Suzhou Maite Technology Introduction: What are the advantages of the application of self-locking tuning screws for 5G filters?

The core advantages of the self-locking tuning screw of 5G filter are: fast debugging, long-term stability, mutual adjustment, excellent cost and maintenance-free, which perfectly meets the requirements of high frequency, high reliability and large-scale deployment of 5G base stations.

First, the advantages of machinery and debugging efficiency

Nut-free, one-step in place: self-locking structure (expansion groove/elastic retainer/dislocation thread), which can be locked when screwed in, without additional locking nut, and the debugging process is halved.

Debugging efficiency is greatly improved: when tuning, the position can be locked by turning the screw directly, and there is no secondary locking/locking operation, so the production line has a faster beat and the labor cost is lower.

Structure simplification and weight reduction: the whole weight of the filter is reduced by eliminating nuts and gaskets, which is more conducive to the lightweight and heat dissipation of the base station.

Good assembly consistency: the thread and self-locking structure are integrated, and the assembly error is smaller, which is convenient for automatic production line batch production.

Second, long-term stability and reliability (just needed by the core of 5G base station)

Never loose, anti-vibration: self-locking is realized by radial expansion force/friction force/thread dislocation, and the position will never drift under vibration, temperature change and wind load of the base station, and the resonance frequency will be stable for a long time.

Strong temperature drift suppression: metal/elastic material matching design, expansion when heated and contraction when cooled, and minimal frequency drift in outdoor environment of-40℃~85℃.

Impact and aging resistance: the self-locking structure is mechanically self-locking rather than relying on glue/elastic sheet, which is aging-resistant and impact-resistant, and meets the requirements of 10 years+life of the base station.

Post-maintenance-free: after the base station is opened, there is no need for patrol inspection, re-tightening and re-adjustment, which greatly reduces the operation and maintenance cost.

Third, RF performance advantages (5G high frequency key)

Low intermodulation (IMD): reliable contact, no loose gap and even current distribution, which significantly reduces passive intermodulation and improves the sensitivity and anti-interference ability of 5G Massive MIMO system.

Low insertion loss: conductive material (copper/silver plating)+close contact, low RF loss and purer signal transmission.

High frequency stability: accurate position locking, good consistency and repeatability of resonance frequency, and easier control of batch consistency.

IV. Cost and Technological Advantages

Material cost reduction: nuts, gaskets and locking glue are omitted, and the BOM cost of a single filter is reduced.

Simplification of processing and assembly: fewer parts, fewer processes, higher automation rate and lower defective rate.

Convenient repair and replacement: no need to remove the nut, it can be replaced by screwing it out directly, and the maintenance is more efficient.

V. Advantages of environmental adaptability

Salt spray resistance and corrosion resistance: the surface is plated with silver/nickel, which has passed the salt spray test for 2000 hours and is suitable for coastal, high humidity and industrial polluted environment.

Wide temperature stability: the self-locking force is stable in the range of -40℃~85℃ and does not fluctuate greatly with the temperature.
