Abstract
Description
Die Erfindung betrifft eine Anschlußklemme für ein elektrisches Installationsgerät gemäß dem Oberbegriff des Anspruches 1. Eine derartige Anschlußklemme ist aus EP 0 809 325 bekannt.The invention relates to a terminal for an electrical installation device according to the preamble of claim 1. Such a terminal is known from EP 0 809 325.
Anschlußklemmen in elektrischen Installationsgeräten, insbesondere in Leitungsschutzschaltern, Fehlerstromschutzschaltern und dgl., dienen dazu, elektrische Anschlußleiter in Form von Rundleitern, Litzenleitern oder Flachbandleitern an das Installationsgerät anzuschließen.Terminals in electrical installation equipment, especially in circuit breakers, residual current circuit breakers and the like. Serve to connect electrical leads in the form of round conductors, stranded conductors or ribbon conductors to the installation device.
Bei üblichen Leitungsschutzschaltern ist eine Anschlußklemme vorgesehen, die einen kastenförmigen Klemmrahmen aufweist, dessen die Klemmschraube aufnehmende Wand durch zwei übereinandergeklappte Stegenden gebildet sind. An den Stegenden sind Vorsprünge vorgesehen, die in die Seitenwände des Klemmrahmens eingedrückt werden, damit der Klemmrahmen sich beim Verklemmen nicht verformt, siehe z. B. EP 0 454 019 A1.In conventional circuit breakers, a terminal is provided which has a box-shaped clamping frame, the clamping screw receiving wall are formed by two superimposed folded web ends. At the web ends projections are provided which are pressed into the side walls of the clamping frame, so that the clamping frame does not deform when jammed, see, for. EP 0 454 019 A1.
Aus der WO 88/07772 ist eine Anschlußklemme vorgesehen, bei der ein im Querschnitt rechteckiges Schmiedeteil vorgesehen ist, das eine Innendurchführung aufweist, die einen Gewindeabschnitt besitzt, in den eine Bolzenschraube eingeschraubt werden kann, wobei als Betätigungswerkzeug beispielsweise ein Innensechskantwerkzeug Verwendung finden kann.From WO 88/07772 a terminal is provided in which a rectangular cross-section forging is provided which has an internal passage, which has a threaded portion into which a bolt screw can be screwed, which can be used as an operating tool, for example, a hexagon socket tool.
Bei dieser Anordnung ist es nicht möglich, sowohl Rundraht-, Litzenleiter als auch Flachbandleiter anzuschrauben bzw. anzuklemmen.In this arrangement, it is not possible to screw or clamp both stranded wire, stranded wire and ribbon cable.
Aus der DE 196 21 194 A1 ist eine Anschlußklemme der eingangs genannten Art bekannt geworden, die eine zylinderförmigen Klemmkörper aufweist, der an seinem einen Ende ein Innengewinde zur Aufnahme einer Klemmschraube besitzt und darüber hinaus axiale Durchbrüche oder Schlitze an den diametral sich gegenüberliegenden Wandabschnitten aufweist, durch die der Raum zugänglich ist, in dem eine Anklemmung erfolgt.From DE 196 21 194 A1, a terminal of the aforementioned type has become known, which has a cylindrical clamping body, which has at its one end an internal thread for receiving a clamping screw and also has axial openings or slots on the diametrically opposite wall sections, through which the room is accessible, in which a Anklemmung takes place.
Bei den bekannten Anschlußklemmen drückt sich die Stirnseite der Klemmschraube auf den Leiter, was beim Festklemmen wegen der sich drehenden Klemmschraube insbesondere bei feindrähtigen Leitern zu einer Beschädigung derselben führen kann. Darüber hinaus kann sich der Klemmrahmen bzw. der Klemmkörper verdrehen und dabei ein Drehmoment auf die Klemme ausüben, so daß das Gehäuse des Installationsgerätes, in das die Anschlußklemme eingesetzt wird, aufgeweitet oder gar beschädigt werden kann. Darüber hinaus besteht das Problem, daß die Klemmschraube beim Herausschrauben aus dem Klemmrahmen herausgedreht werden kann. Dabei kann sie Verkippen, wodurch beim Wiederanziehen Probleme entstehen, oder ans Gehäuse stoßen, was ebenfalls zu Beschädigungen führen kann.In the known terminals, the end face of the clamping screw presses on the conductor, which can lead to damage during clamping because of the rotating clamping screw, especially in finely stranded conductors. In addition, the clamping frame or the clamping body can rotate while exerting a torque on the terminal, so that the housing of the installation device, in which the terminal is used, can be widened or even damaged. In addition, there is the problem that the clamping screw can be unscrewed when unscrewing from the clamping frame. It can tilt, causing problems when re-tightening, or encounter the housing, which can also lead to damage.
