Embodiment
Further specify the embodiment of the utility model below in conjunction with accompanying drawing.
Like Fig. 2, Fig. 3, Fig. 4, shown in Figure 5; A kind of safety of the utility model is held lotus type ground and is moved and use cable, and it comprises: be arranged side by side in the inner many root functionalitys line of said cable, extrude between said functional line and the outside or wrapped in the sheath 18 in the said functional line outside, be located at metal screen layer 32, insulation band 35, the oversheath 38 in said sheath 18 outsides successively; Said functional line comprises one to three power line 10, a center line 30, and the cross section of said cable is a flat.Said power line 10 is also claimed phase line.Power line 10 comprises conductor 12 and insulating barrier 15.
Functional lines such as power line 10 are placed the inside of cable; Around functional line, fill or be provided with wrapping up sheath 18; Set gradually metal screen layer 32 and oversheath 38 etc. again, connect to form shielding harness, keep apart internal core and outside fully through earth connection and metal screen layer 32; Anti-stop signal disturbs and can prevent electric leakage, thereby can guarantee the safety of personnel and equipment.Wherein comprise power line 10 and center line 30 in the functional line, make safety hold lotus type ground and move with cable and have safe good electric power conveying function.
It is flat that functional line flat raft setting in the charging cable makes the charging cable cross section, makes that the cable overall sectional is long-pending to diminish, thereby saves raw material and alleviate the weight of cable.Simultaneously; Compare with the circular cross-section cable, it is the plane that the flat cable is placed on the pressure that bears on the plane, and the whole cable lifting surface area increases, stressed even distribution; Therefore flat cable can improve the grinding pressure that it can bear in the plane; Can improve product and roll ability, improve the grinding pressure that it can bear in the plane, can reduce impulsive force when vehicle rolls and can bear the pressure in the certain limit anti-.This cable is used for moving occasion temporarily carries out electric power transfer, have the ability that safety is held lotus, can satisfy and trample the requirement that rolls.。
More preferably, the core of said power line 10 is non-stranded core, and this non-stranded core comprises the interlacing layer 55 of the many craspedodrome plain conductors 50 that extend in parallel, the said craspedodrome plain conductor 50 of parcel, with reference to shown in Figure 1.Common cable is general to adopt stranded core to make, and twists easily in the process of using, and causes distortion of the cable, thereby influences electric power transfer, influences cable useful life.Adopt non-stranded core, be different from common stranded core, non-stranded core has torsional resistance preferably; Can there be twisted phenomena; Increased the tensile property of product simultaneously, prolonged the useful life of producing cable, especially be suitable for using as the cable that moves occasion.Use the tissue of interlacing that craspedodrome plain conductor 50 is closely wrapped up together, the cable of formation has better torsional property.The outer braiding structure that adopts, core can effectively promote the stretch-proof ability of cable after combined crosswise.
Certainly, the core of power line also can use conventional stranded core, and the direction of lay of its two cores can produce anti-twist ability on the contrary.Conventional stranded core is convenient to buying, is manufactured simply, and cost is low.
More preferably, said craspedodrome plain conductor 50 is metallic conductor or the conductor with coat of metal, makes lead have the electric conductivity of lead conductor, has the torsional property of rigidity simultaneously.
More preferably, said cable comprises the said interlacing layer 55 of multilayer, according to the quantity and the big or small pliable and tough gripping sleeve that multilayer binding can be set of craspedodrome plain conductor 50, lead is closely wrapped up, and further improves the torsional property and the electric conductivity of cable.
More preferably, said metal screen layer 32 comprises many equally distributed shielding conductors 33 of the said cable cross-section in edge, and said shielding conductor 33 twines side by side or weaves and is wound in said sheath 18 outsides, and said shielding conductor 33 conducting is each other formed earth connection.Can shielding protection be provided for charging cable around the functional line metal screen layer 32 that shielding conductor 33 forms of evenly arranging; The interference that leaks of anti-stop signal; Also prevent the message transmission of external signal interference signal control line, prevent that simultaneously power line from gushing interference signal, also prevent the power line electric leakage.
More preferably, said shielding conductor 33 is bare copper wires, and bare copper wire has good ductility, and is evenly distributed as screen, can prevent that the part from breaking or fracture and lose function of shielding.
More preferably, said oversheath 38 is oblate type along the cross section of cable widths direction, makes cable formation flat and both sides for semicircle, roll thereby can bear, and cable thickness direction two sides can need not to differentiate direction as the one side of pasting ground.
More preferably; Said oversheath 38 outsides are provided with dihedral support edge 25 along the cable length direction; Said dihedral support edge is arranged at the two ends of a side of cable widths direction, and promptly the cross section of cable is half oval type half rectangle, and side two ends of its Width are right angle or acute angle for the rounding opposite side.When 25 cross sections, dihedral support edge were acute angle, the cross section of cable was that the top is the trapezoidal of fillet.Side with dihedral support edge 25 should be provided with pasting, and cable is played the supplemental support effect, improves cable and holds lotus ability and the anti-ability that rolls.
The insulating layer material of cable core can adopt fluoroplastics or polyether-ketone to extrude, and makes insulating barrier reach certain rigidity, has higher coefficient of safety.The material of its sheath and oversheath adopts rubber and plastic mixture or synthetic rubber, makes it have certain rigidity rather than simple soft sensation, and the cable general structure is flat, personnel is trampled feel safe in the above with comfortable.
The above disclosed preferred embodiment that is merely the utility model can not limit the interest field of the utility model certainly with this, so according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
