Referring to the first to sixth embodiments, the audio connector 100 of the present invention includes an insulative housing 1 , a plurality of conductive terminals 2 received in the insulative housing 1 , and a gripping plate portion 3 mounted on the insulative housing 1 .

Referring to the third and fourth figures, the insulative housing 1 includes an annular head portion 11, a rectangular body portion 12, and a neck portion 13 connecting the head portion 11 and the body portion 12. The insulative housing 1 defines a receiving space 14 that penetrates the head portion 11 , the neck portion 13 , and the body portion 12 . The main body portion 12 defines a plurality of terminal slots 121 , and the terminal slots 121 communicate with the receiving space 14 . The body portion 12 is provided with a step portion 122 near the front end of the neck portion 13, and the grip plate portion 3 is provided. In the step portion 122. The neck portion 13 protrudes from the head portion 11 and the body portion 12. The insulative housing 1 defines an insertion interface on the head 11 for insertion of a mating connector (not shown), an end surface opposite the insertion interface, and a mounting surface adjacent to a printed circuit board (not shown). The plug interface defines the docking direction of the docking connector. The mounting surface of the insulative housing 1 is convexly provided with a stud 15 which, together with the gripping portion 3, fixes the audio connector 100 to the printed circuit board.

Referring to FIG. 3 to FIG. 6 , the conductive terminal 2 includes a first conductive terminal 21 and a second conductive terminal 22 protruding from the left side into the receiving space 14 , and a third protruding from the right side into the receiving space 14 . The conductive terminal 23 and the fourth conductive terminal 24 and the ground terminal 25 projecting into the receiving space 14 from above. The first conductive portion 21 includes a first holding portion 211 , a first soldering portion 212 bent from a bottom edge of the first holding portion 211 , and a first contact portion 213 protruding from the leading edge of the first holding portion 211 to the receiving space 14 . . The second conductive terminal 22 includes a second contact portion 221 and a rearward bifurcation extending from the second contact portion 221 to the upper arm portion 222 and the lower arm portion 223.
