New description: [New technical field] This creation involves an anti-electromagnetic interference housing, especially a kind of anti-electromagnetic interference housing with convenient installation and simple structure. [Prior Art] It is well known that electronic components generate electromagnetic waves during operation, and electromagnetic waves radiate outward if they are unrestricted, which may interfere with the reception of other electronic devices that transmit signals by electromagnetic waves, and may also cause damage to other electronic products. The performance of the computer is reduced by the influence of many electronic components. The operation of the computer is caused by electromagnetic radiation, and with the gradual popularization of electronic devices such as computers, the speed of operation and the increase of frequency, the electromagnetic interference problem is also increasing. serious. Therefore, countries generally have strict regulations on the electromagnetic waves that can be generated by computers. For example, the Federal Communication Commission has established mandatory electromagnetic compatibility standards. In the design of electronic devices such as computers, in order to achieve the above-mentioned electromagnetic compatibility standards, the housing of the conductive material must be electromagnetically shielded, and the housing of most electronic devices is different in relative movements such as: The upper cover, the base, the side plates, and the like are combined, so that there is a gap in the joints of the respective parts, which causes electromagnetic waves to be excited, thereby causing extremely serious obstacles in conformity with the electric-accumulation standard. Studies have shown that if the electromagnetic compatibility standard is to be achieved at the joints of the various parts such as the money seat, the gap should not exceed one-twentieth of the wavelength of the signal, and the spacing of the joints of the computer housings today is much larger than this value. In order to solve this problem, various methods have appeared in the industry. Among them, the upper cover and the frame are indirectly sewn by screws. Although it is reliable, it is neither practical nor economical, and the most commonly used method of M285201 In the upper cover and the machine seat, set a number of conductive material shrapnel, do not with the cover and machine to lose _, such as __ sunny anti- (four) shot dry (four) piece, firmly on the first and second side of the box, each-bomb (4) Set the through hole of the interval interval 1 1 The longitudinal coffee is provided with a protruding piece which is perpendicular to the edge of the through hole and protrudes outwardly with respect to the side of the receiving box, and the magnetic interference interference shrapnel needs to be riveted. The combination or screw method and the housing _, and the protruding material is suitable for the force installation in four directions, and the function is greatly limited. [New content] In view of the above, it is necessary to provide an electromagnetic interference-proof housing that is simple in structure, flexible, and easy to handle. The anti-hair magnetic interference device comprises a spring piece, a connecting plate used together with the upper cover and the upper cover. The elastic piece is provided with a plurality of tongues. The connecting plate has a plurality of openings, and the tongue pieces pass through the openings The upper cover is in conflict. Compared with the prior art, the anti-electromagnetic interference housing has a simple structure, and can directly buckle the female scorpion without the screw, and the elastic piece is provided with a hemispherical protrusion, which can be conveniently installed in multiple directions, thereby effectively preventing electromagnetic light radiation interference. [Embodiment] Referring to the first embodiment, the electromagnetic interference prevention housing of the preferred embodiment of the present invention includes a resilient piece 10, a connecting plate 30 for clamping the elastic piece 10, and a matching upper cover 50 for forming Enclosed structure to achieve anti-electromagnetic interference. Referring to the second to fourth figures, the elastic piece 10 is spaced apart from one side to form a plurality of elastic positioning pieces 12, and one side of each positioning piece 12 defines a U-shaped snap hole 18, which is 4 M285201 5 The early piece 10 extends from the end of the snap hole 18 - an elastic tongue ί 4 , and the free end of the tongue piece is provided with a hemispherical protrusion 16 in the same direction as the positioning piece 12 . Referring to FIG. 5 , a side of the connecting plate 30 is bent and has a folded edge. The folded edge includes an outer surface 33 and an inner surface 35 , and the folded edge 3 i defines a plurality of positions that can be engaged with the positioning piece U of the elastic piece. The hole 32, the fold _ corresponding to the protrusion π of the elastic piece (7), opens a plurality of circular openings 36, and the folded edge 31 corresponds to the snap hole of the elastic piece (10), and has two L-shaped card fishing 38 for use with the elastic piece 1 The snap button hole 18 is fitted. Please refer to the sixth figure to the eighth figure together. When assembling, firstly, the card fishing card 38 of the connecting plate passes through the snap hole 18' of the bullet, and then the elastic piece 1() is made to the connecting plate (10), the riding end. (not shown) the square (10) moves, so that the end of the snap hole 18 abuts against the catch 38 of the connecting plate 30. The folded end (not labeled) the retaining piece 12 is locked by the connecting plate, when the positioning piece is When sliding to the positioning hole 32, the shape of the positioning piece (1) before the gray elastic deformation is just engaged in the corresponding positioning hole 32; the protrusion % is affected by the connecting plate 3, and the tongue piece is correspondingly generated. The elastic deformation is performed when the positioning piece 12 is fastened in the corresponding positioning hole 32. The protrusion 16 is just engaged with the connecting plate such as the opening hole. After snapping, the hemispherical top of the projection 16 passes through the opening % and protrudes from the outer surface 33 of the flange 。. The tongue piece 14 assembled to the connecting plate of the plurality of elastic pieces (7) is elastically deformed by using the upper cover 100%, so that the protrusion 16 of the elastic piece (1) tightly abuts against the upper cover 5〇, since Zhongyi卩, 灭—closed ^ electrical loop to achieve electromagnetic shielding.
