The application also provides a communication plug anti-loosening method, which comprises the following specific steps: step S1, providing the communication plug with looseness prevention, aligning the rectangular plug 1 to the rectangular socket 2; step S2, the rectangular plug 1 is inserted into the rectangular socket 2 with a force, and the force is continuously applied to make the rectangular plug 1 enter the bottom of the rectangular socket 2, during the continuous insertion process, the second magnet 23 indirectly contacts the second magnet 26, and the second magnet 26 and the sealing block 25 are gradually driven to move towards the accommodating groove 24 close to the tip of the ratchet (even if a certain deviation occurs due to the action of the second spring 30, the first magnet and the second magnet can still move along the lower side wall of the ratchet due to the attraction between the first magnet and the second magnet), so as to squeeze out the liquid conductive liquid in the accommodating groove 24, such as the metal conductive liquid or other highly conductive liquid, and sequentially squeeze the flexible conductive film 20 through the conductive liquid groove, the communication channel 21 and the elastic groove, when the sealing block 25 contacts or approaches the fourth magnet 28, due to the adsorption force between the third magnet 27 and the fourth magnet 28, the sealing block can be kept at the upper end part (close to the tip end side of the ratchet) of the accommodating groove 24, so that the contact between the contact pin 15 and the needle groove 16 is realized step by step in the extrusion process, the contact is continuously and completely carried out on the contact pin 15 entering the needle groove 16 when the last ratchet is continued, good alignment can be realized due to the gradual extrusion and gradual sealing, and the insertion can be well realized due to the gradual increase of the resistance force, and the conductive film 20 can be always extruded and kept in contact after the insertion due to the adsorption effect of the third magnet 27 and the fourth magnet 28; step S3, sliding the moving key 19 to gradually pull the rectangular plug 1 out of the rectangular socket 2, during the pulling process, the ratchet block 9 is located between the (n-1) th and the (n) th ratchets, for example, as shown in fig. 3, 7 and 8 of the present application, the ratchet block 9 is located between the (3) th and the (4) th ratchets, as shown in fig. 10, since the movement of the ratchets during the pulling process will cause the end of the ratchet 9 to be able to approach the lower end side of the (n) (e.g., 4) th ratchets, so that due to the cooperation of the first magnet 23 and the second magnet 26, although during the pulling process, the end of the ratchet 9 may not well contact the lower end side of the (n) th ratchets, due to the ratchet elasticity of the second spring 30, the attraction force of the first magnet 23 and the second magnet 26 is engaged, it still enables the first magnet 26 to move on the lower end side of the (n), so that the sealing block can compress the conductive liquid in the accommodating groove 24 again, however, as the pressing proceeds, the inner space of the whole conductive liquid groove, the communication channel 21 and the elastic groove 22 is basically limited, the volume of the inner space is not changed basically, the pressing proceeds, the pressure on the back is increased, so that the pressure on the sealing block 25 in the 1 st to the n-1 st ratchets is increased, the increased pressure can overcome the adsorption force between the third magnet 27 and the fourth magnet 28 in the 1 st to the n-1 st ratchets, namely, the pressure generated by the conductive liquid in the inner part is larger than the adsorption force between the third magnet 27 and the fourth magnet 28 in the 1 st to the n-1 st ratchets, so that the pressing on the conductive film 20 is released, the tip of the contact pin 15 can be pulled out, and the sealing block 25 in the 1 st to the n-1 st ratchets can be restored to the accommodating groove 24 due to the pressure restoration to the initial pressure The bottom, although the pulling-out needs a certain force at the beginning, it also ensures the safety, for example, it can prevent the pulling-out of children (the force of children is not enough), after the ratchet block 9 leaves the nth ratchet, the sealing block 25 in the nth ratchet can be reset to the bottom again due to the restoring force of the first spring 29, so as to repeat the operation next time. Therefore, through the matching action of the flexible conductive film, the communication channel, the elastic groove, the first magnet, the containing groove, the sealing block, the second magnet, the third magnet, the fourth magnet, the first spring and the second spring, the tip of the contact pin can have a reduced diameter before the contact pin is inserted into the needle groove, so that the insertion can be realized quickly, meanwhile, in the inserting process, the first magnet continuously drives the second magnet to move in the containing groove to extrude the conductive liquid in the containing groove, so that the conductive liquid is extruded and enters the elastic groove through the conductive liquid groove and the communication channel, the flexible conductive film is gradually extruded, the contact pin can be in complete and sealed contact with the needle groove, the influence of external moisture on the contact is prevented, meanwhile, the full contact between the needle groove and the periphery of the contact pin is realized, and the poor contact caused by the relatively large needle groove relative to the contact pin is prevented, and simultaneously, the heat dissipation effect is improved.
