Abstract

A fused switch unit (1) is provided with a housing (2) in which a fuse plug (10) is arranged such that it can pivot to and fro between a switched-off position and a switched-on position. The fuse plug (10) has a grip part (11) and a retaining area (12) for a fuse link (20) and is capable of being pushed into the fused switch unit (1) as far as an operating position. Both the fused switch unit (1) and/or associated components (2, 30) as well as the grip part (11) of the fuse plug (10) each have a through-opening (15, 35). The through-openings (15, 35) are positioned such that they essentially do not overlap when the fuse plug (10) is in its operating position, and such that they are at least partially aligned with one another in order to hold an interlocking element (40) when the fuse plug (10) is in a position in which it is partially withdrawn from its operating position in the fused switch unit (1).

Description

Die Erfindung bezieht sich auf eine Schaltersicherungseinheit gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a circuit breaker unit according to the preamble of claim 1.

Derartige Schaltersicherungseinheiten sowie die in solchen Schaltersicherungseinheiten verwendeten Sicherungsstöpsel und Schaltwippen werden in mannigfaltigen Ausführungen in Gebäuden, sowohl in privaten als auch gewerblichen Gebäuden, insbesondere in Gebäuden, in denen Maschinen elektrisch betrieben werden, eingesetzt. Es ist ferner möglich, solche Schaltersicherungseinheiten bzw. Bauteile, z.B. die Schaltwippe, oder den Sicherungsstöpsel direkt für die elektrische Absicherung von elektrisch betriebenen Maschinen an oder in Maschinenelementen oder -gehäusen einzusetzen.Such switch fuse units and those in such Switch fuse units used fuse plugs and Shift paddles are available in various designs in buildings, in both private and commercial buildings, in particular in buildings where machines are operated electrically be used. It is also possible to use such switch fuse units or components, e.g. the rocker switch, or the fuse plug directly for electrical protection of electrically operated machines on or in machine elements insert or housing.

Eine Schaltersicherungseinheit mit Schaltwippe und Sicherungseinsatz ist z.B. aus der DE 34 06 815 C2 bekannt. Solche Schaltersicherungseinheiten dienen dazu, den Stromkreis und damit die elektrische Versorgung von Maschinen und Geräten automatisch zu unterbrechen, wenn die Stromstärke bzw. die Leistung in dem Stromkreis einen bestimmten festgesetzten Wert überschreiten. Um diese Werte den Gegebenheiten, insbesondere den elektrischen Maschinen und Geräten bzw. externen Vorgaben, z.B. Sicherheitsvorgaben, anzupassen, können in die Schaltersicherungseinheiten bzw. in den Sicherungsstöpsel Sicherungseinsätze eingesetzt werden, die unterschiedliche Kennwerte aufweisen. A switch fuse unit with rocker switch and fuse link is e.g. known from DE 34 06 815 C2. Such Switch fuse units serve the circuit and thus the electrical supply of machines and devices automatically interrupt when the current or the Power in the circuit a certain fixed value exceed. To take these values into account, in particular the electrical machines and devices or external specifications, e.g. Security requirements, can be adjusted in the switch fuse units or fuse inserts in the fuse plugs are used, the different parameters exhibit.

Solche Schaltersicherungseinheiten werden insbesondere auch dazu verwendet, den Stromkreis, insbesondere bei notwendigen Reparaturen an den elektrischen Geräten und Maschinen, manuell zuverlässig zu unterbrechen. Dazu werden die Schaltwippe oder der Sicherungsstöpsel mit dem entsprechenden Sicherungseinsatz, die zwischen einer Einschaltstellung und einer Ausschaltstellung schwenkbar in einem Gehäuse der Schaltersicherungseinheit gelagert sind, in ihre Ausschaltstellung bewegt. Der Stromkreis wird dadurch unterbrochen, so daß insbesondere Reparaturen an elektrisch betriebenen Maschinen und Geräten gefahrlos durchgeführt werden können.Such switch fuse units are in particular also used the circuit, especially when necessary Repairs to electrical equipment and machines, manually to reliably interrupt. For this, the rocker switch or the fuse plug with the corresponding fuse insert, between an on position and an off position pivotable in a housing of the switch fuse unit are stored in their off position emotional. The circuit is interrupted, so that in particular Repairs to electrically operated machines and Devices can be carried out safely.

