Abstract
The utility model discloses a flexible cable for an extraordinary electric welding machine. The flexible cable is characterized in that a low-carbon high-molecular fireproof insulator layer is wrapped on the outer side of a conductor; and a soft fiber isolation layer, a shielding body and a sheath are sequentially arranged on the outer side of the insulator layer in an extrusion way. The shielding body has a three-layer structure. The inner layer is composed of aluminum magnesium alloy wires. The middle layer is composed of plastic-aluminum composite films. The outer layer is composed of iron nickel alloy belts. By adopting the low-carbon high-molecular fireproof insulator layer and further adopting the three-layer composite shielding structure composed of aluminum magnesium alloy wires, plastic-aluminum composite films and iron nickel alloy belts, the flexible cable which is light and has good flame resistance achieves low electromagnetic interference in real use. The flexible cable is more suitably used for extraordinary electric welding machines.
Description
Technical field
The utility model belongs to the cable technology field, is specifically related to a kind of extraordinary electric welding machine flexible cable.
Background technology
Cable on existing electric welding machine, owing to existing flexibility poor, therefore easily produces some unnecessary troubles in use procedure, and affects useful life.For this reason, Chinese patent CN201220514699.X discloses the soft type electric welding machine of a kind of spy cable.Mainly solve existing electric welding machine and exist flexibility poor with cable, bending flexibly, thereby the problem of to use, making troubles.This cable comprises conductor, sheath, and described conductor is positioned at sheath and encloses, and is provided with the soft fibre separator between described sheath and conductor.The advantage of this technical scheme is between conductor and sheath to adopt the fiber separator, thereby makes cable have flexibility preferably, therefore in use, bending flexibly, easy to use.But, also there is an obviously deficiency, that is: weight is heavier, poor fire, and the performance of electromagnetic pulse-resisting is not good, can produce electromagnetic interference in actual applications.
The utility model content
The purpose of this utility model is to provide a kind of extraordinary electric welding machine flexible cable of new construction, and it is lightweight, good flame resistance not only, and in practical application, electromagnetic interference is little, is more suitable for extraordinary electric welding machine and uses.
For realizing this purpose, the technical solution of the utility model is: a kind of extraordinary electric welding machine flexible cable, described conductor outer wrapping is hanged down carbon macromolecule refractory thermal insulator layer, described insulator layer is extruded with soft fibre separator, shield, sheath outward successively, described shield is three-decker, internal layer is aluminum-magnesium alloy wire, and intermediate layer is plastic-aluminum combined film, and skin is the iron-nickel alloy band.
As preferably, described conductor is by multiply nickel plating soft copper silk stranded forming in the same way.
, as preferably, be provided with a dimity braiding reinforced layer between described shield and sheath.
As preferably, described sheath is comprised of wrinkle composite steel-plastic belt moisture-proof layer and the black polyethylene sheath of vertical bag overlap joint.
With respect to prior art, the utility model selects low carbon macromolecule refractory thermal insulator layer to substitute Mica tape+insulating barrier in the past, not only possesses good mechanical and physical performance, has possessed simultaneously excellent fire resistance.adopt aluminum-magnesium alloy wire, three layers of composite shielding structure of plastic-aluminum combined film and iron-nickel alloy band, almag is placed on innermost layer, a little less than utilizing its magnetic, the characteristics that density is little, can not produce interference and effectively alleviate cable weight, and the iron-nickel alloy band is a kind of strong magnetic material, can effectively overcome the interference of high-intensity magnetic field, with plastic-aluminum combined film as in ask that layer can effectively shield on the one hand, also can isolate on the other hand aluminum-magnesium alloy wire and iron-nickel alloy band, prevent that both from producing coupling effect, influence each other and offset magnetic screen, greatly promoted electromagnetic pulse-resisting performance of the present utility model.Arrange between screen and restrictive coating by some dimity braiding reinforced layers, and by wrinkle composite steel-plastic belt moisture-proof layer and the black polyethylene sheath of vertical bag overlap joint, form oversheath, its mechanical strength is better, and fire resistance also greatly promotes.
Description of drawings
Fig. 1 is the utility model cross-sectional view.
Wherein: 1 is conductor, and 2 is sheath, and 3 is the soft fibre separator, and 4 is shield, and 5 is insulator layer.
Embodiment
In conjunction with the embodiments the utility model is further illustrated with reference to the accompanying drawings.
As shown in Figure 1, a kind of extraordinary electric welding machine flexible cable, described conductor outer wrapping is hanged down carbon macromolecule refractory thermal insulator layer, described insulator layer is extruded with soft fibre separator, shield, sheath outward successively, described shield is three-decker, internal layer is aluminum-magnesium alloy wire, and intermediate layer is plastic-aluminum combined film, and skin is the iron-nickel alloy band.Wherein, described conductor is by multiply nickel plating soft copper silk stranded forming in the same way; Be provided with a dimity braiding reinforced layer between described shield and sheath; Described sheath is comprised of wrinkle composite steel-plastic belt moisture-proof layer and the black polyethylene sheath of vertical bag overlap joint.
The improvement that the utility model is done with the construction of cable mainly for extraordinary electric welding machine, the foregoing is only the utility model preferred embodiment, non-so namely limit to the scope of the claims of the present utility model, therefore simple and easy variation and the equivalent transformation of such as with the utility model specification and graphic content, doing, all should be contained in the scope of the claims of the present utility model.
