Description

Verbindungselement und Querbrückeneinrichtung für elektrische Klemmen  Connecting element and cross-bridge device for electrical terminals
Die vorliegende Erfindung betrifft ein Verbindungselement, angepasst und eingerichtet zum Anschließen eines elektrischen Leiters an eine Stromschiene einer elektrischen Klemme über deren Brückenschacht, umfassend ein zum streckbaren Kontaktieren der Stromschiene durch Einführen in den Brückenschacht eingerichtetes Kontaktfußelement mit einem Leiteranschlusselement, wobei das Kontaktfußelement mit dem Leiteranschlusselement elektrisch leitend verbunden ist. Des Weiteren betrifft die vorliegende Erfindung eine Querbrückeneinrichtung zum elektrischen Verbinden der Stromschienen von elektrischen Klemmen, umfassend mindestens einen elektrischen Leiter mit jeweils an dessen Leiterenden angeordneten Verbindungselementen. Derartige Verbindungselemente bzw. Querbrückeneinrichtungen sind aus dem Stand der Technik bereits bekannt. Die bekannten Verbindungselemente sind beispielsweise als Prüfstecker ausgebildet, die in den Brückenschacht elektrischer Klemmen eingesteckt werden, um mit der Stromschiene der jeweiligen elektrischen Klemme einen leitenden Kontakt herzustellen. Des Weiteren sind Querbrückeneinrichtungen bekannt, die auch als Querverbinder oder Steckbrücker bezeichnet werden, um eine elektrisch leitende Verbindung zwischen den jeweiligen Stromschienen mindestens zweier elektrischer Klemmen herzustellen. Solche Klemmen sind üblicherweise als Reihen-, An- schluss- und/oder Verbindungsklemmen ausgebildet. Die elektrischen Klemmen verfügen über einen Brückenschacht, der häufig auch als Funktionsschacht bezeichnet wird. Über den Brücken- bzw. Funktionsschacht kann die jeweilige Stromschiene der elektrischen Klemme mit dem eingangs beschriebenen Verbindungselement durch Einstecken desselben auf einfache Weise kontaktiert werden. Mittels der bekannten Querbrückeneinrichtung ist es möglich, eine oder mehrere der Stromschienen der elektrischen Klemmen untereinander zu verbinden. The present invention relates to a connecting element, adapted and arranged for connecting an electrical conductor to a busbar of an electrical terminal via the bridge shaft, comprising a contact foot for a stretchably contacting the busbar by insertion into the bridge shaft arranged Kontaktfußelement with a conductor connecting element, the Kontaktfußelement with the conductor connecting element electrically is conductively connected. Furthermore, the present invention relates to a cross-bridge device for electrically connecting the busbars of electrical terminals, comprising at least one electrical conductor, each with arranged at the conductor ends connecting elements. Such connecting elements or transverse bridge devices are already known from the prior art. The known connecting elements are formed, for example, as a test plug, which are inserted into the bridge shaft electrical terminals to make a conductive contact with the busbar of the respective electrical terminal. Furthermore, cross-bridge devices are known, which are also referred to as cross-connector or jumper to produce an electrically conductive connection between the respective busbars of at least two electrical terminals. Such terminals are usually designed as series, connection and / or connection terminals. The electrical terminals have a bridge shaft, which is often referred to as a function shaft. About the bridge or functional shaft, the respective busbar of the electrical terminal with the connection element described above by plugging the same can be contacted in a simple manner. By means of the known transverse bridge device, it is possible to connect one or more of the busbars of the electrical terminals with each other.
Eine solche Querbrückeneinrichtung für eine elektrische Klemme ist beispielsweise aus dem Dokument WO 2012/130825 A2 bekannt. Die bekannte Querbrückeneinrichtung umfasst einen Kopfteil mit mindestens zwei Klemmzungen, wobei die Klemmzungen über den Kopfteil elektrisch leitend miteinander verbunden sind. Durch Einstecken der Klemmzungen in den Brückenschacht der elektrischen Klemmen kommen diese mit der jeweiligen Stromschiene in Kontakt, so dass mindestens jeweils zwei der Stromschienen über die Querbrückeneinrichtung elektrisch miteinander verbunden werden. Such a transverse bridge device for an electrical terminal is known, for example, from the document WO 2012/130825 A2. The known transverse bridge device comprises a head part with at least two clamping tongues, wherein the clamping tongues are electrically conductively connected to one another via the head part. By inserting the clamping tongues into the bridge shaft of the electrical terminals they come with the respective busbar in contact, so that at least two of the busbars are electrically connected to each other via the cross-bridge device.
