Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of electric energy meter calibration, especially to a three-phase electric energy meter multi-meter position auxiliary probe assembly and calibration device. BACKGROUND

[0002] In modern industry, calibration devices play a crucial role. Especially for the detection and calibration of electric power metering equipment such as electric energy meters, specially designed calibration assemblies are needed to ensure their accuracy and reliability. With the progress of science and technology and the increasingly stringent technical standards, efficient and accurate calibration of electric energy meters and other equipment has become a basic requirement in the industry.

[0003] Traditional calibration devices usually integrate multiple types of calibration assemblies for performing different testing tasks. In order to save space and optimize the layout, these assemblies are often designed in a stacked form along the vertical direction. However, such a layout, while effectively reducing the floor space, also brings new problems - namely, when some assemblies must be able to move horizontally to complete certain operations, they are prone to interference in position with other fixed or moving assemblies. For example, in the calibration process of electric energy meters, probes, as one of the key calibration assemblies, need to frequently approach or move away from the electric energy meters being tested to achieve contact measurement. When the probes move horizontally, they are prone to collision or obstruction with other assemblies also located in the vertical arrangement, which not only affects the calibration efficiency, but also can cause equipment damage and even safety risks. SUMMARY

[0004] The main purpose of the utility model is to provide a three-phase electric energy meter multi-meter position auxiliary probe assembly and calibration device, which can improve the space utilization and prevent interference between the assemblies in the calibration device.

[0008] a driven portion provided on the side of the electrical connection portion away from the probe along the first direction;

[0009] wherein the electrical connection portion has a first side and a second side oppositely arranged along a third direction, the third direction being perpendicular to the first direction and the second direction, the first side being adapted to provide a single-phase electric energy meter multi-meter position auxiliary probe assembly, the driven portion including a force receiving structure protruding along the third direction, the force receiving structure protruding towards the second side.

[0010] In some embodiments, the electric connection part comprises an upper shell, an electric connection plate and a lower shell, the lower shell is concave with a receiving groove for accommodating the electric connection plate, the upper shell is connected to the lower shell, and the electric connection plate is located between the upper shell and the lower shell along the third direction.

[0011] In some embodiments, the driven part is connected to the lower shell, and the end of the force receiving structure protruding towards the second side is higher than the upper shell along the third direction.

[0012] In some embodiments, the driven part comprises a connecting piece connected to the force receiving structure and the lower shell respectively, and the width of the connecting piece near the lower shell along the second direction is greater than the width of the connecting piece near the force receiving structure along the second direction along the first direction.

[0013] In some embodiments, the lower shell comprises a sliding block protruding along the second direction, and the sliding block is suitable for slidingly connecting the single-phase electric energy meter multi-meter position auxiliary probe assembly.

[0014] In some embodiments, the lower shell protrudes towards the upper shell along the third direction, the upper shell is provided with a first positioning groove extending along the first direction, the electric connection plate is provided with a second positioning groove extending along the first direction, the positioning structure is inserted into the first positioning groove and the second positioning groove along the first direction.

[0015] In some embodiments, the height of the positioning structure along the third direction gradually increases from the side close to the probe to the side away from the probe along the first direction.

[0016] In some embodiments, the three-phase electric energy meter multi-meter position auxiliary probe assembly comprises a three-phase strong electric auxiliary probe group socket and a three-phase weak electric auxiliary probe group socket, and the three-phase strong electric auxiliary probe group socket and the three-phase weak electric auxiliary probe group socket are connected to the side of the electric connection part away from the probe along the first direction.

[0017] In some embodiments, the three-phase strong electric auxiliary probe group socket and the three-phase weak electric auxiliary probe group socket are arranged at intervals along the second direction.

[0018] The second aspect of the embodiment of the utility model provides a kind of detection device, the detection device includes the three-phase electric energy meter multi-meter position auxiliary probe assembly of any one of the above, and the detection device further includes single-phase electric energy meter multi-meter position auxiliary probe assembly, and along three directions, the three-phase electric energy meter multi-meter position auxiliary probe assembly is stacked in single-phase electric energy meter multi-meter position auxiliary probe assembly;

[0019] Wherein, the single-phase electric energy meter multi-meter position auxiliary probe assembly comprises a sliding rail extending along the first direction, and the three-phase electric energy meter multi-meter position auxiliary probe assembly is slidingly connected to the single-phase electric energy meter multi-meter position auxiliary probe assembly.

