Description

Technical Field

[0001] This application relates to the field of electricity meter calibration equipment technology, and in particular to a compatible wiring device, method of use and production line. Background Technology

[0002] Electricity meter calibration and testing is the most crucial step in electricity meter quality control. During testing, the meter is transported to a specific location via a parallel conveyor belt, where a wiring unit connects to the meter to power it on and performs various tests on its parameters. Currently, there are many types of electricity meters, each with different pin counts and pin spacing. Therefore, calibration production lines are custom-designed to fit these specifications and cannot be used for other types of meters. For example, a wiring unit for single-phase electricity meters can only test single-phase meters and cannot calibrate other types, such as three-phase meters or data acquisition terminals. This necessitates changing the calibration line when switching products. Therefore, a wiring unit compatible with multiple meters, which can adjust the current pin spacing and switch auxiliary pins to meet the calibration needs of various meters, is essential.

[0008] Multiple current needle kits are movably mounted on the mounting bracket;

[0009] A current needle switching module is used to drive the movement of each current needle assembly separately, so as to independently adjust the position of each current needle assembly;

[0027] The unlocking component is used to unlock the fixing component during the movement of the fixing mechanism from the second position to the first position, so that the auxiliary needle kit structure can move from the switching position to the bearing position, or from the bearing position to the switching position.

[0028] The unlocking component is also used to separate from the fixing component during the switching of the fixing mechanism from the first position to the second position, so that the fixing component can be reset to the fixed position.

[0032] The switching mechanism includes a lifting component and a push-pull component. The lifting component raises and lowers the temporary storage position so that one of the auxiliary needle assembly structures can dock with the push-pull component.

[0033] The push-pull component is used to push the auxiliary needle kit structure out of the temporary position and slide it through the switching position to reach the fixing mechanism.

[0034] Furthermore, each of the temporary storage positions is provided with a positioning post, which is used to limit and position the auxiliary needle assembly structure;

[0035] The fixing mechanism is provided with a fixing groove that mates with the temporary storage position;

[0036] The push-pull component is used to push the auxiliary needle assembly structure so that the auxiliary needle assembly structure is pushed out from the temporary position and, after passing the positioning post, is guided by the fixing groove to reach the fixing mechanism;

[0037] The push-pull component is also used to pull the auxiliary needle assembly structure to pull the auxiliary needle assembly structure out of the fixing mechanism and guided by the fixing groove, and after passing the positioning post, reach the temporary storage position.

[0038] As can be seen from the above technical solutions, the embodiments of this application have at least the following beneficial effects: by adjusting the position and spacing of each current needle assembly through the current needle switching module, and by cooperating with the switching mechanism and the power mechanism, the corresponding auxiliary needle assembly structure is brought to the crimping position, thereby enabling compatibility with the wiring detection and calibration requirements of various meters.

[0070] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0071] See Figures 1 to 12 As shown, an embodiment of the first aspect of this application discloses a compatible wiring device, including a mounting bracket 100, a current needle kit 200, a current needle switching module 300, an auxiliary needle kit structure 400, a switching mechanism 500, and a power mechanism 600.

[0072] Multiple current needle kits 200 are movably mounted on the mounting bracket 100; the current needle switching module 300 is used to drive each current needle kit 200 to move independently, so as to adjust the position of each current needle kit 200 independently; multiple auxiliary needle kit structures 400 are used in conjunction with different specifications of electricity meters, and each auxiliary needle kit structure 400 is movably mounted on the mounting bracket 100; the switching mechanism 500 is used to move one of the auxiliary needle kit structures 400 to the switching position; the power mechanism 600 is used to drive the auxiliary needle kit structure 400 located in the switching position to the crimping position, so that the auxiliary needle kit structure 400 can cooperate with the adjusted current needle kit 200 to calibrate the electricity meter of the preset specification.

