       BACKGROUND 
       [0003]    A solid-state drive (SSD) is a data storage device that uses integrated circuit assemblies as memory to store data persistently. SSD technology uses electronic interfaces compatible with traditional block input/output (I/O) hard disk drives. SSDs do not employ any moving mechanical components, which distinguishes them from traditional magnetic disks such as hard disk drives (HDDs) or floppy disks, which are electromechanical devices containing spinning disks and movable read/write heads. Compared with electromechanical disks, SSDs are typically less susceptible to physical shock, are silent, and have lower access time and latency, however, the high manufacturing cost thereof prevents the widespread of the SSD. 
         [0004]    Usually, the SSD is mainly composed of three main components, such as housing, PCB having chips sealed thereon and the connecting port. Please refer to the U.S. Pat. No. 8,213,182 (hereinafter called as &#39;182), it discloses a housing case having an electronic circuit board, which includes: a lower case portion which internally houses a circuit board for mounting electronic components; and an upper case portion which is externally fitted to the lower case portion to form a box-like member. More specifically, the &#39;182 discloses a screw free SSD housing that can be easily assembled and disassembled. 
         [0005]    However, apart from the screw free SSD housing design, a need exists that some of the manufacturer may wants to prevent the consumer to disassemble the housing without the authorization thereof. Accordingly, a need of a low cost, simple design hosing capable of prevent the unauthorized disassembly of the consumer exists.

As shown in  FIG. 1A  and  FIG. 1B , the solid-state drive D (hereinafter called as SSD) of the present invention mainly includes a SSD housing  1  with a printed circuit board  2  (hereinafter called as PCB) secured therein. The PCB  2  may, but not limited to, be a circuit board having a plurality of NAND chips sealed thereon. Moreover, the SSD housing  1  is essentially composed of, but not limited to, a first member  10  and a second member  20 . 
         [0022]    As shown in the  FIG. 1A  and  FIG. 1B , the first member  10  is, but not limited to, the lower casing of the SSD housing  1  and has a plurality of first hollows  13  formed thereon. The second member  20  is, but not limited to, the upper cover of the SSD housing and has a plurality of fastening structures  22 . By simply pressing the edge material of the second member  20 , the edge material thereof shall be plastically deformed into the first hollows  13  of the first member  10  so as to secure the first member  10  with the second member  20  with no screw liked fasteners required. It should be noticed that, the edge material of the second member  20  may be optionally dug into the surface of the first member  10  for better fixity. 
         [0023]    The details of the assembling process of the SSD housing  1  shall be herein described. First, a first member  10  and a second member  20  have to be prepared. Please refer to  FIG. 2A  and  FIG. 2B ,  FIG. 2A  and  FIG. 2B  are schematic drawings illustrating the first member of the embodiment of  FIG. 1A  in various viewing angles. By the  FIG. 2A  and  FIG. 2B , it is clearly shown that the first member  10  has a first base  11  and a sidewall  12 . The first base  11  has a first inner base surface  11 B and a corresponding first outer base surface  11 A with a plurality of first hollows  13  formed thereon. In this embodiment, the first hollows  13  may, or may not, extends along the edge of the first base  11  and be groove shaped. Moreover, the first hollows  13  are not penetrated through the second member  20  so as to maintain the tightness thereof. Furthermore, the width WD of the first hollows  13  are larger than the depth DP thereof so as to allow the end of the end portion  222  of the fastening structure  22  to be pressed and plastically deformed therein. 
         [0024]    The sidewall  12  has an outer sidewall surface  12 A and a corresponding inner sidewall surface  12 B, the sidewall  12  extends outward vertically from the first inner base surface  11 B and forms along the circumference of the first base  11  so as to surround and define a spacing S therein, allowing the PCB  3  or other essential electronic member to be disposed therein. Furthermore, apart from the first hollows  13 , the first member may, or may not, further has a second hollows  16  formed on the outer sidewall surface  12 A as shown in the figures. 
         [0025]    Furthermore, the first member  10  may further has a platform  15  formed on the inner sidewall surface  12 B, horizontally extended inwardly from the inner sidewall surface  12 B, for supporting the PCB  2  thereon. It should be noticed that the sum of the height of the platform  15  and the thickness of the PCB  2  is preferred to smaller than the total height of the sidewall  12  in order to spare a reasonable size of space for the PCB  2 . Moreover, the sidewall  12  may further has a plurality of tenon  14  formed on the inner sidewall surface  12 B. The tenons  14  horizontally extend inwardly from the inner sidewall surface  12 B and have approximately the same height as the sidewall  12 . The plurality of tenons  14  may be utilized to position the PCB  2  by the mortises of the PCB  2 . Furthermore, in order to secure the PCB  2  with the first member  10 , a plurality of thin layers of dielectric adhesive material (grey colored) may be disposed among the interface of the first member  10  and the PCB  2 . In the present embodiment, the first member  10  may, but not limited to, be formed of a metal or polymer material by die casting process and the first base thereof may only has an average thickness of 0.035 inches. More specifically, the first member depicts in the  FIG. 2A  and  FIG. 2B  has the length, width and the height of approximately 2.75 inches, 3.95 inches and 0.22 inches. 
         [0026]    Please refer to  FIG. 3A  and  FIG. 3B ,  FIG. 3A  and  FIG. 3B  are schematic drawings illustrating the second member of the embodiment of  FIG. 1A  in various viewing angles. By the  FIG. 3A  and  FIG. 3B , it is clearly shown that the second member  20  has a second base  21  and a plurality of fastening structures  22  extended therefrom. The second base  21  has a second outer base surface  21 A and a corresponding second inner base surface  21 B. Each of the plurality of fastening structures  22  has a corresponding inner surface  22 A and outer surface  22 B respectively. The plurality of fastening structures  22  extend outward vertically from the second inner base surface  21 B which the fastening structure  22  may, but not limited to, be one piece formed with the second base  21 . More specifically, a flat state second member  20  may firstly be formed by blanking process from a plate shaped material. Then, the fastening structures  22  may be folded so as to form the second base  21  and fastening structure  22  as depicted in  FIG. 3A . More specifically, the second member  20  is preferred to be formed of a metal or polymer material. 
