Description

Beschreibungdescription
Elektromagnetisches Schaltgerät, insbesondere SchützElectromagnetic switching device, in particular contactor
Die Erfindung betrifft ein elektromagnetisches Schaltgerät , insbesondere ein Schütz .The invention relates to an electromagnetic switching device, in particular a contactor.
Zur Ansteuerung eines Schütz muss an dem Schützantrieb eine Spannung angelegt werden . Hierzu ist es bekannt, mindestens zwei fest am Schützgehäuse angebrachte Spulenanschlussklemmen vorzusehen . Da Schütze auf unterschiedliche Art und Weise mit anderen Schaltgeräten kombiniert werden können, werden diese Spulenanschlussklemmen häufig verdeckt, so dass sie teilweise an anderen Stellen des Schützgehäuses nochmals vorgesehen sind . Insbesondere wenn die Spulenanschlussklemmen neben den Anschlussklemmen für die Hauptstrombahn oder Hilfsstrombahn angeordnet sind, damit der Spulenanschluss von vorne zugänglich ist, ist bei einer Kombination mit anderen Schaltgeräten mindestens eine Spulenanschlussklemme schlechter zugänglich . Neben diesen Geräten, bei denen die Spulenanschlussklemmen in einer Anschlussebene mit den Haupt- und Hilfsleiterklemmen liegen, sind Schaltgeräte bekannt , bei denen die Spulenanschlussklemmen unter den Hauptleiterklemmen angeordnet sind . Bei derartigen Schaltgeräten ist die Zugänglichkeit aufgrund des noch komplexeren Aufbaus nochmals erschwert, wenn derTo control a contactor, a voltage must be applied to the contactor drive. For this purpose, it is known to provide at least two fixed to the contactor housing coil terminals. Since contactors can be combined in different ways with other switching devices, these coil terminals are often covered, so that they are partially provided elsewhere in the contactor housing again. In particular, if the coil terminals are arranged next to the connection terminals for the main current flow or auxiliary current path, so that the coil terminal is accessible from the front, at least one coil terminal is less accessible when combined with other switching devices. In addition to these devices, where the coil terminals are located in a terminal level with the main and auxiliary conductor terminals, switching devices are known in which the coil terminals are located under the main conductor terminals. In such switching devices accessibility is further complicated due to the even more complex structure when the
Hauptleiter angeschlossen ist . Bei einem Anbau zusätzlicher Schaltgeräte, beispielsweise eines Leistungsschalters und/oder eines Überlastrelais , sind die Spulenanschlüsse in diesen Fällen überhaupt nicht mehr zugänglich .Main conductor is connected. When attaching additional switching devices, such as a circuit breaker and / or an overload relay, the coil terminals in these cases are no longer accessible.
Eine Aufgabe der Erfindung ist es, die Handhabbarkeit von Spulenanschlüssen bei einem elektromagnetischen Schaltgerät zu verbessern .An object of the invention is to improve the manageability of coil terminals in an electromagnetic switching device.
Diese Aufgabe wird durch ein elektromagnetisches Schaltgerät nach Anspruch 1 gelöst . Danach ist ein elektromagnetisches Schaltgerät mit einer Anzahl von Hilfsschalteranschlüssen und einem Spulenanschlussklemmenblock mit wenigstens einer Spu- lenanschlussklemme vorgesehen, wobei wenigstens eine Spulen- anschlussklemme des Spulenanschlussklemmenblocks in einer Ebene mit einem Hilfsschalteranschluss des Schaltgerätes liegt . Dadurch wird gewährleistet, dass die Spulenanschluss- klemme zusammen mit den Hilfsanschlüssen, beispielsweise mit Hilfe eines Steckers kontaktiert werden kann . Durch den Einsatz eines gemeinsamen Steckers wird der Anschluss und damit die Handhabung des Schaltgerätes wesentlich vereinfacht .This object is achieved by an electromagnetic switching device according to claim 1. Thereafter, an electromagnetic switching device with a number of auxiliary switch terminals and a coil terminal block provided with at least one coil len terminal, wherein at least one coil terminal of the coil terminal block is in a plane with an auxiliary switch terminal of the switching device. This ensures that the coil terminal can be contacted together with the auxiliary terminals, for example by means of a plug. Through the use of a common connector, the connection and thus the handling of the switching device is much easier.
