Description

Die vorliegende Erfindung betrifft eine elektrische Verteileranordnung zur Verteilung elektrischer Leistung. Es ist beispielsweise bei einem Verbinder für elektrische Bus-Leiter (DE 94 10 614 U1) bekannt, aus einer mehrpoligen Verbinderleiste mit pro Pol jeweils einem oder mehreren Anschlußelementen für ankommende und abgehende Leiterenden, die elektrisch durch ein Verbindungsstück miteinander verbunden sind, den elektrischen Verbindungsstücken jeweils ein elektrisches Steckverbinderelement für ein anlagenseitig entsprechendes Steckverbinderelement zuzuordnen, so daß nach Lösen der Steckverbindung zwar die Anlage von der Leistungszufuhr abgeschaltet ist, die elektrische Verbindung zwischen dem ankommenden und abgehenden Ende des Bus-Leiters jedoch aufrechterhalten bleibt. Der Verbinder wirkt hier somit in Art eines Anschlußsteckers.The present invention relates to an electrical distributor arrangement for distributing electrical power. It is known, for example, in a connector for electrical bus conductors (DE 94 10 614 U1), the electrical connectors from a multipole connector strip with one or more connection elements for each pole for incoming and outgoing conductor ends that are electrically connected to one another by a connector to assign an electrical connector element for a corresponding connector element on the system side, so that after loosening the plug connection the system is switched off from the power supply, but the electrical connection between the incoming and outgoing end of the bus conductor is maintained. The connector thus acts in the manner of a connector.

Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, eine elektrische Verteileranordnung zu schaffen, die mit einem minimalen Verdraht-ungsaufwand und sehr geringem Platzbedarf eine einfache Möglichkeit einer vielfachen Verzweigung einer zugeführten elektrischen Leistung invariabler Ausgestaltung gewährleistet.The present invention is based on the object of creating an electrical distributor arrangement which, with a minimal wiring expenditure and very small space requirement, ensures a simple possibility of multiple branching of a supplied electrical power of an invariable configuration.

Die erfindungsgemäße Lösung besteht im wesentlichen in einer elektri-schen Verteileranordnung mit einem mehrpoligen Anschlußstecker für die Leistungszufuhr und mehreren mehrpoligen Anschlußsteckern für den Leistungsabgriff, jeweils mit Leiteranschlüssen und damit über Stromschienenstücke verbundenen Steckverbindern entsprechend der Polzahl und ferner mit einem mehrpoligen, scheibenförmig aufgebauten Verteilerblock, in dessen Scheiben jeweils Steckverbinder für die jeweiligen Steckverbinder der Anschlußstecker vorgesehen sind, die durch Stromschienenstücke elektrisch miteinander verbunden sind, wobei in den mehrpoligen Anschlußblöcken und deren Stromschienenstücken Steckaufnahmen für elektrische Querverbinder vorgesehen sind und der Anschlußstecker für die Leistungszufuhr nur an einem Pol mit einem ankommenden Leiter verdrahtet ist und von diesem Leiteranschluß aus die Leistung über einen gesteckten Querverbinder auf die anderen Pole des Anschlußsteckers verteilt ist.The solution according to the invention essentially consists in an electrical distributor arrangement with a multi-pole connector for the power supply and a plurality of multi-pin connectors for power tapping, each with conductor connections and thus connectors connected via busbar pieces in accordance with the number of poles and also with a multi-pin, disk-shaped distribution block, in the disks of which connectors for the respective connectors of the connector plugs are provided, which are electrically connected to one another by busbar pieces are, in the multi-pole terminal blocks and their busbar plug receptacles for electrical cross connectors are provided and the connector for the power supply is wired to only one pole with an incoming conductor and from this conductor connection the power is distributed to the other poles of the connector via a plug cross connector is.

