The invention belongs to the technical field of cable application and relates to a multi-core control cable, in particular to a flexing-resistant multi-core control cable which is applicable to rated voltage of 450V/750V and particularly applicable to electric welding machines. The technical scheme includes that the flexing-resistant multi-core control cable comprises copper conductors (1) and insulating layers (2), the copper conductors (1) and the insulating layers (2) form a plurality of core wires (6), the core wires in monolayer arrangement and packing (3) among the core wires are stranded into a cable core (7), and a lapped covering (4) is arranged outside the cable core (7) and wrapped by a sheath (5) in an extruded manner. After the technical scheme is adopted, the cable core is uniform in stress, and the cable becomes flexible, good in flexibility and flexing-resistant.
Description
Technical field
The present invention relates to a kind of multi-core controlled cable, particularly a kind of Anti-warping multicore control cable.Be applicable to the cable of rated voltage 450/750V, be particularly useful for welding machine cable.The invention belongs to the cable application technical field.
Background technology
Welding machine cable belongs to the cabtyre cable class, and it is generally the single line core, and conductor is oxygen-free copper, brass wire diameter is little, radical is many, generally is twisted into strand by many copper wires, is twisted into conductor by many strands again, so welding machine cable line body is thicker, hundreds of on copper wire.Conductor outsourcing one deck heat-resistant polyester is film-insulated.Home products generally only has 1～2 month useful life at present.
The requirement of welding machine cable:
(1) under the condition of low-voltage, large electric current, works, require to have certain patience.
(2) the motor lead cable is mobile continually, turns round around and discharges, and requires softness, good bending property.
(3) in dispensing, be vulnerable to scraping, wiping of sharp-pointed steel component, so require the good mechanical properties such as cable insulation is anti-tear, wear-resisting.
(4) environment for use complicated condition such as Exposure to Sunlight, water boil, contact muddy water, machine oil, soda acid liquid etc., require to have certain weatherability and oil resistant, solvent resistance.
(5) run into sometimes the hot weld part, require resistance to heat distorsion good.
(6) often mobile, require external diameter little, lightweight.
China Patent Publication No. CN201285672Y is openly with the cable of electric welding line of control line.It is surrounded by insulating barrier outside wire, the control line of subsidiary insulating coating outside insulating barrier.It is single cored structure, and the line body is thicker, and bending property is not good, Heavy Weight.
The open Flexible electric cable of China Patent Publication No. CN2522985Y, it is comprised of wire, insulating barrier, overcoat, fortifying fibre heart line is arranged in the middle of it, extrude the heart yearn of wear-resistant plastic all around outward for the flexible conductor of stranded bunchy, heart yearn is twisted into the heart yearn group, group and group be round the stranded formation cable core of fortifying fibre heart line, and that cable core is extruded outward is wear-resisting, adhesiveness is little and flexible high sheath.Heart yearn is that sandwich construction is arranged, complex structure, and flexibility is poor; Wear-resisting, adhesiveness is little and flexible high sheath adopts Polyurethane, weatherability, oil resistant or solvent resistance, resistance to heat distorsion is not enough.
Summary of the invention
The objective of the invention is for the deficiencies in the prior art, provide a kind of core stressed even, soft Anti-warping multicore control cable.
For realizing above-mentioned technical purpose, the present invention is by the following technical solutions: a kind of Anti-warping multicore control cable, include copper conductor and insulating barrier, described copper conductor and insulating barrier consist of heart yearn, many heart yearns of monolayer alignment and the filling in the middle of the Duo Gen heart yearn are twisted into cable core, cable core is provided with lapping layer outward, and lapping layer extrudes oversheath outward.
Further, described insulating barrier is low retraction polyvinyl chloride insulation layer.
Further, described filling is soft stuffing material; Described lapping layer is the nonwoven fabrics lapping layer.
Further, described oversheath is take the oil resistant cross-linking radiation sheath of second third as base.
Further, described soft stuffing material is the rope made of hemp.
After adopting technique scheme, the present invention has following beneficial effect:
(1) improve existing single cored structure, adopt the multicore structure of monolayer alignment, simple in structure, in the identical situation of energising performance, core is stressed evenly, cable deliquescing, warping strength.
(2) insulating barrier is low retraction polyvinyl chloride insulation layer, in the constant situation of insulation effect, solves the large problem of retraction of radially being heated in the cable installation process.
(3) soft stuffing material and nonwoven fabrics lapping layer in the situation that guarantees mechanical performance, lighten cable, make cable easy to process.
(4) take the oil resistant cross-linking radiation sheath of second third as base, have good flexibility, oil resistant, resistance to wear, resistance to heat distorsion etc., and soft, wear-resisting.
(5) multi-thread cored structure and adopt above-mentioned Insulation Material and oversheath improves cable useful life.
(6) insulated wire cores adopts monolayer alignment during stranding, adopts in the middle of namely the soft material such as the rope made of hemp to fill, and multi-thread core distributes around it, solves the in use poor problem of the even flexibility of unbalance stress of cable.
Core of the present invention is stressed evenly, and flexibility is good.
Description of drawings
Fig. 1 is structural representation of the present invention.
Among the figure: 1, copper conductor, 2, insulating barrier, 3, fill, 4, lapping layer, 5, oversheath, 6, heart yearn, 7, cable core.
Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
Embodiment
As shown in Figure 1, a kind of Anti-warping multicore control cable includes copper conductor 1 and insulating barrier 2, also includes the heart yearn 6 that is made of copper conductor 1 and insulating barrier 2.Be provided with in the middle of the many heart yearns of monolayer alignment and fill 3, many heart yearns are twisted into cable core 7 with filling 3, the cable core 7 outer lapping layers 4 that are provided with, the lapping layer 4 outer oversheaths 5 that extrude.
Wherein: insulating barrier 2 is low retraction polyvinyl chloride insulation layers; Filling 3 is soft stuffing material, preferably the rope made of hemp; Lapping layer 4 is nonwoven fabrics lapping layers; Oversheath 5 is take the oil resistant cross-linking radiation sheath of second third as base.
The multicore structure that to improve original single line core be monolayer alignment in the situation that guarantees the energising performance requirement, makes core stressed evenly, cable deliquescing, warping strength.
Low retraction polyvinyl chloride insulation layer avoids radially being heated in the cable installation process retraction greatly.
Soft stuffing material and nonwoven fabrics lapping layer in the situation that guarantees mechanical performance, lighten cable, make cable easy to process.
Take the oil resistant cross-linking radiation sheath of second third as base, have good flexibility, oil resistant, resistance to wear, resistance to heat distorsion etc., and soft, wear-resisting.
Improve the core structure and also adopt above-mentioned Insulation Material and oversheath, cable useful life was above 6 months.
The middle rope made of hemp that adopts, multi-thread core distribute around it, make the stressed all even softnesses of cable.
The invention is not restricted to above-described embodiment, the technical scheme that all employings are equal to or the equivalence replacement forms all falls into the protection range that the present invention requires.
