Guide rail table

Abstract

This utility model relates to the field of electricity meter technology, and more particularly to a guide rail meter. The guide rail meter includes a cover and a base. The cover has an end face with an interface and an opening. The base covers the opening and forms a seam, which is located on the side of the cover and avoids the interface. This not only eliminates the seam on the end face of the cover, improving the aesthetics of the guide rail meter, but also improves the sealing performance of the guide rail meter by placing the seam on the side of the cover, reducing the water leakage phenomenon caused by the seam being located on the end face in traditional technologies. The seam avoidance of the interface on the end face in this utility model allows the interface to be fully presented on the end face. Therefore, during the manufacturing process of the cover and base, only an insert / core-pulling structure needs to be set on the cover mold, thereby reducing mold development costs. At the same time, it avoids the mold-fitting errors caused by the parting mold design in traditional technologies, improving the yield rate of the cover and base assembly.

Description

Technical Field

[0001] This utility model relates to the field of electricity meter technology, and in particular to a rail meter. Background Technology

[0002] As a crucial piece of equipment in the field of electricity metering, the structural design of DIN rail meters directly impacts installation efficiency and long-term stability. With the advancement of smart grid construction, the market is placing higher demands on DIN rail meters: they must meet multiple functions such as time-of-use billing and data acquisition, while also achieving high protection levels (e.g., IP65) within a compact space. Traditional DIN rail meters often employ a split cover and base structure, integrating functions through the splicing of multiple components. However, with the increasing demand for integrated equipment appearance and cost reduction in high-end applications, the existing DIN rail meter structure is gradually revealing numerous shortcomings.

[0003] Existing split-type guide rail gauge structures tend to form noticeable seams at the joint surface between the cover and the base. This not only affects the overall aesthetics of the product but may also lead to insufficient sealing, resulting in reliability issues such as water leakage and dust ingress under complex operating conditions. Furthermore, existing guide rail gauges often have one part of the same interface located on the cover and the other part on the base. This necessitates the use of insert / core-pulling structures in both the cover and base molds during interface fabrication, increasing mold development costs. In addition, the split mold design is prone to mold-closing errors, reducing the yield rate of cover and base assembly.

[0004] Therefore, there is an urgent need to design a guide rail table to solve the above technical problems. Utility Model Content

[0054] The embodiments of this utility model are described in detail below.

[0055] This embodiment provides a guide rail gauge that improves the product's aesthetics and sealing performance, reduces mold development costs, and increases the yield rate of cover and base assembly.

[0056] like Figures 1-9 As shown, the guide rail meter mainly includes a cover 10 and a base 20. The cover 10 has an end face 11 with an interface 12 and an opening. The base 20 covers the opening, forming a seam 21. The seam 21 is located on the side of the cover 10 and avoids the interface 12. This not only eliminates the seam 21 on the end face 11 of the cover 10 (i.e., the front of the cover 10), improving the aesthetics of the guide rail meter, but also improves the sealing performance of the guide rail meter by placing the seam 21 on the side of the cover 10, reducing the water leakage phenomenon caused by the seam being located on the end face in traditional technologies. Furthermore, in this embodiment, the seam 21 avoids the interface 12 on the end face 11, allowing the interface 12 to be fully presented on the end face 11. Therefore, during the manufacturing process of the cover 10 and the base 20, only an insert / core-pulling structure needs to be set on the mold of the cover 10, thereby reducing the mold development cost. At the same time, it can avoid the mold closing error caused by the mold splitting design in traditional technology, and improve the yield rate of the assembly of cover 10 and base 20.

[0057] In this embodiment, a first positioning post 13 is provided inside the cover 10, and a second positioning post 22 corresponding to the first positioning post 13 is provided on the base 20. The first positioning post 13 is sleeved on the second positioning post 22, which can improve the assembly efficiency of the cover 10 and the base 20, and also avoid the phenomenon of relative misalignment between the two during use.

[0058] like Figures 3-9 As shown, in this embodiment, the guide rail also includes a circuit board 30. The cover 10 and the base 20 form a receiving cavity, and the first positioning post 13 is disposed on the bottom wall of the receiving cavity. The circuit board 30 is provided with a positioning hole 31 and a connector 32. The positioning hole 31 is sleeved on the first positioning post 13, and the connector 32 is snapped onto the interface 12 (connector interface 121). The circuit board 30 is installed in the receiving cavity. The arrangement of the first positioning post 13 and the positioning hole 31 can improve the assembly efficiency and accuracy of the circuit board 30, and can also provide support for the circuit board 30, preventing the circuit board 30 from falling or shifting in the receiving cavity.

