Meanwhile, the upper ends of the contact I11, the contact III and the contact IV 14 respectively deviate from the contact II 12 and are provided with a bending sheet I111, a bending sheet III 131 and a bending sheet IV 141, and the upper end of the contact II 12 is provided with a bending sheet II 121 along the direction of the contact II. And, bending piece one 111, bending piece two 121, bending piece three 131 and bending piece four 141 are buckled to same direction, and simultaneously, bending piece two 121's upper end has also been buckled to the opposite direction that bending piece two 121 self was buckled, and the department of buckling becomes the cambered surface form. In this way, the arc surface contacts with the corresponding pole on the contact pin, so that the abrasion of the second bending piece 121 to the contact pin in the inserting and pulling process can be reduced. In addition, the four bending pieces have a height difference from each other, and the bending piece two 121, the bending piece three 131, the bending piece one 111 and the bending piece four 141 are sequentially arranged from top to bottom. Therefore, each bending piece can be contacted with different electrodes on the contact pin in a one-to-one correspondence manner.

Meanwhile, the first bending sheet 111 and the third bending sheet 131 are provided with the first protrusions 1111 on opposite surfaces, so that the first bending sheet 111 and the third bending sheet 131 can be conducted with corresponding electrodes on the pins only through the first protrusions 1111, and the problem that the first bending sheet 111 and the third bending sheet 131 are conducted with a plurality of electrodes simultaneously is avoided. Moreover, the two protrusions 1111 are arranged oppositely to clamp the contact pin, so that the contact pin and the earphone socket can be firmly fixed.
