[0047] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be described clearly and completely in combination with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are partial embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0048] Please refer to the attached Figure 1-Figure 14 The present invention proposes a heat dissipation structure of a high-speed connector, including a cage 110, a liquid cooling tube 140 and a heat dissipation assembly 150; the cage 110 is provided with a plurality of plug-in cavities 115 for placing a preset heat source module; the heat dissipation assembly 150 is arranged on the plug-in cavity 115, and the heat dissipation assembly 150 and the liquid cooling tube 140 are stacked; a placement hole 1153 is provided on one side of the plug-in cavity 115, a part of the heat dissipation assembly 150 passes through the placement hole 1153 and abuts against the heat source module in the plug-in cavity 115; the other part is located on the outer side of the plug-in cavity 115 and abuts against the liquid cooling tube 140; the plug-in cavity 115 includes an upper plug-in cavity 1151 and a lower plug-in cavity 1152, and a heat dissipation interlayer 120 is provided between the upper plug-in cavity 1151 and the lower plug-in cavity 1152 for placing the liquid cooling tube 140 and the heat dissipation assembly 150.

[0049] In this embodiment, the cage 110 is provided with a plurality of plug-in cavities 115, and the plug-in cavities 115 include an upper plug-in cavity 1151 and a lower plug-in cavity 1152. The plug-in cavity 115 is mainly used to place a preset heat source module, and a placement hole 1153 is provided on one side of the plug-in cavity 115, and the liquid cooling pipe 140 is arranged on the outside of the plug-in cavity 115. Among them, the heat dissipation assembly 150 includes at least a heat sink 151 and a heat sink block 152, and a heat sink 151 is provided with a heat sink groove 1521 corresponding to the placement hole 1153, and the heat sink groove 1521 is used to place the heat sink block 152, so that the heat sink block 152 can be fixed above the heat source module without displacement. The heat dissipation component 150 is arranged between the heat source module and the liquid cooling tube 140, and the heat dissipation component 150 and the liquid cooling tube 140 are stacked. Specifically, the heat dissipation groove 1521 of the heat dissipation component 150 passes through the placement hole 1153 and abuts against the heat source module in the plug-in cavity 115, and the heat dissipation groove 1521 is recessed toward the inner side of the plug-in cavity 115 so that the surface of the heat dissipation groove 1521 and the heat source module are more closely contacted, and the contact surface between the heat dissipation groove 1521 and the heat source module is adjusted by setting an elastic arm 1512 on the side of the heat dissipation groove 1521 to ensure that the contact surface between the heat sink 151 and the heat source module always maintains a good contact state; the heat dissipation block 152 is placed in the heat dissipation groove 1521, and one side of the heat dissipation block 152 abuts against the heat dissipation groove 1521, and the other side abuts against the liquid cooling tube 140. The heat generated by the heat source module is transferred to the heat sink 152 through the heat sink 1521. The heat sink 152 is in contact with the liquid cooling tube 140, so that the heat on the heat sink 152 can be transferred from the coolant circulating in the liquid cooling tube 140. The coolant in the liquid cooling tube 140 can provide a higher heat dissipation capacity than traditional air cooling. The thermal conductivity of the liquid is usually higher than that of the air, and it can more effectively take away the heat inside the connector, accelerate the heat dissipation of the connector, and thus improve the stability of the connector.

[0050] Please refer to Figure 2 , Figure 5 , Figure 8 and Fig.12 The heat dissipation assembly 150 at least includes a heat sink 151 and a heat sink block 152. The heat sink 151 is provided with a heat dissipation groove 1521 corresponding to the placement hole 1153. The heat dissipation groove 1521 is used to place the heat dissipation block 152 and make the heat dissipation block 152 abut against the liquid cooling tube 140, and the heat dissipation groove 1521 abuts against the heat source module.

[0051] In specific implementation: a heat sink 151 is provided with a heat sink groove 1521 for placing a heat sink block 152, so that the heat sink block 152 can be fixed on the heat source module to prevent the heat sink block 152 from being displaced or damaged, thereby affecting the heat dissipation of the heat source module. The side of the heat sink block 152 away from the heat sink groove 1521 abuts against the liquid cooling tube 140, so that the heat on the heat sink block 152 can be transferred from the coolant in the liquid cooling tube 140, so that the heat dissipation efficiency of the heat sink block 152 is higher, and the heat dissipation of the connector is faster, thereby improving the stability of the connector. The heat sink block 152 includes but is not limited to thermally conductive silicone, epoxy resin thermally conductive glue, polyurethane thermally conductive glue, metal filler thermally conductive glue, hot water conductive gel and ceramic thermally conductive glue.

