Definitions
- the invention relates to a cable for transmitting electrical signals with an outer sheath of an electrically insulating material and at least N lines n with N> 2 and NEN, which are arranged within the outer sheath, each line m in total M cores made of an electrically conductive material M> 1 and MEN, where the vein m with me [1,], m EN of the line n with ne [1, N], ne N of a dielectric with a predetermined value for the relative permittivity £ r (m, n)> 1, according to the preamble of patent claim 1.
- a cable for transmitting electrical signals includes cores made of a conductive material, which are each surrounded by an electrical insulator for the purpose of mutual electrical insulation.
- Electrical insulators have dielectric properties and significantly determine the propagation characteristics of the cable for electrical signals that are essentially electromagnetic waves.
- An essential property of dielectric materials or of a dielectric is their permittivity ⁇ .
- the permittivity ⁇ (from lat. Permittere: allow, leave, pass), also called “dielectric conductivity” or “dielectric function”, gives the Permeability of a material for electric fields.
- the vacuum is also assigned a permittivity, since electric fields can set in the vacuum or electromagnetic fields can propagate.
- the relative permittivity ⁇ ⁇ of a medium also called permittivity or dielectric constant, is the ratio of its permittivity ⁇ to that of the vacuum (electric field constant ⁇ ):
- star quad cable To reduce crosstalk of electrical signals from one line to another line within a cable, without the need for an additional shroud for each line in the cable, the so-called star quad cable has been proposed (English: Twisted / Star Quad (TQ); dt .: stranded star quad cable, hereinafter also referred to as "four-star quad").
- TQ Twisted / Star Quad
- dt . stranded star quad cable, hereinafter also referred to as "four-star quad”
- the four-core cable belongs to the balanced copper cables.
- two lines each with two wires, each consisting of an electrically conductive material, are combined to form a cable.
- Each core is surrounded by a dielectric and the four wires are stranded with each other cross-shaped, wherein in the cross section of the star quad cable opposing wires each form a pair of wires, so that the four-wire cable has two wire pairs or lines.
- the stranded four cores are surrounded by a common protective sheath, which may include a braided or foil shield.
- This mechanical design determines the transmission parameters such as near and far crosstalk.
- This type of cable is characterized mainly by the small diameter and the resulting low bending radius.
- Another advantage of the star quad stranding is, in addition to the mechanical stabilization of the arrangement of the conductors or cores relative to each other, the higher packing density than in a pair stranding.
- the quad-core cable is essentially the same as the UTP and STP cable and can be classified accordingly: quad-core non-shielded quad-core cables are referred to as Twisted Quad (UTQ).
- a wire with a jacket of insulating material arranged around it forms a conductor and two wires or conductors each form a line.
- Two in the cross section of the star quad cable opposite conductors or wires form a pair, wherein on a pair in each case an electrical signal is transmitted.
- the four conductors or wires are arranged in the cross section of the star quad at the corners of a square, wherein the conductors or wires of a pair are arranged at diagonally opposite corners.
- the invention is based on the object, a cable og. To improve the type of crosstalk between two lines.
- the values of k (s) can au ch for several subsets of values for s in the range of 1 to (Nj), so that, for example, there are three or more identical values for k (s) within a cable (if N is greater than or equal to 4), the values for k (s) are different for different subsets.
- different lines n may possibly have a different number M of wires.
- the value for M would be a function of n: M (n). This has the advantage that surprisingly results in a lower crosstalk of signals of a line in the other line by the different propagation speed of the electrical signals in the two lines with different value of the permittivity of the dielectrics of the respective wires.
- of about 0.3 is achieved in a particularly simple and cost-producible manner in that the dielectric of the cores of at least one line of the material polypropylene (PP; ⁇ ⁇ "2.1) and the dielectric of the cores of at least one other line of the material polyethylene (PE, e r «2.4).
- An altogether deviating value for the relative permittivity ⁇ ⁇ of the dielectric of the wires of a line with specific setting of a value for k for the deviation of the value for the relative permittivity ⁇ ⁇ of the dielectric of the wires of another line is achieved in a simple way by the dielectric of the cores of at least one line is constructed from a concentric layer structure of two or more dielectric materials with different values for the relative permittivity ⁇ ⁇ .
- the replenishing dielectric is in the range of high field strength densities and is therefore particularly effective.
- a high effect of the dielectric is achieved in that the dielectric of at least one core is arranged in a space between the core and the outer sheath such that this space is parabolic in cross-section of the cable from the adjacent wires. As a result, the dielectric fills a space with high field line density.
- An additional electromagnetic shielding is achieved by additionally providing a sheath made of an electrically conductive material, within which the lines are arranged.
- This screen coat is for example, arranged radially outside or inside the shield shell or integrated in the shield shell (12).

- ⁇ ⁇ ( ⁇ ,]) - k (s) with me [l, M], m EN, je [l, Nl], j EN, se [l, Nj], s EN, where fc (s) e R and k (s) E [ -2.0, -0.01] and c (s) 6 [0.01,2.0], or the index m for the wire runs from 1 to M and is an integer greater than zero, the index j for the line j runs from 1 to (N-1) and is an integer greater than zero, the index s for the line (j + s) runs from 1 to (Nj) and is an integer greater than zero.
