Derartige Sicherungsmodule sind an sich bekannt.Such backup modules are known per se.

Das Dokument DE 20 2010 005 718 U1 offenbart ein Sicherungsmodul gemäß dem Oberbegriff des Anspruchs 1.The document DE 20 2010 005 718 U1 discloses a fuse module according to the preamble of claim 1.

Verhindert werden soll mit einfachen konstruktiven Mitteln ein unbeabsichtigtes Ziehen des einen oder der beiden Leiter und/oder des Sicherungsbausteins unter Last.To be prevented with simple structural means unintentional pulling of one or both conductors and / or fuse block under load.

Die Erfindung hat die Aufgabe, dieses Problem zu lösen.The invention has the object to solve this problem.

Die Erfindung löst diese Aufgabe durch den Gegenstand des Anspruchs 1. Danach ist ein relativ zum Gehäuse bewegliches Mehrfunktionselement vorgesehen, das einerseits als ein Schaltelement ausgebildet ist, mit dem der Trennkontakt schließbar und/oder öffenbar (d.h. geöffnet werden kann) ist und das andererseits als ein Abdeckelement ausgebildet ist, mit welchem eine oder mehrere der Betätigungsöffnungen des Gehäuses ganz oder teilweise verdeckbar und freilegbar sind, so dass sie nicht zugänglich oder zugänglich sind.The invention solves this problem by the subject matter of claim 1. Thereafter, a relative to the housing movable multi-functional element is provided, which is formed on the one hand as a switching element with which the isolating contact closable and / or openable (ie can be opened) and the other hand a cover is formed, with which one or more of the actuating openings of the housing are completely or partially coverable and exposable, so that they are not accessible or accessible.

Derart können mit nur einer Bewegung und vorzugsweise nur einem Teil sowohl der Trennkontakt geschaltet und die Betätigungsöffnungen freigegeben oder verdeckt werden. Ein unbeabsichtigtes Ziehen der Sicherung oder eines Leiters unter Last wird damit verhindert. Es muss vielmehr zuerst das Mehrfunktionselement in seine andere Stellung bewegt werden.In this way, with only one movement and preferably only one part, both the isolating contact can be switched and the actuation openings can be released or covered. Unintentional pulling the fuse or a conductor under load is thus prevented. Rather, it must first be moved to the multi-functional element in its other position.

Vorteilhaft ist, dass das Mehrfunktionselement als einstückig oder ggf. auch mehrstückig ausgebildetes Mehrfunktionselement derart ausgestaltet ist, dass in einer seiner Stellungen der Trennkontakt geöffnet ist und die Betätigungsöffnungen im Gehäuse freigegeben sind und dass in der anderen Stellung der Trennkontakt geschlossen und die Betätigungsöffnungen im Gehäuse verdeckt sind.It is advantageous that the multi-functional element is designed as a one-piece or possibly multi-piece formed multi-functional element such that in one of its positions the isolating contact is open and the actuating openings are released in the housing and that closed in the other position of the isolating contact and conceals the actuating openings in the housing are.

Die Erfindung ist besonders vorteilhaft für Anschlussvorrichtungen für Leiterenden geeignet, die als Direktsteckkontakte ausgebildet sind und vorzugsweise einen Drücker zum Lösen einer Klemmfeder aufweisen. Die Erfindung ist aber nicht auf Anschlussvorrichtungen für Leiterenden beschränkt, die als Direktsteckkontakte ausgebildet sind. Sie ist vielmehr auch für Anschlussvorrichtungen für Leiterenden geeignet, die in einer anderen Anschlusstechnik ausgelegt sind.The invention is particularly advantageous for connection devices for conductor ends suitable, which are designed as direct plug contacts and preferably a pusher have to release a clamping spring. The invention is not limited to connection devices for conductor ends, which are designed as direct plug contacts. Rather, it is also suitable for connection devices for conductor ends, which are designed in a different connection technology.

So können die Anschlussvorrichtungen auch als Zugfederanschlüsse oder Schraubanschlüsse oder als isolationsdurchdringende Kontakte ausgebildet sein, sofern diese derart ausgelegt sind, dass sie eine Betätigungsöffnung in einem Gehäuse benötigen, um das Leiterende lösen zu können. Bei einem Schraubanschluss wären beispielsweise mit den Abdeckelementen/-bereichen des Mehrfunktionselementes die Schrauben der Anschlüsse in der einen Stellung mit geöffnetem Trennkontakt zugänglich und in der anderen Stellung mit geschlossenem Trennkontakt nicht. Weitere vorteilhafte Ausgestaltungen sind in den übrigen Unteransprüchen angegeben.Thus, the connection devices can also be designed as tension spring connections or screw connections or as insulation-penetrating contacts, insofar as these are designed such that they require an actuating opening in a housing in order to be able to release the conductor end. In a screw connection, for example, with the cover elements / areas of the multi-functional element, the screws of the terminals would be accessible in one position with an open isolating contact and not in the other position with a closed isolating contact. Further advantageous embodiments are specified in the remaining subclaims.

It is designed to be used with an area with the connection contacts 20, 21 in a (not shown here) frame to contact there corresponding contacts, such as blade contacts, a parent assembly not shown here. In this case, one of the connection devices 11 for a conductor end 9 becomes directly conducting with the corresponding connection device 20 on the second connection side connected and the other of the terminal devices 10 for a conductor end 8 is conductively protected by the fuse of the fuse block and connected via the isolating contact 27 with the connection contact 21 on the second connection side A.

