Description

Die Erfindung bezieht sich auf einen Hohlleitertwist zur Verbindung von elektromagnetischen Hohlleitern, bestehend aus einem Torsionselement mit mindestens drei lückenlos nebeneinander liegenden, um die Achse desselben drehbaren Einzelteilen, bei welchem jedes der Einzelteile ein zentrales Durchgangsloch mit einem dem lichten Querschnitt der Hohlleiter entsprechenden Querschnitt hat und bei welchem die Durchgangslöcher der Einzelteile im nicht gedrehten Zustand des Torsionselements miteinander fluchten (DE-C-3 733 397).The invention relates to a waveguide twist for connecting electromagnetic waveguides, consisting of a torsion element with at least three gaps lying side by side without gaps around the axis of the same rotatable individual parts, in which each of the individual parts is a central Through hole with a corresponding cross section of the waveguide Has cross-section and in which the through holes of the individual parts are not aligned rotated state of the torsion element with each other (DE-C-3 733 397).

Ein derartiger Hohlleitertwist kann zum Verbinden von rechteckigen oder elliptischen Hohlleitern eingesetzt werden. Der Einfachheit halber wird im folgenden der rechteckige Querschnitt berücksichtigt, stellvertretend auch für den elliptischen Querschnitt. Ein solcher Hohlleitertwist wird beispielsweise benötigt, wenn ein Hohlleiter mit einem anderen Hohlleiter bzw. mit einem Gerät mit einem Hohlleiteranschluß verbunden werden soll und wenn die Achsen der jeweiligen Anschlußstellen in gegeneinander verdrehten Ebenen liegen. Ein möglicher Einsatzbereich ist beispielsweise bei Antennen mit parabolischem Reflektor und einer durch einen rechteckigen Hohlleiter gebildeten Speiseleitung gegeben. An die Speiseleitung wird ein weiterführender Hohlleiter angeschlossen, welcher die Verbindung zu einer Sende- und Empfangsanlage herstellt. Zwischen die Speiseleitung und den weiterführenden Hohlleiter kann ein Gerät eingeschaltet sein, das beispielsweise Mischer oder andere elektronische Bauteile enthält. Die Polarisationsebene, in welcher die zu übertragenden elektromagnetischen Wellen schwingen, liegt durch den rechteckigen Hohlleiter der Speiseleitung fest. Sie wird für die Antenne durch entsprechende Drehung bzw. Anordnung der Speiseleitung im Reflektor eingestellt. Das Anschlußende der Speiseleitung wird dabei mit eingestellt, so daß deren rechteckige Öffnung unterschiedliche Positionen einnehmen kann. Das kann dann zu Schwierigkeiten führen, wenn die Position des weiterführenden Hohlleiters und insbesondere die Position eines zwischenzuschaltenden Geräts festliegen, wodurch auch die Position der Anschlußöffnungen dieser Bauteile festliegt. Es müssen dann für den jeweiligen Anwendungsfall anzufertigende Übergangsbauteile eingesetzt werden, die eine möglichst verlustarme Führung der Wellen zwischen der Speiseleitung und dem an dieselbe anzuschließenden Bauteil ermöglichen.Such a waveguide twist can be used to connect rectangular or elliptical Waveguides are used. For the sake of simplicity, the following is the rectangular cross-section taken into account, representative of the elliptical Cross-section. Such a waveguide twist is required, for example, if a Waveguide with another waveguide or with a device with one Waveguide connection should be connected and if the axes of the respective Connection points are in mutually rotated planes. A possible one Areas of application are, for example, antennas with a parabolic reflector and one given by a rectangular waveguide feed line. To the A further waveguide is connected to the feeder line Establishes a connection to a transmitting and receiving system. Between the A device can be switched on the feed line and the outgoing waveguide, which contains, for example, mixers or other electronic components. The Polarization plane in which the electromagnetic waves to be transmitted swing, is fixed by the rectangular waveguide of the feed line. It will be for the antenna by appropriate rotation or arrangement of the feed line in Reflector set. The connection end of the feed line is also set, so that their rectangular opening can assume different positions. The can cause difficulties if the position of the continuing Waveguide and in particular the position of an intermediate device are fixed, whereby the position of the connection openings of these components is also fixed. It must then be made for the respective application Transitional components are used, which guide the loss with as little loss as possible Waves between the feed line and the component to be connected to it enable.