Es besteht jedoch die Gefahr, daß die Schaltwippe oder der Sicherungsstöpsel ungewollt von ihrer Ausschaltstellung in die Einschaltstellung bewegt werden, sei es z.B. dadurch, daß die Elemente ungenau eingestellt worden sind und sich in einer Zwischenstellung befinden, aus der sie wieder in die Einschaltstellung zurückfallen, oder sei es durch eine dritte Person, die aus Versehen an die Vorrichtung stößt oder sie bewußt in die Einschaltstellung bewegt, weil sie nicht über die möglicherweise noch stattfindenden Reparaturen und eine mögliche Gefährdung informiert ist.However, there is a risk that the rocker switch or Safety plug unintentionally from its switch-off position in the Switch-on position, e.g. in that the Elements have been set inaccurately and are in one Intermediate position, from which they are back in the on position fall behind, or be it by a third Person who accidentally bumps into the device or it deliberately moved to the on position because it doesn't have the repairs that may still take place and a potential danger is informed.

Es ist daher eine Aufgabe der Erfindung, eine Schaltersicherungseinheit zur Verfügung zu stellen, die einfach und zuverlässig eine Sicherung des Schaltstöpsels in seiner Ausschaltstellung ermöglicht. Insbesondere sollen dabei übliche, nicht auf eine bestimmte Schaltersicherungseinheit abgestimmte Vorrichtungen, vor allem auch standardübliche Verriegelungsvorrichtungen, die in keinerlei Zusammenhang mit einer Schaltersicherungseinheit stehen, eingesetzt werden können.It is therefore an object of the invention to provide a circuit breaker unit to provide that simple and reliably secure the switch plug in its off position allows. In particular, customary not matched to a specific switch fuse unit Devices, especially standard locking devices, that has no connection with any Switch fuse unit stand, can be used.

Diese Aufgabe wird durch eine Schaltersicherungseinheit nach Anspruch 1 gelöst. Die Ansprüche 2 bis 10 beschreiben vorteilhafte Ausführungsformen der erfindungsgemäßen Schaltersicherungsheinheit. This task is performed by a circuit breaker unit Claim 1 solved. Claims 2 to 10 describe advantageous Embodiments of the switch fuse unit according to the invention.

Für eine Sicherung des Sicherungsstöpsels in seiner Ausschaltstellung wird der Sicherungsstöpsel aus seiner Arbeitsposition aus der Schaltersicherungseinheit zurückgezogen, bis die Durchgangsöffnung des Sicherungsstöpsels soweit mit der Durchgangsöffnung der Schaltersicherungseinheit oder eines Bauteils derselben fluchtet bzw. die beiden Durchgangsöffnungen sich so weit überlappen, daß eine Verriegelungsvorrichtung, z.B. ein standardübliches Hängeschloß oder ein Plombendraht, durch die beiden Durchgangsöffnungen eingeführt werden kann.For securing the fuse plug in its off position the safety plug is removed from its working position withdrawn from the switch fuse unit until the Through opening of the safety plug so far with the through opening the switch fuse unit or a component the same is aligned or the two through openings are so overlap far that a locking device, e.g. on standard padlock or a sealing wire through which two through openings can be inserted.

Ein Herausziehen des Sicherungsstöpsels aus seiner Arbeitsposition ist nur in der Ausschaltstellung möglich, da der Sicherungsstöpsel ansonsten durch Gehäuseteile der Schaltersicherungseinheit in seiner Arbeitsposition gehalten wird.Pulling the safety plug out of its working position is only possible in the off position because the Fuse plugs otherwise through housing parts of the switch fuse unit is held in its working position.

Unter "Arbeitsposition" des Sicherungsstöpsels ist die Position zu verstehen, in der der Sicherungsstöpsel noch zwischen seiner Einschaltstellung und seiner Ausschaltstellung, ggf. in der Schaltwippe, geschwenkt werden kann. Der Sicherungsstöpsel befindet sich dann nicht mehr in seiner Arbeitsposition, wenn er soweit aus der Schaltersicherungseinheit oder der Schaltwippe herausgezogen ist, daß ein Schwenken in seine Einschaltstellung nicht mehr möglich ist, weil Teilbereiche des Sicherungsstöpsels gegen Gehäuseteile der Schaltersicherungseinheit stoßen.The position is under the "working position" of the safety plug to understand in which the fuse plug is still between its switch-on position and its switch-off position, if necessary in the rocker switch can be pivoted. The safety plug is no longer in his working position if so far from the switch fuse unit or the rocker switch is pulled out that a pivot in its on position is no longer possible because part of the fuse plug against housing parts of the switch fuse unit bump.

