The ends (5.1) of legs on a U-shaped leaf spring (5) run into these holes and insert into the square-shaped holes from the underside of the live rail/bus bar so that the ends of the legs of the leaf spring extend opposite to the plug-in direction of plug-in contacts (9) for a crosswise link.

Description

Die Erfindung betrifft eine elektrische Verbindungsklemme, insbesondere Reihenklemme mit einer aus einem flachen Material gefertigten Stromschiene, die mindestens zwei Steckanschlüsse zum lösbaren Einstecken jeweils eines in sich ungefederten, steifen Steckkontaktes eines Querbrückers besitzt, der die Stromschienen benachbart zueinander angeordneter Klemmen elektrisch miteinander verbindet, wobei die Steckanschlüsse in Form von federnden Steckbuchsen ausgebildet sind in der Weise, daß die Schenkelenden einer als separates Bauteil gefertigten, U-förmig gebogenen Blattfeder mit ihrer jeweils nach außen gerichteten Federkraft mit den nach innen gerichteten Kontaktanlageflächen der Stromschiene zusammenarbeiten.The invention relates to an electrical Connection terminal, in particular terminal block with one from a flat Material made busbar that at least two plug connections for releasable insertion one in each unsprung, stiff plug contact of a cross bridge that has the Busbars adjacent to each other arranged terminals electrically with each other connects, the plug connections in the form of resilient sockets are trained in the way that the leg ends one as a separate Component manufactured, U-shaped curved Leaf spring with its outward directed spring force with the inside directional contact contact surfaces of the Cooperate busbar.

Klemmen dieses Typs sind aus der FR 2 803 441 B1 bekannt. Die nach innen gerichteten Kontaktanlageflächen der Stromschiene sind durch hochgestellte, d.h. aus der Flächenerstreckung der Stromschiene herausgebogene Stromschienenendstücke gebildet, die sich entgegengesetzt zur Einsteckrichtung der Brücker-Steckkontakte erstrecken, wohingegen sich die Klemmschenkelenden der U-förmigen Blattfeder in Einsteckrichtung der Steckkontakte des Brückers bis hin zu den hochgestellten Stromschienenendstücken der Stromschiene erstrecken, so daß die eingesteckten Brücker-Steckkontakte zwischen den Klemmschenkelenden der Blattfeder und den hochgestellten Stromschienenendstücken geklemmt werden.Terminals of this type are from the FR 2 803 441 B1 known. The inside directional contact contact surfaces of the Busbars are replaced by superscript, i.e. from the area extension of the Busbar bent out busbar end pieces formed that itself opposite to the insertion direction of the Brücker plug contacts extend, whereas the clamping leg ends of the U-shaped leaf spring in the direction of insertion of the plug contacts of the jumper up to the raised busbar end pieces extend the busbar, so that the inserted jumper plug contacts between the clamping leg ends the leaf spring and the superscript Busbar end pieces are clamped.

Diese bekannten Klemmen haben wegen der Größe der Blattfeder eine beachtliche Bauhöhe und erfordern zudem, daß die Baulänge der Brücker-Steckkontakte so groß zu wählen ist, daß die Steckkontakte beim Einsteckvorgang an den relativ langen Klemmschenkeln der Blattfeder vorbei bis hin zu den unteren, in der Nähe der Flächenerstreckung der Stromschiene liegenden Klemmbereichen der Steckanschlüsse vorgeschoben werden können.These known clamps have because of The size of the leaf spring is considerable Overall height and also require that the overall length the jumper plug contacts so big to choose is that the plug contacts at Insertion process on the relatively long Clamp legs of the leaf spring over to towards the lower ones, near the Area extension of the conductor rail lying clamping areas of the plug connections can be advanced.

Aufgabe der Erfindung ist es, kleinbauende Steckanschlüsse für das Einstecken der Brücker-Steckkontakte zu entwickeln, die die Bauhöhe der Klemmen des eingangs genannten Typs insgesamt verringern.The object of the invention is small-scale Plug connections for plugging in the jumper plug contacts too develop the overall height of the terminals of the type mentioned at the beginning reduce.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß zur Bildung der Steckanschlüsse in der Stromschiene viereckförmige Durchstecköffnungen vorhanden sind, in die die Schenkelenden der Blattfeder eintauchen, und daß die Schenkelenden der Blattfeder von der Unterseite der Stromschiene in die viereckförmigen Durchstecköffnungen eingesetzt sind derart, daß sich die Schenkelenden entgegengesetzt zur Einsteckrichtung der Steckkontakte des Querbrückers erstrecken.This object is achieved according to the invention solved that to form the plug connections square-shaped in the conductor rail Push-through openings available are in the leg ends of the leaf spring immerse and that the thigh ends the leaf spring from the bottom the busbar into the square Push-through openings are used such that the thigh ends are opposite for the direction of insertion of the plug contacts of the cross bridge.

