Abstract
The invention relates to a safe anti-explosion computer input cable sequentially comprising four sets of split-screen cores, a cabled tape, an inner protective sleeve, a main screen and an outer protective sleeve, wherein each split-screen core comprises a conductor, an insulator, pair-twisted polyester tapes and pair-twisted split screens. Because the insulators are made from polyethylene and the protective sleeves are made from halogen-free polyvinyl chloride, the flame resistance, the high-temperature performance and the bending and flexible resistance of a product are greatly improved, and the safe anti-explosion computer input cable better solves the problems of measuring in special environment and using computer equipment on the occasions that the cable of the computer equipment has high flexibility; due to the adoption of the woven split screens (pair-twisted) and the woven main screen, the safe anti-explosion computer input cable has the advantages of flexible resistance on high-temperature occasions and favorable anti-electric and magnetic field interference performance, and in particular has outstanding anti-interference performance among cores; and on the occasions with low frequencies, high frequencies, ultra-high frequencies, variable frequencies and the like, the safe anti-explosion computer input cable still has precise anti-interference performance and has high temperature resistance and flame resistance because the flame resistance is also increased.
Description
Technical field the present invention relates to the computer input cable field, the concrete safe anti-explosion computer input cable that relates to.
Background technology is present, and existing computer cable does not have explosion-proof and performance flame-retarding, and the security reliability of cable is low under fire hazard environment, is not suitable for use in densely populated and higher to device security reliability requirement place.
Summary of the invention is in order to overcome above-mentioned deficiency, the dynamo-electric cable of measurements and calculations that main purpose of the present invention aims to provide a kind of anti-high and low temperature occasion and bending resistance requirement height, interference free performance height, security requirement height, explosion-proof occasion are used.
The technical solution adopted in the present invention is: safe anti-explosion computer input cable is followed successively by four components screen core, stranding band, inner sheath from the inside to the outside, always shielding, oversheath constitute; The split screen core is by being made up of conductor, insulator, twisted pair polyester band, pair twist split screen; Restrictive coating is to adopt fire proofing PVC to make, and can effectively solve the explosion-proof low cigarette of computer cable, the characteristic of low halogen; The woven structure mode is adopted in shielding, has effectively avoided the drawback of computer cable softness difference, and its technical performance can make bending radius dwindle on jamproof basis, becomes soft more.
The insulator of computer input cable of the present invention is to adopt PE, sheath to adopt Halogen PVC material, improve anti-fire-retardant, the high-temperature behavior of product and the anti-bending and the softness characteristics of product greatly, preferably resolved the service condition of the high occasion of the cable of measurements and calculations machine equipment under the particular surroundings and bendability; Adopt Weaving type to divide shielding (pair twist) and Weaving type always to shield, both solved the resistance to bend(ing) of high temperature occasion, have good anti-electric field, magnetic interference performance again, prevent that especially the interference free performance between core and the core is especially outstanding; Under occasions such as low frequency, high frequency, hyperfrequency and frequency conversion, still have accurate interference free performance, but also increased fire resistance, it is high temperature resistant fire-retardant again making cable.
The present invention has advantageous characteristic such as not prolonging combustion, acid and alkali-resistance profit, the construction of cable aims at the intrinsic safe explosion-proof circuit design, not only is used for crane span structure and lays, and can be used for that cable trough lays and directly buried installation, minimum ambient temperature: pvc sheath: fixedly lay-40 ℃, on-fixed lays-15 ℃.
Cable lay environment and operating temperature range is-60～90 ℃.
Its project organization of the present invention is scientific and reasonable, has both improved the safe class of cable, can guarantee that again the flexibility of cable reaches requirement of client, and is almost nil to the damage type of cable, and has characteristics such as with low cost, handling safety, use be very convenient.
Description of drawings
Fig. 1 is a simplified schematic diagram of the present invention;
Fig. 2 is a structural representation sketch of the present invention;
Embodiment
Be followed successively by four components screens core 1, stranding band 2, inner sheath 3 from the inside to the outside at Fig. 1, safe anti-explosion computer input cable shown in Figure 2, always shield 4, oversheath 5 constitutes; Split screen core 1 is made up of conductor 6, insulator 7, twisted pair polyester band 8, pair twist split screen 9; Restrictive coating the 3, the 5th adopts fire proofing PVC to make, and can effectively solve the explosion-proof low cigarette of computer cable, the characteristic of low halogen; The woven structure mode is adopted in shielding 4,9, has effectively avoided the drawback of computer cable softness difference, and its technical performance can make bending radius dwindle on jamproof basis, becomes soft more.
The insulator 7 of computer input cable of the present invention is to adopt PE, sheath 3,5 to adopt Halogen PVC material, improve anti-fire-retardant, the high-temperature behavior of product and the anti-bending and the softness characteristics of product greatly, preferably resolved the service condition of the high occasion of the cable of measurements and calculations machine equipment under the particular surroundings and bendability; Adopt Weaving type to divide shielding (pair twist) 9 and the total shielding 4 of Weaving type, both solved the resistance to bend(ing) of high temperature occasion, have good anti-electric field, magnetic interference performance again, prevent that especially the interference free performance between core and the core is especially outstanding; Under occasions such as low frequency, high frequency, hyperfrequency and frequency conversion, still have accurate interference free performance, but also increased fire resistance, it is high temperature resistant fire-retardant again making cable.
