Abstract

The utility model discloses a flat tensile tear-resistant multifunctional soft cable for a drag chain. A structure of an insulating cable core is arranged in the following way that a conductor is formed by concentrically twisting a plurality of soft copper single wires with 2-7 steel wires with diameters being the same as those of the soft copper single wires; a conductor insulating layer on the surface of the conductor is made of a butyronitrile complex or a tensile silicon rubber material; an insulating cable core protecting jacket on the surface of the conductor insulating layer adopts a high-strength wrapping belt; a plurality of insulating cable cores are arranged linearly at intervals; two sides are respectively provided with a wire rope with a diameter of 1.0-6.0 mm; and the wire ropes are extruded together with a thermoplastic polyether type elastomer to form an outer protecting layer. The flat tensile tear-resistant multifunctional soft cable for the drag chain has favorable over-all properties such as flexibility, tensile performance, tear resistance, wear resistance, oil resistance, weathering resistance, low-temperature stability, compact structure and the like, and can adapt to various different work environments.

Description

The multi-functional drag chain flexible cable of a kind of flat tension tear-proof

Technical field

The utility model relates to electric wire, a kind of drag chain flexible cable of more specifically saying so.

Background technology

Along with the raising that equipment performance requires, advance in mobile drive system such as car tipper, coal-winning machine etc., with electric wire tension, wear-resisting, weather, oil resistant, requirement such as in light weight are arranged for coordinative composition of equipments.As electrical installations such as car tipper, coal-winning machines, require that instrument and meter connecting line volume is little, electrical insulation capability good, it is strong to bear overload capacity, and requirement has favorable mechanical physical property, electric property, have characteristics such as softness, tension, tear-proof, wear-resisting, oil resistant, weatherability, low-temperature stability, structure be tight, safety guarantee is had relatively high expectations.But existing normal cable can not satisfy this requirement well.

The utility model content

The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of combination property that can possess characteristics such as have softness, tension, tear-proof, wear-resisting, oil resistant, weatherability, low-temperature stability, structure are tight is provided, can adapts to the multi-functional drag chain flexible cable of flat tension tear-proof of multiple different operational environment.

The utility model technical solution problem adopts following technical scheme:

The multi-functional drag chain flexible cable of a kind of flat tension tear-proof, the structure that insulated wire cores is set is: conductor adds 2～7 steel wire concentric strandings identical with described soft copper filament diameter by many soft copper monofilament and forms; The insulating layer of conductor of conductive surface adopts butyronitrile compound or tension silastic material, and the insulated wire cores sheath of conductor insulation laminar surface adopts the high strength twining package tape; The edge cores that thoroughly do away with become a word interval to arrange more, and the steel wire rope that it is 1.0mm～6.0mm that respectively there is a diameter on both sides forms outer jacket with the extruding of thermoplastic polyether type elastomer jointly.

Be extruded with the steel wire rope insulating barrier on the surface of described steel wire rope.

Described conductor is the 5th kind or the 6th kind of conductor that meets GB/T 3956.

Described conductor adopts regular concentric stranding structure, and the twisted wire pitch is 10-14, and the sectional area of conductor is 1.5～185mm ²

The core number of described insulated wire cores is 2～14 cores.

Compared with the prior art, the utility model beneficial effect is embodied in:

1, conductor adds the steel wire concentric stranding by the soft copper monofilament in the utility model, can prevent effectively that conductor is because of the infringement of high intensity phenomena such as crooked, as to move to conductor, the useful life of effectively having improved conductor.Simultaneously, zinc-plated form can be adopted in the copper wire surface, also has to prevent this oxidation under high/low temperature condition of conductor, increases fail safe and reliability in the use;

2, in the utility model in the insulated wire cores in steel wire and the cable steel wire rope the effective tensile strength of cable and number of times that the cable reversed bending moves of having improved be set, drag chain uses can be greater than 5,000,000 times cycle-index; More embodied because the raising of intensity can be adopted the occupation mode of suspension, be very easy to use;

3, insulating layer of conductor makes it have following performance by adopting butyronitrile compound or tension silicon rubber in the utility model:

(1) You Yi heat-resisting and resistance to low temperature;

(2) higher fire resistance;

(3) good electrical insulation properties;

(4) good tear-proof and wear-resisting, oil resistant;

(5) You Yi chemical stability and corrosion resistance;

4, the insulated wire cores sheath material adopts thermoplastic polyether type elastomer in the utility model, and its anti-wear performance reaches 45mm ³, hot strength reaches 42Mpa, and elongation reaches 790%, and tearing strength reaches 65KN/m, and Shao Er hardness is 88A;
