In this docking state, each plug connection terminal 23 of the plug connector 20 is in contact with the corresponding socket connection terminal 14 to realize signal transmission. The contact portion 222 of the plug power supply terminal 22 is in contact with the pair of first elastic arms 126 and the pair of second elastic arms 127 of the socket power supply terminal 12 to realize current conduction. Since the contact portion 222 of the plug power supply terminal 22 and the socket power supply terminal 12 form a multi-point contact (4-point contact), the contact area of the electrical conduction between the plug power supply terminal 22 and the socket power supply terminal 12 is effectively improved, and the current flows through the plug power supply terminal 12. When 22 is in contact with the socket power supply terminal 12, due to the multi-point contact, it has a certain shunt effect on the current, which can greatly reduce the contact resistance between the plug power supply terminal 22 and the socket power supply terminal 12, and can also greatly reduce the temperature rise during use. , thereby improving the flow capacity of the socket connector 10 and the plug connector 20 in the docking state. In addition, the plug power supply terminal 22 is clamped and contacted by a pair of first elastic arms 126 and a pair of second elastic arms 127, so that the connection between the socket connector 10 and the plug connector 20 is more stable, effectively preventing the contact failure caused by Electronic equipment malfunctions, and therefore, reliability is improved.
