Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, in an embodiment of the present invention, a high-strength optical fiber patch cord includes an optical fiber body 1, and both ends of the optical fiber body 1 are connected to optical fiber movable connectors 2. The optical fiber line body 1 includes sinle silk 11, and the outside of sinle silk 11 outside cladding has sheath 12 and fire-retardant layer in proper order. The flame retardant layer is including the cladding at the first flame retardant layer 13 in the sheath 12 outside, and the cladding in the outside of first flame retardant layer 13 has metal to weave protective layer 14, and the cladding in the outside of protective layer 14 has the flame retardant layer 15 of second. Preferably, the first flame retardant layer 13 and the second flame retardant layer 15 are made of flame retardant polyolefin material.

The second flame-retardant layer 15 cladding is in the outside that protective layer 14 was woven to the metal, can slow down the oxidation rate that protective layer 14 was woven to the metal under normal use, and the second flame-retardant layer 15 makes this optic fibre jumper nonflammable. When the second flame-retardant layer 15 is damaged by an external force, the metal woven protective layer 14 can effectively protect the first flame-retardant layer 13, so that the first flame-retardant layer 13 is not easy to damage. Under the damaged condition of fire-retardant layer 15 of second, better flame retardant efficiency can be guaranteed to this optic fibre wire jumper.

The metal woven protective layers with different sizes can be arranged according to the use scene: when the metal braided protective layer is used at home, the metal braided protective layer can be arranged to be thinner, so that the metal braided protective layer is easier to bend and wire; when the metal braided protective layer is used outdoors, the metal braided protective layer can be arranged to be a little thicker, so that the small animals can be prevented from being bitten and broken; when the metal braided protective layer is used in a workshop, the metal braided protective layer can be densely arranged, namely, the holes are smaller, and sharp objects are prevented from piercing the wire core.

In the embodiment of the utility model, the outer side of the sheath 12 is provided with a shock absorption layer 16 for absorbing shock when the optical fiber patch cord is stressed. This optic fibre wire jumper is possessing the metal and weaves under the condition of protective layer 14 and buffer layer 16, when receiving the foreign object striking, the metal is woven protective layer 14 and can be avoided the foreign object directly to pierce through sinle silk 11, and buffer layer 16 can absorb the produced vibrations of striking, avoids sinle silk 11 because vibrations are too big and fracture or fracture, and bulk strength is higher.

Further, the shock absorbing layer 16 is formed by annularly connecting a plurality of V-shaped supporting blocks. The shock-absorbing layer 16 forms a plurality of air chambers between the sheath and the first flame retardant layer 13 for isolating the transfer of heat.

Further, the outer side of the shock-absorbing layer 16 is provided with a heat-insulating material, so that the heat-insulating protection of the wire core 11 is further enhanced. Preferably, the insulating material is fiberglass. The glass fiber has the advantages of good insulation, strong heat resistance, good corrosion resistance and high mechanical strength.
