Innen- und Außenleiter des Koaxialkabels werden in der Endstellung des Bolzens zugleich kontaktiert.In a preferred embodiment, the holder is made of viscoplastic Insulating material, and the connecting bolt, which is designed as a screw bolt, has its M component area on a self-tapping thread, so that the bolt without special precautions screwed into the held coaxial cable at any point can be. The inner and outer conductors of the coaxial cable are in the end position of the bolt contacted at the same time.

Zur Erläuterung der Erfindung sind in den Figuren 1 und 2 Ausführungsbeispiele der erfindungsgemäßen Vorrichtung dargestellt und im folgenden erläutert.To explain the invention, FIGS. 1 and 2 show exemplary embodiments the device according to the invention shown and explained below.

Figur 1: Eine quaderförmige Halterung 1 besteht aus zwei in einer Symmetrieebene voneinander trennbaren Teilen 1' und 1" und weist eine Durchgangsöffnung 2 auf, in welcher das Koaxialkabel 3 liegt und mit Hilfe von Spannschrauben 4, die die beiden Halterungsteile 1' und 1" verbinden, eingespannt ist.Figure 1: A cuboid holder 1 consists of two in one Plane of symmetry separable parts 1 'and 1 "and has a through opening 2, in which the coaxial cable 3 is and with the help of tensioning screws 4, the connect the two bracket parts 1 'and 1 "is clamped.

Das Koaxialkabel 3 besteht üblicherweise aus einem metallischen Innenleiter 5, einer diesen umgebenden Isolierschicht 6, einem aus Metallgewebe bestehenden Außenleiter 7 und einem Isolierstoffmantel 8.The coaxial cable 3 usually consists of a metallic inner conductor 5, an insulating layer 6 surrounding it, consisting of a metal mesh Outer conductor 7 and an insulating jacket 8.

In dem oberen Teil 1' der Halterung 1 ist eine Bohrung 9 angebracht, die senkrecht zur Achse der Durchgangsöffnung 2 durch die Wand der aus elastischem Werkstoff bestehenden Halterung 1 führt. In diese Bohrung 9 läßt sich ein Bolzen 10 einführen und dort befestigen; beispielsweise kann der Bolzen nach Art eines Kerbstifts ausgebildet sein oder als Schraubbolzen mit Außengewinde, das mit einem in der Bohrung 9 angebrachten Innengewinde zusammenwirkt oder in bevorzugter Weise als Bolzen mit selbstschneidendem Gewinde 11, welches sich das Gegengewinde in der Innenwand der Bohrung 9 beim Eindrehen des Bolzens schafft.In the upper part 1 'of the holder 1 a hole 9 is made, the perpendicular to the axis of the passage opening 2 through the wall of the elastic Material existing bracket 1 leads. In this hole 9 can be a bolt 10 insert and fasten there; for example, the bolt in the manner of a Grooved pin or be designed as a screw bolt with an external thread with a mounted in the bore 9 cooperates internal thread or in a preferred manner as a bolt with self-tapping thread 11, which is the mating thread in the Creates inner wall of the bore 9 when screwing in the bolt.

Der Bolzen 10 selbst besteht aus einem Metallstift 12, der an seinem unteren Ende in eine Spitze 13 ausläuft.The bolt 10 itself consists of a metal pin 12 on his the lower end terminates in a tip 13.

Der Stift 12 wird koaxial von einer harten Isolierstoffschicht 14 umgeben, die bis zur Spitze 13 des Stifts 12 reicht, diese aber frei läßt.The pin 12 is coaxially covered by a hard layer of insulating material 14 surrounded, which extends to the tip 13 of the pen 12, but leaves this free.

