Embodiment
Fig. 1 is the cross section structure schematic diagram according to the high anti-interference cable of novel armouring of an embodiment of the present utility model.
As shown in Figure 1, the high anti-interference armoured cable in the present embodiment comprises from inside to outside successively: cable core 4, belting layer 5, foil shielding layer 6, drain wire 7, aluminium strip screen 8, inner restrictive coating 9, armour 10, external sheath layer 11.
In the present embodiment, cable core 4 comprises N group (N 〉=1) to line group 3, every group line group 3 is made up of by different pitches are stranded two leads 1 that are coated with insulating barrier 2, for convenience of description, has only drawn one of them among Fig. 1 to the line group.Be extruded with insulating barrier 2 outside the every lead 1, the material of insulating barrier 2 is elected polyethylene as in the present embodiment.
The cable core 4 outer belting layers 5 that are provided with, belting layer 5 outer overlapping coating foil shielding layers 6.Being provided with one deck thickness outside the foil shielding layer 6 is two-sided plastic-coated aluminium strip overlapping vertical aluminium strip screen 8 that packs behind embossing of 0.3mm.Be provided with drain wire 7 between foil shielding layer 6 and aluminium strip screen 8, this drain wire axially is provided with along cable.The aluminium strip screen 8 outer inner restrictive coatings 9 that extrude the layer of polyethylene material, the inner restrictive coating 9 outer wrapped armours 10 of serpentine ribbon spiral interlocking-type that are provided with, the armour 10 outer layer of polyethylene external sheath layers 11 that extrude.Preferably, the thickness of the wrapped armour 10 of this serpentine ribbon spiral interlocking-type is 0.1～1.0mm.
Though armour 10 adopts the wrapped armour of serpentine ribbon spiral interlocking-type as optimal selection in the foregoing description, can also adopt " square " ribbon spiral interlocking armour according to concrete application armouring mode; The material of armour can select for use other hard electric conducting material to make, and more preferably adopts hard metal material to make.The structure of the wrapped armour of serpentine ribbon spiral interlocking-type as shown in Figure 3, the structure of " square " ribbon spiral interlocking armour is as shown in Figure 4.
Outside the inner sheath of telecommunication cable, install serpentine ribbon spiral interlocking armour or " square " ribbon spiral interlocking armour additional, improve resistance to compression, the tensile property of telecommunication cable on the one hand greatly; These two kinds of armours have pliability preferably on the other hand, can guarantee that again cable has certain pliability; And, because the armour of the utility model embodiment is to be applied to telecommunication cable, the adding of armour has also brought additional interference free performance for telecommunication cable, thereby has improved the performance of telecommunication cable on the whole, has expanded the adaptable environment of telecommunication cable of the present utility model.
Among the embodiment of the present utility model, lead 1 and the drain wire 7 preferred copper cladding aluminum conductors that adopt, the structure of copper cladding aluminum conductor tightly coats copper layer 12 as shown in Figure 2 outside aluminium core 13.So both saved more rare copper resource, reduced cable cost, simultaneously because the kelvin effect of transmission signals does not influence communication quality again.Certainly, do not get rid of it and can use common copper conductor or other lead yet.
And the inner double-layer shielding structure that adopts of armour can improve the cable interference free performance more, has formed the multiple assurance to shield effectiveness.And the internal layer aluminium foil can solve when cable construction or use, in case aluminium strip screen fracture failure must be scrapped the waste that causes to inner cable protection to the end constantly.Certainly, under some special cases, do not get rid of and adopt other form screen.
In addition, according to telecommunication cable of the present utility model when the ground connection, remove armouring and sheath after, drain wire is ground connection directly, has saved the set-up time.And, generally when cable splice, remove APL aluminum plastic laminate composite sheath layer after, screen also just has been removed, and so just causes the place of continuing not have shielding protection.And according to cable of the present utility model when continuing, remove restrictive coating and unclamp aluminium foil and carry out after heart yearn continues, again aluminium foil is twined and coats the position of continuing and can recover shielding layer structure.
Although above concrete description exemplary embodiment of the present utility model, the one of ordinary skilled in the art can not break away from the multiple change of making under the spirit or scope situation of the present utility model these disclosed embodiments.Be appreciated that above-mentioned specification comprises or accompanying drawing shown in all the elements only be illustrative rather than definitive thereof.Do not breaking away under the mental condition of the present utility model that limits by appended claims, can make change in details or the structure the utility model.