[0020] According to the above embodiment, the utility model has the beneficial effects that:

[0021] The three-phase electric energy meter multi-meter position auxiliary probe assembly includes a probe, an electrical connection portion, and a driven portion. The probe has an axis that is disposed parallel to a first direction, and the probe is movable along the first direction to calibrate a device under test. The electrical connection portion extends along a second direction that is perpendicular to the first direction, and the probe is electrically connected to the electrical connection portion along a side of the electrical connection portion that is along the first direction. The driven portion is disposed on a side of the electrical connection portion that is away from the probe along the first direction. The electrical connection portion has a first side and a second side that are oppositely disposed along a third direction that is perpendicular to the first direction and the second direction, and the first side is adapted to be provided with a single-phase electric energy meter multi-meter position auxiliary probe assembly. The driven portion includes a force receiving structure that protrudes along the third direction, and the force receiving structure protrudes toward the second side.

[0022] It can be understood that, in order to make the driving force more stably act on the driving portion, i.e., to ensure that the probe moves smoothly along the first direction, a larger area of the driven portion needs to be provided to improve the force receiving effect. However, the electrical connection portion extends along the second direction, and the driving portion is connected to the electrical connection portion. The electrical connection portion is mainly used for electrically connecting the probe, and thus the thickness of the electrical connection portion is relatively thin. Therefore, the surface of the driving portion for bearing the driving force usually protrudes from the electrical connection portion along the thickness direction of the electrical connection portion, i.e., the force receiving structure protrudes along the third direction. When the three-phase electric energy meter multi-meter position auxiliary probe assembly moves along the first direction, the protruding force receiving structure is prone to interfering with other components in the device under test, which increases the accident rate.

[0023] The utility model discloses a protruding direction of the force receiving structure is designed to protrude toward a side away from other components. While ensuring that the force receiving structure has a sufficient area, the force receiving structure can also avoid interfering with other components during movement, thereby reducing the accident rate. Moreover, this layout optimizes the use of space, makes the use of space in the third direction of the device under test more reasonable, improves the compactness of the device under test, and simplifies the assembly process.

[0044] The three-phase electric energy meter multi-meter position auxiliary probe assembly 10 and the verification device 1 according to the embodiments of the utility model will be described below with reference to Figures 1 to 4 Figure 1 and Figure 2 In some embodiments, the three-phase electric energy meter multi-meter position auxiliary probe assembly 10 and the verification device 1 of the utility model include a probe 100, an electrical connection part 200, and a driven part 300. The probe 100 is used to be inserted into the device to be verified 1 to verify the device to be verified 1. The axis of the probe 100 is arranged parallel to the first direction X, so that the probe 100 can move along the first direction X to perform measurement or contact work. One end of the probe 100 is adapted to be inserted into the device to be verified 1, and the other end of the probe 100 is adapted to be electrically connected to the electrical connection part 200. The electrical connection part 200 extends along the second direction Y, which is perpendicular to the first direction X, so that multiple probes 100 can be arranged along the second direction Y on the electrical connection part 200. The driven part 300 is located on the other side of the electrical connection part 200 away from the probe 100 along the first direction X. The driven part 300 is an interface provided by an external driving structure, for example, an external driving force provided by a cylinder 600, a motor, or other equipment. The cylinder 600 directly acts on the driven part 300, so that the three-phase electric energy meter multi-meter position auxiliary probe assembly 10 moves along the first direction X, and the probe 100 is inserted into or pulled out of the device to be verified 1.

[0045] Figure 2 ​​, the electrical connection portion 200 has a first side and a second side arranged opposite along a third direction Z, the third direction Z, the first direction X and the second direction Y being perpendicular to each other. With reference to 1 and Figure 4 The first side of the electrical connection portion 200 is adapted to be provided with the single-phase electric energy meter multi-meter position auxiliary probe assembly 20, so that the verification device 1 realizes multifunctional integration. The driven portion 300 includes a force receiving structure 310 protruding towards the second side along the third direction Z, and the force receiving structure 310 protrudes towards the second side to avoid the single-phase electric energy meter multi-meter position auxiliary probe assembly 20, thereby avoiding interference between the two to ensure smooth operation of the entire device.