Mit der Erfindung können Spulenanschlüsse unabhängig von verschiedenen Aufbauten und Anschlusstechniken flexibel und im Vergleich zu den bekannten Lösungen wesentlich besser zugänglich bereitgestellt werden .With the invention, coil terminals, irrespective of various structures and connection techniques, can be provided flexibly and in a much more accessible manner compared with the known solutions.
Vorteilhafte Ausführungsformen der Erfindung sind in den Unteransprüchen angegeben .Advantageous embodiments of the invention are specified in the subclaims.
Besonders vorteilhaft ist eine Anordnung des Spulenanschlus- ses an der Vorderseite des Schaltgerätes . Spulenanschluss- klemmen können dann universell derart angeordnet werden, dass eine Zugänglichkeit von oben, von unten und von vorn realisierbar ist , ohne das Spulenanschlussklemmen an mehreren verschiedenen Orten vorgesehen werden müssen . Somit wird nicht nur der Aufbau von Schaltgeräten stark vereinfacht . Auch die Handhabbarkeit eines derartigen Schaltgerätes ist wesentlich verbessert , da ein Anschluss von vorn möglich ist .Particularly advantageous is an arrangement of the coil connection on the front side of the switching device. Coil connection terminals can then be arranged universally in such a way that accessibility from above, from below and from the front can be realized without the coil connection terminals having to be provided at several different locations. Thus, not only the construction of switching devices is greatly simplified. The handling of such a switching device is significantly improved because a connection from the front is possible.
Mit der Verwendung eines von vorn elektrisch und mechanisch steckbaren Spulenanschlussklemmenblocks wird eine besonders einfache Handhabung erreicht . Durch Herstellen einer einzigen Steckverbindung wird der Spulenanschlussklemmenblock nicht nur mechanisch, sondern auch elektrisch mit dem Schaltgerät verbunden . Aufwändige Zusatzverbindungen entfallen .With the use of a front electrically and mechanically pluggable coil terminal block a particularly simple handling is achieved. By making a single connector, the coil terminal block is not only mechanically but also electrically connected to the switching device. Elaborate additional connections omitted.
Der Spulenanschlussklemmenblock ermöglicht bei einer beliebigen Aufbauweise des Schaltgerätes eine optimale Zugänglich- keit zu den Klemmen des Spulenanschlusses und verhindert damit , dass Drähte über andere Schaltgeräte geführt werden müssen .The coil connection terminal block allows optimal accessibility for any configuration of the switching device. To the terminals of the coil terminal and thus prevents wires must be routed through other switching devices.
Dabei können Klemmen mit unterschiedlichen Anschlusstechniken, beispielsweise Schraubanschluss , Schneidklemme, Push-in- Technik, Käfigzugfeder usw. , am Schaltgerät gesteckt werden . Handelt es sich bei dem Schaltgerät um ein Schütz, bei dem beispielsweise die Hauptleiterklemmen in Schraubtechnik aus- geführt sind, können alle möglichen Anschlussvarianten, einschließlich der Hilfs- und Steuerleiter, gesteckt werden . Das Schaltgerät ist mit anderen Worten für einen Steckanschluss bei Hilfs- und Steuerleiter vorbereitet .In this case, terminals with different connection techniques, such as screw connection, insulation displacement terminal, push-in technology, cage tension spring, etc., can be plugged into the switching device. If the switching device is a contactor in which, for example, the main conductor terminals are screwed, all possible connection variants, including the auxiliary and control conductors, can be plugged. In other words, the switching device is prepared for a plug-in connection at auxiliary and control conductors.
Mit Hilfe der Erfindung ist es möglich, die Anzahl der verschiedenen benötigten Bauformen bei Schaltgeräten zu verringern . Selbst wenn die Schaltgeräte unterschiedliche Anschlusstechniken bei den Steuerklemmen vorsehen, können sie mit Hilfe der Erfindung untereinander kombiniert werden . Auf- grund der Steckverbindung ist ein Austausch des Spulenan- schlussklemmenblocks und damit eine Änderung der Anschlusstechnik auf einfache Art und Weise möglich und kann auch vom Anwender ausgeführt werden .With the aid of the invention, it is possible to reduce the number of different required designs for switching devices. Even if the switching devices provide different connection techniques at the control terminals, they can be combined with each other by means of the invention. Due to the plug connection, replacement of the coil connection terminal block and thus a change in the connection technology is possible in a simple way and can also be carried out by the user.
