Description

Die Erfindung betrifft eine Kabelabfangung nach dem Ober­ begriff des Patentanspruchs 1.The invention relates to a cable strain relief according to the upper Concept of claim 1.

In Kabelverzweigergestellen werden - in der Regel von un­ ten kommend - mehrere Lichtwellenleiter-Kabel durch die Bodenplatte geführt und mittels einer Zugabfangung fixiert. Aus der Patentschrift DE 41 04 530 C1 ist eine Zugabfangung bekannt, mit der ein sicheres und kabelscho­ nendes Befestigen erfolgt. Nachteilig ist allein die auf­ wendige Herstellung.In junction boxes, usually from un coming - several fiber optic cables through the Bottom plate guided and fixed with a strain relief. From the patent DE 41 04 530 C1 is one Strain relief known, with which a safe and cable cord Fixing takes place. The only disadvantage is that on agile manufacturing.

Der Erfindung liegt die Aufgabe zugrunde, für den Fall, daß nur Kabel befestigt werden sollen, die ein zugfestes Zentralelement aufweisen, die Kabelab­ fangung einfacher zu konzipieren. Sie soll sich beson­ ders für Glasfaserkabel und Hybridkabel, das sind Kabel, die sowohl elektrische Leiter als auch Lichtwellenleiter aufweisen, eignen.The invention is based on the object in the event that only cables should be attached to the have a tensile central element, the cables catch easier to design. It should be special for fiber optic cables and hybrid cables, these are cables, which are both electrical conductors and optical fibers have, are suitable.

Eine Vielzahl von Zugabfangungen soll außerdem auf kleinem Raum untergebracht werden können.A variety of strain reliefs are also said to be small Space can be accommodated.

Eine geeignete Kabelabfangung ist im Patentanspruch 1 angegeben.A suitable cable strain relief is in claim 1 specified.

Vorteilhafte Weiterbildungen sind den Unteransprüchen zu entnehmen.Advantageous further developments are in the subclaims remove.

Der besondere Vorteil der Kabelabfangung liegt in der Ein­ fachheit der Konstruktion. Die Zugkräfte des Kabels werden von der Befestigung des Zentralelementes aufgenommen. Das relativ empfindliche Kabel braucht durch die PUK-Schellen nur leicht angedrückt werden.The particular advantage of cable support lies in the one Expertise in construction. The tensile forces of the cable are  from the attachment of the central element. The relatively sensitive cables need through the PUK clamps just be pressed lightly.

Die Anzahl der Kabelabfangungen läßt sich einfach an dem Bedarf anpassen. Es braucht nur die entsprechende Anzahl von Abfangleisten in der Rahmenkonstruktion vorgesehen werden. Die erforderlichen PUK-Schellen können nach Bedarf aufgesetzt werden.The number of cable clamps can be easily found on the Adjust needs. You only need the corresponding number of support strips provided in the frame construction will. The required PUK clamps can be used as required be put on.

Vorteilhaft ist es, wenn die Abfangleisten gegeneinander (höhenmäßig), versetzt sind. Hierdurch wird eine bessere Zugänglichkeit erreicht, die durch seitliches Versetzen der PUK-Schellen und durch versetzte Bohrungen zur Auf­ nahme der Zentralelemente noch erhöht wird.It is advantageous if the support strips against each other (in height) are offset. This will make a better one Accessibility achieved by moving laterally the PUK clamps and through offset holes to open Central elements are increased.

Vorteilhaft ist ein Umschließen des Kabelendes durch einen Schrumpfschlauch. Ein zur Kontaktierung der gegebenenfalls vorhandenen metallenen Schirmung des Kabels verwendetes Kontaktelement wird so an die Schirmung gepreßt und erzielt hierdurch eine sichere elektrische Verbindung.Enclosing the cable end by an is advantageous Heat shrink tubing. One for contacting the if necessary existing metal shielding of the cable used Contact element is thus pressed against the shielding and achieved this ensures a secure electrical connection.

Ein Ausführungsbeispiel der Erfindung wird anhand von Figuren näher erläutert.An embodiment of the invention is based on Figures explained in more detail.

Es zeigen:Show it:

Fig. 1 die Vorderansicht einer Kabelabfangung, Fig. 1 is a front view of a cable strain relief,

Fig. 2 die Aufsicht der Kabelabfangung und Fig. 2 is the supervision of the cable strain relief and

Fig. 3 eine PUK-Schelle. Fig. 3 is a PUK clamp.

