Description

Koaxialsteckverbinder  coaxial
Die Erfindung betrifft einen Koaxialsteckverbinder und insbesondere einen gemäß der DIN 47 223 ausgebildeten Koaxialsteckverbinder sowie eine aus zwei solchen Koaxialsteckverbindern ausgebildete Koaxialsteckverbindung.  The invention relates to a coaxial connector and in particular a trained according to DIN 47 223 coaxial connector and a coaxial connector formed from two such Koaxialsteckverbindern.
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. In DIN 47 223 a coaxial connector is normalized, the inner conductor has an outer diameter of about 7 mm and the outer conductor has an inner diameter of about 16 mm. Coaxial connectors according to DIN 47 223 are therefore also referred to as 7/16 coaxial connector. Due to the specific diameter ratio, a wave resistance of approximately 50 Ω is achieved with air as the dielectric between the plug-in 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 Koa- xialsteckers 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 trained in accordance with DIN 47 223 coaxial connector in the form of a coaxial connector has plug side a pin-shaped end of the inner conductor, which is inserted into a corresponding socket-shaped end of the inner conductor of a coaxial connector designed as a coaxial connector. The outer conductor of the coaxial connector contacts the outer conductor of the coaxial coupler in both the axial and radial direction, by the tubular end of the outer conductor of the coaxial xialsteckers is pressed against an annular shoulder, which is formed from the inside of the outer conductor of the coaxial coupler. The axial force required for this purpose is applied by a union nut, which is rotatably mounted on one of the connectors and is screwed onto a provided on the corresponding other connector external thread. At the same time, this screwed connection serves to secure the coaxial connector against unintentional release. Such a coaxial connector is known for example from DE 43 00 243 C1.
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 coaxial connector as low as possible, some extremely low interference margins are prescribed for these, which can only be achieved by pressing the two coaxial connectors of a coaxial connector against each other under very high axial forces. For example, in the cabling of mobile 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 Koaxialsteckverbindung can therefore be ensured only by the use of a sufficiently large-sized torque wrench, which is associated with a considerable 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 US 6,837,754 B1 also adapter elements with which a plurality of cables bundled are connected to a terminal of a transformer, known. Each of these connections comprises an annular coupling body against which an annular coupling body of the associated adapter element is clamped for the production of the connection. The contact surfaces of the coupling body are provided with projections and depressions, engage in the corresponding projections or depressions of the counter element. As a result, the contact surface between the two contact bodies should be made as large as possible.
Ausgehend von diesem Stand der Technik lag der Erfindung die Aufgabe zugrunde, einen verbesserten Koaxialsteckverbinder sowie eine entsprechende, aus zwei der- artigen Koaxialsteckverbindern ausgebildete Koaxialsteckverbindung anzugeben. Insbesondere sollte sich die erfindungsgemäße Koaxialsteckverbindung durch eine geringe Intermodulation auszeichnen, die auch durch das Ausüben von lediglich ge- Starting from this prior art, the invention was based on the object, an improved coaxial connector and a corresponding, from two der- specify coaxial connector designed coaxial connector specify. In particular, the coaxial connector according to the invention should be characterized by a low intermodulation, which can also be achieved by exercising only

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 to improve the electrical contact between two axially against each other pressed conductors, in particular outer conductors of generic Koaxialsteckverbindern, characterized in that their axial contact surfaces no longer in a (single) radial plane, but in at least two and preferably a plurality of different levels.

Diese 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, which generically has an outer conductor, an inner conductor and an insulator connecting the outer and inner conductors, the outer conductor having an axial contact surface for electrically conductive contact with an outer conductor of a second coaxial connector, characterized in that the axial contact surface (At least) of the outer conductor is provided with one or more projections. These preferably a plurality of projections produce defined contact points between the two coaxial connectors to be connected, which have a low signal to noise ratio even when they are pressed against each other with only a relatively small axial force. This allows the installation of the coaxial connector, ie the Connecting the two coaxial connectors are greatly simplified.

A corresponding coaxial connector according to the invention has in each case one coaxial connector and a coaxial connector designed as a Koaxialsteckver- i binder, wherein at least one, preferably both of the coaxial connector according to the invention are formed.
In einer bevorzugten Ausführungsform des erfindungsgemäßen Koaxialsteckverbinders ist die axiale Kontaktfläche des Außenleiters mit spitz zulaufenden Vorsprün- ) gen versehen. Diese können besonders bevorzugt eine dreieckige Grundform (d.h. gerade Flanken) aufweisen, so dass sich eine„sägezahnförmige" Kontur der Stirnseite des Außenleiters ergibt. In a preferred embodiment of the coaxial connector according to the invention, the axial contact surface of the outer conductor is provided with tapered Vorsprün- gene. These may particularly preferably have a triangular basic shape (i.e., straight flanks), so that a "sawtooth" contour of the front side of the outer conductor results.
In einer alternativen Ausführungsform kann die axiale Kontaktfläche des Außenlei- i ters des erfindungsgemäßen Koaxialsteckverbinders beispielsweise auch wellenförmig ausgebildete Vorsprünge aufweisen. In an alternative embodiment, the axial contact surface of the outer conductor of the coaxial connector according to the invention may, for example, also have undulating projections.

Besonders bevorzugt ist jedoch vorgesehen, dass beide Koaxialsteckverbinder erfindungsgemäß ausgebildet sind, wobei vorzugsweise vorgesehen sein kann, dass die Vorsprünge der beiden Koaxialsteckverbinder möglichstI already have advantages in connection with a conventional coaxial connector, whose axial contact surface of the outer conductor extends in a (single) radial plane. However, it is particularly preferred that both coaxial connectors are designed according to the invention, wherein it may preferably be provided that the projections of the two coaxial connectors are as possible

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 distributed in uniform pitch over the (annular) axial contact surface of the respective outer conductor.
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, may preferably be provided that the outer conductor of the coaxial connector according to the invention either an external thread or a union nut to a corresponding second coaxial connector (then the counter element : Union nut or external thread has) to be screwed to form a Koaxialsteckverbindung. A first of the coaxial connector thus has an outer conductor with an external thread and the corresponding second coaxial connector on a union nut, which can be screwed onto the external thread of the first coaxial connector.
