Description

Die Erfindung betrifft ein Steckelement zum mechanischen Fixieren von Rohren oder dergleichen an einem Gehäuse oder dergleichen sowie zum Bereitstellen eines Anschlusses für die Kontaktierung eines Schutzleiters, umfassend einen U-förmigen Bügel, wobei dem U-förmigen Bügel ein Anschlussmittel zugeordnet ist.The invention relates to a plug-in element for mechanically fixing pipes or the like to a housing or the like and for providing a connection for contacting a protective conductor, comprising a U-shaped bracket, wherein the U-shaped bracket is associated with a connection means.

Solche Steckelemente kommen in vielen industriellen Bereich zum Einsatz. Beispielhaft sind elektronische Durchlauferhitzer genannt, in denen die Steckelemente zum Fixieren von Rohren oder dergleichen benutzt werden. Die Steckelemente dienen in erster Linie dazu, Rohre, Rohranschlüsse, Leitungen oder dergleichen mechanisch an einem Gehäuse, einem Trag- oder Stützelement oder dergleichen zu fixieren, ohne die Drehung der Rohre oder dergleichen zu behindern. Mit anderen Worten sind die Steckelemente durch ihre klammerartige Ausbildung in der Lage, die Rohre oder dergleichen einerseits zu fixieren und andererseits das freie Drehen der Rohre oder dergleichen zuzulassen. Des Weiteren dienen die Steckelemente dazu, die elektrische Kopplung bzw. Kontaktierung eines Schutzleiters zu ermöglichen. Die Steckelemente können aber genauso gut dazu dienen, feststehende, nicht drehbare Rohre oder dergleichen gleichzeitig zu fixieren und eine elektrische Kopplung/Kontaktierung herzustellen.Such plug-in elements are used in many industrial areas. By way of example, electronic water heaters are mentioned, in which the plug-in elements are used for fixing pipes or the like. The male members serve primarily to mechanically fix pipes, pipe fittings, pipes or the like to a housing, a support or support member or the like, without obstructing the rotation of the pipes or the like. In other words, the plug-in elements by their bracket-like training in a position to fix the pipes or the like on the one hand and on the other hand allow the free rotation of the tubes or the like. Furthermore, the plug-in elements serve to enable the electrical coupling or contacting of a protective conductor. But the plug-in elements can just as well serve to fix fixed, non-rotatable tubes or the like at the same time and to produce an electrical coupling / contacting.

Diese zwei Funktionen werden im Stand der Technik bisher auf unterschiedliche Weise gewährleistet. So kann die mechanische Fixierung z.B. durch eine erste Klammer sichergestellt werden, während die elektrische Kopplung durch eine zweite separate Klammer erfolgt. Diese Lösung führt jedoch zu einer erhöhten Teilevielfalt und eine aufwendige Montage. Eine andere Lösung sieht vor, dass die mechanische Fixierung durch eine Klammer erfolgt, während ein elektrischer Anschluss durch ein an das Rohr oder dergleichen angelötetes Bauteil, wie z.B. Stecker, Klemme oder Schraube, hergestellt wird. Auch diese Lösung erfordert jedoch zusätzliche Montageschritte. Um die beiden Funktionen in einem Steckelement zu vereinen, ist auch ein Steckelement mit den Merkmalen des Oberbegriffs des Anspruches 1 bekannt. Durch das beschriebene Kombinationsteil wird durch den U-förmigen Bügel die mechanische Sicherung erreicht, während die Anschlussfahne den Anschluss des Schutzleiters ermöglicht. Die bekannte Lösung weist jedoch den Nachteil auf, dass beide genannten Funktionen durch einen einzigen U-förmigen Bügel realisiert werden, was dazu führt, dass keine der beiden Funktionen optimal realisiert ist. Mit anderen Worten ist entweder die mechanische Fixierung unzureichend oder die elektrische Kontaktierung unzuverlässig.These two functions have hitherto been ensured in different ways in the prior art. Thus, the mechanical fixation can be ensured, for example, by a first clamp, while the electrical coupling is effected by a second separate clamp. However, this solution leads to an increased variety of parts and a complex installation. Another solution provides that the mechanical fixation by a clamp, while an electrical connection is made by a soldered to the pipe or the like component, such as plug, clamp or screw. However, this solution also requires additional assembly steps. In order to combine the two functions in a plug-in element, a plug-in element with the features of the preamble of claim 1 is also known. By the described combination part, the mechanical securing is achieved by the U-shaped bracket, while the terminal lug allows the connection of the protective conductor. However, the known solution has the disadvantage that both functions mentioned are realized by a single U-shaped bracket, which means that neither of the two functions is optimally realized. In other words, either the mechanical fixation is insufficient or the electrical contact is unreliable.

