Description
Technical field
The present invention relates to Cellphone Accessories technical field, particularly relate to setting of a kind of plug for mobile audio interface
Meter.
Background technology
Existing mobile phone external accessory, such as earphone and self-shooting bar, provisioned is used for inserting the plug of mobile audio interface,
Structure is the most similar, including the annular sheet metal that several are exposed, is separated by insulant between sheet metal, and sheet metal is mutual
Between insulate.For the plug of level Four, as a example by the headset plug of common level Four, the middle part of the 4th electrode is typically provided with platform
Stage structure, the tail end of the 3rd electrode stretches out the tail end of the 4th electrode, and the tail end of the second electrode stretches out the tail end of the 3rd electrode, and first
The tail end of electrode stretches out the tail end of the second electrode.Hence in so that general plug tail end length is nearly 10mm, cause earphone overall
Volume is relatively big, the most easily contained, and owing to plug tail end is longer, is easily broken off damaging.
Summary of the invention
The present invention is directed to the shortcoming that in prior art, plug tail end is long, it is provided that a kind of inserting for mobile audio interface
Head.
Plug construction common in the art is the tail end that the tail end of the 3rd electrode stretches out the 4th electrode, the second electrode
Tail end stretches out the tail end of the 3rd electrode, and the tail end of the first electrode stretches out the tail end of the second electrode, and final plug tail end is outstanding.
Hence in so that general plug tail end length is nearly 10mm, storage inconvenience.It is known that object length is the longest more easily bends,
And the plug tail end of original structure is from the coarse to fine, being therefore easier in use because fractureing damage, having a strong impact on plug and making
Use the life-span.And the technology of existing shortening plug tail end length still the most structurally makes big innovation, it is only will be every
The contraction in length of one electrode.The present invention solves owing to plug tail end is long, the use inconvenience caused, it is difficult to storage,
And the problem being easily damaged, in present design, the 4th electrode length is constant, by the second electrode tail end, the 3rd electrode tail end contracting
To the 4th electrode, change the structure of plug tail end, on the basis of original, highly shortened the length of plug tail end,
And tail end diameter keeps constant, and the 4th electrode itself also serves protective effect to other electrode tail ends simultaneously.Use this skill
After art scheme, plug length substantially shortens, more convenient use, simultaneously the more difficult damage of plug, effectively extends plug
Service life.
