Description

Technical Field

[0001] This utility model relates to the field of parts processing technology, and in particular to a clamping device and welding equipment. Background Technology

[0002] The manufacturing process of smart meters involves welding the wiring terminals to the terminal block. To ensure a good welding result, the ends of the terminal block and the terminals must maintain stable contact during welding. Related technologies use clamping devices to fix the terminals and terminal blocks. To ensure that the ends of the terminals can reliably overlap the ends of the terminal blocks for welding, the clamping device clamps and fixes the terminal block in at least two of the three directions: up / down, left / right, and front / back. In these related technologies, each clamping direction requires a drive source to move a clamping component, resulting in high cost and large size.

[0003] Therefore, there is an urgent need for a clamping device and welding equipment to solve the above-mentioned technical problems. Utility Model Content

[0004] One objective of this invention is to provide a clamping device that can achieve clamping drive of the terminal block in two directions through a single drive source, with a compact structure and low cost.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A clamping device includes a first clamping mechanism for clamping a terminal block. The first clamping mechanism includes a first limiting component, a first driving component, a first pressing member, a lever component, and a first elastic member. The first limiting component supports the terminal block in a first direction and stops the terminal block in a second direction. The first pressing member is connected to the output end of the first driving component. The lever component is pivotally connected to the first pressing member. The first elastic member is disposed between the first pressing member and the lever component. When the lever component is in a first posture, the lower pressing surface of the lever component near the first limiting component is lower than the upper surface of the terminal block located on the first limiting component. The first driving component can drive the first pressing member to move in the second direction to press the terminal block against the first limiting component in the second direction, and force the lever component to rotate to a second posture, in which the lower pressing surface presses the terminal block against the first limiting component in the first direction in the second posture.

[0007] As an optional solution, the lever assembly includes:

[0008] A lever body, which is pivotally connected to the first pressing member;

[0009] A roller and a roller shaft are provided, wherein the roller is rotatably mounted on one end of the lever body near the first limiting component via the roller shaft, and a portion of the circumferential surface of the roller forms the lower pressing surface.

[0010] As an alternative, the middle part of the lever assembly is pivotally connected to the first pressing member via a pivot shaft, and the first elastic member connects the first pressing member and the end of the lever assembly away from the first limiting member.

[0011] As an alternative, the first limiting component can also stop the terminal block in a third direction. The first clamping mechanism further includes a second driving component and a second pressing member. The second pressing member is connected to the output end of the second driving component. The second driving component is used to drive the second pressing member in a third direction so that the second pressing member presses the terminal block against the first limiting component in a third direction.

[0012] As an optional solution, the first limiting component includes:

[0013] Support member for supporting the terminal block along a first direction;

[0014] A first stop is disposed on one side of the support member along the second direction. The height of the first stop member along the first direction is higher than that of the support member, so as to be able to stop the terminal block along the second direction.

[0015] The second stop is disposed on one side of the support member along the third direction, and is used to stop the terminal block along the third direction. The support member is provided with a through hole extending along the third direction, and the second pressing member passes through the through hole so as to press the terminal block along the third direction.

[0016] As an optional embodiment, the clamping device further includes a second clamping mechanism for clamping the terminal block, the second clamping mechanism comprising:

[0017] The second limiting component is provided with a limiting groove, which can limit the terminal block in a third direction;

[0018] A limiting post protrudes from the inner wall of the limiting groove perpendicular to the first direction, and the limiting post is used to pass through the mounting hole on the terminal block;

[0019] A push plate, wherein the push plate is slidably engaged with the second limiting component along a second direction;

[0020] The third drive assembly is connected to the push plate and is used to drive the push plate to move in the second direction so that the push plate presses the terminal block against the limiting post in the second direction.

[0021] As an optional solution, the third drive assembly includes a cam and a second elastic element. The cam is rotatable relative to the second limiting assembly. The second elastic element connects the second limiting assembly and the push plate and is used to keep the push plate abutting against the cam surface of the cam. The cam is used to drive the push plate to press against the terminal block in a second direction.

