Description

Technical Field

[0001] This utility model relates to the field of power meter technology, and in particular to a panel meter calibration fixture. Background Technology

[0002] Panel meters (AC panel smart meters), as one type of smart power meter, are multifunctional power meters designed specifically for power monitoring, intelligent control, and metering assessment in scenarios such as power systems, industrial and mining enterprises, public facilities, and smart buildings, occupying a core position in power monitoring systems. As an energy metering instrument, calibration and verification of metering errors are crucial steps in ensuring the performance and accuracy of panel meters during the manufacturing process. The primary prerequisite for accurate metering accuracy verification is ensuring a reliable connection between the panel meter under test and the calibration equipment.

[0003] However, the industry currently faces a practical problem: the interfaces on panel meters use a multi-set Phoenix terminal block design, but commonly used calibration equipment is mainly designed for State Grid single-phase or three-phase meters, lacking dedicated equipment for direct calibration of panel meters. Therefore, in actual testing, it is necessary to use self-made cables and manually plug and unplug the panels one by one to connect them to the calibration platform. Specifically, the existing connection method between the panel meter and the calibration platform is usually achieved using a self-made test adapter cable. This adapter cable is an integration of multiple functional wire harnesses; one end is equipped with multiple multi-core pluggable Phoenix plugs for connecting to the Phoenix socket interface of the panel meter; the other end connects to the calibration equipment to complete the connection of phase voltage terminals, phase current terminals, multi-function detection terminals, and 485 communication terminals. Afterwards, the panel meter barcode is manually scanned and entered sequentially before calibration can begin. It is worth noting that the plugs that connect to the Phoenix socket on the panel meter all have an anti-dislodgement design. When operating by hand, you need to gradually insert and tighten them to ensure a tight contact at the interface until the anti-dislodgement buckle on the plug locks the socket. This ensures good contact during the calibration and verification of the panel meter's measurement error. When disassembling, you need to press down on the plug's locking buckle while gently shaking it, and slowly pull the plug out.

[0004] However, this operating method has revealed many drawbacks during mass production: First, the operation is extremely time-consuming and labor-intensive, requiring operators to invest a significant amount of time and energy to complete the process, resulting in low production efficiency. Second, during batch production inspection, each panel requires multiple external wiring harnesses, leading to a disorganized production site, easy mis-insertion of connectors, and increased operational difficulty and quality control costs. Third, due to the repetitive and monotonous nature of the operation, operators find it difficult to maintain high concentration for extended periods, increasing the risk of misaligned or deformed connector pins.

[0005] In summary, to solve the connection problems existing in the current panel meter calibration process, improve production efficiency, and reduce quality risks, it is particularly necessary to design a special panel meter calibration fixture. Utility Model Content

[0006] This utility model provides a panel meter calibration fixture to solve the problems of low production efficiency, difficult on-site operation, high quality control management costs, and easy quality risks caused by the use of self-made test adapter cables in the calibration process of existing panel meters.

[0007] This utility model provides a panel dial gauge calibration fixture, comprising:

[0008] The body has at least one test position on one side surface, which is used to support the panel.

[0009] The plugging and unplugging mechanism is set on the machine body and is set one by one with the test positions. It includes a plug assembly and a cylinder boosting mechanism. The cylinder boosting mechanism is fixed on the machine body and the plug assembly is fixed on the cylinder boosting mechanism.

[0010] The plug assembly includes a Phoenix plug adapted to the Phoenix socket of the panel watch, and the panel watch is connected to the calibration fixture via the Phoenix plug; the cylinder booster mechanism includes a moving end, which is used to move in a direction perpendicular to the panel watch to push the panel watch to move away from the machine body, thereby disengaging the Phoenix socket from the Phoenix plug.

[0011] Optionally, the cylinder booster mechanism includes a cylinder fixing bracket and a cylinder. The cylinder fixing bracket is a hollow frame structure, and the cylinder is fixed in the middle of the cylinder fixing bracket. The cylinder includes the moving end.

[0012] When the Phoenix socket and the Phoenix plug are connected, the moving end is housed within the cylinder fixing bracket; when the Phoenix socket and the Phoenix plug are disengaged, the moving end extends out of the cylinder fixing bracket to push the panel to move away from the body.

[0013] Optionally, the plug assembly is fixed to the side of the cylinder mounting bracket facing the panel, and the plug assembly is located on opposite sides of the cylinder.

[0014] Optionally, the plug assembly further includes a plug fixing block, through which the Phoenix plug is fixed to the cylinder fixing bracket.

