The novel structure radio frequency coaxial cable and optical fiber composite cable is suitable to be used in indoor wiring of mobile communication network and other environments where single radio frequency coaxial cables or optical fibers cannot be used. The cable not only realizes requirement of wiring at present, but also lays foundations for communication network complete coverage comprehensive wiring in future.
Description
Technical field
The utility model patent relates to a kind of radio frequency coaxial-cable and hybrid optical fiber cable of new structure, and the utility model belongs to communications cable product in the communication transfer field, can be used for the transmission of the signal of communication of multiple environment.
Background technology
In field of communication transmission, radio frequency coaxial-cable and optical cable are all important transmission signal vectors, are widely used in the comprehensive wiring of mobile communications network.
Because radio frequency coaxial-cable and optical cable have it separately, as: the radio frequency coaxial-cable environmental resistance is good, and quality of connection is stable, need not the electrooptical device through complexity, but its decay is large, and production cost is high; The optical cable production cost is low, decays little, can zoom out to lay, but its environmental resistance is poor, is not easy to bending.Consider the complicated variety of comprehensive wiring environment, single use radio frequency coaxial-cable or optical cable all can be subject to the restriction of construction environment and applied environment, make mobile communications network cover more comprehensively, if just transmission medium overcomes complicated and diversified environment, how to realize the comprehensive wiring of complicated various environment to guarantee the quality of signal of communication, production firm has proposed challenge to the mobile communication cable.
Summary of the invention
The utility model patent is on the technique basis of existing radio frequency coaxial-cable and optical cable, and a kind of radio frequency coaxial-cable and hybrid optical fiber cable of new structure is provided.This mixes cable and adopts brand-new design concept and new production technology, greatly reduce production cost, complex process degree and the engineering complexity of the type product, comprehensive advantage both, adopting complementary idea that shortcoming is both improved, is the change to the revolution of existing mobile communication signal transmission medium.
The radio frequency coaxial-cable of new structure and hybrid optical fiber cable are followed successively by optical fiber 1 from inside to outside, inner conductor of radio frequency coaxial cable 2, RF coaxial cable insulation cable layer 3, radio frequency coaxial-cable outer conductor 4, external sheath layer 5.
Described optical fiber 1 is the optical fiber after processing through the simple process such as painted, that cover is moulded.
Described inner conductor of radio frequency coaxial cable 2 is smooth seamless copper pipe or copper cladding aluminium pipe.
Described RF coaxial cable insulation cable layer 3 is a certain proportion of high and low density polyethylene mix insulation material.
Described radio frequency coaxial-cable outer conductor 4 is pure copper strips.
Described external sheath layer 5 is low smoke halogen-free flame-retardant polyolefin or Polyethylene insulated cable protective cover material.
radio frequency coaxial-cable and the hybrid optical fiber cable of the utility model Patent design new structure, satisfy the index of optical cable and cable, both greatly reduced the production cost of the type product, complex process degree and engineering complexity, can solve again in use protection against rodents of optical fiber, the effects such as anti-ant, not impaired to guarantee signal of communication, being applicable to the house wiring etc. of mobile communications network can not single use radio frequency coaxial-cable or the environment of optical cable, both can realize the demand of wiring at present, can cover comprehensive wiring for later communication network again comprehensively, carry out technological reserve.
Description of drawings
Fig. 1 be the radio frequency coaxial-cable of the utility model patent new structure and hybrid optical fiber cable partly cut open schematic diagram.
Embodiment
As shown in Figure 1, the radio frequency coaxial-cable of new structure described in the utility model and hybrid optical fiber cable are followed successively by optical fiber 1 from inside to outside, inner conductor of radio frequency coaxial cable 2, RF coaxial cable insulation cable layer 3, radio frequency coaxial-cable outer conductor 4, external sheath layer 5.
Described optical fiber 1 is for meeting the monomode fiber of GB/T 9771.1-2008 standard, penetrates in the hollow inner wire of radio frequency coaxial-cable after the simple process such as painted, that cover is moulded is processed.
Described inner conductor of radio frequency coaxial cable 2 is the smooth copper cladding aluminium pipe that meets the smooth seamless copper pipe of GB/T 19849 or meet GB/T4437.1-2000.
Described RF coaxial cable insulation cable layer 3 is according to concrete X:X: the high and low density polyethylene mix insulation material of ratio should meet the requirement of YD/T 897.1-1996.Adopt the physical blowing mode closely to stick to the inner wire surface.
Described radio frequency coaxial-cable outer conductor 4 is for meeting the pure copper strips of GB/T 11091 standards.It is surperficial that the mode of employing welding, embossing only is coated on the insulation foaming layer.
Described external sheath layer 5 is the low-smoke halogen-free flame-retardant polyolefin cable protective cover material, should meet YD/T 1113-2001 or Polyethylene insulated cable protective cover material, should meet GB/T 15065-1994.Adopt crowded tubular type to be extruded in equably the cable inner sheath surperficial.
Radio frequency coaxial-cable and the hybrid optical fiber cable of this patent design new structure, to penetrate in the hollow copper tubing inner wire of radio frequency coaxial-cable through optical fiber painted, that overlap simple process processing such as moulding, through the physical blowing mode at inner conductor of radio frequency coaxial cable surface adhesion one insulation foaming layer, again through welding, embossing mode at the outside outer conductor that coats of insulation foaming layer, the sheath moulding, radio frequency coaxial-cable and the hybrid optical fiber cable of formation new structure.Can be according to actual operation requirements, the multi-core fiber of varying number is penetrated in the hollow copper tubing or copper cladding aluminium pipe inner wire of radio frequency coaxial-cable, then through the physical blowing mode at inner conductor of radio frequency coaxial cable surface attachment one insulation foaming layer, through welding, embossing mode at the outside outer conductor that coats of insulation foaming layer, finally through the sheath moulding.
Example recited above is only that the general execution mode to the utility model patent is described, and technology contents and manufacture method that the utility model is asked for protection all are documented in claims.
