As shown in fig. 2 and 4, the electromagnetic trip assembly 4 includes a pressing rod 401 disposed on one side of the connection column 102, a blocking rod 402 rotatably connected to the disconnecting switch, and an electromagnetic trip 403 for controlling the movement of the blocking rod 402, wherein the pressing rod 401 is provided with a stopper 404 corresponding to the blocking rod 402, one side of the stopper 404 corresponding to the blocking rod 402 is an inclined structure, and the pressing rod 401 and the connection column 102 are an integrated structure.
The electromagnetic release 4 is one of releases, only provides magnetic protection, namely short circuit protection, and actually is a magnetic return force, and when the current is large enough, the generated magnetic force overcomes a counter spring to attract an armature to strike a traction rod so as to drive a mechanism to act and cut off a circuit.
When the pressing rod 401 pushes the connecting column 102 to move, the acting force of the tension spring is overcome, and the stopper 404 can pass over the stop rod 402 by continuously pushing; in the process, because the corresponding sides of the stop 404 and the stop lever 402 are both inclined structures, the movement of the stop 404 is not obstructed, and when the connecting column 102 is loosened, the stop lever 402 blocks the movement of the stop 404, so that the position of the connecting column 102 is fixed. When the two electromagnetic tripping assemblies 4 are controlled to move, the first connector 103 can be moved to the position embedded with the second connector 201, and the normal power-on between the overcurrent trip assembly 1 and the immersion-proof trip assembly 2 is further realized.

The working principle of the anti-flooding circuit breaking component 2 is basically the same as that of the overcurrent circuit breaking component 1, and the only difference is that the electromagnetic tripping component 4 for controlling the action of the anti-flooding circuit breaking component 2 is controlled by a controller, namely when the water level sensor detects that the water level reaches a threshold value, the action of the electromagnetic tripping device 404 is directly controlled, so that the disconnection of a circuit is realized.

Because one side of the two isolating blocks 302 which is arranged oppositely is of an inclined structure, when the connecting column 102 moves, the isolating blocks 302 can be pressed, so that the influence on the normal embedding between the first connector 103 and the second connector 201 can be avoided, when in use, the first connector 103 and the second connector 201 can be separated from each other when the overcurrent circuit-breaking component 1 acts or the immersion-proof circuit-breaking component 2 acts, when in separation, the first connector 103 or the second connector 201 is not supported, so that the isolating blocks 302 can reset under the action of a tension spring, the immersion-proof circuit-breaking component 2 and the overcurrent circuit-breaking component 1 can be thoroughly isolated, the electric arc can be prevented from existing when the short circuit occurs in a humid environment, and the problem that the short circuit damage of equipment is caused by electric leakage in the isolating switch when water enters the isolating switch can be effectively avoided, the practicability is stronger.
The distance between the two isolation blocks 302 is greater than the depth of the connecting groove 104, so that the problem that the isolation blocks 302 cannot reset under the action force of the tension spring due to too close distance can be avoided when the first connecting head 103 is separated from the second connecting head 201, and the practicability is higher.
The bottom of the connecting cavity 301 is provided with an isolation groove 303 corresponding to the isolation block 302, and a sealing rubber pad is arranged at the bottom of the isolation groove 303, so that the isolation block 302 can be embedded into the isolation groove 303 after the isolation block 302 is reset, and the isolation effect can be effectively improved through the sealing rubber pad.
