Dadurch, dass erfindungsgemäß die Abdeckplatte an den Stirnseiten der Seitenplatten verschieblich geführt anliegt, bedeckt sie den Klemmenrahmen von vorne, auch die Stirnseiten sind zumindest teilweise bedeckt, und es ist eine gute Führung des Klemmenabdeckteils auch bei einem breiten Klemmenrahmen mit großem Querschnitt für die Einführung von Anschlussleitern mit einem größeren Durchmesser von bis zu 50 mm2 gegeben. Die erfindungsgemäß an der Abdeckplatte lateral nach außen zu den Gehäusebreitseiten hin federnd ausgebildeten Haltearme bewirken eine vorteilhafte federnde Abstützung des Klemmenabdeckteils an der Gehäusewand. Dadurch und auch im Zusammenwirken mit den medial zu den Haltearmen hin orientierten Anschlagsmitteln wird die Klemme in der offenen Stellung gehalten, und dadurch kann verhindert werden, dass sich die Klemmschraube beispielsweise durch Erschütterungen selbst zudreht.Due to the fact that according to the invention the cover plate is slidably guided on the end faces of the side plates, it covers the terminal frame from the front, and the end faces are at least partially covered, and it is a good leadership of the terminal cover even with a wide terminal frame with a large cross-section for the introduction of Connecting conductors with a larger diameter of up to 50 mm 2 given.

Gemäß einer vorteilhaften Ausführungsform der Erfindung sind die Haltearme an ihren freien Enden mit lateral nach außen zu den Gehäusebreitseiten hin von den Längskanten abstehenden nasenartigen Vorsprüngen ausgebildet. Die nasenartigen Vorsprünge eignen sich gut als Rastmittel, um die Abdeckplatte mit den Anschlagsmitteln zu verrasten, in der Position, wenn die Klemmschraube nach oben gedreht ist, um so ein selbständiges herabdrehen der Klemmschraube, etwa durch Erschütterungen, zu verhindern.According to an advantageous embodiment of the invention, the retaining arms are formed at their free ends with laterally outwardly to the housing broad sides projecting from the longitudinal edges nose-like projections.

Der Schlitz kann auch als eine Tasche angesehen werden. In diese Tasche fährt die Abdeckplatte hinein, wenn die Klemmschraube herausgedreht wird, und wenn dann in der oberen Position der Klemmschraube die Abdeckplatte die obere Gewindeplatte des Klemmenrahmens überragt.

Gemäß einer vorteilhaften Ausführungsform der Erfindung ist mit dem Koppelfortsatz ein Druckstück zum Andrücken eines Anschlussleiters zwischen der Klemmschraube und der Klemmplatte gekoppelt, wobei der Haltearm zwischen dem Druckstück und dem Absatz am Klemmende der Klemmschraube unverlierbar an dem Koppelfortsatz gehalten ist.According to an advantageous embodiment of the invention, a pressure piece for pressing a connecting conductor between the clamping screw and the clamping plate is coupled to the coupling extension, wherein the holding arm between the pressure piece and the shoulder at the clamping end of the clamping screw is held captive on the coupling extension.

Aufgrund der oben genannten vorteilhaften Ausgestaltungen wird eine sehr vorteilhafte Montagereihenfolge eröffnet. Zuerst wird dabei die Klemmschraube in das Gewinde in der oberen Gewindeplatte eingeschraubt. Als nächstes wird der Haltearm auf den Koppelfortsatz der Klemmschraube aufgeschoben. Der Haltearm kann dazu eine Öffnung mit einer Öffnungskontur haben, die in etwa der Außenkontur des Koppelfortsatzes entspricht. Danach wird das Druckstück über den unteren Teil des Koppelfortsatzes gesetzt. Der untere Teil des Koppelfortsatzes kann dazu einen anderen Durchmesser als der Teil des Koppelfortsatzes, an dem der Haltearm steckt, haben. Insbesondere kann der untere Teil des Koppelfortsatzes einen kleineren Durchmesser haben. Das Druckstück wird anschließend mit dem unteren Teil des Koppelfortsatzes vernietet oder verstemmt. Das Druckstück und der Haltearm und damit die Abdeckplatte sind nun mit der Klemmschraube unverlierbar verbunden. Weil die Klemmschraube zuvor in das Gewinde in der oberen Gewindeplatte eingeschraubt worden war und sich damit das Klemmende der Klemmschraube zwischen der oberen Gewindeplatte und der unteren Klemmplatte befindet, ist damit auch die Klemmschraube unverlierbar mit dem Klemmrahmen verbunden.Due to the above advantageous embodiments, a very advantageous assembly order is opened. First, the clamping screw is screwed into the thread in the upper threaded plate. Next, the retaining arm is pushed onto the coupling extension of the clamping screw. The holding arm may have an opening with an opening contour, which corresponds approximately to the outer contour of the coupling extension. Thereafter, the pressure piece is placed over the lower part of the coupling extension. The lower part of the coupling extension can for this purpose have a different diameter than the part of the coupling extension on which the holding arm is inserted. In particular, the lower part of the coupling extension may have a smaller diameter. The pressure piece is then riveted or caulked to the lower part of the coupling extension. The pressure piece and the retaining arm and thus the cover plate are now connected captively with the clamping screw. Because the clamping screw was previously screwed into the thread in the upper threaded plate and thus the clamping end of the clamping screw between the upper threaded plate and the lower clamping plate is, so that the clamping screw is captively connected to the clamping frame.

