Description

Die Erfindung betrifft einen Leiteranschluß mit einer an mindestens einem Ende mit einer Rückbiegung versehenen Stromschiene und mindestens einem von mittleren Stromschienenbereich her auf die Rückbiegung aufschiebbaren, mit einem Klemmglied versehenen Klemmkörper zum Anschließen eines elektrischen Leiters.The invention relates to a conductor connection with a busbar provided with a back bend at at least one end and at least one clamping body which can be pushed onto the back bend from the middle busbar region and is provided with a clamping member for connecting an electrical conductor.

Ein derartiger Leiteranschluß, wie er insbesondere für Hochstromklemmen interessant ist, ist aus der DE-A-34 08 006 bekannt. Bei derartigen Leiteranschlüssen müssen häufig dickdrähtige Leiter angeschlossen werden, so daß es wesentlich ist, den Leiter frei auf die Stromschiene legen zu können und erst dann den Klemmkörper über die Stromschiene und den Leiter schieben zu können.Such a conductor connection, as it is particularly interesting for high-current terminals, is known from DE-A-34 08 006. In the case of such conductor connections, thick-wired conductors often have to be connected, so that it is essential to be able to lay the conductor freely on the conductor rail and only then to be able to push the clamp body over the conductor rail and the conductor.

Es ist ferner grundsätzlich bekannt, den Klemmkörper eines Schraubanschlusses in geführter Form zur Klemmstelle auf der Stromschiene über den aufgelegten Leiter zu verschieben. Entweder wird dabei der Klemmkörper mehr oder weniger lagegerecht auf der Stromschiene selbst ein wenig geführt (CH-A 392 658), oder es sind in komplizierter Weise durch entsprechende Gestaltung der elektrisch leitenden Teile selbst unter Einschluß besonderer Führungsstücke sowie Rasthalterungen Führungen für die Klemmkörper gebildet (DE-U 1 919 176).It is also fundamentally known to move the clamping body of a screw connection in a guided form to the clamping point on the conductor rail via the conductor placed on it. Either the clamp body is guided a little more or less in the correct position on the conductor rail itself (CH-A 392 658), or guides for the clamp body are formed in a complicated manner by appropriate design of the electrically conductive parts, including special guide pieces and latching brackets ( DE-U 1 919 176).

Bei Leiteranschlüssen mit Stromschienen der gattungsgemäßen Art sind derartige Führungsmöglichkeiten nicht gegeben, wobei hinzukommt, daß das Aufsetzen des Klemmkörpers auf die Rückbiegung vom mittleren Stromschienenbereich her schon von Haus aus erhebliches handwerkliches Geschick erfordert und insbesondere dann sehr schwierig wird, wenn man womöglich einem derartigen Leiteranschluß dann auch noch beispielsweise aus Gründen des Berührungsschutzes eine Art Isolierstoffgehäuse zuordnen wollte.In the case of conductor connections with busbars of the generic type, there are no such guide options, with the fact that the placement of the clamping body on the back bend from the middle busbar region already requires considerable manual dexterity from the outset and is particularly difficult when it is possible to connect such a conductor also wanted to assign a type of insulating material housing, for example to protect against accidental contact.

Der vorliegenden Erfindung liegt von daher die Aufgabe zugrunde, einen Leiteranschluß der gattungsgemäßen Art zu schaffen, der eine einfache, zuverlässige Führungsmöglichkeit für den oder die Klemmkörper und zugleich darüberhinaus einen Berührungsschutz bietet.The present invention is therefore based on the object of creating a conductor connection of the generic type which offers a simple, reliable guiding possibility for the clamping body or bodies and at the same time also provides protection against contact.

Die erfindungsgemäße Lösung besteht in einem die Stromschiene aufnehmenden Isolierstoffgehäuse, das nach oben offen ist und in Längserstreckung der Stromschiene verlaufende Führungsnuten aufweist, wobei am Klemmkörper seitlich Führungsnasen vorgesehen sind, die im mittleren Stromschienenbereich in die Führungsnuten des Isolierstoffgehäuses einsetzbar sind.The solution according to the invention consists in an insulating material housing which receives the busbar and which is open at the top and has guide grooves running in the longitudinal direction of the current rail, guide lugs being provided on the side of the clamping body, which can be inserted into the guide grooves of the insulating material housing in the central busbar region.

