Abstract
The utility model discloses a cable for electric vehicles, which comprises a core layer. The core layer is formed by winding flexible copper wires once and stranding multiple times, an insulation layer is circularly wrapped on the outer surface of the core layer, a shield layer is wrapped on the outer surface of the insulation layer circularly, and a thermoplastic elastic sheath layer is wrapped on the outer surface of the shield layer circularly. The cable for electric vehicles is fine in flexibility and bendability, simple in structure and durable.
Description
Technical field
The utility model relates to a kind of cable, and more particularly, it relates to a kind of cable that is used for using on the electric automobile.
Background technology
At present, the defective below the used for electric vehicle cable ubiquity of selling on the market: the pliability of cable conductor structural is not high, and cable flexibility and the bending property produced like this are bad; The weaving method of screen is science not, causes the exposed insulating barrier that punctures in conductor termination, braiding back easily, and the crooked energising of cable back punctures insulating barrier easily; Insulating barrier and restrictive coating adopt the cross-linked polyolefin material, and Boardy Feeling is used easy of crack for a long time.
The utility model content
The novel deficiency for avoiding above-mentioned prior art to exist of this use provides a kind of flexibility, good bandability, simple in structure, long-lived electric automobile cable.
The technical scheme that the utility model solves its technical problem is:
A kind of electric automobile cable comprises inner sandwich layer, described inner sandwich layer be the flexibility copper wire once restraint around, repeatedly multiple strand forms; The inner sandwich layer outer surface is around being coated with insulating barrier, and the insulating barrier outer surface is around being coated with screen, and the screen outer surface is around being coated with the thermoplastic elastomer sheath layer.
The utility model passes through to adopt said structure, thereby the utlity model has following beneficial effect:
Soft copper wire is once restrainted strand, repeatedly multiple strand forms, and makes cable soft because the heart yearn of inner sandwich layer adopts, and bending radius is little, and passes through the combination of inner sandwich layer, insulating barrier, screen, restrictive coating, thereby the utlity model has: 1, flexibility is good; 2, good bandability; 3, simple in structure, durable in use.
Description of drawings
Fig. 1 is the organigram of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe.
In Fig. 1, a kind of electric automobile cable comprises inner sandwich layer 1, inner sandwich layer 1 for the flexibility copper wire once restraint around, repeatedly multiple strand forms; Inner sandwich layer 1 outer surface is around being coated with insulating barrier 2, and insulating barrier 2 outer surfaces are around being coated with screen 3, and screen 3 outer surfaces are around being coated with thermoplastic elastomer sheath layer 4.Above-mentioned inner sandwich layer 1, insulating barrier 2, screen 3, thermoplastic elastomer sheath layer 4 can be overmolding to an integral body through hot melt.
The heart yearn of inner sandwich layer 1 adopts that soft copper wire is once restrainted strand, repeatedly multiple strand forms, and makes cable soft, and bending radius is little; The braided metal wire terminal of the use in the screen 3 adopts the mode of welding to connect, and insulating barrier 2 adopts thermoplastic elastomer (TPE) with thermoplastic elastomer sheath layer 4, is applicable under-40 ℃～125 ℃ conditions and uses.
Though described the execution mode of the utility model in conjunction with accompanying drawing; But those skilled in the art can make various distortion or modification within the scope of the appended claims; As long as be no more than the described protection range of the claim of the utility model, all should be within the protection range of the utility model.
Claims (1)
1. an electric automobile cable comprises inner sandwich layer, it is characterized in that: described inner sandwich layer be the flexibility copper wire once restraint around, repeatedly multiple strand forms; The inner sandwich layer outer surface is around being coated with insulating barrier, and the insulating barrier outer surface is around being coated with screen, and the screen outer surface is around being coated with the thermoplastic elastomer sheath layer.
