Description

Die Erfindung betrifft eine elektrische Reihenklemme, insbesondere Mehrstockklemme, mit einem eine Rückwand aufweisenden, isolierenden Gehäuse und mindestens einer zwischen der Rückwand und einer dazu parallelen, vorderen Trennebene angeordneten Stromschiene, die aus Flachmaterial gebildet und mit ihrer größeren Querschnittsabmessung senkrecht zur Rückwand angeordnet ist, wobei die Stromschiene mindestens einen Steg aufweist, der zum Querschnittsausgleich von in die Stromschiene eingebrachten Aussparungen diese leitend überbrückt.The invention relates to an electrical terminal block, in particular a multi-level terminal block, with an insulating housing having a rear wall and at least one arranged between the rear wall and a parallel front parting plane Conductor rail made of flat material and with its larger cross-sectional dimension is arranged perpendicular to the rear wall, the busbar at least one Has web, which is used to compensate for the cross-section in the busbar Recesses bridged this conductive.

Derartige Reihenklemmen, wie sie aus der Praxis in zahlreichen Bauarten bekannt sind, wobei entweder eine einzelne Stromschiene oder aber mehrere, in mehreren "Etagen" übereinander angeordnete Stromschienen vorhanden sein können, sind aus der Praxis in zahlreichen Modifikationen bekannt. Überlicherweise werden derartige Reihenklemmen in großer Zahl neben- bzw. hintereinander auf einer Tragschiene angeordnet, wobei die einseitig offenen Gehäuse dicht an dicht angeordnet sind, so daß jeweils ein Gehäuse an seiner offenen Vorderseite entlang einer (gedachten) Trennebene durch die Rückwand eines benachbarten Gehäuses abgeschlossen wird.Such terminal blocks, as are known from practice in numerous designs, where either a single conductor rail or several, in several "levels" Busbars arranged one above the other can be found in practice in known numerous modifications. Such terminal blocks are usually used arranged in large numbers side by side or one behind the other on a mounting rail, the one-sided open housing are arranged close to each other so that one housing each its open front along a (imaginary) parting plane through the rear wall of a neighboring housing is completed.

Aufgrund der aus Platzgründen zunehmenden Verkleinerung derartiger Reihenklemmen kommt der Spannungsfestigkeit im Hinblick auf mögliche Durch- bzw. Überschläge wachsende Bedeutung zu, da die Stromschienen innerhalb der Gehäuse nicht eigenständig isoliert, sondern lediglich in einem gewissen Abstand voneinander angeordnet sind, so daß die Spannungsfestigkeit sich aufgrund der gebildeten Luftstrecken bzw. Kriechstrecken (entlang eines Pfades des isolierenden Gehäuses) ergibt. Eine Verkleinerung der Reihenklemmen geht daher mit einer zunehmenden Abnahme der Spannungsfestigkeit einher, wenn keine zusätzlichen, meist kostenträchtigen Maßnahmen zur Isolierung der Stromschienen getroffen werden.Due to the increasing size of such terminal blocks for reasons of space comes the dielectric strength with regard to possible breakdowns or arcing growing importance because the busbars within the housing are not independent isolated, but are only arranged at a certain distance from each other, so that the dielectric strength is due to the air gaps or creepage distances formed (along a path of the insulating case). A downsizing of Terminal blocks therefore go with an increasing decrease in dielectric strength if there are no additional, usually costly measures to isolate the Busbars are hit.

Die Erfindung hat sich zur Aufgabe gestellt, die Spannungsfestigkeit in Bezug auf die Gefahr von Überschlägen zwischen benachbarten Stromschienen bei einer gattungsgemäßen Reihenklemme zu verbessern.The invention has for its object the dielectric strength in relation to the Danger of flashovers between adjacent power rails in a generic Terminal block to improve.

Diese Aufgabe wird erfindungsgemäß bei einer gattungsgemäßen Reihenklemme dadurch gelöst, daß der Steg zumindest im Bereich seines freien, von der Stromschiene weg gerichteten Endabschnitts einen Abstand von der Trennebene aufweist.This object is achieved according to the invention in a generic terminal block solved that the web at least in the area of its free, directed away from the busbar End section has a distance from the parting plane.