Gemäß der Erfindung ist es daher möglich, standardübliche Verriegelungsvorrichtungen, wie z.B. übliche Vorhängeschlösser oder Plombendrähte o.dergl., zur Verriegelung zu verwenden. Speziell hergestellte Verriegelungsvorrichtungen, die nur für ausgewählte Schaltersicherungseinheiten passen, sind nicht erforderlich. Es ist daher nicht notwendig, unterschiedliche Verriegelungsvorrichtungen für unterschiedliche Schaltersicherungseinheiten zu bevorraten. Dies ist auch für den Privatbereich hilfreich, weil der nicht gewerbliche Nutzer normalerweise nicht über spezielle Verriegelungsvorrichtungen verfügt.According to the invention it is therefore possible to use standard locking devices, such as. usual padlocks or lead wires or the like to use for locking. Specially manufactured locking devices that are only for selected switch fuse units do not fit required. It is therefore not necessary to have different ones Locking devices for different switch fuse units to stock up. This is also for the private sector helpful because the non-commercial user usually does not have special locking devices.

Ein Umlegen in die Einschaltstellung wird zuverlässig ausgeschlossen, weil der Sicherungsstöpsel zum Anbringen einer Verriegelungsvorrichtung aus seiner Endposition herausgezogen werden muß und dann Teile bzw. Bereiche des Sicherungsstöpels gegen das Gehäuse der Schaltersicherungseinheit stoßen würden. Die Verriegelungsvorrichtung sichert demnach eine longitudinale, aus der Arbeitsposition heraus verschobene Position des Sicherungsstöpsels in der Schaltersicherungseinheit.Switching to the switch-on position is reliably excluded, because the safety plug for attaching a locking device be pulled out of its end position must and then parts or areas of the fuse plug would hit the housing of the switch fuse unit. The locking device accordingly secures a longitudinal, position of the Fuse plug in the switch fuse unit.

Bevorzugt weisen die Durchgangsöffnungen in dem Sicherungsstöpsel sowie in der Schaltersicherungseinheit oder deren Bauteilen (z.B. der Schaltwippe) einen im wesentlichen kongruenten Querschnitt auf. Dadurch wird ein vollständiges Überlappen der beiden Durchgangsöffnungen und damit ein problemloses Einführen einer Verriegelungsvorrichtung durch die Durchgangslöcher erreicht. Es ist ferner möglich, Verriegelungsvorrichtungen zu verwenden, deren Querschnittsabmessungen einem identischen Querschnitt beider Durchgangsöffnungen angepaßt sind, so daß kein axiales Spiel zwischen Sicherungsstöpsel und Schaltersicherungseinheit möglich ist, sobald eine derartige Verriegelungsvorrichtung eingeführt ist.The through openings preferably have in the securing plug as well as in the switch fuse unit or its Components (e.g. the rocker switch) are essentially congruent Cross section on. This will completely overlap of the two through openings and thus a problem-free Insert a locking device through the through holes reached. It is also possible to use locking devices to use, the cross-sectional dimensions of a adapted identical cross-section of both through openings are, so that no axial play between fuse plug and Switch fuse unit is possible as soon as such Locking device is inserted.

Bei einer Ausführungsform ist die Durchgangsöffnung in dem Sicherungsstöpsel geringfügig kleiner als die Durchgangsöffnung in der Schaltersicherungseinheit oder der Schaltwippe. Da der Sicherungsstöpsel in die Schaltersicherungseinheit bzw in die Schaltwippe eingeführt wird, ist ein gewisses Spiel des Sicherungsstöpsels in der Schaltersicherungseinheit aus produktionstechnischen Gründen und auch um eine zu starke Reibung und dadurch einen Verschleiß zu vermeiden, unumgänglich. Leichte Positionsschwankungen in einer von der Einschubrichtung abweichenden Richtung sind daher die Folge. Ein geringfügig kleineres Loch in dem Sicherungsstöpsel führt daher dazu, daß auch bei einer möglichen, durch Spiel hervorgerufenen Auslenkung des Sicherungsstöpsels in einer von der Einschubrichtung abweichenden Richtung immer ein vollständiges Überlappen der Durchgangsöffnung in dem Sicherungsstöpsel mit der Durchgangsöffnung in der Schaltersicherungseinheit möglich ist.In one embodiment, the through opening is in the Safety plug slightly smaller than the through opening in the switch fuse unit or the rocker switch. There the fuse plug in the switch fuse unit or in the rocker switch is inserted is a certain game of Fuse plug in the switch fuse unit from production technology Foundations and too much friction and thus avoid wear and tear. Slight position fluctuations in one direction of insertion deviating directions are therefore the result. A little smaller hole in the fuse plug therefore leads to that even with a possible game-induced Deflection of the safety plug in one of the insertion direction deviating direction always a complete overlap the through opening in the safety plug with the Through opening possible in the switch fuse unit is.

