Description
Technical field
The utility model relates to communication equipment manufacturing technical field, in particular to a kind of filter tuner structure.
Background technique
Adjusting screw rod is generallyd use on traditional filter cover board, screw rod is pressed on filter cover board by the mode of nut
On.It the use of highdensity network deployment is to realize the 10Gbps of 5G communication with upward peak speed when 4G is to 5G development communication technologies
One of effective means of rate.Dense network is to dispose more low-power small stations in the unit area.The following low-power according to estimates
The density of node will be 10 times or more of present density, so that dense network deployment will improve entire communication network covering.
This not only significantly promotes message capacity, but also with more flexible network deployment and more efficient frequency.
Filter often directly affects entire communication system as the important devices in base station equipment, the superiority and inferiority of performance
The high density base station equipment of the quality of energy, 5G communication also puts forward new requirements filter, i.e., to miniaturization, lighting, height
Frequencyization and low power consumption develop.At this point, it is logical as 5G is met to have excellent temperature stability, high q-factor, the filter of small size
Believe the necessary device of the small base station equipment of high density.From conventional filter into novel base station filter transition process, traditional filter
The device cover board and adjusting screw rod of wave and thickness, the width of nut all greatly limit mini filter interior design,
Space and comfort level when assembly.It even there is also at some positions and interfered with each other between serious part.Therefore tradition
Nut lock screw rod scheme for the design of the filter of miniaturization, assembly and debugging for it is very unreasonable.
The prior art (CN204315692U) discloses a kind of tuner.Including resonance shell and resonant rod, resonant rod
It is placed in hollow cavity set by resonance shell, the top of resonance shell is equipped with cover board, is installed with tuning screw in cover plate
And self-locking reed, tuning screw include thread segment and light bar segment, self-locking reed is fixed on the medial surface of cover board, and self-locking reed
