Drive cage assembly

A combination comprising:

• a drive cage assembly and a data storage device therein;
• said drive cage assembly including a cage, a securing plate and a discrete coupling piece;
• said drive cage defining a base wall with upper and lower walls respectively extending horizontally from upper and lower edges thereof;
• a side opening formed in the cage opposite to said base;
• a plurality of posts formed on opposite surfaces of the base and the securing plate;
• the securing plate positioned around the side opening and engaged with the upper and lower walls;
• said discrete coupling piece releasably fixing the drive cage and the securing plate together;
• and
• the data storage device positioned between the base wall and the securing plate with thereof side holes respectively receiving the corresponding posts therein;
• wherein
• the discrete coupling piece includes means for preventing disengagement between the securing plate and the cage in a transverse direction parallel to an extending direction of said posts.

A method for assembling a data storage device into a cage, comprising the steps of:

• A. providing a cage including a base wall with upper and lower walls extending by two sides thereof and a side opening opposite to said base wall;
• B. providing a plurality of posts on an inner surface of the base wall;
• C. installing a coupling piece to the upper wall of the cage;
• D. inserting a data storage device into the cage between the upper and lower walls, in a transverse direction, with holes of the data storage device receiving the corresponding posts, respectively;
• E. attaching a securing plate to the cage around said side opening, along the same transverse direction, with thereof a plurality of posts received within the corresponding holes in the data storage device;
• and
• F. latching the securing plate to the cage by said coupling piece for preventing the securing plate from being detached from the cage in a direction opposite to said transverse direction, wherein the coupling piece extends across a slot of the upper wall of the cage and then engages with the securing plate.
