Description

Die Erfindung bezieht sich auf ein Schaltgerät mit einem im Querschnitt im wesentlichen recht­eckigen Gehäuse, mit einem Betätigungsvorsatz auf der Vorderseite des Gehäuses, der auf mindestens eine Hauptkontaktbrücke einwirkt, welche in dem Gehäuse zwischen zwei Schaltstellungen beweglich geführt ist, wobei zu jeder Hauptkontaktbrücke zwei Festkontaktschienen in dem Gehäuse gehalten sind, die im Bereich zweier einander gegenüber­liegender Seitenwände des Gehäuses mittels An­schlußschrauben mit elektrischen Anschlußleitungen verbindbar sind.The invention relates to a switching device with a housing which is essentially rectangular in cross section, with an actuating attachment on the front of the housing which acts on at least one main contact bridge, which is movably guided in the housing between two switching positions, two fixed contact rails for each main contact bridge in the housing are held, which can be connected in the region of two mutually opposite side walls of the housing by means of connecting screws with electrical connecting lines.

Schaltgeräte der vorgenannten Gattung müssen in der Praxis auf die unterschiedlichste Weise montiert werden. Man kann dabei aber grundsätz­lich zwischen zwei Montagearten unterscheiden. Bei der einen Montageart ist das eigentliche Schalt­gerät hinter einer Montageplatte befestigt, wobei der Betätigungsvorsatz auf der anderen, der Be­dienungsseite der Montageplatte liegt und durch eine Bohrung oder eine sonstige Öffnung in der Montageplatte mit geeigneten Verbindungselementen mit dem eigentlichen Schaltgerät verbunden ist. Diese Art der Montage der Schaltgeräte wird viel­fach bei Schalttafeln oder Schaltpulte angewendet, wenn die Schaltgeräte schnell zugänglich sein sollen. Eine grundsätzlich andere Art der Montage der Schaltgeräte ist gegeben, wenn diese zum Beispiel reihenweisen neben-und übereinander inner­ halb beispielsweise eines Schaltschrankes anzu­ordnen sind. In diesem Falle verwendet man zur reihenweisen Befestigung der Schaltgeräte viel­fach Normtragschienen, die dann ihrerseits bei­spielsweise auf der Innenwand eines Schalt­schrankes befestigt sind, oder man montiert die Schaltgeräte direkt auf einer Tragplatte, so daß die Rückseite des betreffenden Schaltgerätes auf der Platte zur Anlage kommt.Switchgear of the aforementioned type have to be installed in a variety of ways in practice. You can basically distinguish between two types of installation. In one type of installation, the actual switching device is fastened behind a mounting plate, the actuating attachment being on the other, the operating side of the mounting plate and connected to the actual switching device by means of suitable connecting elements through a hole or another opening in the mounting plate. This type of assembly of the switchgear is often used for switchboards or control panels if the switchgear is to be quickly accessible. A fundamentally different type of assembly of the switchgear is given if, for example, they are arranged in rows next to and above one another inside half of a control cabinet are to be arranged. In this case, standard mounting rails are often used for fastening the switchgear in rows, which in turn are then attached, for example, to the inner wall of a control cabinet, or the switchgear is mounted directly on a support plate, so that the rear of the switchgear concerned comes to rest on the plate.

Die Schaltgeräte müssen mit einer Anzahl An­schlußschrauben für die elektrischen Anschluß­leitungen versehen sein. Das können beispiels­weise je Schaltgerät sechs Anschlußschrauben sein oder auch eine wesentlich größere Anzahl. Ein Problem ist nun darin zu sehen, daß die Schalt­geräte zunächst fest montiert werden müssen, be­vor die elektrischen Anschlußleitungen angebracht und durch die Anschlußschrauben fest angezogen bzw. eingeklemmt werden. Bei der Montage der Schaltgeräte nach der oben zuerst erläuterten Montageart, nämlich auf der Rückseite einer Montageplatte, können die Anschlußschrauben praktisch nur von der Rückseite des Schaltgerätes her er­reicht und betätigt werden. Bei der anderen Montageart können die Anschlußschrauben aber praktisch nur von der Vorderseite des Schaltge­rätes aus mittels Schraubenzieher betätigt werden. Die bisher bekannten Schaltgeräte wurden von vorn­herein entweder nur für die eine oder nur für die andere Montageart ausgerüstet. Dies hat eine Reihe von Nachteilen zur Folge, zum Beispiel eine große Lagerhaltung beim Hersteller der Schaltgeräte, um die für die jeweilige Montageart passenden Schalt­geräte bereitstellen zu können.The switchgear must be provided with a number of connection screws for the electrical connection lines. This can be, for example, six connecting screws per switching device or a much larger number. A problem can now be seen in the fact that the switchgear must first be firmly installed before the electrical connecting lines are attached and firmly tightened or clamped by the connecting screws. When assembling the switchgear according to the assembly method explained above, namely on the back of a mounting plate, the connection screws can practically only be reached and actuated from the back of the switchgear. With the other type of mounting, the connection screws can practically only be operated from the front of the switching device using a screwdriver. The previously known switchgear was equipped from the outset either for one or for the other type of installation. This has a number of disadvantages, for example a large inventory at the switchgear manufacturer in order to be able to provide the switchgear suitable for the respective type of installation.

