Description

Die Erfindung bezieht sich auf eine Anschlußklemme für elektrische Geräte mit besonders niedriger Bauform, deren Klemmschraube in einem Klemmsockel gehalten ist und die eine Schelle zum Gegenhalten gegen die Auflagefläche am Klemmsockel aufweist, die zusammen zumindest einen Klemmplatz für anzuschließende Leiter bilden.The invention relates to a terminal for electrical devices with a particularly low design, the clamping screw is held in a clamping base and has a clamp to hold against the bearing surface on the terminal base, which together form at least one terminal space for conductors to be connected.

Elektrische Installationsgeräte wie Fehlerstromschutzschalter, Leitungsschutzschalter und Sicherungstrennschalter werden immer häufiger sehr niedrig ausgebildet, um auch in Verteilungsgehäusen in dünnen Wänden untergebracht werden zu können. Die Anschlußklemmen für die anzuschließenden Leiter beanspruchen dann bei üblicher Ausführung viel Bauhöhe. Besonders problematisch ist das Anschließen von zwei Leitern, deren Durchmesser stark differieren.Electrical installation devices such as residual current circuit breakers, miniature circuit breakers and fuse disconnectors are increasingly being designed very low so that they can also be housed in thin-walled distribution boxes. The terminals for the conductors to be connected then require a lot of height in the usual design. Connecting two conductors whose diameters differ greatly is particularly problematic.

Der Aufbau von sogenannten Flachklemmen ist beispielsweise nach DIN 4100, Februar 1975, dargestellt. Dabei können zwei Leiter mit unterschiedlichen Durchmessern nur dann angeschlossen werden, wenn die Durchmesser in einem der festgelegten Bereiche liegen, deren Spielraum häufig unbefriedigend eng ist. Die Klemmschraube überragt dabei die anzuschließenden Leiter, so daß die Klemme noch viel Bauhöhe beansprucht.The structure of so-called flat clamps is shown, for example, according to DIN 4100, February 1975. Two can Conductors with different diameters can only be connected if the diameters lie in one of the defined areas, the scope of which is often unsatisfactorily narrow. The clamping screw protrudes above the conductor to be connected, so that the terminal still requires a lot of height.

Der Erfindung liegt die Aufgabe zugrunde, eine Anschlußklemme zu entwickeln, die besonders niedrig ist, die Einzelleiter wie auch Leiter mit unterschiedlichen Durchmessern sicher anzuschließen gestattet und die sich leicht bedienen läßt.The invention has for its object to develop a terminal that is particularly low, the individual conductors as well as conductors with different diameters can be safely connected and which is easy to use.

Die Lösung der geschilderten Aufgabe liegt in einer Anschlußklemme mit den Merkmalen des kennzeichnenden Teils von Anspruch 1. Wesentlich ist also, daß der Klemmplatz jeweils von der Klemmschraube soweit entfernt ausgebildet ist, daß für den größten anschließbaren Leiter noch ein Abstand von etwa dem halben Durchmesser dieses Leiters verbleibt. Weiter ist die Schelle um die Klemmschraube soweit kippbeweglich zu halten, daß sich ein Schellenarm auf der zum Klemmplatz gegenüberliegenden Seite -der Klemmschraube auf dem Klemmsockel abstützen kann. Der niedrige Aufbau wird dabei durch eine Klemmschraube gefördert, die mit ihrem Kopf in der Schelle versenkbar ausgebildet ist. Durch die erfindungsgemäße Anschlußklemme greift der Kopf der Klemmschraube auch bei hinsichtlich des Klemmsockels schräg gestellter Schelle nahezu unverändert am Angriffspunkt an. Bei einer Schelle mit gleich langen Schellenarmen greift der Schraubenkopf in allen Betriebslagen etwa in der Mitte an: Auch bei anzuschließenden Leitern mit unterschiedlichem Durchmesser bleiben die Klemmkräfte daher gut erhalten bzw. bei zwei anzuschließenden Leitern gut verteilt.The solution to the described problem lies in a connection terminal with the features of the characterizing part of claim 1. It is therefore essential that the clamping location is so far removed from the clamping screw that for the largest connectable conductor there is still a distance of approximately half the diameter of this Leader remains. Furthermore, the clamp is to be held so that it can be tilted so far that a clamp arm can be supported on the side opposite the clamping position - the clamping screw on the clamping base. The low structure is promoted by a clamping screw, which is designed to be retractable with its head in the clamp. By means of the connecting clamp according to the invention, the head of the clamping screw engages almost unchanged at the point of application even when the clamp is inclined with respect to the clamping base. In the case of a clamp with clamp arms of the same length, the screw head engages approximately in the middle in all operating positions: Even with conductors with different diameters to be connected, the clamping forces are therefore well preserved or well distributed with two conductors to be connected.

