Definitions

  • the invention relates to a hinge for forming a pivot connection between a frame on which electrical conductors and power supply elements are mounted, and at least one switching flap, which can accommodate switching means, e.g. Fuses or knife cartridges, whereby the switching flap can be pivoted by means of the hinge between a position in which the switching means are arranged and are coupled to the electrical conductors of the power supply elements fastened to the frame, and these are covered with the switching means by the switching flap, and a position , in which the switching flap is removed from the frame, and the switching means are located outside the power supply elements and the switching flap executes a flat curved path when pivoted.
  • switching means e.g. Fuses or knife cartridges
  • Such a hinge is known from DE-A-30 47 360.
  • Power supply devices e.g. two spring contacts connected to busbars to remove knife contacts from switching devices as load disconnectors for fuses are usually at given, standardized mutual intervals. So the distance for e.g. Knife cartridges normalized to 56.5 and 80 mm, while the length of the cartridge body, in the ends of which are the knives that are pressed between the spring contacts, have lengths of 54 and 75 mm, respectively. This means that there is a clearance between the end walls of the cartridge body and the spring contacts of 2.5 or 5 mm.
  • the hinge point comes to lie in the vicinity of the cartridge underneath and its spring contacts.
  • the strip that is taken up by the fuses arranged one above the other on the frame becomes wider and takes up more space.
  • the lowest hinge point of a row of cartridges also comes in front of the central connection terminals, which makes it difficult to connect.
  • the switching flap executes a flat curved path by means of a hinge whose hinge point is not arranged as far from the center of the knife cartridge as in DE-A-32 14 483. But also this hinge meets the problem of low clearance and this has been solved here by using different spring contacts that are chamfered on the inlet side of the knife cartridge.
  • the hinge has at least one rolling surface firmly connected to the frame and at least one rolling element firmly connected to the switching flap for the rolling surface, the rolling element consisting of at least one gear or a sector thereof, and the rolling surface consists of at least one toothed rack or ring gear, the rolling surface being located in a surface which is perpendicular to the pivoting surface of the switching flap outside the area between the power supply elements and which is turned towards the side of the frame on which the switching flap is located is located, the rolling element is located outside the switching flap near an edge of the switching flap, and is parallel to this edge perpendicular to the aforementioned swivel surface, the rolling surface and the rolling element are bent and such a position relative to the Weg take lobe or the frame that the switching flap is moved in a flat arc path between the positions in which the switching means are connected to or removed from the power supply members of the frame during the pivoting movement.
  • the switching flap is pivoted about a moving pivot, as a result of the rolling of the rolling element on the rolling surface.
  • This will make the Arch, along which the switching flap is pivoted, much flatter than when pivoting about a fixed hinge point and when pivoting by means of the hinge according to DE-A-30 47 360.
  • the cartridge can thus approach the spring contacts in a much flatter path and also after this much flatter track can be removed from the position between the spring contacts without chamfering the spring contacts.
  • the rolling surface can be placed much closer to the center of the flap than the fixed hinge point mentioned above.
  • the current is only interrupted at one point. Therefore, only one blowing chamber is necessary even with larger currents.
  • the rack can run parallel to the axis of the switching flap or form an angle with it. Due to the short hinge distance, it is also possible to form a separate solid part per phase in the above-mentioned normalized masses. This offers a number of advantages, e.g. in production and stockpiling, since a three-phase strip now consists of three identical parts. In the event of a fault in a phase part, it is sufficient to replace only the part and not the entire three-phase strip. These single-phase solid parts can also be used side by side for one or more single-pole cartridge holders.
  • the switching flap In order to be able to safely place or remove a knife cartridge or a connecting knife or the like in the switching flap, the switching flap should be able to be removed completely from the frame.
  • the hinge according to the invention can be removed for this purpose, for which purpose the switching flap and the frame are provided with guide means, so that the loose switching flap with the rolling element attached to it can be brought into the pivoting position in which the rolling element comes into contact with the rolling surface, and out there this pivot position can be performed in the effective position of the switching means with respect to the power supply elements.
  • the switching flap is preferably provided with lateral cams which extend transversely to the pivoting surface and which interact with guide grooves which are arranged in strips or side walls which are fixedly mounted on the frame, in surfaces which run parallel to the pivoting surface, through which cams and Grooves the switching flap can be guided into said swivel position, the rolling surface and the rolling element cooperating with one another, and the grooves mentioned in this swiveling position giving the cam of the switching flap freedom of movement for the swiveling of the switching part when the rolling element rolls over the rolling surface.
  • Each said groove preferably has a first part which leads to the rolling surface and cooperates with the cam in such a way that the switching flap can only be brought into the pivoted position in which the switching means are located outside the current supply elements or can be removed from them and in one
  • the outer end in the area of the rolling surface has a second part adjoining it, which extends essentially in the same direction as the rolling surface, in such a way that the cam can be moved by this connecting second groove part when the rolling element rolls over the rolling surface.
  • a switching flap 2 is shown in partial section in FIG.
  • a knife cartridge 1 is arranged with the knives 8 and 9 and a cartridge body 10.
  • the means necessary for holding the knife cartridge 1 in the switching flap 2 are not shown in this figure for reasons of clarity. For safety's sake, these means are designed such that the knife cartridge 1 can only be arranged in this position in the switching flap 2 or removed therefrom.

Description

Die Erfindung bezieht sich auf ein Scharnier zur Bildung einer Schwenkverbindung zwischen einem Gestell, auf welchem elektrische Leiter und Stromzufuhrorgane montiert sind, und mindestens einer Schaltklappe, welche Schaltmittel aufnehmen kann, wie z.B. Schmelzsicherungen oder Messerpatronen, wobei mittels des Scharnieres die Schaltklappe geschwenkt werden kann zwischen einer Stellung, in welcher die Schaltmittel angeordnet sind und gekoppelt sind mit den elektrischen Leitern der am Gestell befestigten Stromzufuhrorgane, und diese mit den Schaltmitteln durch die Schaltklappe bedeckt sind, und einer Stellung, in welcher die Schaltklappe vom Gestell entfernt ist, und die Schaltmittel ausserhalb der Stromzufuhrorgane liegen und die Schaltklappe beim Schwenken eine flache Bogenbahn ausführt.The invention relates to a hinge for forming a pivot connection between a frame on which electrical conductors and power supply elements are mounted, and at least one switching flap, which can accommodate switching means, e.g. Fuses or knife cartridges, whereby the switching flap can be pivoted by means of the hinge between a position in which the switching means are arranged and are coupled to the electrical conductors of the power supply elements fastened to the frame, and these are covered with the switching means by the switching flap, and a position , in which the switching flap is removed from the frame, and the switching means are located outside the power supply elements and the switching flap executes a flat curved path when pivoted.

Eine derartige Scharnier ist aus der DE-A- 30 47 360 bekannt.Such a hinge is known from DE-A-30 47 360.

Stromzufuhrorgane, wie z.B. zwei auf Stromschienen angeschlossene Federkontakte zum Ausnehmen von Messerkontakten von Schaltmitteln als Lasttrenner von Schmelzsicherungen stehen meistens in gegebenen genormten gegenseitigen Abständen. So ist der Abstand für z.B. Messerpatronen normalisiert auf 56,5 und 80 mm, während die Länge des Patronenkörpers, in dessen Enden sich die Messer befinden, die zwischen die Federkontakte gedrückt werden, Längen besitzen von 54 bzw. 75 mm. Das bedeutet, dass es ein Spiel zwischen den Endwänden des Patronenkörpers und den Federkontakten von 2,5 bzw. 5 mm gibt.Power supply devices, e.g. two spring contacts connected to busbars to remove knife contacts from switching devices as load disconnectors for fuses are usually at given, standardized mutual intervals. So the distance for e.g. Knife cartridges normalized to 56.5 and 80 mm, while the length of the cartridge body, in the ends of which are the knives that are pressed between the spring contacts, have lengths of 54 and 75 mm, respectively. This means that there is a clearance between the end walls of the cartridge body and the spring contacts of 2.5 or 5 mm.

Falls die Messerpatronen mit Hilfe eines losen Bedienungsgriffes nahezu parallel zwischen den Federkontakten angeordnet werden müssen, d.h. in einer Linie, die ungefähr senkrecht steht zu der Verbindungslinie zwischen den Federkontakten, besteht genügend Spiel um die Körper der Messerpatronen zwischen die Federkontakte anzuordnen und wieder zu entfernen. Mit einem losen Bedienungshandgriff ist jedoch die Bedienung unter Spannung, insbesondere unter Strombelastung diskutabel. Darum erhebt sich immer mehr die Frage nach sicher bedienbaren Messerkontakten und anderen Schmelzsicherungen und Schaltmitteln.If the knife cartridges have to be arranged almost parallel between the spring contacts using a loose control handle, i.e. in a line that is approximately perpendicular to the connecting line between the spring contacts, there is enough play to arrange and remove the bodies of the knife cartridges between the spring contacts. With a loose operating handle, however, operation under voltage, especially under current, is debatable. That is why the question of safe-to-use knife contacts and other fuses and switching devices is increasing.

