Description

Elektrische Anschlussklemme zur Durchführung einer Leitung durch eine Wandung Electrical connection terminal for conducting a cable through a wall
Die Erfindung betrifft eine elektrische Anschlussklemme zum Durchführen einer Leitung durch eine Wandung, mit einer ersten Klemme zur Anbringung an einer Seite der Wandung und einer zweiten Klemme zur Anbringung an der anderen Seite der Wandung.The invention relates to an electrical terminal for passing a line through a wall, having a first terminal for attachment to one side of the wall and a second terminal for attachment to the other side of the wall.
Elektrische Anschlussklemmen haben in verschiedenen Anwendungsgebieten, wie in der industriellen Verbindungstechnik, eine große Bedeutung und dienen beispielsweise zum An- Schluss von elektrischen Komponenten. Elektrische Anschlussklemmen der in Rede stehenden Art sind vorzugsweise für Geräte mit abgeschlossenen Gehäusen entwickelt worden und als sogenannte Durchführungsklemmen zur Durchführung einer Leitung durch eine Wandung des Gehäuses bekannt.Electrical connection terminals have great significance in various fields of application, such as in industrial connection technology, and are used, for example, to connect electrical components. Electrical terminals of the type in question have preferably been developed for devices with enclosed housings and known as so-called lead-through terminals for carrying a line through a wall of the housing.
Aus dem Stand der Technik sind Durchführungsklemmen bekannt, bei denen die erste Klemme in einem Innenbereich des Gehäuses als Innenklemme und die zweite Klemme in einem Außenbereich des Gehäuses als Außenklemme zu liegen kommt. Ferner sind aus dem Stand der Technik Durchführungsklemmen bekannt, bei denen ein an der Innenseite des Gehäuses vorgesehenes Isolierteil der Außenklemme entgegenwirkt. Vielfach weisen die Innenklemme und/oder die Außenklemme einen Schraubanschlusskörper, einen Anschlussstift, einen Lötan- schluss, einen Flachsteckanschluss oder einen Wickelanschluss zur Kontaktierung der Leitung auf.Feedthrough terminals are known from the prior art, in which the first terminal comes to lie in an inner region of the housing as an inner terminal and the second terminal in an outer region of the housing as an outer terminal. Furthermore, from the prior art bushing terminals are known in which a provided on the inside of the housing insulating part of the outer terminal counteracts. In many cases, the inner terminal and / or the outer terminal on a Schraubanschlusskörper, a pin, a Lötan- circuit, a blade terminal or a winding connection for contacting the line.
Die bekannten, zuvor erläuterten Durchführungsklβmmen sind in erster Linie für Mess- und Regelstromkreise verwendbar, nämlich bis maximal 660 V und 20 A erhältlich. Höhere Spannungen bzw. Ströme erfordern eine deutliche Vergrößerung der Klemmen, um die normgemäß erforderlichen Luft- und Kriechstrecken zu erreichen. Derartige aus dem Stand der Tech- nik bekannte Durchführungsklemmen, die für höhere Spannungen, wie beispielsweise 1000 V, verwendbar sind, sind fertigungstechnisch jedoch nur extrem aufwändig zu produzieren und sind aufgrund der deutlich vergrößerten Volumina der Klemmen nicht universell einsetzbar.The known, previously explained Durchführungsklβmmen are primarily used for measurement and control circuits, namely up to a maximum of 660 V and 20 A available. Higher voltages or currents require a significant increase in the terminals in order to achieve the required air and creepage distances according to standards. Such prior art nik known feedthrough terminals, which can be used for higher voltages, such as 1000 V, manufacturing technology, however, are extremely expensive to produce and are not universally applicable due to the significantly increased volumes of terminals.
Daher ist es die Aufgabe der Erfindung, eine kompakte elektrische Anschlussklemme zum Durchführen einer Leitung durch eine Wandung anzugeben, die für hohe Spannungen bzw. Ströme verwendbar ist.Therefore, it is the object of the invention to provide a compact electrical terminal for passing a line through a wall, which is suitable for high voltages or currents.