Aufgabe der Erfindung ist es, eine Anschlußklemme der eingangs genannten Art zu schaffen, bei der eine Beschädigung des Gehäuses sowie ein vollständiges Herausdrehen der Klemmschraube sicher vermieden werden kann.The object of the invention is to provide a terminal of the type mentioned, in which damage to the housing and a complete unscrewing the clamping screw can be safely avoided.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1 gelöst.This object is achieved by the features of claim 1.
Dadurch, daß am inneren Ende der Klemmschraube eine in die Durchbrüche zur axialen Führung eingreifenden Ansätze aufweisende Druckplatte vorgesehen ist, die gegenüber der Klemmschraube drehbar an dieser festgelegt ist, wird zunächst vermieden, daß beim Festklemmen feindrähtiger Leiter diese Leiter beschädigt werden.Characterized in that at the inner end of the clamping screw engaging in the apertures for axial guidance lugs pressure plate is provided which is rotatably fixed relative to the clamping screw on this, it is initially avoided that these conductors are damaged when clamping fine stranded conductor.
Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung kann der Innengewindeabschnitt des Klemmkörpers in einem Abstand von der oberen Stirnseite des Klemmkörpers enden, der geringfügig größer ist als der axiale Gewindebereich der Klemmschraube; der Innendurchmesser dieses gewindefreien Abschnittes ist dabei geringfügig größer als der Außendurchmesser der Klemmschraube, so daß nach Herausschrauben der Klemmschraube aus dem Innengewindeabschnitt das Klemmschraubengewinde in den gewindefreien Abschnitt des Klemmkörpers gelangt und dieser die Klemmschraube außerhalb des Innengewindeabschnittes führt.According to a further advantageous embodiment of the invention, the female threaded portion of the clamping body may terminate at a distance from the upper end side of the clamping body, which is slightly larger than the axial threaded portion of the clamping screw; the inner diameter of this unthreaded portion is slightly larger than the outer diameter of the clamping screw, so that after unscrewing the clamping screw from the female threaded portion, the clamping screw thread enters the unthreaded portion of the clamp body and this leads the clamping screw outside of the female threaded portion.
Gemäß einer weiteren Ausgestaltung der Erfindung kann die Länge der die Druckplatte aufnehmenden und führenden Schlitze am Klemmkörper so bemessen sein, daß dann, wenn die Klemmschraube in den gewindefreien Abschnitt des Klemmkörpers gelangt, sich die Druckplatte gegen die betätigungsseitigen Schlitzenden anlegt.According to a further embodiment of the invention, the length of the pressure plate receiving and leading slots on the clamp body be sized so that when the clamping screw enters the unthreaded portion of the clamp body, the pressure plate against the actuating side slot ends applies.
Damit wird erreicht, daß auch bei vollständigem Herausschrauben der Klemmschraube aus dem Innengewinde des Klemmkörpers ein Verkanten der Klemmschraube vermieden wird, so daß beim Wiederanziehen der klemmschraube problemlos ein Eingriff des Außengewindes der klemmschraube in das Innengewinde des Klemmkörpers ermöglicht wird. Dabei wird durch das Anlegen der Druckplatte an die Schlitzenden ein Herausfallen der Klemmschraube verhindert.This ensures that even with complete unscrewing of the clamping screw from the internal thread of the clamp body tilting the clamping screw is avoided, so that when re-tightening the clamping screw easily engagement of the external thread of the clamping screw is made possible in the internal thread of the clamp body. In this case, falling out of the clamping screw is prevented by the application of the pressure plate to the slot ends.
