Description

Technical Field

[0001] The utility model relates to the technical field of electric energy meters, and more specifically, to a detection tooling and a detection component for an electric energy meter. Background Art

[0002] Electric energy meters are applicable to different scenarios such as measuring voltage, current, switching between the first loop and the second loop, etc. In cases where design variables such as voltage and current parameters are different, an error inspection bench is required.

[0003] In related technologies, the contact structures of different models of electric energy meters are inconsistent, and the contact structure between the error inspection bench and the electric energy meter may not be directly matched. External wiring is needed to connect the electric energy meter and the error detection bench for detection.

[0004] However, the detection method of connecting wires one by one is relatively complex, resulting in the production efficiency not being able to keep up with the production demand. Moreover, the wiring reliability is poor, and the disconnection caused by loosening will affect the detection result of the electric energy meter, leading to technical problems such as low production efficiency and large measurement errors of the electric energy meter. Summary of the Utility Model

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art.

[0006] To this end, a first aspect of the utility model provides a detection tooling for an electric energy meter.

[0007] A second aspect of the utility model provides a detection component.

[0008] In view of this, a first aspect of the utility model provides a detection tooling for an electric energy meter. The electric energy meter includes a plug. The detection tooling for the electric energy meter includes: a support member; a clamping member disposed on the support member, the clamping member being used to provide clamping and positioning for the plug, and the clamping member being capable of being electrically connected to the plug; and a wire harness, a first end of the wire harness being connected to the clamping member, and a second end of the wire harness being used to connect to a detection device.

[0009] In this technical solution, a detection tooling for an electric energy meter is defined. The electric energy meter can be installed on this detection tooling to connect to a detection device through the detection tooling, so as to detect the electrical parameters of the electric energy meter through the detection device, and calibrate the electric energy meter according to the detected results to ensure that the electrical detection accuracy of the produced electric energy meter meets the requirements.

[0010] The detection tooling for the electric energy meter includes a support member, a clamping member, and a wire harness.

[0011] The support member is used to provide positioning and support for other structures on the detection tooling. The support member can be fixed on a detection bench or a detection device, so as to fix the electric energy meter on the detection bench or the detection device together, so that the electric energy meter can be accurately and stably positioned during the detection process.

[0012] Specifically, the support component includes bakelite board. Bakelite material has high mechanical strength, good insulation, heat resistance and corrosion resistance. Selecting bakelite board as the support component can improve the support reliability and insulation reliability of the support component, and reduce the probability of problems such as misalignment of the electricity meter and electric leakage of the electricity meter.

[0013] The electricity meter is provided with plugs. During the use of the electricity meter, the electricity parameters of other electrical equipment can be detected through the plugs. The clamping components are installed on the support component. The number of clamping components is the same as the number of plugs on the electricity meter. Multiple clamping components correspond to multiple plugs on the electricity meter one by one. During the process of calibrating the electricity meter, the plugs on the electricity meter can be clamped on the clamping components, and the support component can position the electricity meter through the clamping components.

[0014] The clamping components are made of conductive material. The wire harness is also fixed on the support component. The first end of the wire harness is connected to the clamping component, and the second end of the wire harness is used to connect the detection equipment that can calibrate the electricity meter. After completing the clamping fit between the clamping component and the plug, and the connection between the wire harness and the detection equipment, the electricity meter and the detection equipment are electrically connected through the clamping component and the wire harness.

[0015] Among them, on different models of electricity meters, the number and position of the plugs are different. In this application, by arranging clamping components corresponding to the plug positions and the number of plugs on the support component, the electricity meter can directly complete the electrical connection with the detection equipment through the clamping action, enabling the detection equipment to immediately calibrate the electricity meter. Correspondingly, when it is necessary to calibrate other models of electricity meters, the detection tooling can be replaced, or the positions and the number of the clamping components on the support component can be adjusted, so that the replaced or adjusted detection tooling can be adapted to the new model of electricity meter, thereby realizing the rapid installation of the electricity meter and accelerating the calibration efficiency of the electricity meter.

