Abstract

The utility model discloses an earphone wire, which comprises a conducting wire and an insulating cladding covering the conducting wire; the earphone wire further comprises a buffering wire; the buffering wire is insulated from the conducting wire; and the overall length of the buffering wire is smaller that that of the conducting wire. The buffering wire with the length smaller than that of the conducting wire is added in the earphone wire, so that when the earphone wire is under an external pulling force, the external pulling force is applied on the buffering wire to protect the conducting wire, which prevents the conducting wire from being damaged, enhances the mechanical strength of the earphone wire, and prolongs the service life of the earphone wire.

Description

A kind of earphone cord

[technical field]

The utility model relates to a kind of earphone cord, relates in particular to a kind of Novel earphone line that self has cushioning effect.

[background technology]

Along with progress of science and technology, the use of the multimedia audiovisual amusement equipment of carrying is also more and more general, and the earphone of collocation use also is an indispensable part with it.Existing earphone mainly contains wired earphone and wireless headset, though wireless headset has advantages such as easy to use, because its cost is higher, and self need be provided with shortcomings such as power supply, therefore, wired earphone still is one of irreplaceable amusement equipment annex.

Present wired earphone mainly comprises earphone cord, earplug and is positioned at the loudspeaker of earplug, plucking as people in the process of earphone, often directly catch the part of earphone cord that earplug is taken with hand, be easy to like this junction of earphone cord and earplug inside trumpet is disconnected, cause earphone normally not use.In addition; people are when the audiovisual entertainment content; people usually can be placed on amusement equipment certain position of human body; for example be suspended on the neck; yet when being suspended on amusement equipment on the neck by earphone cord, earphone cord must bear certain pulling force, causes the line between earphone cord and the amusement equipment to damage through regular meeting; earphone is damaged, shortened the useful life of earphone undoubtedly.

[utility model content]

The utility model provides a kind of Novel earphone line, has set up alignment buffer on this earphone cord, and for earphone cord bears extraneous pulling force, it is bad to prevent that earphone cord from being drawn.

For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions:

A kind of earphone cord, it comprises: call wire and be coated on the outer insulating coating of this call wire, this earphone cord also comprises alignment buffer, insulate between this alignment buffer and the described call wire, the length of described alignment buffer is less than the length of described call wire.

Described call wire comprises many cores.

Described alignment buffer is between many cores of described call wire.

Many cores of described call wire are axle with described alignment buffer, are wrapped on this alignment buffer.

After twisting together mutually, many cores of described call wire are wrapped on the described alignment buffer.

Be filled with the insulating properties object in many cores of described call wire and the space between the described alignment buffer.

Described alignment buffer is made with the insulation material.

Described insulating coating is the thermoplastic polyester elastomer coating layer.

Be filled with thermoplastic polyester elastomer in the gap between described call wire and the described alignment buffer.

Described alignment buffer is many, and these alignment buffers are centered around around the described call wire.

Earphone cord of the present utility model has following advantage:

By in existing earphone cord, increasing alignment buffer; like this when earphone cord is subjected to extraneous pulling force; because the length of call wire is greater than the entire length of alignment buffer; therefore, this external tensile force is born by alignment buffer, and can not put on the call wire; call wire is protected; guarantee the normal transmission of data message, effectively prolonged the useful life of earphone cord, strengthened the mechanical strength of earphone cord.

[description of drawings]

Fig. 1 is the cross sectional representation of earphone cord of the present utility model.

[embodiment]

Reach technological means and the effect that predetermined purpose is taked for further setting forth the utility model, below in conjunction with drawings and Examples, embodiment, architectural feature and effect thereof to a kind of Novel earphone line of the present utility model are described in detail as follows.

As shown in Figure 1, be the cross sectional representation of earphone cord of the present utility model.This earphone cord comprises call wire 1, alignment buffer 3 and is arranged on call wire 1 and alignment buffer 3 insulating coating 2 outward.Described call wire 1 comprises many cores, is used for transmitting data information.Insulate between described alignment buffer 3 and the described call wire, and be arranged between the many cores of described call wire 1, and this alignment buffer does not carry out data information transmission, is used to cushion the pulling force that is applied on the call wire, prevents that call wire is damaged owing to external tensile force is excessive.The entire length of the described call wire of being made up of many cores 1 is greater than the entire length of described alignment buffer 3.

Particularly, in the present embodiment, many cores of described call wire 1 are axle with described alignment buffer 3, are wrapped in respectively on the described alignment buffer 3, and insulate between every core and the alignment buffer 3.Described alignment buffer 3 can be made for insulation materials such as plastics, also can fill the insulating properties material in the gap between described call wire 1 and the described alignment buffer 3, insulate between alignment buffer 3 and the call wire 1 guaranteeing.

In another embodiment, be wrapped in again on the described alignment buffer 3 after many cores of described call wire 1 twist together mutually.Owing to insulate between described alignment buffer 3 and the described call wire 1, therefore can not influence call wire 1 transmission signals.

In the preferred embodiment, described insulating coating 2 is a thermoplastic poly ester elastomer coating layer, and can in many cores of call wire 1 in twos between the core and and described alignment buffer between the gap in fill thermoplastic polyester elastomer, guarantee to insulate between core and the alignment buffer, so not only can avoid after core is coated insulating varnish, being processed in the prior art phenomenon that produces the surface lacquer membrane damage in the process of call wire, and can strengthen the insulation property of call wire, and the time with earphone cord of the present utility model and other components and parts welding processing, can directly go up tin processing, and need not before processing, to take peeling to go up the technology of tin again, can guarantee crudy again when having saved processing cost, and effectively prolong the useful life of earphone cord.

The thinnest 0.03mm that reaches of the thickness of described thermoplastic polyester elastomer coating layer has guaranteed that not only the external diameter of earphone cord is enough little, and can guarantee call wire good insulation performance performance.

During concrete enforcement, described alignment buffer also can be many, and these alignment buffers are positioned at all sides or a side of described call wire, so that strengthen the endurance of entire headset line.

Below only embodiment of the present utility model is described, but be not that various variations or the modification made according to the utility model spirit are all within the protection category of claim of the present utility model in order to restriction the utility model.
