Description

Die Erfindung betrifft ein Stromschienenanordnung, gemäß Oberbegriff des Patentanspruches 1.The invention relates to a busbar arrangement, according to the preamble of claim 1.

Im Messe- und Bühnenbau werden modulare Traversensysteme verwendet, um die Raumabgrenzungen sowie Beleuchtungen, Tontechnik und Medientechnik anzubringen. Ein solches System ist auf der Webseite www.traversen-discount.com dargestellt. Das Traversensystem besteht aus einem Sortiment von ggfs verschieden langen Traversen, die dann zusammenfügbar sind und so ein gesamter Traversenaufbau vor Ort erfolgen kann. Dabei werden die elektrischen Leitungen für die Beleuchtung und/oder Akustik und/oder Medientechnik, sowie ggfs Datenleitungen gesondert mittels Kabeln verlegt, die an den Traversen befestigt werden.
Die Verlegung von Einzelkabeln ist aufwändig und oftmals auch sicherheitstechnisch nicht hinreichend. Aus sicherheitstechnischen Gründen sind solche Traversenkonstruktionen auch elektrisch zu erden.
Auch aus der wo 2010/144261 A1 ist ein so ausgeführtes Traversenssystem bekannt.In trade fair and stage construction, modular truss systems are used to install the room boundaries as well as lighting, audio engineering and media technology. Such a system is shown on the website www.traversen-discount.com . The truss system consists of an assortment of possibly different long trusses, which are then joined together and so a complete truss structure can be made on site. The electrical cables for lighting and / or acoustics and / or media technology, as well as, if necessary, data cables are laid separately by means of cables which are fastened to the trusses.
The laying of individual cables is complex and often also insufficient in terms of safety. For safety reasons, such truss constructions are also to be grounded electrically.
Also from where 2010/144261 A1 is a so executed truss system known.

Aus der US 7 819. 676 B1 ist ein Stromverteilersystem in Form einer Stromschiene bekannt. Das Gehäuse selbst ist dabei geerdet. Diese Stromschiene ist ein starres nicht modulares, sondern nur abzweigbares System, welches im Messe- und Ladenbau nicht verwendbar ist.From the US 7,819,676 B1 is a power distribution system in the form of a busbar known. The housing itself is earthed. This busbar is a rigid non-modular, but only branchable system, which is not usable in trade fair and shop fitting.

Aus dem US-Patent 5 151 043 ist eine Stromschiene bekannt, die lediglich aufsteckbare Stromkontaktelemente aufweist.From the U.S. Patent 5,151,043 is known a busbar having only attachable power contact elements.

Aus der UK 2 344 001 A ist eine Stromschiene bekannt, welche an den Enden Stecker zur elektrischen Verbindung und Verlängerung der Stromschiene aufweist. Das Gehäuse ist dabei geerdet, aber das System ist verlängerbar, aber nicht modular.From the UK 2 344 001 A a busbar is known, which has at the ends plug for electrical connection and extension of the busbar. The case is grounded, but the system is extendable but not modular.

Aus der DE 692 04 010 T2 ist eine Stromschiene bekannt, mit elektrischen Leitungen innerhalb eines längs erstreckten geschlossenen Gehäuses, wobei das Gehäuse die elektrischen Leitungen umgibt und an dessen Enden Steckkontakte angeordnet sind. Eine solche Stromschiene eignet sich zur mechanischen Befestigung an einer Traversenanordnung wie sie aus dem Messebau bekannt ist. Hierzu enthält diese Stromschiene integrierte mechanische, elektrisch leitende und geerdete, mit Schutzleiter versehene Befestigungselemente.From the DE 692 04 010 T2 a bus bar is known, with electrical lines within an elongated closed housing, wherein the housing surrounds the electrical lines and at the ends plug contacts are arranged. Such a busbar is suitable for mechanical attachment to a truss assembly as it is known from the fair construction. For this purpose, this busbar contains integrated mechanical, electrically conductive and earthed, provided with protective conductor fasteners.

