Description

A kind of charging device of electric automobile stube cable

Technical field

The present invention relates to wires and cables industry, be specifically related to a kind of charging device of electric automobile stube cable.

Background technology

Since in September, 2008,, greatly developed the new focus that new-energy automobile becomes the world car competition in the industry in the face of financial crisis, the surging and increasingly serious energy-saving and emission-reduction pressure of oil price; In this process, electric automobile becomes the representative of new-energy automobile gradually, under the promotion of enterprise; It also becomes each definite strategic industry direction of main automobile making government of power of the world gradually, and is leading in order will in new round global competition, to continue, states such as Germany, Japan, the U.S., Britain; Change all of a sudden, directly appeared by the central government, put into effect the policies and measures of a series of comprehensive promotion new-energy automobile industry development in 2010; Cause world's common concern, China also in time classifies new-energy automobile as national strategy property new industry, has put into effect some policies and measures; Electric automobile is the direction that following automobile market develops, and the development of electric automobile will inevitably bring the construction of electric automobile charging station, is the trend of the times of social development; Therefore develop charging electric vehicle and the equipment cable is set good society and economic benefit are arranged, this electric automobile charging pile need satisfy following special performances with cable and require: cable is a flexible cable, but requires 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 uses cable for moving; Need to stand long-term pulling and alternating bending, and possibly touch greasy dirt for a long time, 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 big department used all is that conventional general rubber sleeve flexible cable replaces using, and this cable uses as the charging device stube cable has anti-ability, wear-resisting solvent resistance is poor, flexibility not enough, useful life the is short shortcoming of rolling.

Summary of the invention

The purpose of invention:, the invention provides a kind of long service life, charging device of electric automobile stube cable that resistance to wear is good for addressing the above problem.

Technical scheme: for achieving the above object, the present invention adopts following technical scheme:

A kind of charging device of electric automobile stube cable; Said sheath, two master cores and the signal controlling core of comprising; Said master core and signal controlling core are located in the cable cover(ing), outside every master core conductor, all are enclosed with the master core insulation, and the core number of said signal controlling core is at least one.

As optimization, be provided with woven shield in the said cable cover(ing).

Further, the gap in the said cable woven shield is filled with inner sheath.

As optimization, the gap in the said sheath is filled with inner sheath.

Conductor of the present invention 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 a flexible cable, but requires anti-vehicle-mounted pressure, and the structure of the structure of the conductor of cable and core stranding needs to optimize; Require insulation, sheath material to have very high intensity and pliability, cable uses cable for moving, and needs to stand long-term pulling and alternating bending; And possibly touch greasy dirt for a long time, cable should be very soft, Stability Analysis of Structures; And wear-resisting, oil resistant.

Be strict with the design of the construction of cable, the suitable insulation sheath material that selection meets the demands guarantees that cable product passes through each item 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; Insulation and sheath aging back tensile strength and elongation at break; 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 test of liquid receptive property; 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 of the present invention adopts 6 types of soft junction structure conductors and flexible material, has overcome the not enough shortcoming of universal product flexibility; Cable cover(ing) has adopted high-abrasive material, has overcome the characteristics that the universal product wears no resistance; Cable sheath material intensity is big, and product adopts the embedded filling of sheath, and structure is tight, stable, has overcome the characteristics of universal product rolling resistance property difference; Cable cover(ing) has adopted the excellent material of chemical solvent resistance ability; The characteristics of universal product chemically-resistant solvent difference have been overcome; The product various performance parameters is all simulated actual operating position design; Be suitable for the charging device field and use, long service life of the present invention, resistance to wear are good, are fit to being widely used of relevant industries.
