Abstract
The invention discloses a high-flexibility rubber-sheathed cable. The cable comprises a wire core consisting of a flexible conductor and a rubber insulating layer extruded outside the flexible conductor, wherein a cable core is formed by stranding a plurality of wire cores; a filling core is arranged in a gap among the wire cores; the cable core is wrapped by nonwoven fabric; an outer sheath is arranged on the outermost layer; and the flexible conductor is formed by twisting a plurality of strands of soft copper wires or tinned copper wires which are subjected to double annealing and have the diameter of 0.16mm or 0.20mm. The rubber insulating layer is prepared by mixing and vulcanizing ethylene propylene terpolymer with glue content of 40 percent and chlorinated polyethylene; the filling core is a hemp rope covered by rubber by extrusion; and the extruded hemp rope is then vulcanized. The outer sheath used is soft chloroprene rubber mixed sulfide rubber with glue content of 50 percent. The cable has high bending performance and can be bent to 3 to 5 times the external diameter of the cable without being damaged; and particularly when the cable is repeatedly bent, the service life of the cable is greatly prolonged because mutual sliding can be performed in the cable so as not to damage the insulation.
Description
Technical field
The present invention relates to a kind of cable, specifically is a kind of high flexibility rubber cable.
Background technology
Cable is used for transferring electric power, when cable is used for frequent crooked place, because the radius of repeated bending or bending is too small, can cause the conductive copper wire fracture of cable, causes electric power transfer to be interrupted, and power consumption equipment quits work.The for example frequent gantry that moves, drag chain, robot arm, the loading and unloading of automation and erection unit, transfer system etc. need the cable use occasion of continuous bend.The cable of Shi Yonging in the past, 0.2mm can only be accomplished in the copper wire individual thread footpath that conductor is used; Can not well solve the annealing problem after the copper wire wire drawing, the copper wire oxidation stain is not exactly an annealing slack when not being annealing, in order to prevent the copper wire variable color, can only reduce the pliability of annealing back copper wire.Simultaneously, insulation rubber and sheath rubber that prior cable is used also are difficult to improve pliability.Permission bending radius when cable uses is that 12 times of the outside diameter of cable are arranged, and this cable can only use half a year in frequent crooked occasion, and the conductor copper wire just ruptures, the cable that need more renew, and this user to cable has brought very big trouble.
Summary of the invention
Invent technical problem to be solved and provide a kind of high flexibility rubber cable, this cable can stand the bending radius littler than normal cable (outside diameter of cable 3～5 times) still can operate as normal, and after cable stands frequent bending, copper wire in the conductor does not rupture, insulation is not ftractureed, guaranteed the use of cable, improved the useful life of cable greatly in frequent crooked occasion.
For achieving the above object, high flexibility rubber cable provided by the invention, comprise the core of forming by the fexible conductor rubber insulation outer with being extruded in fexible conductor, some cores are twisted into cable core, space between cable core is provided with filled core, the wrapping of cable core external application non-woven textile, outermost layer is provided with oversheath, and described fexible conductor adopts the soft copper silk of 0.16mm or 0.20mm diameter or tinned copper wire multiply bundle strand to form.
The raw material of above-mentioned soft copper silk or tinned copper wire is annealing soft thin copper wire or a tinned copper wire, after the multiply bundle is twisted into conductor, extrude insulation before, carry out annealing in process again one time, i.e. annealing for the second time guarantees that copper wire has excellent flexibility.
Above-mentioned rubber covered material preferably adopts the ethylene propylene diene rubber of gel content 40% and haloflex mixing sulfuration to form, promptly increase haloflex in the original Ethylene Propylene Terpolymer rubber that uses, the ratio of ethylene propylene diene rubber and haloflex is (6.5-7.5): 3.This rubber material has good flexibility and elasticity, and the anti-intensity that rises of insulation reaches more than the 6.5MPa, and elongation at break reaches more than 300%, has than higher mechanical strength, rub resistance, not easy to crack.
Above-mentioned filled core is preferably the rope made of hemp that extrudes rubber, and the rope made of hemp after extruding carries out vulcanizing treatment again.Increase the mutual sliding of filling at surperficial powder coating simultaneously with cable core; Wrap up with soft non-woven textile behind the stranding, can not be too tight during wrapping.
Above-mentioned oversheath preferably adopts the soft neoprene mixing hard rubber of gel content 50%.This hard rubber has good flexibility and elasticity, has oil resistant, ageing-resistant, flame-retarding characteristic simultaneously.
Can be coated with sticking silicone oil for the indivedual cable cores surface in the multi-core cable structure, the mutual sliding of core when increasing bending reduces the wearing and tearing between core when crooked.
Beneficial effect of the present invention:
The present invention is by the improvement of the conductor material of cable use, and the rubber insulation and the sheath of application highly-flexible, the rope made of hemp that is easy to crooked coating rubber by use is filled, make cable have extraordinary flexibility, have good bending property, cable can bend to 3-5 times the outside diameter of cable and not damage; When particularly passing through repeated bending, owing to can slide mutually in cable inside, not easy damaged insulation is so improved the useful life of cable greatly.When of the present invention, test cable is after using a year and a half in checking, and the every performance of cable still keeps normally, the phenomenon that conductor thread core fracture or rubber ftracture do not occur, than very big prolongation has been arranged in useful life of prior cable.
The operating voltage 0.6/1kV of this cable, sectional area are 0.75-300mm
2, the cable core number is the 1-5 core, for 6mm
2Following cable can be processed into 37 cores.Cable have oil resistant, ageing-resistant, fire-retardant, be easy to advantage such as bending, the place that has well solved frequent bending uses cable that the technical problem of conductor copper wire fracture often takes place.
