Abstract
The utility model relates to the technical field of cable manufacturing, in particular to a double-layer shielded computer cable. The shielded computer cable comprises mutually-twisted insulated conductors, wherein at least one current drainage wire is twisted between the insulated conductors; an ALPET shielding layer, a braided shielding layer and a PVC (Poly Vinyl Chloride) sheath layer are sequentially arranged outside the insulated conductors; and the insulated conductors comprise twisted tinning wires which are externally wrapped by SR (Semi-Rigid)-PVC insulating layers. The shielded computer cable has the advantages that the transmission performance is good; the anti-external interference capability is strong; the high requirement of computer network on signal transmission is met; and the internal interference of the cable is reduced to the best, the shielding effect on external signal interference is achieved to ensure that the signal transmission is not distorted. The shielded computer cable is mainly suitable for computer cables.
Description
Technical field
The utility model relates to the cables manufacturing technical field, particularly a kind of shielding wire for PC.
Background technology
At present increasingly high with requiring of transmitting of cable signal to network; Because the internal interference of cable self also can influence the smooth transmission of signal; Existing network cable of the while shielding action of interference signal to external world is not very strong, causes the signal transmission to have the phenomenon of distortion at last.
Summary of the invention
The utility model provides a kind of double layer screen wire for PC, and purpose is to strengthen the shielding properties of the internal external interference signals of cable.
The utility model comprises stranded insulated electric conductor mutually, stranded at least one drain wire between said insulated electric conductor; Outside said insulated electric conductor, set gradually aluminium foil wheat drawstring screen, woven shield and PVC restrictive coating; Said insulated electric conductor comprises the twisted wire tin plated wire, at twisted wire tin plated wire outerwrap SR-PVC insulating barrier.
Good, the anti-external disturbance ability of the utility model transmission performance is strong, has satisfied the high request of computer network to the signal transmission, and it is best that the internal interference of cable self was dropped to, and also solved the shielding action that external signal is disturbed, and makes the signal transmission can distortion.The utility model is applicable to that mainly computer uses line.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Among the figure, 1, the twisted wire tin plated wire, 2, drain wire, 3, aluminium foil wheat drawstring screen, 4, the SR-PVC insulating barrier, 5, woven shield, 6, the PVC restrictive coating.
Embodiment