Bei einer aus der deutschen Offenlegungsschrift DE-A- 32 14 483 bekannten Ausführung wird dies mit Hilfe einer Schaltklappe erreicht, in welcher die Schmelzsicherungen untergebracht sind und diese mit den Stromzufuhrorganen gegen Berührung abgeschirmt sind. Die Klappe ist an der Unterseite scharnierend mit dem Gestell verbunden, so dass die sich darin befindende Sicherungspatrone beim Drehen um den Scharnierpunkt, zwischen die Federkontakte angebracht werden kann bzw. aus der Stellung entfernt werden kann. Mit Rücksicht auf das geringe Spiel zwischen den Federkontakten und dem Körper der Messerpatrone muss der Scharnierpunkt auf dem Gestell jedoch fern von der Mitte der Schaltklappe angeordnet werden um zu verhindern, dass der Patronenkörper zwischen den Federkontakten klemmt oder dagegen stösst. Ein weit entfernter Scharnierpunkt hat jedoch eine Reihe von Nachteilen. Bei Mehrphasenvorrichtungen, wobei im allgemeinen die Patronen der Phasen in gegenseitiger Verlängerung übereinander angeordnet sind, kommt der Scharnierpunkt in die Nähe der darunter befindlichen Patrone und deren Federkontakte zu liegen. Dadurch wird der Streifen der durch die übereinander geordneten Sicherungen auf dem Gestell eingenommen wird, breiter und nimmt mehr Platz ein. Der unterste Scharnierpunkt einer Reihe von Patronen kommt ausserdem vor die zentralen Anschlussklemmen zu liegen, wodurch das Anschliessen erschwert wird.In a version known from German published patent application DE-A-32 14 483, this is achieved with the aid of a switching flap in which the fuses are accommodated and these are shielded against contact with the current supply elements. The flap is hinged to the frame on the underside, so that the fuse cartridge inside can be attached between the spring contacts or removed from the position when rotating around the hinge point. In view of the slight play between the spring contacts and the body of the knife cartridge, the hinge point on the frame must be located far from the center of the switching flap to prevent the cartridge body from jamming or pushing against the spring contacts. However, a distant hinge point has a number of disadvantages. In the case of multi-phase devices, the cartridges of the phases generally being arranged one above the other in an extension of one another, the hinge point comes to lie in the vicinity of the cartridge underneath and its spring contacts. As a result, the strip that is taken up by the fuses arranged one above the other on the frame becomes wider and takes up more space. The lowest hinge point of a row of cartridges also comes in front of the central connection terminals, which makes it difficult to connect.

Es sind zwar Lösungen bekannt, wobei die Patrone zuerst parallel aus einer Stellung zwischen den Federkontakten bewegt wird und darauf in die vollständige offene Stellung gelangt, siehe DE-A- 33 11 571 und DE-B- 10 76 775. Das führt jedoch zu einer komplizierten Konstruktion mit mehr Teilen als bei einem weit entfernten Schamierpunkt. Durch die parallele Bewegung der Messerpatronen von den Federkontakten kann ausserdem die Unterbrechung an zwei Stellen gleichzeitig auftreten. Für eine derartige Unterbrechung an zwei Stellen gleichzeitig sind bei grösseren Strömen auch zwei Blaskammern nötig.Although solutions are known, the cartridge is first moved in parallel from a position between the spring contacts and then reaches the fully open position, see DE-A-33 11 571 and DE-B-10 76 775. However, this leads to a complicated construction with more parts than at a distant hinge point. Due to the parallel movement of the knife cartridges from the spring contacts, the interruption can also occur at two points simultaneously. For such an interruption at two points at the same time, two blowing chambers are necessary for larger currents.

Bei dem Scharnier gemäss der obenerwähnten DE-A- 30 47 360 führt die Schaltklappe eine flache Bogenbahn aus mittels eines Scharnieres dessen Scharnierpunkt nicht so fern von der Mitte der Messerpatrone angeordnet ist wie in der DE-A- 32 14 483. Aber auch dieses Scharnier stösst auf das Problem des geringen Spieles und man hat das hier gelöst durch Verwendung von abweichenden, an der Eintrittseite der Messerpatrone abgeschrägten Federkontakten.In the hinge according to the above-mentioned DE-A-30 47 360, the switching flap executes a flat curved path by means of a hinge whose hinge point is not arranged as far from the center of the knife cartridge as in DE-A-32 14 483. But also this hinge meets the problem of low clearance and this has been solved here by using different spring contacts that are chamfered on the inlet side of the knife cartridge.

Die obigen Nachteile werden durch das erfindungsgemässe Scharnier vermieden, das dadurch gekennzeichnet ist, dass das Scharnier mindestens eine fest mit dem Gestell verbundene Rollfläche und mindestens ein fest mit der Schaltklappe verbundenes Rollorgan für die Rollfläche aufweist, wobei das Rollorgan aus mindestens einem Zahnrad oder einem Sektor davon, und die Rollfläche aus mindestens einer Zahnstange oder einem Zahnkranz besteht, wobei sich die Rollfläche in einer Fläche befindet, welche lotrecht zur Schwenkfläche der Schaltklappe ausserhalb des Bereiches zwischen den Stromzufuhrorganen steht und gekehrt ist nach der Seite des Gestelles, an welcher sich die Schaltklappe befindet, wobei das Rollorgan ausserhalb der Schaltklappe in der Nähe eines Randes der Schaltklappe gelegen ist, und parallel mit diesem Rand verlaufend lotrecht auf die erwähnte Schwenkfläche steht, wobei die Rollfläche und das Rollorgan so gebogen sind und eine derartige Stellung gegenüber der Schaltklappe bzw. dem Gestell einnehmen, dass bei der Schwenkbewegung die Schaltklappe in einer flachen Bogenbahn zwischen den Stellungen bewegt wird, in welchen die Schaltmittel mit den Stromzufuhrorganen des Gestelles verbunden bzw. von diesen entfernt sind.The above disadvantages are avoided by the hinge according to the invention, which is characterized in that the hinge has at least one rolling surface firmly connected to the frame and at least one rolling element firmly connected to the switching flap for the rolling surface, the rolling element consisting of at least one gear or a sector thereof, and the rolling surface consists of at least one toothed rack or ring gear, the rolling surface being located in a surface which is perpendicular to the pivoting surface of the switching flap outside the area between the power supply elements and which is turned towards the side of the frame on which the switching flap is located is located, the rolling element is located outside the switching flap near an edge of the switching flap, and is parallel to this edge perpendicular to the aforementioned swivel surface, the rolling surface and the rolling element are bent and such a position relative to the Schaltk take lobe or the frame that the switching flap is moved in a flat arc path between the positions in which the switching means are connected to or removed from the power supply members of the frame during the pivoting movement.

