The plug device engages from the front on the switch contact carrier, which is located in the housing opening; the supply terminal of the switching device is designed as a terminal terminal - preferably as a double-decker clamp - with clamping screw with operation (access) from above, that is, the screwing direction is parallel to the surface in which the housing opening is present

Weiterhin sind an der Steckvorrichtung mindestens ein Paar reziproker Rastelemente ausgebildet und an der Schaltvorrichtung ist mindestens ein Paar Aufnahmeelemente für die Rastelemente der Steckvorrichtung ausgebitdet, mit denen ein rastender, lösbarer Formschluss zwischen den an der Steckvorrichtung angeordneten Rastelementen und den an der Schaltvorrichtung angeordneten Aufnahmeelementen erzielbar ist. Die Aufnahmeelemente an der Schaltvorrichtung sind jedoch nicht extra angefertigt oder hinzugefügt; es werden vorhandene Gestaltungselemente und Gehäuseteile hierzu eingesetzt.Furthermore, at least one pair of reciprocal latching elements are formed on the plug-in device and at least one pair of receiving elements for the latching elements of the plug-in device are grounded with which a latching, releasable positive connection between the locking elements arranged on the plug device and the receiving elements arranged on the switching device can be achieved , However, the receiving elements on the switching device are not specially made or added; existing design elements and housing parts are used for this purpose.

Das besondere Merkmal der Erfindung besteht darin, dass der mindestens eine Zuleitungsenschluss als ein von außen zugänglicher, damit freiliegender Schaltkontaktträger des Schaltapparats der Schaltvorrichtung ausgebildet ist. Das Stecken der Steckvorrichtung kann bei geöffneter Anschluss-Klemme stattfinden.The special feature of the invention is that the at least one supply lead is designed as an externally accessible, thus exposed switching contact carrier of the switching apparatus of the switching device. The plug-in device can be plugged in when the connection terminal is open.

Zusammenwirkende Rastelemente und Aufnahmeelemente bilden jeweils ein antagonistisches oder reziprokes Paar, wobei vorzugsweise eins der Elemente starr und ein anderes Element auch federnd sein kann. Das Verrasten wird somit nicht über die elektrischen Kontakte hergestellt sondern ist eine getrennte mechanische Maßnahme. Der elektrische Kontakt wird somit nicht zusätzlich mechanisch belastet.Co-operating latching elements and receiving elements each form an antagonistic or reciprocal pair, wherein preferably one of the elements may be rigid and another element may also be resilient. The latching is thus not made via the electrical contacts but is a separate mechanical measure. The electrical contact is thus not additionally mechanically stressed.

Mit der Erfindung ist eine schelle Austauschbarkeit von Grundkomponenten einer Schaltvorrichtung, beispielsweise bei Motorstarter-Kombinationen möglich, weil der Verdrahtungsaufwand reduziert ist und Zusatzhalterungen an Trag- oder Adapterschienen, insbesondere als Zugentlastungen für Zuleitungen wegfallen können. Ebenso ist die Betriebnahme schneller machbar, da weniger Handhabungsschritte vorgenommen werden müssen.With the invention, a quick replacement of basic components of a switching device, for example in motor starter combinations possible because the wiring is reduced and additional brackets on support or adapter rails, especially as strain relief for supply lines can be omitted. Likewise, the operation is faster feasible because fewer handling steps must be made.

Das Paar reziproker Rastelemente kann je nach geometrischer Gestaltung der Gehäuse von Steckvorrichtung und/oder Schaltvorrichtung unterschiedlich ausgebildet sein.The pair of reciprocal locking elements may be formed differently depending on the geometric configuration of the housing of the plug device and / or switching device.

Das Paar reziproker Aufnahmeelemente ist erfindungsgemäß so ausgebildet, dass es als eine erste Hinterschneidung an der Zugangsseite und als eine zweite Hinterschneidung an einer senkrecht zur Zugangsseite liegenden Seite der Schaltvorrichtung ausgebildet ist.The pair of reciprocal receiving elements according to the invention is designed such that it is formed as a first undercut on the access side and as a second undercut on a perpendicular to the access side of the switching device.

