Detailed Description
The present invention will be described in further detail with reference to the accompanying fig. 1-2.
The embodiment of the utility model discloses strenghthened type platykurtic optical fiber cable, as shown in fig. 1-2, including three fibre cores 1, three fibre cores 1 are along the width direction interval arrangement of optical cable, and the parcel has interior sleeve pipe 2 on the fibre core 1, and interior sleeve pipe 2 is the pe material, and pe is also called polyethylene, is a thermoplastic resin that ethylene made through polymerization. The chemical stability is good, most of acid and alkali erosion can be resisted, the fiber core is insoluble in common solvents at normal temperature, the water absorption is small, the electrical insulation is excellent, and the fiber core 1 can be well protected. The inner sleeve 2 is externally provided with the fiber paste layer 3, the fiber paste layer 3 is fiber paste, and the fiber paste is a soft, non-sticky, water-blocking, non-toxic, harmless and crystal clear paste compound, and has wide refraction and optical fiber, zero oil separation rate, good oxidation resistance and long-term stability. Three fibre cores 1 all are located fine cream layer 3, and fine cream layer 3 has certain buffer performance, can take place deformation absorption energy when the optical cable receives pressure and play the guard action to fibre core 1. The outer sheath 4 is arranged on the fiber paste layer 3, the outer sheath 4 is made of nylon, the nylon is also called polyamide, the fiber paste layer has the advantages of being light in weight, good in crease resistance, good in air permeability, good in durability, dyeing property, heat setting and the like, and the outer sheath 4 can protect the fiber paste layer 3.
Referring to fig. 1 and 2, in addition, be provided with two strengthening bands 5 in the fine cream layer 3, strengthening band 5 is made by iron or aluminium, strengthening band 5 sets up along the length direction of fibre core 1, one side of strengthening band 5 is the setting of buckling, thereby make strengthening band 5 be the setting of J shape, the partial lateral surface of buckling of strengthening band 5 and the straight partial surperficial looks butt towards fibre core 1 of another strengthening band 5, two strengthening bands 5 are around each other together, three fibre cores 1 all are located two strengthening bands 5 in around the space that forms, when the optical cable received external pressure, two strengthening bands 5 can improve the compressive strength of optical cable, make the optical cable difficult by the crushing, thereby play the guard action to fibre core 1.
