Abstract
The invention relates to an indoor or outdoor self-supporting armored butterfly-shaped entrance cable comprising a butterfly-shaped cable unit, a metal armored layer wrapped outside the butterfly-shaped cable unit, an aramid yarn layer wound around the metal armored layer, an outer jacket extruded on the periphery of the aramid yarn layer and a hanging wire which is parallel and fixedly connected to the outer jacket, wherein the butterfly-shaped cable unit comprises an optical fiber in the center, an inner jacket and a reinforcing core, the inner jacket is wrapped on the periphery of the optical fiber and provided with a butterfly-shaped cross section, and the reinforcing core is arranged in the inner jacket and is symmetrical relative to the optical fiber. By adding the armored layer around the traditional butterfly-shaped cable unit, the cable provided by the invention can effectively prevent mouse biting, a layer of aramid yarn is wound on the periphery of the armored layer to enhance the side-compression-resistant performance of the optical fiber and the tensile resistance of the optical fiber. Accordingly, the mechanical performance and the environmental resistance of the optical fiber can be greatly improved.
Description
Technical field
The present invention relates to a kind of communications optical cable.
Background technology
Existing self-bearing type butterfly optical cable structure as shown in Figure 1, the cross section that it comprises optical fiber 10, be coated on the optical fiber periphery be butterfly sheath 20, be arranged in the sheath 20 and be positioned at the strengthening core 30 of optical fiber 10 both sides, the messenger wire 40 that is connected with sheath 20.Wherein, strengthening core 30 is made by metal or nonmetallic materials.In use there is following shortcoming in this kind self-bearing type butterfly optical cable:
1, be used for outdoorly when built on stilts, optical cable acts directly on the optical fiber running into external impacts moment, causes fibercuts easily or damage is arranged;
2, indoor and outdoor optical cable does not add anti-mouse material, and therefore well not anti-mouse stings function and lateral pressure resistant power after laying;
3, after Fiber to the home, the mouse bite preventing self-support cable need be used in the mountain area, and conventional self-bearing type butterfly leading in cable can't satisfy its environment for use;
4, China is in the initial stage that FTTX optical fiber is registered one's residence at present; optical cable for optical fiber to house is laying in batches, but after this kind optical cable is used for the indoor and outdoor fiber cable laying in mountain area, occurs being bitten broken optical fiber and loss increase phenomenon by mouse through regular meeting; cause line interruption, the circuit emergency repair cost is than higher.
Summary of the invention
The object of the invention provides a kind ofly to be possessed anti-mouse and stings indoor and outdoor that function can be used for indoor use simultaneously with self-bearing type armouring butterfly leading in cable outdoor.
In order to reach the foregoing invention purpose, technical scheme of the present invention is: a kind of indoor and outdoor self-bearing type armouring butterfly leading in cable, it comprises butterfly optical cable unit, wrapped metal armouring layer, the aramid fiber layer that is wrapped in described metal armouring layer, extrusion molding outside described butterfly optical cable unit at the oversheath of described aramid fiber layer periphery, the messenger wire parallel and fixedly connected with oversheath, described butterfly optical cable unit by the optical fiber that is positioned at the center, be coated on optical fiber periphery and xsect be butterfly inner sheath, be arranged on inner sheath and form with respect to the strengthening core of optical fiber symmetry.
Further, described messenger wire is made up of reinforcement, the support set that is coated on the reinforcement periphery, and described support set and oversheath one extrusion moulding.
Described reinforcement is made by metal material.
The strengthening core of described butterfly optical cable unit is made by nonmetallic materials.
Adopt such scheme, the present invention compared with prior art has following advantage: having increased armor can prevent that effectively mouse stings to optical cable of the present invention all around in existing butterfly optical cable unit, the peripheral one deck aramid yarn that twines of armor, can increase the lateral pressure resistant power performance of optical cable and increase stretching resistance, therefore, the mechanical property of optical cable and environmental resistance are greatly improved.

Embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the present invention is elaborated:
Optical cable as shown in Figure 2, it comprise butterfly optical cable unit 1, wrapped on butterfly optical cable unit 1 metal armouring layer 2, be wrapped in the aramid fiber layer 3 of metal armouring layer 2 periphery, the messenger wire 5 that is coated on oversheath 4 on the aramid fiber layer 3, is fixedly connected with oversheath 4.
Wherein, butterfly optical cable unit 1 is made up of the colored optical fiber 11 that is arranged in the center, the strengthening core 13 that is coated on the inner sheath 12 of optical fiber 11 peripheries and is arranged on inner sheath 12.Inner sheath 12 xsects are butterfly, and it is made by the low smoke and zero halogen polythene material.Strengthening core 13 is made for nonmetallic materials, the preferred FRP strengthening core of present embodiment.
Messenger wire 5 is made up of metal reinforcing 51 and the support set 52 that is coated on reinforcement 51 peripheries, and support set 52 is also made for the low smoke and zero halogen polythene material, in the present embodiment, and support set 52 and oversheath 4 one extrusion moulding.
Optical cable of the present invention increases armor around in the butterfly optical cable unit, can prevent that effectively mouse stings, and by at the peripheral one deck aramid yarn that twines of armor, can increase the lateral pressure resistant power performance of optical cable and increase stretching resistance.Whole cable outer diameter is 7.0*11.7mm.
And in manufacture process, the laying tension by adjusting the armouring pipe and the lay of lapping of aramid yarn can solve problem that armor is elongated easily and the aramid yarn problem with armouring pipe uniform winding.And after whole production technology can utilize the assembling of existing distribution plant, directly put into production, need not increase equipment investment.
The foregoing description only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage who is familiar with this technology can understand content of the present invention and enforcement according to this; can not limit protection scope of the present invention with this; all equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
