[0036] As shown in Figures 1-7 , the outer sliding groove 203 and the outer pulling plate 405 are both symmetrically provided with two, the unlocking assembly 4 further comprises a trigger link 407 and a press alarm 408, the press alarm 408 is fixedly arranged in the connection area cover 2, the trigger link 407 is slidably arranged in the opening and closing slit 202, the bottom of the trigger link 407 is fixedly connected with one of the outer pulling plates 405 away from the U-shaped unlocking link 406, and the trigger link 407 is in contact with the press alarm 408 when it slides to the right limit.

[0037] As shown in Figures 1-7 , the bottom of the inner pulling block 402 is provided with a slot 403.

[0038] As shown in Figures 1-7 , the unlocking assembly 4 further comprises a zero position screw 401 and an outer cap 410, the zero position screw 401 is fixedly arranged below the connection area cover 2, the outer cap 410 is threadedly connected with the zero position screw 401, and the outer pulling plate 405 is clamped in the outer cap 410.

[0039] As shown in Figures 1-7 , the top of the connecting half shell 305 is provided with a round corner transition section.

[0040] Embodiment one, this embodiment is used to describe the working process of the connection area cover 2 when it is normally assembled and disassembled.

[0041] When the wiring needs to be changed, the electrician unscrews the outer cap 410, pulls one of the outer pulling plates 405 connected with the U-shaped unlocking link 406, so that the outer pulling plate 405 moves away from the zero position screw 401. When the outer pulling plate 405 moves, it drives one of the connected connecting half shells 305 to slide left and right through the transmission of the U-shaped unlocking link 406, and makes the lower round corner protruding pin 304 separate from the locking groove 306.

[0042] The bottom of the inner pulling block 402, which was originally blocked by the outer pulling plate 405 and the U-shaped unlocking link 406, is no longer blocked during the process of the outer pulling plate 405 pulling one of the connecting half-shells 305 through the U-shaped unlocking link 406. An electrician can use a flathead screwdriver to insert into the slot 403 of the inner pulling block 402 through the opening and closing gap 202 at the bottom, and slide the other connecting half-shell 305 left and right through the inner pulling block 402 and the L-shaped unlocking link 404, so that the locking groove 306 of the other connecting half-shell 305 is separated from the lower rounded pin 304.

[0043] At this point, the electric energy meter body 1 and the wiring area cover 2 cannot be disassembled due to the locking spring 303 between the column 301 and the connecting half-shell 305, and the lower rounded pin 304. The electrician can pull the wiring area cover 2 down to separate it from the electric energy meter body 1.

[0044] After adjusting the wiring, the electrician puts back the outer cap 410 and makes the outer pulling plate 405 fit in the outer cap 410. Then the wiring area cover 2 is put back from the bottom to the top of the electric energy meter body 1. During this process, the rounded transition section at the top of the connecting half-shell 305 can form a sliding fit with the lower rounded pin 304, so that the locking spring 303 is slightly contracted until the lower rounded pin 304 enters the locking groove 306.

[0045] Example two, this embodiment is used to describe the working process of the press alarm 408 when the electricity thief tries to illegally rewire.

[0046] After the electricity thief breaks the lead seal outside the electric energy meter body 1, the wiring area cover 2 cannot be directly disassembled, then the outer cap 410 is unscrewed and two exposed outer pulling plates 405 are observed. The electricity thief moves the two outer pulling plates 405 away from the zero position screw 401. The trigger link 407 is driven by the outer pulling plate 405 and triggers the press alarm 408, thereby realizing the alarm function.

[0047] The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the technical field can make equivalent substitutions or changes according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
