Description

Die Erfindung bezieht sich auf eine Vorrichtung zur Kontaktierung des Innenleiters eines koaxialen Hochfrequenz-Kabels, bestehend aus einem mit einem axialen Ende auf den Innenleiter aufsteckbaren metallischen Kontaktteil, dessen anderes axiales Ende einen Übergang zu einem handelsüblichen Stecksystem aufweist, bei welcher das Kontaktteil mit federnden, zur festen Anlage am Innenleiter bestimmten Kontaktlamellen und mit einer Anordnung für ein Lötmittel ausgerüstet ist (US-A-5 021 010).The invention relates to a device for contacting the inner conductor of a coaxial high-frequency cable consisting of one with an axial end on the Inner conductor attachable metallic contact part, the other axial end of a transition has a commercially available plug-in system, in which the contact part with resilient, for fixed contact on the inner conductor certain contact blades and with an arrangement for a Solder is equipped (US-A-5 021 010).

Handelsübliche Stecksysteme für koaxiale Hochfrequenz-Kabel (HF-Kabel) haben ein Kontaktteil für den meist rohrförmigen Außenleiter des HF-Kabels und ein Kontaktteil für dessen Innenleiter. Das Kontaktteil für den Innenleiter kann als Stift oder auch als Buchse ausgeführt sein. Für beide Kontaktteile eines solchen Stecksystems ist es erforderlich, daß sie eine gute elektrisch leitende Verbindung zum jeweiligen Leiter des HF-Kabels haben.Commercially available connector systems for coaxial high-frequency cables (RF cables) have one Contact part for the mostly tubular outer conductor of the HF cable and a contact part for its inner conductor. The contact part for the inner conductor can be a pin or a socket be executed. For both contact parts of such a connector system, it is necessary that they have a good electrically conductive connection to the respective conductor of the HF cable.

Bei der bekannten Steckvorrichtung nach der DE-A-2 801 037 ist das Kontaktteil für den Innenleiter des HF-Kabels ein Stift. Dieser Stift hat an seinem zur Verbindung mit dem Innenleiter bestimmten Ende eine in axialer Richtung verlaufende Bohrung. Zur Verbindung von Stift und Innenleiter wird der Stift auf den Innenleiter aufgesteckt und mit demselben verlötet. Das Lötmittel wird in die axial verlaufende Bohrung des Stiftes von der Stirnseite her eingebracht. Eine auf Dauer ausreichend feste und elektrisch gut leitende Verbindung zwischen Stift und Innenleiter ist nur gegeben, wenn genug Lötmittel in die Bohrung des Stiftes eindringt. Das ist bei dieser bekannten Steckvorrichtung nur zufällig gegeben, zumal die Bohrung des Stiftes dann schlecht zugänglich ist, wenn derselbe auf den Innenleiter aufgesteckt ist. In the known plug device according to DE-A-2 801 037, the contact part is for the Inner conductor of the RF cable a pin. This pin has on his to connect with the Inner conductor determined end of a bore running in the axial direction. For connection The pin is plugged onto the inner conductor and with the same soldered. The solder is in the axial bore of the pin from the front brought in. A connection that is sufficiently strong in the long term and that is a good electrical conductor between The pin and inner conductor are only present if enough solder penetrates the hole in the pin. This is only given by chance in this known plug-in device, especially since the bore of the Pin is difficult to access when it is attached to the inner conductor.

Aus der FR-A-2 478 882 geht ein Steckverbinder für Koaxialkabel hervor, bei dem ein Kontaktteil mit einer axial verlaufenden Bohrung auf den Innenleiter des Koaxialkabels aufgesteckt ist. Über eine radial verlaufende Bohrung kann ein Lötmittel in das Kontaktteil eingebracht werden, das zu einer festen Verbindung desselben mit dem Innenleiter des Koaxialkabels dient.From FR-A-2 478 882 a connector for coaxial cable emerges, which includes Contact part with an axially running hole on the inner conductor of the coaxial cable is attached. A solder can enter the contact part via a radially running bore be introduced, the same to a fixed connection with the inner conductor of the Coaxial cable is used.

Die eingangs erwähnte US-A-5 021 010 beschreibt eine Steckvorrichtung für Koaxialkabel, bei der zur Kontaktierung des Innenleiters desselben ein Rohrstück verwendet wird. Das Rohrstück hat nach innen weisende Kontaktlamellen und mindestens einen nach außen weisendes, die axiale Position sicherndes Federbein. Zur Zentrierung des Rohrstücks sind ein Zentrierelement und Führungselemente vorgesehen. An den Kontaktlamellen ist ein Lötmittel angebracht. In einer Ausführung dieses Rohrstückes als Stift wird gezeigt, daß das auf den Innenleiter aufsteckbare Ende des Kontaktteils als Kontakthülse ausgebildet ist, die an dem dem Übergang zu dem handelsüblichen Stecksystem entsprechenden Ende verschlossen ist und an deren anderem, offenem Ende die Kontaktlamellen angebracht sind.The above-mentioned US-A-5 021 010 describes a connector for coaxial cable, at a piece of pipe is used to contact the inner conductor of the same. The pipe piece has inward facing contact blades and at least one outward facing, the shock absorber securing the axial position. A centering element is used to center the pipe section and guide elements provided. A solder is attached to the contact blades. In a Execution of this pipe piece as a pin is shown that the pluggable onto the inner conductor end of the contact part as a contact sleeve is formed on the transition to the commercially available connector system corresponding end is closed and at the other, open end of the Contact blades are attached.

Der Erfindung liegt die Aufgabe zugrunde, die eingangs geschilderte Vorrichtung so weiterzubilden, daß ein dauerhaft guter elektrischer Kontakt zwischen Innenleiter und Kontaktteil auf einfache Weise sichergestellt ist.The invention has for its object the device described above to further develop that a permanently good electrical contact between the inner conductor and Contact part is ensured in a simple manner.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst,

  • daß im Verlauf der Kontakthülse in deren Wandung zum Durchtritt eines Lötmittels zwei Durchgangslöcher auf einander bezüglich der Achse der Kontakthülse gegenüber liegenden Seiten angebracht sind.
According to the invention, this object is achieved by
  • that in the course of the contact sleeve in the wall for passage of a solder two through holes are made on opposite sides with respect to the axis of the contact sleeve.

Der elektrisch leitende Kontakt zwischen der Kontakthülse des Kontaktteils und dem Innenleiter des HF-Kabels ist grundsätzlich bereits durch die Kontaktlamellen gesichert. Die dauerhaft feste und elektrisch leitende Verbindung zwischen beiden Teilen wird zusätzlich durch Verlöten derselben garantiert. Das Lötmittel kann dabei besonders einfach durch eines der im Verlauf der Kontakthülse vorgesehenen, leicht zugänglichen Durchgangslöcher in ausreichender Menge und kontrolliert in die Kontakthülse eingebracht werden.The electrically conductive contact between the contact sleeve of the contact part and the inner conductor of the HF cable is basically already secured by the contact blades. The permanently firm and electrically conductive connection between the two parts is additionally by soldering the same guaranteed. The solder can be particularly easily by one of the in the course of Contact sleeve provided, easily accessible through holes in sufficient quantity and be brought into the contact sleeve in a controlled manner.