Vorteilhaft ist es ferner, Einführhilfen vorzusehen, indem die Durchgangsöffnungen des Sicherungsstöpsels und/oder der Schaltersicherungseinheit nach außen erweitert sind.It is also advantageous to provide insertion aids by the Through openings of the fuse plug and / or the switch fuse unit are expanded to the outside.

Bei einer bevorzugten Ausführungsform überlappen sich die Durchgangsöffnungen des Sicherungsstöpsels und der Schaltersicherungseinheit nicht oder nur sehr geringfügig, wenn sich der Sicherungsstöpsel in seiner Arbeitsposition befindet. Dadurch wird vermieden, daß als Verriegelungsvorrichtung sehr klein dimensionierte Gegenstände verwendet werden können, die bereits durch eine möglicherweise vorhandene Überlappung der beiden Durchgangsöffnungen, z.B. hervorgerufen durch Herstellungstoleranzen, eingeführt werden können, wenn der Sicherungsstöpsel sich noch in seiner Arbeitsposition befindet.In a preferred embodiment, the overlap Through openings of the fuse plug and the switch fuse unit not or only very slightly if the Safety plug is in its working position. Thereby is avoided that as a locking device very small dimensioned objects can be used that already due to a possible overlap of the two through openings, e.g. caused by manufacturing tolerances, can be inserted when the fuse plug is still in its working position.

Bevorzugt weist ein Sicherungsstöpsel einen Haltebereich auf, der an einem Gehäuse, insbesondere an einer Positoniervorrichtung des Gehäuses, anliegt, sobald die Öffnungen fluchten oder sich wenigstens teilweise überlappen. Ein solcher Haltebereich ist insbesondere so ausgebildet, daß er mit dem Gehäuse bzw. der Positioniervorrichtung des Gehäuses zusammenwirkt, um den Sicherungsstöpsel bzw. die Schaltwippe in ihrer Ausschaltstellung zuverlässig zu halten. Es ist vorteilhaft, diesen Haltebereich so auszugestalten, daß auch bei einer Vielzahl von Betätigungen und eventuell auftretenden Verschleißerscheinungen, insbesondere Abrieb, eine zuverlässige Haltefunktion erfüllt wird.A securing plug preferably has a holding area, the on a housing, in particular on a positioning device of the housing, as soon as the openings are aligned or at least partially overlap. Such a stopping area is particularly designed so that it with the housing or the positioning device of the housing cooperates to the Safety plug or the rocker switch in its off position to keep reliable. It is beneficial to this Stop area to be designed so that even with a large number of operations and any signs of wear, especially abrasion, a reliable holding function is fulfilled.

Der Haltebereich besteht insbesondere aus einem Teil einer Seitenwand des Aufnahmebereiches für einen Sicherungseinsatz. Zusätzliche konstruktive Maßnahmen werden dadurch vermieden, die Kosten für die Bauteile gering gehalten.The holding area consists in particular of a part of a Side wall of the receiving area for a fuse link. Additional constructive measures are avoided the costs for the components kept low.

Das Gehäuse der Schaltersicherungseinheit umfaßt bevorzugt Anschlagflächen für die Schaltwippe und/oder den Sicherungsstöpsel, an der beide Bauteile in der Einschaltstellung oder der Ausschaltstellung der Schaltwippe anliegen. Diese Anschlagflächen unterstützen eine zuverlässige Positionierung der Schaltwippe oder des Sicherungsstöpsels, so daß auch hierdurch die Gefahr von Fehlstellungen oder -bedienungen verringert wird.The housing of the switch fuse unit preferably comprises Stop surfaces for the rocker switch and / or the safety plug, on both components in the on position or the switch rocker switch is in the off position.

