Description

[0001] This invention is a divisional application of the application with application number 202010041372.4, application date January 15, 2020, and invention title "Connector Assembly". Technical Field

[0002] The present invention relates to a connector assembly, and particularly to a connector assembly with a liquid cooling plate. Background Art

[0003] U.S. Patent Publication No. US7,625,223 discloses a socket assembly, which includes a guiding frame, a heat sink, and a conductive gasket. The guiding frame includes a top wall and defines an inner chamber configured to receive a mating connector. The top wall defines an opening communicating with the inner chamber. The heat sink is held in the inner chamber such that when the mating connector is inserted into the inner chamber, the upper portion of the heat sink passes through the opening and the lower portion engages with the mating connector. The conductive gasket is held between the guiding frame and the heat sink. The heat sink includes a coupling portion that provides a heat conduction path for the mating connector when the mating connector is inserted into the inner chamber. The conductive gasket is configured to be compressed between the guiding frame and the heat sink so that the conductive gasket provides an electrical conduction path between the heat sink and the guiding frame. However, the heat sink disclosed in this prior art is generally a metal heat sink with heat dissipation fins, and its principle is to take out the heat through the air flow flowing between the heat dissipation fins. In a connector assembly with a higher transmission speed and greater heat generation, its heat dissipation efficiency is slightly insufficient.

[0004] Chinese Patent Publication No. CN110139534A (corresponding to U.S. Patent Publication No. US2019 / 0246523A1) discloses a cooling device, which includes a manifold and a plurality of bases. The manifold includes a housing surrounding an inner cavity for accommodating and circulating cooling liquid. Each base is individually and flexibly coupled to the housing of the manifold through a sealing and annular bellows. Each base is configured to extend outward from the bottom surface of the housing of the manifold when there is fluid pressure in the inner cavity. However, the bellows of this prior art only provides a flexible connection between the base and the manifold, and the base needs to have sufficient force to extend outward from the bottom surface of the housing of the manifold when there is fluid pressure in the inner cavity of the manifold. First, as a connection and sealing member between the base and the manifold, the bellows has a complex structure and high manufacturing difficulty. Second, since the base needs to extend outward through fluid pressure, when the fluid pressure is insufficient or unstable, it is easy to cause the outward protrusion amount of the base relative to the manifold to be insufficient, resulting in insufficient pressure of the base contacting the electrical module or even unable to contact the electrical module, thereby reducing the heat dissipation efficiency. Moreover, when multiple electrical modules need to contact the respective bases on the manifold simultaneously, in the case where the outward protrusion amount of the base relative to the manifold is insufficient and the elastic restoring force of the base relative to the manifold is insufficient, it is easy for each electrical module to be unable to contact the respective bases on the manifold due to the tolerance problems of each electrical module. Summary of the Invention

[0005] Therefore, an object of the present invention is to provide a connector assembly that can improve at least one problem in the above prior art.

[0006] Thus, in some embodiments, the connector assembly of the present invention includes a shielding cover, a liquid cooling plate, and a thermal coupling module. The shielding cover has an insertion space and a window communicating with the insertion space. The liquid cooling plate is used for the internal circulation of cooling liquid. The thermal coupling module includes a thermal coupling base, a thermal conductive interface material, a connecting bolt, and an elastic member. The thermal coupling base has a thermal coupling portion extending into the insertion space through the window. The thermal conductive interface material is compressible and sandwiched between the liquid cooling plate and the thermal coupling base. The connecting bolt is disposed between the liquid cooling plate and the thermal coupling base to connect the thermal coupling base to the liquid cooling plate so that the thermal coupling base can move away from or close to the liquid cooling plate relative to the liquid cooling plate, and the thermal conductive interface material is pre-pressed. The elastic member is disposed between the liquid cooling plate and the thermal coupling base and is used to drive the thermal coupling base to move away from the liquid cooling plate.

