Description

Technical Field

[0001] This utility model relates to the field of fuel cell inspector testing technology, and more specifically, to a fuel cell inspector testing fixture. Background Technology

[0002] A fuel cell inspector is a device used to monitor fuel cell systems. It can collect parameters such as fuel cell stack voltage, temperature, and humidity in real time, analyze the data to determine the battery status, and promptly alarm when abnormalities occur, ensuring the safe and stable operation of the system and improving reliability and service life. The fuel cell inspector testing fixture is a specialized device for testing its performance. It consists of a simulated load and power supply, and can simulate working conditions to test and calibrate the inspector's measurement, communication, and alarm functions.

[0003] Publication No. (CN221572619U) discloses a fuel cell inspector testing fixture, including a base plate, at least three support columns, and a top plate. The base plate and top plate are symmetrically arranged vertically and connected by the support columns to form a rigid whole. The upper end of the top plate is provided with at least one horizontal limiting block and at least one vertical limiting block, which together form a rectangular groove. The rectangular groove is provided with a test integration plate, which is provided with at least one connector and at least one set of probe groups. The connector connects to the probe groups, and the probe groups include at least one contact probe, with each contact probe corresponding to a signal point of the connector. This application, compared with the prior art, eliminates frequent plugging and unplugging test operations by using corresponding contact and pressing connection of probe groups, saving test time and improving production efficiency.

[0004] However, this fuel cell inspector testing fixture has the following drawbacks: Long-term exposure of the probe to the outside environment allows dust and other impurities to accumulate, affecting its connection stability and detection accuracy. Dust and other impurities adhering to the probe form an isolation layer at the connection point between the probe and the object being tested. This can lead to poor contact between the probe and the connection point, resulting in loosening and increased contact resistance. Because the probe is easily contaminated by impurities due to prolonged exposure, more frequent cleaning and maintenance are required to ensure connection stability and detection accuracy. This increases the maintenance cost and workload, and may also cause some damage to the probe during maintenance, further affecting the equipment's performance. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a fuel cell inspector testing fixture to solve the problem that dust and other impurities will adhere to the probe when it is exposed to the outside for a long time, which will affect its connection stability and detection accuracy.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a fuel cell inspector testing fixture, comprising...

[0007] The detection body has a detection line fixedly connected inside. A detection connector is fixedly connected to one end of the detection line away from the detection body. A connecting plate is slidably connected to the outside of the detection line. A support plate is fixedly connected to one end of the connecting plate away from the detection line. A clamping plate is slidably connected to the inner wall of the support plate. A pressure plate is fixedly connected to the outside of the clamping plate. An elastic element is fixedly connected to one end of the pressure plate away from the clamping plate. A gasket is fixedly connected to one end of the clamping plate away from the pressure plate. A storage groove is provided on the inner wall of the detection body.

[0008] The inner wall of the connecting plate is slidably connected to a pressure column, the outside of the pressure column is fixedly connected to a pressure block, the outside of the pressure block is fixedly connected to an elastic element two, and the end of the pressure column away from the pressure block is fixedly connected to a locking block.

[0009] The outer side of the pressure block is slidably connected to the inner wall of the connecting plate, and the outer side of the second elastic element is in contact with the inner wall of the connecting plate.

[0010] The external locking block is engaged with the inner wall of the detection connector, and the external connecting plate is movably connected to the inner wall of the storage slot.

[0011] The support plate is externally movably connected to the inner wall of the storage groove, and the end of the elastic member of the pressure plate away from the pressure plate is fixedly connected to the inner wall of the support plate. The outside of the connecting plate is in contact with the outside of the detection connector.

[0012] The connecting plate is externally movably connected to the inner wall of the detection body, and the support plate is externally movably connected to the inner wall of the detection body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In the above scheme, the interface of the fuel cell inspector to be tested is connected to the test connector. The output line of the fuel cell inspector is clamped by two clamps. The clamps apply pressure to the elastic element through the pressure plate, so that the clamps can clamp the output line according to different thicknesses. The clamps also clamp the output line with the gaskets, which can increase the friction. This allows the interface of the fuel cell inspector to be stably and firmly connected to the test connector and tested, improving the stability and accuracy of the fuel cell inspector test. At the same time, when the test is completed, the test line and the connecting plate are stored in the storage groove by rotating the knob in the test body. By setting the length of the test line storage and release, it is more flexible to test fuel cell inspectors in some narrow spaces.

[0015] In the above scheme, when the connecting plate is stored, the two pressure columns are pinched to compress the elastic element two. The elastic element two then deforms and contracts, allowing the two locking blocks to merge. Subsequently, by moving the connecting plate in the detection line, the merged locking blocks are locked inside the detection joint, preventing dust from entering the detection joint, avoiding poor contact during docking detection, and extending the service life of the equipment.

