Abstract
Description
Die vorliegende Erfindung betrifft einen Leiteranschluß, insbesondere für Hochstromklemmen, mit einer Stromschiene, einem sie umgebenden, eine Leiteraufnahme definierenden Klemmkörper und einem Klemmorgan.The present invention relates to a conductor connection, in particular for high-current terminals, with a busbar, a clamping body surrounding it, defining a conductor receptacle, and a clamping member.
Bei bekannten Leiteranschlüssen der gattungsgemäßen Art (DE-AS 20 39 054, DE-AS 21 59 739) tritt, wie allgemein in der Anschlußtechnik üblich, die Stromschiene von der einen Seite her in den Klemmkörper ein, während der anzuschließende Leiter von der anderen, der sogenannten Leitereinsteckseite her, in den Klemmkörper eingesteckt wird. Zur Tätiaunc des Anschlusses werden dann innerhalb des umgebenden Klemmkörpers der Leiter und das betroffene Stromschienenende mit einem Klemmorgan, normalerweise einer mit einem Druckstück ausgerüsteten Klemmschraube, gegeneinander festgelegt.In known conductor connections of the generic type (DE-AS 20 39 054, DE-AS 21 59 739), as is common in connection technology, the busbar enters the clamping body from one side, while the conductor to be connected from the other, the so-called conductor insertion side, into which the clamping body is inserted. For the purpose of the connection, the conductor and the end of the conductor rail concerned are then fixed to one another within the surrounding clamping body with a clamping member, normally a clamping screw equipped with a pressure piece.
Es hat sich dabei gezeigt, daß, da große Leiterquerschnitte zu handhaben sind, oftmals die Einführung des Leiters in den-Klemmkörper problemvoll ist, und zwar besondere dann, wenn diese Leiter mehrfach gebogen, ausgerichtet und eingefädelt werden müssen.It has been shown that, since large conductor cross sections have to be handled, the introduction of the Conductor in the clamping body is problematic, especially when these conductors have to be bent, aligned and threaded several times.
Es kann außerdem bei derartigen Leiteranschlüssen der Betrieb mit Wechselstrom, insbesondere im höheren Stromstärkenbereich, durchaus problematisch werden, und zwar dann, wenn der Klemmkörper aus einem ferromagnetischen Material, wie beispielsweise Stahl, besteht und er als magnetisch geschlossenes System anzusehen ist. Es können dann beträchtliche Induktionsströme auftreten, die zu einer Erwärmung des Klemmkörpers führen und auch den Durchgangswiderstand negativ beeinflussen. Es besteht von daher die Notwendigkeit, z.B. paramagnetische Werkstoffe für eine sinnvolle Problemlösung einzusetzen. Induktive Effekte werden dadurch zwar verringert, aber nicht beseitigt. Die Verwendung derartiger Werkstoffe führt zudem zu höheren Herstellkosten und gleichzeitig zur Verringerung der mechanischen Sicherheit. Es ist dabei daran zu denken, daß gerade zur Festlegung von Leitern im höheren Durchmesserbereich über das Klemmsystem beträchtliche Klemmkräfte aufgebracht und aufrechterhalten werden müssen. Von daher ist also die Verwendung beispielsweise eines Klemmkörpers aus Stahl sehr vorteilhaft.It can also be quite problematic with such conductor connections, the operation with alternating current, especially in the higher current range, when the clamping body consists of a ferromagnetic material, such as steel, and it is to be regarded as a magnetically closed system. Considerable induction currents can then occur, which lead to heating of the clamping body and also negatively influence the volume resistance. There is therefore a need, e.g. to use paramagnetic materials for a sensible problem solving. Inductive effects are reduced, but not eliminated. The use of such materials also leads to higher manufacturing costs and at the same time to a reduction in mechanical safety. It should be borne in mind that considerable clamping forces have to be applied and maintained precisely for fixing conductors in the larger diameter range via the clamping system. Therefore, the use of a steel clamping body, for example, is very advantageous.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Leiteranschluß der gattungsgemäßen Art zu schaffen, der sowohl eine sehr einfache Handhabung bei der Leitereinführung gewährleistet wie auch zugleich Erwär- mungen des Klemmkörpers beim Wechselstromsystem vermeidet.The present invention has for its object to provide a wire connection of the generic type which ensures both a very simple handling during wire insertion, as well as at the same time heat up mun g s of the clamping body at the AC system avoids.
Die erfindungsgemäße Lösung besteht darin, daß das Ende der Stromschiene rückgebogen ist und nur die Rückbiegung, von der Leitereinsteckseite her, in dem Klemmkörper angeordnet ist.The solution according to the invention is that the end of the conductor rail is bent back and only the back bend, from the conductor insertion side, is arranged in the clamping body.
