Description
Technical field
The utility model relates to field of cable technology, more specifically to the anti-extrusion composite cable of one.
Background technology
Along with the development of society, also more and more higher to the performance requirement of cable, especially in the environment that some applying pressures are larger, can mutually extruding between the wire of cable inside, cause cable core to deform even disconnected core, the unimpeded of electric power and communication can not be ensured; In addition, existing cable interference free performance is also more weak, and when being subject to external electromagnetic interference, the electric power of cable and communication transfer are also subject to certain obstruction.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of anti-extrusion composite cable, to solve the problems of the technologies described above.
The anti-extrusion composite cable of the one that the utility model proposes, comprise cable core, described cable core comprises the first wire and four the second wires and four buffering cores, first wire comprises the first conductor being positioned at middle part and the first insulating barrier being coated on the first conductor outside, second wire has elliptic cross-section, itself and the first wire are circumscribed, adjacent second wire mutually against, and distribute in the form of a ring around described first wire axis, second wire comprises the second conductor being positioned at middle part and the second insulating barrier being coated on the second conductor outside, buffering core comprises three pieces of arcs that head and the tail connect, it is arranged between the first wire and the second wire, and with the first wire and the second wire periphery against, flexible filler is filled with between second wire, described cable core is made to have circular cross-section, described cable core outside is coated with metallo-plastic composite band lapping layer, and its metal level opposed plastic layer is away from described cable core, and metallo-plastic composite band lapping layer outside is coated with screen, and screen outside is coated with low-smoke halogen-free polyolefin restrictive coating.
Preferably, flexible filler is provided with multiple louvre along its length.
Preferably, screen is albronze braid.
Preferably, the first insulating barrier and the second insulating barrier all adopt polythene material to make.
The anti-extrusion composite cable of the one that the utility model proposes, the design of described cable core structure, makes the construction of cable more regular, and comparatively common cable ampacity is higher; When being subject to External Force Acting, the deformation of buffering core can be relied on to lay down most of stress, and crush resistance strength is high; The flexible filler be filled between the second conductor is also conducive to the crush resistance strength strengthening cable, and it offers the heat dispersion that louvre effectively enhances cable, and in the unit interval, radiating efficiency is higher; In addition, while genus plastics composite band lapping layer lapping layer plays wrapped effect, also screen coordinates, and achieve the Double-protection of this cable to electromagnetic interference, interference free performance is superior.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of anti-extrusion composite cable that the utility model proposes.
Embodiment
As shown in Figure 1, Fig. 1 is the structural representation of a kind of anti-extrusion composite cable that the utility model proposes
With reference to Fig. 1, the anti-extrusion composite cable of the one that the utility model proposes, comprise cable core, described cable core comprises the first wire 1 and four the second wires 2 and four buffering cores 3, first wire 1 comprises the first conductor 11 being positioned at middle part and the first insulating barrier 12 being coated on the first conductor 11 outside, second wire 2 has elliptic cross-section, itself and the first wire 1 are circumscribed, adjacent second wire 2 mutually against, and distribute in the form of a ring around described first wire 1 axis, second wire 2 comprises the second conductor 12 being positioned at middle part and the second insulating barrier 12 being coated on the second conductor 12 outside, buffering core 3 comprises three pieces of arcs that head and the tail connect, it is arranged between the first wire 1 and the second wire 2, and with the first wire 1 and the second wire 2 periphery against, flexible filler 4 is filled with between second wire 2, described cable core is made to have circular cross-section, described cable core outside is coated with metallo-plastic composite band lapping layer 5, and its metal level opposed plastic layer is away from described cable core, and metallo-plastic composite band lapping layer 5 outside is coated with screen 6, and screen 6 outside is coated with low-smoke halogen-free polyolefin restrictive coating 7.
In such scheme, the design of described cable core structure, makes the construction of cable more regular, and comparatively common cable ampacity is higher; When being subject to External Force Acting, the deformation of buffering core 3 can be relied on to lay down most of stress, and crush resistance strength is high; The flexible filler be filled between the second conductor 2 is also conducive to the crush resistance strength strengthening cable, and it offers the heat dispersion that louvre 9 effectively enhances cable, and in the unit interval, radiating efficiency is higher; In addition, while genus plastics composite band lapping layer 5 lapping layer plays wrapped effect, also screen 6 coordinates, and achieve the Double-protection of this cable to electromagnetic interference, interference free performance is superior.
Screen 6 is albronze braid, and while guarantee shielding properties, cable quality is lighter.
First insulating barrier 12 and the second insulating barrier 22 all adopt polythene material to make, and good insulation preformance, thermoplastic property is good.
The anti-extrusion composite cable of the one that the utility model proposes, ampacity is large, and crush resistance strength is high, strong anti-interference performance, stable signal transmission.
The above; be only the utility model preferably embodiment; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and utility model design thereof and replace or change, all should be encompassed within protection range of the present utility model.
