Description
Technical field
The utility model is related to the technical field of coaxial cable, more particularly to a kind of high shielding low noise coaxial cable.
Background technology
With the fast development of economic society, DTV comes into huge numbers of families.It is usually used coaxial on the market
Cable is usually to be made of inner wire, insulating layer, outer conductor shielded layer plastic composite strip and copper wire braid and insulating sheath.But
It is that existing coaxial cable is in use, transmission signal can be by two defects：1. shield effectiveness is undesirable, in some signal sources
More occasions, transmission signal are easily interfered, and signal are caused significantly to be distorted, shield effectiveness only has 75db；2. transmit signal
Noise can be generated, and noise can increase with increasing for signal transmission frequencies, terminal device can be largely effected on and receive signal frequency
Rate effect.
Utility model content
Technical problem to be solved in the utility model be overcome the deficiencies of the prior art and provide it is a kind of it is simple in structure,
The high shielding low noise coaxial cable that shield effectiveness is high, transmitted noise is small.
Technical solution is used by the utility model：The utility model includes conductor layer and is coated on successively from inside to outside
Insulating layer, outer conductor shielded layer and insulating sheath outside the conductor layer, the insulating layer and the outer conductor shielded layer it
Between be provided with a ultra-thin conductive PVC shielded layers, be provided with a noise between the outer conductor shielded layer and the insulating sheath
Separation layer.
Further, the thickness of the ultra-thin conductive PVC shielded layers is 0.1mm.
Further, the ultra-thin conductive PVC shielded layers are made of macromolecule modified material.
Further, the sound insulating layer is cotton paper.
Further, the conductor layer is twisted for a round copper wire or by more round copper wire.
Further, the insulating layer is made of the foaming of PE Material Physics.
Further, the outer conductor shielded layer is made of aluminium-plastic tape and copper wire braid.
Further, the insulating sheath is made of PCV materials.
The beneficial effects of the utility model are：Since the utility model includes conductor layer and is coated on institute successively from inside to outside
Insulating layer, outer conductor shielded layer and the insulating sheath outside conductor layer are stated, between the insulating layer and the outer conductor shielded layer
Be provided with a ultra-thin conductive PVC shielded layers, be provided between the outer conductor shielded layer and the insulating sheath noise every
Absciss layer, so, the utility model substantially increases shield effectiveness, more and more in signal source, the society more than outside electromagnetic interference
It, still being capable of normal use under environment；Shielding attenuation effect is good, and the high-frequency signal of transmission is made to leak small, improves high-frequency transmission
The energy of signal improves the transmission quality and transmission range of signal；Noise jamming is reduced, meets silencing equipment use.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
As shown in Figure 1, in the present embodiment, the utility model includes conductor layer 1 and is coated on successively from inside to outside described
Insulating layer 2, outer conductor shielded layer 4 and insulating sheath 6 outside conductor layer 1, in the insulating layer 2 and the outer conductor shielded layer 4
Between be provided with a ultra-thin conductive PVC shielded layers 3, be provided with one between the outer conductor shielded layer 4 and the insulating sheath 6
Sound insulating layer 5.In this design, the ultra-thin conductive PVC shielded layers 3 have good shield effectiveness, and shield effectiveness can reach
120db is that the shield effectiveness of coaxial cable entirety greatly improves, so as to ensure that coaxial cable transmits signal not by external electromagnetic wave
Influence, shielding attenuation effect is good, and the high-frequency signal of transmission is made to leak small, the energy of high frequency transmission signal is improved, improves
The transmission quality and transmission range of signal；The sound insulating layer 5 can adsorb noise and insulating noise in signal transmission,
So as to which coaxial cable be made to can be applied in silencing equipment.
In the present embodiment, the thickness of the ultra-thin conductive PVC shielded layers 3 is 0.1mm, and ultra-thin thickness will not increase together
The overall dimensions of shaft cable greatly improve the cost performance of cable.
In the present embodiment, the ultra-thin conductive PVC shielded layers 3 are made of macromolecule modified material, wherein containing uniform
Metal component, the shield effectiveness of ultra-thin conductive PVC shielded layers 3 is substantially increased, so as to imitate the shielding of coaxial cable entirety
It can greatly improve.
In the present embodiment, the sound insulating layer 5 is cotton paper, and cotton has good dependency and flexibility, believing
Number transmission when can adsorb noise and insulating noise.
In the present embodiment, according to field of employment, condition, the conductor layer 1 is a round copper wire, the circle copper wire
Material be fine copper.
In the present embodiment, the insulating layer 2 is made of the foaming of PE Material Physics.
In the present embodiment, the outer conductor shielded layer 4 is made of aluminium-plastic tape and copper wire braid, can be shielded outer
Interference of boundary's electromagnetic wave to signal transmission.
In the present embodiment, the insulating sheath 6 is made of PCV materials, and the insulating sheath 6 plays insulation protection work
With.
The utility model is applied to the technical field of coaxial cable.
Although the embodiment of the utility model is described with practical solution, do not form the utility model is contained
The limitation of justice, for those skilled in the art, according to group of this specification to the modification of its embodiment and with other schemes
Conjunction will be apparent from.
