Definitions

  • the invention relates to a ready-made cable that has an adapter.
  • HSD cables high speed data; German: data at a high transmission rate
  • HSD cables of this type have two pairs of data lines which are arranged crossed over one another in a so-called star-quad arrangement and are stranded spirally along the data line.
  • the star-quad arrangement While the stranding of the star-quad arrangement results in a lower packing density, the star-quad arrangement enables less crosstalk between the two pairs of data lines, at least in the lower to medium-high frequency range. In the higher frequency range, the crosstalk between the individual pairs of data lines deteriorates significantly.
  • Cables are therefore increasingly used for the higher frequency range, in each of which two shielded pairs of data lines run parallel, i.e. do not cross over. Shielding each pair of data lines improves crosstalk between pairs.
  • the WO 2012/087956 A2 and the US2010/0183141 A1 disclose in each case a signal line pair with signal lines arranged crossed over one another and a signal line pair with signal lines arranged parallel to one another in order to reduce the crosstalk between two differential signal line pairs.
  • the EP 3 163 688 A1 discloses an adapter for the connection between two pairs of signal lines each having signal lines arranged crossed over one another and two pairs of signal lines each having signal lines arranged parallel to one another.
  • the US 2013/0333913 A1 describes a cable with a plurality of differential signal line pairs arranged in parallel.
  • the object of the invention is therefore to create a device with which cables with parallel and respectively shielded pairs of data lines can be coupled to plug connectors in a star-quad arrangement of the data lines.
  • the two shielded pairs of inner conductors of the cable are not only routed to the two parallel first pairs of contact areas in the first connection area, are routed to the contact areas of the second connection area of the adapter.
  • the first and second contact areas of the first pair of contact areas are each electrically connected via a different inner conductor of the one pair of inner conductors of the cable to the third and fourth contact area of the one second pair of contact areas, while the first and second contact areas of the other first Pair of contact areas are electrically connected via a different inner conductor of the other pair of inner conductors with the third and fourth contact area of the second pair of contact areas.
  • the inner conductors arranged crossed over are each oriented at an angle of between 85° and 95° to one another.
  • the crossed-over inner conductors are preferably each oriented perpendicular to one another.
  • the two inner conductors arranged crossed over one another are preferably routed parallel to one another and parallel to the two parallel inner conductors in the area of the first connection area and the second connection area, in order in this way to achieve as orthogonal an orientation as possible of the two crossed inner conductors in the area of the crossing.
  • the capacitive overcoupling between the two crossed inner conductors in the crossing area is minimized by maximizing the distance between the two crossed inner conductors in the crossing area:
  • the two inner conductors which are arranged crossed over one another are preferably curved in a convex manner in relation to one another. They are therefore at their greatest distance from one another in the middle between the first connection area and the second connection area, ie in the area of the crossing.
  • the minimization of the capacitive overcoupling between the two inner conductors arranged crossed over one another is realized in that in opposite areas of the two inner conductors arranged crossed over one another, material is preferably removed in the area of the crossing and thus the distance between the two arranged crossed over one another Inner conductors is enlarged.
  • the two inner conductors arranged crossed over one another are preferably each routed asymmetrically offset to the associated connecting straight line between the two contact areas of the first and second connection area.
  • the two inner conductors arranged crossed over one another then have their greatest possible distance with regard to minimized capacitive cross-coupling when the two asymmetrical offsets are each 180° out of phase with one another.
  • that inner conductor of the two crossed inner conductors in all three variants preferably has a different diameter than the other inner conductor of the two crossed inner conductors that is spatially closer to the peripheral surface of the cylindrical adapter and thus to the ground shielding surrounding the adapter .
  • that inner conductor of the two inner conductors arranged crossed over one another preferably has a smaller diameter than the respective other inner conductor of the two inner conductors arranged crossed over one another, which is guided spatially closer to the peripheral surface of the cylindrical adapter and thus to the ground shielding surrounding the adapter .
  • the change, preferably the reduction, of the diameter of the inner conductor, which is routed closer to the ground shielding, of the two inner conductors arranged crossed over one another advantageously brings about an optimal value for the capacitive component of the impedance of the adapter between the first and second connection area.
  • the propagation times of the HF signals in these inner conductors are different in each case.
  • the signal components of a differential signal are no longer phase-shifted by 180° after passing through the inner conductor, but can have a different phase shift due to the different propagation times in the two inner conductors and therefore no longer represent an exact differential signal.
  • the inner conductors arranged crossed over one another are each surrounded by a material with a lower permittivity than the inner conductors arranged parallel to one another.
