Description of the invention (1) The present invention provides a computer case, particularly a computer case that can be used to reduce electromagnetic radiation. Generally, a computer is composed of many modules such as interface cards, hard disks, and power supplies. These modules are housed in a computer case and communicate with each other through many different electrical connections. These modules and Electrically connected, electronic Λ numbers all report a high frequency 'for example, the frequency of the central processing unit is as high as several hundred ㈣2', so it will generate a lot of electromagnetic radiation (electromagnetic = Ve). Electromagnetic radiation will adversely affect the user or the surrounding environment. Electromagnetic interference (e 1 ectromagnet ic wave i nter f erence ^ ...) Snow ^ ί Each country or region has established a standard of electromagnetic interference $, and Hungary Israel has also invested a lot of research to reduce the electromagnetic radiation of computers. Reduce the area of the computer and use the electrical port that shields the touch to create several areas. The external area of the area is reduced, and the computer case is used to block the integrated effect of the brain. The surrounding area of the brain forms an electromagnetic field. Break the electromagnetic radiation to break the shape of the electromagnetic radiation, such as one. However, the floppy disk device needs to be installed outside the radiation line, and the radiation from each area is leaked to it. However, there are ways to radiate the computer's electromagnetic radiation. Another is the general computer's machine or optical disc. The computer case. Besides the other areas of the computer, the internal gold leaks. Many kinds of electromagnetic radiation are needed inside the opening of the brain shell metal external machine, etc. It also belongs to the board. Among them, the computer is guided by the shell, used by the place of use, and radiated by the metal. Each electric object is made of electric crane, which is directly connected to the open plate on the shell and separated into a quantity so that a break of electromagnetic radiation will not form.

Description of the invention (2) It is known to deal with the gap between the metal plate and the case inside the computer by using some elastically deformable conductive elements, such as conductive sponges or metal springs, and placing the plug on the metal plate. The gap between the shell and the case, due to the electrical conductivity of the element, the element will form a kind of electromagnetic radiation shielding (RIL) to interrupt the electromagnetic radiation leakage through this gap. However, the addition of these conductive elements that reduce electromagnetic radiation can make the assembly process very cumbersome and cause an overall cost increase. Therefore, the main object of the present invention is to provide a computer case that can reduce electromagnetic radiation, and achieve the purpose of reducing electromagnetic light emission without the need to assemble a conductive element separately.