Der Hohlleitertwist nach der eingangs erwähnten DE-C-3 733 397 besteht beispielsweise aus drei Hohlleiterabschnitten, die um ihre Längsachse gegeneinander verdrehbar miteinander verbunden sind. Dadurch ist der Hohlleitertwist auf unterschiedliche Winkel zwischen den Achsen der lichten Querschnitte an seinen beiden Enden einstellbar. Am mittleren Hohlleiterabschnitt ist außen ein in Längsrichtung des Hohlleitertwists verlaufender Hebel drehbar angebracht. An den beiden Enden des Hebels stehen Zapfen ab, die in Führungsnuten eingreifen, welche außen an den beiden anderen Hohlleiterabschnitten, in Längsrichtung des Hohlleitertwists verlaufend, angebracht sind. Der Aufbau dieses bekannten Hohlleitertwists ist aufwendig. Er wird mit zunehmender Anzahl von Hohlleiterabschnitten komplizierter. Die Winkel, um weiche die Hohlleiterabschnitte gegeneinander verdrehbar sind, ist dadurch begrenzt, daß die Zapfen des Hebels noch in die Führungsnuten der Hohlleiterabschnitte eingreifen.The waveguide twist according to the aforementioned DE-C-3 733 397 exists For example, from three waveguide sections that are mutually opposite about their longitudinal axis are rotatably connected. As a result, the waveguide twist is open different angles between the axes of the clear cross sections at its adjustable at both ends. At the middle waveguide section there is an in Lever extending lever longitudinally rotatably attached. To the Both ends of the lever protrude from pins which engage in guide grooves, which outside on the other two waveguide sections, in the longitudinal direction of the Waveguide twists running, are attached. The structure of this well-known Waveguide twists is complex. It increases with the number of Waveguide sections more complicated. The angles at which the waveguide sections deviate are rotatable against each other, is limited in that the pin of the lever still engage in the guide grooves of the waveguide sections.

Der Erfindung liegt die Aufgabe zugrunde, den eingangs geschilderten Hohlleitertwist ohne Begrenzung des Drehwinkels einfacher zu gestalten.The invention has for its object the waveguide twist described above easier to design without limiting the angle of rotation.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst,

  • daß in jeweils einer Stirnseite der Einzelteile eine Vertiefung angebracht ist, deren Erstreckung in Umfangsrichtung einem vorgegebenen Drehwinkel entspricht,
  • daß von der anderen Stirnseite der Einzelteile in axialer Richtung verlaufende Stifte abstehen und
  • daß in Montageposition des Torsionselements ein von einem Einzelteil abstehender Stift in die an der Stirnseite des benachbarten Einzelteils befindliche Vertiefung eingreift.
According to the invention, this object is achieved by
  • that a recess is made in each end face of the individual parts, the extent of which corresponds to a predetermined angle of rotation in the circumferential direction,
  • that protrude from the other end face of the individual parts in the axial direction and
  • that in the assembly position of the torsion element, a pin protruding from an individual part engages in the recess located on the end face of the adjacent individual part.

Dieser Hohlleitertwist ist einfach aufgebaut und einfach zu betätigen, ohne daß von außen sichtbare Teile verwendet werden. Sein Drehwinkel wird nur von der Erstreckung der in den Einzelteilen angebrachten Vertiefungen in Umfangsrichtung begrenzt. Er besteht aus einer geeigneten Anzahl von Einzelteilen, von denen das eine bei einer Drehung das benachbarte durch den in die entsprechende Vertiefung eingreifenden Stift mitnimmt. Bei einer Drehung eines am Ende des Torsionselements befindlichen Einzelteils um den vorgegebenen Drehwinkel werden also alle anderen Einzelteile automatisch mitgenommen und um den jeweils richtigen Winkel gedreht. Die Winkel, um welche die Einzelteile zu drehen sind, werden bei gleichbleibendem Drehwinkel des Hohlleitertwists um so kleiner, je mehr Einzelteile eingesetzt werden. Die durch das Torsionselement hervorgerufenen elektrischen Verluste werden mit steigender Anzahl von Einzelteilen geringer. Der Reflexionsfaktor desselben wird dann günstiger. Das Torsionselement ist nicht nur beim Erstaufbau einer Hohlleiteranordnung von Vorteil, sondern auch dann, wenn beispielsweise an einer bereits installierten Antennenanordnung eine andere Polarisationsebene eingestellt werden soll.This waveguide twist is simple in construction and easy to operate without having to externally visible parts are used. Its angle of rotation is only determined by the Extension of the recesses made in the individual parts in the circumferential direction limited. It consists of a suitable number of individual parts, of which the one with a rotation the neighboring through the into the corresponding recess engaging pin. When rotating one at the end of the torsion element individual parts located around the specified angle of rotation are all others Individual parts are automatically taken along and rotated through the correct angle. The angles around which the individual parts are to be rotated remain the same The more individual parts are used, the smaller the angle of rotation of the waveguide twist. The electrical losses caused by the torsion element are included increasing number of individual parts less. The reflection factor of the same will then cheaper. The torsion element is not only one when it is first assembled Waveguide arrangement is advantageous, but also when, for example, on a already installed antenna arrangement set a different polarization level shall be.

