Problems solved by technology
[0004] Compared with the cold splicing technology, the biggest disadvantage of the hot-melt technology is that the optical fiber hot-melt machine is expensive and the cost is high, but the laying and maintenance of the optical fiber is the work of the communication company, and the hot-melt machine does not need to be purchased by the maintenance personnel, so The impact is relatively small. In the existing butterfly cable extension technology, the protection for the connection point is relatively small. In the process of use, once the structures such as the protective rubber sheath and the anti-leakage tape used for protection are aging If it falls off, it will easily affect the connection point, which will affect the quality of communication and user experience, and cause communication interruption and affect the normal life and work of users

Embodiment 1
[0042] see figure 2 , Figure 4 , Figure 5 , Figure 9 and Figure 10 , a protective sheath for hot-melt splicing of a butterfly-shaped leather cable, including a continuous protective sheath 4 that is sleeved on the butterfly-shaped leather cable. The butterfly-shaped cable includes an optical fiber main body 1, two reinforcements 2 and PVC Sheath 3, the cross section of PVC sheath 3 is "8" shape, fiber main body 1 is located on the center of "8" character, strengthening member 2 is symmetrically distributed on both sides of fiber main body 1, PVC sheath 3 connects optical fiber main body 1 and two A reinforcing member 2 covers it, and the extension protective sleeve 4 is set on the outside of the optical fiber main body 1. The extension protection sleeve 4 includes a mesh sleeve 401, and the outside of the mesh sleeve 401 is fixedly connected with a coating rubber layer 404. The end of the covering rubber layer 404 away from the mesh sleeve 401 is fixedly connected wit...

Abstract
The invention discloses a protection sheath for hot melting splicing of a butterfly-shaped rubber-insulated wire optical cable, and belongs to the field of butterfly-shaped rubber-insulated wire optical cables. According to the scheme, an existing optical fiber hot melting machine is used for operation, an original rubber sheath is modified into a splicing protection sheath, and in the low-temperature processing stage, the connecting fibers pulled by a net-shaped sleeve and an attachment paster are prone to being broken at the prefabricated notch, the connecting fiber residues connected with the net-shaped sleeve form a three-dimensional spiral structure under the low-temperature treatment effect, the multiple connecting fibers are mutually entangled, a three-dimensional space is formed, and a framework coated with an adhesive layer is formed. According to the invention, heat can be uniformly transmitted into the coating rubber layer, so that the coating rubber layer is uniformly softened, and the strength of the softened coating rubber layer can be increased, so that the coating rubber layer is not easy to excessively deform in the cooling, hardening and forming process, and the protection effect on the hot-melting continuous butterfly-shaped rubber-insulated wire optical cable can be improved.
Description
technical field [0001] The invention relates to the field of butterfly sheath optical cables, and more specifically relates to a protective sheath for hot-melt splicing of butterfly sheath optical cables. Background technique [0002] Butterfly leather cable is commonly known as indoor suspension wiring cable. With the domestic optical fiber access market showing a good momentum of development, optical fiber access has become a hot spot in the field of optical communication. In the fiber optic access project, the indoor wiring close to the user is the most complicated link. The bending performance and tensile performance of conventional indoor optical cables can no longer meet the needs of fiber-to-the-home indoor wiring. The core structure can also be made into a four-core structure. The cross-section is in the shape of an 8. The strengthening member is located in the center of the two circles. It can be made of metal or non-metal structure. The optical fiber is located in...
