4A-4D are schematic diagrams showing the assembly process of fixing the adapter card to the riser card fixing device. As shown in FIG. 4A, when the riser card 1300 is not supported and fixed on the riser card fixing device 1200, the body 1222 of the riser card fixing device 1200 is randomly connected to the side wall 1110 of the casing 1100 (shown in FIG. 2). Clip an angle. Then, referring to FIG. 2 and FIG. 4B, when the adapter card 1300 is to be fixed to the riser card fixing device 1200, the assembler first bears the side of the riser card 1300 with the golden finger (not labeled) on the machine. The two sides of the side wall 1120 of the case 1100 are on the carrying portion 1224 of the latching member 1220 of the riser card fixing device 1200, and the gold finger is inclined to the first slot 1410.

Then, as shown in FIG. 4C, the assembler can apply the force to the load-bearing portion 1224 by the weight of the load-carrying member 1224, thereby driving the body 1222 of the buckle member 1220 to assemble the shaft 1228 as a rotation axis. The bearing portion 1224 is rotated relative to the fixed seat 1210 toward the side wall 1110 of the casing 1100, and the gold finger of the riser card 1300 reclining the first slot 1410 is rotated with respect to the fixed portion 1210 of the carrying portion 1224. The home appliance is inserted into the first slot 1410 of the circuit board 1400 as shown in FIGS. 1 and 4D. In particular, the hook 1226 penetrates and snaps into the opening 1310 of the riser card 1300 as the body 1222 rotates to fix the relative position of the riser card 1300 and the circuit board 1400, so that the riser card 1300 is firmly Plugged into the first slot 1410.

Incidentally, the hook 1226 can further have a recess 1226a, and when the recess 1226a fixes the riser card 1300 by the hook 1226, the recess 1226a can be fastened to the edge of the opening 1310, so that the adapter card 1300 and The snap member 1220 is more securely fixed.

After the riser card 1300 is firmly fixed on the riser card fixture 1200, a card 1500 can be inserted into the second slot 1320 of the riser card 1300 to enable the card 1500 to be transferred. The card 1300 is electrically connected to the circuit board 1400, as shown in FIG.

Then, if it is not necessary to use the riser card 1300, the reverse card 1300 can be easily removed from the riser card fixing device 1200 by simply reverse the above steps. As shown in FIGS. 1 and 4D, the assembler can manually grip the side of the riser card 1300 on which the second slot 1320 is disposed, and then apply an upward force to pull the gold finger of the riser card 1300 away from the circuit board 1400. The first slot 1410. Next, as shown in FIG. 4C, when the riser card 1300 is pulled out of the first slot 1410, the riser card 1300 is slightly rotated, so that the side on which the second slot 1320 is disposed is relatively far from the side wall 1110. At this time, the limit of the adapter card 1300 by the hook 1226 is released, as shown in FIG. 4B. Thereafter, the riser card 1300 is moved away from the riser card fixture 1200, as shown in Figures 2 and 4A.

6 is a schematic diagram of another embodiment of an electronic device. Referring to FIG. 6 , the electronic device 1000 may further include a plurality of springs 1600 , and the springs 1600 may be disposed between one end of the body 1222 of the latching member 1220 and the sidewall 1110 (in the embodiment, the spring 1600 One end is connected to the side wall 1110, and the other end is connected to the carrying portion 1224 of the latching member 1220. When the latching member 1220 is not engaged with the riser card 1300, the body 1222 is inclined with respect to the side wall 1110 to raise the load. The portion 1224 allows the assembler to more conveniently place the riser card 1300 on the carrier 1224. The type of the spring is determined depending on the installation position. For example, the spring connected to the carrier portion 1224 is a tension spring, and the spring disposed at the other end of the body 1222 not provided with the carrier portion 1224 is a telescopic spring. The spring can be selected to correspond to one end of the body 1222.

Compared with the conventional use, the use of the riser card fixing device of the above embodiment does not require the use of a hand tool to lock or disassemble the screw, which can save man-hours and manpower. It is also known for assembly personnel to have assembly convenience.

In summary, in the adapter card fixing device of the present invention and the electronic device using the adapter card fixing device, when the assembler places the adapter card on the carrying portion of the card fastener, the adapter card itself The weight can rotate the bearing portion of the fastening component of the adapter card fixing device toward the side wall of the casing relative to the fixing seat, and the hook of the fastening component buckles the opening of the adapter card to stabilize the adapter card The ground is plugged into the slot of the board. During the assembly process, the assembler does not need to use any hand tools and screws, so the assembly time is saved compared to the conventional one. Moreover, the adapter card can be easily inserted into or removed from the slot by simply inserting and pulling, so that assembly convenience is more convenient than conventional.
