Description

Technical Field

[0001] This utility model relates to the field of electricity meter technology, and in particular to a conveniently expandable electricity meter structure and an electricity meter group having the same. Background Technology

[0002] As smart grids place increasing demands on the functional expandability of electricity meters, single-meter expansion or multi-meter splicing has become the main method for realizing additional functions. The expansion connection structure needs to meet requirements such as long-term stable fixation and easy protection in non-expanded states. Existing electricity meters and expansion modules mostly use plastic clips for quick connection. While this simplifies installation, the plastic material is difficult to adapt to the operating environment and lifespan requirements. In outdoor environments and distribution boxes, temperature differences cause repeated thermal expansion and contraction of the clips, and strong ultraviolet radiation accelerates aging and embrittlement, leading to deformation, breakage, loose connections, poor electrical contact, or even detachment. Furthermore, the mechanical performance of the plastic clips degrades much faster than the lifespan of the electricity meter, becoming a weakness in the expansion structure and increasing maintenance costs.

[0003] To address the shortcomings of plastic clips, some existing electricity meters use detachable connectors for extended fixation. However, problems still exist. Most detachable connectors lack precise pre-positioning design, requiring repeated adjustments to the relative positions of the electricity meters during assembly to align the connectors with the mounting holes, significantly reducing on-site assembly efficiency. Summary of the Invention

[0004] To address the aforementioned problems, this utility model provides a conveniently expandable energy meter structure and an energy meter assembly incorporating the same.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. 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.

[0024] like Figure 1 , Figure 2 This application provides a conveniently expandable electricity meter structure, including a housing 10 that carries internal components, and an execution unit, a display unit 100, and a processing unit disposed within the housing 10. The back of the housing 10 protrudes outward to form a fixing seat 11, which is located in the middle of the rear of the housing 10. The execution unit is responsible for the core execution operation of electricity metering, the display unit 100 is used for the visualization of data information, and the processing unit undertakes the functions of information calculation, processing, and control.

[0025] like Figure 3 As shown, a first insert 20 protruding outward is provided on one side of the housing 10. Correspondingly, the housing 10 is provided with a receiving groove 21 that is adapted to the first insert 20, and the first insert 20 and the housing 10 are connected by a rotating shaft 22. The rotating shaft 22 is designed so that the first insert 20 can rotate around the rotating shaft 22 as the central axis. When no expansion connection is needed, the first insert 20 can be rotated and stored in the receiving groove 21, which avoids damage caused by exposed parts and ensures the regularity of the overall structure of the housing 10.

[0026] On the other side of the housing 10 opposite to the first insert 20, there is an inwardly recessed first insertion groove 30. The size of the first insertion groove 30 matches the first insert 20 and is used to accommodate the first insert 20 of the adjacent electricity meter to form a mating connection.

[0027] To achieve positioning and stable fixation, a first positioning hole 23 is provided on the first insert 20; at the same time, a second positioning hole 31 is provided at the corresponding position on the inner wall of the first insert groove 30, and the second positioning hole 31 is provided through the housing 10. The opening direction of the first positioning hole 23 and the second positioning hole 31 is consistent to ensure that the two can be accurately aligned.

[0028] When it is necessary to expand the assembly of two adjacent electricity meters, the operation process is as follows: rotate the first insert 20 of one electricity meter out of its receiving groove 21, and then insert it into the first insert groove 30 of the other electricity meter. At this time, the corresponding first positioning hole 23 and second positioning hole 31 on the two electricity meters will naturally align. Finally, insert the pin into the two aligned positioning holes to complete the stable connection of the two electricity meters and realize convenient expansion.

[0029] First positioning blocks 24 are provided on both sides of the first insert 20. The first positioning blocks 24 are hemispherical with smooth transition of their arc surfaces. First positioning grooves 25 are provided on both sides of the receiving groove 21. The first positioning grooves 25 are also hemispherical, and their curvature and size are perfectly matched with the first positioning blocks 24, forming a mating structure.

[0030] When the first insert 20 is inserted into the receiving groove 21, the hemispherical first positioning blocks 24 on both sides of the first insert 20 will naturally align with and embed into the hemispherical first positioning grooves 25 on both sides of the receiving groove 21. Through this shape matching method, the first insert 20 will not rotate out of the receiving groove 21 due to shaking after entering the receiving groove 21.

[0031] To further optimize the ease of operation of the first insert 20, a recessed finger groove 26 is provided at the position of the housing 10 adjacent to the receiving groove 21. The partial recessed design of the finger groove 26 on the surface of the housing 10 ensures that the finger can be naturally inserted for operation. The position of the finger groove 26 corresponds to the state of the first insert 20 after it is stored. When the first insert 20 is rotated and stored in the receiving groove 21, the area of ​​the housing 10 covered by the finger groove 26 corresponds exactly to the edge or part of the surface of the first insert 20, so that the first insert 20 can be partially exposed through the recessed space of the finger groove 26 in the stored state for convenient operation.

