[0005] Compared with the prior art, the expansion card fixing device is configured to receive the expansion card by the limiting slot and the recess, and the expansion card is buckled by the pressing arm. Install the expansion card. 099126706 Form No. A0101 Page 4 of 17 0992046850-0 201208532 [Embodiment] [〇〇〇6] Referring to Figure 1, the expansion card fixing device of the present invention can be used to fix an expansion card 30. The expansion card 30 includes a main body 31 and a blocking piece 32 fixed to the main body 31. The main body 31 includes a side edge 311 and a plug portion 313 opposite to the blocking piece 32. The blocking piece 32 includes a stopper 323 and a flange 321 connected to the stopper 323. In an embodiment, the expansion card 30 can be a graphics card, a network card, or a sound card. [0007] One embodiment of the expansion card fixing device includes a chassis 40, a main f) board 50, And a fixed frame 1〇〇. The chassis 40 includes a bottom plate (not shown) and four side walls 41, 42, 43, 44 disposed on four edges of the bottom plate. The side wall 42 defines an opening 423. A lower edge of the opening 423 extends inwardly to support the flange 321 . The side wall 43 is provided with three limiting holes 432, two first openings 43 and two second openings 433. Each of the first openings 431 is between each of the two seating holes 432 and is arranged in a line. The Qth second opening 433 is located below the first opening 431 and the limiting hole 432. In one embodiment, the side walls 41, 42, 43, 44 are substantially perpendicular to the bottom plate' and the side walls 41, 44 are parallel to one another and generally perpendicular to the side walls 42, 43. The motherboard 50 is mounted on a bottom plate (not shown) of the chassis 40. The motherboard 50 is provided with a slot 5〇1 for receiving the plug-in portion of the expansion card 30. 313. [0010] Referring to FIG. 2 to FIG. 3, the fixing frame 1 includes an insertion portion 1 and a pressing portion 20. 099126706 Form No. A0101 Page 5 of 17 0992046850-0 201208532 [0011] The insertion portion 10 includes a patch panel 1 and four flat plates 112, 113, 114 extending along four sides of the patch panel 111. 115. The plurality of limiting plates 1113 are formed between the two limiting plates 111 3 . The second edge of the flat plate 11 is provided with two second hooks 1131. The rear edge of the flat plate 4 is provided with two first hooks 1141 and three limiting pieces 1143. Each of the first hooks 1141 is between every two limit pieces 1143 and each of the limit pieces 1143 is arranged in a line with each of the first hooks 1141. The patch panel 111 and the four flat plates 112, 113, 114, 115 form a receiving space for receiving the fan. ...........: [0012] The pressing portion 20 includes a top plate 211, a plurality of elastic pressing arms 23 extending obliquely from the top plate 211, and two along the top plate 21:1. The side plates 213, 215 extending perpendicularly downward from the edge, the side plates 213, 21 5 are parallel and in contact with the side faces 113, 115 of the insertion portion 10, respectively. A partition 25 is disposed between the two adjacent pressing arms 23. The pressing arm 23 includes an elastic portion 231 , a buckle life $33 connected to the end of the elastic portion 231 , and two convex portions extending along the elastic portion 231 and the two sides of the locking portion 233 . Sides 235, 237. The two ribs 235 and 237 and the elastic portion 231 and the locking portion 233 form a recess 239. The recess 239 and the limiting slot 1115 are in the same extending direction. The first reinforcing rib 52 is disposed at an intersection of the elastic portion 231 and the top plate 211. The first reinforcing rib 52 is curved in a shape that is not in contact with the top plate 211 and the elastic portion 231. A third reinforcing rib 51 connecting the elastic portion 231 and the top plate 211 is disposed between the two opposite first reinforcing ribs 52. The hooking portion 233 is formed to be bent inward from the end of the elastic portion 231. The latching portion 233 includes a connecting portion 2331 and a stopping portion 2333 which are connected to the elastic portion 231 at an angle to the 099126706 form number A0101, page 6 / page 17 0992046850-0 201208532. Two parallel reinforcing ribs 60 are protruded from the connecting portion "" of the elastic portion 231 and the locking portion 233, respectively. Due to the addition of the first reinforcing rib 52 and the second reinforcing rib 60, the plastic deformation of the pressing arm 23 is greatly reduced, thereby greatly improving the impact resistance and strength of the expansion card fixing device. [0013] Continuing to refer to FIG. 4, during installation, the first card fishing rod 41 of the fixing frame 100 is engaged with the first opening 431 of the casing 4, and the second card is engaged. 11 31 is engaged with the second opening 4.33. The limiting piece 114 3 is inserted into the limiting hole 432 to fix the fixing frame 1 to the side wall 43i of the casing 4 . Inserting the side edge 311 of the expansion card 30 into the recess 239 of the elastic portion 231 to force the expansion card 30 to slide the side edge 311 downward along the groove 239. The elastic portion 231 is elastically deformed by the side edge 311 to bias the pressing arm 23 toward the side wall 43 , and the side edge 311 slides into the limiting groove 1115 . When the insertion portion 313 of the expansion card 30 is inserted into the limiting slot 501, the flange 321 abuts against the support piece 421, and the side 311 passes over the elastic portion 231. The pressing portion 23 is elastically restored, and the locking portion 233 is caught on the upper edge of the expansion card 30 to block the expansion card 30 from sliding upward, and the folding edge 321 is fixed to the flange 321 by screws or the like. The pusher piece 421 is attached to fix the expansion card. In summary, the disc of the present invention has met the requirements of the invention patent 爰 提出 filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and equivalent modifications or variations made by those skilled in the art of the present invention should be included in the following patent application form 099126706.
