High-heat-dissipation type computer cable

Abstract

The invention provides a high-heat-dissipation type computer cable, which comprises a cable core, an inner sheath layer, a shielding layer and an outer sheath layer. The inner sheath layer, the shielding layer and the outer sheath layer are sequentially wrapped outside the cable core. The cable core comprises a central wire core and N outer wire cores. A plurality of central conductive wires are distributed in the central cavity of an elastic framework in a circumferential mode, and the plurality of central conductive wires are tightly pressed against the inner periphery of the elastic framework. The elastic framework is arranged to fix the central conductive wires. The periphery of the elastic framework is closed, so that the external oil and gas is prevented from invading into the cable core. The oil-proof and waterproof performances of the cable are guaranteed. The service life of the cable is prolonged. The elastic framework is made of an elastic material, so that the flexibility of the cable is not affected at all. Meanwhile, the mechanical performance of the cable is enhanced. The heat generated during the working process of the central conductive wires can be transmitted to an elastic body through the elastic framework, and is emitted outwards by the elastic body. The thicknesses of the central conductive wires are gradually increased and then gradually decreased from one ends thereof closer to the center of the cable to the other ends thereof further away from the center of the cable. Therefore, the heat transfer speed can be increased. Moreover, the heat generated during the working process of the outer wire cores can be directly emitted outwards.
