Description

Technical Field

[0001] The utility model relates to the technical field of reinforcement cores, in particular to a novel tensile strength reinforcement core. Background Art

[0002] The existing reinforcing core provides protection for the internal optical fiber through a sleeve and reinforcing materials. However, when it is used, the sleeve is a single-layer design, and the reinforcing core of the single-layer design has only one layer of reinforcing material, and its tensile performance is relatively poor. For example, a Chinese patent discloses a "reinforcing core for optical cable", and its application number is "202222616630.4". In this device, the reinforcing core of the optical cable is wound with a double-strand branch inner core, which strengthens the supporting strength of the reinforcing core of the optical cable. At the same time, beryllium copper wire with excellent elasticity is wound on the outside of the reinforcing core of the optical cable to increase the bending strength. The foldability and flexibility make the optical cable and the reinforcement core of the optical cable resistant to bending. The water-blocking tape on the outside of the reinforcement core of the optical cable is provided with a highly absorbent fiber layer and a water-absorbent fiber rope on the outside of the water-blocking tape to absorb the moisture on the outside of the reinforcement core, so that the surrounding area of ​​the reinforcement core is kept dry, thereby preventing the reinforcement core from rusting due to contact with moisture. However, when it is used, this device only has a single reinforcement material, and its compressive resistance is poor. It cannot effectively disperse or absorb external pressure. When subjected to pressure, it is easily compressed or deformed, which leads to a decrease in the mechanical properties of the optical fiber. Utility Model Content

The reinforcement core structure composed of an outer protective layer of polyethylene material, a reinforcement layer 1 of glass fiber material, a reinforcement layer 2 of carbon fiber material, and an inner liner layer of polyimide material can provide the high strength, light weight, corrosion resistance and good temperature performance required by the optical cable. The polyethylene outer protective layer provides mechanical protection and tensile strength, the glass fiber and carbon fiber effectively protect the optical fiber from external pressure and impact, and the polyimide inner liner layer has chemical corrosion resistance, thereby extending the service life of the optical cable. By combining the two halves of the reinforcement core structure into one through a card slot and a card block, the installation of the internal optical fiber becomes simpler and more convenient.
