Abstract
The utility discloses a low smoke zero halogen flame-retardant digital communication cable for ship comprising four pair of twisted pair separated by cross. Every twisted pair is correspondingly disposed in four quadrants separated by the cross, polyester tape is wrapped longitudinally around twisted pair and cross, aluminum foil inner shielding layer is wrapped longitudinally around polyester tape, aluminum foil inner shielding layer is provided with a passing conductor contacting with and disposed inside of the aluminum foil inner shielding layer, and a outer sheath is disposed outside of outer shielding layer. The cable has two layer of shielding layer and good shielding effect; the passing conductor can earth, internally produced electromagnetic signal can not interfere other electronic equipment; the cross can reduces mutual signal interference between twisted pairs. The cable has good performance for resisting electromagnetic interference, small distortion for signal delivery, and can be used for data communication for ship.
Description
Technical field
The utility model 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.
The utility model content
The purpose of this utility model provides a kind of low-smoke halogen-free flame-retardant digital communication cable for ship, makes the antijamming capability of cable stronger, and simultaneously, can also avoiding to external world, electronic equipment produces interference.
The purpose of this utility model is achieved in that 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.
During the utility model work, 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 utlity model has good anti-electromagnetic interference performance, simultaneously, also can not disturb other electronic equipments, 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 utility model 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 the utility model structural representation.
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.
