The second fastening hole 109 of the block 217 (see FIG. 5) is used to fasten the metal heat sink 100 to the shield case 200 (see FIG. 4). However, the disclosure is not limited thereto. 4 is a schematic view showing the combination of the shield assembly 300 of FIG. 1. 5 is a cross-sectional view of the shield assembly 300 of FIG. 4 taken along line AA'. Referring to FIGS. 4 and 5, the metal heat sink 100 is assembled from the top to the bottom in the up and down direction D2 to the shield case 200. When the metal heat sink 100 is assembled to the shield case 200, the first side fixing portion of the metal heat sink 100 The first side fixing portion 105 and the second side fixing portion 105 are respectively fastened to the first side wall 206 and the second side wall 216 of the shielding case 200 . The simply supported plate body 108, the front connecting portion 116 and the rear connecting portion 114 of the metal heat sink 100 will be located in the opening 209 of the top wall 208 of the shield case 200 and extend into the insertion space 210 of the shield case 200. Before the metal heat sink 100, the support portion 102 and the rear support portion 104 are located on the upper surface of the top wall 208 before and after the opening 209 of the shield case 200. In some embodiments, the first upper flange 110 and the second upper flange 111 of the simply supported plate body 108 of the metal heat sink 100 are pressed against the upper surface of the top wall 208 on both sides of the opening 209 of the shield case 200. When a plug module (not shown) is inserted into the shield case 200, the plug module enters the plug space 210 of the shield case 200 from the socket 203 of the shield case 200, and the process is transparent to the metal heat sink 100. The front connecting portion 116 guides the smooth insertion of the plug module, and the plug module elastically pushes the simple supporting plate body 108 through the front connecting portion 116 until the bottom surface of the simply supported plate body 108 is pressed against the plug mold. The top surface of the group is completed and docked. Since the simple supporting plate body 108 is separated from the first side fixing portion 106 and the second side fixing portion 105, when the simple supporting plate body 108 is pushed up by the plug module, the upward thrust is not directly transmitted to the metal heat dissipation. The first side fixing portion 106 and the second side fixing portion 105 are provided with 100. More specifically, the upward thrust is transmitted to the front support portion 102 and the rear support portion 104 via the simply supported plate body 108, and then transmitted to the first side fixing portion 106 and the second side fixing portion 105. Therefore, it is possible to better avoid the case where the first side fixing portion 106 and the second side fixing portion 105 of the metal heat sink 100 are separated from the shield case 200, and ensure that the metal heat sink 100 is firmly fastened to the shield case 200.

According to this, it is possible to more effectively prevent the first side fixing portion 106 and the second side fixing portion 105 of the metal heat sink 100 from being separated from the shield case 200. The front connecting portion 116 is configured to guide the plug module inserted into the receiving space 210. Since the front connecting portion 116 is connected to the front support portion 102 of the metal heat sink 100, when the plug module is withdrawn from the plug-in space 210 of the shield case 200, the simple-supported plate body 108 is returned due to the recovery of the elastic force. In the insertion space 210, the front support portion 102 can be blocked by the top wall 208 of the shield case 200, and the front connection portion 116 can be prevented from falling into the insertion space 210 as a whole. Similarly, the rear support portion 104 can also be The stop limit is on the top wall 208 of the shield housing 200. In this way, when the plug module is reinserted next time, the insertion of the plug module is not hindered, and damage to the metal heat sink 100 and the plug module can be avoided. 6 is a cross-sectional view of the shield assembly 300 of FIG. 4 taken along line BB'.

The upper surface of the top wall 208 on the left and right sides of the opening 209 of the shield case 200 is shielded, so that the looseness of the combination of the metal heat sink 100 and the shield case 200 or the sound due to looseness can be avoided. Moreover, when the plug module is withdrawn from the insertion space 210 of the shield case 200, the first upper flange 110 and the second upper flange 111 on both sides of the simply supported plate body 108 are returned to be pressed against the shield case. The state of the top wall 208 of the body 200 causes the simply supported plate body 108, the front connecting portion 116 and the rear connecting portion 114 to be located in the insertion space 210 of the shielding case 200 when the simple supporting plate body 108 is returned to the plug without being inserted. The initial state, and it can be ensured that the position of the simply supported plate body 108 in the docking space 210 can be kept constant even in the non-plugged state even after multiple insertions. In an embodiment, as shown in FIG. 5, before the plug module is not inserted, the front support portion 102 and the rear support portion 104 of the metal heat sink 100 may also support the top wall of the front and rear of the opening 209 of the shield case 200. The upper surface of the 208, when the plug module is withdrawn from the insertion space 210 of the shield case 200, the front support portion 102 and the rear support portion 104 are returned to the state supported by the top wall 208 of the shield case 200, so that When the support plate body 108 is returned to the plug without insertion, the simple support plate body 108, the front connection portion 116, and the rear connection portion 114 are located in the initial state in the insertion space 210 of the shield case 200. In an embodiment, the first upper flange 110, the second upper flange 111, the front support portion 102, and the rear support portion 104 on both sides of the simple support plate body 108 may be in a state in which the plug module is not inserted.
