Abstract
The utility model discloses an environment-friendly signal flexible cable with light weight, cold resistance, tensile properties, wire resistance and flame retardancy. The signal flexible cable includes a plurality of conductors, and the conductors are all covered with low density polyethylene insulating layers to form insulating wire cores. The insulation wires are twisted into a wire harness to form a cable core by taking a strength core as the center. The strength core is covered with a low density polyethylene protective layer. The cable core is sequentially covered with a polyester film tape, a non-woven fabric wrapping layer, and sheath layers made of halogen-free flame-retardant environment-friendly matte polyether polyurethane elastomer material. The signal flexible cable provided by the utility model is reasonable in structure and design, and is capable of supporting the use of vehicle controlling system instruments and electronic communication equipment. The signal flexible cable has the advantages of excellent flexibility, tensile properties, cold resistance, flame retardancy, and the like, thereby having good effect for practical application.

The kind of current existing electric wire cannot meet the use needs of vehicle-mounted TT&C system instrument and meter and electronics completely.
Utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of light-duty, cold-resistant, tension, wear-resisting, anti-flaming environment-friendly signal flexible cable, structural design advantages of simple, meets in narrow space for vehicle control syetem instrument and meter and electronics support the use.
The technical solution of the utility model is as follows:
Light-duty, cold-resistant, tension, wear-resisting, anti-flaming environment-friendly signal flexible cable; comprise many conductors; it is characterized in that: many described conductors are all coated with low density polyethylene (LDPE) insulating barrier outward and form insulated wire cores; insulated wire cores stranded bunchy centered by strengthening core forms cable core; strengthening core is coated with low density polyethylene (LDPE) protective layer, and cable core is coated with the restrictive coating of mylar tape, screen, nonwoven fabrics lapping layer, halogen-free flame-proof environmental protection cloudy surface EU elastomeric material outward successively.
Described light-duty, cold-resistant, tension, wear-resisting, anti-flaming environment-friendly signal flexible cable, is characterized in that: many described conductors all adopt the stranded formation of tinned wird that 32 filament diameters are 0.1mm.
Described light-duty, cold-resistant, tension, wear-resisting, anti-flaming environment-friendly signal flexible cable, is characterized in that: described strengthening core adopts the glass fiber bundle of 7 45/2 numbers to close formation.
Described light-duty, cold-resistant, tension, wear-resisting, anti-flaming environment-friendly signal flexible cable, is characterized in that: the thickness of described mylar tape is 0.03～0.05mm.
