Cavity body filter 100 includes multiple single-chambers 110, and resonant rod 111, Mei Gedan can be arranged in each single-chamber 110
Chamber 110 is all separated by the cavity wall 120 of cavity body filter 100.Wherein, it can be set between two adjacent single-chambers 110
Fly bar 130, flying bar 130 may be mounted on the cavity wall 120 between two adjacent single-chambers 110, wherein flying the both ends of bar 130
It is plugged in the two single-chambers 110 respectively.
In the present embodiment, insulation fabric part 140 is additionally provided between resonant rod 111 and winged bar 130, by winged bar 130
Upper setting insulation fabric part 140 can make to fly bar 130 and resonant rod 111 is in state of insulation, meanwhile, when installing winged bar 130,
The two sides of insulation fabric part 140 abut respectively flies bar 130 and resonant rod 111, therefore can to fly bar 130 and resonant rod 111
Between spacing may remain in certain range, this is allowed for during producing cavity body filter 100, is not needed anti-
The size and installation situation of the whole winged bar 130 of polyphony are just avoided that winged 130 assembling process of bar is poor because of consistency caused by installation error
The problem of, not only shorten 100 debug time of cavity body filter, improve the First Pass Yield of debugging process, product quality is also more
It is reliable and stable.
In the present embodiment, insulation fabric part 140 can be arranged in the end for flying bar 130, and wherein insulation fabric part 140 can glue
It is attached to one end of winged bar 130, or can also be matched with one end grafting of winged bar 130.
When insulation fabric part 140 is matched with one end grafting of winged bar 130, it can be arranged on insulation fabric part 140 and insert
Slot 141 is set, the one end for flying bar 130 is inserted in insertion slot 141 to be matched with 140 grafting of insulation fabric part.
Further, since winged bar disk 131 would generally be arranged in the both ends for flying bar 130, winged bar disk 131 can also be inserted in
It is interior to be matched with 140 grafting of insulation fabric part.In the present embodiment, the shape of insertion slot 141 can match with winged bar disk 131.
Further referring to Fig. 2, cavity body filter 100 further includes deck 150, wherein deck 150 be mounted on two it is adjacent
Single-chamber 110 between cavity wall 120 on, mounting hole 151 is provided on deck 150, fly bar 130 intermediate position be arranged is pacifying
It fills in hole 151.Therefore, by the way that deck 150 to be mounted on cavity wall 120, winged bar 130 can be installed to cavity wall 120
On, so that the both ends for flying bar 130 are plugged respectively in two adjacent single-chambers 110.
Wherein, on the axial direction along mounting hole 151, flying bar 130 can be slided in mounting hole 151 in deck 150
Matching, and an insulation fabric part 140 can be set in the both ends for flying bar 130.Therefore, when installing winged bar 130, can pass through
Fly bar 130 to slide in mounting hole 151, thus between balancing between winged 130 both ends of bar and respectively corresponding resonant rod 111
Away from so that the spacing flown between the winged bar disk 131 at 130 both ends of bar and respectively corresponding resonant rod 111 is all satisfied
Preset requirement, therefore can be convenient the installation and debugging of winged bar 130.
In the present embodiment, after winged bar 130 is completed to install, the insulation fabric part 140 for flying the setting of 130 both ends of bar can will fly
The position of bar 130 is fixed.That is, the two sides for flying the insulation fabric part 140 at 130 both ends of bar abut resonant rod 111 and winged bar disk respectively
131, so as to which the position of winged bar 130 is fixed in the axially direction along winged bar 130.
Further, insulation fabric part 140 is made of insulating material, in one embodiment, insulation fabric part 140
Material is ambroin, and the insulation effect of ambroin is good and from a wealth of sources, help to obtain preferable insulation effect and reduction
Cost.Specifically, ambroin is one of polytetrafluoroethylene (PTFE), phenolic resin, acid imide plastics or compound.Implement at one
In mode, ambroin is polytetrafluoroethylene (PTFE), and polytetrafluoroethylene (PTFE) is light and more easily molded, and flies the shape of bar disk 131 with basis
Produce the insulation fabric part 140 of correspondingly-sized and shape.Further, the size of insulation fabric part 140, which is not less than, flies bar disk 131
Size, that is to say, that winged bar disk 131 is completely covered in insulation fabric part 140.Certainly, it is completely covered in insulation fabric part 140 winged
Under the premise of bar disk 131, the size of insulation fabric part 140 can be greater than the size for flying bar disk 131, not need strictly to limit insulation
The size of structural member 140 is conducive to improve production efficiency.
Further, fly between bar disk 131 and resonant rod 111 since insulation fabric part 140 is located at, namely be located at and fly
Between bar disk 131 and resonant rod 111, therefore, the thickness of insulation fabric part 140, which is not more than, to fly between bar disk 131 and resonant rod 111
Distance.It certainly, can be with from the material category angle for reducing production cost, improving production efficiency and insulation fabric part 140
The thickness of insulation fabric part 140 is defined.Such as, the material of insulation fabric part 140 is polytetrafluoroethylene (PTFE), with a thickness of
0.5mm.In other examples, insulation fabric part 140 can also be made of elastic insulating material, can be by insulation system
Part 140 is arranged in the thickness flown between bar disk 131 and resonant rod 111 and is set as slightly larger than between winged bar disk 131 and resonant rod 111
Spacing can occur elastic deformation by insulation fabric part 140 therefore when installing to winged bar 131, and by winged bar
131 and resonant rod 111 position it is relatively fixed.
Further referring to Fig. 1, the single-chamber 110 of cavity body filter 100 provided in the present embodiment is two, at other
Embodiment in, the number of the single-chamber 110 of cavity body filter 100 may be arranged as multiple, such as the list of cavity body filter 100
The quantity of chamber 110 can be set to 2-8, e.g., 2,4,6 or 8 etc..And all may be used between two adjacent single-chambers 110
Winged bar 130 and insulation fabric part 140 as previously described is arranged.
In the present embodiment, cavity body filter 100 further includes tuning plug 160 and cover board (not shown), wherein tuning plug
160 one end is inserted in the resonant cavity of resonant rod 111, and cover plate is used to cover the opening of all single-chambers 110, so that cavity
Filter 100 forms the cavity space of sealing, and previously described resonant rod 111 flies bar 130, insulation fabric part 140 and deck
150 are arranged in the cavity space of sealing.Wherein, tuning plug 160 may be mounted on cover board.
Further, present invention also provides a kind of communication devices, and wherein communication device may include as previously described
Cavity body filter 100, communication device can be communication base station, and communication base station may include antenna and the cavity connecting with antenna filtering
Device 100.
In conclusion cavity body filter includes: this application discloses a kind of cavity body filter and using its communication device
Multiple single-chambers 110, wherein cavity body filter further include: fly bar 130, the adjacent cavity wall of the multiple single-chamber 110 is set
