Description

Connector Assemblies

The present invention relates to a connector assembly, and more particularly to a connector assembly with a liquid cooling plate.

U.S. Patent Publication No. US7,625,223 discloses a socket assembly comprising a guide frame, a heat sink and a conductive gasket. The guide frame comprises a top wall and defines an internal chamber configured to accommodate a mating connector. The top wall defines an opening communicating with the internal chamber. The heat sink is held in the internal chamber so that when the mating connector is inserted into the internal 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 guide frame and the heat sink. The heat sink comprises a coupling portion, and when the mating connector is inserted into the internal chamber, the coupling portion provides a heat conductive path for the mating connector. The conductive gasket is configured to be compressed between the guide frame and the heat sink so that the conductive gasket provides a conductive path between the heat sink and the guide frame. However, the heat sink disclosed in the prior art is generally a metal heat sink with heat sink fins, and its principle is to remove heat through the air flow passing through the heat sink fins. In connector assemblies with higher transmission speeds and greater heat generation, its heat dissipation performance is slightly insufficient.

Chinese invention patent publication number CN110139534A (corresponding to US invention patent publication number US2019/0246523A1) discloses a cooling device, which includes a manifold and a plurality of bases. The manifold includes a shell surrounding an inner cavity, and the inner cavity is used to contain a cooling liquid and circulate the cooling liquid. Each base is individually and flexibly coupled to the shell of the manifold through a bellows for sealing and in an annular shape. Each base is configured to extend outward from the bottom surface of the shell of the manifold when there is fluid pressure in the inner cavity. However, the bellows of the prior art only provide a flexible connection between the base and the manifold. The base needs to have sufficient force to extend outward from the bottom surface of the manifold shell only when there is fluid pressure in the inner cavity of the manifold. First, the bellows, as a connection seal between the base and the manifold, is not only complex in structure but also difficult to manufacture. Secondly, since the base can only extend outward by the fluid pressure, when the fluid pressure is insufficient or unstable, it is easy to cause the base to not protrude outward enough relative to the manifold, resulting in insufficient pressure on the base to contact the electrical module or even failure to contact the electrical module, thereby reducing the heat dissipation efficiency. Furthermore, when multiple electrical modules need to contact the bases on the manifold at the same time, if the outward protrusion 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 the electrical modules to be unable to contact the bases on the manifold at the same time due to tolerance problems of the electrical modules.

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

Therefore, in some embodiments of the connector assembly of the present invention, it includes a shielding cover, a liquid cooling plate, and a thermal coupling module. The shielding cover has an insertion space and a window connected to the insertion space. The liquid cooling plate is used for cooling liquid to circulate inside. The thermal coupling module includes a thermal coupling base and a thermally conductive interface material. The thermal coupling base has a thermal coupling portion extending into the insertion space through the window. The thermally conductive interface material can be compressed and sandwiched between the liquid cooling plate and the thermal coupling base. The thermal coupling base can be connected to the liquid cooling plate far away from or close to the liquid cooling plate.

In some embodiments, the thermal coupling module further includes an elastic member disposed between the liquid cooling plate and the thermal coupling base. When the thermal coupling base moves relatively toward the liquid cooling plate, the thermal coupling base squeezes the elastic member and the thermally conductive interface material. The thermal coupling base and the thermally conductive interface material can be elastically reset in a direction away from the liquid cooling plate by the elastic restoring force of the elastic member.

In some embodiments, the thermal coupling module further includes a connecting bolt disposed between the liquid cooling plate and the thermal coupling base, wherein the connecting bolt pre-stresses the thermally conductive interface material.

In some implementations, the elastic member is a coil spring, and the elastic member is sleeved on the corresponding connecting pin.

In some implementations, an elastic clip is further included on the shielding cover, the elastic clip is pressed against the thermal coupling base, and the elastic clip has an elastic pressure portion that presses against the corresponding thermal coupling base in a direction away from the liquid cooling plate.

Therefore, in some embodiments of the connector assembly of the present invention, it includes a shielding cover, a liquid cooling plate, and a plurality of thermal coupling modules. The shielding cover has a plurality of insertion spaces and a plurality of windows respectively corresponding to and connected to the plurality of insertion spaces. The liquid cooling plate is used for cooling liquid to circulate inside. The plurality of thermal coupling modules respectively correspond to the plurality of insertion spaces and are independently connected to the same liquid cooling plate. Each of the thermal coupling modules includes a thermal coupling base and a thermally conductive interface material. The thermal coupling base has a thermal coupling portion extending into the insertion space through the window. The thermally conductive interface material can be compressed and sandwiched between the liquid cooling plate and the thermal coupling base. The thermal coupling base can be connected to the liquid cooling plate far away from or close to the liquid cooling plate.