[0046] Specifically, in order to make the driving force more stably act on the driving portion, i.e., to ensure that the probe 100 moves smoothly along the first direction X, it is necessary to provide a larger area of the driven portion 300 to improve the force receiving effect. However, the electrical connection portion 200 extends along the second direction Y, and the driven portion 300 is connected to the electrical connection portion 200, and the electrical connection portion 200 is mainly used for electrical connection of the probe 100, so the thickness of the electrical connection portion 200 is relatively thin, and therefore the surface of the driving portion for bearing the driving force will usually protrude from the electrical connection portion 200 along the thickness direction of the electrical connection portion 200, i.e., the force receiving structure 310 protrudes along the third direction Z. When the three-phase electric energy meter multi-meter position auxiliary probe assembly 10 moves along the first direction X, the protruding force receiving structure 310 is easy to interfere with other components in the verification device 1, resulting in an increase in the accident rate. The present application designs the protruding direction of the force receiving structure 310 to protrude towards the side away from other components, so as to avoid interference between the force receiving structure 310 and other components during movement, thereby reducing the accident rate, and this layout optimizes the space utilization, makes the space utilization of the verification device 1 in the third direction Z more reasonable, improves the compactness of the verification device 1, and simplifies the assembly process.

[0047] In some embodiments, regarding the design of the electrical connection portion 200, in addition to the basic metal conductor, a flexible circuit board (FPC) can also be used as an alternative material. Flexible circuit boards are known for their excellent bending performance, and can easily realize complex shape wiring even in a narrow space. When using a flexible circuit board, not only can the original electrical properties be maintained, but also the flexibility can be used to adjust the shape to better adapt to the interface requirements of different models of electric energy meters. In addition, flexible circuit boards usually have a relatively low thickness, which helps to further compress the overall size and make the product more lightweight and portable.

[0048] In some embodiments, considering the electromagnetic compatibility issues in the actual application environment, a shielding layer can be added around the electrical connection part 200. The shielding layer is made of a metal mesh or foil with good electrical conductivity, which wraps around the electrical connection part 200 and the connected probe 100 part. The benefit of this is that it can effectively block external electromagnetic wave interference, protect internal signals from pollution, and ensure the authenticity and accuracy of measurement data. At the same time, for some high-frequency application scenarios, appropriate shielding measures can also reduce self-radiation, meeting strict EMC standard requirements.

[0049] In some embodiments, for the force receiving structure 310 of the driven part 300, in addition to simple geometric shapes such as rectangular or circular protrusions, it can also be designed in the form of threads or other locking mechanisms. Such improvements can provide users with more accurate operation feedback during manual adjustment, while also increasing the safety and reliability of the connection. For example, by designing a locking mechanism, the user can be provided with feedback on the distance the driven part 300 moves in the first direction X, allowing the user to have a rough estimate of the distance the driven part 300 moves in the first direction X. This facilitates operation and also better prevents over-limit movement.

[0050] In some embodiments, the force receiving structure 310 is made of magnetic material, which can be controlled by an external magnetic field to achieve a non-contact driving method, facilitating remote control in special situations.

[0051] In some embodiments, the driven part 300 can also be equipped with a buffer element, such as a rubber gasket or spring device, to absorb external impact forces and protect the internal circuit from damage. In addition, if considering higher automation application scenarios, the driven part 300 can be equipped with sensors to monitor the size of external forces in real time, and cooperate with the control system to achieve automatic adjustment, further improving the safety and reliability of operation.

[0052] Referring to Figure 2 and Figure 3 In some embodiments, the electrical connection part 200 of the three-phase energy meter multi-meter position auxiliary probe assembly 10 is composed of an upper shell 210, an electrical connection plate 220, and a lower shell 230. The lower shell 230 is provided with a containing groove for containing the electrical connection plate 220, and the upper shell 210 is fixedly connected to the lower shell 230 to form a closed space that safely wraps the electrical connection plate 220 between the upper and lower shells 230. This structure not only protects the internal electrical connection plate 220 from external factors, but also helps maintain good electrical connection quality, ensuring stable and reliable current transmission.

[0053] It can be understood that in some embodiments, the outer shell of the electrical connection part 200, i.e. the upper shell 210 and the lower shell 230, can not only be made of metal materials, but also can be made of non-conductive materials such as plastics and the like. When non-conductive materials are selected, the risk of short circuit can be effectively prevented without affecting normal operation, and the safety of use can be improved.