Vorzugsweise ist der von vorn steckbare Spulenanschlussklem- menblock als alleiniger Spulenanschluss vorgesehen . Weitere Spulenanschlüsse in Richtung der oberen Anschlussseite beziehungsweise in Richtung der unteren Anschlussseite des Schaltgerätes sind mit anderen Worten nicht vorgesehen . Dadurch wird der konstruktive Aufbau des Schaltgerätes stark vereinfacht, ohne dass die Funktionalität des Schaltgerätes darunter leidet . Selbstverständlich ist es ebenfalls möglich, den erfindungsgemäßen Spulenanschlussklemmenblock als Ergänzung zu vorhandenen ortsfesten Spulenanschlussklemmen einzusetzen . Besonders vorteilhaft ist es, wenn die Spulenanschlussklemmen in Stufen übereinander angeordnet sind. Hierdurch können unterschiedliche Kontaktierungsebenen definiert werden .Preferably, the front insertable Spulenanschlussklem- block is provided as the sole coil connection. Further coil connections in the direction of the upper connection side or in the direction of the lower connection side of the switching device are not provided in other words. As a result, the structural design of the switching device is greatly simplified, without the functionality of the switching device suffers. Of course, it is also possible to use the coil terminal block according to the invention as a supplement to existing stationary coil terminals. It when the coil terminals are arranged in stages one above the other is particularly advantageous. As a result, different contacting levels can be defined.
Ein Spulenanschlussklemmenblock mit in Stufen übereinander angeordneten Spulenanschlussklemmen kann vorzugsweise in seiner Anschlussrichtung gewendet werden . Der Spulenanschlussklemmenblock ist dann j e nach Anordnung am Schaltgerät sowohl von unten als auch von oben kontaktierbar . Mit anderen Worten ist es beispielsweise möglich, den Spulenanschlussklemmenblock mit seiner höher gelegenen Stufe in Richtung der oberen Anschlussseite oder in Richtung der unteren Anschlussseite des Schaltgerätes einzusetzen . Hierdurch wird die universelle Einsetzbarkeit des erfindungsgemäßen Spulenanschlussklemmen- blocks nochmals verbessert . Je nachdem, welche Gerätekombinationen oder Anschlussvarianten gewünscht sind, können die unterschiedlichen Anschlussebenen nach oben oder unten ausgerichtet sein .A coil connection terminal block with coil terminals arranged one above the other in stages can preferably be turned in its connection direction. The coil terminal block is then j e after contact with the switching device both from below and from above contacted. In other words, it is possible, for example, to insert the coil terminal block with its higher level toward the upper terminal side or toward the lower terminal side of the switching device. As a result, the universal applicability of the Spulenanschlussklemmen- block invention is further improved. Depending on which device combinations or connection variants are desired, the different connection levels can be aligned upwards or downwards.

FIG 1 zeigt einen aus dem Stand der Technik bekannten Schütz 101 , welcher mit seiner Rückseite 102 nach unten und mit sei- ner Vorderseite 103 nach oben dargestellt ist . Auf der Vorderseite 103 des Schütz 101 ist in Richtung der Schützoberseite 104 eine obere Anschlussreihe 105 und in Richtung der Schützunterseite 106 eine untere Anschlussreihe 107 vorgesehen . Die beiden Anschlussreihen 105, 107 umfassen dabei j e- weils drei Hauptstromanschlüsse 108 , einen Hilfsschalteran- schluss 109 und einen Spulenanschluss 110. Dabei liegt die obere Anschlussreihe 105 und die untere Anschlussreihe 107 in einer Ebene . Hauptstrom-, Hilfsschalter- und Spulenanschluss 108 , 109, 110 sind als Schraubanschlüsse ausgebildet . Die obere Anschlussreihe 105 dient dabei als Eingangsseite und die untere Anschlussreihe 107 als Abgangsseite .1 shows a known from the prior art contactor 101, which is shown with its rear side 102 down and with its front side 103 facing upwards. On the front side 103 of the contactor 101, an upper terminal row 105 is provided in the direction of the contactor upper side 104, and a lower terminal row 107 is provided in the direction of the contactor lower side 106. In each case, the two terminal rows 105, 107 comprise three main current terminals 108, one auxiliary switch terminal 109 and one coil terminal 110. The upper terminal row 105 and the lower terminal row 107 lie in one plane. Main current, auxiliary switch and coil terminal 108, 109, 110 are designed as screw connections. The upper terminal row 105 serves as the input side and the lower terminal row 107 as the outlet side.