Dank dieser Ausgestaltung kann beim Anschlußstecker für die Leistungs-zufuhr außerordentlich an Verdrahtung und damit Platz- und Montageaufwand gespart werden, da nur eine Verdrahtung durchzuführen ist und von diesem Pol aus die Leistungsverteilung in diesem Anschlußstecker durch den Querverbinder erfolgt. Ausgehend von dieser einen Stelle der Leistungszufuhr kann mit geringem Aufwand eine außerordentlich umfassende Leistungsverzweigung erfolgen, und zwar über den Verteiler-block zu mehreren Anschlußsteckern für den Leistungsabgriff, die also zu Verbrauchern führen, wenn beispielsweise drei derartige Anschlußstecker für den Leistungsabgriff vorgesehen sind und wenn beispielsweise, wie gemäß einer zweckmäßigen Ausgestaltung vorgesehen, jeder dieser Anschlußstecker pro Pol zwei Leiteranschlüsse für abgehende Leiter hat, kann die Leistung mehrpolig sechsfach verzweigt werden. Dadurch, daß alle Anschlußstecker, also auch die für den Leistungsabgriff, Steckaufnahmen für Querverbinder haben, ist die Leistungsverzweigung auch außerordentlich variabel und ausbaufähig. Kommen beispielsweise für einen betroffenen Anschlußstecker im Bedarfsfall noch mehrere Verbraucher hinzu, kann man einfache Anschlußscheiben ohne Steckverbindung zum Verteilerblock anfügen und diesem über einen gesteckten Querverbinder Leistung zuführen. Über den Querverbinder kannauch eine weitere Leistungsquerverteilung auf Verbinderleisten oder dergleichen erfolgen, die ohne eigene Steckverbindungsmöglichkeit zum Verteilerblock sind, an die dann aber weitere Verbraucher angeschlossen werden können.Thanks to this configuration, a great deal of wiring and thus space and assembly effort can be saved in the connector for the power supply, since only wiring is required and the power distribution in this connector is carried out by the cross connector from this pole. Starting from this one point of the power supply, an extraordinarily extensive power branching can be carried out with little effort, namely via the distributor block to a plurality of connector plugs for the power tap, which thus lead to consumers if, for example, three such connector plugs are provided for the power tap and if, for example As provided in accordance with an expedient embodiment, each of these connectors has two conductor connections for outgoing conductors per pole, the power can be branched into six poles. Because all connectors, including those for power tapping, have plug receptacles for cross connectors, the power split is also extremely variable and expandable. If, for example, several consumers are added for an affected connector, simple connection disks can be attached to the distributor block without a plug connection and power can be supplied to it via an inserted cross connector. A further power cross-distribution can also take place on connector strips or the like via the cross connector, which are without their own plug connection option to the distribution block, but to which further consumers can then be connected.

Hervorzuheben ist ferner die problemlose Abtrennung angeschlossener Verbraucher von der Hauptleitung, ohne daß diese unterbrochen werden muß. Die betroffenen Anschlußstecker für den Leistungsabgriff werden einfach gezogen, wie das zu Prüfzwecken oder Wartungs- und Reparaturarbeiten benötigt wird, ohne daß andere Verbraucher abgeschaltet werden müssen.Also to be emphasized is the problem-free separation of connected consumers from the main line, without this having to be interrupted. The affected connector for the power tap are simply pulled, like that too Testing purposes or maintenance and repair work is required without having to switch off other consumers.

Die Montage einer elektrischen Schaltanlage mit einer derartigen elektrischen Verteileranordnung ist außerordentlich vereinfacht, da anwenderseitig keine Verdrahtungsarbeiten durchzuführen sind. Es kann in denkbar einfacher Weise mit Anschlußsteckern mit von der Herstellerseite vorkonfektionierten Leitungen gearbeitet werden. Die Endmontage durch Steckverbindung ist einfach und schnell ohne Spezialkenntnisse durchzuführen.The assembly of an electrical switchgear with such an electrical distributor arrangement is extremely simplified, since no wiring work has to be carried out by the user. It can be worked in a very simple manner with connectors with cables pre-assembled by the manufacturer. The final assembly by plug-in connection can be carried out quickly and easily without special knowledge.

Spezielle Funktionsprüfungen sind unabhängig voneinander problemlos durchzuführen, wozu im Bedarfsfall auch Querverbinder gezogen werden können.Special function tests can be carried out independently of one another without any problems, for which purpose cross connectors can also be pulled if necessary.

