Working principle: when the electric connection plug 2 is inserted into the electric connection socket 1 in use, the matching sleeve 4 on the electric connection plug 2 is firstly directly inserted into the outer sleeve 3, the matching sleeve 4 is sleeved on the positioning cylinder 5, the matching sleeve 4 can rotate around the positioning cylinder 5, the electric connection plug 2 drives the matching sleeve 4 to rotate anticlockwise after the matching sleeve 4 is sleeved on the positioning cylinder 5, the matching sleeve 4 can drive the limiting plate 6 and the fixed seat 11 to rotate, when the limiting plate 6 rotates to contact with the poking plate 702 on the inner wall of the outer sleeve 3, the poking plate 702 can be driven to rotate upwards around the rotating point of the supporting rod 701, the first spring 703 is compressed, the limiting plate 6 can continue to rotate and finally is blocked from rotating anticlockwise by the second baffle 705, the poking plate 702 also returns to the initial position at the moment, the limiting plate 6 is positioned between the second baffle and the poking plate 702 at the moment through the rotation limitation of the first baffle 704, the limiting plate 6 is further enabled to rotate unidirectionally and limit the position of the limiting plate 6, the electric connection plug 2 is illustrated to rotate to the correct inserting position at the moment, then the electric connection plug 2 and the matching sleeve 4 can be driven to translate towards the inner sleeve 3, and finally, the electric connection plug 2 can be connected to the electric connection plug 2 can be accurately inserted into the electric connection socket 1, and the electric connection plug 1 can be connected to the electric connection plug 1, and the electric connection plug can be simply and the plug can be connected to the electric connection plug 1, and the plug can be connected to the electric connection plug 1.
When the pin 27 of the electrical connection plug 2 is inserted into the jack 25 of the electrical connection socket 1, at this time, when the matching sleeve 4 extends along the positioning barrel 5, the two inserting rods 8 inside the outer sleeve 3 gradually extend into the extending port 19 of the fixing seat 11 and enter the triggering cavity 12, after connection is completed, the two inserting rods 8 can abut against the two blocking blocks 1701 in the triggering cavity 12 and drive the two blocking blocks 1701 to move, after connection is completed, the inserting rods 8 can drive the blocking blocks 1701 to move away from the upper part of the fixing column 15, at this time, the fixing column 15 is not limited to move outwards under the action of the second spring 14 and extend out through the extending port 18, as shown in fig. 10 and 12, the fixing column 15 finally enters the fixing hole 10 of the fixing block 9 on the outer sleeve 3, and then the fixing seat 11 can be fixed through the matching of the fixing column 15 and the fixing block 9, and further limit fixing the matching sleeve 4 and the electrical connection plug 2 can be prevented from being separated from the electrical connection socket 1 due to pulling or external factors in the subsequent use.
When the matching sleeve 4 of the electric connection plug 2 stretches into the positioning cylinder 5, and the end part of the matching sleeve 4 gradually contacts with the elastic sealing ring 23 on the outer wall of the positioning cylinder 5 and extrudes the elastic sealing ring when the plugging and fixing are finished, the elastic sealing ring 23 moves along the outer wall of the positioning cylinder 5 in a direction away from the matching sleeve 4, meanwhile, the elastic sealing ring 23 drives the transmission rod 2402 and the connecting block 2403 to move, simultaneously compresses the fourth spring 2404, and tightly contacts with the matching sleeve 4 through the action of the fourth spring 2404 and the transmission rod 2402 on the elastic sealing ring 23, so that a gap between the matching sleeve 4 and the positioning cylinder 5 can be blocked through the elastic sealing ring 23, and the waterproof effect and the subsequent use protection effect of the connection of the internal pin 27 and the jack 25 are improved.
When the electrical connection plug 2 needs to be pulled out of the electrical connection socket 1, the operation handle 1603 can be pressed first to drive the moving rod 1602 and the linkage rod 1601 to move towards the inside of the matching cavity 13, and then the linkage rod 1601 drives the fixed column 15 to move towards the inner wall of the triggering cavity 12, so that the fixed column 15 gradually breaks away from the fixed hole 10 of the fixed block 9, finally the fixed column 15 completely enters the triggering cavity 12 and is positioned between the blocking block 1701 and the inner wall of the triggering cavity 12, then the fixed seat 11 is not limited and fixed any more, the electrical connection plug 2 can be pulled out towards the outer side far away from the electrical connection socket 1, after the blocking block 1701 is far away from the insertion rod 8, the blocking block 1701 is driven to restore the initial position and block the fixed column 15 due to the action of the third spring 1702, at this moment, the operation handle 1603 can be released, the matching sleeve 4 can slide outwards along the positioning cylinder 5 in the pulling process, and the limiting plate 6 can slide outwards between the second baffle 705 and the pulling plate 702, and the outward pulling out stability of the matching sleeve 4 can be ensured.
