Description

FELD DER ERFINDUNGFIELD OF THE INVENTION

Die vorliegende Erfindung bezieht sich auf das Gebiet der elektrischen Anschlusstechnik; sie betrifft eine Käfigzugklemme gemäss dem Oberbegriff des Anspruchs 1.The present invention relates to the field of electrical connection technology; It relates to a cage clamp according to the preamble of claim 1.

HINTERGRUND DER ERFINDUNGBACKGROUND OF THE INVENTION

Anschlussklemmen für elektrische Installationen sind in verschiedensten Ausführungsformen aus dem Stand der Technik bekannt. Ein wesentliches Unterscheidungskriterium besteht in der Art der Fixierung eines Kabels oder eines Leiters in solchen Anschlussklemmen, namentlich mittels einer Feder oder einer Schraube. Im vorliegenden Fall wird eine Anschlussklemme betrachtet, bei der eine Schraubverbindung mit einer Käfigzugklemme zusammenwirken.Terminals for electrical installations are known in various embodiments from the prior art. An essential distinguishing criterion consists in the type of fixation of a cable or a conductor in such terminals, namely by means of a spring or a screw. In the present case, a terminal is considered, in which a screw connection with a cage clamp together.

Aus der DE 693 02 103 ist eine Anschlussklemme bekannt, bei welcher ein aus einem metallischen Leiterwerkstoff bestehender, geschlossener Käfig einen annähernd rechteckigen Rahmen mit einem Grund, zwei Seitenstegen und einer Oberseite aufweist, wobei die Oberseite als eine mit Gewindebohrung versehene Schraubenmutter ausgebildet ist. Der Grund des Käfigs dient als eine erste Klemmfläche. Ein Kontaktbügel mit einer zweiten Klemmfläche ist derart in den Käfig eingefügt, dass zwischen der ersten und der zweiten Klemmfläche ein oder mehrere elektrische Leiter verklemmt werden können.From the DE 693 02 103 a terminal is known in which an existing of a metallic conductor material, closed cage has an approximately rectangular frame with a bottom, two side bars and a top, wherein the top is formed as a threaded bore nut. The bottom of the cage serves as a first clamping surface. A contact clip with a second clamping surface is inserted into the cage in such a way that one or more electrical conductors can be clamped between the first and the second clamping surface.

Die FR 253 55 34 offenbart ebenfalls eine Anschlussklemme mit einem geschlossenen Käfig, bestehend aus einem Grund, zwei Seitenstegen und einer Oberseite mit Gewindebohrung für eine Schraube. Diese Anschlussklemme bietet die Möglichkeit im Inneren des Käfigs ein Kabel zwischen zwei Klemmflächen zu fixieren oder eine Stromschiene zwischen der Schraube und einer dritten, an der Aussenseite des Käfigs liegende Klemmfläche anzuschliessen.The FR 253 55 34 also discloses a terminal with a closed cage, consisting of a base, two side bars and a threaded top for a screw. This terminal offers the possibility in the Inside the cage to fix a cable between two clamping surfaces or connect a power rail between the screw and a third, lying on the outside of the cage clamping surface.

Die aus der EP 336 251 bekannte Anschlussklemme zeigt einen Klemmenrahmen mit einer äusseren Klemmfläche und einen Kastenrahmen mit einer inneren Klemmfläche, zwischen denen ein Leiter fixierbar ist. Der Klemmenrahmen und der Kastenrahmen sind so ineinander verschachtelt, dass beim Verschrauben des Leiters auch die beiden Rahmen miteinander verbunden werden. Der Kastenrahmen wird im Wesentlichen von dem Klemmenrahmen umfasst und ist als geschlossener Käfig mit Grund, zwei Seitenstegen und einer Oberseite ausgebildet. Auch hier weist die Oberseite eine Gewindebohrung für die Aufnahme einer Schraube auf. Der Grund ist hier bogenförmig geformt; seine Innenseite dient als die oben genannte, innere Klemmfläche.The from the EP 336,251 known terminal shows a terminal frame with an outer clamping surface and a box frame with an inner clamping surface, between which a conductor is fixed. The terminal frame and the box frame are interlaced so that when screwing the conductor and the two frames are connected to each other. The box frame is substantially encompassed by the clamp frame and is formed as a closed cage with bottom, two side bars and a top. Again, the top has a threaded hole for receiving a screw. The reason is here arched; its inside serves as the above-mentioned inner clamping surface.

