Description

Technical Field

[0001] The present invention relates to the technical field of electricity meter calibration, and specifically relates to an error detection device for electricity meter measurement. Background Art

[0002] In the prior art, an electricity meter calibrator is an instrument used to calibrate the accuracy and error of an electricity meter. It can measure electrical parameters such as voltage, current, and power of a power supply grid, judge wiring errors, and achieve on-site calibration, data storage, and computerized management. It is widely used in industries such as electric power.

[0003] During the electricity meter calibration process, since an electricity meter usually has multiple detection points, multiple wires need to be used to connect to the calibrator. However, in the process of measuring and calibrating the error of an electricity meter by the existing electricity meter calibrator, the traditional calibration method often requires staff to manually connect each wire and the corresponding connector to the interface of the calibrator one by one. This process takes a long time and is prone to fatigue and negligence, thus affecting the accuracy and efficiency of calibration. And because staff need to operate the wires and connectors one by one, it is easy to cause the connector to fail to be correctly inserted into the interface or become loose and detached after insertion due to improper operation or negligence, thereby affecting the accuracy of the electricity meter measurement error detection and calibration data. In the traditional calibration method, the insertion process of the connector and the interface also lacks stability guarantee and is prone to looseness and detachment due to external force, which not only affects the accuracy of calibration but also damages the calibration equipment;

[0004] In addition, the interface of the existing electricity meter calibrator usually does not have a corresponding protective blocking structure, so that the interface is exposed to the external environment for a long time. When the interface is exposed to the external environment for a long time, it is very easy to accumulate impurities such as dust and sand grains. These impurities not only affect the appearance of the interface but also enter the inside of the interface, resulting in poor connection or connector damage when the connector is inserted later, thereby affecting the accuracy of calibration.

[0005] Therefore, in view of this, the present invention proposes an error detection device for electricity meter measurement to make up for and improve the deficiencies of the prior art. Summary of the Invention

A fixing seat is fixedly connected to the bottom of the open ring, and the fixing seats are respectively fixedly connected to the mounting frame and the bending plate. The electric wire is wound around the outer surface of the winding roller.

[0016] Preferably, the opening and closing control mechanism further includes a first connecting frame fixedly connected to the outer surface of the moving sleeve away from the linkage plate. The upper end of the first connecting frame is rotatably connected to the first connecting plate, and the other end of the first connecting plate away from the first connecting frame is rotatably connected to a second connecting frame.

[0019] Preferably, the end of the L-shaped driven plate away from the calibrator body is fixedly connected to an arc-shaped locking plate.

The arc-shaped locking plate is slidably connected to the bending plate, and the arc-shaped locking plate is used to lock the moving sleeve.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] (1) Through the setting of the centralized access mechanism, by using the elastic resetting effect of the elastic telescopic column on the push plate, the moving sleeve can be centrally pushed, so that the connector is inserted into the interface, thereby realizing the rapid and automatic plugging of the connector and the interface, enabling the connectors to be centrally accessed and uniformly managed, reducing manual intervention, eliminating the need for staff to operate the electric wires and connectors individually one by one, reducing errors caused by improper operation or negligence, and improving the accuracy of the calibration data for the metering error detection of the electric energy meter;

[0022] Among them, through the elastic resetting effect of the elastic telescopic column on the push plate, the push plate can tightly insert the connector into the interface, effectively preventing the connector from loosening and detaching due to external force during the mutual plugging process with the interface, thereby increasing the stability of the plugging between the connector and the interface, avoiding errors in the data results detected by the metering error detection of the electric energy meter, and further improving the accuracy of the detection data and reducing the probability of repeated calibration;

[0023] Among them, by using the snap - fit design of the mounting bracket and its top cover plate, when not in use, the top cover plate can cover the mounting bracket to form a relatively enclosed space between them, so as to store and protect each structure, avoiding the situation that dust, impurities and pollutants in the external air adhere to the surface of the structure along with the air flow. At the same time, it also reduces the contact with objects in the external environment when not in use, thereby improving the overall service life of the structure.

[0024] (2) Through the setting of the opening - closing control mechanism, during the process that the push - plate pushes the moving sleeve to drive the connector to move and plug into the interface, by using the linkage design of the first connecting plate, it can drive the sealing plate to slide upward on the side wall of the calibrator body to open the plugging of the interface, so that the interface is exposed, in order to enable the connector to be plugged into the interface. Thus, the function of synchronously driving and opening the sealing plate while the connector is plugged into the interface is realized. This design enables the staff not to operate the opening and closing of the sealing plate separately, and increases the compactness and linkage between structures, making the plugging and unplugging steps completed in one go, thereby simplifying the operation process and improving the operation efficiency.

