Abstract

A device for establishing a current-conducting connection between a strip-shaped conducting member and one or more wire-like conductors has a reinforced frame with two mutually inclined internal surfaces which make an angle of 30 degrees. The conducting member is placed against one of the internal surfaces and the conductor or conductors are placed adjacent the conducting member in the interior of the frame. A screw whose axis halves the angle between the two internal surfaces meshes with the frame and carries a clamping element which has an elongated slot for the shank of the screw and which slides along the other internal surface of the frame in response to rotation of the screw to move the clamping element in the direction of convergence of the internal surfaces whereby the clamping element bears against the conductor or conductors and urges them against the conducting member so that the latter is biased against the one internal surface. The slot enables the clamping element to move transversely of the axis of the screw, for example, to become disengaged from the conductor or conductors when the screw is rotated to move the clamping element counter to the direction of convergence of the internal surfaces. The angle between the axis or axes of the conductor or conductors and the axis of the screw is approximately or exactly 15 degrees.

Description

Die vorliegende Erfindung bezieht sich auf ein Verbindungselement zur elektrisch leitenden Verbindungs eines Steckerstiftes mit einem Leiterdraht gemäss dem Oberbegriff des Anspruchs 1.The present invention relates to a connecting element for the electrically conductive connection of a plug pin to a conductor wire according to the preamble of claim 1.

Ein solches Verbindungselement ist beispielsweise aus der EP-A-00 73 275 bekannt. Bei diesem älteren Verbindungselement besteht der Körper aus einem Bügel, der einen Anlageschenkel und eine halbkreisförmige Nut sowie ein Mittelstück aufweist, wobei die Nut durch einen Schenkelstumpf des Bügels gebildet ist. Die Lagerung der Klemmplatte als Schwenkteil an der Nut erfordert eine vergleichsweise breite Ausbildung des Verbindungselementes, was dessen Verwendung für Kleinschalter begrenzt und den Abstand zwischen benachbarten Verbindungselementen verkleinert. Ein weiterer Nachteil hinsichtlich der Baugrösse besteht darin, dass das Klemmelement nur ein im Prinzip abgewinkelter Bügel ist, der sich beim Festziehen der Klemmschrauben verformt und daher die Klemmkraft erniedrigt.Such a connecting element is known for example from EP-A-00 73 275. In this older connecting element, the body consists of a bracket, which has an abutment leg and a semicircular groove and a center piece, the groove being formed by a stump of the bracket. The mounting of the clamping plate as a swivel part on the groove requires a comparatively wide design of the connecting element, which limits its use for small switches and reduces the distance between adjacent connecting elements. Another disadvantage with regard to the size is that the clamping element is only an angled bracket in principle, which deforms when the clamping screws are tightened and therefore reduces the clamping force.

Die vorliegende Erfindung stellt sich daher die Aufgabe, ein Verbindungselement der eingangs genannten Art derart zu verbessern, dass bei kleineren äusseren Abmessungen mindestens gleich grosse Einspannkräfte erzeugt werden können, ohne dass dadurch die Bedienungsfreundlichkeit leidet.The object of the present invention is therefore to improve a connecting element of the type mentioned at the outset in such a way that, with smaller outer dimensions, at least the same clamping forces can be generated without thereby reducing the ease of use.

Erfindungsgemäss wird diese Aufgabe durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.According to the invention, this object is achieved by the characterizing features of claim 1.

Für das Anschliessen von zwei Leiterdrähten wird vorzugsweise die der ersterwähnten Innenfläche zugewandte Klemmfläche der Klemmplatte mit zwei konkaven Ausnehmungen zum teilweisen Umfassen der drahtförmigen Leiter versehen.For the connection of two conductor wires, the clamping surface of the clamping plate facing the first-mentioned inner surface is preferably provided with two concave recesses for partially enclosing the wire-shaped conductors.

Nach einem weiteren bevorzugten Ausführungsbeispiel ist vorgesehen, dass am oberen Ende des Verschiebeweges der Klemmplatte eine zur zweiten Innenfläche parallele Keilfläche angeordnet ist. Dadurch ist es möglich, die Klemmplatte beim Entspannen gleichzeitig von der ersterwähnten Fläche wegzuzwingen.According to a further preferred exemplary embodiment, it is provided that a wedge surface parallel to the second inner surface is arranged at the upper end of the displacement path of the clamping plate. This makes it possible to simultaneously force the clamping plate away from the first-mentioned surface when relaxing.