Es ist daher Aufgabe der vorliegenden Erfmdung, ein einfaches und leicht handhabbares Steckelement zu schaffen, das sowohl die mechanische Fixierung als auch die elektrische Kontaktierung zuverlässig gewährleistet.It is therefore an object of the present invention to provide a simple and easy-to-handle plug-in element that reliably ensures both the mechanical fixation and the electrical contacting.

Diese Aufgabe wird durch ein Steckelement der eingangs genannten Art dadurch gelöst, dass das Steckelement einen zweiten U-förmigen Bügel aufweist, der mit dem ersten U-förmigen Bügel verbunden ist. Damit wird auf überraschend einfache und sichere Weise ein Steckelement geschaffen, dass beide Funktionen optimal erfüllt. Durch das Vorhandensein von zwei U-förmigen Bügel kann einerseits eine funktionale Trennung vorgenommen werden, indem ein Bügel zur sicheren Fixierung und der andere Bügel für eine optimale elektrische Kontaktierung dient. Andererseits können trotzdem beide Funktionen durch ein einziges Bauteil realisiert werden.This object is achieved by a plug-in element of the type mentioned above in that the plug-in element has a second U-shaped bracket which is connected to the first U-shaped bracket. This creates a plug-in element in a surprisingly simple and secure manner that optimally fulfills both functions. Due to the presence of two U-shaped brackets on the one hand a functional separation can be made by a bracket for secure fixing and the other bracket is used for optimum electrical contact. On the other hand, both functions can still be realized by a single component.

Vorzugsweise ist das Steckelement als Federelement ausgebildet, wodurch insbesondere ein verbesserter elektrischer Kontakt herstellbar ist.Preferably, the plug-in element is designed as a spring element, whereby in particular an improved electrical contact can be produced.

Eine zweckmäßige Weiterbildung zeichnet sich dadurch aus, dass die beiden U-förmigen Bügel bzw. die durch sie definierten Ebenen E1 und E2 im Wesentlichen parallel zueinander angeordnet sind. Diese Ausbildung bzw. Anordnung erleichtert das Aufstecken des Steckelementes auf das Rohr oder dergleichen, wodurch die Handhabung verbessert ist.An expedient development is characterized in that the two U-shaped brackets or the planes E 1 and E 2 defined by them are arranged substantially parallel to one another. This training or arrangement facilitates Attaching the plug-in element on the pipe or the like, whereby the handling is improved.

Vorteilhafterweise sind einem der U-förmigen Bügel mindestens zwei elektrische Anschlussfahnen zugeordnet. Damit kann das Steckelement zusätzlich als Verteiler dienen.Advantageously, at least two electrical terminal lugs are assigned to one of the U-shaped brackets. Thus, the plug element can additionally serve as a distributor.

Eine bevorzugte Weiterbildung ist dadurch gekennzeichnet, dass mindestens einer der beiden U-förmigen Bügel an mindestens einem der beiden Schenkel eine Ausnehmung zur Bildung eines Schnappverschlusses aufweist. Dadurch wird erreicht, dass das Steckelement einerseits einfach aufgesteckt und andererseits zur höheren Sicherheit schwerer abzuziehen ist.A preferred development is characterized in that at least one of the two U-shaped brackets has at least one of the two legs a recess for forming a snap closure. This ensures that the plug element on the one hand simply plugged and on the other hand is harder to deduct for greater security.

