Description
Technical field
The utility model belongs to technical field of cables, especially relates to the inner pair sheath high pressure stube cables of using of electric automobile with ultra-soft aluminum conductor.
Background technology
Automotive interior is a kind of for electric connection line with high pressure stube cable, the primary high-voltage transmission for vehicle interior.Communication power supply not only requires to have good flexibility with flexible cable, to conveniently lay under situation, and requires to have desirable anti-flammability in narrow space or similarly, to adapt to higher fire-protection rating requirement.
The cable for car overwhelming majority adopts copper conductor both at home and abroad at present, and copper conductor itself is heavier, and flexibility is poor; Conventionally adopt communication power supply to substitute use with flexible cable both at home and abroad.
Can in disclosed Chinese patent literature, be seen in by the technical information of flexible cable about communication power supply, for example CN201247632Y recommends have that " communication power supply is with fire-retardant, fire-resistant, shielding anti-interference flexible cable ", CN201302849Y provides " a kind of communication power supply flame-retardant refractory flexible electric cable ", CN202230791Y discloses " the flame-retardant crosslinking polyethylene insulated flexible cable of a kind of communication power supply ", CN202720953U introduces to be had " for watt form drag combustion shielded flexible cable of communication power supply ", CN202855416U discloses " communication power supply fire-resistant shield flexible cable " and CN202601277U disclosed " a kind of communication power supply flame-retardant flexible electric cable ", etc..
Although communication power supply of the prior art respectively has corresponding technique effect with flexible cable, there is following common defect: (1) due to using stranded thin copper wire as conductor, its soft degree can not meet the desired requirement.And because pliability is poor, bending radius is restricted, thus at narrow space, hindered by immovable object and even when the occasion at the place of talking in a roundabout way and so on is laid, very easily affect speed of application, particularly in the less occasion in the spaces such as vehicle; (2) owing to generally selecting the conductor as flexible cable with copper under technology prejudice, thereby not only there is the blindness that rationally uses raw material aspect, and cause the manufacturing cost of flexible cable large; Its three, because copper density is large, therefore cable weight is heavier, thereby not only logistics transportation, the cost of storage in link are high, and workmen's labour intensity is large in laid processes, to consume cost of labor high.
In view of above-mentioned prior art, still have improved necessity, the applicant has done useful design for this reason, has formed technical scheme described below.