[0022] As an optional solution, the second limiting component includes:

[0023] The U-shaped component is arranged to form the limiting groove;

[0024] A sliding guide is connected to the U-shaped component and extends along a third direction. The sliding guide protrudes from the U-shaped component along the third direction. The push plate is in concave-convex engagement with the sliding guide and is slidably connected.

[0025] As an alternative, the clamping device further includes a support mechanism, on which both the first clamping mechanism and the second clamping mechanism are mounted, such that the end of the terminal block held by the first clamping mechanism overlaps with the end of the terminal held by the second clamping mechanism in a first direction.

[0026] Another objective of this invention is to provide a welding device that, by employing the aforementioned clamping device, can reliably fix the terminal block to be welded, and has a compact structure and low cost.

[0027] To achieve this objective, the present invention adopts the following technical solution:

[0028] Welding equipment includes a welding device and the clamping device, wherein the welding device is used to weld the terminal block on the clamping device.

[0029] The beneficial effects of this utility model are:

[0030] In this invention's clamping device, when the connector plate is placed on the first clamping mechanism, the first plate body of the connector plate is supported on the first limiting component along the first direction. At this time, the lever component remains in the first posture, that is, the lower pressing surface is lower than the upper surface of the first plate body of the connector plate. When the first driving component drives the first pressing member to move along the second direction, the first pressing member presses the connector plate against the first limiting component along the second direction, thereby achieving positioning of the connector plate along the second direction. Simultaneously, during the second movement of the first pressing member, the lower pressing surface is squeezed by the first plate body, forcing the first elastic member to elastically deform, thereby causing the lever component to rotate to the second posture. The lower pressing surface of the lever component presses against the upper side of the first plate body, that is, the lever component presses the first plate body against the first limiting component. This invention's clamping device, through the cooperation of the first driving component, the first lever component, the first elastic member, and the first pressing member, achieves clamping and fixing of the connector plate in two directions using a single driving source, reducing the number of driving sources, lowering the manufacturing cost of the clamping device, and making the structure of the clamping device more compact.

[0031] The welding equipment of this utility model, by adopting the above-mentioned clamping device, can reliably fix the terminal block to be welded, and has a compact structure and low cost. Attached Figure Description

[0048] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not the entire structure.

[0049] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between 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.

[0050] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0051] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0052] The manufacturing process of smart meters involves soldering between the wiring terminals and the terminal block, such as... Figure 1 and Figure 2As shown, the end of the terminal block 50 overlaps with the end of the terminal block 60 and is soldered together. Specifically, the terminal block 50 includes a first plate body 51, a second plate body 52, a third plate body 53, and a fourth plate body 54. The second plate body 52 is connected to the first plate body 51 and is perpendicular to it. The third plate body 53 is connected to the second plate body 52 and is perpendicular to both the first plate body 51 and the second plate body 52. ​​A gap 56 is formed between the third plate body 53 and the first plate body 51. The fourth plate body 54 is connected to the end of the third plate body 53 away from the second plate body 52 and extends towards the side opposite to the first plate body 51. The fifth plate body 55 is connected to the fourth plate body 54 and is parallel to the first plate body 51. The terminal block 60 includes an overlap portion 61 and a cylindrical portion 62, the cylindrical portion 62 being used for threading wires. The side wall of the cylindrical part 62 is provided with a mounting hole 621 for fasteners to pass through in order to lock the wire inside the cylindrical part 62. The overlapping part 61 is connected to the cylindrical part 62 and overlaps the fifth plate part 55. The overlapping part 61 and the fifth plate part 55 are connected by welding.

[0053] To achieve relative fixation between the wiring terminal 60 and the terminal block 50 before soldering, such as Figure 3 As shown, this embodiment provides a clamping device for clamping a terminal block 50 and a terminal block 60 respectively, and for making the overlapping portion 61 of the terminal block 60 overlap the fifth plate body portion 55 of the terminal block 50. Specifically, the clamping device includes a support mechanism 30, a first clamping mechanism 10, and a second clamping mechanism 20. Both the first clamping mechanism 10 and the second clamping mechanism 20 are mounted on the support mechanism 30 to ensure the accuracy of the relative position of the first clamping mechanism 10 and the second clamping mechanism 20, thereby ensuring that the overlapping portion 61 of the terminal block 60 clamped by the second clamping mechanism 20 just overlaps the fifth plate body portion 55 of the terminal block 50 clamped by the first clamping mechanism 10.

