Definitions

  • the invention relates to a slide valve arrangement with two clamping pieces arranged above and below a divided busbar, between the opposite ends of which are displaceably arranged and which are traversed by a clamping screw.
  • the clamping pieces in the open position of the clamping screw i.e. with a given displacement option, have only an insufficient hold and an insufficient guidance on the opposite end regions of the split busbar. Tilting often occurs when moving and it is then difficult to close the cocking slide by pushing the clamping pieces towards the end of the previously unconnected busbar part to be acted on in the closed position.
  • a disconnect terminal in which a disconnect slide, consisting essentially of an upper and a lower clamping piece, which are crossed by a clamping screw, arranged in the terminal housing on an undivided busbar to and fro is that can be moved out of the terminal box to a passing busbar.
  • a plastic guide part is already arranged on the upper clamping piece on the upper side, which is guided with an upper sliding surface over a large area on an inner wall of the insulating material housing of this isolating terminal. This makes use of the structural option available for this type of terminal to guide the isolating slide on the insulating housing of the terminal.
  • a downward-pointing angled portion is located on the guide part, on which webs are provided which protrude from behind into the upper and lower clamping piece. This arrangement does not contribute to the guidance, but prevents the clamping pieces from turning sideways out of the clamping plane when the clamping screw is tightened.
  • An opening is provided in the bend for the passage of the undivided busbar.
  • the present invention has for its object to provide a gate valve assembly of the generic type, which ensures a heightened, tilt-free movement and a reliable fixing of the clamping pieces with a simple construction.
  • the solution according to the invention results from the characterizing part of claim 1. Thanks to the rear guide bar on one of the clamping pieces and the rear extension on the other clamping piece and the guidance of this guide bar both in an opening in the bent leg of one busbar part and behind it in the extension of the other clamping piece, the two clamping pieces now form a stable, positional composite system with a guide on the one busbar part, which can be easily and reliably tilted between the open position and the closed position of the isolating slide arrangement can move back and forth on the busbar parts.
  • clamping pieces of the separating slide arrangement with their rear guide strips or extensions are designed as one-piece, simple sheet metal bent parts.
  • the isolating slide arrangement shown includes a divided busbar with two busbar pieces 1a and 1b, which face each other in the region of the disconnection point with the ends concerned.
  • the isolating slide assembly also includes two clamping pieces arranged above and below the current rail piece 1b (open position according to FIG. 1) or above and below the two current rail pieces 1a, 1b (closed position according to FIG. 2) and displaceable between the opposite ends of the current rail pieces 1a and 1b 2a and 2b, which are crossed by a clamping screw 3.

  • a plug opening 8 is provided, into which the free end of the guide rail 4 is inserted after it has passed through the opening 6 in the leg 5 of the busbar part 1b.
  • the two clamping pieces 2a and 2b form, via the guide rail 4 and the angular extension piece 7, a stable, self-contained part assembly which, due to the guidance of the guide rail 4 in the leg 5 of the busbar part 1b, leads reliably and without canting on the busbar part 1b and without additional measures can be easily pushed onto the affected end of the busbar part 1a in the closed position (FIG. 2).