Das nach oben offene Isolierstoffgehäuse bietet für den Bereich der Stromschiene und des Klemmkörpers einen guten Berührungsschutz und bietet dank der in Längserstreckung der Stromschiene verlaufenden Führungsnuten die Möglichkeit einer genauen Hinführung des oder der Klemmkörper, jeweils vom mittleren Stromschienenbereich aus, zur Klemmstelle, d. h. zu der oder den Rückbiegungen und den dort zunächst frei und ohne Beeinträchtigung durch den Klemmkörper aufgelegten anzuschließenden elektrischen Leiter. Durch die definierte Aufnahme der Stromschiene im Isolierstoffgehäuse einerseits und die definierte Haltung und Führung des oder der Klemmkörper andererseits entfallen dabei jedwede weitere Maßnahmen zur zielgerichteten Hinführung der Klemmkörper zur Klemmstelle.The insulating plastic housing, which is open at the top, offers good protection against contact for the area of the busbar and the clamping body and, thanks to the guide grooves running in the longitudinal direction of the busbar, offers the possibility of a precise guidance of the clamping body or bodies, in each case from the middle busbar area, to the clamping point, i.e. H. to the back bend or bends and the electrical conductor to be connected, which is initially placed there freely and without being affected by the clamping body. The defined mounting of the busbar in the insulating material housing on the one hand and the defined holding and guiding of the clamping element (s) on the other hand eliminate any further measures for the targeted guidance of the clamping element to the clamping point.

Ein derartiges Isolierstoffgehäuse ist auch ein denkbar einfach herzustellendes Teil, da es in seiner Längserstreckung einschließlich der Führungsnuten in Parallelität zu der Stromschiene ausgerichtet ist. Das Isolierstoffteil kann gegebenenfalls sogar ein einfaches Extruderprofil sein.Dies gilt insbesondere dann, wenn, gemäß einer bevorzugten Ausführungsform, die Führungsnasen am Klemmkörper elastisch verformbar ausgebildet sind, so daß sie im mittleren Stromschienenbereich schnappend federnd von oben in die Führungsnuten eingedrückt werden können. Anderenfalls wäre, wie gemäß einer weiteren Ausführungsform vorgesehen, hier im mittleren Bereich im Isolierstoffgehäuse beidseitig an der Innenwand jeweils eine von oben in die Führungsnuten mündende Einführungsnut für die Führungsnasen vorzusehen.Such an insulating material housing is also a very simple part to manufacture, since its longitudinal extension, including the guide grooves, is aligned in parallel with the busbar. The insulating material part can even be a simple extruder profile, in particular if, according to a preferred embodiment, the guide lugs on the clamping body are designed to be elastically deformable, so that they can be snap-fitted into the guide grooves in the middle of the busbar area. Otherwise, as provided according to a further embodiment, an insertion groove for the guide lugs opening into the guide grooves from above would be provided in the middle region in the insulating material housing on both sides.

In weiterer zweckmäßiger Ausgestaltung ist dem Isolierstoffgehäuse eine aufsetzbare Abdeckung zugeordnet, die den Berührungsschutz vervollständigt.In a further expedient refinement, a cover which can be placed on and which completes the protection against contact is assigned to the insulating material housing.

