Technical Field

[0001] The present invention relates to a connector assembly, in particular to a connector assembly provided with a radiator. Background Art

[0002] Chinese invention patent publication number CN104977664B (corresponding to U.S. invention patent publication number US9,820,382) discloses a connector assembly, wherein the connector of the connector assembly has a mounting opening formed on a bottom shell, the base of the heat sink of the connector assembly is mounted on the mounting opening of the bottom shell, and an elastic retaining member is formed at the edge of the mounting opening of the bottom shell, which is used to elastically retain the base of the heat sink on the mounting opening, so that the heat sink can overcome the elastic force of the elastic retaining member and move within a predetermined range in the thickness direction of the base. However, the structure disclosed in this case is to enable the elastic movement of the heat sink, which is not applicable to connector assemblies where the heat sink does not need to move. Moreover, the disclosed structure is complicated and inconvenient when assembling and disassembling the heat sink. Summary of the Invention

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

[0004] Therefore, in some embodiments of the connector assembly of the present invention, the connector assembly includes a guide shield and a heat sink. The guide shield has a housing space and a wall forming the housing space, the wall having a window communicating with the housing space, and two snap-fit ​​plates disposed on either side of the window and extending away from the housing space. Each snap-fit ​​plate is integrally formed with a snap-fit ​​protrusion having a guide portion and a snap-fit ​​portion. The height of the guide portion protruding from the snap-fit ​​plate gradually increases as the distance from the housing space decreases. The snap-fit ​​portion is located at the end surface of the guide portion that is closest to the housing space. The radiator has a substrate and a thermal coupling portion provided on the inner side surface of the substrate facing the accommodating space. During the process of assembling the radiator to the guide shielding cover, the substrate presses against the guiding portions of the snapping protrusions of the two snapping plates to elastically move the two snapping plates. When the substrate passes over the guiding portions of the snapping protrusions of the two snapping plates, the snapping portions of the snapping protrusions of the two snapping plates are snapped to the substrate, and the thermal coupling portion extends into the accommodating space through the window.

[0005] In some embodiments, the snapping portions of the snapping protrusions of the two snapping plates are snapped to the outer side surface of the base plate facing away from the accommodating space, and the snapping protrusions are long strip-shaped convex bumps constructed on the outer side surfaces of the two snapping plates facing away from each other, and the surface of the guide portion of the snapping protrusion is an arc-shaped surface with a gradually increasing protruding height relative to the snapping plate.

[0006] In some embodiments, the substrate of the heat sink is formed with two slots for the two snap-on plates to pass through, and the snap-on protrusions on the two snap-on plates pass through the two slots so that the snap-on portions of the two snap-on protrusions are snap-on to the outer side surface of the substrate.

[0007] In some embodiments, the wall of the guide shield further has an auxiliary inserting piece disposed beside each buckle plate and inserted into the slot.

[0008] In some embodiments, the snapping portions of the snapping protrusions of the two snapping plates are snapped to the outer side surface of the base plate facing away from the accommodating space, and the snapping protrusions are long strip-shaped convex bumps constructed on the inner side surfaces facing each other of the two snapping plates, and the surface of the guide portion of the snapping protrusion is an arc-shaped surface with a gradually increasing protruding height relative to the snapping plate.

[0009] In some embodiments, the substrate of the heat sink is formed with two recesses corresponding to the two snap-on plates, and the snap-on protrusions on the two snap-on plates pass through the two recesses so that the snap-on portions of the two snap-on protrusions are snap-oned to the outer side surface of the substrate.

[0010] In some embodiments, the wall is provided with a spring sheet facing outward and elastically pressing against the inner side surface of the base plate of the heat sink.

[0011] In some embodiments, each snap plate is formed with a plurality of air flow holes.

[0012] In some embodiments, the substrate is formed with two snap-on grooves corresponding to the two snap-on plates respectively, and the snap-on parts of the snap-on protrusions of the two snap-on plates are snapped to the two snap-on grooves of the substrate respectively, and the snap-on protrusions are long strip-shaped protrusions constructed on the inner sides of the two snap-on plates facing each other.

