This application provides a connector female socket, a connector male head, and a connector. The connector female socket includes a housing and a spring contact. The spring contact adopts an inverted U-shaped main body design, with a flexible contact structure housed within a symmetrically arranged clearance groove in the middle: including a first flexible contact extending obliquely from the top and second flexible contact parts symmetrically distributed on both sides. After the male head is inserted, three stable contact points are formed in a triangular distribution: firstly, the three-point contact design makes the current distribution more uniform, which can reduce contact resistance; secondly, the progressive contact method ensures both low insertion and extraction force and maintains sufficient contact pressure; thirdly, the triangular contact layout significantly improves vibration resistance and effectively suppresses fretting wear; finally, the interference fit fixing method of the spring contact results in a long product insertion and extraction life. This design is suitable for high-current applications in new energy vehicles, ensuring high reliability while also taking into account ease of assembly.