In der EP 59 939 ist eine Käfigzugklemme mit einem U-profilförmigen Käfig offenbart, der einen ersten und einen zweiten Schenkel und einen diese beiden Schenkel einseitig verbindenden Steg umfasst, wobei diese Schenkel jeweils ein zueinander fluchtendes Schenkelfenster aufweisen. Zwischen den Schenkeln ist eine Mutter einsetzt, die mit an ihr angeordneten Fortsätzen in den Schenkelfenstern geführt gelagert ist. Eine Schraube, die in diese Mutter eingreift stützt sich mit ihrem Schraubenkopf auf einer Druckplatte ab, die die beiden Schenkel des offenen Käfigs überdeckt. Die Innenseite des U-profilförmigen Käfigs dient als eine Klemmfläche für eingeführte Leiter.In the EP 59 939 discloses a cage clamp with a U-shaped cage, comprising a first and a second leg and a bridge connecting these two legs on one side, said legs each having a mutually aligned leg window. Between the legs, a nut is inserted, which is mounted guided with her extensions in the leg windows. A screw, which engages in this nut is supported with its screw head on a pressure plate, which covers the two legs of the open cage. The inside of the U-shaped cage serves as a clamping surface for inserted conductors.

Allen vorgestellten Anschlussklemmen ist gemeinsam, dass sie eine Mehrzahl von Einzelteilen aufweisen und/oder in sich geschlossene Käfige, womit die Herstellung solcher Anschlussklemmen entsprechend aufwendig ist. Des Weiteren weisen die damit fixierten Kabel eine vergleichsweise grosse Berührungsfläche zur Klemmfläche der Anschlussklemme im Verhältnis zum Leiterquerschnitt aufweisen, womit sich bei vorgegebenem Drehmoment als Anzugsmoment der Schraube ein hierzu entsprechend maximaler Anpressdruck an die Klemmfläche der Anschlussklemme ergibt. Dieser Anpressdruck an die Klemmfläche der Anschlussklemmen kann unter besonderen, äusseren Einflüssen -wie beispielsweise Drehen des angeschlossenen Leiters- nicht vollständig ausreichend sein, um ein Lösen solcher Verbindungen ohne Aufzuschrauben zu verhindern. Eine Abhilfe dieser Nachteile stellt die vorliegende Erfindung dar.Allen presented terminals is common that they have a plurality of individual parts and / or self-contained cages, making the preparation of such terminals is correspondingly expensive. Furthermore, the thus fixed cables have a comparatively large contact surface to the clamping surface of the terminal in relation to the conductor cross-section, which at a given torque as a tightening torque of the screw corresponding thereto a maximum contact pressure to the clamping surface of the terminal results. This contact pressure on the clamping surface of the terminals can under certain external influences -such as turning the connected conductor- not be completely sufficient to prevent loosening of such compounds without unscrewing. A remedy for these disadvantages is the present invention.

DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION

Es ist daher Aufgabe der Erfindung, eine Anschlussklemme in Form einer Käfigzugklemme zu schaffen, welche die Nachteile bekannter Anschlussklemmen vermeidet und sich insbesondere durch einen vereinfachten Aufbau, eine einfache Montage, eine geringe Anzahl von Teilen und eine sichere Verbindung auszeichnet.It is therefore an object of the invention to provide a terminal in the form of a cage clamp, which avoids the disadvantages of known terminals and is characterized in particular by a simplified structure, easy installation, a small number of parts and a secure connection.