[0015] Optionally, the cylinder booster mechanism further includes a buffer pad, which is disposed on the moving end, and the moving end contacts the panel surface through the buffer pad.

[0016] Optionally, the fuselage has a plurality of test positions along its length, with adjacent test positions spaced apart from each other.

[0017] Optionally, the calibration fixture also includes a barcode scanning component, which is set on one side of each test position to scan the barcode affixed to the panel to obtain the barcode information of the panel.

[0018] Optionally, the scanning component includes a barcode scanner holder and a barcode scanner. The barcode scanner is fixed to the machine body via the barcode scanner holder, and the barcode scanner is positioned at the barcode location on the panel.

[0019] Optionally, the calibration fixture also includes a control switch, which is disposed on the machine body and includes a fixture power switch and control function buttons.

[0021] The above-mentioned technical solution of this utility model has the following beneficial effects:

[0022] This utility model discloses a panel meter calibration fixture. By incorporating a plug-in mechanism on the fixture body, a phoenix plug on the mechanism connects to the phoenix socket of the panel meter. A cylinder-assisted mechanism on the plug-in mechanism pushes the panel meter away from the machine body, achieving rapid disengagement of the phoenix socket and plug. This saves time and effort, improving work efficiency. Furthermore, the vertical push of the cylinder-assisted mechanism avoids the quality risks associated with manual shaking during plug removal. The fixture's overall structure is simple and practical, preventing messy wiring on the production floor and solving the problem of lacking dedicated calibration equipment for panel meters. It makes reasonable use of existing calibration equipment to meet the production needs of panel meters, eliminating the need for expensive custom-made equipment and saving manufacturing costs.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] Please see Figure 1 and Figure 3 This utility model provides a panel meter calibration fixture, including a machine body 1 and a plug-in mechanism 2. The upper surface of the machine body 1 is provided with at least one test position 100, which is used to support the panel meter. The plug-in mechanism 2 is disposed on the machine body 1 and is arranged one-to-one with the test positions 100. The plug-in mechanism 2 includes a plug assembly 20 and a cylinder booster mechanism 21. The cylinder booster mechanism 21 is fixed on the machine body 1, and the plug assembly 20 is fixed on the cylinder booster mechanism 21.

[0032] The plug assembly 20 includes a Phoenix plug 200 adapted to the Phoenix socket of the panel meter, and the panel meter is connected to the calibration fixture via the Phoenix plug 200. The cylinder booster mechanism 21 includes a moving end, which is used to move in a direction perpendicular to the panel meter to push the panel meter away from the machine body 1, thereby disengaging the Phoenix socket from the Phoenix plug 200.

[0033] This utility model's calibration fixture, through the inclusion of a plug assembly 20 adapted to the Phoenix socket of the panel meter, allows for direct plug-in connection between the Phoenix socket of the panel meter and the Phoenix plug 200 of the fixture. This eliminates the need for self-made wiring, avoiding messy wiring on the production floor, effectively mitigating the risk of plug misalignment, and ensuring operational safety. Furthermore, a cylinder-assisted mechanism vertically pushes the panel meter to release the connector, avoiding the quality risks associated with manual shaking and unplugging. This rapid release method saves time and effort, improving work efficiency. The fixture's overall structure is simple and practical, meeting the production needs of panel meters without requiring expensive dedicated calibration equipment, thus saving manufacturing costs.

[0034] Specifically, see Figure 1 and Figure 2 The machine body 1 has a hollow shell structure, and the insertion / removal mechanism 2 can be set inside the machine body 1. The upper surface of the machine body 1 has an opening 101 corresponding to each test position 100 to expose the insertion / removal mechanism 2. The machine body 1 includes a main support 10 and a handle 11. The handle 11 is rotatably set on opposite sides of the main support 10 to facilitate the overall movement of the tooling. When stationary, it can be folded to save space.

[0035] Furthermore, the machine body 1 is provided with multiple test positions 100 along its length, with adjacent test positions 100 spaced apart from each other, which can meet the requirement of multiple panel meters to perform calibration operations at the same time, thereby improving production efficiency.

[0036] See Figure 3 The cylinder-assisted mechanism 21 includes a cylinder mounting bracket 210 and a cylinder 211. The cylinder mounting bracket 210 is a hollow frame structure, fixed to the inner bottom surface of the machine body 1 corresponding to the opening 101. The cylinder 211 is fixed to the middle of the cylinder mounting bracket 210, and includes a moving end for moving along a direction perpendicular to the bottom surface or panel of the machine body 1. The plug assembly 20 is fixed to the side of the cylinder mounting bracket 210 facing the panel, and is located on opposite sides of the cylinder 211. The plug assembly 20 includes a phoenix plug 200 and a plug fixing block 201. The phoenix plug 200 is fixed to the cylinder mounting bracket 210 by the plug fixing block 201, and high-voltage and low-voltage signals are connected to the phoenix plug 200 of the tooling through external power supply and communication terminals.