[0024] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0025] As attached Figure 1 To be continued Figure 6 An embodiment of this utility model provides a fuel cell inspector testing fixture, including...

[0026] The testing body 1 has an internally fixed testing line 2. As the core component of the entire testing fixture, the testing body 1 serves to carry and control the testing functions. The fuel cell is a hydrogen-oxygen fuel cell stack, typically composed of multiple proton exchange membranes connected in series. The output voltage of each proton exchange membrane is generally below 1.2V. Therefore, this fixture consists of hundreds of voltage conversion modules connected in series, powered by 220V. Each module converts the voltage to 1.5V, and these hundreds of modules are connected in series to simulate a fuel cell stack. The voltage conversion modules output not only 1.5V but also other voltages, adjustable to meet customer needs. The fixture is rectangular in shape, with hundreds of connectors labeled 1-nn (representing the number of voltage conversion modules) next to the casing. These connectors connect a line leading from each voltage module to the voltage acquisition test line of the inspection controller. A function signal generator is connected in series with the hundreds of voltage conversion modules to simulate power supply noise interference during actual data acquisition. An external touchscreen display shows the amplitude and frequency of the function signal, the number of acquisition channels, and the output voltage value of the voltage conversion modules. It meets users' needs for single-item inspection and mixed-item inspection.

[0027] The detection line 2 is fixedly connected inside the detection body 1. It is the key channel for transmitting detection signals, responsible for conveying the instructions and feedback information from the detection body 1 to the fuel cell inspector under test. A detection connector 3 is fixedly connected to the end of the detection line 2 furthest from the detection body 1. The detection connector 3 is the part that directly interfaces with the fuel cell inspector. Its function is to establish an electrical connection between the detection line 2 and the fuel cell inspector. By connecting the interface of the fuel cell inspector under test to the detection connector 3, the detection body 1 can smoothly obtain the inspector's data for testing. A connecting plate 4 is slidably connected to the outside of the detection line 2. The connecting plate 4 can slide outside the detection line 2, increasing the flexibility of the tooling. During the testing process, its position can be adjusted according to actual needs, facilitating the testing of fuel cell inspectors in different positions and states, and also allowing for better operation during storage.

[0028] A support plate 5 is fixedly connected to the end of the connecting plate 4 furthest from the detection line 2. The support plate 5 is connected to the detection line 2 via the connecting plate 4, ensuring the stability of the entire clamping structure and allowing the clamping plate 6 to more effectively clamp the output line of the fuel cell inspector. The clamping plate 6 is slidably connected to the inner wall of the support plate 5. The clamping plate 6 can slide on the inner wall of the support plate 5. During testing, it can adjust its position according to the thickness of the fuel cell inspector's output line to effectively clamp output lines of different specifications, ensuring a stable connection between the output line and the detection connector 3.

[0029] A pressure plate 7 is fixedly connected to the outside of the clamping plate 6. The pressure plate 7 is fixedly connected to the clamping plate 6. When the position of the clamping plate 6 needs to be adjusted, force is applied to the pressure plate 7, causing the clamping plate 6 to slide within the support plate 5, thus achieving adaptive clamping for output cables of different thicknesses. An elastic element 8 is fixedly connected to the end of the pressure plate 7 away from the clamping plate 6. The elastic element 8 is connected between the pressure plate 7 and the inner wall of the support plate 5. The clamping plate 6 applies pressure to the elastic element 8 through the pressure plate 7, causing the elastic element 8 to deform. Utilizing its elastic force, the clamping plate 6 can adaptively clamp according to the output cable of different thicknesses, ensuring clamping stability.

[0030] A gasket 9 is fixedly connected to the end of the clamping plate 6 away from the pressure plate 7. The gasket 9 is fixed to the end of the clamping plate 6. When the clamping plate 6 clamps the output line of the fuel cell inspector, the gasket 9 increases the friction between the output line and the clamping plate 6, allowing the output line to be more stably clamped between the clamping plates 6. This ensures that the interface of the fuel cell inspector can be stably and firmly connected to the test connector 3, improving the stability and accuracy of the test. A storage groove 10 is provided on the inner wall of the test body 1. The storage groove 10 is located on the inner wall of the test body 1. When the test is completed, rotating the knob in the test body 1 allows the test line 2 and the connecting plate 4 to be stored inside the storage groove 10, facilitating the carrying and storage of the tooling and preventing damage to the test line 2 when not in use.

[0031] A pressure column 11 is slidably connected to the inner wall of the connecting plate 4. The pressure column 11 can slide on the inner wall of the connecting plate 4 and is a key component for controlling the movement of the locking block 14. By squeezing the pressure column 11, the locking block 14 can be joined and separated. A pressure block 12 is fixedly connected to the outside of the pressure column 11. The pressure block 12 is fixedly connected to the pressure column 11. When the pressure column 11 is squeezed, the pressure column 11 will drive the pressure block 12 to slide on the inner wall of the connecting plate 4, thereby applying pressure to the elastic element 13.

