Beschreibung  description
Die Erfindung betrifft ein Installationsschaltgerät mit einem schraubenlosen Klemmanschluss, mit einer Klemmfeder, die zwei benachbarte Klemmschenkel hat, und mit einem schwenkbar mit dem Gehäuse gekoppelten Klemmenabdeckteil, gemäß dem Oberbegriff des Anspruchs 1 . The invention relates to an installation switching device with a screwless terminal connection, with a clamping spring, which has two adjacent clamping legs, and with a pivotally coupled to the housing terminal cover, according to the preamble of claim 1.
Ein gattungsgemäßes Installationsschaltgerät, welches beispielsweise ein Leitungsschutzschalter ist, ist beispielsweise aus der DE 10 2006 047 254 B3 bekannt. Das dort gezeigte Installationsschaltgerät hat ein Gehäuse mit einer vorderen und hinteren Frontseite, einer Befestigungsseite, vorderen und hinteren Schmalseiten und Breitseiten, Es hat einen schraubenlosen Klemmenanschluss mit einer Klemmfeder zum Anschließen von Anschlussleitern, der in einem Klemmenanschlussraum des Gehäuses lagefixiert ist. Der Klemmenanschlussraum ist durch die Gehäusebreitseiten seitlich begrenzt und wenigstens zur vorderen Frontseite hin offen, und die Öffnung des Klem- menanschlussraums ist durch ein schwenkbar mit dem Gehäuse verbundenes Klemmenabdeckteil bedeckbar, welches eine Anschlussfläche mit einer der Anzahl anzuschließender Anschlussleiter entsprechenden Anzahl von Anschlussöffnungen sowie an jeder Anschlussöffnung angeformte Führungsmittel für die Anschlussleiter aufweist. An das Abdeckteil sind Federbetätigungsmittel angeformt und so ausgebildet, dass sie beim Verschwenken des Abdeckteils gegen die Klemmfeder diese öffnend beaufschlagen. A generic service switching device, which is for example a circuit breaker, is known for example from DE 10 2006 047 254 B3. The installation switching device shown there has a housing with a front and rear front, a mounting side, front and rear narrow sides and broadsides, It has a screwless terminal connection with a clamping spring for connecting connecting leads, which is fixed in position in a terminal connection space of the housing. The terminal connection space is bounded laterally by the housing broad sides and open at least towards the front front, and the opening of the terminal connection space can be covered by a terminal cover part which is pivotally connected to the housing and has a connection surface with a number of connection openings corresponding to the number of connection leads to be connected and at each Connecting opening integrally formed guide means for the connection conductors. Federbetätigungsmittel are formed on the cover and formed so that they act upon opening of the cover against the clamping spring opening.
Auch die DE 10 2006 047 255 A1 zeigt ein Installationsschaltgerät mit einem Klemmanschluss, mit dem wenigstens zwei Anschlussleiter an das Installationsschaltgerät anschließbar sind, mit einer als Druckfeder auf die Leiterenden einwirkenden Klemmfeder zum Festklemmen wenigstens eines Leiterendes an einem Widerlager, wobei, der Klemmanschluss eine Stromschiene mit einem Anschlussende und einem daran anschließenden Ableitbereich umfasst, die Stromschiene am Anschlussende eine fensterartige Aussparung mit einer Stützkante und einer der Stützkante gegenüberliegenden Klemmkante am Übergang des Anschlussendes in den Ableitbereich aufweist, die Klemmfeder einen Stützschenkel aufweist, mit dem sie an der Stützkante der Stromschiene abgestützt ist, und wobei sich an den Stützschenkel ein Bogenstück und daran ein längsgeschlitzter Klemmschenkel mit zwei dicht aneinander liegenden, aber unabhängig voneinander klemmfähigen Teil-Federn anschließt, so dass zwei Leiterenden unabhängig voneinander zwischen dem Klemmschenkel und der Klemmkante als Widerlager festklemmbar sind. DE 10 2006 047 255 A1 also shows an installation switching device with a terminal connection, with which at least two connecting conductors can be connected to the service switching device, with a clamping spring acting as a compression spring on the conductor ends for clamping at least one conductor end to an abutment, wherein the terminal connection is a busbar with a connection end and one at it includes subsequent lead-off, the busbar at the terminal end has a window-like recess with a support edge and a clamping edge opposite the clamping edge at the junction of the terminal end in the Ableitbereich, the clamping spring has a support leg, with which it is supported on the support edge of the busbar, and wherein at the support leg a curve piece and a longitudinally slotted clamping leg with two close together, but independently clampable part springs followed, so that two conductor ends are independently clamped between the clamping legs and the clamping edge as an abutment.
