Choosing a self-locking tuning screw suitable for 5G filter needs to be considered from the following aspects:

dimensions

-Screw diameter: match the mounting hole on the 5G filter. If the screw diameter is too small, it may not provide enough fastening force and affect the stability of the filter; If the diameter is too large, it cannot be installed on the filter smoothly. For example, common 5G filters may use self-locking tuning screws with different diameters such as M2-M8.

-Screw length: The length of the screw needs to be ensured to completely pass through the installation part of the filter, and there is enough thread margin after tightening to ensure the self-locking effect. If the screw length is insufficient, it cannot be effectively fixed; If the length is too long, it may interfere with other components inside the filter.

texture of wood

-Metal material:

-Stainless steel: It has good corrosion resistance and strength, and is suitable for 5G filters under various environmental conditions. Especially in some humid, high-temperature or corrosive gas environments, stainless steel self-locking tuning screws can maintain good performance and are not easy to rust and corrode.

-Alloy steel: with high strength, it can provide greater fastening force and is suitable for 5G filters with high fastening requirements. However, the corrosion resistance of alloy steel may be slightly worse than that of stainless steel, so it needs to be protected according to the specific environment when it is used.

-Non-metallic materials (special requirements): In some cases where signal transmission is extremely demanding and metal interference needs to be avoided, self-locking tuning screws made of non-metallic materials, such as high-performance plastics, can be selected. However, the strength and high temperature resistance of nonmetallic screws may be insufficient, which needs to be weighed according to the specific situation.

Self-locking performance

-Self-locking structure: Different self-locking tuning screws have different self-locking structures, such as thread shape and notch design. When selecting, it is necessary to ensure that the self-locking structure is reliable, which can always maintain a good self-locking effect during the working process of the 5G filter and prevent the screw from loosening due to vibration, temperature changes and other factors.

-Self-locking force: Excessive self-locking force may lead to difficulties in installing and disassembling screws, which will affect the production efficiency and maintenance convenience of the filter; If the self-locking force is too small, it can not meet the fastening requirements of the filter. Therefore, it is necessary to select screws with appropriate self-locking force according to the actual needs of 5G filters.

Frequency characteristics: The frequency characteristics of the self-locking tuning screw also need to be considered because the 5G filter has strict requirements on frequency selection and signal filtering. The material and structure of the screw will affect its performance at high frequency, so the screw with the least interference to the transmission of 5G signal should be selected to ensure that the performance of the filter will not be affected.

Temperature adaptability: 5G filters may work in different temperature environments, so self-locking tuning screws need to have good temperature adaptability. In the high temperature environment, the screw cannot be softened and deformed; In the low temperature environment, the strength and self-locking performance of the screw can not be affected.

Accuracy grade: The tuning accuracy of 5G filter is required, so the accuracy grade of self-locking tuning screw also needs to match it. High-precision screws can ensure that the parameters of the filter can be adjusted accurately in the tuning process and improve the performance of the filter. For example, the thread accuracy and head size accuracy of screws need to meet certain standard requirements.