Nachteilig ist, dass der Abstand der Kontaktzungen unveränderbar festgelegt ist, so dass für verschiedene zu überbrückende Abstände zwischen jeweils zwei elektrischen Klemmen jeweils eine speziell angefertigte Querbrückeneinrichtung benötigt wird. Um jeden Anwendungsfall abdecken zu können, ist es daher erforderlich, eine Vielzahl von Querbrückeneinrichtungen unterschiedlicher Geometrie vorzuhalten. Es ist daher Aufgabe der vorliegenden Erfindung ein Verbindungselement sowie eine entsprechende Querbrückeneinrichtung vorzuschlagen, die bei möglichst einfacher Bauart zugleich ein Höchstmaß an Flexibilität in der Anwendung gewährleistet. The disadvantage is that the distance of the contact tongues is fixed unchangeable, so that in each case a specially made cross-bridge device is required for different bridged distances between each two electrical terminals. In order to cover each application, it is therefore necessary to maintain a variety of cross-bridge devices of different geometry. It is therefore an object of the present invention to provide a connecting element and a corresponding cross-bridge device, which ensures the simplest possible design at the same time a maximum of flexibility in the application.
Die Aufgabe wird durch das eingangs genannte Verbindungselement dadurch gelöst, dass das Leiteranschlusselement zur Aufnahme und Kontaktierung des elektrischen Leiters unter elastischer Verformung des elektrischen Leiters eingerichtet und ausgebildet ist. Auf diese Weise wird ein Verbindungselement bereitgestellt, mittels dessen mit einem elektrischen Leiter bzw. dessen Leiterende eine nur bedingt lösbare elektrische Verbindung auf einfache Art und Weise hergestellt wird. So wird zu jeder Zeit ein zuverlässiger mechanischer und elektrischer Kontakt zwischen dem Leiteranschlusselement und dem elektrischen Leiter gewährleistet. Durch Einstecken des Verbindungselements in den Brückenschacht der elektrischen Klemme wird auf diese Weise eine elektrische Verbindung zwischen dem elektrischen Leiter und der Stromschiene der elektrischen Klemme hergestellt. Das Leiteranschlusselement ist vorzugsweise zur Ausbildung einer Crimp-Verbindung mit dem elektrischen Leiter ausgebildet und eingerichtet. Die mechanische und elektrische Verbindung zwischen dem elektrischen Leiter und dem Leiteranschlusselement erfolgt unter plastischer Verformung des Leiteranschlusselements und/oder des Leiterendes des elektrischen Leiters. Eine zweckmäßige Ausgestaltung der Erfindung ist dadurch gekennzeichnet, dass das Leiteranschlusselement ein zur Klemmkontaktierung des elektrischen Leiters eingerichtetes Quetschelement umfasst. Durch die Verwendung des Quetschelements ist die Verbindung zwischen dem Leiteranschlusselement und dem elektrischen Leiter auf einfache Weise herstellbar. Das Leiterende des elektrischen Leiters wird hierzu in das Quetschelement des Leiteranschlusselements eingeführt und mittels eines geeigneten Werkzeugs durch Verpressen miteinander nur bedingt lösbar verbunden. Gemäß einer weiteren bevorzugten Ausführungsform ist das Quetschelement als Quetschhülse ausgebildet. Auf diese Weise wird das Leiterende durch gleichmäßig verteilte, radial wirkende Klemmkräfte sicher mechanisch gehalten und zugleich eine zuverlässige elektrische Kontaktierung gewährleistet. Gemäß einer alternativen vorteilhaften Ausbildung der Erfindung umfasst das Leiteranschlusselement ein zur Klemmkontaktierung des elektrischen Leiters eingerichtetes Schneidklemmelement. Wie schon das Quetschelement bietet auch das Schneidklemmelement den Vorzug einer nur bedingt wieder lösbaren Verbindung. Zur Vermeidung von Wiederholungen verwei- sen wir daher auf die in diesem Zusammenhang vorgenannten Vorteile. The object is achieved by the connection element mentioned above in that the conductor connection