[0039] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0040] like Figures 1 to 6 As shown, the embodiment of the utility model provides a high-transmission-rate precision Type-C connector, including a Type-C interface 1, a circuit board 2, an insulating shell 3, a conductive terminal 4 and a terminal clamp 5; the insulating shell 3 has an accommodating space 30 inside, the front end of the insulating shell 3 is provided with a side groove 31 connected to the accommodating space 30, the accommodating space 30 is provided with a first positioning pin 32, the Type-C interface 1 includes a plug-in portion 11 and a tongue portion 12, the plug-in portion 11 is used to be plugged and connected with the Type-C female socket, and the tongue portion 12 extends The Type-C interface 1 is inserted into the side groove 31 and movably connected with the first positioning pin 32, so that the Type-C interface 1 can be horizontally rotated around the first positioning pin 32 and along the side groove 31; the Type-C interface 1 can be plugged and connected with the Type-C female socket to realize data transmission and charging functions.

[0041] like Figures 1 to 3 As shown, the tongue plate portion 12 is provided with a first positioning hole 121 movably connected to the first positioning pin 32, the outside of the first positioning hole 121 is provided with a plurality of concentrically arranged conductive rings 122, the terminal clamp seat 5 is arranged in the accommodating space 30, the conductive terminal 4 is passed through the terminal clamp seat 5, the terminal clamp seat 5 is used to clamp the conductive terminal 4, the circuit board 2 is arranged on the side of the accommodating space 30 away from the first positioning pin 32, one end of the conductive terminal 4 is in contact with the surface of the conductive ring 122, and the other end of the conductive terminal 4 is connected to the circuit board 2. The conductive ring 122 can be used to transmit data or current signals. When adjusting the rotation angle of the Type-C interface 1, the conductive ring 122 can always maintain contact with the conductive terminal 4 to ensure the reliability of data or current signal transmission, avoid bending and squeezing between the traditional Type-C interface 1 and the data line to cause damage to the line, so that the signal transmission will not be interrupted or interfered, the signal transmission rate is high, and the connection stability is high; and the terminal clamp 5 can clamp and fix the conductive terminal 4 to avoid the conductive ring 122 of the tongue plate portion 12 causing the conductive terminal 4 to deviate during the rotational friction with the conductive terminal 4.
