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 FIGS. 1 and 2, an exemplary embodiment of an information handling system includes an information handling apparatus 200, a locking mechanism 300 connected to the apparatus 200, and a data storage device 100 received in the locking mechanism 300 and electrically coupled to the information handling apparatus 200 through the locking mechanism 300.
In one embodiment, the data storage device 100 is a universal serial bus disk. The apparatus 200 is a server, and 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 frame 31, a resilient retainer 33, and an adapter 35 secured in the frame 31.
The frame 31 includes a base 310, a cover 312, and a cap 314. The base 310 includes a bottom wall 3101, and two sidewalls 3103 perpendicularly extending up from opposite sides of the bottom wall 3101. A positioning pin 3102 extends up from the bottom wall 3101. Each of the sidewalls 3103 defines a notch 3104 adjacent to a front end of the base 310, and a recess 3105 in an inner surface of the sidewall 3103 and adjacent to a rear end of the base 310. In one embodiment, the cover 312 is made of transparent material, and includes a top wall 3121, and two flanges 3122 perpendicularly extending down from opposite sides of the top wall 3121. The top wall 3121 is stepped with a front portion of the top wall 3121 being lower than a rear portion of the top wall 3121. The cap 314 is a substantially rectangular box with an open front end, and two hooks 3141 extend forward from opposite ends of the front end of the cap 314.
The retainer 33 is a substantially U-shaped spring piece, and comprises two resilient arms 331 and a mounting portion 332 connected between bottoms of rear ends of the resilient arms 331. Each of the resilient arms 331 includes a manipulation 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, opposite to the mounting portion 332. The mounting portion 332 defines a positioning hole 3321.
The adapter 35 is secured in the front end of the base 310, and includes a first connector 351 extending forward out of the base 310, and a second connector 352 facing the rear end of the base 310. The first connector 351 is adapted to engage in the peripheral port 201 of the information handling apparatus 200. The second connector 352 is adapted to engage with the data storage device 100.
In assembly, the retainer 33 is mounted to the base 310, with the positioning pin 3102 of base 310 fixed in the positioning hole 3321 of the retainer 33. The resilient arms 331 of the retainer 33 respectively abut against inner surfaces of the sidewalls 3103 of the base 310, with the manipulation portions 3312 of the resilient arms 331 protruding out of the base 310 through the notches 3104 of the corresponding sidewalls 3103 of the base 310. The retaining tabs 3314 extend out of the frame 31 in front of the frame 31. The cover 312 is covered on a top of the base 310. The data storage device 100 is slid into the base 310 from the rear end of the base 310, to engage with and be electrically connected to the second connector 352 of the adapter 35. Since the cover 312 is transparent, it is convenient for checking whether the data storage device 100 is properly engaged with the adapter 35. The cap 314 is mounted to the rear end of the base 310, with the hooks 3141 correspondingly retained in the recesses 3105 of the sidewalls 3103 of the base 310. Therefore, the data storage device 100 is prevented from being accidentally drawn out of the base 310 and disconnected from the adapter 35.
Referring to FIG. 1 again, in use, the locking mechanism 300 is manipulated to allow the first connector 351 to be inserted into the peripheral port 201 of the apparatus 200 and electrically connected to the apparatus 200. Therefore, the data storage device 100 is electrically coupled to the apparatus 200 for data transmission through the adapter 35. At the same time, the retaining tabs 3314 of the resilient arms 331 of the retainer 33 are engaged in the corresponding retaining holes 203 of the apparatus 200 to secure the locking mechanism 300 to the apparatus 200. Therefore, the adapter 35 is prevented from being accidentally disconnected from the apparatus 200. Because the top wall 3121 of the cover 312 is stepped with the front portion of the top wall 3121 lower than the rear portion of the top wall 3121, a space is provided for manipulation of another port of the apparatus 200 above the peripheral port 201 of the apparatus 200.
To detach the data storage device 100 from the apparatus 200 with the base 310 remaining being mounted to the apparatus 200, the cap 314 is removed from the base 310 to expose the data storage device 100 from the rear end of the base 310. The data storage device 100 is drawn to the rear to be disconnected from the second connector 352 of the adapter 35, and thus can be removed out of the base 310.
To detach the data storage device 100 together with the locking mechanism 300 from apparatus 200, the manipulation portions 3312 of the retainer 31 are pressed towards each other to deform the resilient arms 331 and make the retaining tabs 3314 disengage from the retaining holes 203 of the apparatus 200. The locking mechanism 300 and the data storage device 100 received in the locking mechanism 300 then can be slid to the rear away from the apparatus 200 to disengage from 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.
