detailed description

Please refer to FIG. 1 . In a preferred embodiment of the present invention, an expansion card fixing device 100 includes a top cover 10 and a box body 20 . The expansion card fixing device 100 is used for fixing a plurality of expansion cards 26 . In one embodiment, the expansion card 26 is a sound card, a network card, a video capture card, a PCI graphics card, and the like. A connecting piece 262 is mounted on a front end of each expansion card 26 .

Please continue to refer to FIG. 2 and FIG. 3 , the upper cover 10 includes a board body 12 and a fixing part 14 , and the fixing part 14 is fixed on the board body 12 . In one embodiment, the board body 12 is riveted to the fixing member 14 , and the fixing member 14 is a rectangular board body substantially parallel to the board body 12 . The fixing member 14 includes a pressing plate 140 , two elastic pieces 142 and two fixing pieces 144 . The resisting plate 140 defines two openings 1402 . The two elastic pieces 142 extend from the resisting plate 140 and are respectively located in the two openings 1402 . Each elastic piece 142 includes a resisting portion 1420 . The resisting portion 1420 protrudes from the opening 1402 . The two fixing pieces 144 extend from the pressing plate 140 and are substantially perpendicular to the pressing plate 140 . Each fixing piece 144 defines a fixing hole 1440 .

The box body 20 includes a side panel 22 , a flange 23 extending from the side panel 22 , and a mounting frame 24 mounted on the flange 23 . The installation frame 24 includes a body 240 and two installation parts 242 . The main body 240 protrudes from a plurality of protrusions 2401 for positioning the connecting piece 262 . The two mounting portions 242 respectively extend from opposite ends of the body 240 . In one embodiment, each mounting portion 242 is substantially L-shaped, and includes a mounting piece 244 and a positioning piece 246 connected to the mounting piece 244 . In one embodiment, the positioning piece 246 extends from the body 240 and is substantially perpendicular to the body 240 . The mounting piece 244 extends from the positioning piece 246 and is perpendicular to the positioning piece 246 . The mounting piece 244 is substantially parallel to the body 240 . The mounting piece 244 has a mounting hole 2440 , and the positioning piece 246 has a protrusion 2460 .
