Description
Die vorliegende Erfindung betrifft eine elektrisch leitende Kontaktanordnung mit einem lackierten Bolzen und einer darauf aufschraubbaren, lackschabenden Mutter gemäß dem Oberbegriff des Anspruchs 1.The The present invention relates to an electrically conductive contact arrangement with a painted bolt and a screw-on, paint-scraping Nut according to the preamble of claim 1.
Aus
der
Um insbesondere technische Probleme zu vermeiden, ist bei einer Massekontaktanordnung darauf zu achten, dass lackschabende Muttern verwendet werden, die beim Aufschrauben auf einen zugehörigen Gewindebolzen einen für die elektrische Leitfähigkeit erforderlichen Lackabrieb bewirken. Das Aufschrauben von gewöhnlichen Muttern bewirkt diesen Lackabrieb nicht, so dass in diesem Fall die elektrische Kontaktierung nicht hergestellt wird. Demzufolge ist es unbedingt erforderlich, zu gewährleisten, dass spezielle lackschabende Muttern verwendet werden.Around In particular, to avoid technical problems is in a ground contact arrangement on it to pay attention that paint scraping nuts are used in the Screw on an associated threaded bolt one required for the electrical conductivity Cause paint abrasion. Unscrewing ordinary Nuts do not cause this paint abrasion, so in this case the electrical contact is not made. As a result, It is imperative to ensure that special scratching nuts are used.
Die vorliegende Erfindung beschäftigt sich daher mit dem Problem, für eine elektrische leitende Kontaktanordnung der gattungsgemäßen Art eine verbesserte oder zumindest eine alternative Ausführungsform anzugeben, die sich insbesondere durch eine hohe Zuverlässigkeit auszeichnet.The The present invention therefore deals with the problem of for an electrical conductive contact arrangement of the generic Kind an improved or at least an alternative embodiment Specify, in particular, by a high reliability distinguished.
Dieses Problem wird erfindungsgemäß durch den Gegenstand des unabhängigen Anspruchs 1 gelöst. Vorteilhafte Ausführungsformen sind Gegenstand des abhängigen Anspruchs.This Problem is inventively by the subject of the independent claim 1 solved. advantageous Embodiments are the subject of the dependent Claim.
Die vorliegende Erfindung beruht auf dem allgemeinen Gedanken, bei einer elektrisch leitenden Kontaktanordnung mit einem lackierten Bolzen und einer darauf aufschraubbaren, lackschabenden Mutter, den Bolzen und die Mutter nach dem Schlüssel-Schloss-Prinzip auszubilden, so dass in jedem Fall gewährleistet werden kann, dass ausschließlich passende lackschabenden Muttern auf den Bolzen aufgeschraubt werden, die auch einen Lackabrieb bewirken und damit die geforderte elektrische Leitfähigkeit/Kontaktierung herstellen. Hierzu weist der Bolzen lediglich in einem ersten Teilbereich ein Außengewinde auf, an welches sich in Axialrichtung ein gewindefreier zweiter Teilbereich anschließt, der bis zu einem freien Ende des Bolzens reicht. Am freien Ende des Bolzens ist darüber hinaus zumindest ein radial abstehendes Formschlusselement vorgesehen, das mit einer an der Mutter ausgebildeten Ausnehmung derart zusammenwirkt, dass die Mutter in Axialrichtung über das Formschlusselement geschoben werden kann. Der gewindefreie zweite Teilbereich des Bolzens weist dabei eine zumindest geringfügig größere Axialerstreckung auf als die Mutter, so dass bei einem axialen Überschieben der Mutter über das wenigstens eine Formschlusselement die Mutter soweit in Axialrichtung verschoben werden kann, bis sie den ersten Teilbereich erreicht. Nach Erreichen des ersten Teilbereichs, in welchem das Außengewinde angeordnet ist, besteht zwischen dem Formschlusselement und der Ausnehmung an der Mutter kein Kontakt mehr, so dass sich die Mutter drehen lässt und dadurch auf das Außengewinde des Bolzens aufgeschraubt werden kann. Das wenigstens eine Formschlusselement erlaubt jedoch ausschließlich die Verwendung einer lackschabenden Mutter, die eine zu diesem Formschlusselement korrespondierende Ausnehmung aufweist. Ein Aufschieben bzw. Aufdrehen einer normalen Mutter ohne entsprechende Ausnehmung wird durch das am Bolzen vorgesehene Formschlusselement zuverlässig verhindert. Hierdurch kann eindeutig sichergestellt werden, dass zur Herstellung der elektrisch leitenden Kontaktanordnung ausschließlich geeignete Muttern, nämlich solche mit einer Ausnehmung, verwendet werden. Selbstverständlich ist dabei klar, dass das wenigstens eine Formschlusselement auch an der lackschabenden Mutter und die zugehörige Ausnehmung am Bolzen angeordnet sein kann. Auch ist das Vorsehen mehrerer Formschlusselemente und mehrerer Ausnehmungen denkbar.The The present invention is based on the general idea, in a electrically conductive contact arrangement with a painted bolt and a screw on it, schollenden mother, the bolt and to train the mother according to the key-lock principle, so that in any case it can be guaranteed that only suitable schollenden nuts are screwed onto the bolt, the also cause a paint abrasion and thus the required electrical Conduct conductivity / contacting. For