Abstract

A connector that includes a contact, a connection piece, and a cooling unit. The connection piece is received by the contact, and the cooling unit is connected to the connection piece. The cooling unit includes a heat sink spaced from the contact, a first heat exchanger section between the contact and the connection piece, a second heat exchanger section positioned in the heat sink and in communication with the first heat exchanger section, and a heat transfer medium that circulates between the first heat exchanger section and the second heat exchanger section.

First claim

What is claimed is:

1. A connector comprising,
a contact;
a connection piece received by the contact; and
a cooling unit connected to the connection piece and having:
(a) a heat sink spaced from the contact,
(b) a first heat exchanger section between the contact and the connection piece, and
(c) a second heat exchanger section in and connected to the heat sink and in communication with the first heat exchanger section, and
(d) a heat transfer medium circulating between the first heat exchanger section and the second heat exchanger section.

2. The connector according to claim 1 , wherein the heat transfer medium has dielectric properties.

3. The connector according to claim 2 , wherein the heat transfer medium includes water and an additive selected from a group consisting of a perfluorinated carbon, a hydrocarbon chain, a long-chain hydrocarbon, a synthetic oil, a transformer oil, a polyalphaolefin, and an ester oil.

4. The connector according to claim 1 , wherein the contact includes a contact surface on an outer peripheral surface thereof.

5. The connector according to claim 4 , wherein the contact further has a tube receiving passageway extending there through and receiving the connection piece.

6. The connector according to claim 5 , wherein the contact further has a first joining section on a longitudinal end thereof.

7. The connector according to claim 6 , wherein the connection piece includes a tubular section received by the tube receiving passageway.

8. The connector according to claim 7 , wherein the connection piece further has a second joining section extending from the tubular section connecting to the first joining section.

9. The connector according to claim 8 , wherein the first joining section has an internal thread and the second joining section has an external thread corresponding to the internal thread.

10. The connector according to claim 9 , wherein the connection piece has an inlet at one end thereof.

11. The connector according to claim 10 , wherein the connection piece further has a tip at an opposite end thereof.

12. The connector according to claim 11 , wherein the connection piece further has a first channel section extending through an inside of the tubular section and in communication with the tip and the inlet.

13. The connector according to claim 12 , wherein the tube receiving passageway has a base offset from the tip.

14. The connector according to claim 13 , wherein the connection piece further has a second channel section adjacent to the inlet and offset from and running parallel to the first channel section.

15. The connector according to claim 14 , wherein the connection piece further has a third channel section connecting the first channel section to the second channel section.

16. The connector according to claim 15 , wherein the third channel section is inclined relative to the first channel section and the second channel section.

17. The connector according to claim 16 , wherein the connection piece further has an outlet adjacent to the inlet.

18. The connector according to claim 17 , wherein the tubular section has an outer peripheral surface spaced from the tube receiving passageway and delimiting the first heat exchanger section.

19. The connector according to claim 18 , wherein the first heat exchanger section is connected to the outlet.

20. The connector according to claim 19 , wherein the connection piece further has a fourth channel section overlapping the first channel section and an opening into the tube receiving passageway.

21. The connector according to claim 20 , wherein the fourth channel section is ring-shaped and on a periphery of the tubular section.

22. The connector according to claim 21 , wherein the connection piece further has a fifth channel section connecting the outlet with the fourth channel section.

23. The connector according to claim 22 , wherein the cooling unit further includes:
(a) a first connection tube connecting the heat sink to the inlet, and
(b) a second connection tube connecting the outlet to the heat sink.
