Er kann glatt ausgeführt oder mit einer quer zu seiner Längsachse verlaufenden Wellung versehen sein, durch welche das HF-Kabel gut biegbar ist und in großer Länge auf eine Spule aufgewickelt werden kann. Das am Leiter des HF-Kabels angebrachte Kontaktteil dient zum Anschluß des HF-Kabels an ein anderes HF-Kabel bzw. an ein Gerät. Bei dem Kontaktteil kann es sich beispielweise um einen Steckverbinder handeln, der im Falle eines koaxialen HF-Kabels auch einen Steckerstift für den Innenleiter desselben aufweist Zur Vermeidung von Kontaktschwierigkeiten durch Korrosion oder Kurzschluß muß verhindert werden, daß Feuchtigkeit in die Verbindungsstelle gelangt Dazu muß auch der Übergang vom HF-Kabel zum Kontaktteil ausreichend abgedichtet sein. "High-frequency cables" - hereinafter referred to as "HF cables" - can be waveguides or coaxial RF cables. The conductor or outer conductor of this HF cable consists, for example, of copper. It can be made smooth or provided with a corrugation running transversely to its longitudinal axis be, through which the RF cable is easily bendable and coiled over a long length can be.

Bei dem bekannten Verfahren nach der eingangs erwähnten DE-PS 19 43 885 werden alle
Hohlräume des Verbindungselements, die bei montiertem Kontaktteil zwischen demselben und
den umschlossenen Teilen Leiter und Mantel bestehen, mit einer zähelastischen Masse ausgefüllt.
Das Kontaktteil ist dazu mit mehreren Kanälen ausgerüstet, mittels derer die Masse über den
ganzen Umfang des Leiters verteilt wird Durch die Masse ist auch der Übergang vom Mantel
zum blanken Leiter abgedichtet. Die Masse füllt dabei auch Vertiefungen aus, welche
gegebenenfalls durch eine Wellung des Leiters gegeben sind. In den Spalt zwischen Mantel und
Leiter eingedrungenem Wasser wird durch die Masse der Weg versperrt Es kann nicht in die
Verbindungsstelle zwischen Leiter und Kontaktteil gelangen. Der insgesamt zu treibende
Aufwand ist bei diesem bekannten Verbindungselement relativ hoch Es muß ein Kontaktteil mit
Kanälen verwendet werden und die zahelastische Masse muß mit einem Spezialwerkzeug in die
Hohlraume des Verbindungselements eingepreßt werdenIn the known method according to the

Dazu wird der Mantel auf einer vorgegebenen Länge vom Leiter entfernt, der danach gegebenfalls noch blank gemacht wird. Anschließend wird das buchsenförmige Kontaktteil so montiert, daß es elektrisch gut leitenden Kontakt zum Leiter hat Das in dem Zwischenraum zwischen Kontaktteil und HF-Kabel - Leiter einerseits und Mantel andererseits - befindliche Dichtmaterial vergrößert nach fertiger Montage des Kontaktteils sein Volumen derart, daß der Zwischenraum zumindest an einer Stelle umlaufend ausgefüllt ist, und zwar im kritischen Bereich am Übergang vom Leiter zum Mantel des HF-Kabels. Für das fertige Verbindungselement ist sichergestellt, daß keine Feuchtigkeit mehr an die Kontaktstelle zwischen Kontaktteil und Leiter gelangen kann This method results in a very simple assembly of the contact part, which is simple in itself can be built. The end of the RF cable is handled in the usual way. For this the Sheath removed from the conductor over a predetermined length, which may then still be bare is made. Then the socket-shaped contact part is mounted so that it is electrical This has good conductive contact with the conductor in the space between the contact part and the HF cable - Conductor on the one hand and sheath on the other hand - the existing sealing material is enlarged finished assembly of the contact part its volume such that the space at least is filled all the way around, in the critical area at the transition from the leader to the jacket of the HF cable.

Das Dichtmaterial besteht aus mindestens zwei Komponenten. Die Komponenten können so gewählt werden, daß sich eine variable Reaktionszeit ergibt. Nach Ablauf der Reaktionszeit, die für den jeweiligen Anwendungsfall eingestellt werden kann, vergrößert das Dichtmaterial sein Volumen. Dazu kann es beispielweise vor der Montage des Kontaktteils außen auf das HF-Kabel aufgebracht oder auch innen im Kontaktteil angebracht werden. Das Dichtmaterial kann aber auch so angewendet werden, daß beispielsweise nur eine seiner Komponenten auf die innere Oberfläche des Kontaktteils aufgebracht wird. Die Reaktion zur Vergrößerung des Volumens erfolgt dann durch eine zweite, in den Zwischenraum zwischen Kontaktteil und HF-Kabel einzubringende Komponente.The sealing material consists of at least two components. The components can be chosen so that there is a variable response time. After the response time, which can be adjusted for the respective application, the sealing material must be enlarged Volume. For this purpose, for example, it can be placed on the outside of the HF cable before the contact part is installed applied or attached inside the contact part. The sealing material can also be applied so that, for example, only one of its components on the inner Surface of the contact part is applied. The reaction to increase the volume is then carried out by a second, in the space between the contact part and RF cable component to be introduced.

Reaktionskomponenten ihr Volumen vergrößern. Die Basismaterialien und auch die
Reaktionskomponenten sollen so ausgewählt bzw. eingestellt werden, daß sich ein
dauerelastisches Dichtmaterial 15 ergibt. Die beiden Komponeten können kurz vor Aufbringung

Kontaktteils auf die Oberflache des HF-Kabels 1 aufgebracht wird. Die Komponenten des
Dichtmaterials 15 können auch zunächst getrennt in einem vorgefertigten Bauteil, beispielweise in
einem Ring, untergebracht sein, der bei der Montage des Verbindungselements 3 zwangsweise so
deformiert wird, daß die Komponenten zusammengebracht werden. Danach bzw. wieder mit
entsprechender Verzögerung beginnt die Volumenvergrößerung des Dichtmaterials 15. Bei dieser
Variante ist es beispielweise möglich, eine der Komponenten in Mikrokapseln anzubringen, die
