[embodiment]
With reference to figure 1-Fig. 4, the utility model first embodiment provides a kind of cavity body filter, comprises a resonant cavity, and cavity body filter mainly comprises cavity 110, cover plate 130, resonant column 150, output port connector 170, tap sheet 190 and debugging screw rod 210.
Cavity 110 one end open, cover plate 130 covers the opening of cavity 110, cavity 110 has the base plate 113 parallel with cover plate 130, resonant column 150 is fixed on base plate 113 by the first screw 230, base plate 113 is provided with the boss 115 to cavity 110 internal protrusion, and boss 115 has hole slot 116 for accommodating the tip of the first screw 230.
Output port connector 170 passes cover plate 130 and is fixedly attached to cover plate 130, and along chamber, dark direction extends from cover plate 130 to base plate 113 output port connector 170.Tap sheet 190 is installed to cover plate 130 and is positioned at cavity 110, more particularly, tap sheet 190 has the flat part 192 being parallel to resonant column 150 and the first kink 194 and the second kink 196 vertically bent in opposite direction at the two ends of flat part, first kink is connected to cover plate 130 by the second screw 240, the end of the second kink is welded to output port connector 170, and tap sheet 190 is for coupled resonance post 150.Accordingly, in the chamber of output port connector 170, have can for the plumb joint of welding tap sheet 190 for end.
Debugging screw rod 210 passes cover plate 130 in dark direction along chamber, the first end 210a of debugging screw rod 210 is outside cavity 110, debugging screw rod 210 is installed to cover plate 130 by nut 220, and debugging screw rod 210 can be regulated to stretch into the degree of depth of cavity 110 by rotating nut 220, the first end 210a of the debugging screw rod 210 after adjustment may expose cover plate outside or not expose, and second end of debugging screw rod 210a stretches to cavity.Along chamber, dark direction has hole to resonant column 150, for making the second end 210b of debugging screw rod 210 stretch into, to increase the adjustment surplus of debugging screw rod 210, thus reaches the object of the adjustable range improving filter frequencies.
Because output port connector 170 and tap sheet 190 are all arranged on cover plate 130, relative to the existing mode being installed to cavity 110, volume of part part kind that is little, that use is few, take volume less, concerning the design of filter itself, more can make full use of spatial volume, formed and arrange chamber layout more flexibly.It is more obvious that this advantage embodies when cavity 110 filter comprises multiple resonant cavity.
In a further embodiment, the cavity body filter that the utility model provides comprises multiple resonant cavity, and the plurality of resonant cavity correspondence has one or more cover plate, output port connector and tap sheet.As output port connector needs shielding, can increase between output port connector and cover plate and shield cushion block with practical function.
For the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