Die Anschlußklemme wird gegen Lockern unter verschiedenartigen Betriebsbedingungen besonders gesichert, wenn die Schelle als elastisches Formteil ausgebildet wird. Es ist dabei günstig, daß zwei Klemmplätze durch Kröpfen zweier gegenüberliegender Ränder der Schelle ausgebildet sind und daß zwischen diesen Klemmplätzen ein Druchgriff für die Klemmschraube in einer Mulde ausgebildet ist, deren Neigung im gedachten Achsenkreuz in Richtung der gekröpften Ränder etwa der Neigung des als Senkkopf ausgebildeten Kopfes der Klemmschraube entspricht und daß die Neigung in Richtung senkrecht zu den gekröpften Rändern flacher als die Neigung des Senkkopfes ausgebildet ist. Eine solche Schelle weist, besonders wenn sie als Formteil ausgebildet ist, elastische Schellenarme auf, wobei die Schelle jeweils am Klemmplatz für die anzuschließenden Leiter versteift ist und den Leitern seitlich Halt gibt.The terminal is particularly secured against loosening under various operating conditions if the clamp is designed as an elastic molded part. It is advantageous that two clamping locations are formed by cranking two opposite edges of the clamp and that between these clamping locations a handle for the clamping screw is formed in a trough, the inclination of which in the imaginary axis cross towards the cranked edges approximately the inclination of the countersunk head Head of the clamping screw corresponds and that the inclination in the direction perpendicular to the cranked edges is flatter than the inclination of the countersunk head. Such a clamp, especially if it is designed as a molded part, has elastic clamp arms, the clamp being stiffened at the terminal location for the conductors to be connected and providing lateral support for the conductors.

Besonders elastisch und zugleich stabil hinsichtlich anzuschließender Leiter ist die Anschlußklemme, wenn die Klemmplätze durch in der Schelle zwischen ihrem oberen Muldenrand und dem abgekröpften Rand ausgebildete konvexe Führungsrinnen gebildet sind, deren Scheitel näher am Rand als am gedachten Achsenkreuz des Durchgriffes für die Klemmschraube liegt.The connection terminal is particularly elastic and at the same time stable with regard to the conductor to be connected if the terminal locations are formed by convex guide troughs formed in the clamp between their upper trough edge and the bent edge, the apex of which lies closer to the edge than to the imaginary crosshair of the penetration for the clamping screw.

Man spart Material und erzielt Führung in einemInstalla- tionsgerät,wenn die Schelle in ihrem Grundriß im wesentlichen rechteckig ist, wobei ihre Längsseite zwischen den abgekröpften Seiten verläuft und wenn sie Führungsnasen bildet.Material is saved and guidance is achieved in an installation device if the clamp is essentially rectangular in plan, its long side runs between the bent sides and if it forms guide lugs.

The invention will be explained in greater detail on the basis of exemplary embodiments shown roughly schematically in the drawing:
  • A connecting terminal with a connected conductor is illustrated in longitudinal section in FIG. 1. The terminal base is shown broken off on its sides.
  • FIG. 2 shows the top view of an exemplary embodiment of the clamp for the connecting terminal according to FIG. 1.

FIG. 7 shows the top view of the connection terminal according to FIG. 6, but in an uncut state.

Die Anschlußklemme nach Figur 1 weist eine Klemmschraube 1 auf, die in einer Gewindebohrung im Klemmsockel 2 gehalten ist. Eine Schelle 3 dient zum Gegenhalten gegen die Auflagefläche des Klemmsockels 2. Zwischen Schelle 3 und Klemmsockel 2 liegen im Ausführungsbeispiel zwei Klemmplätze. Im linken Klemmplatz ist ein Leiter 4 gehalten, der beispielsweise einen Querschnitt von 16 mm2 aufweist. Dieser Klemmplatz ist von der Klemmschraube 1 so weit entfernt ausgebildet, daß für den größten anschließbaren Leiter 4 noch ein. Abstand 5 von etwa dem halben Durchmesser dieses Leiters verbleibt. Die Schelle 3 ist um die Klemmschraube 1 so weit kippbeweglich gehalten, daß sich ein Schellenarm auf der zum Klemmplatz, beispielsweise für den Leiter 4, gegenüberliegenden Seite der Klemmschraube 1 auf dem Klemmsockel 2 abstützen kann. Die Klemmschraube 1 ist mit ihrem Kopf in der Schelle 3, beispielsweise wie aus der Darstellung ersichtlich, versenkbar ausgebildet.1 has a clamping screw 1, which is held in a threaded bore in the clamping base 2. A clamp 3 is used to hold against the bearing surface of the clamping base 2. In the exemplary embodiment, two clamping locations lie between the clamp 3 and the clamping base 2. A conductor 4, which for example has a cross section of 16 mm 2 , is held in the left terminal position. This terminal place is so far away from the clamping screw 1 that for the largest connectable Head 4 still one. Distance 5 of about half the diameter of this conductor remains. The clamp 3 is held so that it can tilt about the clamping screw 1 so that a clamp arm can be supported on the clamping base 1 on the side opposite the clamping screw 1, for example for the conductor 4, on the clamping base 2. The clamping screw 1 is designed with its head in the clamp 3, for example as shown in the illustration, retractable.