[0025] Among them, positioning the end where the connector is located at the interface and cooperating with the design of automatic operation can reduce the operation difficulty during the calibration process, enabling non - professional personnel to easily complete the calibration work. Thus, it is not necessary to pre - match the connector and the interface during use, saving the preparation time for calibration and improving the calibration efficiency.

[0026] In addition, since the sealing plate initially covers the interface, it can plug the interface when not in use, avoiding external dust from entering the interior of the interface and affecting the subsequent insertion and use of the connector, thus ensuring the cleanliness of the interface and avoiding connection problems or connector damage caused by impurity pollution, and further ensuring the connection quality between the calibrator body and the electric energy meter.

[0027] (3) Through the setting of the locking control mechanism, when the interface is opened, by using the linkage effect of the second connecting plate and cooperating with the L - shaped driven plate to drive the two arc - shaped locking plates to move towards each other, the connector can be locked synchronously. This design can not only prevent the connector from loosening during the plugging and use process with the interface, ensure the signal transmission quality between the calibrator body and the electric energy meter, and ensure the accuracy of calibration data, but also reduce the risk of misoperation caused by improper manual operation through the locking of the connector by the arc - shaped locking plate, effectively ensuring the stable connection between the calibrator body and the electric energy meter. Therefore, it reduces the risk of equipment damage caused by poor connection, helps to improve the durability of the equipment, and reduces the maintenance cost caused by frequent replacement of damaged components.

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] Embodiment 1 of the present invention:

[0043] Please refer to Figures 1 to 8 As shown, an error detection device for electricity meter measurement includes a calibrator body 1, a wire 3, and a connector 4.

[0046] The locking control mechanism 7 includes a second connecting plate 702 and an arc-shaped locking plate 704. The arc-shaped locking plates 704 are symmetrically arranged on the outside of the moving sleeve 504. The second connecting plate 702 is arranged between the sealing plate 604 and the arc-shaped locking plate 704. The locking control mechanism 7 is used for synchronously locking the connector 4 while opening the interface 2;

[0047] The centralized access mechanism 5 further includes a mounting bracket 501 fixedly connected to the calibrator body 1. A top cover plate 502 is clamped on the top of the mounting bracket 501. Bent plates 503 are equidistantly and fixedly connected inside the mounting bracket 501. The moving sleeve 504 is slidably connected through the bent plates 503. Both the connector 4 and the wire 3 are fixedly arranged through the inner surface of the moving sleeve 504;

[0048] A fixing plate 505 is fixedly connected between the bent plate 503 and the mounting bracket 501. Elastic telescopic columns 506 are symmetrically and fixedly connected to the side of the fixing plate 505 facing the calibrator body 1. Chute 509s are opened on both the mounting bracket 501 and the bent plate 503. A push plate 507 is slidably connected through the chute 509s. The side of the push plate 507 facing the fixing plate 505 is fixedly connected to the elastic telescopic column 506;

[0049] One end of the movable sleeve 504 away from the calibrator body 1 is fixedly connected with a linkage plate 508, and the lower end of the linkage plate 508 is fixedly connected with one side of the push plate 507 facing the calibrator body 1;

[0050] On both sides of the mounting frame 501, fixing frames 510 are symmetrically and fixedly connected. A pressing plate 511 is rotatably connected to the fixing frames 510, and the pressing plate 511 is engaged with the mounting frame 501. One side lower end of the pressing plate 511 away from the calibrator body 1 is fixedly connected with an operating rod 512, and the pressing plate 511 is attached to one side of the push plate 507 facing the calibrator body 1;

[0051] A winding roller 515 is arranged between the mounting frame 501 and the bending plate 503. Both ends of the winding roller 515 are symmetrically and movably connected with open rings 514. The bottom of the open ring 514 is fixedly connected with a fixing seat 513, and the fixing seats 513 are respectively fixedly connected with the mounting frame 501 and the bending plate 503. The wire 3 is wound around the outer surface of the winding roller 515.