[0073] In the embodiments of this application, the position and spacing of each current needle assembly 200 are adjusted by the current needle switching module 300, and the corresponding auxiliary needle assembly structure 400 is brought to the crimping position by the cooperation of the switching mechanism 500 and the power mechanism 600, thereby enabling compatibility with the wiring detection and calibration requirements of multiple meters. This application relates to the field of energy meter calibration equipment technology and is used to solve the technical defect in related technologies that a single meter wiring unit can only detect one type of meter.

[0074] It is understandable that the reason why wiring detection units in related technologies cannot be compatible with the verification of various marking specifications is mainly because the layout of the main current needle and auxiliary needle used for verification varies depending on the specifications of the energy meter, such as single-phase meters, three-phase meters, and data acquisition terminals. To address this technical problem of low compatibility in wiring detection units in related technologies, this application proposes a wiring device with adjustable current needle spacing and switchable auxiliary needles to meet the verification needs of various meters. More specifically, it enables compatible connection with single-phase meters, three-phase meters, and data acquisition terminals.

[0075] Specifically, the current needle switching module 300 independently drives the displacement of each current needle assembly 200, enabling independent adjustment of the position of the current needle assembly 200. This allows for precise adjustment of the spacing between adjacent current needle assemblies 200 according to the wiring requirements of different types of meters. Simultaneously, based on the specifications of the meter under test, a corresponding and suitable auxiliary needle assembly structure 400 is selected. The switching mechanism 500 powers the auxiliary needle assembly structure 400 to the switching position, and the power mechanism 600 then pushes the auxiliary needle assembly structure 400 to the crimping position. Through the coordination of the adjusted current needle assembly 200 with the corresponding auxiliary needle assembly structure 400, the testing and calibration of the corresponding specification of the energy meter is completed.

[0076] The above structure allows for the testing and calibration of various types of electricity meters without replacing the entire wiring device, greatly improving the equipment's universal compatibility. Furthermore, based on the current needle switching module 300, switching mechanism 500, and power mechanism 600, it ensures accurate and stable compatibility adjustment, enabling the electricity meter to automatically complete wiring contact and stable verification.

[0077] In some embodiments, the current needle switching module 300 has the function of grasping the current needle kit 200 and adjusting its movement. Specifically, the above function can be achieved by a combination of a multi-directional drive module and a grasping component, or by a mechanical arm in conjunction with the grasping component, or by a commonly used multi-degree-of-freedom drive structure such as a linkage mechanism in conjunction with the grasping component. In this regard, the specific structural design of the current needle switching module 300 is not further limited or described in detail, based on the ability to achieve the above functions.

[0078] Furthermore, in some embodiments, the switching mechanism 500 and the power mechanism 600 are used to drive the auxiliary needle kit structure 400 to move a preset stroke and reach a specific position at a specific location. This can be achieved through a combination of commonly used displacement mechanisms, conveying mechanisms, transfer mechanisms, and multi-degree-of-freedom displacement mechanisms. Similarly, based on the ability to achieve the above functions, the specific structural design of the switching mechanism 500 and the power mechanism 600 is not further limited or described.

[0079] In some embodiments, each auxiliary needle assembly structure 400 can adaptively adjust the layout of its auxiliary needles according to the actual testing requirements, so that it can still cooperate with multiple current needle assemblies 200 to complete the testing and calibration for different specifications of electricity meters.

[0080] It should be understood that, considering that the wiring device in this application embodiment needs to select the corresponding auxiliary pin assembly structure 400 according to the actual meter specifications, and move the corresponding auxiliary pin assembly structure 400 to the crimping position, at least one of the switching mechanism 500 and the power mechanism 600 should be configured to perform its movement switching function after the auxiliary pin assembly structure 400 in different positions has been moved. This can be achieved through station design, multi-degree-of-freedom displacement drive and control logic setting, which will not be further limited or described here.

[0081] The following will combine Figures 1 to 12 The compatible wiring device disclosed in the embodiments of this application will be explained and described in detail.

[0082] It should be understood that this is to make the current needle switching module 300 more integrated, its operation simpler, and its adjustment more precise.

