The straight groove (42) of the plug sleeve is matched with the boss (21) of the plug locking component to limit the circumferential direction of the plug locking component (2). After the plug locking assembly (2) is assembled, the internal elastic part is in a pressed state, and two ends of the internal elastic part are tightly propped against the plug shell step (31) and the plug sleeve (4). The plug locking component (2) can be elastically deformed relative to the plug shell (3) along the direction of the axial far away from the plugging end in the plug or can rotate along the plug shell (3) under the drive of the plug sleeve (4).

In fig. 2, the socket housing (7) internally mounts the electrical contact insulating assembly (5); a rising spiral groove (72) is arranged on the thicker outer circular surface of the socket shell, and the initial and final circumferential included angle of the spiral groove (72) is less than 45 degrees; an open axial straight groove (73) is arranged above the spiral groove of the socket shell; a socket locking assembly (6) is sleeved on the thin outer circular surface of the socket shell (7), and the socket locking assembly axially extends out of the rectangular cantilever (61) and extends out of the straight groove (73) of the socket shell to the inside of the spiral groove (72) of the socket shell.
