Description

Technical Field

[0001] The present invention relates to a connector assembly, and more particularly to a connector assembly having a heat sink module. Background Art

[0002] Chinese Patent Publication No. CN110296628A (corresponding to US Patent Publication No. US10,651,598B2) discloses a heat exchange structure, which includes a metal part, a lever, and a frame. The frame is used to support the lever and the metal part, and the front end of the metal part is fixed to the front edge of the frame by a fastener such as a rivet. When a heat source slides relative to the heat sink, the heat source contacts one end of the lever and actuates the other end of the lever to contact the rear end of the metal part. The metal part pushes the heat sink downward, and a heat conducting pad provided on the heat sink contacts the heat source of the heat sink. However, in this prior art, an additional frame is required to install the lever and the metal part. Moreover, the metal part needs to be provided on the top of the heat sink, resulting in the need to groove the top of the heat sink to install the metal part, thus reducing the heat dissipation area of the heat sink. In addition, the metal part is only combined with the heat sink at a single point (screw), and when the lever is pushed, it presses on the rear end of the metal part, and this design makes the heat sink prone to skew. Summary of the Invention

[0003] Therefore, an object of the present invention is to provide a connector assembly that can improve at least one drawback in the prior art.

[0004] Thus, in some embodiments, the connector assembly of the present invention includes a guiding shield and a radiator module. The guiding shield has at least one plugging space inside. The radiator module includes a heat sink, a pressing elastic element, a lever element, and a supporting elastic element. The bottom of the heat sink has a thermal coupling portion. The pressing elastic element is disposed at the side of the heat sink. The lever element has a pushed end to be pushed and a pressing end to press downward on the pressing elastic element. The supporting elastic element supports the heat sink upward and elastically. The heat sink can move between a higher release position and a lower working position where the thermal coupling portion extends into the plugging space relative to the plugging space. When the pushed end of the lever element is pushed by an external force and the lever element rotates, the pressing end of the lever element presses downward on the pressing elastic element, causing the pressing elastic element to push the heat sink downward to the working position and causing the heat sink to compress the supporting elastic element downward. The compressed supporting elastic element can provide a restoring force to return the heat sink to the release position when the external force is removed. When the pushed end of the lever element is not pushed by an external force, the supporting elastic element supports the heat sink upward to make the heat sink located at the release position, and the heat sink acts on the lever element through the pressing elastic element to make the pushed end of the lever element extend into the plugging space.

[0005] In some embodiments, an upper radiator module and a lower radiator module each including the heat sink, the pressing elastic element, the lever element, and the supporting elastic element are included. The guiding shield includes a shield body, an upper radiator bracket, and a lower radiator bracket disposed on the shield body. The lower radiator bracket and the shield body in the shield body jointly define an upper plugging space and a lower plugging space. The lower radiator module is installed on the lower radiator bracket and corresponds to the lower plugging space. The upper radiator module is installed on the upper radiator bracket and corresponds to the upper plugging space.

[0006] In some embodiments, two of the pressing elastic elements are respectively disposed at two sides of the heat sink, and two of the supporting elastic elements are respectively disposed at two sides of the heat sink.

[0007] In some embodiments, each pressing elastic element has a heat sink acting portion located at the front and rear ends for pushing the heat sink, and a lever acting portion located in the middle for being pressed by the pressing end of the lever element. Each supporting elastic element has two elastic supporting portions arranged front and rear for supporting the heat sink upward.

[0008] In some embodiments, the lever member has two pressing ends that respectively extend to two sides of the heat dissipation member and are respectively used to press on the two pressing elastic elements. The pressing ends of the lever member are located above the lever acting portion, and the lever acting portion forms a recess that opens upward and accommodates the pressing ends of the lever member.

[0009] In some embodiments, the pressing ends of the lever member are located below the lever acting portion of the pressing elastic element, and a connecting rod is connected between the pressing ends and the lever acting portion.

[0010] In some embodiments, the radiator module includes two lever members respectively located at two sides of the heat dissipation member, and each lever member has one pushed end and one pressing end.

[0011] In some embodiments, the guiding shielding cover is formed with a guiding groove extending vertically, and the pressing elastic element is provided with a guiding pin that can slide vertically and correspondingly be accommodated in the guiding groove.

[0012] In some embodiments, the guiding pin is formed by extending from a pivot rod pivotally connected between the pressing elastic element and the connecting rod.

