Abstract

A two-wire line includes a first conductor. A first dielectric thread is wrapped around the first conductor. The two-wire line includes a second conductor. A second dielectric thread is wrapped around the second conductor. The first conductor and the second conductor are at a distance from one another. The distance is smaller than the sum of the thickness of the first thread and the thickness of the second thread.

First claim

The invention claimed is:

1. Two-wire line having a first conductor, around which a first dielectric thread is wrapped, and a second conductor, around which a second dielectric thread is wrapped, wherein the first conductor and the second conductor are at a distance from one another, which distance is smaller than a sum of a thickness of the first thread and a thickness of the second thread, wherein the first thread is unwound on the first conductor in the form of a first helix and the second thread is unwound on the second conductor in the form of a second helix, and wherein the first helix and the second helix are opposed.

2. Two-wire line according to claim 1 , wherein the first thread and the second thread are spaced at a distance.

3. Two-wire line according to claim 1 , wherein the first thread covers less than 50% of the first conductor, and wherein the second thread covers less than 50% of the second conductor.

4. Two-wire line according to claim 1 , wherein the first thread touches the second conductor, and wherein the second thread touches the first conductor.

5. Two-wire line according to claim 1 , wherein the two-wire line also has an electrical shield, wherein the electrical shield encloses at least one area in which the first conductor, the second conductor, the first thread and the second thread are located.

6. Two-wire line according to claim 5 , wherein the two-wire line also has an insulating film, which is located between the shield and the first conductor, the second conductor, the first thread and the second thread.

7. Method for producing a two-wire line, the method comprising:
unwinding of a first conductor by a first spool and a second conductor by a second spool;
provision of the first conductor with a first dielectric thread and the second conductor with a second dielectric thread;
assembly of the first conductor provided with the first dielectric thread and the second conductor provided with the second dielectric thread, wherein the first conductor and the second conductor are at a distance from one another, which distance is smaller than a sum of a thickness of the first thread and a thickness of the second thread, wherein the first thread is unwound on the first conductor in the form of a first helix and the second thread is unwound on the second conductor in the form of a second helix, and wherein the first helix and the second helix are opposed.

8. Device for producing a two-wire line, wherein the device has:
a first unwinding unit, which is designed to unwind a first conductor;
a second unwinding unit, which is designed to unwind a second conductor;
a first wrapping unit, which is designed to provide the first conductor with a first dielectric thread;
a second wrapping unit, which is designed to provide the second conductor with a second dielectric thread;
a redirection unit, which is designed to assemble the first conductor provided with the first dielectric thread and the second conductor provided with the second dielectric thread, wherein the first conductor and the second conductor are at a distance from one another, which distance is smaller than a sum of a thickness of the first thread and a thickness of the second thread, wherein the first thread is unwound on the first conductor in the form of a first helix and the second thread is unwound on the second conductor in the form of a second helix, and wherein the first helix and the second helix are opposed.