Gemäß einer weiteren Ausgestaltung der Erfindung kann gemäß Anspruch 5 die Druckplatte durch einen Nietvorgang an der Klemmschraube festgelegt werden, wobei die Druckplatte relativ zur Klemmschraube drehbar ist.According to a further embodiment of the invention, according to claim 5, the pressure plate can be fixed by a riveting operation on the clamping screw, wherein the pressure plate is rotatable relative to the clamping screw.
Gemäß einer weiteren Ausgestaltung der Erfindung können das Innengewinde des Klemmkörpers und das Außengewinde der Klemmschraube als Sägezahngewinde ausgebildet sein, wobei gemäß einer weiteren Ausführungsform der Erfindung die etwa radial verlaufende Flanke zur Klemmstelle hingerichtet ist bzw. in Klemmrichtung weist.According to a further embodiment of the invention, the internal thread of the clamping body and the external thread of the clamping screw may be formed as Sägezahngewinde, wherein according to a further embodiment of the invention, the approximately radially extending edge is executed to the nip or points in the clamping direction.
Weitere vorteilhafte Ausgestaltungen und Verbesserungen der Erfindung sind den weiteren Unteransprüchen zu entnehmen.Further advantageous embodiments and improvements of the invention can be found in the further subclaims.
Anhand der Zeichnung, in der ein Ausführungsbeispiel der Erfindung dargestellt ist, sollen die Erfindung sowie weitere vorteilhafte Ausgestaltungen und Verbesserungen der Erfindung und weitere Vorteile näher erläutert und beschrieben werden.Reference to the drawing, in which an embodiment of the invention is shown, the invention and further advantageous refinements and improvements of the invention and other advantages will be explained and described in detail.

Die in der Fig. 1 dargestellte Anschlußklemme 10 besitzt einen zylindrischen Klemmkörper 11, der zwei diametral sich gegenüber liegende Schlitze 12, die axial verlaufen, aufweist, von denen lediglich einer der Schlitze sichtbar ist.The
Die Innenfläche des zylindrischen Klemmkörpers 11 besitzt zwischen den Schlitzen 12 auf sich diametral gegenüber liegenden Innenwandabschnitten Innengewindebereiche 13, die durch Eindrücken von außen gebildet sind, was in der Fig. 1 anhand der axial verlaufenden Vertiefung 14 erkennbar ist. In den Innengewindeabschnitt 13, der in Abstand L vom oberen Ende des Klemmkörpers 11 (siehe Fig. 4), abschließt, ist eine Stift-Schraube 15 eingeschraubt, deren inneres Ende einen Fortsatz 16 mit verringertem Durchmesser aufweist, an den sich eine Nietung 17 mit gegenüber dem Vorsprung oder Fortsatz 16 größeren Durchmesser ausschließt, wobei sich in dem Abschnitt zwischen der Klemmschraube 15 und der Nietung 17 eine Druckplatte 18 befindet, welches eine nicht dargestellte Bohrung besitzt, in der die Druckplatte als das Druckstück 18 mittels der Nietung vernietet ist. Das Druckstück 18 greift dabei in die axial verlaufenden Schlitze 12 beidseitig ein, so daß es in den Schlitzen 13 durch deren axiale Längskanten 19, 20 axial geführt ist.The inner surface of the
An dem in der Fig. 1 unteren Ende, also an demjenigem Ende, das der Einschraubrichtung entgegengesetzt liegt, besitzt der quer zur Längsachse verlaufende untere Rand 20 eine Lasche 21, die ins Innere des Klemmkörpers 11 eingebogen ist und senkrecht zur Mittelachse des Klemmkörpers verläuft. An den Außenflächen, etwa in einer Linie mit den Vertiefungen 14 für die Innengewindeabschnitte 13, sind axial verlaufende Vorsprünge 23, 24 angeformt, die in entsprechenden Vertiefungen an einem Gehäuse, in das die Klemme 10 eingesetzt ist und z. B. das Gehäuse eines Leitungsschutzschalters oder Fehlerstromschutzschalters sein kann, geführt ist. Dadurch wird ein Mitdrehen des Klemmrahmens beim Anziehen der Klemmschraube verhindert und die Kraft definiert in das Gehäuse eingeleitet und ein Auseinanderklaffen verhindert.At the lower end in FIG. 1, that is to say at the end opposite the screwing-in direction, the
