Abstract
Provided in the invention is a high-flexibility non-toxic low-smoke halogen-free environment-friendly drag chain cable. The number of times for chain dragging can reach the thousands of times; the cable has characteristics of good compressive and tensile properties, high flexibility, good non-toxic low-smoke halogen-free environment-friendly performances, and long service life; and the long-term safety operation of equipment can be guaranteed. The cable comprises an outer sheath, a metal shielding layer, and a metal foil shielding layer, wherein the cross sections of the units are in circular ring shapes and are units are arranged successively from outside to inside. A central cavity is formed in the inner wall of the metal foil shielding layer; a finished cable body is arranged in the central cavity. The finished cable unit contains core wires and tensile fillers; all core wires are twisted to form the finished cable unit; and the gap among the core wires is filled with the tensile fillers. Each core wire contains an insulating layer arranged at an outer layer and a conductor arranged at an inner layer. The outer sheath is a polyurethane outer sheath; the metal shielding layer is a tin-plated pure copper metal shielding layer; and the insulating layers are polypropylene inner-core insulating layers. The conductors are formed by twisting of high-flexibility superfine tough copper wires.

A kind of high flexibility nontoxic low-smoke halogen-free environment drag chain cable, it is characterized in that: it cross section comprising that ecto-entad is arranged in order is circular oversheath, metal screen layer, metal forming shielding layer, central cavity is formed in the inwall of described metal forming shielding layer, stranding is provided with in described central cavity, described stranding specifically comprises heart yearn, tension filler, the stranded formation stranding of all heart yearns, described tension filler is filled with in space between the heart yearn of formation stranding, described in every root, heart yearn comprises outer field insulating barrier, the conductor of internal layer, described oversheath is specially polyurethane oversheath, described metal screen layer is specially tin-plated pure copper metal screen layer, described insulating barrier is specially polypropylene inner core line insulating layer, described conductor is specifically closed by the superfine smart tough pitch copper skein silk of high flexibility and forms.
It is further characterized in that:
Described oversheath is specially high-elasticity halogen-free environment-protecting polyurethane oversheath, and its resistance to oil stain, elasticity are high, greatly can reduce the wearing and tearing in drag chain, thus significant prolongation useful life;
Described tension filler is specially tension filament, and preferably, tension filament is specially Kev and draws anti-elater;
Described metal forming shielding layer is specially aluminium foil shielding layer, its can effectively anti-stop signal excessive;
Preferably, described stranding includes 13 heart yearns, and it is according to the stranded formation stranding of the layout of 4+9, and nine heart yearns being positioned at outside are surrounded on the periphery of four heart yearns at center, are furnished with tension filler in the gap between the described heart yearn in outside and the heart yearn at center.
After adopting structure of the present invention, oversheath is specially polyurethane oversheath and makes structure have high mechanical resistant fatigue; While being provided with tin-plated pure copper metal screen layer, be also provided with metal forming shielding layer between heart yearn and metal screen layer, thus anti-EMC interference effect is fabulous; Be provided with high resilience polyurethane oversheath, the inner insulating layer of heart yearn adopts the polypropylene material that resilience is very high simultaneously, substantially increase tension anti-pressure and abrasion-proof performance, and be filled with described tension filler in space between the heart yearn forming stranding, improve overall tensile property; To sum up, its drag chain number of times can reach millions, also has that resistance to compression tensile property is good, the feature of the nontoxic low smoke and zero halogen environmental protection of high flexibility simultaneously, long service life, guarantees that the long-term safety of equipment is run.
Accompanying drawing explanation
Fig. 1 is the structural representation sketch of specific embodiments of the invention;
Title in figure representated by sequence number is as follows:
Oversheath 1, metal screen layer 2, metal forming shielding layer 3, central cavity 4, heart yearn 5, tension filler 6, insulating barrier 7, conductor 8.
Embodiment
A kind of high flexibility nontoxic low-smoke halogen-free environment drag chain cable, see Fig. 1: it cross section comprising that ecto-entad is arranged in order is circular oversheath 1, metal screen layer 2, metal forming shielding layer 3, central cavity 4 is formed in the inwall of metal forming shielding layer 3, stranding is provided with in central cavity 4, stranding specifically comprises heart yearn 5, tension filler 6, the stranded formation stranding of all heart yearns 5, tension filler 6 is filled with in space between the heart yearn 5 of formation stranding, every root heart yearn 5 comprises outer field insulating barrier 7, the conductor 8 of internal layer, oversheath 1 is specially polyurethane oversheath, metal screen layer 2 is specially tin-plated pure copper metal screen layer, insulating barrier 7 is specially polypropylene inner core line insulating layer, conductor 8 is specifically closed by the superfine smart tough pitch copper skein silk of high flexibility and forms.
Oversheath 1 is specially high-elasticity halogen-free environment-protecting polyurethane oversheath, and its resistance to oil stain, elasticity are high, greatly can reduce the wearing and tearing in drag chain, thus significant prolongation useful life;