Die zweite Hinterschneidung ist als Zugangsöffnung für eine Klemmschraube der Doppelstockrahmen-Klemme ausgebildet. Die Zugangsöffnung liegt auf der Oberseite der Schaltvorrichtung. Das Rastelement wird vorzugsweise in der Länge und in der Form (beispielsweise als kreisförmige Noppe) so ausgebildet, dass es gut in die kreisförmige Zugangsöffnung für die Klemmschraube einrastet.The second undercut is formed as an access opening for a clamping screw of the double-decker frame clamp. The access opening lies on top of the switching device. The latching element is preferably formed in length and in shape (for example, as a circular knob) so that it snaps well into the circular access opening for the clamping screw.

Die Lage von Hinterschneidungen ist in den genannten Ausführungsbeispielen als Zuordnung zu Gehäuseseiten der Schaltvorrichtung formuliert. Es sollen zusätzlich auch Lagen von Hinterschneidungen vorgesehen sein können, die an Gehäusekanten ausgebildet sind. Für den Fachmann ist unmittelbar ersichtlich, dass es weniger auf die Lage der Hinterschneidungen ankommt, als auf die funktionelle Wirkung. Die Reziprozität der Rast- und auch Aufnahmeelemente ist durch eine in einer Linie liegende Wirkungsrichtung bestimmt. Dabei kann die Wirkungslinie waagerecht, senkrecht oder auch schräg verlaufen. Es kommt allein auf die klemmende Wirkung oder den rastenden Formschluss an.The position of undercuts is formulated in the aforementioned embodiments as an assignment to housing sides of the switching device. It should also be provided layers of undercuts, which are formed on the edges of the housing. It is obvious to the person skilled in the art that the position of the undercuts matters less than the functional effect. The reciprocity of the locking and receiving elements is determined by a lying in a line direction of action. In this case, the line of action can be horizontal, vertical or oblique. It depends solely on the clamping effect or the latching form fit.

Im Vorhergehenden sind Ausführungsformen angesprochen, bei denen die Aufnahmeelemente an der Schaltvorrichtung und die Rastelemente an der Steckvorrichtung ausgebildet sind. Es Ist klar, dass eine Vertauschung (Aufnahmeelemente an der Steckvorrichtung, Rastelemente an der Schaltvorrichtung) zu äquivalenten Ausführungsformen der Erfindung gehören,In the foregoing embodiments are addressed, in which the receiving elements are formed on the switching device and the locking elements on the plug-in device. It is clear that a permutation (receiving elements on the plug-in device, latching elements on the switching device) belong to equivalent embodiments of the invention,

Rastelemente und/oder Aufnahmeelemente können federnd ausgebildet sein. Die federnde Eigenschaft soll eine größere Weglänge ermöglichen, als sie nur aus der elastischen Eigenschaft des Werkstoffs gegeben werden würde. Der längere Weg für den Eingriff der federnden Rast- und/oder Aufnahmeelemente erlaubt, dass solche Elemente in Hinterschneidungen tiefer eindringen können.Locking elements and / or receiving elements may be resilient. The resilient property should allow a longer path length, as it would be given only by the elastic property of the material. The longer path for the engagement of the resilient latching and / or receiving elements allows such elements can penetrate deeper in undercuts.

Ein federndes Rastelement kann eine rückwärtige Verlängerung (in Art eines Hebelarms) aufweisen. Mit einem so ausgebildeten - und in den Figuren noch besser verdeutlichen Hebelarm ist das federnde Rastelement leicht und ohne Werkzeug aus einer Verrastung lösbar.A resilient locking element may have a rearward extension (in the manner of a lever arm). With such a trained - and in the figures even better clarified lever arm, the resilient locking element is easily and without tools from a catch solvable.

Ein federndes Rastelement kann einstückig mit dem Gehäuse einer Steckvorrichtung oder einer Schaltvorrichtung ausgebildet sein. Für den Fachmann ist klar, dass das Gehäuse aus isolierstoff bestehen soll. Bei der Herstellung des Gehäuses kommt die Wirtschaftlichkeit der Herstelltechnik und der Ausbildung des Spritzgusswerkzeugs ins Spiel; hierbei können Fertigungsoptimierungen vorgenommen werden, wobei auch solche Ausbildungen wie die vorerwähnte Einstückigkeit von Rastelement und Gehäuse in Frage kommen. Weitere Formbildungen von Gehäusen von Steckvorrichtung können auch darin bestehen, dass diese aus zwei identischen Gehäusehätften aufgebaut sind.A resilient latching element may be formed integrally with the housing of a plug-in device or a switching device. It is clear to the person skilled in the art that the housing should consist of insulating material. In the manufacture of the housing, the economy of the manufacturing technology and the design of the injection molding tool comes into play; In this case, manufacturing optimizations can be made, with such training as the aforementioned one-piece of locking element and housing come into question. Further formations of housings of plug-in device may also consist in that they are constructed from two identical Gehäusehätften.