Description

Die Erfindung betrifft eine Trennschieberanordnung mit zwei oberhalb und unterhalb einer geteilten Stromschiene angeordneten, zwischen deren einander gegenüberliegenden Enden verschieblich angeordneten Spannstücken, die von einer Spannschraube durchquert sind. Bei den bekannten Trennschieberanordnungen, die vielfach bei Reihenklemmen zum Einsatz kommen (DE-B-24 30 736),haben die Spannstücke in der Offenstellung der Spannschraube, d.h. bei gegebener Verschiebemöglichkeit, nur einen unzureichenden Halt und eine unzureichende Führung auf den einander gegenüberliegenden Endbereichen der geteilten Stromschiene. Es kommt beim Verschieben vielfach zu Verkantungen und es ist dann schwierig, den Spannschieber zu schließen, in dem man die Spannstücke auf das in der Schließstellung zu beaufschlagende Ende des bislang nicht angeschlossenen Stromschienenteiles zuschieben. In begrenztem Ausmaß versucht man Abhilfe dadurch zu schaffen, daß man für die Stromschiene zumindest in diesen Endbereichen und auch für die Spannstücke besondere Profilierungen, insbesondere in Form Hinterschneidungen, vorsieht, was den konstruktiven Aufbau derartiger Blechbiegeteile erheblich verkompliziert und damit verteuert. In der Schließstellung des Trennschiebers werden bei der bisherigen Ausgestaltung bei Anziehen der Spannschraube nicht unbeträchtliche Kräfte auf beide Teile der geteilten Stromschiene aufgebracht, mit dem Ergebnis, daß beide Stromschienenteile in einem umgebenden Gehäuse od. dgl. einer besonderen verdreh- und verkantungssicheren Verankerung bedürfen. Auch dies verkompliziert und verteuert die Herstellung.The invention relates to a slide valve arrangement with two clamping pieces arranged above and below a divided busbar, between the opposite ends of which are displaceably arranged and which are traversed by a clamping screw. In the known isolating slide assemblies, which are often used with terminal blocks (DE-B-24 30 736), the clamping pieces in the open position of the clamping screw, i.e. with a given displacement option, have only an insufficient hold and an insufficient guidance on the opposite end regions of the split busbar. Tilting often occurs when moving and it is then difficult to close the cocking slide by pushing the clamping pieces towards the end of the previously unconnected busbar part to be acted on in the closed position. To a limited extent, attempts are being made to remedy this by providing special profiles, in particular in the form of undercuts, for the conductor rail, at least in these end regions and also for the clamping pieces, which considerably complicates the structural design of such bent sheet metal parts and thus makes it more expensive. In the closed position of the gate valve, the previous configuration when tightening the tensioning screw, not inconsiderable forces are applied to both parts of the divided busbar, with the result that both busbar parts or the like in a surrounding housing or the like require special twist and tilt-proof anchoring. This also complicates and increases the cost of production.

Es ist ferner aus der DE-C-31 46 914 eine Trennklemme bekannt, bei der ein Trennschieber, im wesentlichen bestehend aus einem oberen und einem unteren Spannstück, die von einer Spannschraube durchquert werden, im Klemmengehäuse auf einer ungeteilten Stromschiene hin- und herverschieblich angeordnet ist, der aus dem Klemmengehäuse heraus zu einer vorbeiführenden Sammelschiene verschoben werden kann. Um den Trennschieber einwandfrei ohne Verkantungsgefahr verschieben zu können, ist dabei bereits auf dem oberen Spannstück oberseitig ein aus Kunststoff bestehendes Führungsteil angeordnet, das mit einer oberen Gleitfläche großflächig an einer Innenwand des Isolierstoffgehäuses dieser Trennklemme geführt ist. Damit wird die bei diesem Klemmentyp baulich vorhandene Möglichkeit der Führung des Trennschiebers am Isolierstoffgehäuse der Klemme genutzt. In weiterer Ausgestaltung befindet sich an dem Führungsteil rückwärtig eine nach unten weisende Abwinklung, an der Stege vorgesehen sind, die von hinten in das obere und untere Spannstück vorstehen. Diese Anordnung trägt zur Führung nicht bei, sondern verhindert, daß beim Anziehen der Spannschraube die Spannstücke seitlich aus der Spannebene herausdrehen können. In der Abwinklung ist eine Durchbrechung für den Durchtritt der ungeteilten Stromschiene vorgesehen.It is also known from DE-C-31 46 914, a disconnect terminal, in which a disconnect slide, consisting essentially of an upper and a lower clamping piece, which are crossed by a clamping screw, arranged in the terminal housing on an undivided busbar to and fro is that can be moved out of the terminal box to a passing busbar. In order to be able to move the isolating slide properly without the risk of canting, a plastic guide part is already arranged on the upper clamping piece on the upper side, which is guided with an upper sliding surface over a large area on an inner wall of the insulating material housing of this isolating terminal. This makes use of the structural option available for this type of terminal to guide the isolating slide on the insulating housing of the terminal. In a further embodiment, a downward-pointing angled portion is located on the guide part, on which webs are provided which protrude from behind into the upper and lower clamping piece. This arrangement does not contribute to the guidance, but prevents the clamping pieces from turning sideways out of the clamping plane when the clamping screw is tightened. An opening is provided in the bend for the passage of the undivided busbar.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Trennschieberanordnung der gattungsgemäßen Art zu schaffen, die bei einfachem konstruktiven Aufbau ein gehöhtes, verkantungsfreies Bewegen und eine zuverlässige Festsetzung der Spannstücke gewährleistet. Die erfindungsgemäße Lösung ergibt sich aus dem kennzeichnenden Teil des Patentanspruches 1. Dank der rückwärtigen Führungsleiste an einem der Spannstücke und der rückwärtigen Verlängerung an dem anderen Spannstück sowie der Führung dieser Führungsleiste sowohl in einer Durchbrechung des abgebogenen Schenkels des einen Stromschienenteiles als auch dahinter in der Verlängerung des anderen Spannstückes bilden die beiden Spannstücke nunmehr ein stabiles, lagehaltiges Verbundsystem mit Führung an dem einen Stromschienenteil, das sich problemlos zuverlässig und verkantungsfrei zwischen der Offenstellung und der Schließstellung der Trennschieberanordnung auf den Stromschienenteilen hin- und herbewegen läßt. Man kann dabei trotzdem auf komplizierte Profilierungen an den Stromschienenteilen und/oder den Spannstücken verzichten. In der Schließstellung der Trennschieberanordnung bildet sich zwischen der Spannstelle und der Durchtrittsstelle der Führungsleiste durch den abgebogenen Schenkel des einen Stromschienenteiles ein kurzes, in sich geschlossenes Kräftesystem aus, das auch eine stabile Festsetzung gewährleistet. Dabei wird die gesamte Spannkraft praktisch nur von diesem einen Stromschienenteil aufgenommen, das entsprechend in einem Gehäuse oder dergleichen zu verankern ist, während das andere Teilstück der geteilten Stromschiene keiner besonderen Verankerung mehr bedarf. In weiterer zweckmäßiger Ausgestaltung braucht auch nur dieses die Spannkraft aufnehmende Stromschienenteil im Bereich des Trennschiebers mit einem Eintrittsschlitz für die Spannschraube versehen zu werden.The present invention has for its object to provide a gate valve assembly of the generic type, which ensures a heightened, tilt-free movement and a reliable fixing of the clamping pieces with a simple construction. The solution according to the invention results from the characterizing part of claim 1. Thanks to the rear guide bar on one of the clamping pieces and the rear extension on the other clamping piece and the guidance of this guide bar both in an opening in the bent leg of one busbar part and behind it in the extension of the other clamping piece, the two clamping pieces now form a stable, positional composite system with a guide on the one busbar part, which can be easily and reliably tilted between the open position and the closed position of the isolating slide arrangement can move back and forth on the busbar parts. You can still do without complicated profiles on the busbar parts and / or the clamping pieces. In the closed position of the isolating slide arrangement, a short, self-contained force system is formed between the tensioning point and the passage point of the guide rail by the bent leg of the one busbar part, which also ensures stable fixing. The entire clamping force is practically only absorbed by this one busbar part, which is to be anchored accordingly in a housing or the like, while the other section of the divided busbar no longer requires any special anchoring. In a further expedient embodiment, only this busbar part that absorbs the clamping force needs to be provided with an entry slot for the clamping screw in the region of the separating slide.