[0083] In this regard, in some embodiments of this application, reference is made to Figures 1 to 5The current needle switching module 300 includes a first driving component 310, a second driving component 320, and a hook component 330. The current needle assembly 200 is provided with a locking component 210. The first driving component 310 is disposed on the second driving component 320. The first driving component 310 is used to drive the hook component 330 to move in a first direction, and the second driving component 320 is used to drive the hook component 330 to move in a second direction. When the hook component 330 moves in the first direction, it can reach a position that cooperates with the locking component 210 and lock or unlock the locking component 210. After unlocking the locking component 210, when the hook component 330 moves in the second direction, it can drive the current needle assembly 200 to move synchronously, thereby adjusting the position of the current needle assembly 200.

[0084] It is understandable that using the first drive component 310 and the second drive component 320 as power sources, along with the hook component 330, can automatically complete the unlocking and position adjustment of the current needle assembly 200. The first drive component 310 can drive the hook component 330 to move along a first direction, allowing it to reach the locking component 210 on the current needle assembly 200. It continues to move along the first direction to switch between locking and unlocking the locking component 210. After the locking component 210 is unlocked, the hook component 330 and the current needle assembly 200 work together. The second drive component 320 can drive the hook component 330 to move along a second direction, causing the entire current needle assembly 200 to move, completing the fine-tuning of the position and spacing of a single current needle assembly 200. By repeatedly adjusting one or more current needle assemblies 200 as needed, the position of the current needle assembly 200 can be stably locked after adjustment, thus adapting to the wiring hole positions of different energy meters and further improving the overall compatibility of the equipment and the accuracy and stability of the calibration operation.

[0085] In some embodiments, the first driving component 310 is an electric push rod, the second driving component 320 is a linear module, and the hook component 330 is specifically structured to be adapted to the locking component 210. The locking component 210 has a locked state and an unlocked state. The hook component 330 can switch the locking component 210 to the locked state by moving forward along the first direction, and can switch the locking component 210 to the unlocked state by moving backward along the first direction, thereby achieving the effect of fine-tuning the position and adjusting the spacing of the single set of current needle kits 200.

[0086] In one embodiment, reference is made to Figure 1 and Figure 2 The mounting bracket 100 includes a guide member 110, each current needle assembly 200 is slidably disposed on the guide member 110, a locking member 210 is movably disposed on the current needle assembly 200, and a hook member 330 is used to adjust the locking member 210 so that the locking member 210 can lock or release the guide member 110.

[0087] Understandably, the mounting bracket 100 is equipped with a guide component 110 to guide the sliding of the current needle assembly 200. All current needle assemblies 200 are mounted on the guide component 110 to achieve smooth sliding displacement. The hook component 330 and the locking component 210 work together. By adjusting the state of the locking component 210, the locking component 210 can clamp and fix the guide component 110 to complete the locking, or disengage from the guide component 110 to achieve release and unlocking. After unlocking, the current needle assembly 200 can slide freely along the guide component 110 to adjust its position, ensuring that the position of each set of current needle assemblies 200 is accurately adjusted and that the position is reliably fixed after adjustment.

[0088] In some embodiments, the guide component 110 includes at least three parallel guide rods, and each current needle assembly 200 is slidably disposed on each of the guide rods, thereby ensuring the accuracy of the sliding adjustment.

[0089] In one embodiment, reference is made to Figures 3 to 5 The current needle assembly 200 is provided with limiting parts 220 at intervals along the second direction. Each limiting part 220 is located on both sides of the locking member 210. After the hook member 330 unlocks the locking member 210, it moves and acts on the limiting parts 220 to drive the current needle assembly 200 to move synchronously.

[0090] Understandably, after the hook component 330 completes the unlocking operation of the locking component 210, it will move along the second direction and abut against the limiting part 220. By pushing or pulling the limiting part 220, the current needle assembly 200 will be driven to slide synchronously along the guide component 110, thereby completing the adjustment of the position and spacing of the current needle.

