Background technology

Traditional data cable is widely used in indoor horizontal wiring, is increasingly popularized with the intellectuality of terminal applies, network To transmission bandwidth and transmission rate request also more and more higher in, data cable must be more applied in outdoor and pipeline, The function such as sting for waterproof, uvioresistant, electromagnetism interference and protection against rodents (toy) and improve requirement.Traditional indoor shielding type number The pattern of bag is typically indulged using the structure of one layer of aluminum foil shielded, aluminium foil generally use according to cable, in cable bend in bending place very Easily because aluminium foil opening causes impedance spike and loop resistance increase (decay increases).In outdoor utility, it is easier to because of ring Border badly causes electrical property drastically to decline.Therefore, how the high-end data cable of shield type is applied to outdoor, it is ensured that data cable Communication quality do not decline and reach waterproof, the specific function such as mouse bite preventing, while cost increase is few on the original basis, more extensively Application is the problem that urgency is to be tackled key problems instantly generally.Lack unified standard for outdoor utility in industry at present, meet data On the premise of the performance and particular/special requirement of cable, the utility model solves well had both retained the anti-electromagnetism of shield type house data cable Interference performance is strong, good flame resistance, the advantages of transmission bandwidth is high, adds waterproof, uvioresistant, protection against rodents (toy) again and stings, the longevity The advantages that long is ordered, has the characteristics that innovative, advanced, production efficiency is high.

The content of the invention

The utility model provides a kind of shield type armouring sheath data cable, using duplex sheath technology, overcomes original biography The drawbacks of system shield type sheath is only used for interior.

To reach above-mentioned purpose, the technical solution of the utility model is as follows：

A kind of shield type armouring sheath data cable, it includes cable core, and polyester belt is coated with outside the cable core, described poly- Aluminium foil is coated with outside ester band, inner sheath is coated with outside the aluminium foil, steel band, the steel band are coated with outside the inner sheath Outside is coated with oversheath；

The steel band includes：Steel band basic unit, the first gauze layer of steel band basic unit one side is arranged on, be arranged on described Second gauze layer of the first gauze layer one side, drying layer and mould proof is provided between first gauze layer and the second gauze layer Layer.

In a preferred embodiment of the present utility model, further comprise, the inner sheath is PVC sheath.

In a preferred embodiment of the present utility model, further comprise, the oversheath is anti-UV sheaths.

In a preferred embodiment of the present utility model, further comprise, in addition to drain wire, the drain wire are set In the aluminium foil, the drain wire is axially arranged along cable.

In a preferred embodiment of the present utility model, further comprise, the cable core includes some conductor lines pair, institute Conductor lines are stated to being coated with insulating barrier including two conductors, the outside of every conductor.

The beneficial effects of the utility model are:

1. the utility model replaces former one layer of PVC sheath using the anti-UV sheaths of steel-tape armouring, meet electromagnetism interference and Electrical property simultaneously, adds the functions such as waterproof, uvioresistant, mouse bite preventing.

2. the utility model uses steel-tape armouring sheath, the protective effect to core is strengthened, adds the anti-of data cable Electromagnetic interference capability, though together with other communication cable layings, do not interfere with yet data cable frequency transfer characteristic and Transmission bandwidth.

3. the utility model uses steel-tape armouring sheath, tension and crushing resistance of the product in pipeline laying are improved, is made It is more convenient to obtain mounting and installation, while adds the life-span of data cable outdoor application.

4. cable core of the present utility model directly uses indoor shielding data cable to utilize existing ripe technique as cable core Technology, simply increase steel-tape armouring in oversheath link, production technology is easily realized, the efficiency high of production.

5. steel band of the present utility model uses compound steel band of model, while there is armouring function, also with humidity resistance and Fungicidal properties, it can further lift the waterproof and dampproof performance of cable.

Brief description of the drawings
