Description

Technical Field

[0001] This utility model relates to the field of electricity meter technology, specifically a novel electricity meter. Background Technology

[0002] With the rapid development of society and the economy, various electrical equipment have sprung up like mushrooms after rain, and their application scenarios are constantly expanding, from daily household electricity use to industrial production and commercial operations. Their functional and performance requirements are also becoming increasingly diversified and sophisticated. In this wave of development, the importance of electricity meters, as the core tool for electricity metering and management, is becoming increasingly prominent. The industry's requirements for electricity meters in terms of metering accuracy, data transmission, functional expandability, and adaptability to complex environments are also constantly increasing.

[0003] In many practical applications, such as electricity metering in different production workshops within large industrial parks, energy consumption statistics for various businesses in commercial complexes, and power monitoring in different functional areas of smart buildings, multiple electricity meters often need to operate collaboratively to achieve accurate metering, data aggregation, and efficient management of different electricity-consuming units. However, traditional single-structure electricity meters, due to design limitations, exhibit significant shortcomings in these multi-meter collaborative scenarios: each meter requires independent installation and wiring, which not only occupies a large amount of space but also leads to messy wiring, increasing the difficulty of installation and maintenance; at the same time, data exchange between meters is inconvenient, making centralized and intelligent management difficult, and failing to meet the demands of modern power systems for efficient, accurate, and intelligent metering. Therefore, developing an electricity meter that can be easily assembled and combined, allowing for flexible increases or decreases in quantity according to actual usage needs and rapid construction of a collaborative metering system, has become an urgent need for current industry development.

[0004] Furthermore, traditional electricity meters have a critical design flaw: the lack of a limiting platform inside the wiring frame. This oversight makes the wiring terminals highly susceptible to external factors during long-term use, such as vibrations from equipment operation, cable tension, and accidental contact during routine maintenance, leading to loosening in both the vertical and horizontal directions. Loosening of the wiring terminals not only compromises the meter's wiring stability, causing poor contact and resulting in distorted metering data, severely impacting the accuracy and reliability of electricity measurement; more seriously, frequent loosening accelerates terminal wear, potentially causing permanent damage such as deformation and breakage, significantly shortening the meter's lifespan. This increases user equipment replacement costs and maintenance frequency, and may also lead to uninterrupted electricity metering due to sudden malfunctions, causing considerable inconvenience and potential risks to daily life and production. Summary of the Invention

[0005] The purpose of this utility model is to provide a new type of electricity meter to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A novel electricity meter includes an electricity meter housing. One end face of the electricity meter housing has an installation cavity, and a splicing assembly is installed within the installation cavity. The other end face of the electricity meter housing has a splicing groove that mates with the splicing assembly, located opposite to the installation cavity. The electricity meter housing is interlocked with the splicing groove of another electricity meter housing via the splicing assembly. A latch for engaging the splicing assembly is located on the surface of the electricity meter housing relative to the installation cavity. Terminal blocks are installed at both the front and rear ends of the electricity meter housing. Multiple wiring ports are provided on both the front and rear surfaces of the electricity meter housing. Terminal ports are located opposite to the wiring ports on the terminal blocks, and limit platforms are symmetrically fixedly connected to the inner walls of the terminal ports.

[0007] Preferably, a threaded hole is provided in the middle of one end face of the electricity meter housing, and a guide rod is threadedly connected through the threaded hole. A guide hole is provided in the other end face of the electricity meter housing at the position opposite to the guide rod, and a guide rod is inserted into the guide hole.

[0008] Preferably, the splicing assembly includes a base, a connecting part, and a connecting arm. The base and the connecting arm are respectively connected to both ends of the connecting part, and the base, the connecting part, and the connecting arm adopt an integrated molding design. The base is installed in the mounting cavity, and the connecting arm is snapped into the splicing groove.

[0009] Preferably, an elastic snap-fit ​​block is fixedly connected to the rear end surface of the base, and the elastic snap-fit ​​block snaps into the slot.

[0010] Preferably, a wiring frame is movably connected inside the terminal opening, a copper busbar is installed between the limiting platform and the inner wall of the terminal opening, a connection hole is opened at the top of the wiring frame, a through hole is opened on the top surface of the wiring terminal block at a position opposite to the connection hole, and a screw is rotatably connected inside the through hole, and the surface of the screw is threadedly connected to the connection hole.

[0011] Beneficial effects

[0014] 2. The limiting platforms symmetrically arranged on the inner wall of the terminal opening in this utility model can support the copper busbar inside the terminal opening. Utilizing the cooperation between the copper busbar and the wiring frame, it effectively resists the influence of external factors such as equipment vibration, cable tension, and accidental contact, preventing the wiring frame from loosening, ensuring wiring stability, and reducing metering data distortion caused by poor contact. At the same time, it reduces the risk of terminal wear, deformation, or breakage, significantly extending the service life of the electricity meter, reducing user equipment replacement costs and maintenance frequency, and avoiding electricity metering interruptions caused by malfunctions.

[0015] 3. The splicing components of this utility model adopt an integrated molding design, combined with the snap-fit ​​structure of the elastic snap-fit ​​block and the snap-fit ​​opening, to ensure that the connection of the electricity meter is firm after splicing and not easy to loosen; the wiring frame inside the terminal is stably connected to the electricity meter housing through the screw, and the copper busbar improves the conductivity and connection stability. The overall structural design not only ensures the convenience of installation, but also enhances the reliability and safety of the electricity meter during long-term use.