Gemäß einer weiteren vorteilhaften Ausführungsform ist der Haltearm zwischen dem Druckstück und dem Absatz am Klemmende der Klemmschraube aufgeklipst oder aufgesteckt und damit nicht unverlierbar gehalten. Der Haltearm kann dazu an seinem freien Ende eine gabelartige Aufweitung haben, mit den beiden Gabelzinken wird er dann an das Klemmende der Klemmschraube aufgesteckt. Die Gabelzinken haben in vorteilhafter Weise federelastische Eigenschaften, wodurch der Haltearm an dem Klemmfortsatz federnd verrasten kann.According to a further advantageous embodiment of the support arm is clipped or plugged between the pressure piece and the paragraph at the terminal end of the clamping screw and thus not held captive. The support arm can do this at its free end have a fork-like expansion, with the two forks it is then attached to the terminal end of the clamping screw. The forks have in an advantageous manner spring elastic properties, whereby the support arm can latch on the clamping extension resiliently.

Mit dieser vorteilhaften Ausgestaltung wird eine andere vorteilhafte Montagereihenfolge eröffnet. Zuerst wird dabei auch hier die Klemmschraube in das Gewinde in der oberen Gewindeplatte eingeschraubt. Als nächstes wird hier nun das Druckstück über den unteren Teil des Koppelfortsatzes gesetzt und anschließend mit dem unteren Teil des Koppelfortsatzes vernietet oder verstemmt. So ist das Druckstück mit der Klemmschraube unverlierbar verbunden. Weil die Klemmschraube zuvor in das Gewinde in der oberen Gewindeplatte eingeschraubt worden war und sich damit das Klemmende der Klemmschraube zwischen der oberen Gewindeplatte und der unteren Klemmplatte befindet, ist damit auch die Klemmschraube unverlierbar mit dem Klemmrahmen verbunden. Nun wird der Haltearm auf den Koppelfortsatz der Klemmschraube aufgeschoben, in den Bereich des oberen Teils des Koppelfortsatzes, zwischen das Druckstück und den Absatz am Klemmende der Klemmschraube, und dort federnd verrastet, wie oben beschrieben.With this advantageous embodiment, another advantageous assembly order is opened. First, the clamping screw is screwed into the thread in the upper threaded plate. Next, the pressure piece is now placed over the lower part of the coupling extension and then riveted or caulked to the lower part of the coupling extension. Thus, the pressure piece is captively connected to the clamping screw. Because the clamping screw was previously screwed into the thread in the upper threaded plate and thus the clamping end of the clamping screw between the upper threaded plate and the lower clamping plate is, so that the clamping screw is captively connected to the clamping frame. Now, the support arm is pushed onto the coupling extension of the clamping screw, in the region of the upper part of the coupling extension, between the pressure piece and the paragraph at the terminal end of the clamping screw, and there resiliently locked, as described above.

Beim Öffnen der Klemmschraube, also bei Herausdrehen, kann die Klemmschraube in einen Freilauf gelangen, was bedeutet, dass das Gewinde der Klemmschraube mit dem Gewinde in der oberen Gewindeplatte im Zustand des Freilaufes nicht mehr in Eingriff miteinander stehen. Der Freilauf verhindert in vorteilhafter Weise ein Verklemmen des Abdeckteils und des Druckstücks mit dem Klemmenrahmen.When opening the clamping screw, so when unscrewing, the clamping screw can get into a freewheel, which means that the thread of the clamping screw with the thread in the upper threaded plate in the state of the freewheel are no longer engaged. The freewheel advantageously prevents jamming of the cover and the pressure piece with the terminal frame.

Gemäß einer vorteilhaften Ausführungsform der Erfindung ist eine an der Frontseite gelegene Zugangsöffnung zu dem Betätigungsende der Klemmschraube mit einer die Zugangsöffnung kranzförmig umgebenden, erhabenen Wulst ausgebildet. Die erfindungsgemäß vorgesehene Wulst erhöht die Fingersicherheit, also den Berührschutz vor versehentlichem Berühren der möglicherweise stromführenden Klemmschraube mit dem Finger.According to an advantageous embodiment of the invention, an access opening located on the front side to the actuating end of the clamping screw is formed with a raised bead which surrounds the access opening in a circle-like manner. The inventively provided bead increases finger safety, so the contact protection against accidental touching the possibly current-carrying clamping screw with the finger.