[0013] In some embodiments, an upper frame portion disposed at the top of the radiator is integrally connected between the two pressing elastic elements, and the pressing elastic element and the upper frame portion together form a pressing frame.

[0014] In some embodiments, the heat dissipation member further has a acting bump, and the elastic supporting portion of the supporting elastic element supports upwardly on the acting bump.

[0015] In some embodiments, an end frame portion is integrally connected between the two supporting elastic elements, and the supporting elastic element and the end frame portion together form a supporting frame.

[0016] In some embodiments, the cover body of the guiding shielding cover has a top wall and a side wall. The upper radiator bracket is assembled on the top wall of the cover body, and the upper radiator bracket has a side wall. The lever member of the upper radiator module is pivotally connected to the side wall of the upper radiator bracket, and the lever member of the lower radiator module is pivotally connected to the side wall of the cover body.

[0017] In some embodiments, the cover body of the guiding shielding cover has a top wall and a side wall. The upper radiator bracket is integrally formed on the top wall of the cover body, and the upper radiator bracket has a side wall. The lever member of the upper radiator module is pivotally connected to the side wall of the upper radiator bracket, and the lever member of the lower radiator module is pivotally connected to the side wall of the cover body.

[0018] In some embodiments, the heat coupling portion of the heat sink has a heat conducting pad located at the bottom.

[0019] Thus, in some embodiments, the connector assembly of the present invention includes the connector assembly, socket connector, and pluggable module described above. The socket connector is disposed at the rear section of the guiding shield. The pluggable module is used to be inserted into the insertion space of the guiding shield to dock with the socket connector. When the pluggable module is inserted into the insertion space of the guiding shield, it provides the external force for pushing the pushed end of the lever member, and through the lever member, the pressing elastic element pushes the heat sink downward to the lower acting position, so that the heat coupling portion of the heat sink contacts the surface of the pluggable module.

[0020] By providing the pressing elastic element (and the supporting elastic element) at the side of the heat sink, the volume occupied by the heat sink is reduced. In addition, the pressing elastic element and the supporting elastic element, as individual and independent elements, directly act on the heat sink respectively to apply elastic forces in different directions to the heat sink, thereby making the heat sink move more balanced and stable. Further, by respectively disposing two pressing elastic elements and two supporting elastic elements on two sides of the heat sink, and each of the pressing elastic element and the supporting elastic element has at least two force application points (or support points) in the front and rear directions for the heat sink, the movement of the heat sink can be made more balanced and stable.

[0179] Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

[0180] Refer to Figures 1 to 3 , a first embodiment of the connector assembly 100 of the present invention includes a guiding shield 1, a socket connector 2, a pluggable module 3, an upper heat sink module 4, and a lower heat sink module 5.

[0181] The guiding shield 1 is, for example, constructed by stamping and bending a metal sheet through a mold. The guiding shield 1 is used to be disposed on a circuit board (not shown) and extends along a front - rear direction D1 (the arrow direction is forward and the reverse direction is backward). The guiding shield 1 includes a shield body 11, an upper heat sink bracket 12 and a lower heat sink bracket 13 assembled to the shield body 11. The shield body 11 has a top wall 111, a bottom wall 112 spaced from the top wall 111 along an up - down direction D2 (the arrow direction is up and the reverse direction is down), two side walls 113 spaced from each other along a left - right direction D3 (the arrow direction is right and the reverse direction is left) and connected between the top wall 111 and the bottom wall 112, a rear wall 114 connected to the rear edges of the top wall 111 and the two side walls 113, and a plurality of pins 115 extending downward from the plurality of side walls 113 and the rear wall 114 and adapted to be fixed on the circuit board and / or connected to a ground trace (not shown).

