Abstract

The utility model discloses an anti-ageing flexible cable which includes a nylon center wire, a conductor, and an insulating wire core. A cable core is composed by a fire-proof wire core, a fire-proof wire core II and the nylon center wire; the cable core is wrapped by an inner cushion layer; a shielding layer formed by weaving of a tinned flexible single copper wire is arranged outside the inner cushion layer; an outer sheath layer is extruded outside the shielding layer; the shielding layer is internally provided with a multi-strand tinned flexible current guide wire; the fire-proof wire core comprises three insulating wire cores and is wrapped by a fireproof layer; and the fire-proof wire core II is formed by two insulating wire cores and is wrapped by a fire-proof layer II. In the utility model, the tinned flexible single copper wire is used to make the conductor and the shielding layer, so as to effectively prevent the aging and catalyzing effect of the copper conductor on the insulating layer and sheath, and the service life of the insulating layer and sheath is ensured. At the same time, the surface of the flexible single copper wire is tinned, so that the oxidation of the flexible single copper wire conductor and the shielding layer can be effectively prevented, and the safety and reliability in use are improved.

Description

A kind of anti-aging flexible cable

technical field

The utility model relates to a kind of anti-aging flexible cable, belongs 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.

utility model content

It is a kind of simple in structure that the utility model provides, and has 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 utility model adopts zinc-plated soft copper monofilament to form, can prevent the aging catalytic action of copper conductor to insulating barrier and sheath, effectively to ensure 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.
