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.

First claim

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 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.

2 . The apparatus according to claim 1 , 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 . An apparatus comprising:
a base plate; a rod; and a heat sink, wherein the heat sink is disposed on the rod, and wherein the heat sink and the base plate form a slot for mounting a pluggable module into the slot.

12 . The apparatus according to claim 11 , wherein turning the rod around its longitudinal axis causes the heat sink to be moved away from the base plate thereby opening the slot enabling insertion and/or extraction of the pluggable module at a front of the slot.

13 . The apparatus according to claim 12 , wherein the rod comprising a section including a cam, the cam varying the radius of the rod around the rods diameter, wherein at the section including the cam being disposed on a spring seat of the base plate, and a spring being disposed between the spring seat of the base plate and a retention cage of the heat sink.

14 . The apparatus according to claim 13 , wherein the rod comprises a knob and turning the rod around its longitudinal axis until the knob points to a first direction causes the cam to be in a first direction have an increased radius of the rod where the rod is disposed on the spring seat of the base plate thereby causing the spring to be compressed while moving the heat sink away from the base plate thereby opening the slot enabling insertion and/or extraction of the pluggable module at the front of the slot.

15 . The apparatus according to claim 13 , wherein the rod comprises a knob and turning the rod around its longitudinal axis until the knob points to a second direction causes the cam to be at lower radius of the rod where the rod is disposed on the spring seat of the base plate allowing the spring to extend thereby pulling the heat sink towards the base plate thereby causing the heat sink to come into contact with an upper surface of the pluggable module being inserted into the slot.
