DETAILED DESCRIPTION

[0050] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0051] For the accuracy of the description of the entire application, please refer to Figure 1 For reference, specifically: the direction of the X-axis is defined as the left-right direction; the direction of the Y-axis is defined as the up-down direction, where the positive direction of the Y-axis is upward; the direction of the Z-axis is defined as the front-back direction (that is, the docking direction with the docking connector), where the positive direction of the Z-axis is rearward.

[0052] Please refer to Figures 1 to 5 FIG. 1 shows a heat dissipation shielding cage assembly disclosed in the present application. Specifically, the heat dissipation shielding cage assembly includes a cage assembly 1, a first heat dissipation member 2, and a second heat dissipation member 4 assembled to the cage assembly 1. The cage assembly 1 is made of sheet metal and includes a top plate 11, two side plates 12 located on either side of the top plate 11, a bottom plate 13 disposed opposite the top plate, and a rear plate 14 coupled to the rear ends of the top plate 11 and side plates 12. The top plate 11, two side plates 12, bottom plate 13, and rear plate 14 collectively enclose a docking cavity 10, with an insertion port 101 formed at one end.

[0053] In the present application, preferably, the top plate 11, the two side plates 12, and the rear end plate 14 are made of the same metal plate, and the bottom plate 13 is a separate component and is fixed to the two side plates 12 by assembly. The bottom plate 13 may include a main plate 1301 and fixed side plate portions 1302 extending upward from both sides of the main plate 1301 in the left-right direction. The fixed side plate portions 1302 are correspondingly fixed to the outer side surfaces of the side plates 12. Specifically, this can be achieved by engaging snap holes (unnumbered) formed on the fixed side plate portions 1302 with snap protrusions (unnumbered) formed on the side plates 12. In a preferred embodiment of the present application, the bottom plate 13 and the side plates 12 are connected by a downwardly extending docking pin 121. The docking pin 121 is used to secure to a docking substrate (not shown, which can be a circuit board inside an electronic device). In one embodiment, the docking pin 121 is formed by further extending downward from the lower edge of the side plate 12 and passing downward through the bottom plate 13. In addition, the side panel 12 can also achieve a limiting and fixing function with the bottom panel 13 through the docking pins 121 .

[0054] Please refer to Figures 3 to 5 As shown, the main plate 1301 of the base plate 13 has a mounting hole 131 formed vertically through it near the insertion port 101. The edges of the mounting hole 131 of the base plate 13 extend into the mounting hole 131 to form cantilevered extension springs 132 (specifically, each extension spring 132 extends in the front-to-back direction and is inclined downward). Limiting slots 133 are also formed on both sides of the base plate 13 in the left-to-right direction. These limiting slots 133 penetrate the base plate 13 vertically, with one end extending to communicate with the mounting hole 131 and the other end extending to the corresponding side plate 12. In a preferred embodiment, the other end of the limiting slot 133 extends to the fixed side plate portion 1302. In the embodiment of the present application, the mounting hole 131 is in a rectangular shape, and there are four extending spring pieces 132, which are respectively located in pairs on the two hole wall edges extending along the left and right directions of the mounting hole 131; there are four limiting grooves 133, which are respectively located in pairs on the two hole wall edges extending along the front and rear directions of the mounting hole 131.

[0055] Please refer to Figures 2 to 5As shown, the first heat sink 2 includes a main body 21 and a support portion 22 formed by further extending outward from the edge of the main body 21. In the embodiment of the present application, the first heat sink 2 also includes an auxiliary fin portion 211, which is combined with the lower surface of the main body 21. The first heat sink 2 is installed and assembled to the bottom plate 13. Specifically, at least a portion of the main body 21 is assembled into the mounting hole 131, and the support portion 22 is assembled into the limiting groove 133 and stops upward on the side plate 12. The extended spring 132 elastically abuts against the lower surface of the main body 21 from bottom to top. In a preferred embodiment, the lower surface of the main body 21 is recessed upward at both end positions along the front-to-back direction (corresponding to the position of the extended spring 132) to form a limiting groove 210, and the extended spring 132 elastically abuts against the limiting groove 210 from bottom to top.

[0056] In a preferred embodiment, the first heat sink 2 can be first installed on the bottom plate 13, and then the bottom plate 13 combined with the first heat sink 2 is assembled from bottom to top onto the side plate 12. The first heat sink 2 is assembled from top to bottom onto the bottom plate 13. During this process, the support portion 22 of the first heat sink 2 scrapes over the inner surface of the corresponding fixed side plate portion 1302 from top to bottom and then falls into the limiting groove 133.

[0057] Please refer to Figure 1 and Figures 3 to 5 As shown, the top plate 11 is formed with an assembly hole 110 extending through it in the vertical direction near the insertion port 101. The second heat sink 4 is stacked and assembled on the top plate 11. The second heat sink 4 includes a main body 41 stacked on the upper surface of the top plate 11 and an extension 43 extending further rearward from the main body 41 and beyond the rear end plate 14. Furthermore, the second heat sink 4 is also provided with an upper fin portion 44 and a lower fin portion 45. The upper fin portion 44 is coupled to the upper surface of the main body 41 and the upper surface of the extension portion 43, and the lower fin portion 45 is coupled to the lower surface of the extension portion 43. The lower fin portion 45 is located at the rear end plate 14.