Weitere bevorzugte Ausgestaltungen sind in Unteransprüchen gekennzeichnet. Hervorzuheben ist eine Ausgestaltung, nach der der Querverbinder für einen oder mehrere Anschlußstecker als Trennstecker ausgebildet ist, so daß mit diesem Trennstecker einzelne Strompfade in den Polen der Anschlußstecker trennbar sind, während andere Funktionen der anderen Strompfade erhalten bleiben können. Dies führt in besonders großem Ausmaß zu gezielten Abschaltungen zu Prüf- und Wartungszwecken unter besonders weitgehender Aufrechterhaltung davon nicht betroffener Funktionen im übrigen.Further preferred configurations are characterized in the subclaims. Of particular note is an embodiment according to which the cross connector for one or more connecting plugs is designed as a separating plug, so that individual current paths in the poles of the connecting plugs can be separated with this separating plug, while other functions of the other current paths can be retained. This leads to a particularly large extent to targeted shutdowns for testing and maintenance purposes while maintaining functions that are not affected by it to a particularly large extent.

In zweckmäßiger Ausgestaltung ist auch in dem aus Scheiben aufgebauten Verteilerblock eine Steckaufnahme für einen Querverbinder vorgesehen, mit dem die Stromschienenstücke einzelner Scheiben, insbesondere auch eines benachbarten Verteilerblockes, elektrisch verbindbar sind, so daß auch insoweit im Bereich des Verteilerblockes noch eine weitere Leistungsverteilungsmöglichkeit zusätzlich geschaffen ist.In an expedient embodiment, a plug-in receptacle for a cross connector is also provided in the distributor block constructed from disks, with which the busbar pieces of individual disks, in particular also an adjacent distributor block, can be electrically connected, so that a further power distribution option is additionally created in the area of the distributor block .

Ausführungsbeispiele einer elektrischen Verteileranordnung gemäß der Erfindung werden nachfolgend in Bezug auf die Zeichnung näher beschrieben.Exemplary embodiments of an electrical distributor arrangement according to the invention are described in more detail below with reference to the drawing.

Bei der in Figur 1 dargestellten elektrischen Verteileranordnung ist als zentrales Verteilelement ein Verteilerblock 1 vorgesehen, der aus einer Mehrzahl einzelner Scheiben, von denen in Figur 1 eine in Seiten-ansicht zu sehen ist, mehrpolig aufgebaut ist. Die Anreihung der Scheiben erstreckt sich gesehen auf die Zeichnung beispielsweise in deren Tiefe. In dem Gehäuse 2 einer jeden Scheibe des Verteilerblockes 1 befinden sich im dargestellten Ausführungsbeispiel insgesamt vier Steckverbinder 3, 4, beispielsweise buchsenförmige Steckverbinder 3 und stiftförmige Steckverbinder 4. Die vier Steckverbinder 3, 4 sind untereinander elektrisch leitend in jeder Scheibe durch ein im wesentlichen U-förmiges, verzweigtes Stromschienenstück 5 elektrisch leitend miteinander verbunden. Insbesondere die stiftförmigen Steckverbinder 4 können mit Hilfe gesonderter Kunststoffeinsätze 6 im Scheibengehäuse 2 festgelegt werden. Durch entsprechende Ausgestaltung der Gehäuse 2 der Scheiben kann der Verteilerblock 1 in seiner Gesamtheit eine Rastfußanordnung 7 haben, so daß er insgesamt beispielsweise auf einer Tragschiene verrastet werden kann.In the case of the electrical distributor arrangement shown in FIG. 1, a distributor block 1 is provided as the central distributor element, which is composed of a plurality of individual disks, one of which can be seen in a side view in FIG. 1. The baying of the panes extends to the drawing, for example, in their depth. In the illustrated embodiment, there are a total of four connectors 3, 4, for example socket-shaped connectors 3 and pin-shaped connectors 4, in the housing 2 of each disk of the distributor block 1. The four connectors 3, 4 are mutually electrically conductive in each disk by an essentially U- shaped, branched busbar piece 5 electrically connected together. In particular, the pin-shaped plug connector 4 can be fixed in the disk housing 2 with the aid of separate plastic inserts 6. By appropriately designing the housing 2 of the disks, the distributor block 1 can have a latching foot arrangement 7 in its entirety, so that it can be latched overall, for example, on a mounting rail.

