Description

Technical Field

[0001] This utility model relates to the field of smart meter technology, specifically to a smart meter housing structure with leakage protection function. Background Technology

[0002] Smart meters are a new type of electricity metering instrument with digital metering, two-way communication, data storage and intelligent analysis functions. At its core, they replace traditional mechanical meters or simple electronic meters by using technologies such as the Internet of Things, embedded chips and sensors to achieve refined monitoring, remote management and interactive services for electricity consumption. They are the core infrastructure of the electricity consumption side of the smart grid.

[0003] When installing leakage protection devices on smart meters, external or fixed welding methods are often used for connection. This means that the smart meter needs to be disassembled when the leakage protection device is maintained or replaced, resulting in low maintenance efficiency. Furthermore, repeated disassembly and reassembly make the maintenance operation cumbersome and not conducive to quick maintenance and replacement work by staff. Utility Model Content

[0004] The purpose of this utility model is to provide a smart meter housing structure with leakage protection function to solve the problems in the background art mentioned above.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A smart meter housing structure with leakage current protection function includes: a housing, a display structure electrically connected to the upper surface of the housing for displaying the overall data of the device, a wiring structure at the end of the housing away from the display structure, a top cover at the top of the wiring structure that is snap-fitted to the housing, and a leakage current protection mechanism electrically connected to one end of the wiring structure; the leakage current protection mechanism includes side plates symmetrically installed on both sides of the end of the housing near the wiring structure, a locking block fixedly installed on the inner side of the side plates, a leakage current protection device inserted into the end of the housing, a symmetrical slot for engaging with the locking block at the end of the leakage current protection device near the housing, and a plurality of plug-in pins equidistantly connected to the end of the leakage current protection device near the housing, with one end of each plug-in pin electrically connected to the wiring structure.

[0006] Using the above technical solution, during normal use of the device, the staff first fixes and installs the casing, and then electrically connects the leakage protection mechanism to the wiring structure. The leakage protection mechanism adopts a modular design, which can quickly and accurately snap onto the casing. Compared with the cumbersome assembly and alignment operation mode required by external or fixed welding methods, the modular snap-on method greatly simplifies the installation process. It not only reduces the difficulty of operation for the staff and reduces the installation error caused by the complexity of operation, but also significantly shortens the installation time and improves the overall construction efficiency. From the perspective of long-term use and maintenance, the advantages of this design are even more prominent. When the equipment requires routine maintenance, troubleshooting, or parts replacement, the modular leakage protection mechanism eliminates the need to disassemble complex connection structures. Operators can easily disassemble and reinstall the mechanism, significantly reducing downtime during maintenance and repair, minimizing production or operational losses due to equipment shutdown, reducing labor intensity, and mitigating operational risks. Furthermore, the modular design facilitates individual testing and calibration of the leakage protection mechanism, ensuring consistently excellent leakage protection performance and further enhancing the overall electrical safety of the equipment. This provides dual protection for operator safety and stable equipment operation.

[0007] A further improvement of the present invention is that: a number of plug-in blocks are fixedly installed at equal intervals at one end of the leakage current protection device near the housing, and a number of plug-in slots are opened at equal intervals at one end of the housing near the leakage current protection device, and the plug-in blocks and the plug-in slots are plugged in and engaged, and the bottom end of the number of plug-in blocks is provided with a pressing crossbar, and the pressing crossbar is fixedly connected to the side wall of the leakage current protection device.

[0008] Using the above technical solution, when connecting the housing and the leakage current protection device, simply insert the plug-in post on the leakage current protection device into the wiring structure on the housing to complete the electrical fastening connection between the plug-in post and the wiring structure. This completes the assembly connection between the housing and the leakage current protection mechanism. To increase the installation stability between the housing and the leakage current protection mechanism, the ends of the housing are symmetrically equipped with side plates. The snap-fit ​​mechanism with locking blocks and slots allows for quick snap-fit ​​installation of the housing and the leakage current protection mechanism. In addition, to further improve the fit between the plug-in post and the wiring structure, the ends of the leakage current protection device are equipped with plug-in blocks, which can be positioned during the insertion process to increase the accuracy of the device assembly. The crossbar design further enhances the fit between the housing and the leakage current protection device.

