Description

Device with anti-dismantling structure

[ technical field ] A method for producing a semiconductor device

The present invention relates to a device with an anti-disassembling structure, and more particularly, to a device with an anti-disassembling structure without the need of screw locking.

[ background of the invention ]

For specific electronic products, such as Solid State Disk (SSD), Intelligent Battery Backup Unit (iBBU), or other electronic products, manufacturers want users not to disassemble the housing during use or during warranty, because the user can damage internal related parts due to human factors after disassembling the housing by himself, and the vendor can not identify the cause of real damage by after-sale service; or if the internal relevant parts (such as heavy metal inside the battery) are not contacted by professional tools, the injury and safety threat to the body of the user can be caused.

The existing anti-detachment design generally includes two designs, one is to attach an anti-detachment Label (No removable Label), and the other is to use special screws. The first design is to cover the screw hole with a tamper-evident label made of a fragile paper material after the screw is fastened, thereby preventing the user from detaching. The second approach is primarily to increase the difficulty of disassembly, since special tools must be used to perform the disassembly. If the user detaches the screw privately, the anti-detaching label or the special screw and the connecting part thereof are damaged. Therefore, when the electronic product is returned to the factory for maintenance, the salesperson can judge whether the electronic product is disassembled by the user according to the integrity of the anti-disassembly label or the special screw.

However, since the anti-detachment label is simply adhered to the electronic product housing and the special screw cannot completely prevent the user from detaching without damage, a design of anti-detachment is proposed to prevent the user from detaching fundamentally, so that the front-end salesperson can clearly know whether the electronic product has been detached and clearly determine the responsibility between the manufacturer and the user, thereby avoiding unnecessary loss of the manufacturer.

Therefore, fastener 200 of the present invention has the advantages of easy formation, simple structure and low cost.

Please refer to fig. 4, fig. 5 and fig. 6. FIG. 4 is a cross-sectional view of the anti-tamper device 100 with hook portions 230 of fasteners 200 mounted to one of the shells; FIG. 5 is a cross-sectional view of the anti-tamper device 100 of the present invention, wherein two ends of the fastener 200 are fastened to the first bump 130 and the second bump 170; and FIG. 6 is a cross-sectional view of the device 100 with a tamper-evident structure of the present invention applied to a storage device. The first housing 110 has a first opening 120 formed on an outer surface thereof. The first housing 110 has a first protrusion 130 integrally formed thereon, and the first protrusion 130 protrudes from an inner wall of the first opening 120. The outer surface of the second housing 150 is provided with a second opening 160. The second housing 150 has a second protrusion 170 integrally formed thereon, and the second protrusion 170 protrudes from the inner wall of the second opening 160.

The first housing 110 further includes a first hole 140, and the second housing 150 includes a second hole 180, wherein one end of the first hole 140 and one end of the second hole 180 are connected to each other. In addition, the other end of the first hole 140 is communicated with the first opening 120, so that the extending direction of the first hole 140 is perpendicular to the extending direction of the first opening 120; similarly, the other end of the second hole 180 is connected to the second opening 160, such that the extending direction of the second hole 180 is perpendicular to the extending direction of the second opening 160, and the holes 140, 180 and the openings 120, 160 are connected to each other to form a horseshoe-shaped through hole (not shown).

When the first housing 110 and the second housing 150 are mutually covered, the first bump 130 and the second bump 170 are correspondingly attached to each other. The two bending portions 220 of the fastener 200 can respectively penetrate through the first opening 120 and the second opening 160, and the two hook portions 230 respectively further fasten the first bump 130 and the second bump 170. Referring to fig. 4, one hook 230 of the fastener 200 can be pushed by an external force (see the dashed arrow) to slide the hook 230 into the second opening 160 along one side of the second bump 170, so as to be fastened to the other side of the second bump 170. After one end of the fastener 200 is fastened to the second protrusion 170 of the second housing 150, an external force is applied to fasten the hook 230 at the other end to the first protrusion 130 of the first housing 110, so as to complete the operation of the anti-detachment structure of the present invention, as shown in fig. 5.

each hook 230 is fastened to the other side of the first bump 130 and the other side of the second bump 170, preferably to the wall of the first bump 130 protruding from the first hole 140 and the wall of the second bump 170 protruding from the second hole 180. In addition, according to different installation manners, the user can also directly fasten the two hook portions 230 of the fastener 200 to the first bump 130 and the second bump 170. That is, when the fastener 200 is applied with an external force, the two hook portions 230 slide into the second opening 160 and the first opening 120 along one side of the second protrusion 170 and one side of the first protrusion 130, respectively, so as to fasten the other sides of the second protrusion 170 and the first protrusion 130.

As shown in FIG. 5, the lengths of the first opening 120 and the second opening 160 are both greater than or equal to the length of the two bending portions 220, so that the fastener 200 of the present invention is completely accommodated in the first opening 120 and the second opening 160. In addition, the connecting portion 210 further has an arc surface 212 bending toward each hook 230, when each hook 230 of the fastener 200 is fastened to the first bump 130 and the second bump 170, the arc surface 212 can be attached to the outer surfaces of the first bump 130 and the second bump 170, thereby reducing the possibility of being pulled out or removed by a tool (not shown).

Referring to fig. 6, when the present invention is substantially applied to the storage device 100, such as an SSD hard disk, a flash memory device 190 is disposed between the first casing 110 and the second casing 150. In order to prevent the storage device 100 from being disassembled during the guarantee period or the appreciation period, at least 4 assembly holes (formed by the first opening 120 and the second opening 160) are provided, and 4 fasteners 200 need to be fastened relatively, wherein the number is not limited.

FIG. 7 is a first cross-sectional view of fastener 200 of the present invention detached from first housing 110 and second housing 150, and FIG. 8 is a second cross-sectional view of fastener 200 of the present invention detached from first housing 110 and second housing 150. When the fastener 200 is detached from the first bump 130 and/or the second bump 170 of the first casing 110 and/or the second casing 150 due to external force, the wall surfaces of the hook portions 230 that engage with the first bump 130 and the second bump 170 will deform gradually. Since the length of each bending portion 220 is greater than the length of each hook portion 230, when the fastener 200 is completely separated from the first opening 120 and the second opening 160, each hook portion 230 will deform until being broken or broken.

When the user returns the device 100 to the salesperson or after-sales service staff, the front salesperson or after-sales service staff can easily and clearly identify/judge by breaking or breaking the hook 230, and the device 100 is detached to immediately clear the responsibility assignment problem between the manufacturer and the user, thereby avoiding the loss of the manufacturer.

In view of the foregoing, it is intended that the embodiments disclosed herein be considered as illustrative rather than limiting.
