Abstract

A clamp with a housing, a contact rail and a slide having clamping jaws flanking the contact rail and an interconnecting fastener, for effecting electrical connections between spaced-apart conductors, has a guide member interposed between the housing and slide. The guide member is mounted to one of the clamping jaws and has an elongated surface in slidable engagement with a surface of the housing, a leg contacting the clamping jaws for force transmission and prevention of relative rotation of the clamping jaws, a shoulder contacting said one clamping jaw also for force transmission, a recess for receiving said one clamping jaw defined by the leg and shoulder, and releasable locking engagement means for securing the slide in a neutral position independent of the action of the fastener.

Description

Die Erfindung betrifft eine Trennklemme entsprechend dem Oberbegriff des Patentanspruches 1.The invention relates to a disconnect terminal according to the preamble of claim 1.

Mit dem verschieblich auf der Stromschiene der Trennklemme geführten Trennschieber kann eine derartige Trennklemme an einer vorbeiführenden Sammelschiene, die die Netzspannung heranführt, angeschlossen werden. Soll die Netzspannungszufuhr zu der betroffenen Trennklemme und den an sie angeschlossenen Aggregaten, Geräten u.dgl. unterbrochen werden, werden über die Klemmschraube die Klemmbacken des Trennschiebers wieder geöffnet und der Trennschieber wird in eine in das Trennklemmengehäuse zurückgezogene Stellung, in der die Klemmbacken mit der Sammelschiene nicht mehr in Berührung stehen, zurückgeschoben.With the isolating slide, which is displaceably guided on the busbar of the isolating terminal, such an isolating terminal can be connected to a passing busbar, which feeds in the mains voltage. Should the mains voltage supply to the disconnect terminal concerned and the units, devices etc. connected to it? are interrupted, the clamping jaws of the isolating slide are opened again via the clamping screw and the isolating slide is pushed back into a position retracted into the isolating terminal housing, in which the clamping jaws are no longer in contact with the busbar.

Bei den bislang bekannten Trennklemmen hat man zwar versucht, die Verschiebbarkeit des geöffneten Trennschiebers auf der Stromschiene dadurch zu verbessern, daß man eine die Klemmschraube umgebende Kunststoffbuchse an einer Leiste des Trennklemmengehäuses führt, doch kommt es auch bei dieser Ausgestaltung immer wieder noch zu Schrägstellungen und Verkantungen beim Verschieben des geöffneten Trennschiebers auf der Stromschiene. Hierbei ist zu berücksichtigen, daß der Trennschieber in geöffnetem Zustand ein lose zusammenhängendes, recht labiles Gebilde ist, weil in diesem Zustand die beiden Klemmbacken relativ lose im sie umgebenden Backenhalter liegen. Die Verschiebekraft muß darüber hinaus ja von dem an der Klemmschraube angreifenden Schraubendreher aufgebracht werden, und für das Erzeugen dieser Verschiebekraft ist, auch unter Berücksichtigung des Abstandes des Schraubendreherangriffspunktes von der Stromschiene, der Kraftangriff ungünstig.In the previously known disconnect terminals, attempts have been made to improve the displaceability of the opened disconnect slide on the busbar by leading a plastic bushing surrounding the clamping screw on a strip of the disconnect terminal housing, but this configuration also always leads to inclinations and canting when moving the opened slide switch on the power rail. It must be taken into account here that the separating slide in the open state is a loosely connected, rather unstable structure, because in this state the two clamping jaws lie relatively loosely in the jaw holder surrounding them. The displacement force must also be applied by the screwdriver acting on the clamping screw, and the force application is unfavorable for generating this displacement force, also taking into account the distance of the screwdriver point of application from the busbar.

Der vorliegenden Erfindung liegt von daher die Aufgabe zugrunde, eine Trennklemme der gattungsgemäßen Art zu schaffen, die ein leichtgängiges, zuverlässiges Verschieben des Trennschiebers zur Sammelschiene und von dort zurück ermöglicht.The present invention is therefore based on the object of creating a disconnect terminal of the generic type which enables smooth, reliable displacement of the disconnect slide to the busbar and back from there.

Die erfindungsgemäße Lösung ergibt sich aus dem kennzeichnenden Teil des Anspruches 1.The solution according to the invention results from the characterizing part of claim 1.

