Abstract

The utility model relates to the improvement of a power cord for moving, in particular to a power cord which is not easily twisted, winded and broken wire in the process of repeatedly using. The utility model is characterized in that two or more continuous length single lines are arrayed in parallel, an outer coating layer is extruded out, and the cross section of the power cord is led to be in a non-circular special shape. The twisting and winding of a root are eliminated in the process of using, and the and the twisting and winding of an electrical wire not easily happen in the process of frequently moving and repeatedly using, and therefore, the broken of single filament of a conductor can not happen, the service span of the power cord is greatly prolonged, and the use security is greatly improved. With the method, the manufacture cost of an electrical line is not increased, parallel and interphase conductors directly extrude the outer coating layer, and the outer coating layer is only needed to be extruded out in one time, the extruding efficiency is improved, a cabling is not needed to be stranded, and the man-hour and manufacturing cost can be lowered.

Description

Move and use power line

Technical field

Utility model is use power line to moving, and for example the household electrical appliance electric iron is with the improvement of power line, particularly a kind of mobile power line of using of the coiling fracture of wire that is difficult for being distorted in use repeatedly.

Background technology

For example move that electric iron, electric iron, electric cutting by stranded flexible conductor stranded stranding behind extruded insulation, apply sheath with power line (three cores or four-core) then, what have increases braid again outside sheath.This stranded stranding power line, because of twining mutually between the insulated wire cores, the stranding process has certain torsional moment to exist, and moves in the use frequent, and the distortion that occurs electric wire through regular meeting is reeled.And this type of power line conductor is generally all by many thin monofilament stranded compositions, and the frequent excessive distortion of electric wire is reeled, and single wire fracture in the conductor can occur when serious, and then the insulation of stabbing, and causes potential safety hazard.

The open 1986-11092 of Korean Utility Model discloses a kind of reinforcing agent that the coupling part forms between electric wire and plug body, and a kind of bad protection of the line loss that pipe is arranged part that extends back and form with reinforcing agent; Chinese patent CN1855640 is disclosed in power line and plug protection tube inner surface forms the gap.What they related to all is to handle at power line and plug coupling part, prevents that protection tube from separating with the coupling part.Chinese patent CN2807560 proposes to adopt rotary socket, plug-in unit can be rotated, the damage of avoiding the power line excessive distortion to cause in notch.Chinese patent CN2194916 etc. propose to adopt the power line unwinding and rewinding, avoid the power line distortion to fracture.Though above-mentioned these all are the coilings that is distorted when avoiding electric wire to use, but all not relating to the anti-distortion of power line itself reels, still can not eliminate torsion in the stranding process, distortion still can appear in power line reels, so the problems referred to above can thoroughly be eliminated.

The utility model content

The utility model purpose is to overcome the deficiency of above-mentioned prior art, and a kind of cost that do not increase is provided, and is easy to process, the mobile power line of using of the coiling fracture of wire that is difficult for being distorted in move using repeatedly.

The utility model purpose realizes that main the improvement is that the stranded stranding of insulated wire cores is extruded sheath, change into single line be arranged in parallel (not stranded) extrude serving, thereby eliminate stranded stranding torsional moment, and the cross section adopts non-round structure, thereby the generation of thoroughly stopping to twist coiling realizes the utility model purpose.Specifically, utility model moves uses power line, comprises two and above continuous length single line, and serving, it is characterized in that said two and above continuous length single line are arranged in parallel, and has extruded serving outward, and to make the power line cross section be non-circle abnormity.

The said single line of utility model can have two kinds of forms, and a kind of for having the insulated single wire of insulation, they can adjacently be arranged; A kind of is bare conductor single line (naked), they then alternately, by the serving that the extrudes embedding isolation of being insulated.

Said serving is looked combination single line difference, and its serving function is also different, and for example making up single line is insulated single wire, and then serving can adopt protective cover material, is bare conductor as the combination single line, and then serving adopts Insulation Material.

Said non-circle is special-shaped, is meant the general designation of power line cross section other random geometries except that circular, and for example the cross section can be triangle, flat, ellipse, square, polygon or other non-circular shapes or other non-circular shapes.The non-round abnormity in cross section is relatively circular, is difficult for producing distortion and reels in frequent moving.

According to using needs, can also outside serving, increase braid as prior art, for example fiberglass braided layer.

Utility model moves uses power line, after only single line is arranged in parallel (merging), directly extrude serving, thereby do not have stranded torsional moment, and the non-circle abnormity that is reeled for difficult distortion in the electric wire cross section, distortion coiling root produced in the use thereby eliminated, in frequently moving, using repeatedly, be difficult for taking place the distortion coiling of electric wire, thereby also just the conductor monofilament can not take place and fracture, not only prolonged power line useful life greatly, and safety in utilization improves greatly also.And the method does not increase the electric wire manufacturing cost, and alternate conductor arranged side by side directly extrudes serving, only need once extrude and improve extrusion efficiency, can reduce the manufacturing cost in man-hour; In addition, do not need stranded stranding, can reduce the stranding cost again.Utility model moves uses power line, can be used as various frequent movable electrical appliances electric power connection lines and uses.

Below in conjunction with six specific embodiments; utility model is further understood in exemplary illustration and help; but the embodiment detail only is for utility model is described; do not represent utility model design whole technical schemes down; therefore should not be construed as the technical scheme qualification total to utility model, some do not depart from the unsubstantiality of utility model design and change In the view of the technical staff; for example change or replace, all truely use novel protected scope so that technical characterictic with same or similar technique effect is simple.