Die Figur 1 zeigt eine Ansicht auf die Schmalseite 4 eines erfindungsgemäßen Installationsschaltgerätes 1. Das Installationsschaltgerät 1 ist hier ein einpoliger Leitungsschutzschalter, es könnte aber auch ein mehrpoliger Leitungsschutzschalter oder ein Fehlerstromschutzschalter oder dergleichen sein. Der Leitungsschutzschalter 1 hat ein Gehäuse 2 aus einem Isolierstoff, oft ist das Gehäuse aus einem Thermoplast oder einem Duroplast und im Spritzgussverfahren hergestellt. Das Gehäuse 2 hat zwei sich einander gegenüber liegende Breitseiten 3, zwei Schmalseiten 4, von denen hier nur eine zu sehen ist, eine Frontseite 5 und eine der Frontseite 5 gegenüber liegende Befestigungsseite 6.The FIG. 1 shows a view of the narrow side 4 of a service switching device according to the invention 1. The service switching device 1 is here a single-pole circuit breaker, but it could also be a multi-pole circuit breaker or a residual current circuit breaker or the like. The circuit breaker 1 has a housing 2 made of an insulating material, often the housing is made of a thermoplastic or a thermosetting plastic and injection-molded. The housing 2 has two mutually opposite broad sides 3, two narrow sides 4, of which only one can be seen here, a front side 5 and a front side 5 opposite mounting side. 6

In dem Bereich einer Schmalseite 4 und zwischen den beiden Breitseiten 3 befindet sich in einem Klemmenaufnahmeraum 7 und ist darin gehalten eine Anschlussklemme 8. Die Anschlussklemme 8 umfasst einen Klemmenrahmen 10. Dieser umgibt einen Klemmraum 9. Der Klemmenrahmen 10 hat eine obere, ein Innengewinde tragende, Gewindeplatte 11, eine untere Klemmplatte 12 und zwei die Gewindeplatte 11 mit der Klemmplatte 12 verbindende, jeweils eine Stirnseite 13,13' und Breitseiten 14, 14' aufweisende, Seitenplatten 15, 15'.In the region of a narrow side 4 and between the two broad sides 3 is located in a terminal receiving space 7 and is held therein a terminal 8. The terminal 8 comprises a terminal frame 10. This surrounds a terminal space 9. The terminal frame 10 has an upper, an internal thread bearing , Threaded plate 11, a lower clamping plate 12 and two the threaded plate 11 with the clamping plate 12 connecting, one end face 13,13 'and broad sides 14, 14' having, side plates 15, 15 '.

In dem Innengewinde ist eine Klemmschraube 16 eingeschraubt. Hier ist die Klemmschraube eine kopflose Schraube. Sie hat einen Gewindeschaft 35, ein Klemmende 17 und ein Betätigungsende 18. An dem Betätigungsende 18 befindet sich eine Eingriffsöffnung für ein Betätigungswerkzeug, hier ein gekreuzter Schlitz für einen Kreuzschlitzschraubendreher. Die Klemmschraube kann nach oben aus dem Klemmraum 9 herausgeschraubt werden. Sie befindet sich dann in einer ersten, geöffneten Position, in der das Klemmende 17 von der Klemmplatte 12 entfernt ist. Die Klemmschraube 16 kann auch nach unten in den Klemmraum 9 hineingeschraubt werden, bis zu einer zweiten, geschlossenen Position, in der das Klemmende 17 an der Klemmplatte 12 anliegt.In the internal thread a clamping screw 16 is screwed. Here the clamping screw is a headless screw. It has a threaded shaft 35, a clamping end 17 and an actuating end 18. At the actuating end 18 is an engagement opening for an operating tool, here a crossed slot for a Phillips screwdriver. The clamping screw can be unscrewed upwards out of the clamping space 9. It is then in a first, open position, in which the clamping end 17 is removed from the clamping plate 12. The clamping screw 16 can also be screwed down into the clamping space 9, up to a second, closed position in which the clamping end 17 rests against the clamping plate 12.

Wie in der Figur 3 zu erkennen ist, hat die Klemmschraube 16 an ihrem Klemmende 17 ein Druckstück 36, das auch als Druckplatte 36 bezeichnet werden kann. Mit dem Druckstück klemmt die Klemmschraube ein abisoliertes Endstück eines in den Klemmraum 9 eingeführten Anschlussleiters fest.Like in the FIG. 3 can be seen, the clamping screw 16 at its terminal end 17 a pressure piece 36, which may also be referred to as a pressure plate 36. With the pressure piece, the clamping screw clamps a stripped end piece of a lead introduced into the terminal compartment 9.

