Abstract
The invention discloses a ship used digital communication cable characterized by low-smoke, halogen-free, and flame-retardant, and belongs to the technical field of cables. The digital communication cable comprises four pairs of twisted pair wires which are separated by a cross; the twisted pair wires are correspondingly arranged inside four quadrants separated by the cross; a polyester belt is longitudinally packaged on the twisted pair wires and the cross; an aluminum foil inner shielding layer longitudinally packages the polyester belt; a cross flow conductor, which is in contact with the aluminum foil inner shielding layer, is arranged on the inner side of the aluminum foil inner shielding layer, an inner sheath is arranged outside the aluminum foil inner shielding layer; an outer shielding layer, which is formed by weaving copper wires, is arranged outside the inner sheath; and an outer sheath, which is made from a non-halogen material, is arranged outside the outer shielding layer. The cable has double shielding effects, so that the shielding effect thereof is better; the cross flow conductor can be earthed, thereby preventing electromagnetic signals generated inside from interfering other electronic equipment; and the cross is arranged for reducing mutual signal interference between the twisted pair wires. The digital communication cable has the advantages of good anti-electromagnetism interference performance, and little distortion during transferring the signals, and can be applied to data communications for ships.
Description
Technical field
The present invention relates to a kind of cable, the telecommunication cable that particularly a kind of naval vessel is used.
Background technology
In the prior art, a kind of light-duty control peculiar to vessel, telecommunication cable are arranged, its patent No. is: ZL 03210070.1, its structure mainly comprises the screen and the outer protecting pipe of screen of the many groups of parcel conductor, every group of conductor is made up of single heart yearn or double joint heart yearn, each heart yearn has an insulating barrier outward, and described insulating barrier is the cross-linked polyolefin of thickness 0.3～0.4mm, and described conductor has the polyester insulated film of one deck outward.This cable is in light weight, has alleviated the weight on naval vessel morely, has relatively improved the speed of a ship or plane, has reduced the speed-raising cost; When ignition of cable, can stop propagation of flame, human body is not exerted an influence, and metal and electric equipment are not produced corrosion.Its weak point is: as cable for telecommunication of ships, and the antijamming capability deficiency of this cable, simultaneously, the electromagnetic interference of its generation is disturbed other electronic equipments easily.
Summary of the invention
The purpose of this invention is to provide a kind of low-smoke halogen-free flame-retardant digital communication cable for ship, make the antijamming capability of cable stronger, simultaneously, can also avoiding to external world, electronic equipment produces interference.
The object of the present invention is achieved like this: low-smoke halogen-free flame-retardant digital communication cable for ship, comprise four pairs of twisted pair wires separating mutually via cross, each twisted pair wire correspondence is arranged in four quadrants that cross is divided into, the vertical outward polyester belt that is surrounded by of twisted pair wire and cross, the vertical aluminium foil internal shield that is surrounded by outside polyester belt, aluminium foil internal shield inboard is provided with the percolation conductor that contacts with the aluminium foil internal shield, described aluminium foil internal shield is provided with inner sheath outward, inner sheath is provided with the outer shielding layer that is woven into by copper wire outward, the oversheath that the outer shielding layer peripheral hardware has the Halogen material to make.
When the present invention works, the two-layer shielding action of aluminium foil internal shield and outer shielding layer is arranged, its shield effectiveness is better; But percolation conductor ground connection can guarantee to greatest extent that external electromagnetic field can not produce electromagnetic interference to the signal transmission in the twisted pair wire, and simultaneously, the inner electromagnetic signal that produces can not disturbed other electronic equipments yet; Cross makes and is spaced from each other between each twisted pair wire and keeps certain distance that the mutual signal that can reduce like this between the twisted pair wire disturbs.Compared with prior art, the present invention has good anti-electromagnetic interference performance, simultaneously, also can not disturb other electronic equipments, and line loss is little, and it is little that signal transmits distortion, and its transmission performances parameter is better than the land with surpassing 5 class indexs (YD/T1019-2001); In addition, oversheath adopts low cigarette, Halogen, fire proofing to make, and has good fire-retardant, corrosion resistant effect.The present invention can be used for the naval vessel data communication, as the wiring of multimedia system, LAN (Local Area Network), data switching networks.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Wherein, 1 cross, 2 twisted pair wires, 3 polyester belts, 4 percolation conductors, 5 aluminium foil internal shields, 6 inner sheaths, 7 outer shielding layers, 8 oversheaths.
Embodiment
As figure, be low-smoke halogen-free flame-retardant digital communication cable for ship, comprise four pairs of twisted pair wires 2 separating mutually via cross 1, each twisted pair wire 2 correspondence is arranged in four quadrants that cross 1 is divided into, twisted pair wire 2 and the cross 1 outer vertical polyester belt 3 that is surrounded by, the vertical aluminium foil internal shield 5 that is surrounded by outside polyester belt 3, aluminium foil internal shield 5 inboards are provided with the percolation conductor 4 that contacts with the aluminium foil internal shield, the described aluminium foil internal shield 5 outer inner sheaths 6 that are provided with, the inner sheath 6 outer outer shielding layers 7 that are woven into by copper wire, the oversheath 8 that outer shielding layer 7 peripheral hardwares have the Halogen material to make of being provided with.