Bei dem Scharnier nach der Erfindung wird die Schaltklappe um einen sich bewegenden Drehpunkt geschwenkt, und zwar als Folge des Abwälzen des Rollorganes auf der Rollfläche. Dadurch wird der Bogen, entlang welchem die Schaltklappe geschwenkt wird, viel flacher als beim Schwenken um einen festen Scharnierpunkt und beim Schwenken mittels des Scharnieres gemäss der DE-A- 30 47 360. Die Patrone kann sich den Federkontakten so in einer viel flacheren Bahn nähern und ebenfalls nach dieser viel flacheren Bahn aus der Position zwischen den Federkontakten entfernt werden ohne Abschrägung der Federkontakte. Die Rollfläche kann viel näher bei der Mitte der Schaltklappe angebracht werden als beim obengenannten festen Scharnierpunkt. Ausserdem wird der Strom dabei nur an einer Stelle unterbrochen. Daher ist auch bei grösseren Strömen nur eine Blaskammer nötig.In the hinge according to the invention, the switching flap is pivoted about a moving pivot, as a result of the rolling of the rolling element on the rolling surface. This will make the Arch, along which the switching flap is pivoted, much flatter than when pivoting about a fixed hinge point and when pivoting by means of the hinge according to DE-A-30 47 360. The cartridge can thus approach the spring contacts in a much flatter path and also after this much flatter track can be removed from the position between the spring contacts without chamfering the spring contacts. The rolling surface can be placed much closer to the center of the flap than the fixed hinge point mentioned above. In addition, the current is only interrupted at one point. Therefore, only one blowing chamber is necessary even with larger currents.

Die Zahnstange kann parallel mit der Achse der Schaltklappe verlaufen oder damit einen Winkel bilden. Durch den kurzen Scharnierabstand ist es ausserdem möglich in den obigen genannten normalisierten Massen pro Phase einen separaten festen Teil zu bilden. Das bietet eine Reihe von Vorteilen, z.B. bei der Produktion und Vorrathaltung, da ein dreiphasiger Streifen jetzt aus drei identischen Teilen besteht. Bei einer Störung in einem Phasenteil genügt es nur den Teil und nicht den ganzen dreiphasigen Streifen auszuwechseln. Diese einphasigen festen Teile sind ausserdem für einen oder mehrere einpolige Patronenhalter nebeneinander verwendbar.The rack can run parallel to the axis of the switching flap or form an angle with it. Due to the short hinge distance, it is also possible to form a separate solid part per phase in the above-mentioned normalized masses. This offers a number of advantages, e.g. in production and stockpiling, since a three-phase strip now consists of three identical parts. In the event of a fault in a phase part, it is sufficient to replace only the part and not the entire three-phase strip. These single-phase solid parts can also be used side by side for one or more single-pole cartridge holders.

Bei bestimmten Abnehmern wird verlangt, dass bei Sicherungsstreifen alle drei Patronen gleichzeitig eingeschaltet und ausgeschaltet werden. Das ist mit dem Scharnier nach der Erfindung ohne Schwierigkeiten möglich, mit dem Vorteil, dass auch hier die zentralen Anschlusspunkte an der Unterseite gut erreichbar bleiben.Certain customers require that all three cartridges on security strips be switched on and off at the same time. This is possible with no difficulty with the hinge according to the invention, with the advantage that the central connection points on the underside also remain easily accessible here.