[0182] Refer to Figures 1 to 5, the upper radiator bracket 12 is assembled on the top wall 111 of the cover body 11. The upper radiator bracket 12 has an upper wall 121, a lower wall 122 and two side walls 123. The upper wall 121, the lower wall 122 and the two side walls 123 together define an inner accommodation space 124. The top wall 111 of the cover body 11 has four holding pieces 113a extending upward. Each of the two side walls 113 has a slot 113c with an opening facing forward. Each holding piece 113a is formed with a holding groove 113b with an opening facing forward. The top wall 111 of the cover body 11 also has a snap groove 111a located behind the upper window 111b. The upper radiator bracket 12 also has insertion pieces 125 respectively extending downward and backward from the two side walls 123 and correspondingly inserted backward into the corresponding slots 113c, and a snap piece 126 extending backward and downward from the rear end of the lower wall 122 and correspondingly snapped into the snap groove 111a. In addition, two slits 122b are formed in the lower wall 122 of the upper radiator bracket 12 adjacent to the two side walls 123 and along the front-rear direction D1. The two front ones of the four holding pieces 113a penetrate through the two slits 122b, and the part of the lower wall 122 in front of the two slits 122b and the rear end of the lower wall 122 are respectively snapped into the holding grooves 113b of the multiple holding pieces 113a of the cover body 11, thereby firmly assembling the upper radiator bracket 12 on the top wall 111 of the cover body 11.

[0183] The lower radiator bracket 13 is assembled inside the cover body 11 and together with the cover body 11 defines an upper insertion space 14 and a lower insertion space 15. The lower radiator bracket 13 has an upper wall 131 and a lower wall 132 which are opposite up and down and a front wall 133 connected to the front edges of the upper wall 131 and the lower wall 132. The upper wall 131, the lower wall 132 and the front wall 133 together define an inner accommodation space 134. Each side wall 113 of the cover body 11 also has a plurality of through holes 113e. The lower radiator bracket 13 also has a plurality of fixing flaps 136 extending laterally from the upper wall 131 and the lower wall 132. A plurality of positioning pieces 135 are correspondingly inserted into the positioning holes 113d of the two side walls 113 of the cover body 11. The plurality of fixing flaps 136 pass through the through holes 113e of the two side walls 113 of the cover body 11 and are bent, thereby firmly assembling and arranging the lower radiator bracket 13 inside the cover body 11.

[0184] In this first embodiment, the rear section of the upper insertion space 14 and the rear section of the lower insertion space 15 communicate with each other. The upper insertion space 14 has an upper socket 141 facing forward; the lower insertion space 15 has a lower socket 151 facing forward, and a bottom opening 152 which is defined by the bottom wall 112, the side walls 113 and the rear wall 114 of the cover body 11 and faces downward and is located behind the bottom.

[0185] The socket connector 2 is used to be disposed on the circuit board, and is disposed in the rear section of the upper plugging space 14 and the rear section of the lower plugging space 15 of the guiding shielding cover 1 through the bottom opening 152. The socket connector 2 has an insulating housing 21 and a plurality of terminals 22 disposed on the housing 21. The housing 21 has two docking slots 211 facing forward and corresponding to the upper plugging space 14 and the lower plugging space 15 respectively.

The tail portions 222 of the plurality of terminals 22 are respectively used to be disposed on the circuit board.

[0186] The pluggable module 3 has a housing member 31 and a plugging circuit board 32. The housing member 31 has a plugging portion 311 for inserting into the upper plugging space 14 and the lower plugging space 15 from the upper socket 141 and the lower socket 151. The plugging circuit board 32 is protrudingly disposed on the plugging portion 311 and is used to be inserted into the corresponding docking slot 211. Each side wall 113 of the housing 11 of the guiding shielding cover 1 has two openings 113f corresponding to the upper plugging space 14 and the lower plugging space 15 respectively. An inwardly extending elastic piece 113g extending obliquely inward and backward is constructed at each opening 113f. Locking grooves 311a corresponding to the inwardly extending elastic pieces 113g are provided on the left and right sides of the plugging portion 311 of the pluggable module 3. The plurality of inwardly extending elastic pieces 113g at the plurality of openings 113f are used to cooperate with the locking grooves 311a of the pluggable module 3 inserted into the upper plugging space 14 or the lower plugging space 15 to produce a locking effect. In addition, an alignment structure 311b is further formed at the front top of the plugging portion 311 of the housing member 31. An upper window 111b communicating with the upper plugging space 14 is formed on the top wall 111 of the housing 11, and an upper stop portion 111c extending downward from the rear section of the upper window 111b into the upper plugging space 14 is formed. A corresponding window 122a corresponding to the upper window 111b is formed on the lower wall 122 of the upper radiator bracket 12. A lower window 132a communicating the inner accommodation space 134 with the lower plugging space 15 is formed on the lower wall 132 of the lower radiator bracket 13, and a lower stop portion 132b extending downward from the rear section of the lower window 132a into the lower plugging space 15 is formed. The upper stop portion 111c and the lower stop portion 132b are used to stop at the alignment structure 311b of the pluggable module 3 to limit its insertion position.

