Description

Technical Field

[0001] This application relates to the field of testing tooling technology, specifically a testing tooling for the communication interface of an electricity meter. Background Technology

[0002] An electricity meter is an instrument used to measure electrical energy. The accuracy of electricity meter measurement is directly related to the interests of both electricity suppliers and users, and directly affects social stability and development. Therefore, before packing the electricity meter, in order to prevent individual parts of the internal circuit of the electricity meter from malfunctioning, it is necessary to test the reliability of the electricity meter.

[0003] The existing electricity meter communication interface testing fixture is a professional testing device used to verify the function, performance and reliability of the electricity meter communication interface. Its role runs through the entire process of electricity meter research and development, production and operation and maintenance. However, once the existing device fails, it requires professional personnel to repair it. Moreover, if the communication protocol is updated, the fixture may not be able to be upgraded and needs to be purchased again. In addition, the existing device has a complex structure and irregular shape, making it inconvenient to carry to the field for testing.

[0004] Therefore, a new approach is needed to solve this problem. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a testing fixture for the communication interface of an electricity meter, which has advantages such as the ability to quickly adjust the testing angle and solves the problem of inconvenience in carrying existing technologies.

[0006] To achieve the above objectives, this application provides the following technical solution: a testing fixture for a communication interface of an electricity meter, comprising a fixed frame, an internal support plate, connecting blocks fixedly connected to both sides of the support plate, the outer surfaces of the connecting blocks being rotatably connected to the fixed frame, two support columns rotatably connected to the bottom surface of the support plate, two fixing grooves formed on the inner wall of the fixed frame, the outer surface of each support column engaging with the corresponding fixing groove, a plurality of mounting holes evenly formed on the upper surface of the support plate, an interface testing module fixedly mounted on the upper surface of the support plate, and two slots formed on the outer surface of the fixed frame.

[0007] Through the above scheme, the test fixture uses a fixed frame as the overall framework. It not only provides the installation foundation for other components, but also protects the internal components and maintains the stability of the overall structure. The support plate provides a support foundation for the test fixture, and the setting of the connecting block allows the support plate to rotate flexibly within a certain angle range, which greatly facilitates subsequent testing operations. The support column adopts a telescopic design, and its material has good wear resistance and pressure resistance. When it is necessary to adjust the angle of the support plate, the support column can be pulled out from the fixed groove, the support plate can be rotated to the appropriate angle, and then the support column can be inserted into the fixed groove to achieve quick fixation of the angle of the support plate. The mounting holes are designed strictly according to standard dimensions, which can be adapted to various specifications of electricity meter communication interface testing equipment, making it convenient for staff to quickly install and replace testing equipment according to actual testing needs. The slot adopts a dovetail groove structure design, and its interior is equipped with anti-slip rubber pads, which can fit tightly with the external fixing device to ensure that the test fixture is stable and does not shake during use.

[0008] Furthermore, the upper surface of the support plate is slidably connected to the electricity meter body, and the outer surface of the electricity meter body is provided with an infrared detection module.

[0009] The above-mentioned solution utilizes an infrared detection module. This module employs a non-contact detection principle and incorporates a high-precision infrared sensor array. It can monitor parameters such as temperature and infrared radiation intensity of the electricity meter's communication interface in real time. During testing, the infrared detection module can quickly capture minute temperature changes on the interface surface and analyze and determine whether there are potential faults such as poor contact or overheating through built-in algorithms.

[0010] Furthermore, a communication test module is provided on the outer surface of the electricity meter body, and the output end of the interface test module is plugged into the communication test module.

[0011] The above scheme allows for a plug-in quick connection between the communication test module and the interface test module. The output end of the interface test module is equipped with a high-precision pin-type interface, and the corresponding position of the communication test module is equipped with a matching slot. After the two are plugged in, a stable electrical connection can be formed. This design not only makes it easy for staff to quickly replace communication test modules with different functions to meet diverse testing needs, but also ensures the stability and accuracy of data during transmission.

[0012] Furthermore, a screw is rotatably connected to the inner wall of the support plate, and an extrusion plate is threadedly connected to the outer surface of the screw. The outer surface of the extrusion plate is slidably connected to the support plate, and a rotating wheel is fixedly connected to the end of the screw away from the support plate.

