  • a connector of this type in which the cores and the ground braids are the cores and the ground braids of two sections of coaxial cable whose ends are equipped with said connector elements, is described for example in FR-A-2 660 489.
  • Such a connector if it is satisfactory in terms of the assembly and the electrical connection which it produces, has the drawback that the disconnection between the two elements can only be achieved by exerting a force of separation of the two elements; very often, especially when this connector is used to connect an antenna cable, in particular on board a motor vehicle, the two elements are not easily accessible and the user or the fitter, to carry out the disconnection, pulls on the cable itself, thus risking, in the long run, the reliability of the assembly.
  • the object of the invention is, above all, to provide a connector which meets better than hitherto the various requirements of practice and which, while allowing good contacts to be established, ensures a reliable mechanical connection between the two elements and includes means for simple unlocking of the connection when a disconnection of the two elements is necessary, while remaining simple mounting and assembly and economical manufacturing.

  • the element 10 further comprises a tubular metal part 14, concentric with the spindle 13 and kept separated from it by the core 15.
  • the tubular part 14 is visible alone in FIGS. 3 and 4.
  • a crimping 19 ensures the anchoring of the core 15 in the part 14 which, at the rear of this core, is extended by an appendage 32 of smaller diameter crimped (not shown) on a stripped end region of the braid 12, which ensures the electrical connection between the tubular part 14 and the ground braid 12.
  • This appendage 32 is also crimped (not shown) on the insulating sheath 33 surrounding the ground braid 12.
  • the envelope 17 is shown alone in FIGS. 7 to 9.
  • the anchoring of the metal part 14 in the envelope 17 is ensured by a press fit of the envelope 17 in the metal part 14 and positioned axially by means of a collar 34 projecting from the outer surface of the part 14 clipped into a groove 36 of the envelope 17.
  • Longitudinal ridges 35 provided on the outer surface of the part 14 extend from the collar 34 and allow the envelope 17 to be guided and centered, all by facilitating the press fit of the envelope 17 in the metal part 14 and ensuring their joining in rotation.
  • the envelope 17 has, at its front end, on its internal wall, radial projections 160 towards the inside, and regularly distributed over the periphery. These projections 160 constitute a latching means 16 complementary to a latching means 26 provided on the other connector element 20.

  • the tubular metal part 24 is shown alone in FIGS. 5 and 6.
  • the external diameter of the metal tubular part 24 is such that this part can enter the part 14 by compressing a helical spring 40 housed in the metal tubular part 14 of the element 10, which establishes a good electrical contact between the parts 14 and 24.
  • the pin 13 enters the socket 23.
  • the tubular part 24 comprises, towards the rear, the latching means 26 formed by a sort of flange 39 which projects radially with respect to the cylindrical surface of the part 24.
