Description
Technical field
The utility model is related to technical field of electric wires and cables, and more specifically more particularly to a kind of anti-electromagnetism PVC is led with one heart
Body electric wire.
Background technology
With the continuous renewal of the progress and various advanced instruments of Science Times, the quantity of electric wire is also with continuous
Increase, and the use environment of cable and wire also becomes increasingly complex, interfering with each other also increasingly between environmental disturbances and cable and wire
Seriously, traditional cable and wire is simple in structure, and shield effectiveness is poor, and anti-interference ability is weaker, in the serious environment of the interference of electromagnetic field
In, transmission quality is influenced, a series of problem of instrument is caused.
Utility model content
The utility model is improved the prior art for disadvantages mentioned above, provides a kind of anti-electromagnetism PVC concentric conductors electricity
Line, technical solution are as follows：
Anti- electromagnetism PVC concentric conductor electric wires, including concentric type conductor and electro-magnetic screen layer, the concentric type conductor packet
Be wrapped with electro-magnetic screen layer, be provided with the core wire wrapped up by insulating layer in the electro-magnetic screen layer, outside the concentric type conductor according to
Secondary package copper strips, twining package tape and oversheath.
Preferably, the concentric type conductor is wrapped in outside electro-magnetic screen layer in the same direction.
Preferably, the copper strips winding is wrapped in outside concentric type conductor.
Preferably, the electro-magnetic screen layer is formed by annealing proof copper-wire braided.
Preferably, the insulating layer is made of PVC material.
Preferably, the oversheath is made of PVC material.
Compared with prior art, the beneficial effects of the utility model are：The utility model by be arranged electro-magnetic screen layer and
Concentric type conductor can effectively reduce interference of the external electromagnetic wave to electric wire so that instrument is more stablized in use, protects
Transmission quality is demonstrate,proved.
Further, copper strips winding is wrapped in outside concentric type conductor, can be further reduced external electromagnetic wave to electric wire
It influences.
Further, electro-magnetic screen layer is formed by annealing proof copper-wire braided, is had good electromagnetism interference performance, is effectively carried
Height shielding rejection coefficient, each quasi-instrument can be applied in the environment of electromagnetic wave complex jamming, can resist external electromagnetic wave
Interference, ensure transmission various current signals it is safe and stable and reliable, without generate be distorted.
Description of the drawings
It is required in being described below to embodiment in order to illustrate more clearly of the technical solution of the utility model embodiment
The attached drawing used is briefly described：
Fig. 1 is the cross-sectional view of the utility model；
Including：Core wire 10, insulating layer 11, electro-magnetic screen layer 12, concentric type conductor 13, copper strips 14, twining package tape 15, oversheath
16。
Specific implementation mode
With reference to the attached drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear
Chu is fully described by, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole realities
Apply example.Based on the embodiments of the present invention, those of ordinary skill in the art are obtained without making creative work
The every other embodiment obtained, belongs to the scope of protection of the utility model.
The utility model embodiment is described in further detail below in conjunction with attached drawing, it is as follows in detail：
Anti- electromagnetism PVC concentric conductor electric wires, including concentric type conductor 13 and electro-magnetic screen layer 12, inside concentric type conductor 13
It is enclosed with electro-magnetic screen layer 12, and is wrapped in the same direction outside electro-magnetic screen layer 12, is provided with by insulating layer in electro-magnetic screen layer 12
The core wires 10 of 11 packages, wrap up copper strips 14, twining package tape 15 and oversheath 16 outside concentric type conductor 13, in the present embodiment successively
In, oversheath 16 and insulating layer 11 are made of PVC material.
Electro-magnetic screen layer 12 is formed by annealing proof copper-wire braided.
By taking theory structure combination above structure as an example, concentric conductor electric wire is a kind of to interfere with each other and consume small electric power electricity
Cable, and increase electro-magnetic screen layer 12 and make the utility model strong antijamming capability, and concentric type conductor 13 can a line two use, both
It can be used as conductor, can also be used as cable shield, make the electromagnetic effect smaller of outer bound pair electric wire, and be electromagnetically shielded by being arranged
Layer 12 and concentric type conductor 13 can effectively reduce interference of the external electromagnetic wave to electric wire so that instrument is in use more
Stablize, ensure that transmission quality.
Further, the winding of copper strips 14 is wrapped in outside concentric type conductor 13, can be further reduced external electromagnetic wave to electricity
The influence of line.
Further, electro-magnetic screen layer 12 is formed by annealing proof copper-wire braided, has good electromagnetism interference performance, effectively
Shielding rejection coefficient is improved, each quasi-instrument can be applied in the environment of electromagnetic wave complex jamming, external electromagnetic can be resisted
The interference of wave ensures that the various current signals of transmission are safe and stable and reliable, without generating distortion.
