Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of the novel resistant to bending radio frequency coaxial-cable of the embodiment of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, conductor center reinforcement, 2, inner wire skin, 3, insulating barrier, 4, outer conductor, 5, sheath.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Fig. 1 is the structural representation of the novel resistant to bending radio frequency coaxial-cable of the embodiment of the present invention; This radio frequency coaxial-cable comprises from inside to outside coaxial inner wire, insulating barrier 3, outer conductor 4 and the sheath 5 arranging successively, and described insulating barrier 3 is coated on inner wire, and described outer conductor 4 is coated on insulating barrier 3, and described sheath 5 is coated on outer conductor 4.
The inner wire of the novel resistant to bending radio frequency coaxial-cable that the present invention mentions has adopted the structure of combination inner wire, and to guarantee that radio frequency coaxial-cable has the resistant to bending characteristic of lightweight, this inner wire is made up of conductor center reinforcement 1 and inner wire skin 2.Wherein, conductor center reinforcement 1 has adopted aramid fiber to strengthen composite plastic bar, and this material has advantages of that density is little, quality is light, tensile strength is high, corrosion resistance is strong, excellent in durability, and its density is 1.8g/cm
3; Inner wire outer 2 adopts the copper pipe that thickness is 100um, to guarantee that this radio frequency coaxial-cable has excellent electric property.Because aramid fiber strengthens together with composite plastic bar can be attached on effectively with outer copper pipe, and its coefficient of linear expansion is mated with copper pipe, therefore can suppress the linear change of copper pipe in the time of variations in temperature, avoid or reduce because relative displacement occurs in connector end for aluminium matter outer conductor and copper inner wire and cause and be connected fault.
The insulating barrier 3 of the novel resistant to bending radio frequency coaxial-cable that the present invention proposes is made up of the physical blowing polyethylene of skin foam skin structure, these insulating barrier 3 materials can not only greatly improve insulation property and the return loss characteristic of cable, also can save the production cost of cable simultaneously.This novel resistance to bending radio frequency coaxial-cable outer conductor 4 selected the structure of smooth aluminum pipe, it is made up of the vertical bag welding of smooth aluminium strip; Adopt the outer conductor 4 of smooth aluminum pipe structure can guarantee that cable has excellent electric property, and guarantee that cable obtains very high tension and flattens intensity, harder than the wrinkled external conductor cable of same diameter; Can guarantee again both UV resistants of cable, again water is sealed completely simultaneously.This novel resistance to bending radio frequency coaxial-cable sheath 5 materials adopted polyvinyl chloride, it is coated on outer conductor by extrusion process.Novel resistant to bending radio frequency coaxial-cable in the present invention is compared with traditional plain edition radio frequency coaxial-cable, and its quality has reduced approximately 16%; Under operating frequency, the voltage standing wave ratio rate of change before and after this cable bend is only 0.9%, has embodied excellent bending resistance characteristic.
The present invention has disclosed a kind of novel resistant to bending radio frequency coaxial-cable, this radio frequency coaxial-cable production cost is low, lightweight, be easy to installation and maintenance, not only there is the excellent properties of smooth, the high resistance to compression of surfacing, high-tensile, also have advantages of that return loss is little, it is little to decay, heatproof characteristic is good.
The above; it is only the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; the variation that can expect without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range that claims were limited.