[0054] In this embodiment, the direction perpendicular to the first plate portion 51 is defined as the first direction, the direction perpendicular to the third plate portion 53 is defined as the second direction, and the direction perpendicular to the second plate portion 52 is defined as the third direction. The first direction, the second direction, and the third direction are perpendicular to each other.

[0055] like Figures 4-7As shown, the first clamping mechanism 10 includes a first mounting plate 19, a first limiting component 11, a first driving component 12, a first pressing member 13, a lever component 14, and a first elastic member 15. The first mounting plate 19 is connected to the support mechanism 30, and the first limiting component 11, the first driving component 12, the first pressing member 13, the lever component 14, and the first elastic member 15 are all mounted on the first mounting plate 19. The first limiting component 11 is used to support the wiring plate 50 in a first direction and to stop the wiring plate 50 in a second direction. The first pressing member 13 is connected to the output end of the first driving component 12. The lever component 14 is pivotally connected to the first pressing member 13. The first elastic member 15 is connected between the first pressing member 13 and the lever component 14. The lever component 14 is in a first posture (e.g., Figure 6 When (as shown), the lower abutment surface 1421 of the lever assembly 14 near the first limiting assembly 11 is lower than the upper surface of the connector plate 50; the first drive assembly 12 can drive the first abutment member 13 to move in the second direction, so as to press the connector plate 50 against the first limiting assembly 11 in the second direction, and force the lever assembly 14 to rotate to the second posture, in the second posture (as shown) Figure 7 As shown, the lower pressing surface 1421 presses the wiring plate 50 against the first limiting component 11 along the first direction.

[0056] In this embodiment, when the wiring board 50 is placed on the first clamping mechanism 10, the first plate portion 51 of the wiring board 50 is supported on the first limiting component 11 along the first direction. At this time, the lever component 14 is in the first posture (e.g., Figure 6 As shown), that is, the lower pressing surface 1421 is lower than the upper surface of the first plate body portion 51 of the connector 50. When the first driving assembly 12 drives the first pressing member 13 to move in the second direction, the first pressing member 13 presses the connector 50 against the first limiting assembly 11 in the second direction, thereby achieving the positioning of the connector 50 in the second direction; at the same time, during the second movement of the first pressing member 13, the lower pressing surface 1421 is squeezed by the first plate body portion 51, forcing the first elastic member 15 to deform elastically, thereby causing the lever assembly 14 to rotate to the second posture (as shown). Figure 7As shown, the lower pressing surface 1421 of the lever assembly 14 presses against the upper side of the first plate body 51, that is, the lever assembly 14 presses the first plate body 51 against the first limiting assembly 11. In this embodiment, the clamping device, through the cooperation of the first driving assembly 12, the first lever assembly 14, the first elastic member 15, and the first pressing member 13, achieves clamping and fixing of the terminal block 50 in two directions using a single driving source, reducing the number of driving sources, lowering the manufacturing cost of the clamping device, and making the structure of the clamping device more compact. Furthermore, by mounting the first limiting assembly 11, the first driving assembly 12, the first pressing member 13, the lever assembly 14, and the first elastic member 15 all on the first mounting plate 19, the first clamping mechanism 10 can be assembled as a whole and then installed onto the support mechanism 30. This not only facilitates assembly but also helps ensure the relative positional accuracy between the various components of the first clamping mechanism 10, thereby ensuring the reliability of clamping the terminal block 50.

