the specific workflow of the fifth embodiment is different from that of the fifth embodiment in that, before screwing the screw cap 5 into the protecting tube 41, the rubber sealing ring is first put into the screw cap 5, and the rubber sealing ring is located at one end of the screw cap 5 far away from one side of the communication body 1, then, after screwing the screw cap 5 into the protecting tube 41, the inner wall of the screw cap 5 presses the plurality of first arc-shaped elastic sheets 42, so that the pressing block 61 moves to one side close to the outer ring of the optical fiber 3, locks the position of the optical fiber 3, and when dust is located at the position of the rubber sealing ring 101 and gradually accumulated and acts on the rubber sealing ring 101, the rubber sealing ring moves to one side close to the rubber sealing ring, so that the rubber sealing ring is tightly attached to the outer ring of the optical fiber 3, moisture in the air is prevented from entering through a gap between the optical fiber 3 and the screw cap 5, and finally entering the communication body 1, so that the communication body 1 is protected, and the stability of the communication of the optical fiber 3 is ensured.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