[0059] In this embodiment, multiple connectors 32 and interfaces 12 can be configured. The connector 32 is snapped into the interface 12 to facilitate connection with external signal lines.

[0060] like Figure 13 As shown, the circuit board 30 in this embodiment requires an inclined assembly method during assembly. Specifically, the operator places the end of the circuit board 30 away from the connector 32 into the receiving cavity at an inclined position and presses it against the side wall of the receiving cavity. Then, the entire circuit board 30 is pressed into the receiving cavity. At this time, the connector 32 is located at the interface 12. The operator only needs to press the connector 32 with a little force to snap the connector 32 into the interface 12.

[0061] like Figures 10-11 As shown, in this embodiment, the guide rail also includes a light guide 40, and an elastic limiting member 14 is provided on the bottom wall of the accommodating chamber. The light guide 40 is snapped into the elastic limiting member 14, thereby realizing the assembly of the light guide 40 and the cover 10. The elastic limiting member 14 can snap and limit the light guide 40, preventing the light guide 40 from falling or shaking during use.

[0062] In this embodiment, the circuit board 30 is provided with multiple light-emitting elements of different colors, and the end face 11 of the cover 10 is provided with a light-transmitting hole 15. One end of the light guide 40 is provided corresponding to the light-emitting element, and the other end of the light guide 40 is provided corresponding to the light-transmitting hole 15. The light generated by the light-emitting element can pass through the light guide 40 and shine through the light-transmitting hole 15 to the outside of the cover 10, which makes it convenient for operators to monitor the working status of the guide rail gauge.

[0063] Furthermore, in this embodiment, the circuit board 30 is provided with a clearance position 33, which is configured to avoid the elastic limiting member 14, thereby preventing the circuit board 30 from interfering with the elastic limiting member 14, improving the efficiency of assembling the circuit board 30 and the cover 10, and protecting the circuit board 30.

[0064] like Figures 10-11 As shown, the light guide 40 in this embodiment includes a connecting plate 41 and multiple light guide pillars 42. The light guide pillars 42 are connected to the connecting plate 41, and the connecting plate 41 is snapped into place with the elastic limiting member 14. The light guide pillars 42 have a hollow structure. Multiple light-emitting elements of different colors (not shown in the figure) are disposed on the circuit board 30, and each light guide pillar 42 is positioned opposite a light-emitting element of a specific color. The light emitted by the light-emitting elements can pass through the hollow light guide pillars 42 and illuminate the outside of the cover 10. The connecting plate 41 can fix multiple light guide pillars 42, facilitating the integration of multiple light guide pillars 42 onto the connecting plate 41, improving the integration of the light guide 40 and reducing its size.

[0065] Optionally, the connecting plate 41 and the light guide post 42 can be integrally formed to improve processing efficiency.

[0066] Optionally, the light guide pillars 42 can be set to two, three, or other quantities.

[0067] Optionally, the light-emitting element in this embodiment can be a commercially available LED light source, which is small in size and easy to integrate onto the circuit board 30, and the color of the LED light source can be flexibly selected according to actual needs.

[0068] Please continue to refer to this. Figures 10-11 In this embodiment, the connecting plate 41 is provided with limiting ribs 411, which are snapped together with the elastic limiting member 14 to realize the assembly relationship between the light guide 40 and the elastic limiting member 14. Optionally, multiple limiting ribs 411 are provided to improve the stability of the snap-fit ​​connection with the elastic limiting member 14 and reduce or avoid the risk of the light guide 40 shaking or even falling off.

[0069] Please continue to refer to this. Figures 10-11 In this embodiment, the light guide column 42 includes a column body 421 and a column head 422. One end of the column body 421 is connected to one end of the column head 422, and the other end of the column body 421 is positioned directly opposite the light-emitting element. The other end of the column head 422 passes through the connecting plate 41 and is inserted into the light-transmitting hole 15.

