Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of electric energy meter calibration, especially to a kind of auxiliary probe subassembly and calibrating device for single-phase electric energy meter. BACKGROUND

[0002] In modern industrial detection and calibration, the device to be calibrated is detected by the calibrating device to ensure the precision and reliability of the electrical and electronic equipment of the device to be calibrated. The core components of the calibrating device include probes, sockets and driving mechanisms. The probe, as a component directly contacting the device to be calibrated, is connected to the calibrating device body and inserted into the device to be calibrated under the control of the driving mechanism to accurately measure or calibrate the device to be calibrated.

[0003] However, in the existing design of the calibrating device, in order to provide sufficient space for the probe, the socket is arranged on the side of the calibrating device body away from the probe, and the driving mechanism cannot be compactly arranged with the probe and is usually placed at the rear end of the socket. This layout causes a series of problems. First, it increases the overall longitudinal size of the calibrating device, making the device larger in volume. This not only increases the material and manufacturing costs, but also makes the device more inconvenient to transport and install. Second, since the driving mechanism occupies the space behind the socket, the design of the prior art requires that sufficient space be reserved behind the socket to accommodate the driving mechanism, which makes the utilization of the internal space of the calibrating device unreasonable, reduces the space utilization, increases the structural complexity, and affects the overall performance and convenience of the device. SUMMARY

[0004] The main purpose of the utility model is to provide an auxiliary probe subassembly and calibrating device for single-phase electric energy meter, which can improve the space utilization.

[0014] The electrical connection part further comprises a single-phase strong-current auxiliary probe assembly socket, a three-phase strong-current auxiliary probe assembly socket, a single-phase weak-current auxiliary probe assembly socket and a three-phase weak-current auxiliary probe assembly socket, and the probe is electrically connected to the electrical connection plate, and the single-phase strong-current auxiliary probe assembly socket, the three-phase strong-current auxiliary probe assembly socket, the single-phase weak-current auxiliary probe assembly socket and the three-phase weak-current auxiliary probe assembly socket are arranged on the electrical connection plate.

[0015] In some embodiments, in the third direction, the electrical connection plate is located between the upper shell and the lower shell, and the first direction, the second direction and the third direction are perpendicular to each other.

[0016] In some embodiments, the lower shell is concave and has a receiving groove corresponding to the electrical connection plate, and the electrical connection plate is arranged in the receiving groove.

[0017] In some embodiments, in the first direction, the distance that the upper shell extends in the direction away from the probe of the body part is shorter than the distance that the electrical connection plate extends in the direction away from the probe of the body part, so that the sockets of the single-phase strong-current auxiliary probe assembly socket, the three-phase strong-current auxiliary probe assembly socket, the single-phase weak-current auxiliary probe assembly socket and the three-phase weak-current auxiliary probe assembly socket are all exposed.

[0022] The auxiliary probe assembly of the single-phase electric energy meter comprises a probe, an electrical connection portion, and a driven portion. The axis of the probe is parallel to the first direction, and the probe is used for being inserted into a corresponding jack of an electric energy meter for electrical connection. The electrical connection portion comprises a main body portion, a first arm, and a second arm, wherein the probe is connected to one end of the main body portion, and the main body portion serves as the core structure of the entire electrical connection portion and is responsible for connecting the probe with subsequent circuits. The second direction is perpendicular to the first direction, and along the second direction, the first arm and the second arm are located on opposite sides of the main body portion, and the first arm and the second arm extend along the first direction away from the side of the main body portion facing away from the probe, forming a stable support structure. The driven portion is arranged between the first arm and the second arm and is connected to the side of the electrical connection portion facing away from the probe.

Specifically, the driven portion is arranged between the first arm and the second arm, and the first arm and the second arm extend along the first direction away from the side of the main body portion facing away from the probe, so that the position design of the driven portion of the present application can save space along the first direction, compared with the driven portion being arranged on the side of the first arm facing away from the probe along the first direction or the driven portion being arranged on the side of the second arm facing away from the probe along the first direction.