this purpose, the bolt only in a first portion of an external thread on, in which in the axial direction a thread-free second Subarea connecting up to a free end of the Bolzens is enough. At the free end of the bolt is over it In addition, at least one radially protruding positive-locking element is provided, which cooperates with a recess formed on the nut, that the nut in the axial direction on the positive-locking element can be pushed. The unthreaded second portion of the bolt has an at least slightly larger Axial extent on than the nut, so that when axially slipping the mother on the at least one positive connection element the nut can be moved so far in the axial direction until it reached the first subarea. After reaching the first subarea, in which the external thread is arranged exists between the positive connection element and the recess on the mother no contact more so that the mother turns and thereby can be screwed onto the external thread of the bolt. However, the at least one interlocking element allows only the use of a paint scraping nut, the one to this positive locking element having corresponding recess. Sliding on or turning up a normal mother without appropriate recess is by the provided on bolt positive locking element reliably prevented. This can be clearly ensured that for the production the electrically conductive contact arrangement exclusively suitable nuts, namely those with a recess, be used. Of course, it is clear that the at least one positive-locking element also on the schatzschabenden Nut and the associated recess arranged on the bolt can be. Also, the provision of several positive locking elements and several recesses conceivable.
Bei einer weiteren vorteilhaften Ausführungsform der erfindungsgemäßen Lösung, sind das Außengewinde am Bolzen und das Innengewinde an der Mutter als Sondergewinde, insbesondere als nicht-metrische Gewinde, ausgebildet. Denkbar ist somit, dass der erfindungsgemäße Bolzen nicht nur ein oder mehrere Formschlusselemente aufweist, sondern zugleich auch ein Sondergewinde, wodurch ein zusätzlicher Sicherheitsaspekt zur Verwendung der richtigen Muttern geschaffen wird. Selbstverständlich ist dabei auch eine elektrisch leitende Kontaktanordnung denkbar, bei der der Bolzen keine Formschlusselemente und die zugehörige Mutter keine dazu korrespondierenden Ausnehmungen aufweist, wobei in diesem Fall sowohl der Bolzen als auch die Mutter ein korrespondierendes Sondergewinde aufweisen, welches ebenfalls die Verwendung herkömmlicher und dadurch nicht geeigneter Muttern zuverlässig unterbindet, da diese auf das Sondergewinde des Bolzens nicht aufgeschraubt werden können. Bei der alleinigen Verwendung von Sondergewinden ohne die zugehörigen Ausnehmungen an der Mutter bzw. die zugehörigen Formschlusselemente an dem Bolzen besteht jedoch unter Umständen die Gefahr, dass durch ein mechanisch hochbelastetes Aufschrauben die Mutter auf das Sondergewinde des Bolzens aufgeschraubt wird, ohne dass die Mutter ein dazu passendes Sondergewinde aufweist. Die Verwendung der Sondergewinde ist somit vorzugsweise nur in Verbindung mit dem Formschlusselement am Bolzen bzw. in Verbindung mit der Ausnehmung an der Mutter sinnvoll. Ein derartiges Sondergewinde kann bspw. eine abweichende Steigung, Ganghöhe oder ähnliches aufweisen. Insbesondere kann das Sondergewinde als nicht-metrisches Gewinde ausgebildet sein, wodurch bereits ein Großteil der herkömmlichen Muttern vom Aufschrauben ausgeschlossen werden kann.In a further advantageous embodiment of the solution according to the invention, the external thread on the bolt and the internal thread on the nut are designed as a special thread, in particular as a non-metric thread. It is thus conceivable that the bolt according to the invention not only has one or more positive locking elements, but at the same time also a special thread, whereby an additional safety aspect for using the correct nuts is created. Of course, an electrically conductive contact arrangement is also conceivable in which the bolt has no form-locking elements and the associated nut has no corresponding recesses, in which case both the bolt and the nut have a corresponding special thread, which is also the use of conventional and thus not Reliable nuts reliably prevented, as this on the Sonderge the bolt of the bolt can not be screwed on. In the sole use of special threads without the associated recesses on the nut or the associated positive locking elements on the bolt, however, there is a risk that the nut is screwed onto the special thread of the bolt by a mechanically highly loaded screwing without the mother to do so Has matching special thread. The use of the special thread is thus preferably only in conjunction with the form-locking element on the bolt or in conjunction with the recess on the nut makes sense. Such a special thread may, for example, have a different pitch, pitch or the like. In particular, the special thread may be formed as a non-metric thread, which already a large part of the conventional nuts can be excluded from screwing.
