Description

Die Erfindung betrifft eine Steckbrücke für elektrische Anschluß- und/oder Verbindungsklemmen, insbesondere Reihenklemmen, zum federnden Eingreifen in Öffnungen in Stromschienen und zum elektrischen Kontaktieren von Stromschienen mindestens zweier Anschluß- und/oder Verbindungsklemmen, mit einer Brückenschiene, wobei die Brückenschiene eine Schienenleiste und mehrere mit der Schienenleiste verbundene Stecker aufweist und wobei jeder Stecker mindestens zwei im wesentlichen parallel zueinander angeordnete Kontaktschenkel aufweist, von denen wenigstens einer federnd ausgebildet ist. Daneben betrifft die Erfindung noch eine elektrische Anschluß- und/oder Verbindungsklemmen, insbesondere Reihenklemmen, mit einem Gehäuse, mit mindestens einer Stromschiene, mit mindestens zwei Anschlußelementen und mit einer lösbaren Steckbrücke.The invention relates to a jumper for electrical connection and / or connection terminals, in particular terminal blocks, for resilient engagement in openings in busbars and for electrically contacting busbars at least two connection and / or connection terminals, with a bridge rail, wherein the bridge rail a rail and a plurality having plug connected to the bus bar and wherein each plug has at least two substantially mutually parallel contact legs, of which at least one is resilient. In addition, the invention also relates to an electrical connection and / or connection terminals, in particular terminal blocks, with a housing, with at least one busbar, with at least two connecting elements and with a detachable jumper.

Elektrische Anschluß- und/oder Verbindungsklemmen, insbesondere Reihenklemmen, sind seit Jahrzehnten bekannt und werden millionenfach bei der Verdrahtung elektrischer Anlagen und Geräte verwendet. Die Klemmen werden meist auf Tragschienen aufgerastet, welche ihrerseits häufig in einer Mehrzahl in einem Schaltschrank angeordnet sind. Als Leiteranschlußelemente werden in Reihenklemmen überwiegend Schraubklemmen oder Zugfederklemmen verwendet. Das Klemmprinzip bei Zugfederklemmen ist ähnlich dem der Schraubtechnik. Während bei der Schraubklemme eine Zughülse durch die Betätigung der Klemmenschraube den Leiter gegen den Strombalken zieht, wird bei der Zugfederklemme diese Aufgabe von der Zugfeder übernommen. Daneben gibt es jedoch auch Reihenklemmen bekannt, deren Leiteranschlußelemente Schneidmesser aufweisen, die die Isolierung der eingeführten Leiter durchtrennen und die Seele des Leiters kontaktieren.Electrical connection and / or connection terminals, in particular terminal blocks, have been known for decades and are used a million times in the wiring of electrical systems and devices. The terminals are usually snapped onto mounting rails, which in turn are often arranged in a plurality in a control cabinet. As conductor connection elements predominantly screw terminals or tension spring terminals are used in terminal blocks. The clamping principle with tension spring clamps is similar to that of screwdriving technology. While with the screw terminal a tension sleeve pulls the conductor against the current bar by the operation of the clamping screw, this task is taken over by the tension spring at the tension spring clamp. However, there are also known terminal blocks whose conductor connection elements have cutting blades which cut through the insulation of the inserted conductors and contact the core of the conductor.

Elektrische Reihenklemmen sind in der Regel Verbindungsklemmen, so daß sie mindestens zwei Leiteranschlußelemente aufweisen, die über eine elektrisch leitende Verbindungsschiene, die Stromschiene, elektrisch miteinander verbunden sind. Derartige Reihenklemmen werden auch als Durchgangsklemmen bezeichnet. Neben diesem Grundtyp der Reihenklemmen gibt es darüber hinaus eine Vielzahl von unterschiedlichen Reihenklemmentypen, die speziell den jeweiligen Anwendungsfällen angepaßt sind. Als Beispiel seien hier Doppelstock-, Dreistock- oder Vierstock-Klemmen sowie Dreileiter- oder Vierleiter-Klemmen genannt, die dann jeweils eine entsprechend größere Anzahl an Leiteranschlußelementen aufweisen. Doppelstock-, Dreistock- oder Vierstock-Klemmen, die allgemein auch als Etagenklemmen bezeichnet werden, weisen dabei zwei, drei oder vier übereinander, in verschiedenen Ebenen, angeordnete Stromschienen auf, die jeweils zwei Leiteranschlußelemente elektrisch miteinander verbinden.Electrical terminal blocks are usually connection terminals, so that they have at least two conductor connection elements which are electrically connected to one another via an electrically conductive connection rail, the busbar. Such terminal blocks are also referred to as feed-through terminals. In addition to this basic type of terminal blocks, there are In addition, a variety of different types of terminal block, which are specially adapted to the particular application. As an example, two-storey, three-storey or four-storey terminals as well as three-conductor or four-conductor terminals may be mentioned, which then each have a correspondingly larger number of conductor connection elements.