[0023] Further, the first arm and the second arm have occupied a large amount of space of the auxiliary probe assembly along the first direction, and if the driven portion is further arranged on the side of the first arm and the second arm facing away from the probe along the first direction, the first arm and the driven portion and / or the second arm and the driven portion further occupy a larger space along the first direction, resulting in unreasonable space utilization and low space utilization rate. In the present application, the driven portion is arranged between the first arm and the second arm and is connected to the main body portion. Even if the driven portion extends along the first direction, the size of the end of the driven portion to the main body portion in the first direction can still save the size of the first arm and / or the second arm along the first direction, so that the design of the present application makes the size of the auxiliary probe assembly in the first direction shorter, the space design in the first direction more reasonable, and the space utilization rate higher.

[0043] The auxiliary probe assembly 10 for a single-phase electric energy meter according to the embodiments of the utility model will be described below with reference to Figures 1 to 3

[0044] With reference to Figure 1 In some embodiments, the auxiliary probe assembly 10 for a single-phase electric energy meter of the present application comprises a probe 100, an electrical connection part 200 and a driven part 300. The axis of the probe 100 is parallel to the first direction X, and the probe 100 is used to be inserted into the corresponding jack of the electric energy meter for electrical connection.

[0045] ​The electrical connection part 200 includes a main body part 210, a first arm 220 and a second arm 230, wherein the probe 100 is connected to one end of the main body part 210, and the main body part 210 serves as the core structure of the entire electrical connection part 200, responsible for connecting the probe 100 with subsequent circuits. The second direction Y is perpendicular to the first direction X, along the second direction Y, the first arm 220 and the second arm 230 are respectively located on the opposite sides of the main body part 210, and the first arm 220 and the second arm 230 extend along the first direction X to the side of the main body part 210 away from the probe 100, forming a stable support structure. Such design on the one hand avoids the probe 100 enough space, facilitates the circuit design, on the other hand guarantees the overall rigidity of the electrical connection part 200.

[0046] The driven part 300 is arranged between the first arm 220 and the second arm 230 and is connected to the side of the electrical connection part 200 away from the probe 100. The role of the driven part 300 is to drive the entire auxiliary probe assembly to move or rotate under the action of external force, so as to realize the precise docking of the probe 100 with other components. The driven part 300 can provide sufficient torque when operating, ensuring that the probe 100 is accurately inserted into the designated position of the electric energy meter, improving the installation efficiency and accuracy. Referring to Figure 1 In some embodiments, the driving part is provided with a T-shaped slot 310 to facilitate the docking of the driving structure 700 such as air cylinder.

[0047] Specifically, the driven part 300 is arranged between the first arm 220 and the second arm 230, and the first arm 220 and the second arm 230 both extend away from the side of the main body part 210 of the probe 100 along the first direction X. Therefore, compared with the case that the driven part 300 is arranged on the side of the first arm 220 away from the probe 100 along the first direction X or on the side of the second arm 230 away from the probe 100 along the first direction X, the position of the driven part 300 of the present application can save space along the first direction X. To further explain the beneficial effects of the driven part 300 of the present application, specifically, the first arm 220 and the second arm 230 have already occupied a large amount of space of the auxiliary probe assembly along the first direction X. If the driven part 300 is arranged on the side of the first arm 220 and the second arm 230 away from the probe 100 along the first direction X, the first arm 220 and the driven part 300 and / or the second arm 230 and the driven part 300 will further occupy more space along the first direction X, resulting in unreasonable space utilization and low space utilization rate. In the present application, the driven part 300 is arranged between the first arm 220 and the second arm 230, and the driven part 300 is connected to the main body part 210. Even if the driven part 300 extends along the first direction X, the size of the end of the driven part 300 to the main body part 210 along the first direction X can still save the size of the first arm 220 and / or the second arm 230 along the first direction X. Therefore, the design of the present application makes the size of the auxiliary probe assembly along the first direction X shorter, and the space design along the first direction X more reasonable, thereby improving the space utilization rate.

