The first lower side plate 22 and the second lower side plate 23 are vertically connected to the bottom plate 21 to form a rectangular shell structure with an opening upward. The rectangular shell structure formed by the second fastening member 2 is substantially the same size as the rectangular shell structure formed by the first fastening member 1.

[0055] like Figure 1 and Figure 2 As shown, the first upper side plate 12 and the second upper side plate 13 are both provided with a first buckle portion 16. Figure 1 As shown, the first lower side plate 22 and the second lower side plate 23 are both provided with a first snap-fitting portion 24. The first snap-fitting member 1 and the second snap-fitting member 2 are connected by snapping the first snap-fitting portion 16 and the first snap-fitting portion 24. There are a plurality of first snap-fitting portions 16 and a plurality of first snap-fitting portions 24, respectively. The specific number of the first snap-fitting portions 16 and the first snap-fitting portions 24 is specifically set according to actual needs, so as to achieve the purpose of being easy to install and disassemble. In order to facilitate installation and disassembly, a plurality of first snap-fitting portions 16 and a plurality of first snap-fitting portions 24 are arranged at intervals along the length direction of the side plate to improve the stability of the connection.

[0057] In this embodiment, the first snap-fit ​​portion 16 is a snap-fit ​​hole, which may be triangular, rectangular, polygonal or circular. The first snap-fit ​​portion 24 is a convex block protruding toward the outer side of the corresponding side plate, which may be triangular, rectangular, polygonal or circular. The first snap-fit ​​portion 24 is snap-fitted with the first snap-fit ​​portion 16, and the first snap-fit ​​portion 24 is located in the snap-fit ​​hole of the first snap-fit ​​portion 16. When the first fastening member 1 and the second fastening member 2 are connected, the first upper side plate 12 is located on the outer side of the first lower side plate 22, and the second upper side plate 13 is located on the outer side of the second lower side plate 23, thereby improving the stability of the connection and preventing the first snap-fit ​​portion 24 and the first snap-fit ​​portion 16 from being disengaged.

[0058] In another embodiment, the first buckle portion 16 can be set as a protrusion, the first locking portion 24 can be set as a locking hole, the first upper side plate 12 is located on the inner side of the first lower side plate 22, and the second upper side plate 13 is located on the inner side of the second lower side plate 23.

[0059] In another embodiment, one of the first buckle portion 16 and the first engaging portion 24 is configured as a locking hole, and the other is configured as a hanging ear or a hook.

[0060] like Figure 1 and Figure 2 As shown, the third upper side plate 14 and the fourth upper side plate 15 are both provided with a second buckle portion 17. The second buckle portion 17 is used to buckle and connect with the shielding cage 3, so as to fix the heat sink buckle structure in the shielding cage 3, so that the positions of the heat sink 4 in the heat sink buckle structure and the optical module 5 in the shielding cage 3 are relatively fixed, so as to achieve good heat dissipation and temperature reduction.

[0061] There are multiple second buckle parts 17, and the specific number of the second buckle parts 17 is specifically set according to actual needs to achieve easy installation and easy disassembly. In order to facilitate installation and disassembly, multiple second buckle parts 17 are spaced along the length direction of the side plate to improve the stability of the connection.

[0062] In this embodiment, the second buckle portion 17 is a buckle hole, which can be triangular, rectangular, polygonal or circular. Correspondingly, a protrusion or a hanging ear is provided on the shielding cage 3, which is connected with the buckle hole. The protrusion can be triangular, rectangular, polygonal or circular.

That is, the first upper side plate 12 is arranged between two adjacent third upper side plates 14, and the second upper side plate 13 is arranged between two adjacent fourth upper side plates 15, thereby dispersing the connection points between the radiator buckle structure and the shielding cage 3, and improving the stability of the connection. Among them, there may be a gap between the first upper side plate 12 and the third upper side plate 14, or it may be an integrally formed structure (i.e., without a gap).

