Description

Technical Field

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

[0002] Electricity meters are used to measure and record the amount of electricity consumed by households or businesses. They help users understand their electricity usage and provide a basis for electricity bill calculation. During use, the high-voltage current on the user side of the electricity meter is connected through the current terminal. The current sampling circuit on the main board performs real-time measurement and signal conversion. The processed data is transmitted to the signal processing unit through the internal circuit of the main board. Finally, the standardized electrical parameter information is output to the external system through the signal terminal. In the existing technology, the current terminal and the signal terminal are fixed as a whole on the electricity meter housing. If any part of the current terminal or the signal terminal is damaged, the whole unit needs to be replaced, which increases maintenance costs. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defect in the prior art where damage to any part of the current terminal or signal terminal requires the replacement of the entire unit, leading to increased maintenance costs. This invention provides a modular structure for an energy meter in which the current terminal module and the signal terminal module are set separately.

[0004] Therefore, this utility model provides a modular structure for an electricity meter, including a housing and a signal terminal module and a current terminal module disposed within the housing. The signal terminal module and the current terminal module are detachably connected, and the signal terminal module is disposed at the upper end of the current terminal module. Both the signal terminal module and the current terminal module are snapped onto the side wall of the housing. The side wall of the housing is provided with a first elastic buckle that snaps onto the current terminal module and a second elastic buckle that snaps onto the signal terminal module. The first elastic buckle and the second elastic buckle are located on the same elastic bracket.

[0005] Furthermore: the current terminal module is provided with first connecting buckles on both sides that abut against the first elastic buckle, the signal terminal module is provided with second connecting buckles on both sides that abut against the second elastic buckle, and the lower end face of the signal terminal module abuts against the upper end face of the current terminal module.

[0006] Furthermore: the insertion structure between the lower end face of the current terminal module and the inner sidewall of the housing includes at least one extension strip disposed on one side of the current terminal module or the housing and an extension groove disposed on the other side and adapted to the extension strip.

[0007] Furthermore, the inner wall of the housing is also provided with at least one positioning rib for assisting in fixing the current terminal module, and the positioning rib can abut against the lower end face of the current terminal module.

[0008] Furthermore: a first snap-fit ​​structure is provided between the current terminal module and the housing, and a second snap-fit ​​structure is provided between the signal terminal module and the housing. The first snap-fit ​​structure includes a first snap-fit ​​groove provided on both sides of the current terminal module and a first snap-fit ​​block provided on the housing. The second snap-fit ​​structure includes a second snap-fit ​​groove provided on both sides of the current terminal module and a second snap-fit ​​block provided on the housing.

[0009] Furthermore, the first latching block and the second latching block are located on the same vertical line.

[0010] The technical solution of this utility model has the following advantages:

[0011] 1. This utility model provides a modular structure for an electricity meter. The electricity meter includes a housing and a signal terminal module and a current terminal module disposed inside the housing. The current terminal module is connected to high-voltage electricity, and the current sampling circuit on the main board performs real-time measurement and signal conversion. The processed data is transmitted to the signal processing unit through the internal circuit of the main board, and finally the standardized electrical parameter information is output to the external system by the signal terminal. To ensure that the current terminal module and the signal terminal module can be stably fixed on the housing, an elastic bracket is provided on the side wall of the housing. The first elastic buckle and the second elastic buckle are both disposed on the elastic bracket. During installation, the current terminal module is first installed on the housing. During the installation process, the two sides of the current terminal module are aligned with the first elastic buckle, and then the two sides of the current terminal module are pressed down together. The side of the current terminal module will then engage with the first elastic buckle. The signal terminal module is then installed on top of the current terminal module, and the signal terminal module is engaged with the second elastic buckle in the same way. Both the first and second elastic buckles are mounted on the same elastic bracket, ensuring that the sides of the signal terminal module and the current terminal module are aligned during installation, with the lower end of the signal terminal module abutting against the upper end of the current terminal module. This ensures that the left, right, upper, and lower sides of the current terminal module are fixed. After the cover plate is closed, the upper side of the current terminal module is fixed, preventing the wires from loosening due to movement of the signal and current terminal modules during use.

[0029] Example

[0030] This embodiment provides a modular structure for an electricity meter, including a housing 1 and a signal terminal module 2 and a current terminal module 3 disposed within the housing 1. The signal terminal module 2 and the current terminal module 3 are detachably connected, with the signal terminal module 2 positioned above the current terminal module 3. Both the signal terminal module 2 and the current terminal module 3 are snapped onto the side wall of the housing 1. The side wall of the housing 1 is provided with a first elastic buckle 4 that snaps onto the current terminal module 3 and a second elastic buckle 5 that snaps onto the signal terminal module 2. The first elastic buckle 4 and the second elastic buckle 5 are located on the same elastic bracket 6.

