Abstract

A computer bilayer shielding cable braided with copper clad aluminum wires comprises a sheath layer, a braided shielding layer, an extruded layer and three pairs of copper conductors inside the sheath layer. Each pair of copper conductors consists of two copper conductors, each copper conductor is wrapped by an insulation layer, a cavity of each pair of copper conductors is wrapped by an inner extruded layer, an inner shielding layer is arranged outside the inner extruded layer, a grounding wire is arranged between the inner shielding layer and the inner extruded layer, the extruded layer is arranged inside the sheath layer and wrapped by the braided shielding layer, and the three pairs of copper conductors respectively occupy one third of a cavity of the sheath layer and are arranged circumferentially in an abutted manner. The computer bilayer shielding cable braided with the copper clad aluminum wires has the advantages that external non-signal high-frequency current can be shielded when the cable is used for transmitting computer signal current, so that the transmitted signal current is ensured not to be interfered, and the shielding layers braided with the copper clad aluminum wires can be protected from atmospheric corrosion and mechanical damage.

Description

A kind of double-deck copper-clad aluminum conductor braided shield cable that is used for computer
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of double-deck copper-clad aluminum conductor braided shield cable that is used for computer.
Background technology
Copper belongs to a kind of strategic resource, and the shielding material of computer shield cable is a copper, and its cost is higher.Because the non-signal high-frequency current of the main screening effect computer of this cable, high-frequency current can produce " kelvin effect " by time on the conductor, and promptly electric current only flows through at conductive surface; If adopt the screen of copper-clad aluminum conductor braiding, the non-signal high-frequency current of conductively-closed is the appearance copper layer of collection skin at copper-clad aluminum conductor, flow out through earth connection, shield effectiveness is with identical with the screen of solid copper wire braiding, but the copper-clad aluminum conductor price is that solid copper wire is below 50%, this will help computer and declines to a great extent with the price of double-deck copper-clad aluminum conductor cable, and performance is constant, therefore can improve towards this direction.
The utility model content
At above defective, the purpose of this utility model provide a kind of cheap, save copper product, can avoid the double-deck copper-clad aluminum conductor braided shield cable that is used for computer of atmospheric corrosion and mechanical damage, to solve many deficiencies of prior art.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of double-deck copper-clad aluminum conductor braided shield cable that is used for computer, comprise restrictive coating, establishment screen, extrude layer and three pairs of copper conductors of restrictive coating inside, every pair by two copper conductors compositions, each copper conductor outer wrap one layer insulating, cavity outside, every pair of copper conductor place is wrapped with and extrudes layer in one deck, should in extrude a layer outside and be provided with internal shield, described internal shield and in extrude and be connected to earth connection between the layer; Described restrictive coating inboard is provided with one deck and extrudes layer, and this extrudes layer outside parcel one deck woven shield.The three pairs of copper conductors account for three of sheath lumen/abut against together by circumferential arrangement in the lump respectively, described copper conductor is that solid annealed copper wire and its sectional area scope are 0.5 square millimeter-2.5 square millimeters, described insulating barrier, extrude layer with in extrude layer by wherein a kind of composition of polyethylene, crosslinked polyethylene or halogen-free and low-smoke flame-retardant polyolefin, described earth connection is solid annealed copper wire and is affixed on the lapping layer appearance and lays along cable length.
The beneficial effect that is used for the double-deck copper-clad aluminum conductor braided shield cable of computer described in the utility model is: when structure is provided with, main passing through with single copper conductor extruded insulation layer, again every pair of copper conductor is wrapped up and extruded layer, extrude layer outer surface and add a copper earth connection along cable length, and wrapping up the screen of copper-clad aluminum conductor braiding thereon, the three pairs of copper conductors abut against together and wrap up and extrude layer by respectively accounting for 120 ° of circumferential arrangement; Extrude layer outer surface and add a copper earth connection again along cable length, and then extrude restrictive coating behind the screen of parcel copper-clad aluminum conductor braiding, overall structure can realize that cable has shielded outside non-signal high-frequency current when carrying the Computer signal electric current, guaranteed that the signal code of carrying is interference-free, the screen of copper-clad aluminum conductor braiding can be avoided atmospheric corrosion and mechanical damage.
Description of drawings
According to embodiment and accompanying drawing the utility model is described in further detail below.
Fig. 1 is the described double-deck copper-clad aluminum conductor braided shield cable structural representation that is used for computer of the utility model embodiment.
Among the figure:
1, copper conductor; 2, insulating barrier; 3, extrude layer; 4, earth connection; 5, woven shield; 6, extrude layer in; 7, internal shield; 8, restrictive coating.
Embodiment
As shown in Figure 1, the double-deck copper-clad aluminum conductor braided shield cable that is used for computer described in the utility model, comprise restrictive coating 8, establishment screen 5, extrude 3 and three pairs of copper conductor 1 of layer, described restrictive coating 8 inside are provided with three pairs of copper conductors 1, and these three pairs of copper conductors 1 account for three of sheath lumen/abut against together by circumferential arrangement in the lump respectively; Every pair by two copper conductors, 1 composition, each copper conductor 1 outer wrap one layer insulating 2; Cavity outside, every pair of copper conductor 1 place is wrapped with and extrudes layer 6 in one deck, extrude layer 6 outside in this and be provided with internal shield 7, described internal shield 7 with in be connected to earth connection 4 between extruding layers 6; Described restrictive coating 8 inboards are provided with one deck and extrude layer 3, and this extrudes layer 3 outside parcel one deck woven shield 5.The effect that overall structure embodied is, at first, and " collection skin " phenomenon, promptly the high-frequency signal electric current in the screen copper line surface flows out by earth connection, the screen of copper-clad aluminum conductor braiding is outer coated sheath again, and this screen is hedged off from the outer world, and avoids copper-clad aluminum conductor to be subjected to atmospheric corrosion and mechanical damage.
More than the double-deck copper-clad aluminum conductor braided shield cable that is used for computer described in the utility model, described copper conductor 1 is that solid annealed copper wire and its sectional area scope are 0.5 square millimeter-2.5 square millimeters, described insulating barrier 2, extrude layer 3 with in extrude layer 6 by wherein a kind of composition of polyethylene, crosslinked polyethylene or halogen-free and low-smoke flame-retardant polyolefin, described earth connection 4 is for solid annealed copper wire structure and be affixed on the lapping layer appearance and lay along cable length, and described restrictive coating 8 can be made up of flame-proof polyvinyl chloride or halogen-free and low-smoke flame-retardant polyolefin.
