Specific implementation mode
Net self-support cable is accessed to a kind of multicore of the utility model with reference to Figure of description, is said in detailed below
It is bright.
Embodiment one
As shown in Figure 1, the utility model a kind of multicore access net self-support cable, structure include messenger section and
Cable portion, the messenger section are connected with cable portion by suspender belt;The cable portion is by tight tube fiber 2, reinforcer
4, fire-retardant oversheath 1, insulation pack band 5 and wrinkle steel band 6 are constituted, and the messenger section is made of steel strand wires 7 and fire retardant jacket.
Solve the problems, such as in loose sleeve optical cable that simple optical fiber can not directly register one's residence connecting using tight tube fiber.
Longitudinal wrap is heat-insulated again outside 4 screw type twisted synthesizing cable of center reinforcemen, more tight tube fibers for more tight tube fibers 2
Two tear ropes, 5 outside longitudinal wrap wrinkle steel band 6 of the insulation pack band are placed in parallel after band 5, wrinkle steel band outside is equipped with fire-retardant
Oversheath.
Embodiment two
As shown in Fig. 2, tight tube fiber 2 in cable core if there is certain surplus, is not easy stress, the composition of round cable core,
Under the premise of ensureing use intensity, the circle for forming consolidation at least needs five tight tube fibers, when the fixed light used of registering one's residence
When fine radical is less than five, needs to fill a vacancy by gasket for packing 3, minimum five rhizosphere of cable core is made to be wound on around reinforcer.It solves
Optical fiber is without surplus in single tight tube fiber, the problem of easily making optic fibre force.
More tight tube fibers 2 and gasket for packing 3 are outside 4 screw type twisted synthesizing cable of center reinforcemen, more tight tube fibers
It is placed in parallel two tear ropes after longitudinal wrap insulation pack band 5 again, longitudinal wrap wrinkle steel band 6 outside the insulation pack band, outside wrinkle steel band 6
Portion is equipped with fire-retardant oversheath 1.
Cable core longitudinal wrap wrinkle steel band, make optical cable increase damp-proof layer while, efficiently solve optical cable lateral pressure resistant and ant proof,
The problem of insect prevention, protection against rodents.
The tight tube fiber is in the coated low-smoke halogen-free flame-retardant sheath of outer fiber.It can play the role of anti-flaming thermal-insulation.
Tight tube fiber external diametrical extent is 0.5-1.0mm.
As shown in figure 3, the self-support cable of the utility model includes the following steps:
The first step:The preparation of light unit
It is drawn and is molded by extruding machine, low-smoke halogen-free flame-retardant sheath material is coated on optical fiber, form tight tube fiber;
Second step:Prepare before restrictive coating