[0091] In some embodiments, the limiting part 220 is a plate-shaped component, which is respectively disposed on both sides of the locking part 210, so that after the hook part 330 moves along the first direction and acts on the hook part 330, it is located between the two limiting parts 220, and can abut against the limiting part 220 in either the forward or reverse direction of the second direction, thereby achieving the effect of driving the current needle assembly 200 to slide.

[0092] Understandably, in order to improve the docking accuracy of the power mechanism 600 and the switching mechanism 500, and to ensure the compatibility, automation and operational accuracy of the wiring device, a fixed mechanism 700 for connection can be set up to ensure precise docking between the power mechanism 600 and the switching mechanism 500.

[0093] In this regard, refer to Figures 1 to 2 , Figures 6 to 9In some embodiments of this application, a fixing mechanism 700 is provided on the power mechanism 600. The power mechanism 600 is used to drive the fixing mechanism 700 to move so that the fixing mechanism 700 switches between a first position and a second position. When the fixing mechanism 700 reaches the first position, it can receive and fix the auxiliary needle kit structure 400 from the switching position. When the fixing mechanism 700 reaches the second position, it can make the auxiliary needle kit structure 400 be in the crimping position.

[0094] Understandably, the power mechanism 600 outputs power to drive the fixing mechanism 700 to reciprocate, allowing the fixing mechanism 700 to switch between a first position and a second position. When the fixing mechanism 700 moves to the first position, it can receive and clamp the auxiliary needle assembly structure 400 delivered by the switching mechanism 500. When the fixing mechanism 700 moves to the second position, it carries the locked auxiliary needle assembly structure 400 to the crimping position, positioning the auxiliary needle assembly structure 400 in a position where it can dock with the energy meter. Through the limiting constraint of the fixing mechanism 700, the auxiliary needle assembly structure 400 will not deviate during movement, ensuring precise engagement with the meter when in the crimping position, reducing calibration errors and improving the degree of automation.

[0095] The fixing mechanism 700 needs to have two functions: fixing and releasing the auxiliary needle kit structure 400, so that the auxiliary needle kit structure 400 can switch between multiple positions. The fixing and releasing functions can be achieved by configuring an active power component, or by setting a passive or transmission power component.

[0096] In some specific embodiments, the fixing mechanism 700 includes a fixing frame 710, a fixing component 720, a spring component 730, and an unlocking component 740; the fixing frame 710 is provided with a bearing position 711 for supporting the auxiliary needle kit structure 400; the fixing component 720 is movably disposed on the fixing frame 710, and the fixing component 720 is used to fix the auxiliary needle kit structure 400 reaching the bearing position 711; the spring component 730 is used to provide an elastic force acting on the fixing component 720 so that the fixing component 720 can be maintained at or reset to the fixed position of fixing the auxiliary needle kit structure 400; the unlocking component 740 is used to unlock the fixing component 720 during the switching movement of the fixing mechanism 700 from the second position to the first position, so that the auxiliary needle kit structure 400 can move from the switching position to the bearing position 711, or from the bearing position 711 to the switching position; the unlocking component 740 is also used to separate from the fixing component 720 during the switching movement of the fixing mechanism 700 from the first position to the second position, so that the fixing component 720 can be reset to the fixed position.

[0097] Understandably, the support position 711 of the fixing bracket 710 is used to receive and place the auxiliary needle kit structure 400. The movable fixing part 720, relying on the elastic force of the elastic part 730, normally maintains a locked posture, which can continuously fix the auxiliary needle kit structure 400 in the support position 711. When the fixing mechanism 700 moves from the second position to the first position, the unlocking part 740 automatically contacts and pushes the fixing part 720, overcoming the elastic force to complete the unlocking, releasing the restraint on the auxiliary needle kit structure 400 or opening the support position 711, so that the auxiliary needle kit structure 400 can move into or out of the support position 711. When the fixing mechanism 700 moves from the first position to the second position, the unlocking part 740 gradually separates from the fixing part 720, the elastic part 730 releases the elastic force, and drives the fixing part 720 to automatically reset and lock, thereby reliably fixing the auxiliary needle kit structure 400 in the support position 711.

