Abstract

The utility model discloses a high-temperature-resistant super category-5 communication cable, which comprises a conductor, a cable core and a sheath. The outside of the conductor is coated with an insulating layer made of non-polar high-temperature-resistant material. Two leads are arranged in the cable core. Two solid filling strips are intertwisted between the two leads to form the cable core. The outside of the cable core is coated with a double-layer shielding layer. The outside of the double-layer shielding layer is coated with the outer sheath made of fluoroplastic material. According to the technical scheme of the utility model, the cable is more flexible, thus being better in transmission performance. Meanwhile, the attenuation effect of the cable is reduced. The cable can bear a temperature high up to 200 DEG C and the shielding rate of the cable is up to 100%. In this way, the signal attenuation is relieved and the interference of external electromagnetic waves on the cable is avoided at the same time. Therefore, the impedance of the cable is more stable and the transmission attenuation is smaller. The high-temperature-resistant super category-5 communication cable can be used for the transmission of LVDS signals sent by electronic devices in various special environments.

Description

The high temperature resistant five class telecommunication cables that surpass

Technical field:

The utility model relates to a kind of novel fire resistant and surpasses five class telecommunication cables, more specifically says that a kind of electronic device being mainly used in rugged environment provides highly reliable LVDS signal transmission super category 5 cable.

Background technology:

Conventional super category 5 cable in the market, employing be that single naked copper core is done inner wire, polyolefin is as insulation, polyvinyl chloride is made sheath, the resistance to ambient temperature of cable is only-15 ℃～70 ℃, is only applicable to common occasion simultaneously, have under the severe occasion of the environment such as greasy dirt, sunshine inapplicable.To user, use and brought inconvenience like this.

Utility model content:

The utility model is for avoiding the existing weak point of above-mentioned prior art, a kind of high temperature resistant five class telecommunication cables that surpass are provided, make cable there is high-low temperature resistant, decay little, the novel fire resistant that can use under adverse circumstances surpasses five class telecommunication cables, makes it be particularly suited for the transmission of electronic device LVDS signal under various particular surroundingss.

In order to solve the existing problem of background technology, the utility model is by the following technical solutions: a kind of high temperature resistant five class telecommunication cables that surpass, include conductor, cable core, sheath, conductor is coated with the insulating barrier of nonpolar exotic material, in cable core, be provided with two wires, stranded between two wires have two hatching solid bar shapeds to become cable core, cable core is coated with double layer screen layer, double layer screen layer is coated with fluoroplastics oversheath, the internal layer screen of double layer screen layer is aluminium-plastic tape screen, the outer screen of double layer screen layer is braiding silver-coated copper wire screen.

Conductor is 19 stranded forming of ф 0.12mm silver-coated copper wire, the aluminium of aluminium-plastic tape screen towards outside, the aluminium of aluminium-plastic tape screen towards outside, the wire netting of braided metal net screen is silver-coated copper wire.

Operation principle of the present utility model is: adopted 19 stranded conductors that form of ф 0.12mm silver-coated copper wire, insulating barrier at the nonpolar exotic material of conductor outer cladding as wire, by solid the extruding of nonpolar exotic material, form packing, two wires and two packings are twisted together by certain pitch, skin arranges double layer screen layer, internal layer screen in double layer screen layer is wrapped metal compound belt screen, outer screen is braided metal net screen, extexine at cable is coated fluoroplastics as oversheath, to be that silver-coated copper wire is stranded form conductor, improved cable transmission performance, reduced signal attenuation, the outer coated nonpolar exotic material of conductor, this material dielectric constant is 2.1, dielectric loss angle tangent is only 0.0002, simultaneously, material heatproof is-60 ℃～200 ℃, reduced like this product external diameter, decay is less simultaneously, cable has had high and low temperature resistance, double layer screen layer adopts aluminium-plastic tape+metal net double layer screen, unlined aluminium plastic composite strip aluminium towards outside, outer layer metal silk has adopted silver-coated copper wire, has improved like this screening effectiveness, has improved cable heat-resisting quantity simultaneously.

Conductor be by 19 ф 0.12mm silver-coated copper wires according to the structural arrangement of 1+6+12, direction of lay is left-hand, conductor is compared with rounding like this; Insulation adopts nonpolar exotic material to be wrapped on conductor by melt extruding mode, concentricity requirement >=95%.Make like this impedance uniformity of cable reach splendid effect; Packing has adopted that nonpolar exotic material is solid to be extruded, and dielectric constant is 2.1, and this and insulative dielectric constant are consistent, and cable is compared with rounding simultaneously, and in cable shield, dielectric constant is very even, to reach the object of impedance equalization; Metal tape screen adopts aluminium-plastic tape, the rate of putting up of the wrapped employing 50% of aluminium-plastic tape, and aluminium towards outside, this version forms good contacting between the wire netting of aluminium face and outer braid metal mesh shield layer, the charge inducing that can effectively conduct aluminium foil surface, reaches excellent shield effectiveness.

Compared with the prior art, the utility model beneficial effect is embodied in: conductor has adopted 19 stranded forming of ф 0.12mm silver-coated copper wire, cable is more soft, the silver-plated copper stranded wire adopting, make cable transmission performance better, decay less, heatproof can reach 200 ℃ simultaneously, adopted the wrapped double layer screen mode that adds braid shielded of aluminium-plastic tape, can make cable reach the effect of 100% shielding, reduced signal attenuation, resist the interference of external electromagnetic ripple to cable simultaneously, having adopted nonpolar exotic material to do insulate, make cable resistance more stable, transmission attenuation is less, be applicable to the transmission of electronic device LVDS signal under various particular surroundingss.