Der Erfindung liegt dem gegenüber die Aufgabe zugrunde, ein Schaltgerät zu schaffen, welches auf einfache Weise auf die verschiedenartigen Montagearten umstellbar ist.The invention is based on the object to provide a switching device which can be easily converted to different types of mounting.

Die gestellte Aufgabe wird, ausgehend von dem zu Anfang beschriebenen Schaltgerät, dadurch gelöst, daß die Anschlußschrauben in separaten Gehäuseböckchen untergebracht sind, die wahl­weise in zwei um 180° zueinander gedrehten Stellungen an den Seitenwänden anbringbar sind, so daß die Anschlußschrauben entweder von der Vorderseite oder von der Rückseite des Gehäuses her betätigbar sind, und daß die Festkontakt­schienen mit ihren aus den Seitenwänden des Ge­häuses hervorstehenden Enden in die Gehäuseböck­chen hineinragen.The task is solved, starting from the switching device described at the beginning, in that the connection screws are accommodated in separate housing blocks, which can be attached in two positions rotated by 180 ° to one another on the side walls, so that the connection screws either from the front or are operable from the rear of the housing, and that the fixed contact rails protrude into the housing blocks with their ends protruding from the side walls of the housing.

Die Anschlußschrauben 19 befinden sich mit ihrem Schraubenköpfen unterhalb von Bohrungen 16, 17 und 18, deren Durchmesser etwas kleiner gehalten ist als der Durchmesser der Schrauben­köpfe, so daß die Anschlußschrauben nicht aus den Gehäuseböckchen herausragen oder herausfallen können. Wie weiter unten noch näher erläutert wird, wirkt jede Anschlußschraube mit einem im wesentlichen als Rechteckrahmen ausgebildeten Metallkäfig 23 zusammen, der durch die betreffende Anschlußschraube verschiebbar ist. Jedes Gehäuse­böckchen weise drei Öffnungen 20, 21 und 22 zum Hindurchführen der elektrischen Anschlußleitungen auf.The switching device according to FIG. 1 has a housing 1 which is essentially rectangular in cross section, with an upper front side 2, a lower rear side 3 and four side walls 4, 5 and 6, 7 in the figure. In this exemplary embodiment, six fixed contact rails 8, 9, 10, 11, 12 and 13 are provided, which can also be seen in particular from FIGS. 2 to 6. The ends of these fixed contact rails protrude from the two side walls 4 and 5 of the housing. The connecting screws 19, which are used to clamp the electrical connecting lines (not shown) to the fixed contact rails, are accommodated in separate housing blocks 14 and 15. The number of connection screws 19 corresponds to the number of fixed contact rails, so there are a total of six connection screws in the present case, namely three connection screws in the housing block 14 and a further three in the housing block 15. The connection screws 19 are located with their screw heads below the holes 16 , 17 and 18, the diameter of which is somewhat smaller is held as the diameter of the screw heads, so that the connecting screws do not protrude from the housing block or fall out. As will be explained in more detail below, each connection screw interacts with a metal cage 23 which is essentially designed as a rectangular frame and can be displaced by the connection screw in question. Each housing block has three openings 20, 21 and 22 for the passage of the electrical connecting lines.

