Description

Die Erfindung bezieht sich auf eine Anschlußklemme zur leitenden Verbindung von elektrischen Leitungen miteinander oder mit Schaltgeräten, wobei die zu verbindenden Teile eines in ein Gehäuse eingesetzten Klemmstückes und eine dieses verspannende Klemmschraube festklemmbar sind.The invention relates to a connecting terminal for the conductive connection of electrical lines to one another or to switching devices, the parts to be connected of a clamping piece inserted into a housing and a clamping screw bracing it being clampable.

Bei Anschlußklemmen dieser Art, wie auch bei Lüsterklemmen, ist die anzuschließende Leitung vor dem Anziehen der Klemmschraube achssenkrecht zu dieser zwischen die Klemmscheibe und ein ortsfestes Gegenlager bzw. eine Büchse einzuführen. Das Verdrahten von beispielsweise in Schalttafeln dicht nebeneinander angeordneter Geräte, wie Tastern und dgl., ist auf diese Weise jedoch mit großen Schwierigkeiten verbunden, da ein ausreichender Arbeitsraum nicht zur Verfügung steht und eine gute Übersichtlichkeit nicht gegeben ist. Außer einer großen Geschicklichkeit, um das meist abgewinkelte Ende der Leitung einzufädeln, erfordert das Einführen der anzuschließenden Leitungen somit mitunter oftmals auch einen verhältnismäßig großen Zeitaufwand, durch den die Montage verteuert wird.In connection terminals of this type, as also in the case of luster terminals, the line to be connected is to be inserted axially perpendicular to the latter between the clamping disk and a stationary counter bearing or a bushing before tightening the clamping screw. The wiring of devices, such as buttons and the like, which are arranged closely next to one another, for example, in control panels, is associated with great difficulties in this way, since an adequate work space is not available and there is no good clarity. In addition to great skill to thread the mostly angled end of the line, the insertion of the lines to be connected often requires a relatively large amount of time, which makes the assembly more expensive.

Eine Anschlußklemme der vorgenannten Art für eine mit einem ortsfesten Anschlußteil zu verbindenden Leitung ist durch die US-A-4 175 822 bekannt. Bei dieser Ausgestaltung ist das Klemmstück lose in einem Gehäuse gehalten und erst durch Anziehen der Klemmschraube, die auf dieses drückt, wird es in Richtung der anzuschließenden Leitung gezogen. Das mit einer Ausnehmung versehene Klemmstück nimmt hierbei den ortsfesten Anschlußteil sowie die anzu-schließende Leitung auf. Da das Klemmstück ohne exakte Führung in dem Gehäuse gehalten und nicht mit der Klemmschraube fest verbunden ist, wird dieses beim Lösen einer Verbindung auch nicht selbsttätig in die Ausgangslage zurückgeführt; das Klemmstück kann somit mitunter eine derartige Stellung einnehmen, daß das Einführen einer Litze erschwert oder u. U. nicht möglich ist.A connector of the aforementioned type for a line to be connected to a stationary connector is known from US-A-4 175 822. In this embodiment, the clamping piece is held loosely in a housing and it is only by tightening the clamping screw that presses it that it is pulled in the direction of the line to be connected. The clamping piece provided with a recess accommodates the fixed connection part and the line to be connected. Since the clamping piece is held in the housing without exact guidance and is not firmly connected to the clamping screw, this is not automatically returned to the starting position when a connection is released; the clamping piece can thus sometimes occupy such a position that the insertion of a stranded wire difficult or u. May not be possible.

Es ist daher Aufgabe der Erfindung, eine Anschlußklemme der vorgenannten Gattung zu schaffen, mittels der die anzuschließende Leitung auf einfache Art und Weise leicht eingeführt und festgeklemmt werden kann und diese nicht achssenkrecht zur Klemmschraube, sondern nahezu achsparallel zu dieser einzuführen ist, so daß bei guter Übersichtlichkeit eine Verdrahtung in kurzer Zeit und ohne Schwierigkeiten vorzunehmen ist.It is therefore an object of the invention to provide a terminal of the aforementioned type, by means of which the line to be connected can be easily inserted and clamped in a simple manner and this is not to be introduced perpendicular to the clamping screw, but rather almost parallel to it, so that with good For clarity, wiring can be carried out in a short time and without difficulty.