Die gattungsbildenden Merkmale der DE 10 2006 047 255 A1 und der DE 10 2006 047 254 B3 sollen ausdrücklich im Offenbarungsgehalt der vorliegenden Erfindung mit umfasst sein. The generic features of DE 10 2006 047 255 A1 and DE 10 2006 047 254 B3 are expressly included in the disclosure of the present invention.
Bei den bekannten Installationsschaltgeräten kann es irrtümlich vorkommen, dass beispielsweise ein flexibler Leiter beim Einführen in die Anschlussklemme zwischen die beiden Klemmschenkel rutschen und sich dabei so verklemmen kann, dass der Leiter nicht mehr gelöst werden kann. In the known installation switching devices, it may happen by mistake that, for example, a flexible conductor slip during insertion into the terminal between the two clamping legs and can become jammed so that the head can not be solved.
Es ist daher die Aufgabe der vorliegenden Erfindung, ein Installationsschaltgerät hinsichtlich des schraubenlosen Klemmanschlusses so zu verbessern, dass ein fehlerhaftes Einführen von Anschlussleitern vermieden und dadurch die Bediensicherheit des Gerätes erhöht wird. It is therefore an object of the present invention to improve a service switching device with respect to the screwless terminal connection so that a faulty insertion of connecting conductors avoided and thereby the operating safety of the device is increased.
Die Aufgabe wird gelöst durch ein Installationsschaltgerät mit den Merkmalen des Anspruchs 1 . The object is achieved by an installation switching device having the features of claim 1.
Erfindungsgemäß also sind die Klemmschenkel durch einen Schlitz getrennt, und mit dem Klemmenabdeckteil ist eine Trennplatte gekoppelt, deren freies Ende in dem Schlitz zwischen den beiden Klemmschenkeln geführt ist. Die Trennplatte kann auch als Nase bezeichnet werden, die vom Federbetätigungshebel ausgehend zwischen die beiden Klemmschenkel geführt ist. Der erfindungsgemäße Vorteil liegt darin, dass diese Nase verhindert, dass ein Leiter, insbesondere ein dünner Leiter, so schräg in die Anschlussöffnung an dem Klemmenabdeckteil eingesteckt werden kann, dass er sich mit dem anderen Federschenkel verklemmt. Eine Fehlverdrahtung ist damit vermieden und die Bediensicherheit ist erhöht. According to the invention, therefore, the clamping legs are separated by a slot, and with the terminal cover is coupled a partition plate whose free end is guided in the slot between the two clamping legs. The partition plate can also be referred to as a nose, which is guided by the spring actuating lever, starting between the two clamping legs. The advantage of the invention is that this nose prevents a conductor, in particular a thin conductor, can be inserted so obliquely into the connection opening on the terminal cover that he is jammed with the other spring leg. A miswiring is thus avoided and the operator safety is increased.