[0054] With reference to Figure 3 In some embodiments, regarding the design of the electrical connection plate 220, in addition to simply being placed in the accommodation groove, a clamping mechanism such as a screw fastener or a buckle structure can be introduced to ensure that the electrical connection plate 220 is stable and immovable. This can avoid loosening caused by vibration and the like, and thus ensure the stability of the connection under long-term operation. In addition, in order to facilitate maintenance and replacement, the electrical connection plate 220 can be designed in a modular form, each module corresponding to a different functional area, and users can quickly disassemble and assemble specific modules according to actual needs, simplifying the maintenance process and reducing costs.

[0055] In some embodiments, in order to meet the application requirements in special environments, such as humid or dusty environments, the electrical connection part 200 can also increase sealing measures such as O-rings or other forms of sealing gaskets to prevent moisture and dust from entering the inside, protect the internal components from erosion, and prolong the service life.

[0056] With reference to Figure 2 and Figure 3In some embodiments, the driven part 300 of the three-phase meter auxiliary probe assembly 10 is connected to the lower housing 230 in the electrical connection part 200. The driven part 300 includes a force receiving structure 310 protruding in the third direction Z, which protrudes towards the second side and the height of its end in the third direction Z exceeds the height of the upper housing 210. On the one hand, such a design ensures that the force receiving structure 310 does not interfere with the single-phase meter auxiliary probe assembly 20 when it is arranged on the first side, providing sufficient clearance space to allow two different types of auxiliary probe 100 assemblies to coexist in the same device without affecting each other. On the other hand, the driven part 300 is mounted on the lower housing 230, which can improve the structural rigidity of the electrical connection part 200. Specifically, when the driven part 300 has the same size in the third direction Z (i.e., the height direction), if it is arranged on the upper housing 210 and protrudes towards the second side, it will occupy more space. In contrast, when the driven part 300 is located on the lower housing 230 and its protruding part in the third direction Z has the same height as other components on the first side, it can actually achieve a higher protruding height. Therefore, such a layout allows the driven part 300 to withstand greater driving force, thereby making the electrical connection part 200 more stable and reliable. In short, placing the driven part 300 on the lower housing 230 instead of the upper housing 210 can provide a higher protruding height and stronger carrying capacity without increasing the overall height, thereby enhancing the stability and rigidity of the electrical connection part 200.

[0057] Because the height of the force receiving structure 310 exceeds the upper housing 210, not only does it increase the range of space for operation, but it also provides convenience for possible manual adjustments while ensuring a good mechanical transmission path, improving the response efficiency and accuracy of the system.

[0058] It can be understood that in some embodiments, in order to enhance the strength of the force receiving structure 310 and reduce the risk of deformation, methods such as reinforcing materials or increasing thickness can be used to optimize its physical properties. For example, high-strength alloy steel or heat-treated metal materials can be used, which have higher yield strength and wear resistance, and can maintain shape stability under long-term external force.

[0059] In some embodiments, considering that different working environments may be encountered in actual application scenarios, such as humid, corrosive gas, etc., a protective coating such as epoxy paint or other anti-corrosion paint can be applied to the surface of the force receiving structure 310 to improve durability and anti-aging ability. Such protective measures are crucial to prolong the service life of the equipment, especially for electric energy meter detection systems used outdoors or in industrial environments.

[0060] In some embodiments, multiple driven parts 300 can be designed, which are uniformly spaced along the second direction Y on the side of the electrical connection part 200 away from the probe 100. For example, two symmetrical driven parts can be provided on the side of the electrical connection part 200 away from the probe 100, both of which are used to bear driving force, so as to further ensure the stability of the movement of the probe 100 along the first direction X.

