Description

Kabelabgang Beschreibung  Cable outlet Description
Die Erfindung geht aus von einem Kabelabgang nach dem Oberbegriff des unabhängigen Anspruchs 1.  The invention is based on a cable outlet according to the preamble of the independent claim 1.
Derartige Kabelabgänge werden benötigt, um Kabel die von Geräten, Gehäusen oder Steckverbindern weggeführt werden, an dem Gerät oder Steckverbinder zu fixieren, mechanisch zu befestigen und diese mechanisch zu stabilisieren. Kabelabgänge die eine mechanische Stabilisierung des Kabels ermöglichen, werden auch als Knickschutz bezeichnet. Such cable outlets are required to fix cables, which are led away from devices, housings or connectors, to the device or connectors, to fix them mechanically and to stabilize them mechanically. Cable outlets that enable mechanical stabilization of the cable are also known as kink protection.
Dabei umschließen derartige Kabelabgänge das Kabel und sind an einem Kabelabgangsstutzen befestigt. Der Kabelabgangsstutzen ist am Gehäuse, Gerät oder Steckverbinder, in welches das Kabel führt angeformt. Im Stand der Technik verfügen derartige Kabelabgangsstutzen zu meist über ein Gewinde, welches meist als Außengewinde ausgebildet ist. Such cable outlets enclose the cable and are attached to a cable outlet spigot. The cable outlet is molded to the housing, device or connector into which the cable passes. In the prior art, such cable outlet connection to most of a thread, which is usually designed as an external thread.
Auf das Gewinde wird ein Kabelabgang mit einem korrespondierenden Gewinde aufgeschraubt. Durch Aufschrauben wird meist eine Klemmhülse oder ein in dem Kabelabgang vorgesehenes Klemmglied mechanisch verformt oder radial nach innen gedrückt, wodurch das Kabel innerhalb des Kabelabgangs mechanisch fixiert wird. On the thread a cable outlet is screwed with a corresponding thread. By screwing a clamping sleeve or provided in the cable outlet clamping member is usually mechanically deformed or pressed radially inward, whereby the cable is mechanically fixed within the cable outlet.
Nachteilig wirkt sich bei dieser Art von Kabelabgang aus, dass diese nur bedingt gegen Verschmutzung und das Eindringen von Feuchtigkeit geschützt sind. Zudem wird das geführte Kabel mechanisch sehr stark beansprucht. Bei zu festem Aufdrehen des Kabelabgangs kann es zu Verletzungen des Kabels kommen. Weiterhin ist diese Art von Kabelabgang nicht gegen Manipulationen gesichert und kann beliebig oft aufgeschraubt und wieder zugeschraubt werden. Für den Nutzer ist nicht erkennbar, ob die Verbindung bereits geöffnet und ggf. manipuliert wurde. A disadvantage of this type of cable outlet that they are only partially protected against contamination and the ingress of moisture. In addition, the guided cable is mechanically stressed very strong. Over tightening the cable outlet may cause injury to the cable. Furthermore, this type of cable outlet is not secured against manipulation and can be screwed on and screwed on as often as desired. It is not clear to the user whether the connection has already been opened and possibly manipulated.
Eine weitere bekannte Art von Kabelabgängen sind Kabelabgänge welche direkt in der Fertigung umspritzt werden. Dabei wird das Kabel und der Kabelabgangsstutzen maschinell umspritzt. Dies ist eine sehr vorteilhaft Art von Kabelabgängen, da diese gleichzeitig als Knickschutz genutzt werden könne. Another known type of cable outlet are cable outlets which are molded directly in the production. Here, the cable and the cable outlet nozzle is mechanically overmolded. This is a very advantageous type of cable outlet, as it could be used as a kink protection at the same time.