[0187] In this embodiment, the guiding shield 1 of the connector assembly 100 can be disposed in a mounting hole (not shown in the figure) of a chassis (not shown in the figure). The guiding shield 1 further has a plurality of first grounding members 16 provided at the front end of the shield body 11, and a second grounding member 17 provided at the front section of the lower radiator bracket 13. The first grounding members 16 have a plurality of elastic fingers 161 extending rearward from the front end of the shield body 11 and distributed on the outer side and the inner side of the shield body 11. Among the plurality of elastic fingers 161, those located on the outer side of the shield body 11 are used to contact the edge of the mounting hole of the chassis, and those located on the inner side of the shield body 11 are used to contact the pluggable module 3. The second grounding member 17 has a sheet body 171 provided on the front side of the front wall 133 of the lower radiator bracket 13, and two grounding sheets 172 respectively extending rearward from the upper edge and the lower edge of the sheet body 171 to extend into the upper plugging space 14 and the lower plugging space 15. Each grounding sheet 172 has a plurality of elastic fingers 172a extending rearward and used to contact the pluggable module 3.

[0188] It should be noted that although in this first embodiment the guiding shield 1 has two plugging spaces (the upper plugging space 14 and the lower plugging space 15) corresponding to the upper radiator module 4 and the lower radiator module 5 and two radiator brackets (the upper radiator bracket 12 and the lower radiator bracket 13), in other variant embodiments, the guiding shield 1 may also have only one plugging space and one radiator bracket corresponding to one radiator module, or have three or more plugging spaces and three or more radiator brackets corresponding to three or more radiator modules, not limited to this first embodiment.

[0189] Refer to Figures 2 to 4 and Figures 6 to 7, the upper radiator module 4 is installed in the accommodation space 124 of the upper radiator bracket 12 and corresponds to the upper plugging space 14. The upper radiator module 4 includes a heat dissipation member 41, two pressing elastic elements 421, a lever member 43, and two supporting elastic elements 441. The heat dissipation member 41 has a substrate 411, and a plurality of heat dissipation fins 412 that extend along the front-rear direction D1 and are arranged side by side and integrally formed upward from the top surface of the substrate 411 in the left-right direction D3. It should be noted that in a variant embodiment, the plurality of heat dissipation fins 412 may also be a plurality of plate bodies that are buckled with each other and are arranged on the top surface of the substrate 411 in a manner such as welding. The bottom of the substrate 411 has a thermal coupling portion 411a facing downward, and the thermal coupling portion 411a is used to pass through the corresponding opening 122a and the upper opening 111b to contact the pluggable module 3 inserted into the upper plugging space 14, thereby enhancing the heat dissipation performance of the upper radiator module 4. In this embodiment, a heat conduction pad 411b for contacting the pluggable module 3 is provided at the bottom of the thermal coupling portion 411a. The heat conduction pad 411b can be, for example, a thermal interface material, and the thermal interface material can be selected from a combination of materials having characteristics such as high thermal conductivity, high flexibility, compressibility, insulation, wear resistance, etc. For example, it can be selected from a combination of a base material and a phase change material.

[0190] The two pressing elastic elements 421 are respectively arranged at the left and right side surfaces of the heat dissipation element 41. The outer side surfaces on the left and right sides of the heat dissipation element 41 each have two acting bumps 413 formed to protrude outward. Moreover, the two acting bumps 413 on each side are arranged at intervals, one in front of the other. Each pressing elastic element 421 has two heat dissipation element acting parts 421a located at the front and rear ends for pushing the heat dissipation element 41 and a lever acting part 421b located in the middle for being pressed by the lever element 43. The heat dissipation element acting parts 421a of the two pressing elastic elements 421 respectively press downward from above the multiple acting bumps 413 to push the heat dissipation element 41, and the design of the lever acting part 421b located in the middle can balance the acting forces between the elements. In this first embodiment, an upper frame part 422 arranged at the top of the heat dissipation element 41 is integrally connected between the two pressing elastic elements 421. The upper frame part 422 includes a front frame 422a connected between the heat dissipation element acting parts 421a located in front of the two pressing elastic elements 421, and a rear frame 422b connected between the heat dissipation element acting parts 421a located behind the two pressing elastic elements 421. The front frame 422a and the rear frame 422b each have lower folding pieces 422c located on the left and right sides and bent downward to be accommodated in the accommodation grooves 416 at the top of the heat dissipation element 41, thereby strengthening the limiting and stability with the heat dissipation element 41. The two pressing elastic elements 421 and the front frame 422a and the rear frame 422b of the upper frame part 422 together form a pressing frame 42, thereby increasing the balance of the acting forces between the two pressing elastic elements 421 with each other.

