The beneficial effect of above-mentioned structure is: the ground terminal of the audio connector adopts a hidden structure design, when the audio connector is installed in an electronic product, a user cannot see the ground terminal from a jack of the audio connector, so that the texture of the electronic product is improved, and the ground terminal, the annular B terminal, the tip terminal, the annular A terminal, the switch transmission terminal and the switch interruption terminal are reasonably distributed in the plastic shell, so that the thickness of the audio connector is reduced, and the working reliability of the audio connector is also improved. Therefore, the audio connector has the advantages of simple structure, compact structure, stable and reliable performance, stable and reliable connection and small volume.

Particularly, the plastic casing on correspond one side department of joint groove and be provided with the mounting panel, the mounting panel on be provided with the arc draw-in groove, and the plastic casing on correspond the opposite side department of mounting panel and be provided with the installation draw-in groove. With the mounting panel setting in one side of joint groove, the mounting panel can play the additional strengthening, has strengthened the bulk strength of plastic shell, is provided with the arc draw-in groove on the mounting panel to be convenient for this audio connector's installation.

Particularly, the ground terminal, the annular terminal B, the tip terminal, the annular terminal A, the switch transmission terminal and the switch interruption terminal are respectively provided with a pin, and the pins of the ground terminal, the annular terminal B, the tip terminal, the annular terminal A, the switch transmission terminal and the switch interruption terminal are respectively inserted on the circuit board and form the clamping fit of the ground terminal, the annular terminal B, the tip terminal, the annular terminal A, the switch transmission terminal and the switch interruption terminal with the circuit board. The ground terminal, the annular B terminal, the tip terminal, the annular A terminal, the switch transmission terminal and the switch interruption terminal are connected with the circuit board in a clamping fit mode, and therefore the audio connector and the circuit board can be assembled conveniently.