Nachteilig wirkt sich bei umspritzten Kabelabgängen jedoch aus, dass diese in einer Fertigung mit entsprechenden Maschinen hergestellt werden müssen. Eine Konfektionierung vor Ort ist ohne Maschinen und entsprechende Ausstattung nicht möglich. A disadvantage of overmolded cable outlets, however, is that they must be manufactured in a production with appropriate machinery. An assembly on site is not possible without machines and corresponding equipment.
Die Aufgabe der Erfindung besteht darin, einen Kabelabgang vorzustellen, welcher die Vorteile der bereits aus dem Stand der Technik bekannten Lösungen vereinbart. Der Kabelabgang soll feldkonfektionier- bar sein, kein spezielles Werkzeug oder Maschinen zur Herstellung benötigen und dabei umweltdicht, leicht handhabbar, sowie sicher gegen Manipulation und unberechtigtes Öffnen sein und eine große Bandbreite an verschieden starken Kabeln aufnehmen können. The object of the invention is to provide a cable outlet, which agrees the advantages of the already known from the prior art solutions. The cable outlet should be field-assembly-ready, require no special tools or machines for production and be environmentally friendly, easy to handle, as well as safe against manipulation and unauthorized opening and can accommodate a wide range of cables of different strengths.
Die Aufgabe wird durch die kennzeichnenden Merkmale des unabhängigen Anspruchs 1 sowie das Verfahren nach Anspruch 9 gelöst. The object is solved by the characterizing features of independent claim 1 and the method according to claim 9.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben. Advantageous embodiments of the invention are specified in the subclaims.
Bei der Erfindung handelt es sich um einen Kabelabgang, welcher aus einem hülsenförmigen Grundkörper gebildet ist. Wobei der Grundkörper einteilig oder aus mehreren Teilsegmenten bestehen kann. Bei einer Ausführung aus mehreren Teilsegmenten ist vorteilhaft, diese hermaphroditisch auszubilden. So muss nur eine Sorte Teile vorgehalten werden. In the invention, it is a cable outlet, which is formed from a sleeve-shaped base body. Where the basic body can consist of one or more sub-segments. In an embodiment of a plurality of sub-segments is advantageous to form them hermaphroditic. So only one sort of parts needs to be kept.
Der Grundkörper ist zum Aufstecken oder Aufschrauben auf einen Kabelabgangsstutzen vorgesehen. Der Kabelabgangsstutzen ist dabei an einem Gehäuse, Gerät oder Steckverbinder vorgesehen aus welchem ein Kabel weggeführt werden soll. Dabei umgibt der Kabelabgangsstutzen vorteilhaft das wegführende Kabel. The main body is intended to be plugged or screwed onto a cable outlet spigot. The cable outlet connection is provided on a housing, device or connector from which a cable is to be led away. In this case, the cable outlet nozzle advantageously surrounds the cable leading away.
Der Kabelabgangsstutzen kann dabei rund oder eckig ausgeführt sein. Je nach Ausführung des Kabelabgangsstutzens ist auch der Kabelabgang dementsprechend auszuführen. Dabei kann entweder der gesamte Grundkörper des Kabelabgangs die Form des Kabelabgangsstutzens aufweisen, oder nur die Innenseite des Kabelabgangs entsprechend ausgebildet sein um eine formschlüssige Verbindung zwischen Kabelabgang und Kabelabgangsstutzen zu gewährleisten. The cable outlet connection can be round or square. Depending on the version of the cable outlet spigot and the cable outlet is carried out accordingly. In this case, either the entire main body of the cable outlet have the shape of the cable outlet nozzle, or only the inside of the cable outlet be designed to ensure a positive connection between the cable outlet and cable outlet connection.
