[0030] Specifically, as Figure 1-2 shown, by installing the plugging mechanism 2 on the meter body 1, through the detachable connection design, the installation and maintenance process of the electric energy meter is simplified. When a fault occurs and replacement is needed, only the faulty component such as the plugging mechanism 2 needs to be replaced; through the connection detection module 4, the connection state of the electric energy meter is detected and fed back in real time, enabling the user to clearly know the working state of the device, master the real-time working state of the electric energy meter, and facilitate quick identification and solution of problems.

[0031] Furthermore, the plugging mechanism 2 includes: a support base 21, a plurality of wires, a plurality of conductive columns 22 corresponding to the plurality of wires one by one, and a plurality of insulating columns 23 corresponding to the plurality of conductive columns 22 one by one for increasing insulation; the support base 21 is detachably connected to the meter body 1; a receiving cavity 7 is arranged in the support base 21; the insulating columns 23 are detachably connected to the support base 21 and are located in the receiving cavity 7; the conductive columns 22 are detachably connected to the insulating columns 23 and are located inside the insulating columns 23; the wires pass through the outside of the support base 21 and are electrically connected to one end of the conductive columns 22; the other ends of the conductive columns 22 are respectively electrically connected to the connection detection module 4 and the display module 6 after passing through the receiving cavity 7; the two self-locking modules 3 are respectively fixedly connected to both sides of the support base 21.

[0032] Specifically, as Figure 2-3 shown, the design of the plugging mechanism 2 has a combination of a plurality of conductive columns 22 and insulating columns 23, which increases electrical safety and insulation performance and reduces the risk of short circuit; at the same time, the modular structure design makes the maintenance and replacement process simple and worry-free.

[0035] Specifically, Figure 4 As shown, when the plug 33 is inserted into the socket 34, the spring block 322 at the front end of the clamping rod 32 on the plug 33 will first abut against the trigger block 342 of the self-locking rod 341 in the clamping groove 341. When abutting, the spring block 322 pops up to drive the self-locking rod 341 to rotate, so that the clamping block 343 on the other end of the self-locking rod 341 abuts against the protrusion 321 on the clamping rod 32, thereby realizing the limiting effect of the clamping rod 32 in the clamping groove 341, and realizing the plug 33 The self-locking between the plug 33 and the socket 34 makes the connection more secure; in the process of separating the plug 33 from the socket 34, the self-locking rod 341 is rotated by the reset button 35, and the spring block 322 is pressed down again by the trigger block 342, so that the self-locking rod 341 drives the clamping block 343 to move, so that the clamping block 343 and the protrusion 321 are no longer abutted. At this time, the plug 33 can be pulled out to separate the plug 33 and the socket 34, which is convenient for the operator to disassemble, inspect, disassemble and replace.

[0040] Specifically, the connection detection module 4 combines the first and second sensors 44 and is respectively arranged inside the socket 34 and the insulating housing 11. When the plug 33 is not fully inserted or not inserted, the first indicator light 41 lights up red to indicate that the connection is unsuccessful. When the plug 33 is fully inserted, the first indicator light 41 lights up green to indicate that the connection is successful; when the internal circuit of the meter body 1 and the internal circuit of the plug-in mechanism 2 are not conducting, the second indicator light 42 lights up red to prompt the user to check the connection.

[0049] Further, step B further includes: when the connection detection module 4 detects that the plugging mechanism 2 is not connected, the display module 6 is used to prompt the user "Please connect".

[0050] Specifically, step B in the operation monitoring method can be further improved to timely feedback the user operation; when the connection detection module 4 detects that the plugging mechanism 2 is not connected, the system alarms through the display module 6 at the same time to remind the user "Please connect the plug 33", which enhances the user interaction experience and significantly improves the operation safety.