[0052] Please refer to Figures 1 to 2 , preferably: The calibrator body 1 and the mounting frame 501 are fixedly connected. A top cover plate 502 is clamped and arranged on the top of the mounting frame 501. When not in use, the top cover plate 502 covers the top of the mounting frame 501. When the top cover plate 502 and the mounting frame 501 are engaged with each other, a relatively airtight space can be formed inside. The arranged centralized access mechanism 5, opening and closing control mechanism 6 and locking control mechanism 7 are all accommodated in this space. Through the covering of the top cover plate 502, the structures and interfaces 2, wires 3 and connectors 4 included in these mechanisms can be protected, effectively avoiding the contact and adhesion of dust and other impurity pollutants in the external air with the air circulation. At the same time, through the protection formed by the combination of the top cover plate 502 and the mounting frame 501, it can also effectively avoid the situation that the structures in this space contact and collide with the objects in the external environment when the device is not in use, thereby improving the overall service life of the structure;

[0053] In addition, please refer to Figure 3 and Figure 4 , the wire 3 is wound around the outer surface of the winding roller 515. One end of the wire 3 is connected with a connector 4 adapted to the interface 2, and the other end of the wire 3 is connected with a plug adapted to the electric energy meter. Initially, this plug is suspended inside the mounting frame 501 through the winding of the wire 3, and the connector 4 is fixedly arranged on the inner surface of the movable sleeve 504, which can facilitate the subsequent control and drive of the connector 4 through the movable sleeve 504;

[0054] In addition, please refer to Figure 5, when the connector 4 and the interface 2 are not plugged together initially, the opposing surfaces of the abutting plate 511 and the pushing plate 507 are in abutting contact with each other, and at this time, the abutting plate 511 is clamped with the side wall of the mounting frame 501. Therefore, the position of the pushing plate 507 can be limited by the arrangement of the abutting plate 511. At this time, the elastic telescopic column 506 will be in a compressed state under the resistance of the abutting plate 511.

[0055] The effects achieved by this embodiment are as follows: Compared with the prior art, through the setting of the centralized access mechanism 5, by using the elastic resetting effect of the elastic telescopic column 506 on the pushing plate 507, the moving sleeve 504 can be centrally pushed, so that the connector 4 is inserted into the interface 2, thereby realizing the quick and automatic plugging of the connector 4 and the interface 2, enabling the centralized access and unified management of the connector 4, reducing manual intervention, eliminating the need for staff to operate the wire 3 and the connector 4 individually one by one, reducing errors caused by improper operation or negligence, and improving the accuracy of the data for detecting and calibrating the measurement error of the watt-hour meter;

[0056] Among them, through the elastic resetting effect of the elastic telescopic column 506 on the pushing plate 507, the pushing plate 507 can tightly insert the connector 4 into the interface 2, effectively preventing the connector 4 from loosening and detaching due to external force during the plugging process with the interface 2, thereby increasing the stability of the plugging between the connector 4 and the interface 2, avoiding errors in the data results detected and calibrated for the measurement error of the watt-hour meter, and further improving the accuracy of the detection data and reducing the probability of repeated calibration;

[0057] Among them, by using the clamping design of the mounting frame 501 and its top cover plate 502, when not in use, the cover plate 502 can cover the mounting frame 501 to form a relatively enclosed space therebetween, accommodating and protecting each structure, avoiding the situation where dust, impurities, and pollutants in the external air adhere to the surface of the structure as the air circulates, and at the same time reducing the contact with objects in the external environment when not in use, thereby increasing the overall service life of the structure.

[0058] Embodiment Two of the present invention:

[0059] Please refer to Figures 1 to 8 As shown, the opening and closing control mechanism 6 further includes a first connecting frame 601 fixedly connected to the outer surface of the end of the moving sleeve 504 away from the linkage plate 508. The upper end of the first connecting frame 601 is rotatably connected to the first connecting plate 602, and the end of the first connecting plate 602 away from the first connecting frame 601 is rotatably connected to a second connecting frame 603;

[0060] The second connecting frame 603 is fixedly connected to the upper end of the sealing plate 604. The sealing plate 604 is arranged between the interface 2 and the connector 4, and the sealing plate 604 is slidably connected to the calibrator body 1. The sealing plate 604 is used to block the interface 2.

[0061] Please refer toFigures 3 to 6 , more preferably: when the connector 4 and the interface 2 are not plugged in initially, the sealing plate 604 plugs the interface 2, which can prevent external dust from entering the interior of the interface 2 and affecting the subsequent insertion and use of the connector 4.