[0013] With the above method, when it is necessary to fix the electricity meter body, the staff only needs to hold the rotating wheel and rotate it clockwise. The screw will rotate accordingly, driving the pressing plate to move towards the electricity meter body along the axial direction of the screw until the pressing plate fixes the electricity meter body.

[0014] Furthermore, a slot is provided on the outer surface of the support plate, and a connecting plate is rotatably connected to the inner wall of the slot. An infrared detector is fixedly installed on the outer surface of the connecting plate.

[0015] Through the above solution, the connecting plate is connected to the inner wall of the slot by a rotating shaft and a miniature bearing. This design allows the connecting plate to rotate freely, and the staff can easily adjust the detection angle of the infrared detector according to the actual testing needs, ensuring that all parts of the electricity meter body can be tested in an all-round way.

[0016] Furthermore, the inner wall of the support plate is slidably connected to two connecting rods, each connecting rod having a locking block fixedly connected to the end away from the support plate, and each connecting rod having a slider fixedly connected to the end near the support plate.

[0017] With the above solution, by pulling the locking block, the locking block will drive the corresponding connecting rod to slide horizontally along the support plate. At this time, the connecting rod will drive the corresponding slider to slide horizontally along the support plate.

[0018] Furthermore, each of the connecting rods has a spring fitted onto its outer surface. The ends of the two springs that are close to each other are fixedly connected to the corresponding sliders, and the other ends are fixedly connected to the support plate.

[0019] With the above method, the spring will be compressed during the pulling of the connecting rod. When no external force is applied, the spring will push the corresponding slider to reset under the action of its rebound force.

[0020] Furthermore, each of the two card blocks has a pull block fixedly connected to one end of each block that is far apart from the other, and the outer surface of each card block engages with the corresponding card slot.

[0021] With the above solution, when the card block is pulled and fully inserted into the slot, the elastic rubber strip will press tightly against the card block, generating additional friction to prevent the card block from accidentally coming out during the test, thus enhancing the stability of the electricity meter.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This is a testing fixture for the communication interface of an electricity meter. An adjustable support plate allows for angle adjustment during use, facilitating user observation of test results. Pulling a lever moves a corresponding locking block horizontally until it engages with its corresponding slot, thus quickly securing the support plate. Opening and closing the support plate allows for neat and organized storage during use, facilitating transportation and reducing external damage. Attached Figure Description

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.

[0032] Please see Figure 1 , Figure 2 and Figure 3This embodiment of a test fixture for a communication interface of an energy meter includes a fixed frame 1. The fixed frame 1 has a support plate 4 inside. Connecting blocks 6 are fixedly connected to both the left and right sides of the support plate 4. The outer surface of the connecting blocks 6 is rotatably connected to the fixed frame 1. Two support columns 22 are rotatably connected to the bottom surface of the support plate 4. Two fixing grooves 2 are opened on the inner wall of the fixed frame 1. The outer surface of each support column 22 is engaged with the corresponding fixing groove 2. Several mounting holes 5 are evenly opened on the upper surface of the support plate 4. An interface test module 7 is fixedly installed on the upper surface of the support plate 4. Two slots 3 are opened on the outer surface of the fixed frame 1.

[0033] Please see Figure 1 and Figure 3 The upper surface of the support plate 4 is slidably connected to the energy meter body 11. The outer surface of the energy meter body 11 is provided with an infrared detection module 8. The infrared detection module 8 adopts a non-contact detection principle and has a built-in high-precision infrared sensor array. It can monitor parameters such as the temperature and infrared radiation intensity of the energy meter communication interface in real time. During the test, the infrared detection module 8 can quickly capture the subtle temperature changes on the interface surface and analyze and judge whether there are potential faults such as poor contact or overload heating through the built-in algorithm.

[0034] Please see Figure 3 The outer surface of the electricity meter body 11 is provided with a communication test module 9. The output end of the interface test module 7 is plugged into the communication test module 9. The communication test module 9 and the interface test module 7 adopt a plug-in quick connection method. The output end of the interface test module 7 is provided with a high-precision pin interface, and the corresponding position of the communication test module 9 is equipped with a matching slot. After the two are plugged in, a stable electrical connection can be formed. This design not only makes it easy for staff to quickly replace the communication test modules 9 with different functions to meet diverse testing needs, but also ensures the stability and accuracy of data during transmission.

