Please refer to FIG. 4 to FIG. 7 at the same time, the expansion card fixing device 40 includes a rear window 42 disposed on the base 10 , a fixing frame 44 and two fasteners 46 . The rear window 42 is the same as the existing rear window in the electronic equipment casing, and includes a square rear panel 48 and a frame 50 vertically assembled on the rear panel 48 . The rear panel 48 defines a plurality of I/O windows 480 corresponding to the I/O mask 34 of the expansion card 30 . The frame 50 includes a bottom wall 52 , two side walls 54 and a top plate 56 . The inner surface of each side wall 54 includes a fixing hole 540 near the bottom wall 52 , a protrusion 542 obliquely below the fixing hole 540 , and two engaging slots 544 arranged from top to bottom near the top plate 56 . Honeycomb holes are opened on the bottom wall 52 .

The fixing frame 44 is U-shaped and includes a pressing portion 60 and pivoting pieces 70 perpendicular to two ends of the pressing portion 60 . The cross-section of the pressing portion 60 is roughly U-shaped and divided into two layers, which includes a first buckle plate 62 and a second buckle located below the first buckle plate 62 and roughly parallel to the first buckle plate. The plate 64 , an accommodating space 65 formed by the first buckling plate 62 and the second buckling plate 64 , and an entrance 66 entering the accommodating space 65 . The second locking plate 64 is formed by bending the first locking plate 62 downward along the length direction to one side and then inward. The center of the first locking plate 62 is recessed at intervals along its length to form a plurality of protrusions 620 facing the second locking plate 64 . Two slits 624 are defined on two sides of each protrusion 620 in the first locking plate 62 . The first buckling plate 62 is bent downward along the length direction to the other side and then bent inward to form a resisting piece 626 . A strip-shaped protrusion 640 is formed at the center of the second locking plate 64 along its length and is bent outwards at the edge to enlarge the entrance 66 .

Each pivot piece 70 includes a piece-shaped body 71 , a blocking piece 72 protruding from an end of the body 71 away from the second locking plate 64 , and a restricting portion 74 disposed on a side of the body 71 . The limiting portion 74 is U-shaped, and includes two connecting pieces 740 connected to the main body 71 and a limiting piece 742 parallel to the main body 71 . The limiting portion 74 and the main body 71 form an opening 76 through which the buckle 46 passes. The main body 71 defines two fixing holes 710 on one side of the restricting portion 74 , and defines a through hole 712 close to the blocking piece 72 . The through hole 712 is a counterbore.

The buckle 46 is made of elastic material and is T-shaped, and includes a fixing piece 462 and a buckling piece 464 . A rivet post 4620 protrudes vertically from both ends of the fixing piece 462 . A buckle 4640 protrudes vertically from two long side edges of the buckle piece 464 respectively. The extension direction of the rivet post 4620 and the buckle 4640 is the same.

When assembling, the buckle pieces 464 of the two buckle pieces 46 pass through the openings 76 of the two pivot pieces 70 respectively, and the restricting portion 74 restricts the fixed pieces 462 of the buckle pieces 46 so that the rivet posts 4620 of the two buckle pieces 46 are aligned. To the fixing holes 710 of the two pivoting pieces 70 . Then, the rivet post 4620 is riveted into the fixing hole 710 , so that the two buckle parts 46 are fixed on the two pivot pieces 70 . Then the through holes 712 of the two pivoting pieces 70 are facing the fixing holes 540 of the two side walls 54 of the frame 50, and are fixed in the fixing holes 540 through the two through holes 712 by two rivets 80, so that the fixed frame 44 can pass through the two pivots. The rotating piece 70 rotates around the rivet 80 as an axis. The expansion card 30 is fixed on the main board 20, so that the main body 32 is electrically connected to the main board 20, the first positioning piece 340 of the I/O mask 34 abuts against the top plate 56 of the frame 50, and the second positioning piece 342 is installed in the conventional way In the limiting hole provided on the rear window 42 , each second positioning piece 342 faces a window 480 . Finally, the fixed frame 44 is rotated upwards, so that the top plate 56 and the second positioning piece 342 enter the accommodating space 65 of the fixed frame 44 through the entrance 66, the protrusion 620 and the pressing piece 626 press the second positioning piece 342, and the protrusion 640 presses against the second positioning piece 342. The top plate 56 is pressed so that the I/O shroud 34 is fixed to the rear window 42 . At the same time, the restricting portion 74 restricts the buckling piece 464 of the buckling member 46 , and the buckle 4640 of the fixing frame 44 is buckled in the slot 544 of the two side walls 54 of the frame 50 , so that the fixing frame 44 is fixed on the frame 50 .

When the fixing frame 44 is rotated downward, the stop piece 72 can be blocked by the protrusion 542 of the rear window 42 , so as to prevent the fixing frame 44 from excessively rotating downward and colliding with the rear window 42 to cause damage to the rear window 42 .

The housing of the electronic equipment of the present invention fixes the I/O mask 34 on the expansion card 30 to the rear window 42 of the housing through the fixing bracket 44, without using screws, and the fixing is convenient and simple.
