Abstract
A radio frequency coaxial cable and optical fiber composite cable with a novel structure is characterized by sequentially comprising an optical fiber (1), an inner conductor (2) of a radio frequency coaxial cable, an insulating layer (3) of the radio frequency coaxial cable, an outer conductor (4) of the radio frequency coaxial cable and an outer sheath layer (5) from inside to outside. The radio frequency coaxial cable and optical fiber composite cable with the novel structure is applicable to environments, which have requirements incapable of being met by single use of radio frequency coaxial cables or optical cables, such as indoor wiring of mobile communication networks. Besides, the radio frequency coaxial cable and optical fiber composite cable not only meets current wiring requirements, but also lays a foundation for future complete coverage and comprehensive wiring of the communication networks.
Description
Technical field
Patent of the present invention relates to a kind of radio frequency coaxial-cable and hybrid optical fiber cable of new structure, the invention 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 all are 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, and it is little to decay, and 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, want so that mobile communications network covers more comprehensively, if just transmission medium overcomes complicated and diversified environment, how to realize that the comprehensive wiring of complicated various environment to guarantee the quality of signal of communication, has proposed challenge to mobile communication cable production firm.
Summary of the invention
Patent of the present invention 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 the two advantage, adopting complementary idea that the shortcoming of the two is 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.
The radio frequency coaxial-cable of Patent design new structure of the present invention and hybrid optical fiber cable, satisfy the index of optical cable and cable, production cost, complex process degree and the engineering complexity of the type product had both been greatly reduced, can solve again the in use effect such as protection against rodents, anti-ant of optical fiber, 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 at present demand of wiring, can for later communication network covers comprehensive wiring comprehensively, carry out technological reserve again.
Description of drawings
Fig. 1 be the radio frequency coaxial-cable of patent new structure of the present invention and hybrid optical fiber cable partly cut open schematic diagram.
Embodiment
As shown in Figure 1, the radio frequency coaxial-cable of new structure of the present invention 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 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.Adopt the mode of welding, embossing only to be coated on insulation foaming layer surface.
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 cable inner sheath surface.
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, coat an outer conductor through welding, embossing mode in insulation foaming layer outside again, 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, coat an outer conductor through welding, embossing mode in insulation foaming layer outside, finally through the sheath moulding.
Example recited above only is that the general execution mode to patent of the present invention is described, and technology contents and manufacture method that the present invention asks for protection all are documented in claims.
