Mounting apparatus for data storage device

1. A mounting apparatus for mounting a data storage device defining a screw hole in a side of the data storage device, the mounting apparatus comprising:

a bracket to receive the data storage device, the bracket defining an opening for the data storage device passing therethrough to enter into or retract out of the bracket;

a holder attached to the bracket and adjacent to the opening;

wherein the holder is movable between a first position where the holder extends to the opening to block the data storage device, and a second position where the holder departs from the opening to enable the data storage device enter into or retract out of the bracket through the opening;

wherein the holder comprises a resilient arm and an operating member fixed to the resilient arm, the resilient arm comprises a first end fixed to the bracket, and a second end connected to the operating member, the operating member is biased by the resilient arm to block the opening of the bracket when the holder is in the first position;

wherein the holder further comprises an abutting member fixed to the resilient arm and adjacent to the operating member, the abutting member extends into the bracket and contacts the data storage device when the holder is in the first position; and

wherein the abutting member comprises a connecting bar and an abutting bar, the connecting bar comprises a first end fixed to the resilient arm, the abutting bar extends from a second end of the connecting bar and forms an abutting protrusion to engage into the screw hole of the data storage device.

2. The mounting apparatus of claim 1 , wherein the operating member forms a blocking surface facing the opening of the bracket in response to the holder at the first position, and a curved guiding surface opposite to the blocking surface, the holder is urged to move towards the second position in response to the data storage device sliding along the guiding surface to enter into the bracket.

3. The mounting apparatus of claim 1 , further comprising a resilient member, wherein the bracket comprises an end plate opposite to the opening, the resilient member is attached to the end plate and urges the data storage device towards the opening in response to the data storage device being received in the bracket.

4. The mounting apparatus of claim 3 , further comprising a fastener fixing the resilient member to the end plate.

5. The mounting apparatus of claim 3 , wherein the resilient member is a coil spring and comprises a connecting end, the fastener is a screw passing through the connecting end and engaging with the bracket to fix the connecting end of the resilient member to the end plate of the bracket.

6. The mounting apparatus of claim 4 , wherein a fastening post extends from the end plate and defines a screw hole, the fastener is engaged in the screw hole of the fastening post.

7. An assembly comprising:

a data storage device comprising two opposite sidewalls, a front end, and a rear end opposite to the front end;

a bracket to receive the data storage device, and the bracket defining an opening for the data storage device entering into or retracting out of the bracket;

a holder movably mounted to the bracket and abutting against the front end of the data storage device at the opening, thereby preventing the data storage device from retracting out of bracket through the opening;

wherein the data storage device is operable to retract out of the bracket in response to the holder disengaging from the data storage device;

wherein the bracket comprises a base and a cover secured to the base, the base comprises a bottom plate opposite to the cover, a first side plate and a second side plate extending from opposite sides of the bottom plate, and an end plate opposite to the opening;

wherein the holder comprises a resilient arm and an operating member fixed to the resilient arm, the resilient arm is fixed to the first sidewall of the bracket and adjacent to the opening, and the operating member extends to the opening of the bracket to abut against the front end of the data storage device;

wherein the holder further comprises an abutting member fixed to the resilient arm, the base of the bracket, the resilient arm, and the abutting member are made of electrically conductive material, the abutting member extends into the bracket through the first side plate to engage with the data storage device; and

wherein the abutting member comprises a connecting bar and an abutting bar, the connecting bar comprises a first end fixed to the resilient arm; the abutting bar extends from a second end of the connecting bar, and forms an abutting protrusion engaging in a screw hole defined in a corresponding sidewall of the data storage device.

8. The assembly of claim 7 , further comprising a resilient member attached to the end plate of the bracket, to resist against the rear end of the data storage device in response to the data storage device being received in the bracket.

9. The assembly of claim 8 , wherein the resilient member is a coil spring, and comprises a first end fixed to the end plate of the bracket and a second end extending towards the opening to resist against the rear end of the data storage device.

10. The assembly of claim 7 , wherein the operating member comprises a blocking surface facing the opening and a curved guiding surface opposite to the blocking surface; the operating member is urged to move away from the opening in response to the data storage device sliding along the guiding surface with the rear end to enter into the bracket; and the blocking surface abuts against the front end of the data storage device in response to the data storage device being received in the bracket.