In dem dargestellten Ausführungsbeispiel sind zur elektrischen und mechanischen Steckverbindung mit dem Verteilerblock 1 insgesamt vier Anschlußstecker 8, 9, 10 vorgesehen, die ebenfalls mehrpolig ausgebildet sind. Im dargestellten Ausführungsbeispiel dient der Anschlußstecker 8 der Leistungszufuhr. Er hat, wie auch die anderen Anschlußstecker 9, 10, pro Pol zwei Leiteranschlüsse 11, die durch eine Stromschiene 12 mit dem in diesem Fall buchsenförmigen Steckverbinder 3 des betroffenen Poles elektrisch leitend verbunden sind. Die Stromschiene 12 hat eine nach oben weisende Abwinklung 13, von derem oberen Ende nach hinten eine weitere Abwinklung 14 ausgeht, in der sich die Stecköffnung für einen Querverbidner 15 befindet, für dessen obere durchgehende Querleiste sich in der Anreihung der Pole des Gehäuses des Anschlußsteckers 8 eine Stecköffnung befindet, wobei in den einzelnen Polen im Gehäuse entsprechende Stecköffnungen für die einzelnen kammartigen Zinken 16 des Querverbinders 15 vorgesehen sind.In the illustrated embodiment, a total of four connectors 8, 9, 10 are provided for electrical and mechanical plug connection with the distributor block 1, which are also multi-pole. In the illustrated embodiment, the connector 8 is used to supply power. Like the other connectors 9, 10, it has two conductor connections 11 per pole, which are connected in an electrically conductive manner by a busbar 12 to the connector 3 in this case, which is socket-shaped. The busbar 12 has an upward-pointing bend 13, from the upper end of which a further bend 14 extends, in which there is the plug-in opening for a cross connector 15, for the upper continuous cross-bar of which the rows of poles of the housing of the connector plug 8 are arranged there is a plug-in opening, corresponding plug-in openings for the individual comb-like tines 16 of the cross connector 15 being provided in the individual poles in the housing.

Erfindungswesentlich ist, daß dieser Anschlußstecker 8 für die Leistungszufuhr nur an einem Pol mit seinem Leiteranschluß 11 mit einem ankommenden elektrischen Leiter 17 verdrahtet ist. Im dargestellten Ausführungsbeispiel sind alle Leiteranschlüsse 11 als Klemmfederanschlüsse dargestellt.It is essential to the invention that this connector 8 for the power supply is only wired to one pole with its conductor connection 11 to an incoming electrical conductor 17. In the illustrated embodiment, all conductor connections 11 are shown as clamping spring connections.

Ausgehend von diesem einen Leiteranschluß 11 mit angeschlossenem, ankommenden Leiter 17 wird die Leistung in dem Anschlußstecker 8 über den gesteckten Querverbinder 15 auf die Stromschienen 12 der übrigen Pole verteilt. Alle Stromschienen 12 sind mit einem in diesem Fall buchsenförmigen Steckverbinder 18 fest verbunden. Durch die geschilderten Abwinklungen 13, 14 der Stromschiene 12 mit der Stecköffnung für den Querverbinder 15, 16 kann diese Leistungsübertragungszone zwischen der Stromschiene 12 und dem Steckverbinder 18 insoweit ohne Durchbrechung oder dergleichen damit auf dem vollen Leistungsübertragungsquerschnitt gehalten werden. Durch die geschilderte Anordnung erfolgt die Leistungsverteilung im Anschlußstecker 8 somit auch auf alle seine Steckverbinder 18.Starting from this one conductor connection 11 with connected incoming conductor 17, the power in the connector 8 is distributed over the plugged cross connector 15 to the conductor rails 12 of the other poles. All busbars 12 are firmly connected to a connector 18, which in this case is socket-shaped. Due to the described bends 13, 14 of the busbar 12 with the plug-in opening for the cross connector 15, 16, this power transmission zone between the busbar 12 and the connector 18 can thus be kept on the full power transmission cross-section to this extent without opening or the like. Due to the arrangement described, the power distribution in the connector 8 is thus also carried out on all of its connectors 18.

