Under the elastic force of the spring latch itself, the pin rod of the spring latch matches and plugs into the locking socket, and the protective cover can be assembled, which is convenient for assembling the protective cover.

[0020] 4. This kind of intelligent sensing terminal for electricity metering based on Internet of Things technology, when the electricity thief removes the original wiring, due to the trigger circuit being turned on, the microprocessor controls the first electric push rod to work, and the output shaft of the first electric push rod drives the positioning cone plate to move, so that the positioning cone plate is separated from the positioning block.
