Abstract
Provided is an electric automobile DC charging flat cable which comprises two two-phase power supply lines, and two power supply auxiliary lines, three communication lines and one shielding line. The auxiliary lines, the communication lines and the shielding line are twisted together as a whole which is wrapped with a first inner protective layer in a pressing way. The first inner protective layer is wrapped with a first metal shielding layer and thus a control line core is formed. The control line core is arranged in parallel with the two power supply lines and the three are wrapped with a third inner protective layer in the pressing way. The third inner protective layer is wrapped with a fourth metal shielding layer which is wrapped with an outer protective sheath. One of the power supply lines comprises two conductors which are arranged in parallel and wrapped with a second inner protective layer in the pressing way. The second inner protective layer is wrapped with a second metal shielding layer. The other power supply line comprises a conductor which is wrapped with a third metal shielding layer. The communication lines, the shielding line and the auxiliary lines are all composed of the conductors and a fifth metal shielding layer. Charging efficiency and the service life of the cable are greatly enhanced and thus heating and breakage of the cable can be effectively prevented.
Description
Technical field
The utility model relates to a kind of charging electric motor vehicles cable, and direct current charging cable especially is set.
Background technology
continuous progress and economic fast development along with social production, country has strengthened the process of helping and developing to New-energy electric vehicle at present, now country and relevant electric network consecutive have been formulated construction that related standards obtains electric power to electric automobile the requirement of standard. and we know that the power of electric automobile is electric power, and electric automobile to obtain at present the method for electric power be mainly by the storage battery electric power storage, in case just need recharge again after storage battery is finished, and be power supply can be input to automobile by the electric wire connection side between charging pile and automobile, and implement signal controlling and complete whole charging process, although the cable of existing technology has possessed the control of charging of control cable, but its anti-performance that rolls, and the shielding properties of metal screen layer still can't meet than rugged environment, especially the ground connection performance of its metal-shielded wire is difficult to effective assurance, easily in long-term use Fracture and short circuit, have much room for improvement.
Summary of the invention
The utility model, for the deficiencies in the prior art, provides a kind of good toughness, and crushing resistance can be good, the electric automobile DC charging flat cable of long service life.
key problem in technology of the present utility model is to change the set-up mode of a power line inner wire, make it be set to two bursts of modes arranged side by side, increase the performance of charging, moreover set up glass fibre in inner sheath, greatly improve ductility and tensile property, its technology technical scheme is: a kind of electric automobile DC charging flat cable, it is characterized in that comprising two two-phase power supply lines and two power supply boost lines, three with order wire, a shielding conductor, described boost line, order wire and shielding conductor twist together and are extruded with the first sheath, the first sheath is coated with the first metal screen layer, form and control core, described control core and two power lines are set up in parallel and extrude the 3rd sheath, the 3rd sheath outer cladding the 4th metal screen layer, the 4th metal screen layer is coated with oversheath, a described power line comprises two strands of conductors arranged side by side, and conductor extrudes the second sheath outward, and second sheath outer cladding the second metal screen layer, another root power line comprise one conductor and at conductor outer cladding the 3rd metal screen layer, described order wire, shielding conductor and boost line belong to the screen formation by conductor and five metals.Be provided with some bundle glass fibres in described the 3rd sheath.
, as preferably, have additional equadag coating between the 4th metal screen layer and oversheath.By this kind setting, the better and heat-proof quality of shield effectiveness is increased.
As preferably; the 4th metal screen layer is to form along the cross-section of cable spaced some protective earthing lines successively; described protective earthing line is bare copper wire; described bare copper wire is arranged loose in the arc transition section of the cross-section of cable; at the straightway dense arrangement of the cross-section of cable, and arc transition section place copper wire diameter is greater than straightway place copper wire diameter.Improve ductility and the shield effectiveness of cable when by this kind setting, improving again the ground connection performance.
As preferably, described conductor is the non-stranded core of straight line.
The beneficial effects of the utility model: the utility model has improved the useful life of charge efficiency and cable greatly, effectively prevents electric cable heating and fracture.
