Description

Die Erfindung betrifft eine Klemme zum Anklemmen von elektrischen Leitungen, mit einem offenen oder geschlossenen Rahmen, der einen U-förmigen ersten Abschnitt und einen die Schenkelenden miteinander verbindenden bzw. überbrückenden zweiten Abschnitt mit einer Gewindebohrung aufweist, und mit einer Klemmschraube, die in die Gewindebohrung einschraubbar ist,The invention relates to a clamp for clamping electrical lines, with an open or closed frame, which has a U-shaped first section and a second section connecting or bridging the leg ends with a threaded bore, and with a clamping screw, which in the threaded bore can be screwed in,

Derartige Klemmen dienen in der Hauptsache als Anschlußklemmen für elektrische Leiter bei Leitungsschutzschaltern, Fehlerstromschutzschaltern, Schützen und dergleichen. Die Leitungsdrähte werden zwischen dem freien Ende des Schraubenschaftes und dem Grund des U-förmigen Rahmens verklemmt, wobei die Leitungen lediglich in einer Richtung angeschlossen werden können.Such terminals are mainly used as terminals for electrical conductors in circuit breakers, residual current circuit breakers, contactors and the like. The lead wires are clamped between the free end of the screw shaft and the base of the U-shaped frame, and the leads can only be connected in one direction.

Es sind ferner Klemmen dieser Art bekanntgeworden, bei denen zusätzlich ein U-förmiger Druckbügel vorgesehen ist. Dessen einer Schenkel ist gabelförmig ausgebildet undLumgreift den Schraubenschaft unmittelbar unterhalb desSchraubenkopfes, wogegen der andere Schenkel in die Klemmöffnung eingreift und dabei das freie Ende des Schraubenschaftes überdeckt, so daß die elektrische Leitung zwischen der Außenfläche des anderen Schenkels und der Innenfläche des U-förmigen Rahmens festgeklemmt werden kann. Dabei besteht die Möglichkeit, den Druckbügel zweistückig auszubilden; der eine Teil ist L-förmig und zur Bildung des anderen, das freie Ende der Schraube überdeckenden Schenkels ist in dem Druckbügel eine schlitzartige Ausnehmung eingebracht, durch die ein weiteres Teil zur Bildung des anderen Schenkels durchsteckbar ist. Dieses weitere Teil kann beispielsweise einen Fortsatz aufweisen, so daß eine weitere Anschlußmöglichkeit gegeben ist. Anstatt den Rahmen U-förmig zu machen, besteht natürlich auch die Möglichkeit, den Rahmen geschlossen auszubilden, derart, daß die lose eingesetzte Mutter bei der Klemme der eingangs genannten Art einstückig mit dem Rahmen verbunden ist, so daß ein geschlossener, angenähert länglicher Ring gebildet ist, der an der dem Grund gegenüberliegenden Seite mit einer Bohrung mit Innengewinde zur Aufnahme der Klemmschraube versehen ist, was im Endeffekt der Mutter entspricht.Clamps of this type have also become known, in which a U-shaped pressure bracket is additionally provided. Its leg is fork-shaped and grips the Screw shaft immediately below the screw head, whereas the other leg engages in the clamping opening and thereby covers the free end of the screw shaft, so that the electrical cable can be clamped between the outer surface of the other leg and the inner surface of the U-shaped frame. It is possible to design the pressure bracket in two pieces; one part is L-shaped and to form the other, the free end of the screw covering leg is made in the pressure bracket, a slot-like recess through which another part can be pushed through to form the other leg. This further part can, for example, have an extension, so that there is a further connection possibility. Instead of making the frame U-shaped, there is of course also the possibility of forming the frame closed, such that the loosely inserted nut is integrally connected to the frame at the clamp of the type mentioned at the beginning, so that a closed, approximately elongated ring is formed is, which is provided on the opposite side of the bottom with a bore with an internal thread for receiving the clamping screw, which in the end corresponds to the nut.