[0062] The effects achieved by this embodiment are as follows: Compared with the prior art, through the setting of the opening and closing control mechanism 6, during the process of the push plate 507 pushing the moving sleeve 504 to drive the connector 4 to move towards the interface 2 for plugging, by means of the linkage design of the first connecting plate 602, the sealing plate 604 can be driven to slide upward on the side wall of the calibrator body 1 to open the plugging of the interface 2, exposing the interface 2, so that the connector 4 can be plugged into the interface 2. Thus, the function of synchronously driving and opening the sealing plate 604 while the connector 4 is plugged into the interface 2 is realized. This design enables the staff to not need to operate the opening and closing of the sealing plate 604 separately, and increases the compactness and linkage between structures, making the plugging and unsealing steps smooth, thereby simplifying the operation process and improving the operation efficiency;

[0063] Among them, positioning the end where the connector 4 is located at the interface 2 and cooperating with the design of automated operation can reduce the operation difficulty during the calibration process, enabling non-professional personnel to easily complete the calibration work. Thus, it is not necessary to pre-match the connector 4 and the interface 2 during use, thereby saving the preparation time for calibration and improving the calibration efficiency;

[0064] In addition, since the sealing plate 604 initially covers the interface 2, it can plug the interface 2 when not in use, preventing external dust from entering the interior of the interface 2 and affecting the subsequent insertion and use of the connector 4, thereby ensuring the cleanliness of the interface 2 and avoiding connection problems or damage to the connector 4 caused by impurity contamination, and further ensuring the connection quality between the calibrator body 1 and the electric energy meter.

[0065] Embodiment III of the present invention:

[0066] Please refer to Figures 1 to 8 As shown, the locking control mechanism 7 further includes ear plates 701 symmetrically and fixedly connected to both sides of the upper end of the sealing plate 604. One end of the ear plate 701 away from the sealing plate 604 is rotatably connected to the second connecting plate 702, and one end of the second connecting plate 702 away from the ear plate 701 is rotatably connected to an L-shaped driven plate 703;

[0067] One end of the L-shaped driven plate 703 away from the calibrator body 1 is fixedly connected to an arc-shaped locking plate 704. The L-shaped driven plate 703 is slidably connected between the calibrator body 1 and the bending plate 503, and the arc-shaped locking plate 704 is slidably connected to the bending plate 503.

[0068] Please refer to Figures 1 to 8, preferably: two arc-shaped locking plates 704 are symmetrically arranged on both sides of the movable sleeve 504 with the movable sleeve 504 as the axis, and the arc-shaped locking plates 704 can be used to lock the movable sleeve 504.

[0069] The effects achieved by this embodiment are as follows: Compared with the prior art, through the setting of the locking control mechanism 7, while the interface 2 is opened, the linkage effect of the second connecting plate 702 can be utilized to drive the two arc-shaped locking plates 704 to move towards each other in cooperation with the L-shaped driven plate 703, and the connector 4 is locked synchronously. This design can not only prevent the connector 4 from loosening during the plugging and use process with the interface 2, ensure the signal transmission quality between the calibrator body 1 and the electric energy meter, and ensure the accuracy of the calibration data, but also reduce the risk of misoperation caused by improper manual operation through the locking of the connector 4 by the arc-shaped locking plate 704, effectively ensuring the stable connection between the calibrator body 1 and the electric energy meter. Therefore, the risk of equipment damage caused by poor connection is reduced, which helps to improve the durability of the equipment and reduces the maintenance cost caused by frequent replacement of damaged components.

[0070] The complete usage steps and working principle of the above embodiment are as follows:

[0071] In the initial state: As Figure 1 and Figure 2 shown, the calibrator body 1 is fixedly connected to the mounting bracket 501, and the top cover plate 502 is snap-fitted on the top of the mounting bracket 501. When not in use, the top cover plate 502 covers the top of the mounting bracket 501. When the top cover plate 502 and the mounting bracket 501 are snap-fitted with each other, a relatively closed space can be formed inside. The set centralized access mechanism 5, opening and closing control mechanism 6, and locking control mechanism 7 are all accommodated in this space. Through the covering of the top cover plate 502, the structures, interfaces 2, wires 3, and connectors 4 included in these mechanisms can be protected, effectively avoiding the contact and adhesion of dust and other impurity pollutants in the external air with the air flow. At the same time, through the protection formed by the combination of the top cover plate 502 and the mounting bracket 501, it can also effectively prevent the structures in this space from coming into contact and collision with the objects in the external environment when the equipment is not in use, thereby improving the overall service life of the structure. Moreover, through the centralized management method, the structures can be arranged and stored in an orderly manner, making the entire calibration equipment structure more compact, saving space, and facilitating carrying and transportation.