Wesentlich an der Gestaltung der Gehäuseböckchen ist nun, daß diese wahlweise in zwei um 180° zu­einander gedrehten Stellungen an den beiden Seitenwänden 4 bzw. 5 des Gehäuses 1 anbringbar sind, so daß die Anschlußschrauben 19 entweder von der Vorderseite 2, wie bei den eingezeichneten Gehäuseböckchen 14, oder von der Rückseite 3 des Gehäuses her, wie bei dem eingezeichneten Gehäuse­böckchen 15 zu ersehen ist, betätigbar sind. In den Figuren 1 und 2 sind die beiden Gehäuseböck­chen 14 und 15 der Deutlichkeit halber mit Abstand von dem Gehäuse 1 eingezeichnet. In Betriebsstellung liegen sie jedoch dicht an den beiden Seitenwänden 4 bzw. 5 des Gehäuses 1 an, so daß die Enden der Festkontaktschienen 8 bis 13 in die Gehäuseböck­chen 14, 15, und zwar in das Innere des jeweiligen Metallkäfigs 23 hineinragen. In den beiden Seiten­wänden 4 und 5 des Gehäuses 1 sind im Bereich zwischen den drei Festkontaktschienen 8, 9 und 10 sowie entsprechend auf der gegenüberliegenden Seitenwand 5 je zwei Schlitze 30, 33 und 34, 35 vorgesehen, die einen mittleren schmalen Bereich und beiderseits, das heißt gemäß Figur 1 nach oben und nach unten hin verbreiterte Bereiche 31 und 32 mit abgerundeten Enden aufweisen. Jedes Gehäuseböckchen 14 bzw. 15 weist zwei haupt­zylindrische Vorsprünge 24, 25 auf, die in die verbreiterten Bereiche 31 bzw. 32 einschiebbar sind, und zwar in die oberen verbreiterten Be­reiche 31 dann, wenn die Anschlußschrauben von der Vorderseite 2 her, das heißt im Bild der Figur 1 von oben her betätigbar sein sollen, oder nach Umdrehen des Gehäuseböckchens um 180° durch Einschieben in die unteren verbreiterten Bereiche 32. Auf einer Seite jedes Vorsprunges 24, 25 ist ein Ansatz 26 bzw. 27 mit beiderseitigen hinterschnittenen Führungsrillen 28 bzw. 29 vorge­sehen, der nach Verschieben des jeweiligen Ge­häuseböckchens hinter die Ränder des schmalen Bereiches des jeweiligen Schlitzes greift. Die verschiedenen Stellungen sind auch aus den Figuren 9 bis 13 ersichtlich.It is essential to the design of the housing lugs that these can be attached either in two positions rotated by 180 ° to one another on the two side walls 4 or 5 of the housing 1, so that the connecting screws 19 either from the front 2, as in the housing lugs shown 14, or from the rear 3 of the housing, as can be seen in the housing block 15 shown, can be actuated. In Figures 1 and 2, the two housing lugs 14 and 15 are drawn at a distance from the housing 1 for the sake of clarity. In the operating position, however, they lie close to the two side walls 4 and 5 of the housing 1, so that the ends of the fixed contact rails 8 to 13 protrude into the housing blocks 14, 15, specifically into the interior of the respective metal cage 23. In the two side walls 4 and 5 of the housing 1, two slots 30, 33 and 34, 35 are provided in the area between the three fixed contact rails 8, 9 and 10 and correspondingly on the opposite side wall 5, which have a medium narrow area and on both sides, that 1 means regions 31 widened upwards and downwards according to FIG and 32 have rounded ends. Each housing block 14 and 15 has two main cylindrical projections 24, 25 which can be inserted into the widened areas 31 and 32, respectively, in the upper widened areas 31 when the connecting screws from the front 2, that is in the picture 1 should be operable from above, or after turning the housing block through 180 ° by pushing it into the lower widened areas 32. On one side of each projection 24, 25 there is an extension 26 and 27 with undercut guide grooves 28 and 29 on both sides provided that, after moving the respective lugs, reaches behind the edges of the narrow area of the respective slot. The various positions can also be seen in FIGS. 9 to 13.

