Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the present invention is further described.Following example are only used for clearly illustrating technical scheme, and can not limit the scope of the invention with this.
As shown in figs 1 to 6, a kind of cable, described cable includes inner wire 1 and is wrapped in the teflon insulation layer 2 of inner wire 1, outer conductor layer 3 and sheath 4 successively;Described inner wire 1 is formed by silver-coated copper wire is stranded;Described cable is provided with bending region, is provided with axially disposed multiple bend resistance sheet metals 5 in the sheath 4 in described bending region, and described bend resistance sheet metal 5 is interrupted setting vertically;The width of described bend resistance sheet metal 5 progressively reduces to both sides from the middle part in bending region, and described bend resistance sheet metal 5 is copper sheet, and it is internal that described bend resistance sheet metal 5 embeds sheath 4;Sheath 4 is outside is provided with cable anti false film.
Described sheath 4 is the perfluoroethylene-propylene pipe box being filled with nylon or glass fibre;Described insulating barrier is the perfluoroethylene-propylene layer being filled with nylon or glass fibre.
Institute's inner wire 1 is formed by 7 silver-coated copper wires are stranded, described inner wire 1 overall diameter size 0.24 ~ 0.51mm;Described outer conductor layer 3 is silver-coated copper wire braid, described outer conductor layer 3 overall diameter size 0.92 ~ 1.95mm.
The communication efficiency of wire can be greatly improved by arranging silver coating in the outside of copper conductor in use, Kelvin effect based on signal transmission, preferable for electric conductivity silver layer is arranged on outermost end and can well take into account cost and electric conductivity;Polytetrafluoroethylmaterial material insulating barrier can improve insulation effect.By being embedded in bend resistance sheet metal 5 at the sheath 4 in bending region, at cable bending region bending when, when being folded into certain angle, the rigidity of bend resistance sheet metal 5 can suppress further to bend, owing to the width of bend resistance sheet metal 5 progressively reduces to both sides from the middle part in bending region, the bending angle at middle part is less, and the bending angle of both sides is bigger, the bending radius of cable folding can be improved, reduce the excessive damage that wire rod is brought of unit length bending angle.
Common cable, when bending, easily forms the bending angle of wide-angle in shorter length, and in the middle part of it, bending angle is maximum, takes second place in both sides.The structure of the application just bending region with common cable compensates, longer length completes same bending angle, reduce the excessive damage that wire rod is brought of unit length bending angle and can improve the bending radius of cable folding, reduce the excessive damage that wire rod is brought of unit length bending angle.
As optimization, sheath 4 is outside is additionally provided with cable anti false film, described cable anti false film includes the first printing opacity anti false film 51, Protective film 52, selective membrane 53 and the second printing opacity anti false film 54 that overlapping combinations uses each other, described first printing opacity anti false film 51 is provided with first two-dimension code anti-counterfeit Figure 55, described second printing opacity anti false film 54 is provided with second two-dimension code anti-counterfeit Figure 56, described Protective film 52 is white films, and described selective membrane 53 is the white films offering selection window 64;Described first printing opacity anti false film 51 is with under Protective film 52 overlap condition, and first two-dimension code anti-counterfeit Figure 55 is visual;Described second printing opacity anti false film 54 is successively with under selective membrane 53 and Protective film 52 overlap condition, and second two-dimension code anti-counterfeit Figure 56 is visual;Under described first printing opacity anti false film 51 and the second printing opacity anti false film 54 film overlap condition, first two-dimension code anti-counterfeit Figure 55 and second two-dimension code anti-counterfeit Figure 56 overlapping combinations form the false proof Figure 57 of combined two-dimension code;Described second printing opacity anti false film 54 is successively with under selective membrane 53 and the first printing opacity anti false film 51 overlap condition, and combination is formed and selects two-dimension code anti-counterfeit Figure 58.
First printing opacity anti false film 51, Protective film 52, selective membrane 53 and the second printing opacity anti false film 54 set gradually, and by adhesive linkage 59 temporary bond between adjacent film;
Described first printing opacity anti false film 51 and the second printing opacity anti false film 54 upper end upwardly extend and are formed and the annular connecting portion 60 of cable socket, and the opening part of described annular connecting portion 60 forms fixed bonding portion 61 by hot stamping.
Described first printing opacity anti false film 51 and the second printing opacity anti false film 54 bottom have been provided with limit film 62;The lower end of described anti false film and Protective film 52 is downwardly extending ring seal structure 63.
When false proof, the first printing opacity anti false film 51, Protective film 52, selective membrane 53 and the second printing opacity anti false film 54 set gradually, and by adhesive linkage 59 temporary bond between adjacent film;Now can read first two-dimension code anti-counterfeit Figure 55 by the lap fit of the first printing opacity anti false film 51 with Protective film 52 at the visual angle, side of the first printing opacity anti false film 51;Can be overlapping with selective membrane 53 and Protective film 52 successively by the second printing opacity anti false film 54 at the second visual angle, printing opacity anti false film 54 side, read second two-dimension code anti-counterfeit Figure 56;
First printing opacity anti false film 51 is uncovered by playing limit film 62, again Protective film 52 is uncovered, then the first printing opacity anti false film 51, selective membrane 53 and the second printing opacity anti false film 54 is overlapping, at the second printing opacity anti false film 54 side-looking angle, the selection window 64 of selective membrane 53 have chosen the figure on part the first two-dimension code anti-counterfeit Figure 55, and selected figure overlaps with second two-dimension code anti-counterfeit Figure 56 to be formed again and selects two-dimension code anti-counterfeit Figure 58.
Protective film 52 and selective membrane 53 are removed between the first printing opacity anti false film 51 and the second printing opacity anti false film 54, first printing opacity anti false film 51 and the second printing opacity anti false film 54 lap fit, first two-dimension code anti-counterfeit Figure 55 and second two-dimension code anti-counterfeit Figure 56 overlapping combinations are formed the false proof Figure 57 of combined two-dimension code.
So the storage of cable anti false film and four groups of anti-counterfeiting information, expand anti-counterfeiting information amount, adds forgery cost and difficulty.Annular connecting portion 60 is beneficial to cable anti false film assembly and is connected with cable fixing, and certain fixing and positioning action can play in fixed bonding portion 61, is possible to prevent its position sideslip during the first printing opacity anti false film 51 is uncovered and put back to;Selective membrane 53 can be completed processing in a white films by Protective film 52 by ring seal structure 63, it is simple to assemble processing.
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, front lower without departing from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention.
