The utility model discloses a realize above-mentioned purpose, the technical scheme who adopts is: the utility model provides a 2 to 5 core self-filling flexible cable which characterized in that: comprises a pair-twisted wire group unit, a flexible wire core, light non-woven fabric and a polyvinyl chloride elastomer sheath;
the pair twisted wire group unit consists of 2 pairs of twisted wire groups and an aluminum-plastic composite film shielding layer;
the pair of twisted line groups are formed by twisting 2 5 types of net wire cores in a manner of facing;
the 2 pairs of twisted wire sets are arranged in parallel, and a flat twisted wire set unit is formed by coating a layer of aluminum-plastic composite film shielding layer outside the twisted wire sets;
one end of the flat twisted pair unit is set as a filling cable core, 5 flexible cable cores are sequentially arranged along the periphery of one side of the filling cable core, the other end of the twisted pair unit extends towards the outer side and is arranged between the starting end and the tail end of the 5 flexible cable cores, integral cabling is carried out to form a round cable core, a layer of light non-woven fabric is sequentially wrapped outside the round cable core, and a layer of.
The utility model has the advantages that:
the utility model discloses adopt from filling structure during stranding, put pair strand group unit at the stranding center, arrange 5 flexible sinle silks in proper order along filling cable core one side periphery, the other end setting of pair strand group unit is between 5 flexible sinle silks's top end, be in order to realize the self-filling of stranding sinle silk structure, no longer additionally pack flexible material, directly will not realize self-filling through the stranding overmould extrusion to pair strand group through 2 pairs of not having through compound hank, fill back cable construction rounding, the stranding diameter reduces 1-2 mm.
The cable is good in flexibility, the cable is of a self-filling cabling structure, the size of the cable is reduced, and the bending radius is reduced to 7.5 times from the original 10 times of the diameter of the cable.
The 5-core wire conductor is stranded by adopting ultra-fine 6-class tough-copper monofilaments, and the inner conductor is ultra-soft and is suitable for frequent bending when the cable is used; the wear-resistant high-strength polyvinyl chloride insulating layer is suitable for thin-wall wire cores, and the flexibility of the whole cable in bending is improved.
The selection of the light non-woven fabric wrapping and the soft wear-resistant ultraviolet-resistant high-elasticity polyvinyl chloride protective layer further ensures the flexibility of the cable and the requirement of outdoor use.

Detailed Description
As shown in FIG. 1, FIG. 2 and FIG. 3, the thickness of the film is 2X2X0.5mm +5X0.4mm2The specification of the cable is explained as an example.
The utility model provides a 2 to 5 cores from filled formula flexible cable, includes twisted pair group unit 1, flexible sinle silk 2, light-duty non-woven fabrics 3, polyvinyl chloride elastomer sheath 4.
The pair-twisted wire group unit 1 is composed of 2 pairs of pair-twisted wire groups 1-1 and an aluminum-plastic composite film shielding layer 1-2. The 2 pairs of twisted-pair units 1-1 are arranged in parallel, and a shielding layer 1-2 made of aluminum-plastic composite film is coated outside the twisted-pair units to form a flat twisted-pair unit 1 by extrusion.
The pair of twisted wire groups 1-1 are formed by twisting 2 5 types of network wire cores 1-1-1 in a manner of facing.
The conductor of the 5-type network cable core 1-1-1 is single tough pitch copper with the diameter of 0.5mm, and polyethylene insulating layers with different colors are coated outside the single conductor and have the diameter of 0.92-0.95 mm.
The flexible wire core 2 is formed by stranding a plurality of ultra-fine 6-class tough-copper conductors 2-1 and coating a high-strength polyvinyl chloride insulating layer 2-2 outside the flexible wire core, the strength of the insulating layer is higher than that of a traditional insulating layer, the flexible wire core is suitable for producing thin-wall flexible wire cores, the diameter of the wire core is 1.1mm, certain extrusion force of a cabling mold is resisted when cabling is self-filled, and the structure of the plurality of ultra-fine 6-class tough-copper conductors 2-1 is 52/0.1.
