(54) Bølgeleder, der har· massiv, metallisk væg og kan cpvikles, bøjes og vrides.(54) Waveguide having · solid, metallic wall and can be wound, bent and twisted.
Opfindelsen angår en bølgeleder, der har massiv, metallisk væg og kan opvik-les, bøjes og vrides, og hvis indre hulrum har rektangulært tværsnit med et forhold mellem sidelængderne på ca. 1:2, hvor de brede og de smalle siders yderkonturer i retning mod midten er trukket således cirkelbueformet indad, og vægtykkelserne i bølgeledertværsnittets omkredsretning i overensstemmelse hermed varierer således, at der ved bølgelederens krumning opstår i tværsnitsplanet liggende, I men uden for den indvendige kontur optrædende moddrejningsmomenter, der sammen • med i samme retning bøjende drejningsmomenter ophæver drejningsvirkningen af de andre momenter, der bevirker tværsnitsdeformeringen, så at der ved bølgelederens krumning opnås et optimalt formtro bølgeledertværsnit..The invention relates to a waveguide having a solid, metallic wall and which can be wound, bent and twisted, and whose inner cavity has a rectangular cross-section with a ratio of the side lengths of approx. 1: 2, where the outer and outer sides of the wide and narrow sides are drawn in a circular arc inwardly, and the wall thicknesses in the circumferential direction of the waveguide cross-section accordingly vary so that at the curvature of the waveguide, the transverse sectional plane is formed, but outside the inner contour. occurring counter-torques that, together with bending torques in the same direction, cancel the rotational action of the other moments causing the cross-sectional deformation, so that at the curvature of the waveguide, an optimum shape-true waveguide cross section is obtained.
Sådanne bølgeledere bruges især som forbindelsesledning mellem antennen og 1 sende-modtageapparater i retningsradioanlæg med radiofrekvenser over 3 GHz. Det 2 143375 er kendt at opbygge disse bølgelederstrækninger af delafsnit, nemlig lige bølgeledere, krumme stykker og snoningsstykker, hvorved disse dele bliver fremstillet i fabrikken og sammensat ved monteringspladsen. Ofte sker dog afvigelser af de virkelige lokale dimensioner eller eventuelt nødvendige ændringer, således at de forud fremstillede dele ikke mere passer sammen, og specielle længder af bølgele-derprofiler og formstykker skal efterfremstilles.In particular, such waveguides are used as a connection line between the antenna and 1 transmitter receiving devices in directional radio systems with radio frequencies above 3 GHz. It is known to build these waveguide sections of section sections, namely straight waveguides, curved pieces and twist pieces, whereby these parts are manufactured in the factory and assembled at the assembly site. However, often deviations from the actual local dimensions or any necessary changes occur, so that the pre-made parts no longer fit together and special lengths of waveguide profiles and moldings must be made.
I tysk offentliggørelsesskrift nr. 1.939.317 blev der allerede angivet en løsning for en bølgeleder, som på monteringspladsen kan tilpasses de forhåndenværende forhold og har i det mindste den samme overføringskvalitet som de hidtil brugte, stive bølgelederstrækninger. Denne bølgeleder har en sådan tværsnitsprofil, at der ved krumning og vridning om dens længdeakse opnås et optimalt formtro bølgeledertværsnit. Herved kan der fremstilles en bølgeleder af større længde, som i opviklet tilstand bringes til monteringspladsen og her ved monteringen bliver tilpasset den tilsigtede ledningsføring ved krumning eller bøjning eller ved vridning.German publication specification No. 1,939,317 already provided a solution for a waveguide that can be adapted to the existing conditions at the mounting site and has at least the same transmission quality as the previously used rigid waveguide sections. This waveguide has such a cross-sectional profile that, by curvature and twisting about its longitudinal axis, an optically true waveguide cross section is obtained. Hereby a larger length waveguide can be produced, which in the wound state is brought to the mounting place and here the mounting is adapted to the intended wiring by curvature or bending or by twisting.
Til grund for opfindelsen ligger den opgave yderligere at forbedre en sådan bølgeleder på en sådan måde, at de til opretholdelse af et optimalt formtro bølgeledertværsnit ved krumning og vridning nødvendige momenter holdes mindst mulige.The object of the invention is to further improve such a waveguide in such a way as to minimize the necessary moments for maintaining an optically true waveguide cross-section during curvature and twisting.
Denne opgave løses ved en bølgeleder af den i indledningen angivne art ifølge opfindelsen på en sådan måde, dels at de cirkelbueformede indtrækninger af de brede sider er således dimensioneret, at de brede siders vægtykkelse ved midten er ca. halvdelen af vægtykkelsen ved overgangen til de tilgrænsende smalle sider af det indre tværsnit, dels at yderkonturen af de brede sider er forlænget således ud over planerne for de tilgrænsende smalle siders indre konturer, at der dannes konsoller, hvis yderkonturer uden for de cirkelbueformede indtrækninger i de brede sider forløber parallelt med de indre konturer af de brede sider og ved de frie ender afrundet og kontinuert går over i de cirkelbueformede indtrækninger i de smalle sider, dels at længden af konsollerne samt disses bredde og dybden af indtrækningerne i de smalle sider er valgt således, at forholdet mellem længden og bredden af konsollerne målt i forhold til henholdsvis planerne for de smalle siders indre konturer og planerne for de brede siders indre konturer er ca. 2,5:1.This task is solved by a waveguide of the kind set forth in the preamble according to the invention in such a way that the circular arc-shaped indentations of the wide sides are dimensioned such that the wall thickness of the wide sides at the center is approx. half the wall thickness at the transition to the adjacent narrow sides of the inner cross section, and that the outer contour of the broad sides is extended so beyond the planes of the inner contours of the adjacent narrow sides that brackets are formed whose outer contours outside the circular indentations in the wide sides extend parallel to the inner contours of the wide sides and rounded at the free ends and continuously transition into the arcuate indentations in the narrow sides, partly that the length of the brackets and their width and the depth of the indentations in the narrow sides are selected thus , that the ratio of the length to the width of the brackets measured in relation to the plans for the inner contours of the narrow sides and the plans for the internal contours of the broad sides, respectively, is approx. 2.5: 1.
Ved udformningen svarende til det valgte vægtykkelsesforløb sikres et formtro bølgeledertværsnit ved bølgelederens krumning i H- og E-planet og ved vridning om dens længdeakse, og især ved krumningen i E-planet (x-x-planet) opnås et meget ringe modstandsmoment. På grund af denne bølgeleders lille tværsnitshøjde opstår mindre krumningsradier ved krumningen i E-planet ved ens mekaniske deformeringer i de yderste fibre end ved kendte bølgeledere. Ved krumningen i E-planet og ved en snoning med ligeledes ringe vridningsmoment kan der altså realiseres ledningsstrækninger udelukkende med små krumn ing sra die r. Den enkle geometriske yderkontur af bølgelederen er også fordelagtig, idet presseform, flange og fastgørelseselementer 3 143375 for bølgelederen bliver forenklet og flangebearbejdningen lettet. Desuden giver den gunstige formgivning, ved hjælp af hvilken der opnås et formtro bølgeledertvær-snit, gode pladssikre anlægsflader ved opviklingen af bølgelederen og muliggør anvendelse af simple bøjningsværktøjer, ved hvis hjælp bølgelederen ved monteringspladsen bøjes og vrides til opnåelse af den forudbestemte ledningsføring.In the design corresponding to the selected wall thickness course, a true waveguide cross section is ensured by the curvature of the waveguide in the H and E planes and by twisting about its longitudinal axis, and especially by the curvature in the E plane (x-x plane) a very low resistance moment is obtained. Due to the small cross-sectional height of this waveguide, smaller radii of curvature occur at the curvature of the E-plane by similar mechanical deformations in the outer fibers than by known waveguides. Thus, in the E-plane curvature and by a twist with equally low torque, wiring can be realized only with small curvature. The simple geometric outer contour of the waveguide is also advantageous, as the press shape, flange and fasteners for the waveguide are simplified. and flange machining facilitated. In addition, the favorable shaping by means of which a true waveguide cross sectional shape is obtained provides good site-safe abutment surfaces in the winding of the waveguide and enables the use of simple bending tools, by means of which the waveguide at the mounting site bends and turns to obtain the predetermined wiring.
