Mutually-embedded rubber and plastic double-sheath optical cable and manufacturing method thereof

Abstract

The invention relates to a mutually-embedded rubber and plastic double-sheath optical cable and a manufacturing method, the optical cable comprises a cable core, the periphery of the cable core is sequentially sleeved with a protective layer, a sheath and an outer sheath from inside to outside, an embedded structure is arranged between the sheath and the outer sheath, the embedded structure comprises concave structures and convex structures, the concave structures are densely distributed on the outer side of the sheath, and the convex structures are arranged on the outer side of the sheath. The inner side of the outer sheath is densely distributed convex structures, and the concave structures and the convex structures are mutually embedded; the sheath and the outer sheath are made of rubber and plastic materials which are different in variety. According to the invention, through reasonable combination of different rubber and plastic materials of the two layers of sheaths of the mutually-embedded rubber and plastic double-sheath optical cable, the phenomenon that the sheaths are damaged due to insufficient binding force between the two layers of sheaths made of different materials is overcome, and the advantages of different materials can be given full play, so that the specific function and performance requirements of the optical cable are met; the optical cable with a special protection function, which has more functions and wider application occasions, is developed.

Description

technical field [0001] The invention belongs to the technical field of optical cables and cables, and relates to an optical cable with inter-embedded rubber and plastic double sheaths and a manufacturing method. Background technique [0002] With the power and communication, more and more multi-functional optical cables and cables are used, and the functional and performance requirements of the sheath are also getting higher and higher. The use of a single material for the sheath is far from meeting the performance requirements, and two layers of different materials are required. The combination of the sheath to meet its function and performance and use requirements. Plastics and thermoplastic elastomers are the most commonly used sheath materials for optical cables and cables, and their advantages and disadvantages are often prominent. For example, nylon, with high mechanical strength and low surface friction, has the function of preventing rodents such as mice and termite...