[0098] The above structure enables automatic unlocking and locking via the displacement of the mechanism, eliminating the need for independent drive components. This results in a simplified structure and a higher degree of automation. By linking and matching station switching with the locking and unlocking actions, smooth continuity of operation is ensured, improving the accuracy and efficiency of electricity meter calibration.

[0099] In some embodiments, the fixing component 720 may be a locking or limiting component, the elastic component 730 may be a spring or other structure that can provide elastic restoring force, and the unlocking component 740 may be a passive unlocking structure arranged along the path, or it may be an active unlocking structure configured to trigger an action when the fixing component 720 reaches a preset position. The appropriate method may be selected based on the actual situation.

[0100] In one embodiment, the unlocking component 740 includes a support rod that extends along the movement path of the fixing mechanism 700 and is located at a preset position that can cooperate with the fixing component 720. At least one of the support rod or the fixing component 720 is provided with a guide portion 750 so that when the support rod contacts the fixing component 720 during the movement of the fixing mechanism 700, the fixing component 720 can be moved away from the fixed position by the action of the guide portion 750.

[0101] Understandably, the support rod is arranged along the path of the overall reciprocating movement of the fixing mechanism 700, ensuring that it is in a fixed position that can contact the fixing component 720 on a certain section of the path; at least one of the support rod or the fixing component 720 has a guide portion 750 in the form of a bevel or chamfer. When the fixing mechanism 700 moves back to the first position, the fixing component 720 continuously approaches the support rod. After the two make contact, the beveled guide portion 750 pushes the fixing component 720 to shift, overcoming the elastic force of the elastic component 730 and leaving the locked fixed position, thus achieving automatic unlocking; when the fixing mechanism 700 moves forward to the second position, the fixing component 720 gradually disengages from the support rod, the guide portion 750 no longer applies a pushing force, and the fixing component 720 resets and locks under the action of the elastic force.

[0102] With the above structure, unlocking can be completed solely by the movement of the mechanism, and locking can be achieved by the spring force reset, without the need for additional power components. Moreover, the unlocking timing is completely matched with the movement of the workstation, thereby ensuring a smooth and stable pick-up, drop-off, and transfer process for the auxiliary needle kit structure 400, simplifying the overall machine transmission and control. The guide part 750 provides a smooth transition contact, ensuring a gentle unlocking action and reducing component wear.

[0103] In some embodiments of this application, reference is made to Figure 8 and Figure 9 The mounting bracket 100 is provided with a temporary storage mechanism 120, which has multiple temporary storage positions 121 spaced apart from each other. Each auxiliary needle kit structure 400 is slidably disposed on each temporary storage position 121 in a corresponding manner. The switching mechanism 500 includes a lifting component 510 and a push-pull component 520. The lifting component 510 lifts and lowers the temporary storage position 121 so that one of the auxiliary needle kit structures 400 can dock with the push-pull component 520. The push-pull component 520 is used to push the auxiliary needle kit structure 400 out of the temporary storage position 121 and slide it through the switching position to reach the fixing mechanism 700.

[0104] Understandably, different specifications of auxiliary needle kit structures 400 are slidably assembled on corresponding temporary storage positions 121, realizing the classified storage and standby of multiple models of auxiliary needle kit structures 400. During operation, the lifting component 510 raises and lowers the corresponding temporary storage position 121 according to the specifications of the meter under test, so that the target auxiliary needle kit structure 400 is aligned with the push-pull component 520 to complete the docking and positioning; then the push-pull component 520 extends to smoothly push the docked auxiliary needle kit structure 400 out of the temporary storage position 121, so that it slides along the preset trajectory through the switching position, and is finally sent into the fixing mechanism 700 to complete the loading.

[0105] The above structure enables the entire process of selection, pushing, and fixing to be completed automatically, eliminating the need for manual replacement of the auxiliary needle kit structure 400, shortening changeover time, and effectively improving the efficiency and stability of the calibration operation.

[0106] In some embodiments, each temporary storage position 121 is arranged vertically adjacent to each other so that each auxiliary needle kit structure 400 is arranged in a staggered layer, which not only facilitates the setting of the lifting component 510 and the push-pull component 520, but also facilitates cooperation with the fixing mechanism 700.

[0107] In some specific embodiments, each temporary storage position 121 is provided with a positioning post 122, which is used to limit and position the auxiliary needle assembly structure 400; the fixing mechanism 700 is provided with a fixing groove 760 that mates with the temporary storage position 121; the push-pull component 520 is used to push the auxiliary needle assembly structure 400 so that the auxiliary needle assembly structure 400 is pushed out of the temporary storage position 121 and, after passing through the positioning post 122, is guided by the fixing groove 760 to reach the fixing mechanism 700; the push-pull component 520 is also used to pull the auxiliary needle assembly structure 400 so that the auxiliary needle assembly structure 400 is pulled out of the fixing mechanism 700 and, guided by the fixing groove 760, passes through the positioning post 122 to reach the temporary storage position 121.

[0108] Understandably, when the auxiliary needle assembly structure 400 is stored in the temporary storage position 121, it relies on the positioning post 122 for limiting and positioning to ensure positional accuracy in standby mode. The fixing mechanism 700 has a fixing groove 760 that aligns with the temporary storage position 121, serving as a guide channel for the auxiliary needle assembly structure 400 to enter and exit. During operation, the push-pull component 520 pushes the auxiliary needle assembly structure 400 forward, causing it to detach from the temporary storage position 121 and slide out through the positioning post 122, then enter the fixing mechanism 700 through the guide of the fixing groove 760. After detection, the push-pull component 520 pulls the auxiliary needle assembly structure 400 in the opposite direction, causing it to retract along the fixing groove 760, be limited and guided again by the positioning post 122, and reset back to the corresponding temporary storage position 121, completing the entire retrieval and reset cycle.

[0109] Each temporary storage position 121 is independently spaced and does not interfere with each other. It is directly pushed and retrieved by the power mechanism 600, and the process is continuous and automated, thus enabling the verification and calibration of the electricity meter.

[0110] The second aspect of this application discloses a method for using a compatible wiring device. This method can be the same as the method for using a compatible wiring device as described in the first aspect of this application. The method for using a compatible wiring device includes the following steps:

[0111] Determine the specifications of the electricity meter to be tested;

[0112] According to the specifications of the electricity meter, the position of each current needle assembly 200 is independently adjusted by the current needle switching module 300.

[0113] According to the specifications of the electricity meter, the corresponding auxiliary needle assembly structure 400 is moved and switched to the switching position by the switching mechanism 500;

[0114] The auxiliary needle assembly structure 400 is moved to the crimping position by the power mechanism 600;

[0115] The electricity meter is calibrated by using the various current needle kits 200 and the auxiliary needle kit structure 400 together.

[0116] The following describes in detail, with a specific embodiment, the method of using a compatible wiring device according to the present application. It should be noted that the following embodiment is merely illustrative and should not be construed as limiting the scope of the present application.

[0117] It is understood that the compatible wiring device of this application embodiment can detect two single-phase meters, one three-phase meter, or one data acquisition terminal, etc., wherein the first driving component 310 adopts an electric push rod, the second driving component 320 adopts a left and right moving module, the hook component 330 includes a hook block, the locking component 210 adopts a locking hinge, the unlocking component 740 adopts a support rod, the fixing component 720 adopts a locking pin, the guide component 110 adopts a fixed shaft, the elastic component 730 adopts a spring, and the power mechanism 600 includes a lifting component 510 and a pushing and pulling component 520.

[0118] The specific implementation method is as follows:

[0119] 1.Reference Figure 10 Test two single-phase meters:

[0120] The electric actuator in the current needle switching module 300 drives the hook block forward, pushing the locking hinge to release the fixed shaft. The left-right moving module moves the hook block and the current needle assembly 200 left and right to adjust. After reaching the correct position, the electric actuator drives the hook block backward. When the hook block moves backward, it pulls the locking hinge to fix the current needle assembly 200 onto the shaft. The above process is repeated to move each of the eight current needle assemblies 200 to the single-phase current needle position and fix them.