  • the material with the lower permittivity results in a higher propagation speed, with which the greater length of the inner conductors, which are arranged crossed over one another, is compensated for.
  • the adapter 1 has a base body which is rotationally symmetrical with respect to a longitudinal axis 2 and is preferably designed as a hollow cylinder.
  • the preferably hollow-cylindrical adapter 1 has an end face in the region of each of its two end faces.
  • the adapter 1 is preferably made as a plastic injection molded part, for example made of polyethylene or polypropylene.
  • the end face shown on the right represents a first connection area 3
  • the end face shown on the left forms a second connection area 4
  • Both the first connection area 3 and the second connection area 4 each have a number of pairs of contact areas that corresponds to the number of differential signals.
  • Two pairs of contact areas corresponding to the number of differential signals transmitted in an HSD cable are preferably provided on both connection areas.
  • the individual contact areas each cover the entire area of the associated in Figure 1A respectively illustrated bores or recesses in the first connection area 3 or in the second connection area 4 of the adapter 1.
  • the first connection area 3 has two first pairs 5 1 and 5 2 of contact areas, each with a first contact area 6 11 and 6 12 and a second contact area 6 21 and 6 22 .
  • the two first pairs 5 1 and 5 2 of contact areas of the first connection area 3 are arranged parallel to one another.
  • an inner conductor of the cable is electrically connected to a first connecting line 7, for example via soldering.
  • a second connecting line 8 another inner conductor of the same pair of inner conductors of the cable that are shielded from one another is electrically connected to a second connecting line 8 .
  • the first connecting line 7 and the second connecting line 8, which are electrically connected to the same pair of shielded inner conductors of the cable, are identified by common hatching.
  • the first connecting line 7 is led to a third contact area 9 11 of a second pair 10 1 of contact areas in the second connection area 4, while the second connecting line 8 is led to a fourth contact area 9 21 of the same second pair 10 1 of contact areas in the second connection area 4.
  • an inner conductor of a further shielded pair of inner conductors of the cable is electrically connected to a third connecting line 11 .
  • a third connecting line 11 In the second contact area 6 22 further Pair 5 2 of contact areas in the first connection area 3 is another inner conductor of this further shielded pair of inner conductors of the cable with a fourth connecting line 12 is electrically connected.
  • the third connection line 11 and the fourth connection line 12, which are electrically connected to the same pair of mutually shielded inner conductors of the cable, are both shown without hatching.
  • the third connecting line 11 is led to a third contact area 9 12 of a further second pair 10 2 of contact areas in the second connection area 4, while the fourth connecting line 12 is led to a fourth contact area 9 22 of the same second pair 10 2 of contact areas in the second connection area 4.
  • the first, second, third and fourth connecting lines 7, 8, 11 and 12 each represent a bundle of conductive strands, preferably made of copper with a sheath made of a non-conductive plastic.
  • the first, second, third and fourth connecting lines 7, 8, 11 and 12 are in the area of the first and second pairs 5 1 and 5 2 or 10 1 and 10 2 of contact areas either up to the outer boundary or to the inner boundary of the respective contact area associated hole or recess out.
  • the first, second, third and fourth connecting lines 7, 8, 11 and 12 can also end within the bore or recess associated with the respective contact area.
  • the second and fourth connecting lines 8 and 12 which are each arranged parallel to one another, are each at such a distance from one another and from an in Figure 1A not shown, applied to the peripheral surface of the adapter 1 ground shielding, so that the inductive and capacitive overcoupling between the second and fourth connecting lines 8 and 12 is minimized overall.
  • first and third connecting lines 7' and 11' cross each other in such a way that they are oriented at an angle of between 85° and 95° to one another in the crossing area or are preferably oriented orthogonally, ie at an angle of 90°, to one another. In this way, inductive overcoupling is largely avoided.
  • the first and second connecting lines 7' and 11' are in the area of the associated contact areas, i.e.
  • a first variant for minimizing the capacitive cross-coupling in the crossover area between the first and second Connecting line, which are arranged crossed to each other, goes from the Figures 3A, 3B and 3C out: How from the Figures 3B and 3C shows, the representation is in Figure 3A along the longitudinal axis 2 of the adapter by 90° compared to the representation in the previous ones Figures 1A and 2 turned.
  • first and third connecting lines 7" and 11 which are arranged to cross one another, are curved convexly to one another in the third embodiment 1" of the adapter and are therefore at an increased distance from one another in the area of the crossing. Due to the increased distance in the crossover area, the capacitive overcoupling between the first and third connecting lines 7" and 11" is minimized.
