Referring to Figures 3 to 6, each spring support structure 37 has two first support portions 371 and two second support portions 372 extending laterally along the left-right direction D3. The second support parts 372 are staggered from each other in the front-rear direction D1 and the up-down direction D2. In other words, the two second support parts 372 are respectively located in front of the two first support parts 371 and are positioned higher than the two first support parts 371. Two first support parts 371. Specifically, the first supporting portion 371 is configured as a supporting recess that is concave downward and extends laterally along the left-right direction D3, and the second supporting portion 372 is configured as protruding upward and is located at the corresponding third supporting portion. A support convex portion extends laterally along the left-right direction D3 in front of the support portion 371 .

Referring to Figures 1, 2, 5 and 6, the buckle 4 is immovably assembled to the guide shield 1. The buckle 4 extends laterally along the left-right direction D3 and exerts an elastic force downward. The two spring portions 41 of the two spring support structures 37 of the radiator 3 and the two buckles connected to the left and right sides of the two spring portions 41 and respectively buckled to the two side walls 113 of the guide shield 1 Connector 42. Each buckle portion 42 has two buckle holes 421 buckled with the two buckle blocks 113a of the corresponding side wall 113 . The elasticity of the two spring portions 41 enables the radiator 3 to move in the up-down direction D2 relative to the guide shield 1 .

Each spring portion 41 has two connecting arms 411 that extend laterally and obliquely upward along the left-right direction D3 and are respectively connected to the two buckling portions 42, and an escape groove 412 extending along the left-right direction D3. and a blocking flange 413 located at the front edge and extending upward for the heat dissipation fins 35 of the heat sink 3 to abut rearward to limit the heat sink 3 in the rearward direction. The buckle 4 can limit the radiator 3 in the rearward direction through the blocking flange 413 located at the front edge of the spring portion 41. For example, the rear edge of the spring portion 41 can also be used to provide The heat dissipation fins 35 of the heat sink 3 abut forward to limit the heat sink 3 in the forward direction, and the rear edge of the spring portion 41 can also be provided with a structure similar to the blocking flange 413 . In other words, the buckle 4 may have the function of assisting in limiting the position of the radiator 3 in the front-rear direction D1.

Referring to Figures 1, 5, 7 and 8, when the pluggable module 200 has not yet been inserted into the insertion channel 115 of the guide shield 1, the pushed portion 33 of the heat sink 3 has not yet been pushed. The radiator 3 is located in an initial position below and in front. The first support part 371 cooperates with the spring part 41 of the buckle 4 and interacts with the spring part 41 of the buckle 4. The two support parts 372 and the spring part 41 of the buckle 4 are staggered in the front-rear direction D1 , and the two spring parts 41 of the buckle 4 exert a downward and elastic preload force on the radiator 3 . In this state, one of the second support portions 372 located at the rear is accommodated in the escape groove 412 without interacting with the spring portion 41 of the buckle 4 , and the other second support portion 372 located at the front is The portion 372 is located in front of the spring portion 41 and is offset from the spring portion 41 .

Referring to FIG. 9 , when the pluggable module 200 is inserted into the insertion channel 115 of the guide shield 1 and pushes the pushed portion 33 of the heat sink 3 in the first insertion stage, the pluggable module 200 passes through the heat sink 3 The cooperation of the guide slope 321 of the thermal coupling part 32 with the pluggable module 200 causes the pluggable module 200 to lift the radiator 3 upward to a transition position above and in front. The heat sink 3 moves upward but does not move backward, and the upper surface of the pluggable module 200 contacts the thermal coupling portion 32 of the heat sink 3 . At this time, the first support part 371 cooperates with the spring part 41 of the buckle 4, and lifts the spring part 41 of the buckle 4 upward to cause the two spring parts 41 of the buckle 4 to generate Elastically deforming, the two spring portions 41 of the buckle 4 exert a downward and elastic transition load force on the radiator 3 . In this first insertion stage, because the heat sink 3 only moves upward and not backward, one of the second supporting parts 372 is still accommodated in the avoidance groove 412 , and the other second supporting part 372 is still located there. The spring portion 41 is offset from the spring portion 41 forward. Wherein, the transition load force is greater than the preload force.

In other words, when the pluggable module 200 has not been inserted into the plug-in channel 115 of the guide shield 1 , and when the plug-in module 200 is inserted into the plug-in channel 115 of the guide shield 1 , In an insertion stage, the pushed parts 33 are not pushed yet, the first supporting part 371 of the heat sink 3 interacts with the spring part 41 of the buckle 4, and at this time the heat sink 3 It can move relative to the guide shield 1 between the initial position below and in front and the transition position above and in front.

