Abstract

The multiple terminal block (1) has wire trapping spaces (2) which adjoin at each end face and serve for lateral passing through of conductors (3) or wire bundles (3'). These wire trapping spaces (2) form a pivot point for the terminal block (1) which is rotatable in its longitudinal extent, the wire bundle (3') acting as a pivot axis in the wire trapping space (2). In this way, such terminal blocks can be moved easily on the distribution frame between assembly position and readily accessible manipulation position without substantially stressing the conductors and their connection points. <IMAGE>

Description

Die vorliegende Erfindung betrifft eine Mehrfach-Anschluss­leiste für deren Anordnung an parallelen Vertikalträgern von Schwachstrom-Verteileranlagen.The present invention relates to a multiple terminal block for its arrangement on parallel vertical supports of low-voltage distribution systems.

Mehrfach-Anschlussleisten der vorgenannten Art befinden sich in der Regel vielzahlig und in dichter Anordnung an den Ver­tikalträgern der Gestell-Systeme von Telefonanlagen u. dgl. und dienen der Verbindung der ankommenden und abgehenden Lei­ter.Multiple terminal strips of the aforementioned type are usually numerous and in close arrangement on the vertical supports of the frame systems of telephone systems and. Like. And serve the connection of the incoming and outgoing conductor.

Problematisch ist dabei die Unzugänglichkeit der am Gestell angeordneten Anschlussleisten, zu denen eine grosse Anzahl, in der Regel zu Drahtbündeln zusammengefasste Leiter führen, welche das Wegnehmen resp. Wiedermontieren der Anschlusslei­sten erschweren und welche mit grossen Reserven verlegt sein müssen, um überhaupt einen genügend grossen Arbeitsabstand mit den Anschlussleisten erreichen zu können, wenn an diesen etwa für Aenderungen, Ergänzungen, Kontrollen u. dgl. zu ar­beiten ist. Hierfür werden die Anschlussleisten vom Gestell demontiert, unter Streckung der Drahtbündel weit nach vorn ge­zogen und um ihre Längsachse gedreht, um die hinteren An­schlussmittel nach vorn zu bringen und zugänglich zu machen. Dabei werden die Drahtbündel und Einzelleiter unkontrollierten Bewegungen und Belastungen ausgesetzt und nehmen insbesondere beim Zurücksetzen der betreffenden Anschlussleisten undefinier­te Lagen ein, was sich an den Verbindungsstellen negativ aus­wirkt.The problem is the inaccessibility of the connection strips arranged on the frame, to which a large number, usually lead to bundles of wires, which remove or. Difficult to reassemble the terminal strips and which must be installed with large reserves in order to be able to achieve a sufficiently large working distance with the terminal strips when they are used for changes, additions, checks and the like. Like. is to work. For this purpose, the connection strips are removed from the frame, pulled far forward while stretching the wire bundle and rotated about their longitudinal axis in order to bring the rear connection means forward and to make them accessible. The wire bundles and individual conductors are exposed to uncontrolled movements and loads and assume undefined positions, in particular when resetting the relevant terminal strips, which has a negative effect on the connection points.

Aufgabe der Erfindung ist es nun, die Mehrfach-Anschlusslei­sten für deren Anordnung an parallelen Vertikalträgern von Schwachstrom-Verteileranlagen so auszubilden, dass sich diese leicht zwischen Montagelage und gut zugänglicher Manipulations­lage bewegen lassen ohne wesentliche Beanspruchung der Leiter und deren Verbindungsstellen.The object of the invention is now to design the multiple terminal strips for their arrangement on parallel vertical supports of low-voltage distribution systems in such a way that they can be easily moved between the mounting position and the easily accessible manipulation position without significant stress on the conductors and their connection points.

Dies wird erfindungsgemäss dadurch erreicht, dass sich an je­der Stirnseite der Anschlussleiste ein Drahtfangraum zur seit­lichen Hindurchführung von Leitern resp. Drahtbündeln an­ schliesst, welcher Drahtfangraum einen Drehpunkt für die in ihrer Längserstreckung drehbare Anschlussleiste bildet und in dem das Drahtbündel als Drehachse wirksam ist.This is achieved according to the invention in that a wire trap space for the lateral passage of conductors or. Bundles of wires closes which wire-catching space forms a fulcrum for the terminal strip, which can be rotated in its longitudinal extent, and in which the wire bundle acts as an axis of rotation.

Eine derart an den Drahtbündeln quasi aufgehängte Anschluss­leiste lässt sich, etwa vom Verteilergestell nach vorn gezo­gen, leicht um die als Drehachsen wirksamen Drahtbündel ver­drehen, wobei sich die Drahtbündel im Drahtfangraum frei ver­schieben, so dass sich nur der Einlaufbogen der Drahtbündel in den Drahtfangraum etwas öffnet oder schliesst, was bei ge­nügend grossem Bogenradius völlig unkritisch ist.Such a terminal strip, which is quasi suspended from the wire bundles, can be easily rotated around the wire bundles that act as axes of rotation, for example, pulled forward from the distribution frame, the wire bundles freely moving in the wire trapping space, so that only the inlet bend of the wire bundles opens or opens somewhat in the wire trapping space closes what is completely uncritical if the arc radius is large enough.

Eine bevorzugte Ausführungsform einer solchen Anschlussleiste kann dann darin gesehen werden, dass an jeder Stirnseite an­geflanschte Laschen den Drahtfangraum als äussere Seitenwand begrenzen, wobei dann die Laschen zwischen sich einen Einfä­delschlitz für die Leiter begrenzen.A preferred embodiment of such a terminal strip can then be seen in that tabs flanged on each end face delimit the wire catching space as an outer side wall, the tabs then delimiting a threading slot for the conductors between them.

Diese Massnahmen gestatten neben einer baulich übersichtlichen Ausgestaltung ein einfaches Einbringen der Leiter in den Drahtfangraum.In addition to a structurally clear design, these measures allow the conductors to be simply inserted into the wire catching space.

Wird weiter vorgesehen, dass die stirnseitig an der Anschluss­leiste ausgebildeten inneren Seitenwände der Drahtfangräume wenigstens teilweise elastische Zungen sind, die zum Zusammen­wirken mit Ausnehmungen in den Vertikalträgern des Verteiler­ gestelles bestimmte Klinken tragen, können die Anschlusslei­sten im Schnappverschlussverfahren montiert resp. demontiert werden.It is further provided that the inner side walls of the wire trapping spaces formed on the end face of the terminal strip are at least partially elastic tongues that interact with recesses in the vertical supports of the distributor certain pawls, the terminal strips can be snap-fitted or be dismantled.

Eine beispielsweise Ausführungsform des Erfindungsgegenstan­des ist nachfolgend anhand der Zeichnung näher erläutert.An example embodiment of the subject matter of the invention is explained in more detail below with reference to the drawing.

Es zeigen:

  • Fig. 1 in schaubildartiger Darstellung in Teilansicht einen Vertikalträger einer Schwachstrom-Verteileranlage mit einigen erfindungsgemässen Mehrfach-Anschlussleisten in unterschiedlichen Lager zum Träger; und
  • Fig. 2 in schaubildartiger Darstellung eine Teilansicht ei­ner Anschlussleiste gemäss Fig. 1, in grösserem Mass­stab.
Show it:
  • 1 is a diagrammatic illustration in partial view of a vertical support of a low-current distribution system with some multiple connection strips according to the invention in different bearings for the support; and
  • Fig. 2 in a diagram-like representation a partial view of a terminal block according to FIG. 1, on a larger scale.

Fig. 1 zeigt einen Vertikalträger 10 mit Seitenplatinen 11 und 11′ eines Gestelles einer nicht näher dargestellten Schwachstrom-Verteileranlage, insbesondere Telefonanlage, an welchen Vertikalträger 10 eine Mehrzahl Mehrfach-Anschluss­leisten 1 übereinander angeordnet werden, um in bekannter Wei­se ankommende und abgehende Leiter 3 miteinander zu verbinden.Fig. 1 shows a vertical support 10 with side boards 11 and 11 'of a frame of a low-voltage distribution system, not shown, in particular telephone system, to which vertical support 10 a plurality of multiple terminal strips 1 are arranged one above the other, in a known manner incoming and outgoing conductors 3 with each other connect to.

Solche Verteilergestelle sind ansich bekannt und bedürfen hier somit keiner näheren Erläuterung.Such distribution racks are known per se and require them therefore no further explanation here.

Das hier vorliegende Problem befasst sich mit der spezifi­schen Ausgestaltung der Anschlussleisten 1, um diese leicht zwischen der in Fig. 1a gezeigten Montagelage und einer gut zugänglichen, in Fig. 1b resp. Fig. 1c dargestellten Manipu­lationslage bewegen zu können, ohne dabei die Leiter 3 und deren Verbindungsstellen an den Anschlussleisten spürbar zu beanspruchen.The problem here is concerned with the specific design of the connection strips 1, in order to easily connect them between the mounting position shown in FIG. 1a and an easily accessible one shown in FIG. Fig. 1c manipulation position to be able to move without noticeably stressing the conductor 3 and their connection points on the terminal strips.

