In the case of this protective earth conductor terminal, an attachment and contact foot (4) is provided for the busbar (2) to make electrical contact with the carrier rail (5), which attachment and contact foot (4) is constructed as a solid metal part on which hook elements (6, 7) are provided for interaction with the carrier rail limbs and on which a long spring leg (8) is integrally formed. This allows reliable mechanical retention and good electrical contact to be achieved on and with the carrier rail (5) respectively, it being possible to produce the attachment and contact foot particularly easily, in one piece. <IMAGE>

Description

Die Erfindung betrifft eine Schutzleiterklemme mit einer in einem Isolierstoffgehäuse angeordneten, mit Leiteranschlüssen bestückten Stromschiene und einem mit der Stromschiene verbundenen Befestigungs- und Kontaktfuß, der als Metallteil ausgebildet ist und zur mechanischen und elektrischen Verbindung mit einer als Schutzleiter-Sammelschiene dienenden Tragschiene Hakenelemente und Federmittel zum Zusammenwirken mit den Tragschienenschenkeln aufweist.The invention relates to a protective conductor terminal with a arranged in an insulating housing, equipped with conductor connections busbar and with the busbar connected mounting and contact foot, which is designed as a metal part and for mechanical and electrical connection with a busbar serving as a protective conductor busbar hook elements and spring means for Has interaction with the mounting rail legs.

Bei einer bekannten Schutzleiterklemme der gattungsgemäßen Art (EP-A- 0 233 458) kann zwar der Kontaktfuß nicht nur die elektrische, sondern auch die mechanische Verbindung zu der Tragschiene übernehmen, und zwar für die Klemme insgesamt, so daß der Fußbereich ihres Isolierstoffgehäuses sehr einfach gehalten werden kann, doch hat der Kontaktfuß einen komplizierten und in der Herstellung teuren Aufbau. Es handelt sich um ein doppelschenkliges, kompliziertes Blechbiegeteil, in das eine gesondert herzustellende Feder in Art einer Blattfeder einmontiert werden muß. Der insbesondere durch die Hakenelemente des Blechbiegeteiles zu erreichende zuverlässige Halt auf der Tragschiene wird von daher mit einem erheblichen konstruktiven Aufwand erreicht.In a known protective conductor terminal of the generic type (EP-A-0 233 458), the contact foot can not only take over the electrical but also the mechanical connection to the mounting rail, for the terminal as a whole, so that the foot region of its insulating housing is very simple can be held, but the contact foot has a complicated and expensive to manufacture. It is a double-leg, complicated sheet metal bent part, in which a spring to be manufactured separately must be installed in the manner of a leaf spring. The reliable hold on the mounting rail, which can be achieved in particular by the hook elements of the bent sheet metal part, is therefore achieved with considerable design effort.

Es ist zwar auch schon eine Schutzleiterklemme bekannt geworden (DE-U- 77 12 331), bei der als Verbindungsstück zwischen der Stromschiene der Klemme und der Tragschiene ein massives Metallteil vorgesehen ist, doch wirkt dieses massive Metallteil aufgrund seiner Formgestalt für die mechanische Verbindung mit der Tragschiene nur so unzureichend zusammen, daß für die mechanische Verbindung auch besondere Montagefußgestaltungen am Isolierstoffgehäuse der Klemme erforderlich sind.Although a protective conductor terminal has already become known (DE-U-77 12 331), in which a solid metal part is provided as a connecting piece between the busbar of the terminal and the mounting rail, this solid metal part acts because of its shape for the mechanical connection the mounting rail only insufficiently together that for the mechanical connection also special mounting foot designs on the insulating housing of the terminal are required.

Ferner muß auch in dieses massive Metallteil als Federmittel wieder eine gesonderte Feder einmontiert werden. Gestaltet man die Verbindung zwischen Feder und massivem Metallteil beispielsweise durch einen einfachen Verspannvorgang einfach, kann es bei einem Verschieben der Klemme in Längsrichtung auf der Tragschiene dazu kommen, daß die Feder ihren Halt im Metallteil verliert.Furthermore, a separate spring must also be installed in this massive metal part as spring means. If you design the connection between the spring and the solid metal part, for example by a simple bracing process, it can happen that the spring loses its hold in the metal part when the clamp is moved in the longitudinal direction on the mounting rail.