Referring to FIG. 10 and FIG. 11 , when the pluggable module 200 is inserted into the insertion channel 115 of the guide shield 1 and pushes the pushed portion 33 of the heat sink 3 backward in the second insertion stage, the The radiator 3 moves backward relative to the guide shield 1 to a working position above and behind, and the return spring action portion 34 of the radiator 3 acts backward on the return spring 114a to compress the return spring 114a. At this time, the first support part 371 of the heat sink 3 leaves the spring part 41 of the buckle 4 , and the second support part 372 of the heat sink 3 moves to match the spring part of the buckle 4 The position of the portion 41 and interacts with the spring portion 41 of the buckle 4. In this state, the second support portion 372 moves backward to below the bottom surface of the spring portion 41 of the buckle 4 and Further lifting the spring portion 41 and further elastically deforming the spring portion 41 (increasing the amount of elastic deformation), the two spring portions 41 of the buckle 4 exert a downward and elastic force on the radiator 3 The working load force is used to provide the working contact pressure between the heat sink 3 and the surface of the pluggable module 200 . Wherein, the working load force is greater than the transition load force and is greater than the preload force.

When the pluggable module 200 begins to withdraw from the plug channel 115 but before losing contact with the thermal coupling portion 32 of the heat sink 3 , the returning elastic force of the return spring 114 a pushes the return spring action portion 34 forward. , the radiator 3 moves forward from the working position to the transition position, the second support part 372 leaves the spring part 41 , and the first support part 371 moves to a position that matches the spring part 41 , the elastic deformation of the spring part 41 is reduced (the amount of elastic deformation is reduced), and the force exerted downwardly on the radiator 3 by the two spring parts 41 of the buckle 4 is reduced from the working load force to the transition force. load force. When the pluggable module 200 is completely withdrawn from the plug channel 115 and loses contact with the thermal coupling portion 32 of the heat sink 3, the heat sink 3 moves from the transition position toward the transition position due to the force of the spring portion 41. Moving downward to the initial position, the elastic deformation of the spring portion 41 is further reduced, and the downward force exerted by the two spring portions 41 of the buckle 4 on the radiator 3 is reduced from the transition load force to the desired Describe the preload force.

In the first insertion stage, the pluggable module 200 moves a relatively long distance relative to the thermal coupling portion 32 of the heat sink 3 in contact. At this time, the two spring portions 41 of the buckle 4 move toward The transition load force exerted on the heat sink 3 is relatively small, which reduces the contact pressure between the heat sink 3 and the surface of the pluggable module 200 at this stage, so as to reduce the pluggable module 200. The friction resistance during the insertion process of the draft set 200 is reduced, and the possibility of wear of the thermal coupling portion 32 of the heat sink 3 and its thermal interface material is reduced.

In the second insertion stage, the pluggable module 200 has completely contacted the thermal coupling part 32 of the heat sink 3, and the pluggable module 200 starts to push the pushed part of the heat sink 3. In this stage of 33, the thermal coupling part 32 of the heat sink 3 is in contact with the upper surface of the pluggable module 200 and moves together with the pluggable module 200 to finally complete the insertion. In this process, the heat dissipation There is no relative movement between the device 3 and the pluggable module 200, so there is no friction force generated by relative movement between the two. In this way, when the transition load force exerted by the two spring portions 41 of the buckle 4 increases to the working load force, the thermal coupling portion 32 of the radiator 3 and the thermal interface material of the heat sink 3 can be prevented from wearing and tearing. damaged. Furthermore, when designing the working load force that the buckle 4 can exert, there is less need to worry about the wear of the thermal coupling portion 32 of the radiator 3 and its thermal interface material, so the buckle The working load force that the tool 4 can exert can be designed to be larger to improve the heat conduction efficiency and increase the heat dissipation effect. In addition, since the moving distance in the second insertion stage is relatively short, the transition load force exerted by the two spring portions 41 of the buckle 4 can be increased to the working load within a relatively short moving distance. force.

In summary, the present invention can provide a smaller transition in the first insertion stage of the plugging process through the two-stage movement of the heat sink 3 and the two-stage change of applied force of the buckle 4 The load force reduces the contact pressure between the heat sink 3 and the surface of the pluggable module 200 at this stage to reduce the frictional resistance during the insertion process, and after completing the plug-in (the third step of the plug-in process) After the second insertion stage), a larger workload force is provided to improve the heat conduction efficiency and increase the heat dissipation effect. Furthermore, in a structure in which the heat sink 3 includes a thermal interface material, the possibility of damage to the thermal interface material can be reduced.

However, the above are only examples of the present invention, and should not be used to limit the scope of the present invention. All simple equivalent changes and modifications made based on the patent scope of the present invention and the content of the patent specification are still within the scope of the present invention.