[0016] It can be seen that the detection tooling of the electricity meter defined in this application replaces the wiring connection operation in the related technology through the clamping operation, thereby improving the calibration efficiency of the electricity meter through the clamping operation, enhancing the positioning reliability and calibration accuracy of the electricity meter through the reliable cooperation between the clamping component and the plug, and thus solving the technical problems of low production efficiency and large measurement error existing in the related technology.

[0017] In addition, the above-mentioned detection tooling of the electricity meter provided by the present utility model may also have the following additional technical features:

[0018] In some technical solutions of the present utility model, optionally, the clamping component includes: a metal sheet metal. The metal sheet metal is provided on the support component. The metal sheet metal includes a first bending portion and a second bending portion. The first bending portion and the second bending portion are symmetrically arranged, and the first bending portion and the second bending portion are used to clamp the plug.

[0019] In this technical solution, the clamping component includes a metal sheet metal, which is formed by stamping and bending processes. Among them, the metal sheet metal includes a bottom plate, a first bending portion, and a second bending portion. The first bending portion and the second bending portion are bent above the bottom plate through the bending process. The first bending portion and the second bending portion are symmetrically arranged on the bottom plate, and the distance between the first bending portion and the second bending portion is less than the width of the cross-section of the plug on the electricity meter.

[0020] During the calibration of the electricity meter, the plug is inserted between the first bending portion and the second bending portion. The first bending portion and the second bending portion that are forced to deform clamp the inserted plug through elastic force, thereby realizing the mating connection between the plug and the clamping component. The electricity meter can be fixed on the support component by means of the clamping component, ensuring the positioning stability of the electricity meter during the detection process on the one hand, and the electrical connection stability between the electricity meter and the detection equipment on the other hand.

[0021] Selecting an integrally formed metal sheet metal as the clamping component can reduce the process complexity of the clamping component, and the integrally formed metal sheet metal does not include a structural section and has strong structural toughness, and the probability of irreversible deformation or fracture problems during frequent plugging and unplugging operations is relatively low, thereby achieving the technical effects of reducing the production cost of the clamping component and extending the service life of the clamping component.

[0022] In some technical solutions of the present utility model, optionally, one side of the first bending portion facing away from the support component includes a first inclined surface, and one side of the second bending portion facing away from the support component includes a second inclined surface; the first inclined surface and the second inclined surface enclose a first V-shaped groove.

[0023] In this technical solution, the first inclined surface is formed by the first bending portion through the bending process, and the second inclined surface is formed by the second bending portion through the bending process. The first inclined surface is inclined with respect to the height direction and the width direction of the detection tooling, and the second inclined surface is inclined with respect to the height direction and the width direction of the detection tooling, and the first inclined surface and the second inclined surface are symmetric.

[0024] Among them, the first inclined surface and the second inclined surface face away from the support component, and the symmetric first inclined surface and second inclined surface enclose a first V-shaped groove facing above the detection tooling. During the process of the plug on the electricity meter being inserted downward into the clamping component, the plug first contacts the first inclined surface and the second inclined surface, and the first bending portion and the second bending portion are pushed to open until the first bending portion and the second bending portion clamp the plug.

[0025] It can be seen that the first inclined surface and the second inclined surface can play a guiding role during the insertion of the electricity meter, ensuring that the plug can be smoothly inserted between the first bending portion and the second bending portion, thereby achieving the technical effects of reducing the plug clamping difficulty and improving the assembly efficiency of the electricity meter.

[0026] In some technical solutions of the present utility model, optionally, one side of the first bending portion facing the support member includes a third inclined surface, and one side of the second bending portion facing the support member includes a fourth inclined surface; the third inclined surface and the fourth inclined surface enclose a second V-shaped groove.

[0027] In this technical solution, the first bending portion forms the third inclined surface through a bending process, the second bending portion forms the fourth inclined surface through a bending process, the third inclined surface is inclined with respect to the height direction and the width direction of the detection tooling, the fourth inclined surface is inclined with respect to the height direction and the width direction of the detection tooling, and the third inclined surface and the fourth inclined surface are symmetrical.