  • the first connecting line 7 which is closer to the peripheral surface of the essentially cylindrical adapter 1" and thus closer to the in Figure 3A non-illustrated ground shield is positioned, shows how Figure 3A as can be seen, has a different diameter, preferably a smaller diameter, than the third connecting line 11", which is positioned further away from the peripheral surface of the adapter 1" and thus from the ground shielding.
  • This preferably smaller diameter of the first connecting line 7" results in an optimum value for the capacitive component of the impedance between the first connection area 3 and the second connection area 4 of the adapter 1".
  • FIGS 4A, 4B and 4C A second variant, with which the capacitive overcoupling in the crossover area between the first and second connecting lines, which are arranged crossed over one another, can be minimized is Figures 4A, 4B and 4C shown:
  • an increased distance between the first and third connecting lines 7′′′ and 11′′′, which are each arranged crossed over one another, is realized in that they are each offset asymmetrically to a connecting straight line between the associated contact areas and at an angle of 180° offset from one another.
  • the first connecting line 7′′′ is thus laid asymmetrically in the area of the first contact area 6 11 of a first pair 5 1 of contact areas in the first connection area 3 and in the area of the third contact area 9 11 of a second pair 10 1 of contact areas in the second connection area 4 .
  • the second connecting line 11′′′ is laid asymmetrically in the area of the second contact area 6 12 of a first pair 5 2 of contact areas in the first connection area 3 and in the area of the second contact area 9 22 of a second pair 10 2 of contact areas in the second connection area 4 .
  • the first connection line 7′′′ which is positioned closer to the peripheral surface of the adapter 1′′′ and thus closer to the ground shield, has a changed diameter, preferably a smaller diameter, than the third connection line 11′′′, which is further away from the peripheral surface of the adapter 1′′′ and is therefore positioned further away from the ground shield. In this case, too, the capacitive component of the impedance between the first connection area 3 and the second connection area 4 of the adapter 1′′′ is reduced to the optimum value.
  • a third variant of minimizing the capacitive overcoupling in the crossover area of the first and third connecting lines, which are each arranged crossed over to one another, is described in Figures 5A, 5B and 5C shown:
  • the first and third connecting lines 7′′′ and 11′′′′ of the fifth embodiment 1′′′′′ of the adapter each have a material removal 14 1 and 14 3 in the crossing area. In this way, the distance between the first and the third connection line 7"" and 11"" is increased and the capacitive overcoupling between the first and the third connection line 7"" and 11”” is reduced.
  • the first connecting line 7" has a different diameter, preferably a smaller diameter, than the further away from the peripheral surface of the adapter 1" out third connecting line 11" to the capacitive component of the impedance between to reduce the first connection area 3 and the second connection area 4 of the adapter 1'' to the optimal value.
  • first and third connecting lines which are each arranged crossed over one another, have a greater length than the second and fourth connecting lines, which are each arranged parallel to one another, there is a difference between the signal components of the differential signal in the first and second connecting lines as well as between the Signal components of the differential signal in the third and fourth connecting line to a transit time difference and thus to a phase shift.
  • This phase shift between the signal components of the individual differential signals has the effect that the signal components of the individual differential signals no longer have the phase difference of 180° required for a differential signal after passing through the connecting lines.
  • the propagation speed of the signal components of the differential HF signal in the respectively crossing connecting lines is increased relative to the propagation speed of the signal components of the differential HF signals in the respectively parallel connecting lines.
  • the connecting lines which cross each other, are surrounded by a material with a lower permittivity than the connecting lines, which each run parallel.
  • the sheathing of the electrical conductor of the connecting line or a material additionally surrounding the sheathing of the electrical conductor of the connecting line can be selected with regard to a suitable permittivity.
  • a cable 13 according to the invention is shown, at the end of which an adapter 1 is attached.
  • the cable 13 includes two parallel, shielded pairs of inner conductors. These two pairs of inner conductors are brought up to the two first pairs 5 1 and 5 2 of contact areas in the first connection area 3 of the adapter, which are each implemented as bores or recesses, and passed through these bores or recesses.
  • the inner conductors 8 v and 12 v of the two pairs of inner conductors are routed from the individual second contact areas of the first connection area 3 to the directly opposite second contact area of the second connection area 4, while the inner conductors 7 v and 11 v of the two pairs of inner conductors are routed from the individual first Contact areas of the first connection area 3 to those on the longitudinal axis 2 mirrored first contact areas of the second connection area 4 are performed.
  • the illustrated second, third, fourth and fifth embodiment of the adapter can be equivalently implemented in the adapter attached to the end of the cable 13 according to the invention.
