When the electrical connection plug 1 and the electrical connection socket 2 need to be separated, the connection ring 33 can be rotated to move away from the outer sleeve 4, the connection ring 33 can drive the mounting ring 9 and the trigger rod 10 to move, at this time, the trigger rod 10 can gradually move away from the movable column 12 and the socket 15, at this time, the second spring 14 drives the special-shaped block 13 to gradually restore to the initial position, at this time, the transmission rod 803 and the first matching block 802 can return to the initial position through the first spring 801, that is, the transmission rod 803 can drive the piston plate 804 to move back to the initial state in a direction away from the airbag ring 7, at this time, the airbag ring 7 does not expand to fit the outer wall of the base 27, at the same time, the second matching block 17 and the moving rod 18 can also return to the initial position through the action of the third spring 16, that is, the moving rod 18 can drive the limiting plate 19 to move towards a direction close to the outer wall of the insertion tube 3, and finally returns to the initial state, and is not limited by the blocking ring plate 20, at this time, the insertion tube 3 can be moved out from the outer sleeve 4, and the disassembly can be completed, and is simple and convenient.

When water enters the part between the outer sleeve 4 and the insertion cylinder 3 in use, the water flows into the water falling cavity 21 from the water falling hole 22 on the inner wall of the outer sleeve 4 and finally flows out to the outside in a single direction through the water outlet 23, so that the use of the electric connector is prevented from being influenced. When the electrical connection plug 1 and the electrical connection socket 2 are immersed in water or submerged in heavy rain, water ingress into the interior of the electrical connector may be a serious threat to circuit failure and may cause problems with other circuits being mated. At this time, the amount of water entering the water falling cavity 21 is larger and larger, when the amount of water in the water falling cavity 21 is larger than the amount of water discharged from the water outlet 23, at this time, the water in the water falling cavity 21 drives the stress plate 25 to move along the partition plate 24 and compress the fourth spring 26, the stress plate 25 extrudes the gas in the gas storage cavity into the connecting channel 29, the gas in the connecting channel 29 enters the triggering groove 28 again, so that the elastic membrane 31 is extruded, the elastic membrane 31 is deformed, when the elastic membrane is deformed to a certain extent, the puncturing rod 32 contacts the pre-breaking layer 30 and punctures the pre-breaking layer 30, at this time, the polyurethane caulking agent in the elastic membrane 31 overflows, the polyurethane caulking agent fills the gap between the insertion cylinder 3 and the base 27, at this time, the gap is filled, water can be further effectively prevented from entering, and the safety of the circuit and the use can be ensured.