Zur Reduzierung des Verdrahtungsaufwandes bei nebeneinander auf einer Tragschiene aufgerasteten Reihenklemmen ist es bekannt, Steckbrücken mit einer entsprechenden Anzahl von Steckern zu verwenden, wobei die Stecker der Steckbrücke in entsprechenden Öffnungen in den Stromschienen der einzelnen Reihenklemmen eingesteckt werden, wodurch die einzelnen Stromschienen bzw. die einzelnen Reihenklemmen elektrisch miteinander verbunden werden.In order to reduce the wiring costs in juxtaposed on a mounting rail terminal blocks, it is known to use jumpers with a corresponding number of connectors, the plug of the jumper are plugged into corresponding openings in the busbars of the individual terminal blocks, whereby the individual busbars or the individual Terminal blocks are electrically connected together.

Eine eingangs beschriebene Steckbrücke bzw. eine eingangs beschriebene elektrische Anschluß- und/oder Verbindungsklemme ist beispielsweise aus der DE 44 11 306 C1 bekannt. Die bekannte Steckbrücke zeichnet sich dadurch aus, daß sie zwei nebeneinander angeordnete Brückenschienenabschnitte aufweist, an denen jeweils ein Kontaktschenkel pro Stecker ausgebildet ist, wobei die Federbelastung der Stecker parallel zur Längsrichtung der Schienenleiste erfolgt. Bei den beiden Brückenschienenabschnitten kann es sich dabei um einfache Stanzteile handeln, so daß die bekannte Steckbrücke sehr einfach hergestellt werden kann.A jumper described at the outset or an electrical connection and / or connection terminal described in the introduction is known, for example, from US Pat DE 44 11 306 C1 known. The known jumper is characterized in that it comprises two juxtaposed bridge rail sections, on each of which a contact leg per plug is formed, wherein the spring loading of the plug is parallel to the longitudinal direction of the rail. In the two bridge rail sections may be simple stampings, so that the known jumper can be easily made.

Aus der DE 42 23 540 A1 ist ebenfalls eine Steckbrücke bekannt, bei der jedoch die Federkräfte der Kontaktschenkel beim Einstecken in die Öffnung der Stromschienen quer zur Längsrichtung der Schienenleiste ausgerichtet sind. Beiden bekannten Steckbrücken ist jedoch gemeinsam, daß sie nur dann eingesetzt werden können, wenn gleiche Typen von Reihenklemmen aneinander gereiht sind. Beispielsweise können mit derartigen Steckbrücken mehrere baugleiche Durchgangsklemmen miteinander elektrisch verbunden werden.From the DE 42 23 540 A1 is also a jumper known, but in which the spring forces of the contact legs are aligned transversely to the longitudinal direction of the rail strip when plugged into the opening of the busbars. Both known jumpers is common, however, that they can only be used when the same types of terminal blocks are lined up. For example, a plurality of identical through terminals can be electrically connected to each other with such jumpers.

Aus der DE 195 33 992 C1 ist eine elektrische Etagenklemme mit zwei übereinander angeordneten Stromschienen bekannt, bei der eine elektrische Verbindung der beiden Stromschienen mittels einer Steckbrücke möglich ist, die lediglich einen Stecker aufweist, der in die beiden, zueinander fluchtenden Stecköffnungen in den Stromschienen eingesteckt werden kann. Im einzelnen besteht die bekannte Steckbrücke aus zwei flächig aneinanderliegenden Federkontakten, die im Bereich ihrer oberen, mit der oberen Stromschiene zusammenwirkenden Kontaktzone gegenläufig zueinander gerichtete Kröpfungen aufweisen. Dies führt beim Einstecken der Steckbrücke in die beiden Öffnungen der beiden Stromschienen zu einer federnden, gegensinnigen Aufspreizung der beiden Federkontakte in der Öffnung der oberen und der unteren Stromschiene, wodurch die Steckbrücke die beiden Stromschienen kontaktiert. Durch diese bekannte Steckbrücke läßt sich somit eine elektrische Verbindung von zwei Stromschienen einer Reihenklemme realisieren.From the DE 195 33 992 C1 is an electrical terminal block with two superimposed busbars is known in which an electrical connection of the two busbars by means of a jumper is possible, which has only one plug which can be inserted into the two mutually aligned plug openings in the busbars. In detail, the known jumper consists of two juxtaposed spring contacts, which have in the region of their upper, cooperating with the upper busbar contact zone in opposite directions to each other directed cranks. This results in the insertion of the jumper in the two openings of the two busbars to a resilient, opposing spreading of the two spring contacts in the opening of the upper and lower busbar, whereby the jumper contacts the two busbars. By this known jumper thus can be realized an electrical connection of two busbars of a terminal block.

Ferner wird auf die DE 27 36 664 A verwiesen, die die Merkmale des Oberbegriffs von Anspruch 1 offenbart.Further, on the DE 27 36 664 A referring to the features of the preamble of claim 1.

Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, eine Steckbrücke für elektrische Anschluß- und/oder Verbindungsklemmen zur Verfügung zu stellen, die es ermöglicht, auch unterschiedliche Typen von Reihenklemmen, insbesondere solche Reihenklemmen mit unterschiedlichen Leiteranschlußelementen, miteinander zu verbinden.The present invention is based on the object to provide a jumper for electrical connection and / or connection terminals, which makes it possible to connect different types of terminal blocks, in particular those terminal blocks with different conductor connection elements with each other.

