Specific embodiment
To make the technical problem to be solved in the present invention, technical scheme and advantage clearer, below in conjunction with tool
Body embodiment and accompanying drawing are described in detail.
A kind of radio-frequency shielding fence and terminal are the embodiment of the invention provides, is solved in smart mobile phone due to screen
Lid poor flatness is covered so that shield effectiveness is poor, so as to each radio system is mutually dry in causing smart mobile phone
The problem disturbed.
The radio-frequency shielding fence of the embodiment of the present invention, is applied to terminal, the radio-frequency shielding fence and the end
The screening cover connection at end, as shown in figure 1, the radio-frequency shielding fence includes：
Printing board PCB mainboard 1, is provided with least one radio circuit 2 on the PCB main board 1,
And the surrounding of each radio circuit 2 is provided with dew copper region 3；
Be arranged at the multiple conducting foam shell fragments 4 on the dew copper region 3, the conducting foam shell fragment 4 with
The screening cover connection of the terminal.
Wherein, the radio circuit 2 can be specially the modules such as base band, radio frequency, power supply.
The radio-frequency shielding fence of the embodiment of the present invention, it is appropriate to be reserved in the radio circuit surrounding of PCB main board
Dew copper region, and multiple conducting foam shell fragments are set on dew copper region, dew copper region passes through the conducting foam
Spring realize with the connection of screening cover, so as to solving almag screening cover because flatness itself is bad or
Person fixes the bad problem of shield effectiveness caused by the pressure difference of mainboard due to screw, so solve by
The problem of radio system interference caused by the shielding of aluminum current magnesium alloy enclosure is bad.
Further, multiple conducting foam shell fragments 4 along the radio circuit surrounding dew copper region 3
Equidistantly distributed, in a particular embodiment of the present invention, due between two neighboring conducting foam shell fragment 4
Spacing d is smaller, and shield effectiveness is better, but relatively costly, if between two neighboring conducting foam shell fragment 4
Spacing d is too big, though can reduces cost, shield effectiveness can be influenceed, it is preferable that the two neighboring conduction
The distance between foam shell fragment 4 is in the range of 2mm-5mm.
The radio-frequency shielding fence of the embodiment of the present invention, the length of each conducting foam shell fragment 4 is 2mm,
