Description

Technical Field

[0001] The utility model relates to the technical field of optical cables, in particular to a butterfly-shaped optical cable with stable use. Background Art

[0002] Optical cable is a communication cable assembly that uses one or more optical fibers placed in a sheath as a transmission medium and can be used alone or in groups. It is mainly composed of optical fiber, plastic protective sheath and plastic sheath. The optical fiber is made into a cable core through a certain process and covered with a sheath. Some are also covered with an outer sheath to achieve optical signal transmission;

[0003] The butterfly-shaped optical cable in the optical cable has a compact structure and can accommodate more optical fibers in a limited space, reducing the space occupied by the optical cable. However, although the existing butterfly-shaped optical cable has added a reinforcing core, although the structural strength of the optical cable is enhanced, the diameter of the reinforcing core is small, and when the optical cable is bent under force, the reinforcing core will also bend. After the reinforcing core is bent, it cannot achieve self-deformation and reset due to material reasons, resulting in the optical cable being partially bent multiple times, causing the wire core in the optical cable to break. In addition, when laying multiple optical cables, fixed structures such as cable ties are used to tie and fix the multiple optical cables. Although multiple optical cables can be laid in the same direction, it brings inconvenience to the subsequent disassembly and replacement of a single optical cable. Utility Model Content

With the help of the reset bar 5 and its toughness, on the one hand, it can provide the entire optical cable with anti-bending ability, and on the other hand, it can make the bent optical cable rebound and reset. The inner core layer 10 is made of rubber. The first reinforcement layer 6 and the second reinforcement layer 9 are both made of aramid fiber. The wear resistance of the optical cable can be improved by setting the first reinforcement layer 6 and the second reinforcement layer 9. The protective layer 8 is made of nylon. The mechanical properties of nylon can be used to resist external impact and extrusion.
