, it is necessary to explanation, unless otherwise clearly defined and limited, term " is pacified in the description of the invention Dress ", " connected ", " connection " should be interpreted broadly, for example, it may be fixedly connected, or be detachably connected, or integratedly Connection；Can mechanically connect, or electrically connect；Can be joined directly together, it is also possible to be indirectly connected to by intermediary, Can be two connections of element internal.For the ordinary skill in the art, can be by concrete condition understanding State concrete meaning of the term in the invention.
Describe the invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
A kind of Aviation cable, as shown in figure 1, the vertical bag screen layer of copper strips embossing coated successively including cable core and cable core outside 8 and oversheath 9；The cable core includes that at least one line, to 1, the He of woven shield 5 is coated with to outside in each line successively Inner sheath 6；The line is to including mutually stranded two single lines 2, and it is exhausted that every single line includes that copper conductor 3 and its outside coat Edge layer 4；At least one drainage thread 7 is provided between the inner sheath and the vertical bag screen layer of copper strips embossing.In addition, in order to improve electricity The mechanical strength of cable, can set glass fibre reinforcer in cable core, effectively increase the ability that cable tension is dragged.Above-mentioned volume Screen layer 5 is knitted for copper wire or tinned copper wire woven shield.
It should be noted that compared to prior art, this Aviation cable is provided with drainage thread 7, and drainage thread is arranged on Between inner sheath and the vertical bag screen layer of copper strips embossing, it can be ensured that copper strip shielding layer is remained after laying and in long-term use Excellent interference free performance, meets bonding requirement.
It is pointed out that being coated on cable core outside using the vertical bag screen layer 8 of copper strips embossing, cable can be effectively improved anti- Toughness is not enough during multiple bending, laying installation, the problems such as screen layer is easily broken.The vertical bag screen layer of copper strips embossing can strengthen cable Shielding properties, it is ensured that stable signal transmission is undistorted.
Above-mentioned insulating barrier 4 is three-layer co-extruded skin-bubble-skin physical foam insulation.Insulating resistance of cable can be improved, electricity is reduced The sending allowance of cable, reduces the mutual capacitance of cable, so as to the reliability for greatly improving the security of cable and use.
It is pointed out that the internal single line of line is mutually stranded, it is preferred that the twisting pitch≤300mm of line centering single line, The line pair of twisting pitch in the range of this is made, the indexs such as cross-talk, the decay of cable can be effectively improved, improve the items electricity of cable Gas performance.Above-mentioned cable core uses at least one line pair, when cable core includes two and more than two lines pair, phase between each line pair Mutual stranded setting.
Because Aviation cable has harsher requirement to the properties of cable, therefore, above-mentioned inner sheath and oversheath Preferably both use fluorocarbon resin oversheath, it is ensured that cable has the performance such as heat-resisting, cold-resistant, chemicals-resistant, adapt to harsh operating mode, Effectively extend the service life of cable, current Aviation cable has also been short of in this.Furthermore it is also possible in oversheath Inner side sets one layer of fireprotection layer, to improve fireproofing of cable performance.
For the shielding properties for ensuring cable is excellent, copper wire that above-mentioned woven shield is used or tinned copper wire diameter should >= 0.1mm, and braiding tight ness rating answers >=85%.
When this cable makes：
First two insulated single wires of different colours are carried out being made by twisting line pair；Then copper is externally selected in stranded complete line Silk or tinned copper wire and use weaving one layer of woven shield 5 of braiding；
One layer of inner sheath 6 is extruded outside woven shield 5 afterwards, using the vertical bag equipment of embossing outside inner sheath 6, cladding one The vertical bag screen layer 8 of layer copper strips embossing.
Draw earial drainage line 7 at least provided with one between inner sheath 6 and the vertical bag screen layer 8 of copper strips embossing afterwards, finally in copper One layer of oversheath is extruded outside the vertical bag screen layer 8 of band embossing.
This Aviation cable has the performances, long service life, good operating stability such as heat-resisting, cold-resistant, chemicals-resistant corrosion.Its In, it is individually shielded to carrying out to each line using copper wire or tinned copper wire braiding, the shielding properties and mechanical-physical of cable can be improved Performance, reduces line signal between and interferes.
The preferred embodiment of the invention is the foregoing is only, creation is not intended to limit the invention, it is all at this Within the spirit and principle of innovation and creation, any modification, equivalent substitution and improvements made etc. should be included in the invention Protection domain within.