An diesen Klemmen konnten ein oder mehrere Leiterdrähte angeschlossen werden und zwar immer nur in einer Richtung. Selbstverständlich ist auch ein Verklemmen von Leitungen zwischen dem Schraubenkopf bzw. dem einen Schenkel des Druckbügels und den Schenkelendkanten des Rahmens möglich.One or more conductor wires could be connected to these terminals and only ever in one direction. Of course, jamming of lines between the screw head or the one leg of the pressure bracket and the leg end edges of the frame is also possible.

Aufgabe der Erfindung ist es, eine Klemme der eingangs genannten Art zu schaffen, die universeller eingesetzt werden kann.The object of the invention is to provide a clamp of the type mentioned that can be used more universally.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß in den Schenkeln ausgehend von den Ausnehmungen je ein Schlitz vorgesehen ist, der bis in den Bereich des Grundes des U-förmigen Rahmens reicht.This object is achieved in that a slot is provided in the legs starting from the recesses, which extends into the area of the bottom of the U-shaped frame.

Wenn die Klemme zusätzlich einen U-förmigen Druckbügel aufweist, dessen einer Schenkel gabelartig ausgebildet ist und den Schraubenschaft im Bereich des Schraubenkopfes umfaßt und dessen anderer Schenkel das freie Ende der Klemmschraube im Inneren des Rahmens überdeckt, dann besteht eine weitere vorteilhafte Ausgestaltung der Erfindung darin, daß der andere Schenkel beidseitig Nasen besitzt, die in die Schlitze zur Führung des Druckbügels eingreifen.If the clamp additionally has a U-shaped pressure bracket, one leg of which is fork-shaped and comprises the screw shaft in the region of the screw head and the other leg of which covers the free end of the clamping screw in the interior of the frame, then a further advantageous embodiment of the invention consists in that the other leg has lugs on both sides, which engage in the slots for guiding the pressure bracket.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind den weiteren Unteransprüchen zu entnehmen.Further advantageous embodiments of the invention can be found in the further subclaims.

Die Vorteile, die mit der erfindungsgemäßen Klemme erzielt werden, bestehen zum einen darin, daß durch das Vorsehen eines Schlitzes ein Anschluß auch quer zu der Richtung des Rahmens erfolgen kann, derart, daß Anschlußdrähte durch die seitlichen Schlitze, also die Schlitze, die sich in den Schenkeln des Rahmens befinden, hindurchgesteckt und mittels der Schraube oder dem,anderen Schenkel des U-förmigen Druckbügels festgeklemmt werden können. Die Anschlußrichtung ist dadurch geändert. Ein weiterer, besonders wesentlicher Vorteil dieser Ausgestaltung besteht darin, daß der Druckbügel mit seinen beiden Fortsätzen in den Schlitzen geführt wird und dadurch in jedem Falle unverlierbar und hin und herbeweglich an der Klemme bzw. an dem Rahmen gehaltert ist. Darüberhinaus können aufgrund der halbkreisförmigen Ausgestaltung des U-förmigen Abschnittes eine größere Anzahl von Drähten kleinen Querschnittes gleichzeitig festgeklemmt werden. Dadurch, daß die Schlitze in den Schenkeln bis hin zu dem Grund des U-förmigen Abschnittes hingeführt sind, können auch Drähte angeklemmt werden, deren Querschnitt 0,75 mm2 beträgt.The advantages that can be achieved with the clamp according to the invention are, on the one hand, that by providing a slot, a connection can also be made transversely to the direction of the frame, in such a way that connecting wires through the side slots, that is, the slots that are in the legs of the frame are inserted and can be clamped by means of the screw or the other leg of the U-shaped pressure bracket. The connection direction is changed. Another, particularly significant advantage of this embodiment is that the pressure bracket is guided with its two extensions in the slots and is thereby held captive and movable back and forth on the clamp or on the frame. In addition, due to the semicircular design of the U-shaped section, a larger number of wires of small cross-section can be clamped at the same time. Because the slots in the legs extend to the base of the U-shaped section, wires can also be clamped, the cross section of which is 0.75 mm 2.

