Here, the housing (2) which is integral with the articulation element (4) consists of two half shells (5,6) which are connected to one another by means of a film hinge (8) so as to be capable of being folded closed and folded open. <IMAGE>

Description

Die vorliegende Erfindung betrifft eine Knickschutzvorrichtung aus Kunststoff für Kabel-Stecker insbesondere für EDV-Anlagen u. dgl., wo das aus dem Steckergehäuse austretende Kabel durch ein sich in Kabelerstreckung verjüngendes, durch Materialausnehmungen nach mindestens einer Seite hin elastisch biegbares Gelenkstück geführt ist, an dem sich ein zum Umschliessen eines Teiles eines Steckers bestimmtes Gehäuse anschliesst.The present invention relates to an anti-kink device made of plastic for cable connectors, in particular for computer systems and. Like. Where the cable emerging from the connector housing is guided by a joint piece tapering into the cable extension, elastically bendable through material recesses towards at least one side, to which a housing intended for enclosing a part of a connector is connected.

Knickschutzvorrichtungen der vorgenannten Art an Kabel-Stecker sind üblich, um Kabelbrüche infolge Abbiegens mit zu geringem Radius zu verhindern. Dies ist insbesondere von grosser Bedeutung, an Kabel-Stecker für Kommunikations-Netze, wie EDV-Anlagen, wo Kleinststecker mit einer Vielzahl dünnster Kupferdrähte oder Glasfasern die weltweit standardisierten Anschlussnormen für Tele- und Datenkommunikationsanschlüsse gewährleisten.Kink protection devices of the aforementioned type on cable plugs are common in order to prevent cable breaks as a result of bending with an insufficient radius. This is particularly from of great importance to cable plugs for communication networks, such as EDP systems, where miniature plugs with a multitude of thinnest copper wires or glass fibers guarantee the globally standardized connection standards for tele and data communication connections.

Knickschutzvorrichtungen dieser Art werden entweder mit Stecker und Kabel vergossen oder von der Kabelseite her nach der Verdrahtung auf den Stecker aufgeschoben und verklinkt oder verklebt.Anti-kink devices of this type are either cast with plugs and cables or are pushed onto the plug from the cable side after wiring and latched or glued.

In beiden Fällen wird der Stecker auf Anschlussfehler hin oder für Anschlussänderungen unbrauchbar und muss samt Zuleitung und Knickschutzvorrichtung ausgewechselt werden.In both cases, the connector becomes unusable due to connection errors or for connection changes and must be replaced together with the supply line and kink protection device.

Es ist deshalb Aufgabe der vorliegenden Erfindung, eine Knickschutzvorrichtung der vorgenannten Art zu schaffen, die sich an Ort aufbringen lässt und beliebig wiederentfernbar und austauschbar ist.It is therefore an object of the present invention to provide an anti-kink device of the aforementioned type which can be applied on site and can be removed and replaced as required.

Dies wird erfindungsgemäss dadurch erreicht, dass das mit dem Gelenkstück einstückige Gehäuse aus zwei, vorzugsweise über ein Filmscharnier miteinander zu- und aufklappbar verbundene Halbschalen besteht.This is achieved according to the invention in that the housing, which is integral with the joint piece, consists of two half-shells, which are preferably connected to one another by a film hinge and can be swung open.

Diese Massnahmen gestatten nun nach Bedarf ein beliebiges Ausrüsten der infrage stehenden Stecker an Ort mit einer Knickschutzvorrichtung, die, etwa zur farbigen Anschlussmarkierung, beliebig ausgewechselt werden kann.These measures now allow the connectors in question to be equipped on site with an anti-kink device, which can be replaced as required, for example for colored connection marking.

Für eine leichte Handhabung bei sicherer Verriegelung der beiden Halbschalen kann die Ausgestaltung des Erfindungsgegenstandes vorzugsweise so sein, dass die geschlossenen Halbschalen durch lösbare Laschenmittel verriegelbar sind.For easy handling with secure locking of the two half-shells, the design of the subject matter of the invention can preferably be such that the closed half-shells can be locked by releasable tab means.

Eine beispielsweise Ausführungsform des Erfindungsgegenstandes ist nachfolgend anhand der Zeichnung näher erläutert. Es zeigen:

Die Knickschutzvorrichtung gemäss Fig. 1 umfasst ein, sich in Kabelerstreckung verjüngendes, durch Materialausdehnungen 5 (Fig. 2) elastisch biegbares, ein Stecker-Kabel 3 umschliessbares Gelenkstück 4, an welchem sich steckerseitig ein, einen Stecker 1 umschliessendes Gehäuse 2 anschliesst.1 comprises a joint piece 4, which tapers into the extension of the cable and is elastically bendable due to material expansions 5 (FIG. 2), and which can be enclosed by a plug cable 3 and to which a housing 2 is connected on the plug side and encloses a plug 1.

Diese ansich bekannte Knickschutzvorrichtung besteht vorzugsweise aus Kunststoff.This known anti-kink device is preferably made of plastic.

Diese Knickschutzvorrichtung wird vorzugsweise an geschirmten AMP- und DDKRJ45-Stecker 1 verwendet.This kink protection device is preferably used on shielded AMP and DDKRJ45 connectors 1.

Erfindungsgemäss ist nun gemäss den Fig. 2 bis 5 das mit dem Gelenkstück 4 einstückige Gehäuse 2 aus zwei Halbschalen 6,7 gebildet, die hier über ein Filmscharnier 8 miteinander zu- und aufklappbar verbunden sind, was ein beliebiges zerstörungsfreies Auswechseln gestattet.According to the invention, according to FIGS. 2 to 5, the housing 2, which is integral with the joint piece 4, is formed from two half-shells 6, 7, which here are connected to one another by means of a film hinge 8 and can be swung open, which allows any non-destructive replacement.

Hierbei sind die geschlossenen Halbschalen 6,7 durch lösbare Laschenmittel verriegelbar. Diese Laschenmittel umfassen zunächst eine angeformte zungenartige Lasche 18 am leiterseitigen Ende der Knickschutzvorrichtung, die bei geschlossenen Halbschalen 6,7 um die eine Halbschale herumgeführt und an einem Widerhaken 18' eingehakt wird. Ferner ist am steckerseitigen Ende eine T-Zunge 19 angeformt, die in geschlossenem Zustand eine Gegennut 19' untergreift.The closed half-shells 6, 7 can be locked by releasable tab means. These tab means initially include an integrally formed tongue-like tab 18 on the conductor-side end of the anti-kink device, which, when the half-shells 6, 7 are closed, are guided around the one half-shell and hooked onto a barb 18 '. Furthermore, a T-tongue 19 is formed on the plug-side end, which engages under a counter groove 19 'in the closed state.

Ferner ist an einer Halbschale 6 oder 7 ein Zentrierstift 10 vorgesehen, welcher bei geschlossenem Gehäuse 6,7 in eine Gegenbohrung 10' in der anderen Halbschale eingreift.Furthermore, a centering pin 10 is provided on a half-shell 6 or 7, which engages in a counterbore 10 ′ in the other half-shell when the housing 6, 7 is closed.

Die erfindungsgemässe Knickschutzvorrichtung kann in beliebigen Farben gestaltet sein, wobei zudem die flächige Ausgestaltung insbesondere des Gehäuseteiles 2 die Anbringung von Etiketten gestattet.The anti-kink device according to the invention can be designed in any color, and in addition the flat design, in particular of the housing part 2, allows the attachment of labels.