[0065] In one embodiment, the first upper side plate 12 and the first lower side plate 22 are one, the second upper side plate 13 and the second lower side plate 23 are three, and the third upper side plate 14 and the fourth upper side plate 15 are two.

[0066] In the present application, a plurality refers to two or more. The lengths of the third upper side plate 14 and the fourth upper side plate 15 can be set according to actual needs, and can be greater than or equal to the lengths of the first upper side plate 12 and the second upper side plate 13 .

[0067] like Figure 1 and Figure 2 As shown, the first fastening member 1 further includes a fifth upper side plate 18 and a sixth upper side plate 19 located on both sides of the top plate 11 in the width direction, and the fifth upper side plate 18 and the sixth upper side plate 19 are both provided with a first buckle portion 16. Figure 1 and Figure 2 As shown, the second fastening member 2 also includes a third lower side plate 25 and a fourth lower side plate 26 located on both sides of the bottom plate 21 in the width direction, and the third lower side plate 25 and the fourth lower side plate 26 are both provided with a first snap-fitting portion 24. The structure of the first snap-fitting portion 16 and the first snap-fitting portion 24 is consistent with that of the above-mentioned embodiment and will not be described in detail. Among them, the fifth upper side plate 18 is in the same position as the third lower side plate 25 in the length direction, the sixth upper side plate 19 is in the same position as the fourth lower side plate 26 in the length direction, and the number of the first snap-fitting portions 16 and the first snap-fitting portions 24 are the same and their positions are arranged one-to-one. As shown in FIG. Figure 4 and Figure 5 As shown, the fifth upper side plate 18 and the third lower side plate 25 are respectively arranged in the middle position of the top plate 11 and the bottom plate 21. After the two are connected up and down, the connecting blocks and joints on both sides of the radiator 4 can extend from both sides and be connected to the liquid storage device through pipelines.

[0068] The first upper side plate 12, the second upper side plate 13, the third upper side plate 14, the fourth upper side plate 15, the fifth upper side plate 18 and the sixth upper side plate 19 are vertically connected to the top plate 11, and together form a rectangular shell structure with an opening downward. The first lower side plate 22, the second lower side plate 23, the third lower side plate 25 and the fourth lower side plate 26 are vertically connected to the bottom plate 21, and together form a rectangular shell structure with an opening upward. The fifth upper side plate 18 and the third lower side plate 25, and the sixth upper side plate 19 and the fourth lower side plate 26 are respectively connected by the corresponding first snap-fitting part 16 and the first snap-fitting part 24. The first snap-fitting part 1 and the second snap-fitting part 2 are connected to form a accommodating space that is limited left and right, up and down, and front and back, and the radiator is arranged in it to prevent shaking.

[0069] like Figure 1 and Figure 2 As shown, the first upper side plate 12, the second upper side plate 13, the third upper side plate 14 and the fourth upper side plate 15 are all provided with guide plates 10, which extend in a direction away from the top plate 11 and are inclined toward the outer side of the corresponding side plate. That is, the guide plate 10 on the first upper side plate 12 is inclined toward the outer side of the first upper side plate 12, the guide plate 10 on the second upper side plate 13 is inclined toward the outer side of the second upper side plate 13, the guide plate 10 on the third upper side plate 14 is inclined toward the outer side of the third upper side plate 14, and the guide plate 10 on the fourth upper side plate 15 is inclined toward the outer side of the fourth upper side plate 15. The guide plate 10 can facilitate the fixed installation of the first fastening member 1 on the second fastening member 2 and the shielding cage 3. When the first fastening member 1 and the second fastening member 2 are installed, there is no need for precise alignment, and the installation can be quickly achieved with the guidance of the guide plate 10; when the radiator fastening structure as a whole is installed with the shielding cage 3, the installation can be quickly achieved with the guidance of the guide plate 10. The guide plate 10 can reduce the difficulty of installing the radiator snap-fit ​​structure and improve the installation efficiency.

[0070] The top surface of the first fastening member 1 is provided with a plurality of elastic pressing pieces 112 extending toward the inner side of the top surface. After the first fastening member 1 and the second fastening member 2 are connected, the elastic pressing pieces 112 are used to press the upper surface of the heat sink 4 to prevent the heat sink 4 from moving in the accommodation space.