Im Gegensatz zu der bislang üblichen Anordnung, bei der der Steg in bzw. unmittelbar benachbart zur Trennebene liegt, wodurch die Luft- bzw. Kriechstrecke zwischen benachbarten Stromschienen relativ kurz und die Überschlagsfestigkeit begrenzt ist, wird durch die erfindungsgemäße Anordnung, bei der sich der Steg in einem gewissen Abstand von der Trennebene befindet, die Entfernung zwischen benachbarten Stromschienen deutlich vergrößert und eine verlängerte Kriechstrecke bzw. eine zusätzliche Luftstrecke geschaffen, so daß die Überschlags- bzw. Spannungsfestigkeit einer Reihenklemme gegebener Größe zunimmt oder aber die Größe einer Reihenklemme unter Einhaltung einer bestimmten geforderten Spannungsfestigkeit reduziert werden kann. In contrast to the previously common arrangement in which the web is in or directly is adjacent to the parting plane, whereby the clearance or creepage distance between adjacent Busbars are relatively short and the dielectric strength is limited by the arrangement according to the invention, in which the web is at a certain distance from the parting line, the distance between adjacent power rails significantly enlarged and an extended creepage distance or an additional air gap created so that the flashover or dielectric strength of a terminal block given size increases or the size of a terminal block is observed a certain required dielectric strength can be reduced.

    • Zur grundsätzlichen Erläuterung der der Erfindung zugrunde liegenden Problematik sei zunächst auf Fig. 6 Bezug genommen, die eine mittige Querschnittsansicht einer bekannten Mehrstock-Reihenklemme zeigt. Das Kunststoffgehäuse 1 der Reihenklemme weist eine ebene Rückwand 2 auf und ist an seiner der Rückwand 2 gegenüberliegenden Vorderseite im Bereich einer vorderen Trennebene 3 zur Vorderseite hin (in Fig. 6 nach rechts) offen. Innerhalb des Gehäuses 1 sind in an sich bekannter Weise Stromschienen 5, 6 (und ggf. weitere Stromschienen) übereinander angeordnet. Die Anordnung ist hierbei bekanntermaßen so, daß die Stromschienen 5, 6 zum Querschnittsausgleich von Öffnungen bzw. Aussparungen, die in den Hauptteil 5a bzw. 6a der Stromschienen eingebracht sind, mit Stegen 5b, 6b versehen sind, wobei die Stege die Aussparungen, in Längsrichtung bzw. Verbindungsrichtung der Stromschienen gesehen, überbrücken, so daß im Bereich der Aussparungen (in Fig. 1 mit 110 bezeichnet) keine übermäßige bzw. unzulässige Erwärmung aufgrund erhöhter Stromdichten auftreten kann.For a basic explanation of the problem underlying the invention initially referring to FIG. 6, which is a central cross-sectional view of a known one Multi-level terminal block shows. The plastic housing 1 of the terminal block has a flat rear wall 2 and is opposite to the rear wall 2 Front in the area of a front parting plane 3 towards the front (in FIG. 6 after right) open. Within the housing 1 there are busbars 5, 6 (and possibly other busbars) arranged one above the other. The arrangement is here As is known, so that the busbars 5, 6 for cross-sectional compensation of openings or recesses, which are introduced into the main part 5a or 6a of the busbars are provided with webs 5b, 6b, the webs the recesses, in the longitudinal direction seen or connecting direction of the busbars, bridge, so that in the area the recesses (designated 110 in FIG. 1) are not excessive or impermissible Warming can occur due to increased current densities.