In der Figur 4 ist die Anschlussklemme 8 in teilweise geöffneter Position zu sehen. Man sieht ein Leiterstück 39, das in den Klemmraum 9 ragt und diesen in einen oberen und einen unteren Abschnitt unterteilt. Der obere Abschnitt erstreckt sich zwischen dem Leiterstück 39 und der Gewindeplatte 11, der untere Abschnitt erstreckt sich zwischen dem Leiterstück 39 und der Klemmplatte 12. Das Leiterstück 39 führt ins Innere des Installationsschaltgerätes 1, es ist Teil des Strompfades durch das Installationsschaltgerät 1, an den mittels der Anschlussklemme 8 von außen ein Anschlussleiter angeschlossen werden kann. Der obere Abschnitt des Klemmraums 9 wird bei üblichen Installationsschaltgeräten als Leiteranschlussraum bezeichnet, er dient zum Einführen und Festklemmen von Anschlussleitern. Der untere Abschnitt des Klemmraums 9 wird bei üblichen Installationsschaltgeräten auch als Querverdrahtungsraum bezeichnet, er dient zum Anschluss einer Querverdrahtung, also einer Stromschiene, die mehrere nebeneinander angereihte Installationsschaltgeräte 1 elektrisch miteinander verbindet. Entsprechend hat auch das Isolierstoffgehäuse 2 an der Schmalseite in der Nähe der Anschlussklemme 8 zwei Öffnungen, eine Leiteröffnung 29, hier im Folgenden auch als Gehäusezugangsöffnung bezeichnet, und eine Querverdrahtungsöffnung. Beide sind üblicherweise durch einen Steg 41 voneinander getrennt.In the FIG. 4 the connection terminal 8 can be seen in partially open position. It can be seen a conductor piece 39 which projects into the terminal space 9 and divides this into an upper and a lower portion. The upper portion extends between the conductor piece 39 and the threaded plate 11, the lower portion extends between the conductor piece 39 and the clamping plate 12. The conductor piece 39 leads into the interior of the service switching device 1, it is part of the current path through the service switching device 1, to the by means of the terminal 8 from the outside, a connection conductor can be connected. The upper portion of the terminal space 9 is referred to in conventional service switching devices as a conductor terminal compartment, it is used for insertion and clamping of connecting conductors. The lower portion of the terminal space 9 is referred to in conventional service switching devices as a cross-wiring space, it is used to connect a cross-wiring, ie a busbar that connects a plurality of juxtaposed adjacent installation switching devices 1 electrically. Correspondingly, the insulating housing 2 on the narrow side in the vicinity of the terminal 8 has two openings, a conductor opening 29, hereinafter also referred to as housing access opening, and a cross-wiring opening. Both are usually separated by a web 41 from each other.

Es besteht die Anforderung, für einen Fehlsteckschutz, auch Hintersteckschutz genannt, zu sorgen. Das bedeutet, dass bei geschlossener Anschlussklemme 8, wenn also die Klemmschraube nach unten gedreht ist, auf dem Leiterstück 39 sich abstützt und bei weiterem Drehen dann den Klemmenrahmen 10 nach oben in Richtung auf die Frontseite 5 hin zieht, so dass die Klemmplatte am oberen, der Frontseite 5 zuweisenden Kante der Querverdrahtungsöffnung zu liegen kommt, Maßnahmen vorgesehen sind, damit kein Anschlussleiter irrtümlich in die nun offene Querverdrahtungsöffnung eingeführt werden kann oder auch nicht in die Leitereinführöffnung eingeführt und sich dann an der Klemmschraube abstützt.There is a requirement to provide for a false plug protection, also called Hintersteckschutz. This means that when the terminal 8 is closed, that is, when the clamping screw is turned down, is supported on the conductor piece 39 and further rotation then the terminal frame 10 pulls up towards the front 5, so that the clamping plate at the top, the front 5 facing edge of the cross-wiring opening comes to lie, measures are provided so that no connection conductor can be erroneously inserted into the now open cross-wiring opening or not inserted into the Leitereinführöffnung and then supported on the clamping screw.

Dazu ist bekanntermaßen an der Klemmplatte 12 eine nachunten abgebogene und damit zu der Befestigungsseite 6 hin weisende Lasche 42 angeformt. In der geschlossenen Klemmenposition - diese ist in der Figur 1 dargestellt - verschließt die Lasche 41 die Querverdrahtungsöffnung. In der geöffneten Klemmenposition, in Figur 4 dargestellt, ist der Klemmenrahmen 10 nach unten verschoben, die Lasche 42 gibt die Querverdrahtungsöffnung 40 jetzt frei.For this purpose, it is known to be formed on the clamping plate 12 a downwardly bent and thus to the mounting side 6 facing toward tab 42. In the closed terminal position - this is in the FIG. 1 shown - the tab 41 closes the cross-wiring opening. In the open terminal position, shown in Figure 4, the terminal frame 10 is moved down, the tab 42 is the cross-wiring opening 40 now free.