[0048] It can be understood that the first arm 220 and the second arm 230 not only play a supporting role, but also are used for arranging the terminal. The extension of the first arm 220 and the second arm 230 along the first direction X can make the terminal and other modules farther away from the probe 100, thereby facilitating the design of the wire. The first arm 220 and the second arm 230 can be plate-shaped or arc-shaped structures. The first arm 220 and the second arm 230 only need to protrude away from the probe 100, and the size thereof along the first direction X and the size thereof along the second direction Y are irrelevant. The design purpose of the present application is to make the driven part 300 avoid these protruding parts along the first direction X, and be connected to the probe 100 in a relatively close manner along the first direction X, thereby shortening the distance from the end of the probe 100 to the side of the driven part 300 away from the probe 100, i.e., shortening the size of the auxiliary probe assembly affected by the driving part along the first direction X, thereby improving the space utilization rate. In summary, the driven part 300 of the present application is designed between the first arm 220 and the second arm 230, thereby avoiding these protruding structures along the first direction X, so as to achieve the purpose of improving the space utilization rate of the auxiliary probe assembly.

[0049] It can be understood that, in some embodiments, for the probe 100 part, considering that there may be differences in the sizes of the power meter jacks of different models, the probe 100 can adopt an adjustable design, that is, a threaded or other adjustment mechanism is arranged at the end thereof, allowing the user to adjust the length of the probe 100 according to actual needs, to adapt to more types of power meters.

[0050] In some embodiments, for the first arm 220 and the second arm 230 in the electrical connection part 200, they not only play a supporting role, but also can integrate additional functional modules. For example, a micro sensor is embedded in the first arm 220, for real-time monitoring of the contact state of the probe 100 and the parameter change conditions such as current and voltage, to provide more detailed data feedback for the user; or an indicator light device is additionally arranged on the second arm 230, which automatically lights up when the probe 100 is correctly inserted, prompting the operator to complete the task.

[0051] In some embodiments, regarding the driven part 300, in addition to the basic driving function, a non-slip washer or rubber sleeve or the like material covering surface can be considered to be added, to increase the friction and also to protect the surface of the device from being scratched. In addition, if the application scenario involves frequent disassembly and assembly, magnetic materials can be arranged around the driven part 300, to use the magnetic field attraction force to fix the probe assembly, to reduce the risk of loosening caused by vibration.

[0052] Referring to Figure 1 In some embodiments, the auxiliary probe assembly 10 for a single-phase power meter includes two driven parts 300, which are connected to the side of the main body part 210 away from the probe 100 along the first direction X, and are connected to the side of the first arm 220 facing the second arm 230 and the side of the second arm 230 facing the first arm 220 along the second direction Y. On the one hand, through the cooperation of the two driven parts 300, the main body part 210 can be uniformly stressed, so that the probe 100 moves more stably along the first direction X; on the other hand, such a design allows both driven parts 300 to be close to the middle position of the main body part 210, thereby facilitating the stable driving of the main body part 210 along the first direction X; finally, the two driven parts 300 are connected to the first arm 220 and the second arm 230, respectively, which is compact in structure and can improve the mechanical rigidity of the auxiliary probe assembly as a whole.

[0053] In some embodiments, when the power meter needs to be tested or maintained, the probe 100 can be moved by separately operating one side of the driven part 300, avoiding the deviation problem that may be caused by the traditional single-point driving. Moreover, since the distance between the two driven parts 300 is relatively close, multi-angle adjustment can be easily realized even in the case of limited space, greatly expanding the application range.

[0054] The design of the two driven parts 300 increases the operation dimension, making the probe assembly flexible to use in more complex environments; at the same time, it also provides the possibility of automated assembly, because the robot hand can trigger the two driven parts 300 on both sides simultaneously or sequentially according to the preset program to complete precise positioning.

[0055] In some embodiments, to enhance the operational convenience and safety of the auxiliary probe assembly, an intelligent control system can be introduced based on the double driven part 300. On the one hand, a microprocessor and a wireless communication module can be built into each driven part 300, allowing them to receive instructions from an external controller and perform corresponding actions. For example, by using a mobile phone APP to remotely control the position adjustment of the probe assembly, a non-contact operation process can be realized, which is particularly suitable for work scenarios in dangerous environments.

[0056] In some embodiments, considering that unexpected situations may occur during actual use, such as sudden power failure or signal interference, an emergency locking mechanism can be added to the driven part 300. Once an abnormal condition is detected, the current state is immediately locked to prevent the probe 100 from falling off accidentally and causing damage. In addition, each driven part 300 can be equipped with an independent power source (such as a small battery) to ensure that even if the main power fails, it can maintain basic functions for a period of time, ensuring the smooth completion of the task. Such a design not only improves the robustness of the system, but also brings users a more secure and reliable user experience.

