Abstract
A radiation-proof coaxial cable comprises an inner conductor, an insulation layer, an outer conductor and an outer sheath; the outer conductor consists of an inner copper foil layer, a braided layer and an outer copper foil layer; the inner conductor, the insulation layer, the inner copper foil layer, the braided layer, the outer copper foil layer and the outer sheath are arranged from the inside out along the radial direction in sequence; and a resin bonding layer is coated between the inner conductor and the insulation layer, and is bonded between the inner conductor and the insulation layer. The insulation layer and the inner copper foil layer of the outer conductor respectively adopt a self-bonding structure. The outer foil layer of the outer conductor adopts a structure formed by a PE layer bonded with pure copper foil. Because the outer conductor in the radiation-proof coaxial cable consists of the inner copper foil layer, the braided layer and the outer copper foil layer, a layer of structure is added; compared with the common prior coaxial cable, the cable solves the outward radiation interference of the coaxial cable, and at the same time, the outside radiation interference on the cable is avoided, thereby enhancing the use effect of the cable.
Description
(1) technical field
The utility model relates to a kind of radiation proof coaxial cable.
(2) background technology
Coaxial cable is the main medium of transmitting radio frequency signal, and shielding character is a parameter weighing the coaxial cable antijamming capability, also is an important parameter weighing the coaxial cable anti-leak.If cable shield is bad, transmission signals not only can be subjected to crosstalking of external clutter, influences signal quality, also can let out and disturb other signals, has a strong impact on the normal use of product.The outer conductor of coaxial cable directly influences the shielding character of product, existing common coaxial cable, outer conductor only is made up of single aluminium foil layer and single braid, shielding resistance height, shield effectiveness is relatively poor relatively, the easily outside radiated interference of product, simultaneously, product itself is vulnerable to the radiated interference of outer bound pair self again, influences the product result of use; In addition, there is not adhesive structure between existing coaxial cable insulating barrier and the inner wire, the insulating barrier mechanical strength is low simultaneously, be easy to destroy, special in semi-finished product circulation process or finished product easily cause inner wire and insulating barrier relative displacement when laying and form the gap that can enter moisture or moisture, and make the inner wire surface oxidation, and influence transmission performance, shorten cable useful life.
(3) summary of the invention
The technical problems to be solved in the utility model provides that a kind of radiation proof is effective, transmission performance is stable, the radiation proof coaxial cable of long service life.
For this reason, the utility model is taked following technical scheme:
A kind of radiation proof coaxial cable, include inner wire, insulating barrier, outer conductor, oversheath, described outer conductor is made up of interior copper foil layer, braid, outer copper foil layer, described inner wire, insulating barrier, interior copper foil layer, braid, outer copper foil layer, oversheath radially are provided with successively from inside to outside, are laminated with resin bonded laminate between described inner wire and the insulating barrier.
Described resin bonded laminate is bonded between inner wire and the insulating barrier.
The interior copper foil layer of described insulating barrier and outer conductor adopts the self-adhesion structure.
What the outer copper foil layer of described outer conductor adopted is the glutinous structure that forms of covering of PF layer and pure copper foil.
The utility model has the advantages that: 1, outer conductor is made up of interior copper foil layer, braid, outer copper foil layer, increased one deck structure, existing relatively common coaxial cable, this product has solved the outside radiated interference of coaxial cable, simultaneously, avoid the radiated interference of outer bound pair this product self again, improved the product result of use; 2, between inner wire and insulating barrier, be laminated with resin bonded laminate, this resin bonded laminate not only is bonded as one with inner wire, and also be bonded as one with insulating barrier, thereby make cable in semi-finished product circulation process or finished product lay Shi Buhui and make when being subjected to external force extruding or transmission between inner wire and the insulating barrier and produce relative displacement and form the gap that can enter moisture or water, improved the water resistance of cable, make inner wire can not produce oxidative phenomena, improve the stability of its transmission performance, and useful life can be longer; The concentricity of cable insulation is stable simultaneously, helps the control of jitter; 3, the structure of the interior copper foil layer of outer conductor is that copper is moulded structure, and the layer of moulding of insulating barrier and Copper Foil is subjected to the heat energy tight bond together, forms stable concentricity structure, avoids the signal bias and the distortion of cable; 4, the outer copper foil layer structure of outer conductor also is that copper is moulded structure, and Copper Foil is wherein moulded the braid that layer plays with the second layer isolation effect non-conductive, mutually insulated.Three-decker by outer conductor produces two outer conductor screens, but first screen ground connection, be the video signal transmission loop " "; 5, the outer copper foil layer of outer conductor is second screen, owing to adopt copper foil structure to make outer conductor resistance low, the interference induced electromotive force that can effectively the interior external world be covered on the layer has been got rid of outside the transmission of video signals loop, realizes the radiation proof interference effect; 6, shielding property is better than the effect of aluminium foil+braiding; Effectively improve the video transmission quality of coaxial cable, realized remote, noiseless video transmission; Effectively enlarged the video transmission scope of coaxial cable; 7, lower than four shield effectiveness prices; 8, the Copper Foil of Cai Yonging is that plastic-aluminum and copper meet and forms, and is flexible; 9, simplify the difficulty of design and construction of engineering, reduced anti-interference engineering cost; 10, simple, the compact conformation of production technology, low cost of manufacture, result of use are good.
(4) description of drawings
Fig. 1 is the utility model structure cross-sectional schematic;
Wherein, 1-inner wire, 2-resin bonded laminate, copper foil layer in the 3-insulating barrier, 4-, 5-braid, the outer copper foil layer of 6-, 7-oversheath.
(5) specific embodiment
With reference to accompanying drawing 1, a kind of radiation proof coaxial cable, include inner wire 1, insulating barrier 3, outer conductor, oversheath 7, described outer conductor is made up of interior copper foil layer 4, braid 5, outer copper foil layer 6, described inner wire, insulating barrier, interior copper foil layer, braid, outer copper foil layer, oversheath radially are provided with successively from inside to outside, are laminated with resin bonded laminate 2 between described inner wire and the insulating barrier.Described resin bonded laminate is bonded between inner wire and the insulating barrier.The interior copper foil layer of described insulating barrier and outer conductor adopts the self-adhesion structure.What the outer copper foil layer of described outer conductor adopted is the glutinous structure that forms of covering of PE layer and pure copper foil.