An den beiden weiteren Seitenwänden 6 und 7 des Gehäuses 1 können Hilfskontaktböckchen 39 ange­bracht werden, und zwar ebenfalls wahlweise in zwei um 180° zueinandergedrehten Stellungen, so daß die Anschlußschrauben 42 entweder von der Vorderseite 2, das heißt im Bild der Figur 1 von oben her oder von der Rückseite 3 des Gehäuses her betätigbar sind. Die beiden Seitenwände 6 und 7 des Gehäuses 1, an welchen die Hilfskontakt­böckchen 39 anbringbar sind, weisen je einen nach Figur 1 vertikalen Schlitz 36 bzw. eine recht­eckige Öffnung auf. Wie weiter unten noch näher ausgeführt wird, befindet sich auf der Innenseite dieses Schlitzes ein Kontaktbrückenhalter 37, der eine Ausnehmung 38 besitzt. Wie die Figur 1 und die Figuren 3, 5 und 18 veranschaulichen, ist in dem Hilfskontaktböckchen 39 ein Hilfskontakt­ brückenhalter 81 vorgesehen, der mit einem Vorsprung 40 ausgestatttet ist. Wenn das Hilfs­kontaktböckchen 39 in der gewählten Stellung an der betreffenden Seitenwand 6 bzw. 7 anliegt und zum Beispiel durch Schrauben befestigt ist, ragt der Vorsprung 40 durch den Schlitz 36 hin­durch und greift formschlüssig in die Ausnehmung 38 ein.Auxiliary contact blocks 39 can be attached to the two further side walls 6 and 7 of the housing 1, and likewise optionally in two positions rotated by 180 °, so that the connecting screws 42 either from the front 2, that is to say in the image of FIG. 1, from above or can be actuated from the rear 3 of the housing. The two side walls 6 and 7 of the housing 1, to which the auxiliary contact blocks 39 can be attached, each have a vertical slot 36 or a rectangular opening as shown in FIG. 1. As will be explained in more detail below, there is a contact bridge holder 37 on the inside of this slot, which has a recess 38. As FIG. 1 and FIGS. 3, 5 and 18 illustrate, there is an auxiliary contact in the auxiliary contact block 39 bridge holder 81 is provided, which is equipped with a projection 40. If the auxiliary contact lug 39 is in the selected position on the relevant side wall 6 or 7 and is fastened, for example, by screws, the projection 40 projects through the slot 36 and engages in a form-fitting manner in the recess 38.

Damit das Hilfskontaktböckchen 39 wahlweise in der einen oder anderen Stellung, wie oben be­schrieben wurde, angebracht werden kann und die Schaltfunktion, nämlich Einschalten und Aus­schalten unverändert bleibt, weist der Hilfs­kontaktbrückenhalter 81 zwei Kontaktbrücken 82 und 83 auf, die zu beiden Seiten von mittig ange­ordneten Festkontaktschienen 79 und 80 verschieb­bar sind. Die Hilfskontaktbrücken sind mittels Druckfedern in dem Hilfskontaktbrückenhalter gehalten. Je nach Wahl der Stellung am Gehäuse 1 verschiebt sich der Hilfskontaktbrückenhalter 81 zum Einschalten entweder bei der Betrachtung der Figur 18 nach oben hin oder nach unten hin, so daß entweder die Kontaktbrücke 83 oder die Kontaktbrücke 82 den Einschaltvorgang vollzieht. Bei dem Ver­schiebevorgang wird der Hilfskontaktbrückenhalter 81 durch nicht gezeichnete Rippen und durch die Führungsteile 84 und 85 geführt. Die äußeren Enden der Festkontaktschienen 79 und 80 sind mit je einem Metallkäfig 78 verbunden, in denen die An­schlußschrauben 42 sitzen. An den benachbarten Stirnflächen des Hilfskontaktböckchen sind Durch­brechungen bzw. Öffnungen 43 (Figur 1) zum Ein­führen von Anschlußleitungen vorgesehen. Wie ins­besondere die Figur 8 zeigt, sind die Hilfskontakt­böckchen 39 so breit ausgebildet, daß die Stirn­ flächen, an denen sich die Öffnungen 43 befinden, mit den Außenflächen der Gehäuseböckchen 14 und 15 fluchten. Die Anschlußschrauben 19 und 42 sowie die Durchbrechungen bzw. Öffnungen 20, 21, 22 und 43 liegen auf beiden Seiten des Gehäuses in Reihe zueinander. Wenn das Hilfskontaktböck­chen 39 auf der Innenseite, wie Figur 1 zeigt, durch einen Deckel verschlossen ist, versteht es sich, daß hier ebenfalls ein Schlitz 41 ent­sprechend dem beschriebenen Schlitz 36 vorzu­sehen ist, so daß der Vorsprung 40 wie beschrieben hindurchragen kann.So that the auxiliary contact block 39 can be attached in one or the other position, as described above, and the switching function, namely switching on and switching off, remains unchanged, the auxiliary contact bridge holder 81 has two contact bridges 82 and 83, which are arranged on both sides of centrally arranged fixed contact rails 79 and 80 are slidable. The auxiliary contact bridges are held in the auxiliary contact bridge holder by means of compression springs. Depending on the selection of the position on the housing 1, the auxiliary contact bridge holder 81 moves to switch on either when viewing FIG. 18 upwards or downwards, so that either the contact bridge 83 or the contact bridge 82 carries out the switch-on process. During the displacement process, the auxiliary contact bridge holder 81 is guided through ribs (not shown) and through the guide parts 84 and 85. The outer ends of the fixed contact rails 79 and 80 are each connected to a metal cage 78 in which the connection screws 42 are seated. Openings or openings 43 (FIG. 1) for introducing connecting lines are provided on the adjacent end faces of the auxiliary contact block. As FIG. 8 in particular shows, the auxiliary contact blocks 39 are so wide that the forehead surfaces on which the openings 43 are aligned with the outer surfaces of the housing blocks 14 and 15. The connecting screws 19 and 42 and the openings or openings 20, 21, 22 and 43 are in series with one another on both sides of the housing. If the auxiliary contact block 39 on the inside, as shown in FIG. 1, is closed by a cover, it goes without saying that a slot 41 corresponding to the slot 36 described must also be provided here, so that the projection 40 can protrude as described.

