Description

Technical Field

[0001] The present application relates to the field of optical cable components, and in particular to an optical cable bundling tube. Background Art

[0002] The optical cable bundling tube is a bundling tube used in optical cable laying projects, which includes an outer tube and multiple micro tubes inserted into the outer tube, and the micro tubes are used to accommodate optical cables.

[0003] During the installation and use of optical cable bundle tubes, since there is no relative limit between the micro-tubes and the outer tube, the micro-tubes are prone to shaking and relative collision with other micro-tubes or outer tubes, causing the micro-tubes to twist and deform. The twisted and deformed micro-tubes are prone to damage the optical cable, which seriously affects the transmission quality and efficiency of light in the optical cable. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the present application provides an optical cable bundling tube capable of preventing micro-tubes from shaking.

[0005] The present application provides an optical cable bundling tube adopting the following technical solution:

[0006] An optical cable bundling tube comprises an outer tube and a plurality of micro tubes passing through the outer tube. The inner wall of the outer tube is provided with a plurality of first contact parts for the micro tubes to abut against at intervals around the inner wall of the outer tube. The outer wall of the micro tube is relatively embedded with the first contact parts.

[0007] By adopting the above technical solution, the microtube can be relatively limited with the outer tube through the first contact portion, which effectively prevents the microtube from shaking, thereby avoiding relative collision between the microtube and other microtubes or the outer tube, preventing damage to the optical cable due to twisting and deformation of the microtube, and improving the transmission quality and efficiency of light in the optical cable.

[0008] In a specific possible implementation scheme, the first contact portion is provided with a plurality of first limiting teeth arranged along the circumferential direction of the outer tube, the microtube is provided with a plurality of second limiting teeth around its own circumference, the outer wall of the microtube has a second contact portion that conflicts with the first contact portion, and the plurality of second limiting teeth located on the second contact portion are staggered and engaged with the plurality of first limiting teeth.

[0009] By adopting the above technical solution, the relative limiting effect between the microtube and the outer tube is effectively improved.

[0010] In a specific possible implementation manner, an end surface of the first limiting tooth facing the microtube is a curved surface.

[0011] By adopting the above technical solution, it is possible to prevent the end of the first limiting tooth from being too sharp and causing damage to the microtube.

[0012] In a specific possible implementation manner, two adjacent microtubes respectively have third contact portions that interfere with each other, and the plurality of second limiting teeth located on the two third contact portions are staggered and interlocked.

[0013] By adopting the above technical solution, two adjacent microtubes can achieve relative limiting through their respective third contact parts, avoiding relative shaking or collision between the two adjacent microtubes, thereby preventing damage to the optical cable due to twisting and deformation of the microtubes, and improving the transmission quality and efficiency of light in the optical cable.

[0014] In a specific possible implementation manner, the inner wall of the outer tube is provided with a plurality of partitions at intervals around its own circumference, and each of the partitions is respectively provided between two adjacent first contact portions.

[0015] By adopting the above technical scheme, multiple partitions can play the role of separation and guidance, which can not only improve the installation quality and efficiency of the microtubes in the outer tube, but also prevent twisting and entanglement between multiple microtubes, thereby preventing damage to the optical cable due to twisting and entanglement of the microtubes, thereby improving the transmission quality and efficiency of light in the optical cable.

[0016] In a specific possible implementation manner, the end surface of the partition is a curved surface.

[0017] By adopting the above technical solution, it is possible to prevent the end of the partition from being too sharp and causing damage to the microtube.

[0018] In a specific possible implementation manner, the outer tube includes a tube body and a metal protective layer attached to the inner wall of the tube body.

[0019] By adopting the above technical solution, the structural strength of the outer tube is effectively improved, so that the outer tube is not easily deformed under the action of external force and causes squeezing of the microtubes, thereby preventing damage to the optical cable due to squeezing of the microtubes, and improving the transmission quality and transmission efficiency of light in the optical cable.

[0020] In a specific possible implementation manner, the outer tube further comprises a buffer layer attached to the inside of the metal protective layer, and the plurality of first contact portions are respectively arranged on the inner wall of the buffer layer.