Erfindungsgemäß ist an der Innenseite des Grundkörpers des Kabelabgangs ein Polymer vorgesehen, welches aushärtbar ist. Dabei kann es sich um verschiedene Arten von aushärtbaren Polymeren handeln. Polymere die ein Lösungsmittel enthalten, welches sich durch Ausdunstung verflüchtige und so das Polymer erstarrt sind denkbar, ebenso Zwei-Komponenten-Polymer die bei Vermischung aushärten. Auch können Polymere genutzt werden, die durch Licht- oder Temperatureinwirkung aushärten. According to the invention, a polymer is provided on the inside of the main body of the cable outlet, which is curable. These may be different types of thermosetting polymers. Polymers which contain a solvent which evaporates by evaporation and so the polymer solidifies are conceivable, as well as two-component polymer which harden on mixing. It is also possible to use polymers which cure by exposure to light or heat.
Das an der Innenseite des Grundkörpers vorgesehene, aushärtbare Polymer ist je nach Art des Polymers direkt angebracht, oder mit einer dünnen Schutzfolie versehen. Die Schutzfolie kann verschiedene Ausführung aufzeigen. Entweder eine Schutzfolie, die vor Montage des Kabelabgangs entfernt werden muss, oder eine dünne Schutzfolie, die bei Montage des Kabelabgangs an einem Kabelabgangsstutzen zerstört wird und dadurch die Aushärtung des Polymers in Gang gesetzt wird. The curable polymer provided on the inside of the main body is directly attached, depending on the type of polymer, or provided with a thin protective film. The protective film can show various designs. Either a protective film that needs to be removed before installing the cable outlet, or a thin protective film that comes with Installation of the cable outlet is destroyed at a cable outlet nozzle and thus the curing of the polymer is set in motion.
Vorteilhaft ist das aushärtbare Polymer so an der Innenseite des Grundkörpers vorgesehen, dass es nach dem Montage des Kabelabgangs mit dem Grundkörper, dem durchgeführten Kabel und dem Kabelabgangsstutzen in Verbindung steht. Dadurch ist gewährleistet, dass eine sichere, dichte Verbindung zwischen den Bauteilen hergestellt wird. Advantageously, the curable polymer is provided on the inside of the base body so that it is connected to the base body, the cable carried out and the cable outlet connection after installation of the cable outlet. This ensures that a secure, tight connection between the components is made.
Die Verbindung von Grundkörper, Kabel und Kabelabgangsstutzen durch das ausgehärtete Polymer gewährleistet so die mechanische Fixierung des Kabels am Kabelabgangsstutzen und schützt vor dem Eindringen von Umwelteinflüssen wie Feuchtigkeit und Staub. Durch die Verwendung eines flexiblen Materials als Grundkörper bleibt trotzdem die Flexibilität des Kabelanschlusses erhalten und der Kabelabgang dient gleichzeitig als Knickschutz. The combination of body, cable and cable outlet spigot through the cured polymer thus ensures the mechanical fixation of the cable to the cable outlet spigot and protects against the ingress of environmental influences such as moisture and dust. Thanks to the use of a flexible material as the basic body, the flexibility of the cable connection is maintained and the cable outlet also serves as kink protection.
In einer besonders vorteilhaften Ausführungsform ist das aushärtbare Polymer in einer Nut vorgesehen, die an der Innenseite des Grundkörpers über dessen Umfang verläuft. Dadurch wird das Polymer gehalten und nach Aushärtung des Polymers wird eine zugsichere Verbindung zwischen dem Polymer und dem Grundkörper gewährleistet. In a particularly advantageous embodiment, the curable polymer is provided in a groove which runs on the inside of the base body over its circumference. As a result, the polymer is held and after curing of the polymer, a tensile bond between the polymer and the body is guaranteed.
Die Erfindung ist besonders vorteilhaft durch ihre leichte Handhabung, welche es ermöglicht den Kabelabgang auch feldkonfektionierbar einzusetzen. The invention is particularly advantageous due to its easy handling, which makes it possible to use the cable outlet also field-assembled.