Das Isolierstoffgehäuse kann ferner gemäß einer weiteren bevorzugten Ausführungsform mit einem Rastfuß zur Aufrastung auf Normtagschienen versehen sein. Dabei ist zweckmäßig das Isolierstoffgehäuse auch mit seitlich ebenen Flächen versehen, so daß mehrere derartige Isolierstoffgehäuse aneinander anreihbar sind. In weiterer zweckmäßiger Ausgestaltung ist dabei auf beiden Seiten des Isolierstoffgehäuses jeweils im unteren Bereich eine gegenüber dem oberen Bereich verbreiterte Anreihzone gebildet. Hierdurch entsteht bei der Anreihung im oberen Bereich zwischen zwei benachbarten, angereihten Isolierstoffgehäusen dann ein Freiraum, mit dessen Hilfe problemlos nach Tätigung der Anschlüsse die Abdeckung auf das lsolierstoffgehäuse aufgesetzt werden kann.According to a further preferred embodiment, the insulating material housing can also be provided with a latching foot for snapping onto standard day rails. The insulating housing is also expediently provided with laterally flat surfaces, so that a plurality of insulating housings of this type can be strung together. In a further expedient embodiment, a baying zone widened relative to the upper area is formed on both sides of the insulating material housing in the lower area. This creates a space in the upper area between two adjacent, insulated housing, with the help of which the cover can easily be placed on the insulating housing after the connections have been made.

In dem dargestellten Ausführungsbeispiel beinhaltet der Leiteranschluß eine Stromschiene 1, die an ihren beiden Enden jeweils mit einer Rüchbiegung 2, parallel zu sich selbst, versehen ist. Der Leiteranschluß beinhaltet ferner ein im Querschnitt U-förmiges Isolierstoffgehäuse 3, in dessen Bodenbereich eine Aufnahmenut 4 für die Stromschiene 1 vorgesehen ist. Das Isolierstoffgehäuse 3 ist in seiner Längserstreckung entsprechend der Längserstreckung der Stromschiene 1 orientiert und ist nach oben offengehalten. Das Isolierstoffgehäuse 3 weist unterseitig einen Rastfuß 5 zur Aufrastung des Isolierstoffgehäuses 3 auf einer Normtragschiene 6 (siehe Figur 2) auf.In the illustrated embodiment, the conductor connection includes a busbar 1, which is provided at both ends with a bending 2, parallel to itself. The conductor connection also includes a cross-sectionally U-shaped insulating material housing 3, in the bottom of which rich a receiving groove 4 is provided for the busbar 1. The length of the insulating housing 3 is oriented according to the longitudinal extent of the busbar 1 and is kept open at the top. The insulating material housing 3 has a locking foot 5 on the underside for snapping the insulating material housing 3 onto a standard mounting rail 6 (see FIG. 2).

In seinem oberen Bereich ist das Isolierstoffgehäuse 3 im Bereich beider Innenwände jeweils mit einer durchgehenden Führungsnut 7 versehen.In its upper area, the insulating material housing 3 is provided with a continuous guide groove 7 in the area of both inner walls.

Der Leiteranschluß beinhaltet ferner mindestens einen Klemmkörper 8, der im dargestellten Ausführungsbeispiel durch einen U-förmigen Druckbügel 9 gebildet ist, der in seinem oberen Bereich mit einem Muttemstück 10 verbunden ist, in das als Klemmglied eine Klemmschraube 11 eingeschraubt ist Das Muttemstück 10 ist zweckmäßig in nach oben offenen Ausklinkungen 12 des U-förmigen Druckbügels angeordnet und weist beidseitig nach außen über den U-förmigen Druckbügel 10 vorstehende Führungsnasen 13 auf, mit denen der Klemmkörper 8 insgesamt zielgenau in den Führungsnuten 7 des Isolierstoffgehäuses 3 hin und her verschieblich geführt ist.The conductor connection further includes at least one clamping body 8, which is formed in the illustrated embodiment by a U-shaped pressure bracket 9, which is connected in its upper region to a nut piece 10, into which a clamping screw 11 is screwed as a clamping member. The nut piece 10 is expediently in arranged upward open notches 12 of the U-shaped pressure bracket and has on both sides outwardly above the U-shaped pressure bracket 10 protruding guide lugs 13 with which the clamping body 8 is precisely slidably guided back and forth in the guide grooves 7 of the insulating material housing 3.