In Fig. 1 ist der strukturelle Aufbau einer Schaltersicherungseinheit 1, einer Schaltwippe 30 und eines Sicherungsstöpsels 10 gemäß der Erfindung deutlich erkennbar.1 shows the structural design of a circuit breaker unit 1, a rocker switch 30 and a fuse plug 10 clearly recognizable according to the invention.

Die Schaltersicherungseinheit 1 umfaßt ein Gehäuse 2, in dem eine Schaltwippe 30 schwenkbar gelagert ist, so daß sie zwischen der in Fig. 1 gezeigten Einschaltstellung und der in Fig. 2 gezeigten Ausschaltstellung schwenkbar ist. In die Schaltwippe 30 ist ein Sicherungsstöpsel 10 eingeschoben, der sich in Fig. 1 in seiner Endposition befindet. In den Sicherungsstöpsel 10 ist ein Sicherungseinsatz 20 eingesetzt, der auf zwei Seiten von Kontaktvorrichtungen 51, 52 kontaktiert ist, um einen Stromkreis zu schließen. Der Sicherungsstöpsel 10 weist ein Griffteil 11 auf, in das eine Durchgangsöffnung 15 eingebracht ist. The switch fuse unit 1 comprises a housing 2 in which a rocker switch 30 is pivotally mounted so that it is between the switch-on position shown in Fig. 1 and in Fig. 2 shown off position is pivotable. In the Switch rocker 30 is a fuse plug 10 inserted is in its end position in Fig. 1. In the fuse plug 10 a fuse link 20 is used, the contacted on two sides by contact devices 51, 52 is to close a circuit. The safety plug 10 has a handle part 11, into which a through opening 15 is introduced.

Die Schaltwippe 30 ist mit einem Betätigungsgriff 31 versehen, in den eine Durchgangsöffnung 35 eingebracht ist. Die Durchgangsöffnung 35 weist auf der dem Sicherungsstöpsel 10 abgewandten Seite eine Einführhilfe 36 auf, die durch eine trichterartige Erweiterung 36 der Durchgangsöffnung 35 verwirklicht ist. Selbstverständlich könnte auch die Durchgangsöffnung 15 an ihrer dem Betätigungsgriff 31 abgekehrten Seite im Sinne einer Einführhilfe erweitert sein.The rocker switch 30 is provided with an operating handle 31, into which a through opening 35 is introduced. The passage opening 35 points to the opposite of the fuse plug 10 Page an insertion aid 36 by a funnel-like Extension 36 of the through opening 35 realized is. Of course, the through opening 15 could also be on the side facing away from the actuating handle 31 in the sense an insertion aid.

Die beiden Durchgangsöffnungen 15 und 35 sind in Einschubrichtung versetzt bzw. im Abstand voneinander positioniert, so daß sie sich nicht überlappen bzw. miteinander fluchten, so daß keine Verriegelungsvorrichtung durch die Durchgangsöffnungen 15, 35 eingeführt werden kann, wenn und solange sich der Sicherungsstöpsel 10 in seiner Arbeitsposition befindet.The two through openings 15 and 35 are in the direction of insertion offset or positioned at a distance from each other so that they do not overlap or are in alignment with one another, so that no locking device through the through openings 15, 35 can be introduced if and as long as the fuse plug 10 is in its working position.

In der hier gezeigten Einschaltstellung liegt der Sicherungsstöpsel 10 bzw. ein Teil des Griffteils 11 des Sicherungsstöpsels 10 an einer Anschlagfläche 5 des Gehäuses 2 an.The fuse plug is in the switch-on position shown here 10 or part of the handle part 11 of the fuse plug 10 on a stop surface 5 of the housing 2.

Die Anschlagfläche 5 ist mit einer Positioniervorrichtung 3 einheitlich ausgebildet. Die Funktion der Positioniervorrichtung 3 wird im Zusammenhang mit Fig. 3 später genauer erklärt.The stop surface 5 is provided with a positioning device 3 uniformly trained. The function of the positioning device 3 will be explained in more detail later in connection with FIG. 3.

