Abstract
A kind of armored optical cable, comprises at least cable core containing an optical fiber; Seal the sheath (4) of above-mentioned cable core; Seal the metal armouring layer of above-mentioned sheath; The disposable shield sleeve of suit said structure.Wherein cable core is by being made up of fibre bundle (1), reinforcement (2), loose sleeve pipe (3) and necessary packing material; Metal armouring layer is made up of wire armoring layer (5) and metal hangnail armor (6).Wire armoring layer is wrapped and is formed by stainless steel steel wire, metal hangnail armor is to utilize the metal tape that " V " font or other analogous shape otch are set, and welds or axial wrapped mode is arranged at wire armoring layer periphery and makes the outside perk of otch form hangnail by longitudinal wraparound; By being rationally set, size incision and position can take into account armor intensity by natural torsion to ensure armored optical cable simultaneously; Because this armor has certain intensity, can save the reinforcement in cable configuration in some specific occasion, thereby increase cable inner fiber bundle quantity, and then can improve optical cable capacity.The disposable sleeve encapsulation that use is easy to peel off or band wrapping hangnail, to prevent hangnail injury to people in optical cable packaging, transport and installation process.That this cable configuration has is anti-climbing, protection against rodents, antitheftly cut, can natural torsion etc. feature.Armor of the present utility model is also applicable to cable.
Description
Technical field
Patent of the present invention relates to a kind of armored optical cable structure and principle of work thereof of novelty, belongs to the technical field of Optical Fiber Transmission.
Background technology
Armored optical fiber cable has important application in telecommunication optical fiber intercity line, a secondary primary transmission.General armored optical cable structure is tightly packaged fiber+stainless steel flexible hose (playing resistance to compression, counter-bending, mouse bite preventing)+stainless steel braided wires (plaing a part antitorque)+oversheath.Advantage is high tensile, high resistance to compression, mouse bite preventing and unfirmly closing; Possess and can resist the damage of torsional bending improperly; Adapt to various rugged surroundings and artificial damage.Shortcoming is that stainless steel soft pipe processing technique complexity is set in optical cable inside, and optical cable can not natural torsion to use metal hard tube instead, and metal level is arranged at optical cable nexine and makes oversheath be easy to damage.Prevent that for avoiding above-mentioned shortcoming to take into account robber's outdoor optical cable in community from entering in resident family, special propose a kind ofly there is anti-climbing, the anti-bird of protection against rodents, antitheftly cut, can natural torsion etc. the cable configuration of feature.
Summary of the invention
Technical matters: technical matters to be solved by this invention is to provide a kind of cost of manufacture low for above-mentioned the deficiencies in the prior art, the Novel armored optical cable that processing technology is comparatively easy.
Technical scheme: the technical scheme of a kind of armored optical cable of the present invention is: include cable core, sheath and metal double armature layer and disposable shield sleeve, be that with existing scheme difference armor is arranged on sheath periphery, be provided with wire armoring layer 5 and metal hangnail armor 6 double-deckers, be provided with disposable protection tube 7 with instant packed, transport and installation in this double-decker periphery.
Press such scheme, described cable core and sheath comprise fibre bundle 1, reinforcement 2, and loose sleeve pipe 3, sheath 4 and necessary packing material, its essence is traditional cable configuration; Described metal armouring layer is along the axial wire armoring layer of laying 5 of cable core and the metal armouring layer 6 with hangnail; Disposable protection tube 7 employings are easy to disposable pull tube material or the structure peeled off with metal hangnail armor 6.
Described metal double armature layer structure internal layer is preferably stainless steel steel wire part and is wrapped and forms, outer for metal hangnail armouring part that can natural torsion and with aforesaid steel wire part fully in conjunction with forming a kind of composite structure acting in conjunction, make described optical cable there is anti-climbing, the anti-bird of protection against rodents, antitheftly cut, can natural torsion etc. feature.Metal hangnail armor should use the metal material with antiseptic and rustproof function to be made, be preferably stainless steel, can utilize the metal tape of setting " V " font or other analogous shape otch, weld or axial wrapped mode is arranged at wire armoring layer periphery and makes the outside perk of otch form hangnail by longitudinal wraparound; Metal tape becomes and is easy to bending owing to having numerous otch, can take into account armor intensity by natural torsion by size incision and position are rationally set to ensure armored optical cable simultaneously; Because this armor has certain intensity, can save the reinforcement in cable configuration in some specific occasion, thereby increase cable inner fiber bundle quantity, and then can improve optical cable capacity.
Beneficial effect: be that outermost layer arranges double armature layer, adopt such cable configuration, beneficial effect for (1) metal hangnail be conducive to prevent the climbing of muroid and bait, the standing and peck and sting of birds; (2) metal hangnail is conducive to prevent that the mankind's climbing and robber from cutting; (3) metal hangnail armouring can adopt the longitudinal wraparound welding of metal tape or axial wrapped mode to process, and compares traditional stainless steel flexible hose armouring, simplifies production technology; (4) metal hangnail armouring is lower than directly adopting metal sleeve armouring hardness, can have with advantages such as cable core natural torsions.
Brief description of the drawings
Fig. 1 is the cross-sectional structure schematic diagram of armored optical cable.
Fig. 2 hangnail structural representation.
In figure, there are 1. fibre bundles, 2. reinforcement, 3. loose sleeve pipe, 4. sheath, 5. wire armoring layer, 6. hangnail armor, 7. disposable protection tube.Wherein fibre bundle 1, reinforcement 2, loose sleeve pipe 3 and necessary packing material form traditional optical cable core.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with embodiment, further illustrate the present invention.
As shown in Figure 1, a kind of armored optical cable, comprises by fibre bundle 1, reinforcement 2, loose sleeve pipe 3 and necessary packing material and forms traditional optical cable core, sheath 4 and the armor being made up of wire armoring layer 5, metal hangnail armor 6 and the disposable protection tube 7 of encapsulation.
Embodiment 1
Armored optical cable of the present invention can additional three-decker form on the basis of conventional cable, wire armoring layer is wrapped and is formed by stainless steel steel wire, be wound around density can be close can be rare, thereby its Main Function for strengthening metal hangnail armor intensity, provide support and make hangnail armor and sheath coupling well due to flexible; Metal hangnail armor material can select metal that resistance to corrosion is strong as stainless steel, alloy aluminum etc., the otch of " V " font or other analogous shape is set on metal tape, weld or longitudinal lapping mode is closely set in wire armoring layer outside by axial wraparound, as shown in Figure 2, the outside perk of otch and form hangnail, for ensureing hangnail armor intensity and can, with cable core natural torsion, size incision and position should being rationally set; The temporary casing encapsulation hangnail that use is easy to peel off, to prevent hangnail injury to people in optical cable packaging, transport and installation process.Armor of the present invention also can be used for cable.
Embodiment 2
Because this armor has certain intensity, difference from Example 1 is, saves the reinforcement in cable configuration, thereby increases cable inner fiber bundle quantity, and then can improve optical cable capacity.
Embodiment 3
Be with embodiment 1 or 2 differences, use the strap that is easy to tear to be wound around wrapping and replace temporary casing.