Diesbezügliche Traversen für den Laden- und Messebau sind außerdem aus der DE 19938970 A1 und aus der DE 20 2004 018 016 U1 bekannt.Related traverses for shop and exhibition construction are also from the DE 19938970 A1 and from the DE 20 2004 018 016 U1 known.

Insbesondere die mechanische Befestigung von Stromschienen an Metall-Traversen bedingt aus Sicherheitsgründen, dass diese geerdet werden müssen. Hierzu sind die Traversen zusätzlich zu erden bzw eine elektrisch leitende, und einen erwartbaren maximalen Kurzschlussstrom trägfähige Verbindung zum Schutzleiter oder der Erde herzustellen. Da dies ein gesonderter Installationsschritt ist, aber von erheblicher sicherheitstechnischer Bedeutung ist, darf dieser auch im Zuge menschlichen Versagens nicht vergessen werden.In particular, the mechanical attachment of busbars to metal trusses requires for safety reasons that they must be grounded. For this purpose, the trusses are grounded in addition to an electrically conductive, and an expected maximum short-circuit current supportable connection to the protective conductor or the earth. Since this is a separate installation step, but of considerable safety significance, this must not be forgotten in the wake of human error.

Darüber hinaus ist aus der DE 20 2004 018 016 U1 bekannt, innerhalb der Traverse auch eine Stromschiene zu integrieren.In addition, from the DE 20 2004 018 016 U1 known to integrate within the crossbar and a busbar.

Dabei ist die Stromschiene oder Stromschienenanorndung in einer der sogenannten Gurtrohre derart mit integriert, dass das Gurtrohr über die gesamte Länge geschlitzt ist. Ein ganz erheblicher Nachteil resultiert aus dieser bekannten integrierten Stromschiene. Durch die Längsschlitzung ist das Rohr und mit dem auch die Traverse in ihrer Statik deutlich geschwächt.
Der Erfindung liegt die Aufgabe zugrunde, bei einer Stromschienenanordnung für die Anwendung im Messe- und Ladenbau einerseits die Kabelverlegung erheblich zu vereinfachen und anderseits die sicherheitstechnischen Aspekte zur Leistungsverteilung und Erdung mit zu berücksichtigen, ohne dabei die Statik zu schwächen.
Die gestellte Aufgabe wird bei einer Stromschiene der gattungsgemäßen Art erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Weitere vorteilhafte Ausgestaltungen sind in den abhängigen Ansprüchen angegeben.
Kern der Erfindung ist, dass die Stromschiene als elektrisches Leitungssystem für ein aus zusammensteckbaren Traversen bestehendes Traversensystem im Messe- und Ladenbau eingesetzt wird, derart, dass die Stromschiene ebenso modular und steckbar ist, wie das Traversensystem selbst, indem die elektrischen Steckkontakte der in der Traverse angeordneten und befestigten Stromschien in etwa auf derselben Ebene sind, wie die mechanischen Ankopplungsstellen der Traversen, und dass durch Befestigung der Stromschiene bzw des Stromschienengehäuses (2) an der Traverse (1) eine Zwangserdung des Traversensystems gegeben ist.
Mit der zur Traverse quasi parallel verlaufenden erfindungsgemäßen Stromschiene bzw Stromschienenanordnung wird die Statik des Traversensystems nicht geschwächt. Durch die Anordnung der Steckkontakte an den Stirnseiten ist die erfindungsgemäße Stromschiene ebenso modular und steckbar wie das Traversensystem selbst. Wesentlich ist aber die erfindungsgemäße Zwangserdung der Traverse über die Befestigungselemente zwischen Stromschiene bzw Stromschienenanordnung und Traverse. Innerhalb des Stromschienengehäuses sind die Befestigungselemente direkt geerdet, oder über eine Erdung des Stromschienengehäuses selbst. Somit ergibt sich in Lösung der Aufgabe ein modulares, einfach verlegbares Stromverteilungssystem, sowie eine sichere Erdung sowohl der Stromschiene bzw des Stromschienengehäuses der anschließbaren Verbaucher sowie der Traverse selbst. Auf diese Weise kann die sicherheitsrelevante Erdung der Traversenanordnung nie vergessen werden.The busbar or Stromschienenanorndung is integrated in one of the so-called Gurtrohre so that the Gurtrohr is slotted over the entire length. A very significant disadvantage results from this known integrated busbar. By the Longitudinal slit is the tube and with which the traverse is significantly weakened in its statics.
The invention has for its object to simplify the cable laying considerably on a hand rail arrangement for use in trade fair and shopfitting on the one hand and on the other hand, the safety aspects for power distribution and grounding with to take into account, without weakening the statics.
The stated object is achieved according to the invention in a busbar of the generic type by the characterizing features of claim 1. Further advantageous embodiments are specified in the dependent claims.
The core of the invention is that the busbar is used as an electrical line system for a truss system consisting of mating trusses in trade fairs and shopfitting, such that the busbar is as modular and pluggable, as the truss system itself by the electrical plug contacts in the crossmember arranged and fixed busbars are approximately on the same level as the mechanical coupling points of the trusses, and that by fixing the busbar or the busbar housing (2) on the crossmember (1) is given a forced earthing of the truss system.
The statics of the truss system is not weakened by the busbar or busbar arrangement according to the invention extending parallel to the crossbar. Due to the arrangement of the plug contacts on the end faces the bus bar according to the invention is just as modular and pluggable as the truss system itself. But essential is the invention Zwangderdung the crosshead on the fasteners between busbar or busbar assembly and Traverse. Inside the busbar housing are the fasteners directly grounded, or via a grounding of the busbar housing itself. Thus results in solution of the problem, a modular, easy deployable power distribution system, as well as a secure ground both the busbar or the busbar housing connectable consumers and the crossbar itself. In this way, the safety-related grounding the truss arrangement will never be forgotten.