[0013] In some embodiments, each buckling plate further has two lugs integrally formed at two side edges, and the two lugs can be bent to extend into the corresponding buckling grooves.

[0014] In some embodiments, the heat sink is a first heat sink, and the connector assembly further includes a second heat sink and an elastic fastener. The second heat sink can be elastically movably assembled on the other wall of the guide shield cover opposite to the wall relative to the accommodating space through the elastic fastener, and the second heat sink has a thermal coupling portion extending into the accommodating space.

[0015] In some embodiments, the second heat sink has a substrate assembled on the other wall and provided with the thermal coupling portion, and the elastic fastener has an elastic pressing portion that elastically presses against the outer side surface of the substrate, and an assembly portion extending from the elastic pressing portion and assembled to the guide shielding cover.

[0016] The two snap-fitting plates of the guide shield of the present invention are integrally provided with snap-fitting protrusions. Each snap-fitting protrusion includes a guide portion and a snap-fitting portion. The height of the guide portion from the snap-fitting plate protrusion gradually increases as the distance from the accommodating space decreases. Thus, the heat sink can be smoothly pushed directly into the assembly and snap-fitted with the snap-fitting portions of the two snap-fitting protrusions through the guide portions of the two snap-fitting plates. Moreover, the heat sink can be quickly disassembled by pushing and pulling the two snap-fitting plates. In addition, the spring sheet pressed on the heat sink can increase the stability of the heat sink after assembly and provide a thrust in the disassembly direction when disassembling the heat sink, further making the disassembly of the heat sink more convenient and easy. In addition, the first heat sink and the second heat sink are provided for the accommodating space of the guide shield, which greatly improves the heat dissipation efficiency.

[0104] Before the present invention is described in detail, it should be noted that similar elements are denoted by the same reference numerals in the following description.

[0105] See Figures 1 to 4A first embodiment of a connector assembly 100 of the present invention is suitable for being mounted on a circuit board 200 and for being plugged into a pluggable module 300. The pluggable module 300 includes a housing 301, a plug board 302, and a cable 303. The housing 301 includes a plug portion 301a. The plug board 302 is disposed at the end of the plug portion 301a and has a plurality of contact fingers 302a. The cable 303 is disposed in the housing 301 and mechanically and electrically connected to the plug board 302. The connector assembly 100 includes a receptacle connector 1, a guide shield 2, a lower heat sink 3 (first heat sink), an upper heat sink 4 (second heat sink), and an elastic fastener 5. It should be noted that the number of the socket connector 1, the guide shield 2, the lower heat sink 3, the upper heat sink 4 and the elastic fastener 5 can be adjusted according to needs and can be stacked or combined, and is not limited to the number in the first embodiment.

[0106] The socket connector 1 (see Figure 1 ) is mechanically and electrically arranged on the circuit board 200, the socket connector 1 has an insulating base 11 and a plurality of terminals 12, the base 11 has a plug-in slot 111, these terminals 12 are arranged in the plug-in slot 111 and their tails (not shown) are electrically and mechanically connected to the circuit board 200.

[0107] The guide shield 2 is, for example, made of metal and covers the receptacle connector 1. The guide shield 2 can be formed from a metal plate by stamping and bending. The guide shield 2 extends along a front-to-back direction D1 (the arrow indicates the front direction, the reverse direction indicates the rear direction) and comprises a top wall 21, a bottom wall 22 spaced apart from the top wall 21 along a top-to-bottom direction D2 (the arrow indicates the top direction, the reverse direction indicates the bottom direction), two side walls 23 spaced apart from each other along a left-to-right direction D3 (the arrow indicates the right direction, the reverse direction indicates the left direction) and connected to the top wall 21 and the bottom wall 22, respectively, a rear wall 24 at the rear end connected to the top wall 21 and the rear edges of the side walls 23, and a plurality of pins 25 extending downward from the side walls 23 and adapted to be secured to the sockets 201 on the circuit board 200 and / or connected to ground traces. In addition, the guide shield cover 2 also has an accommodating space 26 defined and located inside by the top wall 21, the bottom wall 22, the two side walls 23 and the rear wall 24, a socket 261 located at the front end and connected to the accommodating space 26 for the pluggable module 300 to be inserted, a lower window 262 formed on the bottom wall 22 and connected to the accommodating space 26, an upper window 263 formed on the top wall 21 and extending rearward from the front section of the top wall 21 and connected to the accommodating space 26, and a bottom opening 264 located behind the bottom wall 22 and connected to the accommodating space 26.

