Abstract

An electrical cable includes at least two wires extending side by side along a longitudinal cable direction. The wires are electrically insulated from each other by an insulation. An electrical device is in electrical contact with the respective wires. A flexible carrier surrounds the wires annularly in cross section, and the electrical device is mounted on an inner side of the flexible carrier which faces the wires.

First claim

What is claimed is:

1. An electrical cable comprising:
at least two wires extending side by side along a longitudinal cable direction;
an insulation by which the wires are electrically insulated from each other;
an electrical device that is in electrical contact with the respective wires; and
a flexible carrier which surrounds the wires annularly in cross section, the electrical device being mounted on an inner side of the flexible carrier which faces the wires.

2. The electrical cable as recited in claim 1 , wherein the electrical device is a flexible semiconductor device.

3. The electrical cable as recited in claim 1 , further comprising electrical conductors disposed on the flexible carrier, each of the electrical conductors extending from the electrical device to a respective one of a plurality of electrical connecting elements by which the electrical device is in electrical contact with the wires.

4. The electrical cable as recited in claim 3 , wherein the electrical connecting elements are arranged on the flexible carrier as rigid electrical connection points by which the flexible carrier rests against the wires.

5. The electrical cable as recited in claim 4 , wherein the electrical connecting elements are formed on the flexible carrier as rigid projections extending from the carrier toward the wires.

6. The electrical cable as recited in claim 3 , wherein the electrical connecting elements each have a passage in alignment with an associated through-hole in the flexible carrier.

7. The electrical cable as recited in claim 6 , wherein the flexible carrier is fixed to the wires through the passages in the connecting elements.

8. The electrical cable as recited in claim 7 , wherein the flexible carrier is fixed by material-to-material bonding to the wires through the passages in the connecting elements.

9. The electrical cable as recited in claim 3 , wherein two of the connecting elements are provided and are on the flexible carrier spaced from each other along the longitudinal cable direction such that each of the wires enclosed by the flexible carrier are contacted.

10. The electrical cable as recited in claim 1 , wherein at least one of the wires has a discontinuity at a location at which the electrical device is disposed, and wherein the discontinuity is bridged by the electrical device.

11. The electrical cable as recited in claim 1 , wherein the insulation of the wires is partially removed at a location at which the electrical device is disposed so as to permit electrical connection of the electrical device.

12. The electrical cable as recited in claim 11 , wherein the insulation of the wires is removed at the location at which the electrical device is disposed along an entire longitudinal extent of the flexible carrier in the longitudinal cable direction.

13. The electrical cable as recited in claim 11 , wherein the flexible carrier bears inwardly against the wires at the location at which the electrical device is disposed and the insulation of the wires is partially removed.

14. The electrical cable as recited in claim 1 , wherein a longitudinal extent of the flexible carrier along the longitudinal cable direction is less than 10% of a longitudinal extent of the electrical cable.

15. The electrical cable as recited in claim 1 , further comprising a cable shield which surrounds an outside of the wires, wherein the flexible carrier is disposed between the wires and the cable shield.

16. The electrical cable as recited in claim 1 , wherein the electrical device is flexible and rolled with the flexible carrier about the at least two wires.

17. The electrical cable as recited in claim 1 , further comprising at least two electrical conductors arranged on the inner side of the flexible carrier extending from the electrical device, each of the electrical conductors being in electrical contact with one of the at least two wires.

18. The electrical cable as recited in claim 17 , wherein each of the electrical conductors is electrically connected to a respective one of the at least two wires by a connecting element which is in electrical contact with the respective one of the at least two wires and by a material-to-material bond which extends in each case through a passage in a respective one of the connecting elements.

19. The electrical cable as recited in claim 18 , wherein the material-to-material bond is a solder introduced in each case into the passage of the respective one of the connecting elements through a respective through-hole in the flexible carrier which is aligned with the passage of the respective one of the connecting elements such that the flexible carrier is fixed to the wires.

20. A method for manufacturing an electrical cable having an electrical device disposed therein, the method comprising:
at least partially removing insulation from at least two wires of the electrical cable in a region of the electrical cable at which the electrical device is to be arranged;
mounting the electrical device on an inner side of a flexible carrier which will face the wires in an assembled state of the electrical cable;
rolling the flexible carrier having the electrical device mounted thereon around the at least two wires, or sliding the flexible carrier in a rolled state together with the electrical device mounted thereon over the at least two wires; and
introducing a material-to-material bonding through a through-hole in the flexible carrier and into a passage in alignment with the through-hole and extending through a connecting element which is in electrical contact with a respective one of the wires.
