Problems solved by technology

[0002] Computer control cables usually use good electric conductors as shielding materials, which have obvious anti-interference effect on high-frequency signals, but for some low-frequency and strong electromagnetic field interference areas, ordinary computer control cables are no longer competent for normal signal transmission and anti-interference The high requirements of high requirements will often cause some signal distortions, which will lead to equipment malfunction and major accidents in severe cases; therefore, it is necessary to design a new structure for the computer control cable structure and materials, so that the computer control cable can operate in high and low frequency bands, It has strong anti-interference performance in the environment of high-intensity electromagnetic field, and it also needs to have the performance of fireproof, waterproof, compressive and tensile

Abstract

The invention discloses a shielded cable for waterproof computer control, wherein a rubber skeleton comprises four circular skeletons with different radii sizes, the left end sides of the four circular skeletons are fixedly connected together and then nested in order according to the radii sizes, first cores are provided in all the four circular skeletons, two second cores are further provided inthe second circular skeleton, two second cores and two third cores are further disposed in the third circular skeleton, two second cores and four third cores are further disposed in the fourth circular skeleton, and the first cores comprise first conductors. In the shielded cable, protrusions set on the skeletons can make the positions of the cores more stable and difficult to change, the waterproof canvas taped covering has good waterproof effect, the inner sheath layer of lead alloy can be used as a waterproof sheath to ensure that the cable core conductors are protected from moisture wet attack, the coated asphalt can improve seawater corrosion resistance, the pearlescent sand composite filling layer has good fireproof and heat insulation effect, and the ethylene-propylene rubber elastic rod increases the cable softness.