Anhand der beiliegenden schematischen Zeichnung wird die Erfindung beispielsweise erläutert. Es zeigen:

Fig. 1
einen Längsschnitt durch einen Anschluss entsprechend dem Schnitt I - I in Fig. 2 und
Fig. 2
einen Schnitt längs der Linie II - II in Fig. 1.
The invention is explained, for example, with the aid of the attached schematic drawing. Show it:
Fig. 1
a longitudinal section through a connection corresponding to the section I - I in Fig. 2 and
Fig. 2
a section along the line II - II in Fig. 1st

In der Zeichnung bezeichnet die Hinweisziffer 1 das rückseitige Ende des Gehäuses eines Schalt- und Meldegerätes, das mit Steckerstiften 2 für den Anschluss elektrischer Leiter versehen ist, wobei in der Zeichnung nur einer der Steckerstifte gezeigt ist. Der Steckerstift 2 endet in einem im Schaltergehäuse rückseitig liegenden Hohlraum 3 der nach hinten durch einen Deckel 1a abgeschlossen ist. Auf den Steckerstift 2 kann in an sich bekannter Weise eine mit einem elektrischen Leiter fest verbundene Buchse aufgesteckt werden, wobei im Deckel 1a für das Hindurchführen des Leiters eine zum Stecker 2 achsiale Oeffnung vorzusehen ist. Für den Anschluss eines keine Buchse aufweisenden Leiters 4 an den Steckerstift 2 ist eine Klemmverbindung vorgesehen. Hierzu ist der Steckerstift 2 von einem rahmenförmigen Körper 5 umgeben, der an einem Ende durch einen Boden 6 abgeschlossen und am anderen Ende offen ist. Eine Wand des Körpers 5 bildet eine gegen den Steckerstift 2 anliegende Innenfläche 7, der eine zweite, sie spitzwinklig schneidende Innenfläche 8 gegenüberliegt. Die beiden Innenflächen 7 und 8 schneiden sich unter einem Winkel von ca. 30o und konvergieren gegen den Boden 6 in dem eine Gewindebohrung 9 mit der Bohrungsachse 10 angeordnet ist. Die Bohrungsachse 10 bildet mit der Innenwand 7 einen Winkel von ca. 15o und liegt vorzugsweise auf der Winkelhalbierenden zwischen den beiden Fläche 7 und 8. In die Gewindebohrung 9 ist eine Schraube 11 geschraubt, deren Schaft anschliessend an den Schraubenkopf einen zylindrischen Hals 12 aufweist, an dem eine Klemmplatte 13 mit einer von der Schraube 11 durchsetzten Schlitzöffnung 14 unverlierbar gehalten ist. Die Klemmplatte 13 weist den beiden Innenflächen 7 und 9 zugewandte Klemmflächen 15 und 16 auf, wobei die Klemmfläche 16 mit zwei konkaven Ausnehmungen für das teilweise Umfassen eines elektrischen Leiters 4 aufweist. Befindet sich die Klemmplatte 13 in der in Fig. 1 gezeigten äusseren Lage, wird die Schraube 11 in Fig. 2 im Uhrzeigersinn gedreht, verschiebt sie die Klemmplatte 13 gegen den Boden 6, wobei die Klemmfläche 15 entlang der Innenfläche 8 gleitet und dadurch gegen die Innenfläche 7 geschoben wird. Mit zunehmendem Eintauchen der Klemmplatte 13 werden die in den Ausnehmungen 17 liegenden elektrischen Leiter 4 gegen den Steckerstift 2 und dieser gegen die Innenfläche 7 gepresst wodurch der Körper 5 kraftschlüssig mit dem Steckerstift 2 verbunden wird. Der Steckerstift 2 wird somit zwischen den elektrischen Leitern 4 und der Innenfläche 7 eingeklemmt.In the drawing, reference number 1 denotes the rear end of the housing of a switching and signaling device which is provided with plug pins 2 for the connection of electrical conductors, only one of the plug pins being shown in the drawing. The plug pin 2 ends in a cavity 3 on the back of the switch housing, which is closed off at the rear by a cover 1a. In a manner known per se, a socket firmly connected to an electrical conductor can be plugged onto the plug pin 2, an opening that is axial to the plug 2 being provided in the cover 1a for the passage of the conductor. A clamp connection is provided for connecting a conductor 4 which does not have a socket to the plug pin 2. For this purpose, the plug pin 2 is surrounded by a frame-shaped body 5, which at one end closed by a bottom 6 and open at the other end. A wall of the body 5 forms an inner surface 7 which bears against the plug pin 2 and which is opposite a second inner surface 8 which intersects it at an acute angle. The two inner surfaces 7 and 8 intersect at an angle of approximately 30 ° and converge towards the bottom 6 in which a threaded bore 9 with the bore axis 10 is arranged. The bore axis 10 forms with the inner wall 7 by an angle of approximately 15 o, and preferably on the bisecting line between the two surface 7 and 8. In the threaded hole 9, a screw 11 is screwed whose shank has adjoining the screw head a cylindrical neck 12 , on which a clamping plate 13 with a slot opening 14 penetrated by the screw 11 is held captive. The clamping plate 13 has the two inner surfaces 7 and 9 facing clamping surfaces 15 and 16, the clamping surface 16 having two concave recesses for partially enclosing an electrical conductor 4. If the clamping plate 13 is in the outer position shown in Fig. 1, the screw 11 is rotated clockwise in Fig. 2, it moves the clamping plate 13 against the bottom 6, the clamping surface 15 sliding along the inner surface 8 and thereby against the Inner surface 7 is pushed. With increasing immersion of the clamping plate 13, the recesses 17 lying electrical conductor 4 against the plug pin 2 and this is pressed against the inner surface 7, whereby the body 5 is non-positively connected to the plug pin 2. The plug pin 2 is thus clamped between the electrical conductors 4 and the inner surface 7.

