When a downward force is applied to the force arm 410a from the outside, the force arm 410a may drive the magnetic driving unit 430b to rotate toward or away from the sealed switch tube 50, and a permanent magnet 436, such as a magnetic steel, is disposed in the magnetic driving unit 430 b. One end of the self-locking member 490 contacts with the base 340 of the conductive cartridge 30 and is provided with a stopping inclined surface 491, the inclination of the stopping inclined surface 491 gradually approaches the base 340 along the insertion direction of the plug 20, the other end of the self-locking member 490 is sleeved with a seventh elastic member 492, a limiting groove 493 is arranged on the self-locking member 490 and corresponds to the limiting groove 493, a stopping block 412a is arranged on the force arm 410a, and the stopping block 412a can be clamped into the limiting groove 493 or separated from the limiting groove 493.

During the process of inserting the plug 20 into the conductive chuck 30, the plug contacts the inclined stop surface 491 of the self-locking member 490 first, and the self-locking member 490 is pulled to separate from the base 340, the stop block 412a on the arm 410a is snapped into the limiting groove 493, the seventh elastic member 492a is compressed, and then the magnetic driving unit 430b is driven to rotate by manually pressing the arm 410 a.

When the magnetic driving unit 430b rotates toward the direction approaching the hermetic switch tube 50, the metal member 540 may be attracted to the stationary contact 521 under the action of the permanent magnet 436, such as magnetic steel, in the magnetic driving unit 430b, so as to complete the circuit connection. When the magnetic driving unit 430b rotates in a direction away from the hermetic switch tube 50, the metal member 540 loses the action of the external magnetic field, and is separated from the stationary contact 521 by the action of the fifth elastic member 550 disposed inside the switch tube 50, thereby achieving the disconnection of the circuit.

When the plug 20 is pulled out from the conductive collet 30, the self-locking member 490 is reset by the elastic force of the seventh elastic member 492a, the stop block 412a on the arm 410a is separated from the limiting groove 493, and at this time, the arm 410a cannot be manually pressed to close or open the closed switch tube 50.

Further, in order to prevent the plug 20 from being pulled out of the conductive chuck 30 when the switch tube 50 is in the closed state, which may cause the burning loss of the plug 20 and the conductive chuck 30 due to the generation of the arc between the plug 20 and the conductive chuck 30, the operating mechanism 40 further includes a limiting member 490a, the limiting member 490a is provided with a slot 491a matching with the arm 410a and corresponding to the slot 491a, the arm 410a is further provided with a poking rod 413a, the arm 410a may drive the limiting member 490a to move linearly through the poking rod 413a, the limiting member 490a is further provided with a limiting member 492a corresponding to the limiting member 492a, and the housing 210 of the plug 20 is provided with a card slot, when the plug 20 is inserted into the conductive chuck 30, the arm 410a is pressed to drive the switch tube 50 to be closed, and the poking rod 413a drives the limiting member 490a to move linearly, and the limiting member 492a is snapped into the card slot of the plug 20, so that the plug 20 cannot be pulled out of the socket 10, which may prevent the arc from being burned out of the plug 20 and the conductive chuck 30, thereby preventing the burning loss of the conductive chuck 20.

Similarly, when the plug 20 needs to be pulled out, the force arm 410a is manually pressed to disconnect the switch tube 50, an electric arc is generated inside the switch tube 50, meanwhile, the poke rod 413a drives the limiting piece 490a to move linearly, the limiting piece 492a slides out of the clamping groove of the plug 20, and then the plug 20 is pulled out. Namely: the switching tube 50 is turned on after the plug 20 is inserted and turned off before the plug 20 is pulled out, and an arc is generated in the switching tube and extinguished, thereby preventing the plug 20 and the conductive chuck from being burnt. In this embodiment, the movement of the magnetic driving unit 430b is realized by an external applied force, rather than by an insertion force of an external plug, the force arm 410a can be in a structure of applying an external force by pressing, rotating or pushing, and in this embodiment, the force arm 410a is in a pressing structure.
