A single-phase intelligent electric meter plug-in structure

Abstract

This application relates to the technical field of smart meters, and in particular to a single-phase smart meter plug-in structure, including a main body. An assembly block is fixedly connected to the back of the main body, and a rotating cover is rotatably connected to the front of the main body. The rotating cover provides protection for the device. There are two assembly blocks. This invention incorporates components such as a pulley, a fixing block, and a second pulley. The operator simply aligns the two connectors of the cable with the sides of the fixing block and pushes it forward. The two connectors then contact the second pulleys on both sides of the fixing block. Simultaneously, the first pulleys on both sides also contact the connectors. At this point, the first pulleys on both sides and the second pulleys on both sides of the fixing block form a movable clamping state for the cable, allowing the two connectors of the cable to smoothly enter the assembly slot. This reduces the time required for operators to adjust the angle of the cable connectors, improves work efficiency, and speeds up installation.

Description

Technical Field

[0001] This application relates to the technical field of smart meters, and in particular to a single-phase smart meter plug-in structure. Background Technology

[0002] Single-phase smart meters are mainly used to measure active power in single-phase circuits. They can accurately measure the electricity consumed by users and store and process the data. Compared with traditional mechanical meters, single-phase smart meters no longer rely on mechanical discs to measure electricity. Instead, they use advanced electronic technology and microprocessors to calculate electrical energy by sampling and analyzing voltage and current signals.

[0003] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: In the prior art, when the meter is connected to the 485 cable, since the 485 cable consists of two connecting wires, workers need to twist it during the connection process. This results in workers spending a lot of time fine-tuning the twisting angle, which not only increases the workload of workers but also slows down the installation progress. Utility Model Content

[0004] To reduce the time required for workers to adjust cables, this application provides a single-phase smart meter plug-in structure.

[0005] This application provides a single-phase smart meter plug-in structure, which adopts the following technical solution: it includes a main body, an assembly block is fixedly connected to the back of the main body, and a rotating cover is rotatably connected to the front of the main body. The rotating cover can protect the device. The number of assembly blocks is two.

[0006] The main body has an installation groove on the front side, and a fixing block is fixedly connected to the back of the inner wall of the installation groove. The fixing block has slots on both the left and right sides. The inner wall of the slot on the left side is rotatably connected to a pulley. The right side of the fixing block has a pulley. The bottom of the inner wall of the installation has an assembly groove.

[0007] Optionally, a fixing box is fixedly connected to the back of the inner wall of the mounting groove, a movable plate is slidably connected to the inner wall of the fixing box, and a spring telescopic column is fixedly connected to the right side of the movable plate. The right side of the spring telescopic column is fixedly connected to the right side of the inner wall of the fixing box.

[0008] Optionally, the left side of the movable plate is rotatably connected to a pulley via a pin, and there are two fixing boxes, which are symmetrically arranged with the fixing block as the center.

[0009] Optionally, the number of pulleys two is several, and the several pulleys two are arranged symmetrically; the number of pulleys one is several, and the several pulleys one are arranged in a vertical array.

[0010] Optionally, a second fixing block is in contact with the back of the mounting groove, a connecting block is fixedly connected to the bottom of the second fixing block, a threaded hole is opened on the front of the second fixing block, a fixing screw is threadedly connected to the inner wall of the threaded hole, and a movable groove is opened on the right side of the second fixing block.

[0011] Optionally, a spring telescopic column two is fixedly connected to the left side of the inner wall of the movable groove, and a movable block one is fixedly connected to the right side of the spring telescopic column two. A sliding groove is provided on the back of the main body, and a connecting column is slidably connected to the inner wall of the sliding groove. A movable block two is fixedly connected to the front of the connecting column.

[0012] Optionally, a pressing plate is fixedly connected to the back of the connecting column, a limiting groove is provided on the back of the pressing plate, a spring column is slidably connected to the inner wall of the limiting groove, the front of the second moving block is in contact with the back of the first moving block, and a limiting groove is provided on the inner wall of the sliding groove near the second moving block.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. This utility model, by providing components such as pulley one, fixing block one, and pulley two, allows workers to simply align the two connectors of the cable with the two sides of fixing block one and push them forward. This causes the two connectors to contact pulley two on both sides of fixing block one, while pulley one on both sides also contacts the connectors. At this point, pulley one on both sides and pulley two on both sides of fixing block one form a movable clamping state for the cable, allowing the two connectors of the cable to smoothly enter the assembly slot. This reduces the time workers spend adjusting the angle of the cable connectors, improves work efficiency, and speeds up installation.