Um ganz sicher eine Messerpatrone oder ein Verbindungsmesser oder dergleichen in der Schaltklappe anordnen oder daraus entfernen zu können, soll die Schaltklappe ganz aus dem Gestell entnommen werden können. Das erfindungsgemässe Scharnier ist zu diesem Zweck abnehmbar, wozu die Schaltklappe und das Gestell mit Führungsmitteln versehen sind, damit die lose Schaltklappe mit dem daran befestigten Rollorgan in die Schwenkstellung gebracht werden kann, in welcher das Rollorgan mit der Rollfläche in Kontakt kommt, und darauf aus dieser Schwenkstellung in die wirksame Stellung der Schaltmittel bezüglich der Stromzufuhrorganen geführt werden kann.In order to be able to safely place or remove a knife cartridge or a connecting knife or the like in the switching flap, the switching flap should be able to be removed completely from the frame. The hinge according to the invention can be removed for this purpose, for which purpose the switching flap and the frame are provided with guide means, so that the loose switching flap with the rolling element attached to it can be brought into the pivoting position in which the rolling element comes into contact with the rolling surface, and out there this pivot position can be performed in the effective position of the switching means with respect to the power supply elements.

Vorzugsweise ist die Schaltklappe zu diesem Zweck mit seitlichen Nocken versehen, die sich quer zur Schwenkfläche erstrecken und die zusammenwirken mit Führungsnuten, die in fest auf dem Gestell montierten Streifen oder Seitenwänden angeordnet sind, in Flächen welche parallel zu der Schwenkfläche verlaufen, durch welche Nocken und Nuten die Schaltklappe in die genannte Schwenkstellung geführt werden kann, wobei die Rollfläche und das Rollorgan miteinander zusammenwirken und wobei die erwähnten Nuten in dieser Schwenkstellung den Nocken der Schaltklappe eine Bewegungsfreiheit-für das Schwenken des Schaltteiles beim Rollen des Rollorganes über die Rollfläche geben.For this purpose, the switching flap is preferably provided with lateral cams which extend transversely to the pivoting surface and which interact with guide grooves which are arranged in strips or side walls which are fixedly mounted on the frame, in surfaces which run parallel to the pivoting surface, through which cams and Grooves the switching flap can be guided into said swivel position, the rolling surface and the rolling element cooperating with one another, and the grooves mentioned in this swiveling position giving the cam of the switching flap freedom of movement for the swiveling of the switching part when the rolling element rolls over the rolling surface.

Jede genannte Nut hat dabei vorzugsweise einen ersten Teil, der zur Rollfläche führt und derart mit dem Nocken zusammenwirkt, dass die Schaltklappe ausschliesslich in die Schwenkstellung gebracht werden kann, in welcher die Schaltmittel ausserhalb der Stromzufuhrorgane liegen bzw. von diesen entfernt werden können und in einem Aussenende im Bereich der Rollfläche einen daran anschliessenden zweiten Teil aufweist, der sich im wesentlichen in derselben Richtung erstreckt wie die Rollfläche, derart, dass der Nocken durch diesen anschliessenden zweiten Nutteil beim Rollen des Rollorganes über die Rollfläche bewegt werden kann.Each said groove preferably has a first part which leads to the rolling surface and cooperates with the cam in such a way that the switching flap can only be brought into the pivoted position in which the switching means are located outside the current supply elements or can be removed from them and in one The outer end in the area of the rolling surface has a second part adjoining it, which extends essentially in the same direction as the rolling surface, in such a way that the cam can be moved by this connecting second groove part when the rolling element rolls over the rolling surface.

  • Figures 4 to 8 show successively positions which are assumed when the switching flap is guided into the pivoting position and the pivoting into the closed position according to FIGS. 2 and 3.

In der Figur 1 ist eine Schaltklappe 2 im Teilschnitt dargestellt. In dieser Schaltklappe 2 ist eine Messerpatrone 1 angeordnet mit den Messern 8 und 9 und einem Patronenkörper 10. Die zum Festhalten der Messerpatrone 1 in der Schaltklappe 2 notwendigen Mittel sind in dieser Figur aus Anschaulichkeitsgründen nicht gezeichnet. Diese Mittel sind sicherheitshalber so ausgeführt, dass die Messerpatrone 1 nur in dieser Stellung in der Schaltklappe 2 angeordnet oder daraus entfernt werden kann.A switching flap 2 is shown in partial section in FIG. In this switching flap 2 a knife cartridge 1 is arranged with the knives 8 and 9 and a cartridge body 10. The means necessary for holding the knife cartridge 1 in the switching flap 2 are not shown in this figure for reasons of clarity. For safety's sake, these means are designed such that the knife cartridge 1 can only be arranged in this position in the switching flap 2 or removed therefrom.