Die Aufgabe wird durch die Gesamtheit der Merkmale des Anspruchs 1 gelöst. Für die Erfindung wesentlich ist, dass eine Käfigzugklemme einen U-profilförmigen Käfig aufweist, der einen ersten und einen zweiten Schenkel und einen diese beiden Schenkel einseitig verbindenden Steg umfasst, wobei diese Schenkel jeweils ein zueinander fluchtendes Schenkelfenster aufweisen und der Steg eine Gewindebohrung zur Aufnahme einer Schraube aufweist, womit mindestens ein durch die beiden Schenkelfenster eingeführter Leiter sicher verklemmbar ist; im Vergleich zum vorgenannten Stand der Technik ist die Klemmfläche bzw. sind die Klemmflächen zwischen der Käfigzugklemme und dem oder den Leitern bedeutend kleiner.The object is solved by the entirety of the features of claim 1. It is essential for the invention that a cage clamp has a U-shaped cage comprising a first and a second leg and a web connecting these two legs on one side, said legs each having a mutually aligned leg window and the web has a threaded bore for receiving a Has screw, whereby at least one inserted through the two leg window conductor is securely clamped; Compared to the aforementioned prior art, the clamping surface (s) between the cage clamp and the conductor (s) is significantly smaller.

Eine bevorzugte Ausgestaltung der erfindungsgemässen Käfigzugklemme zeichnet sich dadurch aus, dass der die beiden Schenkel verbindende Steg bogenförmig ausgebildet ist.A preferred embodiment of the cage clamp according to the invention is characterized in that the web connecting the two limbs is arc-shaped.

Eine solche bogenförmige Geometrie des Stegs ist bei Verschraubung der Klemme besonders formstabil, bzw. biegesteif.Such arcuate geometry of the web is particularly dimensionally stable when screwing the terminal, or rigid.

Gemäss einer vorteilhaften Ausgestaltung der Erfindung weist mindestens eines der Schenkelfenster eine im wesentlichen rechtwinkelige Schenkelfensterrahmenstruktur auf, wobei ein erstes, kurzes Rahmensegment auf der dem Steg zugewandten Seite liegt und eine zweites, kurzes Rahmensegment an einer einem Schenkelende zugewandten Seite angeordnet ist und diese beiden kurzen Rahmensegmente mittels zweier langer Rahmensegmente verbunden sind; die beiden langen Rahmensegmente sind zum Steg hin im Wesentlichen rechtwinkelig zum ersten, kurzen Rahmensegment angeordnet und zum zweiten, kurzen Rahmensegment hin sind sie abgeschrägt; mit Vorteil sind die langen Rahmensegmente zum zweiten, kurzen Rahmensegment hin achsensymmetrisch zur Schraube abgeschrägt.According to an advantageous embodiment of the invention, at least one of the leg window has a substantially rectangular leg window frame structure, wherein a first, short frame segment lies on the side facing the web and a second, short frame segment is arranged on a leg end facing side and these two short frame segments are connected by means of two long frame segments; the two long frame segments are arranged to the web substantially perpendicular to the first, short frame segment and the second, short frame segment out they are chamfered; Advantageously, the long frame segments to the second, short frame segment are skewed axially symmetrical to the screw.

Die Abschrägung der beiden langen Rahmensegmente zum zweiten, kurzen Rahmensegment hin sollte mindestens in einem Winkel von 15° und höchstens in einem Winkel von 60° verlaufen, und zwar von einer gedachten Linie zum jeweiligen Schenkelende hin betrachtet in Verlängerung des jeweiligen langen Rahmensegments; mit besonderem Vorteil beträgt der Winkel 30°.The bevel of the two long frame segments to the second, short frame segment should extend at least at an angle of 15 ° and at most at an angle of 60 °, as viewed from an imaginary line to the respective leg end in extension of the respective long frame segment; with particular advantage, the angle is 30 °.

Eine weitere vorteilhaft Ausgestaltung der Erfindung sieht vor, dass die Materialstärke des U-profilförmigen Käfigs kleiner ist, als der Abstand der beiden Schenkel voneinander. In diesem Fall ist die Auflage eines Leiters an der oder den Klemmflächen des Käfigs geprägt von der Kantenwirkung der Schenkel, insbesondere gegenüber dem zweiten, kurzen Rahmensegment, was den Leiter im verschraubten Zustand gegenüber der Käfigzugklemme besonders verdrehsicher macht.A further advantageous embodiment of the invention provides that the material thickness of the U-shaped cage is smaller than the distance between the two legs from each other. In this case, the support of a conductor on the clamping surface or surfaces of the cage is characterized by the edge effect of the legs, in particular with respect to the second, short frame segment, which makes the conductor in the screwed state with respect to the cage pull terminal particularly secure against rotation.

