The present disclosure relates to a chassis with a fastening apparatus in a housing.
FIG. 1 and FIG. 2 illustrate an exemplary embodiment of a chassis. The chassis comprises a housing 10, a plurality of hard disk drives 50 mounted in the housing 10, and a plurality of fastening apparatus 40. The housing 10 comprises a bottom plate 11, a top plate 13, a plurality of backplanes 15 mounted between the bottom plate 11 and the top plate 13, and two side plates 17 parallel to the backplanes 15. All of the plurality of backplanes 15 are parallel to each other.
Referring to FIG. 3, the bottom plate 11 defines a plurality of notches 111 between the backplanes 15, and between the backplane 15 and side plate 17. The plurality of notches 111 are parallel to and spaced from each other. Each backplane 15 comprises a connecting plate 151 and a fixing plate 153 parallel to the bottom plate 11. A middle portion of fixing plate 153 is coupled to a top end of the connecting plate 151. Connectors 1511 are coupled to two sides of the connecting plate 151, each connector 1511 being located beside a row of the notches 111. Two sides of each fixing plate 153 define a plurality of arcuate slots 1531 above the notches 111. An inside of each side plate 17 defines a plurality of openings 171 which are spaced from each other. A plurality of raised pillars 173 spaced from each other protrude from a top of each side plate 17.
Referring to FIGS. 4-6, one end of each hard disk drive 50 defines an opening 51, and the other end of the hard disk drive 50 has an electrical connector 53. A raised protrusion 55 protrudes from the top of the hard disk drive 50, which is adjacent to the opening 51. A raised pillar 57 protrudes from the top of the hard disk drive 50, which is adjacent to the opening 51. A plurality of positioning protrusion 59 protrudes from a bottom end of the hard disk drive 50.
Referring to FIGS. 5-7, the fastening apparatus 40 comprises a connecting member 41 and a fastening member 43. The connecting member 41 comprises a locking portion 411, a base plate 413 coupled to the top of the locking portion 411, and two stopping portions 415 which are coupled to a bottom end of the base plate 413 and located at two sides of the locking portion 411. Each stopping portion 415 comprises two flexible arms 4151 opposite to each other. The locking portion 411 comprises a connecting post 4111. Two locking protrusions 4113 protrude from two sides of the connecting post 4111. A middle portion of the base plate 15 defines a mounting hole 4131 which runs through a bottom end and the two sides of the connecting post 4111. A slide guide portion 4135 protrudes from an inside wall of a middle portion of the mounting hole 4131. A raised portion 4137 protrudes from an inside wall of a lower portion of the mounting hole 4131. Each side of the base plate 413 defines a locking hole 4139 opposite the two locking protrusions 4113. Two slide guide grooves 4138 are formed at the two sides of the mounting hole 4131.
The fastening member 43 comprises a pressing portion 431 and a resisting portion 433 coupled to the pressing portion 431. In at least one embodiment, the resisting portion 433 can be a cylindrical post. The resisting portion 433 comprises a post 4331, an urging portion 4333, and a neck portion 4335 coupled between the post 4331 and the urging portion 4333. The diameter of the neck portion 4335 is less than the diameter of the post 4331 and of the urging portion 4333. A sloping portion 4336 is formed at a connection between the post 4331 and the neck portion 4335. Two guide strips 4337 protrude from two sides of the post 4331. The urging portion 4333 defines a concave dent 4339 in an outside wall thereof.
Referring to FIG. 1 and FIG. 6, in assembly of the chassis, the connectors 53 of the hard disk drives 50 are inserted into the connectors 1511 of the backplanes 15. The raised protrusion 55 of each hard disk drive 50 is locked in the slots 1531 of the backplane 15, and the positioning protrusion 59 of each hard disk drive 50 are locked in the notches 111 of the bottom plate 11. The openings 51 of the two opposite hard disk drive 50 between the two backplanes 15 are opposite each other, and the openings 51 of the hard disk drives 50 between the backplanes 15 and the side plates 17 are opposite the openings 171 of the side plates 17. The hard disk drives 50 are positioned to the bottom plate 11. The locking portions 411 of the fastening apparatus 40 are inserted between two hard disk drives 50 between the two backplanes 15, and inserted between the hard disk drive 50 and the side plates 17. The base plates 413 contact the top of the two hard disk drives 50 at the top of the hard disk drives 50 and the side plates 17. The two locking protrusion 4113 of each locking portion 411 are opposite to the openings 51 of the two hard disk drives 50, or are opposite to the opening 51 of the hard disk drives 50 and the opening 171 of the side plate 17. The hard disk drives 50 and the side plates 17 are resisted by the flexible arms 4151 of the connecting members 41. The resisting portions 433 of the fastening members 43 are opposite the mounting holes 4131 of the connecting members 41, and the guide strips 4337 of the fastening members 43 are opposite to the slide guide grooves 4138 of the connecting members 41. The pressing portions 431 are pressed until dents 4339 of the urging portions 4333 urge the raised portions 4137 of the connecting members 41. The sloping portions 4336 of the fastening members 43 urge the slide guide portions 4135 of the connecting members 41. The urging portions 4333 and the sloping portions 4336 urge the lower portions of two sides of the locking portions 411 to elastically deform toward the outside, and the locking knobs 4113 of the connecting posts 4111 are locked in the openings 51 of the hard disk drives 50 and the openings 171 of the side plates 17. The raised pillars 57 of the hard disk drives 50 and the raised pillars 173 of the side plates 17 are locked in the locking holes 4139 of the base plates 413. The hard disk drives 50, positioned between the backplanes 15 and between the backplanes 15 and the side plates 17, are resisted by the fastening apparatus 40.
When the hard disk drives 50 are to be detached from the housing 10, the fastening members 43 are pulled out from the mounting holes 4131. The dent 4339 of the urging portion 4333 moves along the raised portion 4137, and is detached from the raised portion 4137. The sloping portion 4336 is moved along the slide guide portion 4135. The locking portion 411 recovers from its elastic deformation, and the locking protrusion 4113 of the connecting post 4111 is detached from the opening 51 of the hard disk drive 50 or from the opening 171 of the side plate 17. The hard disk drives 50 can then be pulled away from the backplane 15.
The embodiments shown and described above are only examples. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the details, including matters of shape, size, and arrangement of the parts within the principles of the present disclosure, up to and including the full extent established by the broad general meaning of the terms used in the claims.
