  • an EMC labyrinth is formed by covering the first slots 81 of the outer conductor 8 by means of the extensions 46 of the carrier body 4, in particular because of the flanged design of the extensions 46 (which are mushroom-shaped in cross section) in order to prevent electromagnetic waves from penetrating into to prevent the space surrounded by the outer conductor 8.
  • Figure 6A shows an exploded view of the electrical connector from the Figures 1A and 1B together with the components directly adjoining it on the cable side, before bending the support sections 43, 44 of the carrier body 4.
  • the cable side is in Figure 6 the electrical cable 1 with the wires 11, 12 and their respective core (electrical line 11a or 12a) as well as with the drain wires 21, 22 and with the cable jacket 15.
  • the end of the electrical cable 1 facing the electrical connector is to be provided with the support crimp 16 already described, to which in turn a potting 18 is applied.
  • the carrier body 4 is designed as with the Figures 1A and 1B described. It forms an inner core of the electrical connector, on which the electrical component 5 (with its housing 50) is arranged, with the electrical contact elements 31, 32; 71, 72 is connected via wires 61, 62, 63, 64.
  • the plug connector is surrounded by the outer conductor 8 with the first and second slots 81 and 82, the space between the carrier body 4 - with the exception of the support sections 43, 44 leading to the outside - and the outer conductor 8 being filled by a potting compound 85.
  • the assembly of the connector including the connection of the electrical cable 1, can be described as follows: First, the electrical cable 1 is provided and at its free end, to which it is to be connected to the associated electrical connector, with the Support crimp 16 provided. On the electrical cable 1, its drain wires 21, 22 have already been separated, as shown in FIG Figures 2A and 2B described.
  • the lead frame is then provided, from which the carrier body 4 and the cable-side and output-side contact elements 31, 32; 71, 72 together with the further components 33, 34; 73, 74 are formed.
  • the stripped free ends of the wires 11, 12 of the electrical cable 1, at each of which the associated core is exposed in the form of an electrical line 11a, 12a, are each in contact with a cable-side contact element 31, 32 via its receptacle 33, 34 Intervention.
  • An additional connection is made at the respective contact or engagement area, preferably by material bonding, for example by soldering or welding.
  • the electrical component 5 is arranged on the carrier body 4 and fixed there (cohesively) and via the wires 61, 62, 63, 64 to the cable-side and output-side contact elements 31, 32; 71, 72 electrically connected.
  • the components defining the interior of the electrical connector namely the carrier body 4 and the contact elements 31, 32; 71, 72 with the further associated components 33, 34; 73, 74 and the electrical component 5 arranged on the carrier body 4, including the associated wires, are then provided with the insulating encapsulation 85 by injection molding to form the channels 86.
  • the outer conductor 8 is pushed (by means of the first slots 81) over the aforementioned components of the electrical connector, the outer conductor 8 being guided through the carrier body 4, as described above Figure 3A explained. Then the filler strands 21, 22 are compared with their free end sections 21a, 22a Figures 5A and 5B , are introduced into the second slots 82 of the outer conductor 8 provided for this purpose and are fixed there in a materially integral manner, for example by soldering, welding or gluing. And there are the support portions 43, 44 of the carrier body 4 to form the annular configuration from the Figures 1A and 1B bent over as in Figure 6B shown, and optionally also cohesively, for example by welding, fixed to the outer conductor 8.
  • the transition between the electrical cable 1 and the connector is provided with the encapsulation 18, which in particular encloses the support crimp 16.
