Description

Die Erfindung betrifft einen Klemmenblock zum Anschluß von Einzelleitern an Flachbandleitungen, mit einem die Einzel­leiteranschlüsse beinhaltenden Klemmenblock, einem Flach­bandleitungsanschluß und einem den Klemmenblock und den Flachbandleitungsanschluß aufnehmenden, festsetzbaren Unter­teil.The invention relates to a terminal block for connecting individual conductors to ribbon cables, with a terminal block containing the individual conductor connections, a ribbon cable connection and a fixable lower part receiving the terminal block and the ribbon cable connection.

Anschlußklemmenblocks der gattungsgemäßen Art, die auch als Übergabeelemente für Flachbandleitungen zu bezeichnen sind, haben bislang einen mechanisch und insbesondere elektrisch komplizierten Aufbau mit vielen Kontaktstellen. Bei den be­kannten Anordnungen wird nämlich das anzuschließende Ende der Flachbandleitung mit dem einen Element eines mehrpoligen Steckverbinders versehen, dessen Gegenstück, also beispiels­weise das entsprechende Buchsenelement eines derartigen mehr­poligen Steckverbinders, mit einer zweckentsprechend be­druckten Leiterplatte versehen wird. Die Leiterplatte ihrer­seits wird dann in einem Unterteil aus Isolierstoff montiert, wobei das Unterteil beispielsweise Rastfüße zum Aufrasten auf Normtragschienen aufweist, oder mit Anschlußwinkeln zum Fest­legen auf ebenen Flächen versehen ist. Auf der Leiterplatte selbst wird dann ferner der Anschlußklemmenblock montiert, der die Einzelleiteranschlüsse beinhaltet.Terminal blocks of the generic type, which can also be referred to as transfer elements for ribbon cables, have hitherto been of a mechanically and in particular electrically complicated structure with many contact points. In the known arrangements, namely the end of the ribbon cable to be connected is provided with one element of a multipole connector, the counterpart of which, for example the corresponding socket element of such a multipole connector, is provided with an appropriately printed circuit board. The circuit board in turn is then mounted in a lower part made of insulating material, the lower part having, for example, snap-in feet for snapping onto standard mounting rails, or being provided with connecting angles for fixing on flat surfaces. The terminal block, which contains the individual conductor connections, is then also mounted on the circuit board itself.

Die vorstehend geschilderte Anordnung hat Kontaktstellen zwischen den Flachbandleitungen und dem Steckverbinder, im Steckverbinder selbst, im Anschluß des einen Elementes des Steckverbinders an der Leiterplatte, im Übergang zur Leiter­bahn und im Abgang von diesem zu den Anschlußstiften im Klemmenblock, in der Verbindung zwischen den Anschlußstiften zum Zugbügel bei Ausführung der Einzelleiteranschlüsse bei­spielsweise als Schraubanschlüsse sowie im Anschlußbereich des anzuschließenden Einzelleiters im Zugbügel.The arrangement described above has contact points between the ribbon cables and the connector, in the connector itself, in the connection of one element of the connector to the circuit board, in the transition to the conductor track and in the outlet from this to the connecting pins in the terminal block, in the connection between the connecting pins Drawbar when designing the individual conductor connections, for example as screw connections and in the connection area of the individual conductor to be connected in the drawbar.

Die Anordnung ist somit nicht nur mechanisch kompliziert und aus vielen Teilen bestehend, sondern elektrisch infolge der außerordentlich hohen Zahl von Kontaktstellen mit erheblichen Übergangswiderständen behaftet.The arrangement is therefore not only mechanically complicated and consists of many parts, but is also electrically affected by considerable contact resistance due to the extremely high number of contact points.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, einen Anschlußklemmenblock der gattungsgemäßen Art zu schaffen, der sich durch einen einfachen mechanischen Aufbau sowie durch geringe Übergangswiderstände auszeichnet.The present invention is therefore based on the object of providing a terminal block of the generic type which is distinguished by a simple mechanical structure and by low contact resistances.

Die erfindungsgemäße Lösung besteht darin, daß in dem Unter­teil eine Durchsteckführung für die Flachbandleitung vorgesehen ist, dem Einzelleiteranschlüsse im Anschlußklemmenblock und isolationsdurchdringende Kontakte zugeordnet sind, für die im Unterteil zu der Durchsteckführung verlaufende Führungskanäle vorgesehen sind und die Einzelleiteranschlüsse im Klemmen­block in einem nach dem Flachbandleitungsraster ausgelegten Rasterversatz angeordnet sind.The solution according to the invention consists in that a push-through guide for the ribbon cable is provided in the lower part, to which individual conductor connections in the terminal block and insulation-penetrating contacts are assigned, for which guide channels are provided in the lower part to the push-through guide and the single conductor connections in the terminal block are designed in a manner according to the ribbon cable grid Grid offset are arranged.

