[0006] In one exemplary embodiment, the elastic portion includes a second bending segment, one end of which is connected to the end of the first bending segment away from the positioning portion, and the second bending segment bends back relative to the first bending segment in a direction closer to the positioning portion; the other end of the second bending segment extends in a direction closer to the bottom shell and is spaced apart from the positioning structure.

[0007] In one exemplary embodiment, the elastic portion includes a third bending segment, one end of which is connected to the end of the second bending segment away from the first bending segment, and the other end of which is bent relative to the second bending segment toward the direction of the bottom shell.

[0008] In an exemplary embodiment, the smart meter further includes: a first limiting structure, comprising two first positioning plates arranged at relative intervals, the first positioning plates being disposed on the bottom shell and located between the conductive sheet and the positioning structure, a first gap being formed between the two first positioning plates, the first gap extending along the direction from the positioning structure to the conductive sheet, the elastic portion passing through the first gap, the elastic portion being capable of elastic deformation along the first gap.

[0029] Figure 1 A cross-sectional view of a smart meter is shown. Figure 2 A structural diagram of conductive wire 4 is shown. Figure 3An exploded view of the structure of a smart meter is shown. Figure 4 A magnified view of a smart meter is shown.

[0030] Reference Figures 1 to 4 The smart meter of this application includes a base shell 1, a relay 2, a positioning structure 3, and a conductive wire 4.

[0031] The bottom shell 1 is provided with a power supply structure 11. The power supply structure 11 is used to obtain power from or disconnect power from the outside.

[0032] The relay 2 includes a main body 21 and a conductive sheet 22. The main body 21 is spaced apart from the bottom shell 1. The conductive sheet 22 is disposed on the main body 21 and inserted into the bottom shell 1. The conductive sheet 22 is spaced apart from the power taking structure 11.

[0033] The positioning structure 3 is disposed on the bottom shell 1, and the positioning structure 3 is located between the conductive sheet 22 and the power taking structure 11.

[0034] The conductive wire 4 is located between the bottom shell 1 and the main body 21. The conductive wire 4 includes a connecting part 43, a positioning part 41, and an elastic part 42 arranged sequentially along its extension direction. The connecting part 43 is used to conductively connect to the power-taking structure 11. The positioning part 41 is detachably positioned on the positioning structure 3. The elastic part 42 can elastically swing relative to the positioning part 41, so that the elastic part 42 can deform and abut against the conductive sheet 22 as the conductive sheet 22 is inserted.

[0035] In this application, the connecting portion 43 and the positioning portion 41 of the conductive wire 4 are respectively disposed at both ends of the elastic portion 42. The conductive wire 4 is fixed to the base by being positioned on the positioning structure 3 by the positioning portion 41. The connecting portion 43 can electrically connect to the power-taking structure 11. The elastic portion 42 can abut against the conductive sheet 22 by elastically deforming relative to the positioning portion 41, thereby realizing the power taking of the conductive sheet 22. The elastic portion 42 of the conductive wire 4 has good elastic deformation capability. The elastic portion 42 automatically compensates for the contact pressure with the conductive sheet 22, thereby ensuring the reliability of the power taking connection between the elastic portion 42 and the conductive sheet 22 and improving the power taking stability.

[0036] The conductive wire 4 simultaneously performs the dual functions of mechanical elasticity and voltage conduction. The elastic deformation of the elastic part 42 can compensate for material manufacturing tolerances, enabling adaptive compensation of the conductive connection between the elastic part 42 and the conductive sheet 22, thereby improving production efficiency. Furthermore, the positioning part 41 is detachably positioned on the positioning structure 3, allowing the conductive wire 4 to be positioned on the base without welding to complete power extraction. This not only reduces the amount of welding required and improves production efficiency but also facilitates the reuse or replacement of the conductive wire 4.

