Abstract
The utility model discloses a high-efficiency 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 intertwisted 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; and a filling layer is disposed between the aluminum foil Mylar belt shielding layer and the cable core. The high-efficiency shielded wire is simple in structure, small in wire diameter, light in weight, low in cost and convenient to install and use; and, through adoption of the demagnetization layer, the performance of shielding external magnetic induction interference of the aluminum foil Mylar belt shielding layer is effectively enhanced, the anti-interference capability of the shielded wire is effectively improved, and the safety and the stability of lines are effectively guaranteed.
Description
Technical field
The utility model relates to a kind of cable, is specially a kind of high-efficiency shielding line.
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 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 high-efficiency shielding line, and to solve traditional shielding conductor complex structure in the prior art, the line footpath is thicker, and weight is big, and cost is better, and it is convenient inadequately to use, and shield effectiveness is not good, influences the problem of line security and stability.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of high-efficiency shielding line, it is characterized in that: include several conductors, every conductor all is coated with insulating barrier outward, the stranded formation cable core of the conductor of several coated insulation layers, 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 high-efficiency shielding line 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 high-efficiency shielding line 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, adopt the design of demagnetization layer, strengthen aluminium foil wheat drawstring screen effectively and shielded the performance that extraneous magnetic strength disturbs, promoted the antijamming capability of shielding effectively, and the line footpath is little, in light weight, is convenient to install and use, 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