Bei dem in FIG 2 gezeigten Schütz 111 , welches ebenfalls aus dem Stand der Technik bekannt ist, sind auf der gleichen Bau- breite, wie sie der Schütz 101 aus FIG 1 aufweist, anstelle von fünf jeweils nur drei Anschlüsse vorgesehen, so dass größere Anschlussquerschnitte zum Schalten von höheren Strömen verwendet werden können . Da die Hauptstromanschlüsse 108 die gesamte Baubreite des Schütz 111 einnehmen, sind auf der Vorderseite 103 des Schütz 111 vier Aufnahmen 112 für zusätzliche Hilfsschalter (nicht abgebildet ) vorgesehen . Hilfs- schalter können j edoch auch seitlich an den hierfür vorgesehenen Aussparungen 113 des Schützgehäuses angeklemmt werden . Zum Anschluss der Spulen sind an der Schützunterseite 106 als auch an der Schützoberseite 104 j eweils zwei Spulenanschlüsse 114 vorgesehen, die diagonal durch das Schützgehäuse leitend miteinander verbunden sind . Ist nun beispielsweise ein sol- eher Schütz 111 an seiner Unterseite 106 oder seiner Oberseite 104 mit einem weiteren Schaltgerät oder dergleichen verbunden, dann sind einzelne Spulenanschlüsse 114 vollständig verdeckt derart, dass entweder Spuleneingang oder Spulenaus- gang nicht mehr kontaktiert werden können .In the case of the contactor 111 shown in FIG. 2, which is likewise known from the prior art, instead of five, only three connections each are provided on the same width as that of the contactor 101 from FIG. 1, so that larger connection cross-sections are provided can be used to switch higher currents. Since the main power connections 108 occupy the entire width of the contactor 111, four receptacles 112 for additional auxiliary switches (not shown) are provided on the front side 103 of the contactor 111. However, auxiliary switches can also be clamped laterally on the recesses 113 of the contactor housing provided for this purpose. To connect the coils, two coil terminals 114 are provided on the contactor lower side 106 and on the contactor upper side 104, respectively, which are conductively connected to one another diagonally through the contactor housing. If, for example, a sol- rather contactor 111 is connected on its underside 106 or its upper side 104 to a further switching device or the like, then individual coil terminals 114 are completely concealed in such a way that either coil input or coil output can no longer be contacted.
FIG 3 bis 6 zeigen erfindungsgemäße Spulenanschlussklemmen- blöcke 1 , 2 , 3, 4. Der in FIG 3 dargestellte Spulenanschluss- klemmenblock 1 weist zwei Spulenanschlussklemmen 5, 6 auf, die in zwei übereinander angeordneten Anschlussebenen I 1 8 stufenartig angeordnet sind. An seiner Unterseite 9 weist der Spulenanschlussklemmenblock 1 zwei Steckkontakte 10 in Form von Kontaktstiften auf . Diese dienen der gleichzeitigen mechanischen und elektrischen Steckkontaktierung des Spulen- anschlussklemmenblocks 1 mit einem erfindungsgemäßen Schütz . Die Spulenanschlussklemmen 5, 6 können mit Klemmverbindungen und/oder Steckverbindungen und/oder Schraubverbindungen ( FIG 6) ausgeführt sein . Alternativ ist die Anordnung von Feder- zugklemmen ( FIG 5 ) möglich . Im einfachsten Fall sind die Steckkontakte 10 an der Unterseite 9 des Spulenanschlussklem- menblocks 2 nach oben hin verlängert und ragen als entsprechende Anschlusssteckkontakte 11 aus der Oberseite 12 des Spulenanschlussklemmenblocks 2 hinaus ( FIG 4 ) . Selbstverständlich ist es ebenfalls möglich, dass mehr als zwei Spu- lenanschlussklemmen in einem Spulenanschlussklemmenblock 3 , 4 integriert sind. So ist es beispielsweise möglich, dass j eweils zwei Anschlusskontakte eingangsseitig und abgangsseitig vorgesehen sind ( FIG 5 und 6) . In Variation mit beliebigen Abstufungen zur Bildung verschiedener Anschlussebenen 7 , 8 ergeben sich dadurch eine Vielzahl von Anschlussvarianten . Die Anschlussrichtungen sind in FIG 3 bis 6 durch Pfeile A dargestellt . Eine alternative Anschlussmöglichkeit in FIG 3 zeigt Pfeil A' .3 to 6 show coil terminal blocks 1, 2, 3, 4 according to the invention. The coil terminal block 1 shown in FIG. 3 has two coil terminals 5, 6, which are arranged stepwise in two connection layers I 1 8 arranged one above the other. On its underside 9, the coil terminal block 1 has two plug contacts 10 in the form of contact pins. These serve the simultaneous mechanical and