It is provided that the pressure piece (9) in its original position has a point of rotation (12) located at a low level with respect to the clamping point of the terminal spring (4) and, as a consequence of its guide shoulders (13, 14), can be laid obliquely with respect to the terminal body (7) in that the pressure piece (9) is supported on an installation wall (15) adjacent to the terminal limb (5) and the installation point of the foot of the pressure piece can climb up the installation wall. <IMAGE>

Description

Die Erfindung bezieht sich auf eine schraubenlose Anschlußklemme für elektrische Geräte, insbesondere für Installationsgeräte, deren Gehäuse zumindest eine Einführungsöffnung für anzuschließende Leiter aufweist und eine Klemmfeder mit Klemmschenkel sowie einen Klemmkörper aufnimmt. Ein anzuschließender Leiter kann danach zwischen Klemmschenkel und Klemmkörper verklemmt werden. Durch ein im Klemmkörper geführtes Druckstück kann der Klemmschenkel außer Klemmstellung gebracht werden, wodurch sich der Leiter wieder lösen läßt, siehe beispielsweise die DE-A-2 922 477.The invention relates to a screwless terminal for electrical devices, in particular for installation devices, the housing of which has at least one insertion opening for conductors to be connected and which receives a clamping spring with a clamping leg and a clamping body. A conductor to be connected can then be clamped between the clamping leg and the clamping body. By means of a pressure piece guided in the clamping body, the clamping leg can be brought out of the clamping position, as a result of which the conductor can be released again, see for example DE-A-2 922 477.

Derartige schraubenlose Anschlußklemmen sind bekannt (DE-GM 84 24 056, DE-AS 15 75 118). Eine bekannte Anschlußklemme weist einen Klemmschenkel und in Einführungsrichtung für einen anzuschließenden Leiter dahinter einen weiteren Schenkel einer Feder auf, der verrundet gegen den Klemmkörper ansteht und dadurch einen Druckschenkel bildet, der es erlaubt, größere Stromstärken zu übertragen als es allein durch den Klemmschenkel möglich wäre. Um einen angeschlossenen Leiter zu lösen, ist bei der einen bekannten Klemme (DE-GM 84 24 056) ein langes Druckstück vorgesehen, das weit über den Druckkörper hervorragt und unmittelbar hinter der Oberfläche des Klemmkörpers an einer hammerartigen Fortsetzung seinen Drehpunkt findet. Um auf den Klemmschenkel lösend einzuwirken, muß dieses Druckstück weit verschwenkt werden. Ein weit hervorragendes Druckstück ist in der Praxis jedoch häufig störend.Such screwless terminals are known (DE-GM 84 24 056, DE-AS 15 75 118). A known terminal has a clamping leg and in the direction of insertion for a conductor to be connected behind another leg of a spring, which is rounded against the clamping body and thereby forms a pressure leg, which allows larger currents to be transmitted than would be possible through the clamping leg alone. In order to release a connected conductor, a well-known clamp (DE-GM 84 24 056) has a long pressure piece which protrudes far beyond the pressure body and is located at a hammer-like continuation directly behind the surface of the clamp body. To have a loosening effect on the clamping leg, this pressure piece must be pivoted far. In practice, however, a far excellent pressure piece is often annoying.

Nach einer anderen bekannten Anschlußklemme (DE-AS 15 75 118) weist ein Druckstück einen tiefen Drehpunkt auf, wobei das Druckstück noch so weit über den Klemmkörper vorstehen muß, daß ein ausreichender Schwenkweg zum Lösen eines angeschlossenen Leiters ermöglicht wird.According to another known connecting terminal (DE-AS 15 75 118), a pressure piece has a low pivot point, the pressure piece still having to protrude beyond the clamping body so that a sufficient swivel path for releasing a connected conductor is made possible.

Der Erfindung liegt die Aufgabe zugrunde, eine schraubenlose Anschlußklemme zu entwickeln, deren Druckstück gegen den Klemmkörper besonders wenig hervorzustehen braucht und sich dennoch leicht bedienen läßt.The invention has for its object to develop a screwless terminal, the pressure piece needs to protrude particularly little against the clamp body and is still easy to use.

