Abstract

An ultraviolet radiation solidified silicone coating and aiming optical fiber widely used for transmitting the aiming signal on land, in air and on water is provided with a light guide fiber as an inner core, solidified aramid fiber yarn or aramid fiber filament wounded outside of the optical fiber with the fiber interval saturated with the silicone as a protective layer, and a layer of silicon outer protective layer coated outside of the aramid fiber yarn or the aramid fiber filament enforcement layer. The silicone at the fiber interval of the aramid fiber yarn or aramid fiber filament and the silicone at the outer protective layer coated outside the enforcement layer are ultraviolet fast solidifying silicone. The ultraviolet radiation solidified silicone coating and aiming optical fiber has the advantages of even and compact optical fiber enforcement layer, high tensile strength, resistance to repeated bending and breakage, strong water-proof, high rate of finished products, stable and reliable product quality and long life.

Description

Ultraviolet curing silicone-coated Guidance optical cable

Affiliated technical field

It is ultraviolet curing silicone-coated Guidance optical cable that the utility model relates to a kind of optical communication optical cable.

Background technology

Existing optical communication Guidance optical cable; be to extrude the skim plastic protective layer to form outside optical fiber, though the extrusion process cost is lower, its weak point is that this kind cable configuration is higher to extrusion molding machinery equipment requirements; extrusion plastic protective seam intensity is relatively poor; easily layering easily makes the local exposed or outer jacket generation pore of optical cable when extrusion molding is inhomogeneous, the finished product rate is low; the not anti-bending of product; protective seam easily breaks, and serviceable life is short, and reliability is relatively poor.

Summary of the invention

Higher to extrusion molding machinery equipment requirements in order to overcome existing Guidance optical cable extrusion plastic protective seam, plastic sheath intensity is low, easily breaks; easily produce pore and crack; make optical cable local exposed, the finished product rate is low, poor water resistance; quality can not get deficiencies such as assurance; the utility model provides a kind of ultraviolet curing silicone-coated Guidance optical cable, makes this optical cable intensity height, the even strong difficult drop-off of coat; guarantee product quality, yield rate improves.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of ultraviolet curing silicone-coated Guidance optical cable, be to form at light transmitting fiber outsourcing aramid fiber yarn and silicon-coating resin, it is characterized in that with optical fiber being inner core, wrapped aramid fiber yarn or long filament enhancement Layer outside fiber cores, outermost covers one deck silicones outer jacket, soaking into silicones in the aramid fiber yarn of above-mentioned described aramid fiber yarn enhancement Layer or the filament fiber gap is also solidified, aramid fiber yarn enhancement Layer covers one deck silicones outer jacket outward again, and above-mentioned described silicones is ultraviolet ray solidification of silicon resin fast.

The beneficial effects of the utility model are and have extrusion molding Guidance optical cable ratio now; the aramid fiber yarn enhancement Layer that silicones is soaked in the optical fiber outsourcing covers one deck silicones outer jacket outward again becomes two protective seams; the liquid silicone resin flowability of uncured; perviousness and attaching property are fabulous; after ultraviolet ray is solidified fast; make enhancement Layer and outer jacket even compact; no holiday and exposed phenomenon; add the aramid fiber reinforcement, the tensile strength height is stood bending repeatedly; be difficult for breaking; water-tolerant, reliable product quality, yield rate significantly improves; long service life, the utility model can be widely used in land; the optical communication optical cable of guidance signal is transmitted in aerial and conduct under water.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the utility model xsect enlarged drawing.

In Fig. 1: 1. light transmitting fiber, 2. soak into the aramid fiber enhancement Layer of silicones, 3. the silicones outer jacket.

Embodiment

In Fig. 1, a kind of ultraviolet curing silicone-coated Guidance optical cable is at optical fiber outsourcing aramid fiber yarn or long filament, covering the silicones outer jacket outward forms, it is characterized in that with light transmitting fiber (1) be inner core, wrapped aramid fiber yarn or long filament enhancement Layer (2) outside optical fiber (1) inner core, outermost layer covers one deck silicones outer jacket (3) again, soaking into silicones in above-mentioned described aramid fiber yarn or the long filament enhancement Layer in aramid fiber yarn or the filament fiber is also solidified, be covered with one deck silicones outer jacket (3) again outside aramid fiber yarn or long filament enhancement Layer (2), the silicones in the above-mentioned described outer jacket that is impregnated into the silicones in aramid fiber yarn or the filament fiber and covers outward is ultraviolet ray solidification of silicon resin fast.

Claims
