Abstract
The utility model discloses a high temperature resistant fireproof cable for electronic computer, which comprises a conductor, an insulation layer, a general lapping layer, a general shielding layer and a core wire composed by coating an insulation layer on a sheath layer; each two core wires are twisted together to form a pair of core wire group; a pair twisted group lapping layer and a pair twisted sub screen layer is coated successively on each pair of core wire group to form a cable core group; a fireproof general lapping layer, a general shielding layer, an extra outer lapping layer and an sheath layer are coated successively on the cable core group. The utility model has excellent flame-retardant, high temperature resistant and interference resistant performance, and high transmission speed; is adapted to different occasions, especially adapted to the computer system with long working time, at high temperature or open fire operation area, automatic detection system connected with multiple pairs of shielding cables for connection.
Description
Technical field:
The utility model relates to a kind of cable, specifically a kind of fire resistant electronic computer cable.
Background technology:
The applicability of cable and integrality, for use in different occasions can both the normal transmission electric energy and signal stabilization be very important, if cable uses at special occasions or is subjected to strong electromagnetic, and the cable antijamming capability is not strong, easily cause the transmission signals disorder, make equipment produce misoperation, even cause casualties and the heavy damage of property.
There is weak point in the computer cable that uses aspect high temperature resistant at present, insulating barrier, lapping layer, the employed material of sheath are good inadequately at the fire resistant aspect of performance, particularly lack flame retardant coating, therefore this cable can't normally use under hot environment.
The purpose of this utility model is at the problems referred to above, designs a kind ofly under adverse circumstances, especially can guarantee the normal fire resistant electronic computer cable that uses under hot conditions.
The utility model content:
For overcoming the defective of prior art, it is a kind of in adverse circumstances that the purpose of this utility model is to provide, and especially can guarantee normal a kind of fire-retardant, high temperature resistant, anti-interference, the high temperature resistant SHIELDING CALCULATION machine cable that transmission rate is fast that uses under hot conditions.
The utility model technical solution problem adopts following technical scheme:
Fire resistant electronic computer cable, comprise that conductor, insulating barrier, total lapping layer, total screen and restrictive coating conductor are surrounded by insulating barrier outward and constitute heart yearn, per two heart yearns strand constitutes a pair of heart yearn group together, every pair of heart yearn group is surrounded by pair twist group lapping layer outward, pair twist group lapping layer is surrounded by pair twist component screen outward and constitutes the cable core group, and the cable core group is surrounded by fire-resistant total lapping layer outward, and total lapping layer is total screen outward, total screen adds around outer lapping layer, and outermost layer is a restrictive coating.
Described outer lapping layer is a glass fiber tape.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
The utlity model has good fire-retardant, high temperature resistant, anti-interference, performance such as transmission rate is fast, can be applicable to different occasions, the connection of computer system, automated detection system that is specially adapted to long, high temperature of operating time or the work with torches district arranged with many to shielded type cable; Fluoroplastic insulation and sheath are set in the cable, excellent, the good stability of insulation property, high temperature resistant, corrosion resistant performance is strong; Adopt sub-shield that stranding is added copper strips and always shield, multipoint earthing, anti-strong electromagnetic ability are strong, and the signal transmission accurately.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Number in the figure: 1 is conductor, and 2 is insulating barrier, and 3 is pair twist group lapping layer, and 4 is pair twist component screen, and 5 is total lapping layer, and 6 is total screen, and 7 is outer lapping layer, and 8 is restrictive coating.
Below pass through embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
Embodiment,
Non-limiting examples is as described below:
Embodiment: shown in Figure 1, in the present embodiment, conductor 1 adopts copper wire to make, insulating barrier 2 is made by fluoroplastics (F46), and pair twist group lapping layer 3 forms by the double-layer polyester band is wrapped, and pair twist component screen 4 is formed by the copper wire braiding, total lapping layer 5 is added by the single-layer polyester band that double-deck mica tape is wrapped to form, total screen 6 forms for the copper wire braiding, and adding glass fiber tape is outer lapping layer 7, and outermost layer 8 is fluoroplastics (F46) restrictive coatings.During making, the conductor 1 outer insulating barrier 2 that is surrounded by constitutes heart yearn; Per two heart yearns strand constitutes a pair of heart yearn group (the utility model be 2-48 to) together, and every pair of heart yearn group is surrounded by pair twist group lapping layer 3 outward, and pair twist group lapping layer is surrounded by pair twist component screen 4 outward, constitutes the conductive core line group; The conductive core line group is surrounded by fire-resistant total lapping layer 5 outward, and lapping layer is outward total screen 6, and total screen adds lapping layer 7 outside the conduct of layer of glass band, and outermost layer is a restrictive coating 8, constitutes whole cable.
Claims (2)
1, fire resistant electronic computer cable, it is characterized in that, comprise conductor (1), insulating barrier (2), total lapping layer (5), total screen (6) and restrictive coating (8), it is characterized in that, the outer insulating barrier (2) that is surrounded by of conductor (1) constitutes heart yearn, per two heart yearns strand constitutes a pair of heart yearn group together, every pair of heart yearn group is surrounded by pair twist group lapping layer (3) outward, pair twist group lapping layer is surrounded by pair twist component screen (4) outward and constitutes the cable core group, the cable core group is surrounded by fire-resistant total lapping layer (5) outward, total lapping layer is total screen (6) outward, and total screen adds around outer lapping layer (7), and outermost layer is restrictive coating (8).