[0028] Wherein, the third inclined surface and the fourth inclined surface face the support member, and the symmetrical third inclined surface and the fourth inclined surface enclose a second V-shaped groove facing above the detection tooling. During the process of removing the plug inserted into the clamping member from the clamping member, the front end of the plug first contacts the third inclined surface and the fourth inclined surface, and the first bending portion and the second bending portion are pushed open by pushing the third inclined surface and the fourth inclined surface until the plug exits the space between the first bending portion and the second bending portion.

[0029] It can be seen that the third inclined surface and the fourth inclined surface can play a guiding role during the disassembly process of the electric energy meter, ensuring that the plug can be smoothly removed from between the first bending portion and the second bending portion, thereby achieving the technical effects of reducing the difficulty of plug disassembly and improving the disassembly efficiency of the electric energy meter.

[0030] In some technical solutions of the present utility model, optionally, the first bending portion and the second bending portion are arranged at intervals.

[0031] In this technical solution, a gap is left between the first bending portion and the second bending portion. By leaving a gap between the first bending portion and the second bending portion, the insertion difficulty of the plug can be reduced, and it is convenient to embed the front end of the plug between the first bending portion and the second bending portion.

[0032] On this basis, the width of the gap is smaller than the width of the plug on the electric energy meter, so that the plug can force the first bending portion and the second bending portion to open outwards, enabling the first bending portion and the second bending portion that generate elastic deformation to clamp the plug through elastic force, thereby improving the clamping stability of the plug and reducing the probability of the plug loosening or even falling off, and achieving the technical effects of improving the positioning accuracy of the electric energy meter and the calibration accuracy of the electric energy meter.

[0033] In some technical solutions of the present utility model, optionally, one first bending portion and one second bending portion form a clamping group; the metal sheet includes a plurality of clamping groups, and the plurality of clamping groups are distributed at intervals along the first direction.

[0034] In this technical solution, a plurality of clamping groups are provided on the bottom plate of the metal sheet metal. Each clamping group includes a first bending part and a second bending part, and the plurality of clamping groups are spaced apart on the bottom plate.

[0035] By providing a plurality of clamping groups, the same plug can be clamped by the plurality of clamping groups together, thereby improving the stability and reliability of the plug clamping and positioning, reducing the probability of the plug loosening or even falling off, and further achieving the technical effects of improving the positioning accuracy of the electric energy meter and the calibration accuracy of the electric energy meter.

[0036] In some technical solutions of the present utility model, optionally, a first anti-corrosion layer is included on the outer surface of the metal sheet metal; the first anti-corrosion layer includes: a nickel layer, a zinc layer or a chromium layer.

[0038] Among them, the first anti-corrosion layer includes a nickel layer, a zinc layer or a chromium layer. By providing the first anti-corrosion layer on the outer surface of the metal sheet metal, it is possible to prevent the metal sheet metal from being eroded by external pollutants, and further achieve the technical effects of improving the electrical connection stability between the electric energy meter and the detection device and extending the service life of the clamping components.

[0039] Specifically, the metal sheet metal can pass a current of 120 A within a short time.

[0040] In some technical solutions of the present utility model, optionally, the clamping component further includes: a metal plate, the metal plate is connected to the support component, and the wire harness and the metal sheet metal are connected to the metal plate.

[0041] In this technical solution, the clamping component further includes a metal plate. The metal plate is disposed between the support component and the metal sheet metal, and the metal sheet metal is fixed to the support component through the metal plate. Among them, the wire harness is connected to the metal plate, and the electric energy meter is electrically connected to the detection device through the plug, the metal sheet metal, the metal plate and the wire harness.

[0042] By providing a metal plate between the metal sheet metal and the support component, on the one hand, the contact area between the clamping component and the support component can be increased, thereby improving the positioning stability of the clamping component on the support component, reducing the probability of the clamping component being skewed or misaligned, and further achieving the technical effects of improving the positioning accuracy and calibration accuracy of the electric energy meter. On the other hand, the metal plate can provide an area for connecting the wire harness outside the metal sheet metal, facilitating the fixing of the first end of the wire harness on the clamping component, and further achieving the technical effects of reducing the assembly difficulty and assembly complexity.

[0043] In some technical solutions of the present utility model, optionally, the support component includes a slot, and the metal plate includes a protruding portion, and the protruding portion is clamped in the slot.