Durch die längliche Gleitfläche des auf die obere Klemmbacke des Trennschiebers aufgesetzten zusätzlichen und gesonderten Führungsteiles und die Führung dieser Gleitfläche am Klemmengehäuse wird der Trennschieber nunmehr relativ großflächig nicht nur an der Stromschiene, sondern auch am Klemmengehäuse geführt. Trotz des relativ labilen Zustandes des geöffneten Trennschiebers läßt sich der Trennschieber jetzt in geöffnetem Zustand einwandfrei ohne Verkantungsgefahr verschieben. Hierzu trägt auch mit bei, daß bei dieser Ausgestaltung der Kraftangriff des Schraubendrehers beim Aufbringen der Verschiebekraft nahe der neu geschaffenen Führung durch die oberseitige längliche Gleitfläche liegt.Due to the elongated sliding surface of the additional and separate guide part placed on the upper clamping jaw of the disconnect slide and the guidance of this sliding surface on the terminal housing, the separating slide is now guided over a relatively large area not only on the busbar but also on the terminal housing. Despite the relatively unstable state of the opened slide valve, the slide valve can now be moved in the open state without any risk of canting. This also contributes to the fact that in this embodiment the force applied by the screwdriver when the displacement force is applied is close to the newly created guide through the elongated sliding surface on the top.

Gemäß einer bevorzugten Ausgestaltung einer derartigen Trennklemme hintergreift das Führungsteil mit einer Abwinkelung die Klemmbacken. Einerseits läßt sich hierdurch eine besonders gute Kraftübertragung der Verschiebekraft auf die auf der Stromschiene zu verschiebenden Klemmbacken erzielen. Andererseits bietet diese Abwinkelung, wenn sie in vorteilhafter Weise mit Aufnahmen für Endbereiche der Klemmbacken versehen ist, auf sehr einfache Weise die Möglichkeit, einem ungewollten gegenseitigen Verdrehen der Klemmbacken beim Anziehen der Klemmschraube entgegenzuwirken. Dies ist von besonderem Vorteil, wenn als Klemmbacken Hohlbacken eingesetzt werden, die durchaus die Tendenz haben, beim Anziehen der Klemmschraube sich seitlich aus der Klemmenebene herauszudrehen.According to a preferred embodiment of such a disconnect clamp, the guide part engages behind the clamping jaws with an angle. On the one hand, this enables particularly good force transmission of the displacement force to be achieved on the clamping jaws to be displaced on the busbar. On the other hand, this bend, if it is advantageously provided with receptacles for end regions of the clamping jaws, offers in a very simple way the possibility of counteracting an undesired mutual turning of the clamping jaws when the clamping screw is tightened. This is of particular advantage when hollow jaws are used as clamping jaws, which have a tendency to turn laterally out of the clamping plane when the clamping screw is tightened.

Gemäß einer weiteren bevorzugten Ausführungsform ist dem Führungsteil eine weitere sehr wichtige Funktion dadurch zugeordnet, daß es hinterseitig mit einer Raste versehen ist, für die am Trennklemmengehäuse in einer der Null-Lage des Trennschiebers entsprechenden Stelle eine Rastaufnahme vorgesehen ist.According to a further preferred embodiment, the guide part is assigned a further very important function in that it is provided on the rear with a catch for which a catch is provided on the disconnect terminal housing in a position corresponding to the zero position of the disconnect slide.

Trennklemmen werden hin und wieder so angeordnet, daß sich der Trennschieber im wesentlichen senkrecht oberhalb der Sammelschiene befindet und somit in in etwa senkrechter Richtung auf diese zu und von ihr fort bewegt werden muß. Wird nun nach der Abtrennung der Trennklemme vergessen, in der Null-Lage des Trennschiebers die Klemmschraube wieder richtig anzuziehen, kommt es durchaus vor, daß der Trennschieber von selbst aus der Null-Lage infolge betriebsbedingter Erschütterungen od.dgl. wieder auf die Sammelschiene herunterfällt. Dies ist für das Bedienungspersonal mit Lebensgefahr verbunden, da dieses ja in dem Glauben, vom Netz abgetrennt zu sein, an den nachgeordneten Geräten hantiert.Disconnect terminals are sometimes arranged so that the isolating slide is located substantially vertically above the busbar and must therefore be moved towards and away from it in an approximately vertical direction. If after the disconnection of the disconnect terminal is forgotten to properly tighten the clamping screw again in the zero position of the disconnect slide, it may well happen that the disconnect slide or the like from the zero position as a result of operational vibrations. falls back onto the busbar. This is life-threatening for the operating personnel, since they believe that they are disconnected from the network and are working on the downstream devices.