Im Übrigen ist mit Stromschiene die Anordnung von Leiterschienen in einem Gehäuse gemeint. Üblicherweise werden solche Stromschienen auch als Stromverteilerleisten bezeichnet, und bestehen aus einem länglichen Gehäuse in dem die Leiterbahnen oder Leiterschienen oder Kabel angeordnet sind, und diese mit Steckdosenkontakten verbunden sind, die am Gehäuse einer solchen Stromverteilerleiste angeordnet sind. Die einfachste Ausführung solcher Stromverteilerleisten ist die transportable Mehrfachsteckdose.Incidentally, the term busbar means the arrangement of conductor rails in a housing. Typically, such busbars are also referred to as power distribution strips, and consist of an elongated housing in which the conductor tracks or conductor rails or cables are arranged, and these are connected to socket contacts, which are arranged on the housing of such a power distribution strip. The simplest version of such power distribution strips is the portable multiple socket.

In weiterer, ganz erheblich vorteilhafter Ausgestaltung ist angegeben, dass jede Stromschieneanordnung desIn a further, very considerably advantageous embodiment is stated that each busbar arrangement of the

Leitungssystems zusätzlich Datenleitungen enthält und dass entlang ihrer Länge auch verteilt Datensignalanschlüsse angeordnet sind. D.h. es werden auch Datenleitungen innerhalb dieser Stromschiene verlegt. Dies ist eine weitere deutliche Steigerung der Funktionalität. Die Leitungsanschlüsse sowie nunmehr auch die Datenanschlüsse können gleichermaßen durch die stirnseitig platzierten Steckkontakte von Stromschiene zu Stromschiene durchgeschleift werden. Das System ist somit sowohl für die Kraftstromverteilung als auch für die Datensignalverteilung modular.Line system additionally contains data lines and that along their length and distributed data signal terminals are arranged. This means that data lines are also laid within this busbar. This is another significant increase in functionality. The line connections and now also the data connections can equally be looped through the front-side plug contacts from busbar to busbar. The system is thus for both the power distribution as well as for the Data signal distribution modular.