[0044] In this technical solution, a slot is formed on one side of the supporting component facing the clamping component. Correspondingly, a protruding portion is provided at the bottom of the metal plate. During the assembly process, the protruding portion is inserted into the slot to complete the preliminary positioning of the clamping component, thereby reducing the probability of misalignment of the clamping component on the supporting component and ensuring that the number and spatial layout of the clamping components can match the corresponding model of the electricity meter. Furthermore, the technical effects of improving the assembly accuracy of the clamping component and increasing the yield rate of the detection tooling of the electricity meter are achieved.

[0045] In some technical solutions of the present utility model, optionally, the metal sheet metal includes a first mounting hole, the metal plate includes a second mounting hole, and the clamping component further includes: a connecting member, and the connecting member passes through the first mounting hole and the second mounting hole.

Finally, the metal sheet metal is fixed by a connecting member passing through the first mounting hole and the second mounting hole. Specifically, the connecting member includes a screw, a bolt or a pin.

[0047] By providing the above connection structure, the assembly difficulty of the clamping component can be reduced. Moreover, the metal sheet metal is detachable relative to the metal plate. When a failure occurs in the clamping component, the user can remove the metal sheet metal to complete the maintenance or replacement of the metal sheet metal, thereby achieving the technical effect of reducing the maintenance difficulty of the detection tooling of the electricity meter.

Detailed Embodiments

[0069] In order to be able to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described in detail below in conjunction with the drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0070] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present utility model is not limited by the specific embodiments disclosed below.

[0071] The following is a reference to Figures 1 to 3 Describe a detection tooling and a detection component of an electric energy meter according to some embodiments of the present invention.

[0072] As Figure 1 As shown, an embodiment of the present invention provides a detection tooling 100 for an electric energy meter. The electric energy meter includes a plug. The detection tooling 100 for the electric energy meter includes: a support member 110; a clamping member 120, the clamping member 120 is arranged on the support member 110, the clamping member 120 is used to provide clamping and positioning for the plug, and the clamping member 120 can be electrically connected to the plug; a wire harness 130, the first end of the wire harness 130 is connected to the clamping member 120, and the second end of the wire harness 130 is used to connect to a detection device.

[0073] In this embodiment, a detection tooling 100 for an electric energy meter is defined. The electric energy meter can be installed on this detection tooling to connect to a detection device through the detection tooling, so as to detect the electrical parameters of the electric energy meter through the detection device, and calibrate the electric energy meter according to the detected results to ensure that the power detection accuracy of the produced electric energy meter meets the requirements.

[0074] The detection tooling 100 for the electric energy meter includes a support member 110, a clamping member 120 and a wire harness 130.

[0075] The support member 110 is used to provide positioning and support for other structures on the detection tooling. The support member 110 can be fixed on a detection table or a detection device, so as to fix the electric energy meter on the detection table or the detection device together, so that the electric energy meter can be accurately and stably positioned during the detection process.

[0076] Specifically, the support member 110 includes an insulating board. The insulating board material has high mechanical strength, good insulation, heat resistance and corrosion resistance. Selecting the insulating board as the support member 110 can improve the support reliability and insulation reliability of the support member 110, and reduce the probability of problems such as misalignment of the electric energy meter and leakage of the electric energy meter.

[0077] A plug is arranged on the electric energy meter, and the electric energy parameters of other electrical equipment can be detected through the plug during the use of the electric energy meter. The clamping member 120 is installed on the support member 110. The number of the clamping members 120 is the same as the number of the plugs on the electric energy meter. The multiple clamping members 120 correspond to the multiple plugs on the electric energy meter one by one. During the calibration of the electric energy meter, the plugs on the electric energy meter can be clamped on the clamping members 120, and the support member 110 can position the electric energy meter through the clamping members 120.

[0078] The clamping component 120 is made of conductive material. The wire harness 130 is also fixed on the support component 110. The first end of the wire harness 130 is connected to the clamping component 120, and the second end of the wire harness 130 is used to connect a detection device capable of calibrating the electricity meter. After completing the clamping fit between the clamping component 120 and the plug, and the connection between the wire harness 130 and the detection device, an electrical connection is achieved between the electricity meter and the detection device through the clamping component 120 and the wire harness 130.