[0037] like Figure 1 and Figure 3 As shown, the bottom shell 1 is spaced apart on the bottom side of the main body 21. The power-collecting structure 11 on the bottom shell 1 includes a power-collecting nut 111 and a screw 112. The power-collecting nut 111 is inserted through the bottom shell 1 and has an axial through-hole. The power-collecting nut 111 is used to draw power from or disconnect power from the outside. The end of the connecting part 43 away from the positioning part 41 is locked inside the power-collecting nut 111 by the mounting screw 112, realizing a conductive connection with the power-collecting nut 111. The power-collecting nut 111 can be a copper nut.

[0038] The bottom shell 1 is also provided with a slot 12 for inserting the conductive sheet 22. The slot 12 is spaced apart from the power-taking structure 11, and the slot 12 and the power-taking structure 11 are located on opposite sides of the positioning structure 3.

[0039] Furthermore, the conductive sheet 22 includes an abutting section 221 and an insertion section 222 connected sequentially to the bottom side. The abutting section 221 abuts against the elastic part 42. The insertion section 222 is bent relative to the abutting section 221 in a direction away from the positioning structure 3 to form a stepped structure, so that the insertion section 222 is spaced apart from the elastic part 42. The bottom of the insertion section 222 is inserted into the slot 12.

[0040] Specifically, the conductive sheet 22 has an insertion direction from top to bottom. The abutting section 221 and the insertion section 222 are connected sequentially towards the bottom. The conductive sheet 22 forms a bent step structure at the junction of the abutting section 221 and the insertion section 222. The step surface of the insertion section 222 is further away from the elastic part 42 than the step surface of the abutting section 221, so that the elastic part 42 is located within the insertion trajectory of the abutting section 221, but offset from the insertion trajectory of the insertion section 222. When the conductive sheet 22 moves towards the slot 12 along the insertion direction, the insertion section 222 does not contact the elastic part 42, thus not hindering the assembly of the relay 2. When the conductive sheet 22 is about to be inserted, the abutting section 221 will contact the elastic part 42. At this time, the conductive sheet 22 is inserted into the slot 12 without being bounced off, and the elastic part 42 can maintain its abutment against the abutting section 221, ensuring reliable power connection.

[0041] In this embodiment, the conductive sheet 22 is an input copper sheet.

[0042] In this embodiment, the positioning structure 3 is disposed on the top of the bottom shell 1 and located between the bottom shell 1 and the main body 21. The positioning part 41 of the conductive wire 4 is detachably positioned on the positioning structure 3.

[0043] Furthermore, the positioning structure 3 is provided with a positioning hole 31, and the positioning part 41 includes a first positioning segment 411, which is housed in the positioning hole 31. One end of the first positioning segment 411 extends to the outside of the positioning hole 31 and is connected to the elastic part 42.

[0044] The first positioning segment 411 extends into and is housed within the positioning hole 31, allowing the inner wall of the positioning hole 31 to restrict the movement of the first positioning segment 411, thereby achieving overall positioning of the conductive wire 4. Furthermore, the first positioning segment 411 housed within the positioning hole 31 provides the elastic part 42 with an elastic arm of a defined length, improving the certainty of the elastic swing process of the elastic part 42. In this embodiment, the positioning hole 31 is located at the top of the positioning structure 3.

[0045] Combination Figure 1 and Figure 2 The first positioning segment 411 is U-shaped. The U-shaped opening of the first positioning segment 411 faces the same direction as the opening of the positioning hole 31. One end of the first positioning segment 411 extends out of the opening of the positioning hole 31 and connects with the elastic part 42.

[0046] In some other embodiments, the opening of the positioning hole 31 may also be provided on the side wall of the positioning structure 3, and the conductive wire 4 includes a positioning part 41 protruding toward the positioning hole 31 so that the positioning part 41 can be accommodated in the positioning hole 31.

[0047] In addition, the first positioning segment 411 can also be in other shapes such as a V-shape that protrude in the direction of the positioning hole 31.

