Description

Die Erfindung betrifft einen Koaxialsteckverbinder und insbesondere einen gemäß der DIN 47 223 ausgebildeten Koaxialsteckverbinder.The invention relates to a coaxial connector and in particular to a coaxial connector designed according to DIN 47 223.

In der DIN 47 223 ist ein Koaxialsteckverbinder normiert, dessen Innenleiter einen Außendurchmesser von ca. 7 mm und dessen Außenleiter einen Innendurchmesser von ca. 16 mm aufweist. Koaxialsteckverbinder gemäß der DIN 47 223 werden daher auch als 7/16-Koaxialsteckverbinder bezeichnet. Durch das konkrete Durchmesserverhältnis wird mit Luft als Dielektrikum zwischen den steckseitigen Enden des Innen- und des Außenleiters ein Wellenwiderstand von ca. 50 Ω erreicht.A coaxial connector is standardized in DIN 47 223, the inner conductor of which has an outer diameter of approximately 7 mm and the outer conductor of which has an inner diameter of approximately 16 mm. Coaxial connectors according to DIN 47 223 are therefore also referred to as 7/16 coaxial connectors. Due to the concrete diameter ratio, a wave resistance of approx. 50 Ω is achieved with air as the dielectric between the ends of the inner and outer conductors.

Ein gemäß der DIN 47 223 ausgebildeter Koaxialsteckverbinder in Form eines Koaxialsteckers weist steckseitig ein stiftförmiges Ende des Innenleiters auf, das in ein entsprechendes buchsenförmiges Ende des Innenleiters eines als Koaxialkupplers ausgebildeten Koaxialsteckverbinders eingesteckt wird. Der Außenleiter des Koaxialsteckers kontaktiert dabei den Außenleiter des Koaxialkupplers in sowohl axialer als auch radialer Richtung, indem das rohrförmige Ende des Außenleiters des Koaxialsteckers gegen einen ringförmigen Absatz gedrückt wird, der von der Innenseite des Außenleiters des Koaxialkupplers ausgebildet wird. Die hierfür erforderliche Axialkraft wird durch eine Überwurfmutter aufgebracht, die drehbar auf einem der Steckverbinder gelagert ist und auf ein an dem entsprechenden anderen Steckverbinder vorgesehenes Außengewinde aufgeschraubt wird. Gleichzeitig dient diese Verschlussverschraubung der Sicherung der Koaxialsteckverbindung gegen ungewolltes Lösen. Ein solcher Koaxialsteckverbinder ist beispielsweise aus der Die DE 43 00 243 C1 bekannt.A coaxial connector designed in accordance with DIN 47 223 in the form of a coaxial connector has a pin-shaped end of the inner conductor on the plug side, which is inserted into a corresponding socket-shaped end of the inner conductor of a coaxial connector designed as a coaxial coupler. The outer conductor of the coaxial connector contacts the outer conductor of the coaxial coupler in both the axial and radial directions by pressing the tubular end of the outer conductor of the coaxial connector against an annular shoulder which is formed by the inside of the outer conductor of the coaxial coupler. The axial force required for this is applied by a union nut, which is rotatably mounted on one of the connectors and is screwed onto an external thread provided on the corresponding other connector. At the same time, this screw connection is used to secure the coaxial connector against unintentional loosening. Such a coaxial connector is, for example, from Die DE 43 00 243 C1 known.

