Die beispielsweise aus der DE 103 06 053 A1 bekannten BNC-Verbinder (Bayonet Navy Connector) sind für HF-Verbindungen bekannt und entsprechen in Ihren Abmessungen einem vorgegebenen BNC-Standard. Ein besonderer Vorteil von BNC-Verbindern ist deren einfache Anwendbarkeit. Der BNC-Stecker wird in die BNC-Buchse geschoben und mit einer einfachen Vierteldrehung elektrisch und mechanisch verbunden. Diese einfache Handhabbarkeit hat jedoch eingeschränkte elektrische Eigenschaften zur Folge. So ist die Übertragungsbandbreite bei HF- Anwendungen auf ca. 3 GHz beschränkt. In der Präzisionsmesstechnik, wie beispielsweise bei Netzwerkanalysern oder Hochfrequenzoszilloskopen sind jedoch bei Steckverbindern an Signalein- bzw. Signalausgängen Bandbreiten von bis zu 20 GHz notwendig. Dies führt bisher dazu, dass Steckverbinder an Messeingän- gen von Präzisionsmessinstrumenten speziell ausgestaltet sind, um die hohen Anforderungen an die elektrischen Eigenschaften zu erfüllen. Wollte man jedoch für Anwendungen mit geringeren Anforderungen an die Messgenauigkeit eine kostengünstige Messausrüstung verwenden, die BNC-Verbinder benutzt, so sind bisher kostenintensive Umrüstebenen für Gerätebuchsen notwendig, die eine Ver- bindung der BNC-Verbinder der kostengünstige Messausrüstung an die speziellen Gerätebuchsen der Präzisionsmessinstrumente adaptieren.The BNC connectors known from DE 103 06 053 A1 (Bayonet Navy Connector) are known for HF connections and correspond in their dimensions to a predetermined BNC standard. A particular advantage of BNC connectors is their ease of use. The BNC plug is pushed into the BNC socket and connected electrically and mechanically with a simple quarter turn. However, this ease of handling results in limited electrical properties. So the transmission bandwidth at HF Applications limited to about 3 GHz. However, in precision metrology, such as network analyzers or high-frequency oscilloscopes, bandwidths of up to 20 GHz are required for connectors on signal inputs or outputs. So far, this has led to connectors on measuring inputs of precision measuring instruments being specially designed to meet the high demands on electrical properties. However, for low-cost measurement applications, where low-cost measurement equipment using BNC connectors is required, expensive bushing conversion levels have been required to adapt the BNC connectors of cost-effective metering equipment to the dedicated instrumentation jacks of the precision gauges ,

Art derart dahingehend zu verbessern, dass die- ser universell einsetzbar und sowohl mit hochpräzisen Messinstrumenten mit hohen Anforderungen an die elektrischen Eigenschaften als auch mit herkömmlichen Messinstrumenten mit geringeren Anforderungen an die elektrischen Eigenschaften verwendbar ist, ohne dass dazu aufwändige Adapter notwendig sind.The invention has for its object to provide a Koaxialbuchsenverbinder or Koaxialsteckerverbinder the o.g. To improve such a way that it can be used universally and with both high-precision measuring instruments with high demands on the electrical properties as well as with conventional measuring instruments with lower demands on the electrical properties can be used without the need complicated adapter are necessary.
Diese Aufgabe wird erfindungsgemäß durch einen Koaxialbuchsenverbinder der o.g. Art mit den in Anspruch 1 gekennzeichneten Merkmalen und durch einen Koaxialsteckerverbinder der o.g. Art mit den in Anspruch 5 gekennzeichneten Merkmalen gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den weiteren Ansprüchen beschrieben.This object is achieved by a Koaxialbuchsenverbinder o.g. A type having the features characterized in claim 1 and by a coaxial connector of the above-mentioned. Art solved with the features characterized in claim 5. Advantageous embodiments of the invention are described in the further claims.