Die Steckvorrichtung kann mit mehr als einem Zuleitungsanschluss und entsprechen vielen (beispielsweise drei) Steckkontakten ausgebildet sein. Es liegen dann mehrphasige (beispielsweise dreiphasige) Steckvorrichtung vor. Bei mehrphasigen Steckvorrichtungen liegen Zuleitungsanschlüsse und Steckkontakte nebeneinander. Hiermit ist es auch möglich, Leitungen von einem Zuleitungsanschluss zu einem anderen Zuleitungsanschluss an der Schaltvorrihtung durchzuschleifen. Mehrphasigkeit der Steckkontakte kann man erreichen, indem mehrere einphasige Steckkontakte nebeneinander angeordnet werden oder indem man eine einzige mehrphasige Steckvorrichtung (in einem Gehäuse) als Block ausbildet. Zur Aneinanderreihung von einphasigen Steckvorrichtungen können an den Steckkontaktgehäusen Verzahnungen (beispielsweise als Nut-und-Feder- oder als Schwalbenschwanz-Verzahnung) vorgesehen sein.The plug-in device can be designed with more than one supply connection and correspond to many (for example three) plug contacts. There are then multiphase (for example, three-phase) plug-in device. In multi-phase plug devices are feeder connections and plug contacts side by side. This also makes it possible to loop through cables from one supply connection to another supply connection to the switching device. Polyphase of the plug contacts can be achieved by juxtaposing several single-phase plug-in contacts or by forming a single multi-phase plug-in device (in a housing) as a block. For juxtaposition of single-phase plug-in devices toothings (for example, as a tongue and groove or dovetail teeth) can be provided on the plug contact housings.

Der Steckkontakt kann vorzugsweise als Tulpenkontakt ausgebildet sein. Hiermit lässt sich am besten eine schwimmende Kontaktgabe - ohne mechanische Verrastung - vermitteln. Die Aufnahmeklemme kann als Push-In-Klemme ausgebildet sein. Die erfindungsgemäße Steckvorrichtung dient insbesondere auch als Zugentlastung für Zuleitungen (flexible Adem).The plug contact may preferably be designed as a tulip contact. This is the best way to convey a floating contact - without mechanical locking. The receiving clamp can be designed as a push-in terminal. The plug-in device according to the invention also serves in particular as a strain relief for supply lines (flexible adem).

Bei dem Gegenstand der Erfindung können beispielsweise Anschlussleitungen bis 4 mm2 an die Schaltvorrichtung werkzeuglos gesteckt und gerastet werden.In the subject of the invention, for example, connection cables can be inserted to 4 mm 2 to the switching device without tools and locked.

Die Erfindung wird in mehreren Figuren dargestellt. wobei diese im Einzelnen zeigen:

  • Fig. 1 eine schematische Zuordnung von Steckvonichtung und Schaltvorrichtung,
  • Fig. 2 eine Ausgestaltung von Steckvorrichtung und Schaltvorrichtung (auch im Teilschnitt),
  • Fig. 3 eine dreiphasig ausgebildete Steckvorrichtung,
  • Fig. 4 eine Steckvorrichtung auf eine Schaltvorrichtung (Schütz) aufgesteckt.
The invention is illustrated in several figures. these show in detail:
  • Fig. 1 a schematic assignment of plug-in device and switching device,
  • Fig. 2 an embodiment of plug-in device and switching device (also in partial section),
  • Fig. 3 a three-phase plug-in device,
  • Fig. 4 a plug-in device attached to a switching device (contactor).

Gemäß Fig. 1 sind an der Schaltvorrichtung 50 (schematisch) fünf Flächen (A1, A2', A2", A3', A3") dargestellt, wobei die Fläche A1 die sogenannte Zugangsfläche ist, in der der Schaltkontaktträger 52 in einer Eintrittsöffnung 54 ausgebildet istAccording to Fig. 1 5 (schematically) five surfaces (A1, A2 ', A2 ", A3', A3") are shown on the switching device 50, wherein the surface A1 is the so-called access surface, in which the switching contact carrier 52 is formed in an inlet opening 54

