Abstract
A bending-resisting and hauling-resisting isolated earphone wire comprises a conductor, an insulating layer outside the conductor, an isolating layer outside the insulating layer and a coated layer outside the isolating layer. The isolated earphone wire is characterized in that a copper foil wire (1) is arranged beside filler cellosilk (2) of the conductor (3); the outside of the conductor is coated with the insulating layer (4); the isolating layer (6) for winding the conductor and comprising cellosilk (5), the copper foil wire (7) and cellosilk (9) is arranged outside the insulating layer (4); and the coated layer (8) is arranged outside the isolating layer (6). In the earphone wire, by adding the copper foil wire beside the conductor filler, the bending-resisting and hauling-resisting capabilities of the wire can be enhanced; and by uniformly adding the copper foil wire and the cellosilk in the isolating layer, so that the bending resistance and the hauling resistance of the isolating layer can be improved on the premise of keeping favorable shielding effect, the wire can be protected and the service life of the wire can be prolonged.
Description
Technical field
The utility model relates to electric wire, is the anti-isolation earphone cord that draws that hangs of a kind of anti-bending specifically.
Background technology
For isolating earphone cord, daily too much waving, bend or hang and draw, to cause the fracture of its coiled conductor separator, it is single stressed that reason is that coiled conductor belongs to, and such fracture will cause the wire rod antijamming capability to decline to a great extent or lose, reduce the signal quality of earphone cord, shorten the useful life of earphone cord.
Summary of the invention
The purpose of this utility model provides the anti-isolation earphone cord that draws that hangs of a kind of anti-bending.
The anti-isolation earphone cord that draws that hangs of described anti-bending, comprise conductor, outer outer separator, the outer coating of separator of insulating barrier, insulating barrier of conductor, it is characterized in that: there is copper foil wire on the filler fiber silk side of described conductor, outside conductor, be coated with insulating barrier, fibre-bearing silk, copper foil wire and filametntary coiled conductor separator are arranged outside insulating barrier, coating is arranged outside separator.
Described conductor is following one of several: enamel-cover twisted wire, bare copper stranded wire and zinc-plated twisted wire.
Described separator is following one of several: enamel-cover single line, bare copper wire and tinned wire.
Described filament is nylon yarn or Huang Dansi.
Described filament, copper foil wire and filament are along evenly equidistant arrangement the on 360 ° of circles of coiled conductor separator.
Described coating is PVC polyvinyl chloride or the plastic elastomer of TPE heat.
Earphone cord of the present utility model is by increasing copper foil wire on conductor filled thing side; strengthen the anti-bending and the anti-ability of drawing of hanging of wire rod; by in separator, evenly increasing copper foil wire and filament; make it under the prerequisite that keeps good shielding; improve the separator bend resistance and resist to hang and draw performance; wire rod there is defencive function, increases the useful life of wire rod.
Description of drawings
Fig. 1 is the utility model cross-sectional structure schematic diagram.
Among the figure: 1-copper foil wire, 2-filament, 3-conductor, 4-insulating barrier, 5-filament, 6-separator, 7-copper foil wire, 8-coating, 9-filament.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified: the anti-isolation earphone cord that draws that hangs of anti-as shown in fig. 1 bending, there is copper foil wire 1 on filler fiber silk 2 sides that comprise conductor 3, outside conductor 3, be coated with insulating barrier 4, the coiled conductor separator 6 of fibre-bearing silk 5, copper foil wire 7 and filament 9 is arranged outside insulating barrier 4, coating 8 is arranged outside separator 6.
Described conductor 3 is following one of several: enamel-cover twisted wire, bare copper stranded wire and zinc-plated twisted wire.
Described coiled conductor separator 6 is following one of several: enamel-cover single line, bare copper wire and tinned wire.
Described filament 2, filament 5 and filament 9 are nylon yarn or Huang Dansi.
Described filament 5, copper foil wire 7 and filament 9 are along evenly equidistant arrangement the on 360 ° of circles of coiled conductor separator.
Described coating 8 is PVC polyvinyl chloride or the plastic elastomer of TPE heat.
At the other copper foil wire that increases of the filler fiber silk of conductor; strengthen the anti-bending and the anti-ability of drawing of hanging of wire rod; by along evenly equidistant copper foil wire and the filament arranged on 360 ° of circles of coiled conductor separator; make it under the prerequisite that keeps good shielding; it is stressed that part has been shared in equilibrium; improve the bend resistance and anti-the hanging of separator and draw performance, wire rod is had defencive function, increase the useful life of wire rod.