In weiterer zweckmäßiger Ausgestaltung werden die Spannstücke der Trennschieberanordnung mit ihren rückwärtigen Führungsleisten bzw. Verlängerungen als einstückige einfache Blechbiegeteile ausgebildet.In a further expedient embodiment, the clamping pieces of the separating slide arrangement with their rear guide strips or extensions are designed as one-piece, simple sheet metal bent parts.

A preferred embodiment of a slide valve arrangement according to the invention is described below with reference to the drawing.
Show it:
Figure 1
a slide valve assembly according to the invention in a perspective view in the open position of the slide valve,
Fig. 2
the slide valve assembly of FIG. 1 in the closed position of the slide valve.

Die dargestellte Trennschieberanordnung beinhaltet eine geteilte Stromschiene mit zwei Stromschienenstücken 1a und 1b, die sich im Bereich der Trennstelle mit den betroffenen Enden einander gegenüberliegen. Die Trennschieberanordnung beinhaltet ferner zwei oberhalb und unterhalb des Stromschienenstückes 1b (Offenstellung gemäß Fig. 1) bzw. oberhalb und unterhalb der beiden Stromschienenstücke 1a, 1b (Schließstellung gemäß Fig. 2) angeordnete und zwischen den einander gegenüberliegenden Enden der Stromschienenstücke 1a und 1b verschiebliche Spannstücke 2a und 2b, die von einer Spannschraube 3 durchquert sind.The isolating slide arrangement shown includes a divided busbar with two busbar pieces 1a and 1b, which face each other in the region of the disconnection point with the ends concerned. The isolating slide assembly also includes two clamping pieces arranged above and below the current rail piece 1b (open position according to FIG. 1) or above and below the two current rail pieces 1a, 1b (closed position according to FIG. 2) and displaceable between the opposite ends of the current rail pieces 1a and 1b 2a and 2b, which are crossed by a clamping screw 3.