Dank dieser Ausgestaltung kommen die bislang erforderliche Leiterplatte sowie der Steckverbinder zwischen der Flachband­leitung und der Leiterplatte mit seinen beiden Elementen voll­ständig in Fortfall. Die Anordnung erhält somit einen stark vereinfachten mechanischen Aufbau und zeichnet sich auch durch eine denkbar geringe Anzahl von Kontaktstellen aus, da jetzt nur noch Kontaktstellen zwischen den direkt kontaktierten Flachbandleitungen und den isolationsdurchdringenden Kontakten sowie ferner im Anschlußklemmenblock die Kontakte zwischen den isolationsdurchdringenden Kontakten und den Zugbügeln der Einzelleiteranschlüsse sowie zwischen den Zugbügeln und den anzuschließenden Einzelleitern vorhanden sind. Die Übergangswider­stände sind demzufolge entsprechend erheblich verringert.Thanks to this configuration, the previously required circuit board and the connector between the ribbon cable and the circuit board with its two elements are completely eliminated. The arrangement thus has a greatly simplified mechanical structure and is also characterized by a very small number of contact points, since now only contact points between the directly contacted ribbon cables and the insulation-penetrating contacts, and also in the terminal block, the contacts between the insulation-penetrating contacts and the tension clamps There are individual conductor connections as well as between the drawbars and the individual conductors to be connected. The contact resistances are consequently considerably reduced.

Durch den am Flachbandleitungsraster orientierten Raster­versatz der Einzelleiteranschlüsse im Klemmenblock baut dieser insgesamt gesehen räumlich sehr kompakt und klein, so daß von daher Unterbringungsprobleme für einen derarti­gen Klemmenblock beispielsweise in Schaltanlagen auf einer Normtragschiene nicht zu befürchten sind.As a result of the grid offset of the individual conductor connections in the terminal block, which is oriented on the ribbon cable grid, the latter is spatially very compact and small, so that there is therefore no need to fear housing problems for such a terminal block, for example in switchgear installations on a standard mounting rail.

Weitere bevorzugte Ausführungsformen eines derartigen Klemmenblockes, die insbesondere auf die weitere Verein­fachung der baulichen Ausgestaltung sowie auf eine weitere Vereinfachung der Anschlußarbeiten bei einem derartigen Klemmenblock gerichtet sind, sind in den Unteransprüchen gekennzeichnet.Further preferred embodiments of such a terminal block, which are aimed in particular at further simplifying the structural design and at further simplifying the connection work in such a terminal block, are characterized in the subclaims.

Bevorzugte Ausführungsbeispiele derartiger Anschlußklemmen­blocks werden nachstehend unter Bezugnahme auf die Zeich­nungen näher beschrieben.Preferred embodiments of such terminal blocks are described below with reference to the drawings.

Der Klemmenblock zum Anschließen von Einzelleitern an Flach­bandleitungen hat ein Unterteil 1, an dem Mittel zu seiner Festsetzung, beispielsweise Rasten 2 zu seiner Verrastung auf einer Normtragschiene vorgesehen sind. Anstelle der Rasten 2 könnten auch Befestigungswinkel oder dergleichen zum Festsetzen, beispielsweise Verschrauben, an ebenen Flächen vorgesehen werden.The terminal block for connecting individual conductors to ribbon cables has a lower part 1 on which means for fixing it, for example detents 2 for locking it on a standard mounting rail, are provided. Instead of the catches 2, fastening brackets or the like could also be provided on flat surfaces for fixing, for example screwing.

