Description
Technical field
The utility model relates to a kind of optical cable, especially a kind of outdoor organdy rodent-resistant cable.
Background technology
Along with the development that deepens continuously of optical-fibre communications, the use of optical cable is more and more universal, and different environments for use requires different to optical ca ble protection.In the more serious area of some plagues of rats, the situation that optical cable is bitten broken by the muroid animal often occurs, bring great difficulty to line upkeep.For factors such as ecological environmental protection and feasibilities, the protection against rodents of lightguide cable link can not be taked the measures such as poisoning and trapping, and the optical cable that therefore has anti-rat becomes the selection of each common carrier.The protection against rodents method of optical cable mainly is divided into chemical protection against rodents and physics protection against rodents.From environmental protection and persistent angle, the physics protection against rodents is more practical than chemical protection against rodents.The physics protection against rodents mainly is divided into two classes, and a class is to utilize the hardness of cable material to reach the purpose that resists damaged by rats, and is common as the hard metal steel-tape armouring is set in optical cables heavy, or thin round steel wire or FRP rod etc.; One class is to utilize the acuteness of rodent-proof material to come the puncture muroid, makes the mouse tooth be difficult to gnaw through or is felt bad by organdy puncture oral cavity, thereby reach the purpose of protection cable core, common are the organdy protection against rodents.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art; provide a kind of acuteness of rodent-proof material of utilizing to come the puncture muroid; make the mouse tooth be difficult to gnaw through or felt bad by organdy puncture oral cavity, thereby reach the outdoor organdy rodent-resistant cable of protection cable core purpose.
The technical scheme that provides according to the utility model, described outdoor organdy rodent-resistant cable, in oversheath, be provided with organdy, in organdy, be provided with inner sheath, in inner sheath, be provided with waterstop, in waterstop, be provided with central reinforce member, between the inside surface of the outside surface of central reinforce member and waterstop, be provided with loose sleeve pipe, in loose sleeve pipe, be provided with optical fiber, in loose sleeve pipe, be filled with fine cream, be wound with water blocking yarn at the outside surface of central reinforce member.
The outside diameter of described loose sleeve pipe is 1.75 ~ 1.85mm.Described loose sleeve pipe adopts polybutylene terephthalate to make.
The thickness of described inner sheath is 0.6 ~ 1.0mm.Density PE material was made during described inner sheath adopted.
The thickness of described oversheath is 1.6 ~ 2.0mm.Described oversheath adopts high density PE material to make.
The utlity model has following advantage:
1, the optical cable of the utility model formation is soft, good bending property;
2, less demanding to equipment of the utility model, moulding is easy;
3, outdoor organdy rodent-resistant cable diameter described in the utility model is little, lightweight, can guarantee that cable can satisfy strain and the decay requirement of optical cable and optical fiber itself in the installation and operation process.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: this outdoor organdy rodent-resistant cable, in oversheath 9, be provided with organdy 8, in organdy 8, be provided with inner sheath 7, in inner sheath 7, be provided with waterstop 6, in waterstop 6, be provided with central reinforce member 1, between the inside surface of the outside surface of central reinforce member 1 and waterstop 6, be provided with 6 loose sleeve pipes 5,6 loose sleeve pipes 5 are wrapped on the central reinforce member 1, in every loose sleeve pipe 5, be provided with 4 optical fiber 3, in loose sleeve pipe 5, be filled with fine cream 4, be wound with water blocking yarn 2 at the outside surface of central reinforce member 1.
The outside diameter of described loose sleeve pipe 5 is 1.75 ~ 1.85mm.Described loose sleeve pipe 5 adopts PBT material (polybutylene terephthalate, English name polybutylene terephthalate) to make.
The thickness of described inner sheath 7 is 0.6 ~ 1.0mm.Density PE material was made during described inner sheath 7 adopted.
The thickness of described oversheath 9 is 1.6 ~ 2.0mm.Described oversheath 9 adopts high density PE materials to make, and can play antiultraviolet, anticorrosion, shockproof effect to the pipeline cable.
Have 6 loose sleeve pipes 5, in each loose sleeve pipe 5, comprise 4 optical fiber 3; Do not affect the performance of optical fiber 3 when loose sleeve pipe 5 is expanded with heat and contract with cold, in each loose sleeve pipe 5, fill fine cream 4; Described central reinforce member 1 guarantees cable when being subject to maximum installation pulling force and maximum operation pulling force in order to the stress requirement of cable to be provided, and optical fiber 3 strains meet the requirements of numerical value; Described organdy 8 is in order to provide the effect of optical cable protection against rodents, and the weight of the organdy 8 of placement is 20g/m.
The outdoor organdy rodent-resistant cable of 24 cores of the present utility model overlaps operations at the outside of optical fiber 3 extrusion molding PBT pine sleeve pipe 5 by two first, water blocking yarn 2 is on central reinforce member 1, the mode of pine sleeve pipe 5 by S-Z layer strand be wrapped in central reinforce member 1 around, total is fixed with the bundle yarn, forms cable core structure; Waterstop 6 wraps in whole cable core structure outside, and middle density PE inner sheath 7 extrusion moldings are outside waterstop, and organdy 8 is placed on the inner sheath outside, and high density PE oversheath 9 extrusion moldings are in the outside of organdy 8, thus formation cable body.