Nach Einstecken des Anschlußsteckers 8 in die in diesem Fall dann stiftförmigen Steckverbinder 4, die für den Anschluß des Anschlußsteckers 8 im Verteilerblock vorgesehen sind, erfolgt im Verteilerblock 1 die Leistungsverteilung auf dessen Stromschienenstücke 5 in den einzelnen Polen und dort zu den übrigen Steckverbindern 3, 4 im Verteilerblock 1 und steht dort zum Abgriff durch die weiteren Anschlußstecker 9, 10, die dem Leistungsabgriff und der Leistungsverteilung zu den Verbrauchern dienen, zur Verfügung.After inserting the connector 8 into the then pin-shaped connector 4, which are provided for connecting the connector 8 in the distribution block, the power distribution takes place in the distributor block 1 on its conductor rail pieces 5 in the individual poles and there to the other connectors 3, 4 in the distributor block 1 and is available there for tapping through the further connecting plugs 9, 10, which are used for power tapping and power distribution to the consumers.

Im dargestellten Ausführungsbeispiel ist ein Anschlußstecker 9 für den Leistungsabgriff vorgesehen, der baugleich mit dem zuvor geschilderten Anschlußstecker 8 ist, so daß auf dessen vorstehende Beschreibung verwiesen werden kann. Die pro Pol zwei Leiteranschlüsse 11 im Anschlußstecker 9 können mit zu entsprechenden Verbrauchern führenden abgehenden Leitern 19 verdrahtet werden. Bei diesem Anschlußstecker 9 für den Leistungsabgriff kann der Querverbinder 15 gesteckt werden, um eine weitere Querverteilung der Leistung ausgehend von dem Anschlußstecker 9 zu benachbarten Steckern, Anschlußleisten oder dergleichen durchzuführen, die dann keine eigene Steckverbindung zum Verteilerblock 1 haben müssen. Auf diese Weise können auch später bei Ergänzung oder Erweiterung der Anlage einfach an den Anschlußstecker 9 anzufügende Anschlußscheiben ohne eigene Steckverbindung zum Verteilerblock problemlos an Leistung gelegt werden.In the illustrated embodiment, a connector 9 is provided for the power tap, which is structurally identical to the connector 8 described above, so that reference can be made to the above description. The two conductor connections 11 in the connector 9 per pole can be wired to outgoing conductors 19 leading to corresponding consumers. With this connector 9 for the power tap, the cross connector 15 can be inserted in order to carry out a further transverse distribution of the power starting from the connector 9 to neighboring connectors, terminal strips or the like, which then do not have to have their own plug connection to the distributor block 1. In this way, even when the system is expanded or expanded, connecting disks to be attached to the connector plug 9 can be easily connected to power without a separate plug connection to the distributor block.

Im dargestellten Ausführungsbeispiel sind zwei weitere Anschlußstecker 10 für den Leistungsabgriff vorgesehen, die ebenfalls mehrpolig sind und im Grundaufbau den Anschlußsteckern 8, 9 ähneln. Sie können wahlweise wieder mit buchsenförmigen Steckverbindern 18 oder mit stift-förmigen Stiftverbindern 20 pro Pol versehen sein. Sie unterscheiden sich von den vorstehend beschriebenen Anschlußsteckern 8, 9 im wesent-lichen durch eine etwas andere Ausgestaltung der Stromschienenstücke zwischen den beiden Leiteranschlüssen 11 pro Pol im Hinblick darauf, daß sie zur Verwendung mit Querverbindern 21 in Form von Trennsteckern ausgebildet sind. Verschiedene diesbezügliche Ausgestaltungen sind insbesondere in den Figuren 2 - 4 im einzelnen dargestellt.In the illustrated embodiment, two further connectors 10 are provided for the power tap, which are also multi-pole and resemble the connectors 8, 9 in the basic structure. You can either be provided with socket-shaped connectors 18 or with pin-shaped pin connectors 20 per pole. They differ from the connectors 8, 9 described above in essential by a somewhat different design of the busbar pieces between the two conductor connections 11 per pole in view of the fact that they are designed for use with cross connectors 21 in the form of isolating plugs. Various configurations in this regard are shown in detail in particular in FIGS. 2-4.