Im unteren Bereich des Unterteiles 1 ist eine der Größe, ins­besondere Breite einer anzuschließenden Flachbandleitung 3 angepaßte Durchsteckführung 4 vorgesehen. Aus herstellungs­technischen Gründen kann das Unterteil 1 mehrteilig ausge­bildet sein und kann ein spezielles Innenteil haben, das im wesentlichen die Durchsteckführung 4 definiert, wobei in einem Rahmengehäuse des Unterteiles 1 dann auf der Einführungsseite die Durchsteckführungen 4 offen münden, während die rückwär­tige Rahmenseite des Unterteiles 1, die in Figur 2 zu erkennen ist, geschlossen sein kann, so daß die Flachbandleitung 3 gegen die geschlossene Rückwand als Anschlag mit definierter Einstecktiefe eingeführt werden kann.In the lower region of the lower part 1, a push-through guide 4 is provided which is adapted to the size, in particular the width, of a ribbon cable 3 to be connected. For manufacturing reasons, the lower part 1 can be formed in several parts and can have a special inner part which essentially defines the push-through guide 4, the push-through guides 4 then opening on the insertion side in a frame housing of the lower part 1, while the rear frame side of the lower part 1, which can be seen in Figure 2, can be closed so that the ribbon cable 3 can be inserted against the closed rear wall as a stop with a defined insertion depth.

Abweichend von der vorstehend beschriebenen Ausgestaltung ist es auch möglich, ein Unterteil vorzusehen, das in der Ebene der Durchsteckführung für die Flachbandleitung geteilt ist, wobei die beiden Teilstücke dann lösbar miteinander verbunden sind, beispielsweise im Verhältnis zueinander deckelartig klappbar sind, wobei die zugeklappte Stellung verrastbar oder verriegelbar ist. Bei letzterer Ausgestaltung kann das Einfä­deln der Flachbandleitung in das Unterteil entfallen. Die Flach­bandleitung kann vielmehr bei aufgeklapptem Unterteil in die Führung eingelegt werden, so daß dann auch der Klemmenblock insgesamt an beliebiger Stelle der Erstreckung der Flachband­leitung auf diesem angeordnet werden kann.Deviating from the configuration described above, it is also possible to provide a lower part which is divided in the plane of the push-through guide for the ribbon cable, the two partial parts then being releasably connected to one another, for example being able to be folded like a lid in relation to one another, the closed position being lockable or can be locked. In the latter embodiment, the threading of the ribbon cable into the lower part can be omitted. Rather, the ribbon cable can be inserted into the guide with the lower part unfolded, so that the terminal block as a whole can then be arranged on the ribbon cable at any point along the extension thereof.

Die Anordnung beinhaltet ferner den eigentlichen Klemmenblock 5, in dem die Einzelleiteranschlüsse 6 untergebracht sind. Diese können beispielsweise aus Zugbügeln 7 mit Klemmschrauben 8 ge­bildet sein. Allen Einzelleiteranschlüssen 6 sind nun im Klemmenblock 5 isolationsdurchdringende Kontakte 9 zugeordnet, beispielsweise in Form von an die Zugbügel 5 angeformten, daran befestigten Doppelmesserkontakten,die durch den Klemmen­block 5 nach unten in Richtung auf die Durchsteckführung 4 zu verlaufen. In dem Unterteil 1 sind dabei für alle diese iso­lationsdurchdringenden Kontakte 9 Führungskanäle 10 vorgesehen, wie in Figur 3 gezeigt. Diese Führungskanäle 10 münden dabei zunächst in der Durchsteckführung 4, sind aber auch noch ein wenig über diese hinaus nach unten verlängert, so daß die Doppelmesser nach dem Eindrücken in die Flachbandleitung 3 und die Durchdringung der Isolierung mit entsprechender Kontakt­nahme mit dem betroffenen Leiter der Flachbandleitung bequem Platz haben, wie ebenfalls in Figur 3, die diese Kontaktstellung zeigt, illustriert ist.The arrangement also includes the actual terminal block 5, in which the individual conductor connections 6 are accommodated. These can be formed, for example, from tension clips 7 with clamping screws 8. All individual conductor connections 6 in the terminal block 5 are now assigned contacts 9 which penetrate insulation, for example in the form of molded double-blade contacts which are molded onto the pulling bracket 5 and run downward through the terminal block 5 in the direction of the push-through guide 4. In the lower part 1 9 guide channels 10 are provided for all these insulation penetrating contacts, as shown in Figure 3. This guide channels 10 open out first in the push-through guide 4, but are also extended a little beyond this downwards, so that the double knife after pressing into the ribbon cable 3 and the penetration of the insulation with appropriate contact with the relevant conductor of the ribbon cable convenient Have space, as is also illustrated in Figure 3, which shows this contact position.