Die erfindungsgemässe Käfigzugklemme zeichnet sich vor allem dadurch aus, dass mit ihr in Form einer Standardklemme mit vorgegebener, fester Standardgrösse Kabel mit einem Kabelquerschnitt zwischen 2 und 50 Quadratmillimetern sicher verschraubbar sind, ohne dass die Klemmengrösse als solche einer Geometrieänderung unterzogen werden müsste.The cage clamp according to the invention is characterized in particular by the fact that it can be screwed securely with it in the form of a standard clamp with predetermined, fixed standard size cables with a cable cross section between 2 and 50 square millimeters, without the clamp size as such would have to undergo a geometry change.

Gemäss einer anderen Ausgestaltung der Erfindung ist ein in die beiden Schenkelfenster eingeführter Leiter ein Kabel und ferner ist zwischen diesem Kabel und dem Schraubenende eine Stromschiene angeordnet, die bei verschraubter Käfigzugklemme mit dem Kabel eine elektrische Verbindung eingeht.According to another embodiment of the invention, an inserted into the two leg window conductor is a cable and also a bus bar is arranged between this cable and the end of the screw, which forms an electrical connection with screwed cage clamp with the cable.

Gemäss einer weiteren Ausgestaltung der Erfindung weist das erste, kurze Rahmensegment erste Ausnehmungen für eine verbesserte Kraftverteilung aufweist; mit gleichem Hintergrund kann der Käfig seitlich am Steg zweite Ausnehmungen aufweisen, und/oder die langen Rahmensegmente dritte Ausnehmungen, die ein Einführen des Leiters erleichtern.According to a further embodiment of the invention, the first, short frame segment has first recesses for an improved force distribution; with the same background, the cage can have second recesses on the side of the web, and / or the long frame segments have third recesses which facilitate insertion of the conductor.

In dieser Ansicht ist ebenfalls das Schraubenende 24 der Schraube 27 sichtbar. Hervorzuheben ist, dass die Materialstärke 21 des Käfigs 23 kleiner ist, als der Abstand 22 der benachbarten Schenkel 11a, b. Dieses Bemassungsverhältnis zwischen Materialstärke 21 und Abstand der Schenkel 11a, b ist für die sichere Funktion der erfindungsgemässen Käfigzugklemme 10 von Bedeutung.In the Fig. 2 a side view of the cage clamp 10 is shown, in which the U-shaped cage 23 with its arcuate web 12 and the legs 11 a, b are illustrated. In this view, the screw end 24 of the screw 27 is also visible. It should be emphasized that the material thickness 21 of the cage 23 is smaller than the distance 22 of the adjacent legs 11a, b. This dimensioning ratio between the thickness of the material 21 and the distance between the legs 11a, b is important for the safe operation of the cage clamp 10 according to the invention.

In der perspektivischen Darstellung der Fig. 3 sind zwei, in die Schenkelfenster 13a, b eingeführte elektrische Leiter 14a, b gezeigt, nämlich ein Kabel 14a und eine zwischen diesem Kabel 14a und dem hier nicht sichtbaren Schraubenende (24, siehe Fig. 2) angeordnete Stromschiene 14b. Ebenfalls deutlich wird die Wirkung des zweiten, kurzen Rahmensegments 17 in Verbindung mit den Abschrägungen 33, deren Kante 28 im verschraubten Zustand der Käfigzugklemme eine gegenüber dem aufgezeigten Stand der Technik wesentlich verbesserte Klemmwirkung ermöglicht.In the perspective view of Fig. 3 are two, in the leg windows 13a, b introduced electrical conductors 14a, b shown, namely a cable 14a and between this cable 14a and the not visible here screw end (24, see Fig. 2 ) arranged busbar 14b. Also clear is the effect of the second, short frame segment 17 in conjunction with the chamfers 33, the edge 28 in the screwed state of the cage clamp allows a comparison with the prior art much improved clamping effect.

