Abstract
The invention discloses an anti-aging soft cable. The anti-aging soft cable comprises a nylon center line, a conductor and an insulating line core. A cable core is composed of a fireproof line core, a fireproof line core II and the nylon center line. A lining layer is arranged outside the cable core in a wrapping mode, a shielding layer formed by weaving tinned soft copper monofilaments is arranged outside the lining layer, an outer protection sleeve layer is arranged outside the shielding layer in a squeezing mode, a multi-strand bundled soft tinned current guide line is arranged in the shielding layer, and the fireproof line core is formed by arranging a fireproof layer on three combined insulating line cores in a wrapping mode. The fireproof line core II is formed by arranging a fireproof layer II on two combined insulating line cores in a wrapping mode. According to the anti-aging soft cable, due to adoption of the conductor and shielding layer composed of tinned soft copper monofilaments, the aging catalysis of the copper conductor on insulating layers and protection sleeves can be effectively avoided to guarantee the service life of the insulating layers and the service life of the protection sleeves. Meanwhile, because the surface of the soft copper monofilaments is tinned, the oxidation of the soft copper monofilaments and the oxidation of the shielding layer can be effectively avoided, and safety and reliability are improved in the using process.
Description
technical field
The present invention relates to a kind of anti-aging flexible cable, belong to technical field of electric wires and cables.
background technology
Shielded flexible cable is to use conductive fabric, the transmission line that netted braided wire wraps up holding wire.There is the wire of conductor parcel wire outside shielding conductor, the conductor of parcel is screen, be generally conductive fabric, braiding copper mesh or copper pool (aluminium), screen needs ground connection, external interference signal can be imported the earth by this layer, avoids interference signal and enters inner conductor and disturb the loss that simultaneously reduces signal transmission.
summary of the invention
The invention provides one simple in structure, there is good not aging, flexibility, the fire-proof shield flexible cable of long service life.
A kind of anti-aging flexible cable, comprise nylon center line, conductor, insulated wire cores, cable core is made up of the core of preventing fires, fire prevention core II and nylon center line, described cable core wrapped fluoroplastics inner covering successively outward, described inner covering is provided with the screen of zinc-plated soft copper monofilament braiding outward, also push at screen the external sheath layer that one deck adopts ceramic fireproof silicone rubber to make outward, in described screen, be provided with the soft zinc-plated channelizing line that a multiply bundle closes, described fire prevention core is made up of three rear wrapped fireprotection layers of being made up of employing fire prevention mica tape of insulated wire cores combination; Described fire prevention core II is made up of two rear wrapped fireprotection layer II of being made up of employing fire prevention mica tape of insulated wire cores combination, and described insulated wire cores forms insulated wire cores by the outer wrapped polyvinyl chloride insulation layer of conductor.
Described conductor adopts and meets the 5th kind of tinned copper conductor structure in GB/T3956, and the sectional area of conductor is 0.2～6mm
2, it is 10～16 times that bundle closes pitch.
Conductor and screen that the present invention adopts zinc-plated soft copper monofilament to form, can prevent the aging catalytic action of copper conductor to insulating barrier and sheath, effectively to guarantee the useful life of insulating barrier and sheath.Meanwhile, also can effectively prevent the oxidation of soft copper monofilament conductor and shielding itself at the electroplating surfaces with tin of soft copper monofilament, increase the safety and reliability in use procedure.Oversheath adopts the extrusion modling of ceramic silicon rubber, and it has the chemical resistance of wide range.
accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
