Description
Technical field
The utility model relates to a kind of super soft type and zooms out photoelectric mixed cable, be applied in mobile communication base station, baseband processing unit (BBU) and radio frequency remoto module (RRU) couple together by matching connector or special connector, by optical signal transmission in far-pulling module, carry out power supply supply also to RRU module simultaneously.
Background technology
Along with remote technology application in 3G, 4G build is more and more, dragging optical cable also starts to popularize in the application of base station, but there is now so a kind of phenomenon: dragging optical cable is only responsible for carrying out the transmission of light signal to RRU device, the power supply supply of RRU still adopts separately lays a cable, so not only construction cost adds, and efficiency is also very low.
Summary of the invention
The purpose of this utility model is the defect for prior art, provides a kind of super soft type to zoom out photoelectric mixed cable.Adopt the tight tube structure protection optical fiber with special resin coating, after extruding into single fiber cable and multiply soft copper power line spiral twisted synthesizing cable longitudinal direction wrap up high strength synthetic fibre (PPTA) as strengthening load-bearing component, outside extrudes polyurethane jacket.Overall structure pliability is very good, and bending radius reaches 50mm.
Actualizing technology scheme of the present utility model is: a kind of super soft type zooms out photoelectric mixed cable, the coat (2) of one deck resin is applied outward by optical fiber (1), tight sleeve layer (3) is extruded outside coat (2), tight sleeve layer (3) is longitudinal coated aramid fiber (4) outward, extrude inner sheath (5) outside aramid fiber (4) and form single fiber cable, the stranded mode of spiral is adopted to be twisted into cable core by two single fiber cables and two multiply annealed copper wires (6), strengthen aramid fiber (7) in the outer stranded high strength of cable core, outside aramid fiber (7), extrude polyurethane jacket (8).
Adopt with the tight tube fiber structure of special resin coating, high strength synthetic fibre as reinforcement, appearance sheath composition that ageing-resistant Impact-resistant flexible performance is good, RRU device can be organized power supply is provided, radius of curvature reaches 50mm, described high strength synthetic fibre more than at least 10 strands, guarantees that the tensile force of optical cable is greater than 1500N.
The super soft type of above-mentioned one zooms out photoelectric mixed cable, it is characterized in that: described high strength synthetic fibre is a kind of PPTA; Described appearance sheath adopts the elastomer polyurethane material ageing-resistant, pliability is good; Described tight tube fiber is that one plastic raw materials after bare fiber appearance coating special resin, after high-temperature fusion, is extruded on resin by mold cools down sizing.Power supply can be provided to supply to RRU device.
It is reasonable that the super soft type of one of the present invention zooms out photoelectric mixed cable global design, and compact conformation, fabrication processing is reliable.The super soft type of one through the present invention's making zooms out photoelectric mixed cable and has following features:
1. adopt tight tube fiber structure, there is excellent water resistance, adopt dry type to block water, promote the block-water performance of optical cable.
2. similar is in traditional indoor single core optical cable, becomes end convenient.
3. adopt aramid fiber as load-bearing component, significantly promote the mechanical performance of optical cable.Mechanical stretching force >=1500N, flat pressure >=2200N.
4. power supply while an optical cable transmission light signal, can be provided again to supply.
5. sheath adopts polyurethane material, and make optical cable have excellent pliability, limit curvature radius reaches 50mm, is suitable for indoor, outdoor various environment wiring.
Accompanying drawing explanation
Fig. 1 is that the super soft type of the utility model zooms out photoelectric mixed cable cross-sectional structure schematic diagram.
Embodiment
Below with reference to accompanying drawing, the utility model is described in further detail.
Fig. 1 is that the super soft type of the utility model zooms out photoelectric mixed cable cross-sectional structure schematic diagram.
With reference to accompanying drawing 1, the coat 2 of optical fiber 1 outer coating one deck resin, tight sleeve layer 3 is extruded outside coat 2, the outer longitudinally coated aramid fiber 4 of tight sleeve layer 3, extrude inner sheath 5 outside aramid fiber 4, which constitute single fiber cable, the mode adopting spiral stranded by two single fiber cables and two multiply annealed copper wires 6 is twisted into cable core, strengthen aramid fiber 7 in the outer stranded high strength of cable core, outside aramid fiber 7, extrude polyurethane jacket 8.
A kind of novel super soft type dragging optical cable of the present embodiment takes following scheme to realize: optical fiber is released by pay off rack, through being equipped with the coating cup of resin, through sizing die, optical fiber surface is allowed fully to be coated with last layer resin, through UV curing oven, by the sizing of the resin solidification of coating, enter extruder head by predispersed fiber thermal; Plastic raw materials is in molten condition after machine barrel high temperature is heated, and the optical fiber after coating is good by specific extrusion die protects bag one deck tight sleeve layer, and save after cold dynamic water tank dries up through high temperature, normal temperature two and take-up is coiled, after test passes, circulation enters single fiber cable operation.
Tight tube fiber after test passes is released by pay off rack, multiply aramid fiber forms relatively-stationary position through wire parallel module and tight tube fiber and enters extruder head, plastic raw materials is molten condition after machine barrel high temperature is heated, tight tube fiber and aramid fiber extruded one deck inner sheath by specific extrusion die to enter warm water cooling system and enter cold water again and cool, single fiber cable after sizing after overtension control survey system, take-up is coiled through caliper in production line traction, after lower machine test passes, proceeds to stranding sheath operation.
Two qualified single fiber cables and two multiply annealed copper wires adopt unidirectional cage with fixed knot apart from being twisted into cable core, cable core enters aramid fiber intertwist body, adopt that the aramid fiber of several high strength is unidirectional to be stranded on cable core, jointly enter head, polyurethane elastomer raw material is molten condition after machine barrel high temperature is heated, be extruded on cable core by specific mould, enter warm water cooling system and enter cold water cooling again, after overtension control survey system, take-up is coiled in production line traction through caliper by optical cable after sizing, lower machine carries out performance test.
Although the present invention with preferred embodiment openly as above, they are not for limiting the present invention, anyly haveing the knack of this those skilled in the art, without departing from the spirit and scope of the invention, from when making various changes or retouch, all within protection scope of the present invention.What therefore protection scope of the present invention should define with the claims of the application is as the criterion.
