Description
Technical field
The utility model relates to field of cables, particularly relates to a kind of insulation shielding cable for digital communication.
Background technology
At present, along with the fast development of the communication technology, as the communications cable of information transmitting medium, it is the staple product that those skilled in the art are devoted to research and develop energetically, and the thing followed is the production of the communications cable and consumption is also increasing year by year, but increasing of electronic equipment, bring a lot of electromagnetic wave to disturb cable, and the needs that general telecommunication cable can not meet people because its structural design is unreasonable, play the effect of shielding external electromagnetic ripple, bring a lot of inconvenience to the signal transmission of cable.
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 insulation shielding cable for digital communication.
The utility model is taked following technical scheme to realize: a kind of insulation shielding cable for digital communication, and it comprises cable body, and described cable body comprises conductor, insulating barrier, screen and oversheath, and described cable body inside is provided with many conductors; Outside described conductor, layer protective layer is set; Described conductor and protective layer form cable core jointly; Described cable core is outside equipped with a layer insulating; Described cable body inside is provided with many drain wires; Described cable core, between insulating barrier and drain wire, gap portion is provided with packed layer; One deck screen is extruded outside described insulating barrier; One deck high-temperature-resistant layer is extruded outside described screen; One deck oversheath is extruded outside described high-temperature-resistant layer.
Above-mentioned a kind of insulation shielding cable for digital communication, described conductor is multiply naked copper or tin plated materials is stranded forms.
Above-mentioned a kind of insulation shielding cable for digital communication, described screen adopts copper strips to make.
Above-mentioned a kind of insulation shielding cable for digital communication, described oversheath is made up of polythene material.
Above-mentioned a kind of insulation shielding cable for digital communication, described insulating barrier is woven by tin annealed copper wire to form, and the tin annealed copper wire count of described insulating barrier is no less than 90%.
Owing to have employed such scheme, compared with the prior art, the utility model has the advantages such as the good and long service life of reasonable in design, shield effectiveness, described screen adopts copper strips to make, cable is made to have superior interference free performance, in use, not by the interference of other outer signals, effectively ensure that the stability of Signal transmissions.
Accompanying drawing explanation
Fig. 1 is the utility model cross-sectional structure schematic diagram;
Wherein: 1, cable body; 2, conductor; 3, protective layer; 4, packed layer; 5, drain wire; 6, insulating barrier; 7, screen; 8, high-temperature-resistant layer; 9, oversheath.
Embodiment
As shown in Figure 1, a kind of insulation shielding cable for digital communication, it comprises cable body 1, and described cable body 1 comprises conductor 2, insulating barrier 6, screen 7 and oversheath 9, and described cable body 1 inside is provided with many conductors 2; Outside described conductor 2, layer protective layer 3 is set; Described conductor 1 and protective layer 3 form cable core jointly; Described cable core is outside equipped with a layer insulating 6; Described cable body 1 inside is provided with many drain wires 5; Described cable core, between insulating barrier 6 and drain wire 5, gap portion is provided with packed layer 4; One deck screen 7 is extruded outside described insulating barrier 6; One deck high-temperature-resistant layer 8 is extruded outside described screen 7; One deck oversheath 9 is extruded outside described high-temperature-resistant layer 8.
Described conductor 2 is for multiply naked copper or tin plated materials is stranded forms, and conductor 2 signal transmission not only can be made more stable, and be not easy to fracture, also be convenient to the maintenance of later stage workman; The outer protective layer 3 arranged of described conductor 2, the advantages such as it has, and intensity is high, corrosion-resistant, ageing-resistant, good insulating and good heat resistance, effectively protect inside cable, there will not be the situation of scratch cable, cable is operationally more stable; Described packed layer 4 can improve the structural compactness of cable body 1 inside, conductor 2 can not be offset, improve service behaviour; The drain wire 5 that described cable body 1 inside is arranged can reach the requirement of protective earthing and bonding, effectively can solve the problem of cross-talk between line pair, ensure that signal effectively transmits; Described insulating barrier 6 is woven by tin annealed copper wire to form, and the tin annealed copper wire count of described insulating barrier 6 is no less than 90%, can effectively raise the insulation effect of cable body 1, makes its work more stable; Described screen 7 adopts copper strips to make, and makes cable have superior interference free performance, in use, not by the interference of other outer signals, effectively ensure that the stability of Signal transmissions; Described high-temperature-resistant layer 8 effectively raises the resistance to elevated temperatures of cable body 1, prevents cable damaged at high operating temperatures, extends the useful life of cable; Described oversheath 9 adopts polythene material to make; described polythene material is through special processing technique; change polyethylene linear molecular structure into vertical network molecular structure; substantially increase the electric property of product, physical property and mechanical performance; resistance to elevated temperatures is strong, flammable poor, even if catch fire also can not produce pernicious gas; cable would not discharge when burning the gas jeopardizing human body, protects the life and health of people.
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.
