Abstract
The utility model relates to a shielded cable for a computer, which comprises a plurality of conductor groups. Each conductor group consists of two conductor cores. The two conductor cores are covered by an insulating layer. Each conductor group is covered by a pair-twisted group lapping layer. The external side of each pair-twisted group lapping layer is covered by a pair-twisted group shielding layer. A filling rope is arranged on the internal side of the pair-twisted group shielding layer. The pair-twisted group lapping layers are sequentially covered by a lapping layer, a metal shielding layer and an outer sheath layer. Fillers are arranged between the lapping layer and each pair-twisted group shielding layer. The metal shielding layer is woven by copper wires. Since the fillers are additionally arranged between each pair-twisted group shielding layer and the pair-twisted group shielding layer, the shielded cable for the computer has the advantages of more compact structure, convenience in manufacturing, good shielding performance, excellent anti-aging performance and long service life.
Description
Technical field:
The utility model relates to computer cable, relates in particular to a kind of computer with shielded type cable (comprising the DCS cable).
Background technology:
