Embodiment 1
[0025] Such as figure 1 As shown, a plug for an audio interface of a mobile phone includes an audio plug body and a plug cap 5, and the audio plug body includes a first electrode 1, a second electrode 2, a third electrode 3, a fourth electrode 4, and a first insulating layer 8. The second insulating layer 7 and the third insulating layer 6 . The first insulating layer 8 is between the first electrode 1 and the second electrode 2, the second insulating layer 7 is between the second electrode 2 and the third electrode 3, and the third insulating layer is between the third electrode 3 and the fourth electrode 4. insulating layer6. The end of the first electrode 1 is the top end, the plug cap 5 is the tail end, and the first electrode 1 to the fourth electrode 4 are sequentially exposed on the surface of the audio plug body from the top end to the tail end. The first electrode tail end 11 , the second electrode tail end 21 , the third electrode tail end 31 and the fourth electro...

The present invention relates to the field of the mobile phone accessory, especially to a plug for a mobile phone audio interface. The plug comprises a first electrode, a second electrode, a third electrode, a fourth electrode, a first insulation layer, a second insulation layer and a third insulation layer, wherein the first electrode, the second electrode, the third electrode and the fourth electrode are exposed from the surface at the plug body from the top end to the bottom end. The tail end of the second electrode, the tail end of the third electrode and the first electrode are zoomed down into the fourth electrode, the length of the tail end of the plug is greatly shortened on the original basis, and the fourth electrode itself play a protection effect on the tail ends of other electrodes. As everyone knows, the longer of the object, the easier to bend, the thickness of the tail end of the plug with the original structure changes from thick to thin, and therefore, the plug with the original structure is easier to break and damage in the usage to seriously influence the service life of the plug. According to the technical scheme, the length of the plug is obviously shortened and can be shorter 8-10mm than a general electronic component plug at most so as to facilitate usage.
Description
technical field [0001] The invention relates to the technical field of mobile phone accessories, in particular to a design of a plug used for a mobile phone audio interface. Background technique [0002] The existing external accessories of mobile phones, such as earphones and selfie sticks, are equipped with plugs for inserting into the audio interface of mobile phones. The structures are similar, including several exposed ring-shaped metal sheets separated by insulating materials. insulated from each other. For the four-level plug, taking the common four-level earphone plug as an example, the middle part of the fourth electrode is generally provided with a stepped structure, the tail end of the third electrode extends from the tail end of the fourth electrode, and the tail end of the second electrode extends out the tail end of the third electrode, and the tail end of the first electrode extends out from the tail end of the second electrode. Therefore, the length of the ...
