The positioning pin 46 is provided on the back of the fixing member 4 to provide a precise positioning function. The positioning pin 46 can be used in conjunction with the corresponding positioning hole or groove to ensure that the fixing member 4 is installed in the correct position to avoid offset or misalignment. This design helps to maintain the accurate alignment of the connector and ensure the accuracy and stability of the connection. The design of the insertion boss 45 and the insertion groove 1332 makes the assembly of the connector more convenient and efficient. Through simple insertion and matching operations, the fixing member 4 can be quickly and accurately installed in the plastic shell 1, thereby improving assembly efficiency and reducing assembly costs.
