Abstract
Description
Die Erfindung bezieht sich auf eine Kabelverschraubung, umfassend einen mit einem Gehäuse verbindbaren Verschraubungsstutzen, eine im inneren des Stutzen einsetzbare Dichtung, sowie ein mit dem Stutzen verschraubbares Druckelement, welches auf die Dichtung, einen nach innen gerichteten Druck ausübt, so dass diese mit dem Kabel in Wirkeingriff tritt, ein Schirmkontaktelement, welches in elektrischer Verbindung mit dem Stutzen und dem vom Kabelmantel befreiten Kabelschirm steht.The The invention relates to a cable gland comprising a connectable with a housing Fitting, a seal that can be used in the interior of the nozzle and a screw-fastened to the nozzle pressure element, which on the seal, exerts an inward pressure, so that this comes into operative engagement with the cable, a screen contact element, which in electrical connection with the neck and the cable sheath freed cable shield is.
Bei
einer derartigen bekannten Kabelverschraubung (
Bei der vorliegenden Erfindung geht es darum, diese Verbindung zwischen Stutzen und Schirm einerseits mit einfachen Mitteln sicherzustellen und andererseits auch über einen großen Bereich unterschiedlicher Kabelaußendurchmesser eine sichere Verbindung zu bewerkstelligen.at The present invention is about this connection between Ensuring neck and shield on the other hand with simple means and then again a big Range of different cable outer diameter a secure connection to accomplish.
Erreicht wird dies bei einer Kabelverschraubung der eingangs genannten Art, dadurch dass das Schirmkontaktelement als gummi-elastischer Ringteil ausgebildet ist, welcher am oder innerhalb des Verschraubungsstutzen angeordnet ist, welches elektrisch leitend oder dessen Oberfläche wenigstens elektrisch leitend ist und eine Membran aufweist.Reached If this is the case with a cable gland of the type mentioned above, in that the shield contact element is designed as a rubber-elastic ring part is, which is arranged on or within the screw connection which is electrically conductive or whose surface is at least electrically is conductive and has a membrane.
Bei einer Ausführungsform der Erfindung ist dieser gummi-elastische Teil innerhalb des Stutzens angeordnet und besteht aus einem elastischen Material, welches in irgendeiner Weise elektrisch leitend gemacht worden ist.at an embodiment the invention, this rubber-elastic part is disposed within the nozzle and is made of an elastic material, which in any Has been made electrically conductive.
Bei einer alternativen Ausführungsform ist nicht der Korpus des Gummiringes leitend ausgebildet, sondern die Oberfläche hat eine entsprechende Beschichtung erhalten.at an alternative embodiment is not the body of the rubber ring conductive, but the surface has received a corresponding coating.
Der Ringteil ist bei einer Ausführungsform der Erfindung mit einer sich im wesentlichen radial erstreckenden Membran ausgebildet, die ihrerseits mit einem Durchgang versehen sein kann, so dass das Kabel dort durchgesteckt werden kann. Dies führt dann dazu, dass das Kabel die Membran verformt und dadurch schließlich eine Flächenberührung zwischen der verformten Membran und dem Schirmgeflecht erzeugt wird, was im Vergleich zu bekannten Kontaktierungen zu einem geringen Übergangswiderstand führt und eine sichere EMV Abschirmung bedeutet.Of the Ring part is in one embodiment of Invention having a substantially radially extending membrane formed, which in turn can be provided with a passage, so that the cable can be pushed through there. This then leads to cause the cable to deform the diaphragm, eventually causing a Surface contact between the deformed membrane and the screen mesh is produced, which in comparison to known contacts to a low contact resistance leads and a safe EMC shield means.
Der gummi-elastische leitende Teil kann ein separater Bauteil der Kabelverschraubung sein, er kann jedoch auch beim Herstellen des Stutzens hergestellt werden, indem zwei Materialien gleichzeitig verspritzt werden, wobei beide Materialen leitend, der ringförmige Teil jedoch darüber hinaus auch elastisch ausgebildet ist.Of the rubber-elastic conductive part can be a separate component of the cable gland However, it can also be produced when making the neck be sprayed by simultaneously spraying two materials, wherein both materials conductive, but the annular part beyond is also elastic.
Bei einer weiteren Ausführungsform befindet sich der gummi-elastische leitende Teil nicht innerhalb des Stutzens, sondern ist Bestandteil einer Verschraubungsmutter, die nach Einführung der Verschraubung in ein Gehäuse, vom Gehäuseinneren her auf das Gewinde der Kabelverschraubung geschraubt wird. Im Prinzip ist hier die Mutter mit dem zusätzlichen ringförmigen Teil so ausgebildet, dass dieser wiederum eine Membran aufweist und ansonsten der bislang beschriebenen Form und Funktion des gummielastischen Ringteils entspricht.at a further embodiment the rubber-elastic conductive part is not inside the nozzle, but is part of a nut, the after introduction the screwing into a housing, from the inside of the housing is screwed onto the thread of the cable gland. Basically Here is the mother with the extra annular Part designed so that in turn has a membrane and otherwise the previously described form and function of the rubber-elastic Ring part corresponds.
Eine weitere Ausführungsform wäre die Kombination, bei welcher sowohl der innerhalb der Verschraubung befindliche ringförmige Teil als auch die Innenverschraubungsmutter mit Membran verwendet wird.A another embodiment would be the combination in which both located within the screw annular part as well as the internal screw nut with membrane is used.
Die Erfindung wird nachstehend anhand der Zeichnung Beispielsweise erläutert.The Invention will be explained below with reference to the drawing example.
