This is a constructively preferable solution, since the implementation of such an arrangement is easy to handle. It can also be advantageous, by removing the printed circuit board 3, to effect a reliable galvanic separation of circuits within the plug connector 2. It can also be understood as in the context of the invention to provide a printed circuit board 3, which only ensures reliable galvanic separation between some or all of the contacts 9, 11.

  • circuit board 3 functions only for the forwarding or direct contacting of the cable inner conductors 10 with the plug connector inner conductors 12.
  • the circuit board 3 can only have vias for this purpose.
  • the circuit board 3 and the transmission option then function as a so-called "dummy" element.
  • Figure 7 is one of the Figure 6 A similar embodiment is shown, in which the printed circuit board 3 once again only serves to make contact between the cable inner conductors 10 and the connector inner conductors 12, without providing any further influencing of the signals. However, in this embodiment it is a "crossover" connection, ie a cross-connection of signals and thus one of the Figure 6 different connector assignment.

  • Such a fanning out can be clearly seen in FIGS. 1, 2, 4 and 5.

  • Figure 9 shows a further example of different interfaces 30, 31 on the input side and on the output side, each with a different pitch.

Contact can also be made with a ground conductor of the further printed circuit board 32, if necessary, by means of at least one contact line 33.

  • the thermally conductive layer 29 can comprise epoxy resin. Due to the low thermal conductivity of epoxy resin, the thermally conductive layer 29 can also be enriched with boron nitride and / or aluminum oxide. Accordingly, the required thickness of the thermally conductive layer 29 can largely depend on its composition.
  • epoxy resin instead of epoxy resin, synthetic resin can also be used accordingly. This is also particularly suitable.
  • a connector 2 of the above-described embodiments of Figures 1, 2 and 4 to 10 also be designed in two parts.