[0048] In some other embodiments, the positioning structure 3 may also be provided with a slot, and the positioning part 41 is engaged in the slot along the extension direction of the slot to realize the positioning of the positioning part 41.

[0049] To further position the conductive wire 4 between the bottom shell 1 and the main body 21, in this embodiment, a third gap 32 is formed between the bottom of the main body 21 and the positioning structure 3, and the third gap 32 extends along the direction from the positioning structure 3 to the power-taking structure 11. Furthermore, the positioning part 41 includes a second positioning segment 412. One end of the first positioning segment 411, away from the elastic part 42, extends to the outside of the positioning hole 31 and connects to one end of the second positioning segment 412. The second positioning segment 412 passes through the third gap 32, and the other end of the second positioning segment 412 is connected to the connecting part 43.

[0050] The bottom of the main body 21 forms the inner top wall of the third slit 32, and the top surface of the positioning structure 3 forms the inner bottom wall of the third slit 32. The second positioning segment 412 passes through the third slit 32. As the main body 21 of the relay 2 moves towards the bottom and drives the conductive sheet 22 to be inserted into the bottom shell 1, the distance between the inner top wall and the inner bottom wall of the third slit 32 gradually decreases. After the conductive sheet 22 is inserted, the second positioning segment 412 can be limited within the smaller distance of the third slit 32. In this embodiment, by limiting the movement of the second positioning segment 412 along the direction between the bottom and the top, the position of the conductive wire 4 between the bottom shell 1 and the main body 21 is limited, further ensuring that the elastic part 42 can stably abut against the conductive sheet 22, thereby improving the reliability of power extraction.

[0051] In this embodiment, the opening of the positioning hole 31 faces the main body 21. After the first positioning segment 411 is engaged in the positioning hole 31, the positioning hole 31 can restrict the movement of the conductive wire 4 between the conductive sheet 22 and the power-taking structure 11, so that the fulcrum position of the elastic part 42 relative to the positioning part 41 is determined, ensuring that the elastic part 42 is stably held against the conductive sheet 22, further improving the reliability of power taking. At the same time, the third gap 32 can restrict the movement of the conductive wire 4 between the main body 21 and the bottom shell 1, further completing the spatial positioning of the conductive wire 4, reducing the phenomenon of misalignment of the conductive wire 4 in various directions during the power taking process, and improving the reliability of power taking.

[0052] In this application, the elastic portion 42 of the conductive wire 4 can elastically swing relative to the positioning portion 41. Specifically, the elastic portion 42 can elastically swing relative to the positioning portion 41 between the conductive sheet 22 and the power-taking structure 11. Alternatively, the elastic portion 42 can elastically swing relative to the positioning portion 41 between the conductive sheet 22 and the power-taking structure 11, and also between the main body 21 and the bottom shell 1.

[0053] Specifically, the elastic part 42 includes a first bending section 421. One end of the first bending section 421 is connected to the positioning part 41 and extends toward the conductive sheet 22. The first bending section 421 is bent obliquely toward the bottom shell 1 relative to the positioning part 41. The other end of the first bending section 421 is used to abut against the conductive sheet 22.

[0054] like Figure 1As shown, the first bent segment 421 is bent obliquely towards the bottom shell 1 and towards the conductive sheet 22 via the relative positioning part 41, so that the end of the first bent segment 421 away from the positioning part 41 can extend into the insertion trajectory of the conductive sheet 22. When the relay 2 is installed, the end of the first bent segment 421 away from the positioning part 41 can elastically deform relative to the positioning part 41 as the conductive sheet 22 is inserted. That is, the first bent segment 421 will be squeezed by the conductive sheet 22 and elastically swing away from the conductive sheet 22, and elastically swing relative to the positioning part 41 towards the bottom shell 1, so that the end of the first bent segment 421 away from the positioning part 41 can avoid the insertion trajectory of the conductive sheet 22 and maintain contact with the conductive sheet 22 under the squeezing of the conductive sheet 22.

