The structure of the utility model is reasonable, the design is novel, and the practicability is strong. After the multiple elastic claws of the crown spring are in plug-in contact with the male end, good stability and insertion and extraction force are formed. The main body and the pin tube, both made of copper, can stably transmit current and signals through the interference fit between the main body and the pin tube. The pin shaft made of insulating plastic material plays the functions of insulation and compressibility. The stability of the contact between the pin shaft and the pin tube is increased through the inclined plane structure.