Diese Aufgabe ist bei der eingangs beschriebenen Steckbrücke dadurch gelöst, daß die Stecker zwei übereinander angeordnete Kontaktbereiche zur Kontaktierung von zwei auf unterschiedlichen Ebene angeordneten Stromschienen zweier nebeneinander angeordneter Anschluß- und/oder Verbindungsklemmen aufweisen. Im Unterschied zu der aus der DE 44 11 306 C1 bekannten Steckbrücke, von der die Erfindung ausgeht, können mit der erfindungsgemäßen Steckbrücke somit auch Reihenklemmen elektrisch miteinander verbunden werden, die unterschiedliche Leiteranschlußelemente aufweisen, bei denen die die Leiteranschlußelemente einer Reihenklemme miteinander verbindenden Stromschienen auf unterschiedlichen Ebenen angeordnet sind.This object is achieved in the jumper described above in that the plug two superimposed contact areas for contacting two arranged on different levels busbars of two juxtaposed connection and / or connection terminals have. Unlike the one from the DE 44 11 306 C1 known jumper, from which the invention proceeds, can thus be electrically connected to each other with the jumper according to the invention also terminal blocks having different conductor terminal elements, in which the conductor terminal elements of a terminal block interconnecting busbars are arranged on different levels.

Aufgrund der unterschiedlichen Anschlußprinzipien sind nämlich bei herkömmlichen Reihenklemmen, bei denen die Leiteranschlußelemente als Schraubklemmen ausgebildet sind, die Stromschienen höher angeordnet als bei solchen Reihenklemmen, bei denen die Leiteranschlußelemente als Zugfederklemmen oder als Schneidmesser ausgebildet sind. Der relative Höhenunterschied der Stromschienen bezieht sich dabei auf den Abstand der einzelnen Stromschienen zur Tragschiene bei zwei nebeneinander auf einer Tragschiene aufgerastete Reihenklemmen. Durch das Vorsehen von mindestens zwei übereinander angeordneten Kontaktbereichen an jedem Stecker der Steckbrücke besteht somit die Möglichkeit, daß ein Stecker mit seinem unteren Kontaktbereich in eine Öffnung einer Stromschiene einer ersten Reihenklemme eingesteckt ist, während gleichzeitig ein anderer Stecker der Steckbrücke mit seinem oberen Kontaktbereich in der Öffnung einer Stromschiene einer zweiten Reihenklemme eingesteckt ist, deren Stromschiene in einer anderen Ebene liegt. Somit können mit einer Steckbrücke zwei auf unterschiedlichen Ebenen angeordnete Stromschienen zweier unterschiedlicher Reihenklemmen elektrisch miteinander verbunden.Because of the different connection principles namely in conventional terminal blocks, in which the conductor connection elements are designed as screw terminals, the busbars are arranged higher than in such terminal blocks, in which the conductor connection elements are designed as tension spring terminals or as a cutting blade. The relative height difference of the busbars refers to the distance between the individual busbars to the mounting rail with two adjacent to each other on a mounting rail snapped terminal blocks. By providing at least two superimposed contact areas on each plug of the jumper thus there is the possibility that a plug is plugged with its lower contact area in an opening of a busbar of a first terminal, while at the same time another plug of the jumper with its upper contact area in the Opening a busbar of a second terminal is inserted, the busbar is in a different plane. Thus, with a jumper two arranged on different levels busbars of two different terminal blocks electrically connected.

Gemäß einer bevorzugten Ausgestaltung der Erfindung weisen die Stecker bzw. die Kontaktschenkel unterschiedliche Breiten auf, wobei die Breite eines Steckers an die Breite der Stromschiene bzw. an die Breite der Öffnung in der Stromschiene angepaßt ist. In der Regel sind dabei die einzelnen Kontaktschenkel eines Steckers gleich breit, so daß alle Kontaktschenkel eines Stekkers schmaler als die Kontaktschenkel eines anderen Steckers sind. Dadurch ist es möglich, mit der erfindungsgemäßen Steckbrücke auch zwei - oder mehr - Reihenklemmen miteinander zu verbinden, die zum Anschluß von Leitern mit unterschiedlichen Leiterquerschnitten vorgesehen sind. Sollen an eine Reihenklemme Leiter mit einem größeren Leiterquerschnitt angeschlossen werden, so weist diese Klemme in der Regel - aufgrund der über die dikkeren Leiter fließenden höheren Ströme - auch eine Stromschienen mit einer größeren Breite und damit auch breiteren Öffnungen auf.According to a preferred embodiment of the invention, the plug or the contact legs have different widths, wherein the width of a plug is adapted to the width of the busbar or to the width of the opening in the busbar. As a rule, the individual contact legs of a plug are the same width, so that all the contact legs of a plug are narrower than the contact legs of another plug. This makes it possible, with the jumper according to the invention also two - or more - terminals to connect with each other, which are provided for connecting conductors with different conductor cross-sections. If a conductor with a larger conductor cross-section is to be connected to a terminal block, then this terminal usually also has a busbar with a greater width and thus also wider openings due to the higher currents flowing through the thicker conductors.

