DETAILED DESCRIPTION
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 FIG. 1, an exemplary embodiment of an information handling system includes an information handling apparatus 200, a data storage device 100 inserted into the apparatus 200, and a locking mechanism 300 receiving the data storage device 100 and connected to the apparatus 200.
Referring to FIG. 2, in one embodiment, the data storage device 100 is a universal serial bus disk. The apparatus 200 defines a peripheral port 201, and two retaining holes 203 arranged at opposite sides of the peripheral port 201.
Referring to FIG. 3, the locking mechanism 300 includes a substantially rectangular frame 31 with a top and a front side of the frame 31 open, and a resilient retainer 33. The top side of the frame 31 provides access for mounting the retainer 33.
The frame 31 includes a bottom wall 311, two sidewalls 312 respectively perpendicularly extending up from opposite sides of the bottom wall 311, and a block 314 positioned at a rear end of the bottom wall 311 between the sidewalls 312. Each of the sidewalls 312 defines a notch 3121. Two positioning plates 316 extend up from the bottom wall 311, and are respectively near the sidewalls 312 to bound two locating slots 3126 between the positioning plates 316 and the corresponding sidewall 312. A mounting space 3146 is defined between rear ends of positioning plates 316 and the block 314.
The retainer 33 is a substantially U-shaped spring piece, and comprises two resilient arms 331 and a mounting portion 332 connected between rear ends of the resilient arms 331. Each of the resilient arms 331 includes a manipulating portion 3312 protruding out from the resilient arm 331, away from the other resilient arm 331. A retaining tab 3314 is formed at an outer surface of a front end of each of the resilient arms 331.
In assembly, the retainer 33 is mounted to the frame 31, with the mounting portion 332 of the retainer 33 positioned in the mounting space 3146 of the frame 31, and the resilient arms 331 of the retainer 33 respectively received the locating slots 3126 of the frame 31. The resilient arms 331 respectively resist against inner sides of the sidewalls 312 of the frame 31. The manipulating portions 3312 of the resilient arms 331 protrude out of the frame 31, through the notches 3121 of the corresponding sidewalls 312 of the frame 31. The resilient arms 331 of the retainer 33 extend forwards to make the retaining tabs 3314 in front of the frame 31.
Referring to FIG. 1 again, in use, the data storage device 100 is inserted into the peripheral port 201 of the apparatus 200 to be electrically coupled to the apparatus 200. The front end of the frame 31 is manipulated to align the frame 31 with a rear end of the data storage device 100, and then the frame 31 is inserted into the frame 21 between the positioning slots 316. At the same time, the retaining tabs 3314 of the resilient arms 331 of the retainer 33 are aligned with the corresponding retaining holes 203 of the apparatus 200. The frame 31 is further slid forward until the block 314 of the frame 31 abuts against the rear end of the data storage device 100, and thereby the retaining tabs 3314 are engaged in the corresponding retaining holes 203 of the apparatus 200 to secure the locking mechanism 300 to the apparatus 200. Therefore, the data storage device 100 is prevented from being accidentally disconnected from the apparatus 200.
To detach the data storage device 100 from the apparatus 200, the manipulating portions 3312 of the retainer 31 are pressed to deform the resilient arms 331 and make the retaining tabs 3314 disengage from the retaining holes 203 of the apparatus 200. Then the frame 31 can be slid rearwards away from the apparatus 200 to disengage from the data storage device 100. After disengagement of the frame 31 from the data storage device 100, the data storage 100 can be drawn out of the peripheral port 201 of the apparatus 200.
It is to be understood, however, that even though numerous characteristics and advantages of the embodiment have been set forth in the foregoing description, together with details of the structure and function of the embodiment, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the present disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