Es muss lediglich das Kabel in den Kabelabgangsstutzen eines Gerätes, Gehäuses oder Steckverbinders eingeführt und angeschlossen werden. Der Kabelabgang wird entweder vorher - bei einteiligem Grundkörper - oder nach Anschluss des Kabels - bei mehrteiligem Grundkörper - auf dem Kabel positioniert. Durch Aufschieben des Kabelabgangs auf den Kabelabgangsstutzen wird das aushärtbare Polymer in Innenraum des Grundkörpers verteilt und mit dem Grundkörper, dem Kabel und dem Kabelabgangsstutzen in Verbindung gebracht. All you have to do is insert and connect the cable into the cable outlet of a device, housing or connector. The cable outlet is either before - in one-piece body - or after connecting the cable - in multi-part Basic body - positioned on the cable. By sliding the cable outlet on the cable outlet nozzle, the curable polymer is distributed in the interior of the body and brought into connection with the body, the cable and the cable outlet nozzle.
Nach Aushärten des Polymers ist der Kabelabgang fertig montiert. After curing of the polymer, the cable outlet is fully assembled.
Je nach eingesetztem Polymer muss vor dem Aufstecken entweder noch eine Schutzfolie vom Polymer entfernt werden. In einer bevorzugten Ausführungsform wird die Schutzfolie durch Aufschieben des Kabelabgangs auf den Kabelabgangsstutzen durch den Kabelabgangsstutzen zerstört, oder zumindest aufgerissen, wodurch sich das Polymer im Grundkörper verteilen kann. Depending on the polymer used, either a protective film must be removed from the polymer before it is plugged on. In a preferred embodiment, the protective film is destroyed by pushing the cable outlet on the cable outlet connection through the cable outlet connection, or at least tore open, whereby the polymer can be distributed in the base body.
In einer weiteren Ausführungsform hat das aushärtbare Polymer zudem eine klebende Eigenschaft um eine verbesserte Verbindung zwischen dem Kabelabgangsstutzen, dem Kabelabgang und dem Kabel zu ermöglichen. In a further embodiment, the curable polymer also has an adhesive property to allow an improved connection between the cable outlet nozzle, the cable outlet and the cable.

In part, identical reference numerals are used for the same but possibly not identical elements. Different views of the same elements could be scaled differently.
Die Figur 1 zeigt eine perspektivische Darstellung eines Kabelabgangs 1 an einem Steckverbinder 1 1. Der Kabelabgang 1 besteht aus zwei gleichartigen, hermaphroditischen Halbschalen 4a/4b die zusammen einen Grundkörper 4 bilden. Der Steckverbinder 1 1 ist in diesem Beispiel als Rundsteckverbinder ausgeführt. 1 shows a perspective view of a cable outlet 1 to a connector 1 1. The cable outlet 1 consists of two similar, hermaphroditic half-shells 4a / 4b together form a base body 4. The connector 1 1 is designed in this example as a circular connector.
Von der Rückseite des Grundkörpers 4 ist ein Kabel 2 in den Kabelabgang 1 eingeführt, welches im Steckverbinder 1 1 angeschlossen ist. Die Vorderseite des Grundkörpers 4 ist auf den Steckverbinder 1 1 aufgesteckt. From the back of the base body 4, a cable 2 is inserted into the cable outlet 1, which is connected in the connector 1 1. The front of the main body 4 is attached to the connector 1 1.
In der Figur 2 ist der Kabelabgang aus Figur 1 in einer perspektivischen Explosionsdarstellung gezeigt. Dabei sind die beiden Halbschalen 4a/4b auseinandergezogen gezeigt.

Durch die Montage der Halbschalen 4a/4b zu einem Grundkörper 4 (Figur 1 ) füllt das aushärtbare Polymer 8 den Freiraum zwischen Kabelabgangsstutzen 3, Kabel 2 und Grundkörper 4 formschlüssig aus. The cable 2, which is connected at the back to the connector 1, is inserted into the cable outlet connection 3 of the connector 1. On the inside of the half-shells 4a / 4b is a curable polymer. 8 recognizable, which is intended to lay around the cable outlet nozzle 3 and the cable 3. By mounting the half-shells 4 a / 4 b to a base body 4 (FIG. 1), the curable polymer 8 fills the free space between the cable outlet connection 3, the cable 2 and the base body 4 in a form-fitting manner.
