In detail, in the first embodiment, the compartment bracket 3 limits the movement of the mobile heat sink 5 in the up-down direction D2 and the left-right direction D3, so that the mobile heat sink 5 can move between a front position (see FIG. 3 ) located in front of the front end of the upper socket 211 and the lower socket 212, and a rear position (see FIG. 4 ) at least partially extending between the upper socket 211 and the lower socket 212 relative to the compartment bracket 3. Specifically, the compartment bracket 3 limits the movement of the mobile radiator 5 in the up-down direction D2 by the upper wall 31 and the lower wall 32 having the lower window 321, and limits the movement of the mobile radiator 5 in the left-right direction D3 by the two side walls 34, so that the mobile radiator 5 can only move between the front position and the rear position along the front-rear direction D1. In the assembly method described in the first embodiment, the socket connector 2 is first installed on the circuit board, and then the guide shielding cover 1 provided with the partition bracket 3 and the mobile heat sink 5 is covered on the socket connector 2 from top to bottom and fixed to the circuit board, so that when the mobile heat sink 5 is located in the front position in front of the front ends of the upper socket 211 and the lower socket 212, the mobile heat sink 5 can avoid the upper socket 211 of the socket connector 2 to avoid interference with it and affect the assembly. In addition, after the assembly is completed, the mobile heat sink 5 can be moved backward to the rear position extending between the upper socket 211 and the lower socket 212, so that the partition bracket 3 and the mobile heat sink 5 can play a complete spacing role. In general, by enabling the mobile heat sink 5 to move between the front position and the rear position, the partition bracket 3 together with the mobile heat sink 5 can play a complete spacing role in the future, thereby avoiding interference between the mobile heat sink 5 and the socket connector 2 during the assembly process, thereby facilitating the assembly operation. Importantly, by using the built-in heat sink 4 and the mobile heat sink 5 located at the rear position, the distance between the built-in heat sink 4 and the mobile heat sink 5 can be lengthened, and the range of heat dissipation on the pluggable module 200 can be expanded, thereby improving the heat dissipation performance.

The mobile heat sink 5 includes a mobile heat sink 51 and a mobile pressure spring. The mobile pressure spring includes a mobile support frame 52 and a plurality of mobile pressure springs 53. The mobile heat sink 51 is assembled in the mobile support frame 52, and the mobile heat sink 51 includes a base 511 and a plurality of heat sink fins 512. The base 511 has a lower wall 511a and two side assembly plates 511b that extend upward from the left and right side edges of the lower wall 511a in an integral structure. The lower wall 511a of the base 511 has a thermal coupling portion 511c that enters downward into the lower accommodating space 17 through the lower window 321. The front end of the thermal coupling portion 511c has a guide edge 511g. The heat sink fins 512 are interlocked with each other in parallel along the left-right direction D3 and are arranged on the top surface of the base 511. The movable support frame 52 has an upper wall 521 and two side walls 54 extending downward from the upper wall 521. Each of the side assembly plates 511b on both sides of the movable heat sink 51 has a buckle hole 511d. Each of the side walls 54 has a buckle piece 541 extending obliquely inward and backward for buckling with the buckle hole 511d. The width of the buckle hole 511d in the up-down direction D2 is greater than the width of the buckle piece 541, so that the side assembly plates 511b on both sides of the movable heat sink 51 are buckled. b can be assembled on the two side walls 54 of the movable support frame 52 in a floating manner, so that the movable heat sink 51 can move relative to the movable support frame 52 in the vertical direction D2. On the other hand, the movable support frame 52 can limit the movement of the movable heat sink 51 in the left-right direction D3 through the two side walls 54, and the moving distance of the movable heat sink 51 in the vertical direction D2 can be limited through the upper wall 521 and the lower edges of the two side walls 54 bent inward. The movable pressure springs 53 are integrally arranged on the upper wall 521 of the movable support frame 52, and extend obliquely downward to apply elastic force to the heat sink fins 512 of the movable heat sink 51, so that the movable heat sink 51 can move up and down elastically relative to the movable support frame 52 and the compartment bracket 3. When the pluggable module 200 is inserted into the lower accommodating space 17, the movable heat sink 51 can be lifted by the guide edge 511g, so that the pluggable module 200 contacts the thermal coupling portion 511c, and at the same time, the lifted movable heat sink 51 compresses the movable pressure springs 53 to provide elastic force. The movable heat sink 51 can be moved relative to the movable support frame 52 along the vertical direction D2 by the elastic force applied by the movable pressure springs 53, and the thermal coupling portion 511c of the movable heat sink 51 is elastically contacted with the pluggable module 200 to ensure the integrity of the contact and enhance the heat dissipation performance. The two side walls 54 of the movable support frame 52 are constructed as the two side walls 54 of the movable heat sink 5.

The first retaining portion 542 of the mobile heat sink 5 is a limiting hole constructed on the side wall 54 of the mobile heat sink 5, and the second retaining portion 543 of the mobile heat sink 5 is constructed on the front edge of the side wall 54 of the mobile heat sink 5.

In addition, each of the side walls 54 and each of the side assembly plates 511b of the mobile heat sink 5 also has a limiting groove 544, 511e, and each of the side walls 12 of the guide shield 1 also has a limiting piece 127 located behind the corresponding retaining member 126 and extending inwardly and correspondingly entering the limiting groove 544, 511e, and each of the side walls 34 of the compartment bracket 3 has two avoidance openings 341 for the retaining member 126 (the elastic retaining piece) and the limiting piece 127 to pass through. In a modified embodiment, the retaining member 126 (the elastic retaining piece) and the limiting piece 127 can be constructed on the side wall 34 of the compartment bracket 3. The rear end of each of the side walls 54 of the mobile heat sink 5 has a sheet-shaped guide member 545 that extends outward and bends upward. Each of the side walls 34 of the compartment bracket 3 has a guide member receiving notch 342 located at the rear end for accommodating the outward extending portion of the guide member 545. Each of the side walls 12 of the guide shielding cover 1 has a guide rail groove 128. The outward extending portion of the guide member 545 can be slidably disposed in the guide rail groove 128 forward and backward. In addition, the front section of the guide rail groove 128 has a larger opening, so that the upward bent portion of the guide member 545 can pass through accordingly during the assembly process. It should be noted that in other embodiments, the guide member 545 can also be disposed on the two side walls 12 of the guide shield 1, and the guide rail groove 128 can also be disposed on the two side walls 54 of the mobile heat sink 5.

Specifically, referring to Figures 3, 6, and 8 to 9, when the mobile radiator 5 is in the front position, the mobile radiator 5 is roughly accommodated in the rear section of the content storage space 35 of the compartment bracket 3, the elastic retaining sheet (retaining member 126) is snapped into the limiting hole (the first retaining portion 542), the limiting sheet 127 is located at the rear end of the limiting groove 544, 511e, and the guide member 545 is accommodated in the guide member accommodating notch 342 and is located at the front end of the guide rail groove 128; referring to Figures 4, 6, and 10 to 11, when the mobile radiator 5 moves from the front position to In the rear position, the front section of the mobile heat sink 5 is accommodated in the rear section of the content storage space 35 of the compartment bracket 3, and the rear section is disengaged from the content storage space 35 of the compartment bracket 3 to the rear and extends into between the upper socket 211 and the lower socket 212.
