Abstract
The invention provides a radio-frequency coaxial cable. The radio-frequency coaxial cable comprises an inner conductor, an insulation layer and an outer sheath from inside to outside. An integrally cladded conductive plastic outer conductor shield layer is arranged between the insulation layer and the outer sheath, and the conductive plastic outer conductor shield layer is of seamless tubular structure. The conductive plastic outer conductor shield layer integrally coats without seams, electromagnetic leakage is avoided, shield effect is good, no other external interference is caused during signal transmission, and the cable is high in safety and reliability. The conductive plastic outer conductor shield layer cladding by extrusion is firm and less deformable, and the cable has high tensile strength and curve performance. The radio-frequency coaxial cable in the design is simple in production process and low in manufacturing cost, and production efficiency can be greatly improved.
Description
Technical field
The invention belongs to field of cable technology, especially relate to a kind of radio frequency coaxial-cable.
Background technology
Radio frequency coaxial-cable of the prior art, the production of outer conductor mainly adopts oxygen-free copper to carry out the mode of production of welding, embossing is coated.But in actual manufacture process, due to copper strips oxidation, corrosion or a variety of causes such as forming frock die debugging is bad, the various serious quality problems such as frequent generation weld seam welds partially, solder skip, weld seam trachoma, due to the non-conductive gap that the discontinuous of shield and shield different piece junction are formed, capital produces electromagnetic leakage, have a strong impact on the shielding properties of cable, formed to the security reliability of cable and threaten greatly.In addition, such design complex manufacturing, manufacturing cost is high, and production efficiency is low.
Summary of the invention
In view of this, the present invention is intended to propose a kind of radio frequency coaxial-cable, and structure is simple, reasonable in design, be easy to produce, easy to use.
For achieving the above object, technical scheme of the present invention is achieved in that
A kind of radio frequency coaxial-cable, comprises the inner wire, insulating barrier and the oversheath that arrange from the inside to the outside; The conductive plastics outer conductor screen of integral coating is also provided with between described insulating barrier and oversheath.
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 conductive plastics outer conductor screen is seamless tubular structure.
Relative to prior art, a kind of radio frequency coaxial-cable of the present invention has following advantage:
1) conductive plastics outer conductor screen integral coating, does not have gap, can not produce electromagnetic leakage, and shield effectiveness is good, and in signals transmission, not by other external interference, cable security reliability is high.
2) the conductive plastics outer conductor screen that extrusion molding is coated is firm, not yielding, and cable has higher tensile strength and bending property.
3) the radio frequency coaxial-cable production technology of this design is comparatively simple, and low cost of manufacture, production efficiency can be improved greatly.
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-inner wire, 2-insulating barrier, 3-conductive plastics outer conductor screen, 4-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.
A kind of radio frequency coaxial-cable, as shown in Figure 1, comprises the inner wire 1, insulating barrier 2 and the oversheath 4 that arrange from the inside to the outside; The conductive plastics outer conductor screen 3 of integral coating is also provided with between described insulating barrier 2 and oversheath 4.
It should be noted that, conductive plastics outer conductor screen 3 utilizes extruder to adopt the mode of production of the type that extrudes, and does not thus have weld seam, and screen there will not be solder skip, the partially quality problems such as weldering and trachoma, and eliminating one welding embossing operation, cable shield effect is very good.
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 4 is outer protective polyethylene cover or LSOH anti-flaming oversheath.The sheath of respective material is selected according to different applying working conditions.
Wherein, described conductive plastics outer conductor screen 3 is seamless tubular structure, and do not have gap, can not produce electromagnetic leakage, shield effectiveness is good.
It should be noted that; in order to prevent damaging by external impacts in cable installation process; armour can be set between conductive plastics outer conductor screen 3 and oversheath 4; like this; even if accidentally cable cover(ing) is knocked against hard, cable collision or weigh wounded time; due to the protection of armour, insulating barrier 2, the inner wire 1 of conductive plastics outer conductor screen 3 and inside thereof all can not sustain damage, and more serious distortion can not occur and the situation that cannot use.
Conductive plastics outer conductor screen 3 integral coating of the present invention, in signals transmission, not by other external interference, cable security reliability is high.Meanwhile, conductive plastics outer conductor screen 3 comparatively robust that extrusion molding is coated, not yielding, cable has higher tensile strength and bending property.In addition, radio frequency coaxial-cable production technology provided by the invention is comparatively simple, and low cost of manufacture, production efficiency can be improved greatly.
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.