[0037] With the Phoenix socket and Phoenix plug 200 connected, the moving end of the cylinder 211 is housed within the cylinder mounting bracket 210, providing clearance for the connection between the panel dial and the calibration fixture. When the Phoenix socket and Phoenix plug 200 are disengaged, the moving end of the cylinder 211 extends out of the cylinder mounting bracket 210 to push the panel dial away from the machine body 1, thereby achieving rapid disengagement of the Phoenix socket and Phoenix plug 200.

[0038] Furthermore, the cylinder booster mechanism 21 also includes a buffer pad 212, which is disposed on the moving end of the cylinder 211. The moving end of the cylinder 211 contacts the panel watch through the buffer pad 212, which can prevent the cylinder 211 from scratching the surface of the panel watch housing when it moves.

[0039] See Figure 1 , Figure 3 and Figure 4 The calibration fixture also includes a barcode scanning component 3, which is positioned one-to-one on one side of the test position 100. This component scans the barcodes affixed to the panel display to obtain the barcode information. Specifically, the barcode scanning component 3 includes a barcode scanner holder 30 and a barcode scanner 31. The barcode scanner 31 is fixed to the machine body 1 via the barcode scanner holder 30 and is positioned at the corresponding barcode location on the panel display to scan the barcodes affixed to the panel display and obtain the barcode information.

[0040] See Figure 1 and Figure 2 Furthermore, the calibration fixture also includes a control switch 4, which is mounted on the machine body 1. The control switch 4 includes a fixture power switch 40, control function buttons 41, and reserved function buttons 42. The fixture power switch 40 is used to power on or off the cylinder booster mechanism 21, the control function buttons 41 are used to control the movement state of the cylinder booster mechanism 21, and the reserved function buttons 42 can be reserved for other functions of the fixture according to actual needs.

[0041] Furthermore, the body 1 is also equipped with multiple ports 5, which are used to connect to external power supply equipment, external air supply equipment and external communication equipment respectively.

[0042] It should be noted that, in addition to the structure shown above, the calibration fixture still needs to connect standard equipment (such as calibration table, computer and calibration software, connecting harness, etc.) and air source equipment (such as air compressor, etc.) to the fixture circuit shown above according to the testing requirements.

[0043] In addition, this calibration fixture is not limited to calibration processes; it can also be applied to other power-on communication testing processes for panel meters, making it highly versatile and efficient.

[0044] The operation process of the calibration fixture of this utility model is as follows:

[0045] 1. Connect the meter calibration fixture to the current and voltage interfaces, multi-function communication terminals, and gas source equipment of the meter calibration equipment;

[0046] 2. Place the panel face up in the corresponding test position of the fixture, and manually and steadily press down to ensure good contact between the Phoenix socket of the panel and the Phoenix plug built into the fixture.

[0047] 3. After starting and completing the calibration process for the panel meter, disconnect the voltage and current source from the calibration platform to the tooling output.

[0048] 4. Press the control switch to trigger the cylinder to push, causing the Phoenix socket on the panel meter to disengage from the Phoenix plug on the tooling. Remove the panel meter, take out the defective product, and complete the meter calibration process.

[0049] This utility model's calibration fixture is designed based on the characteristics of panel meter interfaces. Panel meter testing requires numerous connecting wires to its ports. By connecting the external calibration platform to the Phoenix plugs inside the fixture via its ports, it ensures stable and reliable connections during testing and maintains a neat production site. The fixed Phoenix plugs inside the fixture eliminate the need for manual connection, avoiding the risk of incorrect insertion. The fixture's overall structure is simple and its manufacturing cost is low.

[0050] When removing the panel meter, the cylinder is controlled by lightly touching the function button, causing the cylinder to push the bottom of the panel meter housing upward at a constant speed, disengaging the Phoenix plug from the Phoenix socket. After the panel meter is pushed out of the fixture body, the panel meter part is exposed in the fixture body, and the operator can easily remove the panel meter, avoiding the quality risks caused by manually shaking and pulling out the plug.

[0051] During testing, the barcode scanning and input operation on the side of the panel can be automatically completed by linking with host computer software such as calibration software, avoiding the risk of scanning the wrong barcode during manual operation.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