In Verbindung mit der speziellen Gestaltung der Stromschiene 1 mit ihren Rückbiegungen 2 besteht das Erfordernis, die Klemmkörper 8 vom mittleren Bereich der Stromschiene aus gesehen nach außen zu verschieben, so daß, bezogen auf die Rückbiegungen 2, die Klemmkörper 8 von innen her auf die Rückbiegungen 2 geschoben werden können. Zu diesem Zweck müssen die Klemmkörper 8 im mittleren Stromschienenbereich und damit im mittleren Bereich des Isolierstoffgehäuses 3 mit ihren Führungsnasen 13 in die Führungsnuten 7 eingesetzt werden können.In connection with the special design of the busbar 1 with its back bends 2, there is a need to move the clamp body 8 from the central region of the busbar as seen from the outside, so that, based on the back bends 2, the clamp body 8 from the inside to the back bends 2 can be pushed. For this purpose, the clamping bodies 8 with their guide lugs 13 must be able to be inserted into the guide grooves 7 in the middle conductor rail area and thus in the middle area of the insulating material housing 3.

Im dargestellten Ausführungsbeispiel sind hierzu in eben diesem mittleren Bereich von oben her in die Führungsnuten 7 mündende beidseitige Einführungsnuten 14 vorgesehen.In the exemplary embodiment shown, two-sided insertion grooves 14 opening into the guide grooves 7 from above are provided in this middle region.

In Abweichung hiervon besteht jedoch auch die Möglichkeit, die Führungsnasen 13 selbst so ausreichend elastisch verformbar zu gestalten, gegebenenfalls mit einer gewissen Elastizität der emporstehenden Seitenwände des Isolierstoffgehäuses selbst, daß man im mittleren Bereich des Isolierstoffgehäuses auch ohne Zuhilfenahme von Einführungsnuten 14 die Führungsnasen 13 in die Führungsnuten 7 eindrücken kann. In einem solchen Fall kann das Isolierstoffgehäuse 3 in besonders einfacher Weise insgesamt als Extruderprofil hergestellt werden.In deviation from this, however, there is also the possibility of making the guide lugs 13 themselves sufficiently elastically deformable, possibly with a certain elasticity of the upstanding side walls of the insulating material housing itself, that the guide lugs 13 can be inserted into the middle region of the insulating material housing even without the aid of insertion grooves 14 Guide grooves 7 can press. In such a case, the insulating material housing 3 can be produced in a particularly simple manner as an extruder profile.

Dem Isolierstoffgehäuse 3 wird zweckmäßig noch eine zusätzliche obere Abdeckung 15 zugeordnet, die seitliche Rastfüße 16 hat, für die außen oben das Isolierstoffgehäuse 3 durchgehende längs verlaufende Nuten 17 vorgesehen sind. Die Abdeckung 15 ihrerseits kann mit Aufnahmen 18 zur Anbringung von Bezeichnungsträgern 19 versehen sein.An additional upper cover 15 is expediently assigned to the insulating material housing 3, which has lateral latching feet 16, for which longitudinal grooves 17 running continuously through the outside of the insulating material housing 3 are provided. The cover 15 in turn can be provided with receptacles 18 for attaching label holders 19.

Die Funktionsweise eines derartigen Leiteranschlusses sei im Zusammenhang mit Figur 4 erläutert. Ausgehend von einem Anwendungsfall, bei dem auf beiden Rückbiegungen 2 der Stromschiene 1 dickdrähtige Leiter anzuschließen sind, werden zunächst im mittleren Bereich der Stromschiene und des Isolierstoffgehäuses, entweder federnd schnappend oder unter Zuhilfenahme der Einführungsnuten 14 nacheinander zwei Klemmkörper 8 mit ihren Führungsnasen 13 in die Führungsnuten 7 des Isolierstoffgehäuses 3 eingesetzt. Sie können geringfügig aus der Mitte nach außen verlagert in Bereitstellung geschoben werden. Es kann dann jeweils ein Leiter unbehindert oben auf die Rückbiegung 2 der Stromschiene 1 aufgelegt werden. Danach wird exakt geführt von innen her der betreffende Klemmkörper 8 über die Rückbiegung 2 und den aufliegenden Leiter geschoben und der Anschluß dann durch Anziehen der Klemmschraube 11 getätigt.The operation of such a conductor connection will be explained in connection with Figure 4. Based on an application in which thick wire conductors are to be connected on both rear bends 2 of the busbar 1, two clamping bodies 8 with their guide lugs 13 into the guide grooves are first successively in the central region of the busbar and the insulating material housing, either resiliently snapping or with the aid of the insertion grooves 14 7 of the insulating material housing 3 used. They can be shifted slightly from the center to the outside in preparation. One conductor can then be placed freely on top of the back bend 2 of the busbar 1. Then the clamp body 8 in question is guided exactly from the inside over the back bend 2 and the overlying conductor and the connection is then made by tightening the clamp screw 11.