Gemäß einer vorteilhaften Ausgestaltung der erfindungsgemäßen Steckbrücke ist die Brückenschiene so ausgebildet, daß die Federkräfte der Stecker bzw. der Kontaktschenkel beim Einstecken in die Öffnungen der Stromschiene und beim Kontaktieren der Stromschiene parallel zur Längsrichtung der Schienenleiste gerichtet sind. Das Prinzip des Kontaktierens einer Stromschiene entspricht somit im wesentlichen dem Kontaktierungsprinzip der aus der DE 44 11 306 C1 bekannten Steckbrücke.According to an advantageous embodiment of the jumper according to the invention, the bridge rail is designed so that the spring forces of the plug or the contact legs are directed parallel to the longitudinal direction of the rail strip when plugged into the openings of the busbar and when contacting the busbar. The principle of contacting a busbar thus corresponds essentially to the contacting principle of the DE 44 11 306 C1 known jumper.

Im Unterschied zu dieser bekannten Steckbrücke weist die erfindungsgemäße Steckbrücke jedoch vorteilhafterweise drei im wesentlichen parallel zueinander angeordnete Kontaktschenkel auf, von denen zumindest der mittlere Kontaktschenkel federnd ausgebildet ist. Ist lediglich der mittlere Kontaktschenkel federnd ausgebildet - und sind die beiden äußeren Kontaktschenkel relativ steif ausgebildet -, so wird eine Verwindung der Steckbrücke senkrecht zur Längsrichtung der Schienenleiste und somit senkrecht zur Längsrichtung der Steckbrücke verhindert, wodurch das Einstecken der Steckbrücke in eine Vielzahl von nebeneinander angeordneten Reihenklemmen erleichtert wird.In contrast to this known jumper, however, the jumper according to the invention advantageously has three substantially mutually parallel contact legs, of which at least the middle contact leg is resilient. If only the middle contact limb is resiliently formed - and the two outer contact limbs are relatively stiff - twisting of the jumper perpendicular to the longitudinal direction of the rail strip and thus perpendicular to the longitudinal direction of the jumper is prevented, whereby the insertion of the jumper into a plurality of juxtaposed Terminal blocks is facilitated.

Gemäß einer weiteren vorteilhaften Ausgestaltung der erfindungsgemäßen Steckbrücke ist in mindestens einem Kontaktschenkel ein Längsschlitz ausgebildet. Bei der zuvor beschriebenen bevorzugten Ausgestaltung mit drei Kontaktschenkeln ist dabei zumindest der mittlere Kontaktschenkel mit dem Längsschlitz versehen. Durch die Ausbildung des Längsschlitzes wird die Rückstellkraft aufgrund des Auslenkens des Kontaktschenkels beim Einschieben in die Öffnung der Stromschiene vermindert, wodurch sich insbesondere die Einsteckkraft im oberen Kontaktbereich verringert, so daß sich die Einsteck- bzw. Durchsteckkraft durch die Öffnung einer oberen Stromschiene kaum von der Einsteckkraft in eine Öffnung in einer unteren Stromschiene unterscheidet.According to a further advantageous embodiment of the jumper according to the invention, a longitudinal slot is formed in at least one contact leg. In the above-described preferred embodiment with three contact legs, at least the middle contact leg is provided with the longitudinal slot. Due to the design of the longitudinal slot, the restoring force is reduced due to the deflection of the contact leg when inserted into the opening of the busbar, which in particular reduces the insertion force in the upper contact area, so that the insertion or penetration force through the opening of an upper busbar hardly from the Insertion force into an opening in a lower busbar is different.

Gemäß einer letzten vorteilhaften Ausgestaltung der erfindungsgemäßen Steckbrücke, die hier noch kurz erwähnt werden soll, weisen die Kontaktschenkel unterhalb des unteren Kontaktbereichs an mindestens einer Schmalseite eine Auflaufschräge auf. Hierdurch wird das Einstecken der Kontaktschenkel in eine Öffnung einer unteren Stromschiene weiter erleichtert. Darüber hinaus kann der untere Kontaktbereich nach oben durch einen seitlich vorspringenden Versatz begrenzt werden, so daß bei einer entsprechenden Dimensionierung der Öffnung ein definiertes Einstecken der Steckbrücke in die Reihenklemme gewährleistet ist.According to a last advantageous embodiment of the jumper according to the invention, which will be briefly mentioned here, the contact legs below the lower contact area on at least one narrow side of a run-on slope. As a result, the insertion of the contact legs in an opening of a lower busbar is further facilitated. In addition, the lower contact area can be limited upwards by a laterally projecting offset, so that with a corresponding dimensioning of the opening a defined insertion of the jumper is ensured in the terminal block.

Bei der eingangs beschriebenen elektrischen Anschluß- und/oder Verbindungsklemme, deren Stromschiene eine Öffnung zum federnden Eingreifen und elektrischen Kontaktieren einer Steckbrücke aufweist, ist die zuvor beschriebene Aufgabe dadurch gelöst, daß bei der Steckbrücke, die eine Brükkenschiene mit einer Schienenleiste und mehreren mit der Schienenleiste verbundenen Stecker aufweist, die Stecker zwei übereinander angeordnete Kontaktbereiche zum Kontaktieren von zwei auf unterschiedlichen Ebenen angeordneten Stromschienen zweier nebeneinander angeordneter Anschluß- und/oder Verbindungsklemmen aufweisen.In the electrical connection and / or connection terminal described above, the busbar has an opening for resilient engagement and electrical contacting a jumper, the above-described object is achieved in that in the jumper, a bridge rail having a rail and a plurality of connectors connected to the rail connector, the connector has two superimposed contact areas for contacting two arranged on different levels busbars of two juxtaposed connection and / or connection terminals.

