Preferably, antisitic defect optical cable also comprises gasket for packing, and this gasket for packing is looped around the outside of central reinforce member.
Compared with prior art, the beneficial effects of the utility model are: the Kev in the utility model draws tissue layer lighter weight, but there is higher antibody Monoclonal ability, and mutually adhere between itself and Organic bushing pipe, further increase the antibody Monoclonal ability of optical cable, thus achieve the antisitic defect optical cable of lightweight.
[accompanying drawing explanation]
The structural representation of a kind of antisitic defect optical cable that Fig. 1 provides for the utility model embodiment;
Fig. 2 is the structural representation of another embodiment of the utility model.
[embodiment]
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
In addition, if below in described each embodiment of the utility model involved technical characteristic do not form conflict each other and just can mutually combine.
embodiment 1:
The utility model example 1 provides a kind of antisitic defect optical cable.The structural representation of a kind of antisitic defect optical cable that Fig. 1 provides for the utility model embodiment, as shown in Figure 1, antisitic defect optical cable comprises inner sleeve 101, central reinforce member 102, Loose tube 103, optical fiber 104, Kev draw tissue layer 105, Organic bushing pipe 106.
As shown in Figure 1, inner sleeve 101 is hollow layer, its role is to hold and dead center reinforcement 102 and many Loose tube 103 therein.In the present embodiment, inner sleeve 101 is made up of bundle layer, and pricking yarn is the binding tools such as a kind of conventional cable.In order to carry out waterproofing protection to internal part, preferably, the inside of inner sleeve 101 is filled with waterproof cable cream.
Central reinforce member 102 is positioned at the center of inner sleeve 101, its role is to provide certain toughness to optical cable, therefore its needs are the materials with certain toughness, preferably, central reinforce member in the present embodiment is fibre reinforced plastic tube, such as tempered glass pipe, carbon fiber reinforced plastics pipe, aromatic polyamide fiber reinforced plastics pipe etc.Loose tube 103 is looped around the surrounding of central reinforce member 102, and near central reinforce member 102.Now Loose tube 103 and central reinforce member 102 are housed inside in inner sleeve 101.It is inner that optical fiber 104 is arranged at Loose tube 103, and the inside of Loose tube 103 is filled with fine cream to fix and to protect optical fiber 104.
In order to protect optical cable inner structure not damaged; in prior art, a lot of optical cable is at the outer setting armor of inner sleeve 103; this armor is made up of wrinkle steel band, coated steel band or steel wire; therefore the weight of this optical cable considerably increases on the one hand; the pliability of its optical cable also greatly reduces on the other hand, is not easy to install.In order to address this problem, in the present embodiment, optical cable is provided with one deck Kev and draws tissue layer 105 to be coated on the outside of inner sleeve 101.It is the fabric of being worked out by Kafra fiber that Kev draws fabric a kind of, and Kafra fiber is different from general fiber, and its proportion only has 1/5th of steel, but toughness and tensile strength are very high, therefore when Kev draws tissue layer 105 to be subject to impacting, is not easy to damage.In addition, what deserves to be explained is, in prior art, optical cable is generally easy to be damaged by sharp objects, because when sharp objects is to optical cable externally applied forces, pressure is very large, is easy to penetrate from optical cable weakness.But in the present embodiment, Kev draws fabric to be formed by the fiber interweaving of vertical and horizontal, when sharp objects thrust Kev draw tissue layer 105 time, Kafra fiber around sharp objects can slide to both sides, but because tenacity of fibre is higher, fiber can have self-locking action to the tip of sharp objects after slippage a little, thus stops sharp objects to enter optical cable inside further.Find in an experiment, if will realize good self-locking effect, Kev draws fabric must have certain tight ness rating, and the Kev therefore in the present embodiment draws the surface density of tissue layer to be more than or equal to 500g/m
2.
In addition, in the present embodiment, Organic bushing pipe 106 is coated on Kev and draws tissue layer 105 outside, and draws tissue layer 105 adhesion with Kev.The material material of Organic bushing pipe 106 is organic resin, such as tygon, Polyvinylchloride etc.When outer tube 106 and Kev draw tissue layer 105 adhesion, due to the reason of molecular structure, organic resin can draw tissue layer to have good adhesion with Kev, if optical cable is subject to external force, Kev draws tissue layer 105 to produce distortion under external force, and due to adhesion, the fiber of distortion place can drive Kev to draw the bulk deformation of tissue layer 105, thus the impact energy of external force is offset by moderate finite deformation, therefore this further improves the anti-damage ability of optical cable.
It should be noted that, inner sleeve 103 in the present embodiment is 5, and in other embodiments of the present utility model, the quantity of Loose tube 103 also can be arranged as required, such as Fig. 2 is the structural representation of another embodiment of the utility model, as shown in Figure 2, in the present embodiment, antisitic defect optical cable comprises inner sleeve 201, central reinforce member 202, Loose tube 203, optical fiber 204, Kev draw tissue layer 205, Organic bushing pipe 206.Wherein, optical cable is provided with 3 Loose tube 203, and in order to keep distribution equilibrium to fix, optical cable further comprises the outside that 2 gasket for packings are looped around central reinforce member 202.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
