Abstract
The utility model discloses a pair-twisted combined externally coated shield cable for control, belonging to the technical field of cables. The pair-twisted combined externally coated shield cable for control comprises a cable core, a shield layer outside the cable core, and a sheath, and is characterized in that the cable core is formed by twisting a reinforcement bar arranged at the center of the cable core and three shield wires evenly surrounding the periphery of the reinforcement bar, the shield layer is a composite shield layer consisting of a lapped aluminum plastic shield tape and a densely woven tin-plated wire screen, each shield wire is formed by twisting two insulated wire cores and the tin-plated copper wire earthing wire and then lapping the aluminum plastic shield tape; and the cable core is externally and sequentially lapped with a polyester tape and an aluminum plastic shield tape, woven with the dense tin-plated wire weaving screen and extruded with the butyronitrile polyvinyl chloride elastomer sheath. The pair-twisted combined externally coated shield cable for control is simple and reasonable in structure, easy to produce and manufacture, low in cost, and good in usability, has the advantages of being wholly soft and bend-resistant, good in shielding effect, strong in anti-interference capability and the like, and is applicable to electrical system engineering under various industrial control environments.
Description
Technical field
The utility model relates to a kind of structure of cable, and especially a kind of control belongs to the cable technology field with the outer structure of covering shielded type cable of pair twist combination.
Background technology
At present; the serial cable of shielding control has found broad application in the electrical system engineering of industries such as machinery, electronics; but continuous variation along with site environment; improving constantly of engineering application requirements; a lot of occasions to the requirement of this type of cable performance also in continuous increase; adapting to the operation of all kinds of homes and particular surroundings, except that antijamming capability is strong, also must possess softness, suitablely frequently move, characteristic such as tension.So, research and develop the cable that a kind of energy satisfies above every requirement, be a urgent task of each cable R﹠D institution and electric wire manufacturing enterprise.
The utility model content
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, and the control that characteristics such as a kind of antijamming capability frequently moves by force, soft, suitable, tension are provided is with the outer shielded type cable that covers of pair twist combination.
The purpose of this utility model is achieved through the following technical solutions: control is with covering shielded type cable outside the pair twist combination, comprise cable core, outer screen and the sheath of cable core, it is characterized in that, described cable core is by the reinforcement that is arranged on the cable core center, uniform ring three stranded forming of shielding conductor around the reinforcement periphery, described screen weaves the composite shielding layer that close net is formed by the tin plated wire of wrapped plastic-aluminum mask tape and braiding, and described shielding conductor thoroughly does away with the edge core by two and wrapped plastic-aluminum mask tape, the stranded back of tinned copper wire earth connection constitutes; The wrapped successively outward polyester belt of described cable core, wrapped plastic-aluminum mask tape, braiding tin plated wire weave close net, extrude butyronitrile polyvinyl chloride elastic body jacket.
Described insulated wire cores constitutes by extruding polyolefin insulation layer on the zinc-plated soft copper tow of the multiply conductor.
Described reinforcement constitutes by extruding polyolefin insulation layer on 19 strands of stranded galvanized mild steel silks.
The color difference of described insulated wire cores.
Advantages such as the utility model is simple and reasonable, manufactures easily, and cost is low, and serviceability is good, has whole softness and anti-bending, and shield effectiveness is good, and antijamming capability is strong are applicable to the electrical system engineering of all types of industries under controling environment.Conductor uses the zinc-plated soft copper tow of multiply, makes conductor oxidative phenomena can not take place.Conductor extrudes polyolefin insulation layer outward, and this material has the characteristic of excellent water tolerance, mechanical strength, electrical insulating property.The insulated wire cores pair twist of different colours adds wrapped plastic-aluminum mask tape behind the tinned copper wire earth connection, play preliminary shielding action, place 19 strands of stranded galvanized mild steel silks that insulating barrier is arranged in the middle of the cable core, play tension, the anti-effect of circumnutating, the steel wire insulating barrier also adopts polyolefin.The outside wrapped polyester belt of cable core is with the tight and rounding of cable core that guarantees to combine.The shielding of cable is to weave the composite shielding layer that close net constitutes by adding tin plated wire on the plastic-aluminum mask tape, and shielding density reaches more than 90%, has strengthened the cable shield effect greatly, improves antijamming capability, guarantees the normal use of cable under modern complex electromagnetic environment.Oversheath adopts butyronitrile polyvinyl chloride elastomer sheathing material, should the cost of material is low, elasticity height, permanent deformation be little, and have advantages such as certain oil resistant, ageing-resistant, high-low temperature resistant, anti-ozone, chemical-resistant resistance.Advantages such as this cable has whole softness and anti-bending, and shield effectiveness is good, and antijamming capability is strong are applicable to the Equipment Control operation of a plurality of industries, have vast market prospect.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: the zinc-plated soft copper tow of 1 multiply conductor, 2 polyolefin insulation layer, 3 stranded galvanized mild steel silks, 4 plastic-aluminum mask tapes, 5 polyester belts, 6 plastic-aluminum mask tapes, 7 tin plated wires weave close net, 8 butyronitrile polyvinyl chloride elastic body jackets, 9 tinned copper wire earth connections.
Embodiment
Control is with covering shielded type cable outside the pair twist combination, comprise the butyronitrile polyvinyl chloride elastic body jacket 8 that the tin plated wire of the wrapped successively polyester belt 5 of cable core, cable core, wrapped plastic-aluminum mask tape 6, braiding weaves close net 7, extrudes outward, screen weaves the composite shielding layer that close net is formed by the tin plated wire of wrapped plastic-aluminum mask tape and braiding.
Cable core is by the reinforcement that is arranged on the cable core center, uniform ring three stranded forming of shielding conductor around the reinforcement periphery.Shielding conductor thoroughly does away with the edge core by two and wrapped plastic-aluminum mask tape, tinned copper wire earth connection 9 stranded back 4 constitutes.
Insulated wire cores constitutes by extruding polyolefin insulation layer 2 on the zinc-plated soft copper tow of the multiply conductor 1, the color difference of insulated wire cores, the convenient differentiation.
Reinforcement constitutes by extruding polyolefin insulation layer on 19 strands of stranded galvanized mild steel silks 3.