element for receiving and contacting the electrical conductor is set up and designed with elastic deformation of the electrical conductor. In this way, a connecting element is provided, by means of which an electrical conductor or its conductor end a conditionally releasable electrical connection is made in a simple manner. Thus, a reliable mechanical and electrical contact between the conductor connection element and the electrical conductor is ensured at all times. By inserting the connecting element into the bridge shaft of the electrical terminal, an electrical connection between the electrical conductor and the busbar of the electrical terminal is produced in this way. The conductor connection element is preferably designed and set up to form a crimp connection with the electrical conductor. The mechanical and electrical connection between the electrical conductor and the conductor connection element takes place with plastic deformation of the conductor connection element and / or the conductor end of the electrical conductor. An expedient embodiment of the invention is characterized in that the conductor connection element comprises a crimping element designed for terminal contacting of the electrical conductor. By the use of the crimping element, the connection between the conductor connection element and the electrical conductor can be produced in a simple manner. For this purpose, the conductor end of the electrical conductor is inserted into the crimping element of the conductor connection element and connected to one another only to a limited extent by means of a suitable tool by pressing together. According to a further preferred embodiment, the squeezing element is designed as a ferrule. In this way, the conductor end is securely held mechanically by uniformly distributed, radially acting clamping forces while ensuring a reliable electrical contact. According to an alternative advantageous embodiment of the invention, the conductor connection element comprises an insulation displacement contact element arranged for the clamping contact of the electrical conductor. Like the crimping element, the insulation displacement element also has the advantage of a connection that can only be released again to a limited extent. To avoid repetition, we therefore refer to the advantages mentioned above.
Gemäß einer vorteilhaften Weiterbildung der Erfindung umfasst das Schneidklemmelement mindestens zwei einen Leiterklemmschlitz bildende Kontaktelemente. Der elektrische Leiter bzw. dessen Leiterende wird in dem Leiterklemmschlitz von den bei- den Kontaktelementen gehalten und zugleich elektrisch kontaktiert. Der elektrische Leiter kann so auf besonders einfache Weise an die erfindungsgemäße Verbindungseinrichtung angeschlossen werden. According to an advantageous embodiment of the invention, the insulation displacement element comprises at least two contact elements forming a conductor clamping slot.

Eine weitere zweckmäßige Ausgestaltung der Erfindung sieht vor, dass das Kontakt- fußelement mindestens zwei einen Stromschienenklemmschlitz bildende Klemmzungen aufweist, die eingerichtet sind, das Kontaktfußelement mittels Klemmkontaktierung mit der Stromschiene der Klemme zu verbinden. Dies bietet den Vorteil, dass die erfindungsgemäße Verbindungseinrichtung durch einfaches Einstecken in den Brückenschacht der elektrischen Klemme mit dieser verbunden, also eine elektrische Kontak- tierung der Stromschiene der elektrischen Klemme erzielt wird. Durch Aufbringen einer Lösekraft, die gegenüber der zum Einstecken der Verbindungseinrichtung in den Brückenschacht erforderlichen Steckkraft entsprechend größer ist, ist es möglich, die Verbindung zu der elektrischen Klemme wieder zu lösen und die erfindungsgemäße Verbindungseinrichtung aus dem Brückenschacht zu entfernen.

