[0025] Example: See Figure 1-9 The utility model provides a technical solution: a multi-locking connector. The application is mainly aimed at improving the problem that when the pin and the socket are matched during the use of the existing connector, the pin is easily restricted by the socket, and the gap between the pin and the socket wall is too large, the two inner conductors of the connector cannot be in close contact, the contact resistance becomes large, and the electrical performance index of the connector is very poor, which affects the use of the connector. The specific scheme is as follows: It includes a connector 1, a socket 2 and a pin 3. The connector 1 and the socket 2 are respectively provided with sockets corresponding to the wires, and the sockets are arranged side by side. The connector 1 is plugged into the socket 2.

In the initial state, the angle between the V-angle lap 1 51 and the V-angle lap 2 54 is the largest.
[0027] See also Figure 6 and Figure 7, wherein a spring sheet 52 is provided inside the clamping member 5, the pin 3 contacts the spring sheet 52, and the pin 3 is provided between the spring sheet 52 and the limiting protrusion 53. A limiting protrusion 53 is provided at the protrusion of the clamping member 5 corresponding to the spring sheet 52. The limiting protrusion 53 is provided at the protrusion of the spring sheet 52, and the position of the pin 3 can be limited by the limitation of the spring sheet 52 and the limiting protrusion 53, so as to effectively avoid the pin being limited by the socket, and the gap between the pin and the socket wall being too large, so that the two inner conductors of the connector cannot be in close contact, the contact resistance becomes large, and the electrical performance index of the connector is very poor, which affects the use of the connector, thereby improving the stability of the connector.
[0028] See also Figure 3 and Fig. 9 A limiting groove 31 is provided on the pin 3, and the limiting protrusion 53 is clamped inside the limiting groove 31.