[0072] In addition, it should be noted that as Figure 3 and Figure 4As shown, the electric wire 3 is wound around the outer surface of the winding roller 515. One end of the electric wire 3 is connected with a connector 4 adapted to the interface 2, and the other end of the electric wire 3 is connected with a plug adapted to the electric energy meter. Initially, through the winding of the electric wire 3, this plug is suspended inside the mounting frame 501, while the connector 4 is fixedly arranged on the inner surface of the moving sleeve 504, which is convenient for subsequently controlling and driving the connector 4 through the moving sleeve 504;

[0073] It should also be noted that, as Figure 5 shown, when the connector 4 and the interface 2 are not plugged in initially, the facing surfaces of the abutting plate 511 and the pushing plate 507 are in contact with each other, and at this time, the abutting plate 511 is clamped with the side wall of the mounting frame 501. Therefore, through the setting of the abutting plate 511, the position of the pushing plate 507 can be limited. At this time, the elastic telescopic column 506 is in a compressed state under the blocking action of the abutting plate 511;

[0074] It should also be noted that, as Figure 3 、 Figure 4 and Figure 6 shown, when the connector 4 and the interface 2 are not plugged in initially, the sealing plate 604 plugs the interface 2, which can prevent external dust from entering the inside of the interface 2 and affecting the subsequent insertion and use of the connector 4, and the two arc-shaped locking plates 704 are symmetrically arranged on both sides of the moving sleeve 504 with the moving sleeve 504 as the axis.

[0075] The following is the working process of the centralized access mechanism 5 for centrally accessing the connector 4, and the opening and closing control mechanism 6 for simultaneously opening the plugging of the interface 2 while accessing the connector 4:

[0076] During use, as Figure 1 and Figure 2 shown, since the top cover plate 502 is clamped on the mounting frame 501, the staff can first remove the top cover plate 502 from the mounting frame 501, and then plug the plug connected to the end of the electric wire 3 away from the connector 4 into the electric energy meter to be detected and calibrated, while the connector 4 at the other end of the electric wire 3 is used to be plugged into the interface 2 opened on the calibrator body 1. Refer to Figure 3 、 Figure 4 and Figure 5As shown, since fixing brackets 510 are symmetrically and fixedly arranged on both sides of the mounting bracket 501, a resisting plate 511 is rotatably arranged on the fixing bracket 510, and the resisting plate 511 is initially clamped with the mounting bracket 501. A control rod 512 is fixedly arranged at the lower end of the resisting plate 511. The staff can drive the resisting plate 511 to rotate around the fixing bracket 510 by pushing the control rod 512. At this time, the clamping connection relationship between the resisting plate 511 and the mounting bracket 501 will be released. A push plate 507 is movably arranged through the mounting bracket 501, and the push plate 507 is slidably connected with the sliding groove 509. The opposite surfaces of the resisting plate 511 and the push plate 507 are in mutual abutment. During the rotation of the resisting plate 511, the abutting force exerted by the resisting plate 511 on the push plate 507 will gradually disappear, as Figure 3 shown. Also, since bending plates 503 are equidistantly and fixedly arranged on the mounting bracket 501, and a fixing plate 505 is fixedly arranged between the bending plate 503 and the mounting bracket 501, elastic telescopic columns 506 are symmetrically and fixedly arranged between the fixing plate 505 and the push plate 507. In the initial state, the elastic telescopic columns 506 are in a compressed state synchronously with the push plate 507 under the abutting action exerted by the resisting plate 511. When the resisting plate 511 releases the abutting action on the push plate 507, under the elastic action of the elastic telescopic columns 506, it will drive the push plate 507 to slide in the sliding groove 509 in a direction away from the fixing plate 505. Also, since a moving sleeve 504 is slidably arranged through the bending plate 503, and the moving sleeve 504 is fixedly connected with the joint 4, a linkage plate 508 is fixedly arranged on the outer surface of the end of the moving sleeve 504 away from the calibrator body 1, and the lower end of the linkage plate 508 is fixedly connected with the push plate 507. With the movement of the push plate 507, it will drive the linkage plate 508 to move synchronously towards the direction of the calibrator body 1. At this time, the moving sleeve 504 will also slide through the bending plate 503 synchronously towards the direction of the calibrator body 1. Since the moving sleeve 504 is fixedly connected with the joint 4, when the moving sleeve 504 moves, it will drive the joint 4 to move synchronously towards the direction of the calibrator body 1, as Figure 4 , Figure 7 and Figure 8As shown in the figure, a first connecting frame 601 is fixedly arranged on the outer surface of one end of the moving sleeve 504 away from the linkage plate 508. A second connecting frame 603 is fixedly arranged at the upper end of the sealing plate 604. A first connecting plate 602 is rotatably arranged between the second connecting frame 603 and the first connecting frame 601. Therefore, when the push plate 507 drives the moving sleeve 504 to penetrate and slide in the direction of the calibrator body 1 on the bending plate 503 through the linkage plate 508, the moving sleeve 504 will synchronously drive the first connecting frame 601 to move in the direction of the calibrator body 1. At this time, under the linkage action of the first connecting plate 602, the second connecting frame 603 can be driven to move upward, synchronously pulling the sealing plate 604 to slide upward on the outer wall of the calibrator body 1, exposing the interface 2 blocked by the sealing plate 604. When the sealing plate 604 moves upward, the joint 4 will be inserted into the interface 2 synchronously, realizing the insertion between the joint 4 and the interface 2. Among them, by pushing the operating rod 512, the abutting action of the abutting plate 511 on the push plate 507 is released. Then, by using the elastic reset action of the elastic telescopic column 506, the push plate 507 and the moving sleeve 504 are driven to move synchronously, realizing the automatic insertion of the joint 4 and the interface 2. This kind of automatic operation greatly reduces the human intervention and reduces the errors caused by improper operation or negligence, thus improving the accuracy of the detection data;