Ferner weist das Gehäuse 2 eine weitere Anschlagfläche 4 auf, an der die Schaltwippe 30 bzw. deren Betätigungsgriff 31 anliegen, wenn sich die Schaltwippe 30 in ihrer Ausschaltstellung gemäß Fig. 2 befindet. Es ist deutlich sichtbar, daß die Kontakte 51 und 52 nicht mehr den Sicherungseinsatz 20 kontaktieren und infolgedessen der Stromkreis unterbrochen ist. Sämtliche Bezugszeichen und Teile in Fig. 2 entsprechen den in Fig. 1 gezeigten.Furthermore, the housing 2 has a further stop surface 4, on which the rocker switch 30 or its actuating handle 31 rest, when the rocker switch 30 is in its off position 2 is located. It is clearly visible that the Contacts 51 and 52 no longer contact fuse link 20 and as a result the circuit is broken. All reference numerals and parts in Fig. 2 correspond to those in Fig. 1 shown.

Der Sicherungsstöpsel 10 befindet sich in Fig. 2 weiterhin in seiner Endposition in der Schaltwippe 30, so daß sich die relativen Positionen der beabstandeten Durchgangsöffnung 15 in dem Sicherungsstöpsel 10 und der Durchgangsöffnung 35 in der Schaltwippe 30 nicht verändert haben. Die Schaltwippe 30 kann daher durch Krafteinwirkung gegen den Betätigungsgriff, in Fig. 2 nach rechts, wieder in ihre Einschaltstellung gemäß Fig. 1 bewegt werden; eine Einführung einer Verriegelungsvorrichtung durch die Durchgangsöffnungen 15, 35 ist jedoch aufgrund ihrer nicht vorhandenen Überlappung ausgeschlossen. Die Schaltwippe 30 befindet sich also in einer ungesicherten Ausschaltstellung, wobei die Position lediglich durch eine Federvorrichtung 53 in der Ausschaltstellung gehalten wird. Wie Fig. 2 zeigt, setzt eine Schwenkbewegung in Richtung der Einschaltstellung eine Kompression der Feder 53 und damit eine Kraftanwendung voraus.The safety plug 10 is still in Fig. 2 in its end position in the rocker switch 30, so that the relative positions of the spaced through opening 15 in the safety plug 10 and the through hole 35 in the Shift rocker 30 have not changed. The rocker switch 30 can therefore by applying force against the operating handle, in Fig. 2 to the right, again in its switched-on position Fig. 1 are moved; an introduction of a locking device through the through openings 15, 35, however, is due to excluded their non-existing overlap. The Switch rocker 30 is therefore in an unsecured switch-off position, the position only by a spring device 53 is held in the off position. How Fig. 2 shows, pivots in the direction of the switch-on position a compression of the spring 53 and thus one Force application ahead.

Fig. 3 zeigt die in den Fig. 1 und 2 dargestellte Ausführungsform, wobei sich die Schaltersicherungseinheit 1 in einer gesicherten Ausschaltstellung befindet.3 shows the embodiment shown in FIGS. 1 and 2, the switch fuse unit 1 in one secured switch-off position.

Der Sicherungsstöpsel 10 ist um eine Länge x, die in dieser Ausführungsform ungefähr 7 mm beträgt, aus ihrer Endposition. in Richtung der Einschuböffnung der Schaltwippe 30 aus dieser herausgezogen. Die Durchgangsöffnung 15 des Sicherungsstöpsels 10 fluchtet nun vollständig mit der Durchgangsöffnung 35 der Schaltwippe 30.The fuse plug 10 is by a length x that in this Embodiment is approximately 7 mm from its end position. in the direction of the insertion opening of the rocker switch 30 from this pulled out. The passage opening 15 of the fuse plug 10 is now completely aligned with the through opening 35 in FIG Shift rocker 30.

Die relative Position der Schaltwippe 30 und des Sicherungsstöpsels 10 wird durch eine Verriegelungsvorrichtung, hier ein schematisch dargestelltes, standardübliches Vorhängeschloß 40, das durch beide Durchgangsöffnungen 15 und 35 durchgeführt worden ist, gesichert. Eine Verschiebung des Sicherungsstöpsels 10 in seine Endposition bzw. aus der Schaltwippe 30 heraus, ist somit ausgeschlossen.The relative position of the rocker switch 30 and the fuse plug 10 is a locking device, here a schematically shown, standard padlock 40, that is carried out through both through openings 15 and 35 has been secured. A shift of the fuse plug 10 into its end position or out of the rocker switch 30, is therefore excluded.