Insbesondere die Figuren 3 und 5 veranschaulichen, daß drei Hauptkontaktbrücken 60, 61 und 62 in einem gemeinsamen Kontaktbrückenhalter 37 angeordnet sind, und zwar unter Federdruck in rechteckigen Fenstern 57, 58 und 59. Der Betätigungsvorsatz, welcher bei dem dargestellten Auführungsbeispiel einen Drehgriff 44 aufweist, ist grundsätzlich derart ausgebildet, daß der Kontaktbrückenhalter 37 senkrecht zur Vorder- und Rückseite des Gehäuses zwischen den beiden Schaltstellungen, nämlich Aus-Stellung nach Figur 3 und Ein-Stellung nach Figur 5, bewegbar ist.FIGS. 3 and 5 in particular illustrate that three main contact bridges 60, 61 and 62 are arranged in a common contact bridge holder 37, namely under spring pressure in rectangular windows 57, 58 and 59. The actuating attachment, which in the exemplary embodiment shown has a rotary handle 44, is basically designed such that the contact bridge holder 37 is movable perpendicular to the front and back of the housing between the two switching positions, namely the off position according to FIG. 3 and the on position according to FIG. 5.

Gemäß dem dargestellten Ausführungsbeispiel weist der Betätigungsvorsatz einen Drehgriff 44 auf, der entsprechend den Schaltstellungen um eine senkrecht zur Vorderseite 2 des Gehäuses 1 ver­laufende Achse 45 drehbar ist. Die Achse 45 ist durch ein Rastvorrichtung 46 hindurchgeführt und greift in ein zylindrisches Bauelement 52 ein. Das zylindrische Bauelement weist zwei Schrauben­windungen 53 und 54 auf, die formschlüssig mit Teilen des Kontaktbrückenhalters 37 zusammen­ wirken. Vorteilhafterweise sind die Schrauben­windungen als Rillen ausgebildet, in welche Vor­sprünge 63 und 64 des Kontaktbrückenhalters 37 eingreifen. Durch Drehen des Drehgriffs 44 und damit der Achse 45 wird auf diese Weise der Kon­taktbrückenhalter 37 aufwärts oder abwärts be­wegt. Wie die Figuren 3 und 5 veranschaulichen, ist der Kontaktbrückenhalter 37 im wesentlichen U-förmig ausgebildet. Der Abstand und die Länge der beiden Schenkel 55 und 56 des Kontaktbrücken­halters sind so gewählt, daß das zylindrische Bauelement 52 in einer Schaltstellung, nämlich in der Einschaltstellung, in der Ausnehmung zwischen den beiden Schenkeln 55 und 56 sitzt. Diese Schaltstellung ist in Figur 5 dargestellt. Die Vorsprünge 63 und 64 sind gemäß Figur 3 an den Enden der Schnekel 55, 56 vorgesehen und verlaufen radial nach innen, so daß sie in die Rillen 53, 54 eingreifen können.According to the exemplary embodiment shown, the actuating attachment has a rotary handle 44 which, according to the switching positions, can be rotated about an axis 45 running perpendicular to the front side 2 of the housing 1. The axis 45 is passed through a latching device 46 and engages in a cylindrical component 52. The cylindrical component has two screw turns 53 and 54, which form-fit together with parts of the contact bridge holder 37 Act. The screw turns are advantageously designed as grooves, into which projections 63 and 64 of the contact bridge holder 37 engage. By turning the rotary