Abstract

The cable entry bushes are for telephone or similar equipments where a large number of cables are led in. For easier handling and fixing the bushes, which are of elastomer moulding, are joined by narrow strips of the moulding material. The whole assembly can then be pushed into the pre-drilled plate (7) on the cubicle and snapped into position. Alternatively, individual bushes or groups may be cut off and fitted as necessary. The bushes are in the shape of stepped cones with a sealed end (11). To enter a cable the end is cut off and the cable pushed in until it is gripped by the appropriate bush diameter. Using this method the drilling can be the same as for a variety of cable diameters.

Description

KABELDURCHFÜHRUNG FÜR FERNE!ELDEKABES - ENDVERTE ILER CABLE ENTRY FOR DISTANT ELDEKABES - ENDVERTE ILER

ODER ENDVERZWEIGER Die Erfindung bezieht sich auf eine elastische Kabeldurchführung an farnmeldetechnischen Geräten vorzugsweise an Endverteilern und as Endverzweigern mit der Aufgabe, ankommende und abgehende wernmeldekabel die in ihrem Aussendurchmesser untereinander variieren, hindurchführen zu können, sodaß an den Kabeldurchführungsstellen eine spritzwasserdichte Abdichtung entsteht. Es sind mehrere solcher Kabeldurchführungsmöglichkeiten an fernmeldetechnischen Geräten bekannt, deren Nachteile im folgenden näher erläutert sind. OR END BREAKERS The invention relates to an elastic Cable entry on remote signaling devices, preferably on end distributors and as terminal distributors with the task of routing incoming and outgoing telecommunication cables vary in their outer diameter with each other, to be able to pass through, so that A splash-proof seal is created at the cable entry points. It are several such cable entry options on telecommunications equipment known, the disadvantages of which are explained in more detail below.

Nach -dem deutschen Patent 1221329 sind einzelne -DicjItungsstopfen aufgeführt was den Nachteil hat, daß diese gegenseitig nicht zusammenhängend sind und-somit leicht verlierbar sind. Eine anv.ere Version beinhaltet das deutsche Patent 2228498 mit dem Nachteil, daß zwei voneinander getrennte elastische Formteile verwendet werden. Aus dem deutschen Gebrauchsmuster 7142798 ist as bekannt eine Mehrfachkabeidurchführung zu verwenden mit dem Nachteil, daß mehrere solcher Kabeldurchführungen nicht zusammenhängend ausgebildet sind. Aus der deutschen Auslegeschrift 2418811 ist eine Dichtungsplatte bekannt die -aber zur Funktion eine zusätzliche Druckplatte benötigt.According to the German patent 1221329 there are individual -DicjItungsstopfen listed which has the disadvantage that these are not mutually related and are therefore easy to lose. A different version includes the German patent 2228498 with the disadvantage that two separate elastic molded parts are used will. A multiple cable leadthrough is known from the German utility model 7142798 to use with the disadvantage that several such cable bushings are not connected are trained. From the German Auslegeschrift 2418811 is a sealing plate known which -but to function requires an additional pressure plate.

Der Erfindung liegt die Aufgabe zugrunde für fernmeldetechnische Geräte eine elastische Kabeldurchführung zu schaffen, die mehrere Eabeldurchführungstüllen aufweist für Kabel unterschiedlicher Aussendurchmesser und daß diese Kabeldurchführungstüllen Bestandteile eines einstückigen Elastomere - Formteiles sind welches angeformte Einschnappwulste aufweist, die an Gegenstellen des Gehäuses eines fernmeldetechnischen Gerätes einzurasten in der Lage sind.The invention is based on the object for telecommunications equipment to create an elastic cable grommet that has several cable grommets has for cables of different outer diameters and that these cable grommets Components of a one-piece elastomer molded part are those which are molded on Has snap-in bulges that are attached to the counterparts of the housing of a telecommunications technology Device are able to lock into place.

Die Erfindung ist als ein Ausführungsbeispiel anhand der Figuren 1 bis 4 näher erläutert, dabei zeigen Figur 1 eine Ansicht in Richtung C aus Figur 2 Figur 2 einen Schnitt A-: B aus Figur 1 Figur 3 eine Einzelkabeldurchführungstülle der Kabeldurchführung Figur 4 eine Einzelkabeldurchführungstülle mit einem durchgeführten Kabel Eine aus einem Elastomere-Formstoff bestehende Kabeldurchführung besteht aus mehreren Einzelkabeldurchführungstüllen 1 die miteinander über Verbindungsstege 2 die eine Dicke X auf weisen, homogen verbunden sind. An den Stellen 4 ist keine Verbindung vorhanden, sodaß durch Abschneiden der Verbindungsstege 2, Einzelkabeldurchführungstüllen 1 im Reparaturfall abgenommen werde können. Dieser Vorgang ist auch dann erforderlich wenn an einem geschalteten Gerät eine Veränderung vorgenommen werden muß, die eine maßliche Abweichung des Kabelaussendurchmessers Y zur Folge hat. Vornehmlich dann, wenn ein neues Kabel mit kleinerem Aussendurchmesser Y eingeführt werden muß.The invention is illustrated as an exemplary embodiment on the basis of FIGS to 4 explained in more detail, FIG. 1 shows a view in the direction C from FIG 2 Figure 2 shows a section A-: B from Figure 1 Figure 3 shows a single cable grommet the cable entry Figure 4 shows a single cable entry grommet with a lead through cable A cable bushing made of an elastomer molded material consists of several individual cable grommets 1 which are connected to one another via connecting webs 2 which have a thickness X, are connected homogeneously. There is none at positions 4 Connection available, so that by cutting off the connecting webs 2, individual cable grommets 1 can be removed in the event of repairs. This process is also necessary then if a change has to be made to a switched device, the one dimensional deviation of the outer cable diameter Y results. Mainly then if a new cable with a smaller outer diameter Y has to be introduced.

Die Einzelkabeldurchführungstüllen 1 weisen Einschnappwulste 5 auf die aufgrung ihrer Elastizität in der Lage sind, nach erfolgtem Durchschieben durch Bohrungen 6 an einem Gehäuse 7 sich auszudehnen und somit eine axiale Fixierung in Richtung Z zu gewährleisten. Zudem weisen die Einzelkabeldurchführungstüllen 1 stufenartig ausgebildete Zapfenstücke 8 auf die im Durchmesser verschieden sind und an den Stellen 9 abgetrennt werden können, dodaß je nach Kabelaussendurchmasser Y eine spritzwasserdichte Umhüllung der Kabel an den Ringflächen 10 gewährleistet ist. Die Bodenflächen 11 der Endzapfenstücke 12 sind geschlossen geformt, sodaß wenn kein Kabel hindurchgeführt wird eine Abdichtung zwischen dem Geräteinnenraum 13 und der Aussenatmosphare gewährleistet ist.The individual cable entry grommets 1 have snap-in beads 5 which, due to their elasticity, are able to pass through after they have been pushed through Bores 6 on a housing 7 to expand and thus an axial fixation in the Z direction. In addition, the single cable grommets have grommets 1 step-like shaped journal pieces 8 on which are different in diameter and can be cut off at points 9, so that depending on the outer diameter of the cable Y a splash-proof covering of the cables on the annular surfaces 10 is guaranteed is. The bottom surfaces 11 of the end pin pieces 12 are shaped closed, so that if no cable is passed through, a seal is created between the interior of the device 13 and the outside atmosphere is guaranteed.