Durch die Längsverschiebung des Sicherungsstöpsels 10 aus der Schaltwippe 30 heraus liegt nun ein Haltebereich 13, der durch eine Seitenwand eines Aufnahmebereichs 12 für den Sicherungseinsatz 20 gebildet wird, an der Positioniervorrichtung 3 des Gehäuses 2 an. Infolgedessen kann das System Schaltwippe 30/ Sicherungsstöpsel 10 in Richtung der Einschaltstellung der Schaltwippe 30 nicht verschwenkt werden, so daß der Sicherungsstöpsel 10 außerhalb seiner Endposition und die Schaltwippe 30 in der Ausschaltstellung verriegelt sind.By the longitudinal displacement of the fuse plug 10 from the Shift paddle 30 is now a holding area 13 through a side wall of a receiving area 12 for the fuse link 20 is formed on the positioning device 3 of the Housing 2. As a result, the system rocker switch 30 / Fuse plug 10 in the direction of the on position Switch rocker 30 can not be pivoted, so that the fuse plug 10 outside its end position and the rocker switch 30 are locked in the off position.

Wie deutlich aus Fig. 3 zu ersehen ist, sind an die Verriegelungsvorrichtung 40, hier das Vorhängeschloß, keine besonderen geometrischen oder strukturellen Anforderungen zu stellen. Es muß lediglich eine Größendimension aufweisen, die es erlaubt, die Verriegelungsvorrichtung durch die Durchgangsöffnungen durchzuführen.As can clearly be seen from Fig. 3, are to the locking device 40, here the padlock, no special ones to make geometric or structural requirements. It just have to have a size dimension that allows the locking device through the through openings perform.

Fig. 4 zeigt eine zweite Ausführungsform einer erfindungsgemäßen Schaltersicherungseinheit 1'. Diese Ausführungsform umfaßt keine Schaltwippe, sondern lediglich einen Sicherungsstöpsel 70, an dem ein Führungselement 76 angeordnet ist.Fig. 4 shows a second embodiment of an inventive Switch fuse unit 1 '. This embodiment does not include a rocker switch, but only a safety plug 70, on which a guide element 76 is arranged.

Ansonsten entspricht der Aufbau des Sicherungsstöpsels 70 im wesentlichen dem Aufbau des in der ersten Ausführungsform verwendeten Sicherungsstöpsels 10. Der Sicherungsstöpsel 70 hat ein Griffteil 71 mit einer Durchgangsöffnung 75, einem Aufnahmbereich 72 für den Sicherungseinsatz 20 und einen Haltebereich 73.Otherwise, the structure of the fuse plug 70 corresponds to essentially the structure of that in the first embodiment fuse plug used. 10. The fuse plug 70 has a handle part 71 with a through opening 75, a Receiving area 72 for the fuse link 20 and a holding area 73rd

Das Führungselement 76 ist seitlich in der Nähe des Griffteils 71 des Sicherungsstöpsels 70 befestigt. Das Führungselement 76 wird innerhalb des Gehäuses 72 der Schaltersicherungseinheit 1' geführt. Es weist ein Rastelement 79 auf, das mit (sehr schematisch dargestellten) Rastelementen 78 der Schaltersicherungseinheit in der Einschalt- und der Ausschaltstellung des Sicherungsstöpsels 70 in Eingriff steht, so daß gerasterte Endstellungen verwirklicht werden.The guide element 76 is laterally close to the handle part 71 of the fuse plug 70 attached. The guide element 76 is inside the housing 72 of the switch fuse unit 1 'led. It has a locking element 79, which (very schematically shown) locking elements 78 of the circuit breaker unit in the on and off position of the Fuse plug 70 is engaged so that rasterized End positions are realized.

Das Führungselement 76 hat ferner eine Blockieröffnung 80, in die ein Blockierriegel 62 einer Schalt- und Blockiervorrichtung 60 eingreift, wenn die Schalt- und Blockiervorrichtung 60 mittels eines Betätigungsschalters 61 in die Ein-Stellung gelegt wird. Befindet sich der Sicherungsstöpsel 70 in seiner Ausschaltstellung, so kann der Betätigungsschalter 61 der Schalt- und Blockiervorrichtung 60 nicht in die Ein-Stellung gelegt werden, weil der Blockierriegel 62 nicht in die Blockieröffnung 80 eingeführt werden kann.The guide element 76 also has a blocking opening 80, in which a blocking bar 62 of a switching and blocking device 60 engages when the switching and blocking device 60 by means of an actuation switch 61 in the on position is placed. The fuse plug 70 is in its Off position, the operating switch 61 can Switching and blocking device 60 not in the on position be placed because the locking bar 62 is not in the Blocking opening 80 can be inserted.