In weiterer vorteilhafter Ausgestaltung ist daher angegeben, dass die Datensignalanschlüsse XLR Kontakte zur DMX-Signalübertagung, oder XLR zur ADAT-Übertragung, oder Netzwerkbuchsen RJ45, wie z.B für Artnet etc sind.In a further advantageous embodiment, it is therefore specified that the data signal connections XLR are contacts for DMX signal transmission, or XLR for ADAT transmission, or network sockets RJ45, such as for Artnet etc.

Eine weiterhin vorteilhafte Ausgestaltung ist, dass jede Stromschiene mindestens einen integrierten Signalverstärker bzw Bussignalverstärker aufweist. Auf diese Weise entsteht eine integrale komplette und modulare Lösung, bei der keinerlei externe Signalverstärker mehr nötig sind. An jeder Stelle eines so mit diesen Stromschienen ausgestatteten Traversensystems liegt auch ein pegelstarkes Datensignal vor.A further advantageous embodiment is that each bus bar has at least one integrated signal amplifier or bus signal amplifier. This creates an integral, complete and modular solution that eliminates the need for external signal amplifiers. At each point of a truss system equipped with these busbars, there is also a level-strong data signal.

In weiterer vorteilhafter Ausgestaltung ist vorgesehen, dass die Abmessungen der an den Traversen befestigten Stromschienen und der Traversen selbst so aufeinander abgestimmt sind, dass die Steckkontakte der Stromschienen beim Zusammenfügen der Traversen kontaktierend ineinandergreifen. So ist das Stromschienensystem in gleicher Weise modular wie das Traversensystem.In a further advantageous embodiment, it is provided that the dimensions of the busbars fixed to the trusses and the trusses themselves are coordinated so that the plug contacts of the busbars engage in contacting the mating of the trusses. Thus, the busbar system is modular in the same way as the truss system.

Innerhalb der Stromschiene kann Einphasen-Wechselspannung verlaufen, aber auch Dreiphasen-Wechselspannung. Bei der Dreiphasigen Lösungen werden die einzelnen Phasen dann auf die verschiedenen Niederspannungssteckverbinder wie Steckdosen bzw Anschlüsse verteilt. So ist demnach weiter ausgestaltet, dass jede Stromschiene des Leitungssystems entlang ihrer Länge verteilt angeordnete Niderspannungssteckverbinder wie Schutzkontaktsteckdosen, oder CEE- oder Powercon- oder Hartinganschlüsse enthält.Within the busbar can run single-phase AC voltage, but also three-phase AC voltage. In the case of the three-phase solutions, the individual phases are then distributed to the various low-voltage connectors such as sockets or connections. Thus, it is further configured such that each busbar of the line system distributed along its length arranged Niderspannungssteckverbinder as earthed sockets, or contains CEE or Powercon or Hartinganschlüsse.

In weiterer vorteilhafter Ausgestaltung ist angegeben, dass jede Stromschiene zusätzlich zur externen Einspeiseabsicherung in die Stromschiene integrierte Sicherungsautomaten zur Einzel-Absicherung der Niederspannungssteckverbinder bspw der Schutzkontaktsteckdosen enthält. Auf diese Weise ist JEDE EINZELNE Steckdose lastmäßig limitierbar, so dass sichergestellt werden kann, dass die Stromtragfähigkeit der Steckdose selbst, sowie der in der Stromschiene selbst verlaufenden Hauptleitungen durch ein Vielzahl von aktiv BETRIEBENEN Steckendosen nicht überlastet werden kann. Diese Gesamtabsicherung erfolgt dann zusätzlich noch über die externe Einspeiseabsicherung. Dies ist ebenfalls ein wesentliches Sicherheitsmerkmal, was in herkömmlichen Stromschienen so in dieser Form gar nicht zu finden ist.In a further advantageous embodiment, it is stated that each busbar contains in addition to the external feed-in protection in the busbar integrated circuit breakers for individual protection of low-voltage connectors bspw the grounded sockets. In this way, EVERY SINGLE socket load is limited, so that it can be ensured that the current carrying capacity of the socket itself, as well as running in the busbar itself main lines can not be overloaded by a variety of actively operated sockets. This total protection then takes place additionally via the external feed-in protection. This is also an essential safety feature, which is not to be found in conventional busbars in this form.

