss, da die Überwurfmutter von dem freien Ende her soweit aufgeschoben werden muss, dass der Einstich zum Einsetzen des Spannrings frei liegt.The The invention relates to a connection between a nipple and a counter element. Such compounds are used in the sanitary sector often used. On the nipple a union nut is attached, the on the nipple with an axially acting shoulder on one Counter-shoulder of the nipple rests and in a thread of the counter-element is screwed in. Due to the contact shoulder of the union nut this must be opposite from the free end of the nipple End are placed on the nipple containing element, which with hoses or lines, for example, possible can be. If this is not possible, it must be on the nipple at a distance from the free end of a puncture or a groove be present in the after the sliding of the nut a clamping ring is used. This means that there is enough space must be present in the axial direction, since the union nut of the free End must be postponed so far that the puncture to Inserting the clamping ring is exposed.
Der Erfindung liegt die Aufgabe zu Grunde, eine Anschlussverbindung zu schaffen, die auch bei geringerem zur Verfügung stehenden Platz verwendbar ist.Of the Invention is based on the object, a connection connection to create that even with less available space usable is.
Zur Lösung dieser Aufgabe schlägt die Erfindung eine Anschlussverbindung mit den im Anspruch 1 genannten Merkmalen vor. Weiterbildungen der Erfindung sind Gegenstand von Unteransprüchen.to solution this task strikes the invention a connection with the connection mentioned in claim 1 Characteristics. Further developments of the invention are the subject of Dependent claims.
Das den Nippel enthaltende Bauteil enthält also statt eines Einstichs einen umlaufenden Vorsprung, der ein Gewinde aufweist. Die Axialerstreckung dieses Vorsprungs kann sehr kurz sein, da eigentlich eine Gewindewindung schon ausreicht. Die entsprechende Erstreckung des mit diesem Gewindevorsprung zusammenwirkenden Gewindes der Überwurfmutter kann ebenfalls kurz sein. Die Überwurfmutter wird von dem freien Ende des Nippels auf diesen aufgeschoben und über den Gewindevorsprung hinweg aufgeschraubt. Die dem freien Ende des Nippels abgewandte Seite dieses Gewindevorsprungs bildet die Anlageschulter des Nippels, und die dem freien Ende der Überwurfmutter zugewandte Seite des entsprechenden Gewindeabschnitts der Überwurfmutter bildet ebenfalls die Anlageschulter. Die Überwurfmutter muss gerade soweit aufgeschraubt werden, bis sie hinter dem Gewindevorsprung greift. Dadurch verringert sich die erforderliche Baulänge in axialer Richtung in beachtlichem Ausmaß.The The nipple containing component thus contains instead of a puncture a circumferential projection having a thread. The axial extension This projection can be very short, since actually a thread already sufficient. The corresponding extent of this thread projection co-operating thread of the union nut can also be short. The union nut is pushed from the free end of the nipple on this and over the Screwed thread projection across. The the free end of the nipple opposite side of this thread projection forms the contact shoulder of the nipple, and the free end of the nut facing side the corresponding threaded portion of the nut also forms the contact shoulder. The union nut must be screwed just enough to the point behind the thread projection attacks. This reduces the required length in the axial Direction to a considerable extent.
In Weiterbildung der Erfindung kann vorgesehen sein, dass die beiden Gewinde der Überwurfmutter einen axialen Abstand aufweisen. Dieser axiale Abstand ist vorzugsweise so groß, wie die axiale Länge des Gewindevorsprungs des Nippels.In Further development of the invention can be provided that the two Thread of the union nut have an axial distance. This axial distance is preferably so big like the axial length the thread projection of the nipple.
Es ist ebenfalls oder auch alternativ möglich, dass die beiden Gewinde der Überwurfmutter unterschiedlichen Durchmesser aufweisen.It is also or alternatively possible that the two threads the union nut have different diameters.
Da die beiden Gewindeabschnitte der Überwurfmutter nicht zusammenwirken, können sie auch unterschiedliche Gewindesteigungen aufweisen.There the two threaded sections of the union nut do not interact, can they also have different thread pitches.
Da normalerweise bei handelsüblichen Sanitärverbindungen Rechtsgewinde verwendet werden, kann erfindungsgemäß vorgesehen sein, dass das mit dem Gewindevorsprung des Nippels zusammenwirkende Innengewinde der Überwurfmutter ein Linksgewinde ist. Bei besonderen Verhältnissen kann dies auch umgekehrt sein.There usually at commercial sanitary connections Right-hand thread can be used according to the invention be that cooperating with the thread projection of the nipple Internal thread of the union nut is a left-hand thread. In special circumstances, this can be reversed be.
