  • the reshaping can advantageously take place during the pressing of the outer conductor contact element 8 on the support sleeve 11.
  • the Figures 8 to 12 show a second embodiment of the outer conductor contact element 8 according to the invention, the Figures 8 and 9 a detail of the outer conductor contact element 8 in an individual representation and the Figures 10 to 12 the outer conductor contact element 8 in a partially assembled state ( Figure 10 ) and in an assembled state ( Figures 11 and 12 ) on the pre-assembled cable 2.
  • the fixing stop 15 is formed by a material recess 17 made in the outer conductor contact element 8.
  • the material recess 17 is, however, introduced into the outer conductor contact element 8 in such a way that the outer conductor contact element 8 forms a tab 18 connected on one side, the free, plug-side edge of the tab 18 forming the fixing stop 15.
  • the fixing stop 15 can finally be formed, which is able to secure the outer conductor contact element 8 in a form-fitting manner along the longitudinal axis L of the outer conductor contact element 8 or the connector arrangement 1.
  • Figures 13 to 16 show a third embodiment of the outer conductor contact element 8 according to the invention.
  • Figure 13 shows a detail of the outer conductor contact element 8 in an individual illustration.
  • the Figures 14 and 15th show the outer conductor contact element 8 during the progressive assembly or during the pressing process on the support sleeve 11.
  • Figure 16 shows the outer conductor contact element 8 in its assembled state.
  • the fixing stop 15 in the third exemplary embodiment is not formed by a material recess 17, but by a separate stop element 20 fastened to the inner wall 19 of the outer conductor contact element 8.
  • the stop element 20 can be fastened to the inner wall 19 of the outer conductor contact element 8, for example by means of clinching or some other method, preferably in a form-fitting manner. This is preferably done in the still unmounted state of the outer conductor contact element 8 or before its assembly.
  • the separate stop element 20 is designed as a sheet metal element.
  • the stop element 20, however, can also be designed as a wire part or as some other stop element 20.
  • Figures 17 to 20 a fourth embodiment of the outer conductor contact element 8 according to the invention
  • Figures 17 and 18 show a detail of the outer conductor contact element 8 in an individual representation.
  • Figure 19 shows the outer conductor contact element 8 in a partially assembled state on the pre-assembled cable 2;
  • Figure 20 shows the outer conductor contact element 8 in an assembled state.
  • two fixing stops 15 are formed in the outer conductor contact element 8 by embossings 21 made in the outer conductor contact element 8 in the unmounted state of the outer conductor contact element 8.
  • the embossings 21 are preferably introduced into the outer conductor contact element 8 as part of the punching and bending process.
  • the embossments 21 are formed in the outer conductor contact element 8 as partially annular webs. In principle, any number of embossings 21 can be provided, for example only a single embossing 21. It is also possible to provide an embossing which forms a completely ring-shaped circumferential web.
  • any number of fixing stops 15 can be provided in the outer conductor contact element 8.
  • two partially annular webs are described in the fourth embodiment in order to form two fixing stops 15.
  • each of the fixing stops 15 shown can be present several times in each exemplary embodiment, with combinations of different types of fixing stops 15 also being possible within the scope of the invention.
