The working principle of the invention is as follows: firstly, the sleeve body 1 is close to the fixed socket housing 5, the press ring 20, the long press plate 24 and the short press plate 25 of the vacuum sealing structure 7 are aligned with the interface 26 of the fixed socket housing 5, then the sleeve body 1 is rotated, the long press plate 24 and the short press plate 25 enter the through hole 27, namely the dotted line position shown in the position C shown in figure 7, the first seal ring 38 and the second seal ring 39 are just positioned between the gap between the sleeve body 1 and the fixed socket housing 5, then the connecting sleeve 9 is rotated to enable the connecting sleeve 9 to move towards the fixed socket housing 5, the sleeve body 1 and the fixed socket housing 5 are fixed, the connecting sleeve 9 and the fixed socket housing 5 are continuously screwed while vacuumizing the sleeve body 1 and the fixed socket housing 5 by using an external vacuum pump, the sleeve body 1 and the fixed socket housing 5 are sealed by the continuous pressure applied to the press ring 20 by the external atmospheric pressure, when the action of the external air pressure on the compression ring 20 is weakened, the elastic force of the second spring 23 keeps the compression force, so that the cavities of the sleeve body 1 and the fixed socket shell 5 are kept in a vacuum state continuously, finally, the connecting sleeve 9 is rotated continuously, the threads of the connecting sleeve 9 drive the sliding socket shell 6 to slide towards the direction of the sleeve body 1, then the choke plug 30 is driven into the choke plug hole 28, and the vacuum sealing structure 7 is further sealed and compressed by the fastening action of the sliding socket shell 6 and the connecting sleeve 9;
when the sleeve body 1 approaches the fixed socket shell 5, the elastic plug mechanism 4 is inserted into the socket 8, firstly, the elastic arm 14 contacts the socket 8, the elastic arm 14 interferes with the socket 8, so that the plug 12 is subjected to resistance, the plug 12 drives the plug seat 11 to slide on the inner wall of the sleeve body 1, and further the first spring 13 generates slight compression, the compression amount does not cause the indoor optical cable 2 to be compressed and bent until the sleeve body 1 drives the elastic arm 14 to continue to move towards the socket 8, the interference with the socket 8 disappears, the first spring 13 instantly releases the elastic force, the plug 12 is instantly plugged with the socket 8 under the action of the elastic force, the situation that the plugging is not real is avoided, the connecting sleeve 9 is connected with the fixed socket shell 5 through threads, the plugging effect is further fastened, and the situation that the plug 8 and the plug 12 are loosened after long-time use is avoided.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