[0007] In some embodiments, the shielding cover has a plurality of the insertion spaces and a plurality of openings respectively corresponding to the insertion spaces. The connector assembly includes a plurality of the thermal coupling modules respectively corresponding to the insertion spaces, and the thermal coupling modules are connected to the same liquid cooling plate.

[0008] In some embodiments, the elastic member is a coil spring, and the elastic member is sleeved on the corresponding connecting bolt.

[0009] In some embodiments, the liquid cooling plate is formed with a first connection hole, the thermal coupling base is formed with a second connection hole, the connecting bolt passes through the first connection hole and the second connection hole, and the connecting bolt has a first limiting block and a second limiting block. The first limiting block and the second limiting block limit the maximum distance between the thermal coupling base and the liquid cooling plate and allow the thermal coupling base to move in the direction towards the liquid cooling plate, and the thermal conductive interface material is pre-pressed.

[0010] In some embodiments, it further includes an elastic fastener disposed on the shielding cover. The elastic fastener presses against the thermal coupling base in such a way that at least one elastic fastener corresponds to one thermal coupling base. The elastic fastener has an elastic pressing portion that presses against the corresponding thermal coupling base in a direction away from the liquid cooling plate.

[0011] In some embodiments, it further includes an elastic fastener disposed on the shielding cover. The elastic fastener has a plurality of elastic pressing portions that respectively press against a plurality of the thermal coupling bases in a direction away from the liquid cooling plate.

[0012] The liquid cooling plate in the connector assembly of the present invention has better heat dissipation performance than a general radiator. The thermal conductive interface material is pre-pressed by the connecting bolt and clamped between the liquid cooling plate and the thermal coupling base, so that the thermal conductive interface material can completely contact between the liquid cooling plate and the thermal coupling base, thereby increasing the heat transfer effect of the thermal conductive interface material and enhancing the heat dissipation and cooling effect of the liquid cooling plate. In addition, since the thermal conductive interface material is pre-pressed, it is not necessary to increase the deformation stroke amount of the thermal conductive interface material by its thickness to ensure complete contact between components. Therefore, a thinner thermal conductive interface material can be selected to reduce the thermal resistance of the thermal conductive interface material, so as to exert a greater heat transfer effect and enhance the heat dissipation and cooling effect of the liquid cooling plate. Furthermore, the compressibility and elasticity of the thermal coupling module can be improved through the connecting bolt and the elastic member, and through the independent operation of each thermal coupling module, the tolerances of different pluggable modules inserted into the shielding cover can be absorbed, so that each pluggable module can have good contact with the corresponding thermal coupling module respectively, and further improve the heat dissipation efficiency.

[0073] 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.

[0074] Refer to Figures 1 to 4 , a first embodiment of the connector assembly 100 of the present invention is applicable to covering a plurality of socket connectors 200 and is applicable to being plugged with a pluggable module 300. The connector assembly 100 includes a shielding cover 1, a liquid - cooling plate 2, and a plurality of thermal coupling modules 3. It should be noted that in this embodiment, the shielding cover 1 has a plurality of cover bodies 11 connected side by side with each other, and each cover body 11 corresponds to one of the socket connectors 200. However, in other embodiments, the shielding cover 1 may also have only one cover body 11, and the number of socket connectors 200 can also be adjusted correspondingly according to requirements.

