Abstract
The utility model discloses a kind of tension earphone cable, including core, the core includes conducting wire and strengthening core, and the conducting wire is formed by more soft structure conductor strands, and is coated with internal shield and inner insulating layer successively, and the conducting wire ring-type is distributed in earphone cable；The strengthening core is distributed between the center of earphone cable and the conducting wire；External shielding layer and external insulation layer are enclosed with successively outside the core, and cotton fiber filler is filled between the core and the external shielding layer；The strengthening core is alkali-resistant glass fibre beam.The utility model adds strengthening core, and wherein a strengthening core is arranged on the center of core, enhances the tensile strength of earphone cable, extends its service life.
Description
Technical field
The utility model belongs to technical field of electric wires and cables, more particularly to a kind of tension earphone cable.
Background technology
With the development and popularization of electronic product, earphone is also widely used as the accessory of electronic product,
Earphone not only allows people to liberate both hands and does some other things, but also in public, and earphone both can be to avoid bothering
Others, and prevent from being bothered by others.Although wireless headset is had occurred in the people visual field, wired earphone is still with it
The advantage of itself continues in occupation of most of market.Due to the particularity of earphone, its cable cannot be made to too slightly, but again
Ensure its tensile strength.Therefore, it is necessary to be badly in need of designing a kind of tension earphone cable, to meet the needs of people.
Utility model content
To solve the above problems, the purpose of this utility model is to provide a kind of tension earphone cable, the tension of earphone cable is improved
Intensity, extends the service life of earphone cable.
A kind of tension earphone cable, including core, the core include conducting wire and strengthening core, and the conducting wire is by more soft structures
Conductor strand forms, and is coated with internal shield and inner insulating layer successively, and the conducting wire ring-type is distributed in earphone cable；It is described to add
Strong core is distributed between the center of earphone cable and the conducting wire；External shielding layer and external insulation layer are enclosed with successively outside the core,
Cotton fiber filler is filled between the core and the external shielding layer.
Further, the strengthening core is alkali-resistant glass fibre beam.
Further, the material that the external insulation layer is selected is thermoplastic polyurethane elastomer rubber.
A kind of tension earphone cable of the utility model, compared with prior art, its advantage is：1. the utility model exists
Strengthening core is added in earphone cable, strengthening core is alkali-resistant glass fibre beam, and in the centrally disposed strengthening core of core, is enhanced
The tensile strength of earphone cable, and have the characteristics that resist bending, elasticity are good, extend the service life of earphone cable；2. a practicality is new
Type is strengthened shield effectiveness, is improved the anti-interference energy of earphone cable using the effect of internal shield and external shielding layer dual shield
Power.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model tension earphone cable.
Shown in figure, 1- conducting wires, 2- strengthening cores, 3- internal shields, 4- inner insulating layers, 5- cotton fibers filler, 6- external screens
Cover layer, 7- external insulation layers.
Embodiment
The principle and feature of the utility model are described with reference to embodiments, illustrated embodiment is served only for explaining this
Utility model, is not intended to limit the scope of the utility model.
As shown in Figure 1, a kind of tension earphone cable, including core, the core include conducting wire 1 and strengthening core 2, the conducting wire
1 is formed by more soft structure conductor strands, and is coated with internal shield 3 and inner insulating layer 4 successively, 1 annular distribution of conducting wire
In in earphone cable；The strengthening core 2 is distributed between the center of earphone cable and the conducting wire 1；It is enclosed with successively outside the core
External shielding layer 6 and external insulation layer 7, are filled with cotton fiber filler 5 between the core and the external shielding layer 6.
Further, the strengthening core 2 is alkali-resistant glass fibre beam.
Further, the material that the external insulation layer 7 is selected is thermoplastic polyurethane elastomer rubber.
The utility model adds its strengthening core of alkali-resistant glass fibre Shu Zuowei in earphone cable, and is rationally provided with and strengthens
The position of core, effectively enhances the tensile strength of earphone cable, and the utility model has the characteristics that resist bending, elasticity are good.
The scope of protection of the utility model is not limited to the technical solution disclosed in embodiment, every according to this practicality
New technical spirit each falls within the guarantor of the utility model to above example any modification, equivalent replacement, improvement and so on
Protect scope.
