Technical Field

[0001] The utility model relates to the technical field of electric energy meter bases, in particular to a single-phase intelligent electric energy meter base. Background Art

[0002] With the digital transformation of the power industry and the development of smart grids, smart energy meters, as key infrastructure of smart grids, have been widely used in power user metering and management. They provide data collection, processing, and transmission functions, and interact with user terminal devices to achieve remote monitoring, data analysis, and intelligent control. For example, the Chinese patent for a single-phase smart energy meter base, published as Publication No. CN210222101U, states that when installing the energy meter, simply install the meter along the positioning frame on the base plate, eliminating the need for fixing screws and reducing wiring errors. Secondly, before replacing the meter, the phase and neutral input and output terminals on the terminal block are short-circuited, making the operation simple, convenient, and efficient. Third, the entire energy meter replacement process does not affect the user's power supply, solving the technical problem of power outages required for meter replacement. However, the phase input, neutral input, phase output, and neutral output terminals on the energy meter base are fixed. This requires different energy meters to be configured with a suitable energy meter base, making it incompatible with meters of different models or specifications, limiting the universality of the energy meter base. To this end, the utility model proposes a one-way smart electric energy meter base. Utility Model Content

[0003] The purpose of the present utility model is to address the problem in the background technology that the phase line input terminal, neutral line input terminal, phase line output terminal and neutral line output terminal of the electric energy meter base are all fixed settings, which results in different electric energy meters needing to be configured with adapted electric energy meter bases, and cannot adapt to electric energy meters of different models or specifications, limiting the versatility of the electric energy meter base. A single-phase intelligent electric energy meter base is proposed.

[0004] The technical solution of the present utility model is as follows: a single-phase smart electricity meter base, comprising: a bottom plate, a fixing frame is fixedly provided on one side of the bottom plate, and a plurality of first through holes are provided on the bottom of the fixing frame; a fixing plate is provided between the fixing frames, a plurality of second through holes are provided on the fixing plate, a connecting terminal is movably sleeved inside the second through holes, and one end of the connecting terminal is fixedly connected to the wire terminal; a fixing block is located between the fixing frames, a plurality of grooves are provided on one side of the fixing block, and two groups of slide grooves are respectively provided on the inner walls of the grooves, a slider is slidingly provided inside the slide groove, and a connecting component for adjusting the movement of the connecting terminal is fixedly provided between the sliders; an adjusting component is fixedly provided on one side of the fixing block for limiting the connecting component.

[0006] Optionally, the adjustment component includes a limit plate fixedly arranged between the first through holes, a plurality of third through slots are fixedly opened on the limit plate, a threaded rod is movably sleeved inside the third through slot, one end of the threaded rod is threadedly connected to the connecting block, and the other end of the threaded rod is threadedly sleeved with a threaded cap.

[0007] Optionally, a guide groove is provided on an inner wall of the second through hole, and a guide block is fixedly provided on an outer wall of the connecting terminal, and the guide block is slidably connected to the guide groove.

[0008] Optionally, an insulating ring is fixedly sleeved on the outer wall of the connecting terminal.

A connecting terminal 6 is movably sleeved inside the second through hole 5, which can guide the connecting terminal 6 and make the horizontal movement of the connecting terminal 6 more stable. One end of the connecting terminal 6 is fixedly connected with a wire terminal 7, and the wire terminal 7 is arranged with a 90-degree bend; a fixing block 8 located between the fixing frames 2, a plurality of grooves 9 are opened on one side of the fixing block 8, two groups of sliding grooves 10 are respectively opened on the inner wall of the groove 9, and the sliding grooves 10 are symmetrically arranged. A slider 11 is slidably arranged inside the sliding groove 10, and a connecting component 12 for adjusting the movement of the connecting terminal 6 is fixedly arranged between the sliders 11, which can guide the connecting component 12 and make the horizontal movement of the connecting component 12 more stable; an adjusting component 13 fixedly arranged on one side of the fixing block 8 for limiting the connecting component 12, which can conveniently adjust the position of the connecting component 12, thereby driving the connecting terminal 6 to adjust the position and improving the applicability.

[0027] As Figure 2 and Figure 3 shown, the connecting component 12 includes a connecting block 121, and the connecting block 121 is located on the inner wall of the groove 9. A connecting through hole 122 is opened on one side of the connecting block 121, and the connecting through hole 122 is communicated with the first through hole 3, which is convenient for the connection of the cable. A clamping groove 123 is opened on the inner wall of the connecting through hole 122, and the clamping groove 123 is movably inserted with the wire terminal 7, which is convenient for the connecting block 121 to drive the wire terminal 7 to move horizontally. Two threaded through holes 124 are opened on one side of the connecting block 121, and the threaded through holes 124 are communicated with the connecting through hole 122, which is convenient for positioning the cable through bolts. Springs 125 are respectively fixedly arranged on both sides of the connecting block 121, and one end of the spring 125 is fixedly connected with the fixing block 8, which improves the stability of the horizontal movement of the connecting block 121.

[0028] As Figure 2 and Figure 3As shown, the adjustment component 13 includes a limit plate 131 fixedly arranged between the first through holes 3, and the limit plate 131 is located directly above the connecting block 121. A plurality of third through slots 132 are fixedly provided on the limit plate 131. A threaded rod 133 is movably sleeved inside the third through slot 132. One end of the threaded rod 133 is threadedly connected to the connecting block 121 to facilitate driving the connecting block 121 to move horizontally, thereby adjusting the position of the connecting terminal 6.
