The utility model is described in further detail with specific embodiment with reference to attached drawing.
With reference to figure 1, Fig. 2.
The utility model embodiment discloses a kind of radio-frequency shielding fence of interior of mobile phone, including shielding box 10, shielding box 10
The edge at top is opened up there are one through-hole, and radiation amplifiers 21 are fixed in through-hole, and 10 top of shielding box is upper to amplify with radiation
The opposite edge of device 21 is fixed with partition panel 22, and partition panel 22 includes the first metallic reflector 221 and the first shielding absorbed layer
222, the first metallic reflector 221 is located at close to the side of radiation amplifiers 21, it is preferred that the first metallic reflector 221 is gold
Belong to aluminium reflecting layer, the first shielding absorbed layer 222 is nanometer composite layer.
In use, antenna for mobile phone 30 is encapsulated into shielding box 10, radiation amplifiers 21 are set upward, and partition panel 22 is close
Human body is set, and the comprehensive signal shielding by mobile phone 30 of shielding box 10 is lived, and because shielding box 10 is provided with through-hole, antenna for mobile phone 30 is sent out
The electromagnetism wave energy gone out is projected by the radiation amplifiers 21 in through-hole, and electromagnetic wave inevitably will appear during through-hole is gathered
Different degrees of loss, radiation amplifiers 21 can effectively improve the power of electromagnetic wave, so that it is guaranteed that mobile phone signal is sufficiently stable；Through
Through-hole is crossed from the angle of divergence of electromagnetic wave that radiation amplifiers 21 are launched than the electromagnetic wave directly launched from antenna for mobile phone 30
The angle of divergence is much smaller, and the electromagnetic wave by the utility model outgoing has good directionality, can effectively control most of electricity
Magnetic wave will not be radiated human body head, and fraction can be reflected and shielded by partition panel 22 to the electromagnetic wave that human body head radiates,
I.e. electromagnetic wave is reflected in the first metallic reflector 221, and small part penetrates the electromagnetic wave of the first metallic reflector 221 by first
It shields absorbed layer 222 and absorbs shielding.
The utility model sets special structure, can assemble electromagnetic wave to a through-hole and be gone out with the minimum angle of divergence
