  • the metal body 12 has, near its rear end, an external thread 16 onto which is screwed a nut 18 for mounting a closure plug 20 of the rear wiring face 14 of the connector element 10.
  • the mounting nut 18 is mounted to rotate freely on the free front edge 22 of the closure plug 20 by radial crimping of a folded edge 24 which cooperates with a radial groove 26 formed on the outer peripheral surface of the front edge 22 of the plug closing 20.
  • the front edge 22 of the plug 20 has axial teeth 28 which cooperate with corresponding axial teeth 30 formed at the rear end of the body 12 to immobilize the closure plug 20 in rotation relative to the body 12 and this in a determined angular position. .
  • the mounting nut 18 is coated with a cap of insulating material 19.
  • the closure plug 20 is a metallic element of generally cylindrical shape comprising a lateral skirt 32 and a rear transverse bottom 34.
  • Ground continuity between the metal body 12 of the connector element 10 and the closure plug 20 is ensured by the metal mounting nut 18 and by the teeth 28 and 30 held in contact and by the tightening of the nut .
  • the hollow closure cap 20 defines an interior chamber 36.
  • the lateral skirt 32 In the vicinity of its front edge 22, the lateral skirt 32 has two orifices 38 which are coaxial and diametrically opposite with respect to the general axis X-X common to the metal body 12 and to the closure plug 20.
  • Each of the lateral openings 38 is provided to allow the passage of an electrical cable (not shown), the wires of which must be wired to the rear face 14 of the connector element 10.
  • each of the orifices 38 is a tapped hole which is designed to receive the threaded end 40 of a metal extension 42 of the body 12 of the connector element 10, only one of which is shown in FIG. 1.
  • the extension 42 is equipped with an external insulating sleeve 44 which allows the shielding braid of the electric cable to be connected to the metallic mass of the extension 42 and therefore to the metallic body 12 by means of the metal body of the closure cap 20.
  • the metal closure cap 20 is enveloped by an insulating sleeve46 which substantially follows the external contour of the closure cap 20.
  • the insulating sleeve 46 has a side skirt 48 and a rear transverse bottom 50.
  • the lateral skirt 48 comprises two diametrically opposite lateral ferrules 52 which each define a lateral orifice 54 for the passage of the body of an extension 42.
  • the extenders 42 screwed into the threaded holes 38 thus ensure the axial immobilization and rotation of the insulating sleeve 46 relative to the metal body of the closure plug 20.
  • the covering of the insulating sleeve 44 of the extension 42 with the ferrule 52 also ensures the continuity of the external insulation of the metallic masses.
  • the rear part of the interior chamber 36 is designed to receive a cartridge 56 supporting an electrical or electronic component (s).
  • the cartridge 56 is an element of electrically insulating material of generally cylindrical shape comprising two diametrically opposite flats 58 which are provided to cooperate with two corresponding flats 60 formed in the inner wall of the side skirt 32 of the plug 20.
  • the cartridge 56 comprises two main branches 62 and 64 which extend axially from its front transverse face 66 and which delimit between them an internal housing 68.
  • Each of the two branches 62 and 64 has an axial bore opening 70, 72 respectively.
  • Each of the bores 70, 72 constitutes a cell which receives an electrical contact element 74, 76.
  • Each electrical contact element 74, 76 has a generally cylindrical shape and constitutes a terminal respectively for the direct or indirect connection of the earth to the metallic mass of the plug 20.
  • the first connection terminal 74 is a direct connection terminal to the metal ground. To this end, a portion 78 of the contact element 74 is force-fitted and with electrical contact into a corresponding hole 80 formed in the bottom 34 of the plug 20.
  • the outer end 82 of the electrical contact element 74 projects outside the insulating sleeve 46, through which it passes through an orifice 84.
  • connection terminal 74 The inner end 86 of the connection terminal 74 includes a tapped hole 88 intended to receive a screw for fixing a connection terminal.
  • the second terminal 76 is an indirect connection terminal to the metallic mass of the plug 20, that is to say with the interposition of a capacitor.
  • the end portion 90 of the electrical contact element 76 passes through the bore 93 of an electrical insulation sleeve 92 produced integrally with the bottom 50 of the insulating sleeve 46.
  • the sleeve 92 extends itself through a hole 91 in the bottom 34 of the plug 20.
  • connection terminal 76 Its free outer end 95 is accessible to allow connection of the ground via the connection terminal 76.
  • connection terminal 76 has a tapped hole 96 intended to receive a screw for fixing a connection terminal.
  • this capacitor (not shown) is received in the internal housing 68 of the cartridge 56 and its two connecting conductor wires, the ends of which are fitted with connection lugs, pass through the transverse partition 98 of the cartridge 56, arranged near its front face 66, by two orifices 100 and 102.
  • Each of the pods 104, 106 has a transverse tab 108, 110 which extends transversely opposite a portion of the transverse partition 98 of the cartridge 56.
  • the legs 108 and 110 ensure the axial immobilization in position of the cartridge 56 in the bottom of the interior chamber 36.
  • connection lugs 104 and 106 In order to connect the body 12 of the connector element 10 to earth via the closure plug 20 to earth, the operator must equip the latter with a cartridge 56 in which he has previously set up a then connect the two connection lugs 104 and 106 to the connection terminals 74 and 76.
  • connection terminal that he wishes to use, that is to say - say either the direct connection terminal 74 which is for example marked with the letter A on the rear face 50 of the insulating sleeve 46, or the terminal 76 for indirect connection through the capacitor which is for example marked with the letter B on the rear face 50 (see FIG. 6).
  • the connector element is an end of transmission line element
  • the electronic circuit is for example produced on a printed circuit board 112 which is shown diagrammatically in silhouette in FIG. 5.
  • the parallel edges 114 and 116 of the printed circuit board 112 are received in two parallel slides 118 and 120 formed inside the internal housing 68.
  • connection wires to the circuit 112 can pass through the partition 98 through a rectan passage gular 122 provided for this purpose in the partition 98.
  • the line termination circuit can for example comprise three connecting conductive wires, one of which is connected directly to earth by a connection terminal which is screwed onto the inner end 86 of the connection terminal 74 and two other wires of transmission which are wired to the rear side of the connector element 10.