Die oben genannte Ausführung wird somit so ermöglicht, indem die Absicherungsleistungen der Sicherungsautomaten jeweils so bemessen sind, dass diese kleiner oder gleich der gewünschten Stromtragfähigkeit der jeweiligen Kraftstromanschlüsse (Steckdosen) sind. Dies erscheint zwar trivial, ist in diesem sehr speziellen Anwendungsfall aber von besonderer Bedeutung.The above-mentioned embodiment is thus made possible by the hedging services of the circuit breakers are each dimensioned so that they are less than or equal to the desired current carrying capacity of the respective power connections (sockets). Although this seems trivial, it is of particular importance in this very special application.

Schließlich ist das System noch schutznormmäßig ausgestaltet, derart dass die Kontakte des Leitungssystems sowie die Stromschienenanordnung selbst staub- und spritzwasser-geschützt nach IP 44 ausgeführt sind.Finally, the system is still configured as standard protection, so that the contacts of the pipe system and the busbar arrangement itself dust and splash water protected are designed according to IP 44.

The busbar includes a longitudinally extending housing 2 are arranged in the conductor tracks as conductor rails, which are not shown here. For 1-phase alternating current, these are the phase L, the neutral N and the grounding line.

Bei 3-Phasen-Wechselstrom sind dies die Phasen L1, L2 und L3, sowie der Nulleiter und der Erdungsleiter.
Im letztgenannten Fall können die drei Phasen auf verschiedene Steckdosen unterverteilt werden.
Die hier dargestellte Stromschiene 2 ist Teil eines modularen Systems vieler Stromschienen, die in der beschriebenen Weise zuerst an die Traversen 1 befestigt werden und dann zusammen mit den Traversen 1 zu einem Traversensystem aufgebaut (zusammengefügt) werden.
Die Traverse besteht in diesem Beispiel aus vier sogenannten Gurtrohren. Diese sind mit hier aus Übersichtsgründen nicht weiter dargestellten Querträgern oder einen Art Fachwerk miteinander verbunden und verstrebt.
Die Stromschiene 2 unten wird von der dortig dargestellten Position quasi nach oben gedreht und zwischen die Gurtrohre geschoben. An einem hier dargestellten Querrohr 1' wird dann das Befestigunsgelement 5 und am anderen Ende der Stromschiene entsprechend mit dem Befestigungselement 4 eine mechanische Verbindung hergestellt.In 3-phase alternating current, these are the phases L1, L2 and L3, as well as the neutral conductor and the grounding conductor.
In the latter case, the three phases can be subdivided into different sockets.
The busbar 2 shown here is part of a modular system of many busbars, which are first attached to the trusses 1 in the manner described and then built together with the trusses 1 to a truss system (assembled).
The traverse consists in this example of four so-called harness tubes. These are interconnected and braced with here for reasons of clarity not shown cross members or a kind of framework.
The busbar 2 below is rotated from the position shown there quasi upwards and pushed between the Gurtrohre. At a cross tube 1 'shown here then the Befestigungsigunsgelement 5 and at the other end of the busbar according to the fastener 4 made a mechanical connection.

Die Stromschiene 2 ist dann in der hier gestrichtelt dargestellten Position innerhalb der Traverse 1 angeordnet und befestigt. Dabei liegen die elektrischen Steckkontakte in etwa auf derselben Ebene wie die mechanischen Ankopplungstellen der Traversen miteinander.The busbar 2 is then arranged in the position shown here gestrichtelt within the cross member 1 and fixed. The electrical plug contacts are approximately at the same level as the mechanical coupling points of the trusses with each other.

