The circular slide bar (53) moves into the connector body (3) and contacts the detection switch (54). The alarm (55) stops sounding by squeezing the detection switch (54), thereby preventing a short circuit of the device due to a failed docking and affecting the normal use of the device. Step 4: The push plate (52) moves toward the middle of the connector body (3), the triangular plate (57) contacts the triangular protrusion (59), and the sliding plate (58) is pushed downward by the triangular plate (57), so that the sliding plate (58) clamps the sealing ring (510) to prevent the socket (2) from being separated from the connector body (3) and causing a short circuit in the equipment, thereby creating a safety hazard.