[0071] In this embodiment, if Figure 1 and Figure 2As shown, the top plate 11 of the first fastening member 1 is provided with a first heat dissipation hole 111. The first heat dissipation hole 111 is used to increase the heat exchange efficiency between the radiator 4 located in the accommodating space and the outside air, and improve the cooling efficiency of the radiator 4. The first heat dissipation hole 111 is preferably but not limited to a rectangular hole, and the first heat dissipation hole 111 can also be selected to be circular, triangular or polygonal. In this embodiment, there are multiple first heat dissipation holes 111, and the multiple first heat dissipation holes 111 are respectively arranged at intervals along the length direction and the width direction of the top plate 11, that is, they are arranged in a matrix form. In addition, the first heat dissipation holes 111 can also be used as lightweight holes to reduce the weight of the first fastening member 1.

[0072] Furthermore, an elastic pressing sheet 112 is provided on one side of the first heat dissipation hole 111. The elastic pressing sheet 112 extends into the accommodation space and is used to press the upper surface of the heat sink 4 to prevent the heat sink 4 from moving in the accommodation space. The elastic pressing sheet 112 can adjust the tightness between the heat sink 4 and the heating device (such as the optical module 5) by pressing the heat sink 4, and can ensure that the heat sink 4 and the heating device (such as the optical module 5) are tightly fitted.

[0073] In this embodiment, a plurality of first heat dissipation holes 111 are arranged in a matrix form on the top plate 11, so that a plurality of elastic pressing plates 112 are also arranged in a matrix form. The plurality of elastic pressing plates 112 are arranged in a matrix form, and a balanced pressure can be applied to different positions of the upper surface of the heat sink 4, so that the heat sink 4 can be pressed against all the optical modules 5, thereby ensuring that the heat dissipation of each optical module 5 has good uniformity, improving the cooling effect of the entire optical module system, and avoiding the influence of the optical module system accuracy due to local (individual optical module) overheating. Since the heat sink is fixed in the heat sink buckle structure, when a certain optical module 5 is pulled out, the floating and heat dissipation effects on the remaining optical modules 5 are relatively weak.

[0074] Preferably, the elastic pressing piece 112 and the top plate 11 are integrally formed, that is, when the first heat dissipation hole 111 is cut or punched on the top plate 11, the cut or punched portion of the material is not completely broken from the top plate 11, and the portion of the material forms the elastic pressing piece 112 extending toward one side of the accommodation space. The elastic pressing piece 112 and the top plate 11 are integrally formed, which can reduce the assembly steps, does not require additional welding or fasteners for connection, and can also improve strength and stability and reduce costs.

[0075] like Figure 1 As shown, the bottom plate 21 is provided with a second heat dissipation hole 211. Figure 5As shown, the second heat dissipation hole 211 is used for allowing the radiator 4 to at least partially extend, so that the extended portion of the radiator 4 can be limitedly connected with the shielding cage 3. In addition, the second heat dissipation hole 211 can also be used to increase the heat exchange efficiency between the radiator 4 and the outside air in the accommodating space, and improve the cooling efficiency of the radiator 4. The second heat dissipation hole 211 is preferably but not limited to a rectangular hole, and the second heat dissipation hole 211 can also be selected to be circular, triangular or polygonal. In this embodiment, a plurality of second heat dissipation holes 211 are provided, and the plurality of second heat dissipation holes 211 are spaced apart along the length direction of the bottom plate 21. The number of the second heat dissipation holes 211 is set according to the number of the extended portions of the radiator 4 (i.e., the bosses 43), and the positions and shapes are basically consistent, so as to facilitate the extended connection.

[0076] like Figure 1 As shown, the bottom plate 21 is also provided with an avoidance hole 212. A plurality of avoidance holes 212 are provided, and the plurality of avoidance holes 212 are arranged at intervals along the width direction of the bottom plate 21. The avoidance holes 212 are used to avoid the protruding structure on the shielding cage 3 when the radiator buckling structure is connected to the shielding cage 3, so as to improve the stability of the connection.