[0075] The shielding cover 1 can be made of metal, for example. The housing 11 of the shielding cover 1 extends along a front-rear direction D1 and has a top wall 111, a bottom wall 112 spaced apart from the top wall 111 along an up-down direction D2, two side walls 113 spaced apart from each other along a left-right direction D3 and respectively connected to both sides of the top wall 111 and the bottom wall 112, and a plurality of pins 115 extending downward from the two side walls 113 and adapted to be fixed on a circuit board (not shown) and / or connected to a ground trace. The housing 11 of the shielding cover 1 further has an insertion space 116 defined by the top wall 111, the bottom wall 112 and the two side walls 113 and located inside, a front-end opening 116a located at the front end and communicating with the insertion space 116, a window 116b formed in the top wall 111 and communicating with the insertion space 116, and a bottom opening 116c located at the rear side of the bottom wall 112 and communicating with the insertion space 116. Since the shielding cover 1 has a plurality of housings 11, the shielding cover 1 has a plurality of insertion spaces 116 and a plurality of the windows 116b corresponding to the plurality of insertion spaces 116 respectively. It should be noted that in a variant embodiment, the shielding cover 1 can also be integrally formed but separated into a plurality of insertion spaces 116 by a plurality of partition walls (not shown). Each socket connector 200 is disposed in the rear section of the insertion space 116 of the corresponding housing 11. The socket connector 200 has an insulating housing 201 and a plurality of terminals 202. The housing 201 has two insertion slots 201a facing the front-end opening 116a and used for docking with the pluggable module 300. The plurality of terminals 202 are located in the two insertion slots 201a and are electrically and mechanically connected to the aforementioned circuit board. Specifically, the socket connector 200 is mechanically and electrically disposed on the circuit board and covered by the housing 11 of the shielding cover 1 through the bottom opening 116c, so that the socket connector 200 is disposed in the insertion space 116, but not limited thereto. For example, each terminal 202 of the socket connector 200 does not have to be connected to the circuit board, and each terminal 202 can also be connected to a cable.

[0076] The two insertion slots 201a of the socket connector 200 are arranged side by side at intervals along the up-and-down direction D2. A partition member 117 (only a grounding gasket 117a of the partition member 117 is shown in the figure) is provided in the insertion space 116 of the cover body 11 of the shielding cover 1. The partition member 117 divides the insertion space 116 into a first module channel 116d and a second module channel 116e arranged along the up-and-down direction D2. The first module channel 116d and the second module channel 116e respectively correspond to the two insertion slots 201a of the socket connector 200. When the pluggable module 300 is inserted into the first module channel 116d and the second module channel 116e through the front-end opening 116a, the circuit board 302 provided at the end of the docking portion 301 of the pluggable module 300 can be inserted into the corresponding insertion slot 201a to be docked with the socket connector 200. Among them, the upper first module channel 116d communicates with the window 116b. It should be noted that in other embodiments, the cover body 11 of the shielding cover 1 may not be provided with the partition member 117, and this is not limited to the first embodiment.

[0077] The liquid cooling plate 2 is used for the cooling liquid to circulate internally. The liquid cooling plate 2 includes a housing 21 for the cooling liquid to flow internally. The cooling liquid can be, for example, water or other cooling liquids. The housing 21 is made of, for example, metal (such as copper, aluminum) and also has an inlet 211 and an outlet 212 located at the rear end for the cooling liquid to flow in or out, and a flow channel (not shown in the figure) located inside and communicating between the inlet 211 and the outlet 212. The liquid cooling plate 2 can be used in combination with other components of a liquid cooling system (not shown in the figure) so that the cooling liquid can absorb heat from the liquid cooling plate 2 and then dissipate the heat through the above-mentioned components after leaving. The above-mentioned components include, for example, fluid conduits, radiators, cooling fans, pumps, water tanks, etc. The above-mentioned components can be provided outside the shielding cover 1. The liquid cooling plate 2 can be fixed, for example, on the frame (not shown in the figure) of a device, so that the liquid cooling plate 2 is fixedly attached to the shielding cover 1 relative to the shielding cover 1 without movement.

