Description
Technical field
The utility model belongs to the coupling field for being applicable wave filter, and in particular to integrated coupling.
Background technology
Along with the high speed development of electronic technology, electromagnetic environment goes from bad to worse, and substantial amounts of communication and electronic equipment are this
Normal work is difficult in electromagnetic environment.On the other hand, electronic equipment increases sharply, and further causes the evil of electromagnetic environment
Change, thus the modern times adverse circumstances, be problem that operator must face from anti-interference filtration device.In recent years, in 4G nets
In the case that network is developed rapidly, interference of the mobile 1800MHz to other operators is larger, general of the wave filter of domestic market
Intermodulation is poor, and interference free performance is inadequate, and the transmission coupling of general filter on the market is with copper wire welding, lost labor
Cost, intermodulation is bad.
A kind of coupled structure of patent (notification number is CN105514532A), discloses a kind of coupled structure, including housing, coupling
Heal up joint, radio-frequency joint, coupling bar and Supporting Media set.Simple structure of the present invention, size is small, and is advantageously integrated and is arranged on conjunction
On road device, duplexer, wave filter, electric bridge or joint.But transmission coupling at present is one copper cash of welding on resonant rod, then
The other end of copper cash is connected on joint, is welded together to reach the effect of signal transmission, this transmission coupling with scolding tin
The drawbacks of conjunction is exactly design cost high, and lost labor, intermodulation is unstable.
Therefore it is badly in need of simple structure, cost is relatively low, intermodulation percent of pass integrated coupling high.
Utility model content
In order to the transmission coupling intermodulation percent of pass for solving wave filter is low, cost of labor problem high, mesh of the present utility model
Be to provide integrated coupling, intermodulation percent of pass high advantage relatively low with cost.
The utility model provides following technical scheme：
Integrated coupling, including coupling and cavity, the cavity are provided with axis hole, the coupling insertion
To in the axis hole, the coupling includes joint, joint conductor, coupling bar and medium socket, the joint and the joint
Conductor is connected, and the joint conductor and the coupling bar are integrally formed, and the medium socket is in the joint conductor and the coupling
The periphery of rod.
Preferably, the medium cover material is polytetrafluoroethylene (PTFE), ethylene fluoride propylene copolymer or crosses fluoroalkyl compound
One or more, there is wear resistance, corrosion resistance.
Preferably, the coupling bar material is copper alloy or aluminium alloy, and microwave signal is transmitted by the coupling bar, had
Intermodulation percent of pass is high, the advantage of strong anti-interference performance.
The beneficial effects of the utility model are：
1st, simple structure, cost reduction.
2nd, strong anti-interference performance, can suppress bottom and make an uproar, and the system bottom of base station is made an uproar reduces 8dB.
3rd, intermodulation percent of pass is high.
Brief description of the drawings
Accompanying drawing is used for providing being further understood to of the present utility model, and constitutes a part for specification, with this practicality
New embodiment is used to explain the utility model together, does not constitute to limitation of the present utility model.In the accompanying drawings：
Fig. 1 is the utility model structural representation；
Fig. 2 is scheme of installation；
Marked in figure：1st, coupling；2nd, cavity；3rd, axis hole；11st, coupling；12nd, joint conductor；13rd, couple
Rod；14th, medium socket.
Specific embodiment
As shown in Figure 1-2, integrated coupling, including coupling 1 and cavity 2, cavity 2 are provided with axis hole 3, coupling
Joint 1 is inserted into the axis hole 3, and coupling 1 includes joint 11, joint conductor 12, coupling bar 13 and medium socket 14, joint
11 are connected with joint conductor 12, and joint conductor 12 and coupling bar 13 are integrally formed, and medium socket 14 is in joint conductor 12 and coupling bar
13 periphery.
There is gap, coupling bar 13 forms larger electric capacity, joint conductor 12 with cavity 2 between medium socket 14 and axis hole 2
It is integrally formed with coupling bar 13, after reducing welding, intermodulation percent of pass can be improved, and can reduce cost of labor.
Method of work of the present utility model：The rank of 1800M anti-interference filters 3 mutually mixes up, integrally formed joint conductor 12
Connected with coupling bar 13 and resonant rod, wave filter intermodulation percent of pass is high, strong anti-interference performance, and bottom can be suppressed and made an uproar, make base station
System bottom make an uproar reduction 8dB.
Preferred embodiment of the present utility model is the foregoing is only, the utility model is not limited to, although ginseng
The utility model is described in detail according to previous embodiment, for a person skilled in the art, it still can be with
Technical scheme described in foregoing embodiments is modified, or equivalent is carried out to which part technical characteristic.It is all
Within spirit of the present utility model and principle, any modification, equivalent substitution and improvements made etc. should be included in this practicality
Within new protection domain.