[0077] The heat sink snap-fit ​​structure of this embodiment is composed of a first snap-fit ​​part and a second snap-fit ​​part that are snap-fitted and connected to wrap the heat sink as a whole, thereby preventing the heat sink from being displaced or loosened when subjected to external impact or vibration, thereby ensuring its stability and reliability.

[0078] Fig.10 and Fig.11 Schematic diagram of the structure of the optical module and the shielding cage assembly. The shielding cage assembly includes a heat sink buckle structure, a shielding cage 3 and a heat sink 4. The heat sink buckle structure is consistent with the heat sink buckle structure in the above embodiment and will not be repeated. Figure 4 , Figure 5 As shown, the radiator 4 is installed in the accommodation space of the radiator buckle structure, which can prevent the radiator 4 from shaking up and down or left and right. The radiator 4 and the radiator buckle structure can be assembled and connected with the shielding cage 3 as a whole, so that the radiator 4 can be quickly adjusted according to different heat dissipation requirements, improving the assembly and disassembly efficiency.

[0079] The radiator 4 is preferably, but not limited to, a liquid-cooled radiator. The liquid-cooled radiator cools down the optical module 5 in the shielding cage 3 by passing a coolant into the radiator 4 , and has a better cooling effect.

[0080] like Figure 6-Figure 8As shown, the radiator 4 includes a liquid cooling plate 41 and a pressing plate 42. The pressing plate 42 is installed on the top surface of the liquid cooling plate 41 to ensure that multiple elastic pressing plates 112 can abut on the same plane to ensure the same degree of tightness. The pressing plate 42 is used to abut the elastic pressing plate 112 of the radiator snap-fit ​​structure to ensure that the radiator 4 and the optical module 5 are pressed tightly or to ensure that the radiator 4 and the multiple optical modules 5 are kept at a relatively close distance to prevent the radiator 4 from moving up and down. At the same time, the multiple elastic pressing plates 112 are pressed against the radiator 4 by abutting against the pressing plate 42, which can ensure that the radiator 4 and the multiple optical modules 5 have the same degree of tightness or distance, so that the heat dissipation of the multiple optical modules 5 is uniform, avoiding adverse effects caused by local overheating. The liquid cooling plate 41 is provided with an internal flow channel, and the internal flow channel is provided with a liquid outlet and a liquid inlet. The liquid outlet and the liquid inlet are respectively connected to the liquid storage device through a pipeline. The heat of the optical module 5 is taken away by the flow of the coolant in the internal flow channel to achieve heat dissipation and cooling.

[0081] like Figure 7 As shown, the heat sink 4 further includes a boss 43, which is protruding from the bottom surface of the liquid cooling plate 41. The number, position and shape of the boss 43 are consistent with the number, position and shape of the second heat dissipation holes 211. When the heat sink 4 is installed in the heat sink buckle structure, the boss 43 extends from the corresponding second heat dissipation hole 211.

[0082] In this embodiment, the second heat dissipation hole 211 is a rectangular through hole, and correspondingly, the boss 43 is a cuboid. In addition, the second heat dissipation hole 211 is substantially the same size as the boss 43, and the second heat dissipation hole 211 is aligned with the boss 43. Therefore, after the boss 43 extends from the second heat dissipation hole 211, it will not shake due to its size, and the structure is more stable. In some other optional embodiments, the second heat dissipation hole 211 can also be set as a circular, polygonal or irregular shaped through hole, and the boss 43 can also be set as other solid shapes, which is not limited in this embodiment.

