Abstract
A bending-resistant isolation headphone wire includes conductors with insulating layers, isolation layers outside the conductors, and coating layers outside the isolation layers, and is characterized in that the isolation layer (2) winding the conductor (1) is arranged outside the conductor (1) with the insulating layer, the coating layer (3) is arranged outside the isolation layer (2), the conductor (4) with the insulating layer is arranged outside the coating layer (3), the isolation layer (5) is arranged outside the coating layer (3) and the conductor (4), the coating layer (7) is arranged outside the isolation layer (5), and a nylon yarn winding layer (6) is arranged between the isolation layer (5) and the coating layer (7). In the headphone wire of the utility model, the outer layer isolation layer is wound by a layer of nylon yarn, so that the isolation layer is held tightly and stressed evenly, the bending resistance of the wire is enhanced for protecting the wire, and the service life of the wire is prolonged.
Description
Technical field
The utility model relates to electric wire, is a kind of isolation earphone cord 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 a kind of isolation earphone cord of anti-bending.
The isolation earphone cord of described anti-bending, outer separator, the outer coating of separator of conductor, conductor that comprises the tape insulation layer, it is characterized in that: the conductor of described tape insulation layer has the coiled conductor separator outward, coating is arranged outside separator, the conductor that the tape insulation layer is arranged outside coating, the coiled conductor separator is arranged outside coating and the conductor, coating is arranged outside separator, the nylon yarn winding layer is arranged between separator and coating.
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 coating is PVC polyvinyl chloride or the plastic elastomer of TPE heat.
Earphone cord of the present utility model is held separator tightly by twining one deck nylon yarn outside the separator outside, makes it stressed evenly; strengthen the anti-bending ability of wire rod; anti-the hanging that has strengthened wire rod to a certain extent drawn performance, and wire rod is had 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-conductor, 2-separator, 3-coating, 4-conductor, 5-separator, 6-nylon yarn winding layer, 7-coating.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified: the isolation earphone cord of anti-bending as shown in fig. 1, the conductor 1 that comprises the tape insulation layer, outside conductor 1, be wound with conductor isolation layer 2, coating 3 is being arranged outside the separator 2, conductor 4 is being arranged outside coating 3, outside coating 3 and conductor 4, twined conductor isolation layer 5, coating 7 is arranged outside separator 5, between separator 5 and coating 7, nylon yarn winding layer 6 is arranged.
Described conductor 1 and conductor 4 are following one of several: enamel-cover twisted wire, bare copper stranded wire and zinc-plated twisted wire.
Described separator 2 and separator 5 are following one of several: enamel-cover single line, bare copper wire and tinned wire.
Described coating 3 and lining 7 are PVC polyvinyl chloride or the plastic elastomer of TPE heat.
Go up winding one deck nylon yarn (nylon yarn winding layer) at outer coiled conductor (outer separator), the winding direction of coiled conductor is opposite with the winding direction of nylon yarn.The nylon yarn winding layer makes separator and whole wire rod hold tightly, makes it stressed evenly, strengthens the anti-bending ability of wire rod, and anti-the hanging that has strengthened wire rod to a certain extent drawn performance, and wire rod is had defencive function, increases the useful life of wire rod.
Claims (4)