[0079] Among them, on electricity meters of different models, the number and positions of the plugs are different. In this application, by arranging the clamping components 120 corresponding to the positions and numbers of the plugs on the support component 110, the electricity meter can directly complete the electrical connection with the detection device through the clamping action, enabling the detection device to immediately calibrate the electricity meter. Correspondingly, when it is necessary to calibrate other models of electricity meters, the detection tooling can be replaced, or the positions and numbers of the clamping components 120 on the support component 110 can be adjusted, so that the replaced or adjusted detection tooling can be adapted to the new model of the electricity meter, thereby realizing the rapid installation of the electricity meter and accelerating the calibration efficiency of the electricity meter.

[0080] It can be seen that the detection tooling 100 for the electricity meter defined in this application replaces the wiring connection operation in the related art through the clamping operation, thereby improving the calibration efficiency of the electricity meter through the clamping operation, enhancing the positioning reliability and calibration accuracy of the electricity meter through the reliable cooperation between the clamping component 120 and the plug, and further solving the technical problems of low production efficiency and large measurement errors existing in the related art.

[0081] Specifically, the support component 110 and the wire harness 130 are connected through a second connection component 162, and the second connection component 162 includes a connecting post and a pressing screw.

[0082] As Figure 2 and Figure 3 shown, in some embodiments of the present utility model, optionally, the clamping component 120 includes: a metal sheet 122, the metal sheet 122 is arranged on the support component 110, the metal sheet 122 includes a first bending portion 1222 and a second bending portion 1224, the first bending portion 1222 and the second bending portion 1224 are symmetrically arranged, and the first bending portion 1222 and the second bending portion 1224 are used for clamping the plug.

[0083] In this embodiment, the clamping component 120 includes a metal sheet metal 122, which is formed by stamping and bending processes. Among them, the metal sheet metal 122 includes a bottom plate, a first bending portion 1222, and a second bending portion 1224. The first bending portion 1222 and the second bending portion 1224 are bent above the bottom plate through the bending process. The first bending portion 1222 and the second bending portion 1224 are symmetrically arranged on the bottom plate, and the distance between the first bending portion 1222 and the second bending portion 1224 is less than the width of the cross-section of the plug on the electricity meter.

[0084] During the process of calibrating the electricity meter, the plug is inserted between the first bending portion 1222 and the second bending portion 1224. The first bending portion 1222 and the second bending portion 1224 that are forced to deform clamp the inserted plug through elastic force, thereby realizing the mating connection between the plug and the clamping component 120. The electricity meter can be fixed on the support component 110 by means of the clamping component 120. On the one hand, it ensures the positioning stability of the electricity meter during the detection process, and on the other hand, it ensures the electrical connection stability between the electricity meter and the detection equipment.

[0085] Selecting the integrally formed metal sheet metal 122 as the clamping component 120 can reduce the process complexity of the clamping component 120. And the integrally formed metal sheet metal 122 does not include a structural cross-section and has strong structural toughness, so the probability of irreversible deformation or fracture problems during frequent plugging and unplugging operations is relatively low. Furthermore, it realizes the technical effects of reducing the production cost of the clamping component 120 and extending the service life of the clamping component 120.

[0086] As Figure 2 and Figure 3 shown, in some embodiments of the present utility model, optionally, the side of the first bending portion 1222 facing away from the support component 110 includes a first inclined surface 12222, and the side of the second bending portion 1224 facing away from the support component 110 includes a second inclined surface 12242; the first inclined surface 12222 and the second inclined surface 12242 enclose a first V-shaped groove.

[0087] In this embodiment, the first bending portion 1222 forms the first inclined surface 12222 through the bending process, and the second bending portion 1224 forms the second inclined surface 12242 through the bending process. The first inclined surface 12222 is inclined with respect to the height direction (the arrow a shown in Figure 1 、 Figure 2 and Figure 3 ) and the width direction (the arrow b shown in Figure 1 、 Figure 2 and Figure 3 ) of the detection tooling, and the second inclined surface 12242 is inclined with respect to the height direction and the width direction of the detection tooling, and the first inclined surface 12222 and the second inclined surface 12242 are symmetric.