Die Lösung der geschilderten Aufgabe erfolgt nach der Erfindung durch eine Anschlußklemme mit den Merkmalen nach Patentanspruch 1. Danach weist das Druckstück in seiner Ausgangslage einen hinsichtlich der Klemmstelle der Klemmfeder tiefliegenden Drehpunkt auf. Führungsschultern unterhalb des Betätigungskopfes des Druckstücks erlauben, das Druckstück zum Klemmkörper schräg zu legen, wobei die Anlagestelle des Druckstücks an einer seitlichen Anlagewand hochsteigen kann. Dadurch hat ein Bedienender fast den Eindruck, einen horizontalen Schieber zu bedienen, der sich jedoch am Klemmkörper nicht verkanten kann, weshalb das Druckstück leicht zu bedienen ist. Außerdem können so auch dicke Leiter, für die das Druckstück einen großen Weg zurücklegen muß, sicher gelöst werden.According to the invention, the described object is achieved by a connecting terminal with the features according to patent claim 1. According to this, the pressure piece in its starting position has a pivot point that is deep with respect to the clamping point of the clamping spring. Guide shoulders below the actuating head of the pressure piece allow the pressure piece to be inclined to the clamping body, the contact point of the pressure piece being able to rise on a lateral contact wall. As a result, an operator almost has the impression of operating a horizontal slide, which, however, cannot tilt on the clamping body, which is why the pressure piece is easy to operate. In addition, even thick conductors, for which the pressure piece has to travel a long way, can be safely released.

Die Klemmfeder kann mit ihrem Klemmschenkel zur benachbarten Anlagewand einen Winkel einschließen, in dem das Druckstück angeordnet ist. Die Anschlußklemme kann dabei nur einen oder mehrere nebeneinander liegende Klemmschenkel aufweisen oder auch in Einführungsrichtung eines anzuschließenden Leiters hinter einem Klemmschenkel einen weiteren Schenkel aufweisen, der am Klemmkörper verrundet aufsteht und dadurch einen Druckschenkel bildet. Hierbei genügt es, wenn das Druckstück nur auf den bzw. die Klemmschenkel einwirkt.The clamping spring can enclose an angle with its clamping leg to the adjacent contact wall, in which the pressure piece is arranged. The connector can have only one or more clamping legs lying next to one another or also have a further leg behind a clamping leg in the direction of insertion of a conductor to be connected, which stands up rounded on the clamping body and thereby forms a pressure leg. It is sufficient if the pressure piece acts only on the clamping leg or legs.

Das Druckstück kann an seinem Fuß walzenförmig verrundet sein und eine verrundet vorstehende Rippe zum Lösen des Klemmschenkels aufweisen. Dadurch wird die Sicherheit gegen Verkanten beim Betätigen des Druckstücks erhöht.The pressure piece can be rounded in the form of a roller at its base and can have a rounded protruding rib for releasing the clamping leg. This increases the security against tilting when the pressure piece is actuated.

Die Erfindung soll nun anhand von in der Zeichnung grob schematisch wiedergegebenen Ausführungsbeispielen näher erläutert werden:

  • In Figur 1 ist eine Anschlußklemme im Längsschnitt wiedergegeben, bei der das Druckstück in die Position zum Lösen eines eingeführten Leiters gebracht ist.
  • In Figur 2 ist die Anschlußklemme nach Figur 1 in der Ausgangslage, also bei nicht angeschlossenem Leiter wiedergegeben.
  • In Figur 3 ist eine Anschlußklemme ohne Druckstück in Aufsicht auf den Klemmkörper dargestellt.
  • In Figur 4 ist ein Druckstück nach Figur 2 in Seitenansicht wiedergegeben.
  • In Figur 5 ist eine Anschlußklemme mit Klemmschenkel und Druckschenkel veranschaulicht.
  • In Figur 6 ist die Anschlußklemme nach Figur 5 längs eines Schnitts VI-VI dargestellt.
The invention will now be explained in greater detail on the basis of exemplary embodiments shown roughly schematically in the drawing:
  • In Figure 1, a terminal is shown in longitudinal section, in which the pressure piece is brought into the position for releasing an inserted conductor.
  • In Figure 2, the terminal of Figure 1 is shown in the starting position, that is, when the conductor is not connected.
  • In Figure 3, a connection terminal without a pressure piece is shown in supervision of the clamping body.
  • In Figure 4, a pressure piece according to Figure 2 is shown in side view.
  • In Figure 5, a terminal with a clamping leg and pressure leg is illustrated.
  • In Figure 6, the terminal of Figure 5 is shown along a section VI-VI.