Weitere vorteilhafte oder zweckmäßige Merkmale und Ausgestaltungen ergeben sich aus den Unteransprüchen und der Beschreibung. Eine besonders bevorzugte Ausführungsform wird anhand der beigefügten Zeichnung näher erläutert. In der Zeichnung zeigt:

Further advantageous or expedient features and configurations emerge from the subclaims and the description. A particularly preferred embodiment will be explained in more detail with reference to the accompanying drawings. In the drawing shows:

Das in den Figuren dargestellte Steckelement dient zum mechanischen Fixieren von drehbaren Rohren innerhalb eines Durchlauferhitzers sowie zur Bereitstellung einer elektrischen Kontaktierung eines Schutzleiters. Selbstverständlich kann das Steckelement auch in anderen Vorrichtungen und Einrichtungen zum Fixieren von feststehenden Rohren oder dergleichen und Bereitstellen eines elektrischen Anschlusses eingesetzt werden.The plug-in element shown in the figures is used for the mechanical fixing of rotatable tubes within a water heater and for providing an electrical contact of a protective conductor. Of course, the plug-in element can also be used in other devices and devices for fixing fixed pipes or the like and providing an electrical connection.

In der Figur 1 ist ein vorzugsweise einstückiges Steckelement 10 dargestellt, das sich in abgewickeltem Zustand befindet. Bei dem gezeigten Steckelement 10 handelt es sich bevorzugt um ein Stanz-Biegeteil. Die Figur 1 zeigt das Steckelement 10 in einem Zustand nach dem Stanzen und vor dem Biegen. Das Steckelement 10 umfasst einen ersten U-förmigen Bügel 11, der zur Aufnahme und Fixierung eines (nicht dargestellten) Rohres oder dergleichen ausgebildet und eingerichtet ist. Des Weiteren weist das Steckelement 10 einen zweiten U-förmigen Bügel 12 auf, der mit dem ersten Bügel 11 verbunden ist. Dem Steckelement 10 ist weiterhin ein Anschlussmittel 13 für einen Schutzleiter oder dergleichen zugeordnet.In the FIG. 1 a preferably one-piece plug-in element 10 is shown, which is in unwound condition. The plug-in element 10 shown is preferably a stamped and bent part. The FIG. 1 shows the male member 10 in a state after punching and before bending. The plug-in element 10 comprises a first U-shaped bracket 11 which is designed and arranged for receiving and fixing a pipe (not shown) or the like. Furthermore, the plug-in element 10 has a second U-shaped bracket 12, which is connected to the first bracket 11. The plug-in element 10 is further associated with a connection means 13 for a protective conductor or the like.

Die beiden Bügel 11 und 12 sind zur Bildung einer U-förmigen Doppelklammer miteinander verbunden und gebogen (siehe insbesondere Figur 4) und zum Eingriff in korrespondierende Nuten des Rohres oder dergleichen ausgebildet und eingerichtet. Ein Verbindungssteg 14 verbindet die beiden Bügel 11, 12 derart miteinander, dass die Bügel 11, 12 beabstandet zueinander liegen. Die beiden Bügel 11, 12, die jeweils eine Ebene E1 bzw. E2 aufspannen, sind im Wesentlichen parallel zueinander angeordnet. Im Wesentlichen schließt jedoch insbesondere auch ein, dass die beiden Bügel 11, 12 ausgehend vom Verbindungssteg 14 leicht auseinander laufen können, wie es in Figur 4 angedeutet ist. Dadurch wird die Federkraft des Steckelementes 10 erhöht.The two brackets 11 and 12 are connected together to form a U-shaped double clamp and bent (see in particular FIG. 4 ) and adapted to engage in corresponding grooves of the pipe or the like and set up. A connecting web 14 connects the two brackets 11, 12 with each other such that the brackets 11, 12 are spaced from one another. The two brackets 11, 12, each spanning a plane E 1 and E 2 , are arranged substantially parallel to each other. In essence, however, also includes in particular that the two brackets 11, 12 starting from the connecting web 14 can easily diverge, as in FIG. 4 is indicated. As a result, the spring force of the plug-in element 10 is increased.