Links von der Schaltklappe 2 und der Messerpatrone 1 ist ein Teil des Gestelles 11 mit Federkontakten 12 und 13 dargestellt. Das Gestell 11 ist mit Seitenwänden oder Seitenstreifen 14 versehen, von denen in Figur 1 einer und zwar nur teilweise dargestellt ist. Diese Seitenwände sind mit Nuten 4 versehen, die in der Figur 1 von den Seitenwände 14 zuerst schräg nach links nach unten verlaufen und darauf einen anschliessenden Teil 7 enthalten, der horizontal nach links läuft und hier etwas breiter ist als der Nutteil 4. Der Seitenwände 14 mit Nuten 4 und 7 befinden sich an beiden Seiten des Federkontaktes 13. Die Seitenwände 14 müssen sich nicht wie aus Figur 2 hervorgeht über die ganze Länge der Messerpatrone 1 ausstrecken. Es genügt nur, wenn örtlich Streifen oder Wände vorhanden sind, in welchen die Nuten 4 und 7 untergebracht werden können.To the left of the switching flap 2 and the knife cartridge 1, part of the frame 11 with spring contacts 12 and 13 is shown. The frame 11 is provided with side walls or side strips 14, of which one is shown only partially in FIG. 1. These side walls are provided with grooves 4, which in FIG. 1 initially run obliquely downward from the side walls 14 and then contain a connecting part 7, which runs horizontally to the left and here is somewhat wider than the groove part 4. The side walls 14 with grooves 4 and 7 are located on both sides of the spring contact 13. The side walls 14 do not have to extend over the entire length of the knife cartridge 1 as shown in FIG. It is only sufficient if there are local strips or walls in which the grooves 4 and 7 can be accommodated.

Die Schaltklappe 2 ist an einem Verlängerungsstück an der linken unteren Seite mit nach aussen vorstehenden Nocken 3 versehen, und zwar an beiden Seiten der Schaltklappe 2, wie in Figur 1 dargestellt ist. Die Nocken 3 stehen, wie Figur 2 zeigt, an beiden Seiten etwas aus den Verlängerungsstücken der Schaltklappe hervor. Nach der Figur 2 ist die Schaltklappe an der Stelle der Seitenwand 14 etwas schmäler.The switching flap 2 is provided on an extension piece on the lower left side with cams 3 projecting outwards, on both sides of the switching flap 2, as shown in FIG. 1 represents is. As shown in FIG. 2, the cams 3 protrude somewhat from the extension pieces of the switching flap on both sides. According to FIG. 2, the switching flap is somewhat narrower at the location of the side wall 14.

Weiter zeigt Figur 1 eine Verzahnung mit einer Zahnstange 6 und eine damit zusammenwirkende Verzahnung eines Zahnradsegmentes 5. Die Zahnstange 6 ist in einem fest mit dem Gestell 11 verbundenen Teil ausgebildet, z.B. in dem oberen Ende eines Streifens, der an der Innenseite oder Aussenseite an der Seitenwand 14 befestigt ist oder mit dieser ein Ganzes bildet. Das Zahnsegment 5 ist fest mit der Schaltklappe 2 verbunden und bildet mit dieser Kappe ein Ganzes.1 shows a toothing with a toothed rack 6 and a toothing of a gearwheel segment 5 interacting therewith. The toothed rack 6 is formed in a part which is firmly connected to the frame 11, e.g. in the upper end of a strip which is attached to the inside or outside of the side wall 14 or forms a whole with it. The toothed segment 5 is firmly connected to the switching flap 2 and forms a whole with this cap.

Wie Figur 3 zeigt, können die Seitenwände 14 auch örtlich etwas näher zueinander angeordnet sein. In diesem Fall stehen die Nocken 3 nach innen von Verlängerungsstücken der Schaltklappe vor. Bei 5 und 6 liegen die Verzahnungen einander gegenüber, hier also mehr an der Aussenseite.As FIG. 3 shows, the side walls 14 can also be arranged somewhat closer to one another locally. In this case, the cams 3 protrude inward from extension pieces of the switching flap. At 5 and 6 the teeth are opposite each other, so here on the outside.

Figur 1 zeigt die Stellung der Schaltklappe 2, in welcher die Nocken 3 durch die Nuten 4 links nach unten geschoben sind, bis einer der Zähne des Zahnsegmentes 5 in den Raum zwischen den Zähnen von der Zahnstange 6 eingreift. Die Nocken und Nuten sind so konstruiert und dimensioniert, dass nicht durch teilweises Einführen der Kappe 2 in Gestell 11 die Schaltmittel mit den Stromzufuhrorganen verbunden weden können, d.h., dass die . Schaltklappe gekantelt werden kann.Figure 1 shows the position of the switching flap 2, in which the cams 3 are pushed down through the grooves 4 on the left until one of the teeth of the toothed segment 5 engages in the space between the teeth of the rack 6. The cams and grooves are constructed and dimensioned such that the switching means cannot be connected to the power supply elements by partially inserting the cap 2 into the frame 11, i.e. that the. Switch flap can be tilted.

