1. Technical Field
The disclosure relates to a hard disk drive.
2. Description of Related Art
A hard disk drive includes a housing module and a hard disk module mounted in the housing module. If the hard disk module needs to be replaced, a new housing module is needed to accommodate the new hard disk module, which increases the cost, and even wastes the old housing module.
Many aspects of the present embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present embodiments. Moreover, in the drawings, all the views are schematic, and like reference numerals designate corresponding parts throughout the several views.
The disclosure, including the accompanying drawings, is illustrated by way of examples and not by way of limitation. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
Referring to
The housing module 10 includes a bracket 12, a connecting board 14 mounted in the bracket 12. The bracket 12 is divided into first and second receiving rooms by the connecting board 14. The first receiving room 120 which is located adjacent to the front side of the bracket 12 is smaller. Sidewalls of the first receiving room 120 define a number of through holes 122. The second receiving room (not labeled) which is located adjacent to the back side of the bracket 12 is larger, and configured to accommodate a power supply and other elements to execute the function of the hard disk drive.
Opposite ends of the connecting board 14 are mounted to opposite sides of the bracket 12. A set of first type of connectors 142 extend into the first receiving room 120 from the connecting board 14. A set of second type of connectors 144 extend into the first receiving room 120 from the connecting board 14.
The 3.5-inch hard disk module 20 includes a number of hard disk devices 22 and a cage 24 for receiving the hard disk devices 22. Sidewalls of the cage 24 define a number of fastening holes 242. A circuit board 26 is detachably mounted to the back side of the cage 24 and is electrically connected to the hard disk devices 22. A number of connectors 262, corresponding to the first type of connectors 142 of the housing module 10, protrude from the circuit board 26.
Similarly, the 2.5-inch hard disk module 20a includes a number of hard disk devices, a cage, and a circuit board having a number of connectors corresponding to the second type of connectors 144 of the housing module 10.
Referring to
In replacement of the 3.5-inch hard disk module 20 with the 2.5-inch hard disk module 20a, the fasteners 30 are released, then, the 3.5-inch hard disk module 20 is removed from the housing module 10. Thereafter, the 2.5-inch hard disk module 20a is mounted to the housing module 10, with the second type of connectors 144 of the housing module 10 connected to the connectors of the 2.5-inch hard disk module 20a, and the first type of connectors 142 abutting against the circuit board of the 2.5-inch hard disk module 20a.
It is believed that the present embodiments and their advantages will be understood from the foregoing description, and they will be apparent that various changes may be made thereto without departing from the spirit and scope of the description or sacrificing all of their material advantages, the examples hereinbefore described merely being exemplary embodiment.