[0061] With reference to Figure 2 In some embodiments, the driven part 300 includes a connecting piece 320 connecting the force receiving structure 310 and the lower housing 230 respectively. When viewed along the first direction X, the width of the connecting piece 320 on the side close to the lower housing 230 is greater than the width of the connecting piece 320 on the side close to the force receiving structure 310. This gradual change in width forms a stable support frame, enhancing the rigidity and stability of the overall structure. Specifically, the driven part 300 includes a connecting plate protruding away from the probe 100 along the first direction X, one end of the connecting plate being connected to the lower housing 230, and the other end of the connecting plate being connected to the force receiving structure 310, the force receiving structure 310 protruding from the connecting plate along the third direction Z towards the second side. A link rib plate is provided parallel to the connecting plate, and the outer contour of the connecting piece 320 is arc-shaped, i.e. the connecting piece 320 covers one side of the connecting plate parallel to the first direction X and extends to the lower housing 230. The part of the connecting piece 320 close to the lower housing 230 along the first direction X has a larger area and higher connection strength. Such arc-shaped design not only improves the connection stability of the force receiving structure 310 and the lower housing 230, but also reduces the mass of the connecting piece 320 by eliminating unnecessary area, i.e. the recessed arc-shaped structure design, to leave more space for other components.

[0062] Further, regarding the design of the connecting piece 320, in principle, the wider part can provide a larger contact area, which is beneficial for dispersing the pressure from the force receiving structure 310 and preventing damage caused by local stress concentration; while the narrower part helps to reduce weight without affecting the mechanical properties. This design cleverly balances the demand for strength and lightweight, ensuring sufficient carrying capacity while reducing unnecessary material consumption, embodying the principles of economy and practicality in engineering design. The presence of the connecting piece 320 also strengthens the connection between the driven part 300 and the lower housing 230, ensuring that there is no looseness between the two during the entire operation process. This is very important for maintaining the normal operation of the system, as it is directly related to the reliability of current transmission and the maintenance of the positioning accuracy of the probe 100 components.

[0063] It can be understood that in some embodiments, the material selection of the connecting piece 320 can be adjusted according to different specific application occasions. For applications requiring higher strength, high-performance materials such as titanium alloy, aluminum alloy, etc. can be selected; while for cost-sensitive projects, ordinary steel or plastic can be considered, but it needs to ensure that it has sufficient mechanical strength to meet the use requirements.

[0064] It can be understood that in some embodiments, in order to improve the electrical conductivity of the connecting piece 320, a layer of metal with good electrical conductivity, such as silver, copper, etc. can be plated on its surface. This not only reduces resistance and energy loss, but also improves the quality of electrical connection. In addition, appropriate surface treatment can also play an anti-oxidation role and prolong the service life.

[0065] In some embodiments, elastic elements such as spring sheets or rubber gaskets are embedded inside the connecting piece 320. This can absorb some shocks and impact forces to some extent, protecting the internal circuit from damage. The elastic elements can also serve as fine-tuning, allowing the force-bearing structure 310 to return to its original position after slight deviation, ensuring accurate operation each time and improving the reliability and durability of the system.

[0066] Referring to Figure 2 and Figure 3 In some embodiments, the lower shell 230 of the three-phase electric energy meter multi-meter position auxiliary probe assembly 10 includes a sliding block 233 protruding in the second direction Y. The design of the sliding block 233 allows it to fit the single-phase electric energy meter multi-meter position auxiliary probe assembly 20 and achieve a sliding connection between the two. This structure allows the three-phase and single-phase auxiliary probe 100 assemblies to coexist and work together in the same device while ensuring operational flexibility.

[0067] Specifically, the presence of the sliding block 233 provides mechanical guidance, ensuring that the three-phase electric energy meter multi-meter position auxiliary probe assembly 10 can move smoothly along a predetermined path relative to the single-phase electric energy meter multi-meter position auxiliary probe assembly 20. This not only simplifies the installation process, but also improves work efficiency and reduces errors caused by improper manual adjustment. In addition, the contact surface between the sliding block 233 and the single-phase electric energy meter multi-meter position auxiliary probe assembly 20 should be designed with low-friction materials or surface treatment to reduce wear and prolong service life.

[0068] It can be understood that in some embodiments, in order to enhance the functionality and adaptability of the sliding block 233, a limiting mechanism such as a flexible stopper or a buckle device can be added to the sliding block 233. These additional components can lock the position of the three-phase electric energy meter multi-meter position auxiliary probe assembly 10 when not in use, preventing accidental movement; while when the position needs to be adjusted, it can be unlocked by simple operation, allowing the sliding block 233 to slide freely. This design not only ensures the stability of the work, but also facilitates the user's daily operation.