[0021] By adopting the above technical solution, the buffer layer can serve as a buffer between the micro-tubes and the metal protective layer, thereby preventing the micro-tubes from directly colliding with the metal protective layer and causing unnecessary wear.

[0022] In a specific possible implementation manner, the outer tube further comprises an anti-permeation layer disposed between the tube body and the metal protective layer.

[0023] By adopting the above technical solution, the anti-permeation layer can prevent ultraviolet rays from penetrating the outer tube, thereby avoiding damage to the optical cable under the irradiation of ultraviolet rays.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] The microtube can achieve relative limitation with the outer tube through the first contact portion, effectively preventing the microtube from shaking, thereby avoiding relative collision between the microtube and other microtubes or the outer tube, preventing damage to the optical cable due to twisting and deformation of the microtube, and improving the transmission quality and efficiency of light in the optical cable.

[0029] The present application is further described in detail below in conjunction with the accompanying drawings.

[0030] See also Figure 1 As shown, an optical cable bundle tube is shown, including an outer tube 1 and seven micro tubes 2 passing through the outer tube 1, wherein six of the seven micro tubes 2 are arranged around the circumference of the outer tube 1 and in conflict with the inner wall of the outer tube 1, and one of the seven micro tubes 2 is located between the six micro tubes 2.

[0031] Six first contact portions 3 for the six micro-tubes 2 to abut against are arranged at intervals on the inner wall of the outer tube 1 in the circumferential direction thereof, and the outer walls of the micro-tubes 2 are relatively engaged with the first contact portions 3 .

[0032] In this way, the microtube 2 can achieve relative limitation with the outer tube 1 through the first contact portion 3, effectively preventing the microtube 2 from shaking, thereby avoiding relative collision between the microtube 2 and other microtubes 2 or the outer tube 1, preventing damage to the optical cable due to twisting and deformation of the microtube 2, and improving the transmission quality and efficiency of light in the optical cable.

[0033] In this embodiment, the first contact portion 3 is provided with a plurality of first limit teeth 4 arranged along the circumferential direction of the outer tube 1, and the first limit teeth 4 are integrally formed with the first contact portion 3. The microtube 2 is provided with a plurality of second limit teeth 5 around its own circumference, and the second limit teeth 5 are integrally formed with the microtube 2. The outer wall of the microtube 2 has a second contact portion 6 that contacts the first contact portion 3, and the plurality of second limit teeth 5 located on the second contact portion 6 are staggered and interlocked with the plurality of first limit teeth 4.

[0034] In this embodiment, two adjacent microtubes 2 respectively have third contact portions 7 that conflict with each other, and a plurality of second limiting teeth 5 located on the two third contact portions 7 are staggered and interlocked. The two adjacent microtubes 2 can achieve relative limiting through their respective third contact portions 7, thereby preventing relative shaking or collision between the two adjacent microtubes 2, thereby preventing the optical cable from being damaged due to the twisting and deformation of the microtubes 2, and improving the transmission quality and efficiency of light in the optical cable.

[0035] The end surface of the second limiting tooth 5 is also an arc surface. The end surface of the second limiting tooth 5 is designed as an arc surface, which will not cause damage to the outer tube 1 and other micro-tubes 2.

[0036] In this embodiment, the inner wall of the outer tube 1 is provided with six partitions 8 at intervals around its own circumference, and each partition 8 is respectively provided between two adjacent first contact portions 3. Among them, the end face of the partition 8 is an arc surface. The six partitions 8 can play the role of separation and guidance, which can not only improve the installation quality and efficiency of the microtube 2 in the outer tube 1, but also prevent the twisting and entanglement between multiple microtubes 2, thereby preventing the damage to the optical cable caused by the twisting and entanglement of the microtubes 2, and improving the transmission quality and efficiency of the light in the optical cable; at the same time, the end face of the partition 8 is designed as an arc surface, which can prevent the end of the partition 8 from being too sharp and causing damage to the microtube 2.
