Description
Technical field
The present invention relates to Cellphone Accessories technical fields, more particularly to the setting of a kind of plug for mobile audio interface
Meter.
Background technique
Existing mobile phone external accessory, it is provisioned for being inserted into the plug of mobile audio interface such as earphone and self-shooting bar,
Structure is all similar, including several exposed annular sheet metals, is separated between sheet metal by insulating materials, sheet metal is mutual
Between insulate.For the plug of level Four, by taking the headset plug of common level Four as an example, platform is typically provided in the middle part of the 4th electrode
Stage structure, the tail end of tail end the 4th electrode of stretching of third electrode, the tail end of the tail end stretching third electrode of second electrode, first
The tail end of electrode stretches out the tail end of second electrode.So that general plug tail end length is nearly 10mm, cause earphone whole
Volume is larger, not easily contained, and since plug tail end is longer, is easy to be broken off damage.
Summary of the invention
The present invention provides a kind of inserting for mobile audio interface for the too long disadvantage of plug tail end in the prior art
Head.
Plug construction common in the art is that the tail end of third electrode stretches out the tail end of the 4th electrode, second electrode
Tail end stretches out the tail end of third electrode, and the tail end of first electrode stretches out the tail end of second electrode, and final plug tail end is in outstanding.
So that general plug tail end length is nearly 10mm, storage is inconvenient.It is well known that object length more longer easier bending,
And the plug tail end of original structure is from the coarse to fine, therefore is easier in use because fractureing damage, and seriously affecting plug makes
Use the service life.And the existing technology for shortening plug tail end length does not still make big innovation in structure, it only will be every
The length of one electrode shortens.The present invention is solved since plug tail end is too long, caused by it is inconvenient for use, it is difficult to store,
And the problem of being easily damaged, the 4th electrode length is constant in present design, and second electrode tail end, third electrode tail end are contracted
To the 4th electrode, the structure of plug tail end is changed, highly shortened the length of plug tail end on the basis of original,
And tail end diameter remains unchanged, while the 4th electrode itself also plays protective effect to other electrode tail ends.Using this skill
After art scheme, plug length is obviously shortened, and is more convenient to use, while the more difficult damage of plug, is effectively extended plug
Service life.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals:
