Description
Technical field
The present invention relates to a kind of cable, particularly a kind of electric car conduction charging system cable.
Background technology
A kind of novel cable form that electric car conduction charging system cable is as electric automobile and occurs, it
For the charging connection of electric automobile Yu power supply, it is one of the key equipment of electric car conduction charging system, this series products
The good and bad safe and reliable operation on electric automobile of performance will produce directly impact.
Such cable can use at indoor or outdoors, should meet high and cold, daylight, rainwater and gasoline when outdoor application
The erosion of class material, this just requires that cable possesses and is suitable for use with the uvioresistant of occasion, ozone, high-low temperature resistant and chemical erosion
Etc. property.It in use by stretch bending frequently or can be rolled by electric automobile, so such cable also should
This meets special mechanical property requirements, as circumnutated, bend and vehicle field compaction test etc..
The structure of existing electric car conduction charging system cable is as it is shown in figure 1, include by many insulated wire cores 10
Stranded cable core, holding wire 11, cable core and holding wire are together coated on interior nonwoven layer 12 and are coated on non-woven fabrics
Restrictive coating 13 outside layer 12.Gap between nonwoven layer 12 and insulated wire cores 10 is filled with packing material 14.
Insulated wire cores 10 includes the stranded conductor of multi beam strand 101 and the insulating barrier 102 being coated on outside conductor 101.
Strand uses the structure of layer-stranding to form conductor 101, and innermost layer is single strand, and remainder layer is the most stranded by multi beam strand
Form, outside by innermost layer, in last layer is all closely enclosed in by each layer.Except innermost layer, twist between adjacent layer on the contrary.
But the cable of this structure has the following disadvantages: 1, 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 layer 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 relatively big, and the bending radius causing conductor and cable core is little, conductor and
The pliability of cable core can not meet cable and frequently move, bends and the requirement of resistance to torsion.2, nonwoven layer uses eclipsed form wrapped
In cable core and holding wire being together coated on, this structure cable core can not contact with restrictive coating, cable when being frequently bended and reverse,
Cable core each occurs position to move with restrictive coating, causes cable to play bag, conductor break, and restrictive coating damages, shortens making of cable
Use the life-span.3, the cross section of insulated wire cores is generally circular in cross section, then the gap between insulated wire cores is relatively big, existing packing material
For polyethylene rope, it is impossible to ensure the roundness of cable.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, and a kind of electric car conduction charging system electricity consumption is provided
Cable.It has higher flexibility, outstanding anti-outer pressure, good oil resistivity, splendid low-temperature flexibility and the anti-electromagnetism of carrying is done
Immunity.Solve that existing electric car conduction charging system Cable Bending Radius is little, pliability inadequate, cable during use
Core is the most each subjected to displacement with restrictive coating, causes cable to play bag, conductor break, and restrictive coating damages, and roundness does not reaches and wants
The problem asked.
The technical scheme is that a kind of electric car conduction charging system cable, including cable core and holding wire, cable
Core is formed by many insulated wire cores are stranded, also includes cable core and holding wire are together coated on interior mylar belt；Successively
It is coated on the inner restrictive coating outside mylar belt, electro-magnetic screen layer, nonwoven layer and external sheath layer；And it is filled in inner sheath
Implant in gap between layer and insulated wire cores；Nonwoven layer uses clearance-type wrapped, and clearance rate is 20%～30%；Polyester
Film strips layer uses eclipsed form wrapped, and Duplication is not less than 25%.
The further technical scheme of the present invention is: implant includes aramid yarn.
The present invention further technical scheme is: implant also includes packing.
The further technical scheme of the present invention is: insulated wire cores includes that the stranded conductor of multi beam strand and being coated on is led
External insulating barrier；Strand uses the structure of layer-stranding to form conductor, and innermost layer is single strand, and remainder layer is by multi beam stock
Line is the most stranded to be formed, outside by innermost layer, in last layer is all closely enclosed in by each layer, and each layer of remaining in addition to innermost layer
Strand is to identical, and the stranded lay ratio of remaining each layer in addition to innermost layer is 8～10 times.
The further technical scheme of the present invention is: electro-magnetic screen layer includes plastic-aluminum belt and wrapped braiding copper wire thereon
Layer.
The present invention further technical scheme is: it is 12～14 times that insulated wire cores is twisted into the lay ratio of cable core
The present invention compared with prior art has the advantage that
1, implant adds packing and be twisted into a closely knit entirety, greatly improve the resist bending of cable, anti-torsion
Can, make cable entirety have outstanding anti-outer load pressure and thermal stress, good oil resistivity and splendid low-temperature flexibility.
2, implant includes packing and aramid yarn, the diameter of packing and the equal diameters of insulated wire cores, and uses close
Degree and hardness, more than the TPE material of aramid yarn, can increase the stability of the construction of cable, it is ensured that the rounding property of cable.
3, compared to existing cable, adding electro-magnetic screen layer, it 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 produces is disappeared by aluminum plastic belt major part
Removing, surface transfer impedance is less than 10 (CQC standard is less than 250), cancels out each other in the magnetic field that both produce.
4, in using mylar tape cable core and holding wire to be together coated on, and use eclipsed form wrapped, it is simple to cable
Core is tightened, it is ensured that the rounding property of cable, is also convenient for cable core in rear operation and combines closely with inner restrictive coating, facilitates charging pile cable
The joint of terminal.
5, the conductor of insulated wire cores is to be formed by strand layer-stranding, and each layer of remaining in addition to innermost layer twists to identical, soft
Soft getting a promotion, bending radius reaches 5D (D is finished cable diameter), and the stranded lay ratio of each layer of remaining in addition to innermost layer is
8～10 times, it is 12～14 times that insulated wire cores is twisted into the lay ratio of cable core, and compared with existing cable, lay ratio reduces, bending
Radius reduces further.
Below in conjunction with figure, the invention will be further described with embodiment.