[0108] In this first embodiment, the top wall 21, side walls 23, and rear wall 24 of the guide shield 2 are integrally constructed, while the bottom wall 22 of the guide shield 2 is assembled to the side walls 23. A dovetail recess 231 is formed at the bottom edge near the front end of each side wall 23, and each side wall 23 has two outwardly formed buckling blocks 232. The bottom wall 22 is integrally formed with two upwardly formed dovetail protrusions 221 that correspond to the dovetail recesses 231 of the side walls 23, as well as two assembly tabs 222 that are assembled to the outer sides of the side walls 23. Each assembly tab 222 has two buckling holes 222a formed therein that buckle into the buckling blocks 232 of the corresponding side walls 23, thereby enabling the bottom wall 22 to be assembled to the side walls 23.

[0109] Specifically, the receptacle connector 1 is covered by the guide shield 2 through the bottom opening 264, so that the receptacle connector 1 is located at the rear end of the accommodating space 26, but the present invention is not limited thereto. After the pluggable module 300 enters the guide shield 2 through the socket 261, the pluggable board 302 at the end of the pluggable portion 301a of the pluggable module 300 can be inserted into the plugging slot 111 of the receptacle connector 1, so that the contact fingers 302a of the pluggable board 302 contact the terminals 12 in the plugging slot 111 of the receptacle connector 1, thereby mating the pluggable module 300 with the receptacle connector 1 of the connector assembly 100. In addition, the front section of the guide shield cover 2 can be set at a mounting hole 401 of a casing 400 adjacent to the socket 261, and a plurality of grounding members 27 are provided at the socket 261 of the guide shield cover 2. The grounding members 27 have a plurality of elastic fingers 271 extending backward from the socket 261 and distributed on the outside and inside of the guide shield cover 2. Among these elastic fingers 271, those located on the outside of the guide shield cover 2 are used to contact the portion of the casing 400 located at the periphery of the mounting hole 401, and those located on the inside of the guide shield cover 2 are used to contact the pluggable module 300.

[0110] See Figures 3 to 7The bottom wall 22 of the guide shield 2 further includes two snap-fitting plates 223 disposed on either side of the lower opening 262 and extending downwardly away from the accommodating space 26. The two snap-fitting plates 223 may be integrally formed with the bottom wall 22. For example, the two snap-fitting plates 223 may be arranged side by side, facing each other along the left-right direction D3, as in the first embodiment. However, in other embodiments, they may also be arranged side by side, facing each other along the front-to-back direction D1 (as in the third embodiment). Each snap-fitting plate 223 is integrally formed with a snap-fitting protrusion 223a. It should be noted that in other embodiments, each snap-fitting plate 223 may also be formed with more than two snap-fitting protrusions 223a. The fastening protrusion 223a comprises a guide portion 223b and a fastening portion 223c. The height of the guide portion 223b protruding from the fastening plate 223 gradually increases upward as the distance from the accommodating space 26 decreases. The fastening portion 223c is located at the distal end of the guide portion 223b, located above and adjacent to the accommodating space 26. In the first embodiment, the fastening protrusion 223a is a long, rectangular convex bump protruding from the opposing outer surfaces of the two fastening plates 223 and extending along the front-to-back direction D1. The guide portion 223b of the fastening protrusion 223a is an arcuate surface whose protrusion height gradually increases relative to the fastening plate 223. The lower heat sink 3 includes a base plate 31, a plurality of heat dissipating fins 32 extending downward from an outer side surface (bottom surface) of the base plate 31 facing away from the accommodating space 26, and a thermal coupling portion 33 provided on an inner side surface (top surface) of the base plate 31 facing the accommodating space 26. Although the heat dissipating fins 32 are arranged side by side along the front-to-back direction D1 in the first embodiment, in other embodiments, the heat dissipating fins 32 may also be arranged side by side along the left-to-right direction D3.

