Abstract

The invention discloses a high-temperature-resistant shielding type computer cable. The computer cable comprises a rubber framework; the rubber framework comprises a sawtooth edge-shaped annular framework; V-shaped plates are fixedly connected to sawtooth concave corners on the outer side of the annular framework to form a plurality of quadrilateral cavities; three oval frameworks are arranged inside the annular framework in parallel; a first wire core is arranged inside the oval framework in the middle; second wire cores are arranged inside the two oval frameworks located on the two sides; apearlife composite filling layer fills each oval framework; and a third wire core is arranged in each quadrilateral cavity. The outer side of the rubber framework is sequentially coated with a glass fiber tape and ceramic silicone rubber tape wrapping layer, a carbon black paper insulation shielding layer, a waterproof canvas wrapping layer and an EVM rubber outer sheath, so that the performancesof flame retarding, insulation shielding, water resistance, high temperature resistance and the like of the cable are greatly improved.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a high temperature resistant shielded computer cable. Background technique [0002] Computer cables are cables for electrical equipment. This cable is suitable for electronic computers and automation instruments with a rated voltage of 500V and below that require high anti-interference. With the expansion of the application range of flame-retardant wires and cables, some electronic and electrical products that require high flexibility require the use of environmentally friendly, low-smoke, flame-retardant insulation or sheathed wires and cables, thus putting forward new requirements for flame-retardant cables. [0003] In the prior art, the high temperature resistant computer cable is not suitable for adding an armor layer, and its shielding effect cannot meet the requirements. Contents of the invention [0004] The object of the present invention is to provide a high temperatu...
