Definitions

  • the present invention relates to a connector for coaxial cable.
  • the Applicant has therefore sought to produce a connector capable of simultaneously ensuring the electrical connection function and the mechanical force recovery function while ensuring absolute sealing and high dielectric strength, for a coaxial cable comprising from the inside to the exterior, a central conductor or core, an electronically insulating coating, an external conductor and a sheath.
  • the connector according to the invention comprises an outer carcass surrounding an insulating screen sleeve placed around a conductive clip whose rear end is connected by means of a hoop to the external conductor of said cable, said conductive clip itself surrounding on the one hand at its front end an annular conductor emerging at the front end of the connector and on the other hand at its middle part two concentric pieces of conical sections between which is fixed the end of said electronically insulating coating, said conical pieces being tightened to the by means of a clamping member abutting on a spacer, an insulating jacket being disposed between said annular conductor, said conductive fastener and an annular part linked to the front part of said outer carcass and surrounding the front end of the connector, a insulating part being further disposed at the front end of said annular connector and a pin connected to the core of said cable, insulating barrels being also provided around said core in the central part of the connector.
  • FIG. 1 therefore shows a cable structure 7 to which the connector according to the invention is adapted, a structure moreover described by the Applicant in French patent application n ° 24 14 243 of January 10, 1978 and in the application of first certificate of addition N ° 24 47 081 of January 18, 1979 for "Electric cable with longitudinal carrying element".
  • Such a structure comprises a central conductor or core 1 formed for example of seven stranded wires of red copper, not shrunk.
  • This conductor is surrounded by an electronically insulating coating formed by 6 cords 2 of the brand "Cef” formed by fine aromatic polyamide fibers of the brand “Kevlar” marketed by Dupont de Nemours, impregnated with a hardenable resin and braided. These strings are embedded in a polyethylene insulation 3 not shown by hatching for clarity of the figure.
  • the external conductor consists of a braid 4 of red copper wires.
  • the assembly is surrounded by a sheath 5 made of polyvinyl chloride or polyethylene.
  • Figures 2, 3A and 3B show the connector according to the invention of the cable 7 arriving at the rear part of said connector.
  • This connector has a generally cylindrical shape. It comprises an external metal carcass 10 secured to a flange 11 pierced for example with 6 bores 12 suitable for receiving the connector fixing bolts (not shown).
  • the carcass 10 surrounds an electrically insulating screen sleeve 13.
  • This sleeve 13 itself surrounds a conductive fastener 14 extending substantially from the middle part to the front part of the screen sleeve.
  • an external cable gland seal 15 cooperates with washers 16, the assembly being arranged between the rear part of the carcass 10 and the sleeve 13. This cable gland 15 is tightened by means of a hollowed out external nut 17 .
  • Said conductive fastener 14 is arranged via its front end around an annular conductor 18 opening out at the front end of the connector and, via its middle part, it secures two pieces of concentric conical sections 19 and 20.
  • an internal gland seal 21 cooperates with washers 22, the assembly being disposed between the rear part of the sleeve 13 and the cable 7; this joint is tightened by means of an internal nut 23.
  • the figures also show a guide part 24 arranged around the cable 7, inside the recess of the nut 17.
  • the object of such a part is to avoid any bending stress on said cable.
  • Reference 25 designates a part suitable for assu rer clamping of the conical parts 19 and 20, this part 25 also coming into abutment on a spacer 26 by means of a flexible washer 27 or a stack of metal washers whose exact length is defined at the time of mounting the connection and thus makes it possible to make up for the game as much as possible.
  • insulating barrels such as 35, 36 and 37 are provided in contact with and around the core 1 of the cable (not shown) in the center of the connector.
  • connection of the various components of the cable 7 to the connector device according to the invention is carried out as follows:
  • the cable 7 is introduced into the rear part of the connector.
  • the central conductor or core 1 (not visible in the figures) is connected directly to pin 34 of the front of the connector.
  • the ends of the Kevlar strings 2 are secured between the parts of conical section 19 and 20, a polymerizable insulating compound 38 being advantageously cast in spaces defined by said parts 19 and 20, the fastener 14, the part 25, and the insulating guns 35 and 37, a cannula 40 also being provided to hold the strings of Kevlar 2.
  • this cannula 40 one end of which is inserted under the braid 4 of the cable, also aims to mechanically reinforce said cable thereby preventing it from being crushed under the pressure exerted by the seal 21. It also ensures the continuity of the screen and the preservation of the impedance.
  • end of the braid 4 is hooped and welded to the rear end of the conductive clip 14.
  • sheath 5 it is stopped substantially at the end of the cannula 40 and held by the hoop of the braid 4.
  • a screen sleeve 13 ensures, in addition to the separation of the potentials, the transmission of the mechanical compression force, this force possibly being at least 2000 kg.
  • gaskets and cable glands makes it possible to seal it at external pressures of the order of 100 bars minimum.