Für den Hintersteckschutz an der Leitereinführöffnung 29 ist die Anschlussklemme 8 mit einem Klemmenabdeckteil 19, das einen mit dem Klemmende 17 der Klemmschraube 16 gekoppelten Haltearm 20 und eine an dem Haltearm 20 angebrachte Abdeckplatte 21 zum Abdecken des Klemmraums 9 hat, ausgebildet. Bei geschlossener Anschlussklemme 8 verschließt die Abdeckplatte 21 die Leitereinführöffnung 29. Die Abdeckplatte besteht aus einem isolierenden Material und sorgt dadurch zusätzlich für einen Berührschutz gegen unbeabsichtigte Berührung stromführender Teile der Anschlussklemme 8 an der Einführöffnung 29. Im Bereich der Querverdrahtungsöffnung 40 ist ein Berührschutz in bekannter Weise durch wulstartig die Querverdrahtungsöffnung 40 umgebende Konturelemente gegeben.For the behind-the-ear protection at the conductor insertion opening 29, the connection terminal 8 is formed with a terminal cover part 19 which has a holding arm 20 coupled to the clamping end 17 of the clamping screw 16 and a cover plate 21 attached to the holding arm 20 for covering the clamping space 9. When the terminal 8 is closed, the cover plate 21 closes the conductor insertion opening 29. The cover plate is made of an insulating material and thereby additionally provides contact protection against inadvertent contact with live parts of the terminal 8 at the insertion opening 29. In the region of the cross-wiring opening 40 is a contact protection in a known manner given by beading the cross-wiring opening 40 surrounding contour elements.

Die Abdeckplatte 21 liegt an den Stirnseiten 13, 13' der Seitenplatten 15, 15' verschieblich geführt an. An der Abdeckplatte 21 sind lateral nach außen zu den Gehäusebreitseiten 3 hin federnde Haltearme 22, 22' ausgebildet. Das Gehäuse 2 ist mit medial zu den Haltearmen 22, 22' hin orientierten Anschlagsmitteln 23 ausgebildet. Wenn sich die Klemmschraube 18 in der ersten, geöffneten Position befindet, dann wirken an dem Klemmenabdeckteil 19 die federnden Haltearme 22, 22' mit den Anschlagsmitteln 23 zum Halten des Klemmenabdeckteils 19 zusammen, was insbesondere in der Figur 5 dargestellt ist.The cover plate 21 is located on the end faces 13, 13 'of the side plates 15, 15' slidably guided. On the cover plate 21 laterally outward to the housing broad sides 3 towards resilient support arms 22, 22 'are formed. The housing 2 is formed with stop means 23 oriented medially to the holding arms 22, 22 '. When the clamping screw 18 is in the first, open position, then act on the terminal cover 19, the resilient support arms 22, 22 'with the stop means 23 for holding the terminal cover 19 together, which is particularly in the FIG. 5 is shown.

Dadurch, dass die Abdeckplatte 21 an den Stirnseiten 13, 13' der Seitenplatten 15, 15' verschieblich geführt anliegt, bedeckt sie den Klemmenrahmen 10 von vorne, auch die Stirnseiten 13, 13' sind zumindest teilweise bedeckt, und es ist eine gute Führung des Klemmenabdeckteils 19, auch wenn der Klemmenrahmen 10 breit ist und einen großen Querschnitt hat, für die Einführung von Anschlussleitern mit einem größeren Durchmesser von bis zu 50 mm2, gegeben.The fact that the cover plate 21 on the end faces 13, 13 'of the side plates 15, 15' slidably guided, it covers the terminal frame 10 from the front, and the end faces 13, 13 'are at least partially covered, and it is a good guide of the terminal cover 19, even if the clamp frame 10 is wide and has a large cross-section, given for the introduction of connecting conductors with a larger diameter of up to 50 mm 2.

Es ist dabei nicht erforderlich, dass die Abdeckplatte 21 die Stirnseiten 13, 13' der Seitenplatten 15 vollständig bedeckt. Dies ist in einer vorteilhaften Ausführungsform möglich, dann erfüllt die Abdeckplatte zusätzlich noch die Funktion, den Klemmenrahmen auch an den Stirnseiten vollständig abzudecken. Die Funktion der Führung des Klemmenabdeckteils ist auch dann gegeben, wenn die Abdeckplatte 21 die Stirnseiten 13, 13' nur leicht überlappt. Auch eine kleine Überlappung kann ausreichen, um zu verhindern, dass die Abdeckplatte 21 an den Stirnseiten 13, 13' vorbei in den Klemmraum 9 des Klemmrahmens hinein gedrückt wird.It is not necessary that the cover plate 21, the end faces 13, 13 'of the side plates 15 completely covered. This is possible in an advantageous embodiment, then the cover also fulfills the function to completely cover the terminal frame on the front pages. The function of guiding the terminal cover part is also given when the cover plate 21 only slightly overlaps the end faces 13, 13 '. A small overlap may also be sufficient to prevent the cover plate 21 from being pressed past the end faces 13, 13 'into the clamping space 9 of the clamping frame.