[0057] like Figure 4 and Figure 5 As shown, the first limiting component 11 includes a support member 111 and a first stop member 112. The support member 111 is mounted on the first mounting plate 19 and is used to support the wiring plate 50 along a first direction. Specifically, the support member 111 is used to support the first plate body portion 51. The first stop member 112 is disposed on the side of the support member 111 away from the lever assembly 14 along a second direction. The height of the first stop member 112 along the first direction is higher than that of the support member 111, so as to stop the wiring plate 50 along the second direction. Specifically, the first stop member 112 is used to stop the end face of the first plate body portion 51. In this embodiment, the cross-section of the first stop member 112 is smaller than the cross-section of the spacer portion 56, thereby ensuring that the first stop member 112 can be smoothly inserted into the spacer portion 56 of the wiring plate 50, avoiding positional interference between the first limiting component 11 and the wiring plate 50.

[0058] In this embodiment, as Figure 6 As shown, the first limiting component 11 also includes a support member 114, which is disposed on the side of the support member 111 near the lever assembly 14. The upper surface of the support member 111 is lower than the upper surface of the wiring plate 50 supported on the support member 111. The support member 111 is used to support the lower abutment surface 1421 of the lever assembly 14 near the first limiting component 11, thereby keeping the lever assembly 14 in the first posture. In other embodiments, the support member 114 may not be provided. Instead, when the first elastic member 15 is at its original length, the lower abutment surface 1421 of the lever assembly 14 near the first limiting component 11 is lower than the upper surface of the wiring plate 50 supported on the support member 111, which can also keep the lever assembly 14 in the first posture.

[0059] In this embodiment, as Figure 4 and Figure 5As shown, the first driving component 12 can be a cylinder, which is located on one side of the first limiting component 11. A first pressing member 13 is located between the first driving component 12 and the first limiting component 11. The first pressing member 13 includes a fixing part 131, a mounting part 132, and a pressing part 133. The fixing part 131 is connected to the output end of the first driving component 12, the mounting part 132 is connected to the fixing part 131, and the lever component 14 is pivotally connected to the mounting part 132 via a pivot shaft 16. In this embodiment, the mounting part 132 includes two protrusions spaced apart along a third direction. The two ends of the pivot shaft 16 are respectively connected to the two protrusions. The lever component 14 is rotatably engaged with the pivot shaft 16 and is located between the two protrusions. The pressing part 133 is located on the side of the mounting part 132 facing the first limiting component 11 and is located to the side of the lever component 14. The pressing part 133 is used to press against the end face of the first plate portion 51 facing the first driving component 12.

[0060] like Figures 5-7 As shown, the lever assembly 14 includes a lever body 141, a roller 142, and a roller shaft 143. The lever body 141 is pivotally connected to the first pressing member 13 via a pivot shaft 16. The roller 142 is rotatably mounted on one end of the lever body 141 near the first limiting assembly 11 via the roller shaft 143, and a portion of the circumferential surface of the roller 142 forms the lower pressing surface 1421. Therefore, during the process of the first driving assembly 12 driving the first pressing member 13 along the second movement, during the process of the lever assembly 14 switching from the first posture to the second posture, the roller 142 rolls with the first plate body portion 51, reducing the friction between the lever assembly 14 and the wiring plate 50, ensuring smooth clamping of the wiring plate 50, and reducing wear on the lever assembly 14 and the wiring plate 50. In this embodiment, the lever body 141 is disposed between the two protrusions of the mounting part 132. The end of the lever body 141 near the first limiting component 11 includes two ribs spaced apart along the third direction. The two ends of the roller 143 are respectively mounted on the two ribs. The roller 142 is connected to the roller 143 and disposed between the two ribs.

[0061] like Figure 6 and Figure 7As shown, the middle part of the lever assembly 14 is pivotally connected to the first pressing member 13 via a pivot shaft 16. The first elastic member 15 connects the first pressing member 13 and the end of the lever assembly 14 away from the first limiting member 11. Positioning the first elastic member 15 at the end away from the first limiting member 11 facilitates the arrangement of the roller 142, roller 143, and pressing part 133, avoiding positional interference between the first elastic member 15 and these components, and ensuring the reliability of the transmission of the lever assembly 14. In this embodiment, the first elastic member 15 can be a spring. When the first driving assembly 12 does not drive the first pressing member 13 to approach the first limiting member 11 in the second direction, the first elastic member 15 can be in its original length or slightly compressed state. When the first driving assembly 12 drives the first pressing member 13 to approach the first limiting member 11 in the second direction, the first elastic member 15 is further compressed, thereby causing the lower pressing surface 1421 of the lever assembly 14 to press against the upper surface of the first plate part 51. When the first drive assembly 12 drives the first pressing member 13 away from the first limiting assembly 11 in the second direction, the wiring plate 50 can be removed from the first clamping mechanism 10. At this time, the first elastic member 15 makes the lower pressing surface 1421 of the lever assembly 14 lower than the upper surface of the first plate body portion 51 of the wiring plate 50 again.