Wenn zuvor ausgeführt worden ist, daß die Steckbrücke zum elektrischen Verbinden zweier nebeneinander angeordneter Anschluß- und/oder Verbindungsklemmen ausgebildet ist, so ist es zum einen natürlich möglich, mit der Steckleiste auch deutlich mehr als nur zwei Anschluß- und/oder Verbindungsklemmen miteinander zu verbinden. Zum anderen ist es nicht erforderlich, daß die miteinander elektrisch zu verbindenden Anschluß- und/oder Verbindungsklemmen unmittelbar nebeneinander angeordnet sind. Insbesondere ist es auch möglich, bei einer Mehrzahl von auf einer Tragschiene aufgerasteten Reihenklemmen, nur einige bestimmte, beispielsweise die erste, dritte, vierte, siebte und zehnte Reihenklemme durch eine entsprechend ausgebildete Steckbrücke miteinander zu verbinden. Bei einer derartigen Steckbrücke sind dann die Abstände zwischen den einzelnen Stecker entsprechend ausgebildet, was vorzugsweise dadurch realisiert werden kann, daß die zu den Reihenklemmen, die nicht miteinander elektrisch verbunden werden sollen, korrespondierenden Stecker entfernt werden, wozu im Übergangsbereich zwischen der Schienenleiste und den einzelnen Steckern entsprechende Sollbruchstellen vorgesehen sind.If it has previously been stated that the jumper for electrically connecting two juxtaposed connection and / or connection terminals is formed, it is, of course, possible to connect with the connector also significantly more than just two connection and / or connection terminals with one another , On the other hand, it is not necessary that the connecting and / or connecting terminals to be electrically connected to each other are arranged directly next to each other. In particular, it is also possible to connect only a few specific, for example, the first, third, fourth, seventh and tenth terminal block by a correspondingly formed jumper in a plurality of latched on a mounting rail terminal blocks. In such a jumper then the distances between the individual connectors are formed accordingly, which can preferably be realized in that the corresponding to the terminal blocks, which are not to be electrically connected, corresponding plug are removed, including in the transition region between the rail and the individual Plugs corresponding predetermined breaking points are provided.

Im einzelnen gibt es nun eine Vielzahl von Möglichkeiten, die erfindungsgemäße Steckbrücke bzw. die erfindungsgemäße elektrische Anschluß- und/oder Verbindungsklemme auszugestalten und weiterzubilden. Hierzu wird sowohl auf die dem Patentanspruch 1 nachgeordneten Patentansprüche als auch auf die nachfolgende Beschreibung bevorzugter Ausführungsbeispiele in Verbindung mit der Zeichnung verwiesen.

Die Figuren zeigen jeweils eine Steckbrücke 1 zum federnden Eingreifen in Öffnungen 2, die in Stromschienen 3, 30 von - hier nicht dargestellten - elektrischen Reihenklemmen ausgebildet sind. Jede Stromschiene 3, 30 ist dabei in einem Gehäuse der elektrischen Reihenklemme angeordnet und dient zum elektrisch leitenden Verbinden von zwei Anschlußelementen der Reihenklemme. Bei der Stromschiene 3 handelt es sich dabei um eine solche, die typischerweise in Reihenklemmen mit Zugfederklemmen verwendet wird, während es sich bei der Stromschiene 30 um eine solche Stromschiene handelt, die in Reihenklemmen mit Schraubklemmen verwendet wird.The figures each show a jumper 1 for resilient engagement in openings 2, which are formed in busbars 3, 30 of - not shown here - electrical terminal blocks. Each busbar 3, 30 is arranged in a housing of the electrical terminal block and serves for the electrically conductive connection of two terminal elements of the terminal block. The bus bar 3 is one typically used in terminal blocks with spring-loaded terminals, while the bus bar 30 is one such bus bar used in terminal blocks with screw terminals.

Die Steckbrücke 1 weist eine kammartig ausgebildete Brückenschiene auf, die eine obere Schienenleiste 5 (Fig. 7.) und eine Mehrzahl von mit der Schienenleiste 5 verbundenen Steckern 6 aufweist. Im den dargestellten Ausführungsbeispielen sind pro Brückenschiene 4 lediglich zwei Stecker 6 dargestellt, so daß mit den dargestellten Steckbrücken 1 auch nur zwei Stromschienen 3, 30 zweier Reihenklemmen elektrisch verbunden werden können. Es versteht sich, daß selbstverständlich auch weit mehr als zwei Stecker vorgesehen sein können.The jumper 1 has a comb-like bridge rail which has an upper rail strip 5 (FIG. Fig. 7 .) And a plurality of connected to the rail bar 5 6 plugs. In the illustrated embodiments, only two plugs 6 are shown per bridge rail 4, so that with the jumpers 1 shown, only two busbars 3, 30 of two terminal blocks can be electrically connected. It is understood that, of course, far more than two plugs can be provided.