Diese Aufgabe wird gelöst durch eine elektrische Anschlussklemme zum Durchführen einer Leitung durch eine Wandung, mit einer ersten Klemme zur Anbringung an einer Seite der Wandung und einer zweiten Klemme zur Anbringung an der anderen Seite der Wandung, wobei die erste Klemme ein Verbindungselement zum Verbinden mit der zweiten Klemme aufweist, das Verbindungselement in die zweite Klemme einführbar ist, die zweite Klemme eine Stromschiene zur elektrischen Verbindung mit der ersten Klemme aufweist, die Stromschiene in das Verbindungselement einführbar ist, und die der Stromschiene abgewandte O- berfläche des Verbindungselements eine Kriechstromverlängerung aufweist.This object is achieved by an electrical connection terminal for passing a line through a wall, having a first terminal for attachment to one side of the wall and a second terminal for attachment to the other side of the wall, the first terminal having a connection element for connection to the wall second terminal, the connecting element is insertable into the second terminal, the second terminal has a busbar for electrical connection to the first terminal, the busbar is insertable into the connecting element, and the busbar facing away O- berfläche of the connecting element has a creepage current extension.
Erfindungsgemäß wird damit eine derartige elektrische Anschlussklemme zum Durchführen einer Leitung durch eine Wandung angegeben, die für höhere Spannungen, wie beispielsweise 1000 V, verwendbar ist, ohne dass die Volumina der Klemmen gegenüber den aus dem Stand der Technik bekannten Ausgestaltungen für elektrische Anschlussklemmen geringerer Spannungen vergrößert sind. Dadurch, dass die der Stromschiene abgewandte Oberfläche des Verbindungselements eine Kriechstromverlängerung aufweist, erlaubt die erfindungsgemäße e- lektrische Anschlussklemme die Durchführung einer höheren Spannung, wie beispielsweise 1000 V, durch eine Wandung bei Einhaltung der nach Norm erforderlichen Luft- und Kriechstrecken, wie beispielsweise aus Norm IEC 60947-7-1/DESf EN 60664- 1/VDEO 110-1 ersichtlich. Vorzugsweise ist die gesamte der Stromschiene abgewandte Oberfläche des Verbindungselements, also die Oberfläche des Verbindungselements, die nicht der Stromschiene zugewandt ist, als Kriechstromverlängerung ausgeführt. Dabei weist die Oberfläche der erfindungsgemäßen Kriechstromverlängerung eine größere Kriechstrecke auf, als eine Oberfläche des Ver- bindungselements ohne Kriechstromverlängerung, wie insbesondere eine Oberfläche mit ebener Form. Ferner ist bevorzugt, dass die Stromschiene als Strombalken geführt ist, wobei das Verbindungselement vorzugsweise ein isolierendes Material aufweist. Weiterhin ist bevorzugt, dass die erste Klemme an einer Innenseite der Wandung als Innenklemme und die zweite Klemme an der Außenseite der Wandung als Außenklemme befestigbar ist. Die erfin- dungsgemäße Kriechstromverlängerung kann insbesondere die Kriechstrecke eines Kriechstroms verlängern, der zwischen der Stromschiene und der Wandung fließt. Dabei kann die Wandung beispielsweise ein metallisches, also leitfähiges Material aufweisen und Teil eines Gehäuses, wie einer elektrischen Installationsdose oder eines Schaltschranks, sein.According to the invention, such an electrical connection terminal is specified for carrying out a line through a wall, which can be used for higher voltages, such as 1000 V, without increasing the volumes of the terminals compared with the designs for electrical connection terminals of lower voltages known from the prior art are. The fact that the busbar facing away from the surface of the connecting element has a leakage current extension, the inventive e lectric connection terminal allows the implementation of a higher voltage, such as 1000 V, by a wall in compliance with the required air clearance and creepage distances, such as standard IEC 60947-7-1 / DESf EN 60664-1 / VDEO 110-1. Preferably, the entire surface of the connecting element facing away from the busbar, that is to say the surface of the connecting element which does not face the busbar, is designed as a leakage current extension. In this case, the surface of the creepage current extension according to the invention has a greater creepage distance than a surface of the connecting element without creepage current extension, in particular a surface with a planar shape. Furthermore, it is preferred that the busbar is guided as a current bar, wherein the connecting element preferably comprises an insulating material. Furthermore, it is preferred that the first terminal on an inner side of the wall as an inner terminal and the second terminal on the outside of the wall is attachable as an outer terminal. In particular, the creepage current extension according to the invention can extend the creepage distance of a leakage current which flows between the busbar and the wall. In this case, the wall may for example have a metallic, that is to say conductive material and be part of a housing, such as an electrical installation box or a control cabinet.