[0057] Referring to Figure 1 In some embodiments, the electrical connection part 200 of the auxiliary probe assembly 10 for single-phase electric energy meters includes a single-phase strong current auxiliary probe assembly socket 221, a three-phase strong current auxiliary probe assembly socket 222, a single-phase weak current auxiliary probe assembly socket 231, and a three-phase weak current auxiliary probe assembly socket 232. These sockets are used for different types of power signal transmission to adapt to the needs of various application scenarios. Specifically, the single-phase strong current auxiliary probe assembly socket 221 and the three-phase strong current auxiliary probe assembly socket 222 are arranged on the first arm 220, while the single-phase weak current auxiliary probe assembly socket 231 and the three-phase weak current auxiliary probe assembly socket 232 are located on the second arm 230.

[0058] Such a layout ensures electrical isolation between different types of sockets, preventing interference between strong current and weak current, thereby improving the safety and reliability of the system. At the same time, this distribution makes installation more convenient, because users can choose the appropriate location for connection according to actual needs without worrying about conflicts between different types of power sources.

[0059] In some embodiments, considering the influence of dust or moisture in the working environment, waterproof and dustproof covers can be added outside each socket. When not in use, the covers are closed to protect the internal contacts from contamination; when access to cables or other equipment is needed, the covers are opened for operation. This not only prolongs the service life of the socket, but also enhances the overall safety performance.

[0060] In some embodiments, micro sensors are embedded inside the socket to monitor the current intensity and voltage level in real time and transmit data to the central control system. Once abnormal conditions such as overload or short circuit are detected, the system will immediately alert maintenance personnel to take action. In addition, remote monitoring can be achieved by combining Internet of Things technology, allowing users to monitor device status anytime, anywhere and respond in a timely manner.

[0061] In some embodiments, in order to make the assembly more flexible to cope with different measurement tasks, a modular design concept can be adopted. That is, each socket unit can be independently disassembled and replaced, and freely combined into the required configuration according to specific needs. For example, in some cases only single-phase strong current auxiliary probe group socket 221 is needed, then only this part is retained, and the rest can be temporarily removed, reducing unnecessary resource waste.

[0062] Referring to Figure 1 In some embodiments, along the second direction Y, the three-phase strong current auxiliary probe group socket 222 is arranged on the side of the first arm 220 facing the second arm 230, and the single-phase strong current auxiliary probe group socket 221 is arranged on the side of the first arm 220 away from the second arm 230; correspondingly, the three-phase weak current auxiliary probe group socket 232 is arranged on the side of the second arm 230 facing the first arm 220, and the single-phase weak current auxiliary probe group socket 231 is arranged on the side of the second arm 230 away from the first arm 220. Such an arrangement ensures sufficient spacing between different types of sockets, avoiding electromagnetic interference between them, and also facilitates wiring and connection operations.

[0063] Specifically, by arranging the positions of different types of sockets, an orderly and reasonable spatial layout is formed. This not only effectively reduces the problem of signal crosstalk caused by too close distance, but also provides convenient conditions for subsequent maintenance, because each socket has a clear position mark, easy to identify and operate. In addition, this layout is also beneficial to heat dissipation, keeping each component within a suitable working temperature range.

[0064] In some embodiments, the auxiliary probe assembly of the three-phase electric energy meter can be directly electrically connected to the three-phase strong electric auxiliary probe group socket 222 and the three-phase weak electric auxiliary probe group socket 232 through wires. Since the three-phase strong electric auxiliary probe group socket 222 and the three-phase weak electric auxiliary probe group socket 232 are both arranged on the inner side of the first arm 220 and the second arm 230, this structure is conducive to the arrangement and wiring of the auxiliary probe assembly of the three-phase electric energy meter. Of course, the flexible connection of the auxiliary probe assembly of the three-phase electric energy meter through wires is conducive to adjusting the relative position of the auxiliary probe assembly 20 for the three-phase electric energy meter and the auxiliary probe assembly 10 for the single-phase electric energy meter, so that they do not interfere with each other during work. The above structure is arranged in the same calibration device, so that the calibration device has the ability to calibrate single-phase electric energy meters and three-phase electric energy meters.