[0083] like Fig. 9 As shown, the shielding cage 3 is provided with a second snap-fitting portion 31 snap-fittingly connected to the second snap-fitting portion 17 of the radiator snap-fitting structure on both sides. The number of the second snap-fitting portions 31 on each side of the shielding cage 3 is respectively consistent with the number of the second snap-fitting portions 17 on the third upper side plate 14 and the fourth upper side plate 15, and the positions are corresponding, which is convenient for firm installation and easy disassembly, and improves the stability of the connection. In this embodiment, the second snap-fitting portion 17 is a snap-fitting hole, and the second snap-fitting portion 31 is a hanging ear extending upward from both sides of the top surface of the shielding cage 3 and then bending toward the outside of the shielding cage 3. In addition, the second snap-fitting portion 31 can also be a convex block protruding toward the outside of the shielding cage 3. The snap-fitting hole can be triangular, rectangular, polygonal or circular, and the convex block can be triangular, rectangular, polygonal or circular.

[0084] like Fig. 9 As shown, the shielding cage 3 includes a receiving cavity 32, and the receiving cavity 32 is used to install the optical module 5. Fig. 9 As shown, a third heat dissipation hole 33 is provided on the top surface of the shielding cage 3, and the third heat dissipation hole 33 is connected to the accommodating cavity 32. The third heat dissipation hole 33 allows the boss 43 of the heat sink 4 to pass through and extend into the accommodating cavity 32, and then directly contact or get closer to the optical module 5, thereby improving the heat dissipation efficiency to a certain extent.

[0085] In this embodiment, a plurality of accommodating cavities 32 are arranged in parallel along the length direction in the shielding cage 3, and an optical module 5 can be installed in each accommodating cavity 32, so that the information interaction efficiency is higher. Accordingly, a plurality of third heat dissipation holes 33 are also provided, which correspond to the plurality of accommodating cavities 32 one by one. At the same time, a plurality of second heat dissipation holes 211 and bosses 43 are also provided, which correspond to the plurality of third heat dissipation holes 33 one by one. The plurality of bosses 43 extend into the corresponding third heat dissipation holes 33 and then extend into the corresponding accommodating cavities 32, and can directly contact or approach the optical module 5 at a close distance, so that the heat dissipation of the plurality of optical modules 5 is uniform and the heat dissipation efficiency is high.

[0086] In this embodiment, the accommodating cavity 32 is a rectangular hollow structure, the third heat dissipation hole 33 and the second heat dissipation hole 211 are rectangular through holes, and correspondingly, the boss 43 is a cuboid. In addition, the third heat dissipation hole 33, the second heat dissipation hole 211 and the boss 43 are substantially the same in size, and the third heat dissipation hole 33 and the second heat dissipation hole 211 are aligned with the boss 43. Therefore, after the boss 43 extends from the second heat dissipation hole 211 and the third heat dissipation hole 33, due to the comparable size, it will basically not shake, and the structure is more stable. In some other optional embodiments, the third heat dissipation hole 33 and the second heat dissipation hole 211 can also be set as circular, polygonal or irregular shaped through holes, and the boss 43 can also be set as other solid shapes, which is not limited in this embodiment.

[0087] This embodiment also provides an optical module device, which includes a shielding cage assembly and an optical module 5. The structure of the shielding cage assembly is consistent with the above, and will not be repeated. The optical module 5 is arranged in the accommodating cavity 32 of the shielding cage 3, and the number of the optical modules 5 is consistent with the number of the accommodating cavities 32.

[0088] In the embodiment of the present application, the radiator snap-fit ​​structure is set to a structure that can be wrapped around the outside of the radiator as a whole. After being connected to the shielding cage, it can ensure good contact between the radiator and the heat source (optical module), thereby improving the heat dissipation efficiency. The overall structure formed by the snap-fit ​​connection can provide better mechanical support, prevent the radiator from being displaced or loosened when subjected to external impact or vibration, and ensure its stability and reliability. The overall wrapping design can be quickly adjusted according to different heat dissipation requirements and is suitable for a variety of different devices and applications. The snap-fit ​​design of the radiator snap-fit ​​structure itself and the snap-fit ​​connection with the shielding cage can be installed or disassembled without tools, which simplifies the installation process, saves time and cost, and also facilitates later maintenance or replacement.

[0089] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