Gemäß der Erfindung wird dies dadurch erreicht, daß das Klemmstück als ein einen Anlageschenkel, ein Mittelstück und einen gegen das Mittelstück gebogenen Klemmschenkel aufweisendes Halteglied ausgebildet ist, wobei der Anlageschenkel mit dem Mittelstück einstückig, nahezu L-förmig ausgebildet ist und dieses sowie der Klemmschenkel von der Klemmschraube durchsetzt sind, wobei der Mittelschenkel einen Schraubkanal für die Klemmschraube aufweist, mittels der der Klemmschenkel mit Sperrhakenwirkung für die Anschluß-leitung gegen den sich an dem Gehäuse abstützenden Anlageschenkel oder ein mit diesem zusammenwirkendes Verbindungsglied preßbar ist.According to the invention, this is achieved in that the clamping piece is designed as a holding member having a contact leg, a central piece and a clamping leg bent against the central piece, the contact leg being formed in one piece with the central piece, almost L-shaped, and this and the clamping leg of the clamping screw are penetrated, the middle leg having a screw channel for the clamping screw, by means of which the clamping leg with a locking hook effect for the connecting line can be pressed against the abutting leg on the housing or a connecting element interacting with it.

Der Anlageschenkel sollte hierbei parallel zu dem Schraubkanal verlaufend oder geringfügig zu diesem nach außen geneigt in Richtung der anzuschließenden Leitung von dem Mittelstück des Klemmstückes abstehen, so daß die Leitung leicht einzuführen ist.The contact leg should run parallel to the screw channel or slightly inclined to the outside in the direction of the line to be connected from the center piece of the clamping piece, so that the line is easy to insert.

Zweckmäßig ist es des weiteren, den Klemmschenkel mit einer langlochartig ausgebildeten Ausnehmung zu versehen, in der die Klemmschraube drehbar und axial unverschiebbar, somit also unverlierbar gehalten ist. Dies ist in der Weise zu bewerkstelligen, indem die Klemmschraube mit einem gegenüber dem Gewindeteil abgesetzten Bereich ausgestattet wird, mittels dem diese in der länglochartigen nach deren Einführen verformten Ausnehmung des Klemmschenkels gehalten ist.It is furthermore expedient to provide the clamping leg with a slot-shaped recess in which the clamping screw is rotatably and axially immovable, and thus is held captive. This can be accomplished in that the clamping screw is equipped with an area that is offset from the threaded part, by means of which it is held in the elongated hole-like recess of the clamping leg deformed after its insertion.

Der Klemmschenkel kann mit einem vorzugsweise ballig ausgebildeten Ende verschwenkbar in einer in das Mittelstück eingeformten Nut gehalten sein, dieser kann aber auch unmittelbar an dem dem Anlageschenkel gegenüberliegenden Ende des Mittelstückes an diesem angeformt werden, so daß das Führungs-und Halteglied aus einem Stück gepreßt oder gestanzt werden kann.The clamping leg can be pivotably held in a groove formed in the middle piece with a preferably spherical end, but this can also be molded directly onto the end of the middle piece opposite the contact leg, so that the guide and holding member is pressed from one piece or can be punched.

Nach einer vorteilhaften Weiterbildung ist zur Verspannung von unterschiedlich stark bemessener Anschlußleitungen vorgesehen, an dem Anlageschenkel des Klemmstückes oder an dem an diesem anliegenden Verbindungsglied ein sich in Längsrichtung erstreckendes Kipplager anzubringen, so daß das Verbindungsglied indifferent abgestützt ist und sich somit um die Längsachse jeweils bis zur Anlage an den Leitungen beweglich ist.According to an advantageous development is provided for bracing differently dimensioned connecting lines to attach a longitudinally extending tilting bearing on the contact leg of the clamping piece or on the connecting member adjacent to it, so that the connecting member is supported indifferently and thus around the longitudinal axis in each case up to System on the lines is movable.