In zweckmäßiger Ausgestaltung ist bezüglich der Relativlagen des eigentlichen Klemmenblockes 5 zum Unterteil 1 sowohl eine Vor­verrastung wie eine Endverrastung vorgesehen. Hierzu kann bei­spielsweise, wie in Figur 1 illustriert, am eigentlichen Klemmenblock 5 auf zwei gegenüberliegenden Seiten je eine Rast­lippe 11 angeformt sein, für die am entsprechenden Innenwandungs­bereich des Unterteiles 1 zwei abständig übereinander angeord­nete Rastaufnahmen 12 und 13 vorgesehen sind. Herstellerseitig kann die Anordnung so ausgeliefert werden, daß die Rastlippe 11 des eigentlichen Klemmenblockes 5 zunächst in der oberen Rast­aufnahme 12 verrastet ist, in welcher Stellung dann die Doppel­messer der isolationsdurchdringenden Kontakte 9 noch nicht an die Durchsteckführung 4 heranreichen. Wird dann in dieser vor­montierten Stellung mit Hilfe eines Spezialwerkzeuges der eigent­liche Klemmenblock 5 im Unterteil 1 nach unten gedrückt, durch­dringen die Doppelmesser der isolationsdurchdringenden Kontakte 9 die Isolierungen der Flachbandleitung 3 unter Kontaktierung, bei gleichzeitiger Verrastung dieser Endstellung durch Einschnappen der Rastlippe 11 in der unteren Rastaufnahme 13.In an expedient embodiment, with respect to the relative positions of the actual terminal block 5 to the lower part 1, both a pre-locking and an end locking are provided. For this purpose, for example, as illustrated in FIG. 1, a latching lip 11 can be formed on the actual terminal block 5 on two opposite sides, for which two latching receptacles 12 and 13 arranged one above the other are provided on the corresponding inner wall area of the lower part 1. The arrangement can be supplied by the manufacturer such that the locking lip 11 of the actual terminal block 5 is initially locked in the upper locking receptacle 12, in which position the double blades of the insulation-penetrating contacts 9 do not yet reach the push-through guide 4. If the actual terminal block 5 in the lower part 1 is then pressed down in this preassembled position with the aid of a special tool, the double blades of the insulation-penetrating contacts 9 penetrate the insulation of the ribbon cable 3 while making contact simultaneous locking of this end position by snapping the locking lip 11 in the lower locking receptacle 13.

Insbesondere zur Erzielung einer raumsparenden kompakten Bau­weise auch im Hinblick darauf, daß derartige Klemmenblocks zum Anschluß von Einzelleitern an Flachbandleitungen häufig im Rahmen von Schaltanlagen mit ihren beengten räumlichen Verhält­nissen Einsatz finden, sind die Einzelleiteranschlüsse 6 im eigentlichen Klemmenblock 5 in einem Rasterversatz angeordnet, der nach dem vorgegebenen Flachbandleitungsraster ausgelegt ist. Bei grundsätzlich freier Anzahl für die Unterbringung von Einzel­leiteranschlüssen 6 mit ihren zugeordneten isolationsdurch­dringenden Kontakten 9 innerhalb eines einzelnen Rasterversatzes hat sich in der Praxis die Zusammenfassung von vier Einzelleiter­anschlüssen 6 mit ihren zugeordneten isolationsdurchdringenden Kontakten 9 in einem derartigen Rasterversatz als sehr zweck­mäßig erwiesen. Die Figuren 2 und 4 illustrieren einen derarti­gen Rasterversatz. Mit a sei das vorgegebene Flachbandleitungs­raster gekennzeichnet. Innerhalb eines Rasterversatzes beträgt der Versatz zwischen dem ersten Einzelleiteranschluß 6 und den weiteren drei Einzelleiteranschlüssen 6 dann jeweils a, 2a und 3a, wobei sich die Breite eines Rasterversatzelementes insgesamt bzw. einer Rasterversatzgruppe auf 4a beläuft. Das derzeit handelsübliche Flachbandleitungsraster beträgt 1,27 mm. Inner­halb der Rasterversatzgruppe lassen sich die Versatzmaße von 1,27 mm, sowie dem Zweifachen und dem Dreifachen davon, noch gut verwirklichen und die Gesamtbreite eines einzelnen Raster­versatzelementes bzw. einer Rasterversatzgruppe beträgt dann 5,08 mm und damit eine Breite, bei der sich die gängige Ausge­staltung der Einzelleiteranschlüsse in Form von Schrauban­schlüssen oder Federanschlüssen noch verwirklichen läßt.In particular to achieve a space-saving, compact design, also with regard to the fact that such terminal blocks for connecting single conductors to ribbon cables are often used in the context of switchgear with their cramped spatial conditions, the individual conductor connections 6 in the actual terminal block 5 are arranged in a grid offset, which according to predetermined ribbon cable grid is designed. With a basically free number for accommodating single-conductor connections 6 with their assigned insulation-penetrating contacts 9 within a single grid offset, the combination of four single-conductor connections 6 with their assigned insulation-penetrating contacts 9 in such a grid offset has proven to be very useful in practice. Figures 2 and 4 illustrate such a grid offset. Let a be the specified ribbon cable grid. Within a grid offset, the offset between the first individual conductor connection 6 and the further three individual conductor connections 6 is then a, 2a and 3a, the width of a grid offset element as a whole or of a grid offset group being 4a. The currently standard ribbon cable grid is 1.27 mm. Within the grid offset group, the offset dimensions of 1.27 mm, as well as double and triple thereof, can still be implemented well and the total width of a single grid offset element or a grid offset group is then 5.08 mm and thus a width at which the usual Design of the single conductor connections in the form of screw connections or spring connections can still be realized.