Gemäß einer vorteilhaften Ausführungsform werden die Klemmschenkel durch einen breiten Schlitz getrennt. Sie sind gemäß einer vorteilhaften Ausführungsform an einer gemeinsamen Stützkante angeformt und im Abstand des Schlitzes parallel zueinander verlaufend angebracht. Eine erfindungsgemäße Klemmfeder kann im Anschluss an die Stützkante zunächst einen Stützschenkel haben der über ein Bogenstück in die beiden durch den Schlitz getrennten Klemmschenkel übergeht. Der Schlitz kann sich aber auch über das Bogenstück hin in den Stützschenkel ziehen, so dass an den Stützschenkel zwei mehr oder weniger voneinander unabhängige Federschenkel, jeder umfassend einen Stützschenkel, ein Bogenstück und einen Klemmschenkel, angeformt sind. Die Klemmschenkel sind jedenfalls durch den Schlitz so weit auseinander gehalten, dass sie sich unabhängig jeweils von dem anderen Klemmschenkel bewegen lassen, und dass sich ein Leiterende, das zwischen beide Klemmschenkel gerät, dort nicht festgeklemmt werden kann, sondern gewissermaßen durchrutschen würde. According to an advantageous embodiment, the clamping legs are separated by a wide slot. They are integrally formed according to an advantageous embodiment of a common support edge and mounted parallel to each other at a distance of the slot. A clamping spring according to the invention may, following the supporting edge, initially have a supporting leg which merges via a curved piece into the two clamping legs separated by the slot. However, the slot can also pull over the elbow into the support leg, so that two more or less independent spring legs, each comprising a support leg, a bend and a clamping leg, are integrally formed on the support leg. The clamping legs are anyway so far apart through the slot that they can be independently moved by the other clamping leg, and that a conductor end, which gets between the two clamping legs, there can not be clamped, but in a sense would slip through.
Gemäß einer vorteilhaften Ausführungsform ist der Abstand zwischen den Klemmschenkeln in einem ersten Teilbereich an den freien Enden der Klemmschenkel auf die Dicke der Trennplatte abgestimmt, so dass die Trennplatte zwischen den freien Enden der Klemmschenkel reibungsfrei gleiten kann. According to an advantageous embodiment, the distance between the clamping legs in a first portion at the free ends of the clamping legs is adapted to the thickness of the partition plate, so that the partition plate between the free ends of the clamping legs can slide smoothly.
Gemäß einer vorteilhaften Ausführungsform der Erfindung ist der Abstand zwischen den Klemmschenkeln in einem zweiten Teilbereich, der sich an den ersten Teilbereich anschließt, größer als die Dicke der Trennplatte, so dass die Trennplatte in dem zweiten Teilbereich einfach eingeführt werden kann. Die Ausführung des Schlitzes kann erfindungsgemäß so gestaltet werden, dass beim Montieren des Klemmenabdeckteils, welches gleichzeitig die Funktion des Federbetätigungshebels ausübt, die Nase in einen breiteren Teil des Schlitzes eintaucht und dann beim Einschwenken in einen schmäleren Teil des Schlitzes geführt wird. According to an advantageous embodiment of the invention, the distance between the clamping legs in a second partial area, which adjoins the first partial area, is greater than the thickness of the separating plate, so that the separating plate can be easily inserted in the second partial area. The design of the slot according to the invention can be designed so that when mounting the terminal cover, which at the same time performs the function of the spring actuating lever, the nose is immersed in a wider part of the slot and then guided during pivoting in a narrower part of the slot.
Gemäß einer weiteren vorteilhaften Ausführungsform der Erfindung trägt die Trennplatte an ihrem freien Ende einen nasenförmig abstehenden Ansatz. Gemäß einer weiteren vorteilhaften Ausführungsform der Erfindung ist ein zweites Klemmenabdeckteil mit dem Gehäuse fest gekoppelt, das wenigstens eine Anschlussöffnung und wenigstens ein Führungsmittel für wenigstens einen Anschlussleiter hat. Dabei ergänzen sich das schwenkbar mit dem Gehäuse gekoppelte Klemmenabdeckteil und das zweite, mit dem Gehäuse fest gekoppelte Abdeckteil, zur Abdeckung des Klemmenanschlussraums. Der Anschlussleiter ist in dem Führungsmittel des zweiten, mit dem Gehäuse fest gekoppelten Abdeckteil geführt. Beim Verschwenken des schwenkbar mit dem Gehäuse gekoppelten Klemmenabdeckteils kann dieses teilweise an dem mit dem Gehäuse fest gekoppelten Abdeckteil entlang gleiten. According to a further advantageous embodiment of the invention, the partition plate carries at its free end a nose-shaped protruding approach. According to a further advantageous embodiment of the invention, a second terminal cover part is fixedly coupled to the housing, which has at least one connection opening and at least one guide means for at least one connection conductor. In this case, the terminal cover part pivotally coupled to the housing and the second cover part fixedly coupled to the housing complement each other to cover the terminal connection space. The connection conductor is guided in the guide means of the second, with the housing firmly coupled cover. When pivoting the pivotally coupled to the housing terminal cover part of this can partially slide along the firmly coupled to the housing cover.
