Abstract
The utility model discloses a cable capable of shielding digital signals in railways, comprising a plurality of cable core conductors and an insulating layer, wherein the cable core conductors are divided into a plurality of conductor groups, and each group includes four cable core conductors; the cable core conductor is externally wrapped by an inner leather layer, a foaming layer, an outer leather layer, the insulating layer in sequence; the conductor group is externally wrapped by an isolating layer and a shielding layer in sequence; the outer sides of the plurality of conductor groups are wrapped by inner sheath layers, inner pad layers, armoring layers and outer sheath layers in sequence; the armoring layers are made of steel belts; and the inner sheath layers are made of aluminium. In the cable, the structure is novel, the cable strength is good, the shielding performance is good, the interference resistance is strong and the transmission efficiency is high.
Description
Technical field:
The utility model relates to the signal cable field, relates in particular to a kind of railway inner shield digital signal cable.
Background technology:
Cable is in order to transmit electricity (magnetic) energy, the wire product of information and the conversion of realization electromagnetic energy.Normally by the cable of several or at least two every group stranded similar ropes that form of several groups of leads, mutually insulated between every group of lead, and often be twisted into round a center, whole outside is surrounded by the cover layer of high-insulation.Electric wire mainly comprises bare wire, electromagnetic wire and electrical equipment and electrical insulated electric conductor, power cable, telecommunication cable and optical cable.
The utility model has carried out individually shielded to the transmission quad, be applicable to that railway signal automatically closes up, note axle, station coding, Microcomputer Detecting, dispatching concentration, dispatcher's supervision system, the electronic switching machine of high-power scheduling etc. are about control information transmission between signal control device and the equipment, detection information and electric energy can be used as the transmission channel of DMIS first floor system digital information and business telephone.
The utility model content:
Of the present utility model day provide a kind of railway inner shield digital signal cable, improved the cable near-end crosstalk attenuation, when having solved the railway signal information of transmission same frequency in the root cable, the interference defence problem between each transmission group.
Technical scheme of the present utility model is as follows:
A kind of railway inner shield digital signal cable, comprise many core conductors, insulating barrier, described core conductor is divided into a plurality of conductor groups, every group four, it is characterized in that: described core conductor is enclosed with endodermis outward successively, give out a contract for a project layer, exodermis, insulating barrier, described conductor group is enclosed with thermal insulation layer, screen outward successively, organizes the conductor group outside more and is enclosed with inner restrictive coating, inner cushion layer, armour, external sheath layer successively.
Described railway inner shield digital signal cable is characterized in that: described armor material adopts steel band, and the inner restrictive coating material adopts aluminium.
The utility model has the advantages that:
Novel structure of the present utility model, cable intensity is good, advantages of good shielding performance, antijamming capability is strong, the efficiency of transmission height.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
