Abstract
Description
Die Erfindung betrifft eine Kabeldurchführung gemäß Oberbegriff des Anspruchs 1.The The invention relates to a cable bushing according to the preamble of the claim 1.
Bekannte Kabeldurchführungen dieser Art dienen dazu, Kabel durch die Wand eines Gehäuses, wie beispielsweise eines Schaltschranks, durchzuführen. Dabei dient die Einrichtung, in der die Kabel aufgenommen sind, zum einen der Abdichtung des Gehäuses gegen Eindringen von Schmutz oder Feuchtigkeit, zum anderen der Zugentlastung der Kabel. Die im Gehäuse angeordneten elektrischen Geräte dürfen dabei keinen zu großen Störungen durch elektromagnetische Strahlungen ausgesetzt werden. Zu diesem Zweck werden die Geräte möglichst vollständig durch das aus elektrisch leitendem Material hergestellte Gehäuse gekapselt. Eine Schwachstelle dieser Kapselung ist jedoch regelmäßig die Wandöffnung. Insbesondere die Mantelströme auf den Außenleitern der Koaxialkabel können die im Gehäuse angeordneten Geräte stören.Known Cable glands This type are used to cable through the wall of a housing, such as For example, a cabinet, perform. The device serves in which the cables are received, on the one hand, the sealing of the housing against Ingress of dirt or moisture, on the other hand, the strain relief the cable. The in the case arranged electrical appliances allowed to not too big Disturbances by be exposed to electromagnetic radiation. To this end become the devices preferably Completely encapsulated by the housing made of electrically conductive material. However, a weak point of this encapsulation is regularly the Wall opening. In particular, the sheath currents on the outer ladders the coaxial cable can be the in the case arranged devices to disturb.
Es ist daher Aufgabe der Erfindung, eine Kabeldurchführung der eingangs genannten Art derart weiterzubilden, dass elektromagnetische Störungen besser abgeschirmt werden können.It is therefore an object of the invention, a grommet of the aforementioned type such that electromagnetic Disturbances better can be shielded.
Die Aufgabe wird erfindungsgemäß durch eine Kabeldurchführung mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.The The object is achieved by a Grommet solved with the features of claim 1. Advantageous developments The invention is the subject of the dependent claims.
Der Erfindung liegt der Gedanke zugrunde, dass die Mantelströme der Koaxialkabel auf einfache Weise zum Ableitelement und von diesem zur Erde bzw. zur Masse abgeleitet werden. Hinter der Wand befindliche elektrische Geräte sind dann geringeren Störungen ausgesetzt, und die elektromagnetische Verträglichkeit der Kabeldurchführung ist verbessert.Of the Invention is based on the idea that the sheath currents of the coaxial cable in a simple way to Ableitelement and from this to the earth or be derived to the mass. Behind the wall are electrical appliances then lower disturbances exposed, and the electromagnetic compatibility of the cable gland is improved.
Es wird bevorzugt, dass das Ableitelement an der Wand angebracht ist. Insbesondere wenn die Wand Teil eines Gehäuses, wie eine Schaltschranks, ist, wird bevorzugt, dass das Ableitelement an der Innenseite des Gehäuses angebracht ist. Dort ist es von außen nicht sichtbar. Zweckmäßig ist das Ableitelement ein vorzugsweise flächig an der Wand anliegendes Ableitblech. Ein solches Blech ist einfach zu fertigen und einfach an der Wand zu befestigen und kann mit einer Vielzahl von Anschlussmöglichkeiten versehen werden, wenn eine große Zahl von Koaxialkabeln durch die Wandöffnung hindurchgeführt werden. In diesem Fall wird bevorzugt, dass das Ableitblech mehrere Kontaktelemente zum Anschließen von mit den Außenleitern mehrerer Koaxialkabel verbundenen Ableitdrähten aufweist.It it is preferred that the discharge element is attached to the wall. In particular, if the wall is part of a housing, such as a cabinet, it is preferred that the discharge element is attached to the inside of the housing is. There it is from the outside not visible. Is appropriate the diverter a preferably flat against the wall Deflector. Such a sheet is easy to manufacture and easy to attach to the wall and can provide a variety of connectivity options if a big one Number of coaxial cables are passed through the wall opening. In this case, it is preferred that the deflector plate a plurality of contact elements to connect with the outer conductors Having a plurality of coaxial cable connected Ableitdrähten.
Wenn die Wand elektrisch leitend ist, kann eine Verbindung des Ableitelements mit der Masse einfach dadurch hergestellt werden, dass es elektrisch leitend mit der Wand verbunden ist. Alternativ oder zusätzlich kann vorgesehen sein, dass an das Ableitelement ein zur Masse führendes Erdungskabel angeschlossen ist. Dies ist insbesondere dann vorteilhaft, wenn die Wand lackiert ist und ein elektrischer Kontakt zwischen der Wand und dem Ableitelement nicht einfach durch Anbringen des Ableitelements an der Wand hergestellt werden kann.If the wall is electrically conductive, a connection of the diverting element With the mass simply be made by making it electric conductively connected to the wall. Alternatively or additionally be provided that to the diverter a leading to the ground Grounding cable is connected. This is especially advantageous if the wall is painted and an electrical contact between the wall and the diverter not simply by attaching the Deriving element can be made on the wall.
Im Folgenden wird die Erfindung anhand eines in der Zeichnung schematisch dargestellten Ausführungsbeispiels näher erläutert. Es zeigtin the The invention will be described below with reference to a drawing in the drawing illustrated embodiment explained in more detail. It shows