[0121] The power mechanism 600 drives the fixing mechanism 700 to slide to the first position. During this process, the support rod pushes the locking pin to open. The lifting component 510 drives the auxiliary needle kit structure 400 for single-phase meters to rise and fall and align with the fixing mechanism 700. The push-pull component 520 pushes the single-phase auxiliary needle kit structure 400 for single-phase meters into the fixing mechanism 700 and then fixes it in the fixing groove 760 on the fixing mechanism 700 after passing through the positioning post 122.

[0122] The power mechanism 600 drives the fixing mechanism 700 to slide to the second position, the support rod disengages from the locking pin, the locking pin is pushed out by the spring, and the single-phase auxiliary needle kit structure 400 is fixed to the fixing mechanism 700 by the locking pin. When the single-phase auxiliary needle kit and the current needle kit 200 are in place, the two single-phase meters can be transferred over for testing.

[0123] 2.Reference Figure 11 Testing a three-phase meter:

[0124] In the current needle switching module 300, the electric actuator drives the hook block forward, pushing the locking hinge to release the fixed shaft. The left-right moving module moves the hook block and the current needle assembly 200 left and right to adjust. After reaching the correct position, the electric actuator drives the hook block backward. When the hook block moves backward, it pulls the locking hinge to fix the current needle assembly 200 onto the shaft. The above process is repeated to move each of the eight current needle assemblies 200 to the corresponding position of the three-phase current needle and fix them.

[0125] The power mechanism 600 drives the fixing mechanism 700 to slide to the first position. During this process, the support rod pushes the locking pin to open. The lifting component 510 drives the auxiliary needle kit structure 400 for the three-phase current needle to rise and fall and align with the fixing mechanism 700. The push-pull component 520 pushes the single-phase auxiliary needle kit structure 400 for the three-phase current needle into the fixing mechanism 700 and then fixes it in the fixing groove 760 on the fixing mechanism 700 after passing through the positioning post 122.

[0126] The power mechanism 600 drives the fixing mechanism 700 to slide to the second position, the support rod disengages from the locking pin, the locking pin is pushed out by the spring, and the single-phase auxiliary needle kit structure 400 is fixed to the fixing mechanism 700 by the locking pin. When the single-phase auxiliary needle kit and the current needle kit 200 are in place, the two single-phase meters can be transferred over for testing.

[0127] 3.Reference Figure 12 Testing a data acquisition terminal:

[0128] In the current needle switching module 300, the electric actuator drives the hook block forward, pushing the locking hinge to loosen the fixed shaft. The left-right moving module moves the hook block and the current needle assembly 200 left and right to adjust. After reaching the correct position, the electric actuator drives the hook block backward. When the hook block moves backward, it pulls the locking hinge to fix the current needle assembly 200 onto the shaft. The above process is repeated to move each of the eight current needle assemblies 200 to the current needle position of the acquisition terminal and fix them in place.

[0129] The power mechanism 600 drives the fixing mechanism 700 to slide to the first position. During this process, the support rod pushes the locking pin to open. The lifting component 510 drives the auxiliary needle kit structure 400 for the acquisition terminal to rise and fall and align with the fixing mechanism 700. The push-pull component 520 pushes the single-phase auxiliary needle kit structure 400 for the acquisition terminal into the fixing mechanism 700 and fixes it in the fixing groove 760 on the fixing mechanism 700 after passing through the positioning post 122.

[0130] The power mechanism 600 drives the fixing mechanism 700 to slide to the second position, the support rod disengages from the locking pin, the locking pin is pushed out by the spring, and the single-phase auxiliary needle kit structure 400 is fixed to the fixing mechanism 700 by the locking pin. When the single-phase auxiliary needle kit and the current needle kit 200 are in place, the two single-phase meters can be transferred over for testing.