Die schraubenlose Anschlußklemme 1 nach Figur 1 weist eine Einführungsöffnung 2 für anzuschließende Leiter 3 auf. Eine weitere Einführungsöffnung kann man sich oberhalb der Zeichenebene vorstellen. Eine Klemmfeder 4 bildet einen Klemmschenkel 5. Ein Gehäuse 6 nimmt die Klemmfeder 4 und einen Klemmkörper 7 auf. Zwischen dem Klemmschenkel 5 der Klemmfeder 4 und dem Klemmkörper 7 können anzuschließende Leiter verklemmt werden, die gegen Herausziehen durch den spitz anstehenden Klemmschenkel 5 in gewohnter Weise gesichert sind. Der Klemmschenkel 5 kann durch ein im Klemmkörper 7 in einem Spalt 8 geführtes Druckstück 9 außer Klemmstellung gebracht werden. Hierzu kann das Druckstück 9 an seinem Betätigungskopf 10 in eine Stellung nach Figur 1 verschwenkt werden. Im Ausführungsbeispiel weist die Anschlußklemme eine Steckbuchse 11 auf, die mit dem Klemmkörper 7 dadurch elektrisch verbunden ist, daß sie einstückig aus diesem geformt ist. Hierzu kann der Klemmkörper mit seinen zurückgebogenen Seitenwänden die Steckbuchse 11 bilden.The screwless connection terminal 1 according to FIG. 1 has an insertion opening 2 for conductors 3 to be connected. Another entry opening can be found above the drawing level. A clamping spring 4 forms a clamping leg 5. A housing 6 accommodates the clamping spring 4 and a clamping body 7. Between the clamping leg 5 of the clamping spring 4 and the clamping body 7, conductors to be connected can be clamped, which are secured against being pulled out by the pointed limb 5 in the usual way. The clamping leg 5 can be brought out of the clamping position by a pressure piece 9 guided in a gap 8 in the clamping body 7. For this purpose, the pressure piece 9 on its actuating head 10 can be pivoted into a position according to FIG. 1. In the exemplary embodiment, the connecting terminal has a socket 11 which is electrically connected to the clamping body 7 in that it is formed in one piece from it. For this purpose, the clamp body with its bent-back side walls can form the socket 11.

Das Druckstück weist in seiner Ausgangslage nach Figur 2 einen hinsichtlich der Klemmstelle der Klemmfeder 4 tief liegenden Drehpunkt 12 auf. Führungsschultern 13 und 14 unterhalb des Betätigungskopfs 10 des Druckstücks 9 führen dieses in einem Spalt 8 des Klemmkörpers 7. Die Führungsschultern sind so geformt, daß das Druckstück 9 zum Klemmkörper 7 schräg gelegt werden kann, wie es aus einem Vergleich der Figuren 2 und 1 zu ersehen ist. Hierbei stützt sich das Druckstück 9 an einer zum Klemmschenkel 5 benachbarten Anlagewand 15 ab. Im Ausführungsbeispiel nach den Figuren 1 und 2 bildet die Anlagewand einen Schenkel der Klemmfeder 4. Während der Auslenkung des Druckstücks, also beim Schrägstellen, steigt dieses an der Anlagewand 15 hoch, wie es in Figur 1 veranschaulicht ist.In its starting position according to FIG. 2, the pressure piece has a pivot point 12 which is deep with respect to the clamping point of the clamping spring 4. Guide shoulders 13 and 14 below the actuating head 10 of the pressure piece 9 guide it in a gap 8 of the clamping body 7. The guide shoulders are shaped so that the pressure piece 9 can be inclined to the clamping body 7, as is the case from a comparison of FIGS. 2 and 1 is seen. Here, the pressure piece 9 is supported on an adjacent to the clamping leg 5 contact wall 15. In the exemplary embodiment according to FIGS. 1 and 2, the contact wall forms one leg of the clamping spring 4. During the deflection of the pressure piece, that is to say when it is inclined, it rises on the contact wall 15, as illustrated in FIG. 1.