[0088] Among them, the first inclined surface 12222 and the second inclined surface 12242 face away from the support member 110. The symmetric first inclined surface 12222 and the second inclined surface 12242 enclose a first V-shaped groove facing upward above the detection tooling. During the process of the plug on the electricity meter being inserted downward into the clamping member 120, the plug first contacts the first inclined surface 12222 and the second inclined surface 12242, and by pushing the first inclined surface 12222 and the second inclined surface 12242, the first bending portion 1222 and the second bending portion 1224 are opened until the first bending portion 1222 and the second bending portion 1224 clamp the plug.

[0089] It can be seen that the first inclined surface 12222 and the second inclined surface 12242 can play a guiding role during the insertion process of the electricity meter, ensuring that the plug can be smoothly inserted between the first bending portion 1222 and the second bending portion 1224, thereby achieving the technical effects of reducing the clamping difficulty of the plug and improving the assembly efficiency of the electricity meter.

[0090] Such as Figure 2 and Figure 3 shown, in some embodiments of the present utility model, optionally, one side of the first bending portion 1222 facing the support member 110 includes a third inclined surface 12224, and one side of the second bending portion 1224 facing the support member 110 includes a fourth inclined surface 12244; the third inclined surface 12224 and the fourth inclined surface 12244 enclose a second V-shaped groove.

[0091] In this embodiment, the first bending portion 1222 forms the third inclined surface 12224 through a bending process, and the second bending portion 1224 forms the fourth inclined surface 12244 through a bending process. The third inclined surface 12224 is inclined with respect to the height direction and the width direction of the detection tooling, and the fourth inclined surface 12244 is inclined with respect to the height direction and the width direction of the detection tooling, and the third inclined surface 12224 and the fourth inclined surface 12244 are symmetric.

[0092] Among them, the third inclined surface 12224 and the fourth inclined surface 12244 face the support member 110. The symmetric third inclined surface 12224 and the fourth inclined surface 12244 enclose a second V-shaped groove facing upward above the detection tooling. During the process of the plug inserted into the clamping member 120 being taken out from the clamping member 120, the front end of the plug first contacts the third inclined surface 12224 and the fourth inclined surface 12244, and by pushing the third inclined surface 12224 and the fourth inclined surface 12244, the first bending portion 1222 and the second bending portion 1224 are opened until the plug exits the space between the first bending portion 1222 and the second bending portion 1224.

[0093] Thus, it can be seen that the third inclined surface 12224 and the fourth inclined surface 12244 can play a guiding role during the disassembly of the electricity meter, ensuring that the plug can be smoothly removed between the first bending portion 1222 and the second bending portion 1224, thereby achieving the technical effects of reducing the difficulty of plug disassembly and improving the disassembly efficiency of the electricity meter.

[0094] As Figure 2 and Figure 3 shown, in some embodiments of the present invention, optionally, the first bending portion 1222 and the second bending portion 1224 are spaced apart.

[0095] In this embodiment, there is a gap between the first bending portion 1222 and the second bending portion 1224. By leaving a gap between the first bending portion 1222 and the second bending portion 1224, the insertion difficulty of the plug can be reduced, facilitating the insertion of the front end of the plug between the first bending portion 1222 and the second bending portion 1224.

[0096] On this basis, the width of the gap is smaller than the width of the plug on the electricity meter, so that the plug can force the first bending portion 1222 and the second bending portion 1224 to open outward, enabling the elastically deformed first bending portion 1222 and second bending portion 1224 to clamp the plug through elastic force, thereby improving the clamping stability of the plug and reducing the probability of the plug loosening or even falling off, achieving the technical effects of improving the positioning accuracy of the electricity meter and enhancing the calibration accuracy of the electricity meter.

[0097] As Figure 2 and Figure 3 shown, in some embodiments of the present invention, optionally, one first bending portion 1222 and one second bending portion 1224 form a clamping group 124; the metal sheet 122 includes a plurality of clamping groups 124, and the plurality of clamping groups 124 are spaced apart along the first direction ( Figure 2 indicated by the arrow c in

[0098] In this embodiment, a plurality of clamping groups 124 are provided on the bottom plate of the metal sheet 122. Each clamping group 124 includes a first bending portion 1222 and a second bending portion 1224, and the plurality of clamping groups 124 are spaced apart on the bottom plate.

