Abstract

A gas arrester is disclosed. In an embodiment a gas arrester for a data line system includes a discharge electrode, a plurality of individual electrodes configured to connect data lines and a common gas discharge region formed between the individual electrodes and the discharge electrode, wherein the gas arrester is configured to reduce voltage differences between lines or line pairs of the data line system with more than 2 lines.

First claim

What is claimed is:

1. A gas arrester for a data line system, the gas arrester comprising:
a discharge electrode;
a plurality of individual electrodes configured to connect data lines, wherein each individual electrode is assigned to a respective one of the data lines, and wherein a number of the individual electrodes is equal to a number of the data lines; and
a common gas discharge region formed between the individual electrodes and the discharge electrode,
wherein the gas arrester is configured to reduce voltage differences between lines or line pairs of the data line system with more than 2 lines.

2. The gas arrester according to claim 1 , further comprising a ceramic body configured to electrically isolate the individual electrodes, wherein the individual electrodes are introduced at least partially into the ceramic body.

3. The gas arrester according to claim 2 ,
wherein the discharge electrode is bonded in a gas-tight manner to the ceramic body, and
wherein the ceramic body is arranged at least partially between the discharge electrode and the individual electrodes for electric isolation of the discharge electrode and the individual electrodes.

4. The gas arrester according to claim 2 , wherein the ceramic body comprises a metallization, and wherein the individual electrodes are bonded to the ceramic body through the metallization in a gas-tight manner.

5. The gas arrester according to claim 2 ,
wherein the ceramic body comprises a plurality of chambers configured to at least partial include the individual electrodes, and
wherein a number of the chambers corresponds to a number of individual electrodes.

6. The gas arrester according to claim 5 , wherein the chambers fully penetrate through the ceramic body.

7. The gas arrester according to claim 5 , wherein the chambers are filled with a gas.

8. The gas arrester according to claim 7 , wherein the chambers are each separated from one another by a separating wall comprising an incision configured to enable an exchange of gas between the chambers.

9. The gas arrester according to claim 2 , wherein the ceramic body, the individual electrodes or both the ceramic body and the individual electrodes are of rectangular form.

10. The gas arrester according to claim 2 , wherein the ceramic body, the individual electrodes or both the ceramic body and the individual electrodes are of cylindrical form.

11. The gas arrester according to claim 1 , wherein the gas arrester comprises at least four individual electrodes.

12. The gas arrester according to claim 1 , wherein the gas arrester is configured to prevent voltage differences between the lines and the line pairs in the data line system with more than 2 lines.

13. The gas arrester according to claim 1 , wherein the gas arrester is configured to protect Ethernet ports against over-voltage.

14. The gas arrester according to claim 1 , further comprising:
contact elements of the discharge electrode, the contact elements comprising pins or cylinders; and
first sections of the individual electrodes, the first sections comprising pins or cylinders.

15. A method for operating a gas arrester in data line system, wherein the gas arrester includes a discharge electrode, a plurality of individual electrodes for connecting data lines and a common gas discharge region formed between the individual electrodes and the discharge electrode, wherein each individual electrode is assigned to a respective one of the data lines, and wherein a number of the individual electrodes is equal to a number of the data lines, the method comprising:
reducing voltage differences between lines or line pairs of the data line system with more than 2 lines.

16. A gas arrester for data line systems, the gas arrester comprising:
a discharge electrode;
a plurality of individual electrodes configured to connect to data lines;
a common gas discharge region located between the individual electrodes and the discharge electrode; and
a ceramic body configured to electrically isolate the individual electrodes,
wherein the individual electrodes are arranged at least partially in the ceramic body,
wherein the discharge electrode is bonded in a gas-tight manner to the ceramic body, and
wherein the ceramic body is arranged at least partially between the discharge electrode and the individual electrodes for electric isolation of the discharge electrode and the individual electrodes.

17. A gas arrester for data line systems, the gas arrester comprising:
a discharge electrode;
a plurality of individual electrodes configured to connect to data lines;
a common gas discharge region located between the individual electrodes and the discharge electrode; and
a ceramic body configured to electrically isolate the individual electrodes,
wherein the individual electrodes are arranged at least partially in the ceramic body,
wherein the ceramic body comprises a metallization, and
wherein the individual electrodes are bonded to the ceramic body through the metallization in a gas-tight manner.

18. A gas arrester for data line systems, the gas arrester comprising:
a discharge electrode;
a plurality of individual electrodes configured to connect to data lines, wherein each individual electrode is assigned to a respective one of the data lines, and wherein a number of the individual electrodes is equal to a number of the data lines; and
a common gas discharge region located between the individual electrodes and the discharge electrode,
wherein the gas arrester is configured to prevent voltage differences between the lines and line pairs in the data line system with more than 2 lines.
