Abstract

A shielded electrical cable includes at least two spaced-apart conductors extending side-by-side along a longitudinal cable direction. An insulation electrically insulates the conductors from each other. A cable shield, together with the conductors, extends along the longitudinal cable direction and annularly surrounds the conductors, as seen in cross section. An electrical device is disposed between the conductors and the cable shield. The electrical device is surrounded by the cable shield and disposed on the conductors such that the electrical device is in electrical contact with each of the conductors.

First claim

What is claimed is:

1. A shielded electrical cable comprising:
at least two spaced-apart conductors extending side-by-side along a longitudinal cable direction;
an insulation by which the conductors are electrically insulated from each other;
a cable shield which, together with the conductors, extends along the longitudinal cable direction and annularly surrounds the conductors, as seen in cross section; and
at least one electrical device disposed between the conductors and the cable shield, the at least one electrical device being surrounded by the cable shield and disposed on the conductors such that the at least one electrical device is in electrical contact with each of the conductors,
wherein the at least one electrical device is disposed in a cable region which is free of electrical connector elements configured for making electrical contact with a mating connector, the cable shield extending across the at least one electrical device in the longitudinal direction of the cable.

2. The cable as recited in claim 1 , wherein the at least one electrical device has a carrier body which rests against each of the conductors via electrical connecting elements formed on the carrier body.

3. The cable as recited in claim 2 , wherein the electrical connecting elements formed on the carrier body are in the form of rigid electrical connection points via which the carrier body rests against the conductors in a fixed position relative thereto.

4. The cable as recited in claim 2 , wherein the carrier body is in the form of a circuit board.

5. The cable as recited in claim 2 , wherein the at least one electrical device is fixedly attached to the conductors via the electrical connecting elements by a material-to-material bond.

6. The cable as recited in claim 1 , wherein the at least one electrical device is fixedly attached to the conductors by a material-to-material bond.

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

8. The cable as recited in claim 1 , wherein the insulation of the conductors is partially removed at a location where the electrical device is disposed so as to form a receptacle for the at least one electrical device.

9. The cable as recited in claim 1 , wherein, at a location where the at least one electrical device is disposed, the conductors, together with the at least one electrical device, are surrounded by a protective layer which is produced separately from the insulation, the protective layer being surrounded by the cable shield.

10. The cable as recited in claim 1 , wherein the cable is attached to at least one connector having at least one of the electrical connector elements configured to make electrical contact with the mating connector, and wherein the at least one electrical device is disposed in the cable outside of a region of the connector.

11. The cable as recited in claim 10 , wherein the at least one electrical device is disposed outside of a connector housing of the connector.

12. The cable as recited in claim 1 , wherein the at least one electrical device is in the form of a passive electrical device.

13. The cable as recited in claim 1 , wherein the at least one electrical device is in the form of an active electrical device.

14. The cable as recited in claim 1 , wherein a plurality of electrical devices are disposed in the cable along the longitudinal cable direction in a spaced-apart relationship to one another.

15. A method for manufacturing a shielded electrical cable according to claim 1 , the method comprising:
a) at least partially removing the insulation of the conductors in a section of the conductors;
b) placing the at least one electrical device on the conductors in the section of the conductors in which the insulation is at least partially removed such that the at least one electrical device is in electrical contact with each of the conductors,
c) surrounding the conductors, the insulation and the at least one electrical device by the cable shield extending along the longitudinal cable direction.

16. The method as recited in claim 15 , wherein the cable shield, together with the at least one electrical device surrounded by the cable shield, is surrounded by a cable jacket extending along the longitudinal cable direction.

17. The method as recited in claim 16 , wherein the cable jacket is made to surround the cable shield using an extrusion process.