Die vorgesehene Verrastung über das neu. vorgesehene Führungsteil gewährleistet, daß der Trennschieber bei einer Einbaulage oberhalb der Sammelschiene nicht unbeabsichtigt aus der Null-Lage herausfallen kann, selbst dann nicht, wenn versehentlich die Klemmschraube nicht oder nicht ordnungsgemäß angezogen wird. Die Rastkraft läßt sich ohne weiteres so bemessen, daß einerseits ein unbeabsichtigtes Herabfallen nicht möglich ist, andererseits die Verschiebbarkeit nicht beeinträchtigt wird, dies um so mehr, als auch durch die neue Ausgestaltung im Bedarfsfall eine recht hohe Verschiebekraft ohne die Gefahr des Verkantens oder Schrägstellens des Trennschiebers aufgebracht werden kann.The intended locking over the new. The guide part provided ensures that the isolating slide cannot accidentally fall out of the zero position when it is installed above the busbar, even if the clamping screw is accidentally not tightened or not properly tightened. The locking force can be easily measured so that on the one hand an unintentional falling is not possible, on the other hand the displaceability is not impaired, all the more, as well as the new design, if necessary, a very high displacement force without the risk of tilting or tilting the Slider can be applied.

Ein Ausführungsbeispiel einer derartigen Trennklemme wird nachstehend unter Bezugnahme auf die beigefügte Zeichnung beschrieben.An embodiment of such Disconnect terminal is described below with reference to the accompanying drawings.

Show it
  • 1 such a disconnect terminal in side view,
  • Fig. 2 is a single side view of the guide part of the disconnect terminal according to Fig. 1 on an enlarged scale.

Die in Fig. 1 dargestellte Trennklemme weist innerhalb ihres Isolierstoffgehäuses 1 eine Stromschiene 2 auf, auf deren einem Ende ein Anschluß 3 für einen Leiter vorgesehen ist. Auf der Stromschiene 2 ist ferner im Bereich der anderen Klemmenseite ein Trennschieber4 verschieblich angeordnet, der im wesentlichen aus einer oberen, oberhalb der Stromschiene 2 befindlichen Klemmbacke 5 und einer unteren, unterhalb der Stromschiene 2 befindlichen Klemmbacke 6 besteht, wobei zum festen Zusammenklemmen der Klemmbacken 5 und 6 auf der Stromschiene 2 und/oder einer vor einer Anreihung derartiger Trennklemmen vorbeiführenden, in Fig. 1 strichpunktiert angedeuteten Sammelschiene 7 eine Klemmschraube 8 vorgesehen ist. Die Sammelschiene 7 bringt die Netzspannung zu der Anreihung von Trennklemmen.The disconnect terminal shown in Fig. 1 has within its insulating material housing 1 a busbar 2, on one end of which a connection 3 is provided for a conductor. On the busbar 2, in the area of the other terminal side, there is also a sliding slide 4 which essentially consists of an upper jaw 5 located above the busbar 2 and a lower jaw 6 located below the busbar 2, the jaws 5 being firmly clamped together and 6, a clamping screw 8 is provided on the busbar 2 and / or a busbar 7 leading past a row of such disconnect terminals and indicated by dash-dotted lines in FIG. 1. The busbar 7 brings the line voltage to the series of disconnect terminals.

Um den Trennschieber 4, der bei gelösten Klemmbacken 5, 6 ein relativ labiles Gebilde ist, auf der Stromschiene 2 einwandfrei zur Sammelschiene 7 hin (Stellung in Fig. 1 dargestellt) oder unter Abtrennung der Trennklemme vom Netz in eine rückwärtige, in das Trennklemmengehäuse hineingeschobene Stellung leichtgängig und ohne Verkantungsgefahr verschieben zu können, ist auf der oberen Klemmbacke 5 des Trennschiebers 4 ein aus Kunststoff bestehendes Führungsteil 9 befestigt, das oberseitig eine längliche Gleitfläche 10 aufweist, die an der Innenfläche der oberen Begrenzungswand 1 des Isolierstoffgehäuses 1 geführt ist. Das Führungsteil 9 weist ferner eine Schraubendreherführungsöffnung 11 auf, die zu einer Aufnahmekammer 12 führt, in der der Schraubenkopf der Klemmschraube 8 liegt. Die Bohrungswand der Schraubendreherführungsöffnung 11, über die mittels des Schraubendrehers die Verschiebekraft für den Trennschieber 4 übertragen wird, liegt somit unmittelbar angrenzend an die obere längliche Gleitfläche 10. In der oberen Begrenzungswand 1a ist eine längliche Durchbrechung 1 b vorgesehen, in der der Schraubendreher bei einem Verschieben des Trennschiebers 4 hin- und herwandern kann.Around the isolating slide 4, which is a relatively unstable structure when the clamping jaws 5, 6 are released, on the busbar 2 properly towards the busbar 7 (position shown in FIG. 1) or with the disconnection of the isolating terminal from the mains into a rear, pushed into the isolating terminal housing To move the position smoothly and without the risk of canting, a plastic guide part 9 is attached to the upper jaw 5 of the separating slide 4 and has an elongated sliding surface 10 on the upper side, which is guided on the inner surface of the upper boundary wall 1 of the insulating housing 1. The guide part 9 also has a screwdriver guide opening 11 which leads to a receiving chamber 12 in which the screw head of the clamping screw 8 lies. The bore wall of the screwdriver guide opening 11, via which the displacement force for the separating slide 4 is transmitted by means of the screwdriver, is thus directly adjacent to the upper, elongated sliding surface 10. In the upper boundary wall 1a, an elongated opening 1b is provided, in which the screwdriver at one Moving the slide valve 4 can move back and forth.