Eine weitere Seitenansicht der Käfigzugklemme in Fig. 4 zeigt die durch das Schraubenende 24 der Schraube 27 miteinander fixierten Leiter 14a, b, wobei sich das Kabel 14a in die wannenförmige Struktur, gebildet aus dem zweiten, kurzen Rahmensegment 17 und den angrenzenden Abschrägungen 33 der langen Rahmensegmente 19a, b, einfügt. Die Abschrägungen 33 weisen zu einer Linie 29 einen Winkel α auf, wobei diese Linie 29 eine gedachte Verlängerung der langen Rahmensegmente 19a, b zu den jeweils freien Schenkelenden 18 hin darstellt und zudem die Abschrägungen 33 achsensymmetrisch zu einer Symmetrieachse 20 der Schraube 27 an beiden langen Rahmensegmenten 19a, b angeordnet sind. Dieser Winkel α sollte zwischen 15° und 60° betragen; besonders gute - sprich sichere- Eigenschaften der Verschraubung zeigen sich mit der erfindungsgemässen Käfigzugklemme, wenn der Winkel α 30° beträgt.Another side view of the cage clamp in Fig. 4 shows the conductors 14a, b fixed together by the screw end 24 of the screw 27, the cable 14a fitting into the trough-shaped structure formed by the second short frame segment 17 and the adjacent bevels 33 of the long frame segments 19a, b. The Chamfers 33 have an angle α to a line 29, this line 29 is an imaginary extension of the long frame segments 19a, b to the respective free leg ends 18 out and also the chamfers 33 axisymmetric to an axis of symmetry 20 of the screw 27 at two long frame segments 19a, b are arranged. This angle α should be between 15 ° and 60 °; Particularly good - that is safe - properties of the screw are shown with the inventive cage clamp, when the angle α is 30 °.

Die Fig. 5 und 6 zeigen Ausführungsvarianten der oben in Zusammenschau mit den Fig. 1 bis 4 beschriebnen Käfigzugklemme 10. Dabei weist der Käfig 23 funktionsoptimierende Ausnehmungen 30, 31 und 32 auf.The FIGS. 5 and 6 show embodiments of the above in conjunction with the Fig. 1 to 4 described cage retainer 10. In this case, the cage 23 has function-optimizing recesses 30, 31 and 32 on.

Die Ausnehmungen 30 und 31 sind am Steg 12 angeordnet und bewirken eine -hier nicht dargestellte- verbesserte Kraftverteilung innerhalb des Käfigs 23, wenn die Schraube 27 angezogen ist; und zwar sind hierfür halbkreisförmige Ausnehmungen 30 an den beiden Ecken zwischen dem ersten, kurzen Rahmensegment 16 und den angrenzenden langen Rahmensegmenten 19a, b vorgesehen. Mit gleicher Wirkung sind die beiden freien Kanten des Stegs 12 mit Ausnehmungen 31 versehen.The recesses 30 and 31 are arranged on the web 12 and cause a -here not shown- improved power distribution within the cage 23 when the screw 27 is tightened; For this purpose, semicircular recesses 30 are provided at the two corners between the first, short frame segment 16 and the adjacent long frame segments 19a, b. With equal effect, the two free edges of the web 12 are provided with recesses 31.

Weitere Ausnehmungen 32 sind an den Innenseiten der langen Rahmensegmente 19a, b vorgesehen; sie vereinfachen ein Einführen von Kabeln 14a mit grossen Querschnitten in die Schenkelfenster 13a, b, in dem sie eine entsprechende geometrische Erweiterung der Schenkelfensterrahmenbreite bereitstellen.Further recesses 32 are provided on the inner sides of the long frame segments 19a, b; they facilitate insertion of large diameter cables 14a into the leg windows 13a, b by providing a corresponding geometric extension of the leg window frame width.

Insgesamt ergibt sich mit der Erfindung eine einfach aufgebaute und leicht zu montierende Anschlussklemme, die mit wenigen Einzelteilen auskommt und eine besonders sichere Verschraubung ermöglicht.Overall, with the invention results in a simple design and easy to install terminal, which requires only a few parts and allows a particularly secure screwing.