Das schwenkbar mit dem Gehäuse gekoppelte Klemmenabdeckteil kann auch noch wenigstens ein Federbetätigungsmittel aufweisen, mit dem beim Verschwenken des schwenkbar mit dem Gehäuse gekoppelten Klemmenabdeckteils die Klemmfeder für das Einführen eines Anschlussleiters geöffnet wird. Die Funktionen„Führen des Anschlussleiters" und„Öffnen der Klemmfeder" ist hier auf zwei Bauteile verteilt, nämlich auf das schwenkbar mit dem Gehäuse gekoppelte Klemmenabdeckteil und auf das zweite, fest mit dem Gehäuse gekoppelte Abdeckteil. The terminal cover part pivotally coupled to the housing may also have at least one spring actuation means with which the clamping spring for the insertion of a connection conductor is opened when the terminal cover part is pivotally coupled to the housing.

Figur 1 zeigt eine Teilschnittansicht eines geöffneten Installationsschaltgerätes, beispielsweise eines Leitungsschutzschalters. Das Installationsschaltgerät 1 besitzt ein aus zwei längs einer Trennfuge zusammengefügten Gehäuseteilen 26 (von denen in der Figur 1 nur ein Gehäuseteil in teilgeschnittener Ansicht dargestellt ist) gebildetes Isolierstoffgehäuse mit einer vorderen Frontseite 27, einer hinteren Frontseite 28, einer Befestigungsseite 29, einer vorderen Schmalseite 30, einer hinteren Schmalseite 31 , sowie Breitseiten 32 . FIG. 1 shows a partial sectional view of an opened service switching device, for example a circuit breaker. The installation switching device 1 has an assembled from two along a parting line housing parts 26 (of which only a housing part is shown in partial section in Figure 1) formed Isolierstoffgehäuse with a front front side 27, a rear front side 28, a mounting side 29, a front narrow side 30th , a rear narrow side 31, and broadsides 32nd
Im Bereich der hinteren Schmalseite 31 befindet sich ein Klemmenanschlussraum mit einem schraubenlosen Klemmenanschluss 1 1 . Der Klemmenanschlussraum ist seitlich, also zur Breitseite hin, durch die Gehäusebreitseiten des Isolierstoffgehäuses begrenzt. Zur vorderen Frontseite 27 hin ist durch eine Ausnehmung in der hinteren Frontseite 28 des Gehäuseteiles 26 eine Öffnung des Klemmenanschlussraums gebildet, durch die hindurch der in dem Klemmenanschlussraum lagefixierte Klemmenanschluss 1 1 für den Anschluss von Anschlussleitern zugänglich ist. Die Öffnung des Klemmenanschlussraumes ist durch ein schwenkbar mit dem Gehäuse 26 verbundenes Klemmenabdeckteil 15 bedeckt. Das Klemmenabdeckteil 15 ist in etwa L-förmig ausgebildet, wobei die beiden Schenkel durch winklig aufeinander stehende Abdeckplatten gebildet sind. Eine erste Abdeckplatte 35 deckt den Klemmenan- schlussraum zur hinteren Frontseite 28 hin ab und weist eine Anschlussfläche auf, mit zwei Anschlussöffnungen 16, wobei durch jede der Anschlussöffnungen 16 ein Anschlussleiter angeschlossen werden kann. Die zweite Abdeckplatte 36 deckt den Klem- menanschlussraum zur hinteren Schmalseite 31 hin ab und weist eine von außen zugängliche, manuell betätigbare Druckfläche sowie einen Schlitz 37 zum Einführen eines Betätigungswerkzeugs, beispielsweise eines Schraubendrehers, auf. An ihrer freien Kante besitzt die zweite Abdeckplatte 36 eine halboffene, röhrenartige Höhlung 33, mit der sie in einem mit der Breitseite 32 des Gehäuses 26 verbundenen