Abstract
The utility model discloses an environment-friendly searching cable bundle which comprises a plurality of conductors. The plurality of conductors are respectively obtained through intertwisting a plurality of tin-coated copper wires. Hexafluoropropene-tetrafluoroethylene copolymers are respectively provided outside the plurality of conductors through extrusion shaping for forming insulating wire cores. The insulating wire cores are intertwisted for forming a cable core. Double shielding layers are coated outside the cable core. According to the double shielding layers, an aluminum-plastic composite film is wound for forming an inner layer. The winding coverage rate of the inner layer reaches 100%. Tin-coated copper wire is weaved outside the inner layer for forming an outer layer. The weaving density of the outer layer is no less than 80%. A sheath layer is provided outside the double shielding layers through extrusion shaping. The environment-friendly searching cable bundle has the following advantages: electromagnetic wave interference resistance, low-temperature resistance, wearing resistance, double-layer shielding, environment-friendly performance, high mounting flexibility, and high convenience.
Description
Technical field:
The utility model relates to electronic information technology or intelligent transport technology, relates in particular to a kind of environment-friendly type search cable bundle.
Background technology:
High speed development along with China's electronic technology, it requires also more and more higher to supporting electric wire, the kind of existing electric wire can't satisfy supporting needs fully, and its anti electromagnetic wave interference to cable product, high-low temperature resistant, high strength, resistance to wear, pliability, corrosion resistance, anti-mould and transmission quality are stable etc. has higher requirement.For vehicle-mounted, the boat-carrying electronic equipment is supporting that use has been proposed high requirement, there is no at present relevant cables both at home and abroad and can satisfy its specific (special) requirements, the YFW anti electromagnetic wave disturbs, low temperature resistant, wear-resisting, double shield environment-friendly type search cable bundle is the brand new special cable product that designs for its specific (special) requirements, it can not only satisfy vehicle-mounted, the supporting requirement of boat-carrying electronic equipment, also can satisfy the supporting of the electric equipment of other high new equipments and system electronics.
The utility model content:
In order to make up the prior art problem, the purpose of this utility model is to provide a kind of environment-friendly type search cable bundle, has that anti electromagnetic wave disturbs, low temperature resistant, wear-resisting, a double shield environment-friendly type, flexible for installation, characteristics easily.
The technical solution of the utility model is as follows:
Environment-friendly type search cable bundle, comprise several conductors, several conductors by the multiply tinned wird through restrainting stranded forming, it is characterized in that: the outer all extrusion moulding of described several conductors have the perfluoroethylene-propylene insulating barrier to consist of insulated wire cores, the stranded bunchy of insulated wire cores consists of cable core, cable core is coated with the double shield layer, the double shield layer adopts the wrapped formation internal layer of aluminum-plastic composite membrane, the wrapped coverage rate of internal layer reaches 100%, internal layer weaves tinned wird outward and consists of outer, outer field count is not less than 80%, and the outer extrusion moulding of double shield layer has restrictive coating.
Described environment-friendly type search cable bundle is characterized in that: also be designed with filled core in described cable core.
Described environment-friendly type search cable bundle is characterized in that: described restrictive coating cross section is for circular or oval, and adopting material is the polyether-type flame retardant thermoplastic polyurethane elastomer.
The utility model has the advantages that:
1, conductor is selected the tinned wird that solderability is good, resistance to corrosion is strong, adopts the method for many bundle strands to process, and not only softness, structure rounding, stable, guarantee communication quality.
2, insulation selects that dielectric strength is high, good high and low temperature, excellent chemical is stable, anticorrosive, creep is little, good flame resistance, anti-oxidant, anti-air stability is high, coefficient of friction is little and processability is good perfluoroethylene-propylene material, and this material satisfies the communication quality of high low temperature and adverse circumstances.
3, double shield, at first wrapped one deck intensity is high, good seal performance, protection against the tide, tear-proof, the plastic-aluminum combined film that good corrosion resistance and density are little (aluminium towards outside), adopt this metal and nonmetal laminated film, possessed double grading, add man-hour aluminium towards outside, the rate of putting up reaches more than 50%, coverage rate reaches 100%, more increased shield effectiveness, then woven the tinned wird that one deck resistance to corrosion is strong, non-oxidizability is excellent, count reaches more than 80%; Adopt this screened cable structure, guaranteed in the environment of strong-electromagnetic field, more can guarantee the reliability of transmitting.
4, sheath select be easy to process, mechanical strength and resistance to wear is high, ageing-resistant, outstanding pliability and low coefficient of friction, the polyether-type flame-retardant thermoplastic elastomer of the good environment-friendly type of hydrolytic resistance under endurance, mould proof, uvioresistant, high resiliency, good weatherability, fabulous toughness, low temperature, this material can satisfy under the environment of weather, salt fog, humidity or mechanical damage in cold, the product demand that keeps Essential Performance Requirements, the communication matter of assurance particular surroundings
5, several cables are formed according to requirements bunch of cables or be installed separately all can, flexible operation, convenience.If the cable bunchy uses, for intensity and the resistance to wear that increases cable, can put metal or non-metal knitted cover outside bunch of cables.
