Abstract
Description
Die Erfindung betrifft eine Kabelverschraubung für geschirmte Kabel mit einem rohrförmigen Doppelgewindestutzen aus einem stromleitenden Material und mit einem Kontakteinsatz zur Herstellung einer niederohmschen Verbindung der Schirmung eines eingeführten Kabels mit dem Doppelgewindestutzen sowie mit den weiteren Merkmalen des Oberbegriffs des Anspruchs 1. Die Erfindung betrifft ferner einen Kontakteinsatz der vorgenannten Art.The The invention relates to a cable gland for shielded cable with a tubular double threaded neck from an electrically conductive material and with a contact insert for Producing a low-resistance connection of the shielding of a introduced Cable with the double threaded connector and with the other features of the preamble of claim 1. The invention further relates a contact insert of the aforementioned type.
Derartige Kabelverschraubungen sind im Stand der Technik bekannt und werden als elektromagnetisch verträgliche oder kurz EMV-Kabelverschraubungen bezeichnet. Der Kontakteinsatz bildet zusammen mit dem Doppelgewindestutzen eine niederohmsche Verbindung zwischen dem Kabelschirm eines eingeführten geschirmten Kabels und der Gehäusewandung eines Gehäuses aus Metall oder metallisiertem Kunststoff, in das die Kabelverschraubung eingeschraubt wird. Gehäuse, Kabelverschraubung und Kabelschirm bilden dabei einen geschlossenen Faradayschen Käfig, der elektromagnetische Strahlungen vom Inneren des Gehäuses und des Kabels fernhält. Die Abdichtung verhindert zudem, daß Feuchtigkeit in das Gehäuseinnere eindringt.such Cable glands are known in the art and are as electromagnetically acceptable or EMC cable glands for short. The contact insert forms together with the double threaded connector a low ohmic Connection between the cable shield of an inserted shielded cable and the housing wall a housing made of metal or metallised plastic, into which the cable gland is screwed in. Casing, Cable gland and cable shield form a closed Faraday cage, the electromagnetic radiation from the inside of the case and the cable away. The seal also prevents moisture in the housing interior penetrates.
Eine
derartige EMV-Kabelverschraubung für geschirmte Kabel ist beispielsweise
aus
Sollen mehrere geschirmte Kabel in eine Gehäuse eingeführt werden, sind entsprechend mehrere EMV-Kabelverschraubungen erforderlich. Hierdurch wird die Kabeleinführung in das Gehäuse insgesamt jedoch unerwünscht sperrig. Werden hingegen mehrere Kabel mit einer einzigen EMV-Kabelverschraubung der vorgenannten Art in das Gehäuse eingeführt, sind die niederohmschen Verbindungen der jeweiligen Kabelschirme mit dem Gehäuse von unzureichender, nicht gleichbleibender Qualität.Should Several shielded cables are inserted into a housing are accordingly several EMC cable glands required. This will be the cable entry in the case Overall, however, undesirable bulky. However, multiple cables with a single EMC cable gland of the aforementioned type inserted into the housing are the low-resistance connections of the respective cable shields the housing of insufficient, not consistent quality.
Der Erfindung liegt daher die Aufgabe zugrunde, eine abgedichtete Kabelverschraubung für geschirmte Kabel mit einem Kontakteinsatz der Eingangs genannten Art bereitzustellen, die zur Einführung mehrerer geschirmter Kabel in ein Gehäuse geeignet ist, wobei eine gute niederohmsche Verbindung jedes einzelnen Kabelschirms mit der Gehäusewandung über die Kabelverschraubung sichergestellt ist.Of the Invention is therefore the object of a sealed cable gland for shielded Provide cable with a contact insert of the type mentioned, the introduction a plurality of shielded cable is suitable in a housing, wherein a good low-resistance connection of each cable shield with the Housing wall over the Cable gland is ensured.
Die Erfindung löst diese Aufgabe durch einen Kabelverschraubung mit den Merkmalen des Patentanspruchs 1 sowie durch einen Kontakteinsatz mit den Merkmalen des Patentanspruchs 18. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen 2 bis 17 beschrieben.The Invention solves this task by a cable gland with the characteristics of Patent claim 1 and by a contact insert with the features of Claim 18. Advantageous embodiments of the invention are in the subclaims 2 to 17 described.