[0077] At the same time, since both the interface 2 and the joint 4 are provided in multiple numbers and the quantities correspond to each other, the number of the moving sleeves 504 provided is synchronously corresponding to the joint 4. And a single push plate 507 is provided, and the push plate 507 is fixedly connected to a plurality of moving sleeves 504 through the linkage plate 508. Therefore, when the abutting force of the push plate 507 is released, a plurality of moving sleeves 504 can be driven to penetrate the bending plate 503 and move in the direction of the calibrator body 1 synchronously, so that the joint 4 is pushed and inserted into the inside of the interface 2. When detecting and calibrating the error of the electric energy meter measurement and connecting multiple wires 3 and joints 4, the staff does not need to operate one by one separately, and can centrally complete the insertion task between the joint 4 and the interface 2. The operation is relatively convenient and simple, and the wires 3 and the joints 4 can be effectively stored when not in use, preventing the wires 3 and the joints 4 from being lost or soiled;

[0078] In this embodiment, through the elastic reset action of the elastic telescopic column 506 on the push plate 507, the push plate 507 can tightly insert the joint 4 into the interface 2, effectively preventing the joint 4 from loosening and detaching due to external force during the insertion process between the joint 4 and the interface 2, thereby increasing the stability of the insertion between the joint 4 and the interface 2, avoiding the error of the data result detected and calibrated for the electric energy meter measurement error, and further improving the accuracy of the detection data and reducing the probability of repeated calibration;

[0079] In the above process, through the setting of the centralized access mechanism 5, by the mutual cooperation among the moving sleeve 504, the push plate 507, the elastic telescopic column 506 and the abutting plate 511, the centralized access and unified management of the connector 4 are realized. This design enables the rapid completion of the plugging tasks of multiple connectors 4 with the interfaces 2 on the calibrator body 1 during the measurement error detection and calibration process of the watt-hour meter, without the need for staff to operate the wires 3 and connectors 4 individually one by one, greatly improving the work efficiency;