[0052] The heat source module is arranged in the plug-in cavity 115, and a placement hole 1153 is provided on one side of the plug-in cavity 115. The heat dissipation groove 1521 of the heat dissipation component 150 is arranged in the placement hole 1153, and the bottom of the heat dissipation groove 1521 is abutted against the heat source module, and the heat dissipation groove 1521 has a flat contact surface, so that the heat transfer of the heat source module is more stable.

[0053] In a specific embodiment, the heat sink 152 can be removed from the heat sink 1521 to replace an aged or damaged heat sink 152. At the same time, the heat sink 1521 and the heat sink 152 can be cleaned regularly to prevent dust, corrosion and other problems from affecting the heat dissipation performance of the heat sink 150.

[0054] Please refer to Figure 3 , Figure 5 , Fig.11 and Fig.13 The heat dissipation groove 1521 is recessed toward the inner side of the plug-in cavity 115 and abuts against the heat source module.

[0055] In specific implementation: the heat dissipation groove 1521 is recessed toward the inner side of the plug-in cavity 115 so that the surface of the heat dissipation groove 1521 is more closely in contact with the heat source module, thereby ensuring that the contact surface between the heat sink 151 and the heat source module always maintains a good contact state, avoiding poor contact between the surface of the heat dissipation groove 1521 and the heat source module, and affecting the heat transfer of the heat source module.

[0056] Please refer to Figure 2 and Figure 12-14 The heat sink 151 is provided with a fixing portion 1511 and an elastic arm 1512 . The elastic arm 1512 is provided between the heat dissipation slot 1521 and the fixing portion 1511 . The fixing portion 1511 is provided on the plug-in cavity 115 .

[0057] In specific implementation: the heat sink 151 is provided with an elastic arm 1512, which is specifically located between the heat sink 1521 and the fixing portion 1511; and the heat sink 151 is fixed to the plug-in cavity 115 through the fixing portion 1511, so that the heat sink 1521 can be fixed in the placement hole 1153. Through the adjustment of the elastic arm 1512, the heat sink 1521 and the heat source module are kept in good close contact and continuous pressure is maintained, and the contact surface of the heat sink 151 and the heat source module is ensured to always maintain a good contact state, avoiding poor contact due to thermal expansion and contraction or external force, affecting the heat dissipation effect of the connector, and at the same time, the heat source module can be neither too loose to cause poor contact nor too tight to cause difficulty in plugging or damage when plugging and unplugging.

[0058] In a specific embodiment, the elastic arm 1512 disposed between the heat dissipation slot 1521 and the fixed portion 1511 is wavy in shape, which can disperse stress when the elastic arm 1512 is bent, reduce concentrated stress points, and reduce the risk of material fatigue or fracture due to excessive bending; at the same time, it can also better absorb and buffer the impact and vibration during the plugging and unplugging process to reduce the impact on the internal components of the connector.

[0059] Please refer to Figure 5 , Figure 8 and Figure 11-Figure 14 The fixing portion 1511 is provided with a plurality of fixing holes 15111 , and the cage 110 is provided with a plurality of fixing feet 113 corresponding to the fixing holes 15111 .

[0060] In specific implementation: the fixing portion 1511 on the heat sink 151 is provided with a plurality of fixing holes 15111, and the heat sink 151 is connected to the plug-in cavity 115 through the fixing holes 15111. Specifically, the plug-in cavity 115 of the cage 110 is provided with fixing feet 113 corresponding to the fixing holes 15111, and the fixing feet 113 penetrate the fixing holes 15111 of the fixing portion 1511 and are fixedly connected to the fixing holes 15111. The connection methods include but are not limited to riveting, welding and laser connection.

[0061] Please refer to Figure 8-Figure 10 The cage 110 includes a frame 111 and a shell 112, wherein the shell 112 includes an upper shell 1121 and a lower shell 1122; a part of the frame 111 and the lower shell 1122 constitute an upper plug-in cavity 1151, and another part of the frame 111, the upper shell 1121 and the lower shell 1122 constitute a lower plug-in cavity 1152.

[0062] In the specific implementation: one side of the frame 111 is in an inverted U shape; a part of the frame 111 and the lower shell 1122 constitute an upper plug-in cavity 1151, and the heat dissipation assembly 150 is arranged on the frame 111 away from the heat dissipation barrier 120; another part of the frame 111, the upper shell 1121 and the lower shell 1122 constitute the lower plug-in cavity 1152. Among them, the heat dissipation assembly 150 is constructed on the upper shell 1121, and together with the upper shell 1121, it constitutes a heat dissipation module 160, which is convenient for subsequent disassembly and assembly. Among them, the connection between the shell 112 and the frame 111 is a detachable setting.

[0063] Please refer to Fig.11 The upper shell 1121 and the heat dissipation assembly 150 constitute a heat dissipation module 160 .

