Abstract
The utility model discloses a novel armour wideband digital cable belonging to transmission carrier range of digital communication, comprising conductors made of copper wires or tinned copper conductors from inner to outer, wherein materials extruded on the outside of the conductor is the insulation layer made of polythene, two insulation cores are stranded into a twin according to different pitches, and a plurality of twins constitutes the cable core; overlapping materials on the outside of the cable core are an inner belting layer made of polyester belts, and a screen layer is covered on the outside of the inner belt. An outer belting layer is extruded at the outside of the screen layer, and an inner sheath layer is extruded on the outside of the outer belting layer. A continuous interlocking type metal armour layer in a spirrillum is arranged on the outside of the inner sheath layer. An outer sheath layer is arranged on the outside of the armour layer. The utility model furthermore increases anti-electromagnetic interference of the cable, ensures distinct transmission of the transmission signals, also has higher tensile, compression resistance and better flexibility.
Description
Technical field
The utility model belongs to the cable technology field, relate in particular to a kind of have anti-open, the armouring wideband digital cable of resistance to compression and flexibility.
Background technology
Along with the high speed development of modern communications cause, the popularization of digital communication and information superhighway, the use of wideband digital cable is more and more.Therefore the use occasion of data cable also becomes increasingly complex, as under indoor carpet, in wall corner and the wild environment laid processes, unavoidable cable formation born the requirement of trampling, push, stretching, and has resistance to compression preferably, tensile strength, reaches flexibility preferably.And present digital cable can't reach above requirement.
Summary of the invention
The purpose of this utility model is not have resistance to compression preferably, tensile strength in order to solve present wideband digital cable, and the requirement of flexibility preferably, can't reach bear trample, push, the requirement of special occasions such as stretching, the utility model provides a kind of novel armouring wideband digital cable.
The technical solution of the utility model is that a kind of novel armouring wideband digital cable comprises: interior belting layer, screen, outer belting layer, inner restrictive coating, armour, external sheath layer that conductor, conductor outsourcing insulating layer coating, cable core, cable core coat outward successively.It is characterized in that: extrude a hdpe layer insulating barrier outside copper or tin-coated copper conductor, two thoroughly do away with the edge lead forms one to the line group by the stranded back of different pitches.Then by some to the line group by rearranging cable conductor in order, band in the outer overlapping wrapped polyester belt of cable core, interior band coats screen outward, the overlapping more outward wrapped outer band of polyester belt that covers of screen, outer band extrudes the polyvinyl chloride with environmental protection flame retardant or the inner restrictive coating of TPU protective cover material outward, inner restrictive coating is outside equipped with the metal armouring layer, and armour extrudes the polyvinyl chloride with environmental protection flame retardant or the external sheath layer of TPU protective cover material outward again.
The internal layer of described screen is the overlapping coating of two-sided aluminium foil, coats braiding copper cash or tinned wird outside aluminium foil.
Described armour is that serpentine ribbon spiral interlocking-type is wrapped.
The beneficial effects of the utility model are: further improved the anti-electromagnetic interference capability of cable, guaranteed the clear transmission of transmission signals, have again higher anti-ly open, resistance to compression and softness preferably.
Description of drawings
Fig. 1 is the cross section structure schematic diagram of novel armouring wideband digital cable.
Number in the figure:
The 1-conductor; The 2-insulating barrier; 3-is to the line group; Belting layer in the 4-; The two-sided aluminium foil of 5--; The 6-braid; The outer belting layer of 7-; The 8-inner restrictive coating; The 9-armour; The 10-external sheath layer.
Embodiment
The utility model provides a kind of novel armouring wideband digital cable, Figure 1 shows that the cross section structure schematic diagram of novel armouring wideband digital cable.Comprise from inside to outside: the thread conductor 1 of copper cash or tin-coated copper, the conductor 1 outer insulating barrier 2 that extrudes polythene material, two thoroughly do away with the edge cores forms one to line group 3 by the stranded back of different pitches, by shown in Figure 14 or more to line group 3 by rearranging cable core in order; The interior belting layer 4 of the outer overlapping wrapped two layers polyester carrying material of cable core.The interior belting layer 4 outer two-sided aluminium foil 5 of overlapping coating and the composite shielding layers of copper cash or tinned wird braid 6 compositions of being provided with.The outer belting layer 7 of the outer overlapping more wrapped one deck polyester belt material of screen; Extrude one deck outside the outer belting layer 7 and have the flexible PVC of environmental protection flame retardant or the inner restrictive coating 8 of TPU urethane jacking, the inner restrictive coating 8 outer wrapped armours 9 of serpentine ribbon spiral interlocking-type that are provided with extrude one deck again outside the armour 9 and have the flexible PVC of environmental protection flame retardant or the external sheath layer 10 of TPU urethane jacking.
Armour 9 of the present utility model is that serpentine ribbon spiral interlocking-type is wrapped, plays anti-, resistance to compression effect on the one hand, the protection cable core; Serpentine steel band interlocking armouring has pliability preferably on the other hand, does not influence the cable pliability; Moreover armour can advance a shield effectiveness that plays cable, improves the anti-electromagnetic interference performance of cable.This Applied Materials does not all contain harmful substances such as lead, the many bromides of cadmium, meets requirements of green environmental protection.