[0069] In some embodiments, the slider 233 can also be designed in an adjustable form. For example, the extension length of the slider 233 is fine-tuned by screws or other fasteners to adapt to single-phase electric energy meter multi-meter position auxiliary probe assembly 20 of different sizes. Such design flexibility makes the entire system more versatile and suitable for a variety of models of electric energy meter detection equipment, thereby expanding the scope of application of the product.

[0070] In some embodiments, in order to improve the durability and reliability of the slider 233, wear-resistant and corrosion-resistant materials such as stainless steel and engineering plastics can be selected to manufacture the slider 233. In some cases, a layer of lubricant can also be coated on the surface of the slider 233 or self-lubricating materials can be used to further reduce the friction coefficient and ensure long-term stable operation.

[0071] Referring to Figure 2 and Figure 3 In some embodiments, the lower shell 230 of the three-phase electric energy meter multi-meter position auxiliary probe assembly 10 is provided with a positioning structure 232 towards the upper shell 210. The positioning structure 232 is used to cooperate with the first positioning groove 211 on the upper shell 210 and the second positioning groove 231 on the electric connection plate 220. When the assembly is assembled, the positioning structure 232 is inserted into the two positioning grooves in the first direction X, forming an accurate positioning effect. This structure ensures the accuracy of the relative position between the components, thereby ensuring the quality and stability of the electrical connection.

[0072] Regarding the height variation of the positioning structure 232, that is, gradually increasing from the side close to the probe 100 to the side away from the probe 100, which helps to guide the correct alignment of the upper and lower shells 230 and the electric connection plate 220, avoiding misalignment problems that may occur during assembly. The gradual height design also increases the firmness of the positioning, which is not easy to come off even under external impact, maintaining good electrical connection performance.

[0073] In some embodiments, in addition to conventional metal materials, non-metal materials with good elasticity such as nylon or polyformaldehyde resin can also be considered for the material selection of the positioning structure 232. Such materials can provide a self-locking function to some extent, that is, they can still maintain a close-fitting state under slight vibration or external force, enhancing the overall stability of the system. At the same time, non-metal materials generally have lower electrical conductivity, which helps to prevent short circuit risks and improves safety in use.

[0074] In order to further improve the positioning accuracy, a small texture or groove can be provided on the surface of the positioning structure 232 to increase the friction and prevent slipping. In addition, visual identification marks such as color coding or barcodes can also be introduced to help robots on the automated assembly line accurately identify the positioning point, improving production efficiency.

[0075] In some embodiments, a certain amount of gap compensation can be reserved between the positioning structure 232 and the positioning slot, or a design that is easy to replace can be adopted, to ensure that high positioning accuracy can be maintained even after multiple disassembly and assembly. This method effectively solves the problem that traditional fixed positioning is prone to failure due to wear, and improves the reliability and durability of the system.

[0076] Referring to Figure 2 and Figure 3 In some embodiments, the height of the positioning structure 232 in the three-phase electric energy meter multi-table auxiliary probe assembly 10 along the first direction X gradually increases from the side close to the probe 100 to the side away from the probe 100. The positioning structure 232 is provided on the lower shell 230 and protrudes towards the upper shell 210. At the same time, the upper shell 210 is provided with a first positioning slot 211 extending along the first direction X, and the electric connection plate 220 is provided with a second positioning slot 231 extending along the same direction. When the assembly is assembled, the positioning structure 232 will be inserted into the two positioning slots to form a stable mechanical connection. Specifically, the lower part close to the probe 100 first contacts the positioning slot, and as the insertion depth increases, the height of the positioning structure 232 also increases accordingly, thereby providing a tighter fit. This process not only improves the positioning accuracy, but also enhances the stability and reliability of the entire assembly, ensuring the quality of electrical connection.

[0077] It can be understood that, in some embodiments, in order to further improve the positioning accuracy and assembly efficiency, a guide slope or chamfer treatment can be added to the surface of the positioning structure 232. These designs help to reduce the resistance during assembly, making it easier for the positioning structure 232 to enter the positioning slot, while also reducing the risk of damage caused by collision. In addition, a small elastic buckle can also be provided at the end of the positioning structure 232 to achieve a self-locking function, preventing the assembly from loosening during use.