[0064] In specific implementation: the heat dissipation component 150 is arranged on the frame 111 and the shell 112. Specifically, when the heat dissipation component 150 is arranged in the upper plug-in cavity 1151, the heat dissipation component 150 is mainly arranged on the frame 111; when the heat dissipation component 150 is arranged in the lower plug-in cavity 1152, the heat dissipation component 150 is mainly arranged on the shell 112.

[0065] When the heat dissipation assembly 150 is arranged on the side of the plug-in cavity 115 close to the heat dissipation isolation layer, specifically located in the heat dissipation isolation layer 120, and only the heat dissipation assembly 150 is disassembled, the difficulty increases and the flatness of the plug-in cavity 115 is easily damaged. The heat dissipation assembly 150 can form a heat dissipation module 160 with the upper shell 1121 or the lower shell 1122. When the heat dissipation assembly 150 needs to be repaired or replaced, the upper shell 1121 or the lower shell 1122 (i.e., the heat dissipation module 160) can be disassembled.

[0066] In a specific embodiment, when the heat dissipation assembly 150 is arranged on the lower plug-in cavity 1152 of the connector, the heat dissipation structure is specifically arranged on the upper shell 1121 of the lower plug-in cavity 1152, and forms a heat dissipation module 160 with the upper shell 1121 of the lower plug-in cavity 1152. When the heat dissipation structure is damaged or aged, the detachable setting of the upper shell 1121 of the lower plug-in cavity 1152 makes the process of replacing the heat dissipation structure more convenient and quick, and there is no need to disassemble the entire plug-in cavity 115 of the connector. It is only necessary to disassemble the upper shell 1121 (i.e., the heat dissipation module 160) to replace the heat dissipation structure, thereby reducing maintenance costs and time. At the same time, the upper shell 1121 of the lower plug-in cavity 1152 constitutes the heat dissipation module 160, which makes the assembly process of the connector simpler and quicker, and improves the assembly efficiency.

[0067] Please refer to Figure 1 , Figure 5 and Figure 8-Figure 10The upper shell 1121 and the lower shell 1122 are respectively provided with a plurality of notches 1123 , and some of the notches 1123 are provided with extension portions. The frame 111 is provided with a plurality of protrusions 1111 corresponding to the notches 1123 , and the notches 1123 are engaged and fixed with the protrusions 1111 .

[0068] In the specific implementation: the housing 112 is provided with a notch 1123, and part of the notch 1123 is provided with an extension. The frame 111 is provided with a protrusion 1111 corresponding to the notch 1123, and the height of the protrusion 1111 is different, wherein the protrusion 1111 includes a first protrusion 11111 and a second protrusion 11112, and the height of the first protrusion 11111 is greater than the height of the second protrusion 11112, so that the first protrusion 11111 can abut against the extension in part of the notch 1123 during assembly, and the first protrusion 11111 of the frame 111 can realize vertical support of the housing 112; the second protrusion 11112 cooperates with the notch 1123 during assembly to limit and fix the housing 112, and prevent the housing 112 from shifting in the horizontal direction.

[0069] Please refer to Figure 1 , Figure 4 , Figure 5 and Figure 8 The cage 110 is further provided with a buckle 1112 , a bayonet 1124 and a guide structure 114 , and the bayonet 1124 corresponds to the buckle 1112 , and the guide structure 114 is located at the side of the plug-in cavity 115 .

[0070] In a specific implementation: the buckle 1112 is provided on the frame 111, specifically located on the side of the frame 111, and the bayonet 1124 is provided on the shell 112, and the specific position of the bayonet 1124 corresponds to the buckle 1112. During assembly, the buckle 1112 on the frame 111 is engaged with the bayonet 1124 on the shell 112 to make the connection between the frame 111 and the shell 112 more secure.

[0071] The guide structure 114 is arranged on the side of the plug cavity 115, and includes a dovetail-shaped plug and a slot. The plug and the slot cooperate to enable the assembly of the housing 112 of the plug cavity 115 of the connector to be completed more quickly and accurately, and the guide structure 114 can be quickly connected or disassembled by simply inserting or removing the plug and the slot, avoiding a complicated assembly process.

[0072] Please refer to Figure 12-14 The elastic arm 1512, the fixing portion 1511 and the heat sink 151 are integrally formed.

[0073] In a specific implementation, the heat sink 151 is formed with a heat sink 1521, an elastic arm 1512 and a fixing portion 1511, wherein the elastic arm 1512 is specifically arranged between the heat sink 1521 and the fixing portion 1511. The heat sink 151 is integrally formed, thereby avoiding failures caused by poor connection at connection points or seams, loose components or aging, and at the same time, reducing labor, equipment and man-hour costs, making the manufacturing process simpler and more efficient.