Durch das Aushärten des Polymers 8 nach der Montage ergibt sich eine mechanisch Fixierung zwischen Kabelabgang 1 , Kabelabgangsstutzen 3 und Kabel 2. Zweckmäßig ist das aushärtbare Polymer 8 dazu so im Grundkörper 4 vorgesehen, dass es im Bereich des hinteren Endes des Kabelabgangsstutzen 3 angebracht ist. By curing the polymer 8 after assembly results in a mechanical fixation between the cable outlet 1, cable outlet 3 and cable 2. Suitably, the curable polymer 8 is provided so in the base body 4 that it is mounted in the region of the rear end of the cable outlet nozzle 3.
Die Figur 3 zeigt eine Halbschale 4a/b eines Grundkörpers 4 des Kabelabgangs 1 vereinzelt in perspektivischer Darstellung. Im vorderen, links dargestellten Bereich verfügt die Halbschale 4a/b über eine formschlüssige Öffnung 5 die dem Kabelabgangsstutzen 3 angepasst ist. Dadurch ist ein Verdrehen des Kabelabgangs 1 auf dem Kabelabgangsstutzen 3 nicht möglich. FIG. 3 shows a half shell 4a / b of a main body 4 of the cable outlet 1 in isolated form in a perspective view. In the front area shown on the left, the half-shell 4a / b has a positive opening 5 which is adapted to the cable outlet connection 3. As a result, a twisting of the cable outlet 1 on the cable outlet connection 3 is not possible.
In einer vorteilhaften Ausführung kann die formschlüssige Öffnung 5 auch als Gewinde ausgebildet sind, welches auf den Kabelabgangsstutzen 3 aufschraubbar ist. In an advantageous embodiment, the positive-locking opening 5 are also formed as a thread which can be screwed onto the cable outlet connection 3.
Der mittlere Bereich der Halbschale 4a/b ist als Kabelführung 6 ausgebildet und dient zur Führung eines Kabels 2 in dem Kabelabgang 1. Rückseitig, hier rechts dargestellt, ist der Halbschale 4a/b eine Kabeleingangsöffnung 10 angeformt. Diese Verjüngung dient zur Abdichtung des Inneren des Kabelabgangs 1 im Bereich der Kabeleinführung gegenüber der Umgebung. Je nach Materialeinsatz für die Halbschale 4a/b kann dieser Bereich, oder die gesamte Halbschale 4a/b aus flexiblem Material gebildet sein. Im Bereich zwischen der formschlüssigen Öffnung 5 und der Kabelführung 6 ist der Halbschale 4a/b an der Innenseite eine Nut 7 eingeformt, welche zur Aufnahme des aushärtbarem Polymers 8 vorgesehen ist. Die Nut 7 ist zweckmäßig so angeordnet, dass sich im Montierten Zustand von dem Kabelabgangsstutzen 3 verdeckt ist. Dadurch wird erzielt, dass der Kabelabgangsstutzen 3 der in den Kabelabgang 1 geführt wird, das aushärtbare Polymer 8 verdrängt und im Inneren des Kabelabgangs 1 verteilt. The middle region of the half-shell 4a / b is formed as a cable guide 6 and serves to guide a cable 2 in the cable outlet 1. On the back, shown here right, the half-shell 4a / b, a cable entry opening 10 is formed. This taper serves to seal the interior of the cable outlet 1 in the region of the cable entry from the environment. Depending on the material used for the half-shell 4a / b, this region, or the entire half-shell 4a / b may be formed of flexible material. In the region between the positive opening 5 and the cable guide 6, the half-shell 4a / b is formed on the inside of a groove 7, which is provided for receiving the curable polymer 8. The groove 7 is suitably arranged so that is concealed in the assembled state of the cable outlet nozzle 3. This ensures that the cable outlet nozzle 3 is guided into the cable outlet 1, displaces the curable polymer 8 and distributed in the interior of the cable outlet 1.