Jeder Bügel 11, 12 weist zwei Schenkel 15, 16 bzw. 17, 18 auf, die jeweils beabstandet einander gegenüber liegen. Die Schenkel 15, 16 des Bügels 11 können parallel zueinander verlaufen. Bevorzugt ist jedoch eine Anordnung, bei der die Schenkel 15, 16 ausgehend vom Verbindungssteg 14 leicht aufeinander zu verlaufen, wodurch eine höhere Haltekraft realisierbar ist. Der Abstand zwischen den beiden Schenkeln 15, 16 hängt von dem Außendurchmesser des zu fixierenden Rohres oder dergleichen ab. Die Schenkel 17, 18 des Bügels 12 verlaufen parallel zueinander, wobei auch bei dieser Anordnung eine leichte Neigung der Schenkel 17, 18 aufeinander zu möglich ist. Der Abstand der Schenkel 17, 18 hängt ebenfalls von dem Durchmesser des Rohres oder dergleichen ab, auf das das Steckelement 10 gesteckt wird. Wie insbesondere der Figur 1 zu entnehmen, ist der Abstand der Schenkel 17, 18 geringer als der Abstand der Schenkel 15, 16. Die Abstände können jedoch auch variieren und insbesondere auch gleich sein.Each bracket 11, 12 has two legs 15, 16 and 17, 18, which are each spaced from each other. The legs 15, 16 of the bracket 11 may be parallel to each other. However, preference is given to an arrangement in which the legs 15, 16 proceed slightly towards one another starting from the connecting web 14, as a result of which a higher holding force can be achieved. The distance between the two legs 15, 16 depends on the outer diameter of the pipe to be fixed or the like. The legs 17, 18 of the bracket 12 are parallel to each other, whereby in this arrangement, a slight inclination of the legs 17, 18 toward each other is possible. The distance between the legs 17, 18 also depends on the diameter of the tube or the like, on which the plug-in element 10 is inserted. How the particular FIG. 1 can be seen, the distance between the legs 17, 18 is less than the distance of Legs 15, 16. However, the distances can also vary and, in particular, be the same.

Die Dicke der Bügel 11, 12 kann gleich sein. Bevorzugt ist es jedoch, wenn der Bügel 12 zur Bereitstellung des elektrischen Anschlusses eine größere Materialstärke aufweist als der Bügel 11. Einer der Bügel 11, 12 kann auch über mindestens eine Ausnehmung im Bereich der Schenkel 15 bis 18 aufweisen. In dem gezeigten Beispiel weisen die Schenkel 17, 18 des Bügels 12, deren Abstand geringer ist als der Abstand der Schenkel 15, 16 jeweils eine Ausnehmung 19, 20 auf. Die Ausnehmungen 19, 20 liegen in der Ebene E2 und einander diametral gegenüber. Selbstverständlich können die Schenkel 15, 16 alternativ oder kumulativ auch Ausnehmungen aufweisen. Auch kann nur jeweils ein Schenkel 15 oder 16 und 17 oder 18 mit einer Ausnehmung versehen sein. Durch die Ausnehmungen 19, 20 wird eine Art Schnappverschluss gebildet, derart, dass das Rohr oder dergleichen in montiertem Zustand in den Ausnehmungen 19, 20 ruht und gegen Herausrutschen gesichert ist. Des Weiteren können die Schenkel 17, 18 des Bügels 12 ausgehend von den Ausnehmungen 19, 20 nach außen auch eine Einführhilfe aufweisen. Diese Einführhilfe wird in der gezeigten Ausführungsform durch trichterförmig in Richtung der Ausnehmungen 19, 20 verlaufende Abschrägungen 21, 22 gebildet. Selbstverständlich können die Einführhilfen auch auf andere bekannte Weise gebildet sein. Auch können die Schenkel 15, 16 des Bügels 11 ebenfalls mit solchen Einführhilfen versehen sein.The thickness of the bracket 11, 12 may be the same. However, it is preferred if the bracket 12 for providing the electrical connection has a greater material thickness than the bracket 11. One of the bracket 11, 12 may also have at least one recess in the region of the legs 15 to 18. In the example shown, the legs 17, 18 of the bracket 12, whose distance is less than the distance between the legs 15, 16 each have a recess 19, 20 on. The recesses 19, 20 are in the plane E 2 and diametrically opposite each other. Of course, the legs 15, 16 alternatively or cumulatively also have recesses. Also, only one leg 15 or 16 and 17 or 18 may be provided with a recess. Through the recesses 19, 20 a kind of snap closure is formed, such that the tube or the like rests in the mounted state in the recesses 19, 20 and secured against slipping out. Furthermore, the legs 17, 18 of the bracket 12, starting from the recesses 19, 20 outwardly also have an insertion aid. This insertion aid is formed in the embodiment shown by funnel-shaped in the direction of the recesses 19, 20 extending chamfers 21, 22. Of course, the insertion aids may be formed in other known ways. Also, the legs 15, 16 of the bracket 11 may also be provided with such insertion aids.

