Description
Technical field
The utility model is related to a kind of coaxial cables, specifically salt spray proof superhigh shielded radio frequency coaxial-cable.
Background technology
In the transmission networks such as existing cable television system, video monitoring system, the radio frequency coaxial-cable of use is generally adopted
With common interior thin layer technique, interior thin layer is made of low-density Insulation Material with sizing, it is difficult to play the effect of salt spray proof；And outer shield
Between set and outer conductor, handle without special process, had the gap between each layer structure.On some regional (such as islands), because of place
In the heavier marine climate environment of the environment that humidity is larger, particularly salt fog, salt fog, steam easily enter inside cable, cause
Cable outer conductor aoxidizes, and influences cable transmission performance and service life.In addition, generic coaxial cable is using general aluminium
Foil, count is 60% or so, it is difficult to repeatedly bending, and shield effectiveness can only achieve 70dB.And in electromagnetic interference day
The serious outdoor environment of benefit, is highly prone to the influence of other noises, has seriously affected the final visual/audio effects of cable.
Utility model content
The purpose of the utility model is to overcome the deficiencies of above-mentioned background technology, and it is same to provide a kind of salt spray proof superhigh shielded radio frequency
Shaft cable, the coaxial cable can be applied to the particular surroundings such as concentration of saline fog is big, moisture is big, interference signal is more.
The utility model provides following technical scheme：
Salt spray proof superhigh shielded radio frequency coaxial-cable includes inner wire, high-foaming insulating layer, thickeies certainly successively from inside to outside
Viscous aluminium foil, braiding layer, the double-sided self-adhesive aluminum foil for being coated on braiding layer surface and extrusion molding are in the outer shield of double-sided self-adhesive aluminum foil outer surface
Set；It is characterized in that：The inner wire surface uniformly extrudes one layer of salt spray proof interior thin layer for preventing inner wire from aoxidizing；It is described
Even application is useful for the salt spray proof oil of isolation steam and salt fog between braiding layer and double-sided self-adhesive aluminum foil.
The high-foaming insulating layer outer rim also extrudes one layer of salt spray proof outer thin layer, prevents steam and salt fog from penetrating into insulating layer.
The thickness for thickening self-adhesion aluminium foil and double-sided self-adhesive aluminum foil is more than 9 μm.
The braiding layer material is aluminum-magnesium alloy wire that tensile strength is more than 300MPa, the count of the braiding layer
It is more than 80%.
The jacket material is the polyvinyl chloride of antiultraviolet.
The beneficial effects of the utility model are：
Being extruded in the salt spray proof interior thin layer on inner wire surface can effectively prevent inner wire to aoxidize.Meanwhile braiding layer with
Sprayed between double-sided self-adhesive aluminum foil salt spray proof oil, can completely cut off completely steam, salt fog to braiding layer outer conductor (i.e. braiding layer and
Double-sided self-adhesive aluminum foil) erosion, prevent braiding layer outer conductor surface oxidation.In addition, thickening self-adhesion aluminium foil and double-sided aluminum foil are adopted
It with thickening type aluminium foil, can both increase the mechanical strength and bending property of cable, the shield effectiveness of cable can also be effectively improved,
Extend service life of the cable in various adverse circumstances.
Description of the drawings
Fig. 1 is the main structure diagram of the utility model.
Specific embodiment
With reference to the accompanying drawings of the specification, the utility model is described in further detail, but the utility model be not limited to
Lower embodiment.
It is exhausted to include inner wire 1, high-foaming successively from inside to outside for salt spray proof superhigh shielded radio frequency coaxial-cable as depicted
Edge layer 3 thickeies self-adhesion aluminium foil 4, braiding layer 5, double-sided aluminum foil 7 and oversheath 8.These are similar with normal cable.
The improvement of the utility model is as follows：
The inner wire surface is uniformly extruded with one layer of salt spray proof interior thin layer 2 for preventing inner wire from aoxidizing.In physics
In high-foaming insulation extrusion process, by proportioned internal layer salt spray proof material, uniformly, densely extrude in the conductor, by
Conductor deadend is got up, and is formed one layer of closely knit salt spray proof interior thin layer in interior conductive surface, inner wire can be effectively prevent to aoxidize.
In addition, three-layer co-extruded mode also can be used, increase by one layer of salt spray proof outer thin layer (figure is extruded in the outer surface of high-foaming insulating layer
In do not show), prevent steam and salt fog from penetrating into insulating layer, improve resistance to compression, the tensile strength of insulating layer.
The thickening self-adhesion aluminium foil and double-sided aluminum foil can increase mechanical strength and the bending of cable using thickening type aluminium foil
Performance, even across the bend test of 10000 times or more, deterioration performance is also no more than 10%；Cable can also be effectively improved
Shield effectiveness, shielding attenuation substantially increases service life of the cable in various adverse circumstances up to more than 90dB.Production
When, aluminium foil cannot wrinkle, can pass through the stock mould of design, it is ensured that the forming rounding of reinforced aluminium foil ensures aluminium foil after finished product
Bending effect.
The braiding layer uses the aluminum-magnesium alloy wire of more than tensile strength 300MPa, and count is more than 80%.It is described
Even application has salt spray proof oil 6 between braiding layer and double-sided aluminum foil.During production, first salt spray proof oil is matched, is filled by spraying
Put, equably spray salt spray proof oil on braiding layer outer conductor, formed one layer prevent steam, salt fog erosion protective layer.So
One layer of double-sided self-adhesive aluminum foil (thickness of the double-sided self-adhesive aluminum foil is coated by finishing die, positioning mould again in braiding layer surface afterwards
It is preferred that 9 μm or more), finally outer shield is formed in the pvc sheathing compound of double-sided self-adhesive aluminum foil outer surface one layer of antiultraviolet of extrusion molding
Set.By high temperature, double-sided self-adhesive aluminum foil is made to be bonded together with oversheath.Can effectively it be pressed down using antiultraviolet pvc material
Intensive ultraviolet processed improves the service life of cable to the aging action of oversheath.
Finally it should be noted that listed above is only specific embodiment of the utility model.Obviously, this practicality is new
Type is not limited to above example, can also there is many variations.Those of ordinary skill in the art can be from disclosed in the utility model
All deformations for directly exporting or associating in content, are considered as the scope of protection of the utility model.