Erfindungsgemäß weist der Kontakteinsatz eine Mehrzahl von elektrisch leitenden Klemmanordnungen auf, die zur einzelnen Einklemmung und niederohmschen Verbindung jeweils einer offengelegten Schirmung eines Kabels ausgebildet sind. Jedem in das Gehäuse eingeführten Kabel ist somit eine eigene Klemmanordnung zugeordnet, wobei die offengelegte Schirmung kontrolliert und definiert eingeklemmt wird und somit die niederohmsche Verbindung der Schirmung über die Klemmanordnung und den Kontakteinsatz mit dem Doppelgewindestutzen und darüber mit dem Gehäuse sichergestellt ist. Hierdurch ist eine gute niederohmsche Verbindung jedes einzelnen Schirmes mit der Gehäusewandung über die Kabelverschraubung gewährleistet. Die Quetschdichtung weist zudem erfindungsgemäß mehr als eine Durchgangsausnehmung auf. Jedem einzuführenden Kabel ist dabei eine eigene Durchgangsausnehmung zugeordnet. Sind mehr Durchgangsausnehmungen vorhanden als Kabel über die Kabelverschraubung in das Gehäuse eingeführt werden, so sind die freigebliebenen Durchgangsausnehmungen mit einem Blindstopfen verschlossen. Die erfindungsgemäße Quetschdichtung gewährleistet auch bei der Einführung mehrerer Kabel über die Kabelverschraubung in das Gehäuse eine gute Abdichtung und verhindert, daß Feuchtigkeit in das Gehäuseinnere eindringt.According to the invention the contact insert a plurality of electrically conductive clamping arrangements on, the single entrapment and low ohmic connection each of a disclosed shielding of a cable are formed. Everyone in the case introduced Cable is thus assigned its own clamping arrangement, wherein the revealed shielding is controlled and clamped defined and thus the low resistance connection of the shield over the Clamping arrangement and the contact insert with the double threaded connector and about that with the housing is ensured. This is a good low-resistance connection each individual screen with the housing wall over the cable gland guaranteed. The pinch seal also has more than one through-passage according to the invention on. Each to be introduced Cable is assigned its own through hole. are more through holes available than cables via the cable gland in the case introduced be, so are the remaining free through holes with a Blanking plug closed. The crush seal according to the invention ensures also at the introduction several cables over the cable gland in the housing a good seal and prevents moisture into the housing interior penetrates.
In einer vorteilhaften Ausgestaltung der Erfindung weist zumindest eine Klemmanordnung wenigstens zwei zusammenwirkende Klemmelement auf, zwischen die das einzuführende Kabel mit dessen offengelegter Schirmung klemmbar ist. Dabei ist die Klemmanordnung derart ausgebildet, daß im eingeklemmten Zustand des Kabels eine Kraft einer Bewegung der Klemmelement voneinander weg entgegenwirkt. Die Kraft wird dabei entweder von einer Feder aufgebracht, die an zumindest einem der Klemmelement angreift und dieses Klemmelement in Richtung auf das damit zusammenwirkende Klemmelement derselben Klemmanordnung kraftbeaufschlagt. Dabei kann sowohl das Klemmelement selbst als Federelement ausgebildet sein, als auch eine Feder an einem an sich starren jedoch schwenkbeweglich gelagertem Klemmelement angreifen. Die Klemmanordnung kann jedoch auch von einer Schraubklemme gebildet werden, wobei die Kraft zumindest einer Halteschraube einer Bewegung der Klemmelemente voneinander weg entgegenwirkt.In an advantageous embodiment of the invention has at least a clamping arrangement at least two cooperating clamping element, between the one to be introduced Cable with its exposed shield is clamped. Here is the clamping arrangement designed such that in clamped state of the cable a force of movement of the clamping element counteracts each other away. The power is either from a spring applied to at least one of the clamping element attacks and this clamping element in the direction of the cooperating Clamping element of the same clamping arrangement subjected to force. It can both the clamping element itself be designed as a spring element, as well as a spring on a per se rigid but pivotable Attack stored clamping element. However, the clamping arrangement can also be formed by a screw, wherein the force at least a retaining screw movement of the clamping elements from each other counteracts away.