Der Klemmschenkel 5 kann für zwei nebeneinander angeordnete Einführungsöffnungen längsgeschlitzt sein, so daß zwei verschiedenartige Leiter sich beim Einklemmen nicht gegenseitig stören. Das Druckstück kann dabei so breit ausgeführt sein, daß es auf beide Klemmschenkel einwirken kann. Ein geschlitzter Klemmschenkel 5 ist in Figur 6 veranschaulicht.The clamping leg 5 can be slotted longitudinally for two insertion openings arranged next to one another, so that two different types of conductors do not interfere with one another when being clamped. The pressure piece can be made so wide that it can act on both clamping legs. A slotted clamping leg 5 is illustrated in Figure 6.

Die Führung des Druckstücks 9 im Spalt 8 des Klemmkörpers 7 ist aus den Figuren 3 und 4 zu ersehen. Der schmale Halsbereich des Druckstücks zwischen seinen Führungsschultern 13 und 14 paßt in den Spalt 8 mit Spiel ein. Um das Druckstück einsetzen zu können, ist der Spalt 8 in einem Teilbereich 16 um das Ausmaß der Breite der Schultern 14 verbreitert.The guidance of the pressure piece 9 in the gap 8 of the clamping body 7 can be seen from FIGS. 3 and 4. The narrow neck area of the pressure piece between its guide shoulders 13 and 14 fits into the gap 8 with play. In order to be able to use the pressure piece, the gap 8 is widened in a partial area 16 by the extent of the width of the shoulders 14.

Die Klemmfeder 4 nach den Figuren 1 und 2 schließt mit ihrem Klemmschenkel 5 zur benachbarten Anlagewand 15 einen Winkel ein, in dem das Druckstück 9 angeordnet ist. Diese Ausführung ist raumsparend und gewährleistet eine sichere Ausgangslage, wenn das Druckstück den Winkelraum ausfüllt.The clamping spring 4 according to FIGS. 1 and 2, with its clamping leg 5, forms an angle with the adjacent contact wall 15 in which the pressure piece 9 is arranged. This version is space-saving and ensures a secure starting position if the pressure piece fills the angular space.

Bei der Anschlußklemme nach Figur 5 ist in Einführungsrichtung eines anzuschließenden Leiters hinter dem Klemmschenkel 5 ein weiterer Schenkel 17 angeordnet, der am Klemmkörper verrundet ansteht, indem er an seinem Ende umgebogen ist. Er bildet dadurch einen Druckschenkel, der einen eingeführten Leiter gegen den Klemmkörper 4 andrückt und wegen des erhöhten Klemmdrucks größere Ströme zu führen erlaubt.In the connecting terminal according to FIG. 5, a further leg 17 is arranged in the direction of insertion of a conductor to be connected behind the clamping leg 5, which leg is rounded on the clamping body by being bent at its end. It thereby forms a pressure leg, which presses an inserted conductor against the clamping body 4 and, because of the increased clamping pressure, allows larger currents to be conducted.

Das Druckstück 9 ist an seinem Fuß bei seinem Drehpunkt 12 walzenförmig verrundet und es weist eine verrundet vorstehende Rippe 18 zum Lösen des Klemmschenkels auf. Hierdurch wird beim Verschwenken und Umlegen des Druckstücks 9 eine besonders sichere Führung erzielt, die ein Verkanten im Spalt 8 des Klemmkörpers 7 sicher vermeiden hilft. Mit der Rippe 18 liegt das Druckstück 9 am Klemmschenkel 5 an. Übersetzende Hebelarme des Druckstücks 9 liegen dabei zwischen dem Betätigungskopf 10 und dem Drehpunkt 12 sowie zwischen der Rippe 18 und dem Drehpunkt 12.The pressure piece 9 is rounded at its base at its pivot point 12 and it has a rounded protruding rib 18 for releasing the clamping leg. As a result, when pivoting and turning the pressure piece 9 achieves a particularly secure guidance which helps to avoid tilting in the gap 8 of the clamping body 7. With the rib 18, the pressure piece 9 rests on the clamping leg 5. Translating lever arms of the pressure piece 9 lie between the actuating head 10 and the fulcrum 12 and between the rib 18 and the fulcrum 12.