En yderligere fordel er, at det ved den rektangulære bølgeleder ifølge opfindelsen er muligt at frembringe en direkte forbindelse mellem den bøjelige rektangulære bølgeleder og de sædvanlige bølgelederkomponenter med rektangulært tværsnit eller med de stive rektangulære bølgeledere, uden at der skal anvendes bølgelederovergange. Over for den stive bølgeleder består fordelen ved bortfald af krumme stykker, snoningsstykker og mellemstykker samt ved en væsentlig besparelse i planlægningstid og monteringsomkostninger.A further advantage is that in the rectangular waveguide of the invention it is possible to provide a direct connection between the flexible rectangular waveguide and the usual waveguide components of rectangular cross section or with the rigid rectangular waveguides without the need for waveguide transitions. Facing the rigid waveguide, the advantage of lapses consists of curved pieces, twist pieces and spacers as well as a significant saving in planning time and assembly costs.
Ved dimensioneringen ifølge opfindelsen opnås endvidere, at bølgelederens materialeforbrug ved en tilstrækkelig stabilitet bliver reduceret på fordelagtig måde, hvorved også energiforbruget til bøjningen og vridningen formindskes, og bølgelederens montering lettes.The design according to the invention furthermore achieves that the material consumption of the waveguide is reduced by a sufficient stability in an advantageous manner, thereby also reducing the energy consumption for the bending and twisting and facilitating the mounting of the waveguide.
Opfindelsen forklares nærmere i det følgende under henvisning til et på tegningen vist udførelseseksempel.The invention will be explained in more detail below with reference to an exemplary embodiment shown in the drawing.
Figuren viser i tværsnit en bølgeleder med rektangulært indvendigt tværsnit og en egnet profileret yderkontur, fortrinsvis bestående af blødt, elektrisk ledende materiale, især aluminium, og fremstillet ved en strengstøbeproces. Ved krumning af bølgelederen om bøjningsplanet x-x tilvejebringes parallelt med bøjningsplanet træk- og trykspændinger, som medfører kræfter q vinkelret på bøjningsplanet. Disse kræfter afhænger af krumningsradius, tværsnitsfladeindholdet og tværsnitsformen og fremkalder drejningsmomenter M, som deformerer bølge lederkonturen. Som det kan påvises ved udregning, kan tværsnitsdeformeringen styres gennem hensigtsmæssig dimensionering af tværsnitsfladen. Ved given rektangulær eller vilkårlig indvendig kontur af bølgelederen er en minimal tværsnitsdeformering opnåelig, når yderkonturen vælges således, at der ved bølgelederens krumning opstår drejningsmomenter M, der sammen med drejningsmomentet Mq ophæver momentet M’s drejningsv irkn ing.The figure shows in cross-section a waveguide with rectangular internal cross-section and a suitable profiled outer contour, preferably consisting of soft, electrically conductive material, especially aluminum, and produced by a string casting process. By curvature of the waveguide about the bending plane x-x, tensile and compressive stresses are produced parallel to the bending plane which cause forces q perpendicular to the bending plane. These forces depend on the radius of curvature, the cross-sectional surface content and the cross-sectional shape and induce torques M which deform the wave conductor contour. As can be demonstrated by calculation, the cross-sectional deformation can be controlled through appropriate sizing of the cross-sectional surface. For a given rectangular or arbitrary internal contour of the waveguide, a minimum cross-sectional deformation is obtained when the outer contour is selected such that at the curvature of the waveguide, torque M arises, which together with torque Mq cancels torque M's torque.
Ved bølgelederen ifølge opfindelsen er yderkonturen af de brede sider 1 og de smalle sider 2 trukket ind hen mod midten, fortrinsvis cirkelbueformet, således at der ved disse indadbøjninger 4 og 5 opstår forskellige vægtykkelser i periferiretningen af bølgelederens tværsnit. De brede sider 1 af bølgelederen er forlænget ud over de smalle sider under dannelse af de såkaldte konsoller 3. Disse forlængelser er således udformet og dimensioneret, at der med hensyn til de enkelte smalle sider og de enkelte kvadranter i bølgeledertværsnittet opstår en i det mindste tilnærmet symmetrisk T-profil og med hensyn til de enkelte brede si*-In the waveguide according to the invention, the outer contour of the wide sides 1 and the narrow sides 2 is drawn towards the center, preferably circular arcuate, so that at these inward bends 4 and 5 different wall thicknesses are formed in the circumferential direction of the cross-section of the waveguide. The wide sides 1 of the waveguide are extended beyond the narrow sides to form the so-called brackets 3. These extensions are designed and dimensioned so that, with respect to the individual narrow sides and the individual quadrants in the waveguide cross section, at least approximately symmetrical T-profile and with respect to the individual wide screens * -