The two pressing - ends 433 respectively extend to the two side surfaces of the heat dissipation element 41 and are respectively used for pressing on the lever acting parts 421b of the two pressing elastic elements 421. The pressing - ends 433 of the two lever elements 43 are respectively located above the lever acting parts 421b of the two pressing elastic elements 421, and the lever acting parts 421b form recesses opening upward and accommodating the pressing - ends 433 of the corresponding lever elements 43.

The portions of the two supporting elastic elements 441 at the rear ends of the assembling recesses 441b are respectively snapped into the assembling grooves 122d of the two assembling pieces 122c, thereby further strengthening the stability of the two supporting elastic elements 441.

[0193] Refer to Figures 2 to 4 and Figures 8 to 9 As shown in FIGS. 4 and 5, the lower radiator module 5 is installed in the internal accommodation space 134 of the lower radiator bracket 13 and corresponds to the lower plug-in space 15. The lower radiator module 5 is generally the same in structure as the upper radiator module 4 and includes a heat sink 51, two pressing elastic elements 521, a lever member 53, and two supporting elastic elements 541. The heat sink 51 has a substrate 511, and a plurality of heat dissipation fins 512 extending along the front and rear direction D1 and arranged side by side and integrally formed upward from the top surface of the substrate 511 in the left and right direction D3.

The heat coupling portion 511a is used to pass through the lower opening window 132a to contact the pluggable module 3 inserted into the lower plug-in space 15, thereby enhancing the heat dissipation performance of the lower radiator module 5. In this embodiment, a heat conducting pad 511b for contacting the pluggable module 3 is provided at the bottom of the heat coupling portion 511a.

[0194] The two pressing elastic elements 521 are respectively arranged on the left and right side surfaces of the heat dissipation element 51. The outer side surfaces on the left and right sides of the heat dissipation element 51 each have two acting bumps 513 formed to protrude outward. Moreover, the two acting bumps 513 on each side are arranged at intervals, one in front of the other. Each pressing elastic element 521 has two heat dissipation element acting parts 521a located at the front and rear ends and used to push the heat dissipation element 51, and a lever acting part 521b located in the middle and used to be pressed by the lever member 53. The heat dissipation element acting parts 521a of the two pressing elastic elements 521 respectively press downward from above the multiple acting bumps 513 to push the heat dissipation element 51, and the design of the lever acting part 521b located in the middle can balance the acting forces between the elements. In this first embodiment, an upper frame part 522 is integrally connected between the two pressing elastic elements 521 and is arranged at the top of the radiator. The upper frame part 522 includes a front frame 522a connected between the heat dissipation element acting parts 521a located in front of the two pressing elastic elements 521, and a rear frame 522b connected between the heat dissipation element acting parts 521a located behind the two pressing elastic elements 521. The front frame 522a and the rear frame 522b each have lower folding pieces 522c located on the left and right sides and bent downward to be accommodated in the accommodation grooves 516 at the top of the heat dissipation element 51, thereby strengthening the limit and stability with the heat dissipation element 51. The two pressing elastic elements 521 and the front frame 522a and the rear frame 522b of the upper frame part 522 together form a pressing frame 52, thereby increasing the balance of the acting forces between the two pressing elastic elements 521 with each other.

[0195] The lever member 53 has a pivot rod 531 extending along the left-right direction D3 and pivotally connected at both ends to the pivot holes 113j on the side walls 113 of the cover body 11 of the guiding shielding cover 1, two pushed ends 532 extending backward and downward from the pivot rod 531 and used to be pushed, and two pressing ends 533 extending forward and downward from the pivot rod 531 and used to press downward on the pressing elastic elements 521. The two pushed ends 532 are connected to each other and can extend into the lower plugging space 15 through the lower opening window 132a. The two pressing ends 533 respectively extend to the two side surfaces of the heat dissipation element 51 and are respectively used to press on the lever acting parts 521b of the two pressing elastic elements 521. The pressing ends 533 of the two lever members 53 are respectively located above the lever acting parts 521b of the two pressing elastic elements 521. The lever acting parts 521b form concave parts with upward openings to accommodate the pressing ends 533 of the corresponding lever members 53. In addition, in this first embodiment, the heat dissipation element 51 is formed with a first avoidance groove 514 with an upward opening to avoid the pivot rod 531, and a second avoidance groove 515 penetrating vertically to allow the two pushed ends 532 to pass downward through.

