The four GND terminals A1, A12, B1 and B12 are in elastic contact with the housing 101. By using four GND (A1, A12, B1, B12) terminals to contact the metal housing 101, there is another performance. When the female socket tongue is in contact with the elastic terminal, the four GND terminals The D terminal is close to the contact point of the shell 101, and the terminal bend is pressed down to make the shell 101 better grounded. The grounding solution can also be used for other TYPE-C plugs because of its simple structure and low manufacturing cost. The first elastic terminal 104 and the second elastic terminal 105 (A1 / A12 / B1 / B12) are provided with a bend 3, and the bend 3 is elastically in contact with the inner wall of the shell 101. A bend 3 is set through the GND terminal to contact the metal shell 101, so that better contact and conduction are achieved when the female socket tongue is inserted.