Anhand der Zeichnung, in der ein Ausführungsbeispiel dargestellt ist, sollen die Erfindung sowie weitere vorteilhafte Ausgestaltungen und Verbesserungen der Erfindung näher erläutert und beschrieben werden.The invention and further advantageous refinements and improvements of the invention are to be explained and described in more detail with reference to the drawing, in which an exemplary embodiment is shown.

Eine erfindungsgemäße Klemme 10 besitzt einen Rahmen mit einem U-förmigen ersten Abschnitt 12 mit zwei Schenkeln 14 und 16, die durch einen halbkreisförmigen Bereich 18 (Grund des U-förmigen Abschnittes) in Verbindung stehen. Beide Schenkel besitzen rechteckige Ausnehmungen 20 und 22 im Bereich des Schenkelendes, an die sich Schlitze 24 und 26 anschliessen, welche in den halbkreisförmigen Bereich - ausgehend von der Ausnehmung 20 bzw. 22 - hineinragen. Zwischen den Schlitzen 24 und 26 ist in dem halbkreisförmige Bereich ein ungeschlitzter Bereich 28 vorgesehen. Die Breite der Ausnehmung - parallel zu der freien Kante 30 gemessen, ist größer als die Breite des Schlitzes 24 bzw. 26.A clamp 10 according to the invention has a frame with a U-shaped first section 12 with two legs 14 and 16 which are connected by a semicircular region 18 (bottom of the U-shaped section). Both legs have rectangular recesses 20 and 22 in the region of the leg end, to which slots 24 and 26 adjoin, which protrude into the semicircular region - starting from the recess 20 and 22, respectively. An unslit region 28 is provided between the slots 24 and 26 in the semicircular region. The width of the recess — measured parallel to the free edge 30, is larger than the width of the slot 24 or 26.

Zwischen den beiden Schenkeln 14 und 16 ist eine Mutter 32 eingesetzt, die beidseitig Fortsätzen 34 besitzt (nur der::'Fortsatz rethts ist in der Zeichnung Figur 1 zu sehen), die in die Ausnehmungen 20 und 22 hineingreifen, wodurch die Mutter im ersten Abschnitt unverlierbar gehaltert ist; die Mutter verbindet die Schenkel und wird auch als zweiter Abschnitt bezeichnet.Between the two legs 14 and 16, a nut 32 is inserted, which has extensions 34 on both sides (only the :: 'extension rethts can be seen in the drawing Figure 1), which engage in the recesses 20 and 22, whereby the mother in the first Section is held captive; the mother connects the legs and is also referred to as the second section.

Die Mutter 32 besitzt eine Bohrung 35 mit Innengewinde, in die der mit einem Außengewinde 36 versehene Schaft 38 einer Klemmschraube 40 eingeschraubt ist. Die Klemmschraube 40 ist eine Kopf-Schraube mit einem Kopf 42.The nut 32 has a bore 35 with an internal thread, into which the shaft 38 of a clamping screw 40, which is provided with an external thread 36, is screwed. The clamping screw 40 is a head screw with a head 42.