Gelenkzapfen 34 drehbar gelagert ist. Durch Druck auf die Druckfläche kann das Klemmenabdeckteil 15 somit um die freie Kante der zweiten Abdeckplatte 36 in Richtung auf die Klemmfeder 12 hin verschwenkt werden. In the region of the rear narrow side 31 is a terminal connection space with a screwless terminal connection 1 1. The terminal connection space is laterally, ie towards the broad side, limited by the housing broad sides of the insulating material. Towards the front front side 27, an opening of the terminal connection space is formed through a recess in the rear front side 28 of the housing part 26, through which the terminal connection 1 1 fixed in position in the terminal connection space is accessible for the connection of connection conductors. The opening of the terminal connection space is covered by a terminal cover member 15 pivotally connected to the housing 26. The terminal cover 15 is formed approximately L-shaped, wherein the two legs are formed by angularly stacked cover plates. A first cover plate 35 covers the terminal connection space towards the rear front side 28 and has a connection surface with two connection openings 16, wherein a connection conductor can be connected through each of the connection openings 16. The second cover plate 36 covers the terminal connecting space to the rear narrow side 31 out and has an externally accessible, manually operable pressure surface and a slot 37 for insertion of an actuating tool, such as a screwdriver on. At its free edge, the second cover plate 36 has a semi-open, tubular cavity 33, with which it is rotatably mounted in a connected to the broad side 32 of the housing 26 pivot pin 34. By pressure on the pressure surface, the terminal cover 15 can thus be pivoted about the free edge of the second cover plate 36 in the direction of the clamping spring 12 out.
An der ersten Abdeckplatte 35 des Abdeckteiles 15 sind, ausgerichtet auf die Klemmfeder 12, an jeder der Anschlussöffnungen 16 röhrenartige, einen Einführkanal bildende Hohlkörper 17 angebracht. Diese dienen gleichzeitig als Führungsmittel für den einzuführenden Anschlussleiter, und als Federbetätigungsmittel. Wenn das Abdeckteil 15 durch Druck auf die Druckfläche um den Gelenkzapfen 34 in Richtung auf die Klemmfeder 12 hin verschwenkt wird, so drücken die Hohlkörper bzw. Führungsmittel 17 den Klemmschenkel 13, 14 der Klemmfeder 12 von der Klemmkante der Stromschiene weg, so dass zwischen der Klemmkante und dem Klemmschenkel Raum zum Einführen des abisolierten Anschlussleiterendes des Anschlussleiters entsteht. At the first cover plate 35 of the cover 15 are aligned with the clamping spring 12, at each of the connection openings 16 tubular, an insertion channel forming hollow body 17 is attached. These also serve as guide means for the lead to be inserted, and as spring actuation means. When the cover member 15 is pivoted by pressure on the pressure surface around the pivot pin 34 in the direction of the clamping spring 12 out, press the hollow body or guide means 17, the clamping legs 13, 14 of the clamping spring 12 away from the clamping edge of the busbar, so that between the Clamping edge and the clamping leg space for inserting the stripped terminal conductor end of the connecting conductor is formed.