Diese, die Herstellung der Stromschiene nur unwesentlich verteuernde Ausgestaltung löst zugleich das Problem der Handhabung wie auch das der Erwärmung. Dank dieser Ausgestaltung nämlich fließt der Strom, der vom Leiter über die Leitereinsteckseite her in den Klemmkörper eintritt, auch auf der gleichen Seite wieder aus dem Klemmkörper heraus, und nicht mehr, wie bisher, auf der anderen Klemmkörperseite, an der bislang die Stromschiene aus dem Klemmkörper austrat. Hieraus resultiert eine Kompensation der elektromagnetischen Wirkung auf das Klemmsystem. Selbst wenn also ferromagnetische Materialien eingesetzt werden, entsteht im Endergebnis kein elektromagnetischer Induktionsstrom mehr. Das Klemmsystem unterliegt selbst bei Betrieb mit Wechselstrom relativ großer Stromstärken einer deutlich verringerten Erwärmung und es hat auch einen deutlich verringerten Durchgangswiderstand. Man kann daher im Endergebnis den Leiteranschluß insgesamt entweder geringer dimensionieren als bisher, oder aber ihn bei Beibehaltung der bisherigen Dimensionen elektrisch höher belasten. Die Beibehaltung ferromagnetischer Werkstoffe, insbesondere Stahl, gewährleistet eine hohe mechanische Stabilität und die Möglichkeit, hohe Klemmkräfte dauerhaft aufzubringen.This design, which is only insignificantly more expensive to manufacture the conductor rail, solves both the problem of handling and that of heating. Thanks to this configuration, the current that enters the clamp body from the conductor via the conductor insertion side also flows out of the clamp body on the same side, and no longer, as previously, on the other clamp body side, on which the busbar has hitherto been used Clamping body emerged. This results in a compensation of the electromagnetic effect on the clamping system. So even if ferromagnetic materials are used, the end result is no longer an electromagnetic induction current. The clamping system is subject to significantly reduced heating even when operated with alternating current of relatively large current intensities, and it also has a significantly reduced volume resistance. In the end result, the conductor connection can therefore either be dimensioned less overall than before, or it can be subjected to higher electrical loads while maintaining the previous dimensions. The retention of ferromagnetic materials, especially steel, ensures high mechanical stability and the possibility of permanently applying high clamping forces.
Auch die Handhabung eines derartigen Anschlusses ist außerordentlich vereinfacht. Da ja nunmehr die allein im Klemmkörper befindliche Rückbiegung der Stromschiene und der Leiter von ein und derselben Seite her in den Klemmkörper eintreten, kann man bei Betätigung des Anschlusses zunächst ungehindert den Leiter auf die Rückbiegung der Stromschiene auflegen und dann erst anschließend den Klemmkörper über die beiden aufeinanderliegenden Teile schieben und die Klemmung dann vornehmen. Der Kontaktbereich ist also während der Montage uneingeschränkt zugänglich.The handling of such a connection is also extremely simplified. Now that alone In the clamping body located back bend of the busbar and the conductor enter the clamping body from one and the same side, you can first place the conductor on the back bend of the busbar unhindered when operating the connection and only then push the clamping body over the two parts lying on top of each other and the Then carry out clamping. The contact area is therefore fully accessible during assembly.
Ein Ausführungsbeispiel eines derartigen Leiteranschlusses wird nachstehend unter Bezugnahme auf die beigefügte Zeichnung näher beschrieben.An embodiment of such a conductor connection is described below with reference to the accompanying drawings.
Die Zeichnung zeigt einen derartigen Leiteranschluß mit Schnittdarstellung des Klemmkörpers.The drawing shows such a conductor connection with a sectional view of the clamping body.
Der Leiteranschluß beinhaltet einen Klemmkörper 1, der als durch entsprechende Biegungen geschlossener Bügel aus Stahl ausgebildet ist. Oberseitig ist in den Klemmkörper 1 als Klemmorgan eine Klemmschraube 2 eingeschraubt, deren Klemmwirkung durch ein ihr zugeordnetes Druckstück 3 zu verstärken ist.The conductor connection includes a clamping body 1, which is designed as a steel bracket closed by corresponding bends. At the top, a
Zu dem Anschluß gehört ferner eine Stromschiene 4, deren mit dem Klemmkörper 1 zusammenwirkendes Ende eine Umbie- gung 5 aufweist. Unter Rückbiegung ist in diesem Zusammenhang jedwede Art einer nach rückwärts gerichteten Winkelung am Ende der Stromschiene zu verstehen. Die Rückbiegung kann sowohl durch ein tatsächliches rückwärtiges Umbiegen des Stromschienenendes gebildet sein, wie auch durch das Befestigen eines entsprechenden Win- kels am Ende einer geraden, nicht gebogenen Stromschiene.Also belongs to the terminal, a busbar 4, which cooperates with the clamping member 1 end Umbie- un g a g 5 has. In this context, backbend is to be understood as any kind of rearward-facing angulation at the end of the busbar. The Reverse bend may be formed either by an actual bending of the rear end of the busbar, as well as by attaching a corresponding W domestic kels at the end of a straight, non-bent current bar.