Um eine Intermodulation im Bereich der Koaxialsteckverbindung möglichst gering zu halten, werden für diese teilweise äußerst geringe Störabstände vorgeschrieben, die nur dadurch erreicht werden können, dass die beiden Koaxialsteckverbinder einer Koaxialsteckverbindung unter sehr hohen Axialkräften gegeneinander gedrückt werden. Beispielsweise ist es bei der Verkabelung von Mobilfunk-Basisstationen erforderlich, die Überwurfmutter einer solchen Koaxialsteckverbindung mit einem Drehmoment von bis zu 35 Nm anzuziehen, um den geforderten Störabstand zu erreichen. Eine entsprechende funktionssichere Montage einer solchen Koaxialsteckverbindung kann daher lediglich durch den Einsatz eines ausreichend groß dimensionierten Drehmomentschlüssels sichergestellt werden, was mit einem nicht unerheblichen Aufwand verbunden ist.In order to keep intermodulation in the area of the coaxial connector as low as possible, extremely low signal-to-noise ratios are prescribed for them can only be achieved in that the two coaxial connectors of a coaxial connector are pressed against each other under very high axial forces. For example, when cabling mobile radio base stations, it is necessary to tighten the union nut of such a coaxial connector with a torque of up to 35 Nm in order to achieve the required signal-to-noise ratio. A corresponding functionally reliable installation of such a coaxial connector can therefore only be ensured by using a sufficiently large torque wrench, which is associated with a not inconsiderable effort.

Aus der US 6,837,754 B1 sind zudem Adapterelemente, mit denen mehrere Kabel gebündelt an einen Anschluss eines Transformators angeschlossen werden, bekannt. Jeder dieser Anschlüsse umfasst einen ringförmigen Kupplungskörper, gegen den zur Herstellung des Anschlusses ein ringförmiger Kupplungskörper des dazugehörigen Adapterelements verspannt wird. Die Kontaktflächen der Kupplungskörper sind mit Vorsprüngen und Vertiefungen versehen, in die entsprechende Vorsprünge bzw. Vertiefungen des Gegenelements eingreifen. Dadurch soll die Kontaktfläche zwischen den beiden Kontaktkörpern möglichst groß ausgebildet werden.From the US 6,837,754 B1 are also known adapter elements with which several cables are connected in bundles to a connection of a transformer. Each of these connections comprises an annular coupling body against which an annular coupling body of the associated adapter element is clamped in order to produce the connection. The contact surfaces of the coupling bodies are provided with projections and depressions into which corresponding projections or depressions of the counter element engage. This is intended to make the contact area between the two contact bodies as large as possible.

Aus der DE 11 30 882 B ist ebenfalls ein Koaxialsteckverbinder bekannt.From the DE 11 30 882 B a coaxial connector is also known.

Ausgehend von diesem Stand der Technik lag der Erfindung die Aufgabe zugrunde, einen verbesserten Koaxialsteckverbinder anzugeben. Insbesondere sollte sich eine entsprechende, aus zwei derartigen Koaxialsteckverbindern ausgebildete Koaxialsteckverbindung durch eine geringe Intermodulation auszeichnen, die auch durch das Ausüben von lediglich geringen Axialkräften zur Verbindung der beiden Koaxialsteckverbinder sichergestellt werden kann.Based on this prior art, the object of the invention was to provide an improved coaxial connector. In particular, a corresponding coaxial connector formed from two such coaxial connectors should be distinguished by a low level of intermodulation, which can also be ensured by exerting only small axial forces for connecting the two coaxial connectors.

Diese Aufgabe wird durch den Gegenstand des Anspruchs 1 gelöst. Vorteilhafte Ausführungsformen des erfindungsgemäßen Koaxialsteckverbinders sind Gegenstand der abhängigen Ansprüche.This object is solved by the subject matter of claim 1. Advantageous embodiments of the coaxial connector according to the invention are the subject of the dependent claims.

Der Erfindung liegt der Gedanke zugrunde, die elektrische Kontaktierung zwischen zwei axial gegeneinander gedrückten Leitern, insbesondere Außenleitern von gattungsgemäßen Koaxialsteckverbindern, dadurch zu verbessern, dass deren axiale Kontaktflächen nicht mehr in einer (einzigen) Radialebene verlaufen, sondern in zumindest zwei und vorzugsweise einer Vielzahl von unterschiedlichen Ebenen.The invention is based on the idea of making electrical contact between to improve two axially pressed conductors, in particular outer conductors of generic coaxial connectors, in that their axial contact surfaces no longer run in a (single) radial plane, but in at least two and preferably a plurality of different planes.

