Abstract
The utility model is related to a kind of double shield netting twine, including at least two insulated core groups, at least one sheath being coated on outside insulated core group, outer electro-magnetic screen layer and oversheath, characterized in that, the outside of each insulated core group is provided with cable core group electro-magnetic screen layer.The utility model is provided with double shield due to netting twine, i.e. outer electro-magnetic screen layer and cable core group electro-magnetic screen layer, electromagnetic interference can effectively be prevented, the interference between internal cable core is greatly lowered, better ensure that communication quality, in the environment of high electromagnetic interference using can more reach good anti-jamming effectiveness, the stability and reliability of cable can be kept.
Description
Technical field
The utility model is related to a kind of network cable, more particularly to a kind of double shield netting twine.
Background technology
Communication cable is ubiquitous in the modern life, and various electromagnetic interferences are also ubiquitous, electromagnetic interference influence communication
Quality, for reduction electromagnetic interference, current communication cable is already provided with screen layer, but mostly one layer screen layer, and one layer is difficult full
Interference between the anti-jamproof requirement of foot, particularly internal cable core still has, therefore studies a kind of double shield netting twine very
It is necessary.
The content of the invention
There is provided a kind of double shield netting twine aiming above mentioned problem for the purpose of this utility model.
The technical scheme that the utility model is used is：A kind of double shield netting twine, including at least two insulated core groups, bag
At least one sheath, outer electro-magnetic screen layer and the oversheath overlayed on outside insulated core group, it is characterised in that each insulated core
The outside of group is provided with cable core group electro-magnetic screen layer.
Described outer electro-magnetic screen layer mesh grid screen layer.
Described cable core group electro-magnetic screen layer is aluminium foil layer.
Described every group of cable core 1-12 root cable core of insulated core group.
The beneficial effects of the utility model：Due to netting twine there is provided double shield, i.e., outer electro-magnetic screen layer and cable core group electromagnetism
Screen layer, can effectively prevent electromagnetic interference, and the interference between internal cable core is greatly lowered, communication quality is better ensured that,
High electromagnetic interference environment using can more reach good anti-jamming effectiveness, the stability of cable can be kept and reliable
Property.
Brief description of the drawings
Fig. 1 is the cross-sectional view of the one of embodiment of the utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the present utility model, rather than all
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not before creative work is made
The every other embodiment obtained is put, the scope of the utility model protection is belonged to.
As shown in figure 1, the utility model includes at least two insulated core groups 1, is coated on outside insulated core group at least
One sheath 4, outer electro-magnetic screen layer 2 and oversheath 3, each insulated core group include 1-12 roots insulated core 11.This implementation
Example is provided with 4 groups, and every group constitutes insulated core provided with two insulated cores, i.e., each metal-cored layer insulating of outside burden one, often
The outside of individual insulated core group 1 is provided with cable core group electro-magnetic screen layer 12.The outer mesh grid screen layer of electro-magnetic screen layer 2.Cable core group electricity
Magnetic masking layer 12 is aluminium foil layer.A piece insulated core, is exactly the insulating barrier of a wire periphery cladding, usually fire-retardant insulation
Plastic layer, one group is exactly many such cable cores.
The utility model is due to being provided with netting twine there is provided double shield, i.e., outer electro-magnetic screen layer and cable core group electromagnetic shielding
Layer, can effectively prevent electromagnetic interference, the interference between internal cable core is greatly lowered, communication quality is better ensured that, in height
The environment of electromagnetic interference can keep cable stability and reliability using can more reach good anti-jamming effectiveness.
