Description

Technical Field

[0001] The utility model relates to the field of optical fibers, in particular to an optical fiber end protective sleeve. Background Art

[0002] In the field of optical fiber communication, the optical fiber dustproof tail sheath is an important device for low-loss, low-reflection connection between two sections of optical fiber. It prevents the optical fiber from breaking when it is subjected to external force, and also plays an auxiliary role in dust prevention. According to different usage scenarios, the optical fiber dustproof tail sheath can be divided into SC mesh tail sheath, ST mesh tail sheath, FC mesh tail sheath, SE tail sheath, etc. These tail sheaths are usually covered with dust caps before optical fiber connection to prevent dust from entering.

[0003] For example, the Chinese utility model patent with application number: 201920067355.0, the name of the utility model creation is a mesh tail sheath, which discloses "including a base and a sheath part connected together and maintained in communication, and the end faces of the base and the sheath part are respectively provided with positioning holes and wire entry holes, and the number of the positioning holes and the number of the wire entry holes are two and one respectively." The above technical purpose is: to enable the two-core cable to merge naturally when inserted to avoid the problem of different lengths. The number of positioning holes is two, which is convenient for separating the two core wires of the two-core cable, so as to fix the plug-in width of the duplex connector, and then position the duplex interface. Avoid the problem of connection plug-in size deformation caused by the unfixed swinging of the duplex interface, which leads to the phenomenon of unsmooth connection insertion and unstable data connection. However, the fiber optic connector is not limited to the round shape. For example, the Chinese invention patent with application number: 93117783.9, the utility model creation name is multi-channel fiber optic connector. In the invention patent, the fiber optic connector is flat. At this time, the above-mentioned invention patent of the mesh tail sheath cannot effectively fix the fiber optic connector, and the invention patent of the mesh tail sheath is difficult to connect with the dust cap after fixing the fiber optic connector. Without the protection of the dust cap, dust and moisture are easily accumulated on the fiber optic connector, affecting the normal operation of the optical fiber. Utility Model Content