Das Kipplager kann durch einen auf der dem Klemmschenkel zugekehrten Seite des Anlageschenkels angeformten, sich in Längsrichtung erstreckenden und vorzugsweise mittig angeordneten Nocken gebildet sein, an dem das Verbindungsglied abgestützt ist, oder in ähnlicher Weise durch einen auf der dem Anlageschenkel zugekehrten Seite des Verbindungsgliedes angeformten, sich in Längsrichtung erstreckenden und vorzugsweise mittig angeordneten Nocken, über den das Verbindungsglied an dem Anlageschenkel abgestützt ist, wobei der an dem Anlageschenkel oder dem Verbindungsglied angeformte Nocken konvex gekrümmt oder im Querschnitt dreieckförmig ausgebildet sein sollte.The tilting bearing can be formed by a cam formed on the side of the contact leg facing the clamping leg, which extends in the longitudinal direction and is preferably arranged centrally, on which the connecting member is supported, or in a similar manner by a molded on the side of the connecting member facing the contact leg. extending in the longitudinal direction and preferably centrally arranged cams, via which the connecting member is supported on the contact leg, the cam formed on the contact leg or the connecting member should be convexly curved or triangular in cross section.

Angebracht ist es ferner, den Anlageschenkel oder das Verbindungsglied auf der den anzuschließenden Leitungen zugekehrten Seite jeweils mit einem oder mehreren senkrecht oder geneigt zu deren Längsachse verlaufenden Vorsprüngen zu versehen, so daß stets eine gute Verklemmung gewährleistet ist.It is also appropriate to provide the contact leg or the connecting member on the side facing the lines to be connected with one or more projections running perpendicularly or inclined to their longitudinal axis, so that a good one is always provided Jamming is guaranteed.

Die gemäß der Erfindung ausgebildete Anschlußklemme ist nicht nur einfach in der konstruktiven Ausgestaltung und damit auf wirtschaftliche Weise herzustellen, sondern diese ermöglicht auch eine einfache Handhabung und erlaubt es, eine oder mehrere Leitungen in kurzer Zeit sicher anzu-schließen. Wird nämlich das Klemmstück als ein einen Anlageschenkel, ein Mittelstück und einen gegen das Mittelstück gebogenen Klemmschenkel aufweisendes Halteglied ausgebildet, ist es möglich, die anzuschließende Leitung nahezu achsparallel zu der in dem Mittelstück gehaltenen Klemmschraube einzuführen und auf einfach Weise durch Anziehen der Klemmschraube festzuklemmen.The connecting terminal designed in accordance with the invention is not only simple in terms of construction and thus economical to manufacture, but it also enables simple handling and allows one or more lines to be securely connected in a short time. If the clamping piece is designed as a holding member having a contact leg, a middle piece and a holding member bent against the middle piece, it is possible to insert the line to be connected almost axially parallel to the clamping screw held in the middle piece and to clamp it in a simple manner by tightening the clamping screw.

An einem mit einer solchen Anschlußklemme ausgestatteten Gerät stehen somit keine Leitungen seitlich ab, diese verlaufen vielmehr achsparallel zu diesem, so daß Geräte äußerst dicht nebeneinander angeordnet werden können. Die Verdrahtung ist aber dennoch, zumal die Anschlüsse gut zu übersehen sind, leicht und in kurzer Zeit vorzunehmen. Außerdem ist die gemäß der Erfindung ausgebildete Anschlußklemme nicht nur für alle Leiterarten, sondern auch, da der Verstellbereich des Klemmschenkels groß gewählt werden kann und der Anlageschenkel oder das Verbindungsglied in Längsrichtung kippbar abgestützt sein können, ohne bauliche Abänderungen auch für unterschiedlich stark bemessene Leitungen verwendbar.No lines protrude laterally from a device equipped with such a connecting terminal, but rather run axially parallel to it, so that devices can be arranged extremely close to one another. However, the wiring is easy and quick, especially since the connections are easy to miss. In addition, the terminal designed according to the invention is not only suitable for all types of conductors, but also because the adjustment range of the clamping leg can be chosen to be large and the contact leg or the connecting member can be tiltably supported in the longitudinal direction, without structural modifications, even for lines of different dimensions.

In der Zeichnung sind Ausführungsbeispiele der gemäß der Erfindung ausgebildeten Anschlußklemme dargestellt und nachfolgend im einzelnen erläutert. Hierbei zeigen, jeweils im Schnitt:

  • Fig. 4 einen Schnitt nach der Linie IV - IV der Fig. 3.
In the drawing, exemplary embodiments of the connecting terminal designed according to the invention are shown and explained in detail below. Here, each in section:
  • 1 shows the connecting terminal with a three-part clamping piece used in a housing for bracing the line to be connected, the clamping leg being connected in an articulated manner to the central piece of the clamping piece,
  • 1 with a clamping piece whose clamping leg is integrally formed on the central part,
  • Fig. 3 is a connector equipped with a tiltably supported connector according to Fig. 1 and
  • 4 shows a section along the line IV - IV of FIG. 3rd

