When one end of the switch 203 is stuck on the wire connector 2022, The springs A2023 on both sides will respectively squeeze the wire connectors 2022 on both sides toward the middle, so that the switch 203 and the wire connectors 2022 are more tightly engaged. At the same time, the inner end surface of the wire connectors 2022 is arc-shaped and concave. It is beneficial for the wire connector 2022 to be stuck more tightly.

The switch 203 includes a T-shaped slider 2031 that is slidably installed on the top surface of the bearing plate 201 and an electromagnet 2032 that is fixedly installed on the upper end of the outer side of the T-shaped slider 2031.

In the inner cavity, at this time, the long rack 101 will drive the switch 203 to slide as a whole through the magnetic top post 2034, until the connecting frame 2035 is clamped on the wire connector 2022 on the other side, so that the spare monitoring electronic monitoring components are After the line passes, the line will continue to be monitored to ensure the continuity of monitoring.

When the monitoring components in the online monitoring device are damaged, the central controller 9 starts the transmission assembly 7 to drive the sliding assembly 10 to slide on the bottom surface of the inner cavity of the protective shell 1. At the same time, the central controller 9 cuts off the power of the electromagnet 2032, so that the magnetic The top post 2034 stretches out under the elastic force of the built-in spring and is stuck on the side wall of the sliding assembly 10. The sliding assembly 10 will drive the switch 203 as a whole to slide on the bearing plate 201 to the other side by carrying the magnetic top post 2034.
