Heat-resistant ultraviolet truck data cable

Technical field

The utility model relates to truck data field of cables, is specifically related to a kind of heat-resistant ultraviolet truck data cable.

Background technology

Along with the high speed development of data communication and information technology, the fast development of network technology and improving constantly of computing power, the requirement of people to comprehensive wiring system performance is also more and more higher.From traditional audio frequency copper core pair twist local cable to today up to gigabit than local area network technology, along with network rate improves day by day, mean the raising of operating frequency, more easily produce electromagnetic radiation and capacitive coupling.Simultaneously, new electromagnetic interference source can be constantly had to produce in surrounding environment, the radiation of the higher generation of network operating frequencies is also more serious, and the equilibrium response of UTP non-masked data cable has been not enough to offset the electromagnetic radiation of express network itself and the electromagnetic interference (only can meet Electro Magnetic Compatibility during 30 ~ 40MHz transfer of data) in the external world, adopt shield technology then can effectively prevent outside electromagnetic interference from entering cable inside (skin effect of metal screen layer), stop cable internal signal to external radiation (reflection effect of metal screen layer) simultaneously.Because the competition of each manufacturer is also more and more fierce, how to ensure under the prerequisite that manufacturing cost is minimum, improve the first-time qualification rate of product, farthest to improve and the performance index improving product seem particularly important.

Utility model content

The utility model object is to provide a kind of heat-resistant ultraviolet truck data cable, this heat-resistant ultraviolet truck data cable had both improve digital communication cable fire resistance, also improve digital communication cable insulation property, and the raised line of insulating jacket layer embeds in the groove of described fire-retardant sheath, avoid the defect of the easy layering of connecting sewing, improve adhesive strength, reduce the difficulty of cable working technology, improve properties of product reliability.

For achieving the above object, the technical solution adopted in the utility model is: a kind of heat-resistant ultraviolet truck data cable, comprising: eight round metal conductors, all outer insulating layer coating of this round metal conductor; In described eight round metal conductors, two round metal conductor composition first strands are to line, and two round metal conductor composition second strands are to line; Two round metal conductor composition the 3rd strands are to line; Two round metal conductor composition the 4th strands are to line;

Described round metal conductor comprises the first aluminum-alloy wire that is positioned at center, and 6 second aluminum-alloy wires are stranded in the first aluminum-alloy wire surrounding formation outer conducting layer;

One fire-retardant sheath is coated on described first strand and twists line outer surface line and the 4th line, the 3rd strand line, the second strand, and described fire-retardant sheath outer surface circumferentially has several grooves;

One insulating jacket layer inner surface circumferentially has several raised lines, and an insulating jacket layer is coated on described fire-retardant sheath outer surface, and the raised line of insulating jacket layer embeds in the groove of described fire-retardant sheath.

The technical scheme of the further improvement in technique scheme is as follows:

In such scheme, in described insulating jacket layer, the number of raised line is 6 ~ 10, and the number of described fire-retardant sheath further groove is 6 ~ 10.

Because technique scheme is used, the utility model compared with prior art has following advantages and effect:

The utility model heat-resistant ultraviolet truck data cable, it had both improve digital communication cable fire resistance, also improve digital communication cable insulation property, and the raised line of insulating jacket layer embeds in the groove of described fire-retardant sheath, avoid the defect of the easy layering of connecting sewing, improve adhesive strength, reduce the difficulty of cable working technology, improve properties of product reliability; Secondly, four strands comprise to round metal conductor in line the first aluminum-alloy wire that is positioned at center, 6 second aluminum-alloy wires are stranded in the first aluminum-alloy wire surrounding formation outer conducting layer, its have lightweight, lay facility, cost is low, overcome the defects such as copper cost is high, price rises and fall sharply and quickly and aluminium mechanical performance is low, connection is unstable, flexility significantly improves, and makes the bending radius of cable be only 7 times of external diameters, improves the tensile strength of cable.
