Abstract

In order to improve the transmission characteristics and to prevent distortions, a signal cable with two juxtaposed insulated conductors with connecting elements is proposed, in which each conductor is surrounded by its own coaxial individual screen and the screens are insulated against the connecting elements. The conductors and the individual screens are jointly surrounded by an insulated overall screen, which is electrically connected to at least one of the connecting elements.

Claims

1. A signal cable, such as an amplifier cable, comprising two juxtaposed insulated conductors with associated connecting elements, wherein each conductor is individually surrounded by a coaxial screen which is electrically insulated from its associated conductor, and each screen being electrically insulated with respect to one another and from the connecting elements.

2. A signal cable according to claim 1, wherein the conductors and the individual screens are jointly surrounded by an insulated overall screen.

3. A signal cable according to claim 2, wherein the overall screen is electrically connected to at least one of the connecting elements.

4. A signal cable according to claim 2, wherein the overall screen is electrically connected to both connecting elements.

5. A signal cable according to one of the preceding claims, wherein the individual screens are constructed as bare or tin-coated copper meshes.

6. A signal cable according to claim 2, wherein the overall screen is constructed as a silver-coated copper mesh.

7. A signal cable according to claim 1, wherein the conductors are silver-coated.

8. A signal cable according to claim 1, whrein the conductors comprise individual insulated stranded wires.

9. A signal cable according to claim 8, wherein the individual insulation of the stranded wires comprises a fluorocarbon material.