Der Klemmkörper 1 definiert zugleich eine Aufnahme für den anzuschließenden Leiter 6. Dieser Leiter 6 wird in den Klemmkörper 1 immer von einer bestimmten Seite her, der sogenannten Leitereinsteckseite, eingesteckt. Die Anordnung ist so getroffen, daß die Rückbiegung 5 der Stromschiene 4, und zwar nur diese Rückbiegung 5, von der Leitereinsteckseite her in den Klemmkörper 1 weist. Der sich bei dieser Ausgestaltung ergebende Verlauf des Stromes nach Tätigung des Leiteranschlusses ist mit Pfeilen in der Zeichnung illustriert. Es zeigt sich, daß dank dieser Ausgestaltung der Strom, der vom Leiter in die Stromschiene fließt, auf genau der gleichen Seite aus dem Klemmkörper 1 herausfließt, auf der er auch hineinfließt.The clamping body 1 also defines a receptacle for the conductor 6 to be connected. This conductor 6 is always inserted into the clamping body 1 from a certain side, the so-called conductor insertion side. The arrangement is such that the back bend 5 of the busbar 4, and only this back bend 5, points from the conductor insertion side into the clamping body 1. The course of the current resulting from this configuration after the conductor connection has been activated is illustrated by arrows in the drawing. It can be seen that, thanks to this configuration, the current flowing from the conductor into the conductor rail flows out of the clamping body 1 on exactly the same side on which it also flows.
Die Anschauung der Zeichnung zeigt ferner, daß die Handhabung bei Tätigung des Leiteranschlusses außerordentlich vereinfacht ist. Irgendwelche Einfädelungen der anzuschließenden Leiter vor dem Anschluß entfallen. Für die Montage kann das anzuschließende Leiterende auf die Rückbiegung 5 der Stromschiene 4 gelegt werden und gemeinsam auf beide Teile kann dann, bezogen auf die Stromschiene 4 praktisch von innen her, der Klemmkörper 1 auf die beiden Teile geschoben und die Klemmung dann durchgeführt werden.The view of the drawing also shows that handling when the conductor connection is made is extremely simplified. Any threading of the conductors to be connected before the connection is omitted. For the assembly, the end of the conductor to be connected can be placed on the back bend 5 of the busbar 4 and then jointly on both parts, based on the busbar 4 practically from the inside, the clamping body 1 can be pushed onto the two parts and the clamping can then be carried out.
Induktionsströme mit entsprechender Erwärmung und Verringerung des Durchgangswiderstandes sind auch dann nicht zu befürchten, wenn alle Teile des Klemmsystems in aus Gründen der mechanischen Sicherheit und in aus Gründen der Erzielung einer hohen Klemmkraft zu bevorzugenden Weise vollständig aus Stahl bestehen.There is also no need to fear induction currents with corresponding heating and a reduction in volume resistance if all parts of the clamping system consist entirely of steel in a manner preferred for reasons of mechanical safety and in order to achieve a high clamping force.
Da in sehr vielen Anwendungsfällen das andere Ende der Stromschiene in gleicher Weise als Leiteranschluß ausgebildet ist, ist dann zweckmäßigerweise auch das andere Ende der Stromschiene mit einer entsprechenden Rückbiegung 5 versehen, die in genau der gleichen Weise mit einem weiteren entsprechenden Klemmkörper 1 zusammenwirkt. Die Anwendung eines derartigen Leiteranschlusses beschränkt sich nicht auf Hochstromklemmen, insbesondere Hochstromreihenklemmen. Vergleichbare, mit dieser Ausgestaltung gelöste Probleme sind auch im Anwendungsbereich der Sicherungshalter bei verschiedenen Sammelschienensystemen anzutreffen.Since the other end of the busbar is formed as a lead terminal in the same way in many applications, is then also expediently the other end of the busbar with a corresponding R ückbiegung 5 is provided which cooperates in exactly the same manner with an additional corresponding clamping body. 1 The use of such a conductor connection is not limited to high-current terminals, in particular high-current terminal blocks. Comparable dissolved with this configuration problems are also within the scope of Sicherun shalter g at different busbar systems encountered.
Der Biegevorgang an den Stromschienenenden kann zweckmäßig mit einem Bearbeitungsvorgang kombiniert werden, mit dem eine Leiterabzugsicherung gebildet wird, z.B. in Form einer Riffelung der Stromschienenfläche oder eines Klemmhakens an der Stirnkante der Stromschiene.The bending process at the busbar ends can expediently be combined with a machining process with which a conductor pull-off protection is formed, e.g. in the form of a corrugation of the conductor rail surface or a clamping hook on the front edge of the conductor rail.
