the inner wall of the socket body 1 close to the cavity is fixedly connected with a fixing block 5, a plurality of triangular bags 7 are symmetrically arranged on two sides of the fixing block 5, magnetorheological fluid is filled in each triangular bag 7, the distance between every two adjacent triangular bags 7 on the same side is unequal, when the conducting strip 3 is inserted into the socket body 1, each triangular bag 7 can just abut against the triangular teeth 6, but the distance between every two adjacent triangular bags 7 is unequal, so that the conducting strip 3 can be ensured to always be in an abutting state with the triangular teeth 6 in any state; when the conducting strip 3 is at any position, the electromagnet 8 is electrified to generate a magnetic field, so that the triangular bag 7 can instantly abut against the triangular teeth 6, and the conducting strip 3 cannot be separated from the socket body 1.

Fixedly connected with electro-magnet 8 on the fixed block 5, the hollow drum 9 of inner wall fixedly connected with of jack is kept away from to socket ontology 1, and drum 9 internal seal sliding connection has piston 10, and piston 10 is close to one side fixedly connected with support 11 of fixed block 5, and support 11 runs through the upper wall of drum 9, and when conducting strip 3 inserted to socket ontology 1, can offset with support 11 to drive support 11 motion.

Two annular baffles 12 are fixedly arranged inside the cylinder 9, two first conductive blocks 14 and two second conductive blocks 15 are fixedly connected to the side wall of the cylinder 9, each first conductive block 14 and each second conductive block 15 are located between the two annular baffles 12, each annular baffle 12 is fixedly connected with a first spring 13, a plurality of first springs 13 are fixedly connected with a conductive plate 17 together, a large hole 18 and a small hole 19 are fixedly connected on the conductive plate 17, the aperture of the large hole 18 is larger than that of the small hole 19, a fixing frame 20 is fixedly connected to one side, far away from the piston 10, of the conductive plate 17, a second spring 16 is fixedly connected on the fixing frame 20, a circular sealing plate 22 is fixedly connected to one end, far away from the fixing frame 20, of the second spring 16, the diameter of the sealing plate 22 is larger than that of the large hole 18, and the sealing plate 22 is abutted to the large hole 18 through the third spring 21;

when the conducting plate 17 abuts against the first conducting block 14 and the second conducting block 15 at the same time, the electromagnet 8 is electrified to work to generate magnetic force, and then the property of the magnetorheological fluid is changed.

One end of the cylinder 9, which is far away from the support 11, is fixedly connected with a liquid bag 24, a side hole 23 is formed in the side wall of the cylinder 9, the side hole 23 is communicated with the cylinder 9 and the liquid bag 24, and the existence of the liquid bag 24 ensures that oil extruded from the cylinder 9 cannot leak to the outside.

The bracket 11 is made of an insulating material, and insulating oil such as mineral oil is filled in the liquid bag 24, so that the short circuit is avoided; the triangular teeth 6 and the triangular bags 7 are equal in size, so that the triangular teeth 6 and the triangular bags 7 can be just abutted, and when the triangular bags 7 feel a magnetic field and are hardened, the triangular bags 7 can be abutted against the triangular teeth 6, so that the triangular teeth 6 cannot move. The stiffness coefficient of the first spring 13 is greater than that of the second spring 16, and the stiffness coefficient of the second spring 16 is greater than that of the third spring 21, so that the components can operate normally when the piston 10 moves in the cylinder 9.

In the invention, in a stable state, the conductive plate 17 is positioned in the middle of the conductive blocks at the upper and lower sides, and the first conductive block 14 and the second conductive block 15 are in a relatively insulated state; since the liquid bag 24 and the cylinder 9 are filled with insulating liquid, when the piston 10 moves in the cylinder 9, the liquid in the cylinder 9 is squeezed by the piston 10 to move from one side of the conductive plate 17 to the other side, and since the aperture of the small hole 19 is small, the liquid on one side of the conductive plate 17 cannot move to the other side, the liquid will impact the conductive plate 17, and the conductive plate 17 will be driven to move.

When the piston 10 moves towards the direction close to the conductive plate 17, the conductive plate 17 is driven to move towards the direction far away from the piston 10, and the stiffness coefficient of the third spring 21 is smaller than that of the second spring 16, so that the third spring 21 can be compressed to enable the closing plate 22 to be separated from the conductive plate 17, the large hole 18 is communicated with two sides, oil on one side of the conductive plate 17 can rapidly circulate to the other side, the oil in the cylinder 9 is prevented from driving the conductive plate 17 to move violently, when the piston 10 moves towards the direction of the conductive plate 17, the conductive plate 17 is not contacted with the first conductive block 14 and the second conductive block 15 all the time, and in the process, the electromagnet 8 is always in a power-off state.

When the plug body 2 is inserted into the socket body 1, the triangular teeth 6 on the plug body 2 and the triangular bag 7 are extruded, and the triangular bag 7 is of a soft structure, so that the triangular bag 7 is not blocked; when the plug continues to be inserted and moves against the support 11, the two conducting strips 3 respectively contact with the reed 4 to supply power to external electric appliances, the plug continues to move to drive the piston 10 to move towards the conducting strip 17, the electromagnet 8 is always in a power-off state, and the plug can be rapidly inserted into the socket body 1.

When the plug body 2 is pulled rapidly by external force to make the conducting strip 3 quickly separate from the support 11, the first spring 13 elastically drives the piston 10 to quickly move towards the support 11, at this time, the closing plate 22 abuts against the large hole 18, so that liquid cannot flow through the large hole 18, and the oil can only move from one side of the conducting plate 17 to the other side through the small hole 19, so that the oil generates impact force on the conducting plate 17 to drive the conducting plate 17 to move towards the piston 10, when the conducting plate 17 is simultaneously contacted with the first conducting block 14 and the second conducting block 15, the two reeds 4, the first conducting block 14, the conducting plate 17, the second conducting block 15 and the electromagnet 8 form a loop, so that the electromagnet 8 is electrified to generate a magnetic field, when the magnetorheological fluid in the triangular bag 7 is subjected to the magnetic field, the magnetorheological fluid in the triangular bag 7 can generate extremely strong shearing yield hardness, namely the triangular bag 7 can not generate deformation due to the fixed property, and the, the conducting strip 3 can not be drawn out of the socket body 1, so that the situation that the plug is separated from the socket due to the fact that the plug is pulled violently by the outside is avoided;

normally when outwards extracting plug body 2, electro-magnet 8 is in the outage state, and triangular bag 7 does not produce the effect of blockking to triangular tooth 6 this moment, and artifical speed of normally pulling out the plug is lower, and the velocity of motion of piston 10 is lower promptly, and the unable drive current conducting plate 17 of current conducting plate 17 department liquid flow velocity moves to contacting with first conducting block 14 and second conducting block 15, so in this device, the user of service can normally insert and extract the plug.

When the outside generates violent vibration, the sealing plate 22 synchronously vibrates to be separated from the contact with the conducting plate 17, so that a certain amount of bidirectional circulating oil can be arranged at the position of the large hole 18, the conducting plate 17 also moves up and down along with the vibration of the outside in the process and is in contact with the first conducting block 14 and the second conducting block 15, the electromagnet 8 is electrified to generate a magnetic field, magnetorheological fluid in the triangular bag 7 generates extremely strong shearing yield hardness under the magnetic field environment, the plug cannot be separated from the socket under the vibration of the outside, and the condition that the electric appliance is powered off easily can not be generated when the electric appliance works.
