Abstract
The utility model discloses a steel wire armored central bundle tube type optical cable with a worm and ant prevention outer sheath. The cable comprises optical fibers. A central portion is provided with a plurality of optical fibers which are sleeved with a PBT loose tube. Fiber paste is filled between the optical fibers and the PBT loose tube. A plurality of phosphorized steel wires are arranged around the PBT loose tube in a circle. The phosphorized steel wires are wrapped by a belting layer. Cable paste is filled between the PBT loose tube and the belting layer. The belting layer is wrapped by a steel-plastic composite belt which is wrapped by a PE outer sheath which is wrapped by the worm and ant prevention outer sheath. According to the utility model, through setting a steel wire armored structure outside the PBT loose tube, stress resistance ability is good and reaches a bulletproof level, overall flexibility and bending resistance ability of the cable are good, at the same time, the steel-plastic composite belt is installed in the PE outer sheath, the waterproof cable paste is filled in a cable core, thus tide blocking and waterproof effects of the cable are good, the nylon worm and ant prevention outer sheath is arranged outside the cable, termite damage prevention ability is good, and the security of the cable is effectively ensured.
Description
Technical field:
The utility model relates to field fiber, relates in particular to a kind of wire armoring central beam tube type optical cable with insect protected ant overcoat.
Background technology:
Mostly existing optical cable is that optical fiber is with sleeve pipe outward, and cooperates the structure of oversheath, and its mechanical property is relatively poor; Go wrong easily when growing apart from backguy, secondly cable outer sheath adopts the PE sheath usually, and its pressure-proof and snap-resistent ability is relatively poor; In case dug or bump by mistake, be easy to occur situation such as breakage, fracture by mistake; Simultaneously can't the insect protected ant gnaw to bite and cause cable failure, can't lay in the place that the worm ant haunts.Therefore imagination provides a kind of new construction to solve this problem.
The utility model content:
The purpose of the utility model just provides a kind of wire armoring central beam tube type optical cable with insect protected ant overcoat, solves existing optical cable and is mostly that optical fiber is with sleeve pipe outward, and cooperate the structure of oversheath; Its mechanical property is relatively poor; Go wrong easily when growing apart from backguy, secondly cable outer sheath adopts the PE sheath usually, and its pressure-proof and snap-resistent ability is relatively poor; In case dug or bump by mistake, be easy to occur situation such as breakage, fracture by mistake; Simultaneously can't the insect protected ant gnaw to bite and cause cable failure, the problem that can't lay in the place that the worm ant haunts.
The technical scheme that the utility model adopts is:
A kind of wire armoring central beam tube type optical cable with insect protected ant overcoat; Comprise optical fiber: central part has some optical fiber, and some optical fiber are set with PBT pine sleeve pipe outward, is filled with fine cream between optical fiber and the PBT pine sleeve pipe; PBT pine sleeve pipe periphery makes a circle and has some phosphatization steel wires; The phosphatization steel wire is wrapped with belting layer, is filled with cable cream between PBT pine sleeve pipe and the belting layer, and belting layer is wrapped with composite steel-plastic belt; Composite steel-plastic belt is wrapped with the PE oversheath, and the PE oversheath is wrapped with insect protected ant oversheath.
Said belting layer is that the coiling of tygon band forms.
Said insect protected ant oversheath is that nylon is processed.
Compared with prior art, the beneficial effect of the utility model is:
The utility model is through being provided with steel wire armoured structure outside PBT pine sleeve pipe, compressive resistance is good, reaches shellproof rank, and optical cable overall flexibility and counter-bending ability are good; Simultaneously in the PE oversheath, install composite steel-plastic belt additional, fill waterproof cable cream in the cable core, it is good to make optical cable keep off damp waterproof effect; Optical cable is provided with nylon insect protected ant overcoat outward, and termite-proof damage capability is good, effectively guarantees optical cable safety.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is done further explain through embodiment:
A kind of wire armoring central beam tube type optical cable with insect protected ant overcoat, comprise optical fiber: central part has some optical fiber 1, the some optical fiber 1 outer PBT pine sleeve pipes 2 that are set with; Be filled with fine cream 3 between optical fiber 1 and the PBT pine sleeve pipe 2, PBT pine sleeve pipe 2 peripheries make a circle and have some phosphatization steel wires 4, and phosphatization steel wire 4 is wrapped with belting layer 5; Be filled with cable cream 6 between PBT pine sleeve pipe 2 and the belting layer 5; Belting layer 5 is wrapped with composite steel-plastic belt 7, and composite steel-plastic belt 7 is wrapped with PE oversheath 8, and PE oversheath 8 is wrapped with insect protected ant oversheath 9; Belting layer 5 forms for the coiling of tygon band, and insect protected ant oversheath 9 is processed for nylon.
The foregoing description is merely the preferred implementation of the utility model, and in addition, the utility model can also have other implementations.Need to prove that under the prerequisite that does not break away from the utility model design, any conspicuous improvement and modification all should fall within the protection domain of the utility model.
