The first slit 1442 faces the second edge 146, and the second slit 1462 faces the first edge 144, and the first slit 1442 is offset from the orientation of the second slit 1462. The distance between the two first slits 1442 is smaller than the distance between the second slits 1462. The cover body 20 has a substantially rectangular plate structure, and the cover body 20 is obtained by punching the frame 10 and forming the opening 142 on the frame 10. The cover body 20 includes a plate portion 22 and two first lugs 7 201018386 24 and two second lugs 26 formed on two sides of the plate portion 22 . The plate portion 22 is sized to correspond to the central hole 1422 and is formed after the central hole 1422 is opened. The plate portion 22 is provided with two detaching holes 222 and a plurality of through holes 224. The two detaching holes 222 are located at opposite corners of the plate portion 22 to facilitate the detachment of the cover 20 from the frame 10. The through hole 224 facilitates heat dissipation of the electronic components under the shield 100. The two first lugs 24 are formed by punching the two first slits 1442, and the two second lugs 26 are formed by punching the two second slits 1462. The cover body 20 is welded to the frame 10, the two first lugs 24 are welded to the second edge 146 of the frame 10, and the second first slits 24 and the second edges 146 are second cuts. The position of 1462 is staggered, that is, the first lug 24 does not fall into the two first slits 1462, and the positional relationship of the second lug 24 with the first slit 1442 of the first edge 144 is also convenient to facilitate welding. Referring to Fig. 5, when the shield 100 is made, a sheet of metal material is first provided, and then the sheet is stamped to form the frame 10 and the cover 20 separated from the frame 10. The frame 10 includes the side walls 12 and the top frame 14. The side wall 12 is formed with a snap hole 122, and the top frame 14 is formed with the opening 142, the two first slits 1442 and the second slits 1462. The cover 20 is obtained by punching the opening 142 of the top frame 14. The cover body 20 is further formed with the two first lugs 24, the second second lugs 26 and the second dismounting holes 222. Then, as shown in FIG. 5, the cover 20 is rotated 180 degrees about its center line 0-0, and then the cover 20 is attached to the frame 10, such that the first lug 24 of the cover 20 The first slit 1442 is misaligned with the corresponding second slit 1462 and its corresponding second slit 1462 is misaligned. The first lug 24 of the cover 20 is welded to the second 201018386 edge 146 of the frame 10, and the second lug 26 of the cover 20 is correspondingly welded to the first edge 144 of the frame 10. Then, the manufacturing of the shield 100 is completed. When it is necessary to repair the electronic components (not shown) in the shield 100, the service tool passes through the removal hole 222 of the cover 20, and then the cover 20 is opened, the cover 20 is on the first lug. 24. The weld of the second lug 26 and the top frame 14 is separated from the frame 10. When the frame 10 needs to be shielded after maintenance, only a cover (not shown) is provided on the frame 10, and the convex hull of the periphery of the cover is engaged with the buckle hole 122 of the frame 10. . In summary, the frame 10 and the cover 20 of the shield 100 can be directly stamped from a metal sheet, and the frame 10 and the cover 20 need not be separately formed, and the cover 20 is a piece of material when the frame 10 is fabricated. After punching the opening 142 of the frame 10, it is not necessary to separately manufacture the cover 20 with a new sheet, which saves material. In addition, the shield cover 100 only needs to directly solder the cover body 20 to the frame 10. The first lug 24 and the second lug 26 are directly welded to the second edge 146 of the frame 10 and the first edge 144, and the welding is convenient. . In addition, _ avoids the traditional precision of the scoring, and the manufacturing method of the shield 100 is simple. It can be understood that the first slit 1442 and the second slit 1462 can also be oppositely opened. When the cover 20 is welded to the frame 10, it is only necessary to ensure that the first lug 24 of the cover 20 corresponds to the first cut. The mouth 1442 is misaligned, and the second lug 26 is misaligned with its corresponding second slit 1462.
