Gas tube impulse protection
View Patent ↗Methods, systems, and apparatus for protecting electrical components are disclosed. In one aspect a system includes a first gas discharge tube connected to a first conductor of a first twisted wire pair; and a second gas discharge tube connected to a second conductor of the first twisted wire pair. The first gas discharge tube can also be connected to a third conductor of a second twisted wire pair, and the second gas discharge tube can be connected to a fourth conductor of the second twisted wire pair.
1. A protection circuit, comprising:
a first gas discharge tube having a first terminal connected to a first conductor of a first twisted wire pair; and
a second gas discharge tube having a first terminal connected to a second conductor of the first twisted wire pair, wherein the first conductor is a tip conductor of the first twisted wire pair and the second conductor is a ring conductor of the first twisted wire pair, and each of the first gas discharge tube and the second gas discharge tube also have other terminals connected to a second different twisted wire pair.
2. The protection circuit of claim 1 , wherein:
a second terminal of the first gas discharge tube is connected to a third conductor of a second twisted wire pair; and
a second terminal of the second gas discharge tube is connected to a fourth conductor of the second twisted wire pair.
3. The protection circuit of claim 2 , wherein the first conductor is a positive conductor of the first twisted wire pair, and the third conductor is a positive conductor of the second twisted wire pair.
4. The protection circuit of claim 2 , wherein the second conductor is a negative conductor of the first twisted wire pair, and the fourth conductor is a negative conductor of the second twisted wire pair.
5. The protection circuit of claim 2 , wherein the first conductor is connected to pin 3 of an RJ45 connector and the second conductor is connected to pin 1 of the RJ45 connector.
6. The protection circuit of claim 5 , wherein the third conductor is connected to pin 2 of the RJ45 connector and the fourth conductor is connected to pin 6 of the RJ45 connector.
7. A method, comprising:
connecting a first terminal of a first gas discharge tube to a first conductor of a first twisted wire pair; and
connecting a second terminal of the first gas discharge tube to a first conductor of a second different twisted wire pair, wherein:
connecting a first terminal comprises connecting the first terminal of the first gas discharge tube to a tip conductor of the first twisted wire pair; and
connecting a second terminal comprises connecting the second terminal of the first gas discharge tube to a ring conductor of the second twisted wire pair.
8. The method of claim 7 , further comprising connecting a first terminal of a second gas discharge tube to a second conductor of the first twisted wire pair.
9. The method of claim 8 , further comprising connecting a second terminal of the second gas discharge tube to a second conductor of the second twisted wire pair.
10. The method of claim 7 , wherein the first twisted wire pair and the second twisted wire pair are Ethernet wire pairs.
11. The method of claim 7 , wherein the first twisted wire pair is connected to pin 1 and pin 2 of an RJ45 connector and the second twisted wire pair is connected to pin 3 and pin 6 of the RJ45 connector.
12. The method of claim 7 , wherein connecting the first terminal comprises connecting the first terminal to a tip conductor of the first twisted wire pair.
13. The method of claim 12 , wherein connecting the second terminal comprises connecting the second terminal to a tip conductor of the second twisted wire pair.