In der in Figur 1 dargestellten Stellung der Schaltklappe 2 kann dieser z.B. zum Auswechseln einer Messerpatrone 10 ganz aus dem Gestell 11 genommen werden, oder es wird die Schaltklappe 2 wieder in Gestell 11 angeordnet. Um die Messerpatrone 10 mit den Federkontakten 12 und 13 zu verbinden, wird die Schaltklappe 2 mit Hilfe eines Handgriffes 15 nach links oben gedrückt. Dann verhindern die Nocken 3, dass das linke untere Ende der Schaltklappe 2 mit dem Zahnradsegment 5 nach oben bewegt wird, weil jeder Nocken 3 nun in den zugehörigen breiten Nutenteil 7 in einer Richtung gegen die Zeiger eines Uhrwerkes drehen wird. Die Länge des Nockens 3 in den gebogenen Aussenenden ist so dimensioniert, dass der Nocken innerhalb der Nut 7 rollen kann und gleichzeitig nach links bewegt wird, jedoch erst sobald der Nocken die unterste Stellung erreicht hat, als Folge wovon das Zahnradsegment 5 auf die Zahnstange 6 gedrückt gehalten wird. Bei einem Drücken der Schaltklappe 2 nach links oben wird daher das Zahnradsegment 5 auf der Zahnstange 6 abgerollt. Die Folge davon ist, dass die Schaltklappe 2 in einer abgeflachten bogenförmigen Bahn nach links oben geschwenkt wird. Mit Strichpunktlinien 16, 17 sind dabei die Bewegungslinien angegeben, die die Aussenenden des Körpers 10 der Patrone 1 durchlaufen. Wie ersichtlich ist, bleiben diese Aussenenden innerhalb des Bereiches zwischen den Federkontakten 12 und 13.In the position of the switching flap 2 shown in FIG. 1, this can e.g. to replace a knife cartridge 10 can be taken completely from the frame 11, or the switching flap 2 is arranged again in the frame 11. In order to connect the knife cartridge 10 to the spring contacts 12 and 13, the switching flap 2 is pressed to the top left using a handle 15. Then the cams 3 prevent the lower left end of the switching flap 2 with the gear segment 5 from being moved upward, because each cam 3 will now rotate in the associated wide groove part 7 in one direction against the hands of a clockwork. The length of the cam 3 in the curved outer ends is dimensioned such that the cam can roll within the groove 7 and at the same time is moved to the left, but only as soon as the cam has reached the lowest position, as a result of which the gear segment 5 on the rack 6 is held down. When the switching flap 2 is pushed to the top left, the gear segment 5 is therefore rolled on the rack 6. The result of this is that the switching flap 2 is pivoted to the top left in a flattened arcuate path. Dashed lines 16, 17 indicate the lines of movement which run through the outer ends of the body 10 of the cartridge 1. As can be seen, these outer ends remain within the area between the spring contacts 12 and 13.

Mit gleichen Strichpunktlinien ist die Patrone 1 mit den Messern 8 und 9 wiedergegeben, wenn sich diese zwischen den Federkontakten 12 und 13 befindet.The cartridge 1 with the knives 8 and 9 is shown with the same broken lines when it is between the spring contacts 12 and 13.

Es versteht sich von selbst, dass der durchgelaufene Bogen viel flacher ist als beim Drehen der Schaltklappe 2 um ein festes Scharnier an der Stelle von z.B. des Nockens 3 oder auch der Zahnstange 6. Wenn als Drehpunkt z.B. ein Punkt gewählt wird, welcher sich an der Stelle des Punktes 16 links in der Nähe des zweiten Zahnes der Zahnstange 6 von rechts befindet, dann wird die linke obere Ecke des Körpers 10 der Ptrone nicht unter den obersten Federkontakt 12 durchgehen können, sondern wird gegen ihn stossen. Mit der strichpunktierten Linie 19 ist die Bahn angegeben, welche die linke obere Ecke des Körpers 10 der Patrone 1 dann durchlaufen soll. Durch Verwendung des Zahnsegmentes 5 und der Zahnstange 6 wird die linke obere Ecke des Körpers eine viel flacher gebogene Bahn durchlaufen und unter dem Federkontakt 12 bleiben. Auch wird das linke obere Ende des Patronenkörpers 10 nicht die obere Seite des Federkontaktes 13 berühren.It goes without saying that the sheet that has passed through is much flatter than when the switching flap 2 is rotated around a fixed hinge in the place of e.g. of the cam 3 or the rack 6. If the pivot point is e.g. If a point is chosen which is located at the point 16 on the left near the second tooth of the rack 6 from the right, then the upper left corner of the body 10 of the cartridge will not be able to pass under the uppermost spring contact 12, but instead will bump him. The dash-dotted line 19 indicates the path which the upper left corner of the body 10 of the cartridge 1 should then pass through. By using the toothed segment 5 and the toothed rack 6, the upper left corner of the body passes through a much flatter curved path and remains under the spring contact 12. Also, the upper left end of the cartridge body 10 will not touch the upper side of the spring contact 13.

Die Figuren 4 bis 8 zeigen noch einmal hintereinander folgend alle Stellungen, welche bei dem nach innen Schwenken der Schaltklappe 2 mit darin angebrachter Messerpatrone 1 durchlaufen werden.FIGS. 4 to 8 show once again in succession all the positions which are passed through when the switching flap 2 is pivoted inward with the knife cartridge 1 fitted therein.