Ein Torsionselement für einen Hohlleitertwist nach der Erfindung hat mindestens drei lückenlos nebeneinander liegende Einzelteile, die um die Achse des Torsionselements drehbar sind. Dabei können die beiden Endteile auch von den beiden miteinander zu verbindenden Hohlleitern gebildet sein. In diesem Extremfall ist dann zwischen den beiden Hohlleitern nur ein zusätzliches Einzelteil angeordnet. Die Einzelteile haben alle ein rechteckiges (elliptisches), zentrales Durchgangsloch, dessen lichte Weite und Abmessungen jeweils gleich sind. Die Einzelteile des Torsionselements sind in bevorzugter Ausführungsform kreisrunde Scheiben. Sie können dann besonders einfach in einem zylindrischen Gehäuse zusammengehalten und geführt werden, dessen Innendurchmesser dem Außendurchmesser der Scheiben entspricht. Es ist aber auch jeder andere sinnvolle Aufbau des Torsionselements denkbar, mit dem alle Einzelteile als Einheit zusammengehalten werden können und das die relative Drehbarkeit der Einzelteile sicherstellt.A torsion element for a waveguide twist according to the invention has at least three individual parts lying next to each other without gaps, around the axis of the Torsion element are rotatable. The two end parts can also be from the two waveguides to be connected to one another. In this extreme case then only one additional individual part is arranged between the two waveguides. The Individual parts all have a rectangular (elliptical), central through hole, whose clear width and dimensions are the same. The individual parts of the In a preferred embodiment, torsion elements are circular disks. she can then be held together particularly easily in a cylindrical housing and are guided, the inside diameter of the outside diameter of the Discs corresponds. But it is also every other meaningful structure of the Torsion element conceivable with which all individual parts are held together as a unit can and that ensures the relative rotatability of the individual parts.

Gemäß dem in Fig. 1 dargestellten Ausführungsbeispiel besteht ein Torsionselement 1 für einen Hohlleitertwist aus fünf Einzelteilen. Das sind vier kreisrunde Scheiben 2, die in einem zylindrischen, topfförmigen Gehäuse 3 als fünftem Einzelteil um eine gemeinsame Achse drehbar gelagert sind. Der Innendurchmesser des Gehäuses 3 entspricht dem Außendurchmesser der Scheiben 2. Das Gehäuse 3 kann in Montageposition in Umfangsrichtung drehbar an einer Halteplatte 4 angebracht sein. Es greift dabei in Langlöcher 5 und 6 der Halteplatte 4 ein (Fig. 4). Auf der gegenüber liegenden Seite ist an der Halteplatte 4 eine Speiseleitung 7 für eine Antenne befestigt, bei der es sich beispielsweise um einen Hohlleiter mit rechteckigem Querschnitt handelt. Alle Scheiben 2 und der Boden 8 des Gehäuses 3 haben ein zentrales, rechteckiges Durchgangsloch 9. In unverdrehtem Zustand des Torsionselements 1 fluchten die Durchgangslöcher 9 aller Einzelteile 2 und 8 desselben untereinander und mit der Speiseleitung 7, so wie es aus Fig. 1 hervorgeht.According to the embodiment shown in Fig. 1 there is a torsion element 1 for a waveguide twist made of five individual parts. That’s four circular disks 2, which in a cylindrical, pot-shaped housing 3 as a fifth item by one common axis are rotatably mounted. The inside diameter of the housing 3 corresponds to the outer diameter of the discs 2. The housing 3 can in Mounting position can be rotatably attached to a holding plate 4 in the circumferential direction. It engages in slots 5 and 6 of the holding plate 4 (Fig. 4). On the opposite lying side is on the holding plate 4, a feed line 7 for an antenna attached, for example, a waveguide with a rectangular Cross section. All discs 2 and the bottom 8 of the housing 3 have one central, rectangular through hole 9. In the untwisted state of the Torsion element 1 align the through holes 9 of all individual parts 2 and 8 the same with each other and with the feed line 7, as shown in Fig. 1.

