Abstract

The utility model discloses a computer shielded cable. A cable core of the computer shielded cable is composed of a plurality of wire cores, first flame-retardant fillings are arranged among the wire cores, and a flame-retardant fire-resistant belting, a first water-resisting thin film layer, an anti-interference shielding layer and a low-smoke zero-halogen polyolefin sheathing compound are arranged outside the cable core in sequence. The structure of the wire cores comprise a wire pair, wherein the wire pair is stranded by two conductors, and flame-retardant fire-resistant mica tapes and low-smoke zero-halogen insulating layers are respectively arranged outside the two conductors. Second flame-retardant fillings are arranged among the wire pairs, and a fire-proof flame-retardant belting, a second water-resisting thin film layer and an interference resistance copper wire braided layer are sequentially arranged outside the wire pair to form the wire cores. The computer shielded cable has the safety characteristics of being flame-retardant, fire-resistant, low-smoke, zero-halogen, low- toxicity, and containing no harmful elements; after fire accidents, the computer shielded cable is non-flammable, has little smoke harm and the like. Simultaneously, signals can be prevented from mutual interference, intercross and confusion, and external interference is avoided.

Description

A kind of computer shield cable

Technical field

The utility model relates to a kind of cable, specifically is a kind of computer shield cable.

Background technology

[0003Along with popularizing of computer technology, computerized information is more and more frequent alternately, and transmission of Information and reception growth at double make computer cable obtain utilization widely.The phase mutual interference easily takes place in the transmission of Information signal, influences the accuracy and the sensitivity of information, causes occurring that people can't expect even inestimable consequence, and this just requires computer cable to have good shielding.And for the physical property of computer cable, can contain many harmful elements in the traditional cable material, when breaking out of fire, can discharge a large amount of smog and acid gas, this not only pollutes environment, also can produce injury to human body, also have when burning, some signals have little time to be accepted and are saved, and also can also have been brought unnecessary loss economically, so require computer cable also will have the flame-retardant characteristic.But existing computer cable can not get both aspect these two, has reduced the fail safe that computer cable uses.

The utility model content

The purpose of this utility model provides the computer shield cable of the low cigarette of a kind of many logarithms, Halogen, flame-retardant phase-splitting shielding.

A kind of computer shield cable, it comprises the cable core that is positioned at cable center, described cable core is made up of the several wire core, be provided with the first fire-retardant filler between the core, outside cable core, be provided with flame-retardant band, first block water thin layer, anti-interference lapped shielding layer and low-smoke halogen-free polyolefin protective cover material successively, the structure that it is characterized in that described core comprises that line is right, line is to being stranded the forming of conductor that is set gradually flame-retardant mica tape and low-smoke halogen-free flame-retardant isolating layer by two outsides, line between be provided with the second fire-retardant filler; Line externally sets gradually block water thin layer and anti-interference copper wire braid of fire protection flame retarding band and second and forms core

The utility model mainly has flame-retardant, low cigarette, Halogen low toxicity and does not contain harmful element, security features such as nonflammable and smog injury is little after breaking out of fire have anti-stop signal to disturb mutually simultaneously, intersect mutually, be not subjected to external interference, avoid obscuring of signal.The utility model material therefor is recyclable polyolefine material, and when breaking out of fire, cable is nonflammable, and can operate as normal a period of time, help the reception and the preservation of signal data, when burning, also do not have the generation of smog and harmful substance, help personnel's evacuation and fire extinguishing.Can not produce toxic gas, to personnel, equipment, instrument damage is minimum.

Description of drawings

Fig. 1 is the cross-sectional structure schematic diagram of a kind of embodiment of the utility model.

Embodiment

Further specify the utility model below in conjunction with drawings and Examples.

With reference to Fig. 1, a kind of anti-interference computer shield cable of the present utility model, its core is that line is right, and line is to being conductor 1 stranded the forming that is set gradually flame-retardant mica tape 2 and low-smoke halogen-free flame-retardant isolating layer 3 by two outsides, line between be provided with the second fire-retardant filler 4; Line externally sets gradually fire protection flame retarding band 5 and second thin layer 6 and the anti-interference copper wire braid 7 that block water and forms cores.Cable core is made up of the several wire core, is provided with the first fire-retardant filler 8 between the core, is provided with flame-retardant band 9, first block water thin layer 10, anti-interference lapped shielding layer 11 and low-smoke halogen-free polyolefin protective cover material 12 outside cable core successively.

The utility model provides the thinking and the implementation method of the dynamo-electric cable of a kind of anti-interference SHIELDING CALCULATION; it more than is the concrete practical examples of this example; the protection range novel to this example do not constitute any limitation; except that above-mentioned example; the novel execution mode that other can also be arranged of this example; all employings are equal to the technical scheme of replacement or equivalent transformation formation, will drop within the novel protection range of this example.