[0065] In some embodiments, fine-tuning of the position of the socket can also be considered to make it more in line with the principles of ergonomics. For example, placing the most commonly used socket in the most easily accessible place to reduce the operator's fatigue. In addition, a clear sign can be added to each socket to indicate its purpose and related parameter information, helping users to quickly and accurately find the required interface and improve work efficiency.

[0066] In some embodiments, the single-phase strong electric auxiliary probe group socket 221, the three-phase strong electric auxiliary probe group socket 222, the single-phase weak electric auxiliary probe group socket 231 and the three-phase weak electric auxiliary probe group socket 232 of the present application can be configured as multifunctional composite sockets. Specifically, the multifunctional composite socket integrates multiple interface forms, supporting not only traditional alternating current input, but also USB charging, RS485 communication and other functions. In this way, not only is the wiring connection process simplified, but also more diversified application requirements are met. For example, during on-site debugging, technicians can directly use the composite socket to complete multiple tasks without the need to frequently change tools or adjust settings, greatly improving work efficiency.

[0067] Reference Figure 1In some embodiments, the single-phase strong-current auxiliary probe group socket 221 and the three-phase strong-current auxiliary probe group socket 222 are both arranged on the side of the first arm 220 away from the probe 100. The single-phase weak-current auxiliary probe group socket 231 and the three-phase weak-current auxiliary probe group socket 232 are arranged on the side of the second arm 230 away from the probe 100. This arrangement can effectively prevent electromagnetic interference between the strong-current and weak-current sockets, ensuring the stability and accuracy of signal transmission. In addition, such a design also facilitates users to select the appropriate interface for connection according to actual needs, simplifying the operation process and improving work efficiency. Furthermore, the single-phase strong-current auxiliary probe group socket 221, the three-phase strong-current auxiliary probe group socket 222, the single-phase weak-current auxiliary probe group socket 231, and the three-phase weak-current auxiliary probe group socket 232 are all arranged away from the probe 100, leaving enough space between them and the probe 100 for wiring.

[0068] Referring to Figure 1 and Figure 2 In some embodiments, the electrical connection part 200 of the auxiliary probe assembly 10 for single-phase electric energy meters includes an upper housing 400, an electrical connection board 500, and a lower housing 600. The first arm 220 and the second arm 230 are respectively configured as the corresponding protruding parts of the upper housing 400, the electrical connection board 500, and the lower housing 600 along the first direction X away from the probe 100, and the main body part 210 is located between the first arm 220 and the second arm 230. The probe 100 is directly electrically connected to the electrical connection board 500, and all types of auxiliary probe group sockets (including the single-phase strong-current auxiliary probe group socket 221, the three-phase strong-current auxiliary probe group socket 222, the single-phase weak-current auxiliary probe group socket 231, and the three-phase weak-current auxiliary probe group socket 232) are installed on the electrical connection board 500. Along the third direction Z, the electrical connection board 500 is located between the upper housing 400 and the lower housing 600, forming a compact and stable structure, and the first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0069] This design achieves effective connection of the probe 100 with various types of auxiliary probe group sockets, ensuring the continuity and reliability of power transmission. The electrical connection board 500, as the core component, centrally bears all electrical connection points, simplifying internal wiring and reducing failure rates. The electrical connection board 500 is arranged between the upper housing 400 and the lower housing 600, with its main part being covered by the upper housing 400 and the lower housing 600. This design not only provides good mechanical protection for the electrical connection board 500 but also effectively shields external electromagnetic interference, ensuring stable operation of the system.

[0070] In some embodiments, considering that there are many sockets on the electric connection plate 500, it may cause the local area to be too crowded, affecting the heat dissipation effect. Therefore, the layout of the circuit can be reasonably planned inside the electric connection plate 500, and a multi-layer circuit board design can be used to disperse the heat source, ensuring that each socket can obtain sufficient ventilation cooling. In addition, a dedicated heat dissipation channel or fan device can be provided in the lower shell 600 to accelerate air circulation and maintain a suitable working temperature.

[0071] In some embodiments, in order to facilitate on-site installation and debugging, a quick plug connector can be added between the electric connection plate 500 and each socket. This way allows users to complete the installation and disassembly of the socket without tools, greatly shortening the preparation time. In this way, technicians can quickly adjust the configuration to adapt to new measurement requirements.

