Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art
The utility model may be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.
Shown in referring to Fig.1, an embodiment of the light-duty anti-unfirmly closing optical cable of the utility model, including center beam tube 3, it is described in
Heart beam tube 3 is the Loose tube that polybutylene terephthalate (PBT) or modified polypropene extrusion molding are formed, the diameter of the Loose tube
For 1.8~2.6mm, the wall thickness of the Loose tube is 0.2mm~0.3mm, is provided with multifiber 1, institute in the center beam tube 3
Stating optical fiber 1 can be bulk optical fiber, ribbon fiber or pencil optical fiber, and the optical fiber 1 includes bare fibre and coloring layer, the optical fiber
1 quantity is 4~12, filled with the fine ointment 2 for protecting optical fiber 1 in the center beam tube 3.The center beam tube 3
Outside is successively coated with enhancement layer, sheath 5 and outer jacket 7；The enhancement layer is the glass fiber yarn 4 that blocks water, the glass that blocks water
Glass silvalin 4 not will increase freight relative to metal material glass fibre yarn lighter in weight, more importantly its softness bending
Functional, mechanical performance is in no way inferior with aramid fiber yarn in the case where low in cost；The glass fiber yarn 4 that blocks water simultaneously is nontoxic
Harmless, non-ignitable, corrosion-resistant, high temperature resistant extends small, stable chemical performance, has certain tensile strength, can increase the anti-of optical cable
Performance is drawn, is attached with water-proofing powder on the glass fiber yarn 4 that blocks water, the water-proofing powder plays the role of water swelling, is meeting water
When quickly water suction and itself expand, effectively optical cable can be prevented to seep water.Glass fiber yarn 4 is blocked water described in more at the center
Seamless winding, the twisted coefficient of the twisted winding of the glass fiber yarn 4 that blocks water are twisted on the outside of beam tube 3 are as follows: 1.0119~1.0123,
Guarantee to be bonded to each other between each glass fiber yarn 4 that blocks water and is not overlapped accumulation.Two are embedded in the sheath 5 in parallel
Non-metal reinforcement member 6, the non-metal reinforcement member 6 is arranged in parallel with the center beam tube 3, and the outer jacket 7 is red shield
It covers, is embedded with several glass fiber granules 8 in the outer jacket 7, the glass fiber granules 8 are uniformly embedded in outer jacket 7
Interior, when birds, which sting, pecks outer jacket 7, glass fiber granules 8 can stab birds mouth, and birds will stop pecking stinging, by glass fibre
Particle 8 is embedded into outer jacket 7 in compared with the prior art is arranged the benefit for coating glass fiber reinforcement bar inside outer jacket 7
It is:
1, the flexibility for not influencing optical cable, the optical cable for being coated with glass fiber reinforcement bar increase the bending radius of optical cable,
It is easy to cause bending in the construction process.
2, before birds gnaw through sheath not yet, glass fiber granules 8 will stab birds mouth, it is made to abandon pecking
The glass fiber reinforcement bar stung, and be coated in outer jacket 7 needs just to play the effect of expulsion when birds gnaw through sheath,
Effect is undesirable.
Reference Fig. 2, the technological process of production of the light-duty anti-unfirmly closing optical cable of the utility model:

Purpose is in order to distinguish each optical fiber 1, convenient for welding when construction；
(2) prepared by center beam tube 3: the colored optical fiber 1 after more colorings passes through the extruder of plastic sleeve process, squeezes out central beam
Pipe 3 is coated on the outside of optical fiber 1, and the center beam tube 3 is PBT Loose tube or modified polypropene Loose tube, in the center beam tube 3
It is mixed with the Masterbatch of different colours, causes 3 color of center beam tube squeezed out different, filled with fine ointment in the center beam tube 3
2。
(3) prepared by enhancement layer: the more glass fiber yarns 4 that block water are twisted using cage winch and are coated on 3 outside of center beam tube,
The twisted coefficient that cage winch is arranged is 1.0119, guarantees the pay off rack unwrapping wire in the cage of each cage winch when cage winch is twisted
Tension is identical, it is ensured that multiple glass fiber yarns 4 that block water are evenly distributed on 3 outside of center beam tube and the adjacent glass that blocks water when twisted
There is no gap between silvalin 4.
(4) prepared by sheath 5: protecting extruding machine in being arranged after cage winch, beam tube 3 outer cladding in center is blocked water glass fibre
After yarn 4, center beam tube 3 is entered directly into interior shield extruding machine, the glass fiber yarn that blocks water that extrusion molding sheath 5 will have been coated just
4 position is fixed, while extrusion molding sheath 5 including protect extruding machine two sides respectively penetrate non-metal reinforcement member 6, it is described non-
Metal reinforcement 6 is allowed to parallel with center beam tube 3 by guide wheel and penetrates, and non-metal reinforcement member 6 is embedded into sheath 5 in this way
In.
(5) prepared by outer jacket 7: glass fiber granules 8 being mixed into outer jacket material, glass fiber granules 8 and outer jacket
The proportion of material is 1:10, and glass fiber granules 8 are stirred evenly, and the center beam tube 3 with sheath 5 prepared is penetrated outer
Protect in extruding machine, glass fiber granules 8 and the outer jacket material co-extrusion and go out, formed it is internal embedded with glass fiber granules 8 outside
Sheath 7.
Specifically, the size of the glass fiber granules 8 is 90~150um, and the glass fiber granules 8 of this size squeeze out not
The cable skin of sheath can be caused to scratch, extruding machine will not be externally protected and impact.
Specifically, the outer jacket 7 is nylon sheath wire, and the nylon sheath wire is to be expressed to sheath 5 using extrusion process
On, nylon sheath wire mechanical strength is big, and it is heat-resisting, wear-resistant, considerably increase the mechanical strength of optical cable.
Specifically, two non-metal reinforcement members 6 are separately positioned on the two sides of the center beam tube 3, and distance center
Beam tube 3 is equidistant, and two parallel non-metal reinforcement members 6 are in the same horizontal position and are located at non-metal reinforcement member 6 outer two
5 wall thickness of sheath of side is equal, prevents the sheath skin of sheath 5 from shrinking, while improving cable strength.
Specifically, the non-metal reinforcement member 6 is KFPR round bar.
Embodiment described above is only preferred embodiments for fully illustrating the utility model, the utility model
Protection scope it is without being limited thereto.Those skilled in the art made equivalent substitute or change on the basis of the utility model
It changes, both is within the protection scope of the present invention.The protection scope of the utility model is subject to claims.