handle 44 and thus the axis 45, the contact bridge holder 37 is moved up or down in this way. As FIGS. 3 and 5 illustrate, the contact bridge holder 37 is essentially U-shaped. The distance and the length of the two legs 55 and 56 of the contact bridge holder are selected so that the cylindrical component 52 sits in a switch position, namely in the switch-on position, in the recess between the two legs 55 and 56. This switch position is shown in Figure 5. The projections 63 and 64 are provided according to FIG. 3 at the ends of the snails 55, 56 and extend radially inwards so that they can engage in the grooves 53, 54.

Wie inbesondere Figur 19 veranschaulicht, weist die Rastvorrichtung 46 einen zentralen Drehkörper 47 auf, der mit vier auf dem Umfang gleichmäßig verteilten Einbuchtungen 90 versehen ist. Zu diesem Drehkörper 47 sind zwei einander gegen­überliegende Schieber 48 und 49 angeordnet, die mit je einem Vorsprung 91 in die Einbuchtungen 90 eingreifen. Jeder Schieber 48, 49 steht unter dem Druck von zwei nebeneinander vorgesehenen Druckfedern 50, 51. Ferner sind die Schieber zwischen je zwei in das Gehäuse 1 hineinra­genden parallen Führungen 87 und 88 gleitend geführt. Das zylindrische Bauelement 52 und der Drehkörper 47 der Rastvorrichtung 46 sind zweck­mäßigerweise einstückig ausgebildet und sie weisen ein im Querschnitt quadratisches Loch mit einer abgeschrägten Kante 89 auf. Entsprechend ist der Querschnitt der Achse 45 des Drehgriffs im Bereich des Lochs angepaßt. Es sind ferner nicht gezeichnete Anschläge vorgesehen,die nur ein Drehen des Drehgriffs 44 zwischen den beiden Schaltstellungen gestatten. Die Rastvorrichtung 46 dient im wesentlichen dazu, daß die Schalt­vorgänge schnell ausgeführt werden und daß der Kontaktbrückenhalter 37 und damit die jeweiligen Kontakte sicher in der jeweiligen Schaltstellung gehalten werden.As illustrated in particular in FIG. 19, the latching device 46 has a central rotating body 47 which is provided with four indentations 90 which are evenly distributed over the circumference. To this rotating body 47, two opposing sliders 48 and 49 are arranged, each of which engages in the indentations 90 with a projection 91. Each slide 48, 49 is under the pressure of two compression springs 50, 51 provided next to one another. Furthermore, the slide is slidably guided between two parallel guides 87 and 88 protruding into the housing 1. The cylindrical component 52 and the rotating body 47 of the latching device 46 are expediently formed in one piece and they have a square hole in cross section with a bevelled edge 89. The cross section of the axis 45 of the rotary handle in the region of the hole is adapted accordingly. There are also stops not shown, which only allow turning of the rotary handle 44 between the two switching positions. The latching device 46 essentially serves to ensure that the switching operations are carried out quickly and that the contact bridge holder 37 and thus the respective contacts are held securely in the respective switching position.