Die in den Fig. 1 und 2 dargestellte und mit 1 bezeichnete Anschlußklemme besteht aus einem dreiteiligen, in einem Gehäuse 2 eingesetzten Klemmstück 11 bzw. 11' und einer Klemmschraube 21, mittels der die in die Einführöffnung 3 des Gehäuses 2 eingesteckte, mit der Leitung 5 zu verbindende Leitung 4 festgeklemmt werden kann. Dazu ist in einem Mittelstück 12 des Klemmstückes 11 bzw. 11' ein Schraubkanal 13 für die Klemmschraube 21 eingearbeitet und an dem einen Ende des Mittelstückes 12 ist ein sich achsparallel zu dieser erstreckender Anlageschenkel 14 angeformt, am anderen Ende ist dagegen ein Klemmschenkel bzw. 15' angelenkt.1 and 2 and designated 1 consists of a three-part, in a housing 2 inserted clamping piece 11 and 11 'and a clamping screw 21, by means of which the inserted into the insertion opening 3 of the housing 2 with the line 5 line 4 to be connected can be clamped. For this purpose, a screw channel 13 for the clamping screw 21 is incorporated in a central piece 12 of the clamping piece 11 or 11 'and an abutment leg 14 extending axially parallel to it is formed on one end of the central piece 12, while on the other end there is a clamping leg or 15 'articulated.

Gemäß Fig. 1 ist dazu das Mittelstück 12 mit einer halbreisförmigen Nut 18 versehen und das in diese eingreifende nde 19 des Klemmschenkels 15 ist ballig ausgebildet, nach Fig. 2 ist der Klemmschenkel 15' unmittelbar an dem Mittelstück 12 angeformt. In den Klemmschenkel 15 bzw. 15' ist eine langlochartige Ausnehmung 16 eingearbeitet, deren Breite geringfügig größer bemessen ist als der gewindefreie Bereich 23 der Klemmschraube 21, so daß diese mittels des Schraubenkopfes und des Gewindeabschnittes 22 zwar drehbar aber axial unverschiebbar und somit unverlierbar in dem Klemmschenkel 15 bzw. 15' gehalten ist. Der Klemmschenkel 15 bzw. 15' wird, um dies zu bewerkstelligen, nach dem Einführen der Klemmschraube 21 in die Ausnehmung 16 geringfügig zusammengepreßt.According to FIG. 1, the middle piece 12 is provided with a semi-circular groove 18 and the end 19 of the clamping leg 15 engaging in this is spherical, according to FIG. 2 the clamping leg 15 'is formed directly on the middle piece 12. In the clamping leg 15 and 15 'a slot-like recess 16 is incorporated, the width of which is dimensioned slightly larger than the unthreaded area 23 of the clamping screw 21, so that it can be rotated by means of the screw head and the threaded portion 22 but axially immovable and therefore captive in the Clamp leg 15 or 15 'is held. To accomplish this, the clamping leg 15 or 15 'is slightly compressed after inserting the clamping screw 21 into the recess 16.

Zur leitenden Verbindung der Leitung 4 mit der Leitung 5 ist, nachdem die Leitung 4 in die achsparallel zur Klemmschraube 21 sich erstreckende Öffnung 3 eingeführt ist, lediglich die Klemmschraube 21 mit Hilfe eines durch eine Öffnung 6 des Gehäuses 2 einzuführenden Werkzeuges zu verdrehen. Dadurch wird der Klemmschenkel 15 bzw. 15' mit der Anlagefläche 17 gegen das Ende der Leitung 4 und diese gegen den Anlageschenkel 14 gepreßt, so daß, da an diesen die Leitung 5 angeschlossen ist, beide Leitungen miteinander verbunden sind. Die langlochartige Ausnehmung 16 ermöglicht dabei einen großen Verschwenkbereich des Klemmschenkels 15 bzw. 15', die Anschlußklemme 1 kann daher auch, ohne daß bauliche Veränderungen vorzunehmen sind, für unterschiedlich stark bemessene Leitungen verwendet werden. Auch ist deren Anschluß jeweils auf einfache Weise und in kurzer Zeit vorzunehmen, da diese achsparallel zur Klemmschraube 21 in das Gehäuse 2 einzuführen sind.For the conductive connection of the line 4 to the line 5, after the line 4 is inserted into the opening 3 which extends axially parallel to the clamping screw 21, only the clamping screw 21 is to be rotated with the aid of a tool to be inserted through an opening 6 in the housing 2. Characterized the clamping leg 15 and 15 'with the contact surface 17 against the end of the line 4 and this is pressed against the contact leg 14, so that since the line 5 is connected to both lines are connected to each other. The slot-like recess 16 enables a large swiveling range of the clamping leg 15 or 15 ', the connecting terminal 1 can therefore also be used for lines of different dimensions without having to make any structural changes. Also, their connection is to be carried out in a simple manner and in a short time, since these are to be inserted into the housing 2 parallel to the clamping screw 21.