[0196] The two support elastic elements 541 are respectively disposed on the left and right side surfaces of the heat dissipation member 51 and face upward to elastically support the heat dissipation member 51. Each support elastic element 541 has two elastic support portions 541a arranged front and rear and facing upward to support the heat dissipation member 51. The elastic support portions 541a of the two support elastic elements 541 respectively abut upward from below the plurality of acting bumps 513 to support the heat dissipation member 51. A plurality of assembly holes 113h are formed in each side wall 113 of the cover body 11. An end frame portion 542 in a U shape is integrally connected between the two support elastic elements 541. The support elastic elements 541 and the end frame portion 542 together form a support frame 54. The end frame portion 542 has a plurality of assembly pieces 542a protruding outward along the left-right direction D3 and correspondingly inserted into the plurality of assembly holes 113h. Through the end frame portion 542, the balance between the two support elastic elements 541 can be increased and the two support elastic elements 541 can be firmly fixed. In addition, each of the two support elastic elements 541 is formed with an assembly recess 541b located inside. The lower wall 132 of the lower radiator bracket 13 has two assembly pieces 132c extending upward from both sides of the lower window 132a and correspondingly passing through the assembly recesses 541b of the two support elastic elements 541. Each assembly piece 132c is formed with an assembly groove 132d opening backward. The portions of the two support elastic elements 541 at the rear ends of the assembly recesses 541b are respectively snapped into the assembly grooves 132d of the two assembly pieces 132c, thereby further strengthening the stability of the two support elastic elements 541.

[0197] Refer to Figures 2 to 4 and Figure 10 , the heat dissipation member 41(51) can, through the action of the lever member 43(53), move between a higher release position and a lower acting position relative to the insertion space (the upper insertion space 14, the lower insertion space 15), and in the lower acting position, the thermal coupling portion 411a(511a) extends into the insertion space (the upper insertion space 14, the lower insertion space 15) and can contact the surface of the pluggable module 3. It should be noted that when the heat dissipation member 41(51) is in the release position, it is limited in the upward direction by the upper wall 121 of the upper radiator bracket 12 and the upper wall 131 of the lower radiator bracket 13. When the heat dissipation member 41(51) is in the acting position, it is limited in the downward direction by the support elastic elements 441(541). In addition, when the heat dissipation member 41(51) is in the release position, the thermal coupling portion 411a(511a) may, for example, not extend into the insertion space (the upper insertion space 14, the lower insertion space 15) or be at a height where it cannot contact the pluggable module 3.

[0198] Such as Figure 4As shown, when the pluggable module 3 has not been fully inserted into the plugging space (the upper plugging space 14 and the lower plugging space 15), and the pushed end 432 (532) of the lever member 43 (53) is not pushed by the external force generated by the pluggable module 3, the supporting elastic element 441 (541) supports the heat sink 41 (51) upwardly so that the heat sink 41 (51) is located at the release position, and the heat sink 41 (51) acts on the lever member 43 (53) through the pressing elastic element 421 (521) so that the pushed end 432 (532) of the lever member 43 (53) extends into the plugging space (the upper plugging space 14 and the lower plugging space 15); As Figure 10 As shown, when the pluggable module 3 is fully inserted into the plugging space (the upper plugging space 14 and the lower plugging space 15), and the pushed end 432 (532) of the lever member 43 (53) is pushed backward by the external force generated by the alignment structure 311b of the pluggable module 3 to cause the lever member 43 (53) to rotate, the pressing end 433 (533) of the lever member 43 (53) presses downwardly on the pressing elastic element 421 (521), so that the pressing elastic element 421 (521) pushes the heat sink 41 (51) downwardly to the acting position where the heat coupling portion 411a (511a) can contact the pluggable module 3, and the heat sink 41 (51) compresses the supporting elastic element 441 (541) downwardly. The compressed supporting elastic element 441 (541) can provide a restoring force to cause the heat sink 41 (51) to return to the release position when the external force is released. Thus, when the pluggable module 3 exits the plugging space (the upper plugging space 14 and the lower plugging space 15), the supporting elastic element 441 (541) can push the heat sink 41 (51) upwardly and cause the heat sink 41 (51) to return to the release position, and the pushed end 432 (532) of the lever member 43 (53) extends into the plugging space (the upper plugging space 14 and the lower plugging space 15) again.

