Below with reference to the accompanying drawings and describe the invention in detail in conjunction with the embodiments.
A kind of light-duty leading in cable, as shown in Figure 1, its cross section is the figure of eight, comprises the lifting portion 1 on top and the optical cable portion 2 of bottom, is provided with sheath 3 outside described lifting portion 1 and optical cable portion 2, and described sheath 3 is formed and hangs neck 4 between lifting portion 1 and optical cable portion 2; Nylon layer 5 is provided with outside described sheath 3; Nonmetal round bar 6 is provided with inside the sheath 3 in described lifting portion 1; Pine cover unit 11 is provided with inside the sheath 3 in described optical cable portion 2; Described pine cover unit comprises the optical fiber 8 for some different colours in protection internal optical fiber and the protection tube 7 that longitudinally extrudes and protection tube 7, is filled with dry type material water-proof material 9 between each optical fiber 8 and between optical fiber 8 and protection tube 7; Nonmetal protection fibrage 10 is provided with between described protection tube 7 and described sheath 3.The thickness of sheath 3 being wrapped in nonmetal round bar 6 and being wrapped in pine cover unit 11 outside is generally 0.6mm ~ 1.5mm and it is to be noted, color on optical fiber is all through ultraviolet light polymerization, colour-fast, do not move, and be arranged with a definite sequence between different colours optical fiber.
It should be noted that; protection tube is generally circle; its external diameter is 1.5mm ~ 3.0mm; a fixed gap is had between each optical fiber and protection tube; namely optical fiber is freely movable in protection tube, then, invades to prevent moisture; while extruding protection tube, in the space of fiber unit, longitudinally place some dry type material water-proof materials as water-blocking component.This dry type material water-proof material can be Powdered, also can be linear fiber, and they are meeting moisture expantion when running into moisture, plays and stop water longitudinal seepage effect in protection tube.
With during dish cable, optical cable portion 2 is separated with lifting portion 1 for ease of fiber stripping easily, is hanging the monosymmetric groove 12 being provided with section triangle in the middle part of neck 4.Meanwhile, pine is overlapped unit 11 and be arranged in parallel with nonmetal round bar 6, conveniently have an effect, optical cable portion 2 is separated with lifting portion 1 and is more prone to.
Wherein, described nonmetal round bar 6 is fiberglass pole, and its diameter preferably adopts 2.5mm-4.0mm, to ensure mechanical stretching performance.
Wherein, nonmetal protection fibrage 10 can be the strand fiberglass of bonding one.Or nonmetal protection fibrage 10 also can for being evenly coated on some glass fibre of described protection tube 7 outside.The fibrolaminar thickness of nonmetal protection answers >=0.3mm.To play lateral pressure resistant effect.
Wherein, optical fiber 8 quantity in described protection tube 7 is 2 ~ 12.The market that the usage quantity adapting to current 12 cores and following optical cable constantly rises.
Wherein, the longitudinal extrusion forming of described nylon layer 5, its thickness is 0.3 ~ 0.5mm.Because nylon has, hardness is high, rub resistance, therefore in the outside of sheath, longitudinally extrudes one deck nylon layer 5, has the feature of rub resistance, life-span length, can also bite by good anti-mouse simultaneously.
The invention adopts dry type material water-proof material in the pine cover unit 11 of cable portion 2, easy to clean during construction.Adopt nonmetallic reinforcement material, protection tube 7 is protection tube simultaneously, and overall weight is light, carries, lays easily.Owing to have employed nylon outer jacket, avoid ointment material in the past and easily suffer the destructions such as worm mouse, serve protection against rodents effect.In addition, devise groove 12 hanging on neck 4, being separated of fiber unit and nonmetal round bar after being convenient to optical cable to optical cross box, facilitates fiber stripping and dish cable.
The foregoing is only the preferred embodiment of the invention; not in order to limit the invention; within all spirit in the invention and principle, any amendment done, equivalent replacement, improvement etc., within the protection domain that all should be included in the invention.