    Auf der dem Gehäuse 1 abgekehrten Seite der Trennebene 3 ist in Fig. 6 schematisch die Rückwand 2' einer unmittelbar benachbart angeordneten, weiteren Reihenklemme angedeutet, wobei das offene Gehäuse 1 durch die benachbarte Rückwand 2' entlang der Trennebene 3 verschlossen wird. Wie Fig. 6 weiter zeigt, ergibt sich durch die unmittelbar an den Stegen 5b, 6b anliegende Außenfläche der benachbarten Rückwand 2' eine bestimmte, in Bezug auf die Spannungs- bzw. Überschlagsfestigkeit der Stromschienen 5, 6 relevante Luftstrecke bzw. Kriechstrecke, die sich als Abstand des freien, von der Stromschiene 5a weg gerichteten Endabschnitts des Stegs 5b von der der Rückwand 2 weg gerichteten Seitenkante der Stromschiene 6a ergibt.On the side of the parting plane 3 facing away from the housing 1, this is schematically shown in FIG Rear wall 2 'of a directly adjacent, further terminal block indicated, the open housing 1 through the adjacent rear wall 2 'along the Partition level 3 is closed. As further shown in FIG. 6, this results directly from the on the webs 5b, 6b adjacent outer surface of the adjacent rear wall 2 ' certain, with respect to the voltage or breakdown strength of the conductor rails 5, 6 relevant air gap or creepage distance, which is the distance of the free, from the Busbar 5a facing end portion of the web 5b from that of the rear wall 2 away side edge of the busbar 6a results.

    Die Erfindung hat erkannt, daß es mit einer einfachen, aber höchst wirksamen Maßnahme ohne weiteres möglich ist, die in Fig. 6 bezeichnete Luftstrecke bzw. Kriechstrecke wesentlich zu verlängern und damit die Spannungsfestigkeit wesentlich zu verbessern.The invention has recognized that it is a simple but highly effective measure is easily possible, the air gap or creepage distance designated in FIG. 6 is essential to extend and thus significantly improve the dielectric strength.

    Zur Erläuterung der Erfindung sei zunächst auf Fig. 1 bis 3 Bezug genommen, wobei Teile, die der Darstellung in Fig. 6 entsprechen, mit entsprechenden, um 100 vergrößerten Bezugszeichen bezeichnet sind.To explain the invention, reference is first made to FIGS. 1 to 3, wherein Parts which correspond to the illustration in FIG. 6 with corresponding ones enlarged by 100 Reference numerals are designated.

    Fig. 1 zeigt die Stromschienenanordnung einer elektrischen Mehrstock-Reihenklemme schematisch, wobei die beiden unteren Stromschienen mit 105 und 106 bezeichnet sind. Die Darstellung nach Fig. 1 entspricht einer Blickrichtung ins Innere des nicht dargestellten Gehäuses, d.h. von vorn (in Fig. 6 von rechts oben), so daß die in Fig. 1 vorn liegenden freien Kanten der Stromschienen 105, 106 im Einbauzustand der Rückwand einer benachbarten Klemme zunächstliegen. Aussparungen 110 in den Hauptteilen 105a, 106a der Stromschienen 105, 106 sind durch Stege 105b, c und 106b überbrückt. Wie Fig. 2 zeigt, dienen die Aussparungen 110 beispielsweise zur Verbindung von Stromschienen untereinander mittels Brückern 111, 112 und/oder zur Verbindung entsprechender Stromschienen benachbarter Reihenklemmen (Brücker 113), und auch zur Aufnahme eines Anschlußelements 120, das dem Anschluß an eine Tragschiene 122 dient.Fig. 1 shows the busbar arrangement of an electrical multi-level terminal block schematically, the two lower busbars being designated 105 and 106. 1 corresponds to a direction of view into the interior of the not shown Housing, i.e. from the front (in Fig. 6 from the top right), so that those in front in Fig. 1 free edges of the busbars 105, 106 in the installed state of the rear wall adjacent terminal initially. Cutouts 110 in the main parts 105a, 106a the busbars 105, 106 are bridged by webs 105b, c and 106b. Like Fig. 2 shows, the recesses 110 are used, for example, to connect busbars with each other by means of bridges 111, 112 and / or for connecting corresponding busbars adjacent terminal blocks (jumper 113), and also to accommodate a connection element 120, which is used to connect to a mounting rail 122.

