A limit groove 12 is provided inside the female connector 1. The positioning slot 11 can be used to fix the secondary connecting rod 10. This provides further positioning and fixing, which helps to keep the secondary connecting rod 10 stable during high current transmission, preventing it from rotating or shifting, thereby ensuring the reliability and safety of the electrical connection. By setting the main connecting rod 9 to be inserted into the first connecting hole 7 and the secondary connecting rod 10 to be inserted into the second connecting hole 8, this insertion method enables the female end 1 of the electrical connector to achieve a reliable electrical connection during high current transmission, which helps to evenly distribute the current load, reduce the risk of local overheating, and ensure the stability of the connection, preventing the connecting rod from loosening or falling off during use.

[0027] The number of limit blocks 3 is set to two, and the two limit blocks 3 are symmetrically distributed on the left and right sides with the connector female end 1 as the center.