In some embodiments, the thermal coupling module further includes an elastic member disposed between the liquid cooling plate and the thermal coupling base. When the thermal coupling base moves relatively toward the liquid cooling plate, the thermal coupling base squeezes the elastic member and the thermally conductive interface material. The thermal coupling base and the thermally conductive interface material can be elastically reset in a direction away from the liquid cooling plate by the elastic restoring force of the elastic member.

In some embodiments, the thermal coupling module further includes a connecting bolt disposed between the liquid cooling plate and the thermal coupling base, wherein the connecting bolt pre-stresses the thermally conductive interface material.

In some implementations, the elastic member is a coil spring, and the elastic member is sleeved on the corresponding connecting pin.

In some implementations, a plurality of elastic clips are disposed on the shielding cover, and the elastic clips are pressed against the thermal coupling base in a manner that one elastic clip corresponds to one thermal coupling base, and the elastic clips have an elastic pressing portion that presses against the corresponding thermal coupling base in a direction away from the liquid cooling plate.

In some implementations, an elastic clip is further provided on the shielding cover, wherein the elastic clip has a plurality of elastic pressure-applying portions that press against the corresponding plurality of thermal coupling bases in a direction away from the liquid cooling plate.

The liquid cooling plate in the connector assembly of the present invention has better heat dissipation performance than a general heat sink, and the thermally conductive interface material is pre-stressed and sandwiched between the liquid cooling plate and the thermal coupling base through the connecting bolt, so that the thermally conductive interface material can completely contact between the liquid cooling plate and the thermally coupled base, thereby increasing the heat transfer effect of the thermally conductive interface material and improving the heat dissipation and cooling effect of the liquid cooling plate. In addition, since the thermally conductive interface material is pre-stressed, it is not necessary to increase the deformation stroke of the thermally conductive interface material by the thickness of the thermally conductive interface material to ensure complete contact between the components, thereby enabling the use of thinner thermally conductive interface materials to reduce the thermal resistance of the thermally conductive interface materials, thereby exerting a greater heat transfer effect and improving the heat dissipation and cooling effect of the liquid cooling plate. Furthermore, the compressibility and elasticity of the thermal coupling module can be improved by the connecting pins and the elastic components, and the tolerances of different pluggable modules inserted into the shielding cover can be absorbed by the independent operation of each thermal coupling module, so that each pluggable module can have good contact with the corresponding thermal coupling module, thereby further improving the heat dissipation performance.

Before the present invention is described in detail, it should be noted that similar components are represented by the same reference numerals in the following description.

Referring to FIGS. 1 to 4 , a first embodiment of a connector assembly 100 of the present invention is suitable for covering a plurality of socket connectors 200 and for plugging with a pluggable module 300. The connector assembly 100 comprises a shielding cover 1, a liquid cooling plate 2, and a plurality of thermal coupling modules 3. It should be noted that the shielding cover 1 has a plurality of cover bodies 11 assembled side by side in this embodiment, and each cover body 11 corresponds to one of the socket connectors 200. However, in other embodiments, the shielding cover 1 may have only one cover body 11, and the number of the socket connectors 200 may also be adjusted accordingly as required.

The shielding cover 1 can be made of metal, for example. The shielding cover 1 has a cover body 11 extending along a front-to-back direction D1 and having a top wall 111, a bottom wall 112 spaced opposite to the top wall 111 along a vertical direction D2, two side walls 113 spaced opposite to each other along a left-right direction D3 and connected to the top wall 111 and the bottom wall 112 on both sides, and a plurality of pins 115 extending downward from the side walls 113 and suitable for being fixed on a circuit board (not shown) and/or connected to a grounding track. The shielding cover 1 also 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 opening 116a located at the front end and connected to the insertion space 116, a window 116b formed on the top wall 111 and connected to the insertion space 116, and a bottom opening 116c located at the rear side of the bottom wall 112 and connected to the insertion space 116. Because the shielding cover 1 has a plurality of shielding bodies 11, the shielding cover 1 has a plurality of insertion spaces 116 and a plurality of windows 116b corresponding to the insertion spaces 116. It should be noted that in a variant embodiment, the shielding cover 1 can also be formed as an integral structure but a plurality of insertion spaces 116 are separated by a plurality of partition walls (not shown). Each socket connector 200 is disposed at 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 opening 116a and used to connect with the pluggable module 300. The terminals 202 are located in the insertion slots 201a and are electrically and mechanically connected to the front opening 116a. Specifically, the socket connector 200 is mechanically and electrically disposed on the circuit board, and is covered by the cover body 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 is not limited thereto. For example, each terminal 202 of the socket connector 200 may not necessarily be connected to the circuit board, and each terminal 202 may also be connected to a cable.