Bei einem Koaxialbuchsenverbinder der o.g. Art ist es erfindungsgemäß vorgesehen, dass wenigstens zwischen der elektrischen und mechanischen Referenzebene einerseits und dem zweiten Ende des Koaxialbuchsenverbinders andererseits das Innenleiterteil und das Außenleiterteil über wenigstens einen vorbestimmten Abschnitt zwischen sich eine 7mm-Koaxialleitung ausbilden, bei der ein Innendurchmesser eines Außenleiters des Außenleiterteils 7 mm und ein Außendurchmesser eines Innenleiters des Innenleiterteils 3,05 mm beträgt und zwischen Innen- und Außenleiter Luft als Dielektrikum vorhanden ist. Dies hat den Vorteil, dass ein BNC-kompatibler Koaxialbuchsenverbinder zur Verfügung steht, auf den neben herkömmlichen BNC-Steckern auch besonders an- gepasste Koaxialsteckerverbinder aufgesteckt werden können, die zusammen mit dem erfindungsgemäßen Koaxialbuchsenverbinder eine erhöhte Übertragungs- bandbreite für Hochfrequenz zur Verfügung stellen. Mit anderen Worten stellt der neuartige Koaxialbuchsenverbinder einen bzgl. der HF-Übertragung hochwertigen Verbinder dar, der im Falle, dass für eine Anwendung eine niedrigere Übertragungsbandbreite ausreichend ist, bzgl. herkömmlicher BNC-Stecker mit geringerer Bandbreite abwärtskompatibel ist. Mit der 7mm-Koaxialleitung weist der Koaxial- buchsenverbinder eine hochpräzise herstellbare HF-Leitung auf, die bei Kombination mit einem entsprechenden Koaxialsteckerverbinder eine hohe elektrische Qualität der Steckverbindung mit hoher Übertragungsbandbreite für HF-Signale bis zu 20 GHz zur Verfügung stellt. Gleichzeit sind für 7 mm-Koaxialleitungen bereits entsprechende Messstandards vorhanden, die verwendet werden können.In a Koaxialbuchsenverbinder of the type mentioned above, it is provided according to the invention that at least between the electrical and mechanical reference plane on the one hand and the second end of the Koaxialbuchsenverbinders on the other hand, the inner conductor part and the outer conductor part form at least a predetermined section between them a 7mm coaxial line, wherein an inner diameter of a Outer conductor of the outer conductor part 7 mm and an outer diameter of an inner conductor of the inner conductor part is 3.05 mm and between the inner and outer conductor air is present as a dielectric. This has the advantage that a BNC-compatible coaxial socket connector is available, to which, in addition to conventional BNC connectors, particularly adapted coaxial plug connectors can be plugged, which together with the coaxial socket connector according to the invention provide an increased transmission bandwidth for radio frequency. In other words, the novel coaxial jack connector provides a high-quality connector for RF transmission, which is backwards compatible in the case that a lower transmission bandwidth is sufficient for an application with respect to conventional lower bandwidth BNC connectors. With the 7mm coaxial cable, the coaxial socket connector features a high-precision producible RF cable that, when combined with a corresponding coaxial connector, provides a high electrical quality connector with high transmission bandwidth for RF signals up to 20 GHz. At the same time, corresponding measurement standards are already available for 7 mm coaxial cables, which can be used.
Ein zerstörungsfreies Stecken bei gleichzeitig gutem elektrischem Kontakt am Innenleiter erzielt man dadurch, dass am ersten Ende des Innenleiterteils eine In- nenleiterbuchse angeordnet ist, die bzgl. des Innenleiterteils axial verschiebbar ist, wobei zwischen der Innenleiterbuchse und dem Innenleiterteil eine Feder derart angeordnet ist, dass diese Feder auf die Innenleiterbuchse eine Kraft in Richtung des ersten Endes des Koaxialbuchsenverbinders ausübt.Non-destructive plugging with simultaneously good electrical contact on the inner conductor is achieved by arranging an inner conductor bushing at the first end of the inner conductor part, which is axially displaceable with respect to the inner conductor part, wherein a spring is arranged between the inner conductor bushing and the inner conductor part this spring exerts a force on the inner conductor socket in the direction of the first end of the coaxial socket connector.

Art ist es erfindungsgemäß vorgesehen, dass das Innenleiterteil und das Außenleiterteil des Koaxialsteckerverbinders derart ausgebildet sind, dass diese bei in den Koaxialbuchsenverbinder eingestecktem Koaxialsteckerverbinder das Außenleiterteil und das Innenleiterteil des Koaxialbuchsenverbinders derart ergänzen, dass wenigstens in dem Bereich zwi- sehen der elektrischen und mechanischen Referenzebene und dem ersten Ende des Koaxialbuchsenverbinders eine 7mm-Koaxialleitung ausgebildet ist, bei der ein Innendurchmesser eines Außenleiters des Außenleiterteils 7 mm und ein Außendurchmesser eines Innenleiters des Innenleiterteils 3,05 mm beträgt und zwi- sehen Innen- und Außenleiter Luft als Dielektrikum vorhanden ist.In a Koaxialsteckerverbinder of the type mentioned above, it is provided according to the invention that the inner conductor part and the outer conductor part of Koaxialsteckerverbinders are formed such that they complement in Koaxialbuchsenverbinder plugged coaxial connector the outer conductor part and the inner conductor part of Koaxialbuchsenverbinders such that at least in the range between see the electrical and mechanical reference plane and the first end of the Koaxialbuchsenverbinders a 7mm coaxial line is formed, in which an inner diameter of an outer conductor of the outer conductor part 7 mm and an outer diameter of an inner conductor of the inner conductor part is 3.05 mm and see between inner and outer conductor air as a dielectric is present.
Dies hat den Vorteil, dass eine HF-Steckverbindung mit besonders guten elektrischen Eigenschaften hoher Übertragungsbandbreite für HF-Signale bis zu 20 GHz zur Verfügung steht. Aufgrund der 7 mm-Koaxialleitungen können bereits vorhan- dene Messstandards verwendet werden.This has the advantage that an HF connector with particularly good electrical properties of high transmission bandwidth for HF signals up to 20 GHz is available.
