In the invention, under a normal power connection state, the power connection rod 8 is abutted against the inner wall of the sliding groove 5, so that the connecting rod 4 is electrically connected with the power connection plate 9, and a stable power connection process is further completed, when the power connection rod is pulled for a short time by an external force, the inserted body 1 has a tendency of moving away from one side of the power connection plate 9 under the action of tensile force, so that the piezoelectric ceramic block 18 on the pull rod 3 drives the push plate 19 to move towards the baffle 14, and further the push plate 19 is impacted with non-Newtonian fluid in the inner bushing 2, and the tensile force is instantly completed by external pulling, so that the non-Newtonian fluid of the push plate 19 is rapidly collided, and due to the characteristic of the non-Newtonian fluid, the push plate 19 is subjected to extremely strong movement resistance, so that strong extrusion force is generated between the piezoelectric ceramic block 18 and the push plate 19, and further the piezoelectric ceramic block 18 generates higher voltage at the moment of external pulling, the electrorheological fluid is solidified and expanded, so that the expansion belt 13 is pushed by the electrorheological fluid to expand outwards, the connecting rod 4 is expanded towards the periphery, the connecting rod 4 cannot be directly drawn out after being inserted into the jack of the socket, the connecting rod 4 stays in the socket, the movement of the inserting body 1 is blocked by the solidified electrorheological fluid, the action of external instant tension is counteracted, the inserting body 1 cannot be driven to be separated from the socket, and the electric connection process is not influenced by pulling;

when the insert body 1 is pulled by external force, due to the existence of the buffer spring 6, external pulling force cannot directly act on the electric connection plate 9, so that the electric connection circuit is kept stable, and meanwhile, the buffer spring 6 can also prevent the connecting rod 4 from directly moving outwards to a certain extent, so that the electrorheological fluid can have enough time for solidification and expansion;

when the plug is required to be separated from the socket, the plug body 1 is slowly pulled outwards, and due to the fact that the pulling speed is slow, the non-Newtonian fluid cannot rapidly and powerfully collide with the push plate 19, the non-Newtonian fluid is enabled to pass through the through hole 15 and cross the baffle plate 14 under the pushing action of the push plate 19, meanwhile, the reaction force applied to the push plate 19 acts on the pull rod 3, the connecting rod 4 and the plug body 1, the plug body 1 and the connecting rod 4 are pulled out towards the outside of the socket, the connecting rod 4 is enabled to be separated from the electric connection plate 9, the partition plate 7 and the electric connection rod 8 slide towards the outside of the sliding groove 5 until the electric connection rod 8 abuts against the baffle ring 10, in this state, the electric connection rod 8 is not in contact with the connecting rod 4 any more, the partition plate 7 still abuts against the inner wall of the sliding groove 5, the electric connection circuit is enabled to be disconnected, the electric shock phenomenon cannot occur in the whole plug pulling process, therefore, the inserting body 1 drives the connecting rod 4 to move, the piezoelectric ceramic block 18 is not stressed and does not act on electrorheological fluid, the inserting body 1 can finally drive the connecting rod 4 and the electric connecting plate 9 to move after moving, the plug is smoothly pulled out, the reset spring 16 drives the pressure plate 17 to reset after being pulled out, and then the non-Newtonian fluid resets;

when the circuit that connects breaks down or leads to the circuit in the electric current increase because of other reasons, insert the inside temperature of body 1 and connecting rod 4 and will rise, and along with the rising of connecting rod 4 temperature, the inside dichloromethane solution of spout 5 will be heated gasification, thereby promote connecting rod 4 and remove, make the pole 8 that connects take place relative slip in spout 5 is inside, it offsets with fender ring 10 until the pole 8 that connects, and also will lead to the pole 8 that connects and connecting rod 4 separation this moment, make whole circuit break after the temperature risees, effectively avoid high temperature to lead to plug or circuit damage.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
