Description

A kind of Teflon shielding earphone cable

Technical field

The utility model relates to earphone cable fields, and in particular to a kind of Teflon shielding earphone cable.

Background technique

Earphone (Earphones; Headphones; Head-sets;It Earpieces) is a pair of of converting unit, it connects The electric signal issued by media player or receiver converts it into the sound that can be heard using the loudspeaker close to ear Wave.Earphone is usually separable with media player, and a plug is utilized to connect.Benefit is the case where not influencing other people Under, sound equipment can be listened to alone；Also the sound that ambient enviroment can be separated, in recording studio, DJ, journey, movement etc. in noisy environment of making an uproar The lower people used is helpful.Earphone original is used on phone and radio, but prevailing with portable electronic devices, Earphone is chiefly used in mobile phone, walkman, radio, portable electronic game sum digit reproducing apparatus for phonotape etc..

Earphone cable is indispensable for earphone, existing TPE or TPU earphone cable, structure are as follows: conductor+insulation+ Twisted pair wire+shielding+outer quilt.Conductor uses oxygen-free copper, and core insulation and outer insulated use TPE or TPU.Wire rod is easy to beat Knot, resist bending and resistance to twisting property are undesirable.Conventional TPE or TPU earphone cable is intolerant to torsion and bending.Resistance to number of torsions is less than 2 It just only thread-changing or scraps for ten thousand times, service life is short, and signal transmission performance is general.

Utility model content

The purpose of this utility model is that it is in view of the drawbacks of the prior art and insufficient, a kind of Teflon shielding earphone is provided Line, the performance with high resist bending and torsion can be well protected core wire, and signal transfers performance and is significantly larger than existing product well Can, earphone cable has a safety feature, and high temperature resistant is resistance to fire-retardant, it is not easy to generate heat, long product lifecycle.

To achieve the above object, the utility model is using following technical scheme: it includes the outer quilt of Teflon ETFE insulation 1, winding layer 2, shielded layer 3, PTFE belting layer 4, conductor 5, twisted pair wire 6, Teflon ETFE insulating layer 7, the conductor 5 are resistance to torsion The gun-metal line turned, the conductor 5 have two, and two conductors 5 are symmetrical arranged about the earphone cable neutral conductor, outside the conductor 5 It is enclosed with Teflon ETFE insulating layer 7, two 5 front and back of conductor are symmetrically arranged with two twisted pair wires 6 about the earphone cable neutral conductor, The conductor 5 and twisted pair wire 6 are wrapped with PTFE belting layer 4, and PTFE belting layer 4 is wrapped with shielded layer 3,3 outsourcing of shielded layer It is wrapped with winding layer 2, it is outer by 1 that winding layer 2 is wrapped with Teflon ETFE insulation.

The twisted pair wire 6 is 250D nylon yarn filling line.

The Teflon ETFE insulation is quilt outside the insulation of the copolymer of ethylene and tetrafluoroethene by 1 outside.

The Teflon ETFE insulating layer 7 is the insulating layer of the copolymer of ethylene and tetrafluoroethene.

The winding layer 2 is woven by copper wire.

The shielded layer 3 is foil shielding layer.

After adopting the above technical scheme, the utility model has the beneficial effect that the performance with high resist bending and torsion, it can be very Good protection core wire, signal transfer performance and are significantly larger than existing product performance well, and earphone cable has a safety feature, high temperature resistant, resistance to resistance Combustion, is not easy to generate heat, long product lifecycle.

Detailed description of the invention

In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property It puts, is also possible to obtain other drawings based on these drawings.

Fig. 1 is the schematic perspective view of the utility model；

Fig. 2 is the cross section structure schematic diagram of the utility model.

Description of symbols: Teflon ETFE insulation it is outer by 1, winding layer 2, it is shielded layer 3, PTFE belting layer 4, conductor 5, right Twisted wire 6, Teflon ETFE insulating layer 7.

Specific embodiment

Referring to shown in Fig. 1-Fig. 2, present embodiment the technical solution adopted is that: it includes that Teflon ETFE insulation is outer By 1, winding layer 2, shielded layer 3, PTFE belting layer 4, conductor 5, twisted pair wire 6, Teflon ETFE insulating layer 7, the conductor 5 is resistance to The gun-metal line of torsion, the conductor 5 have two, and two conductors 5 are symmetrical arranged about the earphone cable neutral conductor, the conductor 5 It is wrapped with Teflon ETFE insulating layer 7, two 5 front and back of conductor are symmetrically arranged with two twisted pair wires about the earphone cable neutral conductor 6, the conductor 5 and twisted pair wire 6 are wrapped with PTFE belting layer 4, and PTFE belting layer 4 is wrapped with shielded layer 3, outside shielded layer 3 It is enclosed with winding layer 2, it is outer by 1 that winding layer 2 is wrapped with Teflon ETFE insulation.

The twisted pair wire 6 is 250D nylon yarn filling line.Nylon has very high mechanical strength, and softening point is high, heat-resisting, rubs Wiping coefficient is low, wear-resistant, self-lubrication, shock absorption and sound-deadening properties, oil resistant, weak acid resistant, alkaline-resisting and common solvent, electrical insulating property It is good, there is self-extinguishment, nontoxic, odorless, good weatherability, dyeability is poor.The disadvantage is that water imbibition is big, dimensional stability and electrical property are influenced Can, fiber reinforcement can reduce resin water absorption rate, can work under high temperature, high humidity.Nylon and glass fibre affinity are very Well.

The Teflon ETFE insulation is outside the outer quilt of the copolymer of ethylene and tetrafluoroethene insulation by 1.

The Teflon ETFE insulating layer 7 is the copolymer insulating layer of ethylene and tetrafluoroethene.Teflon high temperature resistant, resistance to resistance Combustion.

The winding layer 2 is woven by copper wire.

The shielded layer 3 is foil shielding layer.

Working principle of the utility model is: using gun-metal as the conductor of wire rod, with high resist bending and torsion Performance；Using the PTFE band with extremely strong toughness, core wire can be well protected, the outer quilt in addition Teflon insulate, resistance to torsion Turning number can reach 200,000 times or more, will not have knotting phenomenon, the use of Teflon ETFE be ethylene and tetrafluoroethene Copolymer, high temperature resistant are resistance to fire-retardant.

The above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, those of ordinary skill in the art couple The other modifications or equivalent replacement that the technical solution of the utility model is made, without departing from technical solutions of the utility model Spirit and scope should all cover in the scope of the claims of the utility model.
