Abstract

The invention discloses a cable for charging an electric automobile. The cable comprises a plurality of insulating wire cores outside which a woven shielding layer is lapped, wherein a polyurethane elastomer sheath layer is extruded outside the woven shielding layer; each insulating wire core comprises a stranded conductor, a copper strip reinforcing lapped layer and a low-smoke zero-halogen irradiation crosslinked polyolefin insulating layer; the copper strip reinforcing lapped layer is extruded outside the stranded conductor; the low-smoke zero-halogen irradiation crosslinked polyolefin insulating layer is extruded outside the copper strip reinforcing lapped layer; and the space between the insulating wire cores and the woven shielding layer is filled with a polyvinyl chloride isolating layer. The invention has the advantages that: the cable has a simple structure, is convenient to use, has high weather resistance and long life, is environmentally-friendly, can be used outdoors for a long time and works stably and reliably.

Description

A kind of charging electric vehicle is used cable

Technical field

The present invention relates to a kind of cable, relate in particular to a kind of charging electric vehicle and use cable.

Background technology

The common cable that uses on the electric automobile at present, relatively simple for structure, generally adopt the insulating barrier and the sheath of pvc material; But because electric automobile moves for a long time out of doors, the vehicle-mounted pressure and the frictional force of cable are bigger, add often be exposed to outside; Cause cable conductor structural impaired; The bending property of electrical property, cable all reduces, and the part also causes impaired easily, and the damaged part conductor move the inefficacy of sliding property finally cause cable at last herein conductor fracture; Thereby caused problems such as reduction of cable security reliability and shortening in useful life, also influenced the stability and the fail safe of electric automobile whole.

Summary of the invention

Be technical deficiency more than solving, the invention provides and a kind ofly have simple in structurely, easy to use, can effectively improve the charging electric motor vehicles in cable security reliability and cable useful life and use cable.

The present invention realizes through following measure:

A kind of charging electric vehicle of the present invention is used cable; Comprise insulated wire cores; Some insulated cores are surrounded with woven shield outward; Said woven shield outer surface is extruded with the polyurethane elastomer sheathing layer; Said insulated wire cores comprises stranded conductor, is extruded in the copper strips reinforcement lapping layer of stranded conductor outer surface and is extruded in the low smoke and zero halogen cross-linking radiation polyolefin insulation layer that copper strips is strengthened the lapping layer outer surface, is filled with the polyvinyl chloride separator between said insulated wire cores outer surface and the woven shield inner surface [0005]Preferably, above-mentioned stranded conductor is naked copper or zinc-plated stranded conductor.

Preferably, it is narrow copper strips that above-mentioned copper strips is strengthened lapping layer, and double-deck wrapped outside stranded conductor.

Preferably, above-mentioned woven shield is a tinned copper wire.

The invention has the beneficial effects as follows: wrapped copper strips is strengthened lapping layer outside stranded conductor can also have raising to the conductor electrical property to perpendicular to the reinforcement of cable direction conductor mechanical strength, anti-vehicle-mounted pressure.The outer squash type of the stranding cable core of stranded rounding extrudes separator and can rounding property, the mechanical strength of cable be greatly enhanced, and woven shield has the booster action that plays how whole cable machinery intensity simultaneously.Solved perpendicular to cable direction conductor bad mechanical strength, the problem of anti-vehicle-mounted pressure not, simple in structure, easy to use, good weatherability, life-span length, environmental protection, long-term outdoor use, working stability are reliable.

Description of drawings

Fig. 1 is a structural representation of the present invention.

Among the figure: 1. polyurethane elastomer sheathing, 2. woven shield, 3. polyvinyl chloride separator, 4. low smoke and zero halogen cross-linking radiation polyolefin insulation layer, 5. copper strips is strengthened lapping layer, 6. stranded conductor.

Embodiment

As shown in Figure 1; A kind of charging electric vehicle of the present invention is used cable; Comprise insulated wire cores, some insulated cores are surrounded with woven shield 2 outward, the woven shield 2 outer polyurethane elastomer sheathings 1 that are extruded with; Insulated wire cores comprises stranded conductor 6, is extruded in the copper strips reinforcement lapping layer 5 outside the stranded conductor 6 and is extruded in copper strips and strengthen the low smoke and zero halogen cross-linking radiation polyolefin insulation layer 4 outside the lapping layer 5, is filled with polyvinyl chloride separator 3 between insulated wire cores and the woven shield 2.

Stranded conductor 6 is naked copper or zinc-plated stranded conductor 6, can design according to the pliability needs, adjusts stranded filament diameter and radical.

It is narrow copper strips that copper strips is strengthened lapping layer 5, double-deck wrapped outside stranded conductor 6.Can be according to conductor specification adjustment copper strips thickness and width.

Low smoke and zero halogen cross-linking radiation polyolefin insulation layer 4 possesses excellent electric performance, high-low temperature resistant, useful life, mechanical-physical property.

Polyvinyl chloride separator 3 adopts polyvinylchloride, possesses excellent weatherability, mechanical performance.

Woven shield 2 is a tinned copper wire, is woven in outside the separator.According to separator external diameter adjustment braiding filament diameter and braiding parameter, guarantee count.

Polyurethane elastomer sheathing 1 is the polyurethane elastomer material, and squash type is extruded in outside the woven shield 2.Possess excellent weatherability, wear-resisting, oil resistant, anticorrosion, antimicrobial, mechanical performance.

Low smoke and zero halogen cross-linking radiation polyolefin insulation layer 4 is carried out cross-linking radiation, polyvinyl chloride separator 3, woven shield 2 and polyurethane elastomer sheathing more than 1 each layer combination make whole electric automobile with charging cable possess that anti-vehicle-mounted pressure, high-low temperature resistant, life-span are long, wear-resisting, oil resistant, anticorrosion, antimicrobial, high tensile property, stable high characteristic.Its wrapped copper strips outside stranded conductor 6 can also have raising to the conductor electrical property to perpendicular to the reinforcement of cable direction conductor mechanical strength, anti-vehicle-mounted pressure.The outer squash type of the stranding cable core of stranded rounding extrudes separator and can rounding property, the mechanical strength of cable be greatly enhanced, and woven shield 2 has the booster action that plays how whole cable machinery intensity simultaneously.

The foregoing description is said to be in order to specify this patent; Though describe through specific term in the literary composition; But can not limit the protection range of this patent with this; The personage who is familiar with this technical field can change or revise it after the spirit of understanding this patent and principle and reach equivalent purpose, and this equivalence change and modification all should be covered by the claim scope and define in the category.
