Abstract
The utility model discloses a reinforced type outdoor broadband cable which comprises a jacket and a cable core. A cross section of the jacket is composed of a round large end and a round small end into one body, the cable core which is intertwisted by one to twenty pairs of twisted pair wires with different intertwisting pitches is wrapped in the large end of the jacket, a layer of polyester belt is arranged between the cable core and the jacket, and each pair of twisted pair wires is intertwisted by two core wires, a high-intensity phosphating steel wire reinforced piece which is wrapped in the small end of the jacket is arrayed with the cable core wrapped with the polyester belt in a parallel manner. As a high-intensity phosphating steel wire is additionally arranged as a reinforced element, the reinforced type outdoor broadband cable can be directly laid across buildings and roads without penetrating through pipes or bridging steel twisted wires.
Description
Technical field:
The utility model relates to a kind of outdoor wide-band cable, particularly a kind of reinforced outdoor wide-band cable.
Technical background:
Along with the arrival of information age, digital communication obtains more and more widely application with broadband cable, and traditional broadband cable is circular, is made up of sheath and cable core, and self no reinforcing element can only poling or lay along wall; When needs are crossed over building, road etc., must set up steel strand wire in advance and lay with hook, extremely inconvenient, the invar twisted wire can't fixedly cause and can't construct sometimes.
Summary of the invention:
Technical problem to be solved in the utility model provides and a kind ofly is adapted to complex environment, can directly lay, need not poling or set up the reinforced outdoor wide-band cable of steel strand wire.
In order to solve the problems of the technologies described above, the utility model has adopted a kind of so reinforced outdoor wide-band cable, comprises sheath and cable core; The cross section of described sheath is combined into one by the big end and the circular small end of circle; At least be wrapped in the big end of described sheath by a pair of above stranded cable core that forms of twisted pair wire, also have one deck polyester belt between cable core and the sheath; Every pair of twisted pair wire is formed according to certain twisting pitch is stranded by two heart yearns, and the heart yearn of twisted pair wire is made up of a conductor and coated insulating barrier in this conductor appearance; Also have a high strength phosphatization steel wire reinforcement to be wrapped in the small end of described sheath, this high strength phosphatization steel wire reinforcement is arranged in parallel with the cable core that has wrapped up polyester belt.
Described cable core is by stranded the forming of a pair of twisted pair wire to 20 pairs of different twisting pitch.
The insulating barrier of the conductor of diameter 0.51 ± 0.01mm that the heart yearn of described twisted pair wire is made by an oxygen-free copper bar material and the coated thickness 0.2 ~ 0.23mm that is made by high-density polyethylene material outside this conductor is formed.
The beneficial effects of the utility model are:
1, the utility model is provided with high strength phosphatization steel wire as reinforcing element, can satisfy product and cross over directly laying of building, road etc., and convenient construction reduces laid down cost.
2, the utility model plays the effect of retaining tidal rip heat fixation cable core at cable core outer wrapping one deck polyester belt.
3, the twisting pitch difference of every twisted pair wire, the pitch configuration by suitable can change electromagnetic field and distribute, and improves the crosstalk attenuation performance.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the cross-sectional structure schematic diagram of reinforced outdoor wide-band cable.
Embodiment:
Embodiment is as shown in Figure 1: a kind of reinforced outside cable, comprise sheath 7, cable core 4 and a high strength phosphatization steel wire reinforcement 6, and the cross section of sheath 7 is combined into one by the big end and the circular small end of circle.Cable core 4 is wrapped in the big end of sheath 7, by four pairs of twisted pair wires, 3 stranded forming, also has one deck polyester belt 5 between cable core 4 and the sheath 7.Every pair of twisted pair wire 3 is by two stranded forming of heart yearn, the heart yearn of twisted pair wire 3 by an oxygen-free copper bar material make, the conductor 1 of diameter 0.51 ± 0.01mm and coated high-density polyethylene material in this conductor 1 appearance is made, the insulating barrier 2 of thickness 0.2 ~ 0.23mm is formed; The twisting pitch of these four pairs of twisted pair wires has nothing in common with each other through well-designed.High strength phosphatization steel wire reinforcement 6 is wrapped in the small end of described sheath 7, and this high strength phosphatization steel wire reinforcement 6 is arranged in parallel with the cable core 4 that has wrapped up polyester belt 5.
Sheath 7 is made by the black polyethylene material of resisting environmental stress and cracking, has strengthened anti-ultraviolet radiation ability and humidity resistance, the outdoor adverse circumstances of product adaptation.