Das Gehäuse 2 der Schaltersicherungseinheit 1' weist einen Zapfen mit einer Durchgangsöffnung 7 mit einer Einführhilfe 36 auf. Die Positionierung der Durchgangsöffnung 7 in dem Gehäuse 2 in bezug auf die Durchgangsöffnung 75 in dem Griffteil 71 der Sicherungsstöpsels 70 wird in Fig. 5 deutlich.The housing 2 of the switch fuse unit 1 'has one Pin with a through opening 7 with an insertion aid 36 on. The positioning of the through opening 7 in the Housing 2 with respect to the through hole 75 in the handle part 71 of the fuse plug 70 is clear in FIG. 5.

In Fig. 5 befindet sich der Sicherungsstöpsel 70 in seiner Ausschaltstellung. Die Kontaktvorrichtung 52 ist nicht mehr mit dem Sicherungseinsatz 20 in Kontakt.In Fig. 5, the fuse plug 70 is in its Off position. The contact device 52 is no longer with the fuse link 20 in contact.

Der Sicherungsstöpsel 70 befindet sich in seiner Arbeitsposition, die Durchgangsöffnungen 75 und 7 überlappen sich nicht, so daß kein Verriegelungselement durch die Durchgangsöffnungen 7, 75 geführt werden kann.The safety plug 70 is in its working position, the through openings 75 and 7 do not overlap, so that no locking element through the through openings 7, 75 can be performed.

Erst bei einem Herausziehen des Sicherungsstöpsels 70 aus seiner Arbeitsposition (nicht gezeigt) kann eine Verriegelungsvorrichtung durch die Öffnungen 7, 75 hindurchgeführt werden, wie es analog in Fig. 3 gezeigt ist.Only when pulling the fuse plug 70 out its working position (not shown) can be a locking device passed through the openings 7, 75 as is shown analogously in FIG. 3.

Ein Herausziehen des Sicherungsstöpsels 70 aus seiner Arbeitsposition führt, wie im Zusammenhang mit Fig. 3 erläutert, dazu, daß der Haltebereich 73 des Sicherungsstöpsels 70 gegen die Positioniervorrichtung 3 bzw, die Kontaktvorrichtung 52 stößt, so daß der Sicherungsstöpsel 70 nicht in seine Einschaltstellung verschwenkt werden kann.Pulling the fuse plug 70 out of its working position leads, as explained in connection with FIG. 3, to the fact that the holding area 73 of the fuse plug 70 against the positioning device 3 or the contact device 52 bumps so that the fuse plug 70 is not in its on position can be pivoted.

In Fig. 6 ist ein Querschnitt längs der in Fig. 5 gezeigten Linie A-A dargestellt. Sichtbar ist hier insbesondere, wie der Sicherungsstöpsel 70, der ein Verbindungselement 77 in Form eines Schwalbenschwanzes aufweist, in eine korrespondierende Vertiefung des Führungselements 76 eingreift. Der Sicherungsstöpsel 70 wird daher durch einfaches Einschieben in die Schaltersicherungseinheit 1' form- und reibschlüssig mit dem Führungselement 76 verbunden.In Fig. 6 is a cross section along that shown in Fig. 5 Line A-A shown. It is particularly visible here how the Fuse plug 70, which is a connecting element 77 in the form has a dovetail, in a corresponding one Depression of the guide element 76 engages. The safety plug 70 is therefore simply inserted into the Switch fuse unit 1 'positively and frictionally with the Guide element 76 connected.

Es wird nochmals darauf hingewiesen, daß die Figuren lediglich schematische Darstellungen sind und insbesondere aus den Fig. keinerlei Beschränkungen bezüglich der Dimensionierung der gezeigten Elemente hergeleitet werden können. It is again pointed out that the figures are only are schematic representations and in particular from the Fig. no restrictions on the dimensioning of the shown elements can be derived.