[0072] Referring to Figure 1 and Figure 2 In some embodiments, the lower shell 600 of the auxiliary probe assembly 10 for a single-phase electric energy meter is designed with a recessed accommodation groove corresponding to the electric connection plate 500 for installing and fixing the electric connection plate 500. This structure ensures that the electric connection plate 500 can be stably embedded in the lower shell 600, thereby enhancing the mechanical strength and stability of the entire electric connection part 200. The electric connection plate 500 is arranged in a sunken manner in the lower shell 600, which facilitates the design of the electric connection plate 500 upper surface and the lower shell 600 upper surface flush structure, thereby facilitating the design of the matching upper shell 400, making the surface of the entire shell structure regular and compact. In addition, by placing the electric connection plate 500 in the accommodation groove, the electric connection plate 500 can be effectively protected from external environmental factors such as dust and moisture, improving the durability and reliability of the system. At the same time, since the electric connection plate 500 is completely wrapped between the upper shell 400 and the lower shell 600, a good electromagnetic shielding effect is formed, reducing the influence of external interference on the circuit operation and ensuring the quality of signal transmission.

[0073] In some embodiments, considering that heat may be generated on the electric connection plate 500, heat dissipation fins or micro fans can be provided at the bottom or sidewall of the accommodation groove. These devices help quickly dissipate the heat generated by the electric connection plate 500, keeping it within the appropriate operating temperature range, thereby prolonging the service life and improving performance.

[0074] In some embodiments, a layer of soft and elastic cushioning material such as rubber pad or foam is added between the accommodation groove and the electric connection plate 500. This layer of material not only absorbs shocks and reduces the risk of damage caused by external impact, but also plays a certain sealing role to prevent moisture or other contaminants from entering the electric connection plate 500 area.

[0075] In some embodiments, in order to make each socket unit on the electrical connection plate 500 more easily maintained and replaced, a modular design concept can be adopted. That is, each socket unit can be independently detached and has a standardized interface, facilitating users to flexibly adjust the configuration as needed. This not only simplifies the maintenance process, but also increases the adaptability of the product.

[0076] With reference to Figure 1 and Figure 2 In some embodiments, in the first direction X, the upper shell 400 extends in the direction away from the probe 100 side of the main body 210, and the distance is shorter than the distance that the electrical connection plate 500 extends in the direction away from the probe 100 side of the main body 210, so that the sockets of the single-phase strong current auxiliary probe group socket 221, the three-phase strong current auxiliary probe group socket 222, the single-phase weak current auxiliary probe group socket 231 and the three-phase weak current auxiliary probe group socket 232 are exposed, facilitating user operation. Specifically, the shorter upper shell 400 does not block the socket of any socket, while the longer electrical connection plate 500 provides sufficient support and positioning space for the socket, ensuring the safety and reliability of electrical connection.

[0077] By reasonably planning the relative length relationship between the upper shell 400 and the electrical connection plate 500, the maximum exposure of the socket socket is realized. Not only is the design structure simple and easy to produce and process, but also greatly improves the user's convenience. Users can easily connect or disconnect cables without additional tools, simplifying the on-site debugging and daily maintenance process. In addition, such a layout also helps visual inspection, making it easier for technicians to find potential problems and take corrective action in a timely manner.

[0078] In some embodiments, considering the safety requirements in actual application, the appearance of the upper shell 400 can be optimized without affecting the function. For example, a streamlined or rounded corner treatment can be used to prevent workers from being scratched. At the same time, the upper shell 400 surface can be added with identification or indicator light to prompt the user to the correct wiring position or state information, improving the operation accuracy.

[0079] In some embodiments, in order to avoid safety hazards caused by incorrect connection, a unique shape or color mark can be set around each socket to form an intuitive anti-misplug guide system. In addition, a physical blocking structure can be integrated on the electrical connection plate 500, and only when the inserted object matches the shape can it smoothly enter the socket, otherwise it will be blocked outside. This way not only effectively prevents misoperation, but also significantly reduces training costs, especially for beginners.

