Description
Technical field
The utility model relates to one and surpasses the two aluminium foil of five classes and indulge bag shadow data cable.
Background technology
Along with the continuous progress of network technology, more and more higher to the cable needs of signal transmission, to having higher requirement of the interference performance of cable anti-electromagnetic wave.Therefore the data cable shielded due to its shielding properties superior, developed rapidly, extensive use in aggregation of data wiring system.The multiplex single screen of current shielding super category 5 cable is covered, and fragile aluminium foil when single shielded type cable removes sheath, shield effectiveness is poor.Braiding adds the high expensive of the screened cable of aluminium foil, and easily causes cable core structure to fluctuate during braiding, affect transmission performance, and it is low to weave process efficiency, causes production efficiency to be lowered, and braided wires cost is higher simultaneously, and Heavy Weight.
Utility model content
The utility model mainly solves the technical problem existing for prior art, thus provides that a kind of good airproof performance, production efficiency are high, transmission performance is excellent, shield effectiveness is good, production cost is low, and bag shadow data cable indulged by the lightweight two aluminium foil of five classes that surpasses.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
One of the present utility model surpasses the two aluminium foil of five classes and indulges bag shadow data cable, and described cable structure is from the inside to the outside followed successively by conductor, insulation, twisted pair wire, polyester belt, internal layer aluminium foil, drain wire, outer foil, tears rope and oversheath; Described twisted pair wire has four groups, and often group is made up of a pair twisted-pair feeder, and four groups are twisted into as cable core to twisted-pair feeder; Described cable core is vertical to be wrapped in internal layer aluminium foil, forms the airtight tubular structure of ground floor and first longitudinal covering model; Described drain wire is arranged on the outside of internal layer aluminium foil; Described drain wire and internal layer aluminium foil are indulged and are wrapped in outer foil, form second longitudinal covering model.
As preferably, described polyester belt drags bag, makes cable core bundle be combined formation rock-steady structure.
As preferably, described drain wire is the zinc-plated drain wire of diameter 0.4 ~ 0.6mm.
As preferably, described internal layer aluminium foil is one side aluminium foil, and aluminium lamination outwardly.
As preferably, the aluminium lamination of described outer foil, is close to the aluminium face of drain wire and internal layer aluminium foil inwardly, forms the tubular structure that the second layer is airtight.
The beneficial effects of the utility model are: indulge bag shadow data cable define twice longitudinal covering model owing to surpassing the two aluminium foil of five classes, add man-hour can be directly one-body molded, without the need to separately operation, not only significantly improve production efficiency, also allow the sealing of cable be improved, also allow the transmission performance of cable be improved simultaneously; Two-layer airtight tubular structure, when improving the sealing of cable further, also form the effect structure of double shield, more promotes and stabilizes the shielding properties of cable; In addition, this kind of cable all adopts aluminium foil to shield, and this reduces the weight of production cost and cable itself.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
To be that the utility model is a kind of surpass the cutaway view that bag shadow data cable indulged by the two aluminium foil of five classes to Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection range of the present utility model
As shown in Figure 1, one surpasses the two aluminium foil of five classes and indulges bag shadow data cable, and described cable structure is from the inside to the outside followed successively by conductor 2, insulation 3, twisted pair wire 1, polyester belt 4, internal layer aluminium foil 5, drain wire 7, outer foil 6, tears rope 9 and oversheath 8; Described twisted pair wire 1 has four groups, and often group is made up of a pair twisted-pair feeder 1, and four groups are twisted into as cable core (not shown) to twisted-pair feeder 1; Described cable core is vertical to be wrapped in internal layer aluminium foil 5, forms the airtight tubular structure of ground floor and first longitudinal covering model; Described drain wire 7 is arranged on the outside of internal layer aluminium foil 5; Described drain wire 7 wraps in outer foil 6 with internal layer aluminium foil 5 is vertical, forms second longitudinal covering model.
Described polyester belt 4 drags bag, makes cable core bundle be combined formation rock-steady structure.Described drain wire 7 is the zinc-plated drain wire of diameter 0.4 ~ 0.6mm.Described internal layer aluminium foil 5 is one side aluminium foil, and aluminium lamination outwardly.The aluminium lamination of described outer foil 6, is close to the aluminium face of drain wire 7 and internal layer aluminium foil 5 inwardly, forms the tubular structure that the second layer is airtight.
This kind of surpasses the two aluminium foil of five classes and indulges bag shadow data cable, and before oversheath 8 extrusion molding, stranded good cable core is passed through first longitudinal covering model, wrap one deck internal layer aluminium foil 5, aluminium lamination outwardly.Internal layer aluminium foil 5 is wrapped in cable core and forms airtight tubular structure outward, and the zinc-plated drain wire 7 of a 0.4 ~ 0.6mm is added on the outside of internal layer aluminium foil 5, plays the effect of drainage, then enters second longitudinal covering model together.The aluminium lamination of outer foil 6, is close to the aluminium face of drain wire 7 and internal layer aluminium foil 4 inwardly, and form the tubular structure that the second layer is airtight, three-layer metal plays good ground connection, drainage, shield effectiveness.Outer foil 6 is coated, and well tearing rope 9 with same enters extrusion head later, squeezes into oversheath 8, completes processing.
The beneficial effects of the utility model are: indulge bag shadow data cable define twice longitudinal covering model owing to surpassing the two aluminium foil of five classes, add man-hour can be directly one-body molded, without the need to separately operation, not only significantly improve production efficiency, also allow the sealing of cable be improved, also allow the transmission performance of cable be improved simultaneously; Two-layer airtight tubular structure, when improving the sealing of cable further, also form the effect structure of double shield, more promotes and stabilizes the shielding properties of cable; In addition, this kind of cable all adopts aluminium foil to shield, and this reduces the weight of production cost and cable itself.
The above, be only embodiment of the present utility model, but protection range of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection range of the present utility model.Therefore, the protection range that protection range of the present utility model should limit with claims is as the criterion.