Bei den Ausführungsbeispielen gemäß den Fig. 1 bis 3 weist jeder Stecker 6 zwei separate Kontaktschenkel 7, 8 auf. Im Unterschied dazu weist bei den Ausführungsbeispielen gemäß den Fig. 4 bis 6 jeder Stecker 6 drei Kontaktschenkel 7, 8, 9 auf. Weisen die Stecker 6 der Steckbrücken 1 nur zwei Kontaktschenkel 7, 8 auf, so sind vorzugsweise beide Kontaktschenkel 7, 8 federnd ausgebildet. Weisen die Stecker 6 dagegen drei Kontaktschenkel 7, 8, 9 auf, so ist vorzugsweise lediglich der mittlere Kontaktschenkel 9 federnd ausgebildet, während die beiden äußeren Kontaktschenkel 7, 8 relativ steif ausgebildet sind.In the embodiments according to the Fig. 1 to 3 each plug 6 has two separate contact legs 7, 8. In contrast, in the embodiments according to the 4 to 6 each plug 6 three contact legs 7, 8, 9 on. Assign the plug 6 of the jumpers 1 only two contact legs 7, 8, so preferably both contact legs 7, 8 are resilient. If, however, the plugs 6 have three contact legs 7, 8, 9, then preferably only the middle contact leg 9 is resilient formed while the two outer contact legs 7, 8 are relatively stiff.

Allen Steckern 6 bzw. allen Steckbrücken 1 ist gemeinsam, daß sie zwei übereinander angeordnete Kontaktbereiche 10, 11 aufweisen, so daß die Möglichkeit besteht, zwei auf unterschiedlichen Ebenen I, II angeordnete Stromschienen 3, 30 zweier nebeneinander angeordneter Reihenklemmen elektrisch miteinander zu verbinden. Beim Einstecken der Stecker 6 bzw. der Kontaktschenkel 7, 8, 9 in die Öffnungen 2 der Stromschienen 3, 30 kontaktieren die Stecker 6 in Längsrichtung L der Schienenleiste 5. Dabei verläuft die Längsrichtung L der Schienenleiste 5 bzw. der Steckbrücke 1 etwa senkrecht zur Längsrichtung der Stromschienen 3, 30.All plugs 6 and all jumpers 1 have in common that they have two superimposed contact areas 10, 11, so that there is the possibility of two at different levels I, II arranged busbars 3, 30 of two juxtaposed terminal blocks to electrically connect with each other. When plug 6 or the contact legs 7, 8, 9 in the openings 2 of the busbars 3, 30 contact the connector 6 in the longitudinal direction L of the rail bar 5. In this case, the longitudinal direction L of the rail bar 5 and the jumper 1 is approximately perpendicular to Longitudinal direction of the busbars 3, 30.

Die zuvor beschriebene Richtung der durch die Stecker 6 auftretenden Federkräfte beim Einstecken der Stecker 6 in die Öffnungen 2 wird dadurch erreicht, daß die Stecker 6 im unbelasteten Zustand, d. h. im nicht eingesteckten Zustand, eine Breite aufweisen, die größer als die Breite der Öffnung 2 ist. Dies wird dadurch erreicht, daß die Kontaktschenkel 7, 8, 9 im unbelasteten Zustand in Längsrichtung L geringfügig zueinander versetzt sind. Bei dem Ausführungsbeispiel gemäß den Fig. 4 bis 6 ist lediglich der mittlere Kontaktschenkel 9 in Längsrichtung L der Schienenleiste 5 geringfügig versetzt zu den beiden äußeren Kontaktschenkeln 7, 8 angeordnet. Dadurch wird erreicht, daß beim Einstecken des Steckers 6 in die Öffnung 2 der Stromschienen 3, 30 lediglich der mittlere Kontaktschenkel 9 ausgelenkt wird, wodurch eine Verwindung der Steckbrücke 1 senkrecht zur Längsrichtung L verhindert wird. Somit erleichtert sich das Einstecken einer Steckbrücke 1 mit einer Mehrzahl von Steckern 6 in eine entsprechende Anzahl von Reihenklemmen.The above-described direction of the spring forces occurring through the plug 6 when inserting the plug 6 in the openings 2 is achieved in that the plug 6 in the unloaded state, ie in the non-inserted state, have a width which is greater than the width of the opening. 2 is. This is achieved in that the contact legs 7, 8, 9 in the unloaded state in the longitudinal direction L are slightly offset from each other. In the embodiment according to the 4 to 6 is only the middle contact leg 9 in the longitudinal direction L of the rail strip 5 slightly offset from the two outer contact legs 7, 8 are arranged. This ensures that when inserting the plug 6 in the opening 2 of the busbars 3, 30 only the middle contact leg 9 is deflected, whereby a distortion of the jumper 1 is prevented perpendicular to the longitudinal direction L. Thus, the insertion of a jumper 1 with a plurality of plugs 6 facilitates in a corresponding number of terminal blocks.

