After squeezing with force, the buckle ring (73) passes through the limiting ring (24), and the positioning portion B (71) is positioned inside the extension tube B (21), so that the female contact piece (7) can be positioned and fixed; S4, then the male insulating shell (1) is inserted into the interior of the female insulating shell (2), so that the internal conductive column (51) is inserted into the interior of the conductive slot (72) to form an electrical connection, and the connecting column (13) is inserted into the interior of the L-shaped slot (23), and at the same time, the extrusion ring (61) on the end surface is extruded, and the multiple elastic blocks (62) on the side wall of the extrusion ring (61) are extruded, and at the same time, the sliding rod (63) is driven to squeeze the installation ring (64) on the end surface, so that the bent spring sheet (65) is away from the positioning ring (12), and under the mutual elastic action of the elastic block (62) and the bent spring sheet (65), the stress component (6) can stably reinforce and seal the connection; S5, then rotating the male insulating shell (1) so that the connecting column (13) is engaged and connected to the L-shaped slot (23), and the connecting slot (14) on the connecting column (13) is connected to the protrusion (82) on the card frame (81), thereby achieving position fixing; S6. Finally, the protective shell (3) is threadedly rotated on the outer wall of the threaded ring (22) to further protect and reinforce the connection.