In den Zwischenraum zwischen den Längskanten 19 und 20 ist ein Klemmstück 25 eingesetzt, welches U-förmig ausgebildet ist und zwei quer zur Mittelachse des Klemmkörpers 11 verlaufende Schenkel 26 und 27 besitzt, wobei an dem Schenkel 26 senkrecht zu diesem und parallel zur Mittelachse des Klemmkörpers 11 eine Anschlußlasche 28 angeformt ist, an der Anschlußelemente für im Inneren des Installationsgerätes befindliche Komponenten befestigt sind. Zwischen den beiden Schenkeln 26 und 27 befindet sich ein Druckelement 29, damit die beiden Schenkel 26 und 27 beim Festziehen der Klemmschraube nicht aufeinander zu verformen.In the space between the
Auf der oberen Seite des Schenkel 26 befindet sich eine quer zum Schenkel 26 verlaufende Leiste 30, und an der dem Schenkel 26 zugewandten Seite des Druckstückes 18 zwei dazu parallele Druckstückleisten 31, 32, die quer zum Verlauf eines eingeführten Leitungsdrahtes angeordnet sind und auf diese Weise ein Herausziehen des Leitungsdrahtes verhindern. In Fig. 3 ist auch ersichtlich der Randbord 17 zur Fixierung der Schraube 15.On the upper side of the
In Fig. 4 ist nun ein Teil des Klemmkörpers 11 dargestellt, bei dem ersichtlich ist, daß der Innengewindeabschnitt 13 in dem Abstand L von der oberen Stirnfläche endet, so daß an der Innenfläche des Klemmkörpers ein gewindefreier Abschnitt 33 vorgesehen ist, dessen Innendurchmesser bis hin zum Rand des Klemmkörpers dem Außendurchmesser der Schraube 15 entspricht, so daß in diesem Abschnitt die Schraube 15 geführt ist. Damit wird erreicht, daß beim Wiedereindrehen der Schraube 15 das Außengewinde der Schraube 15 sofort mit dem Innengewinde 13 kämmt. Beim Herausdrehen der Klemmschraube läuft die Klemmschraube aus dem Innengewinde des klemmkörpers heraus, bevor die Druckplatte an den Rahmen anstößt, und die Druckplatte dient dazu, ein Herausfallen der Klemmschraube zu verhindern.In Fig. 4, a part of the
Die Fig. 2 zeigt den Einbau der klemmschraube 10 in ein Gehäuseteil 40, das mit einem entsprechenden schalenförmigen Gehäuseteil (nicht gezeigt) zu einem Leitungsschutzschaltergehäuse ergänzt wird. Dieses Gehäuseteil 40 besitzt einen klemmenaufnahmeraum 41, dessen Länge und Innendurchmesser der Anschlußklemme 10 angepaßt ist. Von der Frontseite 62 her besitzt das Gehäuse 40 eine kreisförmige Öffnung 43, durch die ein Werkzeug zu der Schraube 15 hindurch geführt werden kann. Auf den sogenannten Schmalseitenflächen 44 des Gehäuseteils sind Durchbrechungen 45 und 46 vorgesehen, durch die in Pfeilrichtung P1 bzw. P2 Anschlußleiter zur Klemmschraube eingeführt werden können. Dabei ist die Anordnung so gewählt, daß durch den Durchbruch 46 eine Anschlußfahne für eine Sammelschiene einführbar ist, wogegen durch den Durchbruch 45 ein Runddraht oder Litzendraht angeschlossen werden kann.Fig. 2 shows the installation of the
Das Gehäuseteil 40 wird ergänzt durch ein gleich ausgebildetes Gehäuseteil, bei dem die in der Fig. 2 dargestellten Hälften der Durchbrüche 43, 45 und 46 zu "geschlossenen" Durchbrüchen ergänzt werden, so daß sich im montierten Zustand eine kreisförmige Öffnung 43, eine rechteck-förmige Öffnung 45 und eine rechteck-förmige Öffnung 46 ergeben.The