[0035] Please see Figure 1 , Figure 3 and Figure 4 A screw 14 is rotatably connected to the inner wall of the support plate 4. A pressing plate 16 is threadedly connected to the outer surface of the screw 14. The outer surface of the pressing plate 16 is slidably connected to the support plate 4. A rotating wheel 15 is fixedly connected to the end of the screw 14 away from the support plate 4. When it is necessary to fix the electricity meter body 11, the operator only needs to hold the rotating wheel 15 and rotate it clockwise. The screw 14 will rotate accordingly, driving the pressing plate 16 to move along the axial direction of the screw 14 toward the electricity meter body 11 until the pressing plate 16 fixes the electricity meter body 11.

[0036] Please see Figure 1 , Figure 2 and Figure 3The outer surface of the support plate 4 has a slot 10, and the inner wall of the slot 10 is rotatably connected to a connecting plate 12. An infrared detector 13 is fixedly installed on the outer surface of the connecting plate 12. The connecting plate 12 is connected to the inner wall of the slot 10 by means of a rotating shaft and a miniature bearing. This design allows the connecting plate 12 to rotate freely. According to the actual testing needs, the staff can easily adjust the detection angle of the infrared detector 13 to ensure that all parts of the electricity meter body 11 can be tested in all directions.

[0037] Please see Figure 4 and Figure 5 The inner wall of the support plate 4 is slidably connected to two connecting rods 17. Each connecting rod 17 is fixedly connected to a locking block 20 at the end away from the support plate 4, and a slider 18 is fixedly connected to the end of each connecting rod 17 close to the support plate 4. By pulling the locking block 20, the locking block 20 will drive the corresponding connecting rod 17 to slide horizontally along the support plate 4. At this time, the connecting rod 17 will drive the corresponding slider 18 to slide horizontally along the support plate 4.

[0038] Please see Figure 5 Each connecting rod 17 has a spring 19 fitted on its outer surface. The ends of the two springs 19 that are close to each other are fixedly connected to the corresponding sliders 18, and the other ends are fixedly connected to the support plate 4. When the connecting rod 17 is pulled, the spring 19 will be compressed. When there is no external force, the spring 19 will push the corresponding slider 18 to reset under the action of its rebound force.

[0039] Please see Figure 5 Each of the two locking blocks 20 has a pull block 21 fixedly connected to one end of each block. The outer surface of each locking block 20 engages with the corresponding slot 3. When the locking block 20 is pulled and fully engaged in the slot 3, the elastic rubber strip will press tightly against the locking block 20, generating additional friction to prevent the locking block 20 from accidentally coming out during the test, thus enhancing the stability of the electricity meter.

[0040] This embodiment of a test fixture for an electricity meter communication interface includes an adjustable support plate 4. The support plate 4 can be adjusted during use, allowing the user to easily observe the test results. Pulling the pull block 21 causes the corresponding locking block 20 to move horizontally until the locking block 20 engages with the corresponding slot 3. This allows for quick and easy fixation of the support plate 4. Opening and closing the support plate 4 allows for neat and organized storage during use, facilitating transportation and reducing external damage to the support plate 4.

[0041] The working principle of the above embodiments is as follows:

[0042] First, pull the lever 21 to move the corresponding locking block 20 out of the corresponding slot 3. At this time, the spring 19 will be compressed. Then, rotate the support plate 4 around the connecting block 6. When the lever 21 is released, the spring 19 will push the corresponding slider 18 to reset under its rebound force. Then, by moving the support column 22 at the bottom of the support plate 4 to insert it into the fixing groove 2 on the inner wall of the fixing frame 1, the support plate 4 can be supported and fixed. At this time, the interface test modules 7 of different specifications are installed in the corresponding mounting holes 5 by using fixing bolts. Then, the energy meter body 11 is placed on the support plate 4. At this time, by rotating the rotating wheel 15, the screw 14 is rotated. At this time, the rotation of the screw 14 will drive the pressing plate 16 to fix the energy meter body 11. At this time, by rotating the connecting plate 12, the infrared detector 13 can be driven to scan the infrared detection module 8, and the communication interface is tested through the connection between the interface test module 7 and the communication test module 9.
