Description

Aus Gründen der Gewichtsersparnis und des Fortfalls eines besonderen Oberflächen-Berührungsschut-.zes geht man seit einiger Zeit mehr und mehr dazu über, die mannigfachen Fernmeldekabelgarnituren, wie z. B. Endverschlüsse, anstatt aus Metallen, aus glasfaserverstärkten Kunststoffen, insbesondere Polyester-Preßmassen, herzustellen. Solche Kabelgarnituren werden z. B. in DT-Gbm 1 828 740 und DT-Gbm 1 897 927 beschrieben.For reasons of weight saving and the elimination of a special surface contact protection .ze For some time now one has been moving more and more to the various telecommunication cable accessories, such as z. B. Terminations, instead of metal, made of glass fiber reinforced plastics, especially polyester molding compounds, to manufacture. Such cable accessories are z. B. in DT-Gbm 1 828 740 and DT-Gbm 1 897 927 described.

Nun neigen bekanntlich alle glasfaserverstärkten Kunststoffe auf Grund der ausgesprochen extremen thermischen Ausdehnungskoeffizienten unter klimatischen Beanspruchungen zu mehr oder weniger starken Alterserscheinungen, die sich ganz besonders hinsichtlich der Durchlässigkeit von Gasen und Dämpfen auswirken, und zwar ganz besonders stark, wenn, wie es vorzugsweise bei den ungesättigten Polyestern der FaIi ist, zu den vorwiegend physikalischen Veränderungen des Verbundsystems (Glasfaser/Harz) noch physikalische (Verflüchtigung von Styrol) und chemische (hydrolytischer Abbau in steigendem Maße unterstützt durch aus Glaskomponente frei werdendem Alkali) Verwitterungserscheinungen hinzukommen, die auf längere Sicht die daraus gefertigten Teile u. U. derart undicht zu machen vermögen, daß sogar Wasser kapillar durchzutreten vermag.Now, as is well known, all glass fiber reinforced plastics tend due to their extremely extreme thermal expansion coefficient under climatic stress to more or less strong Signs of age, which have a particular effect on the permeability of gases and vapors, and particularly strongly if, as is preferably the case with the unsaturated polyesters of the FaIi is, in addition to the predominantly physical changes in the composite system (glass fiber / resin), physical changes (Volatilization of styrene) and chemical (hydrolytic degradation to an increasing extent supported by alkali released from glass components) In view of this, the parts manufactured therefrom may, under certain circumstances, be able to leak in such a way that even water can penetrate through capillary action able.

Bei der Verwendung für Fernmeldekabelgarnituren ist eine unverändert hohe Dichtigkeit, vor allem gegen Wasser und Wasserdampf (Luftfeuchtigkeit), unbedingt erforderlich, wie sie z. B. von Polyolefinen und ihren Derivaten gewährleistet wird. Diese können jedoch aus Gründen ungenügender Festigkeit für viele dieser Garnituren nicht ohne weiteres verwendet werden.When used for telecommunication cable sets, there is an unchanged high level of tightness, especially against Water and water vapor (humidity), absolutely necessary, as they are z. B. of polyolefins and their Derivatives is guaranteed. However, for reasons of insufficient strength, these can be used for many of these sets cannot be used out of hand.

Die Erfindung beruht auf der Erkenntnis, daß man auch bei Fernmeldekabelgarnituren mit Festigkeitsträgern aus glasfaserverstärkten Kunststoffen die hohe Dichtkeit und Alterungsbeständigkeit der Kunststoffe voll ausnutzen kann, wenn der Festigkeitsträger direkt oder unter Verwendung von Haftvermittlern außenseitig und/oder innenseitig mit vorzugsweise elastisch-flexiblen Kunststoffen hoher Gasdichtheit und Alterungsbeständigkeit beschichtet ist.
Als vorzugsweise Beschichtungs-Kunststoffe können Hochpolymere, z. B. Gummi, Polysulfide und ähnliche Elastomere, insbesondere aber Polyolefine oder deren Derivate, z. B. Polyäthylen, Copolymere des Äthylens und Propylens oder chlorsulfoniertes Polyäthylen verwendet werden.
The invention is based on the knowledge that the high tightness and aging resistance of the plastics can also be fully exploited in telecommunication cable sets with reinforcements made of glass fiber reinforced plastics if the reinforcement is made directly or with the use of adhesion promoters on the outside and / or on the inside with preferably elastic-flexible plastics with high gas tightness and aging resistance is coated.
High polymers, e.g. B. rubber, polysulfides and similar elastomers, but especially polyolefins or their derivatives, e.g. B. polyethylene, copolymers of ethylene and propylene or chlorosulfonated polyethylene can be used.

Die Beschichtung kann in an sich bekannter Weise durch Spritzen, Tauchen od. dgl. erfolgen.The coating can be carried out in a manner known per se by spraying, dipping or the like.
