Description
Technical field
The utility model relates to field of cables, particularly relates to the anti-tampering cable for digital communication of a kind of reinforcement.
Background technology
At present, along with the development of science and technology, the communications field is all at rapid advances, and in the field of communications, telecommunication cable is as the medium of transmission of signal, its consumption is also increase gradually, telecommunication cable normally has several or several groups of wires often to organize the cable of at least two stranded similar ropes, , whole outside is surrounded by the cover layer of high-insulation, the kind of cable has a lot, the environment for use that can be applied in fields different in a lot of field is different, therefore different requirements is also had to cable, but existing cable because of its structural design unreasonable, in the process of telecommunication cable signal transmission, be easy to the interference being subject to external electromagnetic signal, a lot of inconvenience is brought to people's life.
Utility model content
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide the anti-tampering cable for digital communication of a kind of reinforcement.
The utility model is taked following technical scheme to realize: the anti-tampering cable for digital communication of a kind of reinforcement, and it comprises cable body, and described cable body comprises conductor, insulating barrier and oversheath, and described cable body inside is provided with many conductors; Described conductor outer wrapping one deck reinforced layer; Described reinforced layer and conductor form cable core jointly; Described cable body center is provided with plastic fiber; Described cable core closely extrudes a layer insulating outward; Described insulating barrier, between plastic fiber and cable core, gap portion is provided with packed layer; One deck polyester film lapping layer is extruded outside described insulating barrier; One deck damping oil reservoir is set outside described polyester film lapping layer; Described damping oil reservoir closely extrudes one deck oversheath outward.
Above-mentioned one strengthens anti-tampering cable for digital communication, and described conductor is any one in single copper wire, stranded bare copper wire or stranded tinned copper wire.
Above-mentioned one strengthens anti-tampering cable for digital communication, and the conductor that described cable body inside is arranged is even to outdiffusion centered by plastic fiber.
Above-mentioned one strengthens anti-tampering cable for digital communication, and described packed layer is made up of ceramic SiClx fire guard material.
Above-mentioned one strengthens anti-tampering cable for digital communication, and described insulating barrier is inorganic thin film, PVC coating or elastomeric material are made.

The utility model has following beneficial effect in sum: the utility model cable has the advantages such as the strong and long service life of reasonable in design, anti-tampering property, described oversheath adopts perfluoroethylene-propylene material to make, substantially increase the high and low temperature resistance of cable body, make cable in high temperature environments also can Long-Time Service, and electrical insulation capability is excellent, be not easy by chemicals attack, extend the useful life of cable.
Accompanying drawing explanation
Fig. 1 is the utility model cross-sectional structure schematic diagram;
Wherein: 1, cable body; 2, conductor; 3, reinforced layer; 4, plastic fiber; 5, packed layer; 6, insulating barrier; 7, polyester film lapping layer; 8, damping oil reservoir; 9, oversheath.
Embodiment
As shown in Figure 1, the anti-tampering cable for digital communication of a kind of reinforcement, it comprises cable body 1, and described cable body 1 comprises conductor 2, insulating barrier 6 and oversheath 9, and described cable body 1 inside is provided with many conductors 2; Described conductor 2 outer wrapping one deck reinforced layer 3; Described reinforced layer 3 and conductor 2 form cable core jointly; Described cable body 1 center is provided with plastic fiber 4; Described cable core closely extrudes a layer insulating 6 outward; Described insulating barrier 6, between plastic fiber 4 and cable core, gap portion is provided with packed layer 5; One deck polyester film lapping layer 7 is extruded outside described insulating barrier 6; One deck damping oil reservoir 8 is set outside described polyester film lapping layer 7; Described damping oil reservoir 8 is outer closely extrudes one deck oversheath 9.
The conductor 2 arranged in described cable body 1 is any one in single copper wire, stranded bare copper wire or stranded tinned copper wire, not only substantially increases the operating efficiency of cable, also makes its work more stable; One deck reinforced layer 3 of described conductor 2 outer wrapping can effectively protect conductor 2 not rupture by external force, substantially prolongs the useful life of conductor 2, can effectively protect conductor 2 not damage by high temperature, increase the heat-resisting ability of cable; Described packed layer 5 is ceramic SiClx fire guard, and it is under the condition of burning, becomes the refractory heat-insulating structure of ceramic-like solid refractory heat-insulating cover when meeting high temperature, and ceramic silicon materials, under burning condition, are met fire and then crusted, have good effect of heat insulation; Described plastic fiber 4 not only makes cable convenient when applying light source, and forms at least one plastic fiber 4 for subsequent use, improves the job stability of cable; The materials such as described insulating barrier 6 is inorganic thin film, PVC coating or rubber are made, thus make insulating barrier 6 have the characteristic such as excellent weather, resistance to ozone, heat-resisting, acid and alkali-resistance, resistance to steam, thus the stability of cable is improved, and insulating barrier 6 skin-friction coefficient is large, cable is when uninterrupted bending, also can not there is relative displacement in insulating barrier 6, thus ensure the normal output of electric property; Described polyester film lapping layer 7 improves stretch-proof performance and the anti-bending strength of cable, serves good electromagnetic shielding action, greatly reduces the signal degrade condition of cable when signal transmission; Described damping oil reservoir 8 has the effect of well buffering dispersion cable pressure, makes the outer wall of cable can quick-recovery soon when suffering external force; Described oversheath 9 adopts perfluoroethylene-propylene material to make, not only high temperature resistant, and also can not produce pernicious gas under burning condition, and have good compressive property.
The above is the utility model embodiment, therefore all equivalences done according to structure, feature and the principle described in the utility model application range change or modify, and are included in the utility model patent claim.
