Abstract
The utility model relates to an electromagnetic radiation protection kit for cell phone, which belongs to electromagnetic radiation protection devices. The model includes a slice of electric conductivity fabric sleeve (1), above which an opening for antenna and an upper cover (3) is arranged and below which a button window is arranged (4). A piece of cover cloth (2) is arranged on the opening for antenna of the sleeve (1). The bake of the sleeve is generally equipped with common cloth (7) on the upper antenna. The surface of the button window (4) on the sleeve is equipped with a rotating outer cover (5), of which (5) the edge is connected with a magnetic sticker (6). The model is characterized in that the structure is novel and the conductivity fabric has good conductive performance. When the incidence of the high frequent electromagnetic wave comes to the surface of a conductor, the electromagnetic wave power can be reflected and adsorbed because of the skin effect. The radiation power is obstructed and the aim of preventing electromagnetic radiation is achieved. Using conductivity cloth for producing mobile phone sleeves, the mobile electromagnetic radiation can be shielded to achieve the aim of no harm to human bodies and other machines.
Description
Technical field
The utility model belongs to the electromagenetic wave radiation protector.
Background technology
For the electromagnet radiation of mobile phone, mainly come from antenna and internal base plate.Wherein antenna belongs to reception and emission, and frequency is single, and complete electromagnetic wave shielding can not be carried out in its tip, otherwise can't converse.The line noise of internal base plate and digital switch frequency noise scope are wide, harm is big, and present phone housing: alloys such as plastics or iron, magnesium etc. still do not possess electromagnetic radiation shielding fully, the equal electromagnetic-radiation-free safeguard functions of all kinds of cell-phone covers such as traditional leather, cloth, plastics yet.Directly at people's head, the consequence of harm is difficult to expect in the radiation of mobile phone.
Summary of the invention
The utility model mobile phone electromagenetic wave radiation protective jacket has the problem of harm to human body with the radiation that solves mobile phone.The technical scheme that the utility model is taked is: comprise sheet type conductive fabric body 1, antenna aperture and loam cake 3 are arranged on it, its positive below has by key window 4, at the antenna aperture place of body 1 common tilt 2 is arranged, the common cloth 7 of the fixing employing in the back side and top antenna place at body, at the enclosing cover 5 that is rotationally connected on the body 1 and on being positioned at by key window 4 surfaces, the fixedly connected magnetic in the edge of this enclosing cover 5 pastes 6.
Advantage of the present utility model is: novel structure, conductive fabric have good conductivity, when frequency electromagnetic waves incides conductive surface, because kelvin effect, electromagnetic wave energy will be reflected and absorb, and emittance is cut off, thereby reaches the purpose that prevents electromagnetic radiation.Adopt conductive fabric to make cell-phone cover, electromagnetic radiation of mobile telephone can be shielded, reach human body and the harmless purpose of other machine.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
Comprise sheet type conductive fabric body 1, antenna aperture and loam cake 3 are arranged on it, its positive below has by key window 4, at the antenna aperture place of body 1 common tilt 2 is arranged, the common cloth 7 of the fixing employing in the back side and top antenna place at body, at the enclosing cover 5 that is rotationally connected on the body 1 and on being positioned at by key window 4 surfaces, the fixedly connected magnetic in the edge of this enclosing cover 5 pastes 6.
Claims (1)
1, a kind of mobile phone electromagenetic wave radiation protective jacket, comprise sheet type conductive fabric body (1), antenna aperture and loam cake (3) are arranged on it, its positive below has by key window (4), it is characterized in that: common tilt (2) is arranged at the antenna aperture place of body (1), at the fixing common cloth (7) that adopts in the back side and top antenna place of body, the enclosing cover (5) that on body (1) is gone up and is positioned at by key window (4) surface, is rotationally connected, the fixedly connected magnetic in the edge of this enclosing cover (5) pastes (6).