The two insertion slots 201a of the socket connector 200 are arranged side by side with a distance from each other along the vertical direction D2. The insertion space 116 of the cover body 11 of the shielding cover 1 is provided with a partition member 117 (only a grounding pad 117a of the partition member 117 is shown in the figure). The partition member 117 divides the insertion space 116 into a first module channel 116d and a second module channel 116e arranged along the vertical direction D2. The module channel 116d and the second module channel 116e respectively correspond to the two plug-in 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 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 plug-in slot 201a to dock with the socket connector 200. The first module channel 116d located at the top is connected to the window 116b. It should be noted that in other embodiments, the housing 11 of the shielding cover 1 may not be provided with the partition member 117, which is not limited to the first embodiment.

The liquid cooling plate 2 is used for circulating cooling liquid inside, and the liquid cooling plate 2 includes a shell 21 for cooling liquid to flow inside. The cooling liquid can be water or other cooling liquid, for example. The shell 21 is made of metal (such as copper, aluminum) and has an inlet 211 and an outlet 212 at the rear end for cooling liquid to flow in or out, and a flow channel (not shown) located inside and connected between the inlet 211 and the outlet 212. The liquid cooling plate 2 can be used in conjunction with other components of a liquid cooling heat dissipation system (not shown) so that the cooling liquid can dissipate heat through the components after absorbing heat from the liquid cooling plate 2 and leaving the liquid cooling plate 2. For example, the components include a fluid duct, a heat sink, a heat dissipation fan, a pump, a water tank, etc., and the above components can be arranged outside the shielding cover 1. For example, the liquid cooling plate 2 can be fixed on a rack of a device (not shown) so that the liquid cooling plate 2 is fixed on the shielding cover 1 without moving relative to the shielding cover 1.

Referring to FIG. 2 and FIG. 4 to FIG. 7 , the thermal coupling modules 3 correspond to the insertion spaces 116 of the housings 11 of the shielding cover 1, respectively, and the 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 (TIM), a plurality of connecting pins 33, and a plurality of elastic members 34. The thermal coupling base 31 is made of metal (such as copper, aluminum) for example, and is generally plate-shaped in the first embodiment. The thermal coupling base 31 has a thermal coupling portion 311 that protrudes downward and extends into the first module channel 116d of the corresponding insertion space 116 through the corresponding window 116b. The thermally conductive interface material 32 can be selected from a combination of materials having high thermal conductivity, high flexibility, compressibility, elasticity, insulation, wear resistance, etc., and is generally in sheet form in the first embodiment. The thermally conductive interface material 32 can be compressed and sandwiched between the liquid cooling plate 2 and the thermal coupling base 31.

The connecting bolts 33 are disposed 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 via the connecting bolts 33 at a distance from or close to the liquid cooling plate 2, and the thermally conductive interface material 32 is pre-stressed. Specifically, in the first embodiment, the shell 21 of the liquid cooling plate 2 is formed with a plurality of first connecting holes 213, and the thermal coupling base 31 is formed with a plurality of second connecting holes 312. Each connecting bolt 33 extends through the corresponding first connecting hole 213 and the corresponding second connecting hole 312, and each connecting bolt 33 has a first stop block 331 and a second stop block 332. The first stop block The connecting bolt 331 and the second limiting block 332 are respectively used to abut against the surrounding of the corresponding first connecting hole 213 of the liquid cooling plate 2 and the surrounding of the corresponding second connecting hole 312 of the thermal coupling base 31, so as to limit the maximum spacing distance between the thermal coupling base 3 and the liquid cooling plate 2 and allow the thermal coupling base 3 to move toward the liquid cooling plate 2, and pre-stress the thermal interface material 32. In other words, the connecting bolt 33 limits the spacing distance between the thermal coupling base 31 and the liquid cooling plate 2, and makes the spacing distance always smaller 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 connecting hole 312 downward.

The 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 the first embodiment, the elastic members 34 are coil springs, and the elastic members 34 are sleeved on the corresponding connecting bolts 33, but the elastic members 34 can also be other types of elastic elements, such as spring sheets, and their arrangement positions do not need to be sleeved on the connecting bolts 33, for example, they can be sandwiched between the liquid cooling plate 2 and the thermal coupling base 31.

