Description

Die vorliegende Erfindung betrifft eine Erdanschluss-Vorrichtung für ein Metallprofil, insbesondere ein Tragprofil, gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a ground terminal device for a metal profile, in particular a support profile, according to the preamble of claim 1.

Bei den bislang eingesetzten Erdanschlüssen liegt die Kontaktlasche mit einer planen Flächen an einer zugeordneten Fläche des aus einem Leichtmetall, insbesondere Aluminium bestehenden Tragprofils an.In the earth connections used so far, the contact lug with a flat surfaces on an associated surface of the present of a light metal, in particular aluminum support profile.

Allerdings ist hierbei eine zuverlässige Erdung nicht in jedem Fall gewährleistet, da beispielsweise durch dazwischen liegende Verschmutzungen in Form von Staubkörnern oder dergleichen oder durch in dem Metallprofil vorhandene Riefen eine Kontaktunterbrechung vorhanden sein kann, welche die Funktionsfähigkeit des Erdanschlusses insgesamt beeinträchtigt.However, in this case a reliable grounding is not guaranteed in any case, since for example by intervening dirt in the form of dust grains or the like or by existing in the metal profile grooves interruption may be present, which affects the overall functionality of the ground terminal.

In der Folge der insoweit nicht vollständigen Anlage der Kontaktlasche am Metallprofil kann es zu Korrosionen kommen, durch die ebenfalls die Kontaktierung erheblich beeinflusst wird.As a result of the extent not complete installation of the contact tab on the metal profile can lead to corrosion, which also significantly affects the contact.

Durch die lediglich flächige Anlage der Kontaktplatte an dem Metallprofil, wobei die Kontaktplatte mittels einer Klemmschraube befestigt ist, besteht die Gefahr, dass sich die Kontaktplatte, insbesondere durch die beim Fahrbetrieb eines Schienenfahrzeuges, bei dem die Erdanschluss-Vorrichtung vorzugsweise eingesetzt wird, verdreht, unter Mitnahme des Erdungskabels, das somit entsprechenden Zugkräften ausgesetzt wird. Darüber hinaus kann der Kontakt zwischen der Kontaktplatte und dem Metallprofil durch das Verdrehen der Kontaktplatte unterbrochen werden, so dass auch hierdurch die Funktionssicherheit eingeschränkt ist.Due to the only flat contact surface of the contact plate on the metal profile, wherein the contact plate is fixed by a clamping screw, there is a risk that the contact plate, in particular by the driving operation of a rail vehicle, in which the ground terminal device is preferably used, twisted, under Driving the grounding cable, which is thus exposed to corresponding tensile forces. In addition, the contact between the contact plate and the metal profile can be interrupted by the rotation of the contact plate, so that thereby the functional reliability is limited.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die Erdanschluss-Vorrichtung der gattungsgemäßen Art so weiter zu entwickeln, dass mit konstruktiv einfachsten Mitteln die Funktionssicherheit verbessert wird.The present invention has for its object to further develop the ground terminal device of the generic type so that the functional reliability is improved with structurally simplest means.

Diese Aufgabe wird durch eine Erdanschluss-Vorrichtung mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a ground terminal device having the features of claim 1.

Durch diese konstruktive Ausbildung wird gewährleistet, dass die Kontaktlasche dauerhaft und stets kontaktierend am Metallprofil anliegt. Eine Unterbrechung des Kontaktes ist somit ausgeschlossen.This structural design ensures that the contact tab rests permanently and always contacting the metal profile. An interruption of the contact is thus excluded.

Nach einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass die Kontaktlasche im Bereich ihrer Anlagefläche mit dem Metallprofil erhabene Ausformungen, vorzugsweise kegel- oder pyramidenförmig aufweist, die sich beim Festklemmen mit dem Metallprofil in dies eindrücken und dabei eine gasdichte Anlage erreichen, durch die eine Korrosion des Metallprofil verhindert wird.According to an advantageous embodiment of the invention, it is provided that the contact tab in the region of its contact surface with the metal profile raised formations, preferably conical or pyramid-shaped, which press when clamping with the metal profile in this and thereby achieve a gas-tight system, by the corrosion the metal profile is prevented.

Prinzipiell sind jedoch auch andere Formen der Erhebungen denkbar, die dann mit entsprechenden Vertiefungen des Metallprofils korrespondieren.In principle, however, other shapes of the elevations are conceivable, which then correspond to corresponding recesses of the metal profile.

Neben der Kontaktierung im Anlagebereich der Noppen mit dem Metallprofil stellt sich nach einem Festklemmen der Kontaktlasche auch ein zumindest linienförmiger Kontakt im Bereich der Auflagefläche der Kontaktlasche im übrigen mit dem Metallprofil ein.In addition to the contacting in the contact region of the knobs with the metal profile, after a clamping of the contact tab, at least a line-shaped contact in the area of the contact surface of the contact tab also exists with the metal profile.

Besonders einfach lassen sich die Noppen, also die Erhebungen durch Prägen herstellen, wobei eine solche Prägung durch ein geeignetes Werkzeug, beispielsweise ein Gesenk als Matrize und ein entsprechender Stift als Patrize eingebracht wird.The knobs, that is to say the elevations, can be produced in a particularly simple manner by embossing, with such an embossing being introduced by means of a suitable tool, for example a die as a die and a corresponding pin as a male part.

Die Dimensionierung der Noppen ist so zu wählen, insbesondere deren Höhe, dass sie sich problemlos in die Anlagefläche des Metallprofils eindrücken.The dimensioning of the knobs should be chosen so, in particular their height that they press easily into the contact surface of the metal profile.

Die Befestigung der Kontaktlasche kann mittels eines Nutsteines, vorzugsweise eines T-Nutsteines erfolgen, der in einer Längsnut des Metallprofils geführt und an der Innenwandung des als Hohlprofil ausgebildeten Metallprofils klemmend anliegt.The attachment of the contact tab can be done by means of a sliding block, preferably a T-slot block, which is guided in a longitudinal groove of the metal profile and clamped against the inner wall of the metal profile designed as a hollow profile.

Zur exakten Positionierung der Kontaktlasche ist diese verdrehsicher am Metallprofil gehalten, wozu Anschlagwarzen an der Kontaktlasche vorgesehen sind, die an den Wandungen der Längsnut anliegen. Diese Anschlagwarzen können ebenfalls durch Prägen eingebracht sein. Selbstverständlich sind auch andere Formen von Anschlägen denkbar, die in die Längsnut des Metallprofils ragen und an den sich gegenüber liegenden Wandungen anliegen.For exact positioning of the contact lug this is held against rotation on the metal profile, including stop warts are provided on the contact tab, which bear against the walls of the longitudinal groove. This stop warts can also be introduced by embossing. Of course, other forms of attacks are conceivable that protrude into the longitudinal groove of the metal profile and rest against the opposing walls.

Weitere vorteilhafte Ausbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Further advantageous embodiments of the invention are characterized in the subclaims.

In den Figuren ist ein Erdanschluss eines Metallprofils 1, vorzugsweise aus einem Leichtmetall wie Aluminium dargestellt, wobei das Metallprofil 1 Bestandteil insbesondere eines Schienenfahrzeuges ist.In the figures, a ground terminal of a metal profile 1, preferably made of a light metal such as aluminum, wherein the metal profile 1 is part of a particular rail vehicle.

Der Erdanschluss weist eine Kontaktlasche 2 auf, die an dem Tragprofil 1 befestigt ist und an der ein Erdungskabel 3 angeschlossen ist.The ground terminal has a contact tab 2 which is fixed to the support profile 1 and to which a grounding cable 3 is connected.

Erfindungsgemäß liegt die Kontaktlasche 2 formschlüssig verdrehgesichert an dem Metallprofil 1 an.According to the invention, the contact tab 2 is positively secured against rotation on the metal profile 1.

Für den Formschluss sind durch beispielsweise Prägen Vorsprünge 9 in die Kontaktplatte 2 eingebracht, die, wie insbesondere die Figur 2 b) bzw. Figur 4 d) zeigen, kegelstumpfförmig ausgebildet sind und die sich in die Außenwandung des Metallprofils 1 eingraben. Hierdurch wird eine gasdichte Kontaktierung zwischen der Kontaktlasche 2 und dem Metallprofil 1 erreicht.For the positive connection projections 9 are introduced into the contact plate 2, for example, by embossing, which, in particular, the figure 2 b) or Figure 4 d) show are frusto-conical and dig into the outer wall of the metal profile 1. As a result, a gas-tight contact between the contact tab 2 and the metal profile 1 is achieved.