[0078] Referring to Figure 2 and Figure 3In some embodiments, the three-phase electric energy meter multi-site auxiliary probe assembly 10 includes a three-phase strong current auxiliary probe 100 group socket and a three-phase weak current auxiliary probe 100 group socket. Both the three-phase strong current auxiliary probe 100 group socket and the three-phase weak current auxiliary probe 100 group socket are connected to the side of the electrical connection part 200 away from the probe 100, i.e. arranged in a position away from the probe 100 along the first direction X. Such a layout design makes the strong current and weak current parts operate independently without interference, while maintaining compact space utilization, adapting to various testing needs. Specifically, the three-phase strong current auxiliary probe 100 group socket is used to connect higher voltage level circuits, and the three-phase weak current auxiliary probe 100 group socket is used to connect low voltage signal lines. The physical isolation between the two not only reduces the possibility of electromagnetic interference, but also improves the safety and stability of the system. In addition, since they are both located on the side of the electrical connection part 200 away from the probe 100, it is convenient for centralized management and maintenance, simplifying wiring and debugging work.

[0079] It can be understood that, in some embodiments, in order to enhance safety protection measures, an insulating protective cover can be provided around the three-phase strong current auxiliary probe 100 group socket, made of fireproof and high-temperature resistant materials, effectively preventing accidental electric shock accidents. For the weak current part, a filter or surge protection device can be integrated to resist external electromagnetic interference and transient voltage fluctuations, ensuring the integrity of signal transmission.

[0080] In some embodiments, clear markings or color coding are provided between the two sockets to help users quickly identify the correct connection position. For example, red markings are used to represent strong current sockets, and green markings are used to represent weak current sockets, guiding correct operation through visual cues and avoiding potential problems caused by misoperation. In addition, LED indicator lights can also be added inside the socket to display the current working state (such as on-off), facilitating user monitoring of device operation.

[0081] In some embodiments, in order to optimize space utilization, additional functional units such as data acquisition modules, wireless communication modules, etc. can be integrated on the electrical connection part 200, enabling the three-phase electric energy meter multi-site auxiliary probe assembly 10 to have more additional value. These functional units can be directly connected to the strong current or weak current sockets, realizing multifunctional integrated design and meeting the higher requirements of modern smart grids for electric energy meter detection systems.

[0082] Referring to Figure 2 and Figure 3 In some embodiments, the three-phase strong current auxiliary probe 100 group socket and the three-phase weak current auxiliary probe 100 group socket of the three-phase electric energy meter multi-site auxiliary probe assembly 10 are arranged apart along the second direction Y. By separating the strong current and weak current sockets, electromagnetic interference between the two can be effectively reduced, ensuring the purity of signal transmission and improving the safety and stability of the system.

[0083] This spaced arrangement not only helps with physical isolation, but also provides independent operating space for each socket, facilitating maintenance and repair. For example, when testing or adjusting a specific type of circuit is required, the operator can directly access the corresponding socket without affecting the working state of other parts. In addition, such a layout is also beneficial for heat dissipation management, as there is enough space between the two sockets to promote air circulation, reducing the risk of overheating.

[0084] It can be understood that in some embodiments, in order to further optimize the effect of the spaced arrangement, a shielding plate or isolation wall can be provided between the strong current and weak current sockets. These additional structures are made of non-conductive materials such as plastic or ceramic, which can enhance the electrical isolation effect and prevent any possible short circuit risk. The shielding plate can also integrate additional functions such as built-in temperature sensors to monitor real-time environmental temperature changes and ensure that the device operates within the appropriate working range.

[0085] In some embodiments, the spacing distance of the sockets can be flexibly adjusted according to actual use to meet the needs of different application scenarios. For example, in high-density installation environments, the space utilization rate can be maximized by fine-tuning the socket positions; while in open laboratories, the spacing can be appropriately increased to facilitate wiring and inspection. In addition, for some special purposes such as explosion-proof areas, the sockets should be designed in a completely sealed form, and the spacing between them must meet the requirements of relevant safety standards.

[0086] In some embodiments, the three-phase strong current auxiliary probe 100 socket group and the three-phase weak current auxiliary probe 100 socket group are designed as independent modules, each of which can be individually disassembled, replaced or upgraded. This design not only simplifies production and maintenance processes, but also allows users to customize their own auxiliary probe 100 component configuration according to specific needs. Modular design also makes future technology updates easier to implement, simply by replacing the corresponding modules without the need to rebuild the entire system.