Es sind ohne weiteres auch Anwendungsfälle möglich, bei denen nur am einen Ende der Stromschiene 1 auf der dort befindlichen Rückbiegung 2 ein Leiteranschluß mittels eines Klemmkörpers 8 erfolgt. Auf das andere Stromschienenende bzw. die dort befindliche Rückbiegung kann dann beispielsweise ein am Ende eines dort anzuschließenden Leiters befindlicher Kabelschuh einfach von oben aufgelegt werden, der dann mittels einer Schraube dort festgelegt wird. Um bezüglich dieser Anschlußtechniken flexibel zu sein, haben zweckmäßig die Rückbiegungen 2 zusätzlich Gewindebohrungen 20, um einen Kabelschuh darauf festschrauben zu können.Applications are also readily possible in which a conductor connection is made by means of a clamping body 8 only at one end of the busbar 1 on the back bend 2 located there. A cable lug, for example, located at the end of a conductor to be connected there can then simply be placed on the other busbar end or the back bend located there, which is then fixed there by means of a screw. In order to be flexible with regard to these connection techniques, the back bends 2 have additional threaded holes 20 in order to be able to screw a cable lug onto them.

Die Isolierstoffgehäuse 3 sind seitlich ebenflächig ausgebildet, um ihre Anreihbarkeit aneinander, wie in Figur 1 illustriert, zu gewährleisten. Zweckmäßig ist dabei seitlich außen an den Isolierstoffgehäusen 3 an deren unterem Bereich eine gegenüber dem oberen Bereich verbreiterte Anreihzone 21 gebildet. Auf diese Weise bildet sich nach der Anreihung derart gestalteter Isolierstoffgehäuse 3 aneinander jeweils zwischen zwei Isolierstoffgehäusen in deren oberem Bereich eine Freizone aus, die ein problemloses Aufsetzen und Wiederabnehmen der Abdeckung 15 auch nach Durchführung der Anreihung gewährleistet.The insulating material housings 3 are flat on the sides in order to ensure that they can be aligned with one another, as illustrated in FIG. 1. In this case, a baying zone 21 widened relative to the upper area is expediently formed on the outside of the insulating material housings 3 at the lower area thereof. In this way, after the arrangement of the insulating material housings 3 designed in this way, a free zone is formed between two insulating material housings in their upper region, which ensures that the cover 15 can be put on and removed again without any problems even after the arrangement has been carried out.

Ein derartiger Leiteranschluß ist aufgrund seiner vorstehend beschriebenen Ausgestaltung auch insoweit außerordentlich flexibel, als herstellerseitig dem Anwender die Stromschienen mit dem Isolierstoffgehäuse einerseits und die Klemmkörper andererseits sowie schließlich auch die Abdeckungen gesondert als Bausteine eines Bausatzes zur Verfügung gestellt werden können. Der Anwender kann dann in freier Wahl die Bestückung mit nur einem oder mit zwei Klemmkörpem durchführen.Such a conductor connection is also extremely flexible due to the design described above, in that the manufacturer can provide the user with the busbars with the insulating housing on the one hand and the clamping bodies on the other hand and finally also the covers as modules of a kit. The user can then carry out the assembly with just one or two clamping bodies.