Die Halbschale 4a/b aus Figur 3 ist in Figur 4 noch einmal dargestellt, jedoch mit einer abgesetzt von der Halbschale 4a/b dargestellten Schutzfolie 9. Die Schutzfolie 9 ist zur Versiegelung des aushärtbaren Polymers 8 vorgesehen, dass diese nicht vor der Montage bereits aushärtet. Dabei kann die Schutzfolie 9 ein entfernbares Element sein, welches vor der Montage des Kabelabgangs 1 auf einem Kabelabgangsstutzen 3 entfernt werden muss. The half-shell 4a / b from FIG. 3 is shown once again in FIG. 4, but with a protective film 9 which is offset from the half-shell 4a / b. The protective film 9 is provided for sealing the curable polymer 8 so that it does not harden before assembly , In this case, the protective film 9 may be a removable element, which must be removed before mounting the cable outlet 1 on a cable outlet nozzle 3.
Eine vorteilhafte Ausgestaltung der Schutzfolie 9 sieht vor, diese sehr dünn auszuführen, so dass bei der Montage des Kabelabgangs 1 auf einem Kabelabgangsstutzen 3 die Schutzfolie 9 durch diesen zerstört wird und das aushärtbare Polymer 8 sich im Kabelabgang 1 verteilen kann. An advantageous embodiment of the protective film 9 provides to make this very thin, so that when installing the cable outlet 1 on a cable outlet nozzle 3, the protective film 9 is destroyed by this and the curable polymer 8 can be distributed in the cable outlet 1.
In der Figur 5 ist der Kabelabgang 1 aus Figur 1 noch einmal in teilweise geöffneter Darstellung gezeigt, wobei die eine Halbschale 4a nicht gezeigt ist um einen Blick auf das Innere des Kabelabgangs 1 zu ermöglichen. Erkennbar ist, dass der Kabelabgangsstutzen 3 in das aushärtbare Polymer 8 eingedrungen ist und dieses verdrängt hat. FIG. 5 once again shows the cable outlet 1 from FIG. 1 in a partially opened illustration, the one half shell 4a not being shown in order to allow a view of the interior of the cable outlet 1. It can be seen that the cable outlet connection 3 has penetrated into the curable polymer 8 and displaced it.
Dadurch hat sich das aushärtbare Polymer 8 aus seiner ursprünglichen Position in der Nut 7 (siehe Figur 3 und Figur 4) im gesamten Innenraum des Kabelabgangs 1 verteilt. Das aushärtbare Polymer 8 ist so von der formschlüssigen Öffnung 5 bis in die Kabelführung 6 gedrungen und hat das Kabel 2 umschlossen. Ein weiterer Kabelabgang 1 ist in der Figur 6 dargestellt. Bei dieser Ausführungsform ist der Grundkörper 4 einteilig ausgebildet. Auch hier ist das aushärtbare Polymer 8 auf der Innenseite des Grundkörpers 4 in einer Nut 7 vorgesehen. Im Unterschied zu der Ausführung der Figuren 1 bis 5 muss hier der Kabelabgangs 1 vor Montage auf das Kabel 2 gesetzte werden, bevor das Kabel 2 in den Kabelabgangsstutzen 3 eingeführt wird. Die zweiteilige Ausführung des Grundkörpers 4 aus den Figuren 1 bis 5 ermöglicht es, den Kabelabgang 1 auch noch nach Montage des Kabels 2 zu montieren. As a result, the curable polymer 8 has been distributed from its original position in the groove 7 (see FIG. 3 and FIG. 4) in the entire interior of the cable outlet 1. The curable polymer 8 has thus penetrated from the positive opening 5 into the cable guide 6 and has enclosed the cable 2. Another cable outlet 1 is shown in FIG. In this embodiment, the base body 4 is integrally formed. Again, the curable polymer 8 is provided on the inside of the base body 4 in a groove 7. In contrast to the embodiment of Figures 1 to 5 here the cable outlet 1 must be set before mounting on the cable 2, before the cable 2 is inserted into the cable outlet nozzle 3. The two-part design of the main body 4 of Figures 1 to 5 makes it possible to mount the cable outlet 1 even after installation of the cable 2.
