1. Technical Field
The present disclosure relates to a fastening device for fastening a backplane in place.
2. Description of Related Art
A backplane is configured in a server. Hard disk drives are communicated with a motherboard through the backplane. The backplane is generally fastened to an enclosure of the server by screws. Accordingly, a screwdriver is needed in fastening the backplane in the enclosure. However, the operation of the screwdriver in the relatively small space of the enclosure is inconvenient.
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.”
The enclosure 10 includes a bottom plate 11, two side plates 12 extending up from opposite sides of the bottom plate 11, a top plate 13 connected between tops of the side plates 12, and a plurality of partition plates 15 connected between the top plate 13 and the bottom plate 11. A plurality of stop elements 16 is formed on the bottom plate 11, located in front of the partition plates 15. A flange 131 perpendicularly extends up from a front side of the top plate 13. Two stop tabs 132 extend backward from a top side of the flange 131. Four extension tabs 139 extend up from the top plate 13, near the flange 131. Two protrusions 133 extend up from the top plate 13. Each protrusion 133 axially defines a locking hole 1332. Two first bars 135 extend up from the top plate 13, located behind the protrusions 133 respectively. Each first bar 135 defines a positioning slot 1352 facing the corresponding protrusion 133. Two second bars 136 extend up from the top plate 13, near the protrusions 133 respectively. The second bars 136 are perpendicular to the corresponding first bars 135. Each second bar 136 defines a positioning slot 1362 facing the corresponding protrusion 133. Two arc-shaped limitation tabs 138 extend up from the top plate 13. The limitation tabs 138 surround the protrusions 133.
The pole 32 axially defines a pivoting hole 37 extending through the supporting foot 33. The pivoting hole 37 includes a first hoe 371 and a second hole 372 communicating with a bottom of the first hole 371. The diameter of the first hole 371 is greater than the diameter of the second hole 372. An arc-shaped mounting hole 38 is defined in the base body 31, surrounding the pole 32 and located at same sides of the operation portions 36.
To mount the backplane 2, three screws extend through three through holes 3 near an end of the backplane 2, and engage in the fastening holes 281 of one of the fastening members 20; three screws extend through the other three through holes 3, and engage in the fastening holes 281 of the other fastening member 20, to fasten the fastening members 20 to the top side of the backplane 2. The backplane 2 is supported on the bottom plate 11, and is sandwiched between the partition plates 15 and the stop elements 16. The bottom walls 25 of the fastening members 20 are supported on the top plate 13. The stop tabs 132 extend through the openings 26. The extension tabs 139 extend through the through holes 252. The pivoting members 30 are rotated, to allow the bumps 342 to engage in the positioning slots 1352 of the first bars 135. The second ends 35 of the pivoting members 30 block top surfaces of the bottom walls 25. The stop tabs 132 are located above the second ends 35 of the pivoting members 30, to block the second ends 35 of the pivoting members 30. Therefore, the backplane 2 is fastened to the enclosure 10.
The top plate 13 of the enclosure 10 includes two limitation tabs 138 to extend through the mounting holes 38 of the pivoting members 30. The limitation tabs 138 can limit the range of rotation of the pivoting members 30, to prevent the first ends 34 of the pivoting members 30 from rotating to the bottom walls 25, and prevent the second ends 35 of the pivoting members 30 from rotating toward the first bars 135.
After the fastening members 20 of the fastening device are fastened to the top side of the backplane 2, the backplane 2 is placed into the enclosure 10. The operator just rotates the pivoting members 30, the backplane 2 is then fastened in place, which is convenient.
Even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and the functions of the embodiments, the disclosure is illustrative only, and changes may be made in details, especially in the matters of shape, size, and arrangement of parts within the principles of the embodiments to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
