Description
Technical field
The utility model relates to cable, particularly a kind of shadow data communication paired cable that blocks water of high performance signal transmission.
Background technology
The existing data communication paired cable that blocks water has various ways, its structure substantially based on dose water blocking yarn or band, profile is rounded, though its advantage is arranged, also exists following shortcoming:
The one, because filler is water blocking yarn or band, can not be stoped effectively the intrusion of moisture in the air;
The 2nd, not only increase the cable external diameter, and when wiring or termination construction, will remove water blocking yarn or band, increased the construction working amount;
The 3rd, for some moist pipeline wirings, if do not destroy original structure facility, and to introduce new high-performance data cable, if used cable can not moistureproof, waterproof, then probably run into moisture and invade, the decay of cable is sharply increased, so not only influence the life-span of cable, the delay or the error code that also can cause signal transmission to use even adopt the high-performance Digital Transmission cable also can rapid deterioration, cause unnecessary loss.
Summary of the invention
In order to solve above-mentioned built on stilts and pipeline wiring or auxilliary moistureproof and the anti-outside electromagnetic interference problem of blocking water of establishing the data communication paired cable in the place of humidity, task of the present utility model provides a kind of improved high-performance shadow data communication paired cable that blocks water, it can prevent moisture intrusion cable effectively, and anti-outside electromagnetic interference.
The technical solution of the utility model is as follows:
A kind of high-performance shadow data communication paired cable that blocks water, it comprises several conductors, at the outer insulating barrier that coats of every conductor, and ground wire, aluminium foil and oversheath, one group of twisted pair wire is formed in per two conductor twistings, two groups of above twisted pair wires are stranded, and to be arranged in a core assembly line stranded and coat sealing by polyester belt, promptly the outer surface at insulating layer of conductor is filled with greasy for preventing water in the coating layer of polyester belt, ground wire is coated in the coating layer of polyester belt, aluminium foil is the skin that screen is coated on the polyester belt coating layer, and oversheath then is coated on the skin of aluminium foil.
The high-performance of the present utility model shadow data communication paired cable that blocks water is improved from the construction of cable, it has removed traditional materials such as water blocking yarn or band of dosing, when being twisted into, online pair set fills greasy for preventing water, and increased the shielding construction design, therefore can be widely used in the termination and the comprehensive wiring aspect of equipment room.Structural design of the present utility model can prevent moisture intrusion cable effectively, even in outdoor built on stilts wiring, its block-water performance is also very superior, and meets the requirement that comprehensive wiring should be easy for installation.
Cable profile of the present utility model is rounded, and the heart yearn pair twist is arranged and filled greasy for preventing water, makes every pair of twisted pair wire all be protected, and has the moisture-proof role that better blocks water.This cable has not only reduced tradition block water the line footpath and the external form of line, and on its line footpath and external form rounding more, also needn't increase the construction working amount during wiring for removing water blocking yarn or band.The screen of this cable is made of aluminium foil strip and ground wire, has better anti-outside electromagnetic interference function, satisfies the requirement of comprehensive wiring.The mechanical performance of this cable product, digital data transmission performance and security performance such as fire-retardant all can satisfy the requirement of the aspects such as industrial standard of world developed country.
Description of drawings
Fig. 1 is the block water profile of shadow data communication paired cable of a kind of high-performance of the present utility model.
Fig. 2 is the profile of another embodiment of Fig. 1 cable.
Embodiment
Referring to Fig. 1, the utility model is a kind of high-performance shadow data communication paired cable that blocks water, and is provided with several conductors 1 in cable, every conductor 1 outer evenly coated insulation layer 2.Cable also is provided with ground wire 3, aluminium foil 4 and oversheath 5.
Per two conductor 1 twistings form that the above twisted pair wire of 6, two groups of one group of twisted pair wires 6 is stranded to be arranged in a core assembly line stranded 7 and to coat sealing by polyester belt 8.Polyester belt uses the polyester vinyl material, and thickness is 0.025mm ± 0.005mm, and width is 2.0cm ± 0.2cm.
In the coating layer of polyester belt 8, just the outer surface at insulating layer of conductor 2 is filled with greasy for preventing water 9.Ground wire 3 is coated in the coating layer of polyester belt 8.Aluminium foil 4 is the skin that screen is coated on polyester belt 8 coating layers.5 skins that are coated on aluminium foil 4 of oversheath.
Referring to Fig. 2, the requirement different according to product hierarchy can add shim 10 and be filled when twisted pair wire 6 is stranded, and installing shim 10 between the group of twisted pair wire 6 and group just is inner not collinear to having stronger anti-electromagnetic interference capability to strengthen.
By the said structure setting, form shielding of the novel band of this money and block-water performance and better transmit and use the data communication paired cable.This high-performance data communication paired cable has three important unit for electrical property parameters: decay, crosstalk and return loss, all considered this triangular harmony in design.
Because factice for filling when the heart yearn pair twist makes cable footpath can not increase, and external form more rounding help wiring.The cable block-water performance also is better than dosing water blocking yarn or band and other oil-filled mode; protected every group of twisted pair wire not invaded by moisture; even under the situation of outside run bad weather; block-water performance is also very superior; the decay of cable is affected and worsens; optimize the decay of cable, increased the useful life of cable.Add design shielding construction is arranged, the termination of having improved equipment room reaches and extraneous interference, electromagnetic field distribution when helping improving wiring, guarantee that line is to electric capacity and inductance coupling high, thereby the performance of improving return loss and crosstalking can reach transmission frequency bandwidth to 650MHz and above performance requirement.
Cable conductor of the present utility model adopts oxygen-free copper or hypoxemia copper product, can make resistance reach minimum; Insulating barrier adopts high density polyethylene (HDPE) or tetrafluoroethene and fluorine resin material, and thickness is 0.28mm ± 0.02mm, all is dielectric constant and the smaller material of dielectric loss rate.
Because the effective area that electric current flows through increases, the characteristic that the resistance of cable conductor greatly reduces, the conductor that this cable adopts can make cable when high-frequency transmission in 24AWG to 23AWG scope, increases the effective area of outermost layer around conductor region.
Cable jacket of the present utility model is made by materials such as polyvinyl chloride, tetrafluoroethene, low density polyethylene (LDPE) and fluorine resins; both guaranteed the soft of cable; cushion the pressure of cable surface again to the full extent; opposing is along the power of pullling of cable direction; make inner twisted pair wire not be subjected to external influence power and damaged or the electrical property variation; cable is played protective effect, offset the external influence factor.The oversheath fire resistance of this cable is good, also can satisfy-40 ℃ to 80 ℃ environment instructions for use.