Die erfindungsgemäße Lösung hat zwei wesentliche Vorteile. Zum einen zeigt sie, daß die Klemmbereiche der federbelasteten Steckanschlüsse in die Ebene der Flächenerstreckung der Stromschiene hineinverlegt werden können, wodurch die Bauhöhe der Klemme insgesamt verringert werden kann.The solution according to the invention has two essential advantages. On the one hand shows them that the clamping areas of the spring-loaded Plug connections in the level the surface area of the conductor rail can be relocated, whereby the Overall height of the clamp reduced can be.

Zum anderen zeigt die Lehre der Erfindung auch, daß die Anordnung der U-förmigen Blattfeder unterhalb der Stromschiene sehr platzsparend ist und auch die Steckbarkeit der Querbrücker verbessert ist, da nunmehr die Klemmbereiche der Steckanschlüsse beim Einstecken der Brücker-Steckkontakte voreilend sind, d.h. gleich am Beginn des Steckvorgangs positioniert sind, und die Brücker-Steckkontakte beim Einsteckvorgang nicht mehr an den ggf. längeren Klemmschenkeln der U-förmigen Blattfeder vorbeigeschoben werden müssen.On the other hand, the teaching of the invention shows also that the arrangement of the U-shaped Leaf spring below the track is very space-saving and also the pluggability the cross bridge is improved, now the clamping areas of the plug connections when plugging in the jumper plug contacts are leading, i.e. equal positioned at the beginning of the plugging process are, and the jumper plug contacts at No longer insert the longer clamping legs of the U-shaped Leaf spring must be pushed past.

Eine bevorzugte Ausführungsform der Erfindung sieht vor, daß die Viereckform der Durchstecköffnungen seitliche Anschläge aufweist, die den nach außen gerichteten maximalen Federweg der Schenkelenden der Blattfeder begrenzen, und daß der in Federwegrichtung freie Durchgang zwischen den seitlichen Begrenzungsanschlägen gleich oder größer ist als die quer zur Federwegrichtung gemessene Breite der Brücker-Steckkontakte, deren in Federwegrichtung gemessene Tiefe größer ist als der Abstand der seitlichen Begrenzungsanschläge von der nach innen gerichteten Kontaktanlagefläche der Stromschiene.A preferred embodiment of the invention provides that the square shape of the push-through openings, lateral stops that has the outside directed maximum travel of the Limit the leg ends of the leaf spring, and that the free in the travel direction Passage between the side Limit stops equal or larger is measured as transverse to the direction of travel Width of the jumper plug contacts, their depth measured in the direction of travel is greater than the distance between the sides Limit stops from the inside directional contact contact surface of the Busbar.

Die vorstehenden Merkmale gemäß der Erfindung verbessern den Selbstklemmeffekt der U-förmigen Blattfeder in den Durchstecköffnungen der Stromschiene. Die Klemmschenkelenden der Blattfeder können mit einer höheren Vorspannung in die Durchstecköffnungen der Stromschiene eingebaut (eingesetzt) werden, da sie sich mit ihrer Federkraft an den seitlichen Begrenzungsanschlägen in den Durchstecköffnungen abstützen können. Der Einbau ist somit "selbsttragend", d.h. die Blattfeder trägt sich selbst und überträgt keine Klemmkraft auf das Isolierstoffgehäuse, und zwar auch dann nicht, wenn nur ein Steckanschluß der beiden von derselben U-förmigen Blattfeder bedienten Steckanschlüsse belegt ist.The above features according to the invention improve the self-locking effect the U-shaped leaf spring in the push-through openings the track. The Clamp leg ends of the leaf spring can with a higher preload in the Through openings of the busbar be installed (used) because they with their spring force on the side Limit attacks in the Can support push-through openings. The Installation is therefore "self-supporting", i.e. the leaf spring carries itself and transfers no clamping force to the Insulated housing, even then not if only a plug connection of the both from the same U-shaped leaf spring operated plug connections occupied is.

Durch die seitlichen Begrenzungsanschläge in den Durchstecköffnungen der Stromschiene wird auch erreicht, daß die Klemmkraft der Blattfeder erhöht werden kann (wodurch die Erstreckungslänge der Klemmschenkel der Blattfeder verkleinert werden kann), ohne daß dadurch der gewünschte "weichere" Arbeitsvorgang'beim Einstecken und/oder Lösen der Querbrücker nennenswert beeinflußt wird. Beim Einstecken der Brücker-Steckkontakte muß lediglich ein gewollter geringer Federweg überwunden werden, der sich aus der Bemessung der Querschnittsabmessungen der Brücker-Steckkonktakte relativ zu den Abmessungen der in die Stromschiene eingestanzten Durchstecköffnungen ergibt.Through the side limit stops in the through openings of the busbar is also achieved that the Clamping force of the leaf spring can be increased can (whereby the extension length of the Clamp leg of the leaf spring reduced can be) without the desired "softer" operation during Insert and / or release the cross jumper is significantly influenced. When plugging in the jumper plug contacts must just a deliberate little travel be overcome, which arises from the Dimensioning the cross-sectional dimensions of the Brücker plug contacts relative to the Dimensions of the in the busbar punched through openings.

