Problems solved by technology

[0003] The function of shielded cables is mainly to prevent electrostatic interference, electromagnetic induction and crosstalk induction interference, and ensure that the transmission system is running upwards. For computer cables used in special environments and temperatures, they need to achieve good transmission performance, resistance to specific environments, and stability. Strong, high security features, but the cables in the prior art can not meet the above conditions

Abstract

The invention discloses an anti-radiation flexible cable containing an aluminum tape shielding layer for a computer and a manufacturing method of the anti-radiation flexible cable. The cable comprisesa conductor cable core, a shielding cable core, an aluminum tape shielding layer and a protective sleeve; the conductor cable core comprises a conductor wire core, and an inner semiconductive shielding layer, a crosslinked polyethylene shielding layer, an outer semiconductive shielding layer, a metal shielding layer and a protective layer which wrap the conductor wire core in sequence; the shielding cable core comprises an insulating wire core and a tinned fine and soft copper wire layer braided outside the insulating wire core, the coverage rate of the copper wire layer reaches 70% or above,and the pitch diameter of the shielding cable core is required not to be larger than that of the conductor cable core. The aluminum tape shielding layer is in a spoke shape, one conductor cable coreis arranged at the position, close to the center of the shielding layer, in an area limited between every two adjacent aluminum tape shielding layers, a plurality of shielding cable cores are arrangedat the position away from the center of the shielding layer, the aluminum tape shielding layer is wrapped by the protective sleeve, and the cable has a good shielding effect, and is wide in application range and high in safety.

Description

technical field [0001] The invention relates to the technical field of cable manufacturing, in particular to a radiation-resistant flexible cable for computers with an aluminum tape shielding layer and a manufacturing method thereof. Background technique [0002] Computer cables are spare cables for electrical appliances. They are suitable for fixed connection of computers, testing instruments, and fixed instruments with AC voltage below 500v and high anti-interference performance requirements. The shielding function of the cable directly affects the performance of the above components. [0003] The function of shielded cables is mainly to prevent electrostatic interference, electromagnetic induction and crosstalk induction interference, and ensure that the transmission system is running upwards. For computer cables used in special environments and temperatures, they need to achieve good transmission performance, resistance to specific environments, and stability. Strong, hi...