[0027] like Figure 1-4 This is a schematic diagram of the structure of a novel energy meter according to a preferred embodiment of the present invention. In this embodiment, the novel energy meter includes an energy meter housing. One end face of the energy meter housing 1 has a mounting cavity 11, in which a splicing component 2 is installed. The other end face, located opposite to the mounting cavity 11, has a splicing groove 12 that mates with the splicing component 2. The energy meter housing 1 can achieve the splicing function of two energy meters by interlocking the splicing component 2 with the splicing groove 12 of another energy meter housing 1. Simultaneously, a latch 13 for latching the splicing component 2 is located on the surface of the energy meter housing 1 at a position opposite to the mounting cavity 11. The latch 13 facilitates the disassembly and assembly of the splicing component 2 during later use.

[0028] The front and rear ends of the electricity meter housing 1 are equipped with terminal blocks 3, and multiple wiring ports 17 are opened on the surface of both ends. The terminal blocks 3 are provided with terminal ports 31 at the relative positions of the wiring ports 17. The inner walls of the terminal ports 31 are symmetrically fixedly connected to limit platforms 32.

[0029] In addition, a threaded hole 14 is provided in the middle of one end face of the electricity meter housing 1, and a guide rod 15 is threadedly connected through the threaded hole 14. The guide rod 15 is fixed by the threaded connection, which facilitates the disassembly and assembly of the guide rod 15 when needed in later use. A guide hole 16 is provided in the other end face of the electricity meter housing 1 at the position opposite to the guide rod 15. The guide rod 15 can be inserted into the guide hole 16 to play a guiding role in the assembly process.

[0030] In this embodiment, the splicing assembly 2 includes a base 22, a connecting part 21, and a connecting arm 23. The base 22 and the connecting arm 23 are respectively connected to the two ends of the connecting part 21, and the base 22, the connecting part 21, and the connecting arm 23 adopt an integrated molding design. The base 22 is installed in the mounting cavity 11, and the connecting arm 23 is snapped into the splicing groove 12.

[0031] The rear surface of the base 22 is fixedly connected with an elastic snap block 221, which snaps into the slot 13. This design, combined with the integrated molding structure, ensures that the connection of the electricity meter is firm and not easy to loosen after splicing.

[0032] In this embodiment, a wiring frame 33 is movably connected inside the terminal port 31, and a copper busbar 4 is installed between the limiting platform 32 and the inner wall of the terminal port 31. The copper busbar 4 improves conductivity and connection stability.

[0033] The top of the wiring frame 33 has a connection hole 331. The top surface of the terminal block 3 has a through hole 34 located at the opposite position of the connection hole 331. A screw 35 is rotatably connected in the through hole 34. The surface of the screw 35 is threadedly connected to the connection hole 331, so that the wiring frame 33 can move up and down in the terminal opening 31.

[0034] In this embodiment, the limiting platform 32 symmetrically arranged on the inner wall of the terminal port 31 provides support for the copper busbar 4. The rotation of the screw 35 realizes the vertical displacement function of the wiring frame 33. By using the upward displacement of the wiring frame 33, the inner wall surface of the wiring frame 33 cooperates with the bottom surface of the copper busbar 4 to form a clamping and fixing effect on the cable, effectively resisting the influence of external factors such as equipment vibration, cable tension and accidental contact, preventing the wiring frame 33 from loosening vertically and ensuring the stability of the wiring.

[0035] Working principle

[0036] (a) The operation of splicing multiple electricity meters is as follows:

[0037] First, tighten the guide rod 15 on the housing 1 of one of the electricity meters through the threaded hole 14.

[0038] Align the guide hole 16 on the housing 1 of another electricity meter with the guide rod 15 of the electricity meter housing 1 that has been installed with the guide rod 15, and insert the guide rod 15 into the guide hole 16 to achieve initial positioning.

[0039] Next, align the connecting arm 23 of the splicing assembly 2 of the previous energy meter with the splicing slot 12 of the next energy meter, so that the connecting arm 23 is inserted into the splicing slot 12, while ensuring that the elastic snap-fit ​​block 221 on the base 22 of the splicing assembly 2 is inserted into the snap-fit ​​13 on the surface of the energy meter housing 1, thus completing the splicing of the two energy meters.

[0040] The number of electricity meters can be flexibly increased or decreased according to the actual number of electricity-consuming units, following the method described above.

[0041] (II) The wiring operation of the electricity meter is as follows:

[0042] The cable is introduced through the wiring ports 17 at both ends of the electricity meter housing 1.

[0043] Connect the cable to the wiring frame 33 inside the terminal block 31.

[0044] By using an operating tool to rotate the screw 35 inside the through hole 34, the screw 35 is threadedly connected to the connection hole 331 at the top of the wiring frame 33. The rotation of the screw 35 enables the wiring frame 33 to move up and down. By using the upward movement of the wiring frame 33, the inner wall surface of the wiring frame 33 mates with the bottom surface of the copper busbar 4 to clamp and fix the cable.

[0045] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions.