Figur 2 zeigt rechts einen Schnitt durch die Schaltvorrichtung 50, welche einen - wie üblich, jedoch in der Zeichnung nicht dargestellten - Schaltapparat umfasst. Bestandteil des Schaltapparats der Schaltvorrichtung 50 ist der als Stromschiene ausgebildete Schaltkontaktträger 52. Der Schaltkontaktträger 52 ist auf der Zugangsfläche A1 zugänglich. Bei dem Ausführungsbeispiel ist der Schaltkontaktträger 52 als Mittenkontakt einer Doppelstockrahmen-Klemme ausgebildet. Solange die Klemmschraube 58 nicht eingeschraubt ist, ist das in die Öffnung 54 nach außen ragende Ende des Schaltkontaktträgers frei zugänglich. Als Klemme kann auch eine Einfachklemme eingesetzt werden, bei der durch die Klemmschraube eine Druckplatte in Richtung auf den Schaltkontaktträger 52 bewegbar ist, womit eine eingeführte Litze klemmbar wäre. FIG. 2 shows on the right a section through the switching device 50, which comprises a - as usual, but not shown in the drawing - switching apparatus. Part of the switching apparatus of the switching device 50 is formed as a busbar switch contact carrier 52. The switch contact carrier 52 is accessible on the access surface A1. In the embodiment, the switch contact carrier 52 is formed as a center contact of a double-decker clamp. As long as the clamping screw 58 is not screwed, the opening 54 in the outwardly projecting end of the switch contact carrier is freely accessible. As a terminal, a single terminal can be used in which by the clamping screw, a pressure plate in the direction of the switch contact carrier 52 is movable, whereby an inserted strand would be clamped.

Die Figuren 1 und 2 zeigen die räumliche Zuordnung der Steckvorrichtung 10 zu der Schaltvorrichtung 50, wobei an der Schaltvorrichtung schematisch verschiedene Aufnahmeelemente AE eingezeichnet sind. Es ist klar, dass für das Verbinden der Steckvorrichtung mit der Schaltvorrichtung wesentlich ist, dass nur ein Paar von reziproken Aufnahmeelementen an der Schaltvorrichtung vorhanden zu sein brauchen. Die Darstellung in Fig. 1 soll die Vielfalt der Möglichkeiten andeuten.The FIGS. 1 and 2 show the spatial assignment of the plug-in device 10 to the switching device 50, wherein schematically different recording elements AE are shown on the switching device. It is clear that it is essential for the connection of the plug-in device to the switching device that only a pair of reciprocal receiving elements need to be present on the switching device. The representation in Fig. 1 should indicate the variety of possibilities.

Die jeweiligen Paare von reziproken Aufnahmeelementen sind mit dem Bezugszeichen AE gekennzeichnet. Wesentlich an der Funktionalität von Aufnahme- und Rastelemente ist, dass ihre Reziprozität durch eine in einer Linie liegende Wirkungsrichtung bestimmt ist. Dabei kann die Wirkungslinie waagerecht, senkrecht oder auch schräg verlaufen. Es kommt allein auf die klemmende Wirkung oder den rastenden Formschluss an. Die klemmende Wirkung, bzw. der rastende Formschluss wird mit Pfeilen mit den Bezugszeichen Rx angedeutet. Pfeile R1 und R2, R3 und R4 bilden jeweils ein reziprokes Paar. Die Reziprozität ist auch durch ein sogenanntes Rast-Maß bestimmt, welches mit dem Bezugszeichen RM bei der Schaltvorrichtung 50 und der Steckvorrichtung 10 angedeutet ist. Ein weiteres, in Fig. 1 dargestelltes Maß ist die Tiefe ST, mit der die Steckvorrichtung in die Schaltvorrichtung (in die Öffnung 54) eingeführt werden kann.The respective pairs of reciprocal receiving elements are designated by the reference character AE. Essential to the functionality of receiving and locking elements is that their reciprocity is determined by a direction of action lying in a line. In this case, the line of action can be horizontal, vertical or oblique. It depends solely on the clamping effect or the latching form fit. The clamping effect, or the latching positive locking is indicated by arrows with the reference symbol Rx. Arrows R1 and R2, R3 and R4 each form a reciprocal pair. The reciprocity is also determined by a so-called latching measure, which is indicated by the reference numeral RM in the switching device 50 and the plug-in device 10. Another, in Fig. 1 shown measure is the depth ST, with which the plug-in device in the switching device (in the opening 54) can be inserted.

