Abstract

The invention relates to an intrinsically safe explosion-proof flexible spring cable for data transmission. At least one pair of stranded wires and at least one insulation wire core are twisted into a cable; a split phase composite shielding layer is disposed out of the pair of stranded wires, and a small sheath is extruded out of the shielding layer; the outer part of the cable core is in turn provided with a cable wrapping layer, a total composite shielding layer and an outer sheath layer; and a high temperature resistant high flame retardant material is disposed as a filler in a gap between the cable cores. The cable has multiple integrated performances such as electromagnetic interference resistance, explosion prevention, voltage resistance, bending resistance, corrosion resistance, weather resistance, high flame retardance, good telescopic performance and the like, and is suitable for line supporting demand of mobile electric equipment with high requirement on performances such as explosion prevention, electromagnetic interference resistance and the like in multiple fields.

Description

The research staff of company to cable anti-explosion safety required on the automation equipment, anti-interference, at a high speed, general character such as accurate, flexible, compound, environmental protection and a key technology difficult problem tackle key problems; Developed to possess to adapt to and back and forth do not stopped to move and three-dimensional mobile twisting, the flexible superior Special spring cable of rebound performance of adding that does not stop, and to the new product of proposition requirements at the higher level on fire-retardant Halogen, anti-explosion safety, the performance index such as anti-interference.
Summary of the invention
The present invention is directed to the supporting requirements that project constructions such as communication, medical mobile device, electric locomotive industry, mechanical engineering, equipment are installed and keeped in repair employed mobile electrical equipment circuit,, job site ground cable unstable for fear of various electromagnetic interference signal transfer of data disorderly draws unsafe factors such as disorderly dragging the confusion that causes, accumulation and researched and developed a kind of multiple combination property intrinsic safe explosion-proof transfer of data flexure spring cables such as anti-electromagnetic interference, explosion-proof, proof voltage, anti-bending, corrosion-resistant, weather, high flame retardant, flexible rebound performance be good that have.
The present invention realizes that through following technical scheme by the stranded stranding of single core insulation core of a pair of twisted wire pair and at least one core, wherein twisted wire pair is provided with the phase-splitting composite shielding layer outward at least, and screen extrudes the little sheath of flexible polyolefin mixture outward; Cable core is set as cable lapping layer, total composite shielding layer, outer jacket outward successively; High temperature resistant, high flame retardant material is set as inserts in the space between the cable core.After cable extrudes oversheath, it is neatly enclosed on round steel pipe, carry out air-cooled moulding.
Described twisted wire pair, single core insulation core are made up of the outer regular stranded low smoke and zero halogen environmental protection elastomeric flexible polyolefin insulation layer that extrudes of the zinc-plated high flexibility alloy of multiply silk respectively.
Described phase-splitting composite shielding layer, total composite shielding layer are made up of the wrapped back braiding of light-duty ultra-thin blue aluminium-plastic tape tinned copper wire screen respectively.
Described stranding lapping layer adopts the high flame retardant glass fibre belt.
Described inserts adopts high temperature resistant, high flame retardant aramid fiber.
Described outer jacket adopts low smoke and zero halogen environmental protection elastomeric flexible polyolefine material.
Main parts size of the present invention adopts novel environment friendly Halogen material regeneration material manufacture, reduces and pollutes operational environment; Rational in infrastructure simple, to manufacture easily, cost is low, and new construction spring helical design makes wiring convenient, and folding and unfolding is convenient, the cable utilance high; The NEW TYPE OF COMPOSITE shielding process is provided with, and has strengthened the feasible number transmission more stable of explosion-proof performance, quick, safety, accurate.
Characteristics such as the present invention has that good, the low inductance of insulation resistance height, dielectric strength, Low ESR, antijamming capability are strong, proof voltage grade height, corrosion resistant, weather, signal transmission are fast accurate are applicable to the high supporting demands of mobile electric equipment circuit of performance requirement such as multiple field is explosion-proof, anti-electromagnetic interference.
