[0024] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] Example 1 This embodiment provides a digital display multi-functional energy meter that is easy to assemble, as shown in the attached figure. Figures 1-4 As shown, it includes: Cover 1; The base 2 has four first L-shaped limiting blocks 8 and two second L-shaped limiting blocks 9 on its inner wall. The first L-shaped limiting blocks 8 are arranged in pairs on the left and right inner walls of the base 2. Similarly, the second L-shaped limiting blocks 9 are arranged in pairs on the front and rear inner walls of the base 2. One of the watch cover 1 and the base 2 has a locking block 14, and the other has a locking groove 11 that mates with the locking block 14. The engagement of the locking block and the locking groove 11 creates a locking connection.

[0026] The circuit board module includes a power board 5 and a display board 4, with the display board 4 located above the power board 5. The bottom surface of the power board 5 abuts against the bottom of the first L-shaped limiting block 8, providing support and fixation for the power board 5. The sides of the power board 5 abut against the sides of the first L-shaped limiting block 8 and the bottom of the second L-shaped limiting block 9, providing lateral and lateral positioning for the power board 5, and the bottom of the second L-shaped limiting block 9 providing front-rear positioning for the power board 5. The top surface of the first L-shaped limiting block 8 abuts against the display board 4, providing support for the display board 4. The display board 4 abuts against the inner wall of the base 2, and the cooperation between the display board 4 and the base 2 fixes the display board 4 horizontally. When the watch cover 1 is engaged with the base 2, the watch cover 1 and the top surface of the first L-shaped limiting block 8 fix the display board 4 vertically. The power board 5 and the display board 4 are electrically connected. With this structural design, the circuit board module forms a modular structure and is then installed into the base 2. The power board 5 is fixed by the cooperation of the first L-shaped limiting block 8 and the second L-shaped limiting block 9. Furthermore, the display board 4 is fixed by abutting against the inner wall of the base 2, and the display board 4 is supported by the top surface of the first L-shaped limiting block 8 abutting against it. Finally, the connection and fixation between the cover 1 and the base 2 are achieved through the snap-fit ​​mechanism. This structure requires no tools and achieves the overall assembly effect through multi-directional limiting fixation and snap-fit ​​mechanism, making installation convenient and operation simple.

[0027] Specifically, as shown in the attached document Figures 1-3 As shown, the bottom surface of the base 2 is provided with support blocks 7. There are two support blocks 7 here. The support blocks 7 abut against the bottom surface of the power board 5. The two support blocks 7 cooperate with the bottom of the first L-shaped limiting block 8 to form a supporting and fixing effect on the power board 5. The setting of support blocks 7 improves the supporting effect of the power board 5 and prevents the power board 5 from breaking.

[0028] Specifically, as shown in the attached document Figures 1-3 As shown, two locking blocks 14 are symmetrically arranged on the left and right sides of the inner wall of the watch cover 1. A slot 11 corresponding to the locking blocks 14 is provided below the top frame 10 of the base 2. The watch cover 1 is fixed together by the locking blocks 14 and the slots 11.

[0029] Specifically, as shown in the attached document Figures 1-3 As shown, the bottom surface of the base 2 has an opening 12, and the power board 5 has a wiring terminal 19, which is adapted to the opening 12. The wiring terminal 19 is used to form an electrical connection with the outside. In this embodiment, the inner wall of the opening 12 abuts against the outer wall of the wiring terminal 19, forming a limiting and fixing effect on the power board 5, further improving the stability of the power board 5.

[0030] Specifically, as shown in the attached document Figures 1-4 As shown, the power board 5 and the display board 4 are connected by header pins 17. The number of header pins 17 can be adjusted according to actual needs; there can be one, two, three, four, or even more.

[0031] Specifically, as shown in the attached document Figures 1-4 As shown, one of the power board 5 and the display board 4 is provided with a pin header 17, and the other of the power board 5 and the display board 4 is provided with a pin header 17 female connector that connects to the pin header 17. The cooperation between the pin header 17 and the pin header 17 female connector forms an electrical connection between the power board 5 and the display board 4, and an effective connection is formed between the two. By limiting the vertical movement of the display board 4, the power board 5 is also limited, preventing the power board 5 from shaking vertically. Those skilled in the art can adjust the fixed position of the pin header 17 and the pin header 17 female connector according to actual needs.

[0032] Specifically, as shown in the attached document Figures 1-3 As shown, the inner wall of the watch cover 1 is provided with a support column 16, and the base 2 includes a frame 10 located at the top. The support column 16 abuts against the frame 10. The support column 16 is provided to prevent an interference fit between the watch cover 1 and the base 2, which would cause the third limiting block 15 and the limiting column 13 to crush the display panel 4. Furthermore, the cross-section of the support column 16 is semi-circular, and the arc surface of the support column 16 abuts against the frame 10 to prevent an interference fit between the watch cover 1 and the base 2.

[0033] Specifically, as shown in the attached document Figures 1-3 As shown, the cover 1 is provided with a third limiting block 15, which extends toward the base 2 and abuts against the display panel 4.

[0034] Specifically, as shown in the attached document Figures 1-3 As shown, the cover 1 is provided with a limiting post 13, which extends toward the base 2 and abuts against the display panel 4. The third limiting block 15 is in contact with the limiting post 13 and the top of the display panel 4, and cooperates with the first L-shaped limiting block 8 to lock the display panel 4 and prevent the display panel 4 from shaking up and down.

[0035] Specifically, as shown in the attached document Figures 1-3 As shown, a plastic panel 6 is fixed to the watch cover 1, and the plastic panel 6 is transparent. The watch cover 1 adopts a partially hollowed-out design, allowing the information displayed on the LCD screen on the display panel 4 to be read through the plastic panel 6.

[0036] Specifically, it should also be noted that "digital display multi-function energy meter" is a common name in the industry. "Digital display" specifically refers to the information displayed on the LCD screen on display panel 4, and "multi-function" refers to functions such as programmable measurement, display, digital communication, and energy pulse transmission output. The above functions are formed by the cooperation of power board 5 and display panel 4. The data control effect is formed through the cooperation of hardware and software. The above descriptions are all existing technologies. "Digital display multi-function energy meter" is only a name and is not related to the technical solution protected in this embodiment, so it will not be described in detail.

[0037] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