Der Nocken 3 hat hier eine etwas abweichende Ausführungsform und besteht aus einem tunden Stift, der sich durch Nuten 20 in der linken unteren Seitenwand der Schaltklappe 2 erstreckt und dabei einigen Spielraum hat. Dieser Nocken 3 befindet sich in der Stellung nach der Figur 3 am Eingang der Nut 4. Darauf wird die Klappe 2 nach links unten gedrückt, siehe die Figur 5. In der Figur 6 ist der rechte Zahn in Berührung mit der Zahnstange 6 gekommen, und befindet sich der Nocken 3 and der Stelle, wo der Nutteil 4 in den horizontalen Nutteil 7 übergeht. Wenn darauf in der Folge die Schaltklappe 2 nach links oben geschwenkt wird (siehe Figur 7), läuft das Zahnradsegment 5 über die Zahnstange 6, während der Nocken 3 durch den Nutteil 7 nach links bewegt wird. Bei dem Durchlaufen dieser Bahn gelangt der Messerkontakt 9 in Berührung mit dem in Figur 1 dargestellten Federkontakt 13. Es kommt jedoch noch keine elektrische Verbindung zustande. Diese erfolgt erst bei dem Nähern in die Endstellung.The cam 3 here has a somewhat different embodiment and consists of a long pin which extends through grooves 20 in the lower left side wall of the switching flap 2 and has some scope. This cam 3 is in the position according to FIG. 3 at the entrance of the groove 4. The flap 2 is then pressed to the bottom left, see FIG. 5. In FIG. 6 the right tooth has come into contact with the rack 6, and there is the cam 3 at the point where the groove part 4 merges into the horizontal groove part 7. If the switching flap 2 is subsequently pivoted upward to the left (see FIG. 7), the gear segment 5 runs over the toothed rack 6, while the cam 3 is moved to the left through the groove part 7. When passing through this path, the knife contact 9 comes into contact with the spring contact 13 shown in FIG. 1. However, no electrical connection is yet established. This takes place only when approaching the end position.

In Figur 8 ist diese Endstellung dargestellt, in welcher die Schaltklappe vertikal steht, und die Patrone sich zwischen den Federkontakten befindet. In Figur 1 ist diese Stellung dargestellt mit Strichpunktlinien. Wenn die Schaltklappe wieder zurückgezogen wird, wird der Strom ausschliesslich durch den Messerkontakt 8 und den Federkontakt 12 unterbrochen.This end position is shown in FIG. 8, in which the switching flap is vertical and the cartridge is located between the spring contacts. In Figure 1 this position is shown with dashed lines. When the switching flap is withdrawn again, the current is interrupted exclusively by the knife contact 8 and the spring contact 12.

Es versteht sich von selbst, dass die Erfindung nicht auf die in den Figuren dargestellten Ausführungsformen begrenzt ist, die oben beschrieben wurden. Eine Kappe kann z.B. auch mehrere, z.B. drei Patronen 1 nebeneinander enthalten, die beim Schwenken der Klappe gleichzeitig zwischen zugehörigen Federkontakten 12 und 13 angeordnet werden. Der Zahnstangeteil 6 braucht nicht horizontal zu verlaufen, wie in den Figuren dargestellt ist. Ebensowenig braucht der Zahnradsegment 5 die in den Figuren dargestellte Stellung einzunehmen. Die Zahnstange kann z.B. auch vertikal verlaufen, während das Zahnradsegment 5 vom unteren Ende der Schaltklappe 2 nach links gerichtet ist.It goes without saying that the invention is not limited to the embodiments shown in the figures, which were described above. A cap can also contain, for example, several, for example three, cartridges 1 next to one another, which are arranged simultaneously between associated spring contacts 12 and 13 when the flap is pivoted. The rack part 6 does not need to run horizontally, as shown in the figures. The gear segment 5 does not need to assume the position shown in the figures. The rack can, for example, also run vertically, while the gear segment 5 is directed from the lower end of the switching flap 2 to the left.

Im vorangehenden wird von einem Zahnradsegment und einer Zahnstange gesprochen. Diese können jedoch auch bestehen aus einer einfachen Verzahnung, wie z.B. in den Figuren dargestellt ist oder anderen Reibungsrollteilen. Der Raum für diese miteinander zusammenwirkenden Verzahnungen wird begrenzt durch den Bogen, welcher durch den Körper 10 der Patronen durchlaufen wird, unter Berücksichtigung des Spielraumes zwischen den Federkontakten 12 und 13. Auch können andere Schaltmittel als Messerpatronen oder andere Schmelzsicherungen verwendet werden, wie z.B. Verbindungsmesser oder Trenner und dergleichen. Das Wesentliche der obigen Erfindung ist, dass sie eine spezielle scharnierende Ausschaltbewegung in einem begrenzten Raum gewährt.The foregoing speaks of a gear segment and a rack. However, these can also consist of a simple toothing, e.g. is shown in the figures or other friction rolling parts. The space for these mutually interacting toothings is limited by the arc which is passed through the body 10 of the cartridges, taking into account the clearance between the spring contacts 12 and 13. Switching means other than knife cartridges or other fuses, such as e.g. Connecting knife or disconnector and the like. The essence of the above invention is that it provides a special hinge-off movement in a limited space.