[0111] During the process of assembling the lower heat sink 3 to the guide shield cover 2, the base plate 31 presses against the guide parts 223b of the snapping protrusions 223a of the two snapping plates 223 to elastically move the two snapping plates 223 inward along the left-right direction D3. When the base plate 31 passes over the guide parts 223b of the snapping protrusions 223a of the two snapping plates 223, the remaining surrounding parts 34 on the inner side surface of the base plate 31 except the thermal coupling part 33 will be limited by the bottom surface of the bottom wall 22, and the two snapping plates 223 are elastically reset, and the snapping parts 223c of the snapping protrusions 223a of the two snapping plates 223 are snapped to the outer side surface of the base plate 31 facing away from the accommodating space 26, so that the thermal coupling part 33 passes through the lower window 262 and extends into the accommodating space 26. Thus, the lower heat sink 3 can be smoothly pushed directly into the assembly and fastened and fixed with the fastening portions 223c of the two fastening protrusions 223a through the arc-shaped surfaces of the guide portions 223b of the two fastening protrusions 223a on the two fastening plates 223, and the lower heat sink 3 can be quickly disassembled by pushing and pulling the two fastening plates 223. In detail, in this first embodiment, since the two fastening protrusions 223a are formed on the outer side surfaces of the two fastening plates 223 that are opposite to each other, if the two fastening plates 223 are pushed inward along the left-right direction D3, the fastening portions 223c of the fastening protrusions 223a of the two fastening plates 223 can be released from the outer surface of the base plate 31, and the disassembly process is convenient and quick. In addition, refer to Figure 2 For example, the circuit board 200 may be formed with an escape opening 202 for evading the two buckle plates 223 and the heat dissipation fins 32 of the lower heat sink 3 .

[0112] In addition, in this first embodiment, the base plate 31 of the lower heat sink 3 is formed with two slots 311 extending along the front-to-back direction D1 for the two snap-fit ​​plates 223 to pass through. The snap-fit ​​protrusions 223a on the two snap-fit ​​plates 223 pass through the two slots 311, so that the snap-fit ​​portions 223c of the two snap-fit ​​protrusions 223a snap onto the outer side surfaces of the base plate 31. The two slots 311 and the two snap-fit ​​plates 223 function as alignment and position restraint. Furthermore, the bottom wall 22 of the guide shield 2 also has a plurality of auxiliary inserts 224 disposed adjacent to the two snap-fit ​​plates 223 on either side of the lower window 262 and inserted into the two slots 311. These auxiliary inserts 224 are disposed adjacent to each snap-fit ​​plate 223 and can assist in aligning with the slots 311, guiding the insertion of the lower heat sink 3, and helping to retain the lower heat sink 3 after assembly. On the other hand, each buckle plate 223 is further formed with a plurality of air flow holes 223 d. These air flow holes 223 d can allow air to pass through between the heat dissipation fins 32 of the lower heat sink 3, thereby improving the heat dissipation performance of the lower heat sink 3.

[0113] Furthermore, in this first embodiment, the bottom wall 22 is further provided with two spring clips 225 that face outward (downward) and elastically press against the inner side surface (top surface) of the base plate 31 of the lower heat sink 3 and are located in front of and behind the lower window 262, respectively. The two spring clips 225 are integrally formed to protrude outward (downward) from the bottom wall 22. By pressing against the lower heat sink 3, the spring clips 225 can increase the stability of the lower heat sink 3 after assembly and provide thrust in the disassembly direction when disassembling the lower heat sink 3, further making disassembly of the lower heat sink 3 more convenient and easy. It should be noted that the positions of the two spring clips 225 are not limited to the front and rear of the lower window 262. The positions of the two spring clips 225 can also be changed to other positions that can press against the base plate 31 of the lower heat sink 3.

[0114] See Figures 1 to 4 The upper heat sink 4 is disposed at the upper window 263 of the top wall 21 of the guide shield 2. The upper heat sink 4 comprises a base plate 41 disposed on the top wall 21, a plurality of heat dissipation fins 42 formed upward from the outer side (top) surface of the base plate 41 and arranged side by side along the left-right direction D3, and a thermal coupling portion 43 disposed on the inner side (bottom) surface of the base plate 41 and extending from the upper window 263 into the accommodating space 26. The upper heat sink 4 is assembled to the top wall 21 of the guide shield 2 via the elastic fastener 5 so as to be elastically movable relative to the accommodating space 26. The elastic fastener 5 includes two elastic pressing portions 51 extending along the left-right direction D3 and pressing against the base plate 41 of the upper heat sink 4 from above. It also includes two assembly portions 52 extending downward from both ends of the elastic pressing portions 51 and respectively engaging with the two side walls 23 of the guide shield 2. Specifically, each side wall 23 is formed with two engaging protrusions 233, and each assembly portion 52 is formed with two engaging holes 521 that engage with the corresponding engaging protrusions 233 of the side wall 23. Furthermore, the upper heat sink 4 includes two relief grooves 44 formed on the heat dissipating fins 32 to accommodate the two elastic pressing portions 51.

[0115] When the pluggable module 300 enters the guide shield 2 and docks with the socket connector 1 of the connector assembly 100, the bottom surface of the plug-in portion 301a of the housing 301 of the pluggable module 300 will contact the thermal coupling portion 33 of the lower heat sink 3, and the top surface of the plug-in portion 301a of the housing 301 of the pluggable module 300 will contact the thermal coupling portion 43 of the upper heat sink 4. The downward pressure applied causes the thermal coupling portion 43 of the upper heat sink 4 to rest snugly against the top surface of the plug-in portion 301a of the housing 301 of the pluggable module 300. Furthermore, the bottom surface of the plug-in portion 301a of the housing 301 of the pluggable module 300 rests downward against the thermal coupling portion 33 of the lower heat sink 3, thereby maintaining contact between the pluggable module 300 and the upper and lower heat sinks 4 and 3, ensuring heat dissipation performance. Thus, by providing the lower heat sink 3 (first heat sink) and the upper heat sink 4 (second heat sink) within the accommodating space 26 of the guide shield 2, heat dissipation efficiency can be significantly improved. Furthermore, it should be noted that although the lower heat sink 3 (first heat sink) and the upper heat sink 4 (second heat sink) are respectively disposed at the bottom and top in the first embodiment, in other embodiments, the first heat sink (lower heat sink 3), the second heat sink (upper heat sink 4), and the corresponding structures on the guide shield 2 may also be disposed on other sides of the guide shield 2. In other words, the "lower" and "upper" heat sinks described herein are merely for ease of understanding and reading, and should not be used to limit the placement of the aforementioned components.

[0116] Furthermore, in this embodiment, the top wall 21 of the guide shield 2 has a downwardly extending, bent stop 211 formed at the rear edge of the upper window 263. The pluggable module 300's insertion portion 301a also has a stop surface 301b corresponding to the stop 211. When the pluggable module 300 enters the guide shield 2 and mates with the receptacle connector 1 of the connector assembly 100, the stop 211 stops at the stop surface 301b, thereby positioning the pluggable module 300 and the connector assembly 100 relative to each other. Furthermore, each side wall 23 of the guide shield cover 2 also has a locking piece 234 extending inward, and the plug-in portion 301a also has two locking recesses 301c formed on both sides and corresponding to the locking pieces 234 of the two side walls 23 respectively. When the pluggable module 300 and the connector assembly 100 are docked with each other, the two locking pieces 234 are snapped into the two locking recesses 301c to lock the pluggable module 300 and the connector assembly 100 to each other.

