Description

Technical Field

[0001] This utility model relates to the field of skeleton-type optical fiber technology, and in particular to a skeleton-type optical fiber cable structure. Background Technology

[0002] As we all know, with the rapid development of optical fiber communication technology and the increasing popularity of fiber to the home, stranded optical cables and central loose tube optical cables are not convenient for splitting optical fibers during home installation, resulting in complicated optical fiber splicing procedures. They are not as easy to use as skeleton-type split optical cables.

[0003] The utility model patent with publication number CN210514733U in the prior art proposes a skeleton-type separated optical fiber cable structure. The reinforcing ribs fixedly installed inside the through holes can improve the overall strength of the optical cable. Under the action of the waterproof layer and the water-blocking layer, the water resistance of the optical cable is effectively improved. Under the action of the reinforcement layer and the buffer layer, the compressive strength is improved. The protrusions facilitate the interlocking of the optical cables during the burial process, which is used to stabilize the optical cable.

[0004] However, it lacks the ability to adjust and install optical cables. Relying solely on the friction of the protruding blocks for burial installation is ineffective, the installation method is relatively simple, and the scope of application is limited, which reduces the practicality of the device. At the same time, its buffering effect on optical cables is also average. The buffer layer alone cannot provide effective buffering and shrinkage space for optical cables. Therefore, we need to upgrade and modify the existing technology to overcome the existing problems and shortcomings. Utility Model Content

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1 As shown in Figure 4, the skeleton-type optical fiber cable structure provided in this embodiment includes a device body 1. The device body 1 includes an outer protective sleeve 2, a central reinforcing rod 3, an optical fiber ribbon 4, and an installation component 5. A skeleton support 8 is provided on the inner side of the outer protective sleeve 2. Multiple sets of optical fiber ribbons 4 are arranged in a ring array and installed in the skeleton support 8. The central reinforcing rod 3 is located in the middle of the skeleton support 8.

[0026] In this embodiment, the installation component 5 is disposed on the outer wall of the outer protective sleeve 2. The installation component 5 includes a fixed sleeve 51 and an adjusting sleeve 54. The adjusting sleeve 54 is fixedly connected to one side of the outer wall of the fixed sleeve 51. The fixed sleeve 51 is sleeved on the outer wall of the outer protective sleeve 2. A side block 52 is provided on one side of the fixed sleeve 51. A fixing bolt 53 is installed in the side block 52. An adjusting rod 55 is movably inserted into the outside of the adjusting sleeve 54. Adjusting holes 56 are correspondingly opened on the adjusting sleeve 54 and the adjusting rod 55. An adjusting bolt 57 is fixedly inserted through the adjusting hole 56. A mounting base 58 is fixed to the outer end of the adjusting rod 55. The fixed sleeve 51 is locked to the outside of the outer protective sleeve 2 by the side block 52 and the fixing bolt 53. The adjusting rod 55 is extended and retracted by the adjusting bolt 57 and the adjusting hole 56, thereby realizing the extension and retraction adjustment of the mounting base 58. This facilitates the connection and installation of the optical cable with external equipment, adapts to more installation environments and usage requirements, prevents the optical cable from shaking, and ensures safety during use.

[0027] In this embodiment, multiple sets of external buffer holes 21 are arranged in a ring array on the inner wall of the outer protective sleeve 2, and multiple sets of internal buffer holes 82 are arranged in a ring array inside the bone groove support 8. Several reinforcing ribs 81 are also provided inside the bone groove support 8. A water-blocking layer 7 is sleeved on the outer side of the optical fiber ribbon 4 and the bone groove support 8. An aluminum-plastic composite tape 6 is provided between the water-blocking layer 7 and the outer protective sleeve 2. The aluminum-plastic composite tape 6 is used to tighten and protect the optical fiber, the water-blocking layer 7 is used to provide external waterproof protection, and the internal buffer holes 82 and external buffer holes 21 are used to provide external compression protection for the optical cable. When the optical cable is compressed, it has the ability and space to contract, which prevents the optical fiber from breaking and being damaged, further improving the safety and practicality of the device.

[0028] The working principle and process of this utility model are as follows: During use, the fixing sleeve 51 can be fitted over the outer protective sleeve 2, and fixed by the side block 52 and fixing bolt 53. The adjusting rod 55 can be extended or retracted by the adjusting bolt 57 and adjusting hole 56 to change the distance between the mounting base 58 and the optical cable. Then, the mounting base 58 can be fixedly connected to external equipment or a wall. This improves the stability of the optical cable during use, preventing it from shaking or loosening. When the optical cable is subjected to external pressure or impact, the outer protective sleeve 2 first protects the optical cable, and then the outer buffer hole 21 and inner buffer hole 82 buffer the pressure or impact force, giving the optical cable a certain amount of contraction space. This prevents the optical cable from directly deforming or breaking under stress, improving the service life and safety of the optical cable.