Die Klemme besitzt ferner einen Druckbügel 50, der U-förmig mit einem ersten Schenkel 52 und mit einem zweiten Schenkel 54 ausgebildet ist, wobei der erste Schenkel 52 gabelförmig mit einer schlitzartigen Ausnehmung 56 ausgebildet ist, in die der Schraubenschaft unmittelbar unter dem Schraubenkopf 42 eingreift. Durch eine plastische Verformung der Gabelzinken des Schenkels 52 kann der Druckbügel mit dem Schenkel 52 bzw. über diesen unverlierbar mit der Schraube 40 verbunden werden. Der andere Schenkel 54 greift in das Innere des Rahmens ein und überdeckt dabei die freie Stirnfläche des Schraubenschaftes 38. Beidseitig an dem Schenkel 54 sind Nasen 58 und 60 angebracht, die in die Schlitze 24 bzw. 26 eingreifen und zur Führung des Druckbügels 50 beitragen. Das freie Ende des zweiten Schenkels 54 ist nach oben hin, also zum anderen Schenkel 52 hin geringfügig abgebogen, siehe Bezugsziffer 62.The clamp also has a pressure bracket 50 which is U-shaped with a first leg 52 and with a second leg 54, the first leg 52 being fork-shaped with a slot-like recess 56 into which the screw shaft engages directly under the screw head 42 . By means of a plastic deformation of the fork tines of the leg 52, the pressure bracket can be connected to the leg 52 or, via this, captively to the screw 40. The other leg 54 engages in the interior of the frame and thereby covers the free end face of the screw shaft 38. Lugs 58 and 60 are attached on both sides of the leg 54, which in the Engage slots 24 and 26 and contribute to guiding the pressure bracket 50. The free end of the second leg 54 is bent slightly upward, that is to say towards the other leg 52, see reference number 62.

Die Kanten 30 der beiden Schenkel 14 und 16 , die die Mitte überragen, besitzen halbkreisförmige Nuten 64 und 66, die miteinander fluchten und auf einer Seite des Schraubenschaftes 38 angeordnet sind.The edges 30 of the two legs 14 and 16, which project beyond the center, have semicircular grooves 64 and 66 which are aligned with one another and are arranged on one side of the screw shaft 38.

In der Figur 1 und 2 ist zu sehen, wie ein bzw. zwei Anschlußleiter 70, 72 und 74 zwischen dem Grund des U-förmigen Rahmens 12, also zwischen dem Bereich 18 und der Außenfläche des zweiten Schenkels 54 des Druckbügels 50 festgeklemmt werden können. Es besteht auch die Möglichkeit, wie in der Figur 3 ersichtlich, einen Leitungsdraht 76 in die Nuten 64 und 66 einzulegen und zwischen dem ersten Schenkel 52 und der Nut 64 bzw. 66 zu verklemmen.1 and 2 show how one or two connecting conductors 70, 72 and 74 can be clamped between the base of the U-shaped frame 12, that is to say between the region 18 and the outer surface of the second leg 54 of the pressure bracket 50. It is also possible, as can be seen in FIG. 3, to insert a lead wire 76 into the grooves 64 and 66 and to clamp it between the first leg 52 and the groove 64 or 66.

Gemäß Figur 4 kann eine Kamm-Schiene 78 ebenfalls an der Klemme befestigt werden; diese Kamm-Schiene, die als Sammelschiene bei Leitungsschutzschalter-Installationen verwendet wird, ist streifenartig ausgebildet und besitzt Ausnehmungen 80 bzw. 82, mit denen die Leiste 78 zwischen den Kanten 30 der Schenkel 14 und 16 und dem zweiten Schenkel 52 des U-förmigen Druckbügels 50 befestigt werden kann.According to Figure 4, a comb rail 78 can also be attached to the clamp; this comb rail, which is used as a busbar in circuit breaker installations, is designed in the form of a strip and has recesses 80 and 82, respectively, with which the strip 78 between the edges 30 of the legs 14 and 16 and the second leg 52 of the U-shaped pressure bracket 50 can be attached.

