Description
Technical field
The invention belongs to electric automobile and technical field of cables, especially relate to a kind of electric automobile internal high pressure and connect use
Cable, especially relates to use the cable of aluminium alloy conductor.
Background technology
It is a kind of for electric connection line, the primary high-voltage transmission for vehicle interior that automotive interior high pressure connects cable.Logical
Letter power supply flexible cable does not require nothing more than has good flexibility, in order to convenient deposited in narrow space or when similar
If, and require there is preferable anti-flammability, to adapt to higher fire-protection rating requirement.
The Application No. of our company: 2014104424205 and entitled: " a kind of electronic vapour with super soft aluminium conductor
Connect cable and preparation method thereof with high pressure inside car ", Application No.: 2014104424313 and entitled: " there is super softness
Connect cable and preparation method with high pressure inside the electric automobile of aluminium conductor ", Application No.: 2014104424328 and title
For: in " the internal double sheath high pressure of electric automobile with ultra-soft aluminum conductor connect cable and preparation method " patent, use aluminium
Conductor substitutes copper conductor, has reached to save the purpose of Zhi Jiangben；But, owing to the hardness of aluminium is the highest, although softness can be reached
Purpose, but its tensile property is poor, is easier to creep, corrosion resistance and thermal expansion aspect not ideal enough.

CN201247632Y recommends have " fire-retardant, fire-resistant, the shielding anti-interference flexible cable of communication power supply ", CN201302849Y to be provided with
" a kind of communication power supply flame-retardant refractory flexible electric cable ", CN202230791Y are disclosed " a kind of poly-second of communication power supply flame-proof cross-linking
Alkene insulated cable ", CN202720953U introduce have " for the shoe flame-retardant shielding flexible cable of communication power supply ",
CN202855416U discloses " communication power supply fire-resistant shield flexible cable " and disclosed " a kind of communication power supply of CN202601277U
With flame-retardant flexible electric cable ", etc..
Although communication power supply flexible cable of the prior art is respectively arranged with corresponding technique effect, but exists following common
Defect: (1) is owing to using stranded thin copper wire as conductor, its softness can not meet desired requirement.And due to
Pliability difference and make bending radius be restricted, thus narrow space, by immovable object hinder so that talk in a roundabout way
When the occasion at place etc is laid, easily affect speed of application, particularly in the occasion that the spaces such as vehicle are less；(2) due in skill
Generally select the conductor using copper as flexible cable under art prejudice, thus do not only exist the blindness in terms of reasonable employment raw material, and
And cause the manufacturing cost of flexible cable big；Its three, owing to copper density is big, therefore cable weight is heavier, thus not only logistics transportation, storehouse
