Abstract
The utility model provides a static protective device, which mainly comprises a printed circuit board, a protecting hood that contains the printed circuit board, and a metal spring plate; wherein, the spring plate is bent into a bending part, a cocking part, and a flat and straight part with two ends being connected with the bending part and the cocking part; the flat and straight part is fixed on the inner side of the protecting hood; the tail end of the cocking part rolls up upward and is contacted with the printed circuit board; moreover, the bending part is contacted with a conductive screw drilling through the hood. The static protective device not only has simple structure, but also conducts the static on the conductive screw to a connector on the printed circuit board through the spring plate to conduct out the static, thus achieving the purpose of static protection.
Description
Technical field
The utility model relates to a kind of protector, relates in particular to a kind of device that is used for electrostatic defending.
Background technology
Up-to-date wireless terminal product great majority have all been equipped high speed interface.Except that increasing interface to increase the new function, the challenge that reduces product size does not still change, and product is also developing to small and exquisite, frivolous direction.
Numerous interfaces converge in the small space; the residual static of meeting when moment of pulling out connector or powered-down; and static may cause the damage of hard disk internal circuit and losing of storage data; static discharge (being ESD) disturbs the circuit that damages on the printed circuit board (PCB); in addition; because the increase of function; the IC design is responsive more to ESD; the designer is when selecting suitable protection assembly for circuit; can make IC that the most effective esd protection is provided as far as possible, allow the protection assembly not take too many machine board space and cost simultaneously.
The general conducting foam that uses of traditional protection design, described conducting foam is to make at the conductive fabric that the outsourcing of sponge core has conductivity to form, but because the conducting foam poor heat resistance, can cause coming unstuck, thereby drop and lose the function of preventing electro-static discharge because of overheated or other factors.
Summary of the invention
In view of the above problems, the utility model provides a kind of electrostatic protection apparatus, and this device utilizes an elastic piece structure simple in structure to carry out electrostatic guide, does not take the machine board space, and this elastic piece structure fixes by thermosol, is not easy to drop.
For reaching the problems referred to above, the utility model has adopted following technical scheme: a kind of electrostatic protection apparatus, it mainly comprises a protective cover, one is placed in the printed circuit board (PCB) and a shell fragment of this protective cover inside, wherein, described shell fragment is bent into a kink, one warping part and two ends respectively with this kink, the flat part that the warping part links to each other, and this flat part is fixed in above-mentioned protective cover inboard, this warping part contacts with above-mentioned printed circuit board (PCB), again, one conduction screw passes protective cover and contacts with the shell fragment kink, so, the static on this conduction screw conducts on the printed circuit board (PCB) through shell fragment.
Preferable, the utility model also provides a kind of electrostatic protection apparatus, and wherein, described shell fragment is one to have the sheet metal of conductivity; The warping part end of described shell fragment scrolls up, and increases the area that contacts with printed circuit board (PCB), this printed circuit board (PCB) of unlikely damage; The flat part of described shell fragment is provided with a slotted eye, is fastened fixing with a projection that is provided with protective cover.
Compared to prior art, the utility model provides a kind of electrostatic protection apparatus, will conduct electricity static on the screw by shell fragment and conduct to connector on the printed circuit board (PCB), so that static is spread out of, reaches the purpose of electrostatic defending.

Embodiment
Please refer to Fig. 1 to shown in Figure 3, the utility model comprises that mainly a protective cover 10, is placed in printed circuit board (PCB) 20, a shell fragment 30 and the conduction screw 40 in the above-mentioned protective cover 10.In present embodiment, this protective cover 10 is an example with a MB shielding.
Wherein, described protective cover 10 comprises a loam cake 101 and a lower cover 102, these 1013 two ends, loam cake 101 1 sides carry over its side 1013 directions respectively and extend an extension 1011, and also be provided with a through hole 1012 on this extension 1011, again, these lower cover 102 1 sides 1021 are provided with a perforation 1022.
In addition, described printed circuit board (PCB) 20 is placed in described loam cake 101 and lower cover 102 correspondences cover in the protective cover 10 of back formation, and this printed circuit board (PCB) 20 a wherein side is provided with some resistance, some connectors 202 and a SATA hard disk 203.
Moreover, please refer to shown in Figure 1ly, be the schematic diagram of described shell fragment 30.Described shell fragment 30 is formed by the sheet metal bending of a strip, and this shell fragment 30 has certain conductivity, and it mainly comprises the flat part 302 that a kink 301, one warping parts 303 and two ends link to each other with this kink 301 and warping part 303 respectively.
Warping part 303 outside perks and its end of described shell fragment 30 scroll up slightly, when being beneficial in shell fragment 30 is fixed in protective cover 10, increase the contact area of this shell fragment 30 and printed circuit board (PCB) 20, and be not easy to damage printed circuit board (PCB) 20, reach the purpose of effective conduction static, in present embodiment, the flat part 302 of this shell fragment 30 is provided with a slotted eye 3021, for the 1014 corresponding blockings of the projection on the loam cake 101 of protective cover 10, and further be fixed on this protective cover 10 by the flat part 302 of the fixing mode of thermosol with this shell fragment 30, after this loam cake 101 and these lower cover 102 corresponding covering, the warping part 303 direct contact print circuit boards 20 of shell fragment 30, again, this conduction screw 40 passes the perforation 1022 of described lower cover 102 in turn, the through hole 1012 of described loam cake 101, last kink 301 with described shell fragment 30 is in contact with one another, conduct to connector 202 on the printed circuit board (PCB) 20 with the static that will conduct electricity on the screw 40 through shell fragment 30, thereby static is spread out of, reach the purpose of electrostatic defending.