Im Ausführungsbeispiel nach Figur 2 ist ein Pol eines mehrpoligen Anschlußsteckers 10 gezeigt, bei dem lediglich der rechts auf die Zeichnung gesehene Leiteranschluß 11 mittels einer gesonderten Verbindungslasche 22 einer im übrigen zweigeteilten Stromschiene 23 direkt und fest mit dem dort stiftförmigen Steckverbinder 20 elektrisch leitend verbunden ist. Die Elemente der geteilten Stromschiene 23 haben im übrigen jeweils an ihren von den Leiteranschlüssen 11 abgewandten Enden nach oben gerichtete Abwinklungen 24, wobei die Abwinklungen 24 der beiden Stromschienenteile 23 abständig zueinander liegen und damit eine Stecköffnung 25 bilden, in die in diesem Pol einer der kammartigen Zinken 26 des Trennsteckers 21 gesteckt werden kann. Die kammartigen Zinken 26 haben einen relativ kurzen, elektrisch leitenden Abschnitt 27, der nach Kontaktierung durch Einsteckung in die Stecköffnung 25 die beiden Stromschienenteile 23 leitend miteinander verbindet. Wird bei dieser Ausgestaltung der Trennstecker 21 gezogen, verbleiben die Leiteranschlüsse 11 gesehen auf die Zeichnung der rechten Seite des mehrpoligen Anschlußsteckers 10 in leitender Verbindung mit der Leistungszufuhr, wäre diese lediglich zu den gesehen auf der Zeichnung linken Seite liegenden Leiteranschlüssen 11 unterbrochen ist, also nur diese ent-sprechenden Strompfade abgeschaltet sind. Dies ist in Figur 2 symbolisch mit aufskizziert.In the exemplary embodiment according to FIG. 2, a pole of a multipole connector 10 is shown, in which only the conductor connection 11 seen on the right of the drawing is directly and firmly connected in an electrically conductive manner to the connector 20, which is in the form of a pin, by means of a separate connecting strap 22. The elements of the divided busbar 23 have, moreover, at their ends facing away from the conductor connections 11 upward bends 24, the bends 24 of the two busbar parts 23 being spaced apart and thus forming a plug opening 25 into which one of the comb-like in this pole Prongs 26 of the isolating plug 21 can be inserted. The comb-like tines 26 have a relatively short, electrically conductive section 27, which, after being contacted by being inserted into the plug-in opening 25, conductively connects the two busbar parts 23 to one another. If the isolating plug 21 is pulled in this embodiment, the conductor connections 11, seen on the drawing of the right side of the multipole connector 10, remain in conductive connection with the power supply, if this were only interrupted to the conductor connections 11 lying on the drawing on the left side, that is to say only these corresponding current paths are switched off. This is symbolically outlined in FIG. 2.

Figur 3 illustriert bei grundsätzlich gleichem Grundaufbau eine ähnliche Funktionsweise. Hier ist jetzt lediglich der links liegende Stromschienenteil 23 dauerhaft mit der Verbindungslasche 22 mit dem stiftförmigen Steckverbinder 20 verbunden, so daß nach Ziehen des Trennsteckers 21 nunmehr die links liegenden Leiteranschlüsse 11 der Leistungszufuhr verbleiben, während die rechts liegenden Leiteranschlüsse 11 und damit die entsprechenden Strompfade getrennt sind, wie im Zusammenhang mit Figur 3 ebenfalls aufskizziert.Figure 3 illustrates a similar operation with the same basic structure. Here now only the left busbar part 23 is permanently connected to the connecting tab 22 with the pin-shaped connector 20, so that after pulling the isolating plug 21, the left-hand conductor connections 11 of the power supply now remain, while the right-hand conductor connections 11 and thus the corresponding current paths are separated are, as outlined in connection with Figure 3 also.