Die Ausführungsbeispiele gemäß den Fig. 1 bis 3 unterscheiden sich durch die Verwendung der jeweils identischen Steckbrücke 1 zusammen mit unterschiedlichen Stromschienen 3, 30, d. h. durch die Verwendung bei unterschiedlichen Reihenklemmen. Bei dem Ausführungsbeispiel gemäß Fig. 1 ist der - in der Zeichenebene - vordere Stecker 6 in eine Öffnung 2 einer Stromschiene 3 einer Reihenklemme mit Zugfederklemmen eingesteckt, während der - in der Zeichenebene - hintere Stecker 6 in eine Öffnung 2 einer Stromschiene 30 einer Reihenklemme mit Schraubklemmen eingesteckt ist. Die Stromschiene 3 befindet sich dabei auf einer unteren Ebene I, während sich die Stromschiene 30 auf einer oberen Ebene II befindet. Somit wird die Stromschiene 3 im unteren Kontaktbereich 10 des einen Steckers 6 der Steckbrücke 1 kontaktiert, während die Stromschiene 30 im oberen Kontaktbereich 11 des zweiten Steckers 6 der Steckbrücke 1 kontaktiert wird.The embodiments according to the Fig. 1 to 3 differ by the use of each identical jumper 1 together with different busbars 3, 30, ie by the use of different terminal blocks. In the embodiment according to Fig. 1 is the - in the drawing plane - front plug 6 inserted into an opening 2 of a busbar 3 of a terminal with spring clips, while - in the drawing plane - rear plug 6 is inserted into an opening 2 of a busbar 30 a terminal with screw terminals. The Busbar 3 is located on a lower level I, while the busbar 30 is located on an upper level II. Thus, the busbar 3 is contacted in the lower contact region 10 of a plug 6 of the jumper 1, while the busbar 30 is contacted in the upper contact region 11 of the second connector 6 of the jumper 1.

Bei dem in Fig. 2 dargestellten zweiten Ausführungsbeispiel erfolgt im Unterschied dazu bei dem - in der Zeichenebene - vorderen Stecker 6 die Kontaktierung der Stromschiene 30 im oberen Kontaktbereich 11, während bei dem - in der Zeichenebene - hinteren Stecker 6 in die Kontaktierung der Stromschiene 3 im unteren Kontaktbereich 10 erfolgt.At the in Fig. 2 In contrast to this, in the drawing plane, the front connector 6 is contacted with the busbar 30 in the upper contact region 11, whereas in the drawing plane, the rear connector 6 is made in the contacting of the busbar 3 in the lower contact region 10.

Bei der in den Fig. 1 bis 3 gezeigten Steckbrücke 1 ist der - in der Zeichenebene - vordere Stecker 6 etwas schmaler als der hintere Stecker 6, da bei den dort gezeigten Ausführungsbeispielen jeweils die vordere Stromschiene 3, 30 ebenfalls schmaler als die hintere Stromschiene 30, 3 ist. Die Breite der Stekker 6 ist dabei immer auf die Breite der Öffnung 2 in der Stromschiene 3, 30 abgestimmt. Da die unterschiedlichen Reihenklemmen nur eine begrenzte Anzahl an unterschiedlichen Stromschienenbreiten aufweisen, sind insgesamt nur wenige Steckbrücken 1 mit unterschiedlichen Kombinationen von Steckerbreiten erforderlich, um nahezu alle Typen von unterschiedlichen Reihenklemmen miteinander verbinden zu können.In the in the Fig. 1 to 3 shown jumper 1 is the - in the plane of the drawing - front plug 6 slightly narrower than the rear connector 6, since in the embodiments shown there, the front busbar 3, 30 is also narrower than the rear busbar 30, 3. The width of the plug 6 is always matched to the width of the opening 2 in the busbar 3, 30. Since the different terminal blocks have only a limited number of different busbar widths, a total of only a few jumpers 1 with different combinations of connector widths are required to connect almost all types of different terminal blocks with each other.

In den Fig. 3 bis 5 sind Ausführungsbeispiele dargestellt, bei denen die Stromschienen 3, 30 jeweils beide mit den Steckern 6 im unteren Kontaktbereich 10 oder beide mit den Steckern 6 im oberen Kontaktbereich 11 kontaktieren. Insgesamt wird somit dadurch, daß jeder Stecker 6 zwei übereinander angeordnete Kontaktbereiche 10, 11 aufweist die Möglichkeit geschaffen, unterschiedliche Stromschienen 3, 30 und damit unterschiedliche Reihenklemmentypen durch die Steckbrücke 1 miteinander elektrisch zu verbinden.In the Fig. 3 to 5 Embodiments are shown in which the busbars 3, 30 each contact both the plugs 6 in the lower contact region 10 or both with the plugs 6 in the upper contact region 11. Overall, therefore, the fact that each plug 6 two superimposed contact areas 10, 11 has created the possibility, different busbars 3, 30 and thus different types of terminal blocks through the jumper 1 to electrically connect with each other.