Der Klemmenanschluss 1 1 umfasst eine Stromschiene und eine Klemmfeder 12. Die Stromschiene umfasst eine fensterartige Aussparung mit einer Stützfläche 38 und einer der Stützfläche 38 gegenüberliegenden Klemmfläche 39. Die Klemmfeder 12 weist einen Stützschenkel 40 auf, mit dem sie an der Stützfläche 38 abgestützt ist. Die AbStützung kann so erfolgen, dass der Stützschenkel 40 an seinem freien Ende eine Aufkantung aufweist, mit der er die Stützfläche 38 zum Zwecke des Abstützens teilweise umfasst. An den Stützschenkel 40 schließt sich ein Bogenstück 41 und daran ein Klemm- schenke! 13, 14 an. Das Leiterende eines Anschlussleiters wird von der Seite des Bo- genstücks 41 her in die fensterartige Aussparung eingeführt und ist zwischen dem freien Ende des Klennnnschenkels 13, 14 und der als Widerlager fungierenden Klemmflä- che 39 festklennnnbar. Das freie Ende des Klennnnschenkels 13, 14 durchgreift dabei die fensterartige Aussparung. The terminal connection 1 1 comprises a busbar and a clamping spring 12. The busbar comprises a window-like recess with a support surface 38 and a support surface 38 opposite clamping surface 39. The clamping spring 12 has a support leg 40, with which it is supported on the support surface 38. The support can be made so that the support leg 40 has at its free end a raised edge, with which it includes the support surface 38 for the purpose of supporting partially. At the support leg 40, a curved piece 41 and closes it a clamping piece Donate! 13, 14 on. The conductor end of a connection conductor is inserted into the window-like recess from the side of the sheet piece 41 and can be clamped between the free end of the clamping leg 13, 14 and the clamping surface 39 acting as an abutment. The free end of Klennnnschenkels 13, 14 passes through the window-like recess.
Die Klemmschenkel 13, 14 sind durch einen Schlitz 18 getrennt, so dass sie als zwei unabhängig voneinander klemmfähige Teilfedern 13, 14 ausgebildet sind, mit denen unabhängig voneinander zwei Anschlussleiter angeklemmt werden können. The clamping legs 13, 14 are separated by a slot 18 so that they are formed as two independently clampable part springs 13, 14, with which two connection conductors can be clamped independently of each other.
Mit der ersten Abdeckplatte 35 des Klemmenabdeckteils 15 ist eine Trennplatte 19 gekoppelt, hier ist sie angeformt, deren freies Ende in dem Schlitz 18 zwischen den beiden Klemmschenkeln 13, 14 geführt ist. With the first cover plate 35 of the terminal cover 15, a partition plate 19 is coupled, here it is formed, the free end is guided in the slot 18 between the two clamping legs 13, 14.
Die Klemmschenkel 13, 14 sind somit an der gemeinsamen Stützkante 20 und in etwa im Abstand des Schlitzes 18 parallel zueinander verlaufend angebracht. The clamping legs 13, 14 are thus attached to the common support edge 20 and approximately at a distance of the slot 18 extending parallel to each other.
Der Abstand zwischen den Klemmschenkeln 13, 14 ist in einem ersten Teilbereich 21 an den freien Enden 22, 23 der Klemmschenkel 13, 14 auf die Dicke der Trennplatte 19 abgestimmt, so dass die Trennplatte 19 zwischen den freien Enden 22, 23 der Klemmschenkel 13, 14 reibungsfrei gleiten kann. The distance between the clamping legs 13, 14 is in a first portion 21 at the free ends 22, 23 of the clamping legs 13, 14 matched to the thickness of the partition plate 19, so that the partition plate 19 between the free ends 22, 23 of the clamping legs 13, 14 can slide smoothly.
Der Abstand zwischen den Klemmschenkeln 13, 14 ist in einem zweiten TeilbereichThe distance between the clamping legs 13, 14 is in a second portion
24, der sich an den ersten Teilbereich 21 anschließt, größer als die Dicke der Trennplatte 19, so dass die Trennplatte 19 in dem zweiten Teilbereich 24 einfach eingeführt werden kann. 24, which adjoins the first portion 21, greater than the thickness of the partition plate 19, so that the partition plate 19 in the second portion 24 can be easily inserted.