Die an der Abdeckplatte 21 lateral nach außen zu den Gehäusebreitseiten 3 hin federnd ausgebildeten Haltearme 22, 22' bewirken eine vorteilhafte federnde Abstützung des Klemmenabdeckteils 19 an der Gehäusewand. Dadurch und auch im Zusammenwirken mit den medial zu den Haltearmen 22, 22' hin orientierten Anschlagsmitteln 23 wird die Klemmschraube 16 in der offenen Stellung gehalten, und dadurch kann verhindert werden, dass sich die Klemmschraube beispielsweise durch Erschütterungen selbst zudreht. Das ist von Vorteil, wenn das Installationsschaltgerät mit geöffneten Anschlussklemme an den Kunden ausgeliefert wird. Der Kunde kann dann sicher sein, dass er nach dem Einbau des Installationsschaltgerätes sofort die Anschlussleiter oder die Querverdrahtung einführen kann und nicht noch vorher zeitaufwändig die Öffnung der Anschlussklemme überprüfen oder gar die Anschlussklemme erst aufdrehen muss.The support arms 22, 22 'formed laterally on the cover plate 21 laterally outwards relative to the housing broad sides 3 effect an advantageous resilient support of the terminal cover part 19 on the housing wall. Thereby and also in cooperation with the medial to the support arms 22, 22 'out oriented stop means 23, the clamping screw 16 is held in the open position, and thereby can be prevented that the clamping screw, for example, by shaking itself. This is an advantage if the service switching device is delivered to the customer with the connection terminal open. The customer can then be sure that after installation of the service switching device, he can immediately insert the connection conductors or the cross-wiring and does not have to time-consuming check the opening of the connection terminal or even turn up the connection terminal first.

Wie die Figur 4 zeigt, befindet sich das Anschlagsmittel 23 im Bereich der Leitereinführöffnung 29.As the FIG. 4 shows, the stop means 23 is in the region of the conductor insertion opening 29th

Zur Ausbildung der federnden Haltearme 22, 22' befinden sich in der Abdeckplatte 21 schlitzartige Ausnehmungen 24, die von der der Klemmplatte 12 zugewandten unteren Querkante 25 der Abdeckplatte 21 ausgehend sich parallel zu der Breitseite 14 der Seitenplatte 15 in Richtung zu der der Frontseite 5 zugewandten oberen Querkante 26 der Abdeckplatte 21 hin erstrecken, und deren Abstand von der die untere und die obere Querkante 25, 26 verbindenden Längskanten 27, 27' der Abdeckplatte 21 die Breite des federnden Haltearms 22, 22' festlegt. Das ist eine besonders einfache Art, um federnde Haltearme an der Abdeckplatte auszubilden, ohne zusätzliche Teile anformen zu müssen. In vorteilhafter Weise besteht dabei die Abdeckplatte aus einem isolierenden Werkstoff mit guten federelastischen Eigenschaften.To form the resilient retaining arms 22, 22 'are in the cover plate 21 slit-like recesses 24, facing from the clamping plate 12 lower transverse edge 25 of the cover plate 21 starting parallel to the broad side 14 of the side plate 15 in the direction of the front side facing 5 upper transverse edge 26 of the cover 21 toward out, and their distance from the lower and the upper transverse edge 25, 26 connecting longitudinal edges 27th , 27 'of the cover plate 21 determines the width of the resilient support arm 22, 22'. This is a particularly simple way to form resilient retaining arms on the cover plate, without having to mold additional parts. In an advantageous manner, the cover plate consists of an insulating material with good elastic properties.

Die Haltearme 22, 22' sind an ihren freien Enden mit lateral nach außen zu den Gehäusebreitseiten 3 hin von den Längskanten 27, 27' abstehenden nasenartigen Vorsprüngen 28 ausgebildet. Die nasenartigen Vorsprünge eignen sich gut als Rastmittel, um die Abdeckplatte mit den Anschlagsmitteln zu verrasten, in der Position, wenn die Klemmschraube nach oben gedreht ist, um so ein selbständiges herabdrehen der Klemmschraube, etwa durch Erschütterungen, zu verhindern.The holding arms 22, 22 'are formed at their free ends with nose-like projections 28 projecting laterally outwards towards the housing broad sides 3 from the longitudinal edges 27, 27'. The nose-like projections are well suited as a locking means to lock the cover plate with the stop means in the position when the clamping screw is turned upwards, so as to prevent an independent turning down the clamping screw, such as by shocks.

Die Anschlagsmittel 23 sind an den Längskanten 30 der Leitereinführöffnung 29 in der die Schmalseite 4 des Gehäuses 2 bildenden Wand als in den Innenraum der Leitereinführöffnung 29 hervorstehende Stege ausgebildet. Diese sind sehr einfach beim Spritzgießen der Gehäuseteile anformbar.The stop means 23 are formed on the longitudinal edges 30 of the conductor insertion opening 29 in the narrow side 4 of the housing 2 forming wall as in the interior of the conductor insertion opening 29 protruding webs. These are very easy to mold during injection molding of the housing parts.