[0078] Refer to Figure 2 and Figures 4 to 7, a plurality of thermal coupling modules 3 respectively correspond to the insertion spaces 116 of a plurality of housing bodies 11 of the shielding cover 1, and the plurality of thermal coupling modules 3 are connected to the same liquid cooling plate 2. Each thermal coupling module 3 includes a thermal coupling base 31, a thermal interface material 32 (Thermal Interface Material, TIM), a plurality of connecting bolts 33, and a plurality of elastic members 34. The thermal coupling base 31 is made of metal (such as copper or aluminum) for example, and is generally plate-shaped in this first embodiment. The thermal coupling base 31 has a thermal coupling portion 311 that protrudes downward and extends into the corresponding insertion space 116 through the corresponding opening 116b into the first module channel 116d. The thermal interface material 32 can be selected from a combination of materials with high thermal conductivity, high flexibility, compressibility, elasticity, insulation, wear resistance, etc. for example, and is generally sheet-shaped in this first embodiment. The thermal interface material 32 is compressible and clamped between the liquid cooling plate 2 and the thermal coupling base 31.

[0079] A plurality of connecting bolts 33 are arranged between the liquid cooling plate 2 and the thermal coupling base 31, so that the thermal coupling base 31 can be connected to the liquid cooling plate 2 by the plurality of connecting bolts 33 away from or close to the liquid cooling plate 2 relative to the liquid cooling plate 2, and the thermal interface material 32 is pre-pressed. Specifically, in this first embodiment, the housing 21 of the liquid cooling plate 2 is formed with a plurality of first connection holes 213, the thermal coupling base 31 is formed with a plurality of second connection holes 312, each connecting bolt 33 penetrates through the corresponding first connection hole 213 and the corresponding second connection hole 312, and each connecting bolt 33 has a first limiting block 331 and a second limiting block 332. The first limiting block 331 and the second limiting block 332 respectively abut against the periphery of the corresponding first connection hole 213 of the liquid cooling plate 2 and the periphery of the corresponding second connection hole 312 of the thermal coupling base 31 to limit the maximum distance between the thermal coupling base 3 and the liquid cooling plate 2 and allow the thermal coupling base 3 to move in the direction towards the liquid cooling plate 2, and the thermal interface material 32 is pre-pressed. That is to say, the connecting bolt 33 limits the distance between the thermal coupling base 31 and the liquid cooling plate 2, and makes the distance always less than the thickness of the thermal interface material 32. In addition, the cross-section of the bottom of the second limiting block 332 is semicircular and each connecting bolt 33 is formed with a slit 333 extending upward from the bottom of the second limiting block 332, so that the second limiting block 332 can easily pass through the second connection hole 312 downward.

[0080] A plurality of elastic members 34 are disposed between the liquid cooling plate 2 and the thermal coupling base 31, and are used to drive the thermal coupling base 31 to move away from the liquid cooling plate 2. In this first embodiment, the plurality of elastic members 34 are coil springs, and the plurality of elastic members 34 are sleeved on the corresponding connecting bolts 33. However, the plurality of elastic members 34 can also be other types of elastic elements, such as spring sheets, and their installation positions do not necessarily need to be sleeved on the connecting bolts 33, for example, clamped between the liquid cooling plate 2 and the thermal coupling base 31.

