Abstract
The utility model discloses a shied type steel-plastic composite belt for an optical cable. The shied type steel-plastic composite belt comprises a steel wire braid layer used as a base material layer, wherein the steel wire braid layer is formed by braiding a plurality of first steel wires used as the warp and a plurality of second steel wires used as the weft; the steel wire braid layer is pasted between a first plastic composite layer and a second plastic composite layer, both of which are formed by laminating a polyethylene film and a polyester film sequentially; the diameter of the first steel wire is 0.08-0.2 mm; the diameter of the second steel wire is 0.08-0.2 mm. The shield type steel-plastic composite belt for the optical cable, provided by the utility model, greatly reduces the consumption of metal, and reduces cost while the original product quality is maintained; moreover, the probability of damage in the plastic layer caused by bending, scratch and other factors is reduced, wear resistance, bending resistance and tear resistance of the composite belt are increased.
Description
Technical field
The utility model relates to a kind of optical cable composite band, relates in particular to a kind of optical cable shield type composite steel-plastic belt.
Background technology
At modern industry optical cable, extraordinary optical cable and cable communication production field, composite band is widely used, but how to use actual effect, excellent honest and clean material quite crucial, be enterprise soul, be that enterprise's stable development is competed effective guarantee with properties of product.
The at present domestic composite band of doing shielding, conduction, heat conduction, connection and insulation in electric wire, cable, electrical equipment, the integrated circuit that is used as is often selected single Copper Foil, following defective is arranged: the copper foil membrane of (1) domestic production, copper mostly through cold bundle, prolong pressure, high annealing forms, purity difference, became uneven, easily oxidation of surface, conduction, poor thermal conductivity; (2) density of copper is large, causes the quality of product overweight, has increased production and cost of transportation; (3) China's copper shortage of resources, annual a large amount of imports, the cost height of relying on.
Summary of the invention
The utility model provides a kind of optical cable shield type composite steel-plastic belt, and this optical cable greatly reduces the use amount of metal with the shield type composite steel-plastic belt, when having kept original properties of product, has reduced cost; Secondly, also reduced because the probability that plastic layer damages occurs the factors such as bending, scratch, improved the composite band wearability, folding resistance and tear resistance.
For achieving the above object, the technical solution adopted in the utility model is: a kind of optical cable shield type composite steel-plastic belt, comprise a steel wire braid as substrate layer, this steel wire braid is formed by some the first steel wire and some the second braided steel wires as parallel as warp, this steel wire braid is covered between the first plastics composite bed and the second plastics composite bed by adhesive-layer, and this first plastics composite bed and the second plastics composite bed stack gradually composition by polyethylene film and polyester film.
Further improved technical scheme is as follows in the technique scheme:
1. in the such scheme, described the first steel wire diameter is 0.08～0.2mm, and described the second steel wire diameter is 0.08～0.2mm.
2. in the such scheme, described the first steel wire density as warp is 190210/cm, and described the second steel wire density as parallel is 180220/cm.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1. the utility model optical cable composite band, its plastics composite bed stacks gradually composition by polyethylene film and polyester film, greatly reduce since bending, scratch etc. because of rope, the probability that plastic layer damages occurs, improved the composite band wearability, folding resistance and tear resistance have guaranteed the bulk strength of composite band.
2. the utility model optical cable composite band, its reasonable in design, simple, it has reduced the cable footpath as far as possible, guarantees that to adapt to instructions for use the structure of optical cable and quality are all unaffected.