Der vorliegenden Erfindung liegt von daher die Aufgabe zugrunde, eine Schutzleiterklemme der gattungsgemäßen Art zu schaffen, deren Befestigungs- und Kontaktfuß bei Gewährleistung eines zuverlässigen Haltes der Tragschiene besonders einfach herzustellen ist.The present invention is therefore based on the object to provide a protective conductor terminal of the generic type, the mounting and contact foot is particularly easy to manufacture while ensuring a reliable hold of the mounting rail.

Die erfindungsgemäße Lösung ergibt sich aus dem kennzeichnenden Teil des Patentanspruches 1.The solution according to the invention results from the characterizing part of patent claim 1.

Ein derartiger Kontaktfuß ist ein einstückiges massives Metallteil, an dem nicht mehr gesondert Federmittel montiert werden müssen. Die angeformten Hakenelemente geben einen zuverlässigen Halt auf der Tragschiene, wobei sich herausgestellt hat, daß die einstückig an das massive Metallteil angeformten Federbeine ausgehend von dem hier üblicherweise eingesetzten Material, beispielsweise einer Kupferlegierung, aufgrund ihrer Geometrie z. B. als einstückig angeformte Federbeine durchaus die gewünschte Funktion erfüllen können, also einerseits die erforderliche Federwirkung haben und andererseits auch noch ausreichend elastisch für eine bequeme Handhabung sind.Such a contact foot is a one-piece solid metal part, on which spring means no longer have to be mounted separately. The molded hook elements give a reliable hold on the mounting rail, and it has been found that the spring struts formed integrally on the solid metal part, starting from the material usually used here, for example a copper alloy, due to their geometry, for. B. as integrally molded struts can certainly perform the desired function, that is, on the one hand, have the required spring action and, on the other hand, are also sufficiently elastic for easy handling.

Man kann grundsätzlich einen derartigen Kontaktfuß in seiner endgültigen Form aus einer Metallplatte entsprechender Dicke herausstanzen. Möglich ist jedoch eine Ausgestaltung, nach der der Kontaktfuß durch Abtrennen von einem entsprechenden Profilstrang erhalten wird. Die Herstellung des Kontaktfußes läßt sich auf diese Weise praktisch abfallfrei durchführen.You can basically punch out such a contact foot in its final shape from a metal plate of appropriate thickness. However, a configuration is possible according to which the contact foot is obtained by separating it from a corresponding profile strand. The production of the contact foot can be carried out practically waste-free in this way.

Weitere bevorzugte Ausgestaltungen, die insbesondere Lage, Anzahl und Form der Federbeine betreffen, sind in den Unteransprüchen gekennzeichnet.Further preferred configurations, which relate in particular to the position, number and shape of the struts, are characterized in the subclaims.

Die in den Figuren 1 und 2 dargestellten Schutzleiterklemmen haben die üblichen Isolierstoffgehäuse 1, in die Stromschienen 2 eingesetzt sind, die mit Leiteranschlüssen 3 beliebiger, bekannter Bauart bestückt sind. Die Stromschienen 2 sind elektrisch und mechanisch fest mit einem Befestigungs- und Kontaktfuß 4, 4' verbunden, der seinerseits der elektrischen Verbindung der Stromschiene sowie der mechanischen Verbindung der Klemme insgesamt mit einer Tragschiene 5 dient, die bei derartigen Schutzleiterklemmen als Schutzleiter-Sammelschiene dient.The protective conductor terminals shown in Figures 1 and 2 have the usual insulating housing 1, in which busbars 2 are inserted, which are equipped with conductor connections 3 of any known type. The busbars 2 are electrically and mechanically firmly connected to a fastening and contact foot 4, 4 ', which in turn serves for the electrical connection of the busbar and the mechanical connection of the terminal overall with a mounting rail 5, which serves as a protective conductor busbar in such protective conductor terminals.

