Description
Technical field
This utility model relates to a kind of communication filtering technique, especially relates to a kind of cavity body filter.
Background technology
Cavity body filter the communications field such as is widely used in as a kind of signal of communication and frequency selection device, and can filter
Clutter in addition to communication signal frequency or interference signal, wherein coaxial cavity filter generally comprises cavity, cover plate and cavity
The resonator cavity formed with cover plate, is provided with the modules such as resonant column in resonator cavity.
Wave filter needs to use adapter connector and other module to be attached transmitting signal, reaches signal intercommunication interconnection
Purpose, the most conventional adapter is 4.3-10 adapter, and traditional adapter connector need to be fixed by screws in wave filter
On cavity, being contacted with cavity by intermodulation ring, as disclosed in China Patent Publication No. CN101924308, a kind of wave filter is with penetrating
Frequently coaxial connector, in the program, union joint is connected with the cavity of wave filter by the intermodulation set being disposed thereon, and the program can
To reduce Intermodulation Interference to a certain extent, but owing to the use environment of wave filter is more and more severe, salt fog requires more and more higher, institute
Being required for dusting with housing surface, due to technologic problem, the cavity thickness that dusts is difficult to control to, and causes adapter to connect with cavity
Touch undesirable, the biggest to intermodulation effects, affect the intermodulation effect of wave filter.
Utility model content
The purpose of this utility model is to overcome the defect of prior art, it is provided that a kind of cavity body filter, by the company of improvement
Connect the connected mode of device and filter cavity, increase contact area, improve intermodulation effect.
For achieving the above object, the utility model proposes following technical scheme: a kind of cavity body filter, including cavity, lid
Plate and adapter, described cover plate is fastened on described cavity, and the sidewall of described cavity is formed installing hole, described adapter riveting
It is connected in described installing hole.
Preferably, described adapter includes that Plug Division, pressure contact portion and flange, described flange are arranged on described Plug Division and institute
Stating between pressure contact portion, described pressure contact portion is riveted in described installing hole.
Preferably, described pressure contact portion outer surface is provided with annular knurl in a circumferential direction.
Preferably, described pressure contact portion and described installing hole interference fit.
Preferably, described adapter is radio frequency (RF) coaxial connector.
The beneficial effects of the utility model are: this utility model by adapter connector is directly pressed inside cavity,
Adapter pressure contact portion outer surface is contacted with the surface of installing hole on described cavity, considerably increases contact area, evade
Screw connects heavy because of the thickness impact on contact of dusting, and is substantially improved the intermodulation effect of wave filter, and then raising intermodulation is once led to
Cross rate.

Detailed description of the invention
Below in conjunction with accompanying drawing of the present utility model, the technical scheme of this utility model embodiment is carried out clear, complete
Description.
As it is shown in figure 1, described wave filter 1 includes cavity 2, cover plate 3 and adapter 4, described cavity 2 and described cover plate 3 are close
Envelope forms resonator cavity, and the sidewall of described cavity 2 is formed installing hole 21, and described adapter 4 rivets mutually with described installing hole 21,
Fig. 1 shows and is crimped with two adapters on cavity 2, and wherein, an adapter is in confined state, and another adapter is
Assemble, realized the communication connection of intra resonant cavity part and other communication module by adapter 4, owing to adapter 4 is directly pressed
Riveting, inside cavity, considerably increases contact area, improves the intermodulation effect of wave filter.
Shown in Fig. 2, described adapter 4 includes that Plug Division 41, pressure contact portion 42 and flange 43, described flange 43 are arranged on
Between described Plug Division 41 and pressure contact portion 42, described pressure contact portion 42 outer surface is provided with annular knurl 44, described pressure in a circumferential direction
Connecing portion 42 and described installing hole 21 interference fit, described pressure contact portion 42 is riveted/is crimped in the installing hole 21 of cavity, after riveting
Described flange 43 is resisted against on the sidewall of described cavity, forms location, and described Plug Division 41 is used for and external communication module grafting.
Specifically, the adapter 4 in this utility model is radio frequency (RF) coaxial connector, and described radio frequency (RF) coaxial connector is by interior
To being outside equipped with inner wire, dielectric and outer conductor, it is achieved penetrating between wave filter external module resonant cavity internal module
Frequency communication, can be widely used for coaxial cavity filter.
This utility model is by directly pressing adapter connector inside cavity so that adapter pressure contact portion outer surface with
The surface contact of described cavity installing hole, considerably increases contact area, has evaded screw and has connected because the thickness that dusts is to contact
Impact, is substantially improved the intermodulation effect of wave filter, and then improves intermodulation First Pass Yield.
Technology contents of the present utility model and technical characteristic have revealed that as above, but those of ordinary skill in the art still may be used
All replacements without departing substantially from this utility model spirit and modification can be made based on teaching of the present utility model and announcement, therefore, this
Utility model protection scope should be not limited to the content disclosed in embodiment, and should include various without departing substantially from replacement of the present utility model
And modify, and contained by present patent application claim.