Jede der Scheiben 2 hat an einer Stirnseite eine Vertiefung, die in bevorzugter Ausführungsform als sich in Umfangsrichtung erstreckendes Langloch 10 ausgebildet ist. Die Vertiefung könnte auch kreisrund oder mit anderem Querschnitt ausgeführt sein. Wichtig ist nur die Länge ihrer Erstreckung in Umfangsrichtung. Stellvertretend für alle möglichen Ausführungsformen wird im folgenden das Langloch 10 berücksichtigt. An der jeweils anderen Stirnseite der Scheiben 2 steht in axialer Richtung ein Stift 11 ab. In Montageposition greift jeweils ein Stift 11 der einen Scheibe 2 in ein Langloch 10 der benachbarten Scheibe 2 ein. Die Länge der Langlöcher 10 begrenzt den Winkel, um welchen eine Scheibe 2 relativ zu einer benachbarten Scheibe 2 drehbar ist. Im dargestellten Ausführungsbeispiel hat auch der Boden 8 des Gehäuses 3 einen Stift 11, der in das Langloch 10 der an demselben anliegenden Scheibe 2 eingreift. Die Halteplatte 4 ist ebenfalls mit einem Langloch 10 zur Aufnahme des Stiftes 11 der anliegenden Scheibe 2 ausgerüstet.Each of the disks 2 has a recess on one end face, which is preferred Embodiment designed as an elongated hole 10 extending in the circumferential direction is. The depression could also be circular or with a different cross section his. Only the length of their extent in the circumferential direction is important. Representative for all possible embodiments, the elongated hole 10 considered. On the other end of the discs 2 is in the axial Towards a pin 11. In the assembly position, a pin 11 engages one Disc 2 in an elongated hole 10 of the adjacent disc 2. The length of the Elongated holes 10 limit the angle by which a disc 2 relative to one adjacent disc 2 is rotatable. In the illustrated embodiment also the bottom 8 of the housing 3 a pin 11, which in the slot 10 of the engages the same adjacent disc 2. The holding plate 4 is also with a Elongated hole 10 equipped for receiving the pin 11 of the adjacent disc 2.

Bei einem Torsionselement 1 mit den geschilderten fünf Einzelteilen - das sind der Boden 8 des Gehäuses 3 und vier Scheiben 2 - haben die Langlöcher 10 beispielsweise jeweils eine einem Winkel von 18° entsprechende Länge. Das Durchgangsloch 9 im Boden des Gehäuses 3 ist dann gegenüber der Speiseleitung 7 um einen Drehwinkel von 90° drehbar. Wenn ein anderer Drehwinkel erreicht werden soll, muß entweder bei gleichbleibender Länge der Langlöcher 10 die Anzahl der Scheiben 2 oder bei gleichbleibender Anzahl von Scheiben 2 die Länge der Langlöcher 10 verändert werden.In the case of a torsion element 1 with the five individual parts described - these are the Bottom 8 of the housing 3 and four disks 2 - have the elongated holes 10 for example, a length corresponding to an angle of 18 °. The Through hole 9 in the bottom of the housing 3 is then opposite the feed line 7 rotatable by a rotation angle of 90 °. If a different angle of rotation can be achieved if the length of the elongated holes 10 must be the same either the number of Slices 2 or, if the number of slices 2 remains the same, the length of the Elongated holes 10 are changed.

Die Langlöcher 10 können in allen Scheiben 2 jeweils die gleiche Länge in Umfangsrichtung haben, so wie es mit dem Winkel von 18° erläutert ist. Sie können aber auch unterschiedlich lang sein, so daß die einzelnen Scheiben 2 unterschiedlich weit gedreht werden. Bei dem geschilderten Ausführungsbeispiel mit fünf Scheiben 2 und einem Drehwinkel von 90° könnten die der jeweiligen Länge in Umfangsrichtung entsprechenden Winkel der nebeneinander liegenden Scheiben 2 auch wie folgt abgestuft sein: 12°-20°-24°-20°-12°. Ein solcher Aufbau eines Torsionselements 1 kann einen noch günstigeren Reflexionsfaktor ergeben.The elongated holes 10 can each have the same length in all disks 2 Have circumferential direction, as explained with the angle of 18 °. You can but also be of different lengths, so that the individual disks 2 are different be rotated far. In the described embodiment with five disks 2 and a rotation angle of 90 ° could that of the respective length in the circumferential direction corresponding angle of the adjacent discs 2 also as follows graded: 12 ° -20 ° -24 ° -20 ° -12 °. Such a structure of a torsion element 1 can result in an even more favorable reflection factor.

In Fig. 5 ist schematisch die Spitze eines Mastes 12 angedeutet, auf welchem ein parabolischer Reflektor 13 einer Antenne montiert ist. Im Reflektor 13 ist die als rechteckiger Hohlleiter ausgeführte Speiseleitung 7 befestigt, an deren freiem Ende ein der Ausleuchtung der Antenne dienender Erreger 14 angebracht ist. Auf der der Speiseleitung 7 abgewandten Seite des Reflektors 13 ist ein Gerät 15 auf dem Mast 12 montiert, an welches ein Hohlleiter 16 angeschlossen ist, der mit einer nicht mit dargestellten Sende- und Empfangseinrichtung verbunden ist. Zwischen dem Gerät 15 und der Speiseleitung 7 ist ein Torsionselement 1 angebracht.