Das Mehrfunktionselement 35 ist einerseits ein Trenner, mit dem der Trennkontakt 27 geöffnet werden kann. Dazu weist das Mehrfunktionselement 35 vorzugsweise ein Schwert 35a auf, mit welchem im geschlossenen Zustand des Trennkontaktes 27 federnd aneinander liegende Kontaktschenkel/-bereiche trennbar sind, so dass die leitende Verbindung zwischen den Kontaktschenkeln unterbrochen wird. In diesem Zustand kann der Sicherungsbaustein gezogen werden, da zwischen den Sicherungskontakten 22, 23 des Sicherungsbausteins 5 keine Spannungsdifferenz besteht.The multi-functional element 35 is on the one hand a disconnector, with which the isolating contact 27 can be opened. For this purpose, the multi-functional element 35 preferably has a sword 35a, with which in the closed state of the isolating contact 27 resilient contact legs / areas are separable, so that the conductive connection between the contact legs is interrupted. In this state, the fuse block can be pulled because there is no voltage difference between the fuse contacts 22, 23 of the fuse block 5.

Das Mehrfunktionselement 35 ist zudem ein Abdeckelement mit einem oder mehreren Abdeckabschnitten 35b, c, der/die hier so ausgestaltet sind, dass sie in der einen Stellung (Fig. 1 e) die Betätigungsöffnungen 12, 13 im Gehäuse 2 abdecken und in der anderen Stellung (Fig. 1 a) freigeben. In diesem freien Zustand (Fig. 1 a) sind die Betätigungsöffnungen 12, 13 so zugänglich, dass die Anschlussvorrichtungen 10, 11 für Leiter geöffnet und die Leiterenden herausgenommen werden können.The multi-functional element 35 is also a cover element with one or more cover sections 35b, c, which are designed here in such a way that they are in one position (FIG. Fig. 1 e) cover the actuating openings 12, 13 in the housing 2 and in the other position ( Fig. 1 a) release. In this free state ( Fig. 1 a) the actuating openings 12, 13 are accessible so that the connection devices 10, 11 can be opened for conductors and the conductor ends can be taken out.

Im vorliegenden Fall sind die beiden Anschlussvorrichtungen für die Leiterenden 8, 9 jeweils als Direktsteckkontakte ausgebildet. Daher können hier die Klemmfedern 16, 17, hier mit den vorzugsweise vorgesehenen Drückern 14, 15, geöffnet werden, um die Leiterenden herausnehmen zu können.In the present case, the two connection devices for the conductor ends 8, 9 are each formed as direct plug contacts. Therefore, here the clamping springs 16, 17, here with the preferably provided pushers 14, 15, are opened in order to take out the conductor ends can.

Dieses Herausnehmen der Leiterenden kann entsprechend nur erfolgen, wenn sich das Mehrfunktionselement 35, hier der Schieber, in seiner Trennstellung befindet bzw. in diese bewegt worden ist, so dass der Trennkontakt 27 geöffnet ist.This removal of the conductor ends can be done accordingly only if the multi-functional element 35, here the slide, is in its disconnected position or has been moved into it, so that the isolating contact 27 is opened.

Das Mehrfunktionselement 35 weist ferner einen Betätigungsansatz 35d auf. Hier steht der Betätigungsansatz 35d aus dem Gehäuse 2 vor. Der Betätigungsansatz 35d ist dazu ausgelegt, dass an ihm per Hand oder mit einem Werkzeug wie einer Zange das Mehrfunktionselement 35 zwischen der ersten und der zweiten Stellung beweglich, vorzugsweise verschieblich, ist.The multi-function element 35 also has an actuating projection 35d. Here, the actuating projection 35d protrudes from the housing 2. The actuating lug 35d is designed such that on it by hand or with a tool such as pliers, the multi-functional element 35 is movable, preferably displaceable, between the first and the second position.

Im vorliegenden Fall sind die Anschlussvorrichtungen 10, 11 für Leiterenden - wie bereits erläutert - als Direktsteckklemme(n) ausgebildet. Diese weisen jeweils einen leitenden Klemmkäfig 36 auf sowie jeweils die als Druckfeder wirkende (und vorzugsweise V-förmige) Klemmfeder 16, 17 zum Fixieren des elektrischen Leiterendes in der Direktsteckklemme durch Andrücken an die Innenwand des Klemmkäfigs 36. Dabei weist jede Klemmfeder 16, 17 einen um eine Schwenkachse in eine Schwenkrichtung verschwenkbaren Klemmschenkel auf, der von einem Rastzustand (R), in dem er an einem Haltemittel 37 verrastet ist, durch Verschieben des elektrischen Leiters in einen Klemmzustand verstellbar ist, in dem er vom Haltemittel 37 entrastet ist und den elektrischen Leiter 8, 9 gegen die Stromschiene - hier den Klemmkäfig - drückt. Hier ist das Haltemittel 37 als Feder mit einem Hinterschnitt 38 ausgestaltet. Dies ist vorteilhaft zum Einführen sehr feindrähtiger oder mehrlitziger Leiter, aber nicht zwingend.In the present case, the connection devices 10, 11 for conductor ends - as already explained - designed as a direct plug-in terminal (s). These each have a conductive clamping cage 36 and each acting as a compression spring (and preferably V-shaped) clamping spring 16, 17 for fixing the electrical conductor end in the Direktsteckklemme by pressing against the inner wall of the clamping cage 36. In this case, each clamping spring 16, 17 a about a pivot axis in a pivoting direction pivotable clamping leg on a latching state (R) in which it is locked to a holding means 37, is adjustable by moving the electrical conductor in a clamping state in which it is unlocked by the holding means 37 and the electrical Head 8, 9 against the busbar - here the clamping cage - presses. Here, the holding means 37 is designed as a spring with an undercut 38. This is advantageous for introducing very finely stranded or multi-stranded conductors, but not mandatory.
