Description
Technical field
The utility model relates to communications cable technical field, particularly relates to a kind of twisted-pair cable of advantages of good shielding performance.
Background technology
Twisted-pair feeder is a kind of general-purpose distribution being intertwined mutually according to certain specification by the wire of two mutually insulateds and making, and belongs to what communication network transmission medium.Twisted-pair feeder is divided into Shielded Twisted Pair (Shielded Twisted Pair, STP) and unshielded twisted pair (Unshielded Twisted Pair, UTP).Wherein, Shielded Twisted Pair has a metal level to cover layer between twisted-pair feeder and outer layer insulation big envelope.Screen can reduce radiation, prevents information to be ravesdropping, and also can stop entering of external electromagnetic interference, makes Shielded Twisted Pair have higher transmission rate than similar unshielded twisted pair.But existing Shielded Twisted Pair cable is at shielding interference free performance and need to improve on fire protection flame retarding.
Utility model content
For the present situation of above-mentioned prior art, it is good that technical problem to be solved in the utility model is to provide a kind of shielded signal performance, and have the Shielded Twisted Pair cable of the well combustion-supporting performance of fire prevention.
The utility model solves the problems of the technologies described above adopted technical scheme: Shielded Twisted Pair cable, comprise sheath and be located at four pairs of twisted-pair feeders in sheath, described often pair of twisted-pair feeder is that the wire stranding of two mutually insulateds forms, the outside of described often pair of twisted-pair feeder is equipped with internal shield, outer shielding layer is established in the outside of described four pairs of twisted-pair feeders, is provided with flame resistant filler layer between described outer shielding layer and internal shield.
Further, in the middle of described four pairs of twisted-pair feeders, be provided with drain wire, avoid thunder and lightning to attack cable cable directly.
Further, described flame resistant filler layer is glass fibre packed layer, promotes the fire resistance of cable.
Further, described outer shielding layer is metal lapped shielding layer, Stability Analysis of Structures, and shielding properties is excellent.
Further, described internal shield is aluminium foil layer or copper foil layer.
Compared with prior art, the utility model has the advantage of: the utility model adopts and arrange internal shield outside often pair of twisted-pair feeder, outer shielding layer is set outside four pairs of twisted-pair feeders simultaneously, the shielding properties of cable entirety is got a promotion, has and well shield interference free performance, fully meet the requirement of modern communications industry, in addition, adopt and flame resistant filler layer is set between internal shield and outer shielding layer, make cable have good combustion-supporting performance, the utility model is reasonable in design, is applicable to large-scale promotion.
Accompanying drawing explanation
Fig. 1 is the structural representation of preferred embodiment of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based in the utility model being embodiment, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Shielded Twisted Pair cable, comprise sheath 1 and be located at four pairs of twisted-pair feeders 2 in sheath 1, the wire 21 that the often pair of twisted-pair feeder 2 comprises two mutually insulateds is stranded to be formed, internal shield 3 is equipped with in the outside of often pair of twisted-pair feeder 2, preferably, this internal shield 3 is aluminium foil layer or copper foil layer, outer shielding layer 6 is established in the outside of four pairs of twisted-pair feeders 2, preferably, this outer shielding layer 6 is metal lapped shielding layer, its shielding properties is excellent, flame resistant filler layer 4 is provided with between described outer shielding layer 6 and internal shield 3, described flame resistant filler layer 4 is glass fibre packed layer, promote the fire resistance of cable, drain wire 5 is provided with in the middle of described four pairs of twisted-pair feeders 2, thus avoid thunder and lightning to attack cable cable directly.
Compared with prior art, the utility model has the advantage of: the utility model adopts and arrange internal shield outside often pair of twisted-pair feeder, outer shielding layer is set outside four pairs of twisted-pair feeders simultaneously, the shielding properties of cable entirety is got a promotion, has and well shield interference free performance, fully meet the requirement of modern communications industry, in addition, adopt and flame resistant filler layer is set between internal shield and outer shielding layer, make cable have good combustion-supporting performance, the utility model is reasonable in design, is applicable to large-scale promotion.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, it will be understood by those of skill in the art that it still can be modified to the technical scheme described in foregoing embodiments, or wherein portion of techniques feature has been replaced on an equal basis; And these amendments or replacement, do not make corresponding.
