Description
Technical field
The utility model relates to communication equipment manufacturing technical field, in particular to a kind of filter cover board tuning screw is self-locking
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, have excellent temperature stability, high q-factor, small size small cell filter at
To meet the necessary device that 5G communicates the small base station equipment of high density.From conventional filter to novel small cell base station filters
In transition process, the device cover board and adjusting screw rod of traditional filtering and thickness, the width of nut all greatly limit small-sized
Change space and comfort level of the filter in interior design, assembly.Even some positions there is also serious part it
Between interfere with each other.Therefore the scheme of traditional nut lock screw rod for the filter of miniaturization design, assembly and debugging and
It says 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
Equipped with the notch in the thread that can be stuck in thread segment set by tuning screw, the thread segment and cover board of tuning screw are connected by screw thread
It connects, the light bar segment of tuning screw passes through notch set by self-locking reed and is placed in hollow cavity set by resonance shell, and tunes
The axis of the light bar segment of screw and the axis collinear of resonant rod.Although the above-mentioned prior art can only have the item of screw in no nut
Realize that screw is self-locking under part.But since its elastic slice needs to be fixedly welded on the inside of cover board, installation production efficiency is low, it is at high cost,
And it is easily damaged.In addition the structure elastic slice is placed in inside cavity, can generate limitation in internal assembly to filter, and right
Very serious interference is generated in signal tuning.
