Abstract
The utility model discloses a tension-type shielded wire comprising a plurality of conductors. Each conductor is wrapped in an insulating layer. The plurality of the conductors wrapped in the insulating layers are twisted with a reinforcement steel core to form a cable core; an aluminum foil Mylar belt shielding layer is wrapped around the cable core. A demagnetization layer, a woven shielding layer and a sheath layer are successively wrapped around the aluminum foil Mylar belt shielding layer. A filling layer is disposed between the aluminum foil Mylar belt shielding layer and the cable core. Through adoption of the demagnetization layer, performance of shielding external magnetic induction interference of the aluminum foil Mylar belt shielding layer is effectively enhanced, and the anti-interference capability of the shielded wire is effectively improved; through adoption of design of twisting the plurality of the conductors and the reinforcement steel core, tension resistance of the shielded wire is effectively improved; the tension-type shielded wire is simple in structure, small in wire diameter, light in weight, low in cost and easy to install and use; and safety and stability of a line are effectively guaranteed.
Description
Technical field
The utility model relates to a kind of cable, is specially a kind of tensile type shielding conductor.
Background technology
When some special occasions use cable, in order to reduce the phase mutual interference between cable self loop and to reduce the interference that comes from the cable outside, therefore also needing to take shielding measure, so-called shielding measure is to utilize the metallic shield body that main string loop and interfered loop are separated and use a kind of measure that the electromagnetic field that makes interference weakens.Shielding conductor is a kind of cable with self function of shielding, and traditional shielding conductor complex structure, the line footpath is thicker, and weight is big, and cost is better, and it is convenient inadequately to use, and the resistance to tension deficiency, and shield effectiveness is not good, influences fail safe and the stability of circuit.
The utility model content
The purpose of this utility model provides a kind of tensile type shielding conductor, and to solve traditional shielding conductor complex structure in the prior art, the line footpath is thicker, weight is big, and cost is better, and it is convenient inadequately to use, and resistance to tension deficiency, shield effectiveness are not good, influence the problem of line security and stability.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of tensile type shielding conductor, it is characterized in that: include several conductors, every conductor all is coated with insulating barrier outward, the conductor of several coated insulation layers constitutes cable core with the stranded back of reinforcement steel core, described cable core is coated with aluminium foil wheat drawstring screen, described aluminium foil wheat drawstring screen is coated with demagnetization layer, woven shield and restrictive coating outward successively, is provided with packed layer between described aluminium foil wheat drawstring screen and the cable core.
Described a kind of tensile type shielding conductor is characterized in that: described insulating barrier adopts polyvinyl chloride or semi-rigid polyvinyl chloride or polypropylene insulation material to make.
Described a kind of tensile type shielding conductor is characterized in that: described restrictive coating adopts polyvinyl chloride to make.
The beneficial effects of the utility model are:
The utility model is simple in structure, adopts the design of demagnetization layer, has strengthened aluminium foil wheat drawstring screen effectively and has shielded the performance that extraneous magnetic strength disturbs, and has promoted the antijamming capability of shielding effectively; Adopt the conductor design stranded with strengthening steel core of several coated insulation layers, promoted the resistance to tension of shielding conductor effectively; And the line footpath is little, in light weight, is convenient to install and use, and cost is low, has guaranteed fail safe and the stability of circuit effectively.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of tensile type shielding conductor, include several conductors 1, the every conductor 1 outer insulating barrier 2 that all is coated with, the conductor 1 of several coated insulation layers 2 constitutes cable cores with reinforcement steel core 3 stranded backs, cable core is coated with aluminium foil wheat drawstring screen 4, is coated with demagnetization layer 5, woven shield 6 and restrictive coating 7 successively outside the aluminium foil wheat drawstring screen 4, is provided with packed layer 8 between aluminium foil wheat drawstring screen 4 and the cable core.
Insulating barrier 2 adopts polyvinyl chloride or semi-rigid polyvinyl chloride or polypropylene insulation material to make, and restrictive coating 7 adopts polyvinyl chloride to make.
