  • the mating component is a connector 35 (best seen in Fig.
  • the center conductor is a conductor pin 36 thereof, as explained in more details below, see Fig.2 .
  • the rearward fingers 20 are contractable between an insertion position allowing insertion of a center conductor of a mating component and a gripping position, in which the center conductor is gripped.

  • the center conductor is a center conductor thereof as explained in more details below.
  • the connector 1 comprises a ring-shaped clamping member 21 centrally arranged within the forward end of the cavity adjacent a forward end of the forward fingers 19.
  • the clamping member 21 is shown in more details in Figs. 3-5 .
  • the clamping member 21 is made of a dielectric material, preferably a plastic material, and has a first rearwardly facing side 22 and an opposite second forwardly facing side 23 and further a central aperture 24 dimensioned for receiving the above-mentioned center conductor pin 36 of a mating connector 35.
  • the clamping member 21 is arranged axially movable along the axis of the connector body 2, guided by an inner face 25 of an inwardly extending protrusion 26 of the body extension 5 cooperating with an outer surface 27 of the clamping member 21.