[0070] The column 421 extends to the light-emitting element, and the column head 422 is located in the light-transmitting hole 15 on the end face 11 of the cover 10, preventing the connecting plate 41 or the cover 10 from blocking the light. The light generated by the light-emitting element can pass through the hollow column 421 and be irradiated outside the cover 10 through the column head 422, so that the operator can monitor the working status of the guide rail gauge.

[0071] Optionally, in this embodiment, the base 20 is further provided with a light-blocking member 23, which is inserted between two adjacent columns 421. The light-blocking member 23 is configured to prevent light rays passing through the two adjacent columns 421 from interfering with each other. This prevents light from interfering with each other between the two adjacent columns 421. For example, if the two columns 421 are very close together, the light they emit may interfere with each other, resulting in unclear display and the user may not be able to accurately read the information. Therefore, in this embodiment, the light-blocking member 23 can physically isolate the two columns 421, ensuring that the light from each column 421 is only displayed within its predetermined area, thus avoiding light interference.

[0072] like Figures 4-6 , Figure 12 As shown, in this embodiment, a button hole 16 is provided on the end face 11 of the cover 10, an elastic plate 24 is provided on the base 20, and a reset button 34 is provided on the circuit board 30. The button hole 16 is positioned directly opposite the elastic plate 24, and the elastic plate 24 is positioned directly opposite the reset button 34. In other words, the button hole 16, the elastic plate 24, and the reset button 34 are arranged in a straight line. When the operator needs to reset the guide rail gauge, the operator can use a specific tool to pass through the button hole 16 and apply a certain pressure to the elastic plate 24, causing the elastic plate 24 to undergo elastic deformation and move downwards, pressing the reset button 34 on the circuit board 30, thereby completing the reset of the guide rail gauge.

[0073] In this embodiment, the elastic plate 24 and the base 20 are integrally formed, which reduces the number of structural parts, simplifies the assembly process, improves the assembly efficiency of the guide rail, and saves costs.

[0074] like Figures 7-8 As shown, in this embodiment, an electrostatic baffle 25 is provided on the base 20, and a groove is provided on the inner side of the cover 10. The electrostatic baffle 25 is inserted into the groove to form a nested structure, thereby improving the stability and reliability of the assembly between the cover 10 and the base 20. The electrostatic baffle 25 is configured to absorb or transfer electrostatic energy. Specifically, the electrostatic baffle 25, through physical isolation or conductive path design, guides externally entering static electricity to a safe area (such as ground or live wire), preventing electrostatic discharge from damaging the circuit components on the circuit board 30.

[0075] like Figure 3 As shown, the guide rail in this embodiment also includes a rivet tube 60. After the cover 10 and the base 20 are assembled, the first positioning post 13 is sleeved on the second positioning post 22. The rivet tube 60 passes through the second positioning post 22 and rivets the cover 10 and the base 20, thereby improving the stability and reliability of the assembly of the cover 10 and the base 20.

[0076] like Figures 1-6 , Figure 9 As shown, in this embodiment, the interface 12 on the end face 11 of the cover 10 also includes an antenna interface 122 and a SIM card interface 123. The guide rail also includes an antenna 50. The circuit board 30 is also provided with a SIM card mounting slot 35. The antenna 50 is plugged into the antenna interface 122, and the SIM card mounting slot 35 is positioned opposite the SIM card interface 123.

[0077] like Figures 13-15 The diagram shows the assembly process of the guide rail table in this embodiment.

[0078] Step 1: Please refer to Figure 13 First, the circuit board 30 is assembled using an inclined assembly method. Specifically, the operator places the end of the circuit board 30 away from the connector 32 into the receiving cavity at an inclined position and presses it against the side wall of the receiving cavity. Then, the entire circuit board 30 is pressed into the receiving cavity. At this time, the connector 32 is located at the interface 12 (connector interface 121). The operator only needs to press the connector 32 slightly to snap it into the interface 12 (connector interface 121).

[0079] Step Two: Please refer to Figure 14 Connect the antenna 50 to the antenna interface 122 and snap the light guide 40 onto the elastic limiting member 14 on the cover 10.

[0080] Step 3: Please refer to Figure 15 The base 20 is placed over the opening to form a seam 21, ensuring that the first positioning post 13 is fitted onto the second positioning post 22; then the rivet tube 60 is inserted inside the second positioning post 22 and riveted to the cover 10 and the base 20. The assembly of the guide rail is then complete.