[0080] As Figure 4 and Figure 8 shown, since the sealing plate 604 initially covers the interface 2, it can block the interface 2 when not in use, preventing external dust from entering the interior of the interface 2 and affecting the subsequent insertion and use of the connector 4, ensuring the cleanliness of the interface 2 and avoiding connection problems or damage to the connector 4 caused by impurity contamination, thereby ensuring the connection quality between the calibrator body 1 and the watt-hour meter. Through the pushing setting of the push plate 507 on the moving sleeve 504, while driving the connector 4 to be plugged into the interface 2, the first connecting plate 602 can be used to synchronously drive and open the sealing plate 604 through its linkage effect, removing the coverage of the sealing plate 604 on the interface 2, thus achieving a quick response during use, enabling the connector 4 to be quickly inserted into the interface 2, reducing the risk of damage to the sealing plate 604 or contamination of the interface 2 caused by improper manual operation, effectively reducing the equipment maintenance cost, and helping to extend the service life of the calibrator body 1 and the watt-hour meter;

[0081] In this process, through the setting of the opening and closing control mechanism 6, by the pushing setting of the push plate 507 on the moving sleeve 504, the function of synchronously driving and opening the sealing plate 604 while the connector 4 is plugged into the interface 2 is realized. This design enables the staff to not need to operate the opening and closing of the sealing plate 604 separately, thus simplifying the operation process and improving the operation efficiency;

[0082] In addition, positioning the end where the connector 4 is located at the interface 2 and combining with the design of automated operation can reduce the operation difficulty during the calibration process, enabling non-professional personnel to easily complete the calibration work, thus eliminating the need to pre-match the connector 4 and the interface 2 during use, further saving the calibration preparation time and improving the calibration efficiency;

[0083] Please refer to Figures 1 to 8 for the above working process.

[0084] The following is the working process of the locking control mechanism 7 for locking the connector 4 synchronously while opening the interface 2:

[0085] In the previous text, during the process of pushing the moving sleeve 504 towards the direction of the calibrator body 1 through the push plate 507 and sliding it through the bending plate 503, so that the sealing plate 604 moves and opens, and the connector 4 is inserted into the interface 2, as Figure 6 and Figure 8 shown, since the ear plates 701 are symmetrically and fixedly arranged at the upper end of the sealing plate 604, the L-shaped driven plates 703 are symmetrically and slidably arranged between the calibrator body 1 and the bending plate 503, and the second connecting plate 702 is rotatably arranged between the L-shaped driven plate 703 and the ear plate 701. Therefore, as the sealing plate 604 moves upward, the ear plates 701 move upward synchronously. Under the linkage action of the second connecting plate 702, the two L-shaped driven plates 703 can be driven to move towards each other (i.e., move towards the center position of the connector 4), as Figure 6 shown, since the arc-shaped locking plates 704 are symmetrically arranged on both sides of the moving sleeve 504, and the side of the arc-shaped locking plate 704 away from the calibrator body 1 is slidably connected to the bending plate 503, and the arc-shaped locking plate 704 is fixedly connected to the L-shaped driven plate 703. Therefore, as the two L-shaped driven plates 703 move towards each other, the two arc-shaped locking plates 704 can be synchronously driven to slide on the bending plate 503 towards the outer surface direction of the moving sleeve 504, and finally, after the connector 4 and the interface 2 are inserted, the two arc-shaped locking plates 704 can closely fit on the outer surface of the moving sleeve 504 to lock and limit the position of the moving sleeve 504, avoiding the situation that the moving sleeve 504 slides on the bending plate 503 during the process of the calibrator body 1 detecting and calibrating the metering error of the external electric energy meter, thereby increasing the stability of the detection process and improving the data accuracy;

[0086] In the above process, through the setting of the locking control mechanism 7, while opening the interface 2, the linkage action of the second connecting plate 702 can be utilized to cooperate with the L-shaped driven plate 703 to drive the two arc-shaped locking plates 704 to move towards each other and lock the connector 4 synchronously. This design can not only prevent the connector 4 from loosening during the process of being inserted and used with the interface 2, ensure the signal transmission quality between the calibrator body 1 and the electric energy meter, thereby ensuring the accuracy of the calibration data, but also reduce the risk of misoperation caused by improper manual operation through the locking of the connector 4 by the arc-shaped locking plate 704, effectively ensuring the stable connection between the calibrator body 1 and the electric energy meter. Therefore, the risk of equipment damage caused by poor connection is reduced, which helps to improve the durability of the equipment and reduces the maintenance cost caused by frequent replacement of damaged components. In addition, through the linkage between various mechanisms, different from the cumbersome operation of separately performing the two independent steps of opening the interface 2 and limiting the connector 4, the operation efficiency can be greatly improved;
