A protective sheath for hot-melt splicing of butterfly-shaped leather cable

Abstract

The invention discloses a protective sheath for hot-melt splicing of butterfly-shaped leather-wire optical cables, which belongs to the field of butterfly-shaped leather-wire optical cables. It is a protective sheath for hot-melt splicing of butterfly-shaped leather optical cables. The optical fiber hot-melt machine is operated, and the original rubber sheath is modified into a continuous protective sleeve. During the low-temperature treatment stage, the connecting fiber that is involved in the mesh sleeve and the attached sticker is easy to break at the prefabricated slot, and the mesh Under the action of low temperature treatment, the remaining part of the connecting fiber of the sleeve connection forms a three-dimensional helical structure, and the multiple connecting fibers are entangled with each other to form a three-dimensional space to form the skeleton of the coating adhesive layer. On the one hand, the heat can be evenly transferred to the coating adhesive. In the inner layer, the coating rubber layer can be softened evenly. On the other hand, it can also increase the strength of the softened coating rubber layer, so that it is not easy to be excessively deformed during the cooling and hardening molding process, and can realize the increase of the butterfly for hot-melt splicing. Protective effect of shaped leather cable.

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...

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