electrical plug-in contacting of the coil terminal block 1 with a contactor according to the invention. The coil connection terminals 5, 6 can be designed with clamping connections and / or plug connections and / or screw connections (FIG. 6). Alternatively, the arrangement of spring tension terminals (FIG 5) is possible. In the simplest case, the plug contacts 10 on the underside 9 of the Spulenanschlussklem- block 2 are extended upward and protrude as corresponding terminal plug contacts 11 from the top 12 of the coil terminal block 2 addition (Figure 4). Of course, it is also possible that more than two coil connection terminals are integrated in a coil connection terminal block 3, 4. For example, it is possible that in each case two connection contacts are provided on the input side and on the output side (FIGS. 5 and 6). In variation with any gradations to form different connection levels 7, 8, this results in a variety of connection variants. The connection directions are shown in FIGS. 3 to 6 by arrows A. An alternative connection option in FIG. 3 shows arrow A '.
In FIG 7 ist ein Beispiel eines erfindungsgemäßen Schütz 15 abgebildet . Neben den bereits aus FIG 2 bekannten drei ein- gangsseitigen Hauptstromanschlüssen 16 in einer oberen An- Schlussreihe 17 und drei abgangsseitigen Hauptstromanschlüssen 18 in einer unteren Anschlussreihe 19 und drei Aufnahmen 20 für zusätzliche Hilfsschalter (nicht abgebildet) , ist an der Vorderseite 21 des Schütz 15 eine zusätzliche Steckerauf- nähme 22 zur Ausbildung einer Steckverbindung vorgesehen . Die Aufnahme 22 weist dabei zwei Aufnahmeöffnungen 23 zur Aufnahme der Steckkontakte 10 eines Spulenanschlussklemmenblocks 1, 2 , 3 , 4 auf derart, dass bei einem eingesteckten Spulenan- schlussklemmenblock 1 , 2 , 3, 4 dessen Steckkontakte 10 in ei- ner elektrischen Verbindung mit den Spulenanschlüssen 24 an der Schützoberseite 25 einerseits und der Schützunters'eite 26 andererseits bestehen . Diese Verbindung kann beispielsweise durch ein Blechteil 27 , einen Draht oder dergleichen von der Steckeraufnahme 22 zur Spule geschaffen werden .FIG. 7 shows an example of a contactor 15 according to the invention. In addition to the already known from FIG 2 three input-side main power connections 16 in an upper End row 17 and three outlet-side main power connections 18 in a lower terminal row 19 and three receptacles 20 for additional auxiliary switch (not shown), is provided on the front side 21 of the contactor 15, an additional plug-receiving member 22 for forming a plug connection. The receptacle 22 in this case has two receiving openings 23 for receiving the plug contacts 10 of a Spulenanschlussklemmenblocks 1, 2, 3, 4 in such a way that in an inserted coil terminal block terminal block 1, 2, 3, 4 whose plug contacts 10 in an electrical connection with the Coil terminals 24 on the contactor upper side 25 on the one hand and the Schützunters ' eite 26 on the other hand. This connection can be created for example by a sheet metal part 27, a wire or the like from the connector receptacle 22 to the coil.
FIG 8 zeigt den Schütz 15 aus FIG 7 mit aufgesetztem Spulen- anschlussklemmenblock 1. Der Spulenanschlussklemmenblock 1 mit seinen Steckkontakten 10 und die Steckeraufnahme 22 an der Vorderseite 21 des Schütz 15 sind dabei derart ausgebil- det , dass der Spulenanschlussklemmenblock 1 mit seiner höher gelegenen Stufe 8 in Richtung der oberen Anschlussreihe 17 (wie abgebildet ) eingesetzt werden kann . Somit sind die Spu- lenanschlussklemmen 5 , 6 von unten ( Pfeil A) zugänglich . Darüber hinaus ist es ebenso möglich, die Spulenanschluss- klemmen 5, 6 bei der in FIG 8 gezeigten Montageart von oben ( Pfeil B) anzuschließen .FIG. 8 shows the contactor 15 from FIG. 7 with the coil connection terminal block 1 attached. The coil terminal block 1 with its plug contacts 10 and the plug receptacle 22 on the front side 21 of the contactor 15 are designed in such a way that the coil terminal block 1 has its higher level 8 in the direction of the upper row of terminals 17 (as shown) can be used. Thus, the coil connection terminals 5, 6 are accessible from below (arrow A). Moreover, it is also possible to connect the coil connection terminals 5, 6 in the manner of installation shown in FIG. 8 from above (arrow B).