[0009] A further improvement of the present invention is that the leakage protection mechanism also includes a bottom groove at the bottom of the leakage protection device. Both ends of the bottom groove are provided with mounting blocks, and the mounting blocks are fixedly connected to the side wall of the leakage protection device. A horizontal groove is provided on the mounting block, and a horizontal rod is slidably connected in the horizontal groove. Both ends of the horizontal rod extend to the outside of the horizontal groove and are fixedly installed with mounting plates. The mounting plates and the side plates are interlocked.

[0010] In order to further improve the snap-fit ​​stability between the housing and the leakage protection device by adopting the above technical solution, after the side plate is snapped into both sides of the leakage protection device, the crossbar is slid along the cross groove so that the mounting plates at both ends of the crossbar slide to the outside of the side plate, thereby restricting the position of the side plate and preventing the side plate from loosening during the snap-fit ​​process, thus further improving the stability of the device during assembly.

[0011] A further improvement of this utility model is that: sliding grooves are symmetrically provided on both sides of the leakage protection device; a slider that slides in cooperation with the sliding groove is symmetrically fixedly installed on the side of the mounting plate near the leakage protection device; a number of abutments are fixedly installed at equal intervals inside the mounting plate; and a number of extrusion grooves that engage with the abutments are equidistantly provided on the outer side of the side plate.

[0012] By adopting the above technical solution, in order to further improve the restriction of the mounting plate on the side plate, the mounting plate is tightly connected to the side wall of the leakage protection device through the sliding fit of the sliding groove and the slider, making the mounting plate more stable and firm when sliding. In addition, the abutment block set on the inner wall of the mounting plate and the extrusion groove set on the outer side of the side plate further improve the snap-fit ​​between the mounting plate and the side plate, and further improve the connection stability of the device.

[0013] A further improvement of this utility model is that: elastic plates are symmetrically fixedly installed at the bottom of the inner side of the transverse groove, a support ring is fixedly installed on the lower surface of the elastic plate, and the bottom of the crossbar is symmetrically provided with mating grooves that are squeezed and matched with the elastic plates.

[0014] By adopting the above technical solution, in order to increase the stability of the mounting plate during operation, an elastic sheet is installed inside the transverse groove, which can form a snap-fit ​​with the mating groove set on the lower surface of the crossbar, so that the mounting plate remains stable when restricting the side plate, thereby further improving the stability of the device.

[0015] A further improvement of this utility model is that several reinforcing ribs are fixedly installed on the outer wall of the side plate.

[0016] By adopting the above technical solution, the reinforcement of the ribs can further improve the strength of the side plate, allowing the side plate to better limit the leakage protection device.

[0017] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: This utility model, with its modular leakage current protection mechanism, eliminates the need to disassemble complex connection structures. Operators can easily disassemble and reinstall the leakage current protection mechanism through simple operations, significantly reducing downtime during maintenance and repair, minimizing production or usage losses caused by equipment shutdowns, reducing labor intensity for maintenance personnel, and lowering operational risks. Furthermore, the modular design facilitates individual testing and calibration of the leakage current protection mechanism, ensuring it maintains excellent leakage current protection performance and further enhancing the overall electrical safety of the device. This provides dual protection for operator safety and stable equipment operation. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to the embodiments.

[0022] Example 1 like Figures 1-5As shown, this utility model provides a smart meter housing structure with leakage protection function, including: a housing 1, a display structure 2 electrically connected to the upper surface of the housing 1 for displaying the overall data of the device, a wiring structure 3 at the end of the housing 1 away from the display structure 2, a top cover 4 at the top of the wiring structure 3, and the top cover 4 and the housing 1 being snap-fitted together, and a leakage protection mechanism 5 electrically plugged into one end of the wiring structure 3; the leakage protection mechanism 5 includes side plates 6 symmetrically installed on both sides of the end of the housing 1 near the wiring structure 3, a locking block 7 fixedly installed on the inner side of the side plate 6, a leakage protection device 8 plugged into the end of the housing 1, and a locking groove 9 symmetrically opened at the end of the leakage protection device 8 near the housing 1 to engage with the locking block 7, and a plurality of plug-in posts 10 electrically connected at equal intervals at the end of the leakage protection device 8 near the housing 1, and one end of the plug-in post 10 being electrically connected to the wiring structure 3.