[0055] Furthermore, the elastic portion 42 includes a second bent section 422, one end of which is connected to the end of the first bent section 421 away from the positioning portion 41. The second bent section 422 bends back relative to the first bent section 421 in a direction closer to the positioning portion 41. The position where the first bent section 421 and the second bent section 422 are connected is used to abut against the conductive sheet 22. By bending the second bent section 422 back relative to the first bent section 421, direct contact between the end of the conductive wire 4 and the conductive sheet 22 is avoided, reducing frictional damage at the point where the elastic portion 42 abuts against the conductive sheet 22.

[0056] Specifically, the first bending segment 421 and the second bending segment 422 are connected in an arc shape to reduce sharp structures and further reduce frictional damage at the point where the elastic part 42 abuts against the conductive sheet 22.

[0057] Furthermore, the other end of the second bent section 422 is spaced apart from the positioning structure 3 to avoid affecting the first bent section 421 when the conductive sheet 22 is inserted and causing pressure deformation.

[0058] Furthermore, the other end of the second bent segment 422 extends towards the bottom shell 1. Specifically, by bending the second bent segment 422 relative to the first bent segment 421 towards the bottom shell 1, after the first bent segment 421 is squeezed by the conductive sheet 22, the first bent segment 421 will drive the second bent segment 422 to move towards the positioning structure 3. By designing the second bent segment 422 to extend towards the bottom, not only can the frictional damage caused to the outer wall of the positioning structure 3 by the end of the second bent segment 422 away from the first bent segment 421 be reduced, but also the phenomenon of deformation and jamming of the first bent segment 421 caused by the contact between the second bent segment 422 and the positioning structure 3 can be reduced.

[0059] Furthermore, the elastic portion 42 includes a third bending segment 423, one end of which is connected to the end of the second bending segment 422 away from the first bending segment 421, and the other end of which is bent relative to the second bending segment 422 toward the direction of the bottom shell 1.

[0060] Specifically, the second bending segment 422 bends obliquely towards the bottom shell 1 relative to the first bending segment 421, and the third bending segment 423 bends again towards the bottom shell 1 relative to the second bending segment 422. This further reduces frictional damage to the outer wall of the positioning structure 3 caused by the end of the second bending segment 422 away from the first bending segment 421, and further reduces the phenomenon of deformation and jamming of the first bending segment 421 due to contact between the second bending segment 422 and the positioning structure 3. In this application, the second bending segment 422 and the third bending segment 423 are connected by an arc shape, reducing sharp structures and further reducing frictional damage caused when the second bending segment 422 abuts against the positioning structure 3.

[0061] Combination Figure 1 , Figure 2 and Figure 4 The smart meter of this application further includes a first limiting structure 5. The first limiting structure 5 includes two relatively spaced first positioning plates 51, which are disposed on the bottom shell 1 and located between the conductive sheet 22 and the positioning structure 3. A first gap 52 is formed between the two first positioning plates 51, extending along the direction from the positioning structure 3 to the conductive sheet 22. The elastic part 42 passes through the first gap 52 and can elastically deform along the first gap 52.

[0062] The first slit 52 can support the opposite sides of the elastic part 42, thereby limiting the directional deformation of the elastic part 42, so that the conductive sheet 22 can be installed smoothly and the elastic part 42 can be stably held against the conductive sheet 22.

[0063] It should be noted that the gap between the inner walls of the opposite sides of the first slit 52 and the elastic part 42 is provided to ensure that the elastic part 42 can elastically swing relative to the positioning part 41. In addition, the side of the elastic part 42 away from the positioning part 41 needs to extend out of the first slit 52 to ensure that the elastic part 42 can contact the conductive sheet 22.

[0064] In this application, the connecting portion 43 of the conductive wire 4 is connected to the end of the positioning portion 41 away from the elastic portion 42. The connecting portion 43 extends from the positioning structure 3 toward the power-taking structure 11, and the end of the connecting portion 43 away from the positioning portion 41 is electrically connected to the power-taking structure 11.