Wie in der Figur 1 angedeutet können Aufnahmeelemente (AE) Hinterschneidungen, Kanten. Nocken, Vertiefungen oder Bohrungen sein. Beispielsweise ist die obere kreisrunde Bohrung AEO ein bevorzugtes Aufnahmeelement, welches in den weiteren Figuren noch näher dargestellt ist Dort ist diese als Zugangsbohrung AE0 für eine Klemmschraube der Doppelstockrahmen-Klemme 56 zu verstehen.Like in the FIG. 1 Indicated may be recording elements (AE) undercuts, edges. Cams, wells or holes. For example, the upper circular bore AEO is a preferred receiving element, which is shown in more detail in the other figures. There, this is to be understood as an access hole AE0 for a clamping screw of the double-decker frame clamp 56.

In der linken Hälfte der Fig. 1 ist eine (einphasige) Steckvorrichtung 10 dargesteltt Sie hat einen Tulpenkontakt ausgebildeten Steckkontakt 12, der dem Schaltkontaktträger 52 in der Zugangsseite A1 der Schaltvorrichtung 50 zugeordnet ist. Dem Steckkontakt 12 liegen zwei Einführöffnungen 42 für Aderenden gegenüber. In die Einführöffnungen können Litzen eingeführt werden, wobei starre Litzen ohne und flexible Litzen mit Aderendhülsen versehen sein können. Im Innern des Gehäuses wird vorzugsweise mindestens eine Push-In-Klemme (siehe Fig. 2) angeordnet Zur Entriegelung einer gesteckten Litze ist je eine Einführöffnung 60 für ein Entriegelungswerkzeug vorhanden. Der Aufbau der Steckvorrichtung ist selbstverständlich bezüglich Luft- und Kriechstrecken der jeweiligen Spannungsebene angepasst.In the left half of the Fig. 1 is a (single-phase) plug-in device 10 dargesteltt It has a tulip contact formed plug contact 12, which is assigned to the switch contact carrier 52 in the access side A1 of the switching device 50. The plug contact 12 are opposite two insertion openings 42 for wire ends. Strands can be introduced into the insertion openings, wherein rigid strands can be provided with ferrules without and flexible strands. In the interior of the housing is preferably at least one push-in terminal (see Fig. 2 For unlocking a plugged strand, an insertion opening 60 is provided for an unlocking tool. The structure of the plug-in device is of course adapted to creepage and clearance distances of the respective voltage level.

Das reziproke Paar Rastelemente an der Steckvorrichtung wird von der kreisrunden Nocke 16 und der Rastnase 18 gebildet. An der Rastnase ist zusätzlich - jedoch nicht notwendig - noch ein Halbrund 19 ausgebildet Die Rastwirkung wird durch das Paar der Pfeile RS3 und RF4 dargestellt.The reciprocal pair of latching elements on the plug-in device is formed by the circular cam 16 and the latching lug 18. At the locking lug is additionally - but not necessary - still a half-round 19 is formed The locking action is represented by the pair of arrows RS3 and RF4.

Das Rastelement 14 ist ein federnder Doppelarm, welcher durch den räumlichen Freischnitt im Gehäuse bei Bezugszeichen 17 relativ weit federnd drehbar ist Die Länge (Abstand zur Schaltvorrichtung) und ihre Form (beispielsweise als kreisförmige Noppe) sind so ausgebildet dass ein optimales Einrasten in die kreisförmige Zugangsöffnung stattfinden kann.The locking element 14 is a resilient double arm, which is relatively far resiliently rotatable by the spatial cutout in the housing at reference 17 The length (distance to Switching device) and its shape (for example, as a circular knob) are formed so that an optimal engagement can take place in the circular access opening.

Mit dem Hebelarm 15 des Rastelements 14 wird die Entrieglung durch manuelle Betätigung vorgenommen. Der Winkelweg, den das Rastelement 14 vornehmen kann. ist mit dem Bezugszeichen F dargestellt. In der Figur ist sichtbar, dass der Fuß des Rastelements 14 formschlüssig in das Gehäuse eingebracht ist. Eine Alternative könnte die einstücklge Ausbildung zusammen mit dem Gehäuse oder einem Gehäuseteil sein.With the lever arm 15 of the locking element 14, the Entrieglung is made by manual operation. The angular travel, which can make the locking element 14. is represented by the reference symbol F. In the figure it is visible that the foot of the locking element 14 is positively inserted into the housing. An alternative could be the einstücklge training together with the housing or a housing part.

