Abstract
The utility model discloses a computer flexible cable with a flame retardant polyolefin insulation elastomer rubber sheath. The flexible cable comprises a plurality of conductor groups. Each of the plurality of conductor groups is formed by twisting two soft copper conductors and a strengthening core together, wherein the two soft copper conductors are wrapped with an insulating layer separately. Each of the plurality of conductor groups is wrapped with an inner belting layer and a sub shielding layer successively. The plurality of conductor groups and a filling belt are twisted together to form a cable core having a circular cross section, wherein each of the conductor groups is wrapped with the sub shielding layer. The cable core is wrapped with a middle belting layer, a general shielding layer, an outer belting layer and a sheath layer made from an elastomer rubber material successively. The flexible cable of the utility model has a simple and reasonable structure design. Each of the conductor groups is formed by twisting the insulation wire core and the strengthening core together, and the inner winding layer, the middle winding layer, the outer winding layer and the middle longitudinal cladding are adopted at the same time, so the cable has characteristics of good flame retardant performance, low smoke, halogen-free, environmental protection, good heat resistance, ageing resistance, anti-electromagnetic interference, flexibility, easy laying, etc.
