Definitions

  • the present invention relates to a device for connecting two microwave structures, of the coaxial type, but of different diameters.
  • coaxial lines and their connection accessories are standardized in dimensions. Thus, it is easy to assemble elements belonging to the same dimensional standard. However, it would sometimes be desirable to be able to produce microwave assemblies comprising coaxial elements of different diameters, some of them not necessarily being standardized.
  • a rigid coaxial line which must have a relatively large diameter in order to be able to contain a significant sample of said material.
  • Such a coaxial line can have a diameter of the order of 50 mm.
  • the object of the present invention is a device for connecting two microwave structures, coaxial and of different diameters, without disturbing the propagation of microwave waves.
  • the device for connecting two microwave structures, coaxial and of different diameters, each consisting of a central core and a peripheral envelope is remarkable in that it presents itself even a rigid coaxial structure comprising a central core in the form of a truncated cone, the circular bases of which have sections respectively identical to those of the central cores of said coaxial structures to be connected, as well as a peripheral envelope, the internal wall of which is a surface frustoconical, whose circular bases have sections respectively identical to the internal sections of the peripheral envelopes of said coaxial structures to be connected, in that the small bases of the truncated cones of said central core and of said peripheral envelope of said connector are two parallels of a first sphere centered on the apex of the frustoconical surface of said inner wall e t in that the large bases of the truncated cones of said central core and of said peripheral envelope of said fitting are two parallels of a second sphere concentric with the first.
  • connection device satisfies the above conditions, the propagation of the electromagnetic waves, from one coaxial structure to the other, takes place under optimal conditions.
  • the angle at the top of said frustoconical surface of the internal wall of the peripheral envelope of said fitting is at most equal to 15 °.
  • the transition between the two coaxial structures is then particularly gradual, so that the electromagnetic waves undergo little disturbance.
  • the truncated cone of the central core of said device is extended, on both sides, by cylindrical core portions of sections respectively identical to those of the cores of said coaxial structures to be connected, while said internal frustoconical surface of said peripheral envelope of said device is extended, on both sides, by cylindrical surfaces, the sections of which are respectively identical to the internal sections of the envelopes of said structures to be connected.
  • the central core of said connection device is secured to the casing by means of annular spacers.
  • these spacers it is advantageous for these spacers to be arranged between the cylindrical extensions of said core and of said peripheral envelope. At least one of these spacers can be housed, at its internal and / or external peripheries, in facing grooves, respectively formed in said core and / or in said peripheral envelope. It is then advantageous that such a spacer is arranged in the vicinity of one end of said connecting device, that said groove is delimited between one face of said peripheral envelope and a nozzle capable of being assembled to said body and that said core is made of at least two integral parts.
  • the connector 1, illustrated diagrammatically in FIG. 1, is intended to connect two coaxial structures for microwave, for example lines 2 and 3, of different diameters.
  • the coaxial line 2 of smaller diameter comprises a central cylindrical core 4, of diameter d1, and a peripheral cylindrical envelope 5, of internal diameter D1.
  • the coaxial line 3, of larger diameter comprises a central cylindrical core 6, of diameter d2, and a peripheral cylindrical envelope 7, of internal diameter D2.
  • connection 1 with respectively the coaxial lines 2 and 3 are assumed to be carried out in planes P1 and P2, using means not shown, which may have any known structure.
  • the connector 1 also has a coaxial structure, with a central core 8 and a peripheral envelope 9.
  • a central core 8 When said connector 1 joins the coaxial lines 2 and 3, these three elements are coaxial, at least in the vicinity of said connector 1.
  • Annular spacers 11 secure the core 8 of the envelope 9.
  • the central core 8 of the connector 1 has a frustoconical part 8a whose diameters of its end bases 12 and 13 are respectively equal to d1 and d2.
  • This frustoconical part 8a is extended, towards the coaxial line 2, by a cylindrical end part 8b, of diameter equal to d1, intended to be connected to the core 2 and, towards the coaxial line 3, by a part of cylindrical end 8c, of diameter equal to d2, intended to be connected to the core 6.
  • the peripheral envelope 9 of the connector 1 also has a frustoconical part 9a, extended on either side by parts 9b and 9c, respectively intended to be connected to the peripheral envelopes 5 and 7.
  • the internal wall 10 of the frustoconical part 9 a of the envelope 9 is a frustoconical surface and its angle at the apex A is at most equal to 15 °. Since the arrangement of the fitting is coaxial, the vertex B of the conical surface 10 is on the axis of said fitting 1.
  • the diameters of the bases 14 and 15 of the internal wall 10 are respectively equal to D2 and D1.
  • the small bases 13 and 15, respectively of the core part 8a and the internal wall 10 are parallels of a first sphere C1 centered at B, while the large bases 12 and 14, respectively of said core part 8a and of said internal wall 10, are parallels of a second sphere C2, also centered at B.
  • an electromagnetic wave passes with a minimum of disturbances from line 2 on line 3, and vice versa.
  • the spacers 11 securing the core 8 of the peripheral envelope 9 are located opposite the cylindrical parts 8b, 9b and 8c, 9c thereof and are engaged in grooves 11a, 11b formed in the surface of said parts.
  • connection device 1 In Figure 2, there is shown a practical embodiment of the connecting device according to the invention.
  • screw connection means 16 and 17 are provided, intended respectively to mechanically and electrically connect the connection device 1 to the line, or structure, 2 (not shown) and to the line, or structure 3. .
  • connection means 16 are formed by a screwed end piece further constituting the cylindrical part 9b of the casing 9, and intended to connect the core 8 to the core 4 and the envelope 9 to the envelope 5.
  • the connecting means 17 comprise a captive nut making it possible to press the corresponding ends of the cores 8 and 6 and the envelopes 7 and 9, one against the other.
  • the cylindrical part 9c is formed in part by a ring 20 secured by screwing the conical part 9a.
  • the spacer 11, disposed on the side of the smallest diameter is disposed in a groove in the part 8b, but is forced into the cylindrical part 9b.
  • the spacer 11, disposed on the side of the large diameter is disposed in such a groove in the part 8c and in a groove in the part 9c.
  • the part 8c consists of two parts which can be assembled by a screw 18, while the cylindrical part 9c comprises, in addition to the plate 20, a screwable end piece 21, so that the spacer 11 can be pressed between the ring 20 and end piece 21.
  • Guiding and centering means 19 are associated with the connecting means 17.
