[0002] In the manufacturing and use of electricity meters, the stable installation of the terminal block is a key factor in ensuring the normal operation of the meter. Currently, some electricity meter terminal blocks are installed using bolt fixing. While this method can guarantee connection strength to a certain extent, it has significant drawbacks. During the meter production and assembly process, fixing the terminal block with bolts requires the use of screwdrivers and other tools to tighten each bolt individually, a cumbersome and time-consuming process that severely impacts production efficiency. In the later maintenance stage, disassembling the bolts is also time-consuming, and frequent disassembly and assembly can easily lead to thread wear, reducing connection reliability. Furthermore, bolts themselves are small components, and they are prone to being lost or misinstalled during assembly, increasing production costs and management difficulty. Therefore, there is an urgent need for an electricity meter terminal block installation structure that eliminates the need for bolts and achieves stable installation, simplifying the assembly process, improving production efficiency and maintenance convenience, and reducing overall costs.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0025] This utility model provides a wiring block mounting structure for an electricity meter.

[0026] In this embodiment, refer to Figure 1-7 The wiring block mounting structure of the electricity meter includes a bottom shell 1, a left upper cover 2, a right upper cover 3, and a wiring block 4. The left upper cover and the right upper cover are fitted onto the bottom shell. A plurality of wiring holes 5 are provided at one end of the bottom shell. An installation step 6 for installing the wiring block is provided inside the bottom shell on one side of the wiring holes 5. A wiring groove 7 communicating with the wiring holes is provided on the installation step 6. A wire outlet 8 is provided on one side of the wiring groove 7. A protruding step 9 and a cylindrical step 10 extend from one side of the wire outlet 8. A connecting post 11 extends from the protruding step 9 and the cylindrical step 10. A pulse hole 12 is provided on the side wall of the bottom shell on one side of the wiring hole 11. Hooks 13 are provided at both ends of the installation step.

[0027] One side of the wiring block extends an alignment step 14, and the alignment step 14 is provided with a connection hole 15 for insertion and mating with the connection post.

[0028] One end of the pulse reserved hole 16 of the wiring block extends into an alignment sleeve 17 that fits into the pulse hole;

[0029] The two ends of the connector block are provided with spring pieces 18, and the spring pieces 18 are provided with hanging holes 19 for connecting with the hooks mentioned above.

[0030] In the above technical solution, stable assembly is achieved by utilizing the corresponding connection structures on the bottom shell and the terminal block, eliminating the need for bolt fixation and ensuring reliable connection. The connecting post at the cable outlet of the bottom shell and the connecting hole on the alignment step of the terminal block are inserted into each other, providing stable positioning for the terminal block; the alignment sleeve of the terminal block fits into the pulse hole of the bottom shell, ensuring accurate positioning of the pulse signal transmission component; at the same time, the hanging hole on the spring piece of the terminal block connects with the hooks at both ends of the mounting step of the bottom shell, further fixing the terminal block and forming a multi-dimensional stable connection system.

[0031] This solution replaces the traditional bolt fixing method with the cooperation of multiple sets of structures, simplifies the installation process, and improves assembly efficiency; it achieves precise positioning and stable connection of the terminal blocks, ensures the stability of electrical connections and the accuracy of pulse signal transmission, reduces measurement errors and failure risks caused by loose terminal blocks, and lowers production and maintenance costs.

[0032] Specifically, the connecting post includes a cylindrical section 20 and a tapered section 21, and the connecting hole is located in a tapered hole that is adapted to the tapered section.

[0033] In this embodiment, the tapered section mates with the matching tapered hole in the connection hole. During the installation of the wiring block, the tapered structure can guide the connection hole to quickly align with the connection post. As the wiring block is installed in place, the tapered surface fits tightly, generating a squeezing and tightening force, which further enhances the stability of the connection.

[0034] Specifically, the bottom shell and the terminal block are provided with continuous sealing grooves 22, and sealing rings are installed in the sealing grooves 22. The upper left cover is provided with a pressing step 23 that can be pressed into the sealing grooves.

[0035] In this embodiment, the sealing grooves on the bottom shell and the end face of the wiring block are used to install the sealing ring. When the upper left cover is closed, the pressing step can press into the sealing groove, squeeze the sealing ring to deform it, fill the gap between the bottom shell, the wiring block and the upper left cover, form a sealing structure, prevent external dust, moisture and other substances from entering the inside of the electricity meter, and improve the sealing performance of the electricity meter shell. In addition, the pressing step presses on the sealing groove of the wiring block, and at the same time presses the wiring block, further improving the stability of the wiring block.

[0036] Specifically, the hook is integrally formed with the mounting step, and a core-pulling hole 24 is provided at the bottom of the hook.

[0037] In this embodiment, the hook and the mounting step are integrally formed to ensure structural strength and reduce assembly steps; the core-pulling hole at the bottom of the hook facilitates demolding during mold manufacturing and does not affect the connection function of the hook. When the hanging hole and the hook are matched, the core-pulling hole will not affect the connection stability.

[0038] Specifically, the taper of the tapered segment is 2-5°.

[0039] In this embodiment, the tapered section with a taper of 2-5° ensures good guidance for the connecting post and connecting hole during installation, allowing the wiring block to be inserted smoothly, and also generates appropriate squeezing and tightening force after installation.

[0040] Specifically, a hanging opening 25 is provided on the back of the bottom shell, and raised steps 26 are provided on both sides of the hanging opening 25.

[0041] In this embodiment, the hanging hole on the back of the shell is used to suspend the electricity meter in a fixed position such as a wall. The raised steps on both sides can create a certain gap between the bottom shell and the mounting surface, so as to avoid the installation stability of the electricity meter being affected by the unevenness of the mounting surface, and at the same time reserve space for operations such as wiring connections.

[0042] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