In die Seitenteile 11 (Bleche) eines Befestigungsrahmens sind untere Abfangungsleisten 8 und 16 sowie obere Ab­ fangungsleisten 9 und 17 eingesetzt. Die Abfangungsleisten sind in der Tiefe und der Höhe gestaffelt. Der Rahmen wird hier mittels einer Grundplatte 12, die Befestigungslöcher 15 aufweist, mit dem Verteilergestell verschraubt. Die Befestigung am Verteilergestell richtet sich jedoch nach dessen Konstruktion und kann auf die unterschiedlichste Art und Weise erfolgen.In the side parts 11 (sheets) of a mounting frame, lower support strips 8 and 16 and upper support strips 9 and 17 are used. The support strips are staggered in depth and height. The frame is screwed here to the distributor frame by means of a base plate 12 which has fastening holes 15 . The attachment to the distribution frame depends on its construction and can be done in a variety of ways.

Auf die unteren Abfangungsleisten 8 und 16 sind PUK-Schellen 10 zur Führung von Kabeln aufgesetzt. Aus Gründen der Über­ sichtlichkeit ist nur ein Kabel 1 eingezeichnet. Der Kabel­ mantel ist oberhalb der PUK-Schelle 10 entfernt und das Zentralelement 5 ist in eine Bohrung 6 der oberen Abfan­ gungsleiste 9 eingeführt und wird dort von Befestigungs­ schrauben 7 gehalten. Die Adern 19 ragen zur weiteren Ver­ drahtung oben heraus. Eine elektrische Schirmung 20 ist bei einem Einschnitt 2 in den Kabelmantel mit einem Kon­ taktelement 3 versehen, das über ein elastisches Erdungs­ band 13 an eine Erdungsklemme 14 angeschlossen ist.PUK clamps 10 for guiding cables are placed on the lower support strips 8 and 16 . For reasons of clarity, only one cable 1 is shown. The cable sheath is removed above the PUK clamp 10 and the central element 5 is inserted into a bore 6 of the upper Abfan supply strip 9 and is held there by fastening screws 7 . The wires 19 protrude above for further wiring. An electrical shield 20 is provided with an incision 2 in the cable sheath with a contact element 3 , which is connected via an elastic grounding band 13 to a grounding terminal 14 .

Durch einen Schrumpfschlauch 4 wird das Kabel im Bereich des entfernten Kabelmantels 2 zusammengehalten und abge­ dichtet.Through a shrink tube 4 , the cable is held together in the area of the removed cable sheath 2 and sealed.

Um eine bessere Zugänglichkeit für die PUK-Schellen 10 und die Befestigungsschrauben 7 zu erreichen, können die PUK- Schellen auf den unteren Abfangungsleisten 8 und 16 und die Bohrungen 6 in den oberen Abfangungsleisten 9 und 17 auch seitlich gegeneinander versetzt sein.In order to achieve better accessibility for the PUK clamps 10 and the fastening screws 7 , the PUK clamps on the lower support strips 8 and 16 and the bores 6 in the upper support strips 9 and 17 can also be laterally offset from one another.

In Fig. 2 ist die Kabelabfangung in der Draufsicht darge­ stellt. Zwei Kabel 1 sind hier direkt hintereinander be­ festigt. Die Befestigungsschrauben für das Zentralelement des ersten Kabels 1 sind entfernt. Die Seitenteile 11 (Bleche) sind durch Querstreben 18 miteinander verbunden. In Fig. 2, the cable strain relief in the top view is Darge. Two cables 1 are fastened here one behind the other. The fastening screws for the central element of the first cable 1 have been removed. The side parts 11 (sheets) are connected to one another by cross struts 18 .

Zum besseren Verständnis ist in Fig. 3 die Seitenan­ sicht einer PUK-Schelle dargestellt. Man erkennt, daß die PUK-Schellen auf die unteren Abfangungsleisten prob­ lemlos aufgesetzt werden können.For a better understanding the Seitenan view of a PUK clamp is shown in Fig. 3. It can be seen that the PUK clamps can easily be placed on the lower support rails.

Die Kabelabfangung kann für eine unterschiedliche Anzahl von Kabeln ausgeführt werden. Hierbei können natürlich auch mehr als zwei hintereinander angeordnete Paare von Abfangleisten vorgesehen sein. Ebenso kann sie in Abhän­ gigkeit von der Richtung der anzuschließenden Kabel auch waagerecht montiert werden.The cable clamp can be used for a different number run by cables. Of course you can also more than two pairs of Interception strips may be provided. It can also depend regardless of the direction of the cables to be connected be mounted horizontally.
