In the described data security protecting device of the utility model; When said first securing member of rotation makes said protection switch portable plate when moving away from the direction of said pcb board; Contact on said protection switch and the said pcb board breaks away from, and said pcb board sends the signal of the data message that removing preserved.
The beneficial effect that the data security protecting device of enforcement the utility model can bring is: when this related personnel illegally opens this protective device; Protection switch and pcb board break away from; Pcb board is removed canned data on it, thereby can protected data not be illegally accessed; This apparatus structure is ingenious, simple; The design mode of this device is hidden, and difficult quilt is discovered.
Description of drawings
To combine accompanying drawing and embodiment that the utility model data security protecting device is described further below, in the accompanying drawing:
Fig. 1 is the explosive view of the utility model data security protecting device;
The sectional view that Fig. 2 is the utility model data security protecting device when installation not;
Fig. 3 is the sectional view of the utility model data security protecting device after installation.
Embodiment
The structure and the principle of work of the data security protecting device of the utility model are described in conjunction with Fig. 1 to Fig. 3.
In this embodiment; This data security protecting device comprises first housing 1, second housing 2, pcb board 3 and protection switch portable plate 4; And first securing member 5 and second securing member 6; Wherein first housing 1 has containing cavity 101, is provided with 1 integrated with first housing, as to have first fixed orifice 1021 fixed leg 102 in this containing cavity 101; Have first through hole 201 on second housing 2; Pcb board 3 stores data message, and on have second through hole 301 and the 3rd through hole 302; Protection switch portable plate 4 is positioned in the containing cavity 101, which is provided with the protection switch 401 and second fixed orifice 402; This data security protecting device also comprises first securing member 5 and second securing member 6; Second securing member 6 passes the 3rd through hole 302 and is fixed in first fixed orifice 1021, said pcb board 3 is fixed on said first housing 1; First securing member 5 is fixed in second fixed orifice 402 after passing first through hole 201, second through hole 301 successively, and protection switch portable plate 4 is moved to the direction near said pcb board 3, and protection switch 401 is contacted with contact on the pcb board 3.Protection switch 401 can adopt the conduction carbon granules, be the young sheet of pot, thin film switch, microswitch etc.In further preferred embodiment, first through hole 201 is a countersunk.In further preferred embodiment, first securing member 5 and second securing member 6 are screw, and first fixed orifice 1021, second fixed orifice 402 are threaded hole with matching.
The principle of work of notebook data safety guard is: if want to obtain the data of storing in the pcb board; Then need take lower house apart, must unclamp first securing member 5, in case unclamp first securing member 5 and take lower house apart; Protection switch portable plate 4 is promptly to the direction motion away from pcb board 3; Thereby protection switch 401 breaks away from contact on the pcb board 3, and pcb board 3 sends the signal of the data message that removing preserved, thereby makes illegal invasion person can't obtain the data that will protect.
Need to prove that containing cavity 101 is the spaces between the pcb board and first housing, as long as its volume can ccontaining protection switch portable plate and left suitable space.When first housing did not have the sidewall of the setting and second shell, the sidewall of second housing can correspondingly increase height, so that first, second housing seal.For example, can be a surface plate that is provided with fixed leg with first case design, increase the sidewall of second housing, so that can sealing, first housing and second housing get final product.Equally, can be a surface plate also with first case design with groove, be provided with fixed leg in the groove, the size of second housing and this groove fit are so that first, second housing can seal just.In addition, the quantity of first securing member and second securing member also can be provided with according to concrete situation.
In fact,, before being fixedly connected, the protection switch portable plate is arranged in this containing cavity, again first housing and this protection switch portable plate is got final product through a screw retention as long as first housing is fixedly connected and leaves containing cavity with pcb board.Because pcb board passes for screw so should be provided with through hole on it between second housing and protection switch portable plate at this moment.So; Containing cavity one speech in the present specification might not be meant the holding part that the sidewall by first housing forms; And be meant that pcb board is fixedly connected the cavity that the back forms with first housing; In the embodiment shown in the figures, containing cavity forms after by fixed leg pcb board and first housing being separated a fixed gap.In fact, the technician can adopt other fixed forms of this area, as long as between above-mentioned two parts, leave certain gap.These embodiment do not exceed the ultimate principle and the design philosophy of the utility model, should be regarded as being equal to replacement.
Above embodiment is just in order to explain or describe the structure and the principle of the utility model, and its purpose is to let those skilled in the art can understand and implement this content, can not limit the protection domain of the utility model.Every equal variation and modification of in the utility model claim scope, being done all should belong to the covering scope of the utility model claim.
