Embodiment 1

[0022] Example 1: A tensile torsion fiber optic cable

[0023] See figure 1 , Including a central reinforcement core 1, a tensile and torsion member 2 is sheathed outside the central reinforcement core 1, and the tensile and torsion member 2 is a sleeve structure that is arranged concentrically with the central reinforcement core 1 , And the sleeve structure is provided with a gap 20 along the length direction. The gap 20 is opened from the outer surface of the sleeve structure to the inner surface of the sleeve structure, and the outer surface of the sleeve structure is evenly spaced along the circumferential direction. There are two grooves 21, each groove 21 is arranged from the inside to the outside, and each groove 21 is provided with an inner insulating sheath 30, and each inner insulating sheath 30 is provided with an optical fiber 3, therefore, There are eight inner insulating sheaths 30 with optical fibers 3, and the centers of the circles where the eight optical fibers ...

Embodiment 2

[0028] Embodiment 2: A tensile and torsion resistant fiber optic cable

[0029] See attached figure 2 , The rest is the same as the first embodiment, the difference is that the shape of the tensile and torsion component 2 is different, most of which are filled in the gap to play a stable role.

Abstract

The invention relates to a tensile and torsion optical fiber cable, which includes a central strengthening core; a tensile and torsion component is sheathed outside the central strengthening core, and the tensile and torsion component is a sleeve structure, and the sleeve structure is concentric with the central strengthening core Arranged, and the sleeve structure has a gap along the length direction, the gap is opened from the outer surface of the sleeve structure to the inner surface of the sleeve structure, and a number of grooves are arranged at intervals along the circumferential direction on the outer surface of the sleeve structure, each Each groove is arranged from the inside to the outside, and an inner insulating sheath is arranged in each groove, and an optical fiber is arranged in each inner insulating sheath; When the optical fiber is squeezed, the gap in the tensile torsion part is closed due to deformation. The invention has good reliability and can effectively improve the tensile and torsion resistance effect of the entire optical fiber cable.

Description

Technical field [0001] The invention belongs to the field of optical fibers, and specifically relates to a tensile and torsion resistant optical fiber cable. Background technique [0002] As we all know, fiber optic cables are usually rope-like cables formed by twisting several or several groups of wires. Each group of wires is insulated from each other and often arranged around the center. The entire outside is covered with a highly insulating coating. Cables are erected in the air or installed underground or underwater for telecommunications or power transmission. [0003] Optical fiber cables have a wide range of uses, and their performance requirements vary greatly in different applications. Insulating materials of most cables must have high insulation resistance, low dielectric loss with voltage strength, and good physical and mechanical properties, such as tensile and torsion resistance. [0004] At present, in order to improve the utilization rate of optical fiber cables, mu...