[0199] Refer to Figure 11 And Figure 14, the difference between a second embodiment of the connector assembly 100 of the present invention and the first embodiment is that the side walls 123 of the upper radiator bracket 12 of the guiding shield 1 are integrally formed on the left and right sides of the top wall 111 of the housing 11 and extend out of the top wall 111 coplanarly with the side walls 113. The number of lever members 43' of the upper radiator module 4 is two each and are respectively located at two side surfaces of the heat sink member 41, and the number of lever members 53' of the lower radiator module 5 is two each and are respectively located at two side surfaces of the heat sink member 51. Each lever member 43' (53') has a pushed end 432 (532) and a pressing end 433 (533). The pressing ends 433 (533) of the two lever members 43' (53') are located below the lever action portions 421b (521b) of the two pressing elastic elements 421' (521'). And, a connecting rod 45 (55) is pivotally connected between each pressing end 433 (533) and the corresponding lever action portion 421b (521b) in a pivotal manner, so that the pressing end 433 (533) can press downwardly on the corresponding lever action portion 421b (521b) through the connecting rod 45 (55). The side walls 123 of the upper radiator bracket 12 of the guiding shield 1 and the side walls 113 of the housing 11 are respectively formed with guiding grooves 123b (113i) extending up and down and corresponding to the upper radiator module 4 and the lower radiator module 5. The pressing elastic elements 421' (521') are provided with guiding pins 461 (561) that can slide up and down and are correspondingly received in the guiding grooves 123b (113i). Among them, the pressing elastic elements 421' (521'), the connecting rods 45 (55), the lever members 43' (53') and the pivot holes 123c (113j) of the guiding shield 1 are pivotally connected to each other through a plurality of pivot rods 46 (56), and the guiding pins 461 (561) are formed by extending outward from the pivot rods 46 (56) pivotally connected between the pressing elastic elements 421' (521') and the connecting rods 45 (55).

[0200] In addition, the heat sink acting portions 421a (521a) of the two pressing elastic elements 421' (521') directly act on the heat sink fins 412 (512) at the left and right two side surfaces of the heat sink member 41 (51). And, the upper frame portion 422' (522') connected between the two pressing elastic elements 421' (521') is not divided into a front frame 422a (522a) and a rear frame 422b (522b) (see Figure 7 , Figure 9) and is constructed as a complete plate body. Furthermore, the end frame portion 442'(542') connected between the two support elastic elements 441'(541') has a rectangular frame structure, and the support frame 44 jointly formed by the support elastic element 441' and the end frame portion 442' of the upper radiator module 4 is sandwiched between the acting convex block 413 of the heat dissipation member 41 and the top wall 111 of the cover body 11 of the guiding shielding cover 1. The support frame 54 jointly formed by the support elastic element 541' and the end frame portion 542' of the lower radiator module 5 is sandwiched between the acting convex block 513 of the heat dissipation member 51 and the lower wall 132 of the lower radiator bracket 13.

[0201] In summary, in the present invention, by means of the pressing elastic element 421(521) (and the support elastic element 441(541)) provided on the side surface of the heat dissipation member 41(51), the volume occupied by the heat dissipation member 41(51) is reduced. In addition, the pressing elastic element 421(521) and the support elastic element 441(541) are individual independent elements and directly act on the heat dissipation member 41(51) respectively to apply elastic forces in different directions to the heat dissipation member 41(51), thereby making the heat dissipation member 41(51) more balanced and stable when moving. Further, by respectively arranging two pressing elastic elements 421(521) and two support elastic elements 441(541) on two side surfaces of the heat dissipation member 41(51), and each of the pressing elastic element 421(521) and the support elastic element 441(541) has at least two front and rear force application points (or support points) for the heat dissipation member 41(51), the movement of the heat dissipation member 41(51) can be made more balanced and stable.

[0202] However, as described above, it is only an embodiment of the present invention, and the scope of implementation of the present invention cannot be limited thereby. All simple equivalent changes and modifications made according to the claims and the content of the specification of the present invention still fall within the scope covered by the patent of the present invention.