Bei dem in Figur 1 dargestellten Ausführungsbeispiel einer derartigen Schutzleiterklemme weist der Befestigungs- und Kontaktfuß 4 zwei Hakenelemente 6 und 7 auf, die aufgrund ihrer Formgebung praktisch Federwirkung haben. An den Befestigungs- und Kontaktfuß 4 ist bei dieser Ausführungsform ein besonders langes Federbein 8 einstückig angeformt. Es beginnt auf der einen Seite in der Nähe des Hakenelementes 6 und verläuft von dort über einen erheblichen Teil der Tragschienenbreite auf das andere Hakenelement 7 zu. Bei dieser Ausgestaltung hat das Hakenelement 7 eine Lagerschräge 9, die so lang bemessen ist, daß unterschiedlich lange und unterschiedlich dicke Tragschienenschenkel unterschiedlicher Tragschienen Platz finden. Das Federbein 8 wirkt auf die Oberseite des auf der Lagerschräge 9 liegenden Tragschienenschenkels. Das gegenüberliegende, als Festlager dienende Hakenelement 6 hat eine Steuerschräge 10, der eine nutartige Aufnahme 11 für das freie Ende des anderen Tragschienenschenkels folgt. Beim Aufsetzen der Klemme auf die Tragschiene wird der Befestigungs- und Kontaktfuß zunächst in Schräglage mit dem Hakenelement 7 und dem Federbein 8 mit dem entsprechenden Tragschienenschenkel in Verbindung gebracht. Beim Herunterdrücken läuft der andere Tragschienenschenkel längs der Steuerschräge 10 auf die Aufnahme 11 zu, wobei sich andere Tragschienenschenkel entsprechend auf der Lagerschräge 9 des Hakenelementes 7 hochschieben. Die Endlage wird durch das Federbein 8 gesichert.In the exemplary embodiment of such a protective conductor terminal shown in FIG. 1, the fastening and contact foot 4 has two hook elements 6 and 7, which practically have spring action due to their shape. At the mounting and contact foot 4 is in this Embodiment molded a particularly long strut 8 in one piece. It begins on one side in the vicinity of the hook element 6 and runs from there over a considerable part of the mounting rail width to the other hook element 7. In this embodiment, the hook element 7 has a bearing slope 9 which is dimensioned so long that space of different lengths and different thicknesses of different mounting rails can be accommodated. The strut 8 acts on the top of the support rail leg lying on the bearing slope 9. The opposite hook element 6, which serves as a fixed bearing, has a control bevel 10, which is followed by a groove-like receptacle 11 for the free end of the other mounting rail leg. When the clamp is placed on the mounting rail, the fastening and contact foot is first connected in an inclined position to the hook element 7 and the spring strut 8 to the corresponding mounting rail leg. When pressed down, the other mounting rail leg runs along the control slope 10 towards the receptacle 11, with other mounting rail legs correspondingly pushing up on the mounting slope 9 of the hook element 7. The end position is secured by the spring strut 8.

Mit dieser Ausführungsform können somit Tragschienenschenkel unterschiedlicher Ausgestaltung verwendet werden. Der Befestigungs- und Kontaktfuß 4 behält eine einfache Profilierung und hat ein besonders langes und von daher für die gewollte Funktion besonders geeignetes Federbein 8.With this embodiment, carrier rail legs of different designs can thus be used. The fastening and contact foot 4 maintains a simple profile and has a particularly long spring strut 8, which is therefore particularly suitable for the intended function.

