Disclosure of Invention
In view of the deficiencies in the prior art, the utility model provides a soft anti nuclear electromagnetic pulse computer cable, this cable both can anti nuclear electromagnetism and can carry out signal transmission, have that hardness is little, low-loss, electric insulating property is good, characteristics such as anti nuclear electromagnetic pulse of while.
The utility model discloses a realize above-mentioned purpose, the technical scheme who takes is: a soft nuclear electromagnetic pulse resistant computer cable comprises a twisted pair, an electromagnetic shielding layer, an outer shielding layer and a sheath;
and the twisted pairs form a cable core, and an anti-electromagnetic shielding layer, an outer shielding layer and a sheath are sequentially arranged outside the cable core.
The utility model has the advantages that: the conductor and the inner shielding layer are made of tinned round copper wires, and the copper has high conductivity, so that interference can be reduced, and signal transmission of the cable is guaranteed.
The fluorinated ethylene propylene insulating layer has excellent dielectric strength, good electrical insulation, high temperature resistance level and the maximum working temperature of the conductor can reach 200 ℃.
The shielding layer adopts a weaving combination form, different metal materials are compounded to form a plurality of shielding reflection interfaces, the shielding efficiency of the cable can be improved, the alloy wires are adopted to replace alloy belts, the flexibility is increased, and the cable is easy to bend when in use. The high-permeability alloy wire electromagnetic shielding layer has high permeability and plays a role in shielding at a low frequency, and meanwhile, compared with a common tinned copper wire, the tinned copper clad aluminum has the characteristics of low density and light weight, so that the weight of the cable can be reduced while the performance is ensured.
The protective sleeve adopts TPR elastomer, has better mechanical environment performance, good mildew resistance, high and low temperature resistance, good flame retardant property, salt mist resistance, damp and heat resistance, artificial atmospheric aging resistance, wear resistance and softness.
The cable has the advantages of good insulating property, high voltage resistance, flexibility, 5 times of cable outer diameter of the minimum bending radius, 70dB of nuclear electromagnetic pulse resistance, and good transmission performance and nuclear electromagnetic resistance.
The cable can resist nuclear electromagnetism and can transmit signals at the same time, has excellent transmission performance and low loss, adopts a braided alternative structure, enables the cable to have excellent nuclear electromagnetism resistance under the condition of strong interference, and is soft, light in weight and convenient to use.
