Description

The inner connection flat copper cash of a kind of electric welding machine

Technical field

The utility model relates to welding machine cable field, particularly the inner connection flat copper cash of a kind of electric welding machine.

Background technology

At present, along with economy and industrial expansion, electric welding machine is used in increasing place, such as the fields such as building, machine-building all need to use electric welding machine, electric welding machine is that the high-temperature electric arc that utilizes positive and negative polarities to produce when instantaneous short circuit carrys out scolder and the materials to be welded on consumable electrode, reach the object that makes their combinations, therefore electric welding machine can produce large electric current, therefore, electric welding machine is in order to save inner space, reduce volume, weight reduction, usually adopts all good flat type copper wires of conductivity, thermal conductivity and corrosion resistance in electric welding machine inside.Yet the flat type copper wire flexibility adopting is at present poor, therefore in use easily fracture, increases electric welding machine maintenance cost, shortens the electric welding machine life-span, and is unfavorable for reducing the volume of electric welding machine, weight reduction.

Utility model content

The utility model, for the defect existing in prior art and deficiency, provides a kind of electric welding machine inner connection flat copper cash.

The technical solution adopted in the utility model is: the inner connection flat copper cash of a kind of electric welding machine, comprise conductor, semiconductor water blocking layer, insulating barrier and sheath, described conductor forms through soft copper skein silk combined pressure type, conductor outside is enclosed with semiconductor water blocking layer, described semiconductor water blocking layer outside is surrounded with insulating barrier, and described insulating barrier is wrapped with sheath.

In said structure, described semiconductor water blocking layer consists of outward wrapped the putting up at conductor of semiconductor waterstop, and the wrapped rate of putting up is 30% ~ 40%.

In said structure, described conductor forms by several strands of strands are stranded, and stranded lay ratio is 8 ~ 10.

Further, described multiply strand is formed by several soft copper tow strands respectively.

In said structure, described insulating barrier by polypropylene film respectively wrapped putting up in semiconductor water blocking layer outside form, the wrapped three-layer polypropylene film of putting up.

In said structure, described sheath consists of wrapped the putting up in insulating barrier outside of semiconductive brown paper, and the wrapped rate of putting up is more than 50%.

Good effect of the present utility model:

1, structurally the inner connection flat copper conductors of the utility model electric welding machine forms through soft copper skein silk combined pressure type, and stranded lay ratio is controlled between 8-10, product increases the pliability of cable, saves electric welding machine inner space, improve the flexible back-shaped performance of cable, reduce electric welding machine volume.

2, structurally, the outer wrapped one deck semiconductive waterstop of conductor of the inner connection flat copper cash of the utility model electric welding machine, semiconductive waterstop is put up rate between 30-40%, and even conductor electromagnetic field, is subject at cable under the environment of moisture or moisture content, waterstop meeting instantaneous expansion, effectively stop moisture intrusion, corrosion cable, thereby the life-span of improving cable, reduce fault and occur, save maintenance cost.

3, structurally, the insulating barrier of the inner connection flat copper cash of the utility model electric welding machine adopts that polypropylene film is wrapped to be formed, and the wrapped number of plies is three layers, and polypropylene screen, with superior insulation property, has increased flexibility, the insulating properties of cable.

4, structurally, the sheath material of the inner connection flat copper cash of the utility model electric welding machine adopts semiconductive brown paper, and the rate of putting up is controlled at more than 50%, while preventing that cable is subject to wound, Leakage Current causes casualties, has reduced the weight of cable, has alleviated the weight of electric welding machine.

4, in sum, the inner connection flat copper cash of the utility model electric welding machine has the inner key property with cable of welding of common welder simultaneously, there is again water preventing ability, uniform electric field, high-insulativity, leakage-preventing electric current, flexibility, reduced cable cost, dwindle cable usage space, because this cable relates in process of production, do not extrude operation, saved electric energy and the loss of water energy in production process, reduce production costs; This flat type copper wire is widely used in the inner connection such as ac arc wedling machine, DC welding machine, argon arc welding machine, CO2 shield welder, butt welding machine, spot welding machine, submerged arc welding machine, applied widely.