Der Kabelabgangs 1 aus der Figur 6 ist in der Figur 7 in teilmontiertem Zustand in Schnittdarstellung gezeigt. Dargestellt ist ein Schnitt durch den Steckverbinder 1 1 und dessen Kabelabgangsstutzen 3 in welchen das Kabel 2 eingeführt ist. Der Kabelabgangs 1 ist bereits auf das Kabel 2 aufgesetzt, jedoch noch nicht auf den Kabelabgangsstutzen 3 gedrückt. The cable outlet 1 from FIG. 6 is shown partially in the assembled state in FIG. 7. Shown is a section through the connector 1 1 and its cable outlet nozzle 3 in which the cable 2 is inserted. The cable outlet 1 is already placed on the cable 2, but not yet pressed on the cable outlet nozzle 3.
Das aushärtbare Polymer 8 ist ringförmig auf der Innenseite des Grundkörpers 4 in der Nut 7 vorgesehen, wobei das Kabel 2 noch nicht in Kontakt mit dem aushärtbaren Polymer 8 steht. The curable polymer 8 is provided annularly on the inside of the base body 4 in the groove 7, wherein the cable 2 is not yet in contact with the curable polymer 8.
Die Figur 8 zeigt den fertig montierten Kabelabgang 1 auf dem Kabelabgangsstutzen 3 des Steckverbinders 1 1 ebenfalls im Schnitt. Durch eindringen des Kabelabgangsstutzen 3 in das aushärtbare Polymer 8 wurde die Schutzfolie 9 auf dem aushärtbaren Polymer 8 zerstört und das aushärtbare Polymer 8 in den Zwischenräumen zwischen Kabelabgangsstutzen 3, Grundkörper 4 und dem Kabel 2 verteilt. Figure 8 shows the fully assembled cable outlet 1 on the cable outlet nozzle 3 of the connector 1 1 also in section. By penetrating the cable outlet nozzle 3 in the curable polymer 8, the protective film 9 was destroyed on the curable polymer 8 and the curable polymer 8 in the spaces between the cable outlet nozzle 3, body 4 and the cable 2 distributed.
Je nach Stärke des eingeführten Kabels 2 streckt sich mehr oder weniger aushärtbares Polymer 8 in den Zwischenraum. Dadurch ist der erfindungsgemäße Kabelabgang 1 sehr flexibel für verschiedene Kabelstärken einsetzbar. Je dicker das Kabel 2 ist, desto mehr Material kann sich in den Zwischenraum der Kabelführung 6 erstrecken. Wenn ein dünnes Kabel 2 eingeführt ist, reicht das aushärtbare Polymer 8 aus, um eine Verbindung zwischen Kabelabgangsstutzen 3, Grundkörper 4 und dem Kabel 2 herzustellen, ohne das viel Material in die Kabelführung 6 gedrückt wird. Depending on the strength of the inserted cable 2, more or less curable polymer 8 stretches into the intermediate space. As a result, the cable outlet 1 according to the invention can be used very flexibly for different cable thicknesses. The thicker the cable 2, the more material can be in the Space between the cable guide 6 extend. When a thin cable 2 is inserted, the curable polymer 8 is sufficient to make a connection between the cable outlet 3, base 4 and the cable 2, without much material is pressed into the cable guide 6.