[0058] Please refer to Figure 4 and Figure 5As shown, the lower surface of the main body 41 of the second heat sink 4 is recessed upward to form a recessed groove 40. In this embodiment, the heat shielding cage assembly further includes a flat heat pipe 5, which is coupled to the recessed groove 40. The flat heat pipe 5 is preferably made of a copper tube and forms a vacuum cavity (unnumbered). A liquid working medium is implanted in the vacuum cavity. A capillary structure (unnumbered) is coupled to the inner wall surface of the vacuum cavity formed by the flat heat pipe 5. When one end of the flat heat pipe 5 is heated, the heat is rapidly transferred to the interior of the flat heat pipe 5 through the wall of the flat heat pipe 5. The working fluid (such as water) in the capillary structure at the corresponding position inside the flat heat pipe 5 will quickly vaporize and absorb a large amount of heat. The vaporized water vapor will quickly diffuse within the vacuum cavity inside the flat heat pipe 5 and, after cooling, form water droplets that are adsorbed on the capillary structure at the corresponding position, thereby rapidly diffusing the heat to various positions of the flat heat pipe 5. The capillary structure will pull the water droplets back to the heated and evaporated position due to capillary penetration, thereby forming a gas-liquid two-phase cycle and achieving rapid heat transfer. In a preferred embodiment, the extension length of the recessed groove 40 in the front-to-back direction covers more than 90% of the extension length of the main body 41 in the front-to-back direction, and the extension width of the recessed groove 40 in the left-to-right direction covers more than 60% of the extension width of the main body 41 in the left-to-right direction. The flat heat pipe 5 matches the recessed groove 40, thereby achieving a larger contact area between the flat heat pipe 5 and the main body 41 and improving heat transfer efficiency.

[0059] Furthermore, the position of the mounting hole 131 on the lower surface of the flat heat pipe 5 is also covered with a cover 6, and at least a portion of the cover 6 protrudes downward through the assembly hole 110 into the docking cavity 10 for contacting the docking connector (not shown) inserted into the docking cavity 10 through the insertion port 101. In a preferred embodiment, the cover 6 is overlapped and coupled to the lower surface of the main body 41 on both sides along the left and right directions. In one embodiment, the cover 6 can be a soft thermal conductive paste with good thermal conductivity; in another embodiment, the cover 6 can also be a metal block with good thermal conductivity (such as a copper block), which can be directly fixed to the flat heat pipe 5 and the main body 41 by welding.

[0060] Please refer to Figure 4 and Figure 5 As shown, in the embodiment of the present application, the flat heat pipe 5 includes a portion extending to the upper surface of the rear end of the assembly hole 110 located on the top plate 11. Figures 1 to 5As shown, in the embodiment of the present application, the heat dissipation shielding cage assembly further includes a radiator bracket member 7, which straddles the second heat dissipation member 4 in the left-right direction and has corresponding clips on both sides that fit on the outer surface of the side panel 12, so as to fix the second heat dissipation member 4 to the cage assembly 1. Preferably, the second heat dissipation member 4 can float within a specific range in the up-down direction. Specifically, when the docking connector is inserted into the docking cavity 10 through the insertion port 101, the docking connector pushes the second heat dissipation member 4 upward, thereby ensuring stable and reliable contact between the second heat dissipation member 4 and the docking connector, and reducing the contact thermal resistance between the two.

[0061] In the embodiment of the present application, by providing the first heat sink 2, the second heat sink 4, and the flat heat pipe 5, a rapid heat dissipation effect can be achieved, and all-round rapid heat dissipation can be achieved by utilizing the positions above, below, and behind the cage assembly 1. Of course, in some special usage scenarios, such as when the space inside the device is limited, some modified implementation methods can also be made, as follows:

[0062] Please refer to Figure 6 As shown, the second embodiment of the heat dissipation shielding cage assembly of the present application is shown.

In the second embodiment, the top plate 11 is a flat plate and is not provided with any through-hole structure.

[0063] Please refer to Figure 7 As shown, this is the third embodiment of the heat dissipation shielding cage assembly of the present application. The third embodiment is actually a modified example of the second embodiment. The only difference between the third embodiment and the second embodiment is that in the third embodiment, a plurality of auxiliary heat dissipation holes 1101 are formed through the top plate 11 in the up and down directions.

[0065] Please refer to Figure 9 As shown, this is the fifth embodiment of the heat dissipation shielding cage assembly of the present application. The fifth embodiment is actually a variation of the third embodiment.

[0066] Please refer to Figure 10As shown, this is the sixth embodiment of the heat dissipation shielding cage assembly of the present application. The sixth embodiment is actually the first embodiment ( Figures 1 to 5 As shown in FIG6 , the only difference between the sixth embodiment and the first embodiment is that in the sixth embodiment, the auxiliary fin portion 211 is not provided on the first heat dissipation member 2.

[0067] The heat shield cage assembly described herein can generally be used in conjunction with one or more connector modules (not shown) to form a complete electrical connector, which can be mounted on a circuit board (not shown) within a device such as a base station.
