Abstract
The utility model discloses a shielding cladding belt for an optical cable. The shielding cladding belt comprises a copper wire woven layer as a base layer, wherein the copper wire woven layer is formed by weaving a plurality of first copper wires as warps and a plurality of second copper wires as wefts; the copper wire woven layer is pasted between a plastic composite layer and an aluminum foil layer through an adhesive layer; the plastic composite layer is formed by sequentially laminating polyethylene films and polypropylene films; the polyethylene films in the plastic composite layer and the copper wire weaving layer are fixed in an adhesive manner; the density of the first copper as the warps is 190-210/cm; and the density of the second copper as the wefts is 190-210/cm. The shielding cladding belt for the optical cable provided by the utility model greatly reduces usage amount of metal, maintains the original performance of a product while reducing the cost, in addition, reduces the probability of damage to the plastic layer due to the factors of bending, rubbing and the like, and improves the abrasion resistance, folding resistance and tear resistance of the composite belt.
Description
Technical field
The utility model relates to a kind of optical cable composite band, relates in particular to a kind of optical cable and coats band with shielding.
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 to coat band with shielding, and this optical cable coats the use amount that band greatly reduces metal with shielding, 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 coats band with shielding, comprise a proof copper-wire braided layer as substrate layer, this proof copper-wire braided layer is formed by some the first copper wire and some the second proof copper-wire braideds as parallel as warp, this proof copper-wire braided layer is covered between plastics composite bed and the aluminium foil layer by adhesive-layer, and this plastics composite bed is stacked gradually by polyethylene film and polypropylene screen and forms.
Further improved technical scheme is as follows in the technique scheme:
1. in the such scheme, polyethylene film and proof copper-wire braided layer in the described plastics composite bed are adhesively fixed.
2. in the such scheme, the Thickness Ratio in the described plastics composite bed between polyethylene film and the polypropylene screen is 1:0.5～2.5.
3. in the such scheme, described the first copper wire density as warp is 190 210/cm, and described the second copper wire density as parallel is 180 220/cm.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1. the utility model optical cable coats band with shielding, its reasonable in design, simple has reduced cost, and the product of using before comparing greatly reduces the use amount of metal, and kept original properties of product, therefore increased more economic benefit and social benefit widely.
2. the utility model optical cable coats band with shielding, 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.
