Abstract
The utility model relates to an environment-friendly flame-retardant computer shield cable. The cable comprises wires. The outer surface of each wire is coated with a thermoplastic halogen-free flame-retardant polyolefin insulating layer. Each thermoplastic halogen-free flame-retardant polyolefin insulating layer is wrapped by a wrapping tape insulating layer. Each wrapping tape insulating layer is coated with a flexible copper-aluminum composite tap wrapping sub shield layer. The halogen-free flame-retardant filling ropes are wound around the flexible copper-aluminum composite tap wrapping sub shield layers and fill the space outside the copper-aluminum composite tap wrapping sub shield layers. The halogen-free flame-retardant filling ropes are wrapped by a flexible copper-aluminum composite tap wrapping shield layer. The flexible copper-aluminum composite tap wrapping shield layer is coated with an oxygen-free copper wire woven shield layer. The oxygen-free copper wire woven shield layer is coated with a halogen-free flame-retardant tape wrapping insulating layer. A sheath is formed on the outside of the halogen-free flame-retardant tape wrapping insulating layer through extrusion. The environment-friendly flame-retardant computer shield cable provided by the utility model has the advantages of reasonable structure design, low cost and excellent shield performance. The insulating layer and the sheath of the cable are made of thermoplastic halogen-free flame-retardant polyolefin, so that the cable has good flame-retardant properties and physical and mechanical properties.
Description
Technical field
The utility model relates to cable technology field, specifically a kind of environmental protection flame retardant computer shielded cable.
Background technology
Along with popularizing of network technology, the use of computer cable is more and more, along with scientific and technological development, the electromagnetic field in space is more and more intensive, and people require more and more higher to the isolation electromagnetic performance of computer cable, in addition, because the use amount of cable is increasing, cable rubbish or the pollution being produced by cable more and more cause people's attention, need a kind of high comprehensive performance on market, safety and environmental protection, and the computer cable of shield electromagnetic interference preferably.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of environmental protection flame retardant computer shielded cable.
The utility model solves its technical problem and realizes by the following technical solutions:
A kind of environmental protection flame retardant computer shielded cable, comprises wire, and described wire is 1 to 12 group, and every group of wire outer surface is all enclosed with thermoplastic halogen-free flame retarding polyolefin insulation layer; Described thermoplastic halogen-free flame retarding polyolefin insulation layer is all surrounded with band separator outward; Described band separator is all enclosed with the wrapped sub-shield of soft copper aluminum composite belt outward, is provided with the stranded soft drainage thread of copper free wire between band separator and the wrapped sub-shield of soft copper aluminum composite belt No. one; The peripheral winding of the wrapped sub-shield of described soft copper aluminum composite belt is filled with halogen-free flameproof gasket for packing; Described halogen-free flameproof gasket for packing periphery is surrounded with soft copper aluminum composite belt lapped shielding layer, is provided with the stranded soft drainage thread of copper free wire between halogen-free flameproof gasket for packing and soft copper aluminum composite belt lapped shielding layer No. two; Described soft copper aluminum composite belt lapped shielding layer peripheral hardware has anaerobic proof copper-wire braided screen; Described copper free wire woven shield peripheral hardware has the wrapped separator of Halogen inhibiting tape; The wrapped separator of described halogen-free flameproof band is extruded with oversheath outward.
Described wire is that multiply annealed copper skein silk closes the copper cash forming, and the copper wire combination property after annealing further promotes, and the sectional area of wire is 0.5～2.5mm
2.
Described drainage thread area of section is not less than 1/4th of conductor cross-section area.
Described oversheath adopts thermoplastic halogen-free flame retarding polyolefine material to make.
The beneficial effects of the utility model are: the utility model reasonable in design, with low cost, shielding properties is splendid, the insulating barrier of cable and oversheath adopt thermoplastic halogen-free flame retarding polyolefin, effectively improve the serviceability of product, make cable there is good anti-flammability, physical and mechanical properties, electrical insulation capability, ensured good safety and the reliability of cable.
The advantage that the utility model also has is:
(1) there is the characteristic that does not discharge hydracid and certainly put out from fire, can reduce in a large number the generation of poisonous corrosive discharge and smog;