Wie die Figuren 2 und 7 noch veranschaulichen, sitzt auf der Achse 45 etwa im Bereich zwischen der Rastvorrichtung 46 und dem Drehgriff 44 ein Hohlzylinder 65 mit einer zylindrischen Bohrung. In diesem Bereich ist auf die Achse 45 zylindrisch ausgebildet. Mit dem Hohlzylinder arbeitet ein im wesentlichen U-förmiger Federbügel 66 zu­sammen, dessen Schenkel 67 und 68 in zwei Kerben 69 des Hohlzylinders 65 eingreifen können. Diese Vorrichtung dient zur Montageerleichterung.As FIGS. 2 and 7 also illustrate, a hollow cylinder 65 with a cylindrical bore sits on the axis 45 approximately in the area between the latching device 46 and the turning handle 44. In this area, the axis 45 is cylindrical. An essentially U-shaped spring clip 66 cooperates with the hollow cylinder, the legs 67 and 68 of which can engage in two notches 69 of the hollow cylinder 65. This device serves to facilitate assembly.

Es wurde bereits weiter oben angedeutet, daß das Gehäuseböckchen 14 bzw. 15 an einer parallel zu der Vorderseite 2 und Rückseite 3 des Gehäuses 1 verlaufenden Stirnwand mit drei Bohrungen 16, 17 und 18 versehen ist, unter welchen gemäß Figur 14 die Anschlußschrauben drehbar gehalten sind. Um ein Verschieben der Schrauben zu vermeiden, greifen Stege 71 und 72 hinter die Schraubenköpfe. Jede Anschlußschraube ist in einem Gewinde eines rechteckigen Metallkäfigs 23 einschraubbar, so daß der Metallkäfig in Klemmstellung zu der Festkontaktschiene 8 bis 13 und der Anschluß­leitung verschiebbar ist. Die Metallkäfige 23 sind vorteilhafterweise durch Rippen 70 von­einander getrennt und an diesen Rippen geführt. Entsprechende Rippen 86 können auch in den Hilfs­kontaktböckchen gemäß Figur 18 vorgesehen sein. Wie aus Figur 8 zu ersehen ist, sind die Gehäuse­böckchen 14 und 15 vorteilhafterweise an die Breite des Gehäuses 1 angepaßt.It has already been indicated above that the housing block 14 or 15 is provided on an end wall running parallel to the front 2 and rear 3 of the housing 1 with three bores 16, 17 and 18, under which, according to FIG. 14, the connecting screws are rotatably held . To prevent the screws from moving, bars 71 and 72 reach behind the screw heads. Each connecting screw can be screwed into a thread of a rectangular metal cage 23, so that the metal cage is in the clamping position Fixed contact rail 8 to 13 and the connecting line is displaceable. The metal cages 23 are advantageously separated from one another by ribs 70 and guided on these ribs. Corresponding ribs 86 can also be provided in the auxiliary contact blocks according to FIG. 18. As can be seen from FIG. 8, the housing blocks 14 and 15 are advantageously adapted to the width of the housing 1.

Die Figuren 15 bis 17 zeigen noch einige kon­strucktive Einzelheiten, so die Druckfeder 73, die die Hauptkontaktbrücke 61 in einem Fenster des Kontaktbrückenhalters 37 hält. Ferner ist die formschlüssige Halterung z.B. der Festkon­taktschienen 9 und 12 dargestellt. Von oben werden diese jeweils von Rippen 74 in Stellung gehalten. Um eine Verschiebung der Hauptkontakt­schienen in Längsrichtung zu vermeiden, sind diese mit Verbreiterungen 75 versehen, die zwischen weiteren Rippen 76 und Anschlägen 77 gehalten sind. Um die Festkontaktschienen leichter montieren zu können, ist es vorteilhaft, das Gehäuse 1 etwa im Niveau der Festkontaktschienen zu teilen, was durch die Bezugszeichen 4a, 4b und 5a, 5b und auch durch die Darstellungsweise der Figuren 12 und 13 angedeutet ist.FIGS. 15 to 17 also show some constituent details, such as the compression spring 73, which holds the main contact bridge 61 in a window of the contact bridge holder 37. Furthermore, the form-fitting holder is e.g. the fixed contact rails 9 and 12 shown. From above, these are held in position by ribs 74. In order to avoid a displacement of the main contact rails in the longitudinal direction, they are provided with widenings 75 which are held between further ribs 76 and stops 77. In order to be able to mount the fixed contact rails more easily, it is advantageous to divide the housing 1 approximately at the level of the fixed contact rails, which is indicated by the reference numerals 4a, 4b and 5a, 5b and also by the manner of representation of FIGS. 12 and 13.
