Abstract
The invention discloses a stable phase cable high in mechanical phase stability. A silver-plated copper conductor is arranged in the center of the cable, and a teflon foam insulation layer is extruded outside the silver-plated copper conductor in a stretching mode. A silver-plated copper strip outer conductor is wound around the outer layer of the teflon foam insulation layer. A silver-plated copper wire shielding layer is woven outside the silver-plated copper strip outer conductor. The silver-plated copper wire shielding layer is wrapped in a polyperfluorinated ethylene-propylene sheath layer in an extruded mode. While other electric properties and mechanical property indexes are met, the stable phase cable is further high in mechanical phase stability, good in temperature phase stability and high temperature and low temperature resistance and high in anti-interference capacity.
Description
technical field
Patent of the present invention relates to a kind of high mechanical phase stable type phase-compensated cable, the signal transmssion line that this cable mainly has phase sensitivity to require as phased array radar, EW Equipment etc.
background technology
Development along with weaponry systems technologies such as the monitoring of early warning plane phased array radar, electronic counter-measures equipment, satellite and guided missile and other digital phase sensitive electronic systems, the transmission frequency of radio frequency cable, loss and phase stability have been proposed to new requirement, and the mobile field radar that particularly needs repeatedly to move use is higher for the mechanical phase stability requirement of phase-compensated cable.This has just caused the research of people to cable temperature phase place and mechanical phase and material and manufacture craft relation.According to the variation of teflon insulation dielectric constant with temperature and conductor mechanical length, with change of shape, cause the variation of cable machinery phase place to cancel out each other, by designing good structure and technology controlling and process, can make the mechanical phase variation coefficient of cable reach minimum.
Summary of the invention
The blank needing for filling up above field, patent of the present invention provides a kind of high mechanical phase stable type phase-compensated cable, when meeting other electrical property and mechanical performance index requirement, also there is high mechanical phase stability, good temperature phase stability, resistant of high or low temperature and stronger antijamming capability.
The solution of the present invention is as follows: a kind of high mechanical phase stable type phase-compensated cable, the center of cable is provided with silver-plated copper conductor, in the out-draw of silver-plated copper conductor, extrude polytetrafluoroethylene fluid insulation, at the silver-plated copper strips outer conductor of the outer winding of polytetrafluoroethylene fluid insulation, at silver-plated copper strips outer conductor, weave one deck silver-coated copper wire screen outward, at silver-coated copper wire screen, extrude perfluoroethylene-propylene restrictive coating outward.
Beneficial effect of the present invention:
1, mechanical phase stability is high: by the insulation of stretched polytetrafluoroethylene exruded foams and silver-plated flat copper band, be wound around outer conductor, make between stretched polytetrafluoroethylene cellular insulation and inner wire tightr, when bending, be not easy to occur relative displacement, thereby guaranteed the mechanical phase of cable, meeting low-loss while of cable, make that the mechanical phase of phase-compensated cable is minimum reaches 4.21 °/26.5GHz, much smaller than 13.25 °/26.5GHz of traditional structure.
2, operating temperature range is wide: on material is selected, inner wire adopts silver-coated copper wire, and insulation adopts the polytetrafluoroethylene foam of 250 ℃ of heatproofs, and outer conductor adopts silver-plated flat copper band, and screen adopts silver-coated copper wire, and sheath adopts the perfluoroethylene third of 200 ℃ of heatproofs rare.Cable all adopts exotic material, and the long-term serviceability temperature of cable, at-65-200 ℃, has improved the environment for use temperature range of cable, is suitable for using in adverse circumstances.
accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Number in the figure: 1 silver-plated copper conductor, 2 polytetrafluoroethylene cellular insulations, 3 silver-plated copper strips are wound around, 4 silver-bearing copper line shieldings, 5 perfluoroethylene-propylene restrictive coatings.
embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
The center of the cable of the present embodiment is provided with silver-plated copper conductor 1, in 1 out-draw of silver-plated copper conductor, extrude polytetrafluoroethylene fluid insulation 2, at the silver-plated copper strips outer conductor 3 of polytetrafluoroethylene fluid insulation 2 outer winding, at the outer braiding one deck of silver-plated copper strips outer conductor 3 silver-coated copper wire screen 4, outside silver-coated copper wire screen 4, extrude perfluoroethylene-propylene restrictive coating 5, final finished.
Although above the specific embodiment of the present invention has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present invention and change and revise; when its function producing does not exceed spiritual that specification contains yet, all should be within protection scope of the present invention.
