Utility model content

The purpose of this utility model is to provide a kind of environmentally friendly 150 DEG C of vehicle-mounted cables of high temperature resistant New-energy electric vehicle, with The problem of solving to propose in above-mentioned background technology.

To achieve the above object, the utility model provides following technical scheme：A kind of 150 DEG C of high temperature resistant new energy electricity of environmental protection The vehicle-mounted cable of electrical automobile, including conductor, insulating barrier, braiding layer, lapping layer and sheath, the conductor are twisted in the same direction entirely by copper monofilament Close and be made, the insulating barrier is coated with outside the conductor, the insulating barrier is coated with outside the braiding layer, the braiding layer It is coated with outside lapping layer, the lapping layer and is arranged with the sheath, the insulating barrier and the sheath is adopted as cross-linked thermoplastic Elastomer is made.

It is preferred that, the copper monofilament filament diameter that the conductor is used for 0.14mm, the requirement of copper monofilament elongation percentage it is consistent and More than 25%, twisting pitch is 2 times of strand pitch when copper monofilament is stranded.

It is preferred that, the crosslinked thermoplastic elastomer that the insulating barrier and the sheath are used is 150 DEG C of cross-linking radiation thermoplastic Property elastomer.

It is preferred that, the braided wires of the braiding layer use 0.12mm tinned copper wires.

It is preferred that, the twining package tape of the lapping layer use thickness for 0.025 aluminium-plastic tape.

Compared with prior art, the beneficial effects of the utility model are：150 DEG C of high temperature resistant New-energy electric vehicles of the environmental protection Vehicle-mounted cable in use, the present apparatus use insulating barrier and sheath use by be crosslinked TPE by radiation treatment obtain have it is resistance to It is made by 150 DEG C of cross-linking radiation thermoplastic elastomer (TPE)s of 150 DEG C of temperature performances, and the temperature grade of the sheath of normal cable at present For 125 DEG C, so the present apparatus obtains larger lifting in high temperature tolerance ability, while 150 DEG C of cross-linking radiation thermoplastic elastomehcs The all properties such as bending property, the oil resistant of property body meet the use demand of the road vehicle high-tension cables of QC/T 1037, and And pliability is much better than the pliability of the crosslinking TPE materials of normal cable sheath use, the copper filament diameter filament diameter of conductor For 0.14mm, less than the copper filament diameter of current traditional cable, such design causes the conductor of the present apparatus is obtained smaller Bending radius, carry out copper monofilament it is stranded when it is stranded using complete stranded mode in the same direction, strand and twisted layer using it is a kind of more reasonably Pitch is configured, and twisting pitch is 2 times of strand pitch, reaches the effect of a bundle strand；Mechanicalness of the present apparatus than traditional cable Can more preferably, while security is improved, insulating properties is very good, while being resistant to higher temperature, reducing cable makes Used time triggers the probability of failure because operating ambient temperature is too high.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belongs to the scope of the utility model protection.

Referring to Fig. 1, the utility model provides a kind of technical scheme：A kind of 150 DEG C of high temperature resistant New energy electric vapour of environmental protection The vehicle-mounted cable of car, including conductor 1, insulating barrier 2, braiding layer 3, lapping layer 4 and sheath 5, the conductor 1 are entirely in the same direction by copper monofilament It is stranded to be made, the insulating barrier 2 is coated with outside the conductor 1, the insulating barrier 2 is coated with the braiding layer 3, described to compile Tissue layer 3 is coated with outside lapping layer 4, the lapping layer 4 and is arranged with the sheath 5, and the insulating barrier 2 and the sheath 5 are adopted It is made for crosslinked thermoplastic elastomer, the copper monofilament filament diameter that the conductor 1 is used is 0.14mm, and copper monofilament elongation percentage will Ask consistent and more than 25%, twisting pitch is 2 times of strand pitch when copper monofilament is stranded, the insulating barrier 2 and the sheath 5 The crosslinked thermoplastic elastomer used is 150 DEG C of cross-linking radiation thermoplastic elastomer (TPE), and the braided wires of the braiding layer 3 are used 0.12mm tinned copper wires, the twining package tape of the lapping layer 4 use thickness for 0.025 aluminium-plastic tape.
