Description
Technical field
The utility model relates to wires and cables industry, is specifically related to a kind of charging device of electric automobile stube cable.
Background technology
Since in September, 2008; in the face of financial crisis; price of oil going up sky-high and increasingly serious energy-saving and emission-reduction pressure; greatly developing new-energy automobile becomes a new focus of World Auto Industry competition; in this process; electric automobile becomes the representative of new-energy automobile gradually; under the promotion of enterprise; it also becomes the strategic industry direction that each government of Main Auto manufacturing power of the world determines gradually; leading in order will in new round global competition, to continue; Germany; Japan; the U.S.; the states such as Britain; change all of a sudden; directly appeared by the central government in 2010; the policies and measures of a series of comprehensive promotion new-energy automobile industry development have been put into effect; cause world's common concern; China also in time classifies new-energy automobile as the national strategy new industry; some policies and measures have been put into effect; electric automobile is the direction that following automobile market develops; the development of electric automobile will inevitably bring the construction of electric automobile charging station; it is the trend of the times of social development; therefore the Development of EV charging arranges equipment cable good society and economic benefit; this electric automobile charging pile need satisfy following special performance requirement with cable: cable is flexible cable; but require anti-vehicle-mounted pressure; the structure of the structure of the conductor of cable and core stranding needs to optimize; require insulation; sheath material has very high intensity and pliability; cable is the mobile cable that uses; need to stand long-term pulling and alternating bending; and the possibility Long Term Contact is to greasy dirt; cable should be very soft; Stability Analysis of Structures; and wear-resisting; oil resistant; the charging device of electric automobile stube cable does not form unified standard at present; what large department used all is that conventional general rubber sleeve flexible cable replaces using, and this cable uses as the charging device stube cable has the anti-ability that rolls; wear-resisting solvent resistance is poor; flexibility is not enough; the shortcoming that useful life is short.
The utility model content
The purpose of utility model: for addressing the above problem, the utility model provides a kind of long service life, charging device of electric automobile stube cable that resistance to wear is good.
Technical scheme: for achieving the above object, the utility model adopts following technical scheme:
A kind of charging device of electric automobile stube cable, described sheath, two master cores and the signal controlling core of comprising, described master core and signal controlling core are located in the cable cover(ing), all are enclosed with the master core insulation outside every master core conductor, and the core number of described signal controlling core is at least one.
As optimization, be provided with woven shield in the described cable cover(ing).
Further, the gap in the described cable woven shield is filled with inner sheath.
As optimization, the gap in the described sheath is filled with inner sheath.
Conductor described in the utility model is zinc-plated soft copper conductor, insulation is 60 ℃ of ethylene-propylene rubber/90 ℃ ethylene-propylene rubber/thermoplastic elastomer (TPE)/cross-linked polyolefins, screen is the tinned copper wire braid shielded, and sheath is neoprene or equivalent material/polyurethane/thermoplastic elastomer (TPE)/cross-linked polyolefin.
Cable is flexible cable, but require anti-vehicle-mounted pressure, the structure of the structure of the conductor of cable and core stranding needs to optimize, and requires insulation, sheath material to have very high intensity and pliability, and cable is the mobile cable that uses, need to stand long-term pulling and alternating bending, and may Long Term Contact to greasy dirt, cable should be very soft, Stability Analysis of Structures, and wear-resisting, oil resistant.
Be strict with the design of the construction of cable, select the suitable insulating sheath material that meets the demands, guarantee that cable product is by every test:
Electric performance test: conductor DC resistance, withstand voltage test, insulation resistance, jacket surface resistance;
Physical and chemical performance test: tensile strength and elongation at break before insulation and sheath are aging, tensile strength and elongation at break after insulation and sheath are aging, air bomb test (being only applicable to ethylene propylene rubber insulated), hot elongation test (is only applicable to the cross-linking type insulation, sheath material), the sheath pH resistance test, sheath water resistant test (being only applicable to polyurethane jacket and thermoplastic elastomer sheath), sheath cracking resistance test (being only applicable to polyurethane jacket and thermoplastic elastomer sheath), sheath Apparatus for Pressure at high-temp (being only applicable to polyurethane jacket and thermoplastic elastomer sheath), insulation and sheath low temperature bend test (being applicable to the sample of cable mean outside diameter≤12.5mm), sheath cryogenic tensile test (being applicable to the sample of cable mean outside diameter＞12.5mm), low-temperature impact test, the sheath tear resistance test, ozone resistance test (only is suitable for ethylene propylene rubber insulated, cross-linked polyolefin insulation or sheath), sheath water absorption test (cross-linked polyolefin sheath), compatibility test, the liquid receptive test, the test that circumnutates (is only applicable to cross section≤2.5mm
2Cable), static flexibility test, atmospheric exposure test, vehicle-mounted pressure test;
Fire protecting performance test: testing vertical flammability.
Beneficial effect: cable described in the utility model adopts 6 class soft structure conductor and flexible materials, has overcome the shortcoming of universal product flexibility deficiency; Cable cover(ing) has adopted high-abrasive material, has overcome the characteristics that the universal product wears no resistance; Cable sheath material intensity is large, and product adopts the embedded filling of sheath, and close structure, stable has overcome the poor characteristics of universal product rolling resistance; Cable cover(ing) has adopted the excellent material of chemical solvent resistance energy, the poor characteristics of universal product chemically-resistant solvent have been overcome, the product various performance parameters is all simulated actual operating position design, being suitable for the charging device field uses, the utility model long service life, resistance to wear are good, are fit to being widely used of relevant industries.