Alternativ dazu kann j edoch der Spulenanschlussklemmenblock 1 mit seiner höher gelegenen Stufe 8 auch (um 180 ° gedreht ) in Richtung der unteren Anschlussreihe 19 des Schütz 15 eingesetzt werden . Somit ist sichergestellt, dass die Spulenan- schlussklemmen 5 , 6 auch von oben ( Pfeil B) zugänglich sind . Darüber hinaus ist es ebenso möglich, die Spulenanschluss- klemmen 5, 6 bei dieser Montageart von unten ( Pfeil A) anzu- schließen . Aufgrund der vielen Anschlussvarianten ergibt sich für den Spulenanschlussklemmenblock eine Vielzahl von Einsatzmöglichkeiten . Gleichzeitig hebt der Spulenanschlussklemmenblock 1 wenigstens einzelne Spulenanschlussklemmen 6 in die Ebene der An- schlussklemmen 30 montierter frontseitiger Hilfsschalter- blöcke 31 , wie sie beispielhaft in FIG 9 abgebildet ist . In diesem Fall können die eingangsseitigen, oberen Anschlussklemmen 30 der frontseitigen Hilfsschalterblöcke 31 zusammen mit der höher gelegenen, oberen Anschlussebene 8 des Spulen- anschlussklemmenblocks 1 über einen gemeinsamen Stecker (nicht abgebildet) kontaktiert werden, was die Zugänglichkeit erleichtert .Alternatively, however, the coil connection terminal block 1 with its higher stage 8 can also be used (rotated by 180 °) in the direction of the lower connection row 19 of the contactor 15. This ensures that the coil connection terminals 5, 6 are also accessible from above (arrow B). In addition, it is also possible to connect the coil connection terminals 5, 6 in this type of mounting from below (arrow A). Due to the many connection variants, the coil terminal block offers a multitude of possible applications. At the same time, the coil connection terminal block 1 raises at least individual coil connection terminals 6 in the plane of the connection terminals 30 of mounted front-side auxiliary switch blocks 31, as illustrated by way of example in FIG. In this case, the input side upper terminals 30 of the front auxiliary switch blocks 31 can be contacted together with the higher upper terminal plane 8 of the coil terminal block 1 via a common plug (not shown), which facilitates accessibility.
FIG 10 zeigt eine schematische Darstellung einer Kombination eines Leistungsschalters 36 und eines erfindungsgemäßen Schütz 15. Der Schütz 15 ist dabei unterhalb des Leistungs- Schalters 36 angeordnet und mit diesem verbunden . Mit anderen Worten grenzt der Leistungsschalter 36 an die, Oberseite 25 des Schütz 15 an . Damit das Handbedienteil 37 des Leistungsschalters 36 frei zugänglich ist und nicht von Leitungen verdeckt wird, ist ein Anschluss des Schützes 15 von unten, also aus Richtung seiner Unterseite 26, erforderlich . Hierbei wird ein frontseitiger Hilfsschalterblock (nicht abgebildet ) mit den Anschlussklemmen nach unten verwendet . Der Spulenanschlussklemmenblock 1 wird so auf die Vorderseite 21 des Schütz 15 aufgesetzt, dass die Anschlussklemmen 5 , 6 nach un- ten zeigen . Mit anderen Worten werden alle Hilfsleitungen10 shows a schematic representation of a combination of a circuit breaker 36 and a contactor 15 according to the invention. The contactor 15 is arranged below the power switch 36 and connected thereto. In other words, the power switch 36 adjoins the top 25 of the contactor 15. Thus, the hand control unit 37 of the circuit breaker 36 is freely accessible and is not covered by lines, a connection of the contactor 15 from below, ie from the direction of its bottom 26 is required. This uses a front auxiliary switch block (not shown) with the terminals down. The coil terminal block 1 is placed on the front side 21 of the contactor 15 so that the terminals 5, 6 point downward. In other words, all auxiliary lines
(nicht abgebildet) zum Schütz 15 von unten an diesen herangeführt, da die obere Eingangsseite des Schütz 15 wegen des benachbarten Leistungsschalters 36 nicht genutzt werden kann . Die Anschlussrichtung ist durch Pfeil A dargestellt .(not shown) to the contactor 15 brought from below to this, since the upper input side of the contactor 15 can not be used because of the adjacent circuit breaker 36. The connection direction is shown by arrow A.
