Description
Technical field
The present invention relates to electric wire field, specifically a kind of electric vehicle charging cable.
Background technology
New-energy electric vehicle is in charging field at present, and existing charging pile charge efficiency is low, and the charging time is long, in order to
More responsive to China " 13 planning " to New-energy electric vehicle demand for development.To improve charge efficiency, when shortening charging
Between, it is charged using low-voltage direct high current to new energy car battery, charging pile rifle cable is connect as with automobile energy storage
Tie plays extremely important effect.
The common cable used on electric vehicle at present, relatively simple for structure, the general insulation for using pvc material
Layer and sheath, but since electric vehicle moves outdoors for a long time, the vehicle-mounted pressure and frictional force of cable are bigger, along with frequent
Be exposed to outer, cable conductor structural caused to be damaged, electrical property, cable bending property reduce, be locally also easy to cause to be damaged,
And the shifting slip failure of damaged part conductor eventually leads to cable finally conductor fractures here, safely may be used so as to cause cable
The problems such as by property reduction and reduced service life, also affect stability and the safety of electric automobile whole.
Invention content
The purpose of the invention is to overcome the deficiencies of the prior art and provide a kind of to have that anti-aging, tensile strength is small, resistance to
The strong electric vehicle charging cable of acid-base property, rolling resistance, resistance to fracture.
A kind of electric vehicle charging cable of the present invention, including cable core, the cable core is by more master cores and one
Root signal core pair twist forms, in the gap filling glass silk gasket for packing of cable core, the wrapped layer glass silk band outside cable core,
Thermoplastic elastomer (TPE) oversheath is extruded outside glass fiber band；The master core is by six class twisted copper conductors and is extruded in six classes
Thermoplastic elastomer (TPE) insulating layer outside twisted copper conductors is formed；The signal core by six class twisted copper conductors, be extruded in six
Thermoplastic elastomer (TPE) insulating layer outside class twisted copper conductors, the shielding layer of copper wires being woven in outside thermoplastic elastomer (TPE) insulating layer and
The thermoplastic elastomer (TPE) inner sheath being extruded in outside shielding layer of copper wires is formed.
It is further improved, the thickness of the thermoplastic elastomer (TPE) oversheath is 4-5mm.
It is further improved, the thickness of the thermoplastic elastomer (TPE) inner sheath is 2-3mm.
Compared with prior art, the advantage of the invention is that：
1st, insulation is using thermoplastic elastic material, which has higher resistivity, and relatively thin thickness has very high resistance to
Electric strength, at the same heatproof be 125 DEG C, be halogen-free in material, processing performance is preferable, meet the product electrical property 600V and
Environmental performance demand；Sheath selects thermoplastic elastomer (TPE), which has preferable anti-flammability, has excellent wearability and resistance to
Oiliness can use at 125 DEG C for a long time, reachable -45 DEG C of low temperature, meet new-energy automobile and wanted in cold application in north China
It asks.
2nd, the outer squash type of stranding cable core for being twisted rounding extrudes layer glass silk band, not only acts as fire-retardant, fire resisting, also may be used
Rounding property, mechanical strength to cable are greatly enhanced, while to play more entire cable machineries strong for proof copper-wire braided shielded layer
The booster action of degree；It solves the problems, such as perpendicular to cable direction conductor bad mechanical strength, intolerant to vehicle-mounted pressure, it is simple in structure,
Easy to use, good weatherability, long lifespan, environmental protection, long-term outdoor use, are stable and reliable in work.
3rd, the present invention has resistance to vehicle-mounted pressure, high-low temperature resistant, long lifespan, wear-resisting, oil resistant, anti-corrosion, antimicrobial, high tensile
The characteristics such as property, stability height.
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
A kind of electric vehicle charging cable as shown in Figure 1, including cable core, the cable core is by more master cores and one
Signal core pair twist forms, in the gap filling glass silk gasket for packing 5 of cable core, the wrapped layer glass silk band 6 outside cable core,
Thermoplastic elastomer (TPE) oversheath 7 is extruded outside glass fiber band；The master core is by six class twisted copper conductors and is extruded in six
Thermoplastic elastomer (TPE) insulating layer 2 outside class twisted copper conductors 1 is formed；The signal core by six class twisted copper conductors, extrude
Thermoplastic elastomer (TPE) insulating layer outside six class twisted copper conductors, the shielding layer of copper wires being woven in outside thermoplastic elastomer (TPE) insulating layer
3 and the thermoplastic elastomer (TPE) inner sheath 4 that is extruded in outside shielding layer of copper wires form.
In order to make the rounding property of cable more preferable, the thickness of the thermoplastic elastomer (TPE) oversheath is 4-5mm；The heat
The thickness of thermoplastic elastic inner sheath is 2-3mm.
The outer squash type of stranding cable core of the twisted rounding of the present invention extrudes layer glass silk band, not only acts as fire-retardant, fire resisting,
Also it can be greatly enhanced, while proof copper-wire braided shielded layer plays how entire cable gear to the rounding property of cable, mechanical strength
The booster action of tool intensity；It solves the problems, such as perpendicular to cable direction conductor bad mechanical strength, intolerant to vehicle-mounted pressure, structure letter
Single, easy to use, good weatherability, long lifespan, environmental protection, long-term outdoor use, are stable and reliable in work.
The present invention has resistance to vehicle-mounted pressure, high-low temperature resistant, long lifespan, wear-resisting, oil resistant, anti-corrosion, antimicrobial, high tensile
The characteristics such as property, stability height.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the principle of the present invention, several improvement can also be made, these improvement also should be regarded as the present invention's
Protection domain.