[0081] Refer to Figures 1 to 2 and Figures 6 to 7 , when the pluggable module 300 is inserted into the first module channel 116d of the insertion space 116 of the housing 11, the thermal coupling base 31 is pushed by the pluggable module 300 to move relatively towards the liquid cooling plate 2. At this time, the thermal coupling base 31 squeezes the plurality of elastic members 34 and the thermal interface material 32. After the pluggable module 300 is pulled out, the thermal coupling base 31 and the thermal interface material 32 can be elastically reset away from the liquid cooling plate 2 through the elastic restoring force of the plurality of elastic members 34. Further, the thermal interface material 32 can also have elasticity at the same time to jointly provide the elastic force for resetting the thermal coupling base 31 with the plurality of elastic members 34. The liquid cooling plate 2 in the connector assembly 100 of the present invention has better heat dissipation performance than a general radiator, and the thermal interface material 32 is clamped between the liquid cooling plate 2 and the thermal coupling base 31 under pre-pressure through the connecting bolts 33, so that the thermal interface material 32 can be completely in contact between the liquid cooling plate 2 and the thermal coupling base 31, thereby increasing the heat transfer effect of the thermal interface material 32 and improving the heat dissipation and cooling effect of the liquid cooling plate 2. In addition, since the thermal interface material 32 is pre-pressed, it is not necessary to increase its deformation stroke amount through the thickness of the thermal interface material 32 to ensure complete contact between components. Therefore, a thinner thermal interface material 32 can be selected to reduce the thermal resistance of the thermal interface material 32 itself, so as to exert a greater heat transfer effect and improve the heat dissipation and cooling effect of the liquid cooling plate 2. Furthermore, through the connecting bolts 33 and the elastic members 34, the compressibility and elasticity of each thermal coupling module 3 can be improved, and through the independent operation of each thermal coupling module 3, the tolerances of different pluggable modules 300 inserted into the shielding cover 1 can be absorbed, so that each pluggable module 300 can have good contact with the corresponding thermal coupling module 3 respectively, thereby further improving the heat dissipation efficiency.

[0082] Refer to Figures 8 to 10, the difference between a second embodiment of the connector assembly of the present invention and the first embodiment is that, in this second embodiment, the connector assembly further includes a plurality of elastic fasteners 4 provided on a plurality of cover bodies 11 of the shielding cover 1. The plurality of elastic fasteners 4 are fastened to the corresponding cover body 11 of the shielding cover 1 and pressed against the corresponding heat coupling base 31 in such a manner that two elastic fasteners 4 correspond to one cover body 11 and one heat coupling base 31. It should be noted that, in a variant embodiment, the two elastic fasteners 4 corresponding to the same cover body 11 and the same heat coupling base 31 may not be of a two-piece structure but a single-piece structure integrally formed. In another variant embodiment, there may be more than three corresponding to the same cover body 11 and the same heat coupling base 31. In other words, the elastic fasteners 4 are pressed against the heat coupling base 31 in such a manner that at least one elastic fastener 4 corresponds to one heat coupling base 31.

[0083] Specifically, in this second embodiment, the two elastic fasteners 4 corresponding to the same cover body 11 and the same heat coupling base 31 are spaced side by side in the front-rear direction D1. Each elastic fastener 4 has an elastic pressing portion 41 extending in the left-right direction D3 and pressing against the corresponding heat coupling base 31 in a direction away from the liquid cooling plate 2, and a fastening portion 42 extending downward from both ends of the elastic pressing portion 41 in the left-right direction D3 and used for fastening to the side wall 113 of the corresponding cover body 11 of the shielding cover 1 (see Figure 1 ). Two accommodating grooves 313 corresponding to accommodating the elastic pressing portions 41 are formed at the top surface of each heat coupling base 31. The two accommodating grooves 313 extend in the left-right direction D3 and are spaced side by side in the front-rear direction D1. By means of the plurality of elastic fasteners 4, the elastic force for resetting the plurality of heat coupling bases 31 in a direction away from the liquid cooling plate 2 can be increased.

[0084] Referring to Figures 11 to 12 , the difference between a third embodiment of the connector assembly of the present invention and the second embodiment is that, in this third embodiment, the number of elastic fasteners 4 provided on the cover body 11 of the shielding cover 1 is only one. The elastic fastener 4 has a plurality of elastic pressing portions 41 pressing against a plurality of heat coupling bases 31 in a direction away from the liquid cooling plate 2 (see Figure 1 ), a plurality of connecting portions 43 connected between the plurality of elastic pressing portions 41 and used for being arranged on the top of the shielding cover 1, and two fastening portions 44 extending downward from the outer sides of the two elastic pressing portions 41 located on both sides in the left-right direction D3 and used for fastening to the outer side walls 113 of the shielding cover 1 (see Figure 1 ).

[0085] However, the above are only embodiments of the present invention, and the scope of implementation of the present invention cannot be limited thereby.