    Fig. 3 zeigt eine erfindungsgemäße Mehrstock-Reihenklemme in einer perspektivischen Ansicht von vorn, wobei neben dem Gehäuse 101 mit Rückwand 102 und den Stromschienen 105, 106 und 107 auch die an sich bekannten, senkrecht von der Rückwand 102 vorstehenden Verstärkungswände 130 erkennbar sind, die der Halterung und Fixierung der Stromschienen sowie der Versteifung des Gehäuses 1 dienen. Wie auch Fig. 3 zeigt, sind die Stege 105b, c und 106b so angeordnet, daß sie an der Rückwand 102 des Gehäuses 101 anliegen. Die Hauptteile 105a, 106a der Stromschiene 105, 106 sind hingegen in an sich bekannter Weise senkrecht zur Rückwand 102 angeordnet, parallel zu den Verstärkungswänden 130.Fig. 3 shows a multi-level terminal block according to the invention in a perspective View from the front, in addition to the housing 101 with the rear wall 102 and the busbars 105, 106 and 107 also those known per se, perpendicular to the rear wall 102 protruding reinforcement walls 130 can be seen, the bracket and fixation the busbars and the stiffening of the housing 1 serve. 3 also shows the webs 105b, c and 106b are arranged so that they on the rear wall 102 of the housing 101 concerns. The main parts 105a, 106a of the busbar 105, 106, however, are in arranged in a known manner perpendicular to the rear wall 102, parallel to the reinforcement walls 130th

    Fig. 4 und 5 erläutern die Vorteile der erfindungsgemäßen Anordnung. Dadurch, daß die Stromschienen 105 und 106 durch (mindestens) eine Verstärkungswand 130 voneinander getrennt sind, ergibt sich durch die Verlagerung des Stegs 105b an die Rückwand 102 eine wesentliche Verlängerung der Kriechstrecke (Fig. 4) bzw. eine Schaffung einer bislang nicht vorhandenen Luftstrecke (Fig. 5), so daß die Überschlagsfestigkeit zwischen den Stromschienen 105 und 106 erheblich verbessert wird. Entsprechendes gilt für den Steg 106b.4 and 5 explain the advantages of the arrangement according to the invention. Because the Busbars 105 and 106 through (at least) one reinforcement wall 130 from each other are separated, one results from the displacement of the web 105b on the rear wall 102 substantial extension of the creepage distance (Fig. 4) or creating a hitherto not existing air gap (Fig. 5), so that the flashover resistance between the busbars 105 and 106 is significantly improved. The same applies to the Bridge 106b.

    Die Stege 105b, c bzw. 106b sind in der dargestellten Ausführungsform durch Abkanten eines einheitlichen Stücks Flachmaterial einstückig mit der jeweiligen Stromschiene hergestellt, könnten allerdings alternativ auch auf andere Weise auf dem Hauptteil 105a bzw. 106a einer Stromschiene angebracht sein. Unabhängig von der Art und Weise der Herstellung werden die erfindungsgemäßen Vorteile auch dann erreicht, wenn der Steg nicht in der dargestellten Weise an der Rückwand der Klemme anliegt, sondern abgewinkelt in Bezug auf den Hauptteil der Stromschiene verläuft, sofern dafür gesorgt ist, daß der Steg einen (zusätzlichen) Abstand von der Trennebene 103 bzw. einer im zusammengesetzten Zustand benachbarten Rückwand einer benachbarten Reihenklemme aufweist, so daß eine längere Kriechstrecke bzw. eine zusätzliche Luftstrecke geschaffen wird. The webs 105b, c and 106b are in the illustrated embodiment by folding a uniform piece of flat material made in one piece with the respective busbar, alternatively, however, could alternatively be on the main part 105a or 106a of a busbar. Regardless of the way of manufacture The advantages according to the invention are also achieved when the web is not abuts in the manner shown on the rear wall of the terminal, but angled in Relation to the main part of the busbar runs, if it is ensured that the web an (additional) distance from the parting plane 103 or one in the composite State adjacent rear wall of an adjacent terminal block, so that a longer creepage distance or an additional air gap is created.

    Beispielsweise könnte sich der Steg auf der der Rückwand abgewandten Seitenkante der Stromschiene befinden (in Fig. 4 und 5 auf der rechten statt auf der linken Seite), sofern er von der Trennebene 103 weg in Richtung auf die Rückwand der Klemme abgewinkelt ist. Alternativ könnte der Steg auch parallel zur Rückwand und in einem mittleren Bereich der Breite der Stromschiene angeordnet sein. For example, the web could be on the side edge of the side facing away from the rear wall Conductor rails are provided (in Fig. 4 and 5 on the right instead of on the left), provided he angled away from the parting plane 103 towards the rear wall of the terminal is. Alternatively, the web could also be parallel to the rear wall and in a central area the width of the busbar.
