Abstract

A gas arrester is disclosed. In an embodiment a gas arrester for data line systems includes a discharge electrode, a plurality of individual electrodes for connection to data lines and a common gas discharge region formed between the individual electrodes and the discharge electrode.

First claim

The invention claimed is:

1. A gas arrester for data line systems, the gas arrester comprising:
a discharge electrode;
a plurality of individual electrodes for connection to data lines;
a common gas discharge region formed between the individual electrodes and the discharge electrode; and
a ceramic body configured for an electric isolation of the individual electrodes,
wherein the individual electrodes are introduced at least partially into the ceramic body,
wherein the ceramic body comprises a plurality of chambers configured for at least partial inclusion of the individual electrodes, and
wherein a number of the chambers corresponds to a number of individual electrodes.

2. The gas arrester according to claim 1 ,
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 an electric isolation of the discharge electrode and the individual electrodes.

3. The gas arrester according to claim 1 ,
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.

4. The gas arrester according to claim 1 , wherein the chambers fully penetrate through the ceramic body.

5. The gas arrester according to claim 1 , wherein the chambers are filled with a gas.

6. The gas arrester according to claim 5 , wherein the chambers are each separated from one another by a separating wall comprising an incision, which is arranged to enable an exchange of gas between the chambers.

7. The gas arrester according to claim 1 , wherein the ceramic body, the individual electrodes or both the ceramic body and the individual electrodes are of rectangular form.

8. The gas arrester according to claim 1 , wherein the ceramic body, the individual electrodes or both the ceramic body and the individual electrodes are of cylindrical form.

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

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

11. The gas arrester according to claim 1 , wherein the gas arrester is configured for a decay of voltage differences between cores or core pairs of data line systems with more than 2 lines.

12. The gas arrester according to claim 1 , wherein the gas arrester is configured for a protection of Ethernet ports against over-voltage.

13. 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.

14. A gas arrester comprising:
a discharge electrode;
contact elements of the discharge electrode, the contact elements comprising pins or cylinders;
a plurality of individual electrodes for connection to data lines, first sections of the individual electrodes comprising pins or cylinders;
a common gas discharge region formed between the individual electrodes and the discharge electrode;
a ceramic body configured for an electric isolation of the individual electrodes, the individual electrodes being introduced at least partially into the ceramic body;
chambers of the ceramic body; and
separating walls separating the chambers from one another, each of the separating walls comprising an incision allowing an exchange of gas between the chambers.

15. A gas arrester for data line systems, the gas arrester comprising:
a discharge electrode;
a plurality of individual electrodes for connection to data lines;
a common gas discharge region formed between the individual electrodes and the discharge electrode; and
a ceramic body configured for an electric isolation of the individual electrodes,
wherein the individual electrodes are introduced at least partially into 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.

16. The gas arrester according to claim 15 , wherein the ceramic body, the individual electrodes or both the ceramic body and the individual electrodes are of rectangular form or cylindrical form.

17. The gas arrester according to claim 15 , wherein the gas arrester is configured to prevent voltage differences between cores and core pairs in the data line systems with more than 2 lines.

18. The gas arrester according to claim 15 , wherein the gas arrester is configured for a decay of voltage differences between cores or core pairs of data line systems with more than 2 lines.

19. The gas arrester according to claim 15 , wherein the gas arrester is configured for a protection of Ethernet ports against over-voltage.

20. The gas arrester according to claim 15 , 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.
