Description
Technical field
The utility model relates to a kind of cable, and especially parallel outer conductor grid-type leaks cable.
Background technology
At present carrying out communicating in Mountain Tunnels and the occasion such as subway, mine, main what adopt is leaky coaxial cable.Leaky coaxial cable is a kind of radio-specific transmission " medium " of vast of heaven line, and forming the radio transmission channel of higher transmission quality, is the key component of radio communications system; The key of its design is the calculating of coupling loss, and the form of fluting then depends on the frequency range of used radio wave, but the calculating of current list of references to this parameter often adopts numerical algorithm, comparatively not accurate analytic solutions.In addition, leaky coaxial cable requires higher to manufacturing technology, and also will use a large amount of copper, cost is higher.Also have leaky coaxial cable to be conductor openings outside, once the standard that do not meet is difficult to make up after making, and during the transmission line of this cable as device port signal, easily suffer the electromagnetic interference of other equipment.
Utility model content
For solving the problem, the utility model provides one to manufacture simply, uses wave band wide, jamproof parallel outer conductor grid-type leakage cable, and concrete technical scheme is:
Parallel outer conductor grid-type leaks cable, is followed successively by inner wire, insulator, sheath from the inside to the outside; Also comprise outer conductor fixed bed, outer conductor and by-pass;
Described outer conductor fixed bed is located between insulator and sheath;
Described outer conductor annular is distributed in outer conductor fixed bed, and outer conductor is no less than three;
Described by-pass is established in the insulator, and is symmetrically distributed in the both sides of inner wire.
Described by-pass is steel wire rope.
Described outer conductor is aluminum conductor.
Outer conductor annular is distributed in outer conductor fixed bed, and outer conductor and inside conductor define parallel wire, and radiation signal is strong, and stable radiation is anti-interference.
Common leaky coaxial cable belongs to the transmission of single line ripple, and namely by solid conductor radiation, around it, set up alternating electromagnetic field, and complete diffusion by environment, its loss is very big.
Parallel outer conductor grid-type is leaked cable and is adopted multi-thread ripple to transmit, and namely by multiple conducting wires radiation, around it, sets up alternating electromagnetic field.Although multi-thread ripple transmission is also also set up alternating electromagnetic field around conductor, very weak induced current can only be caused to environment, so loss is very little.Simultaneously multi-thread ripple transmission continuous positive energy exchange in transmitting procedure, obtains when can realize the leakage field of radio communication along wire radial direction, maintains again the performance of radio signal along wire longitudinal direction low-loss transmission.
The outer conductor that parallel outer conductor grid-type leaks cable employing is the aluminum conductor that annular is distributed in outer conductor fixed bed, and inner wire adopts hollow copper pipe, saves the consumption of copper, reduces material cost.
Parallel outer conductor grid-type leaks cable not to be needed at outer conductor upper punch slotted eye, is suitable for wave band wide, and structure is simple, low cost of manufacture.
Leak in parallel outer conductor grid-type in the insulator of cable and with the addition of two steel wire ropes, enhance the tensile strength of whole leakage cable, decrease the diameter of inner wire, save material, reduce cost.
The parallel outer conductor grid-type that the utility model provides leaks the use that cable decreases copper, and structure is simple, and low cost of manufacture, tensile strength is high, stable radiation, and signal quality is good, anti-interference.
