[embodiment]
Please refer to Fig. 1, the better embodiment expansion card fixer of the present utility model single expansion board 30 that is used to lock, it comprises that a pedestal 10 and a pair of rotation are fixed on the fixture 20 on this pedestal 10.
Please continue with reference to Fig. 2 to Fig. 6, this pedestal 10 comprises a rear wall 12 and a sidewall 14 that is connected with rear wall 12, these rear wall 12 levels have been bent to form a back up pad 13, on the bottom of this rear wall 12 and this back up pad 13, offer some L shaped expansion draw-in grooves 124, on this back up pad 13, expand draw-in groove 124 1 ends and all convex with two positioning convex column 132 near each, 134, all inside dashing is provided with two carrying tablets 125 perpendicular to this rear wall 12 above being positioned at each expansion draw-in groove 124 on the rear wall 12 of this pedestal 10, each carrying tablet 125 top offers a pivoting hole 127, each carrying tablet 125 bottom offers a location division 129 (this location division is a pilot hole in the present embodiment, and this location division can also be a salient point).Be provided with a location-plate 16 that is fixed on the sidewall 14 of this pedestal 10 on the opposite of expanding draw-in groove 124, this location-plate 16 offers some strip flutings 161, each both sides, 161 top of slotting also offers a guide groove 162 respectively, on the side plate 164 of each 161 both sides of slotting of end of each guide groove 162, all offer a pivoting hole 165 respectively, on the side plate 164 of each 161 both sides of slotting and the below that is positioned at this pivoting hole 165 all is provided with a location division 166 (this location division is a pilot hole in the present embodiment, and this location division can also be a salient point).
This two fixture 20 rotates respectively and is installed on these pedestal 10 rear walls 12 and this location-plate 16.Each fixture 20 comprises that a rotating shaft 21 and that is positioned at the top is positioned at the pressure section 22 of bottom, be equipped with a holding division 24 (this holding division is a salient point in the present embodiment, and this holding division can also be a pilot hole) in each fixture 20 both sides and near pressure section 22 places.
This expansion board 30 comprises a circuit board 31 and is installed in the catch 32 of the correspondence expansion draw-in groove 124 of these circuit board 31 1 ends, these catch 32 top levels bend an installation portion 321, and this installation portion 321 offers the breach 322 and a breach 324 that vertically is provided with of a horizontally set.
Please continue with reference to Fig. 4 and Fig. 6, during assembling, this keeper 20 be rotated between this two carrying tablet 125 thereby rotating shaft 21 correspondences of a fixture 20 are fastened in the pivoting hole 127 on two carrying tablets 125 on these pedestal 10 rear walls 12; Again the rotating shaft 21 of another fixture 20 is fastened in along guide groove 162 correspondences in the pivoting hole 165 on the side plate 164 of fluting 161 both sides, so that this fixture 20 pivots in the fluting 161 that is installed in location-plate 16 and be unlikely and come off.
Please continue with reference to Fig. 7 and Fig. 8, when this expansion board 30 is installed, aims at the slot (not shown) of motherboard and insert this expansion board 30 downwards, the projection 132,134 on this back up pad 13 passes the breach 322,324 of the catch 32 on this expansion board 30 respectively.Simultaneously, circuit board 31 1 ends of this expansion board 30 move downward along the fluting 161 of this location-plate 16.When the pin of this expansion board 30 (indicating) tightly inserts in the slot of motherboard, when the installation portion 321 of the catch 32 of this expansion board 30 is close to the back up pad 13 of these pedestal 10 rear walls 12, rotate the fixture 20 that is installed between two carrying tablets 125 and make the bottom surface of the pressure section 22 of this fixture 20 compress the installation portion 321 of this catch 32, rotate the fixture 20 that is installed on the location-plate 16 simultaneously and make the bottom surface of the pressure section 22 of this fixture 20 compress the apical margin of this circuit board 31.When two holding divisions 24 on this two fixture 20 snapped in location division 129 on two carrying tablets 125 and the location division 166 on the biside plate 164 respectively, this two fixture 20 was fixed on this expansion board 30 on this pedestal 10 jointly.