[0062] like Figure 4 and Figure 5 As shown, the first limiting component 11 can also stop the connector plate 50 in a third direction. The first clamping mechanism 10 also includes a second driving component 17 and a second pressing member 18. The second pressing member 18 is connected to the output end of the second driving component 17. The second driving component 17 is used to drive the second pressing member 18 in a third direction, so that the second pressing member 18 presses the connector plate 50 against the first limiting component 11 in a third direction, thereby realizing the clamping and positioning of the connector plate 50 in the third direction. In summary, the first clamping mechanism 10 of this embodiment, through the cooperation of the first driving component 12, the first pressing member 13, the lever component 14, the first limiting component 11, the second driving component 17, and the second pressing member 18, realizes the clamping and fixing of the connector plate 50 in three directions—the second direction, the third direction, and the first direction—through two driving sources. The structure is compact and the cost is low.

[0063] Specifically, such as Figure 4 and Figure 5As shown, the first limiting component 11 also includes a second stop 113, which is disposed on one side of the support 111 along a third direction. The second stop 113 is used to stop the wiring plate 50 along the third direction. In this embodiment, the second stop 113 and the support 111 are spaced apart in the third direction. The second plate portion 52 of the wiring plate 50 is disposed between the second stop 113 and the support 111. The second stop 113 is used to stop the second plate portion 52 along the third direction. The support 111 is provided with a through hole 1111 extending along the third direction. The second pressing member 18 passes through the through hole 1111 so as to press the second plate portion 52 of the wiring plate 50 against the second stop 113 along the third direction.

[0064] like Figure 8 and Figure 9 As shown, the second clamping mechanism 20 includes a second mounting plate 25, a second limiting component 21, a limiting post 22, a push plate 23, and a third driving component 24. Both the second limiting component 21 and the third driving component 24 are mounted on the second mounting plate 25. The second limiting component 21 has a limiting groove 210, which can limit the terminal 60 along a third direction. The limiting post 22 protrudes from the inner wall of the limiting groove 210 perpendicular to the first direction (i.e., the bottom wall of the limiting groove 210), and is used to pass through the mounting hole 621 on the terminal 60. The push plate 23 is slidably engaged with the second limiting component 21 along a second direction. The third driving component 24 is drively connected to the push plate 23 and is used to drive the push plate 23 to move along the second direction, so that the push plate 23 presses the terminal 60 against the limiting post 22 along the second direction. Based on the third-direction positioning of the terminal 60 by the limiting groove 210, the second-direction positioning of the terminal 60 by the push plate 23 and the positioning post, and the relative positional accuracy of the first clamping mechanism 10 and the second clamping mechanism 20, it can be ensured that the overlapping part 61 of the terminal 60 can accurately overlap on the fifth plate body 55 of the terminal board 50, ensuring reliable welding of the terminal board 50 and the terminal 60. Furthermore, by mounting the second limiting component 21 and the third driving component 24 on the second mounting plate 25, the second clamping mechanism 20 can be assembled as a whole and then installed onto the support mechanism 30. This not only facilitates assembly but also helps ensure the relative positional accuracy between the various components of the second clamping mechanism 20, thereby ensuring the reliability of clamping the terminal 60. In this embodiment, the cross-section of the limiting post 22 is smaller than the cross-section of the mounting hole 621 on the terminal 60, allowing it to be smoothly inserted into the mounting hole 621.

