Description
Technical field
The utility model relates to a kind of electromagnetic armouring structure, particularly extracts the electromagnetic armouring structure of box about a kind of hard disc of computer that is applicable to, it is electromagnetic radiation shielding effectively.
Background technology
For computing machine, under the interference effect of electromagnetic radiation, can cause information transmission mistake, harm such as the abnormality of botching routines, work.In addition, computing machine itself also can produce certain harm to other electronic equipment and human body as interference source.Therefore, it is necessary floppy drive or hard disk being carried out electromagnetic screen.In the past, adopted isolation method more or,, had drawbacks such as complex structure, installation inconvenience though so make effect obvious with the can sealing.
In view of this, industry has begun to adopt the electromagnetic screen sheet to come electromagnetic radiation shielding.The continent patent has disclosed a kind of electromagnetic screen that is used for floppy drive or hard disk for ZL93232185.2 number.This device comprises the U-shaped framework that the thin cold-rolled steel sheet of a usefulness is made, and a usefulness screw is installed on the framework and height adjustable shifting board.This frame size is identical with the physical dimension of floppy drive or hard disk.During use, whole device is installed in the appropriate location of placing floppy drive or hard disk in the computing machine, to reach the effect of electromagnetic screen.
Yet above-mentioned electromagnetic screen has adopted two-part construction, and one-piece construction is still complicated, install also more loaded down with trivial details, thereby improved production and assembly cost greatly.Its U-shaped framework and shifting board are planar structure, therefore with the adjacent metal plate body to contact effect also relatively poor, thereby reduced actual effectiveness.
In addition, existing a lot of electromagnetic screen sheets all only provide up and down or the electromagnetic screen of left and right directions usually, thereby also have not exclusively this weak point of electromagnetic screen.Disclosed a kind of electromagnetic screen of being located at the Computer optical disc drive mouth for ZL01266070.1 number as the continent patent, it is a flap of being located at the inboard CD-ROM drive of CD-ROM drive mouth top, and this flap is provided with several shell fragments and is used for contacting with the CD-ROM drive shell.From its structure as seen, this electromagnetic screen only can provide the electromagnetic screen of top.
Therefore,, be necessary to provide a kind of hard disk electromagnetic armouring structure of innovation for overcoming the defective that above-mentioned prior art exists, its simple in structure, simple installation, and can provide effectively, effectiveness completely.
Summary of the invention
One of the purpose of this utility model is to provide a kind of simple in structure, easy-to-install hard disk electromagnetic armouring structure.
Another purpose of the present utility model is to provide a kind of to be provided effectively, the hard disk electromagnetic armouring structure of effectiveness completely.
For achieving the above object, hard disk electromagnetic armouring structure of the present utility model comprises a main part, and lower edge and extended in the opposite direction first and second elastic contact part of both side edges from the main part respectively.Main part is provided with several perforation, accommodates between the framework so that this main part can be assembled the panel and the hard disk that insert and put to a hard disk abstraction box.First elastic contact part comprises that several are spaced, the elastic arm of integrated punching moulding, and a junction that connects each elastic arm end.Second elastic contact part comprises an approximate clamping part that takes the shape of the letter U, and extends from clamping part, is used for two elastic arms that hold mutually with the corresponding set groove in the panel side of hard disk abstraction box.This clamping part is used for and the set projection of the panel trailing flank ora terminalis of hard disk abstraction box buckle mutually.The elastic arm of first and second elastic contact part is arc structure, which is provided with the contact with inconsistent with the adjacent metal plate body, thereby realizes electro-magnetic screen function.
Compared with prior art, the utility model hard disk electromagnetic armouring structure is the single piece type structure, simple structure, simple installation.Simultaneously, this electromagnetic armouring structure can effectively shield the place ahead, about and the up and down electromagnetic radiation of all directions.
Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Embodiment
Relevant detailed description of the present utility model and technology contents, existing as follows with regard to accompanying drawings:
As shown in Figure 1, the utility model is a kind of electromagnetic armouring structure, refers in particular to a kind of electromagnetic armouring structure that is applicable to the hard disk abstraction box.The hard disk that this hard disk electromagnetic armouring structure 1 is assembled in the hard disk abstraction box is accommodated between framework 2 and the panel 3.
As shown in Figure 2, this hard disk electromagnetic armouring structure 1 comprises a main part 10, extended several first elastic contact parts 11 of lower edge from the main part 10, and from extended two second elastic contact parts 12 of main part 10 lateral margins.
Please consult Fig. 1 and Fig. 2 simultaneously, each direction towards framework 2 of the last lower edge of main part 10 tilts to extend several spaced first elastic contact parts 11.Each elastic contact part 11 comprises that several are spaced, the elastic arm of integrated punching moulding 110, and the end of these elastic arms 110 is connected by a junction 111.As Fig. 3 and shown in Figure 5, each elastic arm 110 is an arcuate structure, protrudes out one suitably highly, so that its end face contact 1100 can be inconsistent with the adjacent metal plate body, thus the function of realization shielding above-below direction electromagnetic radiation.
The lateral margin of main part 10 is towards extending two second elastic contact parts 12 away from the direction of framework 2.This second elastic contact part 12 comprises an approximate clamping part 120 that takes the shape of the letter U, and by clamping part 120 towards the tilt elastic arm 121 of extended two integrated punching moulding of the direction away from framework 2.As shown in Figure 3 and Figure 4, the set projection 32 of clamping part 120 and panel 3 rear end face lateral margins is interlocked, and elastic arm 121 is then accommodated forward and is limited in the corresponding set groove 31 in panel 3 sides.Each elastic arm 121 is an arcuate structure, protrudes out a suitable distance to side, so that its end face contact 1210 can contact with the adjacent metal plate body, thus the function of realization shielding left and right directions electromagnetic radiation.
In sum, the utility model hard disk electromagnetic armouring structure 1 is the single piece type structure, constructs very simple.During installation, only need its main part 10 is folded between framework 2 and the panel 3, make second elastic contact part 12 of its both sides be fastened in respective slot 31 interior the getting final product of panel 3, therefore, install also very easy.What is more important, this its main part 10 of electromagnetic armouring structure 1 mat and first, second elastic contact part 11,12 can effectively shield the place ahead, about and the up and down electromagnetic radiation of all directions, thereby make effectiveness more effective, complete.