Hierfür weist, wie insbesondere auch Fig. 2 veranschaulicht, jede Stirnseite einer Anschlussleiste 1 einen sich anschlies­senden Drahtfangraum 2 auf, welcher der seitlichen Hindurch­führung der Leiter 3 resp. eines Drahtbündels 3′ dient, wobei dieser Drahtfangraum 2 einen Drehpunkt für die in ihre Längs­erstreckung drehbare Anschlussleiste 1 bildet und das Draht­bündel 3′ im Drahtfangraum 2 als Drehachse wirkt.For this purpose, as also shown in FIG. 2 in particular, each end face of a terminal block 1 has an adjoining wire trap space 2, which leads the conductors 3 and. a wire bundle 3 'is used, this wire catcher 2 forms a fulcrum for the rotatable in its longitudinal extension terminal block 1 and the wire bundle 3' in the wire catcher 2 acts as an axis of rotation.

Wie eingangs erwähnt, wird zunächst die Anschlussleiste 1 vom Vertikalträger 10 gelöst (Fig. 1a), dann nach vorn gezo­gen (Fig. 1b) und dann gedreht, um die hinteren Anschlüsse der Anschlussleiste resp. die Ueberspannungsschutz-Kassette 12 zugänglich zu machen. Hierbei verschiebt sich das Drahtbün­del 3′ frei im Drahtfangraum 2, so dass sich nur der Einlauf­bogen 3˝ des Drahtbündels 3′ etwas öffnet oder schliesst, was sich bei genügend grossem Bogenradius nicht auf die Leiter­ anschlüsse auswirkt.As mentioned at the beginning, the terminal block 1 is first detached from the vertical support 10 (FIG. 1a), then pulled forward (FIG. 1b) and then rotated to the rear connections of the terminal block or. to make the overvoltage protection cassette 12 accessible. Here, the wire bundle 3 'moves freely in the wire catcher 2, so that only the inlet bend 3˝ of the wire bundle 3' opens or closes something, which does not affect the conductors with a sufficiently large arc radius connections affects.

Der Drahtfangraum 2 wird hier stirnseitig an der Anschluss­leiste 1 durch eine innere Seitenwand 6 und durch eine äusse­re Seitenwand 4,4′ begrenzt, wobei letztere durch angeflansch­te resp. angeformte Laschen gebildet ist. Diese Laschen 4 und 4′ begrenzen zudem einen Einfädelschlitz 5 für die Leiter 3.The wire trap space 2 is delimited here on the end face of the terminal block 1 by an inner side wall 6 and by an outer side wall 4, 4 ', the latter by flanged or. molded tabs is formed. These tabs 4 and 4 'also limit a threading slot 5 for the conductor 3rd

Um ferner die Anschlussleisten 1 im Schnappverschlussverfahren am Vertikalträger 10 montieren zu können (Fig. 1a), bildet je­de innere Seitenwand 6 an der Anschlussleiste 1 eine elasti­sche, von Hand wegdrückbare Zunge, die eine zum Zusammenwirken mit Ausnehmungen 8 in den Seitenplatinen 11 resp. 11′ des Ver­tikalträgers 10 bestimmte Klinke 7 trägt.In order to also be able to mount the terminal strips 1 on the vertical support 10 using the snap-lock method (FIG. 1a), each inner side wall 6 on the terminal strip 1 forms an elastic tongue which can be pushed away by hand and which is designed to interact with recesses 8 in the side plates 11 and 11, respectively. 11 'of the vertical support 10 certain pawl 7 carries.

Aus dem Vorbeschriebenen und aus der Zeichnung ergibt sich so­mit eine Verteileranlage, deren Mehrfach-Anschlussleisten ver­gleichsweise dem bekannten Stand der Technik sich auf ein­fachste Weise zwischen Montagelage und gut zugänglicher Mani­pulationslage ohne Beanspruchung von Leiter und deren An­schlüsse bewegen lassen, was neben hoher Funktionssicherheit eine nunmehr nur noch geringe Montagezeit gewährleistet.From the above and from the drawing, there is thus a distribution system, the multiple connection strips of which, compared to the known state of the art, can be moved in the simplest way between the mounting position and the easily accessible manipulation position without stressing the conductor and its connections, which, in addition to high functional reliability, is now only possible short assembly time guaranteed.