Das Steckelement 10 kann als Federelement ausgebildet sein. Wie bereits erwähnt, kann eine Federkraft durch die leichte geneigte Anordnung der Bügel 11, 12 zueinander aufgebracht werden. Diese Federkraft wirkt in montiertem Zustand des Steckelementes 10 in eine Richtung, die etwa senkrecht zu den Ebenen E1 bzw. E2 verläuft. Alternativ oder kumulativ kann auch eine Federkraft vorgesehen sein, die innerhalb der Ebene E1 bzw. E2 in montiertem Zustand des Steckelementes 10 senkrecht zum Rohr oder dergleichen wirkt. Diese Federkraft wird dadurch erzeugt, dass die beiden Schenkel 17, 18 des Bügels 12 einen Abstand aufweisen, der geringer ist als der Außendurchmesser des Rohres oder dergleichen, auf das das Steckelement 10 aufgesteckt wird. Verstärkt wird diese Federwirkung durch einen Schlitz 23, der in dem Verbindungssteg 14 ausgebildet ist. Der Verbindungssteg 14 erstreckt sich aus diesem Grund im Vergleich zu dem Bügel 11 weiter in den Bereich des Bügels 12 (siehe insbesondere Figuren 1 und 2). Der Schlitz 23 verläuft parallel zu den Schenkeln 17, 18.The plug-in element 10 may be formed as a spring element. As already mentioned, a spring force by the slight inclined arrangement of the bracket 11, 12 are applied to each other. This spring force acts in the mounted state of the plug-in element 10 in a direction which is approximately perpendicular to the planes E 1 and E 2 . Alternatively or cumulatively, a spring force can be provided which acts perpendicular to the pipe or the like within the plane E1 or E2 in the assembled state of the plug-in element 10. This spring force is generated in that the two legs 17, 18 of the bracket 12 have a distance which is less than the outer diameter of the tube or the like, to which the plug-in element 10 is attached. This spring effect is reinforced by a slot 23 which is formed in the connecting web 14. The connecting web 14 extends for this reason in comparison to the bracket 11 in the area of the bracket 12 (see in particular Figures 1 and 2 ). The slot 23 extends parallel to the legs 17, 18th

Das Anschlussmittel 13, das vorzugsweise dem Bügel 12 zugeordnet ist, umfasst in der beschriebenen Ausführungsform zwei Anschlussfahnen 24, 25. Das Anschlussmittel 13 kann auch eine Anschlussfahne oder mehr als zwei Anschlussfahnen aufweisen. Auch dem anderen Bügel 11, der eigentlich der mechanischen Fixierung dient, kann ein Anschlussmittel in Form einer oder mehrerer Anschlussfahnen oder dergleichen zugeordnet sein.The connecting means 13, which is preferably associated with the bracket 12, comprises in the embodiment described two terminal lugs 24, 25. The connecting means 13 may also have a terminal lug or more than two terminal lugs. Also, the other bracket 11, which actually serves the mechanical fixation, a connection means may be assigned in the form of one or more terminal lugs or the like.

Vorzugsweise besteht das Steckelement 10 aus Kupfer. Es sind aber auch andere elektrisch leitende Materialien einsetzbar. Selbstverständlich kann das Steckelement 10 auch auf andere Weise als im Stanz-Biegeverfahren hergestellt sein. Des Weiteren kann das Steckelement 10 auch aus mehreren Teilen gebildet sein.Preferably, the plug element 10 is made of copper. But there are also other electrically conductive materials used. Of course, the plug-in element 10 may also be produced in a different way than in the punch-bending process. Furthermore, the plug-in element 10 can also be formed from several parts.