Bei der Ausführungsform nach Figur 2 ist ein eigentlicher Klemmenblock 5 illustriert, der entweder insgesamt einstückig aus Isoliermaterial gebildet ist, oder bei dem zumindest die vier hintereinander versetzt liegenden Reihen entsprechend der gewählten vier Versatzebenen einstückige und anschließend montierte Elemente sind.In the embodiment according to FIG. 2, an actual terminal block 5 is illustrated, which is either formed as a whole in one piece from insulating material, or in which at least the four rows which are offset one behind the other correspond to FIG selected four offset levels are one-piece and then assembled elements.

Gemäß einer weiteren, in Figur 4 angedeuteten und illustrier­ten Ausführungsform kann es jedoch auch sehr zweckmäßig sein, den Anschlußklemmenblock 5 aus Einzelscheiben 14 aufzubauen, wobei jede Einzelscheibe dann die vier in entsprechendem Raster versetzt liegenden Einzelanschlüsse 6 mit den zuge­ordneten isolationsdurchdringenden Kontakten 9 beinhaltet.According to a further embodiment, which is indicated and illustrated in FIG. 4, it can also be very expedient to construct the terminal block 5 from individual disks 14, each individual disk then containing the four individual connections 6, offset in a corresponding grid, with the associated insulation-penetrating contacts 9.

Am rechten und am linken Ende der Anreihung eines derart aus Einzelscheiben aufgebauten Klemmenblockes 5 werden dann ent­weder als spezielle Endstücke ausgebildete Einzelscheiben eingesetzt, die einen Materialausgleich für den Versatz haben, oder es werden, wenn man hier einen glattwandigen Abschluß haben will, beispielsweise spezielle Endstücke 15 zur seitli­chen Begrenzung der Anreihung vorgesehen.At the right and at the left end of the arrangement of a terminal block 5 constructed from individual disks, either individual disks designed as special end pieces are used which have a material compensation for the offset, or, if one wants to have a smooth-walled end, for example special end pieces 15 intended for lateral limitation of the baying.

In den dargestellten Ausführungsbeispielen nach den Figuren 1 und 2 sind im Rasterversatz angeordnete Einzelleiteranschlüsse 6 des Anschlußklemmenblockes 5 in einer Höhenlage verblieben. Abweichend von diesem Ausführungsbeispiel besteht auch die Möglichkeit, innerhalb der vier Versatzebenen auch noch einen Versatz in der Höhe von Ebene zu Ebene durchzuführen, derart, daß beispielsweise von Ebene zu Ebene die jeweils in den Ebenen liegenden Einzelleiteranschlüsse 6 höher liegen als in der vor­hergehenden Ebene. Dies kann das Anschließen der Einzelleiter in den zahlreichen Einzelleiteranschlüssen 6 erleichtern.In the illustrated exemplary embodiments according to FIGS. 1 and 2, individual conductor connections 6 of the terminal block 5 arranged in a grid offset have remained at a high position. Deviating from this exemplary embodiment, there is also the possibility of performing an offset in the height from level to level within the four offset levels, such that, for example from level to level, the individual conductor connections 6 lying in the levels are higher than in the previous level. This can facilitate the connection of the individual conductors in the numerous individual conductor connections 6.