Die Stromschiene 2 wird dabei über die Befestigungselemente 4 und 5 mit der jeweiligen Traverse 1 verbunden. Die Befestigungselemente 4 und 5 sind metallisch, also elektrisch leitend und innerhalb der Stromschiene bzw des Stromschienengehäuses 2 mit dem Erdungsleiter verbunden. Da die Traversen ebenfalls metallisch sind, wird hierüber die erfindungsgemäße Zwangserdung der Traverse erzielt. Dieselbe wird dann nach der Montage an das Stromnetz und an ein Datensignalsystem angeschlossen.
Stirnseitig sind Steckkontakte 3 angeordnet. Da erfindungsgemäß nicht nur Kraftstrom verteilt werden soll, sondern auch Datensignale von Traverse zu Traverse und dort beliebig abgreifbar weitergeleitet werden sollen, sind auch Datenleitungen mit in die Stromschiene implementiert. Diese sind mit den stirnseitigen Datensignalsteckern 31 kontaktiert, während die Kraftstromleitungen mit den Kontaktstiften 30 verbunden sind. Dabei sind die Steckkontakte 3 als männliche (male) Steckkontaktanordnung ausgebildet. An der gegenüberliegenden Stirnseite einer solchen gerade Stromschiene ist dann der komplementäre Steckkontakt (female) 3' platziert. So können die Stromschienen direkt aneinander gesteckt werden.The busbar 2 is connected via the fastening elements 4 and 5 with the respective cross member 1. The fasteners 4 and 5 are metallic, so electrically conductive and connected within the busbar or the busbar housing 2 to the grounding conductor. Since the trusses are also metallic, the invention Zwangderdung the traverse is achieved over this. It is then connected to the power grid and data signal system after installation.
Front side plug contacts 3 are arranged. Since according to the invention not only power flow to be distributed, but also data signals from Traverse to Traverse and there are passed on any tapped, also data lines are implemented in the busbar. These are contacted with the front-side data signal plugs 31, while the power lines are connected to the contact pins 30. The plug contacts 3 are designed as a male (male) plug contact arrangement. On the opposite end side of such a straight busbar then the complementary plug contact (female) 3 'is placed. This allows the busbars to be connected directly to one another.

Wichtig ist hierbei dass bei dieser Ausführung die Kontaktierebene der Stromschiene in etwa gleich der mechanischen Verbindungsebene der Traverse 1 ist, in der Form dass der mechnische Verbindungshub und der elektrische Verbindungshub so gleich sind, dass bei Zusammenstecken der einzelnen Traversen zugleich dabei auch die elektrischen Steckkontakte zusammengefügt werden.It is important that in this embodiment, the contacting level of the busbar is approximately equal to the mechanical connection level of the crossmember 1, in the form that the mechnische Verbindungshub and the electrical Verbindungshub are so equal that when mating the individual trusses at the same time also joined the electrical plug contacts become.

Das Stromschienengehäuse enthält an seiner Oberseite 2b die Befestigungselemente 4 und 5 und an seiner Unterseite 2a die verteilt angeordneten Steckdosen 10 und Signalanschlüsse 11.The busbar housing includes on its upper side 2b, the fastening elements 4 and 5 and on its underside 2a, the distributed sockets 10 and signal terminals 11th

In Figur 2 wird die Oberseite 2b des Stromschienengehäuses 2 dargestellt. Dort sind entlang der Längserstreckung des Stromschienengehäuses sowohl Schutzkontaktsteckdosen 10 oder jede Form möglicher Niederspannungssteckverbinder als auch Datenanschlüsse bzw Datenanschlusskontakte 11 angeordnet. Hier nicht weiter dargestellt, sind die Vorsehung von Sicherungsautomaten, die die einzelnen Steckdosen in der oben beschriebenen Weise einzeln absichern, um die angeschlossene Leistung pro Steckdose so zu limitieren, das es zu keiner Belastung der Stromschiene über der Stromtragfähigkeitsgrenze der in dem Stromschienengehäuse angeordneten Leiterbahnen oder Leiterschienen kommen kann.In FIG. 2 the top 2b of the busbar housing 2 is shown. There are arranged along the longitudinal extent of the busbar housing both safety sockets 10 or any form of possible low-voltage connectors as well as data connections or data connection contacts 11. Not shown here, the providence of automatic circuit breakers that protect the individual sockets individually in the manner described above to limit the connected power per socket so that there is no burden on the busbar on the current carrying capacity of the arranged in the busbar housing tracks or Ladder rails can come.