Eine verbesserte Steckbarkeit und insbesondere eine genauere Führung der Brücker-Steckkontakte wird beim Einsteckvorgang dann erreicht, wenn gemäß einer zweckmäßigen Ausführungsform der Erfindung die viereckförmigen Durchstecköffnungen in der Stromschiene in der Form von viereckigen Materialdurchzügen gefertigt sind, die jeweils einen in Einsteckrichtung der Steckkontakte des Querbrückers sich erstreckenden Lochkragen haben. Improved pluggability and in particular a more precise management of the Brücker plug contacts is during the insertion process reached when according to a expedient embodiment of the invention the square through openings in the track in the shape made of square material passages are, each one in the direction of insertion the plug contacts of the cross jumper extending hole collar to have.

Die Materialstärke der vorgenannten Lochkragen trägt auch dazu bei, den Stromleitungsquerschnitt der Stromschiene in deren Längserstreckungsrichtung zu verbessern, wie dies insbesondere bei elektrischen Durchgangsklemmen gewünscht ist.The material thickness of the aforementioned collar also contributes to the power line cross section the track in their direction of longitudinal extension too improve like this especially at electrical feed-through terminals required is.

Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnungen näher beschrieben. Es zeigen:

2 shows a horizontal section through the terminal block according to FIG. 1 along the line AA in FIG. 1.

In Fig. 1 ist ausschnittsweise eine Reihenklemme 1 im Bereich ihrer Brücker-Einsteckschächte 2 und mit einem Isolierstoffgehäuse 3 dargestellt. In die Klemme ist eine Stromschiene eingebaut. Unterhalb der Stromschiene 4 ist eine U-förmige Blattfeder 5 über Fixierhilfen 6 und 7 des Isolierstoffgehäuses 3 positioniert. Mit beiden Schenkelenden 5.1 klemmt die Blattfeder 5 in dem viereckigen Materialdurchzug 8. Der Materialdurchzug 8 verengt sich benachbart zu den Klemmschenkelenden 5.1 zu einem kleineren Durchzugsbereich 8.1, der im Querschnitt kleiner bemessen ist und der der Aufnahme des Steckkontaktes 9 des Querbrückers 9.1 dient. Dabei ragt der Brücker-Steckkontakt 9 mit der dem Schenkelende 5.1 zugewandten Längsseite in den Bereich des Materialdurchzugs 8 hinein.In Fig. 1 is a section Terminal 1 in the area of their jumper slots 2 and with an insulating housing 3 shown. In a fix a track is installed. Below the busbar 4 is one U-shaped leaf spring 5 via fixing aids 6 and 7 of the insulating material housing 3 positioned. With both thigh ends 5.1 clamps the leaf spring 5 in the square material passage 8. The Material passage 8 narrows adjacent to the clamping leg ends 5.1 a smaller passage area 8.1, the is smaller in cross section and of receiving the plug contact 9 of the Cross jumper 9.1 is used. The protrudes Jumper plug contact 9 with the Leg end 5.1 facing the long side in the area of the material passage 8 into it.

Beim Stecken des Querbrückers 9.1 in den Brückerschacht 2 schiebt sich der Brücker-Steckkontakt 9 mit seiner angeschrägten Spitze zwischen das Schenkelende 5.1 der Blattfeder 5 einerseits und die angefasten Randbereiche des verkleinerten Durchzugsbereichs 8.1 andererseits. Dabei hebt der Brücker-Steckkontakt 9 den Schenkel 5.1 der Blattfeder 5 durch Überwindung seiner Vorspannung von den seitlichen Begrenzungsanschlägen 10 in dem,Materialdurchzug 8 ab und schiebt sich somit zwischen das Klemmschenkelende 5.1 und die Stromschiene 4, wobei der verkleinerte Durchzugsbereich 8.1 den Kontakt zur Stromschiene 4 sicherstellt.When inserting the cross jumper 9.1 in the Bridge shaft 2 pushes itself Jumper plug contact 9 with its beveled Tip between the end of the leg 5.1 the leaf spring 5 on the one hand and the chamfered edge areas of the reduced Passage area 8.1 on the other hand. The jumper plug contact lifts 9 the leg 5.1 of the Leaf spring 5 by overcoming its Preload from the side limit stops 10 in, material passage 8 and thus pushes itself between the clamping leg end 5.1 and the busbar 4, the scaled down Passage area 8.1 den Ensures contact to busbar 4.

Es liegt auf der Hand, daß der in eine elektrische Klemme integrierte Steckanschluß in der erfindungsgemäßen Form einer fremdgefederten Steckbuchse nicht nur zum Einstecken der Steckkontakte eines Querbrückers geeignet ist, sondern auch dafür dienen kann, Prüfstecker oder sonstige steckbare Verbindungsteile wie auch steckbare Massivleiter einzustecken bzw. mit der Stromschiene der Klemme elektrisch zu verbinden.It is obvious that the one electrical terminal integrated plug connection in the form according to the invention an externally sprung socket only for inserting the plug contacts a cross bridge is suitable, but can also serve as test plugs or other pluggable connecting parts such as also insert pluggable solid conductors or with the busbar of the terminal to connect electrically.
