Description

A kind of anti-interference anti-extrusion cable for digital communication
Technical field
The utility model relates to field of cables, particularly relates to a kind of anti-interference anti-extrusion cable for digital communication.
Background technology
At present, along with the development of science and technology, the communications field is all at rapid advances, and in the field of communications, telecommunication cable is as the medium of transmission of signal, its consumption is also increase gradually, telecommunication cable normally has several or several groups of wires often to organize the cable of at least two stranded similar ropes, often organize mutually insulated between wire, and be often twisted into around a center, whole outside is surrounded by the cover layer of high-insulation, the kind of cable has a lot, the environment for use that can be applied in fields different in a lot of field is different, therefore different requirements is also had to cable, but existing cable because of its structural design unreasonable, in the process of telecommunication cable signal transmission, be easy to the interference being subject to external electromagnetic signal, a lot of inconvenience is brought to people's life.
Utility model content
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of anti-interference anti-extrusion cable for digital communication.
The utility model is taked following technical scheme to realize: a kind of anti-interference anti-extrusion cable for digital communication, it comprises cable body, described cable body comprises conductor, insulating barrier, foil shielding layer and oversheath, and described cable body inside is provided with multiple conductor; Fixed by isolation mount between described conductor; Described isolation mount inside is provided with multiple aluminium alloy flexible pipe; Described conductor is outside equipped with a layer insulating; Between described insulating barrier and conductor, gap portion is provided with packed layer; One deck foil shielding layer is extruded outside described insulating barrier; The anti-interference layer of one deck is extruded outside described foil shielding layer; One deck oversheath is extruded outside described anti-interference layer.
The anti-interference anti-extrusion cable for digital communication of above-mentioned one, described conductor adopts real core copper core or multiply to press copper core and makes, and its cross sectional shape is circular or sector structure.
The anti-interference anti-extrusion cable for digital communication of above-mentioned one, described isolation mount is hollow-core construction.
The anti-interference anti-extrusion cable for digital communication of above-mentioned one, the packed layer arranged between described insulating barrier and conductor is glass cord.
The anti-interference anti-extrusion cable for digital communication of above-mentioned one, described insulating barrier adopts ethylene-propylene rubber to make.
The anti-interference anti-extrusion cable for digital communication of above-mentioned one, described oversheath is that semiconductive plastics are made.
The utility model has following beneficial effect in sum: the utility model cable has the advantages such as reasonable in design, strong interference immunity and long service life, described foil shielding layer enhances the ability of cable opposing outside electromagnetic interference, can control again simultaneously itself electromagenetic wave radiation, do not disturb the normal work of around other equipment and network, thus be applicable to more occasion.
Accompanying drawing explanation
Fig. 1 is the utility model cross-sectional structure schematic diagram;
Wherein: 1, cable body; 2, conductor; 3, isolation mount; 4, packed layer; 5, aluminium alloy flexible pipe; 6, insulating barrier; 7, foil shielding layer; 8, anti-interference layer; 9, oversheath.
Embodiment
As shown in Figure 1, a kind of anti-interference anti-extrusion cable for digital communication, it comprises cable body 1, and described cable body 1 comprises conductor 2, insulating barrier 6, foil shielding layer 7 and oversheath 9, and described cable body 1 inside is provided with multiple conductor 2; Fixed by isolation mount 3 between described conductor 2; Described isolation mount 3 inside is provided with multiple aluminium alloy flexible pipe 5; Described conductor 2 is outside equipped with a layer insulating 6; Between described insulating barrier 6 and conductor 2, gap portion is provided with packed layer 4; One deck foil shielding layer 7 is extruded outside described insulating barrier 6; The anti-interference layer 8 of one deck is extruded outside described foil shielding layer 7; One deck oversheath 9 is extruded outside described anti-interference layer 8.
Described conductor 2 adopts real core copper core or multiply to press copper core and makes, and its cross sectional shape is circular or sector structure, not only substantially increases the operating efficiency of cable, also makes its work more stable; The outer isolation mount 3 arranged of described conductor 2 not only can support various conductor 2, more importantly shields conductor 2, prevents from mutually transmitting interfere information between conductor 2, improve communication quality; Described aluminium alloy flexible pipe 5 improves the tensile resistance of cable, can not rupture easily; Described packed layer 4 material is glass cord, cable can not only being kept because producing deformation by external force, and externally can not can to pass to heat, the transmittability of cable being increased greatly, improves the operating efficiency of cable; Described insulating barrier 6 adopts ethylene-propylene rubber material to make, and can improve the insulation property of cable body 1, makes its work more stable; Described foil shielding layer 7 enhances the ability of cable opposing outside electromagnetic interference, can control again the electromagenetic wave radiation of itself simultaneously, does not disturb the normal work of around other equipment and network, thus is applicable to more occasion; Described anti-interference layer 8 effectively prevents external electromagnetic signal to the interference of cable, improves the job stability of cable; Described oversheath 9 is made for semiconductive plastics, improves the interference free performance of foil shielding layer 7, in use, not by the interference of other extraneous factors, thus ensures the stable of Signal transmissions.
The above is the utility model embodiment, therefore all equivalences done according to structure, feature and the principle described in the utility model application range change or modify, and are included in the utility model patent claim.