[0023] In this embodiment, during normal use of the device, the operator first securely installs the housing 1. Then, the operator electrically connects the leakage protection mechanism 5 to the wiring structure 3. The leakage protection mechanism 5 employs a modular design, enabling quick and precise engagement with the housing 1. Compared to external or fixed welding methods that require cumbersome assembly and alignment, the modular engagement method significantly simplifies the installation process. It not only reduces the operator's workload and installation errors caused by complex operations but also significantly shortens installation time and improves overall construction efficiency. From a long-term use and maintenance perspective, the advantages of this design are even more pronounced. When the device needs to be upgraded... During routine maintenance, troubleshooting, or parts replacement, the modular leakage protection mechanism 5 eliminates the need to disassemble complex connection structures. Staff can easily disassemble and reinstall the leakage protection mechanism 5 with simple operations, greatly reducing downtime during maintenance and repair, minimizing production or usage losses caused by equipment shutdown, reducing the labor intensity of staff during maintenance, and lowering operational risks. In addition, the modular design facilitates individual testing and calibration of the leakage protection mechanism 5, ensuring that it always maintains good leakage protection performance, further improving the overall electrical safety of the equipment, and providing dual protection for the operational safety of staff and the stable operation of the equipment.

[0024] Example 2 like Figure 3 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, a plurality of plug-in blocks 11 are fixedly installed at equal intervals at one end of the leakage protection device 8 near the housing 1, and a plurality of plug-in slots 12 are equally spaced at one end of the housing 1 near the leakage protection device 8, and the plug-in blocks 11 and the plug-in slots 12 are plugged into each other, and the bottom end of the plurality of plug-in blocks 11 is provided with a pressing crossbar 13, and the pressing crossbar 13 is fixedly connected to the side wall of the leakage protection device 8.

[0025] In this embodiment, when connecting the housing 1 and the leakage current protection device 8, it is only necessary to insert the plug 10 provided on the leakage current protection device 8 into the wiring structure 3 on the housing 1 to complete the electrical fastening connection between the plug 10 and the wiring structure 3, thereby completing the assembly connection between the housing 1 and the leakage current protection mechanism 5. In order to increase the installation stability between the housing 1 and the leakage current protection mechanism 5, the end of the housing 1 is symmetrically provided with side plates 6, which can be quickly snapped together by the snap-fit ​​setting of the snap-fit ​​block 7 and the snap-fit ​​slot 9. In addition, in order to further improve the plug-in fit between the plug 10 and the wiring structure 3, the end of the leakage current protection device 8 is provided with a plug block 11, which can be positioned during the device plugging process to increase the accuracy of device assembly. The setting of the compression crossbar 13 can increase the installation fit between the housing 1 and the leakage current protection device 8.

Both ends of the bottom groove 14 are provided with mounting blocks 15, and the mounting blocks 15 are fixedly connected to the side wall of the leakage protection device 8.

Both ends of the horizontal rod 17 extend to the outside of the horizontal groove 16 and are fixedly installed with mounting plates 18. The mounting plates 18 are inserted and engaged with the side plate 6.

[0027] In this embodiment, in order to further improve the snap-fit ​​stability between the housing 1 and the leakage protection device 8, after the side plate 6 is snapped onto both sides of the leakage protection device 8, the crossbar 17 is slid along the cross groove 16, so that the mounting plates 18 at both ends of the crossbar 17 slide to the outside of the side plate 6, thereby restricting the position of the side plate 6, preventing the side plate 6 from loosening during the snap-fit ​​process, and further improving the stability of the device during assembly.

A number of abutments 21 are fixedly installed at equal intervals inside the mounting plate 18, and a number of compression grooves 22 that engage with the abutments 21 are provided at equal intervals on the outer side of the side plate 6.

[0029] In this embodiment, in order to further enhance the restrictive effect of the mounting plate 18 on the side plate 6, the mounting plate 18 is tightly slidably connected to the side wall of the leakage protection device 8 through the sliding fit of the sliding groove 19 and the slider 20, making the mounting plate 18 more stable and firm when sliding. In addition, the abutment block 21 provided on the inner wall of the mounting plate 18 and the compression groove 22 provided on the outer side of the side plate 6 further enhance the snap-fit ​​fit between the mounting plate 18 and the side plate 6, and further enhance the connection stability of the device.

[0032] like Figure 2 As shown, preferably, a number of reinforcing ribs 25 are fixedly installed on the outer wall of the side plate 6.

[0033] In this embodiment, the reinforcement rib 25 can further enhance the strength of the side plate 6, allowing the side plate 6 to better limit the leakage protection device 8.