[0080] With reference to Figures 1 to 3In some embodiments, the electrical connection part 200 of the auxiliary probe assembly 10 for single-phase electric energy meters also includes two slide rails 610. The two slide rails 610 are connected to the first arm 220 and the second arm 230 respectively and both extend along the first direction X. The design of the slide rails 610 enables the single-phase auxiliary probe assembly of the present application to be connected to other three-phase electric energy meter auxiliary probe assemblies in a sliding manner. Specifically, the slide rails 610 are linear guide rail structures that ensure good sliding performance and stability. In this way, users can conveniently install the auxiliary probe assembly 10 for single-phase electric energy meters on the auxiliary probe assembly of a three-phase electric energy meter for use, or detach it from the latter for on-site debugging and maintenance.

[0081] The presence of the slide rails 610 not only simplifies the installation process, improves work efficiency, but also enhances the flexibility of the system. Because the slide rails 610 provide stable guidance, the single-phase auxiliary probe assembly or the auxiliary probe assembly 20 of the three-phase electric energy meter will not deviate when being inserted or removed, ensuring the reliability and safety of the electrical connection. It can be understood that this design is also applicable to electric energy meters of different sizes and types, expanding the application range of the product.

[0082] In some embodiments, considering the stability requirements in actual use, mechanical locking devices such as spring clips or bolt fixings can be provided at the ends of the slide rails 610. When the auxiliary probe assembly is fully inserted into place, the locking device will automatically lock to prevent loosening due to vibration or other external forces. At the same time, when disassembly is required, it can be unlocked by simple operation, which is safe and convenient.

[0083] In some embodiments, considering that the slide rails 610 may be subject to wear and tear during long-term use, affecting the sliding performance. Therefore, high-strength, low-friction coefficient materials such as stainless steel, aluminum alloy or engineering plastics can be chosen to make the slide rails 610. These materials not only have excellent wear resistance characteristics, but also can effectively resist corrosion, prolonging the service life.

[0084] In some embodiments, in order to avoid damage caused by excessive insertion, physical limiting stops can be provided inside the slide rails 610. In this way, when the auxiliary probe assembly reaches the predetermined position, the limiting stops will prevent further advancement, ensuring accurate insertion each time. In addition, visual or tactile prompting functions can also be combined to remind users that they have reached the correct position, improving operation accuracy.

[0085] Reference Figures 1 to 3In some embodiments, in the auxiliary probe assembly 10 for single-phase electric energy meter, both slide rails 610 are arranged on the lower housing 600, and both slide rails 610 protrude from the upper housing 400 along the third direction Z. Such a design enables the slide rail 610 to not only provide a sliding connection function in the first direction X, but also form a stable support platform in the vertical direction (i.e., the third direction Z), and facilitate limiting the lateral movement of the probe 100.

[0086] Since the lower housing 600, the electric connection plate 500, and the upper housing 400 are sequentially arranged along the third direction Z, the lower housing 600 is located at the lowermost layer, by arranging the slide rail 610 on the lower housing 600 and protruding it along the third direction Z, the protruding height of the slide rail 610 can be set longer, and can support the side edges of the electric connection plate 500 and the upper housing 400, thereby enhancing the mechanical rigidity and vibration resistance of the entire assembly.

[0087] It can be understood that in some embodiments, the cross-sectional shape of the slide rail 610 can be optimized in consideration of special requirements in different application scenarios. For example, T-shaped, dovetail groove-shaped or other special-shaped structures can be used to adapt to more complex assembly environments. Such non-standard shapes not only provide better positioning accuracy, but also prevent accidental disengagement, increasing the safety of the connection.

[0088] In some embodiments, to further improve the installation efficiency, a quick installation interface such as a magnetic connector or a quick plug-in bayonet can be added between the slide rail 610 and the external device. This allows users to complete the installation and disassembly of the auxiliary probe assembly 20 for three-phase electric energy meter without tools, which is particularly suitable for situations where the test object is frequently replaced. In addition, the slide rail 610 can also integrate a foolproof design to ensure correct docking each time, prevent the end of the auxiliary probe assembly 20 for three-phase electric energy meter from being installed in reverse, and reduce the likelihood of misoperation.

[0089] The second aspect of the embodiments of the utility model provides a kind of detection device, including the auxiliary probe assembly 10 for single-phase electric energy meter of any one of the preceding embodiments, can save along the space of first direction, improve space utilization.

[0090] The above is only the preferred embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structural transformation made by using the utility model specification and drawing contents, or direct / indirect application in other related technical fields is included in the patent protection range of the utility model.
