Definitions

  • the present invention relates to a method for producing a coaxial connector element of the hermetic type with direct sealing, that is to say comprising: a tubular body having an internal cavity; a rod immobilized axially in said body by a bead of dielectric material, in particular of glass, said axial rod projecting from the end of said body closed by said bead; a central contact having an axial recess for its engagement around said rod inside said body; and an insulator between said central contact and the wall of the cavity of said body.
  • a first method currently known for immobilizing the central contact on the axial rod consists in making a weld in the vicinity of the end of the central contact. Due to the location of the area where the welding is to be carried out, this is done in fact blind, so that, in practice, its quality is difficult to control. In addition, this solder is not reliable because it must, during use of the connector element withstand temperatures greater than 250 ° because usually the other end of the axial rod when the element connector is mounted in a housing is welded using temperatures above 250 °.
  • a second method currently known consists in using a mechanical means, such as pliers, in an attempt to immobilize the central contact on the axial rod. This process does not ensure good immobilization in translation.
  • the present invention thus proposes to provide a method for producing a connector element by which an effective immobilization, both in translation and in rotation, of the central contact on the axial rod is ensured in the cavity of the body of the connector by mechanical means, without heating, the central contact being also perfectly positioned in the body of the connector element.
  • the central contact can, if necessary, be dismantled and replaced if it is defective, the same characteristics being able to be obtained with a new contact.
  • the method according to the invention is characterized in that an annular shoulder projecting inwardly in the axial recess is produced on said central contact in the vicinity of its end intended to be engaged around said axial rod. is provided with the central contact, which one engages in said body said central contact around said axial rod, which one embeds said shoulder of the central contact in said rod by engaging around the central contact a tubular piece capable of exerting on him under the action of a peripheral sleeve in the area having said shoulder, peripheral forces directed inward against the rod, which is removed from said tubular piece, and that an insulator is placed in said body around the central contact.
  • the tubular part has an internal cylindrical bearing bearing against the central contact and an external frustoconical bearing on which slides a frustoconical bearing corresponding to the sleeve engaging externally around said part.
  • the latter comprises at its end, in front of said bearing surfaces, front bearing surfaces abutting against the internal bottom wall of the cavity of the body of the connector element to ensure exact positioning of the shoulder of the connector. central contact with respect to the axial rod.
  • the shoulder of the central contact is preferably made at the bottom of a chamfer formed in the end face of this central contact.
  • the shoulder can be achieved by any means such as by machining or advantageously by embossing using a tool with a conical tip engaging in the chamfer and pushing the material of the central contact until the annular shoulder projecting inwards.
  • FIG. 1 shows a connector element produced according to the invention.
  • the connector element comprises a metal body 1 in which a metal rod 2 is immobilized axially by means of a glass bead or similar dielectric material 3, sealed to the metal parts. As can be seen in FIG. 1, the axial rod 2 projects from the end of the body closed by the glass bead 3.
  • a central contact 4 which has an axial recess 5, formed by two sections of different diameters, separated by a frustoconical recess 5a, and in the vicinity of its end, an annular internal shoulder 6 protruding into the recess 5 and penetrating according to the present invention into the rod 2.
  • the opposite end 7 of the central conductor must be perfectly positioned relative to a mechanical reference plane materialized at 8. This positioning must be respected with precision for optimal quality of microwave electrical connection with a complementary central contact (not shown) of a connector element intended to be assembled with the connector element according to the invention.
  • an insulator 9 Between the central contact 4 and the wall of the central cavity of the body 1 is placed an insulator 9.
  • FIGS. 2 to 4 describe a particular preparation of the end of the central contact 4 for the production of the connector element shown in FIG. 1.
  • a chamfer 11 is machined in the end face 10 thereof, for example at 120 °.
  • a tool 12 with a conical tip at 120 "or slightly less, which, by turning, pushes the material from the central contact 4 until it forms an annular shoulder 6, as shown in FIG. 3, this shoulder projecting inwards into the recess 5.
  • a plurality of longitudinal slots 12 are then produced (FIG. 4) over part of the length of the central contact 4 from its end face 10 in order to impart a certain radial elasticity to the central contact 4 in its end zone.
  • the central contact 4 is first positioned precisely with respect to the connector body 1 at the end 7 of the central contact with respect to the mechanical reference plane 8. places around the central contact 4 a tubular part 14 which has a cylindrical internal bearing 15 and a frustoconical external bearing 16, as can be seen in FIG. 8.
  • This tubular part 14 has longitudinal slots to allow its deformation in the radial direction.
  • This tubular part 14 further comprises at its front end of the bearing surfaces 15 and 16 of the front bearing surfaces 17 abutting against the internal bottom wall of the central cavity of the body of the connector element.
  • the connector element is then completed, after disengagement of the sleeve 18 and then of the part 14 by the introduction of an insulator 9 which can be seen in FIG. 1.
  • FIG. 8 there is shown schematically the operation to extract a central contact 4.
  • a tool 20 shaped to open radially towards the outside, as shown schematically by the arrows in FIG. 10, the end of the central contact 4 in order to free the shoulder 6 from its imprint in the rod 2 or from the groove 13 with which this rod can be provided. It then suffices to pull on the rear end of the central contact 4 to extract the latter.