In der die Schmalseite 4 des Gehäuses 2 bildenden Wand in dem Bereich zwischen der oberen, der Frontseite 5 zugewandten Kante 31 der Gehäusezugangsöffnung 29 und der Frontseite 5 ist ein sich von der oberen, der Frontseite 5 zugewandten Kante 31 der Gehäusezugangsöffnung 29 aus zu der Frontseite 5 hin erstreckender Schlitz 32 ausgebildet. Der Schlitz kann auch als eine Tasche angesehen werden. Er dient zur Aufnahme der Abdeckplatte 21, wenn die Klemmschraube 16 in die erste, geöffnete Position, in der das Klemmende 17 von der Klemmplatte 12 entfernt ist, bewegt wird. In diese Tasche fährt die Abdeckplatte hinein, wenn die Klemmschraube herausgedreht wird, und wenn dann in der oberen Position der Klemmschraube die Abdeckplatte die obere Gewindeplatte des Klemmenrahmens überragt. Die Abdeckplatte ist dadurch auch in dieser Position noch zuverlässig im Gehäuse geführt.In the narrow side 4 of the housing 2 forming wall in the area between the upper, the front 5 facing edge 31 of the housing access opening 29 and the front 5 is a facing from the top, the front 5 edge 31 of the housing access opening 29 from the front 5 out extending slot 32 formed. The slot can also be considered as a bag. It serves to receive the cover plate 21 when the clamping screw 16 in the first, opened position in which the clamping end 17 is removed from the clamping plate 12 is moved. The cover plate moves into this pocket when the clamping screw is unscrewed, and then in the upper position of the clamping screw, the cover plate projects beyond the upper threaded plate of the clamping frame. The cover plate is thereby still reliably guided in the housing in this position.

An dem Klemmende 17 der Klemmschraube 16 ist unter Ausbildung eines stufenförmigen Absatzes 33 ein Koppelfortsatz 34 mit gegenüber dem Gewindeschaft 35 verringertem Durchmesser ausgebildet. Der Haltearm 20 des Klemmenabdeckteils 19 ist zur Kopplung mit der Klemmschraube 16 auf den Koppelfortsatz 34 aufgeschoben.At the terminal end 17 of the clamping screw 16 is a coupling shoulder 34 with respect to the threaded shaft 35 to form a stepped shoulder 33 formed reduced diameter. The holding arm 20 of the terminal cover part 19 is pushed onto the coupling extension 34 for coupling to the clamping screw 16.

Mit dem Koppelfortsatz 34 ist ein Druckstück 36 zum Andrücken eines Anschlussleiters zwischen der Klemmschraube 16 und der Klemmplatte 12 oder zwischen der Klemmschraube und dem Leiterstück 39 gekoppelt, wobei der Haltearm 20 zwischen dem Druckstück 36 und dem Absatz 33 am Klemmende 17 der Klemmschraube 16 unverlierbar an dem Koppelfortsatz 34 gehalten ist.With the coupling extension 34, a pressure piece 36 is coupled for pressing a connecting conductor between the clamping screw 16 and the clamping plate 12 or between the clamping screw and the conductor piece 39, wherein the holding arm 20 between the pressure piece 36 and the shoulder 33 at the clamping end 17 of the clamping screw 16 captive the coupling extension 34 is held.

Aufgrund der oben genannten vorteilhaften Ausgestaltungen wird eine sehr vorteilhafte Montagereihenfolge eröffnet. Zuerst wird dabei die Klemmschraube in das Gewinde in der oberen Gewindeplatte eingeschraubt. Als nächstes wird der Haltearm auf den Koppelfortsatz der Klemmschraube aufgeschoben. Der Haltearm kann dazu eine Öffnung mit einer Öffnungskontur haben, die in etwa der Außenkontur des Koppelfortsatzes entspricht. Danach wird das Druckstück über den unteren Teil des Koppelfortsatzes gesetzt. Der untere Teil des Koppelfortsatzes kann dazu einen anderen Durchmesser als der Teil des Koppelfortsatzes, an dem der Haltearm steckt, haben. Insbesondere kann der untere Teil des Koppelfortsatzes einen kleineren Durchmesser haben. Das Druckstück wird anschließend mit dem unteren Teil des Koppelfortsatzes vernietet oder verstemmt. Das Druckstück und der Haltearm und damit die Abdeckplatte sind nun mit der Klemmschraube unverlierbar verbunden. Weil die Klemmschraube zuvor in das Gewinde in der oberen Gewindeplatte eingeschraubt worden war und sich damit das Klemmende der Klemmschraube zwischen der oberen Gewindeplatte und der unteren Klemmplatte befindet, ist damit auch die Klemmschraube unverlierbar mit dem Klemmrahmen verbunden.Due to the above advantageous embodiments, a very advantageous assembly order is opened. First, the clamping screw is screwed into the thread in the upper threaded plate. Next, the retaining arm is pushed onto the coupling extension of the clamping screw. The holding arm may have an opening with an opening contour, which corresponds approximately to the outer contour of the coupling extension. Thereafter, the pressure piece is placed over the lower part of the coupling extension. The lower part of the coupling extension can for this purpose have a different diameter than the part of the coupling extension on which the holding arm is inserted. In particular, the lower part of the coupling extension may have a smaller diameter. The pressure piece is then riveted or caulked to the lower part of the coupling extension. The pressure piece and the retaining arm and thus the cover plate are now connected captively with the clamping screw. Because the clamping screw was previously screwed into the thread in the upper threaded plate and thus the clamping end of the clamping screw between the upper threaded plate and the lower clamping plate is, so that the clamping screw is captively connected to the clamping frame.