         [0027]    Moreover, in actual practice, the entire, or at least part of the, internal surface of the second member  20  may optionally has an adhesive AD applied thereon for subsequent use. More specifically, in the embodiment, the entire internal surface of the second member  20 , including the inner surface  22 A of the fastening structures  22  and the second inner base surface  21 B, may has an adhesive AD applied thereon before the initial folding process. 
         [0028]    More specifically, in the embodiment, each of the fastening structure  22  may comprises a body portion  221  and end portion  222 , the end portion  222  is formed on the top end of the fastening structures  22  and be connected to the second inner base surface  21 B via the body portion  221 . Before the assembly, the extending direction of the body portion  221  is approximately the same as the extending direction of the top end of the end portion  222 . However, after the assembly, the extending direction of the body portion  221  may either vertical or inverse to the extending direction of the top end of the end portion  222  so as to secure the first member  10  with the second member  20 . Moreover, at least one interval  23  is formed between the plurality of fastening structures  22  so as to allow the internal contents to be exposed therethrough. In the present embodiment depicted in the  FIG. 3A  and  FIG. 3B , the second base of the second member  20  may only has an average thickness of 0.01 inches and the length and the width is approximately 2.75 inches and 4 inches. 
         [0029]    Please refer to  FIG. 4A ,  FIG. 4B  and  FIG. 4C ,  FIG. 4A ,  FIG. 4B  and  FIG. 4C  depicts the assembling process of the present invention. The  FIG. 4A to 4C  are corresponding to the cross-section diagrams along the Z-Z of  FIG. 1 . Once the first member  10 , the second member  20  and the PCB  2  are ready, then the assembler may begin the assembling process by disposing the PCB  2  onto the platform  15  and matching the tenon  14  of the PCB with the mortise  31  of the PCB. Then, the assembler may connects the sidewall  12  of the first member  10  with the second inner base surface  21 B so as to cover the spacing S thereby. Meanwhile, the body portion  221  of the fastening structures  22  covers part of the outer sidewall surface  12 A, and at least part of the end portion  222  excess the first outer base surface  11 A. 
         [0030]    Then, the user may utilizes pressing tool, such as arbor press, or any other mechanical means to plastically deform the top end of the end portion  222  and force the top end thereof to be disposed into the corresponding first hollow  13  as shown in the  FIG. 4B . It should be noticed that the top end of the end portion  222  is preferred, but not essentially, to be stamped, dug or embedded into the surface of the first hollow  13  by mechanically deforming the surface of the first hollow  13  with huge amount of force applied via the fastening structure  22 . More specifically, the top end of the fastening structures are dug into the surface of the corresponding first hollows with approximately no interval formed between the embedded portion of fastening structures and the surface of the first hollow  13 . Furthermore, the said crimpling process may be done by repeatedly applying various forces from various angles thereto so to as to create teeth like effect from the second member  20  to create grips so as to fix the first member  10  with the second member  20 . Therefore, the amount of deformation of each of the surface of the first hollow  13  and the top end of the end portion  222  is approximately the same. 
         [0031]    After the pressing process, the end portion  222  of the fastening structure  22  buckles with the first base  11  so as to secure the first member  10  with the second member  20  mutually. In the embodiment, the fastening structure  22  is now an U shaped hook liked structure. More specifically, while the first member  10  and the second member  20  are mutually secured, the extending direction of the body portion  221  may approximately inverse to the extending direction of the top end of the end portion  222 . However, the shape thereof is not limited to a U shaped hook, the end portions  222  of the fastening structures  22  may also be V shaped, L shaped, C shaped or any other shape that are capable of fixing the relatively positions of the first member  10  and the second member  20 . 
         [0032]    Then, the assembler may, but not essentially, crimping the body portion  221  of the fastening structure  22  and plastically deforming the body portion  221  into the second hollows  16  by roll crimp process so as to provide more fixing capability. Meanwhile, the first member  10  or second member  20  may be heated so as to activate the dielectric adhesive material to provide further stability. Meanwhile, please refer to the  FIG. 5 ,  FIG. 5  illustrates the schematic figure of the second member after the said second crimping process. 
         [0033]    As described above, the SSD housing can easily be assembled by simply pressing and plastically deforming the fastening structure of the second member  20  into the first hollow  13  so as to fix the relative position therebetween. By the said process, the screw liked fasteners and the screwing process thereof can be omitted and the unauthorized disassembly of the consumer can also be prevented since the disassembly thereof shall lead to the destruction of the housing  1 . However, in the product maintaining process or malfunction eliminating process, the disassembly of the SSD housing can still be completed by pulling the end portion  222  of the fastening structure  22  toward the V cut portion  17  (or called as groove liked structure), the groove liked structure  17  extending along the outer sidewall surface as depicted as the enlarged figure shown in the  FIG. 2B . Meanwhile, the second member is destroyed but PCB is safe. Accordingly, only the manufacturer itself may process the disassembly process since the consumer has no relative machine or raw member to replace the broken member previously described. 
         [0034]    Compared to the prior art, the solid-state drive housing, the solid-state disk using the same and the assembling process thereof in the present invention is provided with fewer components and easy assembly, so as to reduce the assembly cost of the solid-state drive significantly. Furthermore, the present invention may also capable of preventing the unauthorized disassembly of the consumer.
