Embodiment
Consult Fig. 1, be depicted as a kind of radome of the present invention and be positioned over stereogram on circuit board 11, described circuit board 11 comprises demodulator module 12, cover body 13 and baffle plate 14.Demodulator module 12 comprises a module joint 121.
Consult Fig. 2, be depicted as the explosive view of cover body 13 and baffle plate 14, baffle plate 14 is fixed on cover body 13.
Consult Fig. 3, shown baffle plate 14 comprises a front panel 141 and two fixed heads 15, and the two ends bending of fixed head 15 front panel 141 is formed, and fixed head 15 is vertical with front panel 141, two fixed heads 15 are respectively equipped with two fixing salient points 151, fixing salient point 151 is in being arranged above and below.A circular window 143 is provided with in the centre position of front panel 141, the edge of window 143 extends the extended surface 21 of a truncated cone-shaped to the direction contrary along fixed head 15, the cross section of extended surface 21 is circles, extended surface 21 and baffle plate 14 are not completely vertical, and the diameter of a circle that the cross section of extended surface 21 is formed is more and more less along the direction extended.Described extended surface 21 is provided with some grooves 211 and extended surface 21 is cut into some parts, the elasticity of extended surface 21 can be increased like this.Window 143 is used for the module joint 121 of accommodating described demodulator module 12, extended surface 21 encases module joint 121, and have certain pressure to module joint 121, make the gap between extended surface 21 and module joint 121 very little like this, play good shield effectiveness.The surrounding of window 143 is provided with a projection 144.Protruding 144 fully can contact with cover body 13 when baffle plate 14 coordinates with cover body 13, reduce the contact gap of baffle plate 14 and cover body 13.
Consult Fig. 4, cover body 13 is roughly the shell structure of a cuboid, and one of them face is untight.Described demodulator module 12 encases by cover body 13, and meanwhile, cover body 13 is fixed on circuit board 11, and cover body 13 is provided with a preposition face 131 and two sides 132, and preposition face 131 is vertical with two sides 132 respectively.Wherein preposition face 131 is provided with the opening 135 of a U-shaped, is used for holding on module joint 121, two sides 132 on demodulator module 12 being respectively equipped with two fixing holes 1321.The edge of two sides 132 is provided with some fixing feet 134, for cover body is fixed on circuit board 11.
Consult Fig. 2, fixed head 15 on baffle plate 14 slides along the side 132 of cover body 13, and fixing salient point 151 gets into fixing hole 1321, and the front panel 141 of baffle plate 14 touch the preposition face 131 of cover body 13, protruding 144 help better to contact between the two, and baffle plate 14 is fixed in cover body 13.