Gemäß einer weiteren vorteilhaften Ausführungsform ist der Haltearm zwischen dem Druckstück und dem Absatz am Klemmende der Klemmschraube aufgeklipst oder aufgesteckt und damit nicht unverlierbar gehalten. Der Haltearm kann dazu an seinem freien Ende eine gabelartige Aufweitung haben, mit den beiden Gabelzinken wird er dann an das Klemmende der Klemmschraube aufgesteckt. Die Gabelzinken haben in vorteilhafter Weise federelastische Eigenschaften, wodurch der Haltearm an dem Klemmfortsatz federnd verrasten kann.According to a further advantageous embodiment of the support arm is clipped or plugged between the pressure piece and the paragraph at the terminal end of the clamping screw and thus not held captive. The support arm can do this at its free end have a fork-like expansion, with the two forks it is then attached to the terminal end of the clamping screw. The forks have in an advantageous manner spring elastic properties, whereby the support arm can latch on the clamping extension resiliently.

Mit dieser vorteilhaften Ausgestaltung wird eine andere vorteilhafte Montagereihenfolge eröffnet. Zuerst wird dabei auch hier die Klemmschraube in das Gewinde in der oberen Gewindeplatte eingeschraubt. Als nächstes wird hier nun das Druckstück über den unteren Teil des Koppelfortsatzes gesetzt und anschließend mit dem unteren Teil des Koppelfortsatzes vernietet oder verstemmt. So ist das Druckstück mit der Klemmschraube unverlierbar verbunden. Weil die Klemmschraube zuvor in das Gewinde in der oberen Gewindeplatte eingeschraubt worden war und sich damit das Klemmende der Klemmschraube zwischen der oberen Gewindeplatte und der unteren Klemmplatte befindet, ist damit auch die Klemmschraube unverlierbar mit dem Klemmrahmen verbunden. Nun wird der Haltearm auf den Koppelfortsatz der Klemmschraube aufgeschoben, in den Bereich des oberen Teils des Koppelfortsatzes, zwischen das Druckstück und den Absatz am Klemmende der Klemmschraube, und dort federnd verrastet, wie oben beschrieben.With this advantageous embodiment, another advantageous assembly order is opened. First, the clamping screw is screwed into the thread in the upper threaded plate. Next, the pressure piece is now placed over the lower part of the coupling extension and then riveted or caulked to the lower part of the coupling extension. Thus, the pressure piece is captively connected to the clamping screw. Because the clamping screw was previously screwed into the thread in the upper threaded plate and thus the clamping end of the clamping screw between the upper threaded plate and the lower clamping plate is, so that the clamping screw is captively connected to the clamping frame. Now, the support arm is pushed onto the coupling extension of the clamping screw, in the region of the upper part of the coupling extension, between the pressure piece and the paragraph at the terminal end of the clamping screw, and there resiliently locked, as described above.

Beim Öffnen der Klemmschraube, also bei Herausdrehen, kann die Klemmschraube in einen Freilauf gelangen, was bedeutet, dass das Gewinde der Klemmschraube mit dem Gewinde in der oberen Gewindeplatte im Zustand des Freilaufes nicht mehr in Eingriff miteinander stehen. Der Freilauf verhindert in vorteilhafter Weise ein Verklemmen des Abdeckteils und des Druckstücks mit dem Klemmenrahmen.When opening the clamping screw, so when unscrewing, the clamping screw can get into a freewheel, which means that the thread of the clamping screw with the thread in the upper threaded plate in the state of the freewheel are no longer engaged. The freewheel advantageously prevents jamming of the cover and the pressure piece with the terminal frame.

Eine an der Frontseite 5 gelegene Zugangsöffnung 37 zu dem Betätigungsende 18 der Klemmschraube 16 ist mit einer die Zugangsöffnung 37 kranzförmig umgebenden, erhabenen Wulst 38 ausgebildet. Diese Wulst 38 erhöht die Fingersicherheit, also den Berührschutz vor versehentlichem Berühren der möglicherweise stromführenden Klemmschraube mit dem Finger.