Anstelle der kegelstumpfförmigen Ausbildung der Vorsprünge 9 können diese auch spitz ausgeformt sein, als Kegel oder Pyramide. Denkbar ist auch eine zylindrische Formgebung.Instead of the frustoconical design of the projections 9, these can also be formed pointed, as a cone or pyramid. Also conceivable is a cylindrical shape.

Die Kontaktlasche 2 ist mit dem Metallprofil 1 durch Klemmung verbunden, wozu ein T-förmiger Nutstein 5 vorgesehen ist, in den eine Schraube 6, welche die Kontaktlasche 2 durchtritt und deren Kopf auf einer Scheibe 7 aufliegt, eingedreht ist.The contact tab 2 is connected to the metal profile 1 by clamping, including a T-shaped sliding block 5 is provided, into which a screw 6, which passes through the contact tab 2 and the head rests on a disc 7, is screwed.

Dieser T-förmige Nutstein 5 ist einer Längsnut 4 des Metallprofils 1 geführt und stützt sich innenseitig an der die Längsnut 4 begrenzenden Wandung des Metallprofils 1 ab.This T-shaped sliding block 5 is guided a longitudinal groove 4 of the metal profile 1 and is supported on the inside of the longitudinal groove 4 bounding wall of the metal profile 1 from.

Um eine Verdrehsicherung der Kontaktlasche 2 zu erreichen, weist diese Anschlagwarzen 8 auf, von denen jeweils zwei an einer Wand der Längsnut 4 anliegen. Diese Anschlagwarzen 8 können ebenfalls durch Prägen eingebracht sein.In order to achieve an anti-rotation of the contact lug 2, this has stop lugs 8, of which two each bear against a wall of the longitudinal groove 4. These stop projections 8 can also be introduced by embossing.

Die Höhe der Vorsprünge 9 ist so bemessen, dass sie sich ohne weiteres in das Metallprofil 1 eindrücken lassen, wobei anschließend die Kontaktlasche 2 flächig auf der zugeordneten Seite des Metallprofils 1 anliegt.The height of the projections 9 is dimensioned so that they can be pressed easily into the metal profile 1, wherein then the contact tab 2 rests flat on the associated side of the metal profile 1.

Der Nutstein 5 ist so bemessen, dass er zwar in Gebrauchsstellung die Wandung des Metallprofils 1 hintergreift, zum Einführen jedoch in seiner Breite geringer ist als die Breite der Längsnut 4, so dass er von oben her in die Längsnut 4 gesteckt werden kann und lediglich zur Festklemmung um 90° zu verdrehen ist.The sliding block 5 is dimensioned such that it engages in the position of use, the wall of the metal profile 1, for insertion, however, is less in width than the width of the longitudinal groove 4, so that it can be inserted from above into the longitudinal groove 4 and only for Clamping is to be rotated by 90 °.

Bei dem in den Figuren 1 und 2 gezeigten Ausführungsbeispiel ist die Kontaktlasche 2 als ebene Platte ausgebildet, während sie in der Figur 3 winkelförmig gestaltet ist, so dass hierbei das Erdungskabel 3 senkrecht verlaufend zur Auflagefläche des Metallprofils 1 angeschlossen ist.In the embodiment shown in Figures 1 and 2, the contact tab 2 is formed as a flat plate, while it is designed angularly in Figure 3, so that in this case the grounding cable 3 is connected perpendicular to the support surface of the metal profile 1.

In der Figur 1a) ist der Erdanschluss in einer Seitenansicht zu sehen, in b) in einer Draufsicht und in c) in einer perspektivischen Ansicht.In FIG. 1a), the ground connection can be seen in a side view, in b) in a plan view and in c) in a perspective view.

Die Figur 2 zeigt die Kontaktlasche 2 als Einzelheit und zwar in a) in einer Seitenansicht in b) in einem Teilausschnitt, gemäß der Linie A - A in Figur a). In Figur 2c) ist die Kontaktlasche 2 in einer Draufsicht und in d) in einer Seitenansicht, in e) in einer geschnittenen Seitenansicht, entsprechend der Linie B - B in c) und in f) in einer perspektivischen Ansicht, dargestellt.FIG. 2 shows the contact tab 2 as a detail, namely in a) in a side view in b) in a partial detail, along the line A - A in FIG. In FIG. 2c) the contact lug 2 is shown in a plan view and in d) in a side view, in e) in a sectional side view, corresponding to the line B-B in c) and in f) in a perspective view.