Die Trennplatte 19 trägt an ihrem freien Ende einen nasenförmig abstehenden AnsatzThe partition plate 19 carries at its free end a nose-shaped protruding approach
25, der in Richtung auf die zweite Abdeckplatte 36 hin weisend angeformt ist. Beim Montieren des Klemmenabdeckteils 15 taucht der nasenformige Ansatz 25 zunächst in den breiteren, zweiten Teilbereich 24 des Schlitzes 18 ein, und wird dann beim Einschwenken in den schmäleren, ersten Teilbereich 21 des Schlitzes 18 geführt. 25, which is integrally formed pointing in the direction of the second cover plate 36. When mounting the terminal cover 15, the nose-shaped projection 25 first dives into the wider, second portion 24 of the slot 18, and is then guided during pivoting into the narrower, first portion 21 of the slot 18.
Vorteilhafterweise verhindert der nasenförmig abstehende Ansatz 25, dass ein Leiter, insbesondere ein dünner Anschlussleiter, so schräg in eine der Anschlussöffnungen 16 in dem Klemmenabdeckteil 15 eingesteckt werden kann, dass er sich mit dem anderen Klemmschenkel im ersten, schmalen Teilbereich 21 des Schlitzes zwischen den beiden Klemmfedern 13, 14 verklemmen kann. Advantageously, the nose-shaped protruding projection 25 prevents a conductor, in particular a thin connection conductor, from slanting into one of the connection openings 16 can be inserted in the terminal cover 15 that he can jam with the other clamping leg in the first, narrow portion 21 of the slot between the two clamping springs 13, 14.
Es werden nun die Figuren 4 und 5 betrachtet. Diese zeigt eine Teilschnittansicht eines geöffneten Installationsschaltgerätes mit einer Ausführungsform eines erfindungsgemäßen Klemmenanschlusses, bei dem ein zweites, mit dem Gehäuse fest gekoppeltes, Klemmenabdeckteil 42 vorhanden ist. Das schwenkbar mit dem Gehäuse gekoppelte Klemmenabdeckteil 15' entspricht dem Klemmenabdeckteil 15 in der Ausführungsform nach Fig. 1 bis 3, es trägt die Trennplatte 19. In der in der Figuren 4 und 5 gezeigten Ausführungsform befinden sich die Anschlussöffnungen 16' in dem mit dem Gehäuse fest gekoppelten Klemmenabdeckteil 42, siehe insbesondere Fig. 5, die die zweite Ausführungsform des Klemmenanschlusses ohne das schwenkbar mit dem Gehäuse gekoppelte Klemmenabdeckteil 15' zeigt. Es können sich auch die Führungsmittel an dem mit dem Gehäuse fest gekoppelten Klemmenabdeckteil 42 befinden, sie sind hier in den Figuren 4 und 5 allerdings nicht dargestellt. The figures 4 and 5 will now be considered. This shows a partial sectional view of an open service switching device with an embodiment of a terminal connection according to the invention, in which a second, with the housing firmly coupled, terminal cover 42 is present. The terminal cover member 15 'pivotally coupled to the housing corresponds to the terminal cover member 15 in the embodiment of Figs. 1 to 3 supporting the partition plate 19. In the embodiment shown in Figs. 4 and 5, the terminal openings 16' are in the housing firmly coupled terminal cover member 42, see in particular Fig. 5, which shows the second embodiment of the terminal terminal without the terminal cover 15 'pivotally coupled to the housing. The guide means may also be located on the terminal cover part 42 firmly coupled to the housing, but they are not shown here in FIGS. 4 and 5.
An dem in den Figuren 4 und 5 gezeigten Klemmenanschluss können zwei Anschlussleiter an das Installationsschaltgerät angeschlossen werden. Er hat eine als Druckfeder auf die Leiterenden einwirkende Klemmfeder 12 zum Festklemmen wenigstens eines Leiterendes an einem Widerlager.
