The securing protrusion 321 of the part 32 is deeper into the card slot 3 of the hard disk 2. When the hard disk carrier 20 moves from the release position to a locking position, the locking protrusions 321 remain locked in the pressed protrusions 322 under the pressure of the first vertical wall 12 and the second vertical wall 13 respectively. The card slot 3 of the hard disk 2. In this way, the movement of the hard disk 2 in the positive and negative Z-axis is restricted by the securing protrusions 321, so that the hard disk 2 is fixed to the hard disk carrier 20. Therefore, the hard disk 2 can be fixed to the hard disk carrier 20 without screwing, which saves the purchase cost of screws and improves the convenience of assembling the hard disk 2 on the hard disk carrier 20.

On the other hand, when the hard disk carrier 20 is in the clamping position, the movement of the hard disk carrier 20 in the positive and negative Y-axis is restricted by the first vertical wall 12 and the second vertical wall 13. In addition, in the state where the hard disk carrier 20 is in the clamping position, the neck 42 of the buckle 40 is located at the narrow part 2112 of the buckle hole 211, and the bottom 21 of the hard disk carrier 20 is located on the buckle 40 Between the head 41 and the carrier 11 of the tray 10. More specifically, the bottom 21 of the hard disk carrier 20 is located between the head 41 and the body 43 of the fastener 40. Thereby, the head 41 and the body 43 of the buckle 40 restrict the movement of the hard disk carrier 20 in the positive and negative Z-axis.

The curved surface 3221 of the pressed protrusion 322 can provide a guiding effect, so that the hard disk carrier 20 can slide smoothly.

In this embodiment, the securing protrusions 321 are not limited to the two through holes 221 of the first side portion 22 and the two through holes 231 of the second side portion 23 when they are not subjected to external force. In other embodiments, the fixing protrusions may not penetrate the two through holes on the first side and the two through holes on the second side when they are not subjected to external force. In this configuration, before the hard disk carrier with the hard disk has been moved from the release position to the securing position, the latching bumps have not been inserted into the hard disk, and the hard disk carrier is moved on the hard disk carrier. After reaching the fixing position, the fixing protrusions are pressed into the hard disk only after being pressed by the first vertical wall and the second vertical wall.

Then, the stopper 50 is rotated to rotate the stopper 50 from the initial position to the stop position. When the stopper 50 is at the stop position, the different sides of the stopper 50 abut against the two stop surfaces 1111, 1112 of the stop portion 111 of the carrier board 11 (as shown in FIG. 2), and the first The positioning protrusion 252 and the second positioning protrusion 253 are respectively located in the first positioning hole 52 and the second positioning hole 53. From FIG. 2, the stop surface 1111 of the stop part 111 faces the negative X-axis, so the setting of the stop part 50 against the stop surface 1111 of the stop part 111 restricts the hard disk carrier 20 in the positive direction. Movement on the X axis. In addition, the combination of the narrow portion 2112 of the buckle hole 211 and the neck 42 of the buckle 40 restricts the movement of the hard disk carrier 20 in the negative X axis.

If the hard disk carrier 20 is to be separated from the tray 10, the stopper 50 is rotated from the stop position to the initial position, so that the stopper 50 is separated from the stop portion 111 of the carrier board 11. Then, the hard disk carrier 20 is slid along the positive X axis, so that the necks 42 of the fasteners 40 are located at the wide portions 2111 of the fastener holes 211, respectively. At this time, the hard disk carrier 20 can be taken along the positive Z axis, and the hard disk carrier 20 can be separated from the tray 10. Then, afterwards, just slightly move these flexible fasteners 30 to make the locking protrusion 321 separate from the slot 3 of the hard disk 2, and the hard disk 2 can be separated from the hard disk carrier 20.

In this embodiment, by the arrangement of the guide groove 51 of the stopper 50 and the guide protrusion 251 of the front vertical portion 25, the rotation angle of the stopper 50 can be restricted to avoid excessive rotation of the stopper 50. In this embodiment, the front vertical portion 25 has a guiding protrusion 251, and the stopper 50 has a guiding groove 51, which is not intended to limit the present invention. In other embodiments, the stopper may have a guiding groove, and the front vertical portion has a guiding protrusion. Or, the vertical plate part may have no guiding protrusion, and the stopper may have an infinite slot.

In addition, when the stopper 50 rotates from the initial position to the stop position, the stopper 50 will abut the stop surface 1112 of the stopper 111, so the stopper surface 1112 of the stopper 111 can ensure the stopper. 50 can not continue to rotate after rotating to the stop position.

Furthermore, the combination of the first positioning protrusion 252, the second positioning protrusion 253, the first positioning hole 52, the second positioning hole 53, and the relief notch 54 helps the stopper 50 to be positioned at the initial position or stop. To reduce the probability of unexpected rotation of the stopper 50 at the initial position or the stop position.

In this embodiment, in addition to the effect of positioning the stopper 50, the giving way gap 54 also has the effect of giving way to the second positioning protrusion 253, so as to prevent the stopper 50 from rotating to the initial position. The positioning protrusion 253 and the stopper 50 are in a state of interference.

However, the arrangement that the front vertical portion 25 has a first positioning protrusion 252 and a second positioning protrusion 253, and the stopper 50 has a first positioning hole 52, a second positioning hole 53, and a recess 54 are not intended to limit the present invention. invention. In other embodiments, the front vertical portion may be free of the first positioning protrusion and the second positioning protrusion, and the stopper may be free of the first positioning hole, the second positioning hole and the recession.

On the other hand, the number of flexible card firmware 30 is not limited to four. In other embodiments, the hard disk carrier assembly may have only two elastic fasteners closer to the stopper, or only two elastic fasteners farther from the stopper.

According to the hard disk carrier assembly disclosed in the above embodiment, two flexible fasteners are respectively arranged on the first side and the second side of the hard disk carrier, and the first side and the second side of the hard disk carrier The parts are respectively adjacent to the first vertical wall and the second vertical wall of the tray, so that when the hard disk carrier slides to the clamping position, the two elastic fasteners are respectively pressed by the first vertical wall and the second vertical wall, and the On the hard drive. Therefore, the hard disk can be fixed to the hard disk carrier without screwing, which saves the purchase cost of screws and improves the convenience of assembling the hard disk on the hard disk carrier.
