Definitions

  • the present invention relates to the manufacture of elbows for microwave waveguides rectangular.
  • Elbows for microwave waveguides rectangular serve to ensure changes of direction at 90 °, approximately, or less, both in plane E containing the electric field only in the H plane containing the magnetic field.
  • elbows exist at this day, of which a first type consisting of a tube of curved rectangular section, at the ends of which are attached by welding the connection flanges.
  • a monolithic version of this type of elbow is produced by molding, using the so-called wax process lost. In both cases, the cost of production is relatively high.
  • Another type of elbow is obtained from two complementary rooms in each of which a half-tunnel the entire length of the elbow is hollowed out from a flat connection face, the two half-tunnels then being placed opposite and the two parts joined together by means of a plurality of screws.
  • bends including the tunnel, side exterior of change of direction, presents a pan transition with a succession of steps or bleachers.
  • the invention comes from research carried out relative to bends for waveguides rectangular microwave in order to reach the following objectives: simplicity of manufacture inducing an attractive cost price; good reproducibility to allow productions of mass within tight tolerances; good aptitude for miniaturization by elimination as best as possible space constraints other than inherent to functional dimensions.
  • the invention consists of a method of fabrication of a waveguide bend rectangular microwave, which elbow has a internal tunnel formed by two straight sections joining by defining a dihedral inside side of the change of direction, and opposite the summit of said dihedral, outside side of the change of direction, a stepped transition section, characterized in that it consists of making by machining in a block, from two sides of said block forming the elbow connection ends, two bores rectangular meeting so as to define, in their meeting place, said dihedral on the inner side of the change of direction, and said transition pan to steps on the outside of the change of direction.
  • said bores are advantageously achievable by the technique of milling that offers a degree of precision totally satisfactory for the intended applications (frequencies from 10 to 20 GHz) and which would remain sufficient far beyond of these frequencies (at least up to 60 GHz).
  • FIGs. 1 and 2 illustrate the invention by representation of an elbow C for rectangular microwave waveguide, in the case of an orthogonal elbow with change of direction in plane E (containing the field electric) corresponding to the height b of the guide, and made of a conventional material such as alloy aluminum.
  • Elbow C consists of a parallelepiped block 1 having two orthogonal connecting faces, respectively F1 and F2, between which was machined the internal guide tunnel T.
  • this consists of two orthogonal bores A1, A2 of section rectangular (a, b), formed respectively from faces F1 and F2, and which join in defining, inner side of the change of direction, Fig. 2, a right dihedron with vertex S, and outer side of the change of direction, a transitional cutaway P substantially at 45 ° opposite the vertex S, and consisting of a succession of G steps.
  • the steps G are straight steps, which therefore each have a wall parallel to the walls of width a of the bore A1, and a wall parallel to the walls of width a of bore A2.
  • the elbow C is advantageously produced by milling, for example according to a machining process in which is carried out first bore A1 with a bottom stepped on one of its sides to constitute the whole steps G, after which bore A2 is made.
  • the machining of hole A1 can be stopped at level of the first tier, i.e. the highest tier high in it, or at a level intermediate, and make the remaining steps during the machining of bore A2.
  • Fig. 3 represents an elbow of the same design that the elbow C previously described, which presents all the characteristics and, therefore, has the same references, with the sign premium.
  • the elbow C ' is also achievable by milling, as explained in the previous paragraph, and it differs in fact from the elbow C only in that its G 'steps are considerably increased in number by compared to that of the steps G, their dimensions are finding of course decreased by as much as the shows the succession of parallel fine mixed lines schematically representing the machining increments in one dimension; so that the pan of transition P 'becomes a flat wall, or more exactly is comparable in practice to a wall plane in which the steps G 'no longer have as effect than giving it a certain roughness.
  • Fig. 4 illustrates another advantage of the invention, which makes it possible to combine several elbows in the form of several guide tunnels T1, T2 machined side by side in a single block 10.