In FIG 11 ist eine schematische Darstellung einer Kombination eines Schütz 15 mit einem Überlastrelais 39 abgebildet . Das Überlastrelais 39 ist dabei mechanisch abgangsseitig, also an der Unterseite 26 des Schütz 15 angeordnet . Der Spulenan- schlussklemmenblock 1 ist mit seiner tiefer gelegenen Anschlussstufe 7 in Richtung der Schützoberseite 25 , also ein- gangsseitig, angeordnet . Von dort wird er über einen Draht (nicht abgebildet) kontaktiert . Mit anderen Worten werden Hilfsleiter und Spule von oben angeschlossen. Der frontseitige Hilfsschalterblock (nicht abgebildet) wird mit den Anschlussklemmen nach oben verwendet . Der Spulenanschlussklem- menblock 1 ist also derart gedreht, dass die Anschlussklemmen 5, 6 nach oben zeigen, so dass alle Hilfsleitungen zum Schütz 15 von oben angeschlossen werden . Die Anschlussrichtung ist durch Pfeil A dargestellt .FIG. 11 shows a schematic representation of a combination of a contactor 15 with an overload relay 39. The overload relay 39 is on the mechanical side of the output, that is arranged on the bottom 26 of the contactor 15. The coil connection terminal block 1 is arranged with its lower connection stage 7 in the direction of the contactor upper side 25, that is to say on the input side. From there he will be over a wire (not shown) contacted. In other words, the auxiliary conductor and coil are connected from above. The front auxiliary switch block (not shown) is used with the terminals up. The Spulenanschlussklem- block 1 is thus rotated so that the terminals 5, 6 show upward, so that all auxiliary lines are connected to the contactor 15 from above. The connection direction is shown by arrow A.
FIG 12 zeigt schließlich eine schematische Darstellung einer Kombination von Leistungsschalter 36, Schütz 15 und Überlastrelais 39. Bei dieser Kombination sind bei den meisten bekannten Schützen die Spulenanschlüsse sowohl oben als auch unten verdeckt . Durch den Einsatz des erfindungsgemäßen Spu- lenanschlussklemmenblocks 1 wird die Zugänglichkeit der Spulenanschlüsse gewahrt . Der frontseitige Hilfsschalterblock (nicht abgebildet) wird mit den Anschlussklemmen nach unten verwendet . Der Spulenanschlussklemmenblock 1 wird ebenfalls so gedreht , dass die Anschlussklemmen 5 , 6 nach unten zeigen, so dass alle Hilfsleitungen zum Schütz 15 von unten angeschlossen werden . Das Handbedienteil 37 des Leistungsschalters 36 bleibt somit frei . Mit der vorliegenden Erfindung wird eine einfache Kontaktierbarkeit bei dieser Kombination überhaupt erst möglich . Darüber hinaus ergibt sich eine va- riabel wählbare Leitungsführung über nur ein Gerät, wobei vorzugsweise eine Leitungsführung über das Überlastrelais 36 gewählt wird. Die Anschlussrichtung ist durch Pfeil A dargestellt . Finally, FIG. 12 shows a schematic representation of a combination of power switch 36, contactor 15 and overload relay 39. In this combination, in most known contactors the coil connections are concealed both above and below. The use of the coil connection terminal block 1 according to the invention ensures the accessibility of the coil connections. The front auxiliary switch block (not shown) is used with the terminals down. The coil terminal block 1 is also rotated so that the terminals 5, 6 point down so that all the auxiliary lines to the contactor 15 are connected from below. The manual control unit 37 of the circuit breaker 36 thus remains free. With the present invention, a simple contactability in this combination is possible at all. In addition, there is a variably selectable cable routing over only one device, with preferably a cable routing over the overload relay 36 is selected. The connection direction is shown by arrow A.
