Abstract

A data cable has a specially formed stranded conductor, as a result of which the transmission properties of the data cable are significantly improved. The stranded conductor is surrounded by insulation and has an unpressed assembly composed of a plurality of individual wires which are of a same type and being embodied as external wires and being disposed around a center. The external wires are embodied with a non-round cross section, with a result that when viewed in cross section an extent of the external wires increases radially outward from the center.

First claim

The invention claimed is:

1. A data cable, comprising:
a data conductor having a stranded conductor surrounded by insulation, said stranded conductor having an unpressed assembly composed of a plurality of electrically contacted individual wires which are of a same type and being embodied as external wires and being disposed around a center, said external wires each being embodied with a non-round cross section, with a result that when viewed in cross section an extent of said external wires increases radially outward from the center, said stranded conductor being free of a central conductor.

2. The data cable according to claim 1 , further comprising a shield surrounding said data conductor.

3. The data cable according to claim 2 , wherein said data cable is a coaxial cable in which said stranded conductor and said shield are disposed concentrically.

4. The data cable according to claim 1 , wherein said data conductor is one of two data conductors forming a wire pair.

5. The data cable according to claim 1 , wherein said stranded conductor has an empty center.

6. The data cable according to claim 1 , further comprising a functional element disposed in the center of said stranded conductor.

7. The data cable according to claim 6 , wherein said functional element is a strain relief element.

8. The data cable according to claim 6 , wherein said functional element is a latent heat accumulator.

9. The data cable according claim 1 , wherein said external wires each have a triangular cross-sectional shape.

10. The data cable according to claim 1 , wherein said external wires have a cross-sectional shape with rounded corners.

11. The data cable according to claim 1 , wherein said external wires have a cross-sectional shape with outwardly bent sides.

12. The data cable according to claim 1 , wherein in each case two adjacent ones of said external wires touch one another in a punctiform fashion.

13. The data cable according to claim 1 , wherein in each case two adjacent ones of said external wires touch one another over a surface.

14. A stranded conductor comprising:
an unpressed assembly composed of a plurality of individual wires which are of a same type and are embodied as external wires and are disposed around a center which is free of a central conductor and having a central void surrounded by said individual wires, said external wires are each embodied with a non-round cross section, with a result that when viewed in cross section an extent of each of said external wires increases radially toward an outside from the center.