Damit die in Folge der Schlitzöffnung 14 mit Spiel auf der Schraube 11 sitzende Klemmplatte 13 beim Herausdrehen der Schraube 11 (in Fig. 2: Drehen im Gegenuhrzeigersinn) von den elektrischen Leitern 4 abgehoben wird, ist am Deckel 1a eine Nase 19 befestigt, die am freien Ende mit einer zur Innenfläche 8 parallelen Keilfläche 20 versehen ist. Sobald die Klemmplatte 13 auf die Keilfläche 20 auftrifft, wird sie gegen die Innenfläche 8 verschoben und mit dieser in Berührungskontakt gehalten. Der mit dem Schaltergehäuse 1 verbundene Deckel 1a weist zwei Durchbrechungen 21 und 22 auf. Durch die Durchbrechung 21 ist die Schraube 11 von aussen zugänglich, wogegen durch die Durchbrechung 22 der elektrische Leiter in den Körper 5 gesteckt wenden kann.So that as a result of the slot opening 14 with play on the screw 11, the clamping plate 13 is lifted off the electrical conductors 4 when the screw 11 is unscrewed (in FIG. 2: turning counterclockwise), a lug 19 is attached to the cover 1a, which on free end is provided with a wedge surface 20 parallel to the inner surface 8. As soon as the clamping plate 13 strikes the wedge surface 20, it is displaced against the inner surface 8 and held in contact therewith. The cover 1a connected to the switch housing 1 has two openings 21 and 22. Through the opening 21, the screw 11 is accessible from the outside, whereas the electrical conductor can turn through the opening 22 inserted into the body 5.

Ist das Befehls- oder Meldegerät für eine Steckverbindung vorzusehen, wird der Deckel 1a ausgewechselt und der Körper 5 vom Steckerstift 2 abgezogen und entfernt. Umgekehrt ist das Befehls- oder Meldegerät mit einer Klemmanschlussmöglichkeit zu versehen, wird ein Deckel 1a mit den Durchbrechungen 21 und 22 gewählt und ein Körper 5 über den Steckerstift 2 geschoben. Nach einem nicht dargestellten Ausführungsbeispiel kann die Nase 19 mit der Keilfläche 20 anstatt mit dem Deckel 1a mit dem Körper 5 verbunden sein.If the command or signaling device is to be provided for a plug connection, the cover 1 a is replaced and the body 5 is removed from the plug pin 2 and removed. Conversely, the command or signaling device is to be provided with a terminal connection option, a cover 1a with the openings 21 and 22 is selected and a body 5 is pushed over the plug pin 2. To In one embodiment, not shown, the nose 19 can be connected to the body 5 with the wedge surface 20 instead of with the cover 1a.

Weiter kann die Klemmplatte durch Formschluss mit Teilen des Körpers 5 gegen ein Mitdrehen mit der Schraube 11 gesichert sein.Furthermore, the clamping plate can be secured by positive locking with parts of the body 5 against turning with the screw 11.
