Abstract
The invention provides a radio frequency coaxial cable with a compressive shielding function. The radio frequency coaxial cable comprises an inner conductor, an insulating layer, an outer conductor and an outer jacket which are arranged front inside to outside, a double-steel-belt armored layer is arranged between the outer conductor and the outer jacket, and the outer conductor is a seamless electroconductive plaster outer conductor. An outer conductor shielding layer integrally wrapped by electroconductive plastic is adopted and is seamless, thereby being free of electromagnetic leakage and good in shielding effect. In addition, the outer conductor shielding layer is not made by using a nonferrous metal material and replaces a lining layer of the steel-belt armored layer in the cable, so that manufacturing cost of the cable is lowered. The double-steel-belt wrapped armored layer is adopted, so that the cable is high in mechanical strength and bending performance, the compressive shielding function of the cable is enhanced, and service life of the cable is prolonged.
Description
Technical field
The invention belongs to field of cable technology, especially relate to a kind of radio frequency coaxial-cable with resistance to compression function of shielding.
Background technology
Coaxial cable is widely used in the wire transmission network systems such as cable TV transmission network network system, closed-circuit television system, supervisory control system, safety and protection system, it is as backbone, main line or service main, the information such as TV transmission image, sound, data, symbol, are also applied in the wire transmission network of other impedance matchings of similar applications.Along with the living standard of people improves constantly, for obtaining more real transmission information, also more and more higher to the requirement of coaxial cable.The deficiency of existing radio frequency coaxial-cable owing to existing by material and configuration aspects, when cable is used in the communications industry, its resistance to compression function of shielding is difficult to adapt to harsh instructions for use, and sensitive for damages causes communication failure.
Summary of the invention
In view of this, the present invention is intended to propose a kind of radio frequency coaxial-cable with resistance to compression function of shielding, and cable machinery intensity is high, good bending property, under being applicable to harsh service condition.
For achieving the above object, technical scheme of the present invention is achieved in that
There is a radio frequency coaxial-cable for resistance to compression function of shielding, comprise the inner wire, insulating barrier, outer conductor and the oversheath that arrange from inside to outside; Double-tape armor layer is also provided with between described outer conductor and oversheath; Described outer conductor is seamless conductive plastics outer conductor.
Further, described inner wire is oxygen-free copper conductor.
Further, described insulating barrier is the high density polyethylene (HDPE) foaming bed of material.
Further, described oversheath is outer protective polyethylene cover or LSOH anti-flaming oversheath.
Further, described double-tape armor layer is the zinc-plated pair of wrapped armour of steel band.
Further, described steel band wrapped gap≤width of steel band 45%.
Relative to prior art, a kind of radio frequency coaxial-cable with resistance to compression function of shielding of the present invention has following advantage:
1) adopt the outer conductor screen of conductive plastics integral coating not have gap, can not produce electromagnetic leakage, shield effectiveness is good.
2) outer conductor screen does not use nonferrous materials, and it instead of the inner covering of steel-tape armouring layer in cable, reduces the manufacturing cost of cable.
3) adopt two wrapped armour of steel band, cable machinery intensity is high, good bending property, strengthens the resistance to compression function of shielding of cable, extends the useful life of cable.
Accompanying drawing explanation
The accompanying drawing forming a part of the present invention is used to provide a further understanding of the present invention, and schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 is structural representation of the present invention.
Description of reference numerals:
1-conductor, 2-insulating barrier, 3-outer conductor, 4-double-tape armor layer, 5-oversheath.
Embodiment
It should be noted that, when not conflicting, the embodiment in the present invention and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
There is a radio frequency coaxial-cable for resistance to compression function of shielding, as shown in Figure 1, comprise the inner wire 1, insulating barrier 2, outer conductor 3 and the oversheath 5 that arrange from inside to outside; Double-tape armor layer 4 is also provided with between described outer conductor 3 and oversheath 5; Described outer conductor 3 is the conductive plastics outer conductor of seamless tubular structure.Outer conductor 3 is easy to processing, integral coating, seamless generation.
It should be noted that, outer conductor 3 utilizes extruder to adopt the mode of production of the type that extrudes, thus the outer conductor 3 as screen does not have gap, the solder skip occurred when solving outer conductor of the prior art welding, the partially quality problems such as weldering and trachoma, eliminate one welding embossing operation, cable shield effect is very good simultaneously.And outer conductor 1 does not use nonferrous materials, it instead of the inner covering of steel-tape armouring layer in prior art cable, reduces the manufacturing cost of cable.
Wherein, described inner wire 1 is oxygen-free copper conductor.Without Hydrogen Brittleness Phenomena, conductance is high, processing characteristics and welding performance, corrosion resisting property and cryogenic property all relatively good.
Wherein, described insulating barrier 2 is the high density polyethylene (HDPE) foaming bed of material, and insulation effect is good.
Wherein, described oversheath 5 is outer protective polyethylene cover or LSOH anti-flaming oversheath.The sheath of respective material is selected according to different applying working conditions.
At the wrapped zinc-plated double-tape armor layer 4 in left-hand gap, outer conductor 3 periphery, wrapped gap is not more than 45% of width of steel band, and extrudes one deck oversheath 5 outside double-tape armor layer 4.Like this, cable machinery intensity is high, good bending property, and resistance to compression function of shielding is superior, effectively can extend the useful life of cable.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