Eine weitere mögliche Ausgestaltung ist in Figur 4 illustriert. Bei dieser Ausführungsform haben die Zinken 26' des Trennsteckers 21' einen relativ langen leitenden Abschnitt 27'. Die beiden Stromschienenteile 23', die zu den Leiteranschlüssen 11 führen, haben keine eigene direkte und unmittelbare Verbindung zu dem Steckverbinder 20, es fehlt somit eine entsprechende Verbindungslasche 22. Dafür ist fest mit dem Steckverbinder 20 ein buchsenförmiges Verbindungsstück 22' verbunden, in das der untere Endbereich der Zinken 26' des Trennsteckers 21', auch mit einem noch leitenden Abschnittsbereich eingesteckt werden kann. Diese Ausgestaltung ermöglicht zwei verschiedene Schaltungszustände, wie in Figur 4 aufskizziert. Wird der Trennstecker 21' vollständig gezogen oder zumindest so weit gezogen, daß sein leitender Abschnitt 27' auch die oberen abgewinkelten Enden der Stromschienenteile 23' nicht mehr kontaktiert, sind sämtliche Leiteranschlüsse 11 von der Leistungszufuhr abgetrennt, wie in der rechten Skizze illustriert.Another possible embodiment is illustrated in FIG. 4. In this embodiment, the prongs 26 'of the isolating plug 21' have a relatively long conductive section 27 '. The two busbar parts 23 ', which lead to the conductor connections 11, do not have their own direct and direct connection to the plug connector 20, and a corresponding connecting tab 22 is therefore missing. For this purpose, the plug connector 20 is fixed in the form of a socket Connecting piece 22 'connected, into which the lower end region of the prongs 26' of the isolating plug 21 'can also be inserted with a still conductive section region. This configuration enables two different circuit states, as outlined in FIG. 4. If the isolating plug 21 'is pulled completely or at least pulled so far that its conductive section 27' also no longer contacts the upper angled ends of the busbar parts 23 ', all conductor connections 11 are disconnected from the power supply, as illustrated in the sketch on the right.

Wird der Trennstecker 21' nur so weit gezogen, daß sein leitender Abschnitt 27' nicht mehr das buchsenförmige Verbindungsstück 22' kontaktiert, aber noch die entsprechenden Enden der Stromschienenstücke 23', ist damit die Verbindung zur Leistungszufuhr durch den Verteilerblock 1 unterbrochen, doch bleiben die beiden Leiteranschlüsse 11 in jedem der Pole des Anschlußsteckers 10 weiterhin leitend miteinander verbunden, wie in der linken Skizze in Figur 4 illustriert.If the isolating plug 21 'is only pulled so far that its conductive section 27' no longer contacts the socket-shaped connecting piece 22 ', but still the corresponding ends of the busbar pieces 23', the connection to the power supply through the distributor block 1 is thus interrupted, but they remain two conductor connections 11 in each of the poles of the connector 10 continue to be conductively connected to one another, as illustrated in the left sketch in FIG.

Wie in Figur 1 illustriert, kann es zweckmäßig sein, auch in den Gehäusen 2 der Scheiben des Verteilerblockes 1 und damit insgesamt in diesem sowie in seinen Stromschienenstücken 5 in den einzelnen Scheiben eine Steckaufnahme für einen Querverbinder 15 vorzusehen. Dieses ermöglicht im Bedarfsfall eine weitere zusätzliche Querverteilung der elektrischen Leistung ausgehend von einem solchen Verteilerblock 1 zu anderen angrenzenden Verteilerblöcken oder sonstigen elektrischen Anschlußelementen, die an einen solchen Verteilerblock auf einer Tragschiene angereiht sein können.As illustrated in FIG. 1, it may be expedient to also provide a plug-in receptacle for a cross connector 15 in the housings 2 of the disks of the distributor block 1 and thus overall in this as well as in its conductor rail pieces 5 in the individual disks. If necessary, this enables a further additional transverse distribution of the electrical power starting from such a distributor block 1 to other adjacent distributor blocks or other electrical connection elements which can be lined up on such a distributor block on a mounting rail.
