Description
Technical field
The utility model belongs to coaxial cable field, more particularly, to a kind of low-noise coaxial cable.
Background technique
Existing coaxial cable product has formed complete process flow, and has opposite national standard, makes in fixation
Used time can be good at transmitting electromagnetic signal, but when cable is when vibrating, rocking, distort, can generate signal interference；Especially
The coaxial cable for range signal transmission used when for measuring bridge, Important building, because of vibration in use
Or swing, signal interference can be generated.
Summary of the invention
In view of this, the utility model is directed to a kind of low-noise coaxial cable, it is suitable for measurement bridge, important
Building etc. has the transmission of the signal of vibration or swing in use.
In order to achieve the above objectives, technical solution used by the utility model is a kind of low-noise coaxial cable, packet
The inner conductor of coaxial package, insulating layer, outer conductor and sheath from the inside to the outside are included, the inner conductor is made of copper wire material, inside leads
External cladding insulating layer, the insulating layer outer surface are uniformly coated with semiconductor graphite paint layer, semiconductor graphite paint layer outer cladding
Outer conductor is made of copper wire woven material.
Preferably, the semiconductor graphite paint layer is uniformly applied to insulating layer outer surface in insulation extrusion simultaneously.
Preferably, the insulating layer is made of polythene material.
Preferably, the sheath of the outer conductor outer cladding is made of pvc material.
Compared with the existing technology, the utility model has the advantage that
(1) by being coated with the processing of semiconductor graphite paint layer to insulating layer outer surface, make coaxial cable insulating layer in vibration
Outer surface uniform electromagnetic field distribution, so that coaxial cable be effectively reduced in vibration because the interference that coaxial cable itself generates is believed
Number.
(2) semiconductor graphite paint layer is uniformly applied to insulating layer outer surface simultaneously in insulation extrusion, so that semiconductor graphite
Paint layer is more uniform, is closely set to insulating layer outer surface, so that magnetic distribution is more uniform, further decreases coaxial cable
In vibration because of the interference signal of coaxial cable itself generation.
Detailed description of the invention
In attached drawing:
Fig. 1 is the embodiments of the present invention overall structure diagram；
Fig. 2 is the integrally-built schematic cross-section of the embodiments of the present invention；
Description of symbols:
1- inside conductor；2- insulating layer；3- semiconductor graphite paint layer；4- outer conductor；5- sheath.
Specific embodiment
Technical solution adopted by the utility model: as shown in Figure 1, 2, a kind of low-noise coaxial cable, including by
Inner conductor 1, insulating layer 2, outer conductor 4 and the sheath 5 of interior to outer coaxial package, the inner conductor 1 are made of copper wire material, inside lead
1 outsourcing insulating layer coating 2 of body, 2 outer surface of insulating layer are uniformly coated with semiconductor graphite paint layer 3,3 outsourcing of semiconductor graphite paint layer
The outer conductor 4 covered is made of copper wire woven material.
The semiconductor graphite paint layer 3 squeezes out in insulating layer 2 and is uniformly applied to insulating layer outer surface simultaneously.
The insulating layer 2 is made of polythene material.
The sheath 5 of 4 outer cladding of outer conductor is made of pvc material.
The working principle of the utility model is: coaxial cable is in signals transmission, because of the shaking of coaxial cable itself
The electromagnetic signal of generation generates the original of vibration interference signal by analysis cable to the interference problem for transmitting electromagnetic signal needed for it
Cause carries out graphitization processing to insulating surface, makes cable in vibration when conductor insulation is squeezed out, surface uniform electromagnetic field point
Cloth, so that the cable interference signal that cable itself generates in vibration be effectively reduced.
The coaxial cable of the utility model is detected and used through user, very satisfied to the performance of product, is actually using
In can be effectively reduced cable vibration when cable itself generate interference signal；The coaxial cable of the utility model is suitable for
Signal transmission in the case where having vibration in use process or swinging, especially can be used as special when measuring bridge, Important building
Coaxial cable.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