[0099] By providing a plurality of clamping groups 124, the same plug can be clamped by the plurality of clamping groups 124 together, thereby improving the stability and reliability of plug clamping and positioning, reducing the probability of the plug loosening or even falling off, and further achieving the technical effects of improving the positioning accuracy of the electricity meter and enhancing the calibration accuracy of the electricity meter.

[0100] In some embodiments of the present invention, optionally, the outer surface of the metal sheet 122 includes a first anti-corrosion layer; the first anti-corrosion layer includes: a nickel layer, a zinc layer, or a chromium layer.

[0101] In this embodiment, a first anti-corrosion layer is provided on the outer surface of the metal sheet metal 122, and the first anti-corrosion layer can be formed on the outside of the metal sheet metal 122 through an electroplating process.

[0102] Among them, the first anti-corrosion layer includes a nickel layer, a zinc layer or a chromium layer. By providing the first anti-corrosion layer on the outer surface of the metal sheet metal 122, it is possible to prevent the metal sheet metal 122 from being eroded by external pollutants, thereby achieving the technical effects of improving the electrical connection stability between the electric energy meter and the detection device and extending the service life of the clamping component 120.

[0103] Specifically, the metal sheet metal 122 can pass a current of 120 A within a short period of time.

[0104] As Figure 1 shown, in some embodiments of the present invention, optionally, the clamping component 120 further includes: a metal plate 126, the metal plate 126 is connected to the support component 110, and the wire harness 130 and the metal sheet metal 122 are connected to the metal plate 126.

[0105] In this embodiment, the clamping component 120 further includes a metal plate 126. The metal plate 126 is disposed between the support component 110 and the metal sheet metal 122, and the metal sheet metal 122 is fixed to the support component 110 through the metal plate 126. Among them, the wire harness 130 is connected to the metal plate 126, and the electric energy meter is electrically connected to the detection device through the plug, the metal sheet metal 122, the metal plate 126 and the wire harness 130.

[0106] By providing the metal plate 126 between the metal sheet metal 122 and the support component 110, on the one hand, the contact area between the clamping component 120 and the support component 110 can be increased, thereby improving the positioning stability of the clamping component 120 on the support component 110, reducing the probability of the clamping component 120 being skewed or misaligned, and thus achieving the technical effects of improving the positioning accuracy and calibration accuracy of the electric energy meter. On the other hand, the metal plate 126 can provide an area for connecting the wire harness 130 outside the metal sheet metal 122, facilitating the fixing of the first end of the wire harness 130 on the clamping component 120, and thus achieving the technical effects of reducing the assembly difficulty and assembly complexity.

[0107] Specifically, the first ends of the metal plate 126, the support component 110 and the wire harness 130 are connected through a first connection component 160, and the first connection component 160 includes a connecting column and a pressing screw.

[0108] As Figure 1 shown, in some embodiments of the present invention, optionally, the support component 110 includes a slot 1102, and the metal plate 126 includes a protruding portion, and the protruding portion is clamped in the slot 1102.

[0109] In this embodiment, on one side of the support member 110 facing the clamping member 120, a slot 1102 is formed. Correspondingly, a protruding portion is provided at the bottom of the metal plate 126. During the assembly process, inserting the protruding portion into the slot 1102 can complete the initial positioning of the clamping member 120, thereby reducing the probability of misalignment of the clamping member 120 on the support member 110, ensuring that the number and spatial layout of the clamping members 120 can match the corresponding model of the electricity meter. Furthermore, the technical effects of improving the assembly accuracy of the clamping member 120 and increasing the yield rate of the detection tool 100 for the electricity meter are achieved.

[0110] As Figure 1 and Figure 2 shown, in some embodiments of the present invention, optionally, the metal sheet metal 122 includes a first mounting hole 1226, the metal plate 126 includes a second mounting hole, and the clamping member 120 further includes: a connecting member 140, and the connecting member 140 passes through the first mounting hole 1226 and the second mounting hole.

