Detailed description of the invention
As shown in Figure 1 and Figure 2, a kind of anti-shielding protection against the tide data cable, including conductor 2, insulating barrier 9, armor 10,
Compound copper-plastics band screen layer 11, reinforcing braid 12, toughening layer 13, seamless wrinkle are knitted set 14, graphite linings 15 and protect outward
Set 1；Present embodiment is provided with three conductors 2 in cable altogether, and the cross section of every conductor 2 is circular configuration, often
Root conductor 2 is combined by several wire core 3, and described core 3 is that the copper cash of bare copper wire or tin plated materials is strengthened with conduct
The carbon fibre material of structure is stranded to be formed, and several wire core 3 can be the bare copper wire or tin-coated copper that specification is identical or specification is different
The stranded composition of line, strand copper wire puts in order and lay twists together by certain, has reformed into the conductor being relatively large in diameter,
It is more soft that this stranded major diameter conductor props up copper cash than the list of same diameter size, and the cable bend performance made is good,
Do not allow easily broken when waving test, can preferably reach requirement for some cables that softness is required, and its signal transmits
The most more stable.Being provided with three packings 4 that block water in every conductor 2, the packing 4 that blocks water uses nylon material system
Make, in the present embodiment, use nylon PA66 material to make.Three packings 4 that block water become flabellum shape in conductor 2
It is uniformly distributed, and core 3 even partition constituting conductor 2 is become three parts；In the present embodiment, three conductors 2 is straight
Footpath is 3 millimeters, and the packing 4 that blocks water can effectively stop the phenomenons such as cable inner the occurrence of wetness, it is to avoid cable internal cause is subject to
Tide and break down；And conductor 2 is separated into three non-interfering separate space, each compartment by three packings 4 that block water
Inside being provided with some cores 3, so that not havinging situation about interfering when core 3 works, and being provided with in cable
Three conductors 2, can improve the current capacity of cable, and the transmission also making signal is more quick；Described conductor 2 is between any two
Connect fixing by PVC plastic connecting rod 5, be possible not only to improve the stability of cable main body structure, and described PVC plastic
Material connecting rod 5 mutually supports, and being effectively protected conductor 2 will not be the most damaged, thus improves the service life of cable；
Center clearance region between three conductors 2 is provided with some light unit 6；Described smooth unit 6 is single-mode fiber or many
Mode fiber, not only makes the propagation information rate of cable faster, and is not readily susceptible to the interference in the external world so that making of cable
With more reliable and more stable, and the capacity of Information Communication is bigger；Gap portion between described conductor 2 and light unit 6 is filled with
Filler 7, described filler 7 is non-wet materials, and such as polypropylene mesh split fibre material, filler 7 can be effective
Protection light unit 6 will not improve twisting resistance and the crushing resistance of cable because being occurred losing by external force bending, be effectively protected
Cable.
Being extruded with insulating barrier 9 outside conductor 2, its insulating barrier 9 is that the materials such as inorganic thin film, PVC coating or rubber are made,
Present embodiment uses inorganic thin film to make insulating barrier 9, after arranging insulating barrier 9, can significantly improve the insulation effect of cable.
Gap portion between described insulating barrier 9 and conductor 2 is provided with elastic packing 8, and described elastic packing 8 uses elasticity
Elastomeric material makes, and its material itself has good elastic performance, when cable is bent by external force, protects to a certain extent
Card cable has bending and the ability of non-reversible deformation does not occur, it is ensured that cable can use in the environment of alternating bending, carries
The high environmental suitability of cable；In the outside of insulating barrier 9, extrude armor 10, compound copper-plastics band screen the most successively
Cover layer 11 and reinforcing braid 12；Its armor 10 is that steel band, steel wire, aluminium strip or aluminium tube material are made, this embodiment party
In formula, the steel wire parcel that its armor 10 uses diameter to be less than 0.2 millimeter forms；Steel wire armor layer has high permeability,
There is good Magnetic Shielding Effectiveness, may be used for anti-glitch, and armored cable directly buried installation can be made to avoid poling and enhancing
The tensile strength of cable and interference free performance.Compound copper-plastics band screen layer 11 uses the Copper Foil that plating film is contained on multiply surface
Silk is formed, and covers on armor 10 surface with list structure, is effectively increased service life of cable and water-fast and resistance to
Weathering aging；Reinforcing braid 12 is made up of vinal material or pet material, energy
It is effectively improved the resistance to bend(ing) of cable, hot strength and reliability so that it is using effect is more outstanding；At reinforcing braid
Arranging toughening layer 13 outside 12, toughening layer 13 uses the nylon nonwoven fabrics material with excellent toughness to make, toughening layer 13 with
Reinforcing braid 12 tight；Outside toughening layer 13, it is disposed with seamless wrinkle knit set 14, graphite linings 15 and protect outward
Set 1, it is seamless, and wrinkle knits that set 14 is made for glass fibre material material, and oversheath 1 is polyvinyl chloride material material, graphite
The graphite powder filling that layer 15 is less than 0.05 millimeter for diameter particle forms, and graphite linings 15 can be exhausted as measuring oversheath 1
External electrode during edge, also can promote the insulating properties of cable, and protection cable is not easily susceptible to corrode simultaneously, thus improves cable
Service life.The toughening layer 13 arranged in cable cooperates with reinforcing braid 12, makes cable have more more effective
Fatigue durability and mar proof, even if cable is by bigger shock, it is possible to quickly restore to the original state, improve the toughness of cable,
Play the effect of protection cable；Oversheath 1 and seamless wrinkle that ecto-entad is arranged are knitted set 14 and are not only acted as protection cable not
Injured effect, and the seamless wrinkle made of glass fibre material knits set 14 and can play the effects of moisture-resisting water-proof, it is to avoid water
Dividing invades in cable main body, causes cable to break down because making moist；Set oversheath 1 can protect cable not because of mistake
Cable inner is damaged by degree stretching or corrosion so that it is is adapted to the most severe natural environment, also improves cable
Job stability.
The above is the embodiment of the present invention, thus all according to structure, feature and the principle described in the present patent application scope done etc.
Effect change or modification, in the range of being all included in present patent application.
