Abstract
The utility model relates to a high temperature resistant anti-interference computer cable and solves the technical problem that the interference rejection of the existing cable is not strong. The high temperature resistant anti-interference computer cable provided by the utility model is characterized in that a conductor is wrapped with an insulating layer to form core wires, every two core wires are twisted together so as to form a core wire group; a pair of twisting groups is wrapped with a twisting group taped covering and the twisting group taped covering is wrapped with a shielding layer and a fire-resistant layer sequentially, thus forming a conductive core wire group; and at least two pairs of conductive core wire groups are wrapped with a high-resistance strip winding covering, a total shielding layer, an oxygen exclusion layer, a mica tape fire-resistant layer and an outer protection layers in sequence, thus obtaining the whole high temperature resistant anti-interference computer cable. The high temperature resistant anti-interference computer cable provided by the utility model is broadly applied to detection/control-purposed computer system or an automated device in departments such as metallurgy, generate electricity and chemical industry.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of high temperature resistant anti-interference computer cable.
Background technology
Computer cable different occasions use can both the normal transmission electric energy and signal stabilization be very important.If cable uses at special occasions or is subject to strong electromagnetic, and the cable antijamming capability is not strong, easily cause signal transmission disorderly, make equipment produce misoperation, even cause casualties and the heavy damage of property.
The utility model content
The utility model will solve the not strong technical problem of existing cable antijamming capability; And provide high temperature resistant anti-interference computer cable.
The utility model is realized by the following technical solutions: high temperature resistant anti-interference computer cable comprises conductor, insulating barrier, pair twist group lapping layer, screen, flame retardant coating, high stopband lapping layer, total screen, oxygen barrier layer, mica tape flame retardant coating and outer jacket, it is characterized in that conductor is surrounded by insulating barrier, consist of heart yearn; Per two heart yearns strand consists of the heart yearn group together, and every pair of heart yearn group is surrounded by pair twist group lapping layer outward, and strand group lapping layer is surrounded by screen and flame retardant coating outward successively, consists of the conductive core line group; At least two pairs of conductive core line groups are surrounded by high stopband lapping layer, total screen, oxygen barrier layer, mica tape flame retardant coating and outer jacket outward successively, consist of whole high temperature resistant anti-interference computer cable.
Compared with prior art, the beneficial effects of the utility model are: the utlity model has good fire-retardant, high temperature resistant, anticorrosion, anti-interference, the performance such as transmission rate is fast, can be adapted to different occasions, be specially adapted to the signal transmission of the computer automation system in longevity of service, high-temperature operation district.The utility model can be widely used in detection and control computer system or the automation equipment of the departments such as metallurgy, generating, chemical industry.
The utility model is described in further detail below in conjunction with drawings and embodiments.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment one: present embodiment is described in conjunction with Fig. 1, the utility model is high temperature resistant anti-interference computer cable, it comprises conductor 1, insulating barrier 2, pair twist group lapping layer 3, screen 4, flame retardant coating 5, high stopband lapping layer 6, total screen 7, oxygen barrier layer 8, mica tape flame retardant coating 9 and outer jacket 10, it is characterized in that conductor 1 is surrounded by insulating barrier 2, consist of heart yearn; Per two heart yearns strand consists of the heart yearn group together, and every pair of heart yearn group is surrounded by pair twist group lapping layer 3 outward, and strand group lapping layer 3 outer screen 4 and the flame retardant coatings 5 of being surrounded by successively consist of the conductive core line group; Three pairs of conductive core line groups are surrounded by high stopband lapping layer 6, total screen 7, oxygen barrier layer 8, mica tape flame retardant coating 9 and outer jacket 10 outward successively, consist of whole high temperature resistant anti-interference computer cable.
Embodiment two: in conjunction with Fig. 1 present embodiment is described, what present embodiment and embodiment one were different is: conductor 1 is tinned wird.Other composition is identical with embodiment one with annexation.