[0032] An elastic element 13 is fixedly connected to the outside of the pressure block 12. The elastic element 13 is connected between the pressure block 12 and the inner wall of the connecting plate 4. When the pressure block 12 is pushed by the pressure column 11, it compresses the elastic element 13, causing it to deform and contract, thus facilitating the merging of the locking block 14. When the external force disappears, the elastic element 13 returns to its original shape, driving the pressure block 12 and the pressure column 11 back to their initial positions. A locking block 14 is fixedly connected to the end of the pressure column 11 away from the pressure block 12. The locking block 14 is connected to the pressure block 12 via the pressure column 11. When the connecting plate 4 is being stored, squeezing the two pressure columns 11 causes the elastic element 13 to contract, allowing the two locking blocks 14 to merge. The merged locking blocks 14 are then locked inside the detection connector 3, preventing dust from entering the inside of the detection connector 3 and avoiding poor contact during docking testing.

[0033] The pressure block 12 is externally slidably connected to the inner wall of the connecting plate 4, and the outer side of the elastic element 13 is in contact with the inner wall of the connecting plate 4. The sliding of the pressure block 12 on the inner wall of the connecting plate 4 ensures the stability of its movement, allowing it to accurately apply pressure to the elastic element 13 when the pressure column 11 is squeezed. The contact between the elastic element 13 and the inner wall of the connecting plate 4 allows for better deformation under pressure, and it can accurately return the pressure block 12 to its initial position when restoring its original shape, ensuring the accurate and reliable operation of the locking block 14.

[0034] The external locking block 14 is engaged with the inner wall of the test connector 3, and the external movable connection plate 4 is engaged with the inner wall of the storage groove 10. The locking block 14 engages with the inner wall of the test connector 3 to protect it, preventing dust and other impurities from entering and ensuring the cleanliness and good electrical connection performance of the test connector 3. The movable connection plate 4 to the inner wall of the storage groove 10 allows the connecting plate 4 to smoothly enter the storage groove 10 when storing the test line 2, achieving complete storage of the tooling.

[0035] The support plate 5 is externally movably connected to the inner wall of the storage slot 10, and the pressure plate 7 is externally slidably connected to the inner wall of the support plate 5. The support plate 5 is movably connected to the inner wall of the storage slot 10, and during storage, it can enter the storage slot 10 along with the connecting plate 4 without affecting the tooling storage operation. The pressure plate 7 slides on the inner wall of the support plate 5, which can drive the clamping plate 6 to move, realizing an adaptive clamping function for output cables of different thicknesses.

[0036] The end of the elastic element 8 furthest from the pressure plate 7 is fixedly connected to the inner wall of the support plate 5, and the outer side of the connecting plate 4 is in contact with the outer side of the detection connector 3. The elastic element 8, fixed between the inner wall of the support plate 5 and the pressure plate 7, effectively provides elastic clamping force to the clamping plate 6. The contact between the connecting plate 4 and the outer side of the detection connector 3 ensures the stability of the connection between the detection line 2 and the detection connector 3 during the detection process, and also facilitates overall operation during storage.

[0037] The connecting plate 4 is externally and movably connected to the inner wall of the detection body 1, and the support plate 5 is externally and movably connected to the inner wall of the detection body 1. Both the connecting plate 4 and the support plate 5 are movably connected to the inner wall of the detection body 1, which allows them to move flexibly during detection and storage. This, combined with the storage and release of the detection line 2, ensures that the tooling maintains good performance and ease of operation under different working conditions.

[0038] The working process of this utility model is as follows:

[0039] First, the interface of the fuel cell inspector to be tested is connected to the test connector 3. The output line of the fuel cell inspector is held by two clamps 6. The clamps 6 apply pressure to the elastic element 8 through the pressure plate 7, so that the clamps 6 can hold the output line according to different thicknesses. The clamps 6 also hold the output line through the gasket 9, which increases the friction, so that the interface of the fuel cell inspector can be stably and firmly connected to the test connector 3 and tested by the main body 1, which improves the stability and accuracy of the fuel cell inspector test. At the same time, when the test is completed, the test line 2 and the connecting plate 4 are stored in the storage groove 10 by rotating the knob in the test body 1. By setting the storage and release length of the test line 2, it is more flexible to test fuel cell inspectors in some narrow spaces.

[0040] When the connecting plate 4 is stored, the two pressure columns 11 are pinched, causing the pressure blocks 12 in the two pressure columns 11 to squeeze the elastic element 13. At this time, the elastic element 13 deforms and contracts, allowing the two locking blocks 14 to merge. Then, by moving the connecting plate 4 in the detection line 2, the merged locking blocks 14 are locked inside the detection connector 3, preventing dust from entering the inside of the detection connector 3, avoiding poor contact during docking detection, and extending the service life of the equipment.
