In order to overcome the defective that exists in the background technology, the technical scheme that its technical matters that solves the utility model adopts is: this full medium central beam tube type communications optical cable, it is by optical fiber, fine cream, optical fiber bundle tubes, strengthen element, waterstop, sheath constitutes, pass through fine cream fixed fiber in the optical fiber bundle tubes, be provided with the enhancing element of a flexible fiber reinforced plastic between optical fiber bundle tubes and the waterstop, this enhancing element is made fortifying fibre is bonding by thermoplastic EVA resin, and the waterstop outside is with sheath.
According to another embodiment of the present utility model, full medium central beam tube type communications optical cable comprises that further described EVA resin is an ethylene-vinyl acetate copolymer.
According to another embodiment of the present utility model, full medium central beam tube type communications optical cable comprises that further described fortifying fibre is ultra high modulus polyethylene fibre or glass fibre or aramid fiber fortifying fibre.
According to another embodiment of the present utility model, full medium central beam tube type communications optical cable comprises that further described optical fiber bundle tubes adopts the polybutylene terephthalate material to make.
According to another embodiment of the present utility model, full medium central beam tube type communications optical cable comprises that further described waterstop adopts vertical bag or wrapped mode to be connected with sheath.
According to another embodiment of the present utility model, full medium central beam tube type communications optical cable comprises that further described cable jacket is polyethylene sheath material or low-smoke halogen-free polyolefin protective cover material or anti-electric-mark protective cover material.
The utility model has solved the defective that exists in the background technology, and its beneficial effect is:
1, the scope of application enlarges
This structure optical cable does not comprise metal material, therefore is easy to use at highfield and electric power lightning protection zone.
2, long service life
This structure adopts the fine cream of thixotropy, is used for protection against the tide and stress protection to the optical fiber of beam tube, thereby prevents the static fatigue of optical fiber, guarantees the serviceable life of optical fiber.
3, this structure optical cable does not have the steel wire reinforcing element, and the fibre reinforced plastics of vertical bag are soft, are beneficial to the optical cable bending.And simple in structure, external diameter reduces, and weight saving is beneficial to install and lays.
4, production run is simple
Only need direct seamless vertical bag fibre reinforced plastics reinforcing band outside the beam tube of center, extrude sheath simultaneously and get final product, do not need overlap joint, without any need for binding material, product is easy to moulding.
5, good stability
Because strengthening the composite plastic reinforcing element, flexible fiber adopt thermoplastics as bonding agent, so extrude in the process at cable jacket, the reinforcing element of stranded fibre-reinforced plastics has adhesion to a certain degree between adjacent, thereby has increased the stability of cable configuration.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
Wherein: 1, optical fiber, 2, fine cream, 3, optical fiber bundle tubes, 4, strengthen element, 5, waterstop, 6, sheath.
Embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the synoptic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
This full medium central beam tube type communications optical cable, it is by optical fiber 1, fine cream 2, optical fiber bundle tubes 3 strengthens element 4, waterstop 5, sheath 6 constitutes.By fine cream 2 fixed fibers 1, be provided with a circle enhancing element 4 between optical fiber bundle tubes 3 and the waterstop 5 in the optical fiber bundle tubes 3, this enhancing element 4 is made fortifying fibre is bonding by thermoplastic EVA resin, and waterstop 5 outsides are with sheath 6.The EVA resin is an ethylene-vinyl acetate copolymer, is by ethene and vinyl acetate copolymerization and make, and the EVA English name is: Ethylene VinylAcetate.Described fortifying fibre is ultra high modulus polyethylene fibre or glass fibre or aramid fiber fortifying fibre.
The characteristics of EVA resin are to have good flexibility, and the elasticity as the rubber still can have pliability preferably under-50 ℃, and the transparency and surface gloss property are good, and chemical stability is good, and anti-aging and anti-ozone intensity is good, avirulence.Good with the miscibility of filler, painted good with processing and forming.
EVA resin and vinyl acetate content and molecular weight, melt index (MI) concern very big.When melting index (MI) certain, when vinyl acetate (VA) content improves, its elasticity, flexibility, intermiscibility, the transparencys etc. are also along with improve.When VA content reduced, then the EVA resin property approached tygon, and rigidity increases, and wearing quality, electrical insulating property improve.
The full medium central tubular of this multi-usage optical cable can be used as the indoor and outdoor branch line of Metropolitan Area Network (MAN), LAN (Local Area Network) or Access Network, and its inner wire is made by optical fiber 1.The outside of optical fiber 1 is filled and is adopted the fine cream of thixotropy, is used for protection against the tide and stress protection to the optical fiber of beam tube, both as the stationkeeping thing of optical fiber 1, again as insulation course.Be shaped on one deck optical fiber polybutylene terephthalate beam tube 3 in the outside of fine cream 2 as bearing layer, the enhancing element 4 of the fibre-reinforced plastics of beam tube 3 outsides further strengthens the pulling force of this optical cable.Be shaped on the moisture barrier of the optical cable core of a circle waterstop 5 formations in enhancing element 4 outsides of fibre-reinforced plastics.Waterstop can adopt vertical bag or wrapped mode.Be shaped on a sheath 6 in water blocking tape 5 outsides at last, adopt black polyethylene protective cover material or low-smoke halogen-free polyolefin protective cover material to make, during as All Dielectric self-support, also adopt the anti-electric-mark protective cover material to make.
When the full medium central tubular of this multi-usage optical cable is used as All Dielectric self-support, should be according to required span, sag and meteorological condition and the optical cable of estimating weight, calculate the required optical cable pulling force that bears, thereby try to achieve the diameter and the radical of fibre-reinforced plastics rope, determine the external diameter of center beam tube again.When span is bigger, when meteorological condition was relatively poor, the radical of the enhancing element 4 of required fibre-reinforced plastics can adopt the opposite double-deck lay configuration of direction of lay more for a long time.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the instructions, must determine its technical scope according to the claim scope.
