  • the connector 100 or the contact element system 50 arranged in the connector 100 includes both unmodified contact elements (ie contact elements without an adaptation structure and/or contact elements with an unmodified adaptation structure) and modified contact elements (ie contact elements with a modified adaptation structure).
  • the contact element system 50 includes at least two differently modified contact elements.
  • the contact element system 50 as in the Figure 6a shown include four unmodified contact elements (each without an adaptation structure) and six contact elements, each with a modified adaptation structure.
  • the contact element system 50 it would also be possible for the contact element system 50 to include at least two contact elements with differently modified adaptation structures.
  • Two each Contact elements 10b arranged one above the other or next to one another, each of which has a modified adaptation structure form a differential contact element pair 15 (“Differential Pair”).
  • the connector or the contact element system 50 comprises four unmodified contact elements (each of which have no adaptation structure), and six modified contact elements, each with a modified adaptation structure.
  • the modified adaptation structures of the six modified contact elements each have a flat surface.
  • the six modified contact elements include three contact element pairs 15 (in particular "differential pairs"), each with two modified contact elements, the two modified contact elements of each contact element pair 15 being arranged parallel to one another in such a way that the flat surfaces of the adaptation structures of the two modified contact elements of each contact element pair 15 are facing each other.
  • Two modified contact elements of a first contact element pair of the three contact element pairs are also arranged rotated by 90° relative to each of the remaining modified contact elements of the other two contact element pairs with respect to the flat surfaces.
  • the four unmodified contact elements viewed in a section perpendicular to the longitudinal axes of the unmodified contact elements, are arranged at the corners of a rectangle.
  • the four unmodified contact elements are arranged such that their axial end sections E1 (see, for example, Figure 1c ) form the corners of a rectangle.
  • the Figure 6b shows a schematic drawing of a section of the connector from Figure 5 in a perspective rear view.
  • the end sections E2 or the solder connections 8 of the plug contact elements 10a see also the Figures 1a and 1b .
  • the Figure 6b Only two of the ten connected cables 18 are shown, while the remaining eight cables are hidden.
  • the two modified contact elements 10a of each pair of contact elements 15 each have a predetermined distance D at the end sections E2 or the solder connections 8.
  • the contact elements 10a By arranging the contact elements 10a in such a way that in the contact element pairs 15 the flat soldering surfaces 8 of the two contact elements involved are facing away from each other, it can advantageously be ensured that the distance D always remains the same regardless of the solder introduced when soldering the strands. This advantageously ensures electrical properties that are as constant as possible, such as a capacitance and/or impedance of the plug connector 100 or the contact element system 50 arranged in the plug connector 100 that is as constant as possible.