[0032] like Figure 4 and Figure 5The first insert 20 and the first insertion slot 30 shown are both positioned close to the front surface of the housing 10. The front surface of the housing 10 is the operation and display area of ​​the energy meter. A connecting component is provided on the rear surface of the housing 10 opposite to the front surface. The function of the connecting component is similar to that of the first insert 20 and the first insertion slot 30 on the front surface, and it is also used for the extended connection of two adjacent energy meters. Through the cooperation of the connecting component on the rear surface, the overall stability of the connection between adjacent energy meters is further enhanced, and the robustness of the structure after the extended assembly is ensured.

[0033] like Figure 6 The connection assembly shown includes a first connector 40 fixed to the rear surface of the housing 10 and a second connector 50 also fixed to the rear surface of the housing 10. The two cooperate with each other to achieve the connection of the rear surfaces of adjacent energy meters.

[0034] The first connector 40 and the housing 10 form a receiving groove 41, the size and shape of which are adapted to accommodate the second insert 42. A movable second insert 42 is disposed inside the receiving groove 41. The second insert 42 and the receiving groove 41 are designed to slide together, allowing the second insert 42 to slide freely along the extension direction of the receiving groove 41. In the non-expanded state, it can be completely retracted into the receiving groove 41 to avoid exposure; when expansion is required, it can slide out from the receiving groove 41 to achieve the connection function. The second connector 50 and the housing 10 form a second insertion groove 51, the size and shape of which are adapted to the second insert 42, for accommodating the second insert 42 of an adjacent energy meter, forming a mating structure for rear surface connection.

[0035] A third positioning hole 43 is provided on the second insert 42; at the same time, a fourth positioning hole 52 is provided at the corresponding position on the inner wall of the second insertion groove 51, and the fourth positioning hole 52 penetrates the second connector 50. The opening direction of the third positioning hole 43 and the fourth positioning hole 52 is consistent to ensure that the two can be aligned.

[0036] When two adjacent electricity meters are being extended and assembled, the second insert 42 of one electricity meter is slid out of its receiving slot 41 and then inserted into the second insert slot 51 of the other electricity meter. At this time, the corresponding third positioning hole 43 and fourth positioning hole 52 on the two electricity meters will naturally align. Finally, the pin is inserted into the aligned positioning hole to complete the stable connection of the finished surface, which together with the insertion structure of the front surface forms a complete extension fixation.

[0037] A sliding groove 44 adapted to the sliding direction of the second insert 42 is provided on the first connector 40, and a pusher 45 is fixedly provided on the second insert 42; the pusher 45 protrudes upward, one end of which is firmly connected to the surface of the second insert 42, and the other end extends toward the sliding groove 44 and can pass through the sliding groove 44 on the first connector 40, and after passing through, it will protrude from the surface of the second connector 50, and its protrusion height is so that the operator's fingertips can easily touch and slide.

[0038] When the second insert 42 needs to be moved, simply operate the pusher 45 with your finger and push it along the extension direction of the sliding groove 44. The pusher 45 will move along the trajectory of the sliding groove 44, and at the same time drive the second insert 42 to slide synchronously in the storage groove 41, so that the second insert 42 slides out of the storage groove 41. In the non-expanded state, the second insert 42 slides back into the storage groove 41 for storage.

[0039] A second positioning block 46 and a third positioning block 47 are provided on both sides of the second insert 42. Both are hemispherical in shape and are arranged sequentially according to the movement direction of the second insert 42, maintaining a fixed distance. A hemispherical second positioning groove is provided on both sides of the receiving groove 41 and is fully adapted to the second positioning block 46 and the third positioning block 47. When the second insert 42 is in the receiving state, the second positioning block 46 and the second positioning groove are positioned to prevent the second insert 42 from sliding out of the receiving groove 21. When the second insert 42 is in the extended state, the third positioning block 47 and the second positioning groove are positioned to provide positioning for the subsequent precise alignment of the third positioning hole 43 and the fourth positioning hole 52.

[0040] The connecting components are disposed on the upper and lower parts of the housing 10; so that when two adjacent energy meters are connected through the rear surface, the upper and lower connecting components are simultaneously subjected to force and are fixed together, avoiding the problem of uneven force caused by single-point or single-sided connection, and further enhancing the stability of the rear surface connection.

[0041] An electricity meter group includes at least two electricity meters as described above, which can be flexibly configured to two, three or more according to actual functional expansion needs, and the connection between two adjacent electricity meters is fully implemented using the above-described electricity meter structure.

[0042] The electricity meter structure and electricity meter group of this application, through the pre-positioning of the hemispherical positioning block and the positioning groove, and the insertion and fixing of the pin, avoids loosening of the connection and ensures the structural stability and electrical contact reliability of long-term use; the first insert 20 can be easily operated with the finger groove 26, and the pusher 45 can easily drive the second insert 42 to slide, significantly improving assembly efficiency; the first insert 20 can be stored in the receiving groove 21, and the second insert 42 can be stored in the receiving groove 41, avoiding damage to exposed parts or contamination with impurities, and enhancing protection performance; the electricity meter group can flexibly contain at least two electricity meters, and the number can be increased or decreased according to needs to achieve multi-meter collaboration, adapting to the functional expansion needs of different scenarios such as residential electricity consumption and industrial monitoring under the smart grid, while avoiding the problem of easy aging and brittleness of traditional plastic buckles, improving overall durability and reducing later maintenance costs.

[0043] It should be emphasized that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
