Description

Technical Field

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

[0002] As a key carrier for electricity metering and distribution control, electricity meters typically have a nameplate structure on their exterior to carry basic equipment attributes and functional information. The design of electricity meter nameplates is primarily based on equipment management, safety regulations, and accountability requirements. Through the fixed presentation of specific technical parameters and labeling content, multi-dimensional functional integration is achieved. For example, core parameters such as model specifications, rated voltage, and current marked on the nameplate can help users or technicians quickly identify the equipment's load capacity and suitable scenarios, thereby avoiding overload risks caused by mismatched electrical parameters. Simultaneously, the manufacturer information, production date, and quality certification marks integrated on the nameplate not only provide visual evidence of product compliance but also establish a data link for tracing accountability in quality disputes.

[0003] In existing technologies, nameplates are typically fixed to the exterior of the electricity meter for quick identification of technical parameters and certification information. However, if the installation location is near high-temperature, humid, or vibrating areas, the nameplate is susceptible to environmental influences, leading to blurred information or material aging. Furthermore, nameplates are generally anchored to the equipment surface using screws, nuts, or rivets, or glued. However, screw installation requires drilling, which may damage the protective layer of the equipment surface, increasing the risk of corrosion; screws are prone to loosening in vibrating environments, requiring regular inspection and maintenance; and glued fixation is greatly affected by ambient temperature and humidity, and is prone to delamination over long-term use.

[0004] Therefore, the existing nameplate mounting structure needs to be improved. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an electricity meter that is easy to install and does not easily fall off or age, in view of the above-mentioned technical status.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problem is: an electricity meter, including a housing and a cover disposed on the housing, characterized in that:

[0007] It also includes a nameplate, located on the side of the lid near the box body;

[0008] The lid is transparent; the lid has multiple snap-fit ​​parts, and the nameplate has multiple mounting holes. When the snap-fit ​​parts are inserted into the mounting holes, they deform, and after being inserted into the mounting holes, they return to their original shape, so that the snap-fit ​​parts are snapped into the nameplate.

[0009] Preferably, each of the snap-fit ​​components has a snap-fit ​​groove in the middle to make the snap-fit ​​component elastic. The snap-fit ​​component also includes two arms respectively disposed on both sides of the snap-fit ​​groove; the first end of the arm is connected to the cover and the second end is separate from the cover. When the snap-fit ​​component is inserted into the mounting hole, the two arms disposed at intervals move closer to each other; after the snap-fit ​​component is inserted into the mounting hole, the arms return to their original shape, so that the snap-fit ​​component snaps into the nameplate.

[0010] Preferably, the arm portion is provided with a snap-fit ​​section, a blocking section, and a guide section sequentially from the first end to the second end; the cross-sectional area of ​​the blocking section is larger than the cross-sectional area of ​​the snap-fit ​​section and the guide section, and the blocking section prevents the nameplate from shifting relative to the cover. The nameplate is mounted on the snap-fit ​​section after installation.

[0011] To facilitate the snap-fit ​​of the nameplate, preferably, the length of the snap-fit ​​segment is greater than or equal to the thickness of the nameplate.

[0012] To facilitate the removal or replacement of the nameplate when necessary, preferably, the connection between the blocking section and the guide section is chamfered.

[0013] To facilitate reading the meter reading, preferably, the cover is provided with a mounting slot for an external proximity infrared probe.

[0014] Preferably, the box cover is recessed to form a mounting portion for placing the near-infrared probe, and the mounting groove has two sides disposed on the mounting portion.

[0015] To secure the nameplate and prevent it from falling off, preferably, the snap-fit ​​element is located on the four edges of the nameplate.

[0016] Preferably, the electricity meter further includes:

[0017] The PCB board is located inside the enclosure and has a power management module;

[0018] The signal lights are multiple and mounted on a PCB board, which provides power to the signal lights.

[0019] The box cover is equipped with multiple light guide columns corresponding to the signal lights.

[0020] Preferably, the snap-fit ​​component is integrally formed with the box lid.

[0021] Compared with the prior art, the advantages of this utility model are as follows: the box cover is a transparent part, and the nameplate is located inside the box cover. Therefore, the nameplate is covered by the box cover and is not exposed, so it is not easily affected by the environment and is not easy to age and wear. In addition, the nameplate is set on the box cover by multiple snap-fit ​​parts, which is convenient for installation and disassembly, without damaging the structure of the electricity meter and reducing the risk of corrosion.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] like Figure 1-4 The diagram shows a preferred embodiment of the present invention. The electricity meter includes a housing 1, a cover 2 mounted on the housing 1, a nameplate 3, and a PCB board 4. The nameplate 3 is located on the side of the cover 2 near the housing 1, i.e., on the inside of the cover 2; the cover 2 is transparent; multiple snap-fit ​​pieces 21 are provided on the inner side of the cover 2, and correspondingly, the nameplate 3 has multiple mounting holes 31. When the snap-fit ​​piece 21 is inserted into the mounting hole 31, it deforms; after insertion, it returns to its original shape, thus engaging with the nameplate 3. Figure 4 As shown, each snap-fit ​​component 21 includes two spaced-apart arms 211. The first end of each arm 211 is connected to the lid 2, and the second end is separate from the lid 2. From the first end to the second end, each arm 211 has a snap-fit ​​section 212, a blocking section 213, and a guide section 214. The cross-sectional area of ​​the blocking section 213 is larger than that of the snap-fit ​​section 212 and the guide section 214, preventing the nameplate 3 from shifting relative to the lid 2. The length of the snap-fit ​​section 212 is greater than or equal to the thickness of the nameplate 3. A chamfer is provided at the connection between the blocking section 213 and the guide section 214. A chamfer is also provided at the connection between the blocking section 213 and the snap-fit ​​section 212. The snap-fit ​​component 21 is located on the periphery of the nameplate 3, facilitating the fixation of the nameplate 3. The snap-fit ​​component 21 is integrally formed with the lid 2.

[0028] The cover 2 is provided with an assembly groove 22 for an external proximity infrared probe; the outer surface of the cover 2 is recessed to form a mounting part 23 for placing the proximity infrared probe, and the assembly groove 22 has two sides provided on the mounting part 23.

[0029] The PCB board 4 is located inside the housing 1 and has a power management module; the PCB board 4 has multiple indicator lights, and the power management module of the PCB board 4 provides power to the indicator lights; the housing cover 2 has multiple light guide columns 24 corresponding to the indicator lights.

[0030] During assembly in this embodiment, an external force causes the snap-fit ​​member 21 to deform when inserted into the mounting hole 31. That is, the two corresponding arms 211 move closer together under the action of the external force, thus facilitating the insertion of the snap-fit ​​member 21 into the mounting hole 31. After the snap-fit ​​member 21 is inserted into the mounting hole 31, the external force is removed, and the snap-fit ​​member 21 returns to its original shape, so that the blocking section 213 of the snap-fit ​​member 21 restricts the displacement of the nameplate 3. At this time, the nameplate 3 is placed on the snap-fit ​​section 212. After installation, one side of the nameplate 3 is tightly attached to the cover 2, which is not easily affected by the environment, and the information engraved on the nameplate 3 is not easily disappeared or deformed.
