Embodiment
The utility model discloses a kind of 7 core alternating-current charging cable for electric automobiles, there is Stability Analysis of Structures, outward appearance rounding, resistance to bending, resistance to pulling.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-Fig. 4, the 7 core alternating-current charging cable for electric automobile cable core function diagrams that Fig. 1 provides for the utility model embodiment; The structure chart of the 7 core alternating-current charging cable for electric automobiles that Fig. 2 provides for the utility model embodiment; The control that Fig. 3 provides for the utility model embodiment be connected the composition diagram of confirming core unit; The control that Fig. 4 provides for the utility model embodiment be connected the structure chart of confirming core unit.
The 7 core alternating-current charging cable for electric automobiles that the utility model embodiment provides, comprise by conductor wire core, function core and fill the charging cable cable core that 3 stranded after-applied lapping layers 4 form, and being arranged on the restrictive coating 5 of charging cable cable core outside; Conductor wire core comprises AC power core (L), neutral core (N), protective earthing core (PE) and spare extension core (NC1, NC2); Function core comprises that the control confirmation core (CP) being made up of with insulating barrier 12 conductor 11 is connected and confirms core (CC) with charging, controls confirmation core (CP) and confirms the stranded after-applied screen 13 composition function cores of core (CC) with charging with being connected; Its core improvement is, charging cable cable core also comprises the center-filled core 6 of the core that is arranged on charging cable cable core, and each conductor wire core and function core are evenly arranged in around it, shown in its structure can see figures.1.and.2.
Can find out from above-mentioned technical scheme, the 7 core alternating-current charging cable for electric automobiles that the utility model embodiment provides, by being arranged on the center-filled core 6 of core of charging cable cable core, each conductor wire core and function core are evenly arranged in around it, there is Stability Analysis of Structures, outward appearance rounding, resistance to bending, resistance to pulling.
In this programme preferred embodiment, center-filled core 6 adopts fiber material or wire to extrude the material formation identical with restrictive coating 5 outward.
In order further to optimize above-mentioned technical scheme, screen is three layers, is followed successively by from the inside to the outside vertical alclad plastic composite strip screen 131, copper wire or tinned copper wire woven shield 132 and protective layer 133.
Its three layers of shielding layer structure designs have the following advantages:
1, vertical alclad plastic composite strip screen 131 and copper wire or tinned copper wire woven shield 132 form double layer screen layer, have strengthened the anti-electromagnetic interference capability of cable, have guaranteed the accuracy of cable communication signal, have improved the reliability of cable charging.
2, indulge alclad plastic composite strip screen 131 except function of shielding, the effect that also has defencive function core not to be destroyed.Because the working method of charging electric vehicle cable determines the External Force Actings such as it stands to move back and forth for a long time, pulling, these External Force Actings easily cause the impacts such as distortion, fracture, insulating barrier cut on the each core of cable, thereby make cable failure.In whole cable, function core specification minimum, insulation the thinnest, be vulnerable to most mechanical external force destroy, need lay special stress on protecting.Aluminium-plastic tape used herein has good mechanical strength, pliability and less coefficient of friction, can confirm that core carries out omnibearing protection to communication connection, extends its useful life.
3, protective layer 133 not only can make can keep preferably between screen and insulating barrier 22, restrictive coating 5 slipping property relatively; also can make the broken end copper wire of restrictive coating 5 not conductively-closed layers or tinned copper wire destroy insulating barrier 22, restrictive coating 5, thereby improve cable useful life.
In order further to optimize above-mentioned technical scheme; the metal covering of vertical alclad plastic composite strip screen 131 arranges inwardly; it is its side away from copper wire or tinned copper wire woven shield 132; with better anti-electromagnetic interference and the physical protection effect that must play internal core, avoid destroying external structure simultaneously.
In the specific embodiment providing at this programme, protective layer 133 adopts teflin tape.Because teflin tape has self lubricity and good mechanical performance; teflin tape protective layer 133 not only can make can keep preferably between screen and insulating barrier 22, restrictive coating 5 slipping property relatively; also can make the broken end copper wire of restrictive coating 5 not conductively-closed layers or tinned copper wire destroy insulating barrier 22, restrictive coating 5, thereby improve cable useful life.
Fill the preferential fire-retardant gasket for packing formation that adopts, lapping layer preferentially adopts fire-retardant twining package tape to form.
Conductor adopts and meets the 5th kind or the 6th kind of zinc-plated or stranded the forming of non-zinc-plated oxygen-free copper conductor that GB/T3956 requires.It is that the ethylene-propylene rubber mixture of 90 ℃ or TPE thermoplastic elastomer extrude and form that insulating barrier adopts long-term work temperature.It is that any of the chlorosulfonated polyethylene rubber of 90 ℃ or other suitable synthetic elastomers, TPE thermoplastic elastomer, TPU polyurethane elastomer extrudes and form that the coat layer of power cable (as shown in Figure 2) adopts with the long-term work temperature that matches of insulation, guarantees that cable has high temperature resistant, fire-retardant, wear-resisting, resistance to bending, the excellent properties such as ageing-resistant.In the time having environmental-protecting performance requirement, insulation, filling, lapping layer, restrictive coating all adopt the feature of environmental protection material that meets the ROHS of European Union command request.
It is 690V that this product is applicable to ac rated voltage maximum, rated current is no more than 250A(AC) being connected of electric vehicle charging jockey and conduction-type charging inlet used for electric vehicle, the connection when being applicable to special charging station and using non-Vehicular charger to charging electric vehicle and the connection of electric road vehicle charging device.Also connection when applicable family or public place use the power supply unit of configuration to provide power source charges for electric automobile.
In sum, the 7 core alternating-current charging cable for electric automobiles that the utility model embodiment provides, center-filled core adopts fiber material or wire to extrude the material formation identical with restrictive coating outward, each function core is evenly arranged in around it, has advantages of Stability Analysis of Structures, outward appearance rounding, resistance to bending, resistance to pulling.
