Abstract
The utility model relates to a cable conductor, in particular to a spiral conductor for anti-tensile cable, which comprises a conductor. The utility model is characterized in that: both ends of the conductor are respectively connected with an anti-tensile core body, and the conductor is twisted on the surface of the anti-tensile core body spirally according to the fixed pitch. The utility model has the advantages of large conductor section, uneasy breaking, good conductor expansibility, strong tensile strength and simple production process.
Description
Technical field
The utility model relates to a kind of cable conductor, especially relates to a kind of tension cable spiral conductor.
Background technology
The soft junction structure conductor of cable industry employing at present is mainly 5 classes or the 6 class flexible conductors that meet the cable conductor regulation stranded or that bundle closes.0.15 5 classes of～1.5 square millimeters of small bores or the structure of 6 class flexible conductors are: with filament diameter is the thin copper wire of 0.15～0.2mm, annealed after, close according to certain pitch bundle, form the soft junction structure conductor meet a uniform section and D.C. resistance requirement.Adopt the cable of this kind conductor, in making installation and use, the anti-twisting property of cable conductor, resistance to tension, mechanical strength, anti-fatigue ability determine by the performance of cable conductor self.The defective and the deficiency of this kind structure are: (one) breaks in manufacturing, installation, use easily because cross-sectional area of conductor is little, and the mechanical strength of conductor self is limited, causes cable to scrap.(2) conductor consists of superfine copper single line, and conductor self does not have good extension ability, in use, when cable is extruded or is subjected to fierce force-extension, very easy broken string.
Summary of the invention
The utility model mainly is at the technical problem a little less than the little easy broken string of existing in prior technology cross-sectional area of conductor, conductor extension ability, the anti-extrusion ability of stretch-proof etc., the cable spiral conductor that provide a kind of cross-sectional area of conductor to be not easy greatly to break, the conductor extension ability is good, the anti-extrusion ability of stretch-proof is strong.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of cable spiral conductor, comprise conductor, it is characterized in that described conductor two ends are connected with the tension core body respectively, described conductor is spirally wrapped around the tensile core surface according to the fixed knot distance.The center of conductor is made of high-intensity tension core body, when conductor connects, the coupling of tension core body and conductor links together, when conductor is stretched or reverse, the tension core body can possess than the better tension of independent copper wire, anti-torsion ability, copper wire is a helical form, self has certain telescopicing performance, when cable is stretched and compress, the telescopicing performance of self can guarantee that the copper wire of conductor is not stretched or torsional deflection, reduce conductor by the possibility of its prototype structure of outside destroy, realized conductor tension, torsion proof requirement.Be characterized in: 1, the copper wire of conductor is helical form as the carrier of conduction, has certain flexible ability, does not bear the required pulling force of bearing in cables manufacturing, the use, and the needed resistance to tension of conductor is born by the high strength tension core body at center.2, in the joint that cable is installed, copper wire conductor and high strength tension core body are connected on the coupling jointly, and high strength tension core body can be shared the pulling force that should be born by conductor fully.3, cable length generally is no more than 5 meters, and current-carrying capacity of cable requires little, and the external diameter of cable is not subjected to install, environment for use limits, and does not have requirement minimum, the maximum cable external diameter.4, cable conductor integral body can be born the pulling force of copper wire pull-off force in the spiral conductor, and does not damage conductor.
As preferably, described pitch is 2 times to 3 times of tension core diameter.The pitch of spiral is 2～3 times of high strength modulus fibre diameter.Spiral conductor conductor length be 3～5 times of sub-thread conductor length, the distance after pitch described here refers to conductor shape twines in the shape of a spiral between crest and the crest.
As preferably, described conductor diameter is 2.5:1---3.5:1 with the ratio of tension core diameter.Total external diameter distance of the conductor after conductor diameter described here refers to conductor shape twines in the shape of a spiral between crest and the trough.
As preferably, described tension core body adopts high strength modulus fiber to make.High strength modulus fiber (as: aramid fiber-1414) can be stranded also can be that bundle closes or sub-thread, be nonmetal, nonmagnetic substance, the tension core body also can adopt other to possess the more new material of superior function, its tensile strength should be not less than 10 times of outer spiral conductor, and anti-twisting property should be not less than 10 times of outer contact.
As preferably, described conductor is to be closed or stranded forming by some thin copper wire bundles.The production method of spiral conductor: with the thin copper wire of some 0.10mm～0.2mm, concrete radical that adopts and brass wire diameter are by the cross-sectional area of conductor decision of actual production, and be emitted on the pay off rack of back of synnema machine or thread reaming machine, adjust suitable tension force, tension force does not break to guarantee thin copper wire, not loose strand is standard, after adjusting tension force, thin copper wire is passed together the doubling mould of synnema machine or thread reaming machine, rotate by equipment, thin copper wire is closed or twists together according to certain pitch bundle, be configured for wound conductor, strand is good or merge good thin copper wire and be wrapped in the outside of high strength modulus fiber according to a constant pitch spirality, form the conductor of cable jointly.
Therefore, the utlity model has characteristics such as cross-sectional area of conductor is not easy broken string greatly, the conductor extension ability is good, the anti-extrusion ability of stretch-proof is strong, production technology is easy.
