The flange 212 is provided with a plurality of fastening pieces 213. Each of the fastening pieces 213 is provided with two bending pieces 214 which are vertically bent by the folding edge 212. . Referring to FIG. 2 and FIG. 3, the shielding device 10 includes a bracket 11 and a resilient arm 12; the bracket 11 is provided with a front panel 13, a side panel 14, an upper panel 15 and a lower panel 16; the front panel 13 is provided a plurality of mounting holes 131, a circular opening 132 through which a finger can pass, and a movable opening 133 disposed on a side away from the side plate 14; the side plate 14 is provided with an elastic locking portion having a free end 141, the two sides of the latching portion 141 extend outwardly to form a pair of card M311931 hooks 142, each of the hooks 142 is provided with an obliquely extending transition edge 1421; the upper plate 15 is outwardly convex and has four free ends. a grounding elastic piece 151; the free end of the grounding elastic piece 151 is provided with an inwardly extending flap 1511; the upper plate 15 is formed to extend to an edge of the computer magnetic frame 20 to form an edge of the upper plate 15 and the front plate 13 An outer edge 152 has a circular arc shape in the embodiment. The lower plate 16 has three grounding elastic pieces 161 similar in structure to the grounding elastic piece 151. The lower plate 16 is also provided. There is an outer edge 162 corresponding to the outer edge 152; the distance between the outer edges 152, 162 and the hook ® 142 is less than the computer The horizontal distance between the two side walls 21, 22 of the frame 20; the elastic arm 12 extends from the side of the front plate 13 away from the side plate 14 away from the bracket 11, the end of the resilient arm 14 is adjacent to the The bracket 11 extends in the direction to form a flap 121. Referring to FIG. 1 , FIG. 4 and FIG. 5 , when the shielding device 10 is installed in the computer magnetic frame 20 , the shielding device 10 is first placed horizontally, and the shielding device 10 and the computer magnetic frame 20 are guided by one pair. Corresponding to the portions 211 and 221, φ at this time, the side plate 14 of the shielding device 10 corresponds to the folded edge 212 of the computer magnetic frame 20, and the elastic arm 12 is pressed inwardly so that the flap 121 of the elastic arm 12 can be placed therein. In the computer magnetic frame 20, the shielding device 10 is pushed into the computer magnetic frame 20. The transition edge 1421 of the hook 142 of the locking portion 141 is opposite to the outer edge of the locking piece 213, so that the locking portion 141 is deformed. The retracting device 10 is retracted into the movable opening 133 of the front panel 13 to push the shielding device 10 into the computer magnetic frame 20 until the transition edge 1421 of the hook 142 slides over the locking tab 213. At this time, the locking portion 141 The elastic hooks are placed on the inner side of the snap tab 213 and are blocked by the snap tab 213 to be transported to the M311931; the elastic arm 12 is elastically deformed to abut the side wall 22 of the computer magnetic rack 2 On the inner side, the shielding device 10 is fixed in the computer magnetic frame 2〇. _ Referring to FIG. 6 , when the shielding device 10 is disassembled, the finger is buckled into the circular hole 132 of the front plate 13 to pull the shielding device 1 向外 outward. At this time, the hook 142 of the side plate 14 is against the computer. The locking piece 213 of the magnetic frame 2 is rotated by the shielding device 10 to the outside of the computer magnetic frame 2 with the hook 142 as a fulcrum, because the distance between the outer edges 152, 162 and the hook 142 Less than the horizontal distance between the two side walls 21, 22 of the computer magnetic frame 20, the bracket n does not interfere with the side wall 22 of the computer magnetic frame 2〇 during the outward rotation; the elastic arm 12 The flap 121 is folded in a direction close to the bracket η. When the fold # 121 of the elastic arm 12 is moved to the edge of the side wall 22 of the computer magnetic frame 20, the elastic arm 12 is in a natural state, and the computer The (4) 22 of the magnetic frame 2G is not in contact with each other. At this time, the shielding device 10 is pulled in the direction of the side wall 22, and the hook 142 of the side plate 14 can be engaged with the side wall 21 of the computer magnetic frame 20. The 213 is separated, and the shielding device 10 is removed. In the above embodiment, the circular hole 132 of the front plate 13 of the bracket u can also be replaced by other common pulling portions for facilitating the pulling of the shielding device 1; the locking portion can also be disposed on the front plate 13.