Ein erfindungsgemäßer Koaxialsteckverbinder umfasst die Merkmale des Anspruchs 1. Die vorzugsweise mehreren Vorsprünge erzeugen definierte Kontaktstellen zwischen den beiden zu verbindenden Koaxialsteckverbindern, die einen geringen Störabstand auch dann aufweisen, wenn diese mit lediglich relativ geringer Axialkraft gegeneinander gedrückt werden. Dadurch kann die Montage der Koaxialsteckverbindung, d.h. das Verbinden der beiden Koaxialstecker erheblich vereinfacht werden.A coaxial connector according to the invention comprises the features of claim 1. The preferably several projections produce defined contact points between the two coaxial connectors to be connected, which also have a low signal-to-noise ratio when they are pressed against one another with only a relatively small axial force. This allows the assembly of the coaxial connector, i.e. the connection of the two coaxial connectors can be considerably simplified.

Eine entsprechende Koaxialsteckverbindung weist jeweils einen als Koaxialstecker sowie einen als Koaxialkuppler ausgebildeten Koaxialsteckverbinder auf, wobei zumindest einer, vorzugsweise beide der Koaxialsteckverbinder erfindungsgemäß ausgebildet sind.A corresponding coaxial connector each has a coaxial connector and a coaxial connector designed as a coaxial connector, at least one, preferably both, of the coaxial connectors being designed according to the invention.

Die axiale Kontaktfläche des Außenleiters ist mit spitz zulaufenden Vorsprüngen versehen. Diese können besonders bevorzugt eine dreieckige Grundform (d.h. gerade Flanken) aufweisen, so dass sich eine "sägezahnförmige" Kontur der Stirnseite des Außenleiters ergibt.The axial contact surface of the outer conductor is provided with tapered projections. These can particularly preferably have a triangular basic shape (i.e. straight flanks), so that there is a "sawtooth-shaped" contour of the end face of the outer conductor.

Die erfindungsgemäße Ausgestaltung eines Koaxialsteckverbinders mit einem oder mehreren, spitz zulaufenden Vorsprüngen weist bereits Vorteile bei einer Verbindung mit einem herkömmlichen Koaxialsteckverbinder auf, dessen axiale Kontaktfläche des Außenleiters in einer (einzigen) Radialebene verläuft. Besonders bevorzugt ist jedoch vorgesehen, dass beide Koaxialsteckverbinder erfindungsgemäß ausgebildet sind, wobei vorzugsweise vorgesehen sein kann, dass die Vorsprünge der beiden Koaxialsteckverbinder möglichst spielfrei ineinander greifen, um eine besonders gute elektrische Kontaktierung herzustellen. Hierzu weisen die einzelnen Vorsprünge der jeweiligen axialen Kontaktflächen der Außenleiter vorzugsweise gleiche Abmessungen auf und sind weiterhin bevorzugt in gleichmäßiger Teilung über die (ringförmige) axiale Kontaktfläche der jeweiligen Außenleiter verteilt angeordnet.The configuration according to the invention of a coaxial connector with one or more, tapering projections already has advantages in connection with a conventional coaxial connector, the axial contact surface of the outer conductor of which extends in a (single) radial plane. However, it is particularly preferably provided that both coaxial connectors are designed according to the invention, it being possible preferably for the projections of the two coaxial connectors to engage with one another with as little play as possible, in order to achieve a special one to make good electrical contact. For this purpose, the individual projections of the respective axial contact surfaces of the outer conductors preferably have the same dimensions and are furthermore preferably arranged in a uniform division over the (ring-shaped) axial contact surface of the respective outer conductors.

