Definitions

  • the invention relates to an arrangement of contact pairs of double lines and lines of a multi-core cable to reduce crosstalk.
  • the invention is therefore based on the problem of an arrangement of contact pairs of double lines and lines of a multi-core cable create that compact and easily accessible with minimal crosstalk are arranged.
  • the magnetic crosstalk from the first double line 1, 2 to a second double line 3, 4 is directly proportional to the mutual inductance M of this arrangement.
  • the surface integral represents the magnetic flux that passes between the two conductors 3, 4.
  • the vectorial electric field E can also be described by the scalar potential, the potential lines being perpendicular to the electric field lines E.
  • the two conductors 3, 4 must then be arranged on an equipotential surface of the electrical potential. Since the electrical and magnetic field lines E and H are perpendicular to one another, the course of the potential lines is identical to the course of the magnetic field lines H. This in turn means that with line conductors, an arrangement with magnetic decoupling also has electrical decoupling. Due to the finite extension of the lines, the electric field E is distorted near the line, since the surface represents an equipotential surface. However, these deviations are negligible for larger distances.
  • the magnetic field H of the double line 1, 2 is shown, the contact distance of the lines 1, 2 a. 2 shows possible arrangements of the second double line 3, 4, in which the contact distance is also a. There are therefore an infinite number of possible arrangements of the double lines 3, 4, in which the area F 3, 4 spanned by the lines 3, 4 is parallel to the area F 1, 2 and the distance between the contact pairs 1, 2 and 3, 4 is the same size in each case, since the double line 3, 4 is located on a magnetic field line H, the two double lines 1, 2 and 3, 4 are both electrically and magnetically decoupled.
  • FIG. 3 shows a contact arrangement for a 4 x 2 connector.
  • the distance of the lines of each double line 1, 2 or 3, 4 or 5, 6 or 7, 8 is a.
  • the outgoing conductors 1, 3, 5, 7 and the return conductors 2, 4, 6, 8 each in one plane, the distance between a return conductor 2, 4, 6 to the neighboring outgoing conductor 3, 5, 7 is also a.
  • the resulting one Angle ⁇ can be calculated using a calculation with the aid of FIG. 4 calculate as follows:
  • the angle ⁇ can be calculated from the X coordinate of the conductor 3:
  • a multi-core cable can be constructed, for example, as a ribbon cable. in which the adjacent line pairs are arranged on an electrical equipotential line of a line pair.