Bei der Anschlußklemme 31 nach den Fig. 3 und 4 ist in einem Gehäuse 32 wiederum ein Klemmstück 41 eingesetzt, mittels dem im Durchmesser unterschiedlich stark bemessene Leitungen 35 und 36 mit einem ebenfalls in dem Gehäuse 32 angeordneten Verbindungsglied 34 elektrisch leitend sicher zu verbinden sind. Dazu ist der von dem Mittelstück 42 des Klemmstückes 41 abstehende geringfügig nach außen geneigt verlaufende Anlageschenkel 44 mit einem sich in dessen Längsrichtung erstreckenden Kipplager 61 ausgestattet, so daß das an diesem abgestützte Verbindungsglied 34 indifferent gehalten ist.3 and 4, a clamping piece 41 is in turn inserted in a housing 32, by means of which lines 35 and 36 of different dimensions in diameter can be connected in an electrically conductive manner to a connecting member 34 likewise arranged in the housing 32. For this purpose, the projecting from the center piece 42 of the clamping piece 41 slightly outwardly inclined bearing leg 44 is equipped with a longitudinally extending tilting bearing 61 so that the connecting member 34 supported thereon is held indifferently.

Wird mit Hilfe der in einen Schraubkanal 43 des Mittelstückes 42 eingeschraubten Klemmsschraube 51 der Klemmschenkel 45 des Klemmstückes 41 mit seiner Anlagefläche 47 gegen die in die Öffnung 33 des hierbei zweiteilig ausgebildeten Gehäuses 32 eingeführten Leitungen 35 und 36 ge-preßt, so wird das Verbindungsglied 34 um das mittig an dem Anlageschenkel 44 angeordnete Kipplager 61 kippen. Die An-preßkraft wird somit auf beide Leitungen 35 und 36 übertragen, so daß auch beiden Leitungen zwischen dem Verbindungsglied 34 und dem Klemmschenkel 45 eingeklemmt sind.If, with the aid of the clamping screw 51 screwed into a screw channel 43 of the middle piece 42, the clamping leg 45 of the clamping piece 41 with its contact surface 47 is pressed against the lines 35 and 36 inserted into the opening 33 of the housing 32, which is formed here in two parts, then the connecting member 34 tilt around the tilting bearing 61 arranged centrally on the contact leg 44. The contact pressure is thus on both Lines 35 and 36 are transmitted so that both lines are clamped between the connecting member 34 and the clamping leg 45.

Das Kipplager 61 ist bei dem gezeigten Ausführungsbeispiel als konvex gekrümmter Nocken 62 ausgebildet, es kann aber auch im Querschnitt dreiecksförmig gestaltet oder an dem Verbindungsglied 34 angebracht werden. Außerdem sind an diesem senkrecht zur Längsachse verlaufende Vorsprünge 63 angeformt, die sich in die Leitungen 35 und 36 eindrücken, so daß stets eine sichere Verbindung gewährleistet ist.In the exemplary embodiment shown, the tilting bearing 61 is designed as a convexly curved cam 62, but it can also have a triangular cross section or can be attached to the connecting member 34. In addition, projections 63 which are perpendicular to the longitudinal axis and are pressed into the lines 35 and 36, so that a secure connection is always guaranteed.

Die Klemmschraube 51 ist in einem in den Klemmschenkel 45 eingearbeitetes Langloch 46 verdrehbar aber unverlierbar gehalten. Dazu ist an dieser zwischen dem Schraubenkopf und dem Gewindeteil 52 ein abgesetzter Bereich 53 vorgesehen, auf dessen Durchmesser der Klemmschenkel 45 nach dem Einführen der Klemmschraube 51 zusammengepreßt ist.
