Description

A kind of super Category 5, Shielded netting twine

Technical field

The utility model is related to communication cable construction applications, in particular to a kind of super Category 5, Shielded netting twine.

Background technology

At present, network transmission is increasingly flourishing, and in today of scientific progress, everyone be unable to do without network.Network layout and Message exchange equipment realizes extending in all direction for network.

Surpass the multimedia wire rod that five class netting twines are the telematic services such as a kind of propagation data, speech, be widely used in In the broadband access engineering such as broadband customer premises network, the quality of its quality is directly connected to the transmission quality of information communication.In order to The interference of signal is reduced, surpasses each line in five class netting twines to mutually being turned round around forming by the copper conductors of two eradication edge, and It is not collinear to different torsion winding degree (be exactly turn round coiling quantity) in same cable.Meanwhile, surpass five class netting twines Line in cable to be turned round counterclockwise around.But there is many and ask in the cable of some informal manufacturer's productions Topic:1. in order to simplify manufacturing process, in cable the torsion of wired pair it is identical around density;2. the torsion of two insulated conductors of line centering around Density does not meet technical requirements;3. the torsion of line pair is undesirable around direction.If there is problem above, it will cause network line Near-end cross (referring to the signal annoyance level between two lines pair in UTP) so that transmission range does not reach requirement.The torsion of netting twine Winding degree has aborning stricter standard, when actually choosing, can be carried out with some professional equipments in the case of conditional Measure, but general user can only observe with naked eyes.It should be noted that, the torsion winding degree of five class UTP center lines pair is closeer than three classes, surpasses Five classes are closeer than five classes.And in order to prevent netting twine internal and external interference, improve the stability of information transmission and prevent eavesdropping, except non-screen Cable is covered, also there is on the market the shielded cable for being provided with screen layer.

The insulating protection material high temperature resistant of super Category 5, Shielded netting twine employing general on the market at present, fire protecting performance are poor, And it is easily aging, the stability of signal transmission is easily affected, increased maintenance cost, it is therefore desirable to provide a kind of durability higher Super Category 5, Shielded netting twine meeting era development needs.

Utility model content

Solve the above problems, improve the performance and service life of cable, there is provided a kind of super Category 5, Shielded netting twine.

A kind of super Category 5, Shielded netting twine, including the inner conductor, screen layer and insulation shield that sequentially coaxially arrange from inner side Set, the inner conductor has a plurality of twisted-pair feeder, and the twisted-pair feeder is made by twisting counterclockwise by two conductor metal silks, described to lead Inner insulating layer is enclosed with outside body wire, the inner insulating layer is made up of cross-linking radiation PE.

Further, it is provided with earth lead between the inner conductor and screen layer.

Further, the screen layer is drawn into by aluminium foil wheat.

Further, the insulating sheath is made up of cross-linking radiation PE.

Further, the conductor metal silk is made using tin-coated copper.

The utility model has the advantage of, advantages of good shielding performance, high temperature resistant, flameproof effect are strong, also do not release substantially in burning Put harmful substance, and service life is longer, can effective guarantee network signal transmission quality, reduce network operation cost.

Description of the drawings

In order to be illustrated more clearly that the utility model embodiment or technical scheme of the prior art, below will be to embodiment Or the accompanying drawing to be used needed for description of the prior art is briefly described, it should be apparent that, drawings in the following description are only It is some embodiments of the present utility model, for those of ordinary skill in the art, in the premise for not paying creative work Under, can be with according to these other accompanying drawings of accompanying drawings acquisition.

Fig. 1 is structural representation of the present utility model.

Specific embodiment

Poor for general cable its insulating barrier high temperature resistant, fire protecting performance, overload capacity is weaker, and service life cannot ensure Problem, there is provided a kind of super Category 5, Shielded netting twine.

Make purpose, technical scheme and the advantage of the utility model embodiment clearer, below in conjunction with the utility model Accompanying drawing in embodiment, carries out clear, complete description, it is clear that described to the technical scheme in the utility model embodiment Embodiment be a part of embodiment of the present utility model, rather than the embodiment of whole.Based on the enforcement in the utility model Example, the every other embodiment that those of ordinary skill in the art obtain under the premise of creative work is not made belongs to this The scope of utility model protection.

As shown in figure 1, a kind of super Category 5, Shielded netting twine, including the inner conductor 1, shielding that sequentially coaxially arrange from inner side Layer 2 and insulating sheath 3, the inner conductor 1 has a plurality of twisted-pair feeder, and the twisted-pair feeder is counterclockwise by two conductor metal silks 11 It is made by twisting, the conductor metal silk 11 is outer to be enclosed with inner insulating layer 12, and the inner insulating layer 12 is made up of cross-linking radiation PE, Earth lead 4 is provided between the inner conductor 1 and screen layer 2.

Further, the screen layer 2 is drawn into by aluminium foil wheat.

Further, the insulating sheath 3 is made up of cross-linking radiation PE.

Further, the conductor metal silk 11 is made using tin-coated copper.

The utility model has the advantage of, advantages of good shielding performance, high temperature resistant, flameproof effect are strong, also do not release substantially in burning Put harmful substance, and service life is longer, can effective guarantee network signal transmission quality, reduce network operation cost.

Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to Identification is of the present utility model to be embodied as being confined to these explanations, i.e., all to make impartial change and modification according to the application scope, All should still belong in the utility model covering scope.
