Description of the Invention: [Technology of the Invention] [0001] The present invention relates to a stent, and in particular to a stent for a PCI expansion card. [Prior Art] [〇〇〇2] A typical PCI expansion card consists of a board and a bracket. A mounting strip is provided on the bracket for securing the PCI expansion card to the chassis. The height of the PCI expansion card is the height of the bracket. Currently, the industry standardizes the installation height of two PCI expansion cards: standard PCI (PCI standard) expansion card installation 〇 height and small size PCi (pci Low Profile) expansion card installation height. The mounting height of a small-sized PCI expansion card is smaller than that of a standard pCI expansion card. PCI I expansion cards with standard PC I mounting height and PCI expansion cards with small PCI mounting height can only be plugged into standard PCI expansion slots and small PCI expansion slots. These two PCI expansion cards are not universal. It is not convenient to use.

The connecting bars 57 of the positioning member 500 are operated to compress the positioning member 500 from the upper and lower ends to the middle portion. It is received in the accommodating portion 31 of the accommodating member 300, and the ribs 561 on the two first extending portions 56 of the locating member 500 are aligned with the through holes 3131 of the two first side plates 313 of the accommodating portion 31 of the accommodating member 300. The connecting rods 57 are opened, so that the protrusions 561 of the two first extending portions 56 of the positioning member 500 respectively pass through the through holes 3131 of the receiving portion 31 and the two first through holes 1112 on the left side of the two folded plates 111 of the fixing frame 11 , thereby The positioning member 500, the receiving member 300 and the bracket 100 are combined together. At this time, the PCI expansion card 099123824 Form No. A0101 Page 7 / Total 24 Page 0992041953-0 201206317 The bracket is at the standard mounting height, that is, the receiving part 3G () The front plate 311 of the portion 31 abuts against the connecting plate 112 of the fixing frame of the bracket 100, and the supporting plate 112 The opening 115 of the holder 11 is unshielded in its length direction and is suitable for mounting a standard height PCI expansion card. The positioning member 500 can be rotated about a shaft 561 that cooperates with the holder 11. [0013] [0014] Please also refer to FIG. 5, when the PCI expansion card bracket needs to be changed from the standard installation height to the small installation height, as long as the connecting strip 57 of the positioning member 5GQ is operated, the clamping member 500 is compressed from the upper and lower ends to the middle. The shank 561 of the two first extending portions 56 is disengaged from the first through hole 1112 of the fixing frame ,1, and then the accommodating member 300 is moved to the right until the two through holes 3131 of the accommodating member 3 (10) correspond to the two fixing frames 11 respectively. Two second through holes 1114 of the folded plate U1. Then, the connecting strip 57 is loosened, so that the two protruding portions 561 of the two first extending portions of the positioning member 5 are respectively passed through the through hole 3131 of the receiving portion 31 and the second through holes 1114 of the fixing frame, so that the receiving member The front plate 311 of the 300 covers the left end of the opening 115 of the fixing frame u and the second side plate 3丨5 of the right side abuts the left end of the blocking piece 114 of the fixing frame 1丨. At this time, the PCI expansion card bracket - in a small size Installation height, suitable for installing PCI expansion cards of small height. ::':....... Please refer to Figure 6, which is a schematic diagram of the standard PCI expansion card 7〇. The standard PCI expansion card 70 includes An elongated plate body 71, a longitudinally extending pivot piece 73 extending outward from the long side of the plate body 71, and a bracket 75 fixed to a short side of the plate body 71. The bracket 75 includes a square first The sheet body mi, the square-shaped second sheet vertically bent from the side of the first sheet body 751-side, and the square-shaped third sheet body 75 5 extending from the other end portion of the first sheet body 751. A central through slot 7512 is defined in the middle of the body 751, and the length of the through slot 7512 is equivalent to the length of the opening 115 of the fixed frame. The 099123824 form number A0101 Page 8 of 24 0992041953-0 201206317 The middle of the outer end of the first body 753 has an n-shaped notch 7532. The width of the third piece 755 is smaller than that of the first piece 751. 4 and FIG. 7, when installing the standard Μ! expansion card ^ to the standard two-degree PCI expansion card bracket, 'first rotate the positioning member out of the accommodating portion 31 of the accommodating member 300' to make the standard ρπ expansion card 7 () splicing # 73 The second slot π3 of the bracket 75 of the standard pci expansion card 7A is pulled in the through slot 1318 of the carrier 131 7 of the card holder 13 of the cassette holder 100, and the second side of the housing portion 31 of the holder is moved. The two side plates 315 abut against the right side of the second side plate 315, and the second piece 75 5 is pressed against the flaps 131 of the top plate 13. At this time, the through groove 7 512 is directly opposite the frame 1 The opening 115 of the fixing frame 11 of the crucible. Then, the positioning member 500 is rotated to screw the positioning member 500 into the receiving portion 31, and the protruding post 591 outside the second extending portion 59 of the positioning member 500 is inserted into the second piece 753. The second piece 753 is positioned in the notch 7532 so that the standard pc! expansion card 70 is fixed to the bracket. The protrusion 581 of the second extension 58 abuts the receiving part of the housing 3 0 0 The inner surface of the side plate 313 prevents the positioning member 5 from rebounding. [〇〇16] Please refer to Fig. 8, which shows a small-sized PCI expansion card 8〇. This small-size PCI expansion card The 80 also includes a plate body 81, a pivoting piece 83 and a bracket 85. The bracket 85 includes a square first body 851, and a square second piece 853 vertically bent from the side of the first piece 851. And a square third piece 855 extending from a middle portion of the other end of the first sheet body 851. A central through groove 8512 is defined in a middle portion of the first piece 851, and the length of the through groove 8512 is equivalent to the size of the opening 1141 of the blocking piece 114 of the bracket 11 of the bracket. The difference between the small-sized PCI expansion card 80 and the standard PCI expansion card 70 is that the size of the plate body 81 and the bracket 85 are smaller than those of the plate body η and the bracket 75, respectively. The middle of the lower end of the second body 853 has a shape of 099123824 Form No. A0101 Page 9 / 24 pages 0992041953-0 201206317 Notch 8532 〇 [0017] Please refer to FIG. 9 , a method of installing such a small size PCI expansion card 80 Similar to the method of installing the standard PCI expansion card 70, the difference is that when the PCI expansion card bracket is at a small mounting height, the stud 601 of the fourth extension 60 of the positioning member 500 passes through the notch 8532 and positions the second piece. 853.