Das Führungsteil 9 weist des weiteren eine Öffnung 13 für einen Prüfstecker auf.The guide part 9 also has an opening 13 for a test plug.

Das Führungsteil 9 ist an seinem hinteren unteren Ende mit einer nach unten weisenden Abwinkelung 14 versehen, die sowohl die obere Klemmbacke 5 wie auch die untere Klemmbacke 6 des Trennschiebers 4 hintergreift. Die Abwinkelung 14 weist eine Durchbrechung 15 auf, durch die die Stromschiene 2 hindurchtreten kann. Die Abwinkelung 14 bildet ferner durch einen seitlich angeformten, nach vorne vorspringenden Steg 16 eine Aufnahme für die hinteren Enden der oberen Klemmbacken 5 und 8, die sich seitlich mit ihren Endbereichen an den Steg 16 anlegen, dergestalt, daß sie sich beim Anziehen der Klemmschraube 8 nicht mehr seitlich aus der Klemmebene herausdrehen können, wie es insbesondere dann geschehen kann, wenn man die Klemmbacken 5 und 6 als Hohlbacken ausbildet.The guide part 9 is provided at its rear lower end with a downward-pointing bend 14 which engages behind both the upper jaw 5 and the lower jaw 6 of the separating slide 4. The bend 14 has an opening 15 through which the busbar 2 can pass. The bend 14 also forms a receptacle for the rear ends of the upper clamping jaws 5 and 8 by means of a laterally formed, forwardly projecting web 16, which abut laterally with their end regions on the web 16 in such a way that they tighten when the clamping screw 8 is tightened can no longer turn laterally out of the clamping plane, as can happen in particular when the clamping jaws 5 and 6 are designed as hollow jaws.

Das Führungsteil 9 kann auf der oberen Klemmbacke 5 festgeklemmt werden. Hierzu ist mittels einer vorderseitigen Materialschulter 17 eine Aufnahme 18 gebildet, die gegenüberliegend der Materialschulter 17 durch die infolge der Verwendung von Kunststoffmaterial begrenzt elastische Abwinkelung 14 begrenzt ist.The guide part 9 can be clamped on the upper jaw 5. For this purpose, a receptacle 18 is formed by means of a material shoulder 17 on the front side, which is delimited opposite the material shoulder 17 by the elastic bend 14, which is limited due to the use of plastic material.

Das Führungsteil 9 weist ferner eine Raste auf, mit der eine leichte Verrastung des Trennschiebers 4 in seiner Null-Lage, d.h. in der in die Klemme eingeschobenen Stellung abständig zur Sammelschiene 7 möglich ist. Hierzu ist im hinteren Bereich des Führungsteiles 9 eine Federleiste 19 angeformt, die an ihrem hinteren Ende unterseitig einen Rastnoppen 20 trägt. An dem Isolierstoffgehäuse 1 der Trennklemme ist an entsprechender Stelle ein Gegenrastkörper 21 angeformt. Die Verrastung in der Null-Lage bewirkt, daß bei einer **. Trennklemmenanordnung senkrecht oder etwa senkrecht oberhalb einer Sammelschiene der Trennschieber 4 nicht unbeabsichtigt aus der Null-Lage auf die die Netzspannung führende Sammelschiene herabfallen kann, selbst dann nicht, wenn versehentlich die Klemmschraube 8 in der Null-Lage nicht oder nicht ordnungsgemäß wieder an gezogen wurde.The guide part 9 also has a catch with which a slight latching of the isolating slide 4 in its zero position, ie in the position inserted into the clamp, is possible at a distance from the busbar 7. For this purpose, a female connector 19 is formed in the rear area of the guide part 9, which has a locking knob 20 on its underside at its rear end. A counter-latching body 21 is integrally formed on the insulating material housing 1 of the disconnect terminal. Locking in the zero position means that with a ** . Disconnect terminal arrangement vertically or approximately vertically above a busbar of the isolating slide 4 cannot inadvertently fall from the zero position onto the busbar carrying the mains voltage, even if the clamping screw 8 in the zero position was accidentally not or not properly tightened again.
