Abstract

An apparatus including: a base plate; a guide rail being disposed on the base plate; a sliding bar with a first side being disposed on the guide rail, wherein the sliding rail includes a wedge on a second side of the sliding bar opposite the first side; and a heat sink, wherein the base plate and the heat sink form a slot for insertion of a pluggable module at a front of the slot.

Claims (29)

1. An apparatus comprising;

a base plate;

a guide rail being disposed on the base plate;

a sliding bar with a first side being disposed on the guide rail, wherein the sliding bar includes a wedge on a second side of the sliding bar opposite the first side; and

a heat sink rotatably connected to the base plate,

wherein the base plate and the heat sink form a slot for insertion of a pluggable module at a front of the slot;

further comprising at least one hinge coupled to the base plate and to the heat sink; and

wherein the sliding bar comprises an aperture with an internal thread for a thumb screw, wherein screwing the thumb screw into the internal thread of the aperture causes the sliding bar to be pulled towards the front of the slot.

2. An apparatus comprising:

a base plate;

a guide rail being disposed on the base plate;

a sliding bar with a first side being disposed on the guide rail, wherein the sliding bar includes a wedge on a second side of the sliding bar opposite the first side; and

a heat sink,

wherein the base plate and the heat sink form a slot for insertion of a pluggable module at a front of the slot,

wherein the sliding bar comprises an aperture with an internal thread for a thumb screw, wherein screwing the thumb screw the internal thread of the aperture causes the sliding bar to be pulled towards the front of the slot.

3. The apparatus according to claim 2 , further comprising a first spring, wherein the sliding bar and the guide rail are configured to be connected via the first spring, the first spring being positioned substantially parallel to an axis along the length of the sliding bar and between a protuberance of the sliding bar and a cavity of the guide rail, and pulling the sliding bar toward the front of the slot causes the first spring to be compressed.

4. The apparatus according to claim 2 , wherein opening the thumb screw by screwing the thumb screw out of the aperture, causes the sliding bar to be pushed away from the front of the slot.

5. The apparatus according to claim 3 , wherein opening the thumb screw by screwing the thumb screw out of the aperture, allows the first spring to extend, wherein extension of the first spring causes the sliding bar to be pushed away from the front of the slot.

6. The apparatus according to claim 3 , further comprising:

a second spring connecting the guide rail and the heat sink,

wherein the second spring being positioned substantially perpendicular to the first spring and between a spring seat of the guide rail and a retention cage of the heat sink, and pulling the sliding bar towards the front of the slot causes the wedge to be moved to a position not being below the retention cage thereby allowing the second spring to be extended, wherein extending the second spring causes the heat sink to be pushed downward causing the heat sink to come into contact with an upper surface of the pluggable module.

7. The apparatus according to claim 6 , wherein pushing the sliding bar away from the front of the slot causes the wedge to be moved to a position below the retention cage thereby causing the heat sink to be moved away from the base plate thereby opening the slot and enabling extraction of the pluggable module out of the slot.

8. The apparatus according to claim 3 , further comprising:

a second spring connecting the guide rail and the heat sink,

wherein the second spring being positioned substantially perpendicular to the first spring and between the guide rail and a lower surface of a ramp-shaped protuberance of the heat sink, and pulling the sliding bar towards the front of the slot causes the wedge of the sliding bar to be pulled over a surface of the ramp-shaped protuberance of the heat sink thereby pulling the heat sink towards the base plate and causing the heat sink come into contact with an upper surface of the pluggable module.

9. The apparatus according to claim 8 , wherein pulling the heat sink towards the base plate causes the second spring to be compressed.

10. The apparatus according to claim 9 , wherein opening the thumb screw by screwing the thumb screw out of the aperture allows the first spring to extend, extension of the first spring causes the sliding bar to be pushed away from the front of the slot, pushing the sliding bar away from the front causes the wedge of the sliding bar to be pushed away from the lateral surface of the ramp-shaped protuberance of the heat sink thereby allowing the second spring to extend thereby causing the heat sink to move away from the base plate thereby opening the slot enabling extraction of the pluggable module out of the slot.

11. The apparatus of claim 1 , wherein the guide rail is disposed on the base plate at a first lateral side thereof, and the at least one hinge is disposed on the base plate at a second lateral side thereof.

12. The apparatus of claim 1 , further comprising a first spring, wherein the sliding bar and the guide rail are configured to be connected via the first spring, the first spring being positioned substantially parallel to an axis along the length of the sliding bar and between a protuberance of the sliding bar and a cavity of the guide rail, and pulling the sliding bar toward the front of the slot causes the first spring to be compressed.
