Definitions

  • the wire diameter is 1.6 mm for a wire diameter of approximately 0.64 mm.
  • These cables have one Impedance of 100 ohms.
  • a shield surrounds each pair of wires.
  • a wire diameter of 1.6 mm is disadvantageous because these veins are not without limitation with conventional ones Have the connector systems contacted.
  • Many conventional ones Connector connections are namely insulation displacement connections trained only veins with a maximum Can accommodate a diameter of 1.4 mm. The relatively thick However, wire insulation is necessary to achieve the desired impedance to achieve. The core diameter can therefore not be simply reduce.
  • the intermediate jacket is not only used for stabilization the relative position of the individual wires to each other, but also the stabilization of the shield surrounding the intermediate sheath with regard to their position to the single cores or their leaders.
  • a stabilization of the shielding position to the conductors is advantageous because the distance of the Shielding to the conductors is decisive in the electrical Properties of the cable determined. Therefore it comes down to one exactly defined position of the shield in relation to the Head on. Because of its property as a dielectric (with a much higher dielectric constant than air) in that formed by wire pairs and capacitor The intermediate sheath reduces the capacitor Attenuation of the double line.
  • the intermediate sheath fills the notches between the cables the surfaces of the single wires of the wire pair almost completely from (claim 2) and focuses closely on the single wire insulation, so that a kind of "embedding" of the symmetrically stranded Single cores in the intermediate sheath material trains.
  • the intermediate sheath is so tight the conductor insulation of the single cores, for example when laying the cable in any situation in the specified stranding position remain.
  • the data cable particularly preferably has an all-encompassing one Outer jacket on (claim 5). Even the outer jacket can perform the function of holding several double lines together. The outer jacket also protects against penetration of moisture and additionally improves the mechanical stability and resilience of the data cable.
  • the data cable preferably has one in comparison to one corresponding data cables of the same impedance, for example 100 ohms, but without intermediate sheath, thinner wire insulation on (claim 7).
  • a comparable data cable without an intermediate sheath contains, as already described at the beginning, also a pair of wires and one surrounding the pair of wires Shielding. Comparable data cable in this sense means equal impedance, the impedance of a double line is meant with symmetrical wiring and grounded shield.
  • the thickness of the wire insulation serves to set a certain desired impedance value, on the one hand because they are the distance of the Conductors to each other and the distance between the conductors intended for shielding.
  • Symmetrical wiring means that not the impedance between the two wires on the one hand and shielding is measured on the other hand, but between the wires of a pair of wires.
  • the shield is usually at a different potential than that Single wires, for example to earth potential.
  • a special embodiment provides that the data cable has at least two twisted double lines, which in the essentially identical twist lengths (hereinafter double-line twist lengths called) and opposite twist directions have (claim 11).
  • the group delays are due to different twist lengths adversely affected by conventional cables.
  • the reason for this is the different length of the Wire pairs, e.g. with known DM four.
  • This negative Behavior is improved by the invention or completely eliminated, since the lengths of both (forming a foursome) Wire pairs are the same size.
  • the cross-sectional centers are in this embodiment of the four double lines on the corners a square, in particular a square, a rectangle or a diamond.
  • the four double lines there are two possibilities, namely on the one hand that two double lines with the same double line twist lengths and opposite twist direction opposite corners, on the other hand, that these double lines lie on immediately adjacent corners of the square.
  • the different double line twist lengths are particularly preferred optimized for maximum decoupling (Claim 16).
  • the decoupling is strongly influenced by the Relationships of the double line twist lengths are affected. It on the one hand, there are conditions that require a high level of decoupling of Ensure double lines, on the other hand there are unfavorable Ratios leading to a larger coupling and thus lead to stronger crosstalk. In this embodiment the conditions of the data cable chosen to ensure maximum decoupling.
  • Double lines 4-7 are four Double lines 4-7 in a flexible material 8, for example a plastic, embedded.
  • This flexible Material 8 is nevertheless so dimensionally stable that it provides stabilization the relative position of the double lines 4-7 to each other guaranteed. In particular, it prevents accidental Twisting the double lines 4-7 for example when laying the data cable 1.
  • the flexible material 8 thus forms a further intermediate jacket embedding.
  • This further intermediate jacket embedding essentially fills all gaps between the double lines and therefore stabilizes their relative position to each other.
  • the intermediate jacket embedding helps to maintain it the twist lengths of the double lines as they change the twist, i.e. an additional torsion of the Can prevent double lines.
  • the flexible material 8 not available. Then the position stabilization the double lines 4-7 achieved in that the outer jacket 2 or the overall shield so tight around the double lines 4-7 is created that essentially none Shifting the position of the double lines is possible.
  • the four double lines 4-7 are each in the corners of a square or square.
  • the double lines 4-7 each functional unit is in opposite Corners of the square or - in other words - two (diagonal) opposite double lines form a functional one Unit.
  • FIGS. 4-9 offer different ways to optimize a data cable with very good transmission properties, in particular very good decoupling of each forming a data line Double lines and therefore very little crosstalk.