Im Rahmen des Erfindungsprinzipes sind weitere bauliche Ausgestaltungen und Ausführungsformen ohne weiteres möglich, die jeweils an bestimmte Anwendungsfälle optimiert angepaßt werden können. So ist in Figur 2 eine Schutzleiterklemme grundsätzlich gleichen Aufbaus dargestellt, die nun einen Befestigungs- und Kontaktfuß 4' hat, der, ausgehend etwa vom mittleren Bereich, zwei kürzere Federbeine 8' und 8'' aufweist, die jeweils von dort auf einen der Tragschienenschenkel zu verlaufen und mit dessen Oberseite zusammenwirken. Bei dieser Ausgestaltung sind die Hakenelemente 6 und 7 in ihrer Geometrie so gehalten, daß auch sie wieder Federwirkung haben. Neben den beiden eigentlichen Federbeinen wirken somit auch wieder die Hakenelemente 6 und 7 wie Federbeine. Die insgesamt erforderliche und gewünschte Federbeinwirkung läßt sich also auf insgesamt vier federnd wirkende Elemente verteilen, womit man bei entsprechender Ausgestaltung eine besonders sichere abgefederte Halterung auf der Tragschiene bei guter Handhabbarkeit bezüglich der Verrastung auf der Tragschiene erreichen kann.Within the framework of the principle of the invention, further structural designs and embodiments are readily possible, each of which can be optimally adapted to specific applications. Thus, a protective conductor terminal of basically the same construction is shown in FIG. 2, which now has a fastening and contact foot 4 ', which, starting from approximately the central region, has two shorter spring struts 8' and 8 '', each of which stretches from there to one of the mounting rail legs to get lost and with the top of which work together. In this embodiment, the hook elements 6 and 7 are held in their geometry so that they also have spring action again. In addition to the two actual suspension struts, the hook elements 6 and 7 thus again act like suspension struts. The overall required and desired spring strut effect can thus be distributed over a total of four spring-acting elements, with which one can achieve a particularly secure suspension on the mounting rail with good handling with respect to the locking on the mounting rail with a corresponding design.

Bei dem in Figur 3 dargestellten Ausführungsbeispiel ist ein Befestigungs- und Kontaktfuß 4'' vorgesehen, bei dem das eine Hakenelement 7' einen verlängerten Federweg aufweist. Hierzu ist im dargestellten Ausführungsbeispiel das Hakenelement 7' seitlich über die Tragschiene hinaus verlängert und dann wieder C-förmig zum entsprechenden Tragschienenschenkel rückgebogen. An seinem mit diesem Tragschienenschenkel zusammenwirkenden Ende hat das Hakenelement 7' eine Lagerschräge 9'. Bei dieser Ausgestaltung ist es aufgrund des verlängerten Federweges des Hakenelementes 7' in besonderem Maße möglich, einen Toleranzausgleich zu den unterschiedlich ausfallenden Abmaßen der Tragschienen zu gewährleisten. Durch diese C-förmige Ausgestaltung des Hakenelementes 7' wird in besonderem Maße eine Kraft in horizontaler Richtung eingebracht, die den Festanschlag des gegenüberliegenden Hakenelementes 6 immer zuverlässig gegen die Tragschiene zieht. Auch bei beträchtlichen Toleranzen für die Tragschienenabmaße wird dadurch sichergestellt, daß der metallische Teil der Baugruppe in jedem Fall auch ohne Mithilfe des Isolierstoffgehäuses 1 sicher auf der Tragschiene 5 sitzt.In the exemplary embodiment shown in FIG. 3, a fastening and contact foot 4 ″ is provided, in which the one hook element 7 ′ has an extended spring travel. For this purpose, in the exemplary embodiment shown, the hook element 7 'is extended laterally beyond the mounting rail and then bent back again in a C-shape to the corresponding mounting rail leg. At its end interacting with this mounting rail leg, the hook element 7 'has a bearing slope 9'. In this embodiment, due to the longer spring travel of the hook element 7 ', it is particularly possible to ensure tolerance compensation for the different dimensions of the mounting rails. Due to this C-shaped configuration of the hook element 7 ', a force is introduced to a particular extent in the horizontal direction, which always reliably pulls the fixed stop of the opposing hook element 6 against the mounting rail. Even with considerable tolerances for the mounting rail dimensions, this ensures that the metallic part of the assembly is securely seated on the mounting rail 5 in any case, even without the aid of the insulating material housing 1.

Bei dieser Ausführungsform ist ferner wieder nur ein Federbein 8''' vorgesehen, das im Hinblick auf die Federungseigenschaften der Anordnung im übrigen aber für sich genommen relativ kurz sein kann und sich im dargestellten Ausführungsbeispiel etwa von der Mitte dieses Befestigungs- und Kontaktfußes 4" hin zu dem C-förmig ausgebildeten Hakenelement 7' erstreckt.In this embodiment, only one spring strut 8 '''is again provided, which, however, can be relatively short in itself with regard to the suspension properties of the arrangement and is shown in FIG Embodiment extends approximately from the center of this fastening and contact foot 4 "to the C-shaped hook element 7 '.
