Description
Technical field
The present invention relates to and often bend, reverse, have the flexible cable used in the environment of electromagnetic interference, specifically about the flexible cable with function of shielding.
Background technology
At present, conventional shielded flexible cable is that the copper conductor (the 5th class conductor) by soft level adds common polyvinyl chloride (PVC) flexible plastics insulation, and carry out proof copper-wire braided again after each core stranding, last coated polyvinyl chloride flexible plastics sheath produces.Its product structure and production technology are simple, buying is convenient, are widely used.But the poor anti jamming capability of this kind of flexible cable, grounded capacity is strong, add in use procedure often reverse, bending, cause insulation easy damaged to be short-circuited, finally affect the useful life of flexible cable.
Along with scientific and technological development, the consciousness of people to quality, safety, environmental protection constantly strengthens, also more and more higher to the requirement of product.Under this background, design a kind of New Type of Cable Products, while making the work of cable normal power-up, antijamming capability can be strengthened, also possesses the characteristic of good moisture resistance, oil resistant, corrosion-resistant, resist bending and torsion, cable is used more relieved, safer, useful life is also longer aobvious even more important.
Summary of the invention
For above problem, the purpose of this utility model is to provide a kind of Novel shielding flexible cable, is the improvement carried out on the basis of universal shield flexible cable.The copper conductor (the 5th class conductor) of soft level remains unchanged, make igelite insulation into flame-proof elastomer Insulation Material and nylon sheath wire community, after many core dextrad strandings, gap adds filler, the wrapped isolation strip of appearance, makes the cable core sub-circular after stranding.An earth connection tinned copper wire braiding lenticular wire, cable core carries out the braiding of external shield again together with this braiding lenticular wire, and braid is vertical bag separator outward, and oversheath adopts flame-retardant flexible level elastomer material, ensure that fire-retardant, the resistance to wear of cable, soft, hold flexible advantage.
The technical solution of the utility model is achieved in the following ways: a kind of Novel shielding flexible cable, by four copper conductors, flame-proof elastomer insulate, nylon sheath wire, filler, isolation strip, tinned copper wire braiding lenticular wire, braided overall-shielding and flame-retardant flexible elastomer sheathing material composition, the outer rim of described every root copper conductor is all coated with fire retardant elastic insulator and nylon sheath wire, form an insulation community, after four core dextrad strandings of four insulation communities, its gap adds filled nylon thing, the wrapped isolation strip of appearance, cable core is made to be circular, parallel with tinned copper wire braiding lenticular wire, outside coated braided overall-shielding again, the outer wrapped isolation strip again of braided overall-shielding, use flame-retardant flexible elastomer sheathing material coated as sheath outside isolation strip again, it is characterized in that: the tinned copper wire being provided with a placement parallel with cable core between described isolation strip and braided overall-shielding weaves lenticular wire.
Described flame-proof elastomer insulation is the insulation of TPE plastic body, and flame-retardant flexible elastomer sheathing material is the insulation of TPE flexible plastics body.
The utility model, considers practicality and the durability of shielded flexible cable, replaces polyvinyl chloride (PVC) plastics with flame-proof elastomer, enhances anti-flammability, flexibility, resist bending, resistance to torsion; With the addition of nylon layer, enhance wear-resisting, moisture resistance, oil resistant, the corrosion resistance of insulating barrier; With the addition of the earth connection of braiding lenticular wire, enhance ground integrity, reliability; External shield count is not less than 80%, enhances cable antijamming capability; Have employed flame-retardant flexible level elastomer oversheath, what enhance cable enhances anti-flammability, flexibility, resist bending, resistance to torsion.
Accompanying drawing explanation
Fig. 1 is circular section of the present utility model schematic diagram.
In figure: 1 copper conductor, 2 fire retardant elastic insulators, 3 nylon sheath wires, 4 fillers, 5 isolation strip, the total barrier band of 6 braiding, 7 flame-retardant flexible elastomer material, 8 tinned copper wire braiding lenticular wires.
Embodiment
Known by Fig. 1, a kind of Novel shielding flexible cable, by four copper conductors 1, fire retardant elastic insulator 2, nylon sheath wire 3, filler 4, isolation strip 5, tinned copper wire braiding lenticular wire 8, braided overall-shielding 6 and flame-retardant flexible elastomer sheathing material 7 form, the outer rim of described every root copper conductor 1 is all coated with fire retardant elastic insulator 2 and nylon sheath wire 3, form an insulation community, after four core dextrad strandings of four insulation communities, its gap adds filler 4, the wrapped isolation strip 5 of appearance, make cable core sub-circular, parallel with tinned copper wire braiding lenticular wire 8, outside coated braided overall-shielding 6 again, wrapped isolation strip 5 again, outside, use flame-retardant flexible elastomer sheathing material 7 coated as sheath again, the tinned copper wire being provided with a placement parallel with cable core between described isolation strip 5 and braided overall-shielding 6 weaves lenticular wire 8.The coated fire retardant elastic insulator 2 of squash type and nylon sheath wire 3 is adopted outside described copper conductor.
Production procedure of the present utility model is:
1, insulate operation: adopt the coated fire retardant elastic insulator 2 of squash type and nylon sheath wire 3 outside copper conductor 1, adopts co-extrusion mode to realize community's insulation.Described fire retardant elastic insulator is the insulation of TPE plastic body.
2, cabling procedure: many insulated wire cores dextrad twisted synthesizing cables, suitably add filler 4, isolation strip overlap is wrapped, makes cable core sub-circular, Stability Analysis of Structures.
3, operation is shielded: by cable core and the parallel placement of a tinned copper wire braiding lenticular wire 8, carry out the braiding of external shield as new cable core, count is not less than 80%.
4, outer jacket operation: the total barrier band 6 of vertical bag braiding outside woven shield, and coated flame-retardant flexible level elastomer material 7 sheath.Flame-retardant flexible elastomer sheathing material is the insulation of TPE flexible plastics body.
The present invention requires GB/T5023-2008 according to the national standard of shielded flexible cable, and the basis of universal shield flexible cable is improved.This shielded flexible cable had both met the requirement of International Electrotechnical Commission (IEC) and national cable standard (GB), as physical property, electrical property etc., possessed again fire-retardant, soft, moisture resistance, wear-resisting, durable advantage, extended useful life, saved use cost.The mechanical performances such as the interpolation of nylon layer not only increases the insulation property of flexible cable, also enhances the wear-resisting of insulating barrier, moisture resistance.The lenticular wire of tinned copper wire braiding improves the ground connection performance of cable, than common copper cash more firmly, more stable, safer.Outer highdensity braid greatly strengthen the antijamming capability of cable, makes cable in use more stable, safer.