In der Fig. 7 ist erkennbar, daß zumindest der mittlere Kontaktschenkel 9 einen Längsschlitz 12 aufweist. Der Längsschnitt 12 erstreckt sich dabei von einem Bereich etwas oberhalb des unteren Kontaktbereichs 10 bis zu einem Bereich etwas oberhalb des oberen Kontaktbereichs 11. Durch die Ausbildung des Schlitzes 12 in dem Kontaktschenkel 9 wird die Rückstellkraft des Kontaktschenkels 9 etwas verringert, wodurch die erforderliche Kraft beim Durchstecken des Steckers 6 durch die Öffnung 2 einer Stromschiene 30 in der oberen Ebene II verringert wird. Bei einer entsprechenden Dimensionierung des Längsschlitzes 12 kann dadurch eine Einsteckkraft erreicht werden, die im wesentlichen konstant ist, unabhängig davon, ob ein Stecker 6 in eine Öffnung 2 einer Stromschiene 3 in der unteren Ebene I oder in eine Öffnung 2 einer Stromschiene 30 in der oberen Ebene II eingesteckt wird.In the Fig. 7 it can be seen that at least the middle contact leg 9 has a longitudinal slot 12. The longitudinal section 12 extends from a region slightly above the lower contact region 10 to a region slightly above the upper contact region 11. The formation of the slot 12 in the contact leg 9, the restoring force of the contact leg 9 slightly reduced, whereby the force required when inserting the plug 6 through the opening 2 of a bus bar 30 in the upper level II is reduced. With a corresponding dimensioning of the longitudinal slot 12, an insertion force can thereby be achieved, which is substantially constant, regardless of whether a plug 6 in an opening 2 of a busbar 3 in the lower level I or in an opening 2 of a busbar 30 in the upper Level II is inserted.

Die Kontaktschenkel 7, 8, 9 sind derart ausgebildet, daß ihre Breite B größer als ihre Dicke D ist. Dadurch kann zum einen eine relativ schmale Steckbrükke 1 realisiert werden, ergeben sich zum anderen ausreichend große Federkräfte bei einer Belastung der Kontaktschenkel 7, 8, 9 in Längsrichtung L der Schienenleiste 5, so daß eine ausreichende Kontaktkraft gewährleistet ist. Um das Einstecken der Stecker 6 in die Öffnungen 2 der Stromschienen 3, 30 zu erleichtern, weisen die Kontaktschenkel 7, 8, 9 unterhalb des unteren Kontaktbereichs 10 an mindestens einer Schmalseite eine Auflaufschräge 13 auf.The contact legs 7, 8, 9 are formed such that their width B is greater than their thickness D. As a result, on the one hand, a relatively narrow plug-in bridge 1 can be realized, on the other hand sufficiently large spring forces at a load of the contact legs 7, 8, 9 in the longitudinal direction L of the rail strip 5, so that a sufficient contact force is ensured. In order to facilitate the insertion of the plug 6 in the openings 2 of the busbars 3, 30, the contact legs 7, 8, 9 below the lower contact portion 10 on at least one narrow side of a run-on slope 13.

Wie insbesondere in der Fig. 6b zu erkennen ist, besteht die Brückenschiene 4 einer Steckbrücke 1 aus drei parallel zueinander angeordneten Brückenschienenabschnitten 14, 15, 16, die jeweils im wesentlichen identisch aufgebaut sind, nämlich einen Schienenleistenabschnitt 17 und jeweils zwei mit dem Schienenleistenabschnitt 17 verbundene Kontaktschenkel 7, 8, 9 aufweisen. Um bei der Verbindung der einzelnen Brückenschienenabschnitten 14, 15, 16 eine genaue Positionierung und eine sichere Halterung zu gewährleisten, sind die aneinander anliegenden Brückenschienenabschnitte 14, 15, 16 formschlüssig zusammengehalten. Hierzu weisen die einzelnen Brückenschienenabschnitte 14, 15, 16 jeweils Zapfen und korrespondierende Bohrungen 18 auf, in die die Zapfen einer anliegenden Brückenschiene 14, 15 eingreifen.As in particular in the Fig. 6b can be seen, there is the bridge rail 4 a jumper 1 of three mutually parallel bridge rail sections 14, 15, 16, each of which is constructed substantially identical, namely a rail strip section 17 and two each with the rail strip section 17 connected contact legs 7, 8, 9 , In order to ensure an accurate positioning and a secure support in the connection of the individual bridge rail sections 14, 15, 16, the adjoining bridge rail sections 14, 15, 16 are held together in a form-fitting manner. For this purpose, the individual bridge rail sections 14, 15, 16 each have pins and corresponding bores 18 into which the pins of an adjoining bridge rail 14, 15 engage.

Zur zusätzlichen Sicherung der Verbindung der einzelnen Brückenschienenabschnitte 14, 15, 16 und zur elektrischen Isolierung weist die Steckbrücke 1 einen die Schienenleiste 5 übergreifenden Isolierkopf 19 auf. In dem Isolierkopf 19, der reibschlüssig auf der Schienenleiste 5 aufsitzt, ist eine in Längsrichtung L verlaufende Ausnehmung 20 vorgesehen, die zum Herausziehen bzw. Entrasten der Steckleiste 1 mit Hilfe der Spitze eines Schraubendrehers dienen kann.To additionally secure the connection of the individual bridge rail sections 14, 15, 16 and for electrical insulation, the jumper 1 has a rail bar 5 cross-head insulating 19. In the insulating head 19, which is frictionally seated on the rail 5, a running in the longitudinal direction L recess 20 is provided which can serve for pulling or unlatching of the connector 1 by means of the tip of a screwdriver.