Die Fig. 2 zeigt eine konkrete Ausgestaltung von Steckvorrichtung und einer als Schütz dargestellten Schaltvorrichtung. Beide Vorrichtungen sind im Teilschnitt gezeigt, um den inneren Aufbau sichtbar zu machen. Die schon aus Fig. 1 bekannten Einzelheiten werden nicht wiederholt. Wesentlich an Fig. 2 ist die Darstellung der elektrischen Elemente In Innern der Steckvorrichtung, nämlich zwei Push-In-Klemmen 40, ein Tulpenkontakt 12 und die leitende Verbindung zwischen beiden. An dem Schütz 50 ist durch den zeichnerischen Schnitt besonders der Schaltkontaktträger 52, die Einführungsöffnung 54, die Klemmschraube 58 für die DoppelstockrahmenKlemme 56 und die Zugangsöffnung AEO für die Klemmschraube 58 erkennbar. Der zum Schaltkontaktträger gehörende Schattapparat ist nicht dargestellt Die Zugangsöffnung AE0 fungiert hier als eine erste Hinterschneidung (siehe Pfeil R4), die reziproke, andere Hinterschneidung ist eine im unteren Bereich der Zugangsseite A1 ausgebildete Kante (siehe Pfeil R3).The Fig. 2 shows a specific embodiment of plug-in device and a switching device shown as a contactor. Both devices are shown in partial section to make the internal structure visible. They are already out Fig. 1 known details are not repeated. Essential to Fig. 2 is the representation of the electrical elements inside the plug-in device, namely two push-in terminals 40, a tulip contact 12 and the conductive connection between the two. On the contactor 50 is the drawing section particularly the switch contact carrier 52, the insertion opening 54, the clamping screw 58 for the double-decker frame clamp 56 and the access opening AEO for the clamping screw 58 recognizable. The access door AE0 functions here as a first undercut (see arrow R4), the reciprocal, other undercut is an edge formed in the lower area of the access side A1 (see arrow R3).

Die Fig. 3 zeigt eine dreiphasig ausgebildete Steckvorrichtung 10a. Wie schon einleitend dargestellt, kann eine solche Ausbildung in einem einzigen Gehäuse - quasi als Block - ausgebildet sein, oder es können mehrere einphasige Steckvorrichtungen 10 nebeneinander angeordnet sein. Zur Erhöhung der Stabilität bei einer Reihung können an den Steckkontaktgehäusen Verzahnungen vorgesehen sein. Angedeutet ist dies in Fig. 3 durch eine Schwalbenschwanz-Verzahnung 48 zwischen den Einzel-Gehäusen.The Fig. 3 shows a three-phase plug-in device 10a. As already explained in the introduction, such a design can be embodied in a single housing-virtually as a block-or a plurality of single-phase plug-in devices 10 can be arranged next to each other. To increase the stability in a series gears can be provided on the plug contact housings. This is indicated in Fig. 3 by a dovetail toothing 48 between the individual housings.

Die Fig. 4 zeigt ein Schütz 50 mit einer gesteckten Steckvorrichtung 10. Beispielswelse würde in dieser Darstellung die Steckvorrichtung als Einspeise- oder Abgangsstecker einzusetzen sein. In dieser Darstellung wird besonders auch ein weiterer Vorteil der Erfindung deutlich, dass nämlich das Rastelement 16 den Zugang zur Klemmschraube 58 verschließt, so dass ein unabsichtliches Verdrehen der Klemmschraube verhinderbar wird.The Fig. 4 shows a contactor 50 with an inserted plug device 10. Beispielswelse would be used in this illustration, the plug-in device as a feeder or outgoing connector. In this illustration, a further advantage of the invention is particularly clear, namely that the locking element 16 closes the access to the clamping screw 58, so that an unintentional rotation of the clamping screw can be prevented.

Man erkennt auf der Oberseite des Schütz noch Öffnungen 55 für weitere Zugänge. Hier könnte in der Kombistecktechnik eine Reversierbrücke für eine Motorsteuerung einsteckbar sein. Zur beachten ist, dass die Länge des Rastelements 14 noch so gewählt ist, dass die Öffnungen 55 nicht abgedeckt werden.It can be seen on the top of the contactor still openings 55 for further access. Here, a reversing bridge for a motor control could be inserted in the combination plug-in technology. to Note that the length of the locking element 14 is still chosen so that the openings 55 are not covered.
