Abstract

The utility model discloses a computer cable for an intrinsically safe circuit, comprising five annularly-arrayed twisted-pair conductor groups, wherein the twisted-pair conductor group comprises two conductors wrapped with insulating layers; the two conductors wrapped with the insulating layers are twisted in pairs and then are sequentially wrapped with an inner lapping layer, a lining layer I and an outer lapping layer at the outer sides from inside to outside; a filler with a circular section is filled in a gap among the five annularly-arrayed twisted-pair conductor groups; a hollow filling tube with a triangular section is arranged in a gap between the filler and the two adjacent twisted-pair conductor groups; the five twisted conductor groups are sequentially wrapped with a lapping layer, a lining layer II, a shielding layer and an outer protecting layer at the outer sides of form inside to outside; a plurality of tensile steel wires are arranged on the outer protecting layer; and a plurality of drainage wires are arranged at the inner side of the shielding layer. According to the utility model, via the added tensile steel wires and filling tube, the tensile performance and the firmness of the cable are enhanced in the case that the weight of the cable is not increased as much as possible; via the independent shielding layer, the shielding characteristic of the cable is enhanced; and via the drainage wires, the safety of the cable is enhanced.

Description

The intrinsically safe circuit computer cable
Technical field
The utility model relates generally to technical field, relates in particular to a kind of intrinsically safe circuit computer cable.
Background technology
Wires and cables industry is the second largest industry that China is only second to automobile industry, and product variety satisfies rate and domestic market occupation rate all above 90%.Worldwide, the Chinese electric wire gross output value has surpassed the U.S., becomes in the world first electric wire producing country.Be accompanied by Chinese wires and cables industry high speed development, creation of new enterprise quantity constantly rises, and industry overall technology level is largely increased.China's economic growth continuously and healthily, for cable products provides the huge market space, the temptation that Chinese market is strong is so that the world all focuses on Chinese market to sight, reforming and opening up to the outside world short decades, the formed huge production capacity of Chinese cable manufacturing industry allows the world regard with special esteem.Along with the continuous expansion of the industry sizes such as China Power industry, data communication industry, urban track traffic industry, car industry and shipbuilding, also will increase rapidly the demand of electric wire, following electric wire already also has huge development potentiality.
The application of electronic computer, instrument and meter is day by day universal, and people's awareness of safety constantly strengthens, and performance and the environmental requirement of the cable supporting with it also improved constantly.Existing computer and instrument are high temperature resistant not high with fire resistance with cable, and the security reliability of cable is low under fire condition, and shielding properties and interference free performance are not high, are not suitable for use in densely populated and higher to device security reliability requirement place.
Therefore, be badly in need of a kind of high temperature resistant, anti-flammability, shielding, intrinsically safe circuit computer cable that anti-interference is good, safe.
The utility model content
The utility model purpose is exactly in order to remedy the defective of prior art, and a kind of anti-flammability, intrinsically safe circuit computer cable that anti-interference is good are provided.
The utility model is achieved through the following technical solutions:
The intrinsically safe circuit computer cable, include five pair twist conductor groups, described five pair twist conductor group circular array, it is characterized in that: described pair twist conductor group includes two conductors that are enclosed with insulating barrier, two conductor pair twists that are enclosed with insulating barrier, the conductor outside behind the pair twist is enclosed with interior lapping layer from inside to outside successively, inner covering one, outer lapping layer, consist of pair twist conductor group, gap in the middle of the pair twist conductor group of described five circular array is filled with a cross section and is circular filler, it is leg-of-mutton filling pipe that gap between filler and adjacent two the pair twist conductor groups is provided with hollow cross section, described five pair twist conductor groups are carried out stranded, five conductor group outsides after stranded are enclosed with lapping layer from inside to outside successively, inner covering two, screen, outer jacket, described outer jacket is provided with many tension steel wires, and the inboard of screen is provided with several drainage threads.
Described screen adopts proof copper-wire braided to form.
What described conductor adopted is bare copper wire.
The utility model has the advantages that:
The utility model is safe and reliable, strong interference immunity, high temperature resistant, the tension steel wire of setting up and filling pipe, in the situation that not increasing cable weight has strengthened the pull resistance of cable of the present utility model, fastness as far as possible, individually shielded layer has strengthened its shielding character, and drainage thread has been strengthened its fail safe.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the intrinsically safe circuit computer cable, include five pair twist conductor groups, five pair twist conductor group circular array, pair twist conductor group includes two conductors 1 that are enclosed with insulating barrier 2, two conductor 2 pair twists that are enclosed with insulating barrier 1, conductor 1 outside behind the pair twist is enclosed with interior lapping layer 3 from inside to outside successively, inner covering 1, outer lapping layer 5, consist of pair twist conductor group, gap in the middle of the pair twist conductor group of five circular array is filled with a cross section and is circular filler 6, it is leg-of-mutton filling pipe 7 that gap between filler 6 and adjacent two the pair twist conductor groups is provided with hollow cross section, five pair twist conductor groups are carried out stranded, five conductor group outsides after stranded are enclosed with lapping layer 8 from inside to outside successively, inner covering 29, screen 10, outer jacket 11, outer jacket 11 is provided with many tension steel wires 13, and the inboard of screen 10 is provided with several drainage threads 12.
Screen 10 adopts proof copper-wire braided to form.
What conductor 1 adopted is bare copper wire.