Referring to FIGS. 1 to 2 and 6 to 7 , when the pluggable module 300 is inserted into the first module channel 116d of the insertion space 116 of the cover body 11 , the thermal coupling base 31 is pushed by the pluggable module 300 to move relatively toward the liquid cooling plate 2 . At this time, the thermal coupling base 31 squeezes the elastic components 34 and the thermally conductive interface material 32 . When the pluggable module 300 is pulled out, the thermal coupling base 31 and the thermally conductive interface material 32 can be elastically reset in a direction away from the liquid cooling plate 2 by the elastic restoring force of the elastic components 34 . Furthermore, the thermally conductive interface material 32 may also be elastic, so as to provide elastic force together with the elastic components 34 to reset the thermal coupling base 31. The liquid cooling plate 2 in the connector assembly 100 of the present invention has better heat dissipation performance than a general heat sink, and the thermally conductive interface material 32 is pre-stressed and sandwiched between the liquid cooling plate 2 and the thermal coupling base 31 through the connecting bolt 33, so that the thermally conductive interface material 32 can be completely in contact between the liquid cooling plate 2 and the thermal coupling base 31, so as to increase the heat transfer effect of the thermally conductive interface material 32 and enhance the heat dissipation cooling effect of the liquid cooling plate 2. In addition, since the thermally conductive interface material 32 is pre-stressed, it is not necessary to increase the deformation stroke of the thermally conductive interface material 32 by increasing its thickness to ensure complete contact between components. Therefore, a thinner thermally conductive interface material 32 can be selected to reduce the thermal resistance of the thermally conductive interface material 32 itself, so as to exert a greater heat transfer effect and enhance the heat dissipation cooling effect of the liquid cooling plate 2. Furthermore, the compressibility and elasticity of each thermal coupling module 3 can be enhanced by the connecting bolt 33 and the elastic member 34, and the tolerance of different pluggable modules 300 inserted into the shielding cover 1 can be absorbed by the independent operation of each thermal coupling module 3, so that each pluggable module 300 can have good contact with the corresponding thermal coupling module 3, thereby further enhancing the heat dissipation performance.

Referring to Figures 8 to 10, a second embodiment of the connector assembly of the present invention is different from the first embodiment in that, in the second embodiment, the connector assembly further includes a plurality of elastic fasteners 4 disposed on the cover bodies 11 of the shielding cover 1, and the elastic fasteners 4 are fastened to the cover bodies 11 of the corresponding shielding cover 1 and pressed against the corresponding thermal coupling base 31 in a manner that two elastic fasteners 4 correspond to one cover body 11 and one thermal 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 thermal coupling base 31 may not be a two-piece type but a single-piece type formed by an integral structure, and in another variant embodiment, there may be more than three elastic fasteners 4 corresponding to the same cover body 11 and the same thermal coupling base 31. In other words, the elastic fasteners 4 are pressed against the thermal coupling base 31 in a manner that at least one elastic fastener 4 corresponds to one thermal coupling base 31.

In detail, in the second embodiment, two elastic fasteners 4 corresponding to the same cover body 11 and the same thermal coupling base 31 are spaced apart and arranged side by side in the front-to-back direction D1, and each elastic fastener 4 has an elastic pressure-applying portion 41 extending along the left-right direction D3 and pressing against the corresponding thermal coupling base 31 in the direction away from the liquid cooling plate 2, and a buckling portion 42 extending downward from both ends of the elastic pressure-applying portion 41 in the left-right direction D3 and used to buckle to the side wall 113 (see Figure 1) of the cover body 11 of the corresponding shielding cover 1. Two receiving grooves 313 corresponding to the elastic pressure applying portion 41 are formed on the top surface of each thermal coupling base 31. The two receiving grooves 313 extend along the left-right direction D3 and are spaced and arranged side by side along the front-back direction D1. The elastic buckles 4 can increase the elastic force that causes the thermal coupling bases 31 to return to the direction away from the liquid cooling plate 2.

Referring to Figures 11 and 12, a third embodiment of the connector assembly of the present invention is different from the second embodiment in that in the third embodiment, the number of the elastic fastener 4 arranged on the cover body 11 of the shielding cover 1 is only one, and the elastic fastener 4 has a plurality of elastic pressure-applying parts 41 that press against the thermal coupling bases 31 in a direction away from the liquid cooling plate 2 (see Figure 1), a plurality of connecting parts 43 connected between the elastic pressure-applying parts 41 and used to be arranged on the top of the shielding cover 1, and two fastening parts 44 that extend downward from the outer sides of the elastic pressure-applying parts 41 located on the two sides in the left-right direction D3 and are used to be fastened to the two side walls 113 (see Figure 1) located on the outer sides of the shielding cover 1.

However, the above is only an example of the implementation of the present invention, and it cannot be used to limit the scope of the implementation of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still within the scope of the patent of the present invention.