Innerhalb des Stromschienengehäuses verlaufen auch Datensignaleitungen die über die Kontakte 31 von Schiene zu Schiene weitergeleitet werden.
Um Datensignale aufzufrischen sind in den Stromschienen integrierte Signalverstärker oder Signalauffrischer mit implementiert. Ist die Stromschiene in der Traverse montiert, so zeigen vorzugsweise die elektrischen Anschlüsse 10 und 11 nach oben, also in die Traverse hinein, gemäß Figur 1.Within the busbar housing also run data signal lines which are forwarded via the contacts 31 from rail to rail.
In order to refresh data signals, signal amplifiers or signal repeaters integrated in the busbars are also implemented. Is the busbar in the crossbar mounted, so preferably show the electrical connections 10 and 11 upwards, ie in the Traverse inside, according to FIG. 1 ,

In Figur 3 sind Beispiele für die Interkonnexion von Stromschienen gezeigt. Zur Montage wird in der Regel so vorgegangen, dass das jeweilige Stromschienengehäuse 2 über die Befestigungselemente 4, 5 an der jeweiligen Traverse 1 befestigt wird. Dann werden die Traversen zusammengesteckt und synchron werden über die Steckverbinder 20 und 21 auch die elektrischen Durchverbindungen bewerkstelligt. Dabei ist von besonderer Bedeutung dass ein solcher Durchverbinder ebenfalls sowohl Durchverbinder für Kraftstrom als auch für Datensignale in einer jeweils gemeinsamen Steckverbinderanordnung 20, 21 mit enthält.
Die Steckverbinder können zur Bewerkstelligung aller Montagefreiheitsgrade sowohl als gerader Durchverbinder, als auch als T-Verbinder ausgestaltet sein.In FIG. 3 Examples of the interconnection of busbars are shown. For assembly, the procedure is usually such that the respective busbar housing 2 is fastened via the fastening elements 4, 5 to the respective traverse 1. Then the trusses are put together and synchronously be accomplished via the connectors 20 and 21 and the electrical feedthroughs. It is of particular importance that such a connector also contains both through connectors for power and for data signals in a respective common connector assembly 20, 21 with.
The connectors can be configured to provide all mounting degrees of freedom both as a straight through connector and as a T-connector.

Eine dennoch effizientere und einfachere Interkonnexion der Stromschienen 2 ist in Figur 4 dargestellt.
Dort ist die Systematik von male und female Steckkontakten verwendet. D.h bei einer geraden Stromschiene 1 ist an einer Stirnseite eine male-Steckkontakt 3 und an der gegenüberliegenden Seite ein komplementärer female Steckkontakt. So kann eine Stromschiene an die anderer gesteckt werden.
Im unteren Bildteil von Figur 4 ist eine T-förmig verlaufende Stromschiene dargestellt. Dabei ist die Verteilung von female-Steckkontakten und male-Steckkontakten so verteilt, dass links ein male-Steckkontaktanschluss, rechts ein female-Steckkontaktanschluss, und am T-Stück ebenfalls ein female-Steckkontaktanschluss angeordnet ist.An even more efficient and simpler Interkonnexion of the busbars 2 is in FIG. 4 shown.
There, the system of male and female plug contacts is used. That is, in a straight busbar 1 is on one end face a male plug contact 3 and on the opposite side a complementary female plug contact. So a busbar can be plugged into the other.
In the lower part of the picture FIG. 4 a T-shaped busbar is shown. In this case, the distribution of female plug contacts and male plug contacts is distributed so that on the left a male plug contact, right a female plug contact, and the tee also a female plug contact connection is arranged.

So kann dann die weitere Verbindung mit anderen Stromschienen, bzw Traversen-Stromschienen-Anordnungen vorgenommen werden.So then the further connection with other busbars, or truss busbar arrangements can be made.