Im Ausführungsbeispiel nach Figur 1 sind zwei Klemmplätze durch kröpfen zweier gegenüberliegender Ränder 8 der Schelle 3 ausgebildet. Zwischen diesen Klemmplätzen ist ein Durchgriff 9 für die Klemmschraube 1 in einer Mulde 10 ausgebildet, deren Neigung im gedachten Achsenkreuz 11, nach Figur 2, in Richtung 12 der gekröpften Ränder etwa der Neigung des als Senkkopf 13 ausgebildeten Kopfes der Klemmschraube entspricht. Die Neigung in Richtung 14 senkrecht zu den gekröpften Rändern 8 ist flacher als die Neigung des Senkkopfes 13 ausgebildet. Man vergleiche Figur 3.In the exemplary embodiment according to FIG. 1, two clamping locations are formed by cranking two opposite edges 8 of the clamp 3. Between these clamping locations, a passage 9 for the clamping screw 1 is formed in a trough 10, the inclination of which in the imaginary axis cross 11, according to FIG. The inclination in the direction 14 perpendicular to the cranked edges 8 is flatter than the inclination of the countersunk head 13. Compare Figure 3.

Die Schelle nach Figur 2 für die Klemmplätze der Anschlußklemme ist in ihrem Grundriß im wesentlichen rechteckig, wobei ihre Längsseite zwischen den abgekröpften Seiten 8 verläuft. Sie hat Führungsnasen 15 zum Einbau in ein Installationsgerät. An der Stirnseite kann das Einführen anzuschließender Leiter durch Anlaufschrägen 16 erleichtert werden.The clamp of Figure 2 for the terminal locations of the terminal is essentially rectangular in plan, with its long side between the cranked sides 8. It has guide lugs 15 for installation in an installation device. The introduction of conductors to be connected can be facilitated by bevels 16 on the end face.

Die Vorderansicht der Schelle nach Figur 2 ist in Figur 3 wiedergegeben. Die Klemmplätze sind durch in der Schelle zwischen ihrem oberen Muldenrand 17 und dem abgekröpften Rand 8 ausgebildete konvexe Führungsrinnen 18 gebildet, deren Scheitel 19 näher am Rand 8 als am gedachten Achsenkreuz 11, nach Figur 2, des Durchgriffs 9 für die Klemmschraube liegt.The front view of the clamp according to FIG. 2 is shown in FIG. 3. The pinch points are through in the clamp between their upper trough edge 17 and the cranked Edge 8 formed convex guide troughs 18, the apex 19 of which is closer to the edge 8 than to the imaginary axis cross 11, according to FIG. 2, of the opening 9 for the clamping screw.

In Figur 4 ist veranschaulicht, wie ein Leiter 4 mit größtem Durchmesser und ein Leiter 6 mit mittlerem bis kleinem Durchmesser festgeklemmt werden können. Die Darstellung nach Figur 5 zeigt, wie ein Leiter 4 mit größtem Durchmesser - beispielsweise ein Querschnitt von 16,mm2 - und ein Leiter 7 mit kleinem Durchmesser - beispielsweise ein Querschnitt von 4 mm2 - festgeklemmt werden können. Wesentlich ist, daß die Schelle 3 am Senkkopf 13 der Klemmschraube 1 sowohl in der Betriebsweise nach Figur 1 als auch in der nach den Figuren 4 oder 5 jeweils im Bereich der Mittellinie 20, der gedachten Achse der Klemmschraube 1, anliegt. Um die Schelle 3 bis zum Anschlag des Muldenrandes am Senkkopf 13 frei kippen zu lassen, ist verständlicherweise zwischen Klemmschraube 1 und Durchgriff 9 für die Klemmschraube 1 ausreichend Spiel zu belassen.FIG. 4 illustrates how a conductor 4 with the largest diameter and a conductor 6 with a medium to small diameter can be clamped. The illustration in FIG. 5 shows how a conductor 4 with the largest diameter - for example a cross section of 16 mm 2 - and a conductor 7 with a small diameter - for example a cross section of 4 mm 2 - can be clamped. It is essential that the clamp 3 rests on the countersunk head 13 of the clamping screw 1 both in the operating mode according to FIG. 1 and in that according to FIGS. 4 or 5 in the region of the center line 20, the imaginary axis of the clamping screw 1. In order to allow the clamp 3 to tilt freely up to the stop of the trough edge on the countersunk head 13, it is understandable that there is sufficient play between the clamping screw 1 and the penetration 9 for the clamping screw 1.

Die Anschlußklemme im Ausführungsbeispiel nach Figur 6 weist einen Klemmsockel mit seitlich heruntergezogenen Flanken 21 auf. In der Darstellung nach Figur 6 sind einige Leiter verschiedener Durchmesser veranschaulicht. Den Einsatz in einem niedrigen und zugleich schmalen Installationsgerät 30 wird in Figur 7 weiter veranschaulicht. Hierbei ist das Installationsgerät 30 abgebrochen dargestellt.The connecting terminal in the exemplary embodiment according to FIG. 6 has a clamping base with flanks 21 which are pulled down to the side. Some conductors of different diameters are illustrated in the illustration according to FIG. The use in a low and at the same time narrow installation device 30 is further illustrated in FIG. 7. Here, the installation device 30 is shown broken off.
