Insulated wire cores 10 include the stranded conductor 101 of multi beam strand and the insulating barrier 102 being coated on outside conductor 101.
Strand using layer-stranding structure formed conductor 101, innermost layer be single strand, remainder layer by multi beam strand distinguish it is stranded
Form, last layer is closely enclosed in interior by each layer by innermost layer outwards.Except innermost layer, twist between adjacent layer to contrary.
But the cable of the structure has the following disadvantages：1st, the conductor of insulated wire cores is formed by strand layer-stranding, its
Middle outermost layer lay ratio is 14～16 times, and the lay ratio of other layers in addition to outermost layer and innermost layer is 16～19 times, insulation
It is 16～18 times that core is twisted into the lay ratio of cable core.Lay ratio is larger, causes the bending radius of conductor and cable core little, conductor and
The pliability of cable core can not meet cable frequently move, bend and resistance to torsion requirement.2nd, nonwoven layer is wrapped using eclipsed form
In cable core and holding wire are together coated on, the structure cable core can not be contacted with restrictive coating, cable when being frequently bended and reverse,
Each there is position movement with restrictive coating in cable core, cause cable to play bag, and conductor break, restrictive coating are damaged, and shorten making for cable
Use the life-span.3rd, the cross section of insulated wire cores is generally circular in cross section, then the gap between insulated wire cores is larger, existing packing material
For polyethylene rope, it is impossible to ensure the roundness of cable.
Utility model content

2nd, implant includes packing and aramid yarn, the diameter of packing and the equal diameters of insulated wire cores, and using close
Degree and hardness can increase the stability of the construction of cable, it is ensured that the rounding property of cable more than the TPE materials of aramid yarn.
3rd, compared to existing cable, electro-magnetic screen layer is increased, which includes plastic-aluminum belt and wrapped braiding thereon
Copper wire layer, enhances the electromagnetism interference of cable.The electric capacity that proof copper-wire braided layer grid element center is produced is disappeared by aluminum plastic belt major part
Remove, surface transfer impedance less than 10 (CQC standards are less than 250), cancel out each other by the magnetic field that both produce.
4th, it is in being together coated on cable core and holding wire using mylar tape and wrapped using eclipsed form, it is easy to cable
Core is tightened, it is ensured that the rounding property of cable, and in being also convenient for rear operation, cable core is combined closely with inner restrictive coating, facilitates charging pile cable
The joint of terminal.
5th, the conductor of insulated wire cores is formed by strand layer-stranding, and each layer of remaining in addition to innermost layer is twisted to identical, soft
Soft to get a promotion, up to 5D (D is finished cable diameter), the stranded lay ratio of each layer of remaining in addition to innermost layer is bending radius
8～10 times, it is 12～14 times that insulated wire cores are twisted into the lay ratio of cable core, and compared with existing cable, lay ratio reduces, bending
Radius further reduces.
