1. Technical Field
The present disclosure relates to a casing for receiving a hard disk drive (HDD).
2. Description of Related Art
HDDs mounted in servers are easily affected by electromagnetic interference (EMI). However, conventional casings for HDDs do not help much in reducing EMI on the HDDs. Therefore, there is room for improvement in the art.
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 example 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 casing 10 is made of metal material and includes a top wall 12, a bottom wall 14, two sidewalls 16 connected between the top and bottom walls 12 and 14, and an end wall 18 connected between the sidewalls 16 and the top and bottom walls 12 and 14.
A plurality of metal bars 120 protrudes from an inner surface of the top wall 12. The metal bars 120 are connected substantially perpendicularly between the sidewalls 16 to reduce electromagnetic interference (EMI) on the HDD 20.
The HDD 20 is received in the casing 10. A distance, such as 1.8 millimeters (mm), is kept between the HDD 20 and the metal bars 120 for conveniently installing the HDD 20.
In this embodiment, the HDD has a height of about 25 mm. A thickness of each of the top wall 12, the bottom wall 14, the sidewalls 16, and the end wall 18 is about 1.2 mm. The casing 10 is about 30.4 mm in height, about 186 mm in length, and about 107.4 mm in width. A thickness of each metal bar 120 and a width of each metal bar 120 are both about 1.2 mm. As shown in
In other embodiments, the metal bars 120 can protrude from the bottom wall 14 or the sidewalls 16.
It is believed that the present embodiments and their advantages will be understood from the foregoing description, and 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 embodiments.