[0117] See Figures 8 to 11A second embodiment of the connector assembly 100 of the present invention differs from the first embodiment in that the snap-fit ​​protrusions 223a are elongated protrusions formed on the inner facing surfaces of the two snap-fit ​​plates 223. During assembly of the lower heat sink 3 to the guide shield 2, the base plate 31 abuts against the guide portions 223b of the snap-fit ​​protrusions 223a of the two snap-fit ​​plates 223, elastically moving the two snap-fit ​​plates 223 outward along the left-right direction D3. After the base plate 31 passes over the guide portions 223b of the snap-fit ​​protrusions 223a of the two snap-fit ​​plates 223, the two snap-fit ​​plates 223 elastically return to their original positions, and the snap-fit ​​portions 223c of the snap-fit ​​protrusions 223a of the two snap-fit ​​plates 223 snap onto the outer surface of the base plate 31 facing away from the accommodating space 26, allowing the thermal coupling portion 33 to extend through the lower opening 262 into the accommodating space 26. Specifically, in the second embodiment, since the two fastening protrusions 223a are formed on the inner side surfaces of the two fastening plates 223 facing each other, if the two fastening plates 223 are pushed outward along the left-right direction D3, the fastening portions 223c of the fastening protrusions 223a of the two fastening plates 223 can be released from the outer side surface of the base plate 31. Furthermore, the base plate 31 of the lower heat sink 3 is formed with two recesses 312 corresponding to the two fastening plates 223. The fastening protrusions 223a on the two fastening plates 223 pass through the two recesses 312, so that the fastening portions 223c of the two fastening protrusions 223a are fastened to the outer side surface of the base plate 31. The two recesses 312 and the two fastening plates 223 function as alignment and limiting elements.

[0118] See Figures 12 to 15 A third embodiment of the connector assembly 100 of the present invention differs from the first embodiment in that the two snap-fit ​​plates 223 are arranged side by side, facing each other, along the front-to-back direction D1. Furthermore, two snap-fit ​​grooves 313 corresponding to the two snap-fit ​​plates 223 and extending along the left-right direction D3 are formed on the front and rear edges of the base plate 31 of the lower heat sink 3. The snap-fit ​​protrusions 223a' of the two snap-fit ​​plates 223 snap onto the upper edges of the two snap-fit ​​grooves 313 of the base plate 31, respectively. The snap-fit ​​protrusions 223a' are elongated, strip-shaped tabs formed on the inner sides of the two snap-fit ​​plates 223, facing each other, and extending along the left-right direction D3. In addition, each snap-on plate 223 further has two lugs 223e integrally formed at both side edges. The two lugs 223e can be slightly bent to extend into the corresponding snap-on grooves 313, thereby enhancing the assembly stability between the lower heat sink 3 and the snap-on plate 223.

[0119] See Figures 16 and 17In a variation of the third embodiment, the thermal coupling portion 33 of the lower heat sink 3 may further include a thermal pad 35. The thermal pad 35 can fully fill the seams or gaps between the contact surfaces to reduce the contact thermal resistance between the contact surfaces. The thermal pad 35 may be a thermal interface material (TIM). The material may be selected from a combination of materials having properties such as high thermal conductivity, high flexibility, compressibility, insulation, and wear resistance. For example, it may be a combination of a substrate and a phase change material. For example, it may have a two-layer or more structure, with the outer substrate being a material having thermal conductivity, lubricity, wear resistance, and tear resistance (such as Teflon), while the inner layer is a phase change material. Furthermore, the thermal pad 35 may also provide electromagnetic wave shielding (EMI shielding) by varying the material combination.

[0120] In summary, the two snap-fitting plates 223 of the guide shield 2 of the present invention are integrally provided with snap-fitting protrusions 223a. Each snap-fitting protrusion 223a includes a guiding portion 223b and a snap-fitting portion 223c. The height of the guiding portion 223b protruding from the snap-fitting plate 223 gradually increases as the distance from the accommodating space 26 decreases. Thus, the guiding portions 223b of the two snap-fitting protrusions 223a on the two snap-fitting plates 223 guide the lower heat sink 3 for smooth and direct insertion and securement with the snap-fitting portions 223c of the two snap-fitting protrusions 223a. Furthermore, the lower heat sink 3 can be quickly removed by pushing and pulling the two snap-fitting plates 223. Furthermore, the spring 225 pressing against the lower heat sink 3 enhances the stability of the lower heat sink 3 after assembly and provides a thrust in the removal direction during removal, further facilitating and facilitating removal of the lower heat sink 3. In addition, the lower heat sink 3 (the first heat sink) and the upper heat sink 4 (the second heat sink) are disposed in the accommodating space 26 of the guide shield 2, thereby significantly improving the heat dissipation performance.

[0121] However, the above is merely an embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. All simple equivalent changes and modifications made according to the claims and the contents of the patent specification of the present invention are still within the scope of the patent of the present invention.