[0087] Referring to Figure 1 Embodiments of the second aspect of the present application propose a verification device 1. The verification device 1 includes the three-phase electric energy meter multi-table position auxiliary probe assembly 10 and the single-phase electric energy meter multi-table position auxiliary probe assembly 20 of any of the above embodiments. Referring to Figure 1 and Figure 4, the three-phase electric energy meter multi-meter position auxiliary probe assembly 10 is located above. The single-phase electric energy meter multi-meter position auxiliary probe assembly 20 comprises a sliding rail extending along the first direction X, and the three-phase electric energy meter multi-meter position auxiliary probe assembly 10 is slidably connected to the single-phase electric energy meter multi-meter position auxiliary probe assembly 20 below through the sliding block 233, so that the three-phase electric energy meter multi-meter position auxiliary probe assembly 10 and the single-phase electric energy meter multi-meter position auxiliary probe assembly 20 can slide relative to each other along the first direction X, so that the detection device 1 is compatible with the detection of single-phase electric energy meters and the detection of three-phase electric energy meters. Specifically, the single-phase electric energy meter multi-meter position auxiliary probe assembly 20 is provided with a plurality of three-phase strong electric auxiliary probe 100 group sockets, a plurality of three-phase strong electric auxiliary probe 100 group sockets respectively corresponding to a plurality of wiring ports and a plurality of wiring ports for single-phase electric energy meters, and the three-phase strong electric auxiliary probe 100 group sockets of the three-phase electric energy meter multi-meter position auxiliary probe assembly 10 of the present application are respectively connected to the corresponding wiring ports of the single-phase electric energy meter multi-meter position auxiliary probe assembly 20 through flexible wires, so as to realize the independent movement of the three-phase electric energy meter multi-meter position auxiliary probe assembly 10 and the single-phase electric energy meter multi-meter position auxiliary probe assembly 20, and the external three-phase electric energy meter multi-meter position auxiliary probe assembly 10 has formed a current loop with the single-phase electric energy meter multi-meter position auxiliary probe assembly 20 through the wires. The external circuit only needs to be connected to the wiring ports of the single-phase electric energy meter multi-meter position auxiliary probe assembly 20, and then the three-phase electric energy meter multi-meter position auxiliary probe assembly 10 can be connected, and then the detection of the to-be-detected device 1 can be realized after the probe 100 of the three-phase electric energy meter multi-meter position auxiliary probe assembly 10 is inserted into the to-be-detected device 1.

[0088] Further, this stacking design makes full use of the vertical space, realizes a compact layout, and adapts to limited installation environment. The presence of the sliding rail provides mechanical guidance, ensuring that the three-phase electric energy meter multi-meter position auxiliary probe assembly 10 can smoothly move relative to the single-phase electric energy meter multi-meter position auxiliary probe assembly 20 along the predetermined path, simplifying the installation process and improving work efficiency. The sliding rail is used in cooperation with the sliding block 233 to ensure good sliding performance and reduce errors caused by improper manual adjustment. Moreover, the force receiving structure 310 of the three-phase electric energy meter multi-meter position auxiliary probe assembly 10 protrudes towards the second side to avoid the single-phase electric energy meter multi-meter position auxiliary probe assembly 20, thereby reducing the probability of accidents caused by positional interference.

[0089] In some embodiments, a buffer device such as a spring or rubber pad is provided at the end of the sliding rail. This can play a buffering role when the three-phase electric energy meter multi-meter position auxiliary probe assembly 10 reaches the limit position, avoiding damage caused by hard collision. The buffer device can also absorb vibration and impact force, protecting internal circuits and mechanical components from damage, and improving the reliability and durability of the system.

[0090] In some embodiments, in order to simplify the assembly process and improve production efficiency, a pre-assembled manner can be adopted. That is, the three-phase electric energy meter multi-meter position auxiliary probe assembly 10 and the single-phase electric energy meter multi-meter position auxiliary probe assembly 20 are pre-assembled as a whole unit, and then they are installed into the bearing platform of the verification device 1 as a complete assembly. This way not only can reduce the on-site installation steps, but also can ensure the precise cooperation between the components, and improve the quality of the final product.

[0091] The above are only preferred embodiments of the present application, and do not limit the patent range of the present application, and any equivalent structural transformation made by utilizing the content of the present application specification and drawings, or directly / indirectly applied in other related technical fields under the utility model concept of the present application are included in the patent protection range of the present application.