Die erfindungsgemäße Querbrücken- einrichtung umfasst mindestens einen elektrischen Leiter 33 mit jeweils an dessen Leiterenden angeordneten Verbindungselementen 10. Die Verbindungselemente 10 sind vorteilhafterweise wie zuvor beschrieben ausgebildet und eingerichtet. Mit anderen Worten ist es mittels der erfindungsgemäßen Verbindungselemente 10 möglich, auf besonders einfache Weise Querbrückeneinrichtungen zum Verbinden der Stromschie- nen von elektrischen Klemmen beliebiger Länge frei zu konfektionieren. Hierzu werden die jeweiligen Leiterenden eines elektrischen Leiters 33 jeweils mit einem Verbindungselement 10 versehen, in dem diese durch Quetschen bzw. Crimpen an den Leiterenden angeordnet werden. In der Fig. 4 ist eine perspektivische Ansicht des erfindungsgemäßen Querbrückenele- ments mit einem der Verbindungselemente 10 entsprechend der ersten Ausführungsform beispielhaft gezeigt. Mittels des erfindungsgemäßen Verbindungselements 10 ist es so möglich, auf besonders einfache Weise die Stromschienen von elektrischen Klemmen miteinander elektrisch zu verbinden. Die abisolierten Leiterenden eines elek- trischen Leiters 33 beliebiger Länge werden hierzu jeweils mit einem der Verbindungselemente 10 versehen, indem die Leiterenden jeweils in der Leitereinführrichtung 14 in die jeweiligen Leiteranschlusselemente 12 eingeführt und dort unter Ausbildung einer Quetsch- bzw. Crimpverbindung angeordnet werden. Auf diese Weise lassen sich die erfindungsgemäßen Querbrückeneinrichtungen mit verschiedenen Leitungslängen kun- denspezifisch herstellen. An den freien Enden der beiden in Fig. 4 gezeigten Enden - wie jedoch aus Fig. 4 nicht hervorgeht - ist jeweils eines der Verbindungselemente 10 angeordnet. The present invention is further characterized by a - not shown in the drawing - cross-bridge device, which is adapted for electrically connecting the busbars of electrical terminals. The transverse bridge device according to the invention comprises at least one electrical conductor 33, each with connecting elements 10 arranged at its conductor ends. The connecting elements 10 are advantageously constructed and arranged as described above.

For this purpose, the respective conductor ends of an electrical conductor 33 are each provided with a connecting element 10, in which they are arranged by crimping or crimping at the conductor ends. 4 shows a perspective view of the transverse bridge element according to the invention with one of the connecting elements 10 according to the first embodiment by way of example. By means of the connecting element 10 according to the invention, it is possible to electrically connect the busbars of electrical terminals with each other in a particularly simple manner. For this purpose, the stripped conductor ends of an electrical conductor 33 of any length are each provided with one of the connecting elements 10 by inserting the conductor ends into the respective conductor connecting elements 12 in the conductor insertion direction 14 and arranging them there to form a crimp or crimp connection.

Die erfindungsgemäßen Verbindungselemente 10 bieten den Vorteil, dass kundenbe- darfsspezifisch die erfindungsgemäßen Querbrückeneinrichtungen hinsichtlich deren Leitungsquerschnitte sowie der gewünschten Länge hergestellt werden können. Hierzu wird der elektrische Leiter 33 entsprechend des Bedarfs abgelängt und die Leiterenden abisoliert. Die abisolierten Leiterenden werden anschließend jeweils in der Leitereinführrichtung 14 in die Leiteranschlusselemente 12 eingeschoben und anschließend mit den bereits genannten Verfahren durch Crimpen oder Quetschen elektrisch kontaktiert und dauerhaft mit dem Verbindungselement 10 verbunden. The connecting elements 10 according to the invention offer the advantage that, according to the customer's requirements, the transverse bridge devices according to the invention can be produced with regard to their cable cross-sections and the desired length. For this the electrical conductor 33 is cut to length according to requirements and the conductor ends are stripped.

Sollen beispielsweise die Stromschienen von drei der elektrischen Klemmen miteinander elektrisch kontaktiert werden, werden zwei der elektrischen Leiter 33 benötigt, von denen jeweils eines der Leiterenden gemeinsam in eines der Leiteranschlusselemente 12 eines der Verbindungselemente 10 ein- geführt und mit diesem verbunden wird. Die beiden noch freien Leiterenden werden jeweils - in Fig. 4 nicht gezeigt - mit einem der erfindungsgemäßen Verbindungselemente 10 versehen.