Die Isolierstoffschicht 14 ist von einem metallischen Mantel 15 umgeben, der in einem Abstand vor der Spitze des Bolzens 10 endet, wobei der Abstand so bemessen ist, daß, wie aus der Figur erkennbar, das Ende des Mantels 15 bei eingedrehtem Bolzen in Kontakt mit dem Außenleiter 7 des Koaxialkabels 3 kommt.The insulating material layer 14 is surrounded by a metallic jacket 15, which ends at a distance in front of the tip of the bolt 10, the distance being so dimensioned is that, as can be seen from the figure, the end of the jacket 15 when screwed Bolt comes into contact with the outer conductor 7 of the coaxial cable 3.

Der so aufgebaute, an seinem unteren Ende spitz zulaufende Bolzen 10 ist an seinem oberen Ende mit Anschlußmit- teln für fortführende elektrische Leitungen versehen, hier beispielsweise mit einer Koaxialsteckverbindung 16.The bolt constructed in this way, tapering to a point at its lower end 10 is at its upper end with connection means for continuing provided electrical lines, here for example with a coaxial connector 16.

Beim Einschrauben des als Schraubbolzen ausgebildeten Bolzens 10 in die Bohrung 9 dringt das spitz zulaufende Ende des Bolzens 10, dessen Schaftlänge größer ist als die Länge der Bohrung 9, durch das MetalLgefle,ht des Außenleiters 7 und durch die Isolierschicht 6 und kontaktiert mit der Spitze 13 des Stifts 12 den Innenleiter 5 des Koaxialkabels 3, während der untere Rand des metallischen Mantels 15 mit dem Außenleiter 7 in leitende Verbindung kommt.When screwing in the bolt 10 designed as a screw bolt in the bore 9 penetrates the tapered end of the bolt 10, the length of the shaft is greater than the length of the hole 9, through the metal mesh, ht of the outer conductor 7 and through the insulating layer 6 and contacted with the tip 13 of the pin 12 the inner conductor 5 of the coaxial cable 3, while the lower edge of the metallic Sheath 15 comes into conductive connection with the outer conductor 7.

Bei Koaxialkabeln, deren Isolierschicht zwischen Innen- und Außenleiter so weich ist, daß beim Einschrauben des Bolzens 10 eine Verdrängung des Innenleiters aus seiner zentrischen Lage befürchtet werden muß, kann, wie Figur 2 zeigt, in dem unteren Teil 1 der Halterung 1 koaxial zur Bohrung 9 im oberen Teil 1' eine Ausnehmung 17 vorgesehen werden, in der ein radial nach innen in die Durchgangsöffnung 2 ragender Dorn 18 befestigt ist; dieser besteht aus einem harten Material, beispielsweise einem isolierten Metallstift und dringt beim Zusammensetzen der Halterung 1 durch die äußeren Schichten des Koaxialkabels 3 bis zur Anlage an den Innenleiter 5.In the case of coaxial cables, the insulating layer between the inner and outer conductor is so soft that when the bolt 10 is screwed in, the inner conductor is displaced must be feared from its central position, as Figure 2 shows, in the lower part 1 of the holder 1 coaxially to the bore 9 in the upper part 1 'a recess 17 are provided, in which a radially inwardly projecting into the through opening 2 Mandrel 18 is attached; this consists of a hard material, for example an insulated metal pin and penetrates when the holder 1 is assembled the outer layers of the coaxial cable 3 up to the point of contact with the inner conductor 5.

Anstelle des Dorns 18 in der Ausnehmung 17 kann die Halterung 1 auch aus zwei symmetrischen Teilen 1' mit Bohrungen 9 zusammengesetzt sein, wobei in dem unteren Teil dann ein zweiter Bolzen 10 als ein Gegenlager eingedreht werden kann, wobei der Bolzen in diesem Falle keine Anschlußmittel an seinem äußeren Ende aufzuweisen braucht.Instead of the mandrel 18 in the recess 17, the holder 1 can also be composed of two symmetrical parts 1 'with holes 9, wherein in the lower part then a second bolt 10 can be screwed in as a counter bearing can, in which case the bolt has no connection means at its outer end needs to have.
