The two-channel transmission radio-frequency cable comprises a first center conductor, a first medium layer, a first inner shielding layer, a second center conductor, a second medium layer and the second inner shielding layer, wherein the first medium layer wraps the first center conductor, the first inner shielding layer wraps the first medium layer, the second center conductor wraps the first inner shielding layer, the second medium layer wraps the second center conductor, and the second inner shielding layer wraps the second medium layer. By designing two center conductors, and one circuit is formed with the corresponding shielding layers according to skin effect of current, so that two-channel signal transmission of the cable is realized.
Description
[technical field]
The present invention relates to coaxial cable technology field, relate in particular to a kind of radio frequency coaxial-cable of realizing double-channel signal transmission.
[background technology]
All can only realize single channel transmission at most in the market radio frequency cables, as disclosed in Chinese patent CN201020689308.9 " a kind of low loss coaxial radio frequency cable ", inner wire and compound outer conductor can only form an information circuits.If many signals parallel transmission, just often simply smoothing out with the fingers multiple cables is held together, becoming composite cable uses, this as disclosed in Chinese patent CN201020554412.7 " composite cable ", the multiple cables that wrap up in this composite cable are non-coaxial, therefore signal easily interacts, and in the middle of whole cable, space is large, so that entirety takes up room more.Some special occasions need to be used the radio frequency cable that can realize binary channels transmission, and these technology all rest in the hand of some foreign enterprises, and this has directly affected the development in the fields such as domestic communication, Aeronautics and Astronautics, aerospace.
Therefore, be necessary to provide a kind of binary channels radio frequency cable to solve the problems referred to above.
[summary of the invention]
Main purpose of the present invention is to provide a kind of radio frequency coaxial-cable of realizing double-channel signal transmission.
For achieving the above object, the present invention can adopt following technical scheme: a kind of binary channels transmission radio frequency cable, comprises the first center conductor, is wrapped in first medium layer outside described the first center conductor, is wrapped in the first internal shield outside described first medium layer, is wrapped in the second center conductor outside described the first internal shield, is wrapped in the second medium layer outside described the second center conductor and is wrapped in the secondary shielding layer of described second medium layer.
Preferably, described the first center conductor and described the first internal shield form the first loop.
Preferably, described the second center conductor and described the second internal shield form second servo loop.
In some embodiments, described the first center conductor and the second center conductor layer form by silver-plated copper is stranded.
In some embodiments, described first medium layer and second medium layer form by teflin tape is wrapped.
In some embodiments, described the first internal shield and the second internal shield are formed by silver-plated copper strips braiding.
Preferably, described the first internal shield and the second internal shield are formed by silver-plated copper strips braiding.
Preferably, described the second internal shield is wrapped with aluminium foil layer, and described aluminium foil layer is wrapped with outer shielding layer.
In some embodiments, described outer shielding layer is formed by silver-gilt copper wire braiding.
Preferably, described outer shielding layer is wrapped with sheath.
In some embodiments, described sheath is formed by PUR material hot-melt extruded.
Compared with prior art, the beneficial effect of binary channels transmission radio frequency cable of the present invention is:
1, except the first center conductor and the first internal shield form first galvanic circle, the second center conductor and the second internal shield form second galvanic circle, realize twin-channel signal transmission.
2, due to electromagnetic kelvin effect, electric current can transmit on the first center conductor and the second center conductor, and the first screen and secondary shielding layer have formed good shield effectiveness or loop effect; And braid packed density is less, when being provided, outer support alleviate the cable weight of unit length.
3, the first center conductor and the second center conductor layer are all to form by silver-plated copper is stranded, make cable comparatively soft.
4, aluminium foil layer has good conductivity, weaves the external shield forming form two-layer shielding construction with silver-gilt copper wire, can disturb to external world and play good isolation effect.
5, protective sleeve is not worn for the protection of outer shielding layer, extends the useful life of cable.
[brief description of the drawings]
Fig. 1 is the structural representation of binary channels transmission radio frequency cable of the present invention.
In figure: 1, the first loop, 11, the first center conductor, 12, first medium layer, 13, the first internal shield, 2, second servo loop, 21, the second center conductor, 22, second medium layer, 23, the second internal shield, 3, aluminium foil layer, 4, outer shielding layer, 5, sheath.
[embodiment]
As shown in Figure 1, the present invention is a kind of binary channels transmission radio frequency cable, comprise the first center conductor 11, be wrapped in first medium layer 12 outside the first center conductor 11, be wrapped in the second inner shield 13 outside first medium layer 12, be wrapped in the second center conductor 21 outside the second internal shield 13, be wrapped in second medium layer 22 outside the second center conductor 21, be wrapped in the second internal shield 23 outside second medium layer 22, be wrapped in the aluminium foil layer 3 outside the second internal shield 23, be wrapped in the outer shielding layer 4 outside aluminium foil layer 3, be wrapped in the sheath 5 outside outer shielding layer 4.
First center conductor 11 forms by silver-plated copper is stranded, then the first medium layer 12 forming at the outer wrapped teflin tape of the first center conductor 11, first medium layer 12 is outer forms the first internal shield 13 with silver-plated copper strips braiding, the first center conductor 11 and the first internal shield 13 are by first medium layer 12 isolation of insulating, the first loop 1 that is configured for sending and accepting the signal of telecommunication, stranded the first center conductor 11 forming can make cable more soft.
The second center conductor 21 is formed in the outer braiding of the first internal shield 13 by silver-plated copper twisted wire, the second medium layer 22 that the outer wrapped teflin tape of the second center conductor layer 21 forms, second medium layer 22 is outer forms the second internal shield 23 with silver-plated copper strips braiding, the second center conductor 21 and the second internal shield 23 are by second medium layer 22 isolation of insulating, the second servo loop 2 that is configured for sending and accepting the signal of telecommunication, stranded the second center conductor 21 forming can make cable more soft.
Aluminium foil layer 3 is by aluminium foil strip outer wrapped the forming of the second internal shield 13, and aluminium foil layer 3 is outer to be woven outside and form outer shielding layer 4 with silver-gilt copper wire again.Through above double-layer structure, interference signal plays better shielding action to external world.
The last outer shielding layer completing in braiding 4 peripheries form sheath 5 with PUR material hot-melt extruded.Sheath 5 can prevent outer shielding layer 4 wear and rupture that form of braiding, extends cable useful life.
