Definitions

  • the present invention relates to an internal conductor coaxial support for high frequency and microwave coaxial lines and connectors.
  • the coaxial lines and the coaxial connectors are used for the transmission under shielding of electromagnetic waves.
  • the line has a homogeneous construction longitudinally and thus a defined characteristic impedance and that the inner conductors arranged concentrically are fixed in longitudinal and transverse directions with respect to the outer conductors without this attachment is not adversely affected by circulating electromagnetic waves.
  • the connectors such supports must also make it possible to absorb, without mechanical deformation, the connection and disconnection forces acting in the longitudinal direction.
  • the supports in the form of discs currently used consist most often of a cylindrical body in solid or cellular dielectric which is placed between elements of internal conductor and external conductor produced in a special way.
  • This arrangement has the disadvantage of reducing the maximum transmissible frequency because, due to the shortening of the wavelength in the dielectric, it occurs already before the limit frequency of the connected coaxial line is obtained, that is to say -already say for lower frequencies, undesirable oscillation modes which impair transmission.
  • the present invention proposes to provide a construction which prevents this frequency limitation and which, thanks to its new design, further improves the longitudinal rigidity and the transverse rigidity of the support compared to the usual embodiments currently.
  • the subject of the present invention is a mechanically rigid support for an inner conductor for high frequency and microwave coaxial lines and connectors, characterized in that it comprises an outer conductor element with symmetry of revolution provided with at least four slots and an inner conductor of reduced section to keep the characteristic impedance constant over the length of the support, the inner conductor being automatically centered and immobilized longitudinally by at least four elastic dielectric plates preformed convexly with respect to the median axis and introduced into the slots of the outer conductor element.
  • the external conductor element has a reduced internal diameter relative to the coaxial connection line, ensuring a transmission limit frequency at least as high as the coaxial connection line insulated with air.
  • the support according to the invention comprises a segmented arrangement of dielectric supports (d) in the form of sheets or plates which, in the form of quarter arcs, automatically center the inner conductor (i ) in relation to the external conductor.
  • the inner conductor of reduced section along the length I 1 can be of circular section of diameter di (fig. 1) or of polygonal section, in particular square (fig. 2A), ensuring immobilization in rotation relative to to the outside conductor.
  • An externally pressed locking sleeve (m) reinforces this centering and ensures blocking.
  • Z designates the characteristic impedance in Ohm, e. the relative dielectric constant resulting from the introduction of the dielectric plates, D 1 the internal diameter of the split element of external conductor n, d 1 the diameter of the internal conductor.
  • the narrowing of the inner conductor i and the reduction of the inner diameter D 1 of the outer conductor over the partial length 1 1 of the support disc ensures, in addition to the mechanical fixing in the longitudinal direction, that the upper limit frequency, reduced due to the influence of the dielectric in sheets, is again increased so as to be approximately greater than or equal to that of the surrounding coaxial system with air insulation.
  • the support of great length compared to the diameter ensures a great transverse mechanical resistance so that the support, in its entirety, is insensitive with respect to the bending forces of the inner conductor.
  • the longitudinal fixing of the segments of dielectric sheets is ensured by the fact that a longitudinal edge is applied at (0) to the end of the slot while the other edge abuts in (p) on the outer conductor of the adjacent coaxial line to be connected.
  • the support is produced as illustrated in the drawing.
  • the additional grooves q visible in FIG. 1 in the split body of the outer conductor serve for the electrical compensation of the field distortions resulting from the jump in diameter D / d 2 to D 1 / d 1 and are dimensioned in the usual way.
