[0002] An electric energy meter is an instrument used to measure electrical energy, also known as an electric meter, fire meter, or kilowatt-hour meter. It refers to an instrument that measures various electrical quantities.

[0003] When connecting existing electric energy meters, the insulation layer on the outside of the wire is generally stripped off to expose the wire inside the line, and then the wire is placed in the wiring hole of the meter and fixed in the wiring hole with screws.

[0004] However, when a large number of wires are connected to the electricity meter, it is necessary to repeatedly tighten the screws. At the same time, when a problem occurs with the electricity meter and the wires need to be removed from the electricity meter, it is also necessary to repeatedly loosen the screws one by one and remove the wires from the wiring holes, which is time-consuming and labor-intensive, affecting the efficiency of installation and removal. In view of this, we propose a quick-release structure for a plug-in electricity meter. Utility Model Content

[0029] The convenient mechanism 3 includes a fixing frame 301, which is fixed to the outside of the wiring structure 2. A first handle 302 is provided on the side of the fixing frame 301. The end of the first handle 302 is connected to a limiting rod 303. A limiting ring plate 304 is provided on the outside of the limiting rod 303. A spring 305 is connected to the side of the limiting ring plate 304. The diameter of the end of the first handle 302 is the same as the diameter of the limiting rod 303. The limiting rod 303 and the limiting ring plate 304 are fixedly connected. The limiting ring plate 304 forms an elastic structure with the fixing frame 301 through the spring 305. The utility model effectively drives the limiting rod 303 to move horizontally by pulling the first handle 302 outward, so that the limiting rod 303 is disengaged from the inside of the card rod 206. At this time, the card rod 206 is not constrained. By pulling the second handle 208 outward, the movable plate 207 is effectively driven to move so that the fixed block 209 is disengaged from the fixed groove 202. Then, a number of wires 4 are inserted into the wiring structure 2 one by one, and the movable plate 207 is returned to its position. When the card hole on the side of the card rod 206 is flush with the limiting rod 303, the limiting rod 303 is affected by the rebound force of the spring 305, and is ejected and re-engaged in the inside of the card rod 206, effectively limiting the card rod 206.

[0030] It is worth noting that the wiring structure 2 includes a wiring seat 201, the wiring seat 201 is arranged at the bottom of the electric energy meter body 1, a fixing groove 202 is provided inside the wiring seat 201, a limiting groove 203 is provided below the fixing groove 202, and a limiting frame 204 is engaged internally at the connection between the fixing groove 202 and the limiting groove 203, wherein the fixing groove 202 and the limiting groove 203 are connected, the limiting groove 203 and the limiting frame 204 are fixedly connected, and the limiting frame 204 is hollow and annular, and a symmetrical opening is provided on the surface of the wiring seat 201. The card slot 205 is assembled, and a card rod 206 is engaged inside the card slot 205. It is worth emphasizing that the limit rod 303 passes through the side of the terminal block 201 to reach the inside of the card slot 205 and is engaged with the inside of the card rod 206. A movable plate 207 is connected to the surface of the card rod 206. Furthermore, the card rod 206 is T-shaped, and the movable plate 207 forms a locking structure with the card slot 205 through the card rod 206. A second handle 208 is connected to the middle of the surface of the movable plate 207, and a number of fixed blocks 209 are evenly distributed between a group of card rods 206. In the present invention, the electric wires 4 are effectively aligned and plugged in through the limiting grooves 203, and the insulating wire body 401 is limited by the limiting frame 204 to ensure that only the wire 402 exists in the fixed groove 202. When the terminal block 201 is tightly fitted with the movable plate 207, the fixed block 209 effectively crimps the wire 402 to achieve the simultaneous installation of multiple wires 402. When the terminal block 201 is separated from the movable plate 207, the fixed block 209 and the wire 402 are also separated, to achieve the simultaneous disassembly of multiple wires 402, thereby improving the disassembly and assembly efficiency.

[0031] It is worth noting that the electric wire 4 includes an insulating wire body 401 , and a conductive wire 402 is provided at the end of the insulating wire body 401 .

[0032] Working principle: by pulling the first handle 302 outward, the limiting rod 303 is driven to move horizontally, so that the limiting rod 303 is disengaged from the inside of the card rod 206. At this time, the card rod 206 is not constrained. By pulling the second handle 208 outward, the movable plate 207 is driven to move so that the fixed block 209 is disengaged from the fixed groove 202. Then, a plurality of wires 4 are inserted into the wiring structure 2 one by one. The insulated wire body 401 is aligned and plugged through the limiting groove 203. At the same time, the limiting frame 204 is used to push the insulating wire body 401 against the top to ensure that only the wire 402 exists in the fixing groove 202. Then return the movable plate 207 to its original position. When the card hole on the side of the card rod 206 is flush with the limit rod 303, the limit rod 303 pops out and re-engages inside the card rod 206 under the influence of the rebound force of the spring 305, limiting the card rod 206. At this time, the terminal block 201 is tightly fitted with the movable plate 207, and the fixed block 209 crimps the wire 402 to achieve the simultaneous installation of multiple wires 402. Conversely, when the terminal block 201 is separated from the movable plate 207, the fixed block 209 and the wire 402 are also separated, achieving the simultaneous disassembly of multiple wires 402, thereby improving the disassembly and assembly efficiency.