[0031] The specific improvements mentioned above are as follows: Figures 1-3As shown, the electricity meter includes a housing 1 and a signal terminal module 2 and a current terminal module 3 disposed inside the housing 1. The current terminal module 3 is connected to high voltage, and the current sampling circuit on the main board performs real-time measurement and signal conversion. The processed data is transmitted to the signal processing unit through the internal circuit of the main board, and finally the standardized electrical parameter information is output to the external system by the signal terminal. To ensure that the current terminal module 3 and the signal terminal module 2 can be stably fixed on the housing 1, an elastic bracket 6 is provided on the side wall of the housing 1. The first elastic buckle 4 and the second elastic buckle 5 are both set on the elastic bracket 6. During installation, the current terminal module 3 is first installed on the housing 1. During the installation process, the two sides of the current terminal module 3 are aligned with the first elastic buckle 4, and then the two sides of the current terminal module 3 are pressed down together. The side will then engage with the first elastic buckle 4, and the signal terminal module 2 will be installed on top of the current terminal module 3. The signal terminal module 2 will be engaged with the second elastic buckle 5 in the same way. The first elastic buckle 4 and the second elastic buckle 5 are both set on the same elastic bracket 6, which ensures that the two sides of the signal terminal module 2 and the current terminal module 3 are aligned during installation, and the lower end face of the signal terminal module 2 abuts against the upper end face of the current terminal module 3. In this way, the left side, right side, upper side and lower side of the current terminal module 3 are fixed. After the cover plate is closed, the upper side of the current terminal module 3 is fixed, preventing the wires from becoming loose due to the shaking of the signal terminal module 2 and the current terminal module 3 during use.

[0032] Based on the above embodiments: the current terminal module 3 is provided with first connecting buckles 31 on both sides that abut against the first elastic buckle 4, the signal terminal module 2 is provided with second connecting buckles 21 on both sides that abut against the second elastic buckle 5, and the lower end face of the signal terminal module 2 abuts against the upper end face of the current terminal module 3.

[0033] The specific improvements mentioned above are as follows: Figures 2-4 , Figure 6 As shown, to ensure the connection between the current terminal module 3 and the elastic bracket 6, a first connecting buckle 31 is provided on the terminal module. Both the first elastic buckle 4 and the first connecting buckle 31 are provided with guide slopes. The guide slopes can effectively guide the first connecting buckle 31 to snap into the lower part of the first elastic buckle 4. Guide slopes are also provided on the second elastic buckle 5 and the second connecting buckle 21. The second connecting buckle 21 is snapped into the lower part of the second elastic buckle 5 and located above the first elastic buckle 4. Therefore, through the cooperative arrangement of the first connecting buckle 31 and the second connecting buckle 21, the signal terminal module 2 and the current terminal module 3 can be effectively connected to the side wall of the housing 1.

[0034] Based on the above embodiments: the insertion structure 7 between the lower end face of the current terminal module 3 and the inner side wall of the housing 1 includes at least one extension strip 71 disposed on one side of the current terminal module 3 or the housing 1 and an extension groove 72 disposed on the other side and adapted to the extension strip 71.

[0035] The specific improvements mentioned above are as follows: Figure 4 , Figure 5 , Figure 7 as well as Figure 8 As shown, in order to ensure that the bottom of the current terminal module 3 is fixed to the housing 1 and to prevent the current terminal module 3 from shaking, an extension strip 71 is provided at the bottom of the housing 1, and an extension groove 72 adapted to the extension strip 71 is provided on the current terminal module 3. When installing the current terminal module 3, the first elastic buckle 4 and the first connecting buckle 31 are connected, so that the extension strip 71 and the extension groove 72 can be naturally adapted, so that the installation of the current terminal module 3 can be quick and efficient.

[0036] Based on the above embodiments: at least one positioning rib 11 for fixing the auxiliary current terminal module 3 is also provided on the inner side wall of the housing 1, and the positioning rib 11 can abut against the lower end face of the current terminal module 3.

[0037] The specific improvements mentioned above are as follows: Figure 8 As shown, a slot is provided below the current terminal module 3. The slot can save some material. In order to increase the connection stability between the current terminal module 3 and the housing 1 and further prevent the current terminal module 3 from shaking, a positioning rib 11 is provided on the housing 1. With the setting of the positioning rib 11, when the current terminal module 3 is installed on the housing 1, the positioning rib 11 can support the current terminal module 3 and effectively prevent it from shaking.

[0038] Based on the above embodiments: a first snap-fit ​​structure 8 is provided between the current terminal module 3 and the housing 1, and a second snap-fit ​​structure 9 is provided between the signal terminal module 2 and the housing 1. The first snap-fit ​​structure 8 includes a first snap-fit ​​groove 81 provided on both sides of the current terminal module 3 and a first snap-fit ​​block 82 provided on the housing 1. The second snap-fit ​​structure 9 includes a second snap-fit ​​groove 91 provided on both sides of the current terminal module 3 and a second snap-fit ​​block 92 provided on the housing 1.

[0039] Based on the above embodiments: the first latching block 82 and the second latching block 92 are located on the same vertical line.

[0040] The specific improvements mentioned above are as follows: Figure 9 as well as Figure 10As shown, the first snap-fit ​​block 82 and the second snap-fit ​​block 92 are both disposed on the housing 1, and the first snap-fit ​​block 82 and the second snap-fit ​​block 92 are located on the same vertical line. When the current terminal module 3 is installed, when the first elastic buckle 4 is snapped with the first connecting buckle 31, the first snap-fit ​​groove 81 will naturally be inserted into the first snap-fit ​​block 82, thereby achieving dual positioning between the housing 1 and the current terminal module 3. Similarly, when the signal terminal module 2 is installed, when the second elastic buckle 5 is snapped with the second connecting buckle 21, the second snap-fit ​​groove 91 will naturally be inserted into the second snap-fit ​​block 92, thereby achieving dual positioning between the housing 1 and the signal terminal module 2.

[0041] 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.