[0065] like Figure 8As shown, the second limiting component 21 includes a U-shaped part 211 and a sliding guide 212. The U-shaped part 211 is connected to the second mounting plate 25 and forms an upward-opening limiting groove 210. The sliding guide 212 is connected to the U-shaped part 211 and extends along a third direction. The sliding guide 212 protrudes from the U-shaped part 211 along the third direction to facilitate the push plate 23 to engage with the sliding guide 212 and slide, thereby pressing the terminal 60 against the limiting post 22 along the third direction. In this embodiment, two sliding guides 212 are provided and are located at both ends of the U-shaped part 211 along the third direction. The push plate 23 slides with both ends of the two sliding guides 212 along the third direction. It is understood that the U-shaped part 211 can be a one-piece molded component or it can be formed by assembling two or more components, which is not limited here.

[0066] like Figure 8 and Figure 9 As shown, the third drive assembly 24 includes a cam 241 and a second elastic member 242. The cam 241 is rotatable relative to the second limiting assembly 21. In this embodiment, the cam 241 is rotatably engaged with the second mounting plate 25 and is located on the side of the push plate 23 away from the U-shaped member 211. The second elastic member 242 connects the second limiting assembly 21 and the push plate 23 and is used to keep the push plate 23 abutting against the cam surface of the cam 241. When the cam 241 is driven to rotate, the outer peripheral surface of the cam 241 drives the push plate 23 to press against the terminal 60 in the second direction, thereby achieving clamping and fixing of the terminal 60 in the second direction. During this process, the second elastic member 242 is compressed and stores elastic potential energy. When the cam 241 is driven in the reverse direction, the second elastic element 242 releases its stored elastic potential energy and drives the push plate 23 away from the terminal 60 in the second direction, thereby facilitating the removal of the soldered terminal 60 from the second clamping mechanism 20. Simultaneously, the second elastic element 242 ensures that the push plate 23 remains in contact with the cam 241, so that the push plate 23 can be driven to move when the cam 241 rotates next time. In this embodiment, a second elastic element 242 is provided between each sliding guide 212 and the push plate 23. The cam 241 is rotatably mounted on the second mounting plate 25 via a mounting shaft 244. Optionally, the cam 241 is also connected to a handle 243, which is used for user operation to facilitate convenient rotation of the cam 241. Of course, in some embodiments (not shown), the cam 241 can also be driven to rotate by a drive source such as a motor; this is not specifically limited here.

[0067] like Figure 3As shown, this embodiment also provides a welding device, which includes a welding apparatus 40 and the aforementioned clamping device. The welding apparatus 40 is used to weld the terminal block 50 and the terminal block 60 on the clamping device. By employing the aforementioned clamping device, the welding device can reliably fix the terminal block 50 and the terminal block 60 to be welded, and has a small number of drive sources, a compact structure, and low cost.

[0068] In this embodiment, as Figure 3 As shown, the welding device 40 includes a first electrode 41 and a second electrode, wherein the first electrode 41 and the second electrode are respectively located on both sides of the overlapping portion between the terminal block 60 and the terminal block 50, thereby welding the overlapping portion. In this embodiment, the first electrode 41 is mounted on the support mechanism 30 and is located on the lower side of the overlapping portion between the terminal block 50 and the terminal block 60, while the second electrode is located on the upper side of the overlapping portion between the terminal block 50 and the terminal block 60. Specifically, the support mechanism 30 includes a first support plate 31, a second support plate 32, and a column 33, wherein the first clamping mechanism 10 and the second clamping mechanism 20 are both mounted on the first support plate 31. The second support plate 32 is disposed on the side of the first support plate 31 opposite to the first clamping mechanism 10 and the second clamping mechanism 20, and is connected to the first support plate 31 through the column 33. The first electrode 41 is mounted on the second support plate 32. The first support plate 31 is provided with a clearance hole 311. The upper end of the first electrode 41 passes through the clearance hole 311 and extends to the lower side of the overlapping part of the terminal block 50 and the terminal 60. Optionally, the first electrode 41 can be fixed to the second support plate 32 by existing fixing methods. The second electrode can be fixed by a bracket or manually held, as long as it can be located above the overlapping part of the terminal block 50 and the terminal 60.