In der Figur 5 ist anstatt einer Sammelschiene 78 ein L-förmiges Klemmstück 84 vorgesehen, welches an seinem einen Schenkel gabelartig ausgebildet ist (also eine ähnliche Ausnehmung hat wie die Sammelschiene 78), mit der das Anschlußstück 84 zwischen den freien Schenkelenden 30 und dem ersten Schenkel 52 des Druckbügels befestigt bzw. verklemmt werden kann. Die Ausnehmung bei dem Teil 84 besitzt die Bezugsziffer 86.In FIG. 5, instead of a busbar 78, an L-shaped clamping piece 84 is provided, which is fork-like on its one leg (i.e. has a similar recess as the busbar 78), with which the connection piece 84 between the free leg ends 30 and the first Leg 52 of the pressure bracket can be attached or jammed. The recess in the part 84 has the reference number 86.

Die Herstellung der Klemme kann nun derart erfolgen, daß aus einem Blechstreifen die Ausnehmungen 20 und 22 sowie die beiden Schlitze 24 und 26 ausgestanzt werden. Dann wird der Streifen zu einem U-förmigen Rahmen gebogen, derart, daß die Fortsätze an der Mutter 32 in die beiden Ausnehmungen 20 und 22 eingreifen. Gleichzeitig wird auch der Druckbügel eingesetzt, so daß die beiden Nasen 58 und 60 gleichzeitig mit den Fortsätzen in die Schlitze eingreifen können.The clamp can now be produced in such a way that the cutouts 20 and 22 and the two slots 24 and 26 are punched out of a sheet metal strip. Then the strip is bent into a U-shaped frame such that the extensions on the nut 32 engage in the two recesses 20 and 22. At the same time, the pressure bracket is used so that the two lugs 58 and 60 can simultaneously engage with the extensions in the slots.

Anstatt den ersten Schenkel des U-förmigen Druckbügels 50 gabelartig auszubilden, besteht auch die Möglichkeit, diesen mit einem kreisförmigen Loch zu versehen, durch das dann der Schrau- benschaft bei der Montage hindurchgesteckt werden kann. Anschliessend könnte dieses kreisförmige Loch im Bereich einer Hinterschneidung zwischen dem Gewindebereich des Schaftes und dem Schraubenkopf 42 verengt werden. Die Verengung ist natürlich auch möglich, wenn der erste Schenkel 52 gabelartig mit der Ausnehmung 56 versehen ist. Auf diese Weise wird eine doppelte Unverlierbarkeit bewirkt: Einmal die Unverlierbarkeit aufgrund der Führung der Nasen in den Schlitzen und zum anderen aufgrund der Halterung des Bügels im Bereich der Hinterschneidung zwischen dem Gewindebereich des Schraubenschaftes und dem Kopf.Instead of the first leg of the U-shaped pressure stirrup fork-like form 50, it is also possible to provide it with a circular hole, can be inserted therethrough during assembly benschaft by then the S chrau-. This circular hole could then be narrowed in the region of an undercut between the threaded region of the shaft and the screw head 42. The narrowing is of course also possible if the first leg 52 is provided with the recess 56 in the manner of a fork. In this way, a double captivity is achieved: on the one hand the captivity due to the guidance of the lugs in the slots and on the other hand due to the mounting of the bracket in the area of the undercut between the threaded area of the screw shaft and the head.

Es besteht natürlich auch die Möglichkeit, den Rahmen geschlossen auszubilden, in dem der erste Abschnitt des Rahmens im Bereich seiner Schenkelenden von einem zweiten Abschnitt, der einstückig an einem oder an beiden Schenkeln angeformt ist, überbrückt ist. Es besteht dabei die Möglichkeit, den Rahmen mittels eines Stanz- und Biegeverfahrens oder auch mittels eines Zieh- bzw. Extrudierverfahrens herzustellen und die seitlichen Schlitze nachträglich einzuarbeiten.Of course, there is also the possibility of forming the frame in a closed manner, in which the first section of the frame is bridged in the region of its leg ends by a second section which is integrally formed on one or both legs. It is possible to manufacture the frame by means of a stamping and bending process or also by means of a drawing or extrusion process and to subsequently incorporate the side slots.
