A USB female terminal, comprising a shrapnel connected in sequence, a fixing part and a pin, the fixing part includes a first fixing part and a second fixing part, the two ends of the first fixing part are respectively connected to the shrapnel and the pin, and the two ends of the first fixing part There are card points protruding outward on both sides of the first fixing part for fixing the terminal on the female seat on the side. On the first fixing part and between the two card points near the end of the shrapnel, there is a concave on the front and a protruding on the back. support point.

Preferably, the second fixing portion is located on both sides of the pin.

Preferably, the second fixing portion is two outward protrusions on both sides of the pin.

Preferably, the end of the elastic piece is provided with an insertion portion for fixing the top end.

A USB receptacle comprises a metal shell, a plastic body and the USB receptacle terminal, the USB receptacle terminal is inserted into the metal case and fixed in the plastic main body.

Preferably, the plastic main body is provided with a terminal fixing part integrally formed with the plastic main body, the metal shell is located between the terminal fixing part and the plastic main body, both ends of the metal shell are open, and one end of the plastic main body is set as an opening, The metal shell is provided with a backstop structure, and the plastic main body is provided with a limiting structure corresponding to the backstop structure. The other end of the plastic main body opposite to the opening is connected with a terminal. The pins protrude from the back of the plastic body.

The beneficial effects of the present invention are:

1. On the first fixing part of the present invention and between the two clamping points, there is a support point with a concave front and a raised support point on the back, which can prevent the terminal from affecting the spring height of the spring when it is bent, and avoid causing inconsistent spring heights of the spring The phenomenon of instability improves the quality of the female seat.

2. The second fixing part can make the pins of the terminal be bent and clamped on the plastic main body.

3. The fixed feet and the metal shell are integrally formed, which not only reduces the assembly time and production cost, but also increases the stability of the connection between the metal shell, the fixed feet and the plastic body.

4. The combined structure of the terminal fixing part and the depressing tongue of the present invention prevents the head of the terminal from lifting, and the integrated design of the terminal fixing part, the depressing tongue and the plastic main body makes the quality more stable, and at the same time simplifies the manufacturing process and improves the production efficiency.
