Abstract

An AC charging connection flat cable for an electromobile comprises three juxtaposed power lines, a neutral line and two control lines wherein an inner protecting layer is extruded among the power lines, the neutral line and the control lines, and a first metallic shielding layer, an insulating wrapping band and an oversheath are sequentially arranged outside the inner protecting layer. The first metallic shielding layer is formed by a plurality of protective grounding wires arranged at intervals along the cross section of the cable, wherein the protective grounding wires are bare copper wires, which are arranged loosely at the arc transition section of the cross section of the cable and densely at the linear section. The copper wires at the arc transition section are greater in diameter than the copper wires at the linear section. The AC charging connection flat cable has excellent anti-crushing and fracture performance and shielding effect, allows effective grounding and prolongs the service lifetime.

Description

A kind of electric vehicle alternating-current charging connection flat cable
Technical field
The utility model relates to a kind of alternating-current charging cable for electric automobile, relates in particular to a kind of flat cable of three-phase.
Background technology
Along with the continuous progress of social production and economic fast development, 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 the requirement that construction that related standards obtains electric power to electric automobile has had 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 after storage battery is finished, just need recharge again, and between charging pile and automobile, be power supply can be input to automobile by the electric wire connection side, and the enforcement signal controlling completes 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 is for the deficiencies in the prior art, provides a kind of and anti-ly rolls, fracture property is good, and shield effectiveness is good, the electric vehicle alternating-current charging connection flat cable of effective grounding, long service life.
Key problem in technology of the present utility model is the improvement to the first metal screen layer, by changing thickness and the density degree of bare copper wire in cross-section of cable different piece, effectively improve the reliability of ground connection, prevent unexpected generation, greatly improve the useful life of cable, its concrete technical scheme is: a kind of electric vehicle alternating-current charging connection flat cable, comprise three power lines that are set up in parallel, a neutral line and two control lines, described power line, between the neutral line and control line, be extruded with sheath, the described sheath outside is provided with the first metal screen layer successively, type insulating wrapping strip, oversheath, described two control lines are mutually stranded and be extruded with sheath, sheath is outward the second metal screen layer, described power line, the neutral line is comprised of conductor and insulating barrier from inside to outside successively, it is characterized in that described the first metal screen layer is for forming 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, straightway dense arrangement at the cross-section of cable, and arc transition section place copper wire diameter is greater than straightway place copper wire diameter.
As further improvement of the utility model, the described sheath extruded is at the slotting glass fibre of getting one's things ready that is embedded with.By this kind setting, greatly improve the anti-performance that rolls of sheath, effectively prevented cable breakage, improved its toughness, and effectively prevented distortion of the cable.
As further improvement of the utility model, described the first metal screen layer skin is coated with graphite linings.By this kind setting, greatly improved the shield effectiveness of metal screen layer.
Effective effect of the present utility model: the utility model, owing to adopting non-stranded core, is different from common stranded core, can not have twisted phenomena; Protective earthing bundle of lines internal core and outside keep apart fully, can guarantee the safety of personnel and equipment; Increased simultaneously the tensile property of product; adopt flat structure to be conducive to the anti-requirement that rolls; so meeting especially electric automobile charging station uses as mobile occasion; the protective earthing line is arranged and thickness and density differ along the cross-section of cable in the first metal screen layer, in Cost reduction, has improved shielding properties.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of electric vehicle alternating-current charging connection flat cable, comprise three power lines 001 that are set up in parallel, a neutral line 002 and two control lines 003, described power line 001, 003 of the neutral line 002 and control line are extruded with sheath 004, described sheath 004 outside is provided with the first metal screen layer 005 successively, type insulating wrapping strip 006, oversheath 007, described two control lines 003 are mutually stranded and be extruded with sheath 031, sheath 031 is outer is the second metal screen layer 032, described power line 001, the neutral line 002 is from inside to outside successively by conductor (011, 021) and insulating barrier (012, 022) form, described the first metal screen layer 005 is to form along the cross-section of cable spaced some protective earthing lines 051 successively, described protective earthing line 051 is bare copper wire, described bare copper wire is arranged loose in the arc transition section of the cross-section of cable, straightway dense arrangement at the cross-section of cable, and arc transition section place copper wire diameter is greater than straightway place copper wire diameter.The described sheath extruded 004 is at the slotting glass fibre 041 of getting one's things ready that is embedded with.Described the first metal screen layer 005 skin is coated with graphite linings 008.Described conductor (011,021) is the non-stranded core of straight line.
