Description
Technical field
This utility model relates to a kind of control cable, particularly relates to a kind of metal armouring with metal tape spiral armor and controls cable.
Background technology
Control cable and apply to the industries such as railway traffic, energy transport and the industrial and mining establishment cable for occasions such as ac rated voltage less than 450/750 volt control, protection circuits；Therefore control cable does not require nothing more than and has reliable interference free performance, and with greater need for mechanical performances such as good resistance to compression stretch-prooves.Control outside the cable core of cable, to cover metal armor layers and can increase the mechanical strength of cable, improve erosion prevention, to strengthen the comprcssive strength of cable, tensile strength and to protect and extend the service life of cable.
Armature of cable layer generally has two kinds: wire armoring structure and steel-tape armouring structure, though the control cable of wire armoring structure can bear bigger axial tension, but wire armoring produces more difficulty, cost is high, range is limited, is often used for span relatively big, lays the occasion that drop is bigger.Steel-tape armouring structure can bear bigger warp-wise power, has good comprcssive strength, and range of application is the most extensive, in the engineering such as such as railway, high ferro, urban transportation, it is adaptable to buried, tunnel and cable installation in pipe.But existing steel-tape armouring structure mostly uses double steel band, gap around-packing technology, it is by steel band after being wrapped in and forming armor on cable core, then on armor, extrudes plastic sheath.In existing this structure, the bending of cable relies only on the deformation of steel band itself, flexible not enough, the fragile metal tape of overbending, and steel-tape armouring gap is relatively big, and once overcoat ruptures easily damage armored cable cable core.
Traditional cable that controls mostly or by heart yearn and is wrapped in what the insulating jacket layer of heart yearn outer layer was constituted; owing to lacking the shielding of the physical parameter such as mixed and disorderly electromagnetism of signal to external world; even if a least interference signal or electromagnetic interference source are it is possible to affect the reliable and secure transmission of control signal; especially to having the use occasion of high reliability for railway, high ferro etc., with greater need for having good interference free performance and steel belt protection function.
Utility model content
Technical problem to be solved in the utility model is to provide that a kind of steel band clamping is tight, cable flexibility is good, and can effectively shield the flexible screw armoured control cable of outer signals interference.
In order to solve above-mentioned technical problem, flexible armoring of the present utility model controls cable, including cable core, this cable core includes some insulation core wires, described cable core is coated with belting layer, screen layer and inner sheath the most successively, inner sheath is closely wound with the steel-tape armouring layer being made up of armouring tape, this steel-tape armouring layer is extruded with outer jacket；One side of described armouring tape is provided with grafting draw-in groove, another side of armouring tape is provided with grafting tenon, the cross section of grafting draw-in groove is the semicircle of indent, and the cross section of grafting tenon is the semicircle of evagination, and this grafting draw-in groove is corresponding with the cross sectional shape of grafting tenon to coincide.
After using said structure, owing to the dual-side of armouring tape is respectively arranged with the mutually identical corresponding grafting draw-in groove of shape and grafting tenon, and the equal semicircular in shape of cross sectional shape of grafting draw-in groove and grafting tenon, the grafting tenon card of circular strip inserts in that formed in the card slot that shape is coincide can being hinged with relative motion bending, not only make steel-tape armouring layer can carry out curving folding in a big way dynamic, thus enhance the flexibility of cable, facilitate laying and using of cable, make the range of application of cable significantly expand.Also due to steel-tape armouring steel band have employed this card inserting structure, steel band clamping is tight, eliminates the joint gap of armouring tape, makes armor that cable and cable can be played more efficiently protective effect.Due also to be provided with screen layer between belting layer and inner sheath, effectively intercept the interference to controlling cable of external electromagnetic field and the signal of telecommunication, it is achieved the safe and reliable transmission of control signal, also enhance insulating properties and the barrier propterty controlling cable.
Preferred implementation of the present utility model, the section radius of described grafting tenon is R1, and the section radius of the grafting draw-in groove in semicircle groove is R2, R1=(1.00 1.05) R2.This structure can realize the clamping that armouring tape is tighter.
Further embodiment of the present utility model, described armouring tape is provided with elastic groove, is provided with stress dispersion slot in the inner of elastic groove, and this elastic groove is positioned at the bottom land position of grafting draw-in groove.Arranging of elastic groove provides grafting elastic force to the mutual clamping of armouring tape so that connect relatively reliable；Stress dispersion slot effectively prevent stress and concentrates the damage to steel band.
Preferred implementation of the present utility model, described armouring tape is provided with the slot circular bead surface of introversion, and this slot circular bead surface is positioned at the notch both sides of grafting draw-in groove, 20 °, leaning angle α=10 ° of slot circular bead surface.Being provided with the tenon circular bead surface of introversion on described armouring tape, this tenon circular bead surface is positioned at the tenon bar both sides of grafting tenon, 20 °, introversion angle beta=10 ° of tenon circular bead surface.The slot shoulder being obliquely installed and tenon shoulder increase the flexion degree of freedom between grafting steel band, and the raising of cable flexibility has been effectively ensured.
Further embodiment of the present utility model, described screen layer is proof copper-wire braided screen layer.Proof copper-wire braided layer not only shield effectiveness is good, and flexibility is good.
Further embodiment of the present utility model, described inner sheath is that polyethylene extrudes layer.Having good ageing-resistant and insulating properties, flexibility might as well.
Further embodiment of the present utility model, described outer jacket is extruded by low smoke halogen-free flame-retardant polyolefin and forms.This structure has higher combustion protection effect.
Further embodiment of the present utility model, is provided with gasket for packing in described cable core.Gasket for packing can not only strengthen the tensile strength of cable.And make the construction of cable stablize rounding.