Erfindungsgemäß hat nun im dargestellten Ausführungsbeispiel das obere Spannstück 2a einen Führungsansatz 4, der im dargestellten Ausführungsbeispiel eine rückwärtige Führungsleiste ist, wobei das Spannstück 2a mit der Führungsleiste 4 als einstückiges Blechbiegeteil ausgebildet ist.According to the invention, in the exemplary embodiment shown, the upper clamping piece 2a now has a guide projection 4, which in the exemplary embodiment shown is a rear guide strip, the clamping piece 2a being designed as a one-piece bent sheet metal part with the guide strip 4.

Die Führungsleiste 4 ist in einer Durchbrechung eines angrenzenden Elementes der Trennschieberanordnung geführt. Im dargestellten Ausführungsbeispiel bildet das entsprechende Stromschienenstück 1b der geteilten Stromschiene selbst dieses Element. Das Stromschienenstück 1b weist hierzu einen nach oben weisenden Schenkel 5 auf, der an entsprechender Stelle eine Durchbrechung 6 hat, in der die Führungsleiste 4 geführt wird.The guide bar 4 is guided in an opening in an adjacent element of the separating slide arrangement. In the exemplary embodiment shown, the corresponding busbar piece 1b of the divided busbar itself forms this element. For this purpose, the busbar piece 1b has an upwardly pointing leg 5, which corresponding point has an opening 6 in which the guide bar 4 is guided.

Das andere Spannstück 2b weist ferner eine Verlängerung auf, im dargestellten Ausführungsbeispiel ein rückwärtiges Winkelstück 7, in dessen hinteren kurzen Schenkel das hintere freie Ende der Führungsleiste 4 festgesetzt ist. Auch das Spannstück 2b mit dem rückwärtigen Winkelstück 7 ist als einstückiges Blechbiegeteil ausgebildet. In dem hochgebogenen Schenkel des Winkelstückes ist eine Stecköffnung 8 vorgesehen, in die das freie Ende der Führungsschiene 4, nach Durchtritt durch die Durchbrechung 6 im Schenkel 5 des Stromschienenteiles 1b, eingesteckt ist.The other clamping piece 2b also has an extension, in the exemplary embodiment shown a rear angle piece 7, in the rear short leg of which the rear free end of the guide bar 4 is fixed. The clamping piece 2b with the rear angle piece 7 is also formed as a one-piece bent sheet metal part. In the bent leg of the elbow, a plug opening 8 is provided, into which the free end of the guide rail 4 is inserted after it has passed through the opening 6 in the leg 5 of the busbar part 1b.

Die beiden Spannstücke 2a und 2b bilden über die Führungsschiene 4 und das winkelförmige Verlängerungsstück 7 einen stabilen insich geschlossenen Teileverbund, der sich durch die Führung der Führungsschiene 4 in dem Schenkel 5 des Stromschienenteiles 1b verkantungsfrei und zuverlässig ohne weitere zusätzliche Hilfsmaßnahmen auf dem Stromschienenteil 1b führen und problemlos in der Schließstellung (Fig. 2) auf das betroffene Ende des Stromschienenteiles 1a aufschieben läßt. In der Schließstellung (Fig. 2) bildet die Spannstelle unter Einschluß der Spannschraube 3 und der Durchtrittsbereich der Führungsleiste 4 durch den Schenkel 5 des betroffenen Stromschienenteiles ein insich geschlossenes Kraftsystem, das die Spannkraft aufnimmt. Insoweit braucht lediglich das Stromschienenteil 1b dreh- und verkantungssicher in einem angrenzenden Gehäusebereich festgelegt zu werden.The two clamping pieces 2a and 2b form, via the guide rail 4 and the angular extension piece 7, a stable, self-contained part assembly which, due to the guidance of the guide rail 4 in the leg 5 of the busbar part 1b, leads reliably and without canting on the busbar part 1b and without additional measures can be easily pushed onto the affected end of the busbar part 1a in the closed position (FIG. 2). In the closed position (FIG. 2), the tensioning point, including the tensioning screw 3 and the passage area of the guide bar 4 through the leg 5 of the busbar part concerned, forms a self-contained power system which absorbs the tensioning force. In this respect, only the busbar part 1b needs to be fixed in an adjacent housing area so that it cannot rotate and tilt.

Es braucht bei dieser Ausgestaltung auch lediglich dieses Stromschienenteil 1b in seinem Endbereich im Bereich der Trennzone mit einem Eintrittsschlitz 9 für den Schaft der Spannschraube 3 versehen zu werden.In this embodiment, it is also only necessary to provide this busbar part 1b in its end region in the region of the separation zone with an entry slot 9 for the shaft of the tensioning screw 3.