[0065] The smart meter of this application also includes a second limiting structure 6.

[0066] The second limiting structure 6 includes two relatively spaced second positioning plates 61. The second positioning plates 61 are disposed on the bottom shell 1 and located between the positioning structure 3 and the power taking structure 11. A second gap 62 is formed between the two second positioning plates 61. The second gap 62 extends along the direction of the positioning structure 3 and the power taking structure 11. The connecting part 43 passes through the second gap 62.

[0067] The extension direction of the second slit 62 is the same as that of the connecting part 43, so that the connecting part 43 can be accommodated in the second slit 62, further improving the installation stability of the conductive wire 4.

[0068] Furthermore, the connecting portion 43 extends relative to the positioning portion 41 towards the inner bottom of the second slot 62. The connecting portion 43 can be supported by the inner bottom of the second slot 62, reducing the shaking of the connecting portion 43.

[0069] like Figure 2 and Figure 4 As shown, the connecting part 43 includes an extension section 431, a third positioning section 432, and a power-taking section 433 connected in sequence.

[0070] One end of the extension section 431 is connected to the second positioning section 412 of the positioning part 41, and the other end of the extension section 431 extends towards the bottom shell 1 to the inner bottom of the second gap 62 and connects to one end of the third positioning section 432. The third positioning section 432 fits against the inner bottom of the second gap 62 and extends along the extension direction of the second gap 62 to the position of the power-taking nut 111. One end of the power-taking section 433 is connected to the other end of the third positioning section 432, and the power-taking section 433 is embedded inside the power-taking nut 111 and locked inside the power-taking nut 111 by the screw 112. The top of the second positioning section 412 can be limited by the bottom of the main body 21, and the bottom of the third positioning section 432 can be limited by the inner bottom of the second gap 62, so that the position of the conductive wire 4 in the positioning part 41 and the connecting part 43 can be constrained in the top and bottom directions, further improving the positioning stability of the conductive wire 4.

[0071] Furthermore, the connecting portion 43 can adjust its shape according to the conductive position of the conductive wire 4 between the conductive sheet 22 and the power-collecting structure 11, such as by bending it in different directions, to ensure that the conductive wire 4 can electrically connect the conductive sheet 22 and the power-collecting structure 11. In this embodiment, the conductive position of the conductive wire 4 between the conductive sheet 22 and the power-collecting structure 11 has a drop from top to bottom, thereby extending the connecting portion 43 towards the bottom. In addition, in some embodiments, this can also be achieved by setting the position of the positioning portion 41 at a lower position.

[0072] In this embodiment, the elastic portion 42, the positioning portion 41, and the connecting portion 43 of the conductive wire 4 are connected sequentially in a strip shape. The structures of the positioning portion 41 and the elastic portion 42 are on the same plane. Furthermore, Figure 2 The extension 431 and the third positioning section 432 of the connecting part 43 shown are also on the same plane as the positioning part 41. The conductive wire 4 is elastic and conductive as a whole, and can be formed by bending steel wire, resulting in low production cost. In addition, the surfaces of the conductive sheet 22 and the conductive wire 4 can be nickel-plated, which can effectively prevent corrosion and ensure long-term reliable contact between the two.

[0073] The positioning structure 3, the first limiting structure 5, and the second limiting structure 6 of this application can be detachably installed with the bottom shell 1 or integrally formed with the bottom shell 1. The first limiting structure 5, the positioning structure 3, and the second limiting structure 6 are connected sequentially along the direction from the conductive sheet 22 to the power taking structure 11, making the positions of the first gap 52, the positioning hole 31, and the third gap 32 more compact, which can correspond to the positioning elastic part 42, the positioning part 41, and the connecting part 43, further improving the positioning and installation stability of the conductive wire 4.
