Description

A kind of radome that prevents electromagnetic leakage
Technical field
The utility model relates to electronic device field, relates in particular to a kind of radome that prevents electromagnetic leakage.
Background technology
At present, the communication apparatus integrated level is more and more higher, circuit devcies such as the power amplifier in the equipment, radio-frequency signal generator, signal generator of intermediate frequency, baseband circuit, power supply are integrated on the circuit board usually, as printed circuit board (PCB) (PCB, Printed Circuit Board) on, constitute integrated circuit, like this, make device miniaturization on the one hand, can come each part in the connecting circuit plate by printed circuit lines on the other hand, wherein, radio-frequency signal generator and power amplifier link together and form radio frequency power amplification module in the integrated circuit.But, can't be connected by printed circuit lines between radio frequency power amplification module and the device antenna, at this moment, use circuit connector to connect with regard to needs, generally select radio frequency connector for use, as microminiature radio frequency (RF) coaxial connector (MMCX, Miniature Microax Rf Coaxial Connector) etc., when radio frequency connector is installed, guarantee that radio frequency connector has good ground connection property.In order to prevent electromagnetic leakage, on radio frequency power amplification module, often need to add a radome, and guarantee to contact between this radio frequency connector and the radome good.
Fig. 1 is shielding case structure schematic diagram of the prior art, and Fig. 2 (a), Fig. 2 (b) and Fig. 2 (c) are respectively front view, right view and the left view of radio frequency connector of the prior art.As shown in Figure 1, radio frequency connector 12 vertically is welded on the PCB11, make a call to one than the big through hole of radio frequency connector 12 external diameters at radome 13 end faces, allow radio frequency connector 12 vertically pass radome 13 end faces, if this through hole and radio frequency connector 12 are without any processing, radio frequency connector 12 can't contact with radome 13.
Prior art mainly adopts the method that the shielding pad is installed at the problems referred to above, a kind of is at conductive shield pad of radio frequency connector 12 covers, make between the connector head (as radio frequency cable) and radome 13 that the shielding pad is crushed on and radio frequency connector 12 joins, to realize electrically contacting between radome 13 and the radio frequency connector 12, the problem that this solution exists is, the external diameter of common radio frequency connector 12 and square ring flange 12-1 limit are tangent, when the shielding pad is enclosed on the radio frequency connector 12, the shielding pad almost is not limited on the ring flange 12-1, cause the shielding pad to be extruded under pressure, meet PCB11, make shielding pad track direct and on the PCB11 contact, though can by the PCB11 track is coated insulating oil prevent from shielding the pad contact with the direct of track, but it is relatively poor to do reliability like this, in case some places are wiped because of carelessness by holiday or insulating oil and are exposed track, just are easy to cause short circuit, damage equipment; The another kind of solution of prior art is that shielding pad is pressed between the radome 13 of the radome 13 of a circuit module and another circuit module, but the prerequisite of this method is must existence can provide the plane that the shielding pad is installed between the radome 13 of two modules, has bigger limitation using.
In sum, existing radome can't with circuit connector between keep well contacting; When adopting the shielding cushion cover on circuit connector, shielding pad compressive deformation directly contacts with PCB, easily causes the equipment short circuit, has bigger application limitation and will shield the method for filling up between the radome that is installed in two circuit modules.
