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 (DE-OS 28 01 037).The invention relates to a device for contacting the inner conductor of a coaxial high-frequency cable, consisting of a metallic contact part which can be plugged onto the inner conductor with an axial end, the other axial end of which has a transition to a commercially available plug-in system (DE-OS 28 01 037) .

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 plug systems for coaxial high-frequency cables (HF cables) have a 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 designed as a pin or as a socket. For both contact parts of such a plug-in system, it is necessary that they have a good electrically conductive connection to the respective conductor of the RF cable.

Bei der bekannten Steckvorrichtung nach der eingangs erwähnten DE-OS 28 01 037 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-OS 28 01 037 mentioned at the beginning, the contact part for the inner conductor of the HF cable is a pin. At its end intended for connection to the inner conductor, this pin has a bore running in the axial direction. To connect the pin and the inner conductor, the pin is plugged onto the inner conductor and soldered to it. The solder is introduced into the axial bore of the pin from the front. A permanent and sufficiently good electrical connection between the pin and the inner conductor is only possible if enough solder penetrates the hole in the pin. This is only given by chance in this known plug-in device, especially since the hole in the pin is difficult to access when it is plugged onto the inner conductor.

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

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst,

  • - daß das auf den Innenleiter aufsteckbare Ende des Kontaktteils als Kontakthülse ausgebildet ist, an deren offenem Ende federnde, zur festen Anlage am Innenleiter bestimmte Kontaktlamellen angebracht sind und
  • - daß im Verlauf der Kontakthülse mindestens ein Durchgangsloch zum Durchtritt eines Lötmittels in deren Wandung angebracht ist.
According to the invention, this object is achieved by
  • - That the end of the contact part that can be plugged onto the inner conductor is designed as a contact sleeve, at the open end of which resilient, fixed contact plates are attached to the inner conductor and
  • - That in the course of the contact sleeve at least one through hole is made for the passage of a solder in the wall thereof.

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 das im Verlauf der Kontakthülse vorgesehene, leicht zugängliche Durchgangsloch 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 in principle already secured by the contact lamellae. The permanently firm and electrically conductive connection between the two parts is also guaranteed by soldering them. The solder can be introduced in a particularly simple and controlled manner into the contact sleeve in a sufficient amount through the easily accessible through hole provided in the course of the contact sleeve.

  • Fig. 1 shows the end of an RF cable equipped with a plug connection.
  • 2 and 3 two different embodiments of the contact sleeve of the contact part for the inner conductor.

Die Steckverbindung nach Fig. 1 besteht aus einer Buchse 1, die mit dem Außenleiter des HF-Kabels 2 in geeigneter Weise elektrisch leitend verbunden ist. An dem von umgebenden Schichten befreiten Innenleiter 3 des HF-Kabels 2 ist ein Kontaktteil 4 elektrisch leitend angebracht. Das Kontaktteil 4 weist dazu eine Kontakthülse 5 auf, in welche das Ende des Innenleiters 3 eingesteckt ist. Es ist im dargestellten Ausführungsbeispiel als Steckerstift ausgeführt. Als Kontaktteil 4 könnte aber auch eine Steckbuchse eingesetzt sein. Der Aufbau der Kontakthülse 5 geht in genauerer Darstellung aus den Fig. 2 und 3 hervor.1 consists of a socket 1, which is connected to the outer conductor of the RF cable 2 in a suitable manner in an electrically conductive manner. A contact part 4 is attached in an electrically conductive manner to the inner conductor 3 of the HF cable 2 that is freed from surrounding layers. For this purpose, the contact part 4 has a contact sleeve 5, into which the end of the inner conductor 3 is inserted. It is designed as a plug pin in the illustrated embodiment. A plug socket could also be used as the contact part 4. The structure of the contact sleeve 5 is shown in more detail in FIGS. 2 and 3.

Diese sind gemäß Fig. 2 im Innern der Kontakthülse 5 angeordnet. Sie können nach Fig. 3 auch in axialer Richtung über die Kontakthülse 5 hinausragend an derselben angebracht sein. Die Kontaktlamellen 6 sind so dimensioniert und angeordnet, daß sie fest am Innenleiter 3 anliegen.The contact sleeve 5 belonging to the contact part 4 has resilient contact blades 6 at its end to be plugged onto the inner conductor 3. 2 are arranged inside the contact sleeve 5. According to FIG. 3, they can also be attached to the contact sleeve 5 in an axial direction projecting thereon. The contact lamellae 6 are dimensioned and arranged in such a way that they rest firmly against the inner conductor 3.

Die elektrisch leitende Verbindung zwischen Kontakthülse 5 und Innenleiter 3 ist an sich schon durch die Kontaktlamellen 6 gewährleistet. Sie wird durch eine zusätzliche Lötverbindung zwischen beiden Teilen garantiert. Dazu sind in der Wandung der Kontakthülse 5 zwei Durchgangslöcher 7 angebracht, durch welche ein Lötmittel in die Kontakthülse 5 eingebracht werden kann. Die beiden Durchgangslöcher 7 liegen einander bezüglich der Achse der Kontakthülse 5 direkt gegenüber. Sie können aber auch andere Positionen haben. Es soll mindestens ein Durchgangsloch 7 in der Wandung der Kontakthülse 5 angebracht sein. Es können aber auch mehr als zwei Durchgangslöcher sein.The electrically conductive connection between the contact sleeve 5 and the inner conductor 3 is already guaranteed by the contact blades 6. It is guaranteed by an additional solder connection between the two parts. For this purpose, two through holes 7 are made in the wall of the contact sleeve 5, through which a solder can be introduced into the contact sleeve 5. The two through holes 7 lie directly opposite one another with respect to the axis of the contact sleeve 5. But you can also have other positions. At least one through hole 7 should be made in the wall of the contact sleeve 5. However, there can also be more than two through holes.
