[0027] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See Figures 1 to 4 As shown, an embodiment of the present invention provides an air-blown optical cable assembly 10, which includes an outer tube structure 100 and an optical fiber structure 200; an accommodating cavity 111 is provided inside the outer tube structure 100, and the inner wall of the accommodating cavity 111 is provided with a guide portion 120; the outer wall of the optical fiber structure 200 is provided with a guide groove 211, the optical fiber structure 200 is passed through the accommodating cavity 111, and the guide portion 120 slides in conjunction with the guide groove 211.

[0029] In the air-blown optical cable assembly 10 of this embodiment, by providing a guide portion 120 in the outer tube structure 100 to cooperate with the guide groove 211 of the optical fiber structure 200, the optical fiber structure 200 can be guided during the air-blowing conveying process of the optical fiber structure 200, thereby reducing the friction between the optical fiber structure 200 and the inner wall of the accommodating cavity 111, thereby improving the conveying efficiency and smoothness of the optical fiber structure 200. Specifically, the outer tube structure 100 can be a HDPE tube.

[0030] Specifically, the optical fiber structure 200 includes a sheath 210 and an optical fiber 220 . The optical fiber 220 is inserted into the sheath 210 . The guide groove 211 is provided on the outer wall of the sheath 210 . The sheath 210 is slidably matched with the guide portion 120 .

[0031] In this embodiment, the optical fiber 220 can be a 1-24 core single-mode multimode optical fiber, and the sheath 210 can be made of HDPE, LSZH, or PVC. By setting the sheath 210 to wrap the optical fiber 220, the optical fiber 220 can be protected. At the same time, during the transportation of the optical fiber structure 200, the sheath 210 is in contact with the outer tube structure 100, which can avoid damage to the optical fiber 220.

[0032] Furthermore, the optical fiber structure 200 further includes at least two reinforcement members 230 . The reinforcement members 230 are disposed in the jacket 210 and are arranged parallel to the optical fiber 220 .

[0033] In this embodiment, the reinforcement 230 can be a non-metallic reinforcement such as a glass fiber non-metallic plastic rod. By arranging the reinforcement 230 that cooperates with the optical fiber 220 inside the sheath 210, the overall strength of the optical fiber structure 200 can be effectively improved. When the optical fiber structure 200 is subjected to external force, it can be supported by the reinforcement 230 to avoid damaging the optical fiber 220.

[0034] Specifically, the outer tube structure 100 also includes a tube body 110, the accommodating cavity 111 is arranged inside the tube body 110, the guide part 120 is connected to the tube body 110, and the outer peripheral wall of the tube body 110 is closed; the guide groove 211 is a T-shaped groove, and the cross section of the guide part 120 is T-shaped.

[0035] In this embodiment, the tube body 110 and the guide portion 120 are integrally formed, and the guide portion 120 is located inside the accommodating cavity 111 of the tube body 110. When the optical fiber structure 200 moves relative to the outer tube structure 100, the guide portion 120 cooperates with the guide groove 211 to guide the movement of the optical fiber structure 200. Furthermore, because the tube body 110 is a tube structure with a closed outer wall, the air path can be sealed, thereby achieving air-blown conveying. Specifically, the overall size of the T-shaped guide groove 211 is smaller than the guide portion 120 by 0.2-0.4 mm, ensuring smooth cooperation between the outer tube structure 100 and the optical fiber structure 200 and reducing friction.

[0036] Furthermore, the number of the guide grooves 211 and the guide portions 120 is at least two groups, and at least two groups of guide grooves 211 and guide portions 120 are arranged around the optical fiber structure 200 .

[0037] In one embodiment, the guide portion 120 and the guide groove 211 are symmetrically arranged on opposite sides of the optical fiber structure 200. In this arrangement, when the optical fiber structure 200 is connected to the outer tube structure 100, it can be ensured that the optical fiber structure 200 is subjected to uniform force inside the outer tube structure 100, thereby improving the stability of the movement of the optical fiber structure 200.

[0038] Specifically, the optical fiber structure 200 further includes a tearing groove 212 , which is connected to the guide groove 211 and is located inside the guide groove 211 .

[0039] By providing the tearing groove 212 on the inner side of the guide groove 211 , when the optical fiber structure 200 needs to be torn, the tearing distance of the sheath 210 can be reduced, thereby improving the convenience of tearing the sheath 210 .

[0040] In one embodiment, the angle of the tear groove 212 is 15°. It is understood that by setting the angle of the tear groove 212 to 15°, the two side walls of the tear groove 212 can be brought closer together, thereby ensuring the overall strength of the optical fiber structure 200 when untorn and improving the ease of tearing the optical fiber structure 200 when torn. In some embodiments, the angle of the tear groove 212 can also be 5°, 10°, or greater than 15°, which is not intended to be the only limitation.

[0041] The present invention also provides an air-blown optical cable array 1, which includes multiple groups of air-blown optical cable assemblies 10 as in any of the above embodiments. The air-blown optical cable assemblies 10 also include a connecting structure 300, and the multiple groups of air-blown optical cable assemblies 10 are detachably connected through the connecting structure 300.

[0042] It can be understood that in the air-blown optical cable array 1 of this embodiment, by providing the air-blown optical cable assembly 10 of any of the above embodiments, the air-blown optical cable assembly 10 of this embodiment provides a guide portion 120 in the outer tube structure 100 to cooperate with the guide groove 211 of the optical fiber structure 200. During the air-blowing conveying process of the optical fiber structure 200, the conveying of the optical fiber structure 200 can be guided to reduce the friction between the optical fiber structure 200 and the inner wall of the accommodating cavity 111, thereby improving the conveying efficiency and smoothness of the optical fiber structure 200. By providing multiple groups of air-blown optical cable assemblies 10, it is convenient to achieve an array combination of air-blown optical cable assemblies 10.

[0043] Specifically, the connection structure 300 includes a connection groove 310 and a connection protrusion 320, which are respectively arranged on the outer wall of the outer tube structure 100, and the two adjacent groups of air-blown optical cable assemblies 10 are plugged in and matched through the connection protrusion 320 and the connection groove 310.

[0044] In this embodiment, two adjacent groups of air-blown optical cable assemblies 10 can achieve quick assembly and disassembly by cooperating with each other through the connection grooves 310 and the connection protrusions 320. Furthermore, the connection grooves 310 and the connection protrusions 320 can be arranged along the length of the air-blown optical cable assemblies 10 to improve the connection strength between the two adjacent groups of air-blown optical cable assemblies 10.

[0045] Furthermore, there are multiple groups of connection structures 300 , and the multiple groups of connection structures 300 are respectively arranged on the outer tube structure 100 .