Grundsätzlich kann die Kriechstromverlängerung geometrisch beliebig ausgestaltet sein. Gemäß einer bevorzugten Weiterbildung der Erfindung ist jedoch vorgesehen, dass die Kriech- stromverlängerung eine abwechselnd nutartige und federartige Strukturierung und/oder eine zahnartige Strukturierung der der Stromschiene abgewandten Oberfläche des Verbindungselements aufweist. Weiterhin ist bevorzugt, dass die Kriechstromverlängerung eine eckenarti- ge Strukturierung und/oder eine rippenartige Strukturierung aufweist. Eine derartige Kriechstromverlängerung vergrößert die Kriechstrecke, so dass die erfindungsgemäße elektrische Anschlussklemme mit höheren Spannungen beaufschlagbar ist.In principle, the creepage current extension can be configured geometrically as desired. According to a preferred embodiment of the invention, however, it is provided that the creepage current extension has an alternating groove-like and spring-like structuring and / or a tooth-like structuring of the surface of the connecting element facing away from the busbar. Furthermore, it is preferred that the creepage current extension has a corner-like structuring and / or a rib-like structuring. Such creepage current extension increases the creepage distance, so that the electrical connection terminal according to the invention can be subjected to higher voltages.
Ganz besonders ist bevorzugt, dass das Verhältnis der Tiefe der Nut zu der Höhe der Feder der abwechselnd nutartigen und federartigen Strukturierung in einem vorderen Abschnitt des Verbindungselements größer ist als in einem hinteren Abschnitt des Verbindungselements. Dabei ist der vordere Abschnitt des Verbindungselements tiefer in die zweite Klemme einführbar ist als der hintere Abschnitt des Verbindungselements. Durch eine derartige Ausges- - A -It is particularly preferred that the ratio of the depth of the groove to the height of the spring of the alternating groove-like and spring-like structuring in a front portion of the connecting element is greater than in a rear portion of the connecting element. In this case, the front portion of the connecting element is inserted deeper into the second terminal than the rear portion of the connecting element. Due to such a - A -
taltung lässt sich erreichen, dass in dem Bereich des Verbindungselements, der am weitesten in die zweite Klemme ausgeführt ist, die Kriechstrecke des Kriechstroms gegenüber dem Bereich des Verbindungselements, der weniger weit in die zweite Klemme eingeführt ist, verlängert ist.It can be achieved that, in the region of the connecting element which is furthest into the second terminal, the creepage distance of the leakage current is prolonged in relation to the region of the connecting element which is inserted less far into the second terminal.
Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung ist bei miteinander verbundener erster Klemme und zweiter Klemme mindestens der vordere Abschnitt des Verbindungselements in die zweite Klemme eingeführt. Mit anderen Worten kann ein Kriechstrom zwischen der Stromschiene und der Wandung auf der der Stromschiene abgewandten Ober- fläche des vorderen Abschnitts des Verbindungselements fließen, wobei der vordere Abschnitt des Verbindungselements eine Kriechstromverlängerung aufweist. In diesem Zusammenhang ist gemäß einer Weiterbildung der Erfindung bevorzugt, dass in dem vorderen Abschnitt des Verbindungselements die gesamte der Stromschiene abgewandte Oberfläche des Verbindungselements eine abwechselnd nutartige und federartige Strukturierung aufweist. Mit anderen Worten weist das Verbindungselement mindestens in dem vorderen Abschnitt eine das Verbindungselement umlaufend umfassende abwechselnd nutartige und federartige Strukturierung auf, welche die der Stromschiene abgewandte Oberfläche des Verbindungselements bedeckt.According to a further preferred embodiment of the invention, when the first terminal and the second terminal are connected to one another, at least the front section of the connecting element is inserted into the second terminal. In other words, a leakage current can flow between the busbar and the wall on the surface of the front section of the connecting element facing away from the busbar, wherein the front section of the connecting element has a leakage current extension. In this context, it is preferred according to a development of the invention that in the front portion of the connecting element, the entire surface of the connecting element facing away from the busbar has an alternating groove-like and spring-like structuring. In other words, at least in the front section, the connecting element has an alternating groove-like and spring-like structuring surrounding the connecting element, which covers the surface of the connecting element facing away from the busbar.
Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung weist die zweite Klemme ein Rastelement zum Verrasten des Verbindungselements auf, wobei das Rastelement dem Verbindungselement entgegenwirkt und das Rastelement in dem an die Wandung angrenzenden Bereich der zweiten Klemme angeordnet ist. Durch eine derartige Ausgestaltung wird es ermöglicht, dass zum einen das Verbindungselement durch das Rastelement beim Verbinden der ersten Klemme mit der zweiten Klemme geführt wird, und zum anderen die Klemme mit der zweiten Klemme durch das Rastelement mit dem Verbindungselement verrastbar ist. Gemäß einer bevorzugten Weiterbildung der Erfindung ist ferner vorgesehen, dass im Bereich der Wandung das Verbindungselement zumindest teilweise in das Rastelement einführbar ist. Mit anderen Worten ist bevorzugt, dass das Rastelement nicht nur in dem an die Wandung angrenzenden Bereich der zweiten Klemme angeordnet ist, sondern auch mindestens teilweise oder vollständig in den Bereich der Wandung aus der zweiten Klemme herausragt. Eine derartige Ausgestaltung erlaubt eine weitere Verlängerung der Kriechstrecke, da die Kriechstrecke zusätzlich zu der Kriechstromverlängerung um die Länge des in den Bereich der Wandung hereinragenden Rastelements verlängert ist.According to a further preferred embodiment of the invention, the second clamp has a latching element for latching the connecting element, wherein the latching element counteracts the connecting element and the latching element is arranged in the adjoining the wall region of the second terminal. By such a configuration, it is possible that, on the one hand, the connecting element is guided by the locking element when connecting the first terminal to the second terminal, and on the other hand, the terminal is latched to the second terminal by the locking element with the connecting element. According to a preferred embodiment of the invention it is further provided that in the region of the wall, the connecting element is at least partially insertable into the locking element. In other words, it is preferred that the latching element is arranged not only in the region of the second terminal adjacent to the wall, but also protrudes at least partially or completely into the region of the wall from the second clamp. Such a configuration allows a further extension of the creepage distance, since the creepage distance is extended in addition to the creepage current extension by the length of the latching element projecting into the area of the wall.
Weiterhin ist es gemäß einer Weiterbildung der Erfindung besonders bevorzugt, dass bei miteinander verbundener erster Klemme und zweiter Klemme der vordere Abschnitt des Verbindungselements derart durch das Rastelement hindurch in die zweite Klemme eingeführt ist, dass nur der hintere Abschnitt des Verbindungselements zumindest teilweise an dem Rastelement anliegt. Mit anderen Worten ist es damit bevorzugt, dass nicht der vordere Abschnitt des Verbindungselements an dem Rastelement anliegt, sondern der hintere Abschnitt des Verbindungselements zumindest teilweise an dem Rastelement anliegt. Aufgrund dieses erfindungsgemäßen Merkmals kann erreicht werden, dass die Kriechstrecke verlängert wird, da die erfindungsgemäße Kriechstromverlängerung, welche vorzugsweise an dem vorderen Abschnitt des Verbindungselements angebracht ist, bei miteinander verbundener erster Klemme und zweiter Klemme über das Rastelement hinaus in die zweite Klemme eingeführt ist.Furthermore, according to a development of the invention, it is particularly preferred that, when the first terminal and the second terminal are connected together, the front section of the connecting element is inserted into the second terminal through the detent element such that only the rear section of the connecting element bears at least partially against the detent element , In other words, it is thus preferred that not the front portion of the connecting element rests against the latching element, but the rear portion of the connecting element at least partially rests against the latching element. Due to this inventive feature can be achieved that the creepage distance is extended because the creepage current extension according to the invention, which is preferably attached to the front portion of the connecting element is inserted at interconnected first terminal and second terminal on the locking element out in the second terminal.
Grundsätzlich kann das Rastelement beliebig ausgebildet sein.

Somit lässt sich das Verbindungselement in die das Rastelement aufweisende zweite Klemme derart einführen, dass das Rastelement mit dem hinteren Abschnitt des Verbindungselementes mittels der korrespondierenden Federn bzw.