[0111] In this embodiment, a first mounting hole 1226 is formed on the bottom plate of the metal sheet metal 122, and a second mounting hole is formed on the metal plate 126. During the assembly process of the clamping member 120, first fix the metal plate 126 on the support member 110, then align the first mounting hole 1226 and the second mounting hole, and finally fix the metal sheet metal 122 through the connecting member 140 penetrating the first mounting hole 1226 and the second mounting hole. Specifically, the connecting member 140 includes a screw, a bolt or a pin.

[0112] By providing the above connection structure, the assembly difficulty of the clamping member 120 can be reduced. Moreover, the metal sheet metal 122 is detachable relative to the metal plate 126. When the clamping member 120 fails, the user can disassemble the metal sheet metal 122 to complete the maintenance or replacement of the metal sheet metal 122, thereby achieving the technical effect of reducing the maintenance difficulty of the detection tool 100 for the electricity meter.

[0113] In some embodiments of the present invention, optionally, the outer surface of the metal plate 126 includes a second anti-corrosion layer; the second anti-corrosion layer includes: a nickel layer, a zinc layer or a chromium layer.

[0114] In this embodiment, the outer surface of the metal plate 126 is provided with a second anti-corrosion layer, and the second anti-corrosion layer can be formed on the outside of the metal plate 126 by an electroplating process.

[0115] Among them, the second anti-corrosion layer includes a nickel layer, a zinc layer or a chromium layer. By providing the second anti-corrosion layer on the outer surface of the metal plate 126, the metal plate 126 can be prevented from being eroded by external pollutants, and further the technical effects of improving the electrical connection stability between the electricity meter and the detection device and extending the service life of the clamping member 120 are achieved.

[0116] Specifically, the metal plate 126 can pass a current of 120 A within a short period of time.

[0117] As Figure 1 shown, in some embodiments of the present utility model, optionally, the detection tooling 100 of the electric energy meter further includes: a shielding member 150, the shielding member 150 is connected to the support member 110, and at least a part of the wire harness 130 is located between the shielding member 150 and the support member 110.

[0118] In this embodiment, a shielding member 150 is further provided on the support member 110. After assembly, the shielding member 150 covers above the wire harness 130, thereby shielding at least a part of the wire harness 130 through the shielding member 150.

[0119] By providing the shielding member 150, the electric energy meter and the wire harness 130 can be separated. On the one hand, it protects the wire harness 130 from being scratched. On the other hand, it reduces the probability of a short - circuit problem between the electric energy meter and the wire harness 130, and further achieves the technical effect of improving the safety and reliability of the detection tooling 100 of the electric energy meter.

[0120] Specifically, the partition is made of bakelite material.

[0121] Specifically, the shielding member 150 is connected to the support member 110 through a bolt group 164.

[0122] As Figure 1 shown, in some embodiments of the present utility model, optionally, the number of clamping members 120 is multiple, and the multiple clamping members 120 are distributed at intervals on the support member 110.

[0123] In this embodiment, a plug is provided on the electric energy meter. During the use of the electric energy meter, the electric energy parameters of other electrical equipment can be detected through the plug. The clamping members 120 are installed on the support member 110. The number of clamping members 120 is the same as the number of plugs on the electric energy meter. The multiple clamping members 120 and the multiple plugs on the electric energy meter correspond one by one. During the calibration of the electric energy meter, the plugs on the electric energy meter can be clamped on the clamping members 120, and the support member 110 can position the electric energy meter through the clamping members 120.

[0124] Among them, on watt-hour meters of different models, the number and positions of the plugs are different. In this application, by arranging clamping components 120 corresponding to the positions and numbers of the plugs on the support component 110, the watt-hour meter can directly complete the electrical connection with the detection device through the clamping action, enabling the detection device to immediately calibrate the watt-hour meter. Correspondingly, when it is necessary to calibrate watt-hour meters of other models, the detection tooling can be replaced, or the positions and numbers of the clamping components 120 on the support component 110 can be adjusted, so that the replaced or adjusted detection tooling can be adapted to the new model of the watt-hour meter, thereby realizing the rapid installation of the watt-hour meter and accelerating the calibration efficiency of the watt-hour meter.

To avoid repetition, it will not be elaborated here.