Um die Koaxialsteckverbindung in axialer Richtung sowie gegen Verdrehen zu sichern und zudem um eine ausreichende Axialkraft zu erzeugen, kann vorzugsweise vorgesehen sein, dass der Außenleiter des erfindungsgemäßen Koaxialsteckverbinder entweder ein Außengewinde oder eine Überwurfmutter aufweist, um mit einem entsprechenden zweiten Koaxialsteckverbinder (der dann das Gegenelement: Überwurfmutter oder Außengewinde aufweist) zur Ausbildung einer Koaxialsteckverbindung verschraubt zu werden. Ein erster der Koaxialsteckverbinder weist demnach einen Außenleiter mit einem Außengewinde und der entsprechende zweite Koaxialsteckverbinder eine Überwurfmutter auf, die auf das Außengewinde des ersten Koaxialsteckverbinders aufgeschraubt werden kann.In order to secure the coaxial connector in the axial direction and against rotation and also to generate a sufficient axial force, it can preferably be provided that the outer conductor of the coaxial connector according to the invention has either an external thread or a union nut in order to connect with a corresponding second coaxial connector (which then forms the counter element : Union nut or external thread) to be screwed to form a coaxial connector. A first of the coaxial connectors accordingly has an outer conductor with an external thread and the corresponding second coaxial connector has a union nut which can be screwed onto the external thread of the first coaxial connector.

Die erfindungsgemäße Ausgestaltung eines Koaxialsteckverbinders eignet sich insbesondere zur Verbesserung von Koaxialsteckverbindern, die im Übrigen, d.h. insbesondere hinsichtlich der Durchmesserabmessungen, gemäß der DIN 47 223 ausgebildet sind.The design of a coaxial connector according to the invention is particularly suitable for improving coaxial connectors which, moreover, i.e. in particular with regard to the diameter dimensions, are designed in accordance with DIN 47 223.

Furthermore, each of the coaxial plug connectors comprises an inner conductor 3, which is electrically conductively connected to a corresponding inner conductor 4 of the coaxial cable.

Auf der Innenseite des Außenleiters 1 des Koaxialkupplers 7 ist zudem ein radialer Absatz 9 ausgebildet, der als axialer Anschlag und gleichzeitig als axiale Kontaktfläche dieses Außenleiters 1 für das entsprechende steckseitige Ende des Außenleiters 1 des Koaxialsteckers 8 dient.The Indian Fig. 1 The first coaxial connector shown on the left is designed as a coaxial connector 7, the plug-side end of the inner conductor 3 being bush-shaped for receiving a corresponding pin-shaped end of the inner conductor 3 of the second coaxial connector 8, which is designed as a coaxial connector.

Die axialen Kontaktflächen der Außenleiter 1 der beiden Koaxialsteckverbinder gemäß der Fig. 1 sind erfindungsgemäß sägezahnförmig ausgebildet, d.h. sie bilden eine Vielzahl von identischen, in gleichmäßiger Teilung angeordneten, spitz zulaufenden Vorsprüngen 10 aus, die zwischen ebensolche Vorsprünge 10 der Kontaktfläche des jeweils anderen Außenleiters 1 eingreifen.The axial contact surfaces of the outer conductor 1 of the two coaxial connectors according to the Fig. 1 are sawtooth-shaped according to the invention, ie they form a plurality of identical, evenly spaced, tapered projections 10 which engage between such projections 10 of the contact surface of the other outer conductor 1.

Zur sicheren Verbindung der beiden Koaxialsteckverbinder ist der Koaxialstecker 8 mit einer Überwurfmutter 11 versehen, deren Innengewinde in ein korrespondierendes Außengewinde des Koaxialkupplers eingreift, wobei durch ein Verschrauben der beiden Gewindeteile die beiden Koaxialsteckverbinder axial gegeneinander gedrückt werden. Die drehbar auf dem Außenleiter 1 des Koaxialsteckers 8 gelagerte Überwurfmutter 11 stützt sich dabei an einem radialen Vorsprung 12 des Außenleiters 1 des Koaxialsteckers 8 ab.To securely connect the two coaxial connectors, the coaxial connector 8 is provided with a union nut 11, the internal thread of which engages in a corresponding external thread of the coaxial coupler, the two coaxial connectors being pressed axially against one another by screwing the two threaded parts.
