Abstract

A connector is provided and includes a cage, a plurality of partition devices, and a heat dissipation device. The cage includes a plurality of plug receiving units that are arranged in at least a two columns by two rows arrangement. The plurality of partition devices include an upper partition plate and a lower partition plate and is positioned between two adjacent plug receiving units of the plurality of plug receiving units. The heat dissipation device includes a heat conduction block positioned between the upper partition plate and the lower partition plate, and a heat conduction pipe that contacts the heat conduction block and extends beyond a rear wall of the cage.

First claim

What is claimed is:

1. A connector, comprising:
a cage having a plurality of plug receiving units arranged in at least a two column by two row arrangement;
a plurality of partition devices having an upper partition plate and a lower partition plate and positioned between two adjacent plug receiving units of the plurality of plug receiving units; and
a heat dissipation device having:
a heat conduction block positioned between the upper partition plate and the lower partition plate; and
a heat conduction pipe contacting the heat conduction block and extending beyond a rear wall of the cage.

2. The connector according to claim 1 , wherein the cage includes an upper cage and a lower cage detachably assembled with the upper cage.

3. The connector according to claim 1 , wherein the heat dissipation device includes a radiator rearward mounted on the outside of the cage and connected to the heat conduction pipe.

4. The connector according to claim 3 , wherein the upper partition plate and the lower partition plate include an opening.

5. The connector according to claim 4 , wherein upper and lower surfaces of the heat conduction block include a protrusion that passes through the opening and extends outside the upper partition plate and the lower partition plate.

6. The connector according to claim 3 , wherein the radiator includes:
a base; and
a plurality of fins disposed on opposite surfaces of the base and arranged parallel to each other.

7. The connector according to claim 6 , wherein the heat conduction pipe is substantially L-shaped and includes a first arm inserted into the cage and contacts the heat conduction block.

8. The connector according to claim 7 , wherein the heat conduction pipe further includes a second arm integrally connected to the first arm and mounted between adjacent fins of the plurality of fins.

9. The connector according to claim 8 , further comprising a rear cover plate secured to the rear of the cage and having a heat conduction receiving through hole.

10. The connector according to claim 9 , further comprising a fourth elastic member extending away from the rear cover plate and snap fit with a protrusion platform disposed on one of the plurality of fins.

11. The connector according to claim 10 , wherein the protrusion platform is positioned on an uppermost fin of the plurality of fins.

12. The connector according to claim 1 , wherein the heat conduction pipe contacts a side surface of the heat conduction block.

13. The connector according to claim 12 , wherein the heat dissipation device further includes a first elastic member securing the heat conduction block in contact with the heat conduction pipe.

14. The connector according to claim 13 , further comprising a connection plate positioned along a first side of the upper partition plate and the lower partition plate.

15. The connector according to claim 14 , wherein the first elastic member is a spring protruding inward from the connection plate.

16. The connector according to claim 15 , wherein the first elastic member is an elastic thermal pad positioned between the heat conduction block and the heat conduction pipe.

17. The connector according to claim 15 , wherein the spring urges the heat conduction block to maintain contact with the heat conduction pipe.

18. The connector according to claim 17 , further comprising a second elastic member positioned along a second side that is opposite to the first side along one of the upper partition plate and the lower partition plate.

19. The connector according to claim 18 , wherein the second elastic member urges the heat conduction pipe upward.

20. The connector according to claim 19 , further comprising a third elastic member positioned on one of the upper partition plate and the lower partition plate and urging the heat conduction block upward.

21. The connector according to claim 19 , further comprising a guide device disposed along an inner side of a side wall of a receiving unit of the plurality of plug receiving units that is adjacent the second side.

22. The connector according to claim 21 , wherein a plurality of fourth elastic members is disposed along a top wall of the upper cage and a bottom wall of the lower cage.

23. The connector according to claim 21 , wherein the guide device includes an upper protrusion protruding inward from the inner side of the side wall.

24. The connector according to claim 23 , wherein the guide device further includes a lower protrusion protruding inward from the inner side of the side wall.

25. The connector according to claim 24 , wherein a vertical distance between the upper protrusion and the lower protrusion is substantially equal to a height of the heat conduction pipe.
