Communication technology is changing with each passing day. With $, people and The distance between people is getting closer and closer, and the wired method is used, but the wireless transmission affects the interference problem during communication. The wired transmission wheel is still the most current communication. However, the wired transmission is the transmission path of electronic signals.

The dense ceramic correction system 21 is lowered until the middle of the rotation. The power stroke wheel is rotated again to make the correction operation. Into the inner hole of the optical fiber ferrule 3

Take out the optical fiber ferrule 3, and then place a new optical fiber ferrule 3 to be calibrated on the metal housing positioning system 2 2. To purify the surface of the ceramic calibration shaft, a high-pressure source system 23 (such as a high-pressure blunt gas source) is used to purify the dust or metal shavings on the surface of the calibration shaft. Repeat the above operation until the laser caliper 2 4 detects that the surface tolerance dimension of the calibration shaft is invalid. According to the experimental results of the above steps, when the optical fiber ferrule 3 inner hole corrected with 2 positive axis 16 is more accurate than the positive axis of the second metal plate (as shown in the fifth figure), the ceramic The outside of the correction axis 16 is 2.5125mm, and the diameter of the inner hole of the optical fiber ferrule 3 is 2.498 1 mm. The plastic of the edge seal is q 〇72525mm (about 7 / zm). After the metal rebounds, Actually, the variable zone is 0 · 0 045 5mm (about 4 · 5 // m). The rebound rate of zinc-plated zinc material is 6% ~ 7%; while the optical fiber ferrule (SM type) 3 has an outer diameter of 2.4. 49 9mm, the margin of the optical fiber ferrule 3 after correction is 0.005min (4 ^ 5 βΙΆ); from the above experimental results, it is shown that the effective control of the outer diameter of the ceramic correction shaft 16 can effectively control the optical fiber ferrule Margin of inner hole in circle 3. Secondly, from the perspective of service life, the hardness of the ceramic material (above HV1000) is much higher than that of the nickel-plated zinc casting (below HV200), so the use of the ceramic calibration shaft 16 can be used for this application. The experimental results show that the number of times the metal calibration shaft is used is about 1 to 2000 times, which means that it cannot be used due to excessive wear, and it also has the disadvantage of peeling off the nickel plating layer.
