Description
Technical field
The invention belongs to communication cable technical fields, are related to a kind of steady phase radio-frequency cable.
Background technology
In the radio frequency communications field, the interconnection line of equipment room is more and more, and in order to integrate various cables
Classification connects, and is usually condensed together by way of various cable products twisted synthesizing cables in industry.
A kind of equidirectional twisted control cable is disclosed through retrieval, such as Chinese patent literature【The patent No.：ZL
201510322599.5；Authorization Notice No.：CN 106298052A】.This equidirectional twisted control cable, including conductor, it is interior absolutely
Edge layer, shielded layer, external insulation layer, tensile cord and filler；Inner insulating layer is wrapped up in the conductor outer layer, outside inner insulating layer
Layer provided with shielding layer sets a plurality of tensile cord twisted at counter clockwise direction in shielded layer peripheral hardware external insulation layer in external insulation layer；?
Filler is set between conductor and inner insulating layer；The conductor is no less than 2, and direction of lay is identical as tensile cord direction of lay.
This equidirectional twisted control cable does comprehensive conductor, and peripheral hardware external insulation layer after being twisted together with filler using 3 groups of conductors
And shielded layer, there is good audio-video signal delivery safety, reduce interference.
And for steady phase radio-frequency cable, because of its high-speed, low decaying and the requirement of phase stability, pass through strand
Closing this mode can make the medium of phase-compensated cable generate slight deformation and distortion, and then influence the table of its various electric property
It is existing；If stranding distance very little, and twisted tension force is improper, can make phase-compensated cable medium injured if serious, and standing wave generates peak value.
In order to solve this problem, we are designed as similar products flat structure, keep each section cable products parallel
It is layered on together, then squeezes out that oversheath is fixed-type by them, eliminate the twisted injury to cable, ensure that each of phase-compensated cable
Kind performance.
Through retrieval, as Chinese patent literature discloses a kind of flat cable【The patent No.：ZL201620712847.7；It authorizes
Notification number：CN 205827958U】.This flat cable includes sheath, be provided in the sheath linearly arrangement and
Away from three groups of equal cable core units, the cable core unit includes conductor, the insulating layer that is wrapped on conductor, is wrapped in insulating layer
On wrapping layer and the flame-retardant layer that is wrapped in wrapping layer.Flat cable can be made by rational structure and the type selecting of material
There are the flat cable performances such as its acid and alkali-resistance, high temperature resistant, resistance to resistance to compression to be promoted by a relatively large margin.
But above-mentioned flat cable generally existing signal integrity difference and the not high deficiency of flex life.So right
In those skilled in the art, it need to be improved flat cable in the prior art, so that the performance of flat cable
It is more superior.
Invention content
The purpose of the present invention is there is the above problem in view of the prior art, it is proposed that a kind of steady phase radio-frequency cable, this hair
It is bright to have the characteristics that signal integrity is good and flex life is high.
Object of the invention can be realized by the following technical scheme：A kind of steady phase radio-frequency cable, including several parallel set
The radio frequency phase-compensated cable line set, several radio frequency phase-compensated cable lines are coated with oversheath, which is characterized in that are set in the oversheath
There are power cord or signal wire or reinforcement lifting-line, power cord or signal wire or reinforce lifting-line and is in the radio frequency phase-compensated cable line
Lineal layout, the spacing between the adjacent radio frequency phase-compensated cable line is equal, power cord or signal wire or reinforce lifting-line with
Spacing between any radio frequency phase-compensated cable line is all higher than the spacing between adjacent radio frequency phase-compensated cable line.
This steady phase radio-frequency cable:1, since radio frequency phase-compensated cable line is parallel lay-up in oversheath, not by squeezing
The injury of pressure or distortion, so the electric property of radio frequency phase-compensated cable line is not interfered by process structure, therefore signal
Integrality is good.2, steady phase radio-frequency cable can arbitrarily be repeated as many times along the band-like plane of cable and be bent, will not without damaging cable
It is deformed, therefore, flex life is high.
In above-mentioned steady phase radio-frequency cable, metal screen layer is provided on the outside of the radio frequency phase-compensated cable line.
In above-mentioned steady phase radio-frequency cable, the metal screen layer is the flat copper sheet of two panels.
In above-mentioned steady phase radio-frequency cable, filler is equipped between the oversheath and radio frequency phase-compensated cable line.
In above-mentioned steady phase radio-frequency cable, the radio frequency phase-compensated cable line includes conductor, insulation successively from inside to outside
Layer, conductor shield and inner sheath.
In above-mentioned steady phase radio-frequency cable, the material of the conductor is aluminium alloy or tin-coated copper.
In above-mentioned steady phase radio-frequency cable, the conductor shield is web.
In above-mentioned steady phase radio-frequency cable, the insulating layer, filler, inner sheath and oversheath are the poly- second of crosslinking
Alkene.
In above-mentioned steady phase radio-frequency cable, the quantity of the radio frequency phase-compensated cable line is 2-10 roots.
Compared with prior art, the present invention has the following advantages：
1, the present invention is not squeezed or distorts since radio frequency phase-compensated cable line is parallel lay-up in oversheath
Injury, so the electric property of radio frequency phase-compensated cable line is not interfered by process structure and single test when does not have
There is difference, and this structure of parallel lay-up significantly improves the tensile property of product.
2, stranding twisted process has been lacked when present invention production, has been directly that more radio frequencies are steady by outermost oversheath
Phase cable parallel cluster is twisted this procedure to stranding together, has been lacked, and eliminates the additional cable generated because being twisted coefficient
Dosage more saves material.
3, the present invention is compared with the cable of lay configuration, the finished cable of same length, and signal is parallel in transmission process
The actual signal transmission range of structure can be less than lay configuration.
4, the present invention can arbitrarily be repeated as many times along the band-like plane of cable and be bent, and without damaging cable, will not generate change
Shape, flex life are high.
