A clamping spring 24 is welded to the side wall of one end close to the connection post 3. The coil 19 is welded to the inner wall of the clamping cavity 18. The end of the clamping cavity 18 close to the connection post 3 is slidably connected with a conductive rod 20, which conducts electricity. The rod 20 is glued to the inner wall of the socket 2 .

The inner wall of the connecting groove 31 is sealed and slidably connected with two limit rods 32. The ends of the two limit rods 32 close to each other are in the shape of a lock tongue. The two limit rods 32 are jointly welded with a return spring 33. The side walls of 3 are provided with limit holes 7, and the two limit rods 32 are respectively slidably connected with the inner walls of the two limit holes 7; one end of the power receiving column 3 close to the clamping cavity 18 is provided with a plurality of clamping holes 25 and 7. In the conductive groove 26 , the plurality of clamping rods 22 are respectively abutted against the inner walls of the plurality of clamping holes 25 , and the conductive rods 20 are abutted against the inner wall of the conductive groove 26 .

When connecting the connector, firstly, the two sockets 3 on the plug 1 are roughly corresponding to the positions of the two sockets 34 on the socket 2, and then the sockets 3 are inserted into the sockets 34. , in the actual insertion process, the magnetic force generated by the guide block 6 acts on the positioning block 4 on the plug 1, so that when the plug 1 is close to the socket 2, the positioning block 4 will approach the guide block 6 under the action of the magnetic force, and then It makes the two poles 3 automatically positioned, which is convenient for the insertion of poles 3, and is convenient for use in the environment with poor light. After the poles 3 are inserted into the socket 2, the pole 10 will move in During the process, it gradually enters the power receiving hole 8. After the power receiving column 3 is completely inserted into the socket 2, the conductive groove 26 on the power receiving column 3 will be in contact with the conductive rod 20, which will play a certain role as a reminder to avoid excessive Insertion leads to damage to the contact post 3 .

After the power receiving post 3 is inserted into the socket 2, the power receiving plate 16 on the socket 2 can be pushed, so that the power receiving plate 16 drives the two trigger rods 17 to move toward the inside of the contact block 11, thereby making the two inner parts of the contact block 11 move. Under the action of the magnetic force of the trigger rod 17, the two permanent magnets move opposite to each other, thereby causing the contact block 11 to expand, so that the contact block 11 is in close contact with the inner wall of the power receiving hole 8 after the expansion, so that the power receiving column 3 is electrified, In this way, the signal transmission of the connector is realized. During the movement of the power receiving board 16, the power receiving board 16 continuously squeezes the limit spring 15, so that the limit spring 15 is connected to the power board 16 by a certain thrust, and the power board 16 During the moving process, the side wall of the power receiving plate 16 will push the limiting plate 14 to overcome the elastic force of the torsion spring, thereby making the limiting plate 14 rotate into the limiting slot 13, thereby realizing that the power connecting plate 16 completely pushes the trigger rod 17 into the position. , when the power receiving plate 16 moves to the bottom, it will no longer be in contact with the limit plate 14, so that the limit plate 14 returns to its original position under the action of the torsion spring, and then the power receiving plate 16 is released. Under the action of the elastic force of 15, the power receiving plate 16 will abut against the limit plate 14, so that the position of the power receiving plate 16 is limited, so that the trigger rod 17 can maintain the relative position, and the stable connection between the contact block 11 and the power receiving column 3 is realized. , to achieve effective signal transmission.

During the insertion process of the power receiving post 3, the power receiving post 3 is in contact with and abutting against the two reeds 28. After the power receiving post 3 is energized, the reeds 28 will be energized, so that the push rod 29 will be energized to start, so that the push rod will be energized. 29 drives the push plate 30 to move, so that the hydraulic oil in the limit box 27 moves to the inside of the connecting groove 31, and then pushes the two limit rods 32 to overcome the elastic force of the return spring 33 to move into the limit hole 7, thereby making the two limit rods 32 move toward the limit hole 7. The position rod 32 limits the two connection posts 3, so that the connection post 3 cannot be pulled out, which avoids the separation of the connection plug 1 and the connection socket 2, and ensures the stability of transmission. The rod 20 will transmit current to the coil 19, so that the coil 19 is energized to generate a magnetic field, so that the plurality of clamping rods 22 overcome the elastic force of the clamping spring 24 under the action of the magnetic force, and move into the corresponding clamping hole 25, thereby The purpose of clamping and limiting the connection post 3 by a plurality of clamping rods 22 is realized, so that the connection post 3 will not easily shake due to external vibration, and the occurrence of poor contact caused by the shaking of the connection post is avoided. .

When the connector plug 1 needs to be pulled out, firstly, the two limit plates 14 are rotated toward the inside of the limit slot 13 so that they no longer have a limiting effect on the electrical plate 16 , so that the electrical plate 16 is placed in the limit spring 15 . Under the action of the elastic force, the trigger rod 17 can be driven away from the interior of the contact block 11, so that the two permanent magnets on the inner wall of the contact block 11, under the mutual attractive force, approach each other, so that the contact block 11 shrinks, and is no longer connected to the electrical hole. 8 offset, so that the power connection post 3 is powered off, and then the push rod 29 is powered off and reset, so that the two limit rods 32 are moved out of the limit hole 7 under the elastic force of the reset spring 33, so that they no longer connect to the power post. After the coil 19 is powered off, the magnetic field will no longer be generated, so that each clamping rod 22 is separated from the clamping hole 25 under the action of the clamping spring 24. At this time, the connection post 3 can be easily pulled out of the connection socket. 2. Since the power connection column 3 has been powered off, the occurrence of accidental electric shock due to leakage can be effectively avoided.
