Detailed Description
It should be noted that the embodiments and features of the embodiments of the present invention may be combined with each other without conflict.
The following detailed description of the embodiments of the invention is provided.
A high-strength multi-core easily-identified novel cable comprises an optical cable unit 1 and an outer reinforcing unit 2 on one side of the optical cable unit 1, as shown in figure 1; the outer sheath 3 of the optical cable unit coated on the outer side of the optical cable unit is connected with the outer sheath 4 of the outer reinforcing unit coated on the outer side of the outer reinforcing unit through a connecting neck 5; specifically, the connecting neck can be integrally formed with the outer sheaths of the optical cable unit parts and the outer reinforcing unit parts on the two sides, and the connecting neck is made of rubber;
an outer reinforcing piece 6 is arranged inside the outer sheath of the outer reinforcing unit part;
the optical fiber component 11 is arranged in the optical cable unit part outer sheath, the optical cable unit part outer sheath comprises two sheath bodies 7 which are arranged side by side, a V-shaped groove 8 pointing to the optical fiber component is arranged on the outer side of the joint of the two sheath bodies, and an inner reinforcing piece 9 is arranged in each sheath body;
the outer side of the sheath body, which is different from the side provided with the outer reinforcing unit, is provided with a color bar 10.
The invention has the advantages of meeting the requirements of all indexes, simple use and operation, good structural stability, excellent tensile and compressive capacities, high reliability of the product in the use process, no limitation and wide application range, and can be used in any indoor and outdoor scenes.
The outer reinforcement is made of phosphated steel wire. Typically, it is 1.6mm in diameter, ensuring a tensile resistance of 1200N. The tensile capacity of the cable is greatly improved.
The color strips are arranged on one side of the corresponding sheath body different from the outer reinforcing unit. The width of the white color strip is equal to the outer section of the sheath body, and the thickness of the white color strip is 0.2 mm. Can paste the setting, also can adopt other modes, white colour bar can not bring too much influence to optical cable itself size, and the setting of white colour bar can effectively improve the identifiability of optical cable, especially to the today that science and technology rapidly developed, has arranged a large amount of cables in the pipeline usually, does not have clear and definite identification information between each cable, very easily arouses to obscure, is difficult to seek the discernment fast.
Just because this optical cable has optimized structural design, consequently, 6 core structures can be accomplished to the biggest to its inside fiber core number that can set up, promptly, can contain 6 G.657A2 optic fibres, for prior art, greatly increased the fiber core number, the range of application is wider, and the functionality is abundanter, provides reliable guarantee for FTTH and 5G development and construction.