[0015] 2. This utility model includes components such as a fixed block two, a spring telescopic column two, and a movable block one. Because the bottom of the movable block is sloped, the operator can align the fixed block two with the assembly slot and press it downwards. Since the movable block one is connected via the spring telescopic column two, it will retract inwards. When the movable block one enters the limiting slot, it will extend again and contact the movable block two. At this point, the operator can tighten several fixing screws to secure the cable connector. When disassembly is required, the movable block one can be disassembled by pushing the pressing plate forward to release it from the limiting slot. This allows for quick cable assembly using a plug-in structure, making the device more convenient to use. Attached Figure Description

[0021] The following is in conjunction with the appendix Figures 1-4 This application will be further described in detail below. The technical solutions in the embodiments of this application will be clearly described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0022] This application discloses a single-phase smart meter plug-in structure. For example... Figure 1 , Figure 2 As shown, it includes a main body 1, characterized in that: an assembly block 11 is fixedly connected to the back of the main body 1, and a rotating cover 12 is rotatably connected to the front of the main body 1, and the number of assembly blocks 11 is two.

[0023] In this embodiment, the main body 1 has an installation groove on the front side, and a fixing block 24 is fixedly connected to the back of the inner wall of the installation groove. The fixing block 24 has slots on both the left and right sides. The inner wall of the slot on the left side is rotatably connected to a pulley 241. A pulley 211 is provided on the right side of the fixing block 24. The middle of both pulley 211 and pulley 241 is recessed so that they can form a clamping space to restrict the cable connector. An assembly groove 23 is provided at the bottom of the inner wall of the installation.

[0024] Please see Figure 3 As shown, a fixing block 2 3 is in contact with the back of the mounting slot. A threaded hole is opened on the front of the fixing block 2 3. A fixing screw 32 is threadedly connected to the inner wall of the threaded hole. Several fixing screws 32 are threadedly connected to the threaded hole on the fixing block 2 3. All fixing screws 32 can be taken away when the fixing block 2 3 is disassembled, so as to avoid the fixing screws 32 being lost after disassembly. A connecting block 31 is fixedly connected to the bottom of the fixing block 2 3. A movable slot is opened on the right side of the fixing block 2 3.

[0025] Please see Figure 2As shown, a fixed box 2 is fixedly connected to the back of the inner wall of the mounting slot. A movable plate 21 is slidably connected to the inner wall of the fixed box 2. A spring telescopic column 22 is fixedly connected to the right side of the movable plate 21. The spring telescopic column 22 can make the movable plate 21 always drive the pulley 211 to contact the cable connector. The right side of the spring telescopic column 22 is fixedly connected to the right side of the inner wall of the fixed box 2.

[0026] Please see Figure 3 As shown, a spring telescopic column 2 33 is fixedly connected to the left side of the inner wall of the movable groove, and a movable block 1 331 is fixedly connected to the right side of the spring telescopic column 2 33. A sliding groove is provided on the back of the main body 1.

[0027] Please see Figure 2 As shown, the left side of the movable plate 21 is rotatably connected to the pulley 211 via a pin. There are two fixed boxes 2, which are symmetrically arranged with the fixed block 24 as the center.

[0028] Please see Figure 4 As shown, a connecting column 341 is slidably connected to the inner wall of the sliding groove. A second movable block 34 is fixedly connected to the front of the connecting column 341. The front of the second movable block 34 is set with an incline. The second movable block 34 with the incline is adapted to the first movable block 331. A pressing plate 35 is fixedly connected to the back of the connecting column 341. A limiting groove is opened on the back of the pressing plate 35. A spring column 351 is slidably connected to the inner wall of the limiting groove. The front of the second movable block 34 is in contact with the back of the first movable block 331. A limiting groove is opened on the side of the inner wall of the sliding groove near the second movable block 34.

[0029] Please see Figure 2 As shown, there are several pulleys 241, which are arranged symmetrically, and several pulleys 211, which are arranged in a vertical array.

[0030] The implementation principle of the single-phase smart meter plug-in structure in this application embodiment is as follows: The operator only needs to align the two connectors of the cable with the two sides of the fixing block 24 and push them forward to make the two connectors contact the pulleys 241 on both sides of the fixing block 24. Simultaneously, the pulleys 211 on both sides will also contact the connectors. Under the action of the spring telescopic column 22, the pulleys 211 will always be tightly fitted with the cable. Since both pulleys 211 and 241 have recessed centers, the pulleys 211 and 241 on both sides of the fixing block 24 form a movable clamping state for the cable, while also fixing the cable connectors. This facilitates subsequent assembly, allowing the two connectors of the cable to smoothly enter the assembly slot 23, reducing the operator's workload on the cable connection. The reduced head angle adjustment time improves worker efficiency and speeds up installation. Because the bottom of the movable block 331 is angled, workers can align the fixed block 3 with the assembly slot 23 and press it down. Since the movable block 331 is connected by the spring telescopic column 33, it will retract inwards. When the movable block 331 enters the limiting slot, it will extend again and contact the movable block 34. At this point, workers can tighten several fixing screws 32 to secure the cable connector. When disassembly is required, all fixing screws 32 can be loosened, and the movable block 331 can be disassembled by pushing the pressing plate 35 upwards to release it from the limiting slot. This allows for quick cable assembly using a plug-in structure, making the device more convenient to use.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
